] | The code you are showing does exactly one thing: attach action listeners to your buttons..
Meaning: when you click the button, then the listener will be called.
You need a generic keyboard listener that translates key events into calls to the appropriate button, respectively action listener instead. | When you do this:
```
button1.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent arg0) {
button1.keyPressed(KeyEvent.VK_1);
JOptionPane.showMessageDialog(f.getComponent(0), "Coffee selected");
}
});
```
You are telling `button1` what to do when somebody clicks on the button. The line with `keyPressed` should not be there (it does not compile even).
What you need to do is listen for key presses by adding a `KeyListener` to the frame like this:
```
f.addKeyListener(new KeyAdapter() {
@Override
public void keyTyped(KeyEvent e) {
if( e.getKeyChar() == KeyEvent.VK_1) {
JOptionPane.showMessageDialog(f.getComponent(0), "Coffee selected");
}
}
});
```
I repeated the `showMessageDialog`, but you should extract the actual logic into a method and call that method from within the `KeyListener` on the frame and the `ActionListener` on the button. |

] | From what I understand, essentially you want to have the same operation of a button assigned to a specific key stroke.
Things you want to avoid are `KeyListener`, especially because you have other focusable components in the view, namely buttons, which will steal keyboard focus and render the `KeyListener` useless. This is why, in almost all cases, you want to avoid `KeyListener`.
A better and more reliable solution would be to use the [Key Bindings API](https://docs.oracle.com/javase/tutorial/uiswing/misc/keybinding.html), which overcomes this focus related issue, but it also encourages the use of reusable components of work through the [`Action`s API](https://docs.oracle.com/javase/tutorial/uiswing/misc/action.html)
Something like...

Note, you could apply the key bindings directly to each button instead
Now, if you want to "visually" press the button on a key stroke, I would recommend either creating a custom `JButton` or factory method, which could allow for a more simplified implementation, but the basic idea would be to define a key binding and `Action` which simply called the buttons `doClick` method, for example

6,763,429 | i want to write a shape with " \* " and " | " the shape is below.
The program must take height and width from user.Width is column number without ' | '.I tried to write but confused.My code sometimes works great and sometimes being stupid.For example when i enter height : 13, width : 4 it writes one more,if witdh is 1 it enters infinite loop.While trying to solve it became too conflicted.Must i fix it or rewrite ?

Probably going to get downvoted for giving you a complete answer, but maybe it'll show you one correct approach and you can learn something from it... | It's better to rewrite. When you do, decouple the code into several functions so that one function draws a single line, and another one calls the former to draw all the lines. |

Sorry to all not doing others homework, but I couldn´t sleep without showing this *g* |
62,851,314 | Let me explain what is happening:
* Database: Oracle 19c
* Apex: 19.1.0.00.15
* ORDS standalone is 19.1.0.r0921545
I did the tasks to configure an Apex Social Sign In to Microsoft AAD without almost any issue:
* I created the authentication method in Apex.
* I register my application and get the web credentials in Azure.
* I created a wallet in my database with the root CA Microsoft certificates and configured the instance settings to usee that wallet.
* My wallet in the database server contains the property auto\_login to avoid using passwords.
* I created the ACEs entries to allow connection to the login.microsoftonline.com in the port 443
* Although it is not important for the purpose of the question itself and the error that is producing, just comment that I configured the wallet settings in the internal workspace in order to provide access to the wallet to the apex applications.
For some weeks the process was working fine, I was having a perfect Single Sing on mechanism for all my apex applications in the different workspaces. However, since some days ago, I am getting always the same error:
**ORA-29024: Certificate validation failure**
After some digging I realise that someone has configured a PROXY for outgoing traffic. Before even trying in Apex, I tried in SQL using APEX\_WEB\_SERVICE

My questions are the following:
* It is a network problem or a proxy issue regarding inbound/outbound
traffic ? I can reach Microsoft but not Google in the port 443 when I don't specify proxy.
* Why am I getting invalid certificate when it has nothing to do with
the certificates ?
* How can I setup my APEX to use authentication on Azure or any other
provider for that matter when I have a proxy in the middle ?
* As I use ORDS standalone, am I allow to keep using it or I need a
reverse proxy with Tomcat ?
I tried to configure the ACE to use HTTP\_PROXY in the ports by running
```
begin
sys.dbms_network_acl_admin.append_host_ace(
host => 'myproxyserver'
,lower_port => 8080
,upper_port => 8080

privilege_list => xs$name_list('http_proxy')
,granted => true
,principal_name => 'MY_PRINCIPAL'
,principal_type => XS_ACL.PTYPE_DB
)
);
end;
/
```
Even I grant to the ACE privileges over the wallet
```

but I am still getting the same error all over.
Any help would be appreciated!

* Database: Oracle 19c

I did the tasks to configure an Apex Social Sign In to Microsoft AAD without almost any issue:
* I created the authentication method in Apex.
* I register my application and get the web credentials in Azure.
* I created a wallet in my database with the root CA Microsoft certificates and configured the instance settings to usee that wallet.
* My wallet in the database server contains the property auto\_login to avoid using passwords.
* I created the ACEs entries to allow connection to the login.microsoftonline.com in the port 443

] | Thank you to all who post answers, but finally, after struggling for a while, I found the root cause. Actually Oracle was right after all, as Microsoft has changed the way the authentication is handled, either you are using Oauth2 or OpenID, when you use Office365 and Azure Active Directory.
In this case, my organisation is using Office 365 and at the beginning was enough with importing the PKI certificates from :
<https://www.microsoft.com/pki/mscorp/cps/default.htm>
After a change done in Azure Active Directory (AAD), you now need also the Global Sign certificates from [office.com](http://office.com)
I hope it clarifies to other users who got in the same problem trying to authenticate with Azure Active Directory using Apex Social sign in.
You can download the certificates directly from office365.com

After adding the new two certificates to the wallet, you can now enter without issues:

] | Our old friend `strace` solves this mystery.
In the `fflush("cat")` case, awk quickly writes all three values while cat is still loading. When cat finishes loading, it reads all three values in sequence and writes them out at the same time.
In the case of `close("cat")`, awk waits for the process to exit, at which point cat is guaranteed to have read the value, written it, and exited.
I increased the numbers in the `fflush` case from 3 to 1000, and now `awk` reaches 120 before cat catches up, and from there on it works basically as you expect. It prints "1,2,..,120,1,2,...,120,121,121,122,122,123,123,...".
Note that you're not guaranteed to see numbers in perfect pairs. awk blocks until the number has been written to the pipe, but it doesn't wait for cat to do anything with it. | Not really something I have much experience of but the gawk manual tells us:
>
> fflush([filename])
> Flush any buffered output associated with filename,
> which is either a file opened for writing or a shell command for
> redirecting output **to a pipe** or coprocess.
>
>
>
Note that "cat" as used above is in none of the contexts the gawk manual says are affected by fflush().
The same manual for close() on the other hand says:
>
> close(filename [, how])
> Close the file filename for input or output.
> Alternatively, the argument may be a shell command that was used for
> creating a coprocess, or for redirecting **to or from a pipe**; then
> the coprocess or pipe is closed.
>
>

Note that the context in which you're using cat is redirecting **from** a pipe and so is included in the list of items affected by close() but not by fflush(). |

This effects the PE recovery environment & will break the factory recovery. Even after reapplying the Factory.wim of windows 7 and it blue screens, Windows 10 PE recovery environment will start & not help with the start up issues. I'm presently trying to undo all of this on a Dell Inspiron laptop at present.
I don't think this will happen if there is a 100MB system partition on the drive as this is where the Windows 10 recovery environment will install (in the boot folder). Thus leaving the Dell Recovery partition untouched leaving the F11 function in tact to be able to factory install the OS that shipped with the laptop. Isn't the digital life wonderful!!! | If you run into a problem where you cannot access your recovery partition, or the partition is deleted, you can run a tool called DSRFIX and it should restore the recovery partition. |
418,342 | I know I can pass parameters to java to limit the amount of memory used, but that doesn't change the application behavior. (assuming I will get an out of memory exception or similar)
I would like to limit the amount of memory that solr uses. I am assuming it is as simple as setting a single configuration option, but googling so far has been fruitless.
Any ideas? Thanks!
Edit: I just want to note that I understand there will be a tradeoff between memory usage and execution speed. In this case, I am willing to sacrifice speed to reduce memory footprint. I also understand that it is possible that solr does not support the option of tuning this tradeoff. | 2012/08/16 | [

I want to be able to log the start and end times of any seeks within the plaback, so we know if the user has not actually watched a section of the video. The player seems to offer events to support this, but I am struggling to get correct timings from it.
When the user skips through a video the player emits the following events in order: pause, seeking, seeked, play.
If I query the player object at any of these events using currentTime() the result is always the end time for the seek, even on the initial pause event. This means I can log where the seek ended but not where it started.
Can anyone help me to find the position in the video where the seek begins?
If this is not possible, I'd settle for a way to disable seeking during playback.

This seems to work with the HTML5 tech. I have not tested with other techs.
There is, however, one glitch: the first time seeking a *paused* player yields only a small delta (and the almost-same previous value for both variables). But this shouldn’t matter much since the delta is only a few hundred milliseconds (and I gather you’re only interested in the “from” value).
**Update**
`seeked` is triggered far more infrequently than `seeking`. Try the following.
```
var previousTime = 0;
var currentTime = 0;
var seekStart = null;
trackedPlayer.on('timeupdate', function() {
previousTime = currentTime;
currentTime = trackedPlayer.currentTime();
});
trackedPlayer.on('seeking', function() {

Initially, I thought to save the currentTime() a user was seeking **from** on **timeupdate** then immediately removing my timeupdate listener once **seeking** was dispatched.

] | For a more accurate solution, you can listen to the events that trigger the seek such as mousedown on progress bar, left key, right key etc., and get the current time from these events.
For example in version 7.10.2 you can do the following,
```
let seekStartTime;
player.controlBar.progressControl.on('mousedown', () => seekStartTime = player.currentTime());
player.controlBar.progressControl.seekBar.on('mousedown', () => seekStartTime = player.currentTime());
player.on('keydown', (e) => {
if (e.key === "ArrowLeft" || e.key === "ArrowRight") {
seekStartTime = player.currentTime();
}
});
console.log(seekStartTime);
```
**Note 1:** There are two seperate mousedown event listeners for progress control and seek bar. This is because the video can be seeked by clicking outside the seek bar on the progress control as well.
**Note 2:** Seeking using hotkey numbers does not pause the video. However, if necessary you can add those keydown listeners too. | Try with this code to know the length of video.

});

This seems to work with the HTML5 tech. I have not tested with other techs.
There is, however, one glitch: the first time seeking a *paused* player yields only a small delta (and the almost-same previous value for both variables). But this shouldn’t matter much since the delta is only a few hundred milliseconds (and I gather you’re only interested in the “from” value).
**Update**
`seeked` is triggered far more infrequently than `seeking`. Try the following.
```
var previousTime = 0;
var currentTime = 0;
var seekStart = null;
trackedPlayer.on('timeupdate', function() {
previousTime = currentTime;
currentTime = trackedPlayer.currentTime();
});
trackedPlayer.on('seeking', function() {
if(seekStart === null) {
seekStart = previousTime;
}
});
trackedPlayer.on('seeked', function() {
console.log('seeked from', seekStart, 'to', currentTime, '; delta:', currentTime - previousTime);
seekStart = null;
});
```
There are also many libraries for debouncing function calls (in this case the call to your backend). | For a more accurate solution, you can listen to the events that trigger the seek such as mousedown on progress bar, left key, right key etc., and get the current time from these events.
For example in version 7.10.2 you can do the following,
```
let seekStartTime;
player.controlBar.progressControl.on('mousedown', () => seekStartTime = player.currentTime());
player.controlBar.progressControl.seekBar.on('mousedown', () => seekStartTime = player.currentTime());
player.on('keydown', (e) => {
if (e.key === "ArrowLeft" || e.key === "ArrowRight") {
seekStartTime = player.currentTime();
}
});
console.log(seekStartTime);
```
**Note 1:** There are two seperate mousedown event listeners for progress control and seek bar. This is because the video can be seeked by clicking outside the seek bar on the progress control as well.
**Note 2:** Seeking using hotkey numbers does not pause the video. However, if necessary you can add those keydown listeners too. |
29,743,729 | I am using video.js (<http://www.videojs.com/>) to build a video approval system and need to log user actions in the player. I can do this easily enough with play, pause, end etc. but have hit a problem when trying to log seeks.
I want to be able to log the start and end times of any seeks within the plaback, so we know if the user has not actually watched a section of the video. The player seems to offer events to support this, but I am struggling to get correct timings from it.
When the user skips through a video the player emits the following events in order: pause, seeking, seeked, play.
If I query the player object at any of these events using currentTime() the result is always the end time for the seek, even on the initial pause event. This means I can log where the seek ended but not where it started.
Can anyone help me to find the position in the video where the seek begins?
If this is not possible, I'd settle for a way to disable seeking during playback.
EDIT: adding code as requested. It's pretty simple:
```
var trackedPlayer = videojs('pvp-player');
trackedPlayer.on("play", function (e) {
console.log("Video playback started: " + trackedPlayer.currentTime());
});
trackedPlayer.on("pause", function (e) {
console.log("Video playback paused: " + trackedPlayer.currentTime());
});
trackedPlayer.on("seeking", function (e) {
console.log("Video seeking: " + trackedPlayer.currentTime());

Unfortunately, the English-only CTP does not support German VS.
The "compiler driver" cl.exe is what invokes the compiler front-end c1xx.dll, the compiler back-end c2.dll, and the linker link.exe. It is very unusual for the compiler driver to crash. I speculate that it's attempting to display one of the error messages that were added by the CTP, but since the CTP didn't update the German resources, the compiler driver can't load the error message and proceeds to crash.
Note that this is different from an Internal Compiler Error in the front-end or back-end, or a normal compiler error that happens to be incorrectly emitted. (Many ICEs and bogus errors have been fixed after the CTP was released.)

The CTP installed <initializer\_list> in a special location. (It was actually written by the compiler team.)
On the command line, the incantations to use the CTP and put <initializer\_list> on the include path are (assuming default locations):
```
"C:\Program Files (x86)\Microsoft Visual Studio 11.0\VC\vcvarsall.bat" x86

You may be interested to learn that we've updated the standard library to fully support scoped enums and initializer lists. This includes all initializer\_list overloads mandated by the current Working Paper (N3485), plus installing <initializer\_list> in the usual location along with all other standard headers. (It is also Dinkumware's official copy, although the differences between it and the compiler team's "fake" version were mostly cosmetic.) This stuff will be available in the next public release, whenever and whatever that is. Our next task is to update the standard library with explicit conversion operators and variadic templates, replacing our brittle simulations. | As you have noticed, the November CTP is very limited in usability for at least two reasons:
1. The compiler has numerous crash-causing bugs, such as the one you discovered.
2. The C++ Standard Library was not updated with the compiler, leaving you without decent `<tuple>` and `<intializer_list>` (this includes the omission of the braced init list constructors for *all* standard containers)
Also: the linked example is very ugly code. If you want to use this feature, use a compiler like GCC or Clang that supports this syntax. They are both available for Windows. Hacking around a half-implemented language feature by writing extra code is just stupid. |
19,995 | I don't recall ever having the problem with the iron before, but it's been a few years since I used it, as I'm just getting back into some projects since my Electronics degree.
I bought some solder for a new project (I need a lot) and it's lead-free:
```
95% Tin
4% Silver
1% Copper
```
Now, I'm not sure how tolerant the values are for melting point but I can say that it does appear to act Eutectic, like the known combination 95.5/4/0.5 ([Indalloy 246](http://www.matweb.com/search/DataSheet.aspx?MatGUID=19662ece2a4a4bb2bbe7aa522f916185)) which has a melting point of 217 degrees Celcius.
According to the manufacturer of my Iron (Antex) it has a tip temperature of 370 celcius.
I sanded down the tip yesterday with a fine grain metal sanding paper to see if the tip just needed cleaning, however it's now gone "black" instead of the shiny silver it was when I first sanded it.
The real question I wonder is where the problem lies, is it that my tip is dead, is my iron too low power or is it just that my iron is dead.
I ask because I need to know whether to replace the iron, the tip or a higher power iron. My preference is to stick with the Antex irons, and I prefer "precision" bits like the on in my current iron, so, what are the recommendations? | 2011/09/25 | [

] | Your tip is dead since you have now sanded off the special coating. It will of course still get hot, but will oxidize rapidly so that solder won't wick onto it. This will make it very difficult to solder with.
You say the tip is supposed to be 370C (700F), but is that temperature controlled or just some open loop guess? 12W sounds very low for a temperature controlled soldering station, and also not enough to heat much beyond a little solder and a wire or two at the same time. For example, my Weller WES51 temperature controller soldering station has a 50W iron. Of course most of the time it's not run at 50W, but that's what the control algorithm can cause it to put out when it senses low tip temperature.
Since you just destroyed your tip (and the iron if it has a fixed tip), maybe it's time to get a real one that has temperature control. | A 12w iron is way under-powered for leadfree. You need a temerature-controlled iron, 40-60W minimum |

] | A slightly quicker step (2) skips the quadratic formula: Observe that the hypotenuse shared by your two 30-60-90 triangles has length $\frac 2{\sqrt 3} r$ (since the side lengths are proportional to $1:\sqrt 3:2$), hence
$$r + \frac 2{\sqrt 3}r = 1$$
which yields $r=2\sqrt 3-3$. | Here's my approach for the problem:
Please note that my answer uses a lemma that can be proven easily, that is, [the radii of two externally or internally tangent circles are collinear](https://youtu.be/0whTkdGBNn0).
[](https://i.stack.imgur.com/R518H.png)
1.) First, we join the center of the semicircle with that of the circle, and draw a perpendicular from the center of the circle to the tangent points (semicircle and the vertex of the equilateral triangle). Notice that the two triangles that are formed are congruent via the SSS property, therefore we can conclude that the line connecting two centers is an angle sector. This proves that the two triangles are in fact "$30-60-90$" triangle.
2.) Now, using the fact proven above, we can say that the base of those triangles (i.e. the side opposite to the $30^\circ$ angle) is $\frac{r}{\sqrt3}$. Finally, we can finish off the problem:
$$(1-r)^2=r^2+(\frac{r}{\sqrt3})^2$$
$$1-2r+r^2=r^2+\frac{r^2}{3}$$
$$r^2+6r-3=0$$
Since this isn't factorable, we can use the quadratic formula:
$$r=\frac{-6±\sqrt{48}}{2}$$
Since $\frac{-6-\sqrt{48}}{2}$ would be negative, we must reject that. Therefore:
$$r=-3+2\sqrt{3}$$ |

You could use a different constructor, say `TObject (int i)` by writing

So, in short, you don't need to mention the name of the base class destructor in the derived class destructor. As soon as you destroy the derived object (say, by doing `delete derivedObj`), it will first call the derived class destructor and then base class destructor by itself. |

To have the decision on what destructor to call deferred to runtime, you need to specify the destructor as `virtual` in `TObject`.

===================
As explained by others it has no basic, default, means of expressing language. It's not about learning the language, it's the capability of the spell/energy powering the skeleton(s). Undeath is not in itself an impediment to speech (see: Liches).
Therefore you need to extrapolate a bit. The RAW description quoted above seems to imply the power source provides bare-minimum world interaction capabilities. And does not extend to advanced capabilities like mimicking a voice (disembodied or otherwise).
But, the "talking skull/skeleton" trope is incredibly common. So...
By customization, yes. (Possibly with the aid of a magic item.)

It is your game, after all. And creativity is a core value of the gaming experience.
A skeleton is already magically animated, so if you wanted a **specific skeleton** to have the ability to speak, there are several creative ways you could explain the phenomenon.
* A magic item equipped by its creator, or even left over from its previous life. (An enchanted ring or amulet?)
* A slightly more powerful skeleton who gained the ability to speak over time via wild magic or the like.
* A skeleton created with extra riders on the creation spell by its creator. So maybe it was imbued with a secondary spell to allow a disembodied voice.
You could have all skeletons speak of that's how you want to run your world, but that'd be your own custom flavoring.
A speaking skeleton, otherwise, would be **special for some reason**. |

... but both of these interpretations seem to be relatively 'new' 5e expansions to d&d skeleton lore. Wrt Habitual Behaviors in the 5e MM, if "skeletons of nobles might continue in an eternally unfinished dance" && "can load and fire a catapult or trebuchet".
Also, wrt D&D Beyond, it appears to be poorly worded. If taken literally, that it simply cannot speak; then it would be able to use sign language, portions of thieves cant, or write & still communicate.
I think all of the older versions are more consistent wrt skeletons in this respect; in that the creator can command them via magic (and it ignores the medium of the command.)
Therefore we need to break up your question:
1. Can it not speak because of its undeath?
If you look at all the lore in total, the answer here would be the skeleton cannot "communicate", speaking or otherwise. If you look at 5e literally, then the two sources are possibly contradictory & you'll have to subjectively decide for your world/campaign.
2. Could it learn to speak a language?
The simple answer is no... however, again looking at all the lore, should a different necromancer, demon, etc gain control of the skeleton; the method of control would give the ability to command irrespective of language.
Relatedly, an item of consideration is whether or not skeletons are deaf, & how their "vison" works.?. In my campaigns, skeletons are "unintelligent", and are deaf; with their "vision" being more animalistic/primitive in nature (they can't read, or understand complex items <missle weapons & doors included>)...

] | By RAW default, no.
===================
As explained by others it has no basic, default, means of expressing language. It's not about learning the language, it's the capability of the spell/energy powering the skeleton(s). Undeath is not in itself an impediment to speech (see: Liches).
Therefore you need to extrapolate a bit. The RAW description quoted above seems to imply the power source provides bare-minimum world interaction capabilities. And does not extend to advanced capabilities like mimicking a voice (disembodied or otherwise).
But, the "talking skull/skeleton" trope is incredibly common. So...
By customization, yes. (Possibly with the aid of a magic item.)
===============================================================
It is your game, after all. And creativity is a core value of the gaming experience.
A skeleton is already magically animated, so if you wanted a **specific skeleton** to have the ability to speak, there are several creative ways you could explain the phenomenon.
* A magic item equipped by its creator, or even left over from its previous life. (An enchanted ring or amulet?)
* A slightly more powerful skeleton who gained the ability to speak over time via wild magic or the like.
* A skeleton created with extra riders on the creation spell by its creator. So maybe it was imbued with a secondary spell to allow a disembodied voice.
You could have all skeletons speak of that's how you want to run your world, but that'd be your own custom flavoring.
A speaking skeleton, otherwise, would be **special for some reason**. | It is true, on pg 272 of the 5e Monster Manual, it states:

... but both of these interpretations seem to be relatively 'new' 5e expansions to d&d skeleton lore. Wrt Habitual Behaviors in the 5e MM, if "skeletons of nobles might continue in an eternally unfinished dance" && "can load and fire a catapult or trebuchet".
Also, wrt D&D Beyond, it appears to be poorly worded. If taken literally, that it simply cannot speak; then it would be able to use sign language, portions of thieves cant, or write & still communicate.
I think all of the older versions are more consistent wrt skeletons in this respect; in that the creator can command them via magic (and it ignores the medium of the command.)
Therefore we need to break up your question:
1. Can it not speak because of its undeath?
If you look at all the lore in total, the answer here would be the skeleton cannot "communicate", speaking or otherwise. If you look at 5e literally, then the two sources are possibly contradictory & you'll have to subjectively decide for your world/campaign.
2. Could it learn to speak a language?
The simple answer is no... however, again looking at all the lore, should a different necromancer, demon, etc gain control of the skeleton; the method of control would give the ability to command irrespective of language.
Relatedly, an item of consideration is whether or not skeletons are deaf, & how their "vison" works.?. In my campaigns, skeletons are "unintelligent", and are deaf; with their "vision" being more animalistic/primitive in nature (they can't read, or understand complex items <missle weapons & doors included>)...
This isn't to say a specific necromancer couldn't craft a "unique breed" of skeletons that have different features, including higher intelligence; but just that the "average" skeleton does not. |

[Explanation](https://i.stack.imgur.com/3Y15r.jpg) |
11,615,082 | I'm trying to run a macro that will delete rows that don't contain a particular value in column B. Here's my code:
```
Sub deleteRows()
Dim count As Integer
count = Application.WorksheetFunction.CountA(Range("AF:AF"))
Dim i As Integer
i = 21
Do While i <= count
If (Application.WorksheetFunction.IsNumber(Application.WorksheetFunction.Search("OSR Platform", Range("B" & i))) = False) Then
If (Application.WorksheetFunction.IsNumber(Application.WorksheetFunction.Search("IAM", Range("B" & i))) = False) Then
Rows(i).EntireRow.Delete
i = i - 1
count = count - 1
End If
End If
i = i + 1
Loop
End Sub
```
Now what it SHOULD be doing is the following:
1.) Find the number of rows to go through and set that as count (this works)
2.) Start at row 21 and look for "OSR Platform" and "IAM" in column B [this kind of works (see below)]
3.) If it finds neither, delete the entire row and adjust the count and row number as necessary (this works)
For some reason, whenever the code gets to the first If statement, an error window with a red X pops up that just says "400." As far as I can tell, I have written everything syntactically soundly, but clearly there's something wrong. | 2012/07/23 | [

] | You may want to start by looping the other way. When you delete a line, all the previous lines are shifted. You account for this, but a reverse loop is simpler (*for me anyways*) to understand than keeping track of when I've offset the current position within the loop:
`For i = count To 21 Step -1`
Also, you're relying too much on `Application.WorksheetFunction`:
`(Application.WorksheetFunction.IsNumber(Application.WorksheetFunction.Search("OSR Platform", Range("B" & i))) = False)`
to
`InStr(Range("B" & i).value, "OSR Platform") > 0`
`Application.WorksheetFunction` takes much more processing power, and depending on what you are trying to accomplish, this can take a significantly longer amount of time. Also for this suggested change, the code size is reduced and becomes easier to read without it.
Your `count` can also be obtained without `A.WF`:
* Excel 2000/03: `count = Range("AF65536").End(xlUp).Row`
* Excel 2007/10: `count = Range("AF1048576").End(xlUp).Row`
* Version independent: `count = Range("AF" & Rows.Count).End(xlUp).Row`
One more thing is that you can do (and *should* do in this case) is combine your `If` statements into one.
Making these changes, you end up with:
```
Sub deleteRows()
Dim count As Integer
count = Range("AF" & Rows.Count).End(xlUp).Row
Dim i As Integer
For i = count To 21 Step -1
If Len(Range("B" & i).value) > 0 Then
If InStr(Range("B" & i).value, "OSR Platform") > 0 Or InStr(Range("B" & i).value, "IAM") > 0 Then
Range("B" & i).Interior.Color = RGB(255, 0, 0)
End If
End If
Next i
End Sub
```
If this does not help, then can you step through the code line by line. Add a breakpoint, and step through with `F8`. Highlight the variables in your code, right-click, choose "add Watch...", click "OK", ([Here's an excellent resource to help you with your debugging in general](http://www.cpearson.com/excel/debug.htm)) and note the following:
* Which line hits the error?
* What is the value of `i` and `count` when that happens? (add a watch on these variables to help) | This worked for me. It uses AutoFilter, does not require looping or worksheet functions.
```
Sub DeleteRows()
Dim currentSheet As Excel.Worksheet
Dim rngfilter As Excel.Range
Dim lastrow As Long, lastcolumn As Long
Set currentSheet = ActiveSheet
' get range
lastrow = currentSheet.Cells(Excel.Rows.Count, "AF").End(xlUp).Row
lastcolumn = currentSheet.Cells(1, Excel.Columns.Count).End(xlToLeft).Column
Set rngfilter = currentSheet.Range("A1", currentSheet.Cells(lastrow, lastcolumn))
' filter by column B criteria
rngfilter.AutoFilter Field:=2, Criteria1:="<>*OSR Platform*", Operator:= _
xlAnd, Criteria2:="<>*IAM*"
' delete any visible row greater than row 21 which does not meet above criteria
rngfilter.Offset(21).SpecialCells(xlCellTypeVisible).EntireRow.Delete
' remove autofilter arrows
currentSheet.AutoFilterMode = False
End Sub
```
This code applies AutoFilter to column B to see which rows contain neither "OSR Platform" nor "IAM" in column B. Then it simply deletes the remaining rows greater than 21. Test it on a copy of your workbook first.
With a huge nod to [this OzGrid](http://www.ozgrid.com/forum/showthread.php?t=153994) thread, because I can never remember the proper syntax for selecting visible cells after filtering. |

] | **First,** this section of scripture first appeared nearly 2,000 years ago, and was written to Christians who were surrounded by pagans who had a practice of presenting (offering) meat to their idols before taking it to the market to be sold as food. Therefore, when you ask, "Should ***we*** eat food sacrificed to idols?" you have jumped nearly 2,000 years to this day and age, I presume. I take it that you are asking Christians in the Year of our Lord 2023 whether to eat food sacrificed to idols, or not.
**Second**, where I live, I have no awareness of any food being presented before idols prior to being made available to anyone to buy. If you know of such practices, it would be helpful to either state a case (as an example of the pertinence of this question today) or to give a list of modern-day countries where this happens.
**Third,** ***the simple answer to your question*** (irrespective of any time from the middle of the first century A.D. until today) ***is "No, Christians should not."*** The matter is known to God, even if no other human knows you have eaten food that had been offered before an idol. ***Once you know, you are culpable, and God knows.*** Christians are to do everything (including their eating and drinking) for the glory of God. But, as the passage shows, there's no need to first hold an inquisition about it, asking questions, ferreting out individuals who might be suspected of the pagan practice and checking if a particular piece of food had been handled by them.
That section of scripture, however, has more to say on the matter than just that bit about food presented before an idol. It speaks of not eating meat that has not first been bled. But you do not ask about that, so I will end my answer here. | The rationale for Paul's advice comes from the principle in v21; "You cannot partake of the table of the Lord and [also] of the table of demons".
This follows on from vv 18-20. Israel were "partners in the altar" (v18, RSV) when they sacrificed, in that God and the worshippers both had their own shares in most of the sacrificed animals. Conversely, those who shared in the communal sacrificial meals of other gods were "partners with demons" (v20). It was necessary to choose. The same choice remains for Christians in that we now share in the "Lord's Supper", at the table over which the Lord presides. We must choose one or the other. The point is that we must avoid sharing in the worship of other gods, by participating in the their communal meals, and we must also avoid giving other people the impression that we are particpating indirectly.
If nobody else is involved, it seems to me that the deciding factor is what you yourself think you are doing if you get hold of meat which was previously "dedicated" to some other god. If you think you are participating in the original sacrificial meal, you are in the position of ch8 v7; "Some... eat food as really offered to an idol; and their conscience, being weak, is defiled."
But if you are giving thanks to God for your food (ch10 v30) and are confident that its previous history doesn't affect its value in the sight of God, then you are in the position of "liberty" in ch8 v8; "Food will not commend us to God". The dictum of ch10 v25, "Eat whatever is sold", can still apply even if we have asked the question anyway. In other words, it makes no difference one way or the other, unless we think it makes a difference. See the principle that runs through Galatians; we are living in liberty, not under law. |

] | **TL;DR:** There is no reason we should care whether our food has been sacrificed to idols.
The underlying idea here is whether one is committing idolatry, which is the belief that anything, other than God or his agents, has any supernatural power or attribute.
Believing that a rabbit's foot provides good luck is a form of idolatry, but so is believing that food that has been sacrificed to an idol is somehow different from food that hasn't.
Neither the rabbit's foot nor the food have any supernatural attributes.
To avoid something because it is reputed to have a non-existent attribute is equivalent to admitting that it *does* have that attribute.
For you, it shouldn't matter at all whether the food was sacrificed, any more than you should care what the phase of the Moon is today, or what constellation was in the sky at your birth.
But, if someone gives you something and explicitly or implicitly tells you it has supernatural attributes, *then* you should refuse it.
Not because it makes any difference to you, but because it makes a difference to the other person.
By taking it, you are implicitly endorsing and encouraging false beliefs, rather than providing the good example that every Christian should be.

] | **TL;DR:** There is no reason we should care whether our food has been sacrificed to idols.
The underlying idea here is whether one is committing idolatry, which is the belief that anything, other than God or his agents, has any supernatural power or attribute.
Believing that a rabbit's foot provides good luck is a form of idolatry, but so is believing that food that has been sacrificed to an idol is somehow different from food that hasn't.
Neither the rabbit's foot nor the food have any supernatural attributes.
To avoid something because it is reputed to have a non-existent attribute is equivalent to admitting that it *does* have that attribute.
For you, it shouldn't matter at all whether the food was sacrificed, any more than you should care what the phase of the Moon is today, or what constellation was in the sky at your birth.
But, if someone gives you something and explicitly or implicitly tells you it has supernatural attributes, *then* you should refuse it.
Not because it makes any difference to you, but because it makes a difference to the other person.
By taking it, you are implicitly endorsing and encouraging false beliefs, rather than providing the good example that every Christian should be.

I think I'm doing something wrong in the syntax of the Except method could anyone help me out? | 2016/01/16 | [

] | There are two ways to compare (for equality) two `Results` objects (and all reference type objects in general):
* The first way is to compare the values of the properties of the two `Results` objects.
* The second way is to compare the references themselves. And by that I mean that two `Results` objects are equal if they are actually a single object but you have two references to it. For example, you can create a single `Results` object and put it in two lists.
The objects in the two lists are clearly different objects, so I am guessing that you want to use the first way of comparison.
By default, equality check of reference type objects in C# is of the second type. However, you can override this behavior if you want.
One way of overriding this behavior is to override the `Equals` and `GetHashCode` methods in the class. Here is an example:
```
public class Results
{
public string url { get; set; }
public string title { get; set; }
public override bool Equals(object obj)
{
Results other = obj as Results;
if (other == null)
return false;
return other.url == this.url && other.title == this.title;
}
public override int GetHashCode()
{
return new {url, title}.GetHashCode();
}
}
```
This way, we are telling the system how it should test equality for objects of this type. | I'm sure Yacoub's answer would work and is probably the preferred solution in most cases, but in case you can't modify the Results class, here is another way to do it. Define an implementation of IEqualityComparer for Results, and then pass it as the second argument of the Except method.
EDIT:
```
class Results {
public string FirstName { get; set; }
public string LastName { get; set; }
}
class ResultsEqualityComparer : IEqualityComparer<Results> {
public bool Equals(Results res1, Results res2) {
return (res1.FirstName == res2.FirstName && res1.LastName == res2.LastName);
}
public int GetHashCode(Results res) {
return new { res.FirstName, res.LastName }.GetHashCode();
}
}
```
// and here's the example of code passing the ResultsComparer to Except:
```
var resultaten = new List<Results>() {
new Results() {FirstName="Bob", LastName="Smith"},
new Results() {FirstName="Ted", LastName="Wilson"},
new Results() {FirstName="Alice", LastName="Wilson"},
new Results() {FirstName="Carol", LastName="Smith"}
};
var resultaten2 = new List<Results>() {
new Results() {FirstName="William", LastName="Smith"},
new Results() {FirstName="Ted", LastName="Wilson"},
new Results() {FirstName="Gerhardt", LastName="Wilson"},
new Results() {FirstName="Carol", LastName="Smith"}
};
var comparer = new ResultsEqualityComparer();
List<Results> Veranderingen = resultaten2.Except(resultaten, comparer).ToList();
foreach (var x in Veranderingen) {
Console.WriteLine(x.FirstName + " " + x.LastName);

] | I come from the mindset that no law is strictly physical/spiritual. They blur into one another and provide benefits which merge those aspects.
Fasting is powerful in a spiritual sense because you are choosing to take control of a baser instinct. Hunger is as basic as breathing or sleepiness, so by choosing to overrule that instinct in reflection of a spiritual observance/exercise you are strengthening your divine traits and suppressing primal traits. Torah teaches that the **Nefesh HaBehamit** "animal soul" is in conflict with our **Nefesh Ha'elokit** (divine soul)
If you are interested in a more detailed explanation of the parts of the soul, you can read more in the Tanya at this link:
**<http://www.chabad.org/library/tanya/tanya_cdo/aid/7880/jewish/Chapter-1.htm>**
These comprise two different sections of our soul which are in a battle for control. By doing spiritual exercises (such as fasting) you can drive down the animalistic urges and raise yourself to a higher state of craving. You can move from craving that which is harmful to craving that which is beneficial if you practice and focus your time/energy. Fasting is just one of those exercises.
Fasting also has a symbolism associated with it in relation to the pain that hunger causes. When we observe **Tisha B'Av** (just one example) we fast. This holiday is a memorial in reflection various wrongs of Jewish history. One of the main reflections is on the loss of the holy temples (first and second).
Some reading regarding Tisha B'Av and the tradition of the observance:
**<http://www.chabad.org/library/article_cdo/aid/946703/jewish/What-happened-on-the-Ninth-of-Av.htm>**
This hunger pain is symbolic of the spiritual pain of our people. We sit in hunger and reflect on this pain and attach that pain to the wrongs and errors of Jewish history. By doing that, we take an impersonal history and we connect to it. I can't know what it was like to lose the holy temple because I never had the holy temple. That doesn't mean I can't reflect on what that loss has done to my ancestors and my peers of today.
By connecting the pain of our people to a pain which is rooted in our biology, we groom ourselves to make the suffering of our past a part of who we are. That strengthens us and drives us to honor the past, make peace with the present, and overcome the trials and tribulations of the future.
A very detailed reading regarding the purpose of fasting in relation to Judaism:
**<http://www.aish.com/atr/What_is_the_Purpose_of_Fasting.html>**
**From a physical/scientific standpoint.**
Fasting has been found to promote health benefits when done in a controlled manner over regulated periods of time. They recently discovered that if an individual fasts for a period of three days, their immune system resets itself.
**<http://www.telegraph.co.uk/science/2016/03/12/fasting-for-three-days-can-regenerate-entire-immune-system-study/>**
Your body uses the time without food to correct issues on a biological level.
Keep in mind, these are controlled fasts which are not extended beyond this period of time. Going beyond this period of time can harm you if you withhold sustenance for too long. Our bodies need nutrition to function correctly. | Fasting is a way of attaining a more spiritual state/frame of mind by disconnecting from physical pleasures. This more spiritual state is more conducive to Teshuva. See Nesivos Olam: Nesiv Hateshuva chapter 7 (beginning from the second paragraph) and Derech Hashem part 4 chapter 8:5 (regarding Yom Kippur).
However, today it is not recommended to fast (apart from the biblically/rabbinically mandated fasts) because it weakens the body and impairs the ability to think and learn Torah (Krina D'igrissa 1:16,17). |

It should also bring home the thought whether what made it possible for us to control our impulses and cravings - or, at any rate, the most pressing ones - for one day, could not make it possible for every day; and if we cannot control all such impulses, then at least we should shun the impure, the exuberant and the forbidden.

] | ***"Ты хочешь опят?"*** и ***"Ты хочешь опята?"*** - оба варианта возможны. Первое сейчас употребляется много чаще. Но это частота определяется не столько даже разницей в смысле (она есть, но не четкая), сколько традицией и аналогией.
//======
Попробую пояснить, хотя это довольно муторно...
Вообще-то вопрос этот из серии "если кит - и вдруг на слона - кто кого сборет?"
Глагол "хотеть" может управлять и родительным, и винительным падежом.
Давайте разберемся сначала с единственным числом.
Для одушевленных существительных падежи совпадают: *"Ты хочешь щенка?"* - и никаких вопросов не порождают.
Для неодушевленного уже сложнее. Глагол "хотеть", возможно как раз под влиянием формы для одушевленных объектов, опционально изменил управление с винительного на родительный - оставаясь при этом глаголом переходным. Первая тенденция требует одной формы, второй факт - другой. "*Ты хочешь ножик?*" - *"Ты хочешь **о**рдена?"*. Между этими двумя случаями есть небольшая смысловая разница, грамматисты её прекрасно знают, я здесь полный разбор опускаю, ограничусь частным указанием, что первое тут означает конкретное реальное желание, второе - отдаленное, абстрактное или несбыточное. Но это не строго.
Множественное число в принципе работает по тем же правилам, но в силу традиции частота родительного падежа сильно перевешивает. В тех же контекстах *"Ты хочешь ножиков"* будет употребляться чаще, чем *"ты хочешь ножики?"*. Возможно потому, что категория конкретности у множественного числа заметно ниже, чем у единственного. Тем не менее винительный падеж все еще вполне возможен, особенно в тех случаях, когда множественное число имеет смысловой (не грамматический!) оттенок собирательности: *"Ты хочешь помидоры?"* и *"Ты хочешь помидоров?"* равноправны. А смысловое различие идет уже не по линии "конкретное"-"абстрактное", а по разделу "общее-частное".
Перейдем к грибам. Тоже издали.
*"Ты хочешь (жареные) подосиновики, подберезовики, шампиньоны, маслята?"* - никаких проблем. Как блюдо, кушанье... Шампиньоны, вроде, не жарят, но с грамматикой все в порядке.
*"Ты хочешь (жареных) подосиновиков, шампиньонов, подберезовиков, маслят?"* - тем более все ОК. Особенно, если речь идет о небольшой порции.
С "лисичками" хуже. Лисичка - слово грамматически одушевленное. Поэтому форма "лисичек" преобладает, хотя и *"хочешь лисички?"* вполне возможна.
Что ж такого происходит с опятами-опенками, что заставляет большинство носителей языка говорить именно *"Хочешь опят?"* вопреки всем вышевысказанным грамматическим соображениям?
Попробуем разобраться. Как было показано, сами по себе соображения о падеже и/или одушевленности ничего не определяют. Но, как совершенно верно заметила Екатерина, "опята" - это форма особая. Исторически "опята" было неправильным, слово "опенок" не имеет суффикса "-енок-": "-ен-" - от "пня", корень - "пен". Это абсолютно препятствовало образованию формы "опята", нормативным считалось "опенки" - и этим они отличались от "маслят". Поэтому *"хочешь опенки?"* (В.п) вполне успешно конкурировало с *"хочешь опенков"* (Р.п.)- и, видимо, даже преобладало.
Но дальше под влиянием *"масленок"-"маслята"* и т.п. де-факто произошло переразложение слова *"опенок"*, *"-енок-"* стало восприниматься как суффикс, порождающий во множественном числе новую форму "опята". И вот для этой-то новой формы, для которой соверешенно отсутствовала грамматическая традиция разделения родительного и винительного падежей, равно как само ощущение её неодушевленности, появилось закрепленное простой использования *"хочешь опят"* - как субъективно единственная возможная форма в обоих падежах и всех значениях. Но грамматически более правильную *"Хочешь опята?"* для винительного падежа (равно как и саму возможность использования винительного падежа для неодушевленных существительных) никто не отменял. Поэтому *"Ты хочешь опята?"* никак нельзя лишать прав на нормативность.
И в заключение. Разговоры про форму винительного падежа для всякой снеди редко проходят мимо ставшей знаменитой у филологов фразы "А я так люблю крабы" из "Иронии судьбы".
Так вот, будьте уверены, герой Мягкова сказал все правильно. Во всяком случае - с точки зрения грамматики.

//======
Попробую пояснить, хотя это довольно муторно...
Вообще-то вопрос этот из серии "если кит - и вдруг на слона - кто кого сборет?"
Глагол "хотеть" может управлять и родительным, и винительным падежом.
Давайте разберемся сначала с единственным числом.
Для одушевленных существительных падежи совпадают: *"Ты хочешь щенка?"* - и никаких вопросов не порождают.
Для неодушевленного уже сложнее. Глагол "хотеть", возможно как раз под влиянием формы для одушевленных объектов, опционально изменил управление с винительного на родительный - оставаясь при этом глаголом переходным. Первая тенденция требует одной формы, второй факт - другой. "*Ты хочешь ножик?*" - *"Ты хочешь **о**рдена?"*. Между этими двумя случаями есть небольшая смысловая разница, грамматисты её прекрасно знают, я здесь полный разбор опускаю, ограничусь частным указанием, что первое тут означает конкретное реальное желание, второе - отдаленное, абстрактное или несбыточное. Но это не строго.
Множественное число в принципе работает по тем же правилам, но в силу традиции частота родительного падежа сильно перевешивает. В тех же контекстах *"Ты хочешь ножиков"* будет употребляться чаще, чем *"ты хочешь ножики?"*. Возможно потому, что категория конкретности у множественного числа заметно ниже, чем у единственного. Тем не менее винительный падеж все еще вполне возможен, особенно в тех случаях, когда множественное число имеет смысловой (не грамматический!) оттенок собирательности: *"Ты хочешь помидоры?"* и *"Ты хочешь помидоров?"* равноправны. А смысловое различие идет уже не по линии "конкретное"-"абстрактное", а по разделу "общее-частное".
Перейдем к грибам. Тоже издали.
*"Ты хочешь (жареные) подосиновики, подберезовики, шампиньоны, маслята?"* - никаких проблем. Как блюдо, кушанье... Шампиньоны, вроде, не жарят, но с грамматикой все в порядке.
*"Ты хочешь (жареных) подосиновиков, шампиньонов, подберезовиков, маслят?"* - тем более все ОК. Особенно, если речь идет о небольшой порции.
С "лисичками" хуже. Лисичка - слово грамматически одушевленное. Поэтому форма "лисичек" преобладает, хотя и *"хочешь лисички?"* вполне возможна.
Что ж такого происходит с опятами-опенками, что заставляет большинство носителей языка говорить именно *"Хочешь опят?"* вопреки всем вышевысказанным грамматическим соображениям?

It's the same as using the [CDATA](http://en.wikipedia.org/wiki/CDATA) technique on the `<script>` tag... to **protect bad parsing of the data** from really weird engines (mainly IE) :)
though the **correct way** would be using:
for styles
==========
```
<style type="text/css">
/*<![CDATA[*/
body { color: yellow; }
/*]]>*/
</style>
```
for scripts

```
<script type="text/javascript">
//<![CDATA[
$(function() { ... });

using `CDATA` in both cases is the **correct and safe way**, the *comment* way it's just a trick to accomplish the same end result.

] | Well... as I was typing the tags for my question, it appeared that stack overflow already had defined the terms in the tags description. Here their definitions which I found very good:
>
> **[Remote debugging](https://stackoverflow.com/tags/remote-debugging/info)** is the process of running a debug session in a local development environment attached to a remotely deployed application.
>
>
> **[Profiling](https://stackoverflow.com/tags/profiling/info)** is the process of measuring an application or system by running an analysis tool called a profiler. Profiling tools can focus on many aspects: functions call times and count, memory usage, cpu load, and resource usage.
>
>
> **[Tracing](https://stackoverflow.com/tags/tracing/info)** is a specialized use of logging to record information about a program's execution.
>
>
> | In addition to the answer from Samuel:
1. **Debugging** is the process of looking for bugs and their cause in applications. a bug can be an error or just some unexpected behaviour (e.g. a user complains that he/she receives an error when he/she uses an invalid date format). typically a debugger is used that can pause the execution of an application, examine variables and manipulate them.
2. **Profiling** is a dynamic analysis process that collects information about the execution of an application. the type of information that is collected depends on your use case, e.g. the number of requests. the result of profiling is a profile with the collected information. the source for a profile can be exact events (see tracing below) or a sample of events that occured.
because the data is aggregated in a profile it is irrelevant when and in which order the events happened.
3. **Tracing** "trace is a log of events within to the program"(Whitham). those events can be ordered chronologically. thats why they often contain a timestamp. Tracing is the process of generating and collecting those events. the use case is typically flow analysis.
example tracing vs profiling:
```
Trace:
[2021-06-12T11:22:09.815479Z] [INFO] [Thread-1] Request started
[2021-06-12T11:22:09.935612Z] [INFO] [Thread-1] Request finished
[2021-06-12T11:22:59.344566Z] [INFO] [Thread-1] Request started
[2021-06-12T11:22:59.425697Z] [INFO] [Thread-1] Request finished
Profile:
2 "Request finished" Events
2 "Request started" Events
```
so if tracing and profiling measure the same events you can construct a profile from a trace but not the other way around.

Answer:
synchronized requires an object on which lock is attained before entering the synchronized block or method.
In this case lock is being attained on the objects on which the method is executed hence thread 1 is locking on object th1, thread 2 is locking on th2 and so on.
therefore, all the threads are locking onto different objects and are allowed to run simultaneously.

55,123,258 | I have Grafana and postgres installed and connected. I use grafana to display charts of data I add to postgres. My postgres database has a table with records from multiple sources. The schema looks like this:

] | I think you may be having an issue with trying to get the value of the Title tag because you're trying to grab the first attribute of every XML element but the only element that has an attribute is `ArrayOfInternship`.
There are a couple of ways that you could extract all of the titles from all Internship elements in the array.
First would be looping and uses the `XmlDocument` class like what your code uses
```
XmlDocument doc = new XmlDocument();
doc.Load(@"InternList.xml");
// Loop over child nodes of <ArrayOfInternship>...
foreach (XmlNode node in doc.DocumentElement)
{
// Loop over the child nodes of the <Internship> nodes
foreach (XmlNode child in node.ChildNodes)
{
if (child.Name.Equals("Title", StringComparison.OrdinalIgnoreCase))
{
lstBxListIntern.Items.Add(child.InnerText);
}
}
}
```
The second solution that I came up with and personally like better because it's more succinct. You probably want to utilize the above solution since you are a beginner and it will most likely be easier for you to read. But here's the other solution using LINQ to XML.
```
XElement xml = XElement.Load(@"InternList.xml");
var titles = xml.Descendants("Title")
.Select(x => x.Value)
.ToList();
lstBxListIntern.Items.AddRange(titles);
```
Let me know if you need any clarification on what I mentioned and I'll be happy to clarify. | One possible solution
```
XmlDocument xmldocIntern = new XmlDocument();
xmldocIntern.Load(@"InternList.xml");
var oc = new ListBox.ObjectCollection(lstBxListIntern, xmldocIntern.DocumentElement.GetElementsByTagName("Title").Cast<XmlNode>().Select(node => node.InnerText).ToArray());

```

At first we need to connect to database…
File Name: connection.php
```
<?php
$db = mysql_connect("Database", "username", "password") or die("Could not connect.");
if(!$db)
die("no db");
if(!mysql_select_db("Databasename",$db))

] | You cannot use `-replace` and massage the data at the time of the substitution. Your replacement was failing as the string literal `$1` cannot be converted to integer. As discussed in a similar question: [Passing a function to Powershell's (replace) function](https://stackoverflow.com/questions/8163061/passing-a-function-to-powershells-replace-function) you can use a scriptblock and the .nNet regex static method `Replace`.
```
$replaceBlock = {
# Groups 0 contains the whole match. 1 is the first group... and so on.
([convert]::ToInt32($args[0].Groups[1],10) + 12).ToString("00000") + $args[0].Groups[2]
}
Get-ChildItem | Where-Object{$_.name -match '^\d{5}_.+'} | Rename-Item -NewName {
[Regex]::Replace($_.name, '^(\d{5})(_.+)', $replaceBlock)
} -whatif
```
You can use the script block inline but getting it out makes for a little cleaner code. However I would likely use `-match` and the returned `$matches` object to do the same thing.
```
Get-ChildItem | Where-Object{$_.name -match '^(\d{5})(_.+)'} | Rename-Item -NewName {
([int]$Matches[1] + 12).ToString("00000") + $Matches[2]
} -whatif
```
Note that I updated the `where-object` to have capture groups. | Haha, I got an answer.
```
dir * | ?{$_.name -match '^\d{5}_.+'} | Rename-Item -NewName {(([convert]::toint32($_.name.substring(0, 5), 10) + 12).ToString("00000")) + $_.name.substring(5)} -whatif
```
Just found that I can use any code in the `-newname{}` block. But I still don't understand why my `-replace` way did not work. |

Richard McClintock, a Latin professor at Hampden-Sydney College in Virginia, looked up one of the more obscure Latin words, consectetur, from a Lorem Ipsum passage, and going through the cites of the word in classical literature, discovered the undoubtable source. Lorem Ipsum comes from sections 1.10.32 and 1.10.33 of "de Finibus Bonorum et Malorum" (The Extremes of Good and Evil) by Cicero, written in 45 BC. This book is a treatise on the theory of ethics, very popular during the Renaissance. The first line of Lorem Ipsum, "Lorem ipsum dolor sit amet..", comes from a line in section 1.10.32.Contrary to popular belief, Lorem Ipsum is not simply random text.

Uses box-sizing:border-box, padding and negative margin. Assumes, as in the OP, that the image is fixed to 200px wide, which means with a 5px border, you add the actual width you want it since border-box includes the borders and padding. Regarding the gap below it on the other screen shot, if you change your paragraph line-height to 24px, it won't be there or you can manipulate the image height. Google vertical rhythm and images.
```
.modal .img {
width:210px;
height:230px;
border:5px solid #f3f3f3;
margin:18px -220px 0 0;
box-sizing:border-box;
float:left;
}
.modal p{
box-sizing:border-box;
font-size: 16px;
text-align:left;
line-height:25px;
float:left;
padding:0 10px 0 230px;
}
``` | You could wrap the paragraph in a div tag:
```
<img src="http://www.peacethroughpie.org/wp-content/uploads/2013/09/baked-pie.jpg">
<div><p> ... </p></div>
```
Then you could set the div to a width of 100% - width of image and float it to the right.
```
img {
float: left;
width: 20%;
}
div {
display: block;
width: 80%;
float: right;
}
```

But Im not having this, Im having my text to go left when it exceeds the image height, as you see in my image.
And also, I'm having a blank space, marked by the circle in my picture below, and I'm not understand why.
