Parsing json directly using input stream | <p>I am doing a api call and in response i am getting json. So for that I want to parse it directly through input stream so that there would not be need of storing it in memory.
For this I am trying to use JSONReader but that i am unable use for api's less than 11.
So i dont know how to proceed with. I want it to be done from 2.0 version onwards. Even parsing through JsonReader is not working.
I was thing of having GSON parser but i am not getting how to implement the same with Inputstream.</p>
<p>EDIT:
My code for the same:</p>
<pre><code>HttpClient client = new DefaultHttpClient();
HttpGet httpGet = new HttpGet(url);
try {
HttpResponse response = client.execute(httpGet);
StatusLine statusLine = response.getStatusLine();
int statusCode = statusLine.getStatusCode();
Log.e("123", "Status code ----------- "+statusCode);
if (statusCode == 200) {
HttpEntity entity = response.getEntity();
InputStream content = entity.getContent();
// for showing it on textview i am storing in in builder
BufferedReader bReader = new BufferedReader(new InputStreamReader(content));
String line;
while ((line = bReader.readLine()) != null) {
builder.append(line);
}
////////////
JsonReader reader = new JsonReader(new InputStreamReader(content));
reader.setLenient(true);
readGson(reader);
} else {
Log.e("TAG", "Failed to download file");
}
} catch (ClientProtocolException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
return builder.toString();
}
private void readGson(JsonReader reader) {
// TODO Auto-generated method stub
Log.e("TAG", "inidde readgson"+reader);
try {
Log.e("TAG", "inside try");
reader.beginObject();
Log.e("123", "inside try ");
while(reader.hasNext()){
Log.e("TAG", "reader values"+reader);
String name = reader.nextName();
if (name.equals("max_id")) {
long max_id = reader.nextLong();
Log.e("TAG", "sdbfhsajfgsdjbgksdfjv------------------"+max_id);
} else {
Log.e("TAG", "c skfnvklsfvn skip value");
reader.skipValue();

Gradle: Project "x" not found in root project "myProject" | <p>Having upgraded to Android Studio from Eclipse I wanted to update my TouchDB library which is now <a href="https://github.com/couchbase/couchbase-lite-android" rel="nofollow">Coubasebase-lite-android</a>.

How do you dynamically create an AWS IAM policy document with a variable number of resource blocks using terraform? | <p>In my current terraform configuration I am using a static JSON file and importing into terraform using the file function to create an AWS IAM policy.</p>
<p>Terraform code:</p>

policy = "${file("policy.json")}"
}

<p>My goal is to use a list of account numbers stored in a terraform variable and use that to dynamically build the aws_iam_policy resource in terraform. My first idea was to try and use the terraform jsonencode function. However, it looks like there might be a way to implement this using the new terraform dynamic expressions foreach loop.</p>
<p>The sticking point seems to be appending a variable number of resource blocks in the IAM policy. </p>

<pre><code>var account_number_list = ["123","456","789"]
policy = {"Statement":[]}
for each account_number in account_number_list:
policy["Statement"].append(policy block with account_number var reference)

Running multiple async queries with ADODB - callbacks not always firing | <p>I have an Excel workbook that fires three queries to a database to populate three tables on hidden sheets, and then runs three 'refresh' scripts to pull this data through to three visible presentation sheets (one per query). Running this synchronously is quite slow: The total time to refresh is the sum of the time of each of the three queries, plus the sum of the time for each 'refresh' script to run.</p>
<p>I'm aware that VBA isn't multi-threaded, but I thought it would be possible to speed things up a bit by firing the queries off asynchronously (thus allowing some clean-up work to be done whilst they were executing), and then doing the population / refresh work for each sheet as the data comes back.</p>
<p>I rewrote my script as follows (note that I've had to remove the connection strings, query strings etc and make the variables generic):</p>
<pre><code>Private WithEvents cnA As ADODB.Connection
Private WithEvents cnB As ADODB.Connection
Private WithEvents cnC As ADODB.Connection
Private Sub StartingPoint()
'For brevity, only listing set-up of cnA here. You can assume identical
'set-up for cnB and cnC
Set cnA = New ADODB.Connection
Dim connectionString As String: connectionString = "<my conn string>"
cnA.connectionString = connectionString
Debug.Print "Firing cnA query: " & Now
cnA.Open
cnA.Execute "<select query>", adAsyncExecute 'takes roughly 5 seconds to execute
Debug.Print "Firing cnB query: " & Now
cnB.Open
cnB.Execute "<select query>", adAsyncExecute 'takes roughly 10 seconds to execute
Debug.Print "Firing cnC query: " & Now
cnC.Open
cnC.Execute "<select query>", adAsyncExecute 'takes roughly 20 seconds to execute
Debug.Print "Clearing workbook tables: " & Now
ClearAllTables
TablesCleared = True
Debug.Print "Tables cleared: " & Now
End Sub
Private Sub cnA_ExecuteComplete(ByVal RecordsAffected As Long, ...)
Debug.Print "cnA records received: " & Now
'Code to handle the recordset, refresh the relevant presentation sheet here,
'takes roughly < 1 seconds to complete
Debug.Print "Sheet1 tables received: " & Now
End Sub
Private Sub cnB_ExecuteComplete(ByVal RecordsAffected As Long, ...)
Debug.Print "cnB records received: " & Now
'Code to handle the recordset, refresh the relevant presentation sheet here,
'takes roughly 2-3 seconds to complete
Debug.Print "Sheet2 tables received: " & Now
End Sub
Private Sub cnC_ExecuteComplete(ByVal RecordsAffected As Long, ...)
Debug.Print "cnC records received: " & Now
'Code to handle the recordset, refresh the relevant presentation sheet here,
'takes roughly 5-7 seconds to complete
Debug.Print "Sheet3 tables received: " & Now
End Sub
</code></pre>
<p>Typical expected debugger output:</p>
<pre><code>Firing cnA query: 21/02/2014 10:34:22
Firing cnB query: 21/02/2014 10:34:22
Firing cnC query: 21/02/2014 10:34:22
Clearing tables: 21/02/2014 10:34:22
Tables cleared: 21/02/2014 10:34:22
cnB records received: 21/02/2014 10:34:26
Sheet2 tables refreshed: 21/02/2014 10:34:27
cnA records received: 21/02/2014 10:34:28
Sheet1 tables refreshed: 21/02/2014 10:34:28
cnC records received: 21/02/2014 10:34:34
Sheet3 tables refreshed: 21/02/2014 10:34:40
</code></pre>
<p>The three queries can come back in different orders depending on which finishes first, of course, so sometimes the typical output is ordered differently - this is expected.</p>
<p>Sometimes however, one or two of the <code>cnX_ExecuteComplete</code> callbacks don't fire at all. After some time debugging, I'm fairly certain the reason for this is that if a recordset returns whilst one of the callbacks is currently executing, the call does not occur. For example:</p>
<ul>
<li>query A, B and C all fire at time 0</li>
<li>query A completes first at time 3, <code>cnA_ExecuteComplete</code> fires</li>
<li>query B completes second at time 5</li>
<li><code>cnA_ExecuteComplete</code> is still running, so <code>cnB_ExecuteComplete</code> never fires</li>
<li><code>cnA_ExecuteComplete</code> completes at time 8</li>
<li>query C completes at time 10, <code>cnC_ExecuteComplete</code> fires</li>
<li>query C completes at time 15</li>
</ul>
<p>Am I right in my theory that this is the issue? If so, is it possible to work around this, or get the call to 'wait' until current code has executed rather than just disappearing?</p>
<p>One solution would be to do something extremely quick during the <code>cnX_ExecuteComplete</code> callbacks (eg, a one-liner <code>Set sheet1RS = pRecordset</code> and a check to see if they're all done yet before running the refresh scripts synchronously) so the chance of them overlapping is about zero, but want to know if there's a better solution first.</p> | 0 | 1,532 |

Stratified sampling with Random Forests in R | <p>I read the following in the documentation of <code>randomForest</code>:</p>
<blockquote>
<p>strata: A (factor) variable that is used for stratified sampling.</p>
<p>sampsize: Size(s) of sample to draw. For classification, if sampsize
is a vector of the length the number of strata, then sampling
is stratified by strata, and the elements of sampsize
indicate the numbers to be drawn from the strata.</p>
</blockquote>
<p>For reference, the interface to the function is given by:</p>
<pre><code> randomForest(x, y=NULL, xtest=NULL, ytest=NULL, ntree=500,
mtry=if (!is.null(y) && !is.factor(y))
max(floor(ncol(x)/3), 1) else floor(sqrt(ncol(x))),
replace=TRUE, classwt=NULL, cutoff, strata,
sampsize = if (replace) nrow(x) else ceiling(.632*nrow(x)),
nodesize = if (!is.null(y) && !is.factor(y)) 5 else 1,
maxnodes = NULL,
importance=FALSE, localImp=FALSE, nPerm=1,
proximity, oob.prox=proximity,
norm.votes=TRUE, do.trace=FALSE,
keep.forest=!is.null(y) && is.null(xtest), corr.bias=FALSE,
keep.inbag=FALSE, ...)
</code></pre>
<p>My question is: How exactly would one use <code>strata</code> and <code>sampsize</code>? Here is a minimal working example where I would like to test these parameters:</p>
<pre><code>library(randomForest)
iris = read.table("http://archive.ics.uci.edu/ml/machine-learning-databases/iris/iris.data", sep = ",", header = FALSE)
names(iris) = c("sepal.length", "sepal.width", "petal.length", "petal.width", "iris.type")
model = randomForest(iris.type ~ sepal.length + sepal.width, data = iris)
> model
500 samples
6 predictors
2 classes: 'Y0', 'Y1'
No pre-processing
Resampling: Bootstrap (7 reps)
Summary of sample sizes: 477, 477, 477, 477, 477, 477, ...
Resampling results across tuning parameters:
mtry ROC Sens Spec ROC SD Sens SD Spec SD
2 0.763 1 0 0.156 0 0
4 0.782 1 0 0.231 0 0
6 0.847 1 0 0.173 0 0
ROC was used to select the optimal model using the largest value.
The final value used for the model was mtry = 6.
</code></pre>
<p>I come to these parameters since I would like RF to use bootstrap samples that respect the proportion of positives to negatives in my data.</p>
<p><a href="https://stackoverflow.com/questions/8704681/random-forest-with-classes-that-are-very-unbalanced">This other thread</a>, started a discussion on the topic, but it was settled without clarifying how one would use these parameters.</p> | 0 | 1,131 |
how to drag and drop files from a directory in java | <p>I want to implement dragging and dropping of files from a directory such as someones hard drive but can't figure out how to do it. I've read the java api but it talks of color pickers and dragging and dropping between lists but how to drag files from a computers file system and drop into my application. I tried writing the transferhandler class and a mouse event for when the drag starts but nothing seems to work. Now I'm back to just having my JFileChooser set so drag has been enabled but how to drop? </p>

This in turn will create a new object for the <code>ViewHolder</code> class in which I "TRY" to bind the elements inside my xml depending on the <code>viewType</code>.

jQuery Validation plugin: submitHandler not preventing default on submit when making ajax call to servlet - return false not working | <p>I have a simple form that uses jquery and a servlet. The jquery makes an ajax call to the servlet, the servlet makes some server side calculations, then displays the results on the same page via jQuery. I don't want the form to do a default submit (and go to the servlet) because I want to stay on the same page and display results dynamically. It works exactly how I want it to as is:</p>
<p>HTML:</p>
<pre><code><form name="form1" action="FormHandler1" method="POST" class="stats-form">
<input class="stats-input" id="number0" type="text" name="number0">
<input id="number1" type="text" name="number1">
<input id="number2" type="text" name="number2">
<input id="number3" type="text" name="number3">
<input type="submit" value="Calculate" class="calculate-stats" name="stats-submit">
</form>
</code></pre>
<p>jQuery:</p>
<pre><code>form.submit (function(event) {
$.ajax({
type: form.attr("method"), // use method specified in form attributes
url: form.attr("action"), // use action specified in form attributes (servlet)
data: form.serialize(), // encodes set of form elements as string for submission
success: function(data) {
// get response form servlet and display on page via jquery
}
});
event.preventDefault(); // stop form from redirecting to java servlet page
});
</code></pre>
<p>Now, I wanted to add form validation, since the servlet expects decimal numbers to do it's calculations. The user should only be allowed to enter numbers, no other characters. To do this I adopted the popular <a href="http://jqueryvalidation.org/" rel="nofollow">jQuery Validation</a> plugin. </p>
<p>The validation works as expected, but to make my ajax call to the servlet I have to use the submitHandler jQuery Validation provides, instead of the jQuery submit method shown above. When I use the validation submitHandler, the default action of the form on submit is executed, going to the servlet page instead of staying on the same page to display my results dynamically in jQuery. I have to pass the formHandler a form, instead of an event like before, which allowed me to prevent the default action. The only option is to return false, but it doesn't work. I've been trying to figure this out for the past two days, and have pretty much exhausted my google-fu. Here is the new code giving me grief:</p>
<pre><code>form.validate({
rules: {
number0: ruleSet,
number1: ruleSet,
number2: ruleSet,
number3: ruleSet,
},
submitHandler: function (form) {
$.ajax({
type: "POST",
url: form.attr("action"),
data: form.serialize(),
success: function () {
// get response from servlet and display on page via jQuery
}
});
return false; // required to block normal submit ajax used
}
});
</code></pre>
<p>Any help would be appreciated, I'd like to use this neat jQuery form validation, but I may just write my own jQuery validation from scratch so that I can use the form submit method that I already have working.</p> | 0 | 1,155 |

The entity or complex type ... cannot be constructed in a LINQ to Entities query | <p>Why does one method work but not the other, when it seems they are both doing the same thing, i.e. constructing an entity. My question then, is there a way to construct the entity in a L2E query instead of having to use just Linq or indeed both?</p>
<p>This works fine...</p>
<pre><code>var queryToList = (from ac in ctx.AuthorisationChecks
where wedNumbers.Contains(ac.WedNo)
orderby ac.WedNo, ac.ExpAuthDate, ac.ActAuthDate
select new AuthorisationCheck
{
Blah = ac.Blah
}).ToList();
model.AuthorisationChecks = queryToList.Select(x => new AuthorisationCheck
{
Blah = x.Blah
}).ToList();
</code></pre>
<p>However, if i change...</p>
<pre><code>var queryToList
</code></pre>
<p>to</p>
<pre><code>model.AuthorisationChecks queryToList // Of type List<AuthorisationCheck>
</code></pre>
<p>i get the error in the Title...</p>
<pre><code>The entity or complex type 'Model.AuthorisationCheck' cannot be constructed in a LINQ to Entities query.
</code></pre>
<p><strong>EDIT:</strong>
In the model it is simply, nothing fancy here.</p>
<pre><code>public List<AuthorisationCheck> AuthorisationChecks { get; set; }
</code></pre>
<p><strong>EDIT2:</strong>
Tidied this up a little to be (which works fine)...</p>
<pre><code>model.AuthorisationChecks = (from ac in ctx.AuthorisationChecks
where wedNumbers.Contains(ac.WedNo)
orderby ac.WedNo, ac.ExpAuthDate, ac.ActAuthDate
select ac).ToList()
.Select(x => new AuthorisationCheck
{
Blah = x.Blah
}).ToList();
</code></pre>
<p><strong>EDIT2: My Solution</strong>
I wasn't happy with the anonymous type method and so went ahead and created a simple model containing only the properties I required to be used in the viewmodel.</p>
<p>Changed the type of model.AuthorisationChecks</p>
<p>from </p>
<pre><code>List<AuthorisationCheck> // List of Entities
</code></pre>
<p>to</p>
<pre><code>List<AuthorisationCheckModel> // List of models
</code></pre>
<p>which allows the following code to work, and without profiling it seems a lot quicker than using an anonymous type (and of course I don't cast to a list twice!).</p>
<pre><code>model.AuthorisationChecks = (from ac in ctx.AuthorisationChecks
where wedNumbers.Contains(ac.WedNo)
orderby ac.WedNo, ac.ExpAuthDate, ac.ActAuthDate
select new AuthorisationCheckModel
{
Blah = x.Blah
}).ToList();
</code></pre>
<p>P.S. I was once warned by a coworker (who used to work for Microsoft) that it isn't a good idea to directly use Entities in this manner, maybe this was one of the reasons he was thinking of, I've also noticed some odd behavior using Entities directly in other cases (mainly corruptions).</p> | 0 | 1,379 |

Which .NET collection is faster: enumerating foreach Dictionary<>.Values or List<>? | <p>Are one of these enumerations faster than the other or about the same? (example in C#)</p>
<p>Case 1:</p>
<pre><code>Dictionary<string, object> valuesDict;
// valuesDict loaded with thousands of objects
foreach (object value in valuesDict.Values) { /* process */ }
</code></pre>
<p>Case 2:</p>
<pre><code>List<object> valuesList;
// valuesList loaded with thousands of objects
foreach (object value in valuesList) { /* process */ }

<p>UPDATE:</p>
<p>Background:</p>
<p>The dictionary would be beneficial for keyed search elsewhere (as opposed to iterating through a list), but the benefit would be diminished if iterating through the dictionary is much slower than going through the list.</p>

Taking the advice of many, I've done my own testing.</p>
<p>First, these are the results. Following is the program.</p>

How to set linker flags for OpenMP in CMake's try_compile function | <p>I would like to verify that the current compiler can build with openmp support. The application has do deploy across a wide variety of unix systems, some of which might have old versions of OpenMP, and I would like to test for important OpenMP functionality. So, I want to build a test source file that incorporates some of the OpenMP calls.</p>
<p>Thus, I created a very simple test file, and attempted to use the try_compile function from CMake. Ufortunately, it doesn't seem to apply the -fopenmp linker flag correctly. Does anyone know how to either force the linker flag or to see if the linker flag is being applied anywhere?</p>
<p>from CMakeLists.txt</p>
<pre><code>try_compile(
HAVE_OPENMP
${APBS_ROOT}/src/config
${APBS_ROOT}/src/config/omp_test.c
CMAKE_FLAGS "-DCMAKE_C_FLAGS=-fopenmp -DCMAKE_EXE_LINKER_FLAGS=-fopenmp"
OUTPUT_VARIABLE TRY_COMPILE_OUTPUT
)
</code></pre>
<p>from omp_test.c</p>
<pre><code>#include <stdio.h>
#include <omp.h>
int main()
{
int i;
int threadID = 0;
#pragma omp parallel for private(i, threadID)
for(i = 0; i < 16; i++ )
{
threadID = omp_get_thread_num();
#pragma omp critical
{
printf("Thread %d reporting\n", threadID);
}
}
return 0;
}

<p>The resulting output is</p>

Codeigniter Pagination From Database limit, offset | <p>I started a web application in CI 3.0, everything working smooth, I got my pagination working, but there is a problem wich I cannot figure out...</p>
<p>For example, I have the following URL: <strong>localhost/statistics/api_based</strong>
When navigate, $query results are displayed, links are generated, OK.
But, when I navigate to <strong>page 2</strong> for example, the URL will become:
<strong>localhost/statistics/dll_based/index/2</strong> and <strong>page 3</strong> will become <strong>localhost/statistics/api_based/index/3</strong> , so therefore I am using segments.
Now the problem is the query that is generated:</p>
<pre><code>SELECT * FROM `shield_api` ORDER BY `id` ASC limit 20 offset 2
</code></pre>
<p><strong>offset 2</strong> - is the page number 2, and it should be 20, if I am correct.
I am displaying 20 results per page, so first page is correctly showing results from 1 - 20, but then page 2 will display results from 2 - 21, so you get my point, it`s not OK...</p>
<p>Here is my controller:</p>
<pre><code>function index($offset = 0) {
// Enable SSL?
maintain_ssl ( $this->config->item ( "ssl_enabled" ) );
// Redirect unauthenticated users to signin page
if (! $this->authentication->is_signed_in ()) {
redirect ( 'account/sign_in/?continue=' . urlencode ( base_url () . 'statistics/api_based' ) );
}
if ($this->authentication->is_signed_in ()) {
$data ['account'] = $this->account_model->get_by_id ( $this->session->userdata ( 'account_id' ) );
}
$per_page = 20;
$qry = "SELECT * FROM `shield_api` ORDER BY `id` ASC";
//$offset = ($this->uri->segment ( 4 ) != '' ? $this->uri->segment ( 4 ) : 0);
$config ['total_rows'] = $this->db->query ( $qry )->num_rows ();
$config ['per_page'] = $per_page;
$config ['uri_segment'] = 4;
$config ['base_url'] = base_url () . '/statistics/api_based/index';
$config ['use_page_numbers'] = TRUE;
$config ['page_query_string'] = FALSE;

$config ['num_tag_open'] = '<li>';
$config ['num_tag_close'] = '</li>';
$config ["num_links"] = round ( $config ["total_rows"] / $config ["per_page"] );
$this->pagination->initialize ( $config );
$data ['pagination_links'] = $this->pagination->create_links ();
//$data ['per_page'] = $this->uri->segment ( 4 );
$data ['offset'] = $offset;
$qry .= " limit {$per_page} offset {$offset} ";
if ($data ['pagination_links'] != '') {
$data ['pagermessage'] = 'Showing ' . ((($this->pagination->cur_page - 1) * $this->pagination->per_page) + 1) . ' to ' . ($this->pagination->cur_page * $this->pagination->per_page) . ' results, of ' . $this->pagination->total_rows;
}
$data ['result'] = $this->db->query ( $qry )->result_array ();

How Should VSCode Be Configured To Support A Lerna Monorepo? | <p>I have a <a href="https://github.com/lerna/lerna" rel="noreferrer">lerna</a> monorepo containing lots of packages.</p>
<p>I'm trying to achieve the following:</p>
<ol>
<li>Ensure that VSCode provides the correct import suggestions (based on package names, not on relative paths) from one package to another.</li>
<li>Ensure that I can 'Open Definition' of one of these imports and be taken to the src of that file.</li>
</ol>
<p>For 1. I mean that if I am navigating code within package-a and I start to type a function exported by package-b, I get a suggestion that will trigger the adding of an import: `import { example } from 'package-b'.</p>
<p>For 2. I mean that if I alt/click on the name of a function exported by 'package-b' while navigating the file from a different package that has imported it, I am taken to '/packages/namespace/package/b/src/file-that-contains-function.js',</p>
<p>My (lerna) monorepo is structured as standard, for example here is a 'components' package that is published as <code>@namespace/components</code>.</p>
<pre><code>- packages
- components
- package.json
- node_modules
- src
- index.js
- components
- Button
- index.js
- Button.js
- es
- index.js
- components
- Button
- index.js
- Button.js
</code></pre>
<p>Note that each component is represented by a directory so that it can contain other components if necessary. In this example, <code>packages/components/index</code> exports <code>Button</code> as a named export. Files are transpiled to the package's <code>/es/</code> directory.</p>
<p>By default, VSCode provides autosuggestions for imports, but it is confused by this structure and, for if a different package in the monorepo needs to use <code>Button</code> for example, will autosuggest all of the following import paths:</p>
<ul>
<li><code>packages/components/src/index.js</code></li>
<li><code>packages/components/src/Button/index.js</code></li>
<li><code>packages/components/src/Button/Button.js</code></li>
<li><code>packages/components/es/index.js</code></li>
<li><code>packages/components/es/Button/index.js</code></li>
<li><code>packages/components/es/Button/Button.js</code></li>
</ul>
<p>However none of these are the appropriate, because they will be rendered as relative paths from the importing file to the imported file. In this case, the following import is the correct import:</p>
<pre><code>import { Button } from '@namespace/components'
</code></pre>
<p>Adding excludes to the project's <code>jsconfig.json</code> has no effect on the suggested paths, and doesn't even remove the suggestions at <code>/es/*</code>:</p>
<pre><code>{
"compilerOptions": {
"target": "es6",
},
"exclude": [
"**/dist/*",
"**/coverage/*",
"**/lib/*",
"**/public/*",
"**/es/*"
]
}
</code></pre>
<p>Explicitly adding paths using the "compilerOptions" also fails to set up the correct relationship between the files:</p>
<pre><code>{
"compilerOptions": {
"target": "es6",
"baseUrl": ".",
"paths": {
"@namespace/components/*": [
"./packages/namespace-components/src/*.js"
]
}
},
}
</code></pre>
<p>At present Cmd/Clicking on an import from a different package fails to open anything (no definition is found).</p>
<p><strong>How should I configure VSCode so that:</strong></p>
<ol>
<li><strong>VSCode autosuggests imports from other packages in the monorepo using the namespaced package as the import value.</strong></li>
<li><strong>Using 'Open Definition' takes me to the src of that file.</strong></li>
</ol>

How can I dynamically name an array in Javascript? | <p>I am using jQuery and JSON to pull data from a database. Each row of the database is a different product and each product has a number of properties associated with it.</p>
<p>What I'm trying to do in js, is create a named array for each product containing all of the products properties. I know how to pull the data from JSON. I know how to construct the Array.</p>
<p>What I don't know is how to create an array name dynamically. Can someone help me out?</p>
<p>I am trying to name the array based on a field in the database. In the structure of my existing and working script, it's referenced as data.cssid. I'd like to use the value of data.cssid as the name of the array and then populate the array.</p>
<pre><code>$.getJSON("products.php",function(data){
$.each(data.products, function(i,data){
var data.cssid = new Array();
data.cssid[0] = data.productid;
...
etc
});
});
</code></pre>
<p>I know the code above is completely wrong, but it illustrates the idea. Where I declare "var data.cssid", I want to use the actual value of data.cssid as the name of the new array.</p>
<p>EDIT:</p>
<p>I've tried the methods mentioned here (except for eval). The code is below and is not really that different than my original post, except that I'm using a Object constructor.</p>
<pre><code>$(document).ready(function(){
$.getJSON("productscript.php",function(data){
$.each(data.products, function(i,data){
var arrayName = data.cssid;
obj[arrayName] = new Array();
obj[arrayName][0] = data.productid;
obj[arrayName][1] = data.productname;
obj[arrayName][2] = data.cssid;
obj[arrayName][3] = data.benefits;
alert(obj[arrayName]); //WORKS
alert(obj.shoe); //WORKS WHEN arrayName = shoe, otherwise undefined
});
});
});
</code></pre>
<p>The alert for the non-specific obj[arrayName] works and shows the arrays in all their magnificence.
But, when I try to access a specific array by name alert(obj.shoe), it works only when the arrayName = shoe. Next iteration it fails and it can't be accessed outside of this function.</p>
<p>I hope this helps clarify the problem and how to solve it. I really appreciate all of the input and am trying everything you guys suggest.</p>
<p>PROGRESS (THE SOLUTION):</p>
<pre><code>$(document).ready(function(){
$.getJSON("productscript.php",function(data){
$.each(data.products, function(i,data){
var arrayName = data.cssid;
window[arrayName] = new Array();
var arr = window[data.cssid];
arr[0] = data.productid;
arr[1] = data.productname;
arr[2] = data.cssid;
arr[3] = data.benefits;
alert(window[arrayName]); //WORKS
alert(arrayName); //WORKS
alert(shoe); //WORKS
});
});
});
function showAlert() {
alert(shoe); //WORKS when activated by button click
}
</code></pre>
<p>Thanks to everybody for your input. </p> | 0 | 1,030 |
Knockout.js mapping JSON object to Javascript Object | <p>I have a problem mapping a Json object recieved from the server into a predefined Javascript-object which contains all the necessary functions which are used in the bindings</p>
<p>Javascript code is the following</p>
<pre><code>function Person(FirstName, LastName, Friends) {
var self = this;
self.FirstName = ko.observable(FirstName);
self.LastName = ko.observable(LastName);
self.FullName = ko.computed(function () {
return self.FirstName() + ' ' + self.LastName();
})
self.Friends = ko.observableArray(Friends);
self.AddFriend = function () {
self.Friends.push(new Person('new', 'friend'));
};
self.DeleteFriend = function (friend) {
self.Friends.remove(friend);
};
}
var viewModel = new Person();
$(document).ready(function () {
$.ajax({
url: 'Home/GetPerson',
dataType: 'json',
type: 'GET',
success: function (jsonResult) {
viewModel = ko.mapping.fromJS(jsonResult);
ko.applyBindings(viewModel);
}
});
});
</code></pre>
<p>HTML:</p>
<pre><code><p>First name: <input data-bind="value: FirstName" /></p>
<p>Last name: <input data-bind="value: LastName" /></p>
<p>Full name: <span data-bind="text: FullName" /></p>
<p>#Friends: <span data-bind="text: Friends().length" /></p>
@*Allow maximum of 5 friends*@
<p><button data-bind="click: AddFriend, text:'add new friend', enable:Friends().length < 5" /></p>
<br>
@*define how friends should be rendered*@
<table data-bind="foreach: Friends">
<tr>
<td>First name: <input data-bind="value: FirstName" /></td>
<td>Last name: <input data-bind="value: LastName" /></td>
<td>Full name: <span data-bind="text: FullName" /></td>
<td><button data-bind="click: function(){ $parent.DeleteFriend($data) }, text:'delete'"/></td>
</tr>
</table>
</code></pre>
<p>My ServerSide MVC code for getting initial data looks like:</p>
<pre><code> public ActionResult GetPerson()
{
Person person = new Person{FirstName = "My", LastName="Name",
Friends = new List<Person>
{
new Person{FirstName = "Friend", LastName="Number1"},
new Person{FirstName = "Friend", LastName="Number2"}
}
};
return Json(person, JsonRequestBehavior.AllowGet);
}
</code></pre>
<p>I am trying to use the mapping plugin to load the Json into my Javascript object so everything is available for the bindings (The add-function and the computed properties on the Friend objects).</p>
<p>When I use the mapping plugin it does not seem to work.
When using the plugin the AddFriend method is not available during the binding.
Is it possible to populate the JavaScript Person object by using the mapping plugin or must everything be done manually?</p> | 0 | 1,296 |
android: Data refresh in listview after deleting from database | <p>I have an application which retrieves data from DB and displays it in a list view. I have a custom adapter for the same. So when I press the "delete" button, a delete button for each row in the list is displayed. If I press that, the particular row gets deleted in the DB and the same should be reflected in the listview also. The problem is, its not reflecting this change, I should close the app and reopen or move into some other activity and get back to see the updated results.</p>
<p>So my question is: where do I call the <code>notifyDataSetChanged()</code> method to get it updated instantly?</p>
<p>Here is my customadapter view:</p>
<pre><code>public View getView(int position, View convertView, ViewGroup parent) {
// TODO Auto-generated method stub
MenuListItems menuListItems = menuList.get(position);
if (convertView == null) {
LayoutInflater inflater = (LayoutInflater) c
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
convertView = inflater.inflate(R.layout.customlist, parent, false);
}
Button ck = (Button) convertView.findViewById(R.id.delbox);
if(i){
ck.setVisibility(View.VISIBLE);}
else{
ck.setVisibility(View.GONE);
}
ck.setTag(menuListItems.getSlno());
ck.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
final Integer Index = Integer.parseInt((String) v.getTag());
final DataHandler enter = new DataHandler(c);
DialogInterface.OnClickListener dialogClickListener = new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
switch (which){
case DialogInterface.BUTTON_POSITIVE:
//Yes button clicked
enter.open();
enter.delet(Index);
enter.close();
notifyDataSetChanged();
dialog.dismiss();
break;
case DialogInterface.BUTTON_NEGATIVE:
//No button clicked
dialog.dismiss();
break;
}
}
};
AlertDialog.Builder builder = new AlertDialog.Builder(c);
builder.setMessage("Are you sure you want to Delete?").setPositiveButton("Yes", dialogClickListener)
.setNegativeButton("No", dialogClickListener).show();
}
});
TextView id = (TextView) convertView.findViewById(R.id.tvhide);
id.setText(menuListItems.getSlno());
TextView title = (TextView) convertView.findViewById(R.id.tvtitle);
title.setText(menuListItems.getTitle());
TextView phone = (TextView) convertView.findViewById(R.id.tvpnumber);
phone.setText(menuListItems.getPhone());
// ck.setChecked(menuList.)
notifyDataSetChanged();
return convertView;
}

Using javascript to set value of hidden field then access value from serverside c# code | <p>I am using a nested html unordered list styled as a drop down. When the a tag within the inner lists list item is clicked it trigger some javascript which is supposed to set the value of a hidden field to the text for the link that was clicked.</p>
<p>The javascript seems to work - I used an alert to read the value from the hidden field but then when I try to put that value in the querystring in my asp.net c# code behind - it pulls the initial value - not the javascript set value.</p>
<p>I guess this is because the javascript is client side not server side but has anyone any idea how i can get this working</p>

Open downloaded file on Android N using FileProvider | <p>I've got to fix our App for Android N due to the FileProvider changes. I've basically read all about this topic for the last ours, but no solution found did work out for me.</p>
<p>Here's our prior code which starts downloads from our app, stores them in the <code>Download</code> folder and calls an <code>ACTION_VIEW</code> intent as soons as the <code>DownloadManager</code> tells he's finished downloading:</p>
<pre><code>BroadcastReceiver onComplete = new BroadcastReceiver() {
public void onReceive(Context ctxt, Intent intent) {
Log.d(TAG, "Download commplete");
// Check for our download
long referenceId = intent.getLongExtra(DownloadManager.EXTRA_DOWNLOAD_ID, -1);
if (mDownloadReference == referenceId) {
DownloadManager.Query query = new DownloadManager.Query();
query.setFilterById(mDownloadReference);
Cursor c = mDownloadManager.query(query);
if (c.moveToFirst()) {
int columnIndex = c.getColumnIndex(DownloadManager.COLUMN_STATUS);
if (DownloadManager.STATUS_SUCCESSFUL == c.getInt(columnIndex)) {
String localUri = c.getString(c.getColumnIndex(DownloadManager.COLUMN_LOCAL_URI));
String fileExtension = MimeTypeMap.getFileExtensionFromUrl(localUri);
String mimeType = MimeTypeMap.getSingleton().getMimeTypeFromExtension(fileExtension);
if (mimeType != null) {
Intent openFileIntent = new Intent(Intent.ACTION_VIEW);
openFileIntent.setDataAndTypeAndNormalize(Uri.parse(localUri), mimeType);
openFileIntent.setFlags(Intent.FLAG_ACTIVITY_NO_HISTORY);
try {
mAcme.startActivity(openFileIntent);
}
catch (ActivityNotFoundException e) {
// Ignore if no activity was found.
}
}
}
}
}
}
};
</code></pre>
<p>This works on Android M, but breaks on N due to the popular <code>FileUriExposedException</code>. I've now tried to fix this by using the <code>FileProvider</code>, but I cannot get it to work. It's breaking when I try to get the content URI:</p>
<p><code>Failed to find configured root that contains /file:/storage/emulated/0/Download/test.pdf</code></p>
<p>The <code>localUri</code> returned from the <code>DownloadManager</code> for the file is:</p>
<p><code>file:///storage/emulated/0/Download/test.pdf</code></p>
<p>The <code>Environment.getExternalStorageDirectory()</code> returns <code>/storage/emulated/0</code> and this is the code for the conversion:</p>
<pre><code>File file = new File(localUri);
Log.d(TAG, localUri + " - " + Environment.getExternalStorageDirectory());
Uri contentUri = FileProvider.getUriForFile(ctxt, "my.file.provider", file);
</code></pre>
<p>From <code>AndroidManifest.xml</code></p>
<pre><code> <provider
android:name="android.support.v4.content.FileProvider"
android:authorities="my.file.provider"
android:exported="false"
android:grantUriPermissions="true">
<meta-data
android:name="android.support.FILE_PROVIDER_PATHS"
android:resource="@xml/file_paths"/>
</provider>
</code></pre>
<p>The <code>file_paths.xml</code>:</p>
<pre><code><?xml version="1.0" encoding="utf-8"?>
<paths xmlns:android="http://schemas.android.com/apk/res/android">

</paths>

<p>And I've tried all values I could find in that xml file. :(</p> | 0 | 1,594 |

<p>The question is to merge lists having at least one common element. So the results only for the given part will be as follows:</p>
<pre><code>#--------------------------------------
0 [0,1,3,4,5,10,...]
2 [2,8]
#--------------------------------------
</code></pre>
<p><strong>What is the most efficient way to do this on large data (elements are just numbers)?</strong>
Is <code>tree</code> structure something to think about?
I do the job now by converting lists to <code>sets</code> and iterating for intersections, but it is slow! Furthermore I have a feeling that is so-elementary! In addition, the implementation lacks something (unknown) because some lists remain unmerged sometime! Having said that, if you were proposing self-implementation please be generous and provide a simple sample code [apparently <strong>Python</strong> is my favoriate :)] or pesudo-code.<br>
<strong>Update 1:</strong>
Here is the code I was using:</p>
<pre><code>#--------------------------------------
lsts = [[0,1,3],
[1,0,3,4,5,10,11],
[2,8],
[3,1,0,16]];
#--------------------------------------
</code></pre>
<p>The function is (<strong>buggy!!</strong>):</p>
<pre><code>#--------------------------------------
def merge(lsts):
sts = [set(l) for l in lsts]
i = 0
while i < len(sts):
j = i+1
while j < len(sts):
if len(sts[i].intersection(sts[j])) > 0:
sts[i] = sts[i].union(sts[j])
sts.pop(j)
else: j += 1 #---corrected
i += 1
lst = [list(s) for s in sts]
return lst
#--------------------------------------
</code></pre>
<p>The result is:</p>
<pre><code>#--------------------------------------
>>> merge(lsts)
>>> [0, 1, 3, 4, 5, 10, 11, 16], [8, 2]]
#--------------------------------------
</code></pre>
<p><strong>Update 2:</strong>
To my experience the code given by <strong>Niklas Baumstark</strong> below showed to be a bit faster for the simple cases. Not tested the method given by "Hooked" yet, since it is completely different approach (by the way it seems interesting).
The testing procedure for all of these could be really hard or impossible to be ensured of the results. The real data set I will use is so large and complex, so it is impossible to trace any error just by repeating. That is I need to be 100% satisfied of the reliability of the method before pushing it in its place within a large code as a module. Simply for now <strong>Niklas</strong>'s method is faster and the answer for simple sets is correct of course.<br>
<strong>However how can I be sure that it works well for real large data set?</strong> Since I will not be able to trace the errors visually!</p>
<p><strong>Update 3:</strong>
Note that reliability of the method is much more important than speed for this problem. I will be hopefully able to translate the Python code to Fortran for the maximum performance finally.</p>
<p><strong>Update 4:</strong><br>
There are many interesting points in this post and generously given answers, constructive comments. I would recommend reading all thoroughly. Please accept my appreciation for the development of the question, amazing answers and constructive comments and discussion.</p> | 0 | 1,104 |
