"Why doesn't std::to_string support container classes as input?",
"So std::to_string works on various primitive types. However, when trying to print the elements of a container like a vector, I have to iterate through the vector element by element and print each individually. Now granted, with something like a vector this can amount to a single statement or loop like such:\n\nfor_each(v.begin(), v.end(), [](int x) {cout << x <<\", \"; });\n\n\nbut with other container classes it can be quite a nuisance to format the data type. \n\nIn contrast, languages like Java or Python have functions that print most containers in a single statement. Why doesn't STL accept these as arguments in std::to_string or implement to_string as member function of the container classes?"

"Animate div positioning rearrangement",
"I am building a simple push-down effect which affects the position of two containers. So far I have managed to achieve a near-desired effect using fixed positioning for the hidden container while changing its position to a relative for the opened state.\nI want to apply a smooth transition to the blue main div, which is being pushed down by the hidden div with a class of .sub-header. How can I bypass the choppy rearrangement of the containers and is there a more elegant way of doing this instead of switching positioning on click? (e.g. fixed to a relative in this case)\nCurrently, when I switch the positioning from fixed to a relative as expected - there is a gap being produced, which is the .sub-header's height.\n\nNOTE: The heights of the current divs are fixed values, but I need this to be able to handle dynamic changes in the .sub-header height.\nNOTE: This should be achieved by adding a custom class, not using jQuery's nested effects like .slideToggle etc.\n\nHere is the Fiddle.\nAnd the simple jQuery function needed for the Fiddle share:\n$('.trigger').click(function() {\n $('.sub-header').toggleClass('opened');\n}).stop();"

"How to export Google Map to Image including custom markers?",
"As suggested on this answer, I am using html2canvas library to export a Google Map to a image.\n\nI am working on AngularJS. This is the code I am using:\n\n$scope.shareMap = function(){\n var element = $(\"#mapDiv\");\n html2canvas(element, {\n useCORS: true,\n onrendered: function(canvas) {\n var dataUrl= canvas.toDataURL(\"image/png\");\n\n // DO SOMETHING WITH THE DATAURL\n // Eg. write it to the page\n document.write('<img src=\"' + dataUrl + '\"/>');\n }\n });\n };\n\n\nThe thing is, it is not exporting my dynamically generated markers. This markers are generated based on response of an AJAX call.\n\nThis is how it looks with the markers on the web:\n\n\nAnd this is what it exports:\n\n\nAlso, I noticed that if I pan on the map, the \"new\" displayed zone shows in gray, like so:\n\n\nIt seems that it can only export what is shown the first time the map renders (only the map on that specific viewport, without the markers and any additional zones of the map).\n\nIs it possible to solve my problem using this same library? Or can you recommend another approach? Thanks!"

"Syntaxhighlighter V Google's prettify performance advice needed?",
"There have being several threads already about how to prettify code when displaying it on blogspot: How to use prettify with blogger/blogspot? and What are the steps I need to take to add nice java code formatting to my blogger/blogspot blog?.\n\nI have tried google's prettify http://code.google.com/p/google-code-prettify/ and syntaxhighlighter http://alexgorbatchev.com/SyntaxHighlighter/. Both are nice. However, I am interested in which has the better performance of both - this is where this thread differs.\n\nCompression\n\nYSlow is telling me neither is being sent compressed to my browser. However, I am not hosting the site myself, I am using google's blogspot for hosting. So, I don't think there is a lot I can do here. Correct?\n\nCache \nBoth Google's prettify and syntaxhighlighter use javascript files and stylesheets. They host them on a google server and amazon server respectively. if I was hosting files myself I could make use an Apache Http Server and set cache headers on HTTP responses so that returning users don't keep downloading them. If I am not hosting myself and making use of blogspot's free hosting there's nothing I can do, correct?\n\nServer ping time\nThis is a bit a of noddy test. When I ping google's prettify, I get:\n\nPinging googlecode.l.google.com [209.85.143.82] with 32 bytes of data:\nReply from 209.85.143.82: bytes=32 time=5ms TTL=53\nReply from 209.85.143.82: bytes=32 time=4ms TTL=53\nReply from 209.85.143.82: bytes=32 time=4ms TTL=53\nReply from 209.85.143.82: bytes=32 time=5ms TTL=53\n\n\nWhen I ping syntaxhighlighter:\n\nPinging www.alexgorbatchev.com [69.163.149.228] with 32 bytes of data:\nReply from 69.163.149.228: bytes=32 time=148ms TTL=47\nReply from 69.163.149.228: bytes=32 time=146ms TTL=47\nReply from 69.163.149.228: bytes=32 time=146ms TTL=47\nReply from 69.163.149.228: bytes=32 time=146ms TTL=47\n\n\nSo look's like google's winning this one. Probably using a CDN where I don't think syntaxhighlighter is.\n\nFewer Http requests\n\nThere's a difference of approaches here. Syntaxhighlighter is quite modular with different javascript files for different languages. Google;s prettify using one bigger javascript file.\nSo possible to have a smaller filesize with syntax highlighter if you are including snippets from various languages, you'll of course have more http requests.\n\nSo that's the background. The question is what is your performance tip regarding using syntaxhiglighter or google's prettify? How could you make either go faster or ascertain one is faster than the other?\n\nThanks."

I would like to have the problems register themselves at compile time to a global map with a unique key (just an int will work) and have the value be a pointer to the function that kicks off the math problem solution.\n\nThe global map is created and handled in files called Problem.h/Problem.cpp. However, I'm getting an \"Access violation reading location 0x00000004\" when the first Problem attempts to self-register in the map. The code is as follows:\n\nIn the ProblemX.h files (problem1 kicks off the solution for this problem):\n\n#ifndef PROBLEM1_H\n#define PROBLEM1_H\n\n#include \"Problems.h\"\n#include <string>\n\nstd::string problem1();\nstatic int rc1 = registerProblem(1, problem1);\n\n#endif\n\n\nIn the Problems.h file (problemFinder is the function that uses the global map to call the appropriate function pointer):\n\n#ifndef PROBLEMS_H\n#define PROBLEMS_H\n\n#include <string>\n\nint registerProblem(int problemNum, std::string (*problemFunc)(void));\nstd::string problemFinder(int problemNum);\n\n#endif\n\n\nIn Problems.cpp:\n\n#include \"Problems.h\"\n#include <iostream>\n#include <map>\n\nusing namespace std;\n\nmap<int,std::string (*)(void)> problems_map;\n\nint registerProblem(int problemNum, string (*problemFunc)(void)) {\n int rc = 0;\n problems_map[problemNum] = problemFunc;\n return rc;\n}\n\n\nstring problemFinder(int problemNum) {\n string retStr = \"\";\n retStr = problems_map[problemNum]();\n return retStr;\n}\n\n\nThe access violation occurs where \"problems_map[problemNum] = problemFunc;\".\n\nThanks!"

"How to get confirm box return value in ASP.NET C#",
"I know a number of people have asked similar questions already. I've read tons of the answers given but none seems to solve my problem.\nI have a form that allows the user to select a file and pick a date that the file should be imported from. When the date is less (before) the last import period (which is a field in database keeping track of last import dates), I want to display a confirmbox to alert the user that continuing with the import could overwrite some data. The user can choose Yes to continue with import or No to cancel import. I have tried the \n\n\n onClientClick\n\n\nmethod of the \n\n\n asp:Button\n\n\ncontrol. The problem with that was, it gets fired immediately the user clicks the submit button and I don't want to display the confirm box until I have checked with the last import period which will be done on the server-side C#. I have tried writing the return value to a hidden field like this:\n\nif (confirm(\"This Import Process Will Overwrite Existing Data. Do You Want to Continue?\")) {\n document.getElementById(\"ans\").value = \"Yes\";\n return true;\n } else {\n document.getElementById(\"ans\").value = \"No\";\n return false;\n }\n\n\nThat did not work either. I have tried the solution from here: Javascript confirm message problem\n\nSomehow, I can't seem to get it to work with my solution because they have some updatePanel they are using. I am using just the DatePicker, a DropDownList (for selecting which client to import data for) and a hidden field (if required). Please help if you can. I can be a tweak of any of the above or a completely new solution. Thanks."

"how to detect Frame_Enter events from a class module",
"This is a follow-on question to the one answered here:\nHow to detect a mouse_down on a Userform Frame while the mouse is still down\n\nUsing code from the answer to that question, I can successfully detect MouseDown, MouseUp and MouseMove on any frame on the form. However, there's apparently no Frame_Enter or Frame_Exit events available in the cls. Is there a way to simulate a Frame_Enter event in the class module? \n\nEdit:\nHere's what I'm trying to do. I have 8 frames loaded with 8 pictures that, when combined in a larger frame make up a larger picture. Think of a jigsaw with 8 rectangular pieces. Normally, all 8 frames hold a \"dimmed\" (neutral filter overlay) version of their picture, but when the mouse enters any of them it triggers the loading of an \"undimmed\" version of the picture in the newly entered frame, and a dimmed version of the picture in the just exited frame. So if the mouse is over any of these frames, it's always moving over a bright picture that is surrounded by dimmed pictures. \n\nAs the mouse moves around an undimmed frame, it rolls over an unlimited number of \"hotspot\" triggers that cause a textbox to pop up with more info about what the mouse is currently hovering over. When it leaves that frame and moves over another, the process repeats. \n\nEverything is working except for detecting when the mouse moves across a frame boundary and into the next frame. This has to be detected before any MouseMove events can be handled.\n\nHere's a method that looks promising, if nothing else is suggested:\nhttp://www.mrexcel.com/forum/showpost.php?p=2567141&postcount=28\n\nEdit2: It still looks promising but I can't make it work. It doesn't seem to issue the enter and exit events until after I click on the control, which is of no use to me. \n\nSo chris, back to yours. You're watching the Frame_MouseMove events and waiting for a different Frame to issue the event than last time. I'm wondering if instead of using your auxiliary textBox to signal the change, could you not use a static variable to keep track of currentFrame/prevFrame?"
