• User control always crashes Visual Studio

  - by NickAldwin

  I'm trying to open a user control in one of our projects. It was created, I believe, in VS 2003, and the project has been converted to VS2008. I can view the code fine, but when I try to load the designer view, VS stops responding and I have to close it with the task manager. I have tried leaving it running for several minutes, but it does not do anything. I ran "devenv /log" but didn't see anything unusual in the log. I can't find a specific error message anywhere. Any idea what the problem might be? Is there a lightweight editing mode I might be able to use or something? The reason I need to have a look at the visual representation of this control is to decide where to insert some new components. I've tried googling it and searching SO, but either I don't know what to search or there is nothing out there about this. Any help is appreciated. (The strangest thing is that the user control seems to load fine in another project which references, but VS crashes as soon as I even so much as click on it in that project.)

• How to build a web crawler to find a specific advert, which is in an iframe loaded by Javascript

  - by ZoFreX

  I'm trying to find all instances of an advert on a website. The advert is in an iframe which is loaded by javascript (it doesn't appear at all if javascript is turned off). Detecting the advert itself is extremely simple, both the name of the flash file and the target of the href always contain a certain string. What would be the best "starting point" for achieving this? At the moment I'm considering an Adobe AIR app, which could crawl the site and examine the DOM to find the ad, and would run javascript and load the content of the iframe. The other option I can think of is using Firefox as the platform (using maybe GreaseMonkey or Selenium? I don't really know how to leverage Firefox like this). Does anyone know of anything suitable to build this, or have any suggestions on using Firefox to do it? Extra details: Being CPU intensive isn't really an issue, nor is anything depending on a browser being open. This doesn't need to run on a headless server, it will be running on a powerful desktop box. OS is also not an issue. It would be advantageous if the crawler loaded each page multiple times, as the advert is in rotation. While the crawler does need to execute the javascript and load the content of the iframe, it does not need to be able to display flash files.

• SWT: scrollable area within a tab

  - by DaveJohnston

  I am trying to add a scrollable area to my tabbed window. So far I have a CTabFolder in a shell. I have added 5 CTabItems to it and everything works as expected. On one of my CTabItems the contents are too big to fit on the screen so I would like to be able to scroll. The contents is a collection of Groups each containing various widgets. So the CTabFolder is created as follows: CTabFolder tabs = new CTabFolder(shell, SWT.BORDER); tabs.setSimple(false); tabs.setUnselectedImageVisible(false); tabs.setUnselectedCloseVisible(false); tabs.setMinimizeVisible(false); tabs.setMaximizeVisible(false); FormData tabsLayoutData = new FormData(); tabsLayoutData.top = new FormAttachment(0, 5); tabsLayoutData.left = new FormAttachment(0, 5); tabsLayoutData.bottom = new FormAttachment(92, 0); tabsLayoutData.right = new FormAttachment(100, -5); tabs.setLayoutData(tabsLayoutData); Then the CTabItem: CTabItem tab = new CTabItem(tabs, SWT.NONE); tab.setText("Role"); Then the contents: Composite tabArea = new Composite(tabs, SWT.V_SCROLL); tabArea.setLayout(new FormLayout()); tab.setControl(tabArea); So the groups contained within the tab are created with tabArea as the parent and everything appears as you would expect. The problem is though that the vertical scroll bar is always present but doesn't seem to do anything. The contents are chopped off at the bottom of the tabArea composite. Is there anything else I need to do to get the scrolling to work properly?

• How to minify JS in PHP easily...Or something else

  - by RickyAYoder

  I've done some looking around, but I'm still confused a bit. I tried Crockford's JSMin, but Win XP can't unzip the executable file for some reason. What I really want though is a simple and easy-to-use JS minifier that uses PHP to minify JS code--and return the result. The reason why is because: I have 2 files (for example) that I'm working between: scripts.js and scripts_template.js scripts_template is normal code that I write out--then I have to minify it and paste the minified script into scripts.js--the one that I actually USE on my website. I want to eradicate the middle man by simply doing something like this on my page: <script type="text/javascript" src="scripts.php"></script> And then for the contents of scripts.php: <?php include("include.inc"); header("Content-type:text/javascript"); echo(minify_js(file_get_contents("scripts_template.js"))); This way, whenever I update my JS, I don't have to constantly go to a website to minify it and re-paste it into scripts.js--everything is automatically updated. Yes, I have also tried Crockford's PHP Minifier and I've taken a look at PHP Speedy, but I don't understand PHP classes just yet...Is there anything out there that a monkey could understand, maybe something with RegExp? How about we make this even simpler? I just want to remove tab spaces--I still want my code to be readable. It's not like the script makes my site lag epically, it's just anything is better than nothing. Tab removal, anyone? And if possible, how about removing completely BLANK lines?

• Cocoa/AppleScript move file

  - by bogdan

  I have a list of file paths and a destination path. I need something (AppleScript, Cocoa) that will move the files from one location to an other. I first tried using the following AppleScript, just to see what happens: set the_folder to (choose folder) tell application "Finder" move selection to the_folder end tell The problem is that it just blindly tries to move a file, nothing like the way Finder actually moves files (i.e. if a file with that name already exists, the AppleScript just throws an error, while Finder would ask you if you want to replace the file). The solution I came up with involved NSFileManager. I won't post the code because it's quite long, but basically I just check if the file already exists before trying to move, and if it exists a NSAlert with Replace/Cancel buttons appear. I have 2 remaining problems: Authorization - if you try to do something to files where you don't have access, the Finder would ask you to authorize. My code just fails... Moving to external drives - when you try to move a file to a different drive, NSFileManager copies the file and then deletes the original. The problem is that NSFileManager doesn't provide anything which I could use to display a progress indicator of what's happening during the copy. Is there anything I could use that is able to move files without these problems? The way I see it, I'm pretty much stuck with checking if the files are writable by the current user and authorize NSFileManager if not (from my understanding of the Authorization Services, this will be quite hard to implement). Oh and, I would also need to check if the destination is on the same drive and if not, implement something with FSCopyObjectAsync so that it shows a progress indicator... Thanks!

• Bring a subview to the top on mouseDown: AND keep receiving events (for dragging)

  - by d11wtq

  Ok, basically I have a view with a series of slightly overlapping subviews. When a subview is clicked, it moves to the top (among other things), by a really simple two-liner: -(void)mouseDown:(NSEvent *)theEvent { if (_selected) { // Don't do anything this subview is already in the foreground return; } NSView *superview = [self superview]; [self removeFromSuperview]; [superview addSubview:self position:NSWindowAbove relativeTo:nil]; } This works fine and seems to be the "normal" way to do this. The problem is that I'm now introducing some drag logic to the view, so I need to respond to -mouseDragged:. Unfortunately, since the view is removed from the view hierarchy and re-added in the process, I can have the view come to the foreground and be dragged in the same mouse action. It only drags if I leave go of the mouse and click on the view again, since the second click doesn't do any view hierarchy juggling. Is there anything I can do that will allow the view to move to the foreground like this, AND continue to receive the subsequent -mouseDragged: and -mouseUp: events that follow? I started along the lines of thinking of overriding -hitTest: in the superview and intercepting the mouseDown event in order to bring the view to the foreground before it actually receives the event. The problem here is, from within -hitTest:, how do I distinguish what type of event I'm actually performing the hit test for? I wouldn't want to move the subview to the foreground for other mouse events, such as mouseMoved etc.

• How to communicate between frames?

  - by bangoker

  I'm maintaining an application that goes sort of like this: There is a Page A with a Frame that shows Page B. Now page B is part of a completely different product, so there's a frame in a that just calls B. Now, they want that when B an option in B is clicked, the WHOLE page is redirected to another page in A. The problem is that the url of A is something like "www.client.MyCompany/Order/Details/123" But B doesnt know nothing about A, or which order # it is or anything, but Page A who has the frame B does know it. For know my solution is to just redirect to all the order so something like client.MyCompany/Orders but since B doesn't know which client it is, I'll add it in the webconfig. (so each client has its own webconfig with a different value). I dont find this solution optimal but I can't think of anything else! I already tried putting the needed url in page A in a hidden Div (since A does know all the info) and then trying to read the whole DOM of the page from B to find it.... unfortunately I can only get access to Frame B's DOM... (I tried with jquery). I know frames are evil, but this is how it is written... any ideas? Thanks!

• Applications result affected by another running application.

  - by Jamie Keeling

  This is a follow on from my previous question although this is about something else. I've been having a problem where for some reason my message that I pass from one process to another only displays the first letter, in this case "M". My application is based on a MSDN sample so to make sure I hadn't missed something I create a separate solution, added the MSDN sample (without any changes for my needs) and unsurprisingly it works fine. Now for the weird bit, when I run the MSDN sample running (as in debugging) and have my own application running, the text prints out fine without any problems. The second I run my on its own without the original MSDN sample being open, and it fails to work and only shows an "M". I've looked in the debugger and don't seem to notice anything suspicious (it's a slightly dated picture, I've fixed the data type inconsistency). Can anyone provide a solution for this? I've never encountered anything like this before. To look at my source code it's easier to just look at the link I posted at the top of the question, there's no point in me posting it twice. Thank you for any help.

• Improving Performance on this Image Creation function

  - by Abs

  Hello all, I am making use of GD2 and the image functions to take in a string and then convert that into an image using different fonts at different sizes. The function I use is below. Currently, its pretty quick but not quick enough. The function gets called about 20 times per user and the images generated are always new ones (different) so caching isn't going to help! I was hoping to get some ideas on how to make this function faster. Maybe supply more RAM to the script running? Anything else that is specific to this PHP function? Anything else that I can do to tweak performance of this function? function generate_image($save_path, $text, $font_path, $font_size){ $font = $font_path; /* * I have simplifed the line below, its actually a function that works out the size of the box * that is need for each image as the image size is different based on font type, font size etc */ $measure = array('width' => 300, 'height'=> 120); if($measure['width'] > 900){ $measure['width'] = 900; } $im = imagecreatetruecolor($measure['width'], $measure['height']); $white = imagecolorallocate($im, 255, 255, 255); $black = imagecolorallocate($im, 0, 0, 0); imagefilledrectangle($im, 0, 0, $measure['width'], $measure['height'], $white); imagettftext($im, $font_size, 0, $measure['left'], $measure['top'], $black, $font, ' '.$text); if(imagepng($im, $save_path)){ $status = true; }else{ $status = false; } imagedestroy($im); return $status; } Thanks all for any help

• Java SWT: wrapping syncExec and asyncExec to clean up code

  - by jonescb

  I have a Java Application using SWT as the toolkit, and I'm getting tired of all the ugly boiler plate code it takes to update a GUI element. Just to set a disabled button to be enabled I have to go through something like this: shell.getDisplay().asyncExec(new Runnable() { public void run() { buttonOk.setEnabled(true); } }); I prefer keeping my source code as flat as I possibly can, but I need a whopping 3 indentation levels just to do something simple. Is there some way I can wrap it? I would like a class like: public class UIUpdater { public static void updateUI(Shell shell, *function_ptr*) { shell.getDisplay().asyncExec(new Runnable() { public void run() { //Execute function_ptr } }); } } And can be used like so: UIUpdater.updateUI(shell, buttonOk.setEnabled(true)); Something like this would be great for hiding that horrible mess SWT seems to think is necessary to do anything. As I understand it, Java cannot do functions pointers. But Java 7 will have something called Closures which should be what I want. But in the meantime is there anything at all I can do to pass a function pointer or callback to another function to be executed? As an aside, I'm starting to think it'd be worth the effort to redo this application in Swing, and I don't have to put up with this ugly crap and non-cross-platformyness of SWT.

• A standard set of questions to ask an interviewer?

  - by Rob Wells

  We have had many questions for interviewers to ask interviewees. But none addressing information flow in the other direction, interviewee to interviewer. Just an indirect question about "deal breakers" and one about "finding dream jobs". What I'm after is when you're interviewing at a company do you have a set of questions that you like to ask to help get a feel for the company and the work environment? I have a series of questions that I like to ask that range from the development environment to testing techniques to how the team get on together. Anything else you'd like to ask? Edit: I moved my original list of interviewer questions to my answer below. I've also gone through the other answers and added the ones thought were useful in to that answer. The answer is community wiki so feel free to add anything useful. N.B. This is my first cut of categories. Feel free to modify/add/etc. the categories. Or to recategorise the questions themselves.

• ASP.NET AsyncPostBackTrigger disables button's OnClick function???

  - by hahuang65

  I saw another post like this: http://stackoverflow.com/questions/1795621/asyncpostbacktrigger-disables-buttons But I don't really know what to make of it. The accepted answer was poorly typed. Basically, I have a button with an OnClick function. I also have a UpdatePanel, with is AsyncPostBackTrigger set to that same button. It seems that if I do this, my Button no longer does ANYTHING. I guess it's because I have a Page_Load() event... Can anyone explain why this is? And how should I set up my webpage if I can't use the Page_Load() function? Oh and if I put my Button in a UpdatePanel, it also won't do anything, probably because of the same reason. This is a section of my code: <asp:FileUpload id="FileUploadControl" runat="server" /> <asp:Button runat="server" id="UploadButton" text="Upload" OnClick="uploadClicked" /> <br /><br /> <asp:Label runat="server" id="StatusLabel" text="Upload status: " /> <br /> <asp:UpdatePanel ID="UpdatePanel2" runat="server" updatemode="Conditional" > <ContentTemplate> <asp:DropDownList ID="songList" runat="server" /> </ContentTemplate> <Triggers> <asp:AsyncPostBackTrigger ControlID="RefreshButton" /> </Triggers> </asp:UpdatePanel> Thanks in advance.

• Calling DI Container directly in method code (MVC Actions)

  - by fearofawhackplanet

  I'm playing with DI (using Unity). I've learned how to do Constructor and Property injection. I have a static container exposed through a property in my Global.asax file (MvcApplication class). I have a need for a number of different objects in my Controller. It doesn't seem right to inject these throught the constructor, partly because of the high quantity of them, and partly because they are only needed in some Actions methods. The question is, is there anything wrong with just calling my container directly from within the Action methods? public ActionResult Foo() { IBar bar = (Bar)MvcApplication.Container.Resolve(IBar); // ... Bar uses a default constructor, I'm not actually doing any // injection here, I'm just telling my conatiner to give me Bar // when I ask for IBar so I can hide the existence of the concrete // Bar from my Controller. } This seems the simplest and most efficient way of doing things, but I've never seen an example used in this way. Is there anything wrong with this? Am I missing the concept in some way?

• how can a Win32 App plugin load its DLL in its own directory

  - by Jean-Denis Muys

  My code is a plugin for a specific Application, written in C++ using Visual Studio 8. It uses two DLL from an external provider. Unfortunately, my plugin fails to start because the DLLs are not found (I put them in the same directory as the plugin itself). When I manually move or copy the DLLs to the host application directory, then the plugin loads fine. This moving was deemed unacceptably cumbersome for the end user, and I am looking for a way for my plugin to load its DLLs transparently. What can I do? Relevant details: the host Application plugins are located in a directory mandated by the host application. That directory is not in the DLL search path and I don't control it. The plugin is itself packaged as a subdirectory of the plugin directory, holding the plugin code itself, but also any resource associated with the plugin (eg images, configuration files…). I control what's inside that subdirectory, called a "bundle", but not where it's located. the common plugin installation idiom for that App is for the end user to copy the plugin bundle to the plugin directory. This plugin is a port from the Macintosh version of the plugin. On the Mac there is no issue because each binary contains its own dynamic library search path, which I set as I needed to for my plugin binary. To set that on the Mac simply involves a project setting in the Xcode IDE. This is why I would hope for something similar in Visual Studio, but I could not find anything relevant. Moreover, Visual Studio's help was anything but, and neither was Google. A possible workaround would be for my code to explicitly tell Windows where to find the DLL, but I don't know how, and in any case, since my code is not even started, it hasn't got the opportunity to do so. As a Mac developer, I realize that I may be asking for something very elementary. If such is the case, I apologize, but I have run out of hair to pull out.

• How to learn how to program?

  - by twinbornJoint

  I would like to know the best methods for learning to program. I've been directed towards the Python language because I was told it is good for beginners. I ultimately want to make games for OS X/iPhone. My problem is that I understand what I read but I can't apply my knowledge to anything. I am a programming noob. Should I stick with Python? (is there a better language I should be learning?) Where can I learn programming theory? I get very hyper when reading my book sometimes, any tips on staying calm and focusing? What are effective ways to learn how to program? Are there standard exercises for programming? (I feel solving problems helps my understanding immensely) Ultimately I feel like I am in a never ending tunnel that leads me no where. It feels like I am just completely unable to pursue anything in the world of programming, yet it is something I want to do very much. Thanks.

• Windows Service Installation

  - by Goober

  Scenario I have a server, that has NO Visual Studio Installed. It literally has a normal command prompt and nothing installed yet. We don't want to install anything (except the .Net framework which we have already done). We just want to install a bunch of C# Windows Services that we have written. So far I have been installing and running the windows service on my local machine using a "setup and deploy" project that I built into the application, which I could then use to install the service locally. Question How can I install the service on the server? I imagine it can be done from the command prompt only, but what else do I need? - If anything? and where do I put the files that I want to install BEFORE I install them? I imagine I will have to compile the application on my local machine in Visual Studio, then copy it over to the server, and then run an install utility to install it on the server? Any help would be greatly appreciated.

• Low-Hanging Fruit: Obfuscating non-critical values in JavaScript

  - by Piskvor

  I'm making an in-browser game of the type "guess what place/monument/etc. is in this satellite/aerial view", using Google Maps JS API v3. However, I need to protect against cheaters - you have to pass a google.maps.LatLng and a zoom level to the map constructor, which means a cheating user only needs to view source to get to this data. I am already unsetting every value I possibly can without breaking the map (such as center and the manipulation functions like setZoom()), and initializing the map in an anonymous function (so the object is not visible in global namespace). Now, this is of course in-browser, client-side, untrusted JavaScript; I've read much of the obfuscation tag and I'm not trying to make the script bullet-proof (it's just a game, after all). I only need to make the obfuscation reasonably hard against the 1337 Java5kryp7 haxz0rz - "kid sister encryption", as Bruce Schneier puts it. Anything harder than base64 encoding would deter most cheaters by eliminating the lowest-hanging fruit - if the cheater is smart and determined enough to use a JS debugger, he can bypass anything I can do (as I need to pass the value to Google Maps API in plaintext), but that's unlikely to happen on a mass scale (there will also be other, not-code-related ways to prevent cheating). I've tried various minimizers and obfuscators, but those will mostly deal with code - the values are still shown verbatim. TL;DR: I need to obfuscate three values in JavaScript. I'm not looking for bullet-proof armor, just a sneeze-guard. What should I use?

• How to syntax-highlight XML in CDATA elements in Vim?

  - by Jim Hurne

  Vim's syntax highlighting for XML/XSL is great, except it turns off all syntax highlighting in CDATA regions. Is there a way to turn on syntax highlighting on in CDATA regions? At work, we have a lot of XSL code embedded within other XML documents. It would be great if I could get all of the goodness of XML editing for the embedded XSL code as well without having to temporarily remove the CDATA tags, or copy the CDATA content into a temporary file. Example: <root> <someTag><![CDATA[ <xsl:template match="/"> <!-- XSL content here --> </xsl:template> ]]> </someTag> </root> Note that the name of the tag (in the example, someTag) containing the content could be anything. We also sometimes embed Javascript inside CDATA regions as well, and again, it would be nice to turn on Javascript syntax highlighting for those regions. Again, the tag the data is embedded in is usually arbitrary and can be anything.

• Returning objects from another thread?

  - by Mark

  Trying to follow the hints laid out here, but she doesn't mention how to handle it when your collection needs to return a value, like so: private delegate TValue DequeueHandler(); public virtual TValue Dequeue() { if (dispatcher.CheckAccess()) { --count; var pair = dict.First(); var queue = pair.Value; var val = queue.Dequeue(); if (queue.Count == 0) dict.Remove(pair.Key); OnCollectionChanged(new NotifyCollectionChangedEventArgs(NotifyCollectionChangedAction.Remove, val)); return val; } else { dispatcher.BeginInvoke(new DequeueHandler(Dequeue)); } } This obviously won't work, because dispatcher.BeginInvoke doesn't return anything. What am I supposed to do? Or maybe I could replace dequeue with two functions, Peek and Pop, where Peek doesn't really need to be on the UI thread because it doesn't modify anything, right? As a side question, these methods don't need to be "locked" either, do they? If they're all forced to run in the UI thread, then there shouldn't be any concurrency issues, right?

• Eclipse Juno won't create Android Activity

  - by MikkoP

  I downloaded Eclipse Juno Java EE edition and installed ADT plugin. I created a new Android Application Project from Eclipse and in the wizard I created an activity called TaskariActivity. After I pressed finish, it created the project but not the activity and the wizard didn't close. I pressed cancel. No activity or anything in the src folder. I created a new activity by right clicking on src, selecting new -> other -> Android -> activity. I selected BlankActivity (as earlier when I was creating the project), selected the earlier created project in the Project combo box. I set the Activity name as TaskariActivity, layout name as activity_main and title as TaskariActivity. Next I selected navigation type and I set it to Tabs + Swipe (I thought this would make me tabs and everything I had to do would be just inserting the elements and the actions for them). I pressed next, nothing happened. Finish didn't also do anything. I pressed cancel and an activity wasn't created. So, how can I create an Android application like in the earlier version of Eclipse? It automatically created the activity and it was ready be run out of the box. Now it won't generate any files and the new activity wizard doesn't work. Help?

• Java EE Website Planning Questions

  - by Tom Tresansky

  I'm a .NET programming who is soon moving to the Java EE world. I have plenty of experience with .NET web technologies, web services, WebForms and MVC. I am also very familiar with the Java language, and have written a few servlets and modified a couple of JSP pages, but I haven't touched EE yet. I'd like to set up a public website using Java EE so I can familiarize myself with whats current. I'm thinking just a technology playground at this point with no particular purpose in mind. What Java technologies are the current hotness for this sort of thing? (For example, if someone asked me what I'd recommend learning to set up a new .NET site, I'd say use ASP MVC instead of WebForms and recommend LINQ-to-SQL as a quick, simple and widely used ORM.) So, what I'd like to know is: Is there a recommended technology for the presentation layer? Is JSP considered a good approach, or is there anything cleaner/newer/more widespread? Is Hibernate still widely used for persistence? Is it obsolete? Is there anything better out there? (I've worked with NHibernate some, so I wouldn't be starting from scratch.) Is cheap Java EE web hosting available? What should I know being a .NET web developer moving to the Java world?

• Creating a Pop animation similar to the presentation of UIAlertView

  - by JK

  I would like to present a view in the same manner as that of UIAlertView - a pop/spring. Unfortunately subclassing UIAlertView is not an option for the view I need to present. I have written some code, but I can't seem to get it as realistic as I would like. I would appreciate any suggestions for greater realism or a link if anything similar has been done (I could not find anything on Google).

• Syncing magento database froms development to production

  - by ringerce

  I use git for version control. I have a development, staging and production environment. When I finish in development I push to staging for review by the client. When approved, I push changes from staging to production. That works fine as long as there is no database changes. What happens if I install modules via Magento connect on local development and it makes database modifications. How would I push those changes up to the production server since the production server is always changing? Edit: I wrote two shell scripts. One that pulls the production database down to my development server, replaces base url with develpment url and updates my development db accordingly. It also leaves the production sql dump behind to be added to my git repo. I'm not really sure if it's beneficial to keep the raw dumps in source control but I'm going to try it out. The second scripts moves the development database up to staging and essentially performs the same operations as the first. Now when it comes time to move to production I pull the updated production repo into the production server and allow magento to do it's thing. I also started using SQLYog recently and it has a database comparison wizard which will give me the differences in my development and production databases and allow me to merge the changes in selectively. It always creates a migration script that I added to source control as well. If anything goes wrong I can run the comparison to see if anything was missed. Does this sounds like a decent workflow to you guys?

• Create a Task list, with tasks without executing

  - by Ernesto Araya Eguren

  I have an async method private async Task DoSomething(CancellationToken token) a list of Tasks private List<Task> workers = new List<Task>(); and I have to create N threads that runs that method public void CreateThreads(int n) { tokenSource = new CancellationTokenSource(); token = tokenSource.Token; for (int i = 0; i < n; i++) { workers.Add(DoSomething(token)); } } but the problem is that those have to run at a given time public async Task StartAllWorkers() { if (0 < workers.Count) { try { while (0 < workers.Count) { Task finishedWorker = await Task.WhenAny(workers.ToArray()); workers.Remove(finishedWorker); finishedWorker.Dispose(); } if (workers.Count == 0) { tokenSource = null; } } catch (OperationCanceledException) { throw; } } } but actually they run when i call the CreateThreads Method (before the StartAllWorkers). I searched for keywords and problems like mine but couldn't find anything about stopping the task from running. I've tried a lot of different aproaches but anything that could solve my problem entirely. For example, moving the code from DoSomething into a workers.Add(new Task(async () => { }, token)); would run the StartAllWorkers(), but the threads will never actually start. There is another method for calling the tokenSource.Cancel().

• G++ Multi-platform memory leak detection tool

  - by indyK1ng

  Does anyone know where I can find a memory memory leak detection tool for C++ which can be either run in a command line or as an Eclipse plug-in in Windows and Linux. I would like it to be easy to use. Preferably one that doesn't overwrite new(), delete(), malloc() or free(). Something like GDB if its gonna be in the command line, but I don't remember that being used for detecting memory leaks. If there is a unit testing framework which does this automatically, that would be great. This question is similar to other questions (such as http://stackoverflow.com/questions/283726/memory-leak-detection-under-windows-for-gnu-c-c ) however I feel it is different because those ask for windows specific solutions or have solutions which I would rather avoid. I feel I am looking for something a bit more specific here. Suggestions don't have to fulfill all requirements, but as many as possible would be nice. Thanks. EDIT: Since this has come up, by "overwrite" I mean anything which requires me to #include a library or which otherwise changes how C++ compiles my code, if it does this at run time so that running the code in a different environment won't affect anything that would be great. Also, unfortunately, I don't have a Mac, so any suggestions for that are unhelpful, but thank you for trying. My desktop runs Windows (I have Linux installed but my dual monitors don't work with it) and I'd rather not run Linux in a VM, although that is certainly an option. My laptop runs Linux, so I can use that tool on there, although I would definitely prefer sticking to my desktop as the screen space is excellent for keeping all of the design documentation and requirements in view without having to move too much around on the desktop. NOTE: While I may try answers, I won't mark one as accepted until I have tried the suggestion and it is satisfactory. EDIT2: I'm not worried about the cross-platform compatibility of my code, it's a command line application using just the C++ libraries.
