  • converting 2D mouse coordinates to 3D space in OpenGL ES

    - by Jayesh
    I want to convert mouse's current X and Y coordinates into the 3D space I have drawn in the viewport. I need to do this on the OpenGL ES platform. I found following possible solutions implemented in OpenGL, but none fits what I am looking for. I found NeHe's tutorial on doing exactly this, but in traditional OpenGL way. It uses gluUnProject. http://nehe.gamedev.net/data/articles/article.asp?article=13 Although gluUnProject is not available in OpenGL ES, its implementation seems simple enough to port back. But before calling it, we need to call glReadPixels with GL_DEPTH_COMPONENT and that is not possible in OpenGL ES. (The reason I found in this thread: http://www.khronos.org/message_boards/viewtopic.php?f=4&t=771) What I want to do is similar to picking, except that I don't want to select the object but I want exact coordinates so that I can recognize particular portion of the object that is currently under mouse cursor. I went through the Picking tutorials in this answer. http://stackoverflow.com/posts/2211312/revisions But they need glRenderMode, which I believe is absent in OpenGL ES. If you know how to solve this problem in OpenGL ES, please let me know. Thanks.

  • Silverlight ScriptableMember in Firefox 'Content is undefined' error.

    - by Sergey Mirvoda
    Recently I'm learned how to call SIlverlight methods from JavaScript. All works fine (even in Chrome !). But in FireFox 3 (3.6.4) registered Page object is undefined.

  • Why doesn't TransactionScope work with Entity Framework?

    - by NotDan
    See the code below. If I initialize more than one entity context, then I get the following exception on the 2nd set of code only. If I comment out the second set it works. {"The underlying provider failed on Open."} Inner: {"Communication with the underlying transaction manager has failed."} Inner: {"Error HRESULT E_FAIL has been returned from a call to a COM component."} Note that this is a sample app and I know it doesn't make sense to create 2 contexts in a row. However, the production code does have reason to create multiple contexts in the same TransactionScope, and this cannot be changed. Edit Here is a previous question of me trying to set up MS-DTC. It seems to be enabled on both the server and the client. I'm not sure if it is set up correctly. Also note that one of the reasons I am trying to do this, is that existing code within the TransactionScope uses ADO.NET and Linq 2 Sql... I would like those to use the same transaction also. (That probably sounds crazy, but I need to make it work if possible). http://stackoverflow.com/questions/794364/how-do-i-use-transactionscope-in-c Solution Windows Firewall was blocking the connections to MS-DTC. using(TransactionScope ts = new System.Transactions.TransactionScope()) { using (DatabaseEntityModel o = new DatabaseEntityModel()) { var v = (from s in o.Advertiser select s).First(); v.AcceptableLength = 1; o.SaveChanges(); } //-> By commenting out this section, it works using (DatabaseEntityModel o = new DatabaseEntityModel()) { //Exception on this next line var v = (from s1 in o.Advertiser select s1).First(); v.AcceptableLength = 1; o.SaveChanges(); } //-> ts.Complete(); }

  • Jqgrid: navigation based on the selected row

    - by bsreekanth
    Hello, I was trying to enable navigation based on a selected row. So, the user select a row from jQgrid, and when press the show (is there a show button for the grid, I saw edit, add etc), it needs to go to a new page based on the url (part of the row). $(document).ready(function () { function getLink() { // var rowid = $("#customer_list").jqGrid('getGridParam', 'selrow'); var rowid = $("#customer_list").getGridParam('selrow'); var MyCellData = $("#customer_list").jqGrid('getCell', rowid, 'dataUrl'); return MyCellData; } $("#customer_list").jqGrid({ url:'mytestList', editurl:'jq_edit_test', datatype: "json", colNames:['Call Id','Title','dataUrl'], colModel:[ {name:'callId', width:80, search:false }, {name:'title', width:200, sortable:false }, {name:'dataUrl',hidden:true} ], rowNum:10, sortname:'lastUpdated', sortorder: 'desc', pager:'#customer_list_pager', viewrecords: true, gridview: true }).navGrid('#customer_list_pager', {add:true,edit:true,del:false,search:true,refresh:true}, {closeAfterEdit:true, afterSubmit:afterSubmitEvent }, // edit options {addCaption:'Create New something', afterSubmit:afterSubmitEvent, savekey:[true,13]}, // add options {afterSubmit:afterSubmitEvent} // delete options ); $("#customer_list").jqGrid('filterToolbar'); }); so, the url is passed for each row as dataUrl. I'm trying to read it and set to the button. Whn debug through firebug, the rowid was 223 (there were only 12 rows in the grid), and the cell value is empty. Currently the button is kept outside the grid, but it may better to be it part of the vavGrid thanks.

  • IOs7 app crashing when in background

    - by Leonardo
    My app sometimes crashes when in background and shows the following crash log: Nov 7 12:33:31 iPad backboardd[29] <Warning>: MyApp[3096] has active assertions beyond permitted time: {( <BKProcessAssertion: 0x14680c60> identifier: Called by MyApp, from -[AppDelegate applicationDidEnterBackground:] process: MyApp[3096] permittedBackgroundDuration: 180.000000 reason: finishTask owner pid:3096 preventSuspend preventIdleSleep preventSuspendOnSleep )} Looking through other questions I found out that the crash message indicates that I didn't end a task properly, so when its time expired the OS ended it and crashed my app. So I added some NSLogs: - (void)applicationDidEnterBackground:(UIApplication *)application { [self saveContext]; [Settings setCallLock:YES]; [self saveStuff]; if ([self isBackgroundTaskNeeded]) { UIApplication* app = [UIApplication sharedApplication]; bgTask = [app beginBackgroundTaskWithExpirationHandler:^{ [self pauseDownloads]; NSLog(@"Debug - Ending background task %d",bgTask); [app endBackgroundTask:bgTask]; NSLog(@"Debug - Background task %d ended",bgTask); bgTask = UIBackgroundTaskInvalid; }]; NSLog(@"Debug - Starting background task %d",bgTask); [self initBackground]; } } and found out that the task was called twice when it crashed: Nov 7 12:30:02 iPad MyApp[3096] <Warning>: Debug - Starting background task 7 Nov 7 12:30:30 iPad MyApp[3096] <Warning>: Debug - Starting background task 8 Nov 7 12:33:26 iPad MyApp[3096] <Warning>: Debug - Ending background task 8 Nov 7 12:33:26 iPad MyApp[3096] <Warning>: Debug - Background task 8 ended Nov 7 12:33:26 iPad MyApp[3096] <Warning>: Debug - Ending background task 0 Nov 7 12:33:26 iPad MyApp[3096] <Warning>: Debug - Background task 0 ended I wasn't able to tell when the double call happens and why. So question is why is the task being called twice and is there a way to avoid it? Edit: - (void) pauseDownloads { for (AFDownloadRequestOperation *operation in self.operationQueue.operations) { if(![operation isPaused]) { [operation pause]; } } }

  • How to fix the endless printing loop bug in Nevrona Rave

    - by Sean B. Durkin
    Nevrona Designs' Rave Reports is a Report Engine for use by Embarcadero's Delphi IDE. This is what I call the Rave Endless Loop bug. In Rave Reports version 6.5.0 (VCL10) that comes bundled with Delphi 2006, there is a nortorious bug that plagues many Rave report developers. If you have a non-empty dataset, and the data rows for this dataset fit exactly into a page (that is to say there are zero widow rows), then upon PrintPreview, Rave will get stuck in an infinite loop generating pages. This problem has been previously reported in this newsgroup under the following headings: "error: generating infinite pages"; Hugo Hiram 20/9/2006 8:44PM "Rave loop bug. Please help"; Tomas Lazar 11/07/2006 7:35PM "Loop on full page of data?"; Tony Chistiansen 23/12/2004 3:41PM reply to (3) by another complainant; Oliver Piche "Endless lopp print bug"; Richso 9/11/2004 4:44PM In each of these postings, there was no response from Nevrona, and no solution was reported. Possibly, the problem has also been reported on an allied newsgroup (nevrona.public.rave.reports.general), to wit: 6. "Continuously generating report"; Jobard 20/11/2005 Although it is not clear to me if (6) is the Rave Endless loop bug or another problem. This posting did get a reply from Nevrona, but it was more in relation to multiple regions ("There is a problem when using multiple regions that go over a page-break.") than the problem of zero widows.

  • handling refrence to pointers/double pointers using SWIG [C++ to Java]

    - by Siddu
    My code has an interface like class IExample { ~IExample(); //pure virtual methods ...}; a class inheriting the interface like class CExample : public IExample { protected: CExample(); //implementation of pure virtual methods ... }; and a global function to create object of this class - createExample( IExample *& obj ) { obj = new CExample(); } ; Now, I am trying to get Java API wrapper using SWIG, the SWIG generated interface has a construcotr like - IExample(long cPtr, boolean cMemoryOwn) and global function becomes createExample(IExample obj ) The problem is when i do, IExample exObject = new IExample(LogFileLibraryJNI.new_plong(), true /*or false*/ ); createExample( exObject ); The createExample(...) API at C++ layer succesfully gets called, however, when call returns to Java layer, the cPtr (long) variable does not get updated. Ideally, this variable should contain address of CExample object. I read in documentation that typemaps can be used to handle output parameters and pointer references as well; however, I am not able to figure out the suitable way to use typemaps to resolve this problem, or any other workaround. Please suggest if i am doing something wrong, or how to use typemap in such situation?

  • Silverlight WCF netTcpBinding problem

    - by JontyMC
    Trying to call a WCF with a netTcpBinding via Silverlight, I am getting the error: "TCP error code 10013: An attempt was made to access a socket in a way forbidden by its access permissions.. This could be due to attempting to access a service in a cross-domain way while the service is not configured for cross-domain access. You may need to contact the owner of the service to expose a sockets cross-domain policy over HTTP and host the service in the allowed sockets port range 4502-4534." My WCF service is hosted in IIS7, bound to: http://localhost.myserivce.com on port 80 and net.tcp on port 4502 I can see http://localhost.myserivce.com/myservice.svc if I browse to it (my hosts file is pointing this domain to localhost).

  • Sending formatted Lotus Notes rich text email from Excel VBA

    - by Lunatik
    I have little Lotus Script or Notes/Domino knowledge but I have a procedure, copied from somewhere a long time ago, that allows me to email through Notes from VBA. I normally only use this for internal notifications where the formatting hasn't really mattered. I now want to use this to send external emails to a client, and corporate types would rather the email complied with our style guide (a sans-serif typeface basically). I was about to tell them that the code only works with plain text, but then I noticed that the routine does reference some sort of CREATERICHTEXTITEM object. Does this mean I could apply some sort of formatting to the body text string after it has been passed to the mail routine? As well as upholding our precious brand values, this would be quite handy to me for highlighting certain passages in the email. I've had a dig about the 'net to see if this code could be adapted, but being unfamiliar with Notes' object model, and the fact that online Notes resources seem to mirror the application's own obtuseness, meant I didn't get very far. The code: Sub sendEmail(EmailSubject As String, EMailSendTo As String, EMailBody As String, MailServer as String) Dim objNotesSession As Object Dim objNotesMailFile As Object Dim objNotesDocument As Object Dim objNotesField As Object Dim sendmail As Boolean 'added for integration into reporting tool Dim dbString As String dbString = "mail\" & Application.UserName & ".nsf" On Error GoTo SendMailError 'Establish Connection to Notes Set objNotesSession = CreateObject("Notes.NotesSession") On Error Resume Next 'Establish Connection to Mail File Set objNotesMailFile = objNotesSession.GETDATABASE(MailServer, dbString) 'Open Mail objNotesMailFile.OPENMAIL On Error GoTo 0 'Create New Memo Set objNotesDocument = objNotesMailFile.createdocument Dim oWorkSpace As Object, oUIdoc As Object Set oWorkSpace = CreateObject("Notes.NotesUIWorkspace") Set oUIdoc = oWorkSpace.CurrentDocument 'Create 'Subject Field' Set objNotesField = objNotesDocument.APPENDITEMVALUE("Subject", EmailSubject) 'Create 'Send To' Field Set objNotesField = objNotesDocument.APPENDITEMVALUE("SendTo", EMailSendTo) 'Create 'Copy To' Field Set objNotesField = objNotesDocument.APPENDITEMVALUE("CopyTo", EMailCCTo) 'Create 'Blind Copy To' Field Set objNotesField = objNotesDocument.APPENDITEMVALUE("BlindCopyTo", EMailBCCTo) 'Create 'Body' of memo Set objNotesField = objNotesDocument.CREATERICHTEXTITEM("Body") With objNotesField .APPENDTEXT emailBody .ADDNEWLINE 1 End With 'Send the e-mail Call objNotesDocument.Save(True, False, False) objNotesDocument.SaveMessageOnSend = True 'objNotesDocument.Save objNotesDocument.Send (0) 'Release storage Set objNotesSession = Nothing Set objNotesMailFile = Nothing Set objNotesDocument = Nothing Set objNotesField = Nothing 'Set return code sendmail = True Exit Sub SendMailError: Dim Msg Msg = "Error # " & Str(Err.Number) & " was generated by " _ & Err.Source & Chr(13) & Err.Description MsgBox Msg, , "Error", Err.HelpFile, Err.HelpContext sendmail = False End Sub

  • Android ASync task ProgressDialog isn't showing until background thread finishes

    - by jackbot
    I've got an Android activity which grabs an RSS feed from a URL, and uses the SAX parser to stick each item from the XML into an array. This all works fine but, as expected, takes a bit of time, so I want to use AsyncActivity to do it in the background. My code is as follows: class AddTask extends AsyncTask<Void, Item, Void> { protected void onPreExecute() { pDialog = ProgressDialog.show(MyActivity.this,"Please wait...", "Retrieving data ...", true); } protected Void doInBackground(Void... unused) { items = parser.getItems(); for (Item it : items) { publishProgress(it); } return(null); } protected void onProgressUpdate(Item... item) { adapter.add(item[0]); } protected void onPostExecute(Void unused) { pDialog.dismiss(); } } Which I call in onCreate() with new AddTask().execute(); The line items = parser.getItems() works fine - items being the arraylist containing each item from the XML. The problem I'm facing is that on starting the activity, the ProgressDialog which i create in onPreExecute() isn't displayed until after the doInBackground() method has finished. i.e. I get a black screen, a long pause, then a completely populated list with the items in. Why is this happening? Why isn't the UI drawing, the ProgressDialog showing, the parser getting the items and incrementally adding them to the list, then the ProgressDialog dismissing?

  • Using QTDesigner with PyQT and Python 2.6

    - by PyNewbie27
    Hi. I'm fairly new to Python and trying to work with the latest versions of QTDesigner, PyQT 4.7 and QT4.7 (I downloaded the whole package from PyQT4.7 website). I can't figure out how to make QTDesigner integrate closely with Python: ie. If I select "Form" View Code in QTDesigners menu, it errors saying "Unable to launch C:/Python26/Lib/site-packages/PyQT4/bin\uic." If I look in that directory there is a pyuic.py but not "uic". From searching online it seems this doesn't exist because it's expecting a C++ install instead of the python version. Is there anyway to make QTDesigner use/call pyuic.py to generate the code, then open an IDE or text editor of my choice to show me the PYTHON code generated by the QTDesigner-PyUIC chain? I'd like Designer to integrate closely with python, so I can make custom slots/signals in Designer while designing, then tweak the python code directly in my IDE later. If it is not possible to code directly inside QTDesigner using python, does that mean I have to hand code my programs entire UI directly in my PythonIDE? Using Designer directly would seemingly be nearly very very nice for a newbie such as myself, since I can see what properties each widget has and visually edit them while still learning the QT syntax without constantly having to use web resources to see what properties each widget should have and helps with boilerplate code generation, and what their defaults are, etc. I've googled and nobody seems to be using QTDesigner and Python in this manner together. It seems most are either handcoding all the QT code in their Python IDE of choice, or have found an obvious/easy method of doing what I want, therefore not really producing up to date tutorials on making this work together. Please enlighten me if you can. Thanks in advance for your time. Please include any suggestions you might have to a newbie trying to use Python with QT and QTDesigner. Thank you.

  • How to create a dynamic Linq Join extension method

    - by Royd Brayshay
    There was a library of dynamic Linq extensions methods released as a sample with VS2008. I'd like to extend it with a Join method. The code below fails with a parameter miss match exception at run time. Can anyone find the problem? public static IQueryable Join(this IQueryable outer, IEnumerable inner, string outerSelector, string innerSelector, string resultsSelector, params object[] values) { if (inner == null) throw new ArgumentNullException("inner"); if (outerSelector == null) throw new ArgumentNullException("outerSelector"); if (innerSelector == null) throw new ArgumentNullException("innerSelector"); if (resultsSelector == null) throw new ArgumentNullException("resultsSelctor"); LambdaExpression outerSelectorLambda = DynamicExpression.ParseLambda(outer.ElementType, null, outerSelector, values); LambdaExpression innerSelectorLambda = DynamicExpression.ParseLambda(inner.AsQueryable().ElementType, null, innerSelector, values); ParameterExpression[] parameters = new ParameterExpression[] { Expression.Parameter(outer.ElementType, "outer"), Expression.Parameter(inner.AsQueryable().ElementType, "inner") }; LambdaExpression resultsSelectorLambda = DynamicExpression.ParseLambda(parameters, null, resultsSelector, values); return outer.Provider.CreateQuery( Expression.Call( typeof(Queryable), "Join", new Type[] { outer.ElementType, inner.AsQueryable().ElementType, outerSelectorLambda.Body.Type, innerSelectorLambda.Body.Type, resultsSelectorLambda.Body.Type }, outer.Expression, inner.AsQueryable().Expression, Expression.Quote(outerSelectorLambda), Expression.Quote(innerSelectorLambda), Expression.Quote(resultsSelectorLambda))); } I've now fixed it myself, here's the answer. Please vote it up or add a better one.

  • How can I beta test web Perl modules under Apache/mod_perl on production web server?

    - by DVK
    We have a setup where most code, before being promoted to full production, is deployed in BETA mode - meaning, it runs in full production environment (using production database - usually production data; and production web server). We call that stage BETA testing. One of the main requirements is that BETA code promotion to production must be a simple "cp" command from beta to production directory - no code/filename changes. For non-web Perl code, achieving seamless BETA test is quite doable (see details here): Perl programs live in a standard location under production root (/usr/code/scripts) with production perl modules living under the same root (/usr/code/lib/perl) The BETA code has 100% same code paths except under beta root (/usr/code/beta/) A special module manipulates @INC of any script based on whether the script was called from /usr/code/scripts or /usr/code/test/scripts, to include beta libraries for beta scripts. This setup works fine up till we need to beta test our web Perl code (the setup is EmbPerl and Apache/mod_perl). The hang-up is as follows: if both a production Perl module and BETA Perl module have the same name (e.g. /usr/code/lib/perl/MyLib1.pm and /usr/code/beta/lib/perl/MyLib1.pm), then mod_perl will only be able to load ONE of these modules into memory - and there's no way we are aware of for a particular web page to affect which version of the module is currently loaded due to concurrency issues. Leaving aside the obvious non-programming solution (get a bloody BETA web server) which for political/organizational reasons is not feasible, is there any way we can somehow hack around this problem in either Perl or mod_perl? I played around with various approaches to unloading Perl modules that %INC has listed, but the problem remains that another user might load a beta page at just the right (or rather wrong) moment and have the beta module loaded which will be used for my production page.

  • Is Appcelerator Titanium now banned on the iPhone?

    - by altuzar
    This question has been answered quite clearly for MonoTouch here: http://stackoverflow.com/questions/2604033/is-monotouch-now-banned-on-the-iphone But what about Appcelerator Titanium? The new TOS from Apple and their iPhone 4 OS: 3.3.1 — Applications may only use Documented APIs in the manner prescribed by Apple and must not use or call any private APIs. Applications must be originally written in Objective-C, C, C++, or JavaScript as executed by the iPhone OS WebKit engine, and only code written in C, C++, and Objective-C may compile and directly link against the Documented APIs (e.g., Applications that link to Documented APIs through an intermediary translation or compatibility layer or tool are prohibited). Titanium uses JavaScript but is not executed be the iPhone OS WebKit engine directly. In their Developer blog, Jeff Haynie says Titanium is on the clear, but I don't know if they are in denial. It’s our belief that we are fully in compliance with iPhone OS 4.0 ToS as we interpret them. I haven't found any official word by Apple, only opinions. And I'm quite confussed. I'm not writing another line of code for my App until... you know.

  • Manually iterating over a selection of XML elements (C#, XDocument)

    - by user316117
    What is the “best practice” way of manually iterating (i.e., one at a time with a “next” button) over a set of XElements in my XDocument? Say I select the set of elements I want thusly: var elems = from XElement el in m_xDoc.Descendants() where (el.Name.LocalName.ToString() == "q_a") select el; I can use an IEnumerator to iterate over them, i.e., IEnumerator m_iter; But when I get to the end and I want to wrap around to the beginning if I call Reset() on it, it throws a NotSupportedException. That’s because, as the Microsoft C# 2.0 Specification under chapter 22 "Iterators" says "Note that enumerator objects do not support the IEnumerator.Reset method. Invoking this method causes a System.NotSupportedException to be thrown ." So what IS the right way of doing this? And what if I also want to have bidirectional iteration, i.e., a “back” button, too? Someone on a Microsoft discussion forum said I shouldn’t be using IEnumerable directly anyway. He said there was a way to do what I want with LINQ but I didn’t understand what. Someone else suggested dumping the XElements into a List with ToList(), which I think would work, but I wasn’t sure it was “best practice”. Thanks in advance for any suggestions!

  • WCF "The server did not provide a meaningful reply"

    - by Nelson
    I am out of ideas here, so I'm hoping someone can help. Here is what I've got: A WCF service that only has a basicHttpBinding endpoint. There is only a service interface, all other [DataMember], [FaultContract] are concrete types. When I run it straight from Visual Studio (using WCF Test Client or my custom app) everything works (I send a request and get a response). This usually takes a second or two. I published it to an IIS 6 server. I can successfully open http://server/WebService/WebService.svc?WSDL I can successfully open http://server/WebService/WebService.svc/mex (same output as above) The WCF Test Client and my custom app can successfully add the service reference Whenever I try to call a service method it waits for about 15 seconds and I get the dreaded "no meaningful reply" error. I ran Fiddler and I got a 202 result, which would seem like a success. It's not returning more than 65536 bytes It's returning an array, but it is small I tried remote debugging, but can't get that to work, probably due to a firewall (but port 80 is open, I can get the WSDL) I enabled system.diagnostics, nothing. I have an IErrorHandler which normally logs things, nothing. Here's the endpoint config: <endpoint address="" binding="basicHttpBinding" contract="Enterprise.IMyService" bindingNamespace="http://ourdomain.com/MyService/"> <identity> <dns value="localhost" /> </identity> </endpoint> Anything else I can try? It's probably a simple setting somewhere, but I can't figure it out.

  • Rewind request body stream

    - by Despertar
    I am re-implementing a request logger as Owin Middleware which logs the request url and body of all incoming requests. I am able to read the body, but if I do the body parameter in my controller is null. I'm guessing it's null because the stream position is at the end so there is nothing left to read when it tries to deserialize the body. I had a similar issue in a previous version of Web API but was able to set the Stream position back to 0. This particular stream throws a This stream does not support seek operations exception. In the most recent version of Web API 2.0 I could call Request.HttpContent.ReadAsStringAsync()inside my request logger, and the body would still arrive to the controller in tact.

  • Python ImportError when executing 'import.py', but not when executing 'python import.py'

    - by Martin Del Vecchio
    I am running Cygwin Python version 2.5.2. I have a three-line source file, called import.py: #!/usr/bin/python import xml.etree.ElementTree as ET print "Success!" When I execute "python import.py", it works: C:\Temp>python import.py Success! When I run the python interpreter and type the commands, it works: C:\Temp>python Python 2.5.2 (r252:60911, Dec 2 2008, 09:26:14) [GCC 3.4.4 (cygming special, gdc 0.12, using dmd 0.125)] on cygwin Type "help", "copyright", "credits" or "license" for more information. >>> #!/usr/bin/python ... import xml.etree.ElementTree as ET >>> print "Success!" Success! >>> But when I execute "import.py', it does not work: C:\Temp>which python /usr/bin/python C:\Temp>import.py Traceback (most recent call last): File "C:\Temp\import.py", line 2, in ? import xml.etree.ElementTree as ET ImportError: No module named etree.ElementTree When I remove the first line (#!/usr/bin/python), I get the same error. I need that line in there, though, for when this script runs on Linux. And it works fine on Linux. Any ideas? Thanks.

  • How to use Application Verifier to find memory leaks

    - by Patrick
    I want to find memory leaks in my application using standard utilities. Previously I used my own memory allocator, but other people (yes, you Neil) suggested to use Microsoft's Application Verifier, but I can't seem to get it to report my leaks. I have the following simple application: #include <iostream> #include <conio.h> class X { public: X::X() : m_value(123) {} private: int m_value; }; void main() { X *p1 = 0; X *p2 = 0; X *p3 = 0; p1 = new X(); p2 = new X(); p3 = new X(); delete p1; delete p3; } This test clearly contains a memory leak: p2 is new'd but not deleted. I build the executable using the following command lines: cl /c /EHsc /Zi /Od /MDd test.cpp link /debug test.obj I downloaded Application Verifier (4.0.0665) and enabled all checks. If I now run my test application I can see a log of it in Application Verifier, but I don't see the memory leak. Questions: Why doesn't Application Verifier report a leak? Or isn't Application Verifier really intended to find leaks? If it isn't which other tools are available to clearly report leaks at the end of the application (i.e. not by taking regular snapshots and comparing them since this is not possible in an application taking 1GB or more), including the call stack of the place of allocation (so not the simple leak reporting at the end of the CRT) If I don't find a decent utility, I still have to rely on my own memory manager (which does it perfectly).

  • .NET C#: WebBrowser control Navigate() does not load targeted URL

    - by Dave
    Hey guys, I'm trying to programmatically load a web page via the WebBrowser control with the intent of testing the page & it's JavaScript functions. Basically, I want to compare the HTML & JavaScript run through this control against a known output to ascertain whether there is a problem. However, I'm having trouble simply creating and navigating the WebBrowser control. The code below is intended to load the HtmlDocument into the WebBrowser.Document property: WebBrowser wb = new WebBrowser(); wb.AllowNavigation = true; wb.Navigate("http://www.google.com/"); When examining the web browser's state via Intellisense after Navigate() runs, the WebBrowser.ReadyState is 'Uninitialized', WebBrowser.Document = null, and it overall appears completely unaffected by my call. On a contextual note, I'm running this control outside of a Windows form object: I do not need to load a window or actually look at the page. Requirements dictate the need to simply execute the page's JavaScript and examine the resultant HTML. Any suggestions are greatly appreciated, thanks!

  • Jquery.get() not returning any data

    - by David Waters
    Hi I am trying to scrape other people web pages (for the forces of good not evil). I am currently trying to do this with javascript/jquery from with in a browser. I am finding that the no data is returned from the jquery.get() success call back function. My code. $.get('http://www.google.co.uk/', function (data, textStatus, XMLHttpRequest){ alert("status " + textStatus); alert('data:' + data); window.data=data; window.textStatus=textStatus; window.httpReq = XMLHttpRequest}); In my mind this should simply do a get on google store the data in window.data and we are all good. What happens is we get textStatus == success and data == "". the status on the XMLHttpRequest is 4(success). I have looked at the network traffic using a transparent proxy (Charles) and everything looks find there http status 200 plenty of data being returned. I am running this just from the Firebug console in Firefox. Any ideas?

  • How to programmatically show & hide BalloonPopupExtender?

    - by Danferd
    I have a page that will be having few buttons that will redirect user to certain pages that required them to login before to proceed to the page. I would like to have something like, when user click on the button that required login and if user is not logged in prior to the click, a tooltip will show up beside the 'User ID' textbox to inform user to login in order to proceed. So, I implemented the jQuery Tooltipster in the page to show the tooltip message. I'm having problem on IE8 in Windows XP where the first click on the button, the tooltip would show up, but the second click it wouldn't then the third click, it shows up again and then the fourth click, it wouldn't! But for IE8 in Windows 7, IE9 & IE10, they have no such problem. Any idea how to fix this? The 'imgBtnKISS' & 'lnkBtnKISS' buttons are located in a content page but the tooltip and the 'User ID' textbox are in a master page. Below is the code that how I call the tooltip: function loginAlertMsg() { $('.tooltip').tooltipster({ trigger: 'custom', position: 'left', onlyOne: false, content: 'Login required! Please login to proceed.' }); $('#ctl00_txtID').tooltipster('show'); $('#ctl00_txtID').focus(); } Private Sub KISS_Click() Handles imgBtnKISS.Click, lnkBtnKISS.Click If Not bIsRefresh Then '==Detect User Login Status== Session(sesClickFromIcon) = toKISS If Session(USR.sesLogin) Is Nothing Then '//User NOT LOGIN. If (Not Page.ClientScript.IsStartupScriptRegistered("loginAlertMsg")) Then Page.ClientScript.RegisterStartupScript(Me.GetType(), "loginAlertMsg", "loginAlertMsg();", True) End If Exit Sub Else If Trim(CType(Session.Item(USR.sesLogin), Boolean)) <> True Then '//User NOT LOGIN. If (Not Page.ClientScript.IsStartupScriptRegistered("loginAlertMsg")) Then Page.ClientScript.RegisterStartupScript(Me.GetType(), "loginAlertMsg", "loginAlertMsg();", True) End If Exit Sub End If End If '**Detect User Login Status** Response.Redirect("~/page2.aspx", False) Session.Remove(sesClickFromIcon) End If End Sub
