  • Win32 Thread Exits Unexpectedly

    - by sahs
    Hello, I'm writing a C++ application. I realized that one of my worker threads may terminate unexpectedly. The (VS 2005) debug log says: The thread 'Win32 Thread' (0x5d98) has exited with code -858993460 (0xcccccccc). I surrounded all the worker thread code with a try/catch block. So, if the reason was an exception, I would catch it. But I can't: try{ ... Connection* conn = connectionPool->getConnection(); // unexpected exit occurs here ... } catch(exception& e) { ... } I have ten threads running concurrently, and only one of them gets crashed after some time, while the others continue running (and getting new [OCCI] connections). Is there an exception type that is not caught by "exception"? Or what do I not know about threads/exceptions? Thanks.

  • How to read log4j output to a web page?

    - by Ran
    I have a web page, used for admin purposes, which runs a task (image fetching from a remote site). In order to be able to debug the task using the browser only, no ssh etc, I'd like to be able to read all log output from the executing thread and spit it out to the web page. The task boils down to: Changing log level for current thread at the beginning of the call and restore when the call is done. Reading all log output by current thread and storing it in a string. So in pseudocode my execute() method would look like this: (I'm using struts2) public String execute() throws Exception { turnLoggingLevelToDebugOnlyForThisThread() ... do stuff... restoreLoggingLevelForThisThread() String logs = readAllLogsByThisThread(); } Can this be done with log4j? I'm using tomcat, struts2, log4j and slf4j.

  • Self hosted WCF console output from service

    - by user989056
    quick one: Is it possible to capture the output stream of a WCF service that is hosted via ServiceHost ( self hosted service) ? I have methods within my WCF service that output useful debugging information, is it possible to send these to it's host's console output? Edit: It appears that I have made an obvious blunder - I was using Debug instead of Console. It is possible to output to the console by using the standard Console output commands in your WCF service class. I have marked the answer that I have found the most useful.

  • GridView in UpdatePanel adds extra rows when sorting another grid

    - by chopps
    Hey Everyone, I'm a seeing some weird behavior that i have never seen before. I have two grid in separate UpdatePanels. I can page and sort each without any problems. Each grid is set for 10 per page. If the first grid (13 records) is paged to the second page and then i go down to the second grid (14 records) and page to the next page and the first grid adds a bunch of empty rows to the grid so it is full to show 10. There is no data in the rows...just empty rows. Each grid does this on paging and sorting. Ive stepped through the code and the the loading of the other grids never happens so it tells my AJAX is doing something to add the 'phantom' rows to the grid. Any ideas why or ways to debug this?

  • Allowing developer-specific settings in VS2008 projects

    - by Xavier Nodet
    Is it possible to combine the following properties, and if so, how? Store in our version control system some Visual Studio 2008 native C++ project files for the developers in our team that use this IDE. Allow some of those developers to tweak their projects (e.g. using debug version of third-party libraries instead of the usual ones). Make sure these modifications are done in files that are not versioned. In other words, I would like to allow developers to tweak some settings in their projects without risking that these changes are committed. An 'optional VSPROP' file approach seems doomed to fail, as VS2008 refuses to load projects that refer to non-existent VSPROP files... Any other suggestion? Is this possible with VS2010?

  • Regex problem ...

    - by carlos
    hello i have the next regex Dim origen As String = " /c /p:""c:\mis doc umentos\mis imagenes construida\archivo.txt"" /cid:45 423 /z:65 /a:23 /m:39 /t:45rt " Dim str As String = "(^|\s)/p:""\w:(\\(\w+[\s]*\w+)+)+\\\w+.\w+""(\s|$)" Dim ar As Integer Dim getfile As New Regex(str) Dim mgetfile As MatchCollection = getfile.Matches(origen) ar = mgetfile.Count When i evaluate this it works, and gets the /p:""c:\mis doc umentos\mis imagenes construida\archivo.txt"" that basically is the path to a file. But if I change the origen string to Dim origen As String = " /c /p:""c:\mis doc umentos\mis imagenes construida\archivo.txt""/cid:45 423 /z:65 /a:23 /m:39 /t:45rt " Check that the end of the file is follow by "/cid:45" whitchs makes de patter invalid, but insted of getting a mgetfile.count = 0 the program is block, if i make a debug I got a property evaluation failed. Thanks for your comments !!!

    I'm using Visual Studio 2008 C++ and working on a dll project. Debug compiled and linked perfectly but when I compile the release version, it shows this: VImgPtr.obj : error LNK2001: unresolved external symbol @__security_check_cookie@4 VLibraryPtr.obj : error LNK2001: unresolved external symbol "void __cdecl operator delete[](void *)" (??_V@YAXPAX@Z) D:\Source Code\VImgLib\Release-vc9u\VImgLib-vc9u.dll : fatal error LNK1120: 2 unresolved externals If I selected Multi-threaded (/MT) in "C/C++-Code Generation tab), it linked ok. The problem is only when I choose Multi-threaded DLL (/MD). I'm releasing a dll, so should be /MD right?

  • jQuery, ajax request doesn't success with JSON on IE

    - by sylouuu
    I made an AJAX call and it works on FF & Chrome but not on IE 7-8-9. I'm loading a JSON file from my domain: $.ajax({ url: 'js/jquery.desobbcode.json', dataType: 'json', cache: false, success: function(json) { alert('ok'); }, error: function(xhr, errorString, exception) { alert("xhr.status="+xhr.status+" error="+errorString+" exception="+exception); } }); I also tried by adding contentType: 'application/json' but I receive the same output which is : xhr.status=200 error=parsererror exception=SyntaxError Unterminated string constant I checked my JSON file with JSONLint and it's OK. I checked if there is an extra comma and the content is also trimmed. See my JSON file If I put dataType: 'text', I receive the OK alert but a debug popup too. Could you help me? Regards.

  • How to ensure that you are building against STLport.

    - by Pradyot
    I am using Visual C++ 2005 to build a couple of libraries and an executable. I include the STLport location in the Additional Include Path of the libraries and include the library in the input to linker for executable. The library however seems to reffer to stl symbols (such as string) without the stl port namespace. This results in a linker error. these are the relevant lines from the command line on the 2 libraries and executable: /Od /I "..\Junctions\fo_fid_3rdParty\STLport-5.1.0\stlport" /Od /I "..\Junctions\Includes\fo_fid_3rdParty\STLport-5.1.0\stlport" /OUT:"..\ET_BUILD\vc8\Debug\bin\SFGWDealerwebFixAutorecD.exe" /INCREMENTAL:NO /NOLOGO ..\junctions\libs\fo_fid_3rdParty\STLport-5.1.0\lib\stlportstld_vc8.5.1.lib thanks

  • InfoPath browser form submitting dirty fields changed through javascript

    - by Xavier
    I'm trying to submit an InfoPath browser form with fields that have been modified through the Spell Checker included in Sharepoint server. The spell checker checks all the fields in the page and once the user closes the SpellChecker dialog, it changes the textboxes with the new values through javascript. When I click Submit, debug the FormEvents_Submit in the form code behind and try to do a GetNodeValue("XPath to changed field"), it still shows the old values. I realize that this may be a problem of doing postbacks and I'd like to do a full page postback once the SpellChecker is done changing all the textboxes. Any suggestions would be appreciated. Thanks.

  • WCF: Callback is not asynchronous

    - by Aquarius
    Hi, I'm trying to program a client server based on the callback infrastructure provided by WCF but it isn't working asynchronously. My client connects to the server calling a login method, where I save the clients callback channel by doing MyCallback callback = OperationContext.Current.GetCallbackChannel() After that the server does some processing and uses the callback object to communicate with the client. All this works, the problem resides on the fact that even though I've set the method in the OperationContract as IsOneWay=true, the server still hangs when doing the call to the client. I've tested this by launching the server for debug in the visual studio, detaching it, launching the client, calling the above mentioned login method, putting a break point in the implemented callback method of the client, and making the server send a response to the client. The server stops doing what it's supposed to do, waiting for the response of the client. Any help is appreciated.

  • Object reference not set to an instance of an object - how to find the offending object name in the

    - by Jason
    This is the bane of my programming existence. After deploying an application, when this error crops up, no amount of debug dump tells you WHAT object was not instantiated. I have the call stack, that's great, it tells me roughly where the object is, but is there any way to get .NET to tell me the actual name of the object? If you catch them while debugging, of course the program breaks right on the offending creature, but if it happens after the program is in the wild, good luck. There has to be a way. I've explored the exceptions returned in these instances and there is just nothing helpful.

  • IIS Active Directory double handshake hickup

    - by AngryHacker
    I have a .net 2.0 click-once application that connects to IIS web services on Windows 2003 R2 64-bits. The IIS is setup with Integrated Windows Authentication. So whenever a web service call is made to IIS web services, there is a double handshake taking place: Client Request #1 GetEmployeeList Server Response #1 <- 401 HTTP/1.1 401 Unauthorized WWW-Authenticate: Negotiate WWW-Authenticate: NTLM Client Request #2 REQUEST Header... Server Response #2 <- 200 Data Received Lately, however, Server Response #1 will sometimes (a good 20 percent of the calls) take a massive amount of time (like 25 to 30 seconds). How do I debug this problem? Is this a Active Directory problem or a Domain Controller problem?

  • Getting exc_bad_access error only when mallocguard is enabled

    - by Nareshkumar
    I have an app for iPhone in development which works properly when the Malloc guard is not enabled. However when i try to enable the malloc guard i get the following error after the app is loaded. #0 0x95f65684 in objc_msgSend () #1 0x30506515 in NSPopAutoreleasePool () #2 0x30901697 in _UIApplicationHandleEvent () #3 0x32046375 in PurpleEventCallback () #4 0x30245560 in CFRunLoopRunSpecific () #5 0x30244628 in CFRunLoopRunInMode () #6 0x308f930d in -[UIApplication _run] () #7 0x309021ee in UIApplicationMain () Now my problem is that i am not able to debug the exact location where its getting the error.. have tried malloc_error_break but didnt work out. Is it that malloc guard enabling auto releases some of the objects based on allocation??

    Hello, I write a little Tool in C# with Visual Studio 2008. My Problem: I login to a website by HTTP-webrequest, I get an authentification cookie, thats all ok. Than I make a new HTTP-webrequest and add the cookies from the first request to call the next page where i can see my personal data.

I tried many possibilities to see why i dont work but i found nothing. Does somebody have the same problem or know a solution? (Sorry for bad english)

  • why this assembly program is loaded from the address 0B3D:0000?

    - by viperchaos
    I have seen a assembly program written from a book about assemble: assume cs:code code segment dw 0123h,0456h,0789h,0abch,0defh,0fedh,0cbah,0987h mov bx,0 mov ax,0 mov cx,8 s: add ax,cs:[bx] add bx,2 loop s mov ax,4c00h int 21h code ends end This program's function is to add eight numbers. The author compiled this program in the DOS and use the DEBUG to see how this program be loaded. The author use the R command and got that DS = 0B2DH ES = 0B2D SS = 0B3D CS = 0B3D IP = 0000 And then the author said that this program is loaded from the address 0B3D:0000. I'm a confused that why this program is loaded from the address 0B3D:0000? Is this because the existence of the Program Segment Prefix(PSP)? If the answer is the existence of the PSP, what is in the PSP?

  • How can I get Syslogging to work on the JVM?

    - by Synesso
    I want to do syslogging from Java. There is a log4j appender, but it doesn't seem to work (for me anyway ... though Google results show many others with this issue still unresolved). I'm trying to debug the appender, so I've written the following script based upon RFC3164 It runs, but no logging appears in the syslog. // scala import java.io._ import java.net._ val ds = new DatagramSocket() val fullMsg = "<11>May 26 14:47:22 Hello World" val packet = new DatagramPacket(fullMsg.getBytes("UTF-8"), fullMsg.length, InetAddress.getLocalHost, 514) ds send packet ds.close I also tried using /bin/nc, but it doesn't work either. echo "<14>May 26 15:23:83 Hello world" > nc -u localhost 514 The Ubuntu command /usr/bin/logger does work, however. logger -p user.info hello world # logs: May 26 15:25:10 dsupport2 jem: hello world What could I be doing wrong?

  • Google Calendar title displayed incorrectly

    - by Don
    Hi, I'm creating 2 Google calendars via the Java client API using the following Groovy method: private CalendarEntry createGoogleCalendar(User user) throws ServiceException { new CalendarEntry().with {calendar -> title = new PlainTextConstruct(user.email) summary = new PlainTextConstruct("Collection calendar for $user.email") timeZone = new TimeZoneProperty("America/Montreal") hidden = HiddenProperty.FALSE def savedCalendar = googleCalendar.insert(CALENDAR_URL, calendar) log.debug "Created calendar with title '$savedCalendar.title.plainText' for '$user.email'" return savedCalendar } } The logs show: CalendarService - Created calendar with title '[email protected]' for '[email protected]' CalendarService - Created calendar with title '[email protected]' for '[email protected]' so it appears that all is well. However when I look at the 1st calendar on the Google website, the title is shown as [email protected], though the summary is correctly shown as Collection calendar for [email protected]. Strangely, the title and summary are both shown correctly tor the 2nd calendar. This only started happening today, and I'm pretty sure the relevant code has not changed. I'm totally stumped....

  • C++ program runs slow in VS2008

    - by Nima
    I have a program written in C++, that opens a binary file(test.bin), reads it object by object, and puts each object into a new file (it opens the new file, writes into it(append), and closes it). I use fopen/fclose, fread and fwrite. test.bin contains 20,000 objects. This program runs under linux with g++ in 1 sec but in VS2008 in debug/release mode in 1min! There are reasons why I don't do them in batches or don't keep them in memory or any other kind of optimizations. I just wonder why it is that much slow under windows. Thanks,

The realm is configured as such <Realm className="org.apache.catalina.realm.JNDIRealm" debug="99" referrals="follow" connectionURL="<url>" connectionName="CN=Query Account,OU=Service Accounts,DC=company,DC=com" connectionPassword="<pwd>" userBase="OU=Users,DC=company,DC=com" userSubtree="true" userSearch="(sAMAccountName={0})" userRoleName="member" roleBase="OU=Security Groups,DC=company,DC=com" roleName="cn" roleSearch="(member={0})" roleSubtree="true"/> Our groups in AD are such Security Groups (OU) IT (OU) IT Support (OU) Support Staff (CN) The LDAP security works if in the web.xml, I speficy Support Staff. i.e works for Common names. We want ANY user under Security Groups OU to have access to the application and not just the CN. Tomcat does not search OU's and it just searches CN's in our case. How do we configure our settings so we can do OU level authorization and not just CN level ? thanks Mat

  • WPF application in obj directory doesn't work.

    - by juharr
    When I build my WPF application the exe that ends up in the bin directory works just fine, but the one in the obj directory does not. When I Debug the exe from the obj directory I get the following exception: TypeInitializationException was unhandled: The type initializer for 'MyProject.App' threw an exception. So basically I'm wondering why the obj exe doesn't work while the bin one does (I was under the assumption that the obj exe was just copied to the bin) and how to fix it. The reason that I even care is because I'm using Wix to create a MSI for my application and I have a Votive project setup that uses var.MyProject.TargetPath which points to the exe in the obj directory.

  • How to shutdown local tomcat server when closing browser window?

    - by agez
    Hi, I hava a web app running on a local tomcat server. When the user starts the app (via desktop shortcut) the server starts and the app is opened in a browser window. But when the user just clicks on the close button to stop the application the server is still running in the background - that's annoying. I tried to utilize the "unonload" and "onbeforeunload" events from javascript but unfortunately these events are also fired on some other requests in the app. So I can't use them, except I do a lot of refactoring. Does anyone have an idea for a possible solution? Btw, what I find interesting is the behaviour of Visual Studio when debugging a web application. When I close the browser window Visual Studio also gets a trigger to stop debug mode. So it seems it somehow notices the close event of the browser window, which would be exactly what I need. But I don't know how they do it... Cheers, Helmut
