• Windows Forms catching unhandled exception

  Hi, Is there any way I can catch unhandled exceptions in my application Actually, my application is multithreaded and uses a third party control. Once in a while, very randomly, an error occurs in one of the controls and no matter how many try catch I add, I am unable to trap the exception. Is there any class or function or any way at all that can enable my application to catch any unhandeled exception Thanks, Sorry, I am on framework 2.0 running VB 2005 beta 2.  That must be the difference. ...Show All

• Windows Forms VS 2005 (no beta). DataGridView. Problems with RowHeadersWidth and .ErrorText

  Hi ! I use VS 2005 (no beta).  I think I found a Bug in the DataGridView class.  I set the ErrorText property and could not see the red icon because I altered the RowHeadersWidth property. Then I comment this command and I could see the error icon and the error text on the row header again. It's amazing ! best regards, Joao Araujo this .dgrView.BorderStyle = BorderStyle .Fixed3D; // dgrView.RowHeadersWidth = 32; dgrView.MultiSelect = false ; dgrView.AllowUserToResizeRows = true ; dgrView.AllowUserToResizeColumns = true ; dgrView.AllowUserToAddRows = false ; dgrView.SelectionMode = Dat ...Show All

• Visual C++ passing arguments to a System(something.exe) function

  Background : I have an MFC application and a c++ program (separate entities). I did a build on the c++ program, and copy pasted the resultant 'exe' formed in its debug folder into the MFC application's folder. Now in the MFC, I am calling the function "System(mt.exe)", which is a call to the exe that I had copy pasted. Question : This exe (ie the c++ program) uses a variable 'counter' at some point in its execution. Is it possible for me to pass an 'int' as an argument to the exe when its called from the MFC, so that the 'counter' within the exe takes that passed integer as its value So effectively, first time the exe is executed, ...Show All

• Visual C++ Crash in destructor

  I'm using gtkmm 2.8.2 with Visual C++ 2005 Express to port a program from Linux to Windows. I'm using the win32 binaries from http://www.pcpm.ucl.ac.be/~gustin/win32_ports/ , which were apparently compiled with MSVC 2003, therefore I have to use the option /vd2 ( http://www.pcpm.ucl.ac.be/~gustin/win32_ports/ mentions this). Perhaps this causes my problem, but I don't know enough about the details of the C++ object layout that is used by MSVC. The problem is an access violation in a destructor. Anyway, here is an annotated disassembly of the destructor where the crash occurs: ; This is apparently just the usual prologue 00DC2600 pu ...Show All

• .NET Development catching an exception from an unmanged DLL

  Hi, within one of my DLL (using unmanged C++) I throw an exception of a user defined type (altenatively std::string - this caused the same result). In my .net solution that uses this DLL I've put everything into a try-catch block. The exception seems to be thrown correctly by the DLL, but the only thing my .net application receives is an exception of type System::Runtime::InteropServices::SEHException, accompanied by the message: "External component has thrown an exception." Does anyone know how this is done right Will it work at all Thanks, these blogs were really interessting - I think I should have a loo ...Show All

• Smart Device Development Dll can't work on real device!

  I built a Dll that can work correctly on SP2003 SE emulator, but when I deploy it to real device(dopod 585), the phone doesn't load the Dll. I noticed that the function calling sequence is : ProcessInit ThreadInit ProcessUninit ThreadUninit It seems to return immediately,  other exported functions doesn't work at all. I signed the Dll using "Smartphone 2003 Priviliged Test Signing Authority".  So what's wrong Please tell me how to handle differences between emulator and devices!. Thanks! Since your DllMain code got called, it is not a signing issue (or your DLL would not be permitted to execute an ...Show All

• Windows Forms designer can't load form. Where is 'more information'?

  after going from beta2 to rc1, the designer all of a sudden cannot load my forms anymore. instead, i get the infamous window with the red top that says some errors may go away building the project, while other need code changes. needles to say: the file compiles fine, the form could be opened with the beta2 and vs2003 designers and obviously doing a rebuild doesn't help at all. now what the additional error message says; Unable to load one or more of the requested types. Retrieve the LoaderExceptions property for more information. ok - great. now how do i retrieve the loader exception property. how can i fix this where can i find more info ...Show All

• SQL Server Extracting month, day, year from dates

  I need help in building a Select statement for an ODBC connection to an AS400 DB2 system. I am using this Select statement for SQL Reporting Services.
