GIF showing problem
-
Hi all, I am trying to show single-frame/animated GIF images in a window created by 'CreateWindowEx'. I have used Image *, Graphics * (method DrawImage(Image *, INT, INT, INT, INT)) of GdiPlus dll. I used memry DC to avoid flickering. This was working fine. Now the problem is that - When I add 2 commands /DYNAMICBASE and /NXCOMPAT in linker command line (VS 2005 project settings), the application simply crashes when trying to show any kind of GIF image. Although it is showing BMP, DIB, WMF, JPG, JPEG and TIFF images perfectly. To see where the actual problem is i ran it in debug mode and find GdiPlus::Graphics::DrawImage fail to process. The Application Verifier 4.0 points that it is due to some bad address pointer. The astonishinig matter is that, in debug mode if I ignore the crash and click on 'Continue', the 'DrawImagw' returns StatusResult "Ok" and 'BitBilt' draws the image perfectly in my application window. Thanks in advance, for helping me out of this situation. Subha

Thanks for the suggesstion Xing. Since I am writting code in pur C++ and using Win32 APIs, I didn't found what is the exception class I should use to catch it. If you can suggest me, that'll be better for me.

Thanks Xing and Hamid, I even tried with try{ // My code snippet } catch(...) { ::Messagebox(0,0,0,0); } It does not enter in catch part. I am feeling sick of this:confused:
What was the error and did you use of your program on the vista?

Hi Hamid, Now, I find where the problem occurrs. It is nothing to do with the project setting /DYNAMICBASE or /NXCOMPAT in Linker command line. The application only crashes if I run it with Application Verifier 4.0. Otherwise it is able to show (DrawImage) any kind of GIF image. I am giving a part of the xml file generated by the Application Verifier 4.0. I hope it will help you to understand the error properly, which I could not resolve till now. <avrf:logEntry Time="2009-04-15 : 12:18:56" LayerName="Heaps" StopCode="0x13" Severity="Error"> avrf:messageFirst chance access violation for current stack trace.</avrf:message> avrf:parameter15960002 - Invalid address causing the exception.</avrf:parameter1> avrf:parameter24ed9b280 - Code address executing the invalid access.</avrf:parameter2> avrf:parameter3129838 - Exception record.</avrf:parameter3> avrf:parameter4129854 - Context record.</avrf:parameter4>

Did you use of this code on your code? __try { } __except( EXCEPTION_EXECUTE_HANDLER) { }

Hi Hamid and Xing, Many many thanks for your suggestion. I tried what both of you have said. But that was giving "error C2712: Cannot use __try in functions that require object unwinding" in my VS 2005. Anyway I solved that error by setting "Enable C++ Exceptions" to "No". Now I can track the exception, though generating too many warnings at compile time (for disabling C++ exceptions). So, the application doesn't crashes anymore. Anyway, I need to show the GIF images. So, how can I do that after getting that exception - EXCEPTION_EXECUTE_HANDLER. What should I do :(

Though i know, this is not a good approach, but here you can use this block to catch all the exception :-
try
{// your drawing code here
}
catch(...)

Hi Xing, Thanks for your enthuasism, what you and Hamid have shown to my problem. I used that __try-__exception() block. Inside that I call 'GetExceptionCode' API, which returns me the error code 0x80000003. It means EXCEPTION_BREAKPOINT (#define EXCEPTION_BREAKPOINT STATUS_BREAKPOINT in winbase.h). And in winnt.h STATUS_BREAKPOINT is defined as 0x80000003. So, right now I am here, back again in the square. I don't understand what is the problem with Application Verifier 4.0. Without tracking by it, the application works fine.
