You need to capture more information in your catch block, or use the debugger to trap it and see what is going on in the CallFunction() method; perhaps the parameter is incorrect.

I was unsure what type of error it was throwing so I used ... in catch block. Debugger is not able to help here. By debugging, I have checked for the expiry of the flash object but it was alive so no problem there. Even parameters are also right.

I think Andrew has made some useful suggestions above. You need to display the actual error code in your catch block; in your case you are just printing a rather unhelpful message.

This CallFunction is inside flash9c.tli file. Whenever I write any helpful statement there and compiles the code then it automatically reverts back. I am not able to put any statement there. I think this file generates automatically at compile time.

I have no experience of Flash, so I am unable to make any further suggestions.

Hi everyone! I had the following lines of C++ code in my program
CFileDialog dialog(true);
CString strFileName=L"";
INT_PTR nResult = dialog.DoModal();
if(nResult == IDOK)
strFileName=dialog.GetFolderPath();
The problem is: When I execute the program on a PC running Windows XP, there always have an ugly exception which I don't know why it happened. But everything's fine when I copied it to another PC running Windows 7.
I'm desperate. Would you guy please tell me why?

The hWnd=0x00000000 is probably due to clean-up code.
As for the exception, could you tell us what it is. What code and/or message.
If you go to Debug>Exceptions and tick everything, it should break the debugger the moment the exception is thrown, so you can see what is causing it.
Once you have found the source, reset the exceptions filter (there should be a Reset All button in the dialog) otherwise they will annoy the heck out of you

MSDN[^] says:
The dialog box must have been created with the OFN_EXPLORER style; otherwise, the method will fail with an assertion.
You need to create the dialog like
CFileDialog dialog(true, NULL, NULL, OFN_HIDEREADONLY | OFN_OVERWRITEPROMPT | OFN_EXPLORER);
|
|
|
|
|
Sorry! It doesn't work.

Perhaps i should have read the next line on that page[^].
"You can call this method only while the dialog box is being displayed. After the dialog box has been closed, this function will no longer work, and the method will fail with an assertion."
Not sure why it works on Windows 7, but you can instead use
strFileName = dialog.GetPathName();
strFileName = strFileName.Left(strFileName.ReverseFind(_T('\\')) + 1);
That is just example code, and you should add error checking into it to ensure there is a '\' character

 Yeah! You're right! I should read MSDN carefully before asking this question. Anyway, thank you so much!

Hello debug experts.
<b></b>I'll fess-up before I get flamed by someone here..
I did posted this in OpenCV group without success.
<b></b>This is basic dll debugging process I do not know how to do.
I need to debug , step thru, OpenCV function and I just cannot figure out the mechanics.
I put cv dll (dsp) as main project and then I added my application to the workspace.
I set a break point at the cv function entry in my application and then execute the cv dll.
However, I just cannot step into the cv dll function to check the code progress.
F11 goes right over the function.
What bugs me is that I can step thru other OpenCV code (Haar training) without a problem!
Can it be done and dhow ??
What am I missing??
Using VC6.0 , both - dll and my app - are configured for debug. No compiler or linker errors.
My app is linked to the debug library of the cv dll.
The application runs, sort of - bogus Haar objects are being detected.
Thanks for you help, it is as always appreciated.
Cheers Vaclav

Try rebuilding the complete project (application and DLL) in Debug mode and see if that works.

Richard,
found out that the function I am after is not in cv but in cvaux.
Added all relevant libraries and dependencies, rebuild all with success.
Still no go.
The question is - do I need to link the correct debug libraries?
Right now I have a mix of release and debug.
I'll do that next anyway.
What about the preprocessor's NDEBUG #define?
The functions I can step thru are in debug libaries and have the NDEBUG defined.
Thanks
Vaclav

Richard,
noticed difference between project settings - the one which works has a "Link" tab option and the one which does not work - cvaux has a tab "library". No Link.
They both have _DEBUG in various places , no more NDEBUG.
Vaclav
PS Here are the library links. Both are set for debug option and cvhaartraining lets me step thru and the cvaux (both cvaux or cvaud) won't do it.
#pragma comment(lib,"G:\\Program Files\\OpenCV\\lib\\cvhaartraining")
#pragma comment(lib,"G:\\Program Files\\OpenCV\\lib\\cvauxd")
Thanks for helping me. I am stuck!

I can only assume that the cvauxd library should be a Debug build. You need to recheck all the project settings (Compiler and Library tabs) to ensure that they are creating all the Debug information required.

Yes, OpenCV designates debug libraies wiht suffix "d". Clever but I had to ask!
I think I need to check if these libraries are the ones I am actually linking to.
Right now I chaged to cxcored and getting this error which I totally do not know how to troubleshoot.
HEAP[Open....exe]: Invalid Address specified to RtlValidateHeap( 1e20000, b570450 )
What is realy strange this "cvhaartraining" dll compiles and builds a library without telleing me if it is debug or release.
I bet I am missing where it should go, but it works!
....
--------------------Configuration: cvhaartraining - Win32 Debug--------------------
Compiling...
cvboost.cpp
cvcommon.cpp
cvhaarclassifier.cpp
cvhaartraining.cpp
OpenMP not defined
cvsamples.cpp
Creating library...
--------------------Configuration: cv - Win32 Debug--------------------
.....
And that is the dll I can step thru!!!
And this is "normal" output
Generating Code...
Linking...
Creating library ../../lib/cvd.lib and object ../../lib/cvd.exp
I guess I'll go over all the options again!
Thanks for your input.

That is fairly normal. It is up to you to select the appropriate configuration to build and ensure that all the options are set correctly. As this is a third party product that I have never worked with I cannot make any better suggestions.

1. Make sure the debug configuration is selected. Debugging works in Release mode but not as good
2. Check which library you are linking against. It should be cvd.lib (the main part is that you are lining against XXXd.lib for the debug libraries
3. Check the project properties for the DLLs to make sure debugging information is getting generated. I don't know where this is in VC6, but in VC9 is is Project Properties>Linker>Debugging>Generate Debug Info
4. Insert a breakpoint early in your code for the .exe you are testing it with. the first line of main() would be a good place
5. Check the loaded modules (in VC9 it is Debug>Windows>Modules) and make sure the right versions of the DLLs are loaded in (XXXd.dll)

Hi all
I have two view ,Opengl and Live Video (Which convert live video data to image and show on CDC).
The 3D image draw in Opengl with different 3D point and draw in video CDC(convert 3D to 2D point).
Here My problem is how to draw 3D image in 2D live video CDC?.It should be show like OPengl with different shade,color,Blending and all feature which is provide by OpenGL.
AnyOne suggest the way for achive this thing.
Thanks

My application (32 bit) starts next process instance of itself. In new process I need to start debugging so I'm using __asm int 3; It worked good in WinXP/VS2008, it stopped the app and gave me selection whether start new VS instance or use existing VS instance to debug. I've switched to Win 7 64 bit and it does not work anymore. It offers nothing, app just hangs for some time, then exits, I cannot even attach debugger to the process manually. How can I solve this?
Thank you.
In VS options, the "Jst-in-time" I have all options active (managed,native,script)

try
#include "CrtDbg.h"
_CrtDbgBreak();
|
|
|
|
|
the same result
|
|
|
|
|
_CrtDbgBreak() is a valid function under Win64. Perhaps it expects a debugger to be attached.
Perhaps you could use something like:
while (!IsDebuggerPresent()) {
Sleep(1000);
}
It is quite a hack up, but if it is just for testing it doesn't really matter.
