/EHsc enables standard exceptions. It does say nothing about the proprietary form.
Also, MSDN clearly states
"The two exception handling models, synchronous and asynchronous, are fully compatible and can be mixed in the same application."
under the topic "Exception Handling: Default Synchronous Exception Model"
Let's think the unthinkable, let's do the undoable, let's prepare to grapple with the ineffable itself, and see if we may not eff it after all.

Thanks jhwurmbach,
1. You mean in the current part of the application, which handles C++ exception;
2. The current part of application invokes another model, which throws structured exception to the current part;
3. The current part of application uses set_se_translator to convert structured exception to C++ exception and catch it (since current model is designed to handle only C++ exception).
Is my description correct?
If yes, my confusion is in the project setting, we could either select /EHa or /EHsc, means only one model could be selected, and how to make the current part and the other model in my sample above to have different exception model?
regards,
George

Please read the configuration settings again!
Enable C++ Exceptions:
1: No
2: Yes (/EHsc)
3: Yes with SEH Exceptions (/EHa)

Sorry Maxwell,
I think it is my mistake. 
The important point should be,
Maxwell Chen wrote: 3: Yes with SEH Exceptions (/EHa) // Standard C++ way plus SEH.
which means enable both structured exception and C++ exception, right?
regards,
George

Yes.
You can create a small test project and test both ways mixed.

Thanks Maxwell,
1.
So, set_se_handler works only in /EHa mode, since in /EHsc, there is no structured exception, so no need to convert, right?
2.
Maxwell Chen wrote: test both ways mixed
Confused about what do you mean both ways. In my current understanding, only /EHa mixed structured and C++ exception. /EHsc only produces C++ exception -- no mix. Correct me if I am wrong.

You were asking if the SEH model is compatible with the Standard C++ Exception model. You have already got the answer to your question. The SEH model and the Standard C++ Exception model can exist together in one single project. And you know the syntaxes of both models. I suggest you to launch your VC++ IDE, and test it yourself.

Thanks Maxwell!
Sorry I have not made myself understood. I just want to make a summary of this question and let you have a final review to see whether it is correct.
1. set_se_translator only works for /EHa mode;
2. in /EHsc mode, when there are programming errors, like dereferencing a NULL pointer, structured exception will not occur and program will report error and let end user select to debug;
3. /EHa mode is more accurately a mixed mode of structured exception and C++ exception, not structured exception only, as quoted from Visual Studio 2008
Enable C++ Exceptions Yes With SEH Exceptions (/EHa)

George

Do u want it to be open in the notepad editor or wanna get its handle?
Come online at:-
jubinc@skype
|
|
|
|
|
|
Then u can do the following:-
1. Use fopen(): It is a CRT function.<br />
2. Use CreateFile (): It is a Win32 API

Hi
here is my code
CDedJed d(this); //passes through constructor and member functions as well
d.Domodal(); // goes into the windows files wincore.cpp dlgcore.cpp dbgrpt.cpp
gives out debug assert error at the following lcation
->!::PeekMessage(pMsg, NULL, NULL, NULL, PM_NOREMOVE)
-> VERIFY(RunModalLoop(dwFlags) == m_nModalResult);
-> domodal();
FYI: resource IDs which are loading properly..checked with resource.h
help on this regard

Debug more into the RunModalLoop(dwFlags) function.
Come online at:-

thanks for ur reply i use gtalk, got no skype setup/accnt.
iam online urneel@gmail.com
FYI: This error occur only in debug mode but not in release mode.
here is debug details
VERIFY(RunModalLoop(dwFlags) == m_nModalResult);
ASSERT(ContinueModal());
// pump message, but quit on WM_QUIT
if (!AfxPumpMessage())
{
AfxPostQuitMessage(0);
return -1;
}
BOOL AFXAPI AfxPumpMessage()
{
CWinThread *pThread = AfxGetThread();
if( pThread )
return pThread->PumpMessage(); // here i end up with debug assert error
else
return AfxInternalPumpMessage();
}
regards

Comment out OnWindowPosChanged(). What happens in OnInitDialog()?

I removed windowpos function , Oninit function has local variables initialization nothing other than that.
FYI:
I found all reource IDs have been duplicated from other workspace to current work space and trying to display the dialog. could this be a probelm ?

What does it look like?

I suspected that until you showed that DoDataExchange() was empty.

No resource is not causing the problem...
what could be the case which asserts in debug but no in release???
my work fully stopped with this bug.

Assertions do not exist in Release mode.
