How use "throw" in try except block

drjackool 956

Hi
I using following code:

void foo() throw(...)
{

    EXCEPTION_RECORD _ER;
    __try
    {
            if (some condition)
                AfxThrowMemoryException();
    }
    __except(GetExceptionRecord(GetExceptionInformation(), &_ER), EXCEPTION_EXECUTE_HANDLER)
    {
        // do some thing
    }
}

in function calling:

TRY
{
     foo();
}
CATCH_ALL(e)
{
  e->report();
}
END_CATCH_ALL

My problem is when throwing some exception the __except block executed instead outer try catch block

Thanks

MSVC implements C++ exceptions internally as a structured exception with a specific code (which I don't remember, but should be easy to determine experimentally). If you want to let it through, you need to check for that code and return EXCEPTION_CONTINUE_SEARCH.

You can see MSDN doc : try, throw, and catch Statements (C++)
And from try-except statementt :

"For C++ programs, we recommend you use native C++ exception-handling: try, catch, and throw statements."
