.NET Forum / Languages / Managed C++ / January 2005Exception when using delayload linker option in release build
I have a VC++6 project where I need to delay load a DLL. I used a structured exception handling frame and all seems to work when I build the debug version and run it (either in or out of the debugger). In debug build, the exception is caught and reported gracefully to the user. When I build the release version and run it, the SEH frame does not catch the exception and the application crashes. Has anyone had a similar experience and if so, what is the resolution? >I have a VC++6 project where I need to delay load a DLL.

If it does not fix the problem, as Emily Litella used to say "nevermind". If it does it is because the Release build optimizes away your exception handling. That can happen when it doesn't see a way in which an exception can be thrown. Realize that the compiler has limited information when it does this - it does not know about structured exceptions, it only knows about C++ exceptions.

Have you tried changing the exception-handling compiler option for the file from /GX (implies /EHsc) to /EHa?  SignatureDoug Harrison Microsoft MVP - Visual C++ Thank you both very much, that seems to have solved the problem.
