How to catch a dll exception [message #28925]

Hello all

Running a dll I get this exception:

EXCEPTION_FLT_INVALID_OPERATION

Is it a way to catch these exceptions properly?

I have tried with __try __finally but it does not serve.

Best regards
Iñaki

Hello Massimo

It seems C++ exceptions and Win32 and hardware exceptions are not the same.

Now I am reading about SEH exceptions ("Structured Exception Handling").

Best regards

SEH should be for C exception, try...catch for c++ ones, and (IIRC) they're not very compatible.
If your DLL throws c++ exception, they should be caught with try... catch construct; if it's a c dll, it should work with SEH.

If both don't work, I'm out of ideas Smile
