I get some exception error code in debug mode. "First-chance exception at 0x0055ca40 in Laby.exe: 0xC0000094: Integer division by zero." The first error is integer devision by zero. However, I explictly made my program catch all windows exception. And if I intentionally divide by zero it catchs it. Why it doesnt catch this devision by zero? And what "is exception at 0x0055ca40"? Thanks in advance. 'Laby.exe': Loaded 'E:\Projects\Engine2\V0\Laby\Debug\Laby.exe', Symbols loaded. 'Laby.exe': Loaded 'C:\WINDOWS\system32\ntdll.dll', No symbols loaded.

I didnt find where to enable SEH in visual 2003.
But I do have EHac enabled.
Why do I need the first and not the later?
My code for handling windows exceptions is:

static void se_translator (unsigned int e, PEXCEPTION_POINTERS p){	WindowsError WinErr;	WinErr.Ptr = p;	throw WinErr;}

It's all about the wheel.Never blindly trust technoligy.I love my internal organs.Real men don't shower.Quote:Original post by Toolmaker Quote:Original post by The C modest godHow is my improoved signature?It sucks, just like you.

Another thing I've found is that SIMD instructions do not raise floating point exceptions. If the complier is implementing you floating point code with SSE instructions they will not raise exceptions.

Also you may need to explictially turn on FP exceptions in your code with _controlfp (this is slow so should only be done in debug mode).

Edit: Actually I didn't read the OP properly I don't think these comments apply :)
