Actually in this context EXPORT is nothing as in
#define EXPORT
The reason being is that this code was actually migrated years ago from
16bit and so theres a lot of legacy defines going on around the place.

Actually, thats a typo !!

Which is what I get as well on my four different machines.

Thanks I will download it and give it a whirl.

I am using Visual Studio 97 for this application. The SDK is old but I still
have users using Win95 for some applications (yeah I know - cheapskates - I
even offered them free upgrades to 98SE but they didn't go for it). Anyway
thats why I haven't upgraded as yet.

I looked into that I don't have OFN_NT4 (or whatever it is) in my headers
and will need to change the SDK. If I can definitely identify my development
environment as the problem then I'll change it, but I have to be sure first
before I resort to that. Your program will help out here because if it
crashes then I know its not me and if it doesn't then I know it is :-)

I have downloaded that SDK but I am not sure if it is compatible with VC5,
so I might even upgrade to VC6, just to make sure I keep current ;-)

Once again thanks for your time on this problem. I'll let you know tomorrow
how your program fared !! I will also do the same thing and ignore my
makefile and do it via the IDE as well (which i detest - I still use Brief
and the command line).

Leslie.
