Can i export visual C++ program to and from win 95 to 98 or NT or vice versa?
Is there any website that give detailed information on this portability issue?

No website will give as much info about Visual this and Visual that as much as Microsoft's MSDN....

As my experience, a few programmes that used lib's specific to win 2000 did not work on win 89. even when I copied the dlls...

The text2speech lib wa my problem giver...

All the best.

I did actually experienced huge problem in converting a program from 98 to 2000. It was CreateFile that gave me problems. dwFlagsAndAttributes must be set to NULL anything else could give problems from read and write to com port.

HANDLE CreateFile(
LPCTSTR lpFileName, // pointer to name of the file
DWORD dwDesiredAccess, // access (read-write) mode
DWORD dwShareMode, // share mode
LPSECURITY_ATTRIBUTES lpSecurityAttributes,
DWORD dwCreationDisposition, // how to create
DWORD dwFlagsAndAttributes, // file attributes
HANDLE hTemplateFile // handle to file with attributes to
);

I guess this link is the closest you get to see if the function exist in the operating system you are working on.
