INVALID_SET_FILE_POINTER isn't declared anywhere...

[redeemer]

When i try to compile a program, VirtualDub actually (www.virtualdub.com), it says that INVALID_SET_FILE_POINTER is an unknown identifier. Accoring to MSDN it's defined in winbase.h (include windows.h) but when i search for that phrase (INVALID_SET_FILE_POINTER) in my include folder, no results are found. Anyone know what could be wrong? Thanks

I have found it in winbase.h #define INVALID_SET_FILE_POINTER ((DWORD)-1) but only in sdk downloaded from Microsoft. This define does not exist (on my computer) in both VC6.0 and VC7.0 include/src folders. Mukkie
