When i'm trying to compile a program in C++ I keep getting an error:

at the line

#include "dxfile.h" // defines LPDIRECTXFILEDATA

and the debugger says:

Do you have any idea?

Generally if you get a warning like "invalid conversion from 'x' to 'y' " then you are probably compiling something as c++ that might otherwise compile ok as C; in short, cast to the required type which is being complained about (eg. void* to HINSTANCE requires an explicit type cast to HINSTANCE).

The newline at end of file warning is common with gcc (g++); apparently it's now standard to have a newline at the end of each file so get into the habit of adding one to eliminate that annoying warning.

NULL is good for pointers only, not numbers, hence " NULL used for non-pointer argument". Zero works for numbers and pointers so, to avoid this hassle, just use zero for both ie zero for NULL pointer and as the numeral itself. If you prefer to continue to use NULL then remember to use it only with pointers.

"stray '\32' in program" - don't have a clue; that's a new one on me. However the compiler, as with all such errors\warnings, usually explicitly tells you where the problem occurs. So open up 'dxfile.h' and take a close look at (and possibly around) line 240 to see what the problem is.

Hope that helps some.

Sounds like the compiler does not recognize most of the declarations in the header file. This will produce oodles and oodle of warnings. Check to make sure that the header file is compatible with your compiler.

I switch to MSV C++ 6.0 and tried #include <ddraw.h> and this showed up:

Linking...
LIBCD.lib(crt0.obj) : error LNK2001: unresolved external symbol _main
Debug/DDrawtut.exe : fatal error LNK1120: 1 unresolved externals
Error executing link.exe.

DDrawtut.exe - 2 error(s), 0 warning(s)

help this is really annoying me, why isn't the SDK working correctly!

Are you linking the correct libraries?
Did you create a windows project, or a console app? (should be former)
