timeGetTime

[Erik]

Hi,

I'm using VC.net making a DLL and trying to use functions in
MMSystem.h particularily timeGetTime().
I include "windows.h", "MMSystem.h" (just a precaution, it should be
enough with windows.h, right??) and add the WinMM.lib library but
still I get a compiler error (ie no linker error) saying that the
identifier cannot be found.

Another problem is that if I try to include a file that does not
exist, the compiler won't generate an error.... that should not be any
problem here though, the files above *do* exist.

Has anybody an idea what this could be?

Thanx!

/Erik

Maybe what this could be: Examine your stdafx.h file. If it contains a
#define that is anything like LEAN_AND_MEAN delete it. This #define
hides a lot of "less frequently used" portions of windows.h to speed
compiles.

Thanks Scott!
That might have been the reason. However, when I search for that file
in the vc install dir I come up with 35 results so I have a little
problem determining which one is used in my app ;-)
I happy now that it works for whatever reason anyway :-)

The stdafx.h file that your program uses is in your project directory,
not any of the VC directories.

Actually LEAN_AND_MEAN was not defined in the stdafx file that I
used.... It instead seems that it is defined in afxv_w32.h. If I
remove it there it works!
Seems a bit odd though, to have to edit that file....

I found the error myself, I had to recompile the precompiled headers
for some reason. Now it works!
