weird compile errors

ok I am getting a strange compile error:

  
// check for incoming messages

while( TestAPI.PeekMessage() != BFALSE )
{
//code here

}

I am getting the following error messages on the first line: d:\cotdb\netapi\conmestest.cpp(101) : error C2143: syntax error : missing '')'' before '';'' d:\cotdb\netapi\conmestest.cpp(101) : error C2059: syntax error : '')'' PeekMessage should return a unsigned char and BFALSE is #def to 0 and BTRUE to 1. Any ideas anyone? The project also uses STL and someone I know said that sometimes causes weird errors but I don''t know where to even start looking for STL induced errors as I am still pretty new to it...

Is there a ; in your BFALSE #define? If so, remove it.

yes there is, how did you know that was causing it? And why does it cause the problem?

Thanks for that by the way, I would have spent ages chasing it!

# means precompiler, #define means that the #define-d token will be replaced by whatever is on the #define line after it, *Before* the compiler runs. Look:
#define D true;

if(x==D)
...
becomes
if(x==true ; )

then the compiler reads it and doesn't like it.

Yep, I sometimes type the ; out of habit. I usually catch the mistake before hitting "build" though :-)
