#include <mmsystem.h> and DWORD ?

[nthung]

this is my code

#include <QtCore/QCoreApplication>
#include <mmsystem.h>
int main(int argc, char *argv[])
{
QCoreApplication a(argc, argv);
DWORD what;
return a.exec();
}

but it gives me an error"DWORD is not a type name" why is wrong?
thanks

DWORD is defined in windows.h so #include <windows.h> should do the trick

[high_flyer]

but bare in mind that using DWORD will make your code non portable!
Better use either 'unsigned long' or better yet, Qt types, such as quint32 etc.

@high_flyer: Correct, but maybe he has some already written code with DWORD.

But if only DWORD is "missing" you can get away without include windows.h, just typedef DWORD like this:

typedef unsigned long DWORD;
