Post by: earthquake on June 11, 2010, 04:24:16 pm

What is the value of WINVER ?
MinGW defaults to a low value if it is not set by user/program.

From windef.h

Code

#ifndef WINVER
#define WINVER 0x0400
/*
 * If you need Win32 API features newer the Win95 and WinNT then you must
 * define WINVER before including windows.h or any other method of including
 * the windef.h header.
 */
#endif

#define Windows95    0x0400
#define Windows98    0x0410
#define WindowsME    0x0500

/* Use these values to set _WIN32_WINNT and WINVER to your mimimum support

#define WindowsNT4   0x0400
#define Windows2000  0x0500
#define WindowsXP    0x0501
#define Windows2003  0x0502
#define WindowsVista 0x0600

I suggest using the value that is nearest to your system.

By the way that's far beyond the scope of this forum.
