Using WIN32 APi function "GetVolumeNameForVolumeMountPointA"

Hi,

I want to use the win 32 API function GetVolumeNameForVolumeMountPointA in my qt application, but I get this compilation error:

Code:

---

error: 'GetVolumeNameForVolumeMountPointA' was not declared in this scope

---

WinBase.h and Windows.h are included both. What might be the problem?

Thanks

How is this question related to Qt?

Sorry, because of the vaque description of my problem.
I just want to know if it is principally possible to use WIN32 Api functions in Qt applications? Are there any restrictions regarding the used compiler ?

Qt application is normal C++ application so You can do this.

Can I also use it with the gcc compiler, which is available in qtCreator?

Why wouldn't it be possible? And yes, you can write your code in any code editor you like and you can be wearing a Linux t-shirt while writing Windows code, your Windows shouldn't explode in your face because of that.

GetVolumeNameForVolumeMountPointA is defined in winbase.h only on Windows 2003, XP or later. According to the comment in MinGW's windows.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

Values are documented here: http://msdn.microsoft.com/en-us/libr...=vs.85%29.aspx
Try:

Code:

---

#define WINVER 0x0501
#include <windows.h>

---

or put:

Code:

---

DEFINES += WINVER=0x0501

---

in your PRO file for a project-wide setting

Great, it works.

Thanks a lot.
