c++ winform 不能调用获取屏幕分辨率函数GetSystemMetrics的问题

#include "windows.h"

#pragma comment(lib, "user32.lib")

int cx = GetSystemMetrics( SM_CXSCREEN );

int cy = GetSystemMetrics( SM_CYSCREEN );

参考MSDN资源如下：

I am trying to get the size of the button in Windows in my project using windows API GetSystemMetrics(SM_CXSIZE).

Whereas GetSystemMetrics(SM_CXSIZE) returns '36' in Windows 8 and I am able to adjust the tool bar window correctly. But it returns '22' in Windows Server 2012 and I am not able to adjust my tool bar properly.

A sample code snippet is:

#include <windows.h>
#include <stdio.h>
#pragma comment(lib, "user32.lib")

int main()
{
printf("Value SM_CXSIZE: %d", GetSystemMetrics(SM_CXSIZE));
return 0;
}

Can you please suggest a way to accomplish this.
