呵呵，够多吧，不用记，要用的时候查下MSDN就好了。由MSDN可以知道传入SM_CXSCREEN和SM_CYSCREEN就得到屏幕的宽和高。详见代码：
[cpp]
// 获取屏幕大小 像素大小
// By MoreWindows( http://blog.csdn.net/MoreWindows )
#include
#include
int main()
{
printf(" 获取屏幕大小 像素大小\n");
printf(" -- By MoreWindows( http://blog.csdn.net/MoreWindows ) --\n\n");
int nScreenWidth, nScreenHeight;
nScreenWidth = GetSystemMetrics(SM_CXSCREEN);
nScreenHeight = GetSystemMetrics(SM_CYSCREEN);
printf("屏幕大小（像素） 宽：%d 高：%d\n", nScreenWidth, nScreenHeight);
return 0;
}
// 获取屏幕大小 像素大小
// By MoreWindows( http://blog.csdn.net/MoreWindows )
#include
#include
int main()
{
printf(" 获取屏幕大小 像素大小\n");
printf(" -- By MoreWindows( http://blog.csdn.net/MoreWindows ) --\n\n");
int nScreenWidth, nScreenHeight;
nScreenWidth = GetSystemMetrics(SM_CXSCREEN);
nScreenHeight = GetSystemMetrics(SM_CYSCREEN);
printf("屏幕大小（像素） 宽：%d 高：%d\n", nScreenWidth, nScreenHeight);
return 0;
}运行结果如下：
