可能重复:
如何从 hWnd 获取显示器屏幕分辨率?
有没有办法在C++中获取屏幕分辨率?
我搜索过 MSDN 但没有运气。我发现的最接近的是
ChangeDisplaySettingsEx
() 但这似乎没有办法只返回 res 而不更改它。
#include "wtypes.h"
#include <iostream>
using namespace std;
// Get the horizontal and vertical screen sizes in pixel
void GetDesktopResolution(int& horizontal, int& vertical)
{
RECT desktop;
// Get a handle to the desktop window
const HWND hDesktop = GetDesktopWindow();
// Get the size of screen to the variable desktop
GetWindowRect(hDesktop, &desktop);
// The top left corner will have coordinates (0,0)
// and the bottom right corner will have coordinates
// (horizontal, vertical)
horizontal = desktop.right;
vertical = desktop.bottom;
}
int main()
{
int horizontal = 0;
int vertical = 0;
GetDesktopResolution(horizontal, vertical);
cout << horizontal << '\n' << vertical << '\n';
return 0;
}

在 Embarcadero C++ builder 中你可以这样得到它
Screen->Height;
Screen->Width;
这是特定于 Embarcadero 产品提供的 VCL 框架:C++ Builder、Delphi。
