Is there a way to get the screen resolution in C++?
I have searched MSDN but with no luck. The closest thing I found was ChangeDisplaySettingsEx()but that doesn't seem to have a way to just return the res without changing it.
有没有办法在 C++ 中获得屏幕分辨率？
我已经搜索了 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;
}

In Embarcadero C++ builder you can get it like this
在 Embarcadero C++ builder 中，你可以像这样得到它
