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.

#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
