EnumDisplayMonitors样例

以下是一个使用EnumDisplayMonitors函数的样例，它可以列出所有可用的显示器并输出它们的设备名称和分辨率：

#include <Windows.h>
#include <iostream>

BOOL CALLBACK MonitorEnumProc(HMONITOR hMonitor, HDC hdcMonitor, LPRECT lprcMonitor, LPARAM dwData)
{
    MONITORINFOEX monitorInfo;
    monitorInfo.cbSize = sizeof(monitorInfo);
    if (GetMonitorInfo(hMonitor, &monitorInfo))
    {
        std::cout << "Device name: " << monitorInfo.szDevice << std::endl;
        std::cout << "Resolution: " << monitorInfo.rcMonitor.right - monitorInfo.rcMonitor.left << "x" << monitorInfo.rcMonitor.bottom - monitorInfo.rcMonitor.top << std::endl;
    }
    return TRUE;
}

int main()
{
    EnumDisplayMonitors(NULL, NULL, MonitorEnumProc, NULL);
    return 0;
}

输出：

Device name: \\.\DISPLAY1
Resolution: 1920x1080
Device name: \\.\DISPLAY2
Resolution: 1280x1024
