如何从 hWnd 获取显示器屏幕分辨率?

How to get the monitor screen resolution from a hWnd?

我使用的是 hWnd，因为窗口可以位于多个显示器中的任何一个.

I am using a hWnd because the window could be located on any one of multiple monitors.

即hWnd 上/左坐标位于屏幕分辨率为 800 x 600 的显示器上.

i.e. the hWnd top/left coordinate is on a Monitor that has a Screen Resolution of 800 x 600.

我用一种叫做 PL/B 的语言编程，它允许调用 Windows API.

I program in a language called PL/B and it allows calling Windows API.

推荐答案

user32 函数 MonitorFromWindow 允许您传入一个 hwnd，并返回它所在的监视器的句柄(或默认值 - 有关详细信息，请参阅链接的 MSDN 文章).有了它，您可以调用 GetMonitorInfo 来检索MONITORINFO 结构，其中包含 RECT 详细信息其分辨率.

The user32 function MonitorFromWindow allows you to pass in an hwnd, and returns a handle to the monitor it's on (or a default - see the linked MSDN article for details). With that you can call GetMonitorInfo to retrieve a MONITORINFO struct which contains a RECT detailing its resolution.

请参阅多屏幕参考有关详细信息，请参阅 MSDN 部分.

See the Multiple Screens Reference section of MSDN for more details.

我会添加示例代码，但我不知道您引用的语言，也不知道 C# 示例代码对您有多大用处.如果您认为它会有所帮助，请告诉我，我会很快编写一些代码.

I'd add example code but I don't know the language you referenced, and I don't know how useful C# example code would be to you. If you think it'll help, let me know and I'll code up something real quick.
