在Windows 10中,我们如何确定窗口所属的虚拟桌面？

关于
Windows 10及其新的虚拟桌面功能,有没有办法确定特定窗口属于哪个虚拟桌面？并且,哪个虚拟桌面处于活动状态？

使用截断工具可以看到问题.打开该工具,然后选择一个新建/窗口剪辑.当您移动鼠标时,剪切工具会突出显示没有窗口的区域,但在另一个虚拟桌面上的该位置有一个窗口.

In this picture,the Snipping Tool is highlighting an empty spot.

截图工具不知道特定窗口所在的虚拟桌面.

Here’s the same question on MSDN Forums,unanswered,but with lots of additional detail.

抱歉,我的状态不够高,无法插入图片或包含更多链接.

Windows SDK Support Team Blog通过
IVirtualDesktopManager发布了
C# demo to switch Desktops：

    );

[PreserveSig]
int MoveWindowToDesktop(

    [In]Guid CurrentDesktop
    );
}

[ComImport,Guid("aa509086-5ca9-4c25-8f95-589d3c07b48a")]
public class CVirtualDesktopManager

}
public class VirtualDesktopManager
{
    public VirtualDesktopManager()
    {
        cmanager = new CVirtualDesktopManager();
        manager = (IVirtualDesktopManager)cmanager;
    }
    ~VirtualDesktopManager()
    {
        manager = null;
        cmanager = null;
    }
    private CVirtualDesktopManager cmanager = null;
    private IVirtualDesktopManager manager;

    public bool IsWindowOnCurrentVirtualDesktop(IntPtr TopLevelWindow)
    {
        int result;
        int hr;
        if ((hr = manager.IsWindowOnCurrentVirtualDesktop(TopLevelWindow,out result)) != 0)
        {
            Marshal.ThrowExceptionForHR(hr);
        }
        return result != 0;
    }

    public Guid GetWindowDesktopId(IntPtr TopLevelWindow)
    {
        Guid result;
        int hr;
        if ((hr = manager.GetWindowDesktopId(TopLevelWindow,out result)) != 0)
        {
            Marshal.ThrowExceptionForHR(hr);
        }
        return result;
    }

    public void MoveWindowToDesktop(IntPtr TopLevelWindow,Guid CurrentDesktop)
    {
        int hr;
        if ((hr = manager.MoveWindowToDesktop(TopLevelWindow,CurrentDesktop)) != 0)
        {
            Marshal.ThrowExceptionForHR(hr);
        }
    }
}

调用GetWindowDesktopId以获取桌面GUID.
