二.LOWORD && HIWORD

w=0x0101
w1=0x0202

DWORD dwT = 0x01010202;
WORD w=HIWORD(dwT);
WORD w1=LOWORD(dwT)

三.GotoDlgCtrl

Moves the focus to the specified control in the dialog box.

四,SetCapture,ReleaseCapture

当MouseDown的时候,鼠标离开窗体区域然后放开的话，鼠标将无法捕获到MouseUp事件。
如果需要在非窗体区域鼠标放开后捕捉到MouseUp事件的话,则可以在MouseDown事件中调用SetCapture方法,MouseUp的时候调用ReleaseCapture
c#代码示例

protected override void OnMouseDown(MouseButtonEventArgs e)
{
    CaptureMouse();
    base.OnMouseDown(e);
}

protected override void OnMouseLeftButtonUp(MouseButtonEventArgs e)
{
   
    ReleaseMouseCapture();
    base.OnMouseLeftButtonUp(e);
}
