這個程式碼範例是 DesignerShell.cs 檔案中＜Basic Designer Hosting SDK＞範例的一部分。 如需詳細資訊，請參閱基本Designer裝載。

protected override bool OnMouseHover(MouseEventArgs eventArgs)
{
    //Allow other components to process this event by not returning true.
    mouseDown = false;
    return false;
}

    ' Allow other components to process this event by not returning true.
    mouseDown = False
    Return False
End Function
