To have a better UI, programmers usually use a borderless form. But there's no caption bar and the form cannot be move. This code help you to move a form by clicking anything that support mousemove, mouseup, mousedown events. See it , it's cool!

Private Declare Function SetCursorPos Lib "user32" (ByVal x As Long, ByVal y As Long) As Long

If Me.Left > (Screen.Width - (Me.Width / 10)) Then Me.Left = Screen.Width * 9 / 10
