    I thought there was a discussion about detecting it.

    Can someone give me a link?

    This happens only with MouseMove and MouseUp on the desktop.
    If you want to avoid getting values from outsides you must check if x and y are insides the form limits.
    Code:
    If x >=0 and x<= Form.Width and y>= 0 and y<=Form.Height Then
    Be aware that there is also a difference in the behaviour of the MouseMove event between the desktop and the device. On the desktop the MousMove event is fired even without a MouseDown event, on the device the MouseMove event is only fired after a MouseDown event (the contact of the stylus is needed). To avoid this you should add a flag in the MousDown event, test it in the MouseMove event and set it back in the MousUp event:
    Code:
    Sub Form_MouseDown(x,y)
      FlagMouse = 
    1
    End Sub
     
    Sub Form_MouseMove(x,y)
      
    If FlagMouse = 1 Then
      
    End If
    End Sub
     
    Sub Form_MouseUp(x,y)
      FlagMouse = 
    0
    End Sub
    Best regards.

    Thanks for the response.

    I was actually hoping it was possible on the device.

    I was having issues with a PInvoke to GetIdleTime / GetTickTime.
    It wasn't working the way I hoped.
    And thought if I could detect when there were no clicks outside a form, it would achieve the same.

    I have since worked out the correct calculation and works great.

    Thanks Anyway

    I'm still tring to get this to work on the desktop, but i can only get the mousemove to trigger when it is on the form...
    :-/

    probably because i'm using sub form1_mousemove(x,y)..

    Thanks Byak@,

    Any chance you also know how to get the pixel color
    at a specific position, also outside of the form?

    I've been fiddling with the door lib... but it is not my day

    emm...i'm not find it in msdn =(
    but you can get screenshot with dzHW.dll and get mouse position.and now you can get pixel color.but this method not fast.

    In case anyone is wondering, the above worked,
    e.g. I'm taking a screenshot of 1x1 pixel and checking the RGB color
    with Agraham's ImageEX lib...
    Put this sub on a timer and presto... a color picker :)
