Mouse OutSide A Form

[eww245]

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.

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:

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)..

eww245 see this post http://www.basic4ppc.com/forum/questions-help-needed/3711-prevent-screen-saver.html#post24541
you can get mouse position with it.

[Mr_Gee]

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

[Byak@]

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.

[Mr_Gee]

that was my next option... hopefully someone else reads this..
or i might make a new post

:-)

[Mr_Gee]

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 :-)

Thank you. It's a good and interesting solution.
