Hi guys! :)
  
 Im using Microsoft Multipoint SDK to do this, and I have come so far now but I cant figure this out.
 I have 2 mice connected, if left button on one of the mice is pressed, then button5 is clicked.
 I have tried something like this:
  
     Private Sub Button1_MouseDown(ByVal sender As System.Object,  ByVal e As System.Windows.Forms.MouseEventArgs) Handles  Button1.MouseDown
         If e.Button = MouseButtonState.Pressed Then
 ....
         End If
  
 ( and getting an error with mousedown at the handles like this:  Method 'Private Sub Button1_MouseDown(sender As Object, e As  System.Windows.Forms.MouseEventArgs)' cannot handle event 'Public Event  MouseDown(sender As Object, e As  System.Windows.Input.MouseButtonEventArgs)'  because they do not have a compatible signature. )
 Im not sure if the code above is the right to use..
  
 But that code only assign button for one mouse I think. Im going to use two mice here, and want to assign "job" for each mouse.
  Short story: connect 2 mice in the computer and when left button on  for example mouse 1 is pressed when a button is clicked. So instead of  moving the cursor to each button and press it, I want the cursor to be  anywhere on the wpf screen and be able  to press buttons connected the mouse clicks.
  
 I hope you guys understand what I mean.
 
 Thank you so much for all help!
