So why in the world you cant start with the regular:

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click

'Code here

End Sub

and replace 'Code here with something to detect if it was a right click?  Further why can you do something exactly like above but replace "Handels Button1.Click" with something like "Handels Button1.RightClick"?

I did figure out that I needed to add my own event handler:

AddHandler Button1.MouseDown, AddressOf myEvents.myMouseDown1

Then added a Class:

Public Class myMouseEventClass
     Public Sub myMouseDown1(ByVal sender As Object, ByVal ex As MouseEventArgs)
        If ex.Button = MouseButtons.Right Then
          'Code here
        End If
    End Sub
End Class

Works fine but here is my problem, from within this class I cant touch any variables unless they are globally declared as Shared. Further I can call any other subroutines unless they are shared as well.

My main problem is that I would like to update part of the main form of my program, namely a Label1.Text with something from within the 'Code here section in the event handler.  I also need to peform another button click from within the clase as well, namely Button2.PeformClick() but the same problem.

Trying to do either gives me:

Reference to a non-shared member requires an object reference

from the IDE and a subsequent:

Cannot refer to an instance member of a class from within a shared method or shared member initializer without an explicit instance of the class.

From the Build Errors.

How can I get aroud this and do one simple thing, update a text box when I right click on a button.

Thanks for any insight anyone has.

I got the answer... create an event handler for MouseDown, not Click.

--- Code Start ---

   Private Sub Button1_MouseDown(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles Button1.MouseDown
      If e.Button = MouseButtons.Right Then
         lblOutput.Text = "Right button was clicked."
      End If

      If e.Button = MouseButtons.Left Then
         lblOutput.Text = "Left button was clicked."
      End If
   End Sub

--- Code End ---

Tested and it works.
