Ive been working on this since yesterday and its bugging me. Although the
event is firing, The box does not scroll. Can anyone see what Im doing
wrong. I suspect it is stupidly simple.
TIA
SubClass RichtextBox in order to fire the OnVScroll Event
Public Class MyRichTextBox
Inherits RichTextBox
Public Sub PerformVScroll( )
MyBase.OnVScrol l(EventArgs.Emp ty)
End Sub
End Class
- This button invokes the PerformVScroll -
Private Sub Button2_Click(B yVal sender As System.Object, ByVal e As
System.EventArg s) Handles PerformVscroll. Click
RTB.PerformVScr oll()
End Sub
- THis confirms that the event has been raised -
Private Sub handleScroll(By Val sender As System.Object, ByVal e As
System.EventArg s) Handles RTB.VScroll
Console.WriteLi ne("Handling scroll")
End Sub

You're simply causing all event subscribers to be notified that a scroll
has happened. It's not actually performing the scroll. For that, you
would probably either need to:
1) Send the WM_VSCROLL message to your control.
2) or try the ScrollToCaret() function.

The carret worked ok so thanks for that. I looked for examples on how to
send messages to the control but of yet have not found any. Do you have a
good reference I can look at ?
Many Thanks
