I thought you were a newbee lol,,,,then i looked at your stats,,,, am i under thinking your solution

As an example suppose I am deriving a form from a base form.  The base form has a button on it.
How can I determine from the base form if the button's click event is being handled on the derived form?

I suppose I'm looking for a function that would do the following:

For Each handler in assignedHandlers(button.click)

 

by: 5thcavPosted on 2006-01-15 at 16:40:07ID: 15707314

in your base form
Public Event Button1Active(ByVal sender As Object, ByVal e As EventArgs)
Public Event Button2Active(ByVal sender As Object, ByVal e As EventArgs)
Public Event Button3Active(ByVal sender As Object, ByVal e As EventArgs)      

in your buttons on the base form
RaiseEvent Button1Active(Me, EventArgs.Empty)

in your derived form

Private Sub Button_ButtonActive(ByVal sender As Object, ByVal e As EventArgs) Handles base.Button1Active, Base.Button2Active, Base.Button3Active
        ' some actions are only enabled when certain panes are selected
 End Sub

something like this?
