assign single event handler code to events of multiple control fields
Posted on 2011-03-15
I have multiple e.g. Text field controls on a Windows form (VB6).
Instead of coding always the same routine for e.g. TextChanged events of each of the fileds I like to assign those events to the same coding instance.
The "sender" System.Object parameter should allow me to handle any differences in the singlke code insatnces related to the various Text control elements.
I assume that such an approach should also be able to handle the different "e" System.EventArgs in a single coding instance.
My problem is that I don't know how to specify the individual event handlers for each of the control fielsd with assignment to the single coding instance.
I assume that this is a stupid questing of a novice to Studio 2010 / VB6 programming.

In VB.NET, you have 3 options:
You can assign the handler through the properties window by multi-selecting the controls you want to set the handler for, and then clicking the lightning bolt in the Properties pane; then it's a matter of simply selecting the appropriate event and its respective handler.
You can use a "Handles" clause on your event handler and list each control.event you want that handler to handle
You can use the AddHandler() function to assign a handler to an event
