I have no problem with that, its the fact that i create it at RUNTIME... i dont place it on my form at design time, so when i try make an event for a text box that has not been created yet i cant! know what i mean? thanx again!:confused:
ok What code u r writing?

ok What code u r writing?
i create a rtf box in many places and set it as a child control of a tab control... but i call it up like this when i want to change its values...
Dim rtf As New RichTextBox() rtf = TABS.TabPages(TABS.SelectedIndex).Controls.Item(0)and so you see... since its created at runtime... how do i call its events? thanx, dax :) -

Doesn't this create a control, then discard it for one that's already within the tab page ? Either way, you can attach events to a control in code, at least you can in C#.

If you create a control at runtime, you have to wire up the events yourself at runtime, just like the designer generated code does when you drop a control on the form. Lookup AddHandler and RemoveHandler on MSDN and it'll show you how to do this...
