Re: Convenient way to parse Enter on a textbox?

[Bruce Steers <bsteers4@xxxxxxxxx>]

TextBox and some other controls have an Activate event fired in a return
press.

Public Sub TextBox1_Activate()

  Button1.value =True

End

To get out of the event handler you could start your button click using a
timer.
