KeyUp in MsgBox

[Amaro Cantador]

Hi,

I need help in the following:

I have a base class, called frmBase, in wich I have a routine that gives to
all form objects a handle to track the KeyUp Event of all inherited class
object, to centralize them.

When in the derivated class, called frmXPTO, the users press the Enter key
ou Esc Key this routine will be called (so far so good) catches wich key was
pressed and, if it was the Enter key it will validate each textbox text (as
it must be).

If the text of a textbox doesn't fill the needs it wil show a MsgBox
indicating what's wrong (that's good).

What's wrong is that in the MsgBox if the user presses the Enter key to
close it, it will fire up the KeyUp handler routine, doing all again, i.e.,
frmXPTO is derivated from frmBase, catches up the Enter key firing up the
KeyUp handler routine.

All this is in Windows Forms Application.

Thanks,

Amaro
