Could you post for lazy people at least a few lines of that cry?
Edit: and/or post small testing apps...

... sorry, here it is the compiler message and editmask.lay (the cpp file is attached. In it look for the line with
App.UpdateInfo(" from tab1!"); )

It seems the compiler do not see some declaration. I've tried to exchange the relative position of the class but with no positive result.
