There is function:
"This method is called by the V runtime system after a dialog has actually
been displayed on the screen. This method is especially useful to override
to set values of dialog controls with SetValue and SetString.
It is important to understand that the dialog does not get displayed until
ShowDialog or ShowModalDialog has been called. There is a very important
practical limitation implied by this, especially for modal dialogs. The
values of controls cannot be changed until the dialog has been displayed,
even though the vDialog object may exist. Thus, you can't call SetValue or
SetString until after you call ShowDialog for modeless dialogs, or
ShowModalDialog for modal dialogs."
