Hi Sergey,

Thank you for taking your time. This is a child Window that includes a ListBox. I activated it:

ACTIVATE WINDOW (MyVCX1) IN WINDOW ('Form1')

Form1 is located inside formset1.

I think, if I know how to access a parent window inside a child window, my problem will get solved.

I really appriciated,
Ali
