Hello,
I have again problem with native windows.

What i want to do is to open FIRST native window and then from that window open SECOND window. In that Second window i have function which should change text in FIRST windows text area but I always get error when i try that.

So my question is:  How to access controls in one nativ window from another window

P.S.
I know how to access controls and objects in main window::
Application.application.my_Control.text = "test".

MAIN WINDOW -----opens-----> Window 1 ------opens -----> Window2

Then

Window2 ----sends value of text box ----> Window 1
