window but not dialog

[_pi]

ok, that works when i use it in combination with a listbox selection.
i first use different buttons on pages, like send and ok ...

how can i get the current page number ?
its needed to use sel for page default button action.
on page 1 (i start with page 1) DT_Page(hDlg 2)
on page 2 DT_Ok hDlg

and when using only one default button how to change the label ?
page1 = "Send"
page2 = "OK"

thanks :roll:
