Can't understand, if there is way to make dialog form act like ordinal dialog form by calling uCreateDialog? I mean tab-movements, WM_CANCEL message and so on, because I just do not receive them if I create dialog by that call. On the other hand, I have nice form by calling uDialogBox(), but it is modal, that's seems to be inadmissible... what I am doing wrong?

You need to call modeless_dialog_manager::add() in your WM_INITDIALOG and modeless_dialog_manager::remove() in your WM_DESTROY handler to enable dialog message processing for a modeless dialog in the main event loop.

Thanks a lot.
