Child windows and different threads

[De Nardis Andrea]

Hi folks, I have the following problem. Window B must be child w/ respect to Window A. Window A and Window B are on different threads (by the way, A is running on the main process thread). Is it possible to make window B be child of window A in such a sitiuation? if not, how to simulate the correct behaviour, for example being notified of the messages window A receive, and so behave accordingly? Thanx a lot. You always brighten me :-) Andrea
