Hi. I am writing a program that I would like to be able to program it to pop up a window in a screen that does not belong to the program. How would I during the initialization of my program, go about finding an address to the appropriate screen structure. I was thinking of having the program delay three secs for the user to switch screens and then use the one that is then active. Or, if that is not possible, have the user enter as an argument, the name of the screen to use. Please respond to MCARTSHA@UREGINA1. Thank you VERY much for your help. If you are also interested in any responses I get to this question, mail me and I will forward the answers. Shan

I was thinking of having /* ints are long */ . . . struct NewWindow new; struct IntuitionBase *IntuitionBase; struct Screen *ascr; struct Window *wdw; . . . main() { . . . ULONG ilock = 0L; IntuitionBase = (struct IntuitionBase *)OpenLibrary("intuition.library",0); if(IntuitionBase==NULL) getout(20); /* Close anything already opened */ ilock = LockIBase((ULONG)0L); /* Don't dally with intuitionbase locked */ ascr = IntuitionBase->ActiveScreen; if(ascr==NULL) { UnlockIBase(ilock); getout(25); } /* Presumably you want to read screen characteristics before setting */ /* the parameters in your new window */ /* Otherwise, it's better to set the new window stuff before locking */ /* intuitionbase. */ new.LeftEdge = . . . new.TopEdge = . . . . . . new.Screen = ascr; . . . new.Type = CUSTOMSCREEN; wdw = (struct Window *)OpenWindow(&new); UnlockIBase(ilock); if(wdw==NULL) getout(22); rp = wdw->RPort; /* Now we're open for business */ . . . getout(0); } Good luck. -- Bill ---------------------------------------------------------------------- William F.
