Ok, all you Microsoft people out there, here's a fun one.... How can I find the Window ID of a Child process? I can (obviously) get the PID from my DosExecPgm call, but how can I then get a handle on the new process's window? I KNOW there must be a call for this, but I can't find it in the INDEX... :-# I know I could enumerate all the top level windows and try to find the one I'm looking for, but that seems a little barbaric. Another, related question: When you ExecPgm a new process ASYC, does it continue to run after the parent dies? (please say yes.) Thanks in advance for your help! hdan@sleepy.cc.utexas.edu (Really Dan Higdon)

In the parent and child do: hAtomTbl = WinQuerySystemAtomTable(); WM_Your_atom = WinAddAtom(hAtomTbl,"SOMENAMEYOUCHOOSE"); Have the child when able do a broadcast message that only the parent would know. WinBroadcastMsg(hWnd,WM_Your_atom,MPFROMHWND(hWndChildFrame),0L,BMSG_POSTQUEUE); And in the parent be ready to recieve the message, in this example mp1 would contain the window handle. Once you have this a more private comunication can take place. -- Jack Computer Support Corportion Dallas,Texas Hudler UUCP: {texsun,texbell,attctc}!csccat!jack
