Tough Guru test on children

Author	Message
Dan Champag #1 / 5	Tough Guru test on children Ok, here is what I think is a tough one. I have a program that attaches and maps drive letters on Novell. The program then "watches" to see when the program terminates and then kills the network connection. Everything is working fine. However, there are a couple of programs that "span" another program. Here is what happens: Myprogram connects maps a drive Program1 is started Program2 is started from Prog1 Program1 ends Myprogram sees Program1 ended and unattaches network server Program2 is left{filter} with the drive mapping gone QUESTIONS: How can I find out if Program1 starts another program? Is there a way to get a winhandle or something? Would Program2 be concidered a "child" window?

I don't believe Program2 could be considered a child window. A Shelled program (even if it's done with the WinExec API function) is a task independent of the Shelling program. Finding out whether any given program starts another would be very tough indeed, if possible. I don't have any ideas for you there but would be interested in hearing about any that come your way since I do a lot of programming along this line. Perhaps you could scan through the task list using the GetModule... API functions, obtaining the program paths to determine whether there are any additional programs running from a given resource before you disconnect it. This would also cover those situations where you happen to have more than one program running from a given resource without them being otherwise related. Cordially, Bob Moss

We had this problem a kopla years ago; lucky enough, all 3 pgms were made by ourselves, so we were able to tune them. Quote: >Is there a way to get a winhandle or something? You can have a polling loop that looks for Program2's window (FindWindow) if you know its title. A neat place might be the GetModuleUsage(Program1) loop. If you run Program1 asynchronously then I'm afraid you're lost in space/time... Quote: >Would Program2 be concidered a "child" window? Hardly.

Should program1 close program2 when it closes? It so, have program1 shut down program2. If not, have Myprogram monitor program1 and program2. You will have to check to see if either program is running first though. Chris S. Newell Univ. of Missouri-Columbia Dept. of Telecommunications 5 Telecom. Bldg. Columbia, Mo. 65211 (314)882-2762

Have you tried the TaskFirst(), TaskNext() calls in the ToolHelp library? They return a TASKENTRY structure that contains a thing called hTaskParent. You never know but Windows may retain the relationship between parent and child task in there(?) -- Steve Lewis, Smartware Ltd., UK
