How can i detect in the second (child) application that the first (parent) is closed. Re: Parent process Neville Franks23-Sep-04 23:26 Neville Franks 23-Sep-04 23:26  I don't understand. You've said the parent closes after the child closes, which means the parent is always running as far as the child is concerned.

But the child must to know when exactly the parent is closed. This is need because i must to change the .exe file. So i thought that i can try to open the .exe file and if this fails it is still running. But this is very unsecure. So i want either to check if the parent process is running or check somehow is the parent's hInstance valid.

If it knew the process identifier, it could call OpenProcess(). "When I was born I was so surprised that I didn't talk for a year and a half." - Gracie Allen Re: Parent process Neville Franks24-Sep-04 12:08 Neville Franks 24-Sep-04 12:08  I can think of several ways. One way would be to use a named Mutex in the child which the parent can signal when it closes. Another would be to use a Memory Mapped File that the parent could write something to when it closed. There may also be someway for the child to find out or be passed the process handle for its parent and it could check on that.

Child can open mutex and wait for mutex abandonment (WAIT_ABANDONED) and know that parent is gone. A mutex will be released with WAIT_ABANDONED if the process owning it is terminated or exits.

Thats not easy to describe in one sentence. I don't know about your skills in VC, but this example from P.J.

B.R.K@3000 Getting Windows Layout Data Tristan Rhodes23-Sep-04 20:04 Tristan Rhodes 23-Sep-04 20:04  I'm not sure whether this is a COM or simply a C++ library query. Basicaly, i've got a program that needs to read the current appearance data of windows. But i can't find where to find the information from ANYWHERE. I need the following values: (For NT) * Title Bar Size * Title Bar Colour * Title Bar Text Size * Title Bar Text Colour * Window Border Size * Window Border Colour For both Active and Inactive windows. I don't really need details on how to do both, just what to do to get them for NT. (For XP) * The shape of windows, i.e. whether windows have the rounded corner, and if so, how I can get the graphics map for them. I can set this manualy, but it isn't dynamicaly changing depending on user settings. * Besides that, I really need similar information as above, Text Size, Text Colour and Title Bar Size. XP doesn't seem to have resizable windows borders, so I don't think I need that. Any pointers into what DLL + Method I should be using would be a great help, as I've trawled through MSDN looking for windows appearance and display API libraries and found squat. Cheers Cata [Edit: I think I found what I'm looking for in GetSystemMetrics + GetSystemColor. If anyone can tell me if this works for both NT and XP, it would be really helpful. I still haven't solved the graphics path for cropped window shapes, so if anyone know what to do about that, I would be greatful.]
