Hello
im not win32 programmer and its all new to me.
i like to open process from my parent win32 application ( ok this is i know how to do)
the child process then write to text file and close it self . how can i detect in the parent application that the child application done writing to the text file . and then from the parent app to read the text file . this is all in win32 c++
Thanks
A slight modification of Benoits answer. You can create an event in the parent process and wait for that event with WaitForSingleObject. This event can then be signaled by the child through a call to SetEvent.

It’s important that the child process will inherit all inheritable handles, so CreateProcess has to have the fifth parameter set to true (bInheritHandles).
This way the child process doesn’t have to exit for you to check that the file has been written.
