I have 2 processes, one is A and the other is B.
A will launch B and wait for B. After B finishes, it will generate a string value.
How does A get this string value?
platform is windows.
what I can think about is using registry, or a file. And API GetExitCodeProcess can only get exit code.
Is there any other better way?
thanks a lot.
There are many Windows IPC resources.

You can write the string to stdout and get it with an unnamed pipe:
