Hello,
from my program under Windows (a gui) I call an external program made itself with a gui (but it could be a console application), say childgui.exe by the command:
I observe that the child process is became like a modal dialog and prevent me to use in the meanwhile the parent program. Only when I close childgui.exe the control come back to the main program.
I would like to know if there is a way under Windows to let the child process to operate indipendently of the main exe without to stop it. (for some reason I cannot avoid the use of system() because the child process is a sort of external plugin that I do not know in advance, but perhaps there is a better way to run it).
Thanks,
Luigi

Use Createprocess in combination with GetExitCodeProcess to get the result or use another thread whith the system function.
I prefer using the function Createprocess over the function system.
