How can I call the console program? 1. Hide the console window; 2. Obtain the exit status of the console program.

Shadowwind (Lily has died) 17:22:25 on VC/MFC/ Basic ClassHow to call the console program: 1. Hide the console window; 2. Get the exit status of the console Program

I use system and _ spawnlp. The returned value is exit code, but the window cannot be hidden.
Windows can be hidden with winexec (command, sw_hide), but no exit code is available.

On the 4th floor, keiy () replied to the error: 19:04:11 score 0. I tried it. I have a problem.
CreateProcess if startf_useshowwindow + sw_hide is used
Waitforsingleobject does not return
Getexitcodeprocess does not return values either.
If you do not need startf_useshowwindow, you can get the exitcode normally.
