wait until a program open Topic is solved

[zortanmax]

Hi everyone
I want to write some code to wait for opening a program or window and then run the next part of the code, but I do not know which code to use.
I used WinWait or WinWaitActive, but before these commands should be running a program or window.
I need your help
