Windows – winapi: CreateProcess but hide the process’ window

c++processwinapiwindows

I am using CreateProcess to create a cmd.exe process that is passed a parameter that it executes and quits, this makes command prompt flash up on the screen.

I tried to avoid this by setting STARTUPINFO struct wShowWindow to SW_HIDE but this parameter seems to affect the calling window, not the window for the process that gets executed.

Is there anyway that you can use createprocess to launch a program that is hidden from view?

Also what is the proper winapi standard way to get enviroment variables?

Best Solution

If its just a console app you can also use the CREATE_NO_WINDOW flag as part of the CreateProcess call itself, e.g.

CreateProcess(NULL, lpszCommandLine, NULL, NULL, FALSE, 
              CREATE_NO_WINDOW, NULL, NULL, &si, &pi);

Also, see this page for information about environment variables.
