HOWTO: How to Allow OS/2 Programs to Run Across Logons (137861)

SUMMARY

When you launch an OS/2 application from a service in Windows NT, the OS/2 application terminates when the current user logs off. If you want the application to continue running after the user logs off, you can:

Run the OS/2 application from the Windows NT Resource Kit utility called SRVANY.

-or-

Launch Os2.exe directly from the service, and pass the /S switch. The syntax of the call would be:

   CreateProcess (
      NULL,
      "OS2.EXE /S /P <full path to exe> /C <command line>",
      . . .
      );

The <command line> includes the name of the executable. For example:

      CreateProcess (
         NULL,
         "OS2.EXE /S /P C:\\OS2BINS\\LS.EXE /C LS *.c",
         . . .
         );

In either case, you must make sure that the first OS/2 application started after booting your system is the one you want to run as a service.

MORE INFORMATION

The OS/2 Subsystem automatically shuts down when a user logs off. Using the /S switch on the Os2.exe command line tells the OS/2 Subsystem that it is running in the context of a service. The Subsystem then continues to run across logons.

The reason the application must be the first OS/2 executable launched is that if an OS/2 Subsystem server is present, it will be used rather than starting a new one to run as a service.

Any OS/2 applications launched by the interactive user will still be terminated upon logoff.
