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

• Microsoft Win32 Application Programming Interface (API), used with:
  • Microsoft Windows NT versions 3.51, 4.0
  • Microsoft Windows 2000

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",
           . . .
           ); 

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.
