Defining a "Seamless" WIN-OS/2 VDM

In order to obtain the highest integration of the Windows V3.0 and Windows V2.x application into the OS/2 V2.0 Workplace Shell, the following definitions must be provided in order to have the application execute in seamless mode:

Select the Program page of the program object's Settings notebook.

Enter the Windows application name in the Path and Filename field. A fully qualified path and filename is necessary.

Select the Session page of the program reference object's Settings notebook.

Click on the WIN-OS/2 window radio button.

All DOS settings are selectable for Windows applications via the Windows Settings page dialog; Windows settings are included in the same list.

The "WIN-OS/2 Window" radio button indicates that the associated Windows application program is to be initiated in a "seamless" Windows VDM. This is a single application VDM. However, the WIN-OS/2 Program Manager may be registered with the Workplace Shell as a "seamless" WIN-OS/2 program object. Once the Program Manager is up and running, the user may launch any other Windows program from it. Of course, this assumes that other Windows programs were installed through the Program Manager, and that they all run in the same WIN-OS/2 session.

A new parameter is added to the SYSTEM.INI file: WOS2VDMApps=!clipwos2,!ddeagent

The WIN-OS/2 Program Manager reads this line for "seamless" WIN-OS/2 VDM, to determine which applications to pre-start.

Since "WIN-OS/2 Window" is the default Windows application setting, all Windows program objects that are created through the Windows Migration utility (for standard mode Windows applications) will default to that setting. If a user chooses to execute a Windows application by double clicking its program file's icon in the Drives folder, rather than its program object icon (if any), then the Workplace Shell will attempt to initiate it in a "seamless" Windows environment.
