Configuring Win16 Applications to Run in Separate Memory Spaces

---

There are a few ways to run Win16 applications in separate memory spaces. These include the following:

• Any time you start a Win16 application from the Start menu using the Run option, you can select the Run in Separate Memory Space option (see Figure 5.18).

The Run in Separate Memory Space option is available only when you type in the path to a Win16 application. This is not available for any other types of applications because by default they run in their own memory space. Only Win16 applications will share the same memory space by default.

• At a Command prompt, you can start a Win16 application by typing start /separate application.
• Any shortcuts that point to Win16 applications can be configured on the Shortcut tab of the Spinner Properties dialog box to always run in a separate memory space (see Figure 5.19).
• The final way to configure a Win16 application to run in a separate memory space enables you to configure any file with the same extension to always run in a separate memory space when the data document is double-clicked on in the Windows NT Explorer. Editing the File Types tab of the View, Options properties, does this. To configure this type of process, follow these steps:

1.	Start the Windows NT Explorer.
2.	From the View menu, choose Options.
3.	Click on the File Types tab.
4.	If your default application to display bitmap images was a 16-bit Windows application, you can change its properties for execution, by first selecting Bitmap Image from the Registered File Types list and then clicking on the Edit button.
5.	From the list of possible actions, select Open and click on the Edit button to modify the Open action.
6.	Figure 5.20 shows how the Application Used to Perform Action option was changed to run the executable Imgmgr.exe in a separate memory space. The executable was set to be cmd /c start /separate c:\cw\imgmgr.exe %1.
