Running FoxPro Applications with DESQview

• Microsoft FoxPro for MS-DOS, versions 2.0, 2.5 and 2.5a

SUMMARY

The text below details how to configure Microsoft FoxPro applications under DESQview, including DESQview program information file (PIF) settings.

MORE INFORMATION

Each FoxPro application that runs under DESQview must have a CONFIG.FP configuration file that specifies a unique location for its resource and temporary files. Using the same FOXUSER.DBF file for multiple applications causes difficulties such as "cannot update file" errors. Sharing the same .OVL file causes problems when FoxPro exits.

To avoid these and other problems, use the following PIF settings:

1. Use the -C option in the PIF Parameters line to specify which CONFIG.FP file is used by each application.

2. Adjust the PIF settings for the amount of memory each FoxPro application uses. The standard PIF settings are as follows:

         Memory Size: 500
         Maximum Program Memory Size: 640
         Maximum Expanded Memory Size: 2048
   

3. The Run In Background and Share CPU When Foreground options can be used to run more than one FoxPro application simultaneously. However, the currently selected window may operate slowly in this environment.

4. Specify NO for the Allow Close Window Command setting. This prevents the user from abnormally terminating a FoxPro application from the DESQview menu.

Notes on Using DESQview

• To activate an application without using the DESQview menu, redefine the DESQview key to another key combination, for example, SHIFT+CTRL. For more information on redefining this key, refer to the DESQview manual or contact Quarterdeck Technical Support at (213) 392-9701.
• If the mouse leaves a trail on the screen, activate the Setup DESQview window and select the proper mouse type from the listed options.
• Do not run disk-organization utilities, such as CHKDSK /F and VOPT, from Big Dos while a FoxPro application is running.
