Undocumented FoxProNFP

Functions

Part I

by Bill Anderson

Here’s the list of undocumented FoxPro/VFP functions posted to the Wiki board. Most of it is from my input, with a smattering from others.

CLEAR SCREEN

I think this command would clear out screen variables (the rare memory variable type “S”, if I remember correctly).

CLOSE PRINTER

This command is supposed to do the same thing as SET PRINTER TO. The latest HackersGuide documents this command...

DISPLAY HISTORY

This command would list all the dBaselll+ interactive commands, one screen at a time. If you used the TO PRINT option, this would go to the printer. The TO FILE option appears to “work” as well in VFP, in the sense that it doesn’t generate an error message.

DISPLAY USERS

This command only returned results when one was using the dBaselll+ LAN Pack, returning a user list one screen at a time.

FILER

This command used to bring up the Filer dialog. Unfortunately, this filer dialog died — the tool didn’t get updated for long file names. There is a FILER.DLL to replace it but I never get around to using it...

The filer dialog used to be quite handy. It was a quick and easy way to search for text strings among a group of programs or screens. That capability is not part of base product any more.

While Filer.DLL doesn’t have quite the functionality of the FP2x

Filer, in the tools\filer subdirectory of VFP MS provides a form

which hooks into the DLL to provide the text search capabilities.

Type DO FORM HOME(1 )+ ‘tools\fller\filer.scx’ to run it. Or you

At LA Fox

Out and About

by Bany R. Lee

June 19, 2000, 7:30 PM. FoxFire Unleashed! Bill Wood,

Program Manager and primary developer of the latest, just- released version of FoxFire! will be here to dazzle and delight.

July 17, 2000, 7:30 PM. Kristyne McDaniel. Kris will be here talking about configurable toolbars.

August 21, 2000, 7:30 PM. John Miller. Conceptual Design To design conceptually means to design without reguard to the platform, language or architecture.

This presentation will focus on the benefits of using conceptual design as a means for adapting to changes in the design of applications. An overview of Conceptual Design and Conceptual Design Methodologies will be presented and the techniques for mapping Conceptual Designs to physical implementations will be explained. A specific Conceptual Design Methodology will be presented that will demonstrate the following:

Derivation of a physical object model and physical data model from a conceptual model

Creation of the SQL queries required to bind the object model to the data model

The use of XML data marshalling and XSL templates to produce a web application to manipulate the data through the object model

While the implementation will largely be in Visual FoxPro, the methodology is technology independent and could be imple (Con’t, page 2)
