How to Remap FoxPro 2.x Connectivity Kit Functions to 3.0

ID: Q129754

3.00 WINDOWS

The information in this article applies to:

• Microsoft Visual FoxPro for Windows, version 3.0

SUMMARY

Visual FoxPro provides the same ability to use SQL Passthrough commands that earlier versions of FoxPro provided. However, the names of the functions have changed somewhat in Visual FoxPro version 3.0, so FoxPro version 2.x code that uses these functions will no longer work as expected in Visual FoxPro. This article provides code that re-maps the old function names to the new function names.

MORE INFORMATION

If you have a main program file or a procedure file, add this code to it and call the functions as you normally would. If you do not, you may want to make a procedure file and use the SET PROCEDURE command to reference these functions at run time.
