SUMMARY
=======

This article describes how to programmatically remove an existing ODBC
datasource instead of manually removing it through the ODBC Administrator. You
can use the SqlConfigDataSource function in Odbccp32.dll for this purpose.

MORE INFORMATION
================

The following sample code demonstrates how to use this API function to remove a
Visual FoxPro Database datasource. To use this code, you need to create a
datasource called rmtest that points to the data1.dbc in your local hard drive.

     DECLARE Integer SQLConfigDataSource IN odbccp32.dll Integer, ;
        Integer, String, String
     DriverName="Microsoft Visual FoxPro Driver"
     IsRemove =SQLConfigDataSource(1,3,DriverName, "DSN=rmtest" + CHR(0)+;
                 "Description=david test"+CHR(0)+;
                 "SourceDB=C:\TEMP\data1.dbc"+CHR(0)+;
                 "SourceType=DBC")
     IF IsRemove>0
        WAIT WINDOW "Deleted"
     ELSE
        WAIT WINDOW "Delete failed"
     ENDIF

Note that the "Description=david test" portion of the connection string can be
omitted and the datasource will still be removed.
