[ENHANCED] VFP 9.0 FIX - OPEN INDEX FILES WITH THE TABLE AUTOMATICALLY
January 2024
--------------------------------------------------------------------------------
CCB
1. BUG:
In vfp9 (and vfp6, vfp7, vfp8), it will open structural compound index files (tablefilename+".cdx") with the table automatically.
In VFP Advanced, it will open structural compound index files (tablefilename+".cdx") with the table automatically.
In VFP Advanced, if we enable opening nonstructural compound index files with the table automatically,
it will open nonstructural compound index files (tablefilename+"_index*.cdx") with the table automatically.
In VFP Advanced, if we enable opening standalone index files with the table automatically,
it will open standalone index files (tablefilename+"_index*.idx") with the table automatically.
2. CAUSE:
There are some BUGs in the following code.
3. RESOLUTION:
We can write some code to fix the BUG.

VFP 9.0.0.6602 (SP2)
VFP 9.0.0.7423 (SP2)
The bug has been fixed in VFP Advanced.
IMPORTANT NOTE:
The following commands will open index files with the table automatically:
ALTER - SQL command
DELETE - SQL command
DO FORM command - DataEnvironment object
INSERT - SQL command
LABEL FORM command - DataEnvironment object
REPORT FORM command - DataEnvironment object
SELECT - SQL command
UPDATE - SQL command
USE command
The following commands will not open index files with the (destination) table automatically:
ADD CLASS command
BUILD command
COPY command
CREATE command
IMPORT command
JOIN command
MODIFY command
OPEN DATABASE command
PACK command
SELECT ... INTO CURSOR NOFILTER - SQL command
SELECT ... INTO TABLE - SQL command
SET CLASSLIB command
SET RESOURCE command
SORT command
TOTAL command
The following functions will not open index files with the table (cursor) automatically:
SQLCOLUMNS() function
SQLEXEC() function
SQLMORERESULTS() function
SQLPREPARE() function
SQLTABLES() function
XMLTOCURSOR() function
When VFP Advanced opening the following table files, it will not open index files automatically:
Database table files (.dbc, .dct, .dcx)
Form table files (.scx, .sct)
Label table files (.lbx, .lbt)
Menu table files (.mnx, .mnt)
Project table files (.pjx, .pjt)
Report table files (.frx, .frt)
Table files without a file extension
Temporary table (cursor) files (.tmp)
Visual class library table files (.vcx, .vct)
For the COPY ... WITH CDX command, it will copy structural compound index files (tablefilename+".cdx").
If we enable opening nonstructural compound index files with the table automatically in Visual FoxPro Advanced,
it will also copy nonstructural structural compound index files (tablefilename+"_index*.cdx").
If we enable opening standalone index files with the table automatically in Visual FoxPro Advanced,
it will also copy standalone index files (tablefilename+"_index*.idx").
