FIX: Adding Description to Table's Index in DBC Corrupts Table (141354)

MORE INFORMATION

Steps to Reproduce Problem

1. In the Command window, type the following commands:

      SET EXCLUSIVE ON
      CREATE DATABASE mydata
      MODIFY DATABASE mydata

2. Add a new table, and add the first and last name fields to the table. Name the table Mytable.
3. Create a regular index on the last name field. You do not need to add any data to the table.
4. Close the Database Designer.
5. In the Command window, type:

      CREATE PROJECT myproj

6. Add Mydata to the project.
7. Expand the data section to expose the fields and index for the table you created. With the index expression selected in the project, right-click and select Edit description. Enter any description.
8. Close the project, and in the Command window type:

       CLOSE ALL
       CLEAR ALL

9. Re-open the project and try to edit the database. Visual FoxPro will return the error message:
   FILE C:\VFP\mydata.dbc is an invalid database.

Example Resolution

The following steps should resolve this problem. Note that thes steps have been performed under Windows NT only; they have not been tested on other platforms.

1. Close the project, and ensure that Mydata is open.
2. In the Command window, type:

      VALIDATE DATABASE RECOVER

3. Visual FoxPro will return the following information:

      Validate Database MYDATA:
      Rebuilding structural index.... Index rebuilt
      Object #8 (Index 'lastname'): Bad property types or lengths: 1. (Fixed)

Your description will be removed from the index and you can now make additional modifications to the table.
