You have to run the VALIDATE DATABASE command on the database container to repair it. STATUS ====== Microsoft has confirmed this to be a problem in the Microsoft products listed at the beginning of this article. This problem has been fixed in Visual FoxPro 5.0 for Windows. 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" (without the quotation marks). 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.
