CAUSE

RESOLUTION
Perform the following troubleshooting steps to resolve this problem:

 If the .CDX file is corrupted, do the following; otherwise, go to step 2.

  At the MS-DOS prompt, type the following command:  rename .cdx .cbk   In the Command window, type the following command:  USE .dbf  Re-create the .CDX file.  If the .DBF file is corrupted, do the following; otherwise, go to step 3.

 Restore the backup .DBF file if you have one. If you have no backup file, go to step b.</li>  In the FoxPro Command window, type the following commands:  <pre class="CODESAMP">        USE .dbf COPY STRUCTURE TO test.dbf WITH CDX USE SELECT USE test.dbf SELECT test.dbf APPEND FROM .dbf </li></ol> </li> If the FOXUSER.DBF file is corrupted, do the following; otherwise, go to step 4.

  At the MS-DOS prompt, type the following command:  <pre class="CODESAMP">        RENAME foxuser.dbf foxuser.dbk </li> Restart FoxPro. A new FOXUSER.DBF file is automatically created.</li></ol> </li> If the problem is occurring with a distributed application, make sure the .ESO or .ESL files aren't corrupted. If they are, replace the support libraries. If the problem doesn't involve a distributed application, go to step 5.</li>  To determine if there is a memory conflict, perform a clean boot of your computer. For more information on this topic, query on the following words in the Microsoft Knowledge Base: "clean and boot and unnecessary"</li> Disable any video or system ROM shadowing.</li>  To make sure there aren't any hard disk errors, type the following command at the MS-DOS prompt:  <pre class="CODESAMP">     chkdsk /f </li> If steps 1-7 don't resolve the problem, reinstall FoxPro.</li></ol>

MORE INFORMATION
The error may have been caused by a corrupt file, and FoxPro, after trapping for this error message, tries to close all open files in an attempt to prevent further file corruption.

Another possibility is that there is an invalid SET TEMP in the AUTOEXEC.BAT or CONFIG.FPW files.
