ID: Q162412

The information in this article applies to:

Microsoft FoxPro for Windows, versions 2.5, 2.5a, 2.5b, 2.6, 2.6a

SYMPTOMS

When you are running a program or run-time FoxPro executable, which is repeatedly opening and closing the same FoxPro for Windows database file, the following error messages appear:

Illegal Seek Offset

followed by:

File In Use

This error might only occur when a second workstation (or session of FoxPro for Windows) is running a program that is seeking to read a record in the first FoxPro for Windows database file and then update a second FoxPro for Windows database file.

CAUSE

PCAnywhere versions 7.5 or 8.x by Symantec add the following line to the Windows 95 registry:


   [HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\VxD\SYMEVNT]
   "StaticVxD"="C:\PROGRA~1\SYMANTEC\SYMEVNT.386"
