Program Error Invalid Seek Offset
it has been partnered with the "Windows - Delayed Write Failed" I am pretty convinced it is tied to network disconnectivity. The solution for me has been to reboot the machine and restart the background process. CS I am looking for information about the possible causes of this error. We are running a VFP 8.0 application (SP1), with the main program executable and the data residing on a mapped network drive. The server is running MS Small Business Server 2003. The client computers are running Windows XP. After the FoxPro program is running for a while, the Invalid Seek Offset error will pop up. Of course, I cannot trap this error so I do not know what line of code may be triggering the error. I also have the program running on a Windows 2000 machine under the same conditions, but have yet to experience the error on this machine, so I am wondering if it is an XP thing. In addition, there has also been a "Windows - Delayed Write Failed" from the OS on one machine. Do these problems have anything to do with the fact that I am mapping to the executable rather than running a copy of the executable local on each client pc? Part of the cause seems to be somewhat frequent disconnects from the network, which we are addressing, but is there a way to make the FoxPro app react to these problems in a "nicer" way? And, what is generally thought to be the cause of the Error 1103? Thanks for the help. We've seen this happen mostly with marginal or intermittent network connectivity. Don't have a good way to troubleshoot it beyond maybe checking the system's event log to see if there's anything logged about TCP/IP or NIC connectivity events. Good luck, this one can be a bear. - William Fields ISO error means that there is index corruption, likely caused by those network disconnects. The operating system and/or network hardware is your primary suspect. VFP can't really be expected to compensate for hardware and OS-level services that are intermittent, short of a major re-write of your data access logic to open, write and immediate close every table. Calling in an experienced network engineer could speed the solution, or you can try isolate the problem to a single machine. -- tr Sorry, but I don't think index corruption has anything to do with the ISO error, although the error may certainly cause corruption. Every time my users have hit the ISO, the immediate solution has been to just restart the application, and every user

I have a program (EXE)install form, mabe 6month and working perfectly. Visual FoxPro 6.0, Then, for no apparent raison, wont run anymore. the error is "Invalid seek offset (Error 1103)".I replace all data with fresh new database/tables/index that I know is good. And the EXE did not work. same error.I recompile EXE with original sources, replace it.... same error. Want more? I dont use any SEEK in this application???The only way I found to fix this error is to recompile the source code directly on the machine. Then it works again??I can't install VFP with source code on all machine how wanna use this EXE program??Any idea? I can't find any solution about that on the web... feel free to send me any suggestion.Martin RE: Invalid seek offset (Error 1103) DSummZZZ (Programmer) 2
