Win7 LAN Problem 1

[adit39]

Our app was written in VFP8 and we use DBI-Tech ctCalendar6,ctDate6,ctMday5 modules for appointment scheduling. Typical client is 1-5 user environment.

We now have clients upgrading to Win7 and have encountered the following scenario:

User1= Data Server if running M/U LAN
User2= Workstation

Computers are both Win7 64bit(default)
Problem exists with both 1GB ethernet switch and/or wireless router

User1 -Using INNO to install all program and data files to C:\APP and creating temp files in C:\APP\TEMP for fast reads / lookups.

User2 (LAN) - Using INNO to install all program files to C:\APP and creating temp files in C:\APP\TEMP for fast reads/lookups, pointing config.fpw to User1 data files

If running app single user, NO problem.

If User1 is running app, User2 runs normally until opening app. When user2 runs EXE there is 20-30 second delay before opening and/or changing tasks.

Reverse is also true if User2 is running app first and User1 subsequently runs the EXE.

Have had no problems previously on XP or Vista (32 bit)

I appreciate any opinions, suggestions or solutions.

Thank you,

Olaf, I honestly don't know. I have had trouble with registry settings on 64-bit computers. For that reason, I began changing my algorithms to write to both explicitly, that way it's never in question or a doubt. It has solve all of the issues I've had, but it may not be the correct solution -- just merely one that works.

Best regards,

Rick, it surely would be double safe to turn off oplocks in both 32bit and 64bit registry.

Indeed I already answered how to read 64bit keys via Foxpro at

That's german, but not the stackoverflow article:

I still go back to mentioning the export function of regedit. You can export keys you set at your dev machine into a reg file and instead of a form with a button to click, you give your users a reg file to double click. Not that much more effort to them, is it?

Bye, Olaf.
