RE: VFP 9 Performance/Crashes
1. VFP9 Performance Our software (an ERP), which is written in VFP9, performs very poorly over the network from a virtualized Windows 2012 server to a workstation running either Windows 7 or Windows 8. There is a big delay opening some screens. However, when our software is run directly on the server, or over RDP, the same screens open and perform 10 times faster, or more. Something is making network performance very poor for the VFP software. There are no issues with other softwares, by the way. --- This may be completely unrelated, but a while back I had a performance problem like this with UltraVNC that was resolved by turning off aero Bill ___ Post Messages to: ProFox@leafe.com Subscription Maintenance: http://mail.leafe.com/mailman/listinfo/profox OT-free version of this list: http://mail.leafe.com/mailman/listinfo/profoxtech Searchable Archive: http://leafe.com/archives/search/profox This message: http://leafe.com/archives/byMID/profox/006d01cfec09$2baf8e20$830eaa60$@h2officesolutions.com ** All postings, unless explicitly stated otherwise, are the opinions of the author, and do not constitute legal or medical advice.

Part 2: I have never seen the crashes you describe. VFP 9 has been rock solid in that effect. Also, I would note that I have customers running the application on the Windows Server 2012 with RTD only. We are using TSPlus for as many users as you need to access the server. I agree that it is significantly faster than the workstation arrangement. -- Jeff Jeff Johnson j...@san-dc.com SanDC, Inc.

Wes: Frank Cabazon helped me regarding this exact problem. I have a lot of VFP 9 applications using the Visual Maxframe Professional framework. If the application was installed on a workstation and accessing files on another computer or server there are some registry entries that will fix this. I set them on the workstations and the server. (in many applications the "server" is another computer not running a server OS) They are: HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\MRXSmb\Parameters\OplocksDisabled = 1 (default = 0 or not disabled) HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\LanmanServer\Parameters\SharingViolationRetries = 0 (default = 5) HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\LanmanServer\Parameters\SharingViolationDelay = 0 (default = 200 milliseconds) You may have to enter the Parameter key and almost always have to enter the other DWords. As best I can tell, Microsoft uses oplocks to help their Office products open faster and only affects things like DBF files and Access files. It also appears that accessing a DBF on another computer always throws sharing violations even if they are shared on both ends. Adding these registry entries on all computers has solved the problem. I did also discover that the second and subsequent log ins to VMP prompted a VALIDATE DATABASE in a shared mode that really slowed things down. Point being that after entering the registry entries, look at the bottlenecks and see if you can improve performance. I can't thank Frank enough for helping me solve this. It made the difference between a frustrated user and a happy user! HTH -- Jeff Jeff Johnson j...@san-dc.com SanDC, Inc.

In sort of similar news, we very occasionally have a need to dredge up Foxpro for Windows 2.6 and the old 16-bit version of our software for a very few holdout customers, most of the time when they are finally upgrading. I have been using a 32-bit Windows 8 VM but for some reason it refuses to draw the display properly for Win16 applications. So last week I found myself installing and configuring Windows For Workgroups 3.11 under DosBOX, and then running the stuff under that. Never thought I'd be doing that again.
