I don't think VFP can do multiple threads. Having said that, I could be wrong. There is the MTDLL. You might want to look at using wmi code to expose that. Craig Boyd has some on his blog and a link to some others.

Is there some way to monitor the task manager? That'll show you if the process is running as 1 thread or two. I'm thinking that the SQL and VFP may run async at times. -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Larry Bradley Sent: Saturday, February 17, 2007 10:24 AM To: [email protected] Subject: Dual-core issue? I've a problem I THINK might be a dual-core issue. I've read the "buffer overrun" threads. Environment: A new dual-core 2 gig machine at a client site. Runs Win2K SP4, and VFP9 SP1. I converted an application from VFP tables to mySQL, and have a VFP utility that loads the mySQL tables from the VFP tables to get things started. Uses SQL passthough. Uses the mySQL ODBC 3.51 driver. I have no problems at all on my development machine; there are no problems if I run the upload on another machine on the network at the client site. However, on the dual-core machine, the SQL INSERTs that I use to load the tables fail sometimes with SQL SYNTAX errors. mySQL complains about there being an error in the SQL statement, and the error message it sends back shows a corrupted INSERT statement. It does not happen on the same record each time - it is random. And if I simply re-issue the INSERT, it works. I modified the program to do retries, and I can upload the tables this way. On a 15000 record table, I might get 30 errors that work when retried. I did some other tests - I created a remote view, and then updated the table this way - no problems - perhaps VFP is doing retries. I am limiting memory via SYS(3050) to around 24 meg, just as a test. On ONE occasion I got the dreaded "Buffer overrun" message from the C library. I also got this message once on my home machine. However, both machines are running SP1, which supposedly fixes this error. Any thoughts? Is it possible to disable part of a dual-core machine via the BIOS? (This is an ACER machine, which I think uses an AMD chip set). That would be the proof. Thoughts, anyone? I have no idea on how to solve this one.
