HXTT DBF
DBF driver and foxpro record locking

Hello,

I have a question about the special locking mechanism implemented in the DBF driver (the virtial column "_LockFlag_").
My question is, does this mechanism work with native locking from a foxpro application or is it only working between applications that use the DBF driver on the same database?

In other words, when a foxpro application locks a record, and a java application inspects the _LockFlag_ column, will this return true?
Same for the the opposite direction, when the _LockFlag_ is set in a java application, will the foxpro application see the record being locked?


Thanks in advance,

Rob Gansevles

Yeah. _LockFlag_ is a virtual column for programming lock, and is not necessary if you don't care for programming lock.

You need lockType=Foxpro connection property. With it, HXTT DBF and Foxpro applicatgion will see lock each other.
