Hi,

My application seem to be working after I recompiled my VFP6 application
to single thread and single instance as I am told VB6 is single threaded.
It work most of the time, but occassionally, it just don't work, it just
halt my application. For my application written using VB6, it will on
startup initialize the class and will called the dll function occasionally.

Like

set foxdll = new foxdll

foxdll.reindex()

Please kindly advise me on this issue. Thank a lot.
