Thanks for your kindly reply.
But, in my Fox's Command Window,
=> ox = CreateObject("Dev99.Dev99")
=> ox.SqlTest()
---------> it's account is 'IUSR_VFUG_SVR'
It works well ( SQL Connected !!! )
But on the Web page, It Returns only -1 :(

Surelly I granted with IUSR_ account to my SQL Server.
( On Web Server suerlly granted Changed Right, and My COM Dll's Right )
But Why it does not work?
Why? why?....... :(

please send me a additional information. Thanks.
Lee.
