dear devart :
I have some question.

environment:
D2007
MSSQL200
UniDAC 2.0
RO sdk 5.0.37

my question:
1.
I use TUniConnection under main form and threads mode.
so I use only create one TSQLServerUniProvider in the main form,or every thread must create one TSQLServerUniProvider?

2.
CoInitialize and CoUninitialize must typed in the thread mode and main form,or it only typed in the main form?


thanks!

1. You don't need to create TSQLServerUniProvider. Only add the SQLServerUniProvider unit to the uses clause of the unit where TUniConnection is created.

2. You should execute the CoInitialize function in the thread, where connection to SQL Server is established.
