Thanks Cetin

That really cleared that up for me. I am sticking to ODBC.

>>Help I am confused. I have read that OLEDB is supposed to be faster than ODBC so decided to try my hand at it.
>>
>>My code is:
>>cStr = [Provider=SQLOLEDB.1;Integrated Security=SSPI;Persist Security Info=False;Initial Catalog=;Data Source=]
>>ox=SQLSTRINGCONNECT(cstr)
>>
>>But every time I try this a window pops up "Select Data Source" and asks me to define a data source with the File Data Source and Machine Data Source Tabs.
>>
>>In ODBC I used this:
>>
>>cSql=[Driver={Sql Server};Server=;Database=;Int Security;]
>>oConn=SQLStringConnect(cSql)
>>
>>This worked every time without popping up any window.
>>
>>Am I doing something wrong here or is OLEDB to be used only with ADO? Do I have to create this DataSource on every client that connects using OLEDB?
>>
>>Could someone please enlighten me as to how I can use OLEDB instead of ODBC while NOT using ADO, to get a connection to a SQL Server 2000 database?
>>
>>TIA
