Prompt for username and password using Microsoft SQL Server ODBC Driver
Connection string
This Microsoft SQL Server ODBC Driver connection string can be used for connections to SQL Server 2000 and SQL Server 7.0.
This one is a bit tricky. First you need to set the connection object's Prompt property to adPromptAlways. Then use the connection string to connect to the database.
oConn.Properties("Prompt") = adPromptAlways
oConn.Open "Driver={SQL Server};Server=myServerAddress;Database=myDataBase;"
