This is an example of a working DSNless connection to a remote database using ADO

'Establishing DSNless Connection
strConn "PROVIDER=SQLOLEDB;SERVER=192.168.0.5;uid=xxx;pwd=xxx;database=xxx;"
Set dbConn = CreateObject("ADODB.Connection")
dbConn.Open strConn
Set rs = dbConn.execute(strSQLQuery)

Doing it without the ADODC control but referencing ADODB should work

Regards
Andrew

Try this
....'Reference the ADODB library for early binding
Dim Conn as New ADODB.Connection

Conn.Open "Driver={SQLServer};Server=YourServer;Uid=sa;Pwd=;Database=YOURDB"

....
...later..Sachin

I have tried the same connection string but it doesn't work with Oracle database.
What could be the problem is that, Oracle uses different protocol. What could be the way out.

Any suggestions are welcomed.

use this
Conn.Open "Provider=MSDAORA.1;User ID=sa;Data Source=SERVERNAME;Persist Security Info=False"

you can open VB add ADODC control on form and build Connection string from that & then copy & paste the string

Have you installed the appropriate Oracle drivers.
ADO needs the correct drivers for each database.
