I wanna know how the normal connection is made by using that new ADO component.

I do this when I use that older DAO component:
MyData.DatabaseName = App.Path & "\database.mdb"
MyData.RecordSource = "SELECT * FROM Table"
MyData.Refresh

Could you give me an example.

Thanks in advance!

after applying the control to your form, open its property window and click on custom, where it says "use a connection string" click the build command button and choose the database of your choice.  then click next.  you wll be provided with options you may or may not need. you will also be able to test your connection by pressing the test connection button.  then click ok and you will be brought back to the original dialog.  there is a recordsource tab there where you can specify your SQl statement. it should be ready to go.

Hi
Try this Out.
To use ADO you have to use ADO's Connection.receordset Property.
Try the Following code.
First u have to creat DSN using  ODBC32(from Control Pannel)

Dim con as new Adodb.Connection
dim rs as new Adodb.Recerdset

con.Mode = adModeReadWrite
con.ConnectionString = "Provider=MSDataShape.1;Persist Security Info=False;Data Source=TestDSN;Data Provider=MSDASQL"
con.open

rs.open "Select * from TABLE",con

Good Luck.If any problem mail me at hijai23@yahoo.com

You can add an ADO Data Control component to the form (right mouse click on it after you have done so and selecte the ADODC Propertires) as suggested in the previous comment.. or.. Add a Data Environment (Vb Menu Projects).. or simply hardcode it.. <smile>.

----------------------------------
An example that opens a connection, opens a recordset, places three fields into three listboxes, and then closes the recordset and connection.

<----- Code Begin ----->

   Dim db As New ADODB.Connection
   Dim strConnect As String
   strConnect = "Provider=Microsoft.Jet.OLEDB.3.51;" _
      & "Data Source=c:\MyPath\MyFile.mdb"
   db.ConnectionString = strConnect
   db.Open
   
   Dim rs As New ADODB.Recordset
   rs.ActiveConnection = db.ConnectionString
   rs.CursorType = adOpenStatic
   rs.Source = "SELECT * FROM MyTable"
   rs.Open
   
   Do Until rs.EOF
      List1.AddItem rs!MyColumn1
      List2.AddItem rs!MyColumn2
      List3.AddItem rs!MyColumn3
      rs.MoveNext
   Loop
     
   rs.Close
   Set rs = Nothing
   Set db = Nothing

<----- Code End ----->
