THE Connection in SQL 2000
It depends on what version of VB you are using, and what version of SQL Server you’re attempting to connect to. Also, there are several ways to connect from each version of VB to each version of SQL Server (ODBC, ADODB, DSN-less, etc.).
THE Connection in SQL 2000
Hi,
The method used to connect your SQL 2000 Database to Visual basic 6 program is called the ADO.NET. The connection can be made using the sql connection object. Here is a sample code to make a connection.
Imports System.Data.SqlClient
Dim CN As SqlConnection
CN = New SqlConnection( “Data Source=LCSServerSQL2005Server;Initial Catalog=RADdb;User ID=user1;Password=pw1”)
Here Data source is the server you are connected to and it can be found by navigating to My Computer -> properties-> Computer Name. Initial catalog is the Database name and User ID, password are the login details to access the sql database if you used any.
Here is the sample code to open the connection.
Try
CN.Open()
If CN.State = ConnectionState.Open Then
MsgBox(“Workstation ” & CN.WorkstationId & ” connected to database ” & CN.Database & ” on the ” & CN.DataSource & ” server”)
End If
Catch ex As Exception
MsgBox(“FAILED TO OPEN CONNECTION TO DATABASE DUE TO THE FOLLOWING ERROR” & vbCrLf & ex.Message)
End Try
