Hi

I want to connect to my online SQL database  in my Excel 2007 Add-In in VB.net.
I used the code below to connect via VBA.
How do I change it to connect in VB.net?
What Imports do I use
Sub A()
    Call oAppend(Now, "yet more", 45)
End Sub

Public Sub oAppend(ByVal oDate As Date, ByVal oText As String, ByVal oNumber As Single)
 
    Dim oSQL As String
    
    On Error GoTo EH
    
    Set con = New ADODB.Connection
    
    con.Open "Provider=SQLOLEDB;Data Source=196.220.411.247,1235;Network Library=DBMSSOCN;Initial Catalog=test;User ID=nmomashhjjk;Password=nnnmmm222;"

    Set cmd = New ADODB.Command

    'Check last ID ---------------------------
    
    Dim oSQL_lastID As String
    oSQL_lastID = "SELECT MAX(ID) FROM Table1"

    
    Dim Last_ID_Recordset As Variant
    Dim Last_ID_Integer As Integer
    Dim Next_ID_Recordset As Variant
    Dim Next_ID_Integer As Integer
    Dim intID As String
    
    With cmd
        .CommandText = oSQL_lastID
        .CommandType = adCmdText
        .ActiveConnection = con
        '.Execute
        Last_ID_Recordset = .Execute() 'this line returns a recordset
        Last_ID_Integer = Last_ID_Recordset(0)
    End With

This example is helpful as well

Imports System.Data.SqlClient

connetionString = "Data Source=ServerName;Initial Catalog=DatabaseName;User ID=UserName;Password=Password"
        connection = New SqlConnection(connetionString)
