ADODB Connection to a Microsoft Access DB from a VB 6 application

Asked by wilsoada in VB Database Programming

Tags: access, connection, vb, adodb

I am trying to set up my first connection using ADO from VB6 to a Access database.

Some settings:
I have the Microsoft ActiveX Data Objects Recordset 2.7 Library and the Microsoft ActiveX Data Objects 2.7 Library references both selected in VB6 for the application

The Access database is created and closed and the table names are correct

I am trying to open a connection to the database and then retrieve a simple record from the database.

Connection:

Global Conn As New ADODB.Connection
Public Sub DBConnect()
    Dim Cmd As New ADODB.Command
    Dim RS As ADODB.Recordset
    Conn.ConnectionString = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source = C:\Program Files\Microsoft Visual Studio\VB98\Database Editor\DBEditor.mdb"
    Conn.Open
   
    Cmd.CommandText = "MT"
    Cmd.CommandType = adCmdTable
    Set RS = Cmd.Execute

Error:
The above code gives me an error RunTime Error: 3709 The connection can not be used to perfrom this operation. It is either closed or invalid in this context.

So I tried a new type of query using SQL and got the same error.

Global Conn As New ADODB.Connection
Public Sub DBConnect()
    Dim Cmd As New ADODB.Command
    Dim sqlString As String
    Dim RS As ADODB.Recordset

    Conn.ConnectionString = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source = C:\Program Files\Microsoft Visual Studio\VB98     \Database Editor\DBEditor.mdb"
    Conn.Open
    sqlString = "SELECT * FROM MT"
    cmd.CommandText = sqlString
    cmd.CommandType = adCmdText
    Set RS = Cmd.Execute
End Sub

I get the same error message again. I think something is wrong with my database even though it connects with no error's HEEEEEEEEEEEEEEEEEEEEEEEEEEELP!!!!!!!!!!!!!!!!!!!!!!
