Question
ADODB Connection to a Microsoft Access DB from a VB 6 application
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.OL
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.OL
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 HEEEEEEEEEEEEEEEEEEEEEEEEE
