Hi

I am trying to find out the size of a Microsoft Access Table in VB. I am using the following code.


        Dim cnn2 As OleDbConnection = New OleDbConnection()
        Dim cmd As OleDbCommand = New OleDbCommand()
        cnn2.ConnectionString = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=\\server\file\News.mdb"
        cmd.CommandText = "select count(*) as c1 from Headline"

        cmd.CommandType = CommandType.Text
        cnn2.Open()
        newrow = cmd.ExecuteNonQuery()


and getting the following error

System.InvalidOperationException: ExecuteNonQuery: Connection property has not been initialized.

Is there another way of doing this or am I on the right lines

you have not associated the Connectin object with the Command Object.  Try it this way:

        Dim cnn2 As OleDbConnection = New OleDbConnection( "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=\\server\file\News.mdb")
        Dim cmd As New OleDbCommand(cnn2)

        cmd.CommandText = "select count(*) as c1 from Headline"
        cmd.CommandType = CommandType.Text
        cnn2.Open()
        newrow = cmd.ExecuteNonQuery()
