Error connecting to access database from VS 2017 RRS feed

  • Question

  • I am having an issue connecting to an access database to upload some data from SQL in the access database. This process was working before but we have migrated to a new server and the process is no longer working.

    Here is my code:

           Dim g_objCn As New ADODB.Connection
           Dim g_strConnectionString As String = "C:\database\data.accdb"
           Dim connsql = New SqlConnection
            connsql.ConnectionString = "integrated security=SSPI;data source=sqlserver;" &
                                        "persist security info=False;initial catalog=MainTables;MultipleActiveResultSets=true;"
                g_objCn.Provider = "Microsoft.ACE.OLEDB.16.0"
                g_objCn.Properties("Data Source").Value = g_strConnectionString
                g_objCn.Execute("INSERT INTO [C:\database\data.accdb].tblData (id, FacN, LName,FName)" &
                                "SELECT id, FacN, LName,FName " &
                "FROM [tblData] IN '' [ODBC;Driver={SQL Server};Server=sqlserver;Database=MainTables;Trusted_Connection=yes]")

    I am getting the error below on the line g_objCn.Provider = "Microsoft.Ace.oledb.16.0". I have checked the new server and that library is there (aceoledb.dll). So I am not sure what I am missing.

  • The message is saying that g_objCn is not open. You need to add code to catch errors and to show relevant messages and other data when there is an error. You should check to see if g_objCn is open before using it.
