VBA in Access 2010 - Run-time Error 430 - sql

Question

I’m getting a Run-time error '430': Class does not support Automation or does not support expected interface" on this line of code Set Me.lstResults.Recordset = rs or this Set Me![frmM_SearchForDocumentsSubForm].Form.Recordset = rs. I am trying to get the ADO Recordset based on a SQL stored procedure to appear in an unbound Listbox or Subform of an Access form. I’m on Win 7 Machine using Access 2010 connecting to SQL Server 2008:
On_Click event:
Private Sub cmdRun_Click()
'On Error Resume Next
Dim strSQL As String
'Stored procedure + parameters called from form
strSQL = "Exec sqlsp_searchalltables " & Me.txtTables & _
", " & "'%" & Me.txtSearchTerm & "%'"
OpenMyRecordset rs, strSQL
'debug - view procedure
Me.lblQuery.Caption = strSQL
Me.Repaint
Set Me.lstResults.Recordset = rs
'or this
'Set Me![frmM_SearchForDocumentsSubForm].Form.Recordset = rs
End Sub
I found some solutions for this error on the web and tried all of them to no avail. Most suggested checking the references which I did and verified.
I am able to successfully connect to the SQL server and have the results display in both a Listbox and Subform when I use DAO Querydef and a passthrough query or if I use this .listbox method:
With Me.lstResults
Do
strItem = rs.Fields("CLIENT_ID").Value
.AddItem strItem
rs.MoveNext
Loop Until rs.EOF
End With
I would prefer not to use the DAO method because I found I need the coding flexibility of ADO especially with connecting to multiple Recordsets in SQL. Thoughts?
FYI: My OpenMyRecordset public function in Module:
Option Compare Database
Option Explicit
Global con As New ADODB.Connection
Global rs As ADODB.Recordset
Global NoRecords As Boolean
Public Enum rrCursorType
rrOpenDynamic = adOpenDynamic
rrOpenForwardOnly = adOpenForwardOnly
rrOpenKeyset = adOpenKeyset
rrOpenStatic = adOpenStatic
End Enum
Public Enum rrLockType
rrLockOptimistic = adLockOptimistic
rrLockReadOnly = adLockReadOnly
End Enum
Public Function OpenMyRecordset(rs As ADODB.Recordset, strSQL As String, Optional rrCursor As rrCursorType, _
Optional rrLock As rrLockType, Optional bolClientSide As Boolean) As ADODB.Recordset
If con.STATE = adStateClosed Then
con.ConnectionString = "ODBC;Driver={SQL Server};Server=mysqlsvr;DSN=RecordsMgmt_SQLDB;UID=XXX;Trusted_Connection=Yes;DATABASE=RecordsManagementDB;"
con.Open
End If
Set rs = New ADODB.Recordset
With rs
.ActiveConnection = con
.CursorLocation = adUseClient
.CursorType = IIf((rrCursor = 0), adOpenDynamic, rrCursor)
.LockType = IIf((rrLock = 0), adLockOptimistic, rrLock)
.Open strSQL
If .EOF And .BOF Then
NoRecords = True
Exit Function
End If
End With
End Function

You definitely do not have to do the looping method to just to populate the listbox. I'm not familiar with the OpenMyRecordset command you used, but I suspect that something in its functionality is what is causing this error (i.e., it's not opening the recordset in a manner compatible with the listbox). This is how I connected to a local instance of SQL Server Express and was able to populate a listbox.
Dim cn As ADODB.Connection
Dim rs As ADODB.Recordset
Set cn = New ADODB.Connection
With cn
.ConnectionString = _
"Provider=SQLOLEDB;Data Source=localhost\SQLEXPRESS;" & _
"Initial Catalog=Northwind;Trusted_Connection=yes"
.Open
End With
Set rs = New ADODB.Recordset
With rs
Set .ActiveConnection = cn
.Source = "SELECT FirstName, LastName FROM Employees"
.LockType = adLockOptimistic
.CursorType = adOpenKeyset
.Open
End With
Set Me.lstTest.Recordset = rs
Set rs = Nothing
Set cn = Nothing
You will have to make sure that you have the Microsoft ActiveX Data Objects Library reference enabled in your project.
