I am trying to find the fastest way to populate a combo box with data that's in a SQL Server DB.

I usually create a recordset and pass along a stored procedure as one of it's parameters to get the desired results(see below)

Set rc = New ADODB.Recordset

    If IsMissing(Company) = True Then
        SSQL = "EXEC [BuildActivityList] "
    Else
        If IsMissing(WeekOf) = True Then
            SSQL = "EXEC [BuildActivityList] '" & Company & "'"
        Else
            SSQL = "EXEC [BuildActivityList] '" & Company & "','" & WeekOf & "'"
        End If
   End If

   With rc
        .ActiveConnection = cnStandByPay
        .CursorLocation = adUseServer
        .Source = SSQL
        .Open
    End With

    If rc.EOF = True Then
        BuildAccountDropDownList = ""
    Else
        Do While rc.EOF = False
            BuildAccountDropDownList = BuildAccountDropDownList & rc![Activity] & vbTab & Trim(rc![Description]) & "|"
            rc.MoveNext
        Loop
    End If

    rc.Close
    Set rc = Nothing

This works fine, but when the resulting recordset is big, it tends to slow down the displaying of the combo box.

I've also attempted to load all of the data as part of my start-up code(see code below), so I don't need to query the database, but using the .FIND method of a recordset is much slower than querying the database directly.

    SSQL = "exec [BuildActivityList]"

    With rsLawsonActivityCodes
        .CursorType = adOpenStatic
        .LockType = adLockReadOnly
        .CursorLocation = adUseClient
        .Open SSQL, cnStandByPay
    End With

    rsLawsonActivityCodes.ActiveConnection = Nothing

I was wondering if there was a way to combine the two, so that I could create a secondary recordset based on the records I loaded at start-up, that would only have the records that I wanted to loop thru while populating the combo box.

Thanks!
