MS Access to KML Data Dump

Here's a script that helps to export KML files for Google Earth from Access tables. The idea is that you create a query with columns named "Latitude" and "Longitude" and any other columns you need. Open that query, and pass the recordset to this dumper. You also specify a file name, and a list of columns to use for the name and definition fields. The example is the testKML subroutine.
' rs is a regular recordset.  It must have a column named "Latitude" and another "Longitude".
' cols is a string with comma-separated column names that will be exported with the data.
' The first column is the title, and the rest form the description.

And here's the code for the file dialog box helper.
Function cmdExtFileDialog(ext As String) As String

'Requires reference to Microsoft Office 10.0 Object Library.

   Dim varFile As Variant
   Dim path As String
   Dim filename As String

   'Set up the File Dialog.
   Set fDialog = Application.FileDialog(msoFileDialogSaveAs)
   With fDialog
      .AllowMultiSelect = False
      .title = "Save As " & UCase(ext) & "  File..."
      If .Show = True Then
         path = .InitialFileName
         filename = .SelectedItems.Item(1)
         If (LCase(Right(filename, 4)) <> "." & LCase(ext)) Then filename = filename & "." & ext
         cmdExtFileDialog = filename
         Exit Function
      Else
         Exit Function
      End If
   End With
End Function
