Cellset Example (VB)

This Visual Basic project demonstrates the basics of using ADO MD to access cube data. It displays member captions for column and row headers, then displays formatted values of specific cells within the cellset.

Private Sub cmdCellSettoDebugWindow_Click()
Dim cat As New ADOMD.Catalog
Dim cst As New ADOMD.Cellset
Dim i As Integer
Dim j As Integer
Dim strServer As String
Dim strSource As String
Dim strColumnHeader As String
Dim strRowText As String
