Ejemplo de conjunto de celdas (VB)
En este proyecto de Visual Basic se muestran los conceptos básicos del uso de ADO MD para acceder a los datos del cubo. Muestra títulos de miembro para encabezados de columna y fila y, a continuación, muestra valores con formato de celdas específicas dentro del conjunto de celdas.
