A. Setting the Description Property
Use the following code to set the Description property for a clsColumn object:
' Assume an object (dsoColumn) of ClassType clsColumn exists
dsoColumn.Description = "Number Sold"
B. Adding a Column to a Mining Model and Setting the Column Description Property
The following example creates a new column in the mining model and sets a number of properties, including the Description property:
'------------------------------------------------------------------------
' Add a new column to the mining model called Gender and relate this
' column to the Gender member property of the Name level of the
' Customers dimension. Declare that the data in this column is
' statistically discrete.
' Assume the existence of a DSO Level object, dsoLv.
'------------------------------------------------------------------------
'Add another column to the model.
Set dsoColumn = dsoDmm.Columns.AddNew("Gender")
'Identify the member property of the Customers dimension
'that this column is based on.
'Set the column's description for browsers of the schema.
Set dsoColumn.Description = "Based on the Gender member property " & _
"of the Name level of the Customers dimension."
Set dsoColumn.SourceOlapObject = dsoLvl.MemberProperties("Gender")
'Identify its type.
dsoColumn.DataType = adWChar
'Make this column related to the Customer Id column.
dsoColumn.RelatedColumn = "Customer Id"
'Identify this column as containing discrete data.
dsoColumn.ContentType = "DISCRETE"
