Example

This code fragment traverses a Views collection to find the class of each view object it contains:

Dim colViews 
Dim objView ' could be any type of view object 
If colViews Is Nothing Then 
  objResponse.Write "Need to set the Views collection" 
  End 
End If 
For Each objView in colViews 
  strIndex = str(objView.Index) ' get view's index as a string 
  If 9 = objView.Class Then ' CdoClassTableView 
    objResponse.Write "View " & strIndex & " is a table view" 
  ElseIf 12 = objView.Class Then ' CdoClassCalendarView 
    objResponse.Write "View " & strIndex & " is a calendar view" 
  Else 
    objResponse.Write "Unknown view type: class " & str(objView.Class) 
  End If 
Next
