The following procedure runs when the user clicks a button in a VBA user form. The procedure loops through the collection named Item Info and checks the Item Color property for each item. If the value is Red, the collection’s Remove method deletes the object indicated by the ID property:
Private Sub CommandButton_Click() Dim ItemCollection As DUOSObjects Dim ItemObject As DUOSObject Set ItemCollection = DUOSObjectsGet("Item Info") For Each ItemObject In ItemCollection If ItemObject.Properties.Item("Item Color") = "Red" Then 'Delete the object ItemCollection.Remove (ItemObject.ID) End If Next End Sub
