[IRtdServer interface method] ConnectData(TopicID, Strings, GetNewValues) [Description] 
This method is called whenever Excel requests new topics from the RTD server. The TopicID parameter is a required Long value that represents a unique, arbitrary value automatically assigned by Excel (for example, "34") that identifies the topic. The Strings parameter is a required array of one or more Variant values that the user enters into the RTD function to uniquely identify the topic. This Variant array should always be an array of String values. The GetNewValues parameter is a required Boolean value; True if new values are to be retrieved. Leave the GetNewValues parameter alone if you want Excel to use the previous value that it had saved with the Excel spreadsheet.
