That was very close - I did not realize I needed to provide both the key and
the value of the hash to create the object-
eg I knew the HaskKey and its value so to create the dictionaryEntry I DO
THIS
Hashtable hTableProcedureTables = new Hashtable();
hTableProcedureTables.Add("A", "foo"); // key, value
DictionaryEntry dObj = new DictionaryEntry("A", hTableProcedureTables["A"]);
// adding key, then value.
