This looks to be my fault. The code I gave was to show HOW to retrieve the column name--you still have to do something to display it. GetName() returns a string that is the column name at index [i]i[/i]. You need to capture that value and then display it wherever you intend it to go. For example:

    string colName = Reader.GetName(i);

Please don't feel as though you have to accept the first answer you are given for a particular question. If something is unclear, feel free to ask for a clarification or to wait for another expert to participate. :)
