Answer 1

What about using Application.ActiveCell.get_Address(true, true, Excel.AlReferenceStyle.xlA1, missing, missing) and then parse the result string or use a RegEx to get the column heading?

I simply used:

string location = Application.ActiveCell.get_Address(true, true, Excel.AlReferenceStyle.xlA1, missing, missing);
string tokens = x.Split("$".ToCharArray());
MessageBox.Show(String.Format("Column {0}", result[0]));
