Read a long string (of up to 1024 characters) from a single cell
[C++]
BOOL GetLongString(
   CString& strText
) const;
If the function succeeds, this will contain the entire string contained in the target cell.
Returns TRUE if the function was successful, FALSE if it failed.
            The function can fail if the CXlOper does not contain a reference to a single cell,
            or if it cannot be run in Excel at this time.
This function retrieves the entire string contained in a cell, even if the string
            contains more than 255 characters. The calling object must contain a reference 
            to a single cell.
