INSTRUCTIONS FOR DESIGN OF THE PLATFORM VERSIONS OF THIS DIALOGUE

(1)	implement runModal(); at the moment we display a single listbox

(2)	m_iEncCount will tell you how many list entries there will be; 
	the encoding strings are then in m_ppEncodings (already sorted)

(3)	use _setEncoding() to set the member variables in response
	to the user selection when the dialog is closing.
