Hello,

In the NMCUSTOMDRAW strcuture that is passed with the message
there is a member lItemlParam, which contains the lParam data
passed when the list item is added to the list view.


You can use this lParam to define either a pointer to some
object, like a string with the contents of the list item
(see also LVN_GETDISPINFO/LVN_SETDISPINFO),
or a COLORREF value to be used when painting the item.


If the text of the items are dynamicaly changed, and you want to reflect 
this, you can put in the lParam member the index of the item,
and when painting, you can use that index to retrieve the text.
