I would like a checklist control which displays 3 distinct states. Yes, No, Unknown.
The box as a 'Tick' is obviously fine for the 'Yes' state. I would like the 'No' state to be displayed as an 'X' and
'Unknown' would be clear.
I have tried using the style lbOwnerDrawFixed but can see no way in the OnDrawItem event of drawing the
'Tick Box' differently.
A coded solution for this would be good but I am quite willing to consider a commercial product if you know of one.
