CCheckListBox Sizing problem
I've created a CCheckListBox through subclassing, but I set the default font to 12 point size for the dialog that the original listbox resides in. The listbox is ownerdrawfixed and hasstrings.
When I populate the CCheckListBox everything seems to work until all the strings have been loaded and then I get an error in debug mode and it appears to have something to do with the minimum size of the items.
I can see the dialog on screen and all the strings are visible but the size of the checkbox is small (not the size I would expect for the 12 point font).
Since I have changed the default font size for this dialog do I need to implement an override of the measureitem method? Just as a side note, if I set the dialog default font back to 8 point (the original setting) everything works fine.

mblat - I looked at the article you recommended. And although it was for CListView I tried to implement the concepts.
I derived my own CMyCheckListBox class, and was able to get as far as creating the control and getting it to use the MeasureItem override. BUT... The drawitem was not valid, the strings were not drawn in proper relation to the rect they should have been in, they were drawn too low and overwritten by subsequent lines in the box.
Also, the check box could not be clicked, it simply wouldn't respond and the check box that was draw was still very small, it didn't seem to recognize the value supplied from measureitem at all. Thanks for the recommendation but it seems I need to locate some sample code that is specific to this problem.
