Custom Font Dialog/Selector for C# that filters out non true type fonts

[EDN Admin]

Since the inbuilt Font Dialog returns a Not a True Type Font Exception on selecting a Non True Type Font, Im trying to create a Custom Font Dialog using Font-families which filter out non true type fonts.
The Control is working perfectly but I need a size and style selectors for this dialog. Im posting the current code. Please help me add a size and a style selector to this. It could also be useful to you.
