Hello to all!

I'm designing a FoxPro application to administer on-line exams:

The text of the questions and possible answers will be stored in memo fields

I will need to apply some formatting to this text, for example;
- display words in bold
- display words in italics
- display words underlined
- dispaly words in different colors

In order to do this, I think an approach might be to store formatting codes within the text contained in the memo fields and somehow display the formatted text on the form.

That is what I have to resolve: Displaying the formatted text on the form!

Are there existing third party tools that do this? Any ideas on implementation?

Some of the challenges:
- lenght of text is unknown at design time
- lenght of text will go beyond the character limit of FoxPro labels
- ForxPro's Editbox control does not support formatting (as far as I know...FoxPro 9? :)

Possibilities I'm thinking about (If I don't find an existing, ready to use, solution!):
- Programmatic creation and position of labels on the screen, creating a new label every time formatting changes and everytime a carriage return should be performmed to remain within the borders of the form. Oh, and calculating these limits according to the size and type of the font!

As you can see, this is at the brainstorming stage...

So if any of you have any great ideas...I'm sure you all do....please share them with me!!!

Thanks in advance for your help!
