You have set yourself a very difficult target. Normally text which is meant to be formatted with bold or underlined sections contains "tags" within the text which define the formatting required. HTML is a formatting language that is built upon such tags.
Your text does not include any formatting information; in that case you need some other method to determine which words need to be treated differently. Looking at the text in your database the best method that I could suggest would be "If a word is written completely in uppercase then show it in bold type". However I would be surprised if this rule serves all of your requirements.
If that rule is indeed what you want then every time you put text into a text box you will have to analyse the text string word-by-word and test if each word contains only uppercase letters. Then, if you are using CSBuilder or BBCodeView you will have to build a new string, word-by-word, inserting formatting information before you display the string in a view.
This will be quite difficult to do, even if you already had some coding experience, and I suspect that you do not. You would almost certainly want to use Regex matching, for example. I have looked at the problem for nearly an hour to see if I could find a way to make the task fairly simple, but I could not.
