RegEx is inappropriate. You can use LinqToXML if your needs are simple and you don't want to use HTMLAgilityPack.

In the designer view of the form (not the code-file), click on the top of the form. In the properties windows, the form itself will now be selected. Amongst all properties of the form, you have one which is called AcceptButton (my mistake, I gave you a wrong name); set this one to the name of the OK button (you can select it). When that is done, you no longer need to write an event-handler (a method) for the button's click event; the framework will wire up everything and on click of the button the form will be hidden and return DialogResult.OK.
Learning is much easier and fun when people like you guys, help people like me out. I was ripping my hair out yesterday trying to figure out how to a value from one form to another.
Is the code that Phil.o supplied classed as an event?
You mentioned above that - Delegates aren't "the best way" to pass variables back, Events are (which use delegates, but hides the complexities from you).
No - that's just using ShowDialog to display Form2, which causes the Form1 code to "freeze", waiting for the new form to close before executing any more code (this is technically called a "Modal Form" but you don't need to worry about it).
There is also Form.Show which returns immediately, and that type needs Events to "Know" when data is available for Form1 to process. Follow the link I gave you, and you'll find a download of a source project that shows it all working with Show.
If you are going to use Events - and it's a good idea, .NET is built on the buggers - then also have a look here: A Simple Code Snippet to Add an Event[^] - it makes it a lot easier to create them in your own forms and other classes.

I want to write a PowerPoint addin that adds a button to the screen during the actual presentation time (rather than editing time) and then draws output on top of the presentation over top the presentation. The point is to pick a random person from a registered audience and display their name.
1. Is this kind of thing possible?
2. I know there are interop pages available online. Does anyone have any quick pointers as to what part of these documents I should look at for presentation event handlers (such as a slide change) and stuff like that? Perhaps how to draw a GDI+ object to a slide? (and remove that drawing upon a button click)?
