VB Placing Letters in a Dynamic Text Field Trigger an Event?


I’m a newbie creating a simple (so I thought) program using Visual Basics and Flash CS3.

I am trying to get Flash to load and play a movie clip when Visual Basics places a letter “c” in a Dynamic Text Field in Flash.

I got Flash to display the letter “c” Visual Basics placed in the dynamic text feld, but how do I get Flash to see that letter as a variable? Also, once it sees it as a variable how do I get it to trigger an event? I don’t want a mouse click or keyboard click, I just want Flash to load the appropriate movie clip and play it once Flash receives the letter. Is this possible?

If anybody can help, I would appreciate it. Thank you.
