How Do I Change TextInput Font?

Question

Hi,
I am using Adobe Flash CS5 and Action Script 3, but I am struggling to do something really simple (which means I am looking in the wrong place probably), I have 5 TextInput fields, I have added to the stage via the 'Components' option, but after discovering how to change the colour of the fields, I now want to change the font which appears when you type directly into the fields when the Flash movie is playing, however I can't seems to find this function.
I found a tutorial which mentioned going to the properties panel and then clicking 'Character, then 'Embed Font', but this maybe in CS4?
Any help would be great!

Thanks for your very quick reply kglad, I have followed the steps you outlined, my components instance name is 'ti', the font class is 'Harper', do I place this code within the timeline under actions or in the class I generated through the library, called Harper.as?
It is just I keep getting an error of 'access to undefined property ti' and also 'TextFormat is not compile-time-constant'.
Here is my class instance of Harper.as:
package  {
    import flash.text.Font;
public class Harper extends Font {
  public function Harper() {
  var tfor:TextFormat = new TextFormat();
var f:Font = new Harper();  // F is your font class name - see below
tfor.font = f.fontName;
tfor.color = 0xFF0000;
tfor.size = 18;
ti.setStyle("embedFonts",true)
ti.setStyle("textFormat", tfor);
   // constructor code
Many Thanks
