I’m creating a flash-based login prompt for user name and password and I want to force the user names to be all caps. Is there a simple way to get this accomplished?

Thanks,

James

```auto
myTextField = myTextField.toUpperCase();

```

You’ll need an onChanged handler to get that code to work properly…  
[AS]myTextField.onChanged = function() {  
this.text = this.text.toUpperCase();  
};[/AS]
