Hi all,

I have a general question about

Delete this.onEnterFrame

as a opposed to

this.onEnterFrame = null

Do these both do the same thing or will there be a difference

The code below, is it best to use  
[AS]delete this.onEnterFrame[/AS]  
or  
[AS]this.onEnterFrame = null [/AS]

[AS]  
logo\_mc.onEnterFrame = function() {  
this.\_alpha += 10;  
if (this.\_alpha\>=100) {  
this.\_alpha == 100;  
delete this.onEnterFrame;  
}  
};  
[/AS]
