Removing swf

Hi,

Please pardon me, if i am not clear with my explanation.

I need to add a new swf, and remove the current one when i click on a button.

Adding a new swf, doesnt seem to be much of a problem, the problem lies in how can i remove the swf file.

In AS2, i most probably can use command like this.unloadMovie(); to get rid of the swf. And since, i am trying to script them in AS3, it leaves me pretty clueless on how to do that.

I tried, removechild(this); , which i thought will work the same for unloadMovie(); doesnt seem to work as well.

Would appreciate if you can give me any reference or tell me how i should do it. Thanks in advance. =)
