App height is bound by the stage size. It sounds like you actually want to change the player's object size in the browser which requires javascript and ExternalInterface

My app has a tree menu to the left and product thumbnails on the right. I want to increase the height of the application depending on the number of rows displayed in my product thumbnails. (The goal is to be able to scroll with the browser instand of scrolling inside a VBox) I have a appHeight property in my ModelLocator class. This property is changed when the product's dataprovider change. Here is the structure of my application <mx:Application ... height="{modelLocator.appHeight }"> <mx:HBox> <mx:Tree height="{this.height}">...</mx:Tree> <mx:VBox height="{this.height}">...</mx:VBox </mx:HBox </<mx:Application> This is the way i think it should work but it seems that i can't acheive what i want with this...the height does not change at all and i think there is a limit to the height of the application because if my heigh is 2000 or 4000 i don't see any difference... Please help!
