how to prevent flash from scaling / resizing my content in a web browser?

I have finished my flash game, but when I used web Browser such as Chrome or FireFox to 开发者_StackOverflow社区run it, it enlarged my game to full size of the browser. Is there anyway( in AS3 script) that I could prevent this from happening as well as hide the symbols that their sizes are bigger than my default size defined at the document property panel?

You can prevent your application to be resized by setting stage.scaleMode = StageScaleMode.NO_SCALE; in your main application constructor. There are as well other scaleMode values available. See the docs.
