my asp page display different resolution in different mechine,how can fix the resolution of asp page for all mechines same display resolution<

you shouldn't, that is the whole point of web pages, they SHOULD expand/contract to fit the browser, fixed width web pages is bad design practice<

Aesthetic arguments aside (for the record, I agree with HuwR - fixed width pages are evil), there's a practical side to this as well: do you really want the visitor with the uber cool 26" LCD to see a page that only occupies the 600px width you programmed in so everyone could see the same thing? Or if you went bigger, what happens to the poor bugger who's stuck at 800x600?<
