Windows 8 application Resolution

I have developed Windows 8 application. and when I try to run it , to test it on another laptop ; the design got worst and everything appear in bad way.(Fonts, images, ..)
Is that related to the resolution ? If yes How I can solve it ?
How was your app developed? Is this a xaml/cs app or html/js app for windows 8 store apps? Is it in the store yet or only testing? Are multiple resolutions supported?
You'll want to test out various resolutions to see how your app handles them. Two links to test out here with your application:
Windows Store app Development Snack: Simulator tips & tricks
Scaling to different screensre
Another area to check is pixel density. Follow the guidelines for scaling to pixel density to ensure your app looks great when scaled.

Tile Based UI inside windows 8 store app

I am creating window 8 store app that will run on windows 8 tablets,
In my application I want to give tile based UI,
Can any one guide, how will it be possible or is there any controls available like HubTile Control for WP7... ?
Thanks And Regards,
:)
Telerik has released the Windows 8 controls which includes the Hub tile as you mentioned for WP 7.
Check it out : http://www.telerik.com/products/windows-metro/controls/hubtile.aspx

is there something like a hubtile (WP7) in win 8 metro style?

i want to port one of my windows phone 7 apps to the windows 8 metro style plattform.
the problem is, that i need a element like the hubtile which i use from the silverlight toolkit for windows phone.
is there something equal in the windows 8 metro style platform? maybe open source like the silverlight toolkit.
i dont want to add the livetile outside my app, this is easy. i want to have something like hubtile for WP7 for win8. This means a tile which is inside my application.
If I'm right I'm planning to do the same task. I didn't find any reference of a control which performs like a HubTile. Thus, I decided importing the one from the Silverlight Toolkit (for Windows Phone). Luckily it worked almost smoothly, you can see my sample at:

you can work with the live tiles of course and in several ways. You can use badge notifications, toast notifications, and so on.
I'll suggest you to take a look to this documentation.
And also take a look to those two samples: App tiles and badge sample and Push and periodic notifications client-side sample
By the way don't forget to enable the features you need in the package manifest.
