I wanted to see if I can write a simple application that uses a dictionary API to query a server somewhere (if I said that right). I have some ideas for a few more difficult apps so I wanted to start with this simple one.

I’m mostly using Expression Blend to create these apps.

The first thing I would like to know is:

- How do I use a wp7 icon (from the icon pack) as a clickable button? I have an input search TextBox, but instead of using a simple button control (for the click event) I would like to use the magnifying glass icon as the search button --something similar to how Bing (on WP7) uses the mic in the search box. How can I accomplish this?

The second thing I would like to know is:

- How is an API use in app? I found a few APIs/ RSS feeds and XML data sources that I would like to utilize in my future apps, but I’m not sure how to implement them.  
**EXAMPLE** : [http://api.somewebsite.xxx/xsomething=item1&sip=somethingelse](http://api.somewebsite.xxx/xsomething=item1&sip=somethingelse). I’ve read some about URI. What is this?

So basically, I would like to create an app that goes out to a server somewhere and fetch information based on a user’s keyword input and click event.

Please help!!!
