Hi,

I'm developing a BlackBerry application. I need advice on following features and tips on how to realize them:

1) How to Invoke a blackberry application from e-mail?
Explanation: we intend to send an e-mail to BlackBerry Mail application that consists of a URL, when clicked on it, should invoke the specified application on device (not native, custom developed application) and pass the parameters.

2) How to develop a home screen widget that displays alert counter (you have X number of alerts), when clicked on it it should invoke the corresponding application.

3) How to develop controls such as Bar, pie, line charts?

4) Zoom In & Zoom out of Images

5) Audio/Video capturing from application

6) Lost or stolen device wipe off

Appreciate any help, related links and info.

You might want to post this in the developer forum.
