How to load/save file from Isolated Storage
You can save and load configuration information in the Isolated Storage of the app, to do that you can use the next functions from your Javascript files:
window.external.notify("SaveConfiguration(aStringWithTheData)";
window.external.notify("LoadConfiguration()");
You can serialize your configuration information in a string and store that with the
SaveConfiguration call.
If you wan to get that info, write a function called
setdata in your javascript that the
LoadConfiguration will call passing your saved string.
