Convert It 2.6 has now been posted at http://blogs.msdn.com/dglover/articles/category/11231.aspx.
"Convert It V2.2" for your Windows Mobile Smartphone
It runs on a Windows Mobile Smartphone with the Compact Framework V1 installed on it which include Windows Mobile 2003(inc SE) and Version 5 based phones!! As with the Smartphone SMSVoter application - no liability accepted, it's free and it does work:-)
As the name suggests is does conversions - it supports four types of conversions, each with up to 10 categories.
See these Installation Locations.
To install, download (and unzip if you downloaded the .ZIP file), connect your Smartphone to your PC via ActiveSync and copy the Cab file to "\Windows\Start Menu\Accessories" directory, once copied then from your Smartphone navigate to the the Accessories menu and click on it to start the installation process. The application will appear on the Start Menu.
General information on "Convert It" can be found here including:-
It's been written as a generalised "Ratio" converter, I've loaded up ratios for converting weights, distances and temperatures, but it's arbitrary, you could give it a ratio for "Pigs to a Pen" and it would convert it;-)
It also calls two Web Services, one for "Currency Rates" and the other for "Stock Quotes" - both services are provided by http://www.webservicex.net, and the results of this web services calls are saved locally for offline conversions.
An arbitrary base reference currency is set and then all currency data is gathered relative to that base reference currency.
The default base reference currency is Euros, so for example to convert "£1 -> US$" I first convert the £1 to the base reference currency, in this case the Euro and then convert the Euro to the US Dollar, sounds convoluted but it works and means that you can pretty much do any to any currency conversion offline - important when you are shopping with limited data network coverage and obviously it's quick as it's all local data and local processing!!
Surprise surprise the whole application is configured using XML - almost nothing has been hard coded in to the application (except for Celsius <-> Fahrenheit which needs a constant) and all setting can be configured by editing the applications XML files.
The application is dependent on the Catalogue.XML file which describes the Conversion Categories, their Type, Display Name and the name of the XML document where the ratios are defined.
See Convert It 2.2+ XML Schema Definitions for more information on the schemas.
I've got a blog in mind to write and it's basically what approach I take when writing applications for the Compact Framework. But it can be summarised as follows:-
