Download HV.CurrencyConverter here Version 1.47

Why this application?
To get current currency exchange rates in a WinForms application serves as an example for a WebService frontend.
HV.CurrencyConverter lets you convert 131 currencies in some amazing 17’030 combinations.
But this is not the main goal of this application.

Being a WebService-Frontend there have been implemented several patterns:
– request to WebService http://www.webservicex.net/CurrencyConvertor.asmx is made in a background worker to not freeze the main (GUI-) thread
– since a WebService may be out of order or cannot serve all requests, a local XML-repository with the latest rates is maintained (in the user’s roaming profile)
– a second background task skims all active currencies in the dropdownlists once a day to have at least one almost current rate if no update cannot be made


– only unzip the executable with its config file
– if your AntiVirus gets mad (because EasyDataEdit accesses a WebService on the Internet) and swallows its executable, please don’t be afraid and recover it from your AV’s quarantine area.
