already wrote about this two weeks ago.
the client wil handle it this way:
1. check if address is within own address book -> green
2. if account exist within blockchain -> yellow
3. don't exist within blockchain -> red
simple visual control.
Thx. But what about after clicking "Send"? As I recall wrong sends happened after correct address was set.
you mean some kind of checksum?
as soon there is a difinition for this i am adding it for sure.
the above mentioned solution is of course very simple but effective as well.
within an option tab you can set the warning level. of course the user will get
an extra confirmation dialog for yellow and red after pressing send.
a realtime verification during typing depends on the gui-latency but as soon the
account number field lost focus the number is checked and gives a visual feedback.
