i have asp wesite with mssql db
the site is live and working
i want to convert few parts from the site to wpf appliction.
the main value of wpf app will be somthing like "invoice system"
manager will open wpf app and he will have some dashbord panel.
in ther he will see customers option and ther he can add new customer with details we will give later, and he can see list of customers and can edit/delete....etc.
in dashbord he also can see "payments" option and when he go ther so he can see year to work with and when he choose the year so he can see list of all customers apartments and then he can see 1-12 months in every row and when press on month so he can insert payment data and save.
in dashbord he can see "invoice" option and when go ther so he can see list of customers again and he choos year and then he see in table 1-12 months in every row and he see if invoice is done or not, if not so he see "generate invoice" and when press so it creat html template with invoice and send it to customer email.
also we want applciation will give 30 days for free and then user will need insert activation code for activate app for 12 month, and then activate again after 12 month is end, app close and he see page he mus contact to admin to activate.
activation code admin give him by email and it can work only on his app so he cant give the activation code to his frinds.
thats all options we want now
