I have a tableadapter fill query that needs to be made more efficient (it takes too long to load images). I need a background worker integrated to speed up this process.
I sell this software and a buyer would purchase a license thru paypal. I need to connect my existing sql server database table to paypal so that when a user purchases a license - a variable "paid" or "verified" is entered into my database into a certain row. I think one approach would be to load the paypal payment page in a webbrowser control and the user can pay while logged into my software. Because the user is logged in you will have access to his user_uuid and this uuid can be used to enter the variable in the correct row.
