I need a Windows application that does the following:
1) Get plaintext content from my webpage every minute, this is the price for something. If the price is different from the last notified price by + or - 5%, then pop up a tray notification that shows the new price.
Example: Price is $50
1 minute later: $51 (not enough)
2 minutes later: $52 (not enough)
3 minutes later: $52.5 - show tray notification
4 minute later: $57 - show tray notification
5 minutes later: $52 - show tray notification
This would get the price from a script on my website. The output of the script is just a number, like "[url removed, login to view]".
2) Check if a file exists, and if it exists then POST it to a page on my server. I will handle the file, it is just the settings for this app.
