This project is about making a winforms sample using the Library TLSharp [url removed, login to view] or the source can be found at [url removed, login to view] to be able to send messages to several different phone numbers. The sample must contain the following functionality:
1) ONLY AUNTHENTICATES 1 TIME and uses the DAT file that the library produces for ALL following authentications, ONLY when the file is corrupted of missing should the sample have to authenticate again.
2)Sample is able to send Message to any Person on the Telegram Contact List
3)All settings like Hash Key, APP_ID, authentication code etc must be loaded from the GUI and texboxes
4)When authenticating the first time there will be a timer controlled by the UI that will give you the chance to setup how many minutes the timer should wait before doing the authentication and give you time to receive the Auth Code from telegram so you can place it on the UI so the Authentication works properly.
5) The sample will have a function you can call with a phone number and a text message and send that message to that phone number.
6)If the application sample is terminated when is executes again will automatically start the session and be ready to send messages to any of the contacts in the contact list
