In my website I am developing "simple messaging system".
I have 3 ASP controls on .aspx page, i.e., ListBox (that shows online users), multiline Textbox(to write a message) and Button("send" button, which sends message to the selected online users of ListBox)
I am unable to implement below requirement:
I have to select multiple online users from "ListBox", then type a message in multiline "Textbox" and click on "Send button".
These messages are temporary so can not be stored in Database. I have to store them using "Application and Dictionary class".
From these "Application and Dictionary class" I have to show the messages inside Pop up to the selected(from ListBox) online users.
I hope I made my requirement clear.
Please help me how to achieve this. I have no idea and I am a beginner in Asp.Net C#.
Please reply.
