~ Sharing Knowledge ~
~ For Any One Who Wants to Learn ~
On few requests, I have made an an PPPoE Dialer program in Visual C Sharp. This code/program can create / dial a broadband pppoe connection on Windows base Operating System. I have added many functions according to the local requirements. It was all built for my local lab testing purposes therefore there is a lot of room for improvements in it. Just to remind myself, I am not even a programmer, but a simple low level network support personnel. This is my first Try code in C# programming. It took me around one week to develop this code. Google search and Stack-overflow discussion forums helped a lot.
Very Sadly ! Most of the programmers / knowledgeable persons I know in my contact clearly denied to share any code / working solution with the public & advised me NOT to share such code freely/publicly, like the Joker once said in a movie scene.
“If you are Good at something, never do it for free“
But denying the above Joker statement, here I am. sharing my basic knowledge for anyone who wants to learn from IT ~
Components Used:
- OS: Windows 7 (64bit)
- Launching Pad: Visual Studio 2012
- Language: C Sharp (C#)
- Support Libraries: Dotras 1.3 (https://dotras.codeplex.com/)
- .Net Framework 4.x Library for Dotras
// Code Working Workflow Example //
- Username / Password Boxes: This must be filled first time, & the code will save it in registry, so next time the dialer is launched , it will be read automatically to avoid entering credentials again)
- Dial Button: which will basically dial the pppoe connection, it will also check if dialer is already connected.
- Disconnect Button: You know what disconnect means :). It will disconnect the dialer only if the dialer is really connected.
- Exit: This will close this application.
- Create internet Dialer Button: This will create pppoe dialer connection in Network Connections plus its shortcut on current user desktop, and if connection already exists, then delete, and re-create.
- Dialer LAN Status Button: It will check if the dialer is connected or not. Just to refresh the status.
- Internet Access Button: It will check ping to specific HOST (8.8.8.8) and if ping success/fails, set status accordingly.
- Balloon Texts / Notifications: When application is minimized to System Tray
- Auto Minimize: on connect / manual disconnect
- Tray Icon Menu Strip Menu Context to Show/Exit app. Example to show function.
- The code will keep checking the dialer status (every 5sec) /net status (every 10sec) and update eh text label accordingly.
I have NOT added auto – redial , but you can easily add it in raswatcher section ,if you like 
, i may be missing some other functions like data counters, will add more later, or you can add your own functions too.
I will update more later if get the chance…
Ok lets hit the Road , and view the code …

I will upload the complete package with code/debug/exe package later …
I am pretty sure that above code will help you in many parts when you will create your own project. I faced many challenges duet first time programming but your situation may be different if you have already working example in ahead of you
I will be more then happy if someone posts some more advance level of this dialer code for all.
