c# with dotras - Status Box not updating automatically after dial connect/disconnect

  • OS: Windows 7 /64bit
  • Application: Visual Studio 2012 / C# and DotRas 1.3 Library
I am very new to c# or VS thing so please bear with me. After doing many hours R&D, I have finaly made a pppoe dialer program in C# / Dotras. This program have 3 main buttons
  1. Create /Add PPPoE Internet Dialer Connection in network connections , working fine
  2. Dial button, which connects the newly created dialer , working Fine
  3. Disconnect working fine
I have added StatuBox (using rasDialer1) where dialup events should appear as showed on dotras youtube video tutorial (which was for vpn, but my project is for pppoe dialer)

StatusBox Not updating the dialup events like connecting/password error/connected etc. This is the part where I am finally confused.

Following is relevant Code.
// Dial Button Action
private void button2_Click_1(object sender, EventArgs e)
using (RasDialer dialer = new RasDialer())
// I had to add below line to update statusTextBox Manualy , want to get rid of it by adding auto status update
this.StatusTextBox.AppendText(string.Format("{0}\r\n\r\n", "Connection in progress ...", "{0}\r\n\r\n"));
dialer.EntryName = ("pppoe2");
string username = textBox1.Text;
string passwd = textBox2.Text;
// If username is empty dont connect 
if (string.IsNullOrWhiteSpace(textBox1.Text))
this.StatusTextBox.AppendText(string.Format("{0}\r\n", "Cancelled. Cannot continue with username/password.", "{0}\r\n"));
MessageBox.Show("Enter username.", "Error", MessageBoxButtons.OK, MessageBoxIcon.Warning);
dialer.Credentials = new System.Net.NetworkCredential(textBox1.Text, textBox2.Text);
dialer.PhoneBookPath = RasPhoneBook.GetPhoneBookPath(RasPhoneBookType.User);
dialer.Timeout = 1000;
dialer.AllowUseStoredCredentials = true;
// start dialing, 
// If dialer connects successfully update StatuTextbox
this.StatusTextBox.AppendText(string.Format("{0}\r\n\r\n", "Connected."));
private void rasDialer1_StateChanged(object sender, StateChangedEventArgs e)
this.StatusTextBox.AppendText(string.Format("{0}\r\n", "Status Changed"));
private void rasDialer1_Error(object sender, System.IO.ErrorEventArgs e)
this.StatusTextBox.AppendText(string.Format("{0}\r\n", "STATUS UPDATE TEXT XYZ"));
private void rasDialer1_DialCompleted(object sender, DialCompletedEventArgs e)
this.StatusTextBox.AppendText(string.Format("{0}\r\n", "STATUS UPDATE TEXT XYZ"));
Any help would be highly appreciable.

I was able to make a basic level pppoe dialer with few additional functions according to my requirements. I have documented it just in case any one needs it .
