<p>When using the .NET WebBrowser control how do you open a link in a new window using the the same session (ie.. do not start a new ASP.NET session on the server), or how do you capture the new window event to open the URL in the same WebBrowser control?</p>

I just spent an hour looking for the answer, so I though I would post the results here. You can use the SHDocVwCtl.WebBrowser_V1 object to capture the NewWindow event.

```
//-------------------------------VB.NET Version:-------------------------------

Dim WithEvents Web_V1 As SHDocVwCtl.WebBrowser_V1

Private Sub Form_Load()
    Set Web_V1 = WebBrowser1.Object
End Sub

Private Sub Web_V1_NewWindow(ByVal URL As String, ByVal Flags As Long, ByVal TargetFrameName As String, PostData As Variant, ByVal Headers As String, Processed As Boolean)
    Processed = True
    WebBrowser1.Navigate URL
End Sub

//-------------------------------C# Version-------------------------------

private SHDocVw.WebBrowser_V1 Web_V1; //Interface to expose ActiveX methods

private void Form1_Load(object sender, EventArgs e)
{
    //Setup Web_V1 interface and register event handler
    Web_V1 = (SHDocVw.WebBrowser_V1)this.webBrowser1.ActiveXInstance;
    Web_V1.NewWindow += new SHDocVw.DWebBrowserEvents_NewWindowEventHandler(Web_V1_NewWindow);
}

private void Web_V1_NewWindow(string URL, int Flags, string TargetFrameName, ref object PostData,string Headers, ref bool Processed)
{
    Processed = true; //Stop event from being processed

    //Code to open in same window
    this.webBrowser1.Navigate(URL);

    //Code to open in new window instead of same window
    //Form1 Popup = new Form1();
    //Popup.webBrowser1.Navigate(URL);
    //Popup.Show();
}
```
