System.Windows.Forms.WebBrowser open links in same window or new window with same session

Question

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 y

Answer 1

Slightly cleaned up version of Greg's answer. It modifies the passed-in control's behavior rather than relying on a global variable. Usage:

InlinePopups(webBrowser1);

Code:

// interface to expose ActiveX methods
private SHDocVw.WebBrowser_V1 Web_V1;
private void InlinePopups(WebBrowser browser)
{
    // hooks to force new windows to open in the current instance
    Web_V1 = (SHDocVw.WebBrowser_V1)browser.ActiveXInstance;
    Web_V1.NewWindow += new SHDocVw.DWebBrowserEvents_NewWindowEventHandler((string URL, int Flags, string TargetFrameName, ref object PostData, string Headers, ref bool Processed) =>
    {
        Processed = true; // stop event from being processed

        // open in the existing window
        browser.Navigate(URL);
    });
}

Still needs the reference to %WINDIR%\system32\shdocvw.dll, of course.
