Re: Provide a link to a secure website from a WinForms application

Sounds like you're trying to have the application log the user into the site by bypassing the site authentication from your application. If someone managed to get their hands on the software the potential for damage to your business is high since they're using your account. But that's just my opinion.

I can't think of any way to have the user automatically logged into the site if it's being done through a POST method when you're using IE. If it's a GET method you could very easily just put it in the URI you're having IE connect to, but again - you're exposing your account information for all to see which is just plain irresponsible.

Thanks for the answer.
This opens the default browser but it doesn't logon the user automatically. It simply pop ups a dialog for username and password. (Like they open their browser and enter the location manually). I should be able to pass those credentials in the header of the request so they are logged on automatically.

Those classes you're using are for making your own browser application, not starting an instance of Internet Explorer.

If you're wanting to start up IE and have it navigate to that page use the System.Diagnostics.Process class.

Process.Start("http://www.yahoo.com";); or whatever URI you're wanting the browser to navigate to. This will use whatever their default web browser is currently set to on their machine.

If you do want to force IE to be used as the browser:
Process.Start("C:\\Program Files\\Internet Explorer\\iexplore.exe", "http://www.yahoo.com";); will accomplish that. I would suggest checking the registry to determine where IE is installed at rather than passing in a hardcoded path like I did, otherwise when the process is being started an exception will get thrown that it cannot find the file specified if IE is not there.

Hi,
I'm struggling with the following problem.

I have a WinForms application (.NET 2.0) where the user can lookup information on companies. In this application, I have to insert links to a third party website which has detailed information of that company. Normally, this website requires a username and password to logon. We got a username and a password from the supplier and they gave us an URL with which we can login directly using a TVA-number as a parameter in the URL. The credentials are to be passed as basic authentication in the http-header.
So, I found out I need to add the following headers:

- WWW-Authenticate : Basic realm="xxx"
- AUTHORIZATION: Basic xxx (where xxx is the base64 encoded username:password string)

I tried a lot of stuff but I can't figure out how to do this.
Using a WebBrowser control from inside the application is not an option. The user has to use the Internet Explorer.

I tried it with a separate website which is running on our webserver. I provided a link in our application which simply links to our website. This website redirects to the third party website but I can't add the necessary stuff to the headers. I'm still getting the inputdialog for a username and password. I installed HTTPDebuggerPro to look at the outgoing headers and the authorization header isn't in it.
When I debug my application I noticed I'm getting an exception (NotSupportedException) on the headers collection stating I need to be in IIS pipeline mode.

When I use a HttpWebRequest and a HttpWebResponse, I get an OK. But what to do next? At that moment, the user still has not an IE in front of him with the information.

Any help is appreciated.
Thanks,
Bart
