I have a web browser accessing a SSL secure intranet.
The SSL isn't valid, but I need to accept it anyway.

I've read about

        ServicePointManager.ServerCertificateValidationCallback = ValidateRemoteCertificate;


        private static bool ValidateRemoteCertificate(
        object sender,
            X509Certificate certificate,
            X509Chain chain,
            SslPolicyErrors policyErrors
        )
        {
            return true;
        }

Open in new window


but it doesn't work! The error stay.
Can someone help me on this?

Can you clarify: who needs to accept it? The client receives the server's expired/invalid SSL, or the server receives the client's expired/invalid SSL?

mmm sorry but ServicePointManager.ServerCertificateValidationCallback does not work with the WebBrowser control, it work for example, for the System.Net.WebRequest class.
I remember see an article that talk about how to avoid the IE warnings... I will try to find it and post back...

1. Download the project from this link:
http://dl.dropbox.com/u/13237304/EE/WebBrowserControlDialogs.zip
2. Extract the zip file content to a folder.
3. Inside the WebBrowserControlDialogs folder, open the project file named: WebBrowserControlDialogs.csproj

This is a Windows Form application.

Ok, I found the problem, you will need to change the constants values in the StringConstants.cs file to match your environment language.

The key is WindowsInterop.WH_CALLWNDPROCRET_PROC, it uses these constants, so if you make the right changes to StringConstants you will be able to make it work.
