Hi,

I have got a problem with the webbrowser control - IE Version 6.0.3790.0.  
You only have this version on Win2003 Server (all service packs installed)

The progam runs perfect with the "normal" IE Version 6.0.2900.2180 onto
WinXP, Win2000 -and- Win98/Me ;-)

Intension:
Use webbrowser control in a form and get calls from IHttpSecurity interface
if something is wrong with a certificate without GUI

My solution:
With AxImp /source I created the AxSHDocVw class and implement IHttpSecurity
and IServiceProvider
IServiceProvider is called only if I call SetClientSite(this) -Or-
IProfferService.ProfferService() on XP

Proffer Service works -not- on Win2003 Server :-(
actxprxy.dll exists but I do not get the interface

public class AxWebBrowser : System.Windows.Forms.AxHost,
   COM.IServiceProvider,
   COM.IHttpSecurity
{

static Guid IID_IHttpSecurity = new
Guid("79eac9d7-bafa-11ce-8c82-00aa004ba90b");

// IServiceProvider
   public int QueryService(ref System.Guid guidService, ref System.Guid
guidIID, out IntPtr ppvObject)
   {
     if (guidIID.Equals(IID_IHttpSecurity))
     {
       ppvObject = Marshal.GetComInterfaceForObject(this,
typeof(IHttpSecurity));
       return 0 /*S_OK*/;
     }
     ppvObject = IntPtr.Zero;
     return unchecked( (int) 0x800C0011);
   }

// IHttpSecurity
   public int OnSecurityProblem(int dwProblem)
   {
      [...]
   }

Guid IID_IProfferService = new Guid("cb728b20-f786-11ce-92ad-00aa00a74cd0");
   Guid SID_SProfferService = new
Guid("cb728b20-f786-11ce-92ad-00aa00a74cd0");
   IProfferService _profferService = null;
   int _cookieIHttpSecurity = 0;

   protected override void CreateSink()
   {
     try
     {
       COM.IServiceProvider sp = this.ocx as COM.IServiceProvider;

       if (sp is IProfferService)
       {
         // only XP has it
         IntPtr ipOps;
         IProfferService ps = sp as IProfferService;
         sp.QueryService(ref SID_SProfferService, ref IID_IProfferService,
out ipOps);
         object ops;
         ops = Marshal.GetObjectForIUnknown(ipOps);
         _profferService = ops as COM.IProfferService;
         _profferService.ProfferService(ref IID_IHttpSecurity, this, ref
_cookieIHttpSecurity);
       }
         
       if (0==_cookieIHttpSecurity)
       {
         IOleObject oc = this.ocx as IOleObject;
         oc.SetClientSite(this);
       }

       this.eventMulticaster = new AxWebBrowserEventMulticaster(this);
       this.cookie = new
System.Windows.Forms.AxHost.ConnectionPointCookie(this.ocx,
this.eventMulticaster, typeof(SHDocVw.DWebBrowserEvents2));
     }
     catch (System.Exception e)
     {
        Trace.WriteLine("AxSHDocVw " + e.Message);
        Trace.WriteLine(e.StackTrace);
     }
   }
     
   protected override void DetachSink()
   {
     try
     {
       this.cookie.Disconnect();
       
       if (0!=_cookieIHttpSecurity)
       {
         _profferService.RevokeService(_cookieIHttpSecurity);
         _cookieIHttpSecurity = 0;
       }
       else
       {
         IOleObject oc = this.ocx as IOleObject;
         oc.SetClientSite(null);
       }
     }
     catch (System.Exception e)
     {
         Trace.WriteLine("AxSHDocVw " + e.Message);
         Trace.WriteLine(e.StackTrace);
       }
     }
   }

Bug:
One instance of the form which includes the webbrowser control runs without
a problem. After destroying it and create a new one InitializeComponent()
-EndInit() throws an exception

"Windowless ActiveX controls are not supported."

public class BrowserForm : System.Windows.Forms.Form
{
[...]

InitializeComponent()
{
...
((System.ComponentModel.ISupportInitialize)(this.axWebBrowser)).EndInit();
...
}
}

Stack Trace:
at System.Windows.Forms.AxHost.InPlaceActivate()
at System.Windows.Forms.AxHost.TransitionUpTo(Int32 state)
at System.Windows.Forms.AxHost.CreateHandle()
at AxSHDocVw.AxWebBrowser.CreateHandle()

at System.Windows.Forms.Control.CreateControl(Boolean fIgnoreVisible)
at System.Windows.Forms.AxHost.EndInit()
at de.fun.GlobalAsax.Browsing.BrowserForm.InitializeComponent()

What i found out:
* If i do not use SetClientSite() it works  - but i do not  get
IServiceProvider-QueryService() calls
* the .Net Versions are identical (the underlying AxHost class in
System.Windows.Forms.dll 1.1.4322.2032 )
* it does not make a difference if I dispose the webbrowser control in the
form or release the interfaces
* the problem is the IE Version 6.0.3790.0 on Win2003 Server

Any ideas to solve the problem?
Is there an other way to get  calls from the IHttpSecurity Interface?
How I can use IProfferService onto Win2003 Server?

Any help will be greatly appreciated.
