Hi u all!!!

I have a website, dedicated to beauty products for women, ok? Sometime ago a friend of mine told me "hey! why don´t you send that info through MSN?". I liked that, so I downloaded an autoresponder code from here:

http://nayyeri.net/blog/auto-responder-add-in-for-windows-live-messenger/

So I simply added this routine to get search results from my site:

public string getSiteSearchResults()
        {   string reader = "";
            string search = "[the received message text goes here]";
            string url = "[the URL of my website search page]?query="+ search;
            try            
            {
                WebPermission pWeb = new WebPermission(NetworkAccess.Connect, url);
                SecurityPermission pSec = new SecurityPermission(SecurityPermissionFlag.AllFlags);
                PermissionSet set = new PermissionSet(PermissionState.None);
                set.AddPermission(pWeb);
                set.AddPermission(pSec);
                set.Assert();
                HttpWebRequest URLReq = (HttpWebRequest)WebRequest.Create(url);                
                URLReq.Credentials = CredentialCache.DefaultCredentials;
                URLReq.AuthenticationLevel = System.Net.Security.AuthenticationLevel.None;
                URLReq.AllowAutoRedirect = true;
                URLReq.Timeout = 60000;                
                HttpWebResponse URLRes = (HttpWebResponse)URLReq.GetResponse();                
                Encoding enc = Encoding.GetEncoding(1252); 
                StreamReader sStream =   new StreamReader(URLRes.GetResponseStream(), enc);            
                reader = sStream.ReadToEnd();                
            }
            catch (Exception ex)
            {
                reader = ex.Message ;
            }                       
            return (reader);                
        } 

So when somebody asks for some product, the addin (working on one of my pcs) do a search on my site, get the results and send ´em in response as plain text.

Well, instead of that, all I get is this:

"Request for the permission of type 'System.Security.Permissions.SecurityPermission, mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed."

I read about gacutil, regasm, caspol, trust zones, trusted assembly, security zones...... but don´t have a clue where to start to get rid of this thing, really.

Any help is truly appreciated

Why aren't you using a WebClient?

var m = new WebClient();
var result = m.DownloadString("http://www.google.com/search?hl=en&q=test&aq=f&oq=");
MessageBox.Show(result);

I'm only asking this because it looks like you are just wanting to submit a basic GET url and receive the result in a string.

I have never tried that before.... I'll give it a try and let you know... But, what's the difference between the WebClient approach and the one I used??

GLAD you wrote!!!
Ariel

well all the stuff you were doing is actually done inside the WebClient - plus it handles all protocols and securities for basic page browsing. - it's like one step down from the WebBrowser object that actually renders the pages and runs scripts and all that.

At least that's my understanding of it. :)

No luck at all... same error using WebClient object,
dunno ... tks anyway...
Ariel

Is there some kind of firewall or protection system that may allow your web browser to access the internet, but not other applications on the machine you are running from?

Vista I think by default is set up to do this.

Or - are you running through a proxy? You might need to set up the proxy on the WebClient.

Using the web client should be able to assure you there is nothing wrong with your code as far as accessing a web page, so something externally must be blocking or not allowing your application access to the outside world.

Also - do you have to log into your site? Does it need a cookie or any kind of authentication in order to access the page you are accessing?

dammit - this thing keeps double-posting
