C# DLL nightmare
 
Hi u all!!!

I have a website, dedicated to beauty products for women, ok? Sometime ago a friend of mine told me "hey! why donīt you send that info through MSN?". I liked that, so I downloaded an autoresponder code from
nayyeri.net/blog/auto-responder-add-in-for-windows-live-messenger/

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

Code:

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 īem in response as plain text.

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

Code:

Code:

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 donīt have a clue where to start to get rid of this thing, really.

Any help is truly appreciated

Txs in adv
