Could not access 'CDO.Message' object

RE: Could not access 'CDO.Message' object

Hi Thys,

Have you ever sent e-mail successfully with System.Web.Mail class before
you installed the Office XP?
Can you tell me if your smtp server used to send email need client
authentication, which may caused the problem, Since you can not set the
client authentication with the System.Web.Mail class?

Re: Could not access 'CDO.Message' object

Hi,

I added a reference to Microsoft CDO for Exchange library in my project, and
changed the code to use CDO.MessageClas s (and had to change a few
properties, including the Configuration.F ields). This works, although there
are no authentication properties set. I'm using my local SMTP server, and it
worked using the code below (the code is run in a web server control):

CDO.MessageClas s mail = new CDO.MessageClas s();
mail.Subject = "Record change";
mail.From = "test@test.co.z a)";
mail.HTMLBody = "<HTML><Body><F ont Face=\"Arial\" Size=\"2\">";
mail.HTMLBody += "A change has been made to a record in the table " +
strTable + " by " + this.Page.Sessi on["UserName"] + ". ";
string sURL = this.Page.Reque st.Url.ToString ();
mail.HTMLBody += "To view the change(s), visit the website at <A href=\""
+ sURL + "\">" + sURL + "</a>.";
mail.HTMLBody += "</Body></HTML>";
mail.BCC = "test@test.co.z a";
mail.To = recip.Substring (0, recip.Length - 1); //recip is a string
containing all the recipients
mail.Configurat ion.Fields["http://schemas.microso ft.com/cdo/configuration/se
ndusing"].Value = 2;
mail.Configurat ion.Fields["http://schemas.microso ft.com/cdo/configuration/sm
tpserverport"].Value = 25;
if(this.Page.Ap plication["MailServer "] != null)
{

mail.Configurat ion.Fields["http://schemas.microso ft.com/cdo/configuration/sm
tpserver"].Value = this.Page.Appli cation["MailServer "].ToString();
}
mail.Configurat ion.Fields.Upda te();
mail.Send();

I haven't tried sending mail before installing Office XP, the only reason I
thought it might be this, is because I found an article on MS website saying
that Office XP replaces the CDO library, and replaces the reference to it in
the registry. Any further ideas?

PS - I should warn everyone - don't post with your real e-mail address -
since posting my original message, I've been spammed with these stupid
"Microsoft Update" virus e-mails - I've received about 30 in the last 18
hours.... MS should find these people and sue them for identity theft, etc,
etc, etc....

Re: Could not access 'CDO.Message' object - The answer

For those of you who were wondering about this, I found the solution. It's a
permissions problem. I added the following code at the top of my class, and
it worked!

using System.Security .Permissions;
[assembly:Permis sionSetAttribut e(SecurityActio n.RequestMinimu m, Name =
"LocalIntranet" )]
