Send Mail with a Proxy Server That Is Configured Manually

1. Start Microsoft Visual Studio .NET.
2. On the File menu, point to New, and then click Project.
3. Click Visual C# Projects under Project Types, and then click Console Application under Templates. By default, Class1.cs is created.
4. Add a reference to the Microsoft CDO for Windows 2000 Library and the Microsoft ActiveX Data Objects 2.x Library. To do this, follow these steps:
   1. On the Project menu, click Add Reference.
   2. Click the COM tab.
   3. Click Microsoft CDO for Windows 2000 Library, and then click Select.
   4. Click Microsoft ActiveX Data Objects 2.x Library, and then click Select.
   5. Click OK. If you are prompted to generate wrappers for the libraries that you selected, click Yes.
5. In the Code window, replace the default code with the following code:

   namespace CdoSys
   {
       using System;
       class Class1
       {
           static void Main(string[] args)
           {
               try 
               {			
               CDO.Message oMsg = new CDO.Message();
               CDO.Configuration iConfg = new CDO.Configuration();
               ADODB.Fields oFields;
               ADODB.Field oField;
   
               oFields = iConfg.Fields;
   
               // Set Proxy properties			
               oField = oFields["http://schemas.microsoft.com/cdo/configuration/urlproxyserver"];
   oField.Value = "itgproxy";
   
               oField = oFields["http://schemas.microsoft.com/cdo/configuration/proxyserverport"];
   oField.Value = 80;
   
               oField = 
   oFields["http://schemas.microsoft.com/cdo/configuration/smtpsserver"];
   oField.Value = "smarthost";			
   
               oField = 
   oFields["http://schemas.microsoft.com/cdo/configuration/smtpserverport"];
   oField.Value =25;			 
   	
               oFields.Update();
   
               oMsg.Configuration = iConfg;
   
               // Set common properties for Message
               oMsg.Subject = "Test SMTP";
               oMsg.From = "from@microsoft.com";
               oMsg.To = "to@microsoft.com";
   
               oMsg.Send();
               }
               catch (Exception e)
               {
                   Console.WriteLine("{0} Exception caught.", e);
               }
               return;
           }
       }
   }
   					

6. Modify the code where you see the TODO comments.
7. Press F5 to build and to run the application.
