Hi experts!

      I have two projects ...

so First project cs code like this,
===========================

using System;
using EwaoListingCommon;

namespace Cititown
{
       /// <summary>
       /// Summary description for Compose.
       /// </summary>
       public class Compose : CommonPage
                                               // SEE HERE
       {
               protected System.Web.UI.HtmlControls.HtmlInputHidden
hPostingID;

               private void Page_Load ( object sender, EventArgs e )
               {
                       bool bFileRemoved = false;
              }
      }
}

Second project code like this,
======================

using System;
using EwaoListingCommon;

namespace Cititown.myemails
{
       /// <summary>
       /// Summary description for Compose.
       /// </summary>
       public class ListingComposeGraphic : XmlPage
                                                              // SEE
HERE
       {
               protected System.Web.UI.HtmlControls.HtmlInputHidden
hAction;

               private void Page_Load ( object sender, EventArgs e )
               {
                       bool bFileRemoved = false;
                }
        }
}

If I am using like this
==================

using System;
using EwaoListingCommon;

namespace Cititown.myemails
{
       /// <summary>
       /// Summary description for Compose.
       /// </summary>
       public class ListingComposeGraphic : XmlPage  , CommonPage
                                                         // SEE HERE
       {
               protected System.Web.UI.HtmlControls.HtmlInputHidden
hPostingID;

               private void Page_Load ( object sender, EventArgs e )
               {
                       bool bFileRemoved = false;
                }
          }
}

I got error like this is not type of interface

I suspect that you are attempting multiple inheritance, which isn't
supported in C# (or .Net AFAIK); ListingComposeGraphic can inherit from one
or the other, but not both.

But! don't tell us something *like* the error message. Just copy / paste. It
will be less typing, and might actually tell us the problem!!!

Hi Sala,

C# doesn't support multiple inheritance for classes.

in the line:

>        public class ListingComposeGraphic : XmlPage  , CommonPage

you try to inherit from 2 classes. That's not posseble.

If CommonPage were an interface, this would be possible. That's why the
compiler says 'this is not type of interface'

Unless you actually go to the trouble of telling people what error you get
(exact text), and when (runtime / compile-time), I doubt many people are
going to bother trying to infer...

See other post; you're currently attempting to use multiple inheritance. I
can't answer tell you the correct way of accessing it unless you can clarify
what you are trying to do... it really isn't very clear, sorry.
