Morteza,
I am no longer able to run the browser because of the error.

You can run browser even it has errors. Please tell me error page URL. Test following(i assume you have only "ELement 'Banner' is not known element" error)tips. If one of approaches worked keep stop process an please comment.

1- Remove

and Banner1 control in masterpage and instead of that in design view drag Banner user control into master page and drop it.
2- Completely Remove( hold it outside the project) Banner user control and copy Banner control from book source code to your project.
3- Run your application in iis( do you know how?)
4- If any of above issues don't works please run your website in other PC. I think your VS 2010 has problem.

Morteza,

I think I found the problem.

I did what you said and also removed one line from AboutUs (code Behind), which is [Banner2.DisplayDirection=Direction.Vertical/] and everything is working fine. As soon as I put the line back I had the following error:
"Banner2 is not declared. It may be inaccessible due to its protection level".

So this is the problem and don't know how to fix it. I also don't know how to run my application in IIS. I would appreciate your help.

Thank you very much
Regards
Khalil

Running your site from IIS shouldn't be necessary.

As hinted earlier, maybe there's a problem with the control itself? Can you post its code? Or better yet, try adding my control from the book's download to the project, and then drop it on the design surface of a page. Does it work then?

Cheers,

Imar

The codeof my control is:
[<%@ Control Language="VB" AutoEventWireup="false" CodeFile="Banner.ascx.vb" Inherits="Controls_Banner" %>
<asp:Panel ID="VerticalPanel" runat="server">
<a href="http://p2p.wrox.com" target="_blank">
<asp:Image ID="Image1" runat="server" AlternateText="This is a sample banner"
ImageUrl="~/Controls/Images/Banner120x240.gif" />
</a>
</asp:Panel>

<asp:Panel ID="HorizontalPanel" runat="server">
<a href="http://p2p.wrox.com" target="_blank">
<asp:Image ID="Image2" runat="server" AlternateText="This is a sample banner"
ImageUrl="~/Controls/Images/Banner468x60.gif" />
</a>
</asp:Panel>/]

OK, try this:

1. Confirm you have a Web Site Project (each ASPX file should only have one Code Behind file)

2. Make sure you created the Direction Enum in the App_Code folder in a .cs or .vb code file

3. Make sure you added the property DisplayDirection to the Baner control's code behind.

4. Drag the control to a page again.

If you have trouble figuring this all out, zip up the site and send me a copy. You'll find my e-mail address in the introduction section of the book.

Cheers,

Thanks for the source. The code looks fine to me for the most part (after I figured out which of the many folders you sent me contained your site).

A few remarks:

1. The App_Code folder contains your About and Reviews folder which is not OK as you can't request them and they may cause other issues. This files and folders should really be in the site's root.

2. How do you open the web site and what do you see in the browser? Here's what you should do and what works for me:

a) Start VWD and choose File | Open Web Site. Browse to the folder C:\BegASPNET\PlanetWrox and click OK. Make sure you don't choose the parent folder C:\BegASPNET

b) Open the Project's Properties Grid (select the project in the Solution Explorer and hit F4) and set the Virtual Path property to /

c) Hit F5. The homepage should appear appear with the banner in Horizontal mode

d) Open the Master file and add DisplayDirection="Vertical".

e) Save and reload

If this still doesn't work, between step b and c, move the About and Reviews folders to the root of the site, and right-click the project and choose Build or Rebuild.

If it still doesn't work, I don't know what's going on. It works fine for me with the code you sent me.

Cheers,

Imar

Hi Khalil,
I think the problem is by your vs 2010 . Try testing project in another PC(with vs 2010) as i suggested in earlier .

Hi Imar,

I still have a problem with "Banner2".
The following is my code in AboutUs and its code behind:

[<Wrox:Banner ID="Banner2" runat="server" DisplayDirection="Horizontal" ></Wrox:Banner>/>]

[Partial Class About_AboutUs
Inherits BasePage

Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
If Not Page.IsPostBack Then
Banner2.NavigateUrl = "http://imar.spaanjaars.com"
End If
End Sub

End Class]

Regards
Khalil

Thank you for attending to my query.

Hi Khalil,
I am sorry, But Please pay attention to our ask for using book source code. By this we can find the problem is by VS 2010 or by Banner User control.

Is that all the code in AboutUs.aspx? If not, can you please post the full code? This may be easy to solve but not without knowing what's going on....

Cheers,

Imar
