Start with Chapter 8 website?

detnyre · May 15th, 2013, 01:50 PM

Wanting to start fresh with the source from Chapter 8.

I created a new website, and then did a File, Add, Existing Web Site and selected: C:\BegASPNET\Source\Chapter 08.

Then I preview (control-F5) default.aspx and it gives me:

Description: An error occurred during the parsing of a resource required to service this request. Please review the following specific parse error details and modify your source file appropriately.

Parser Error Message: The file '/Chapter 09/Site/Controls/Banner.ascx' does not exist.

----
is there a better way to get a fresh start with the chapter 8 website?

Hi there,

Did you add files from the existing website? Or did you open the web site? Your description seems to suggest you added files to an existing site rather than opening the entire site.

To open the site correctly, choose File | Open Existing Web Site and then browse to the folder. The introduction of the book, before Chapter 1, has the full details.

Cheers,

Imar

Thanks!
Was able to open and preview chapters 1 through 5.
Having problem previewing chapters 6 and greater.

I'm using Microsoft Visual Studio Express 2012.

When I open Chapter 6 by doing a File, Open Web site, and then preview default.aspx, it tells me:

================================================== ======
Server Error in '/Chapter 06' Application.

Checked the solution explorer and see the App_Themes folder with the Monochrome and DarkGrey folders in it.

Not sure what to do to fix this.....

Hi there,

It sounds like you've been following along with your own code and then used DarkGray with an a as the Theme name. Now when the code tries to set a theme it does find a cookie, but it's value (DarkGray) does not match an existing theme (DarkGrey). Clearing your cookies should resolve the issue.

Hope this helps,

Thank you - clearing the cookies fixed the problem..

Understand now why it was doing that... cookie was set with value of the theme that did not exist....

Yep; and the DarkGrey versus DarkGray naming just made that harder to spot ;-)

In the .NET 4.5 version of the book and site I modified the code in the BasePage slightly to prevent errors like this from happening:

Code:

private void Page_PreInit(object sender, EventArgs e)
{
  HttpCookie preferredTheme = Request.Cookies.Get("PreferredTheme");
  if (preferredTheme != null)
  {
    string folder = Server.MapPath("~/App_Themes/" + preferredTheme.Value);
    if (System.IO.Directory.Exists(folder))
    {
      Page.Theme = preferredTheme.Value;
    }
  }
}

This code uses Directory.Exists to first check if the Theme folder exists on disk before it tries to set the theme.

Hope this helps,

Imar

Added the updated code, just in case I go back to the version with the different spelling of the theme.

Thank you...
