something Weird has happened

Hello Imar:

I can no longer preview your project that I built!
I had finished all but chapters 17 & 18 and will be finishing them up soon.

But I've been working on my own website and am using some ideas from another project (beerhouse).

I just tried to open up the Planet Wrox project now, and I get the following error:
========

Server Error in '/' Application.

Theme 'PlainHtmlYellow' cannot be found in the application or global theme directories.

==========

I had been trying to figure out why the dropdown list wouldn't show up when I switched from the template monster theme to the plain yellow theme in my own project. I had been working in my own web, and then when I needed to refer to something, I always shut my web down before opening the beerhouse project and shut it down before opening mine. This time, I shut down that Beerhouse project and opened yours because the drop down list worked fine in it. But when I tried to view my planet wrox web in the browser I got that weird message.

So I rebooted. Then after rebooting, closed all the open pages and rebuilt the project. Tried to open it again. But still this message persists. It doesn't refer to any page in the project. Is it something in the main Net files I need to do something with?

What do I do??

Hi Rachel,

Are both projects located in their own folder? They should be, or they would interfere with each other. If you do have separate folders, you can easily have them open together. (I often have many web site projects open in different instances of Visual Studio).

Anyway, you probably need to search for PlainHtmlYellow. I am not familiar with the Beerhouse so I don't know if that's your theme, or the Beerhouse's theme. With your project open in Visual Studio, press Ctrl+Shift+F (find in files) and search the entire site for PlainHtmlYellow. There's a fair chance it's in web.config.

If that doesn't help, you may need to widen your search on your computer to see where it comes from.

Cheers,

Imar

Hi Imar:

Thanks for responding. I had been careful to only have one solution open at a time for I had seen things in the past get mixed up. And I did in fact do a search for the plainyellow doing it by searching the entire solution, but nothing showed up.

I'm wondering about one thing. I couldn't get the dropdown list to show up when I switched to the plainyellow theme. So I had copied some of the code from the project I had built on your project, that creates the cookie - from page 223. I then had run the other project (my web, but using the code from beerhouse). So when I ran it, I then clicked on the plainyellow theme. I don't remember why now, but I was worried that mixing up extra code might give me problems later so I took that back out. But could I have created a cookie for plainyellow that now my planet wrox is trying to read for some reason? That error message doesn't refer to any page in that project. Could this be coming from the main .Net folder under windows like machine.config ?

EDIT:
Update:

Hi Imar:

There are a ton of references to "PlainHtmlYellow" under my C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\Temp orary ASP.NET Files\tbh_web\ *with various extensions here*
as well as under
C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\Temp orary ASP.NET Files\testWebSite\ *with various extensions here*
C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\Temp orary ASP.NET Files\myNewWeb\ *with various extensions here*

specifically, I looked under them here:

C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\Temp orary ASP.NET Files\myNewWeb\7b620315\7d763afc
C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\Temp orary ASP.NET Files\myNewWeb\7b620315\7d763afc

Can I safely delete them?

Hi Rachel,
I had a similar problem - it had to do with cookies. I used the same code from the book for saving the selected theme in a cookie for my personal site - and as such, used the same var name for it (PreferredTheme). When you run VWD and use its built in server, the host is localhost, so the cookie is always cookie:yourusername@localhost - regardless of which site you're actually viewing at the time. The workaround for me (other than wiping out the cookie each time) was to make sure no cookie variable names overlapped between sites.

Good Luck,
Mrs. CB Spira

Hi:
Thanks. How do I get rid of the cookie that is there now?

cbspira · January 8th, 2009, 02:33 PM

In Windows XP cookies are stored in:

Code:

C:\Documents and Settings\yourusername\Local Settings\Temporary Internet Files

look for the file Cookie:yourusername@localhost

It's a text file so it will open in notepad if you want to verify that this is indeed the source of your problem...

you should be able to just delete it (or rename it if you want to preserve the contents)

I don't know where Vista stores the cookie files. If you want to get drastic you can use IE's Tools, Internet Options, General Tab, Delete... to delete all temporary files - but that's overkill, IMHO

Rachel · January 8th, 2009, 03:13 PM

OH THANKS SO MUCH!

That was really a tangled web trying to figure that out. And it was all just a cookie! I deleted that localhost cookie, and now its working fine.

edit: I see I need to change that variable name for the preferred theme if I want to store a cookie again.

Rachel

cbspira · January 8th, 2009, 04:11 PM

You're welcome

Yup, you have to change the variable name if you want to still use the cookie - one of the pitfalls in reusing code...
Note that this probably would not be an issue in production server since the 2 sites would most likely not live at the same domain name...

I put a comment in CAPITAL letters above that snippet of code in my planet Wrox web so I would not make that mistake again!

Great; glad it's all working again now....
