Something to do with the default connection for the aspnetdb database not being there so it need something in the form of this adding to the web.config file.
Anybody know what the publickeytoken is and what it should be?

Posts 2 		I tried the shopping cart of CH18 and it worked. But now I come back to it I get the following error
when it is trying to creat items in the cart. What has gone wrong with my system to stop the cart working?

Yup, a web.config is pretty well a necessity.

Posts 170 		Hi!

Sorry you're having problems.

I'm surprised that you can get any ASP.NET 3.5 stuff to work in Visual Studio 2005. Could you try working with free Visual Web Developer 2008 Express version? (http://www.microsoft.com/express/Web/)

Also you could compare the contents of the working and non-working web.config file. There might be a reference in the one for the sample code that you need.

Let me know how you make out?

Posts 2 		I have been trying to update myself to C# while also picking up ASP.Net 3.5, which seems to be a losing battle. I have a degree in C++ so some of that is coming in handy, but I have hit a brick wall with Chapter 5's Drop Down Lists.

When I have tried your code posted on this site for C#, if I run it in your file provided, it works fine, however if I wanted to run it in my file I've created, I come up with issues with the "Cast" line:
clrs.AddRange(System.Enum.GetValues
(typeof(System.Drawing.KnownColor)).Cast<System.Drawing.KnownColor>());

Which tells me it doesn't understand "Cast"

If I just copy/paste your code from your page into a new page, I instead get an issue with the system.linq namespace, stating that it doesn't exist:

Error 1 The type or namespace name 'Linq' does not exist in the namespace 'System' (are you missing an assembly reference?) C:\Documents and Settings\Drowning Rabbit\My Documents\Visual Studio 2005\WebSites\WebSite6\Default.aspx 3

I'm at a loss at where to look for an answer in Visual Studio at this point (I own a copy of VS 2005, and is what I've been using), as when I load your code, everything works, but just a simple copy/paste and I get that issue.



E: Now I'm running into the exact same problem with Page 72, Getting Multiple Choices from a ListBox. Something is odd with the line:
<%@Import Namespace="System.Linq" %>


Again, everything works fine when I use the code provided on the site, yet when I try and run it myself in a different file, it blows up.

topic: Drop Down List Control

Posts 1 		This is a great book!

I have a question regarding drop down lists. I would like a drop down list to display the text: "-Select-" initially instead of the first value of the data it is bound to. How do I do that? I'm a newbie. Is there any way to do this by using the control tasks items instead of goin directly to the source code? For example, I would like to display it in the example on p.89. Instead of displaying the first Country, I want it to say "-Select-".

Thanks!

Hi again,

The Button ID does not work unless you add onclick="Button1_Click" figured that out when I downloaded your code. What I don't get is, when I look into the properties there is no onclick only a onclientclick which doesn't work like the onclick. So where does the onclick come from?


I'm surprised that you're not seeing the OnClick event. It appears with a lightning bolt icon in my IDE. OnClientClick appears next to it in Intellisense.

If you're using the Properties page (F4) to get at the event, you might need to move into Design view and then click the lightning bolt icon to get the list of server-side events.

Does that help at all?

topic: Using JavaScript and images for rollovers

Ken Cox
Posts 170 		The idea is to have a slightly different version of the image so that there's a visible indication that the mouse has passed over and back out.

It's fairly common to have an image button that glows (or otherwise changes appearance) on a mouse action. It's a simple little demo, similar to the one you see here:

http://www.designplace.org/static/rollover_button_example.html

It's not meant to be deep or anything so I'd say you're not missing anything. <grin>

Posts 5 		Hi Ken,

The exercise you propose on rollovers using your picture has got me confused, namely the pictures are a different shade to begin with. If I use any other two pics of the same shade the trick does not work. So what is the point if I have to photoshop a copy of the picture I wan to to create a rollover effect for? What am I missing here?

Thanks,

Posts 170 		Hi!

Sorry you're having difficulty.

I'm not sure what the problem could be, but could you try downloading and installing the source code for the Chapter 9 to see if that database works on your machine?

Make sure your project has a web.config file in it, 'cause that's where the connection info is stored. If you send me the web.config, I might be able to see what's causing the failure.

Thanks,

Ken

Posts 5 		Hi Ken,

Great book! Congrats! Now for the problem...

When I click next after configuring the data source in the AccessDataSource control I get the following error;

"Database schema could not be retrieved for this connection. Please make sure the connection settings are correct and that the database is online. Cannot open database"

Likewise if I double click the db in Solution Explorer I get "Cannot Open Database."

I am running XP SP3, Access 2007, and VS 2008 Team Edition.

Can you help?

PS

I also tried converting the db to access 2007 but that did not work either, same error.

Thanks

topic: pg 81 Advanced SQL Generation Option greyed out

Posts 2 		Problem solved, shame on me .

I've skipped the not so unimportant point 6 on pg 81:
"CHoose the Customers table"

So I've left the selection at the 1st table on top, and it seems that it was empty.

Now the Advanced box isn't greyed out anymore, and everything works smoothly.

Sorry for the disturbance.

Posts 2 		Dear Ken,
at first thanks for your great book, it really eases my way into the last release of the .Net World.

My problem:
-) I downloaded the Sample Databases from MS, no problem there.
-) I attach the DB-File northwind.mdf
-) I draw a SQL Data Source into the form
-) But when I click on the advanced button, both options are greyed out.


Do I have to enable wrte access to the database somehow?

The test query works fine, but I can just select, not do any changes to the table.

TIA, Martin

Posts 170 		Hi Christian,

I wasn't aware of the Portuguese version until a reader contacted me. It looks like the publisher did a bad job on transcribing the code snippets. You've found some of the typos and there are obviously more.

If you go to this page and enter 68 (as the page number) and click GO, you'll see the correct source code:

http://kencox.ca/sourcecode.aspx

You can also download the complete code for the chapter here:

http://www.kencox.ca/samplecode/195925_CH05_Code.zip

I'm sorry about the mistakes. If I had been given a chance, I'd have checked the manuscript.
