Hello,

All code has worked fine up to this point and this book has been a good "Quick immersion" into ASP.net.

I don't mean to discourage anyone from the book, if someone can confirm this chapters code works I will assume it is just my system configuration.

I am not sure the code for Chapter 19a is functional. I have attempted it 4 times, followed along with the video and even copied from the Book solutions the DataLayer folder and Lession19a folder and I still receive this error.

C:\Documents and Settings\Dad\My Documents\ASPNETTrainer\Lesson19a\Lesson19a\Catego ry.aspx.cs(14,13): error CS0246: The type or namespace name 'DataLayer' could not be found (are you missing a using directive or an assembly reference?)

This appears twice in the output.

I assumed if I copied over the folders from the web site (Datalayer and Lession19a) I would have exactly what you do in the video but is there something else I should try?

I noticed on page 304 #18 you add "if (!Page.IsPostBack) and the DataLayer line of code we add to the Page_Load on page 303 #13 is missing but I receive errors if I delete the line.

All code has worked fine up to this point.

Thank

Hello,

The DataLayer namespace is in the DataLayer.dll. Have you tried using the DataLayer.dll that is in the solution? Please see Step 8 of the Step-by-Step guide for more information.

Ok, I was attempting to save all the work in the My Documents and no matter how careful I was to change all the paths the code never worked. I even updated the connection string. When I redid Chapter 18 and Chapter 19 into C:\ASPNETTrainer\ everything works perfect. Perhaps the code did not like the blank spaces in the path when using "My Documents".

At least I can continue on to the rest of book.

Great first immersion into ASP.net. Definitely a good purchase.

I'm having the same problem with the code in 19a as the other user. I am referencing the correct DataLayer.dll, but the code still won't work.

Thanks.

The ConnectionString.txt that is provided makes a couple of assumptions. First is assumes that you are using SQLExpress and second that SQL Express is running. If you are using a named instance for SQL Server, please update the ConnectionString.txt information with the correct information and verify that SQL Server is running.
