Chaper 8 enum Direction

VistaFTW · April 3rd, 2009, 05:21 PM

Code:

 switch (DisplayDirection)
            {
                case Direction.Horizontal:
                    pnlHorizontal.Visible = true;
                    break;
                case Direction.Vertical:
                    pnlVertical.Visible = true;
                    break;
            }
        }
        public Direction DisplayDirection { get; set; }

I can't get this to work. It says the name Direction does not exist in the current context. I have no idea what to do.

Hi there,

Did you put the Direction enum on the App_Code folder? Can you post the code for the enum?

Code:

public enum Direction
{
    Horizontal,
    Vertical
}

The code is in the App_code folder. I've done everything exactly as written in the book. The only difference is when I started I didn't realize but I selected Web Application instead of Website. I don't know if that would make a difference.

Yes, that makes a *huge* difference. App_Code is not supported in Web Application Projects, only in Web Site Projects.

Search thos forum for posts by member4953 (http://p2p.wrox.com/members/member4953.html) to see the kind of things he ran into when using a WAP instead of a Web Site. It's doable, but requires some work.....

Thanks for your help. I am really learning a lot from this book.

You're welcome.... Hope you're having fun with it while learning... ;-)

If I were you, I'd switch to a Web Site Project. You can download the source from the Wrox site and get the version from the previous chapter. That way, you'll find it easier to follow along with the book. The lack of support for App_Code is one thing (and can easily be fixed by naming the folder something like Classes or CodeFiles), but in later chapters other things won't work either (like ASP.NET Profile which is not so easy to fix).

Cheers,

Imar

To VistaFTW,

I was using a Web Application Project. I ran into the same problem. I fixed it by not using an App_Code folder, but calling that folder Classes. I then had to make sure that the C# using statement was in the file wherein the enum was going to be used. It did work, but was kind of a pain.

Ultimately I switched to a web site project, as Imar suggests, and just ended a chapter, took the book code for that chapter and launched into the next with no problem, now using the web site project.

I just copied the source code from chapter 7 into a web site project so that I can start chapter with the website. Thanks for your tip about how to get it to work in a web app.
