I have an error - can you help me resolve it?

Error 1 Type 'Direction' is not defined. c:\BegASPNET\Site\Controls\Banner.ascx.vb 5 39 c:\BegASPNET\Site\

Code:

Partial Class Controls_Banner
  Inherits System.Web.UI.UserControl

  Public Property DisplayDirection As Direction

  Public Property NavigateUrl() As String
    Get
      Dim _navigateUrl As Object = ViewState("NavigateUrl")
      If _navigateUrl IsNot Nothing Then
        Return CType(_navigateUrl, String)
      Else
        Return "http://p2p.wrox.com"  ' Return a default value
      End If
    End Get
    Set(ByVal Value As String)
      ViewState("NavigateUrl") = Value
    End Set
  End Property

  Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
    HorizontalPanel.Visible = False
    VerticalPanel.Visible = False
    Select Case DisplayDirection
      Case Direction.Horizontal
        HorizontalPanel.Visible = True
        HorizontalLink.HRef = NavigateUrl
      Case Direction.Vertical
        VerticalPanel.Visible = True
        VerticalLink.HRef = NavigateUrl
    End Select
  End Sub
End Class

Hi there,

Did you define the Direction enum in the App_Code folder? And then saved all files?

Imar,

I copied the two files under App_Code folder from your source documents to replace mine. I then followed the instructions for the first Try It Out in Chapter 8. I have re-read this area and I don't see any instructions to change the App_Code area.

Not sure what you mean exactly. You need to create the Direction enum in the App_Code folder directly. Did you do that? What's the name of the file and what code does it contain?

DId you save and close all open files? Or try to restart VWD? Sometimes VWD doesn't pick up the changes in App_Code...

Cheers,

Imar

That did the trick! The solution you provided solves my problem. My other question is How would I have known to do this? I assume there is a place in the book that asked me to create that code, but I cannot find it. I'm only curious, since getting past this error was the important issue.

This message is sent because I forgot to rate the answer I received - excellent as usual!

For the enum code / instructions take a look at the exercise on page 284 You create the file in step 1 and add the code in step 2.

In step 8 you find instructions about using and closing all files if IntelliSense doesn't recognize the enum.

Cheers,

Imar
