Chapter 6

Tijuana · July 27th, 2012, 03:12 PM

Hi I get error message that says that 1stpreferredTheme is not a valid identifier when I actually followed what the book told me to do. It is on page 223 224. This is driving me crazy because I cant go foward to the next chapter until this is fixed, and the semester is almst over.'
Here is what my code looks like. Since I did this code i have several errors
Partial Class FirstPreferredTheme
Inherits System.Web.UI.MasterPage

Protected Sub DropDownList1_SelectedIndexChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles 1stPreferredTheme.SelectedIndexChanged
Dim preferredTheme As HttpCookie = New HttpCookie("PreferredTheme")
preferredTheme.Expires = DateTime.Now.AddMonths(3)
preferredTheme.Value = 1stPreferredTheme.SelectedValue
Response.Cookies.Add(preferredTheme)
Response.Redirect(Request.Url.ToString())
End Sub

Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
If Not Page.IsPostBack Then
Dim selectedTheme As String = Page.Theme
Dim preferredTheme As HttpCookie = Request.Cookies.Get("PreferredTheme")
If preferredTheme IsNot Nothing Then
selectedTheme = preferredTheme.Value
End If
If 1stPreferredTheme.Items.FindByValue(selectedTheme) IsNot Nothing Then
1stPreferredTheme.Items.FindByValue(selectedTheme) .Selected = True
End If
End If
End Sub
End Class

Hi there,

It's not 1stPreferredTheme as in first but lstPreferredTheme as in list. In other words, the first character needs to be a lower case L, not the number 1.

Hope this helps,

Hi there,

Not sure I understand what you mean with "it is greyed out in the file extension". Can you describe the problem in more detail?

I have to create a skin file and when I go to tools options and click file extension in the text editor catagory, I am unable to type skin and click add button(that is what is greyed out) I am asumming thats because I cant add create skin file. It is on the bottome of page 229 in chapter 6

That's odd. Have you tried restarting Visual Studio?

Note: that part is optional. Associating the skin file with the UC editor gives you IntelliSense when editing Skins. However, you can safely skip that step and just manually create the Skin files, or create the code in a User Control or Page and then copy and paste it in the Skin file. If you do that, don't forget to remove the ID attribute.

Cheers,

Yes I have restarted, but in the book on page 230 when it asked me to select skin that is not there..

I think there's some confusion about what you should do.

1. Page 229 enables you to link the .skin extension to the User Control editor. This is an optional exercise and is only used to get IntelliSense in the Skin files which is not a requirement, Is it there where the button is disabled?

2. The exercise on page 230 shows you how to create a Skin file using the Add New Item dialog. You have to rigth-click the Monochrome folder or the Skin file won't show up. Is is there where you can't find the item and click Add?

That's exactly what I am doing clicking on the monochrome folder add new item, and where it tells me to select skin file type its not there. I dont see that the only thing that shows is mybasepage. I am following what is says on 230

That's really odd. Can you upload a full screenshot somewhere showing your copy of Visual Studio with the Solution Explorer visible and the Add New Item dialog on top of it?
