I am a DNN Newbie but very experienced (i.e. old) software development geek.

DotNetNuke 4.3.5

Visual Studio 2005 - I have the full version and not the Express Version

My development machine is Windows XP Home

Module works fine when logged in as host or admin.  Generates an error message when not logged in.

I simply created a new module and renamed the directories and tried to install it per default instructions.  The exception I get is:

I've searched the boards and the web and it seems that module development has changed quite dramatically recently and I haven't been able to find a problem quite like mine.

Any Suggestions?

You need to explicitly turn off caching for your module.  Both in the module definition and the instance of the module on the page.

Here is the method.  This is strictly boiler plate from the Starter Kit.  I didn't write a line of this....

I will try the caching and see if that works.

Thanks,

Keith

 

Protected Sub lstContent_ItemDataBound(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.DataListItemEventArgs) Handles lstContent.ItemDataBound

Dim strContent As String = strTemplate

Dim strValue As String

' add content to template

Dim objProperties As ArrayList = Common.Utilities.CBO.GetPropertyInfo(GetType(JATFirstInfo))

Dim intProperty As Integer

Dim objPropertyInfo As PropertyInfo

For intProperty = 0 To objProperties.Count - 1

objPropertyInfo = CType(objProperties(intProperty), PropertyInfo)

If strContent.IndexOf("[" & objPropertyInfo.Name.ToUpper & "]") <> -1 Then

strValue = Server.HtmlDecode(DataBinder.Eval(e.Item.DataItem, objPropertyInfo.Name).ToString())

strContent = strContent.Replace("[" & objPropertyInfo.Name.ToUpper & "]", strValue)

End If

Next intProperty

' assign the content

Dim lblContent As Label = CType(e.Item.FindControl("lblContent"), Label)

lblContent.Text = strContent

End Sub

Turning of Caching worked!  Thanks,

Now the question is why?
