Could someone please tell me the difference between CodeFile= and CodeBehind= in an .ascx file? VB puts a CodeFile in by default and I noticed that some of the controls in the core, like admin/skins/Login.ascx use it. However, when I try to use it in my ascx skin file I get an error message:

Could Not Load Skin: /Portals/_default//skins/test_skin1/skinwebusercontrol.ascx Error: The file '/DotNetNuke/admin/Skins/skin.vb' does not exist.

When I change my CodeFile= to CodeBehind= everything works just fine.

What's the difference? Thx.

The "CodeBehind" is a legacy attribute from ASP 1.1. "CodeFile" replaced it in ASP 2.0.

This is probably your culprit code: <%@ Control language="vb" CodeBehind="~/admin/Skins/skin.vb" AutoEventWireup="false" Explicit="True" Inherits="DotNetNuke.UI.Skins.Skin" %>

While I don't know the exact reason, I suspect it has to do with the way the "skin.vb" module is coded. "CodeFile" should point to a module that resolves the "DotNetNuke.UI.Skins.Skin" partial class.  The "skin.vb" module is probably not coded in a ASP 2.0 way that resolves that class.

That's not really an answer, but I hope it helps.

Thanks for that historical reference clarification. I've been stuck in a major Classic ASP project for years and am now jumping into ASP.NET deeply for the first time. Yes, the line that causes the error is:

<%

@ Control Language="VB" AutoEventWireup="false" CodeFile="~/admin/Skins/skin.vb" Inherits="DotNetNuke.UI.Skins.Skin" %>

So, I gather from what you say that if they recoded skin.vb for ASP 2.0 this problem would go away. In the Install package, there is no actual module in admin/Skins called skin.vb; it exists only in the source package and is the only .vb module there that is not an .ascx.vb file. I had a quick look at the source for skin.vb but don't yet know enough about the differences between ASP 1.1 and ASP 2.0 coding to see evidence of what you are talking about. However, it does sound plausible.

If that is the problem, is that not a bug? Should we report it?
