WithEvents in VB 2005

Any suggestions why I get the following error: "Handles clause requires a WithEvents variable defined in the containing type or one of its base types"? It occurs on the "emlbutton" of "handles emailbutton.click." I'm a newbie so maybe this is just something simple I'm overlooking...

Public Shared Sub emlbutton_click(ByVal subject As String, ByVal messageBody As String, _
        ByVal fromAddress As String, ByVal toAddress As String, ByVal ccAddress As String) Handles emlbutton.click

"Handles" requires a corresponding declaration using the "WithEvents" keyword.  For controls added at design-time in the IDE, this is done for you and placed into a normally hidden file.  In the Project Pane, click on the "Show all files" button and then double click on the xxx.designer.vb file for your form.

You should have something like this in there:
(don't modify this file manually!)

    Friend WithEvents Button1 As System.Windows.Forms.Button

The error is telling you that it can't find the matching WithEvents declaration for "emlbutton" in the designer file (or the current class code).

So somehow your designer file has become corrupt or out of "sync" with your code, or you have a locally declared variable that needs "WithEvents" added to it.

Idle Mind,
Your are correct. I tried to to view my file in design time but VB is telling me I have errors (however, I can still view in a browser). So let's back track a little...
The error is "Cannot switch views: Validation (XHTML 1.0 Transitional): Element 'link' cannot be nested within element 'html'. " I must admit that I cheated a little in that I copied and pasted from a html view source file as that was all I had access to at the time and I need the css style sheet.  Here are the "links" that are causing the problem. I guess I don't understand why the links cannot be nested within html when the entire page is html.


<link rel="stylesheet" href="http://www.mulliganagain.com/wp-content/themes/default/style.css" type="text/css" media="screen" />
<link rel="alternate" type="application/rss+xml" title="&#8220;I&#8217;ll take my Mulligan now!&#8221; RSS Feed" href="http://www.mulliganagain.com/?feed=rss2" />
<link rel="alternate" type="application/atom+xml" title="&#8220;I&#8217;ll take my Mulligan now!&#8221; Atom Feed" href="http://www.mulliganagain.com/?feed=atom" />
<link rel="pingback" href="http://www.mulliganagain.com/xmlrpc.php" />

I'm glad we've narrowed down the problem...but unfortunately I have NO clue when it comes to web programming.  I simply focused on the core WithEvents/Handles error....   =(
