Hello,
I'm trying to implement sample I found on page templates, so I do not have
to maintain "<html><head>.. ." on all my documents. But don't let that
confuse you, this is an inheritance problem.
Basically, I'm using VS.NET IDE for development, If I use the src="..." tag
in the @Page directive it works, but if I use codebehind="... ", I get a
runtime error that it cannot find my first class I'm inheriting. It's
almost like the assembly dll it is compiling doesn't contain the namespace
I've defined (But I have rebuilt it, even checked the timestamp to make sure
it is being updated)
The error I get from the browser when requesting default.aspx is as follows:
Parser Error Message: Could not load type 'aspdotnet.Page TemplateSetup'.
(and it highlights my @page directive line)
I originally had a C# example and changed it down to VB.NET, so I'm sure I'm
missing something simple.
Here is my source files, if it helps.
default.aspx
*************** **
<%@ Page Language="vb" AutoEventWireup ="false" Codebehind="def ault.aspx.vb"
Inherits="aspdo tnet.PageTempla teSetup" %>

Hi,
I understand that the CodeBehind= is designed to be used
by VS and not actually part of the .NET framework
However, in my BenefitsVB project to test how the SRC

I've read that in the Page Directive of an aspx page, changing the
CodeBehind attribute to Src saves you from having to compile the page before
refreshing. This is preferable in a large development environment where
rather than having each developer running a local copy of a website, they
can make changes simultaneously to a central web server without stepping on
each other's toes as far as compilation is concerned.
ANYWAY, this is fine...

I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
