non-shared member errors

[tshad]

I have a program I am trying to compile into a dll and am getting a bunch
of: the following errors:

error BC30469: Reference to a non-shared member requires an object
reference.

At first, I thought it was because I had the sub set as shared, but I get
the same error if it take the Shared out.

What is causing these errors?

I assume that the class Emails inherits from Page, though that's not shown
here. The trouble is that you refer to the Request object inside a shared
method. A shared method does not have access to instance-specific variables
like Request. The Request object is unique for each instance of a Page
object. So a shared method can't refer to it. It can only refer to objects
that are shared across all instances of a given class. So if your class had
declared a class-level shared variable, then your shared method could refer
to it.

But if I take the "Shared" of the Sub line, it gives me the same errors?

If I change:

Shared sub sendTheEmail( )

to

sub sendTheEmail( )

It is the same.

Is there somewhere I can look to find out the difference between shared and
unshared for my asp.net pages to find out the best way to build these?

Thanks,
