"non-shared member requires an object reference" error within class

Is there a restriction referring to the Request, Response and Server properties from within a class method?

I'm trying to get a VB Class to compile that refers to Request.QueryString, but the compilation fails with the error:

BC30469: This reference to a non-shared member requires an object reference, and none is supplied

Here's an example of a method that is failing:

Line 244:	Private Sub NoFrames
Line 245:
Line 246:		Response.Write("<noframes><body><p>This page uses frames, but your browser doesn't support them.</p></body></noframes>")
Line 247:
Line 248:	End Sub

Any help appreciated,

-david

You have some basic VB learning to do!

Try this :
<Script Language="VB" runat="server">
Private Sub NoFrames

Response.Write("<noframes><body><p>This page uses frames, but your browser doesn't support them.</p></body></noframes>")

End Sub
</SCRIPT>

Notice...no compilation error, although nothing happens.

Now, add under this under that script :

<%
NoFrames
%>

And your Sub will execute...

For a more practical example, instead of the simple NoFrames call, use :

<%
If Request.QueryString("frames")="no" Then
NoFrames
Else
End If
%>

Then, if your querystring looks like this : http://server.com/FramesOrNoFrames.aspx?frames=no

If frames=no, the Sub will execute and render the <noframes> text;

If frames=anythingelse, or if frames is not in the querystring, the text will not be rendered.

To recap : if you do this :

<%
Private Sub NoFrames
Response.Write("anything")
End Sub
%>

You will always get the error you are getting now.

Procedures are compilable only if their declaration context allows it.

If you declare a Sub within a script block, it will compile.

<Script Language="VB" runat="server">
Sub ThisWillCompileOK
End Sub
</SCRIPT>

If you declare a Sub within <% ... %> delimiters, it will not compile.

<%
Sub NoWayThisWillCompile
End Sub
%>

thanks, but i already understood that VB stuff! I think you might have been mislead by my code sample. My problem is that the subroutine is a method of a Class. I have no problem calling a subroutine in other cases!

Here's another example:

<%@ language="vb" %>
<SCRIPT LANGUAGE="vbscript" RUNAT=Server>

Class Fred
'
' Display message for browsers that don't support frames
Private Sub NoFrames

Response.Write("<noframes><body><p>This page uses frames, but your browser doesn't support them.</p></body></noframes>")

End Sub

End Class

</SCRIPT>

Compilation dies on the Response.Write still.

any ideas now?
