How do you add your own methods to an MFC/ATL ActiveX Control project Either I get compiling errors or the ASP page claims that the "object doesn't support the property or method". I've used this script (see below) for other ActiveX controls I've worked with and it has worked, and still works for them. I want to use the code automatically generated when adding a new MFC ActiveX Control project because I want to be able to write an ActiveX component for a Windows CE device. And there is a project type for VC++ called MFC Smart Device ActiveX Control. When I deploy the MFC Smart Device ActiveX Control to the Windows CE device, register it and go to the page with the script below, I get an error on the second line ( str=obj.Question() ). If I comment out all VBScript but the "CreateObject"-line I get no errors, and the ASP page works.
<%
Set obj=Server.CreateObject("AXTEST.AxTestCtrl.1")
str=obj.Question() ' Here is where the error occurs
%>
<html>
<title>
Test ActiveX Server Component
</title>
<body>
<span style="{font-family:Arial}">
<%=str%>
</span>
</body>
</html>
P.S. For WinCE Set obj=CreateObject("AXTEST.AxTestCtrl.1") D.S.

I've never used the for smart device template and it might not be the same, but this might point you in the right direction -
That error usually means that it couldn't find the method on the dispatch interface. You need to add your methods to the control class's dispatch table: you need to make sure
if you're using an MFC COleControl
(I'm less sure that this'll make a difference - would ASP need the TLB - but it's the correct thing to do and it can't hurt)
if you're using an ATL control

I'm using your advice for the MFC version. But I get this error:
