asp_components thread: COM & HTM

Hi
My question is really related to com and htm/javascript, since the book
is for asp I'll ask the question here, as Im not sure exactly where else
to post this.
I recently developed the com object from chapter 2 of beginning
components for asp WX2882, but when I use the object tag in a htm file
to reference a dll, how can I use this in a client/server environment.
Firstly I registered the dll on the server, then realised that calling
it from a server it would load onto a client machine and that it would
have to be installed on the client machine, I have the object id,
classid, and codebase all entered correctly yet the I kepp getting a js
error- object doesnt support method or property- what am I doing wrong??
any ideas welcome

You have IIS running as your web server. What you would like is for the
dll to be run on the web server, not the client computers. To
facilitate this, you need a page that will have some server side
processing inside it. Htm/html files by default don't offer any server
side processing. Name you page with the .asp extension, to let IIS know
that it should pre-process the page before streaming the page requested
to the client. Inside the asp page, any code you want the server to
look at should be wrapped inside percent tags like this:
<BR/>
This is not processed
streamed directly to client
<BR/>
<!-- begin asp code -->
<%
' <--- notice less than & percent sign
' this queues asp to react
' embedded code
' iis will look at
' and process before
' it streams to client
Dim objMyObject
Set objMyObject =3D CreateObject("someobject.someclass")
Response.Write objMyObject.SomeMethod (input)
Response.Write "<BR/>"
Response.Write objMyObject.SomeProperty
Response.Write "<BR/>"
Set objMyObject =3D Nothing
' <--- notice percent sign & greater than sign
' this queues asp that this marks end of code segment
%>
<!-- end asp code -->
You can have multiple tags like this in your asp page.
The dll will run on the web server and does not need to be installed on
client boxes.
I suggest you look into using MTS (Microsoft Transaction Server) if you
are going to be writing dll's for use by web server. But that is a
whole other topic, which won't effect your asp code ...

Hi
Thanks for your answer but unfortunately I wish to call it from
javascript/htm if possible, I have it working through asp in another app,
but am interested to see if it would work on a client/server machine
without IIS and therefore reduce the requirements of the app (i.e.
customers wouldnt need IIS)

Hi
Thanks for your reply
2 ways ive tried it
First way with a cab file, code is
<OBJECT ID="WX2882db5"
CLASSID="CLSID:3ED9D65A-E79B-4535-AD3E-CAD6D3CD3E3C"
CODEBASE="WX2882db5.CAB#version=1,0,0,0">
</OBJECT>
var dblPremium = WX2882db5.GetPremium();
2nd way
<OBJECT ID="WX2882db5" CLASSID="CLSID:3ED9D65A-E79B-4535-AD3E-CAD6D3CD3E3C"
CODEBASE="D:\com\WX2882db5.dll">
</OBJECT>
var dblPremium = WX2882db5.GetPremium();
when I run these from the server machine locally, or copy them to my own
machine and run locally they're fine, however when I run them on the
client both ways , even if I register the dll on both, I get the same
error- object doesnt support this method or property.
I know its probably something simple, but I just cant get it to work.

Hi !
As far as I know if you want to use some object on client machine it should
be installed there.
Now first case I don't think its goanna work unless WX2882db5 object will
exists on remote client machine.
Second case, you should try to change CODEBASE="D:\com\WX2882db5.dll"
to something like CODEBASE="http://your server"
cause when you say "D:\com\WX2882db5.dll" it will try to find it out on
local client
computer and not on your server.
Hope it will help.
Oleg

Thanks alot for your comment I changed the codebase to
CODEBASE="http://myserver" and enabled activeX conrols to prompt for
activeX controls not marked as safe, it now works perfectly!!
On another note is there anyway a dll could pass out info to the server,
as well the client browser without using asp??
Thanks again for your help

Hi again !!
First of all there are always a way to do whatever you want to.
I never did it but may be you should think about using sockets in this case.
You'll have to build some small client program inside DLL that going to be
on
client machine and "server client" that going to reside on server machine
and talk with all your
clients, but you'll also have to consider multi-user environment, so you
"server client"
will know how to handle more than one user.
Oleg.
