easy 500..

simple intraweb application has an active X on a form.
We know that the server owns all pages.. but is it also true for:
1. the activeX?
2. the data residing in the activeX.
im pretty sure the cost is for the TIWActiveX container itself..
but would like confirmation as the activeX may be 100MB of data per client. with thousands of active session.

The ActiveX is downloaded from the server the first time, and setup automatically in windows registry.

After that point, the activeX behaves exactly like another application, it can either have local data in files that it creates, or access DB, or do whatever you want (which is why it is a non secured technology)

when you are talking about cost, you mean what exactly ?
cost in bandwidth ?

I suppose you are doing something like this :

The 100 Mb of data, are they created by the activeX, using files ? if so they are local, so there is no cost for the VOLUME on the server

same as example.. but 1 major exception:
the data comes from other servers and not the IW server
the only part thing thats served by IW is the IWActiveX container.. the actual activeX is downloaded from another server alltogether, thus freeing IW resources.
the cost meanning the LIVE processeing data within the activeX on client's machine.
thuoght that since its within the IW container.. the server may "carry" the activeX.. but looks like its on the client's end.
so thanks !
BTW.. bob's activeX example does not work on BDS2010.. too many evolutions in  server coding since that version.
So the real question would be..
do i really need IW? or can i use standalone ISAPI  with pageproducer having a container rady made with those javascripts  to communicate with the activeX ?
if thats the case, then i wil open a quick thread for another easy 500 points  for a "skeleton"  ISAPI example with the javascript embeded.
if not, ill reward the thread.

Well, If you are using an ActiveX to deport majority of your process on the client's side, and that the data are on a DB on another server, then your Web server is nothing more than a convenient deploy & update solution. You could do that with a simple HTML page. What process do you still need in your Web server ?
If you need simple HTML but changing slightly (like different start parameters) from one user to another, then effectively ISAPI can do the trick nicely.

you probably right on the ISAPI  route, as i have to do some initial user authentication  and allow the axtiveX to receive the params.
I will open a new thread and reward more points
