Hi

I'm trying to run a component as a WebService, but my
component include a windows GUI, and it seems that when
running as a WebService the GUI is not displayed on the
screen, and I need it. I believe that it is because the
IIS is running as a SYSTEM user, but I don't knoe how to
solve this.

Therefore I will try to expose the component using
Remoting. My questions are now:
Will the GUI show up when it rums as a remoting server?
What about firewall issues like opening ports on the
client side, is that an issue?
Why, or in which situations, would you shoose HTTP
instead of TCP as the remoting protocol?

Thanks

Hi,

> Will the GUI show up when it rums as a remoting server?

here is a previous reply ..
"you can remote any object that inherits from MarshalByRefObject.
Since
Windows.Form inherits from MBR you should be able to remote it. But
note
that 'returning' a windows form would actually return a proxy to the
actual
remote object(windows form) and not the actual object."

that shouls answer ur first query ..

In this case .. since u want to display GUI looks like u'll have to
use remoting .. as for HTTP vs TCp .. if its behind a firewall then
u'll have to go for HTTP and SOAP. if its on the intranet u can go for
TCP and binary formatting. u can go thro some msdn links for more info

these will give u performance ratings between web services and
remoting ..

Just to be clear for others, you can also use TCP over the INET and your
firewall, just need to set the firewall respectively.

thanks william for pointing that out . yes u're right about that ....
i havent tried that out as yet ..one of the reasons y i skipped it :)
But how do we go about setting the firewall..? and if its a simple
affair .. then wont going thro TCP and binary formatting be a better
option when compared to HTTp and SOAP..?

Wait a minute, does that mean if you use HTTP it uses
port 80, and can pass a firewall?
As I remember you still have to specify a port both for
HTTP and TCP, and that will require that both the client
and server must open that port?
Is the TCP faster for large binary data?
