Re: Problem with using ConnectionManager API on Win CE (pocket pc)

Hi!

Configuring the connection manager - well, that's what gave me a few grey
hairs until I'd got it right. Unfortunately, I'm working on MDAs in with
german platforms so I can't tell you exactly what to configure on your
device.

Typically, your browser has some settings concerning server, adresses (ip
or name), pop-server, proxy etc. so the connection manager does not need
to know any of these to be used for a successful connection.
Your application, on the other hand, does - normally - not know any of
these so the connection manager has to have that information configured
(something like options - advanced ... proxy config ... I don't know as
I've got a different platform).

On my MDA, I have configured 2 networks - one to be used by browser /
mail which looks rather straightforward and one for our company network
with server adresses and all that to be used by our application.
Miraculously, the OS always choses the right one though both of them are
allowed to be used by programs :-)

I found the following web page to be quite helpful:
