Re: Remoting - how to access server data?
The follow the link...that I have at my Remoting Post.
He discusses why.....and refers to a "super particle beam" thing in jest.
..
But .... you can do the same thing with WCF, via my "WCF Interfaced
Development".
You're letting the "Host" do the data collecting, and then pushing the
collected data to the client.

Re: Remoting - how to access server data?
You may recall that I did admit to being a newbie in dotNet. Of
course WCF seems to be dotNet 3.0 and I am currently tied to Visual
Studio 2005 and dotNet 2 and don't feel like shelling out another
thousand bucks or so just to be that current. My socket TCP/IP
messaging has worked well through Dos and C through Windows and C++
and translated easily into dotNet and C#. There is a limit on just
how much I am willing to upgrade the infrastructure of the project if
it doesn't show up in the user interface where you can far more easily
justify the cost. There is always the response "it works now, why
should I pay X thousand dollars extra to get the same thing?". Yes,
the infrastructure is the most important part, but it is also the
hardest to sell.

Re: Remoting - how to access server data?
3.0 is an "addon" to 2.0. It does not require a new version of VS200x. It
works with VS2005.
The framework is free.
The CTP is free.
So there is not a financial reason not to do it.
3.0 runs on XP, WinServer2003, Vista and WinServer2008.

Re: Remoting - how to access server data?
That should do it. As that site says, "like most new technologies it
might not be obvious how one goes about experimenting with it for the
first time".
I am using the time until they give me a P.O. for the new system to
upgrade my skills, and the farther I can get (with moderate but not
excessive stress on my part), the better the result will be. WCF
sounds like the appropriate technology and I now have enough tutorial
information to go on my on.
Thanks a real big heap. You have been an enormous help.
