Hello all.
I would like to build a visualizing software (for some hardware i have built)
In my opinion i have two ways :
1.) Building my own Visual-Server and a Visual-Client. The two communicaten with TCP. And all is fine. (Is better because the Client gets notified if something changes and not to poll every second, the graphics looks better, all in delphi - easier to develop for me)
2.) Building it with HTML. Writeing some components for the server. And some classes for the client. (Is better because of changeing components or classes without change the whole application, independent about the system (linux, win, ...))

What do you think is the best way ?
If its the first - no more questions
Is it the second :
I am useing Delphi 5 Enterprise.
*) What components do i need for server side.
*) Have i to build my own HTTP Server or implements some components into an existing one ?
*) Have the client to ask every second for the Page ? Or can the client be notified if something has changed ?

Be happy for any comment !

Visualizing  - (don't know if it is correct spelled)
I would like to show some data on the PC for example :
Temperatures in some rooms, If the door is opened, if the window is open, if the light is on ....

Umm... if you are talking about intrumentation, well you could perhaps check out Varian Workshop... it contains various visual components that you may use.

http://www.varian-software.com/products.html

And if you want to web-enable it... perhaps you could convert them to ActiveX? Just a thought...

Option 2 may not be so desirable because you have to
code everything with HTTP requirements in mind - remembering that your little client device is gonna
need to talk to a fully-fledged Apache or IIS or whatever
server.

I'd opt for option 1. It ensures tighter control on
client-server communication and has a lot less overhead.

Ofcourse, the other consideration is what kinda environment
the visualizer is gonna be used in. If you want it widely
used eg. on a LAN or something then maybe HTTP IS better.

The whole project sounds like a lotta fun, though.

Let us know how you get on.

If you're doing JAVA anyways, why not visualize using a proprietary approach (your 1. approach) but display it in an applet? This would take care of your compatibility concerns and still would allow the flexibility of 1.
