real time apps

Hello,

I'm a serious cross roads right now.
All my in house development to date have been mostly Java and very little VB 6. I have to make a decision if I want to continue VB support in the form of VB.net.

The deciding factor will be VB.net real time application capabilities.
Java, as many of you may already know, is woefully inadequete when it comes to real time applications when compared to C++.

How is VB.net in terms of real time data handling?

Ideally, I need an application that will be access a COM object that will continually supply data to my app. The app will also be accessing a SQL Server for additional data. How much data can the VB.net app take on?

As much as you feed it. :)

VB.NET is well suited to 2 or 3 tier app development. Accessing a COM object will be less than optimal, but can be done. Ideally, you would rewrite the COM object as well.

Thanks for the info. I imagine that any book on Windows Form programming will be suitable for a real time app?

.Net has nothing to do with it. Windows is not a realtime OS.

OK. My ignorance is shining right through.
As you can already tell I'm pretty unfamiliar with VB.
I thought in VB.net you can create a windows form projet that is pretty much a vb project meant to run as a windows application.

Am I wrong?

Yes you can. But that doesn't make it real-time. To create a 'true' real-time application you have to use an OS other than windows. Chances are your using a different definition of 'real-time' though.

Ahh. Yeah i don't mean the app has to run while being compiled.
It can be pre-compiled. The data just has to be real-time.

Is that what is causing the confusion?
