Re: Win32? MFC? .NET? What to use for embedded dev?

Cool! That is a new approach to me. The more feedback the better.

I greatly respect Sean but I'll offer a different perspective. I had a
background similar to yours -- primarily Unix and "true" embedded systems
before I came to XP Embedded. For your application (which is similar to
mine) I see no real advantage to buying into any of the Windows programming
paradigms, i.e. .net, MFC, win32, etc. I prefer to do everything in what
is basically a POSIX compliant paradigm using stdio, standard
(Berkeley-like) sockets, etc. This leaves open the potential for much
simpler porting to a different OS should that prove advantageous. From
what you described I think the only thing that can't look quite standard is
thread creation and control since there are no pthread-like calls available
but you could easily create wrappers around the win32 thread functions.
Also, I don't use any Visual Studio project type and instead I use my
favorite editor (vi) and makefiles. When it's necessary to use the VS
debugger this approach makes things only a bit harder but for me it's worth
it not to have project files and the other encumbrances of VS.

I'm not claiming to be an expert in making these judgments so if anyone
can tell me why I've missed something valuable in the Windows paradigms I
would be a grateful listener.

1. That's what I had thought (that paring down features might possibly
help).
I guess I was wondering if people found this to be the case in general or
even if there was some anecdotal stuff like "disabling the windows shell
gave
us a 5% performance increase".

2. So people do use MFC and .NET for their embedded apps? Is using Win32
a
bad idea? Also, I forgot to mention the app needs to be C++. Can you
recommend some good current Windows C++ programming books (for Win32, MFC
and/or .NET)

Thanks!

on what you are doing.

2. It didn't take me long to get familair with .NET programming. Start
with
a console app and try an MFC applicaitons. There are lots of getting
started
books on C# and VB.NET. MS Press books have som pretty good C# books
out
there: Inside C# v2, Visual C# .NET Step-By-Step, Progrmming Visual C#
.NET,
C# Programers Cook book to name a few.

Howdy,

I need to develop an embedded Windows application. I'm an experienced
C
and
C++ programmer with predominately an embedded and unix background, but
in
terms of modern Windows software development, I've got a lot to learn,
so
I'm looking for some tips on how/where to get started. I'll be using
C++
with Visual Studio 2005. The app will require several different
threads
collecting/analyzing data and performing I/O. It doesn't require a
gui; a
console/text output window is fine.

Some questions:

- Is there any performance benefit to using XPembedded versus regular
XP?
(Sorry, I asked a variant of this before but that part wasn't really
answered).

- What is the best starting point might be for me in terms of
technologies
(Win32, MFC, .NET)? My first guess is to start with a Win32 Console
Project.
But I just saw some stuff about MS "deprecating" Win32 in favor of
.NET
framework. Do I want/need to use something like MFC or .NET for what
I'm
doing? Any benefits? What do developers typically use?

Beyond that what are some good books/online resources to learn that
stuff
and to serve as a reference? (Ie: If .NET is the way to go, what are
some
good books to learn it from?)

Thanks!
