Win32

Win32

[Brian Catlin]

I need to write an image processing app that reads frames from an Intel CS330
USB camera on WinXP.  I was planning on using either the Windows Image
Acquisition (WIA) APIs or the TWAIN APIs.

Can someone recommend a Win32 binding (thick or thin)?  I looked on AdaPower,
but a lot of the information on Win32 is a few years old, and may not be up to
date

Try getting something that has a COM interface and auto generate a binding
with bindcom (from www.adapower.com)

For example, running the dll inside the library here

http://vbnet.mvps.org/index.html?code/imageapi/mswaidll.htm

produced a pretty readable binding. (assuming you are used to win32 code)

A little sweeping! I have the gnatwin package installed
(ftp://ftp.cs.nyu.edu/pub/gnat/3.15p/winnt/), which includes WIndows
API bindings, though I've not used them yet; as you might note from my
other postings I'm looking at the .net bindings at the moment. I'd
guess that the biggest issue with gnatwin is likely to be the gnu
license which may not be suitable for your purposes.

GNAT uses the LGPL, easily the most flexible licence around.

I have done quite a lot of programming with the Win32Ada bindings, which is
available both for GNAT and for ObjectAda. It is a very thin binding to the
Win32 API services. It looks sort of ugly, but to those who are used to
Win32 programming in C, it looks very familiar.

Oh? Have they changed? I thought they use the GMGPL?

Things have not changed..Though I have seen some people post libraries that
do GMLGPL ! Which is a little odd and I dont think works out to what people
think
it works out to.

Interesting. Are you marketing your mind reading skills?

I use the GMGPL for my releases, and I know _exactly_ what it means.

I know..I am sure you do.And GMGPL is pretty well understood.
I am saying that I recently saw a library with a GM L GPL
(The LGPL with the GNAT exception)...

Ah, sorry, missed the extra L. That would indicate they aren't
thinking (or reading) straight!

  Absolutely.
I have an Ada Claw binding to Video For Windows, which is pretty old, but
has the virtue of running on older things than Windows XP.  You're welcome
to a copy if you want it.

Amen! This forum has had several threads where we have discussed the
omissions , errors and lack of updates to the Win32Ada binding. The problem
AFIAK is determining who is responsible for Win32Ada. Frankly, I would love
to see this become a SourceForge project.

So do it! 

Win32Ada carries a Microsoft license, so you can't start with that.
But you can start one from scratch, or from GWindows, or from Windex.
Nothing is stopping you.

This one is very good : self-explaining, coherent, nicely and scalabily
object-oriented. Some parts of Win32 are not (yet) there, but you can complete
it easily. In the same area GNATCOM can produce automatically bindings,
maybe it will do the trick for your API's.
