Greetings,
Just to minimize any misunderstanding concerning the C runtime, I think
the following page might help:
http://stackoverflow.com/questions/2766233/what-is-the-c-runtime-library. Note,
in essence, that this is a set of components needed for C or C++-based
applications to communicate with the Windows operating system. The C
runtime has nothing to do with .net (unless the .net component needs to
make unmanaged calls to the OS). Higher-level scripting languages such
as VBScript and JScript cannot make direct calls to the CRT, though it's
possible to execute VBScript and JScripts from a C/C++ application. More
fully featured scripting languages (e.g. python) have mechanisms for
directly accessing the C runtime and dealing with native C data types.
Note, though, that doing this also requires you be intimately familiar
with how the operating system manages memory as accessing the OS at such
a low level requires you to manage your data as needed. For instance, if
you instantiate a pointer and associated memory for an object on the
heap inside a function, both the memory and pointer must be cleared once
you're done with them.
So, while it's important to ensure your program is bundled with the
appropriate C runtime, it should only be necessary if you're
distributing an application which was compiled with a version of Visual
C++, or, in Bruce's example, you're using a python freezing tool. As the
python interpreter is itself a C program, it therefore requires the
correct runtime be available.
If you're not distributing a C++ program, then you don't need to worry
about the C runtimes.
Regards,
Steve

Hi Again Bruce: OK, I reviewed the MSCRT dll and found out what it all
means and understand what you are trying to do.
I am not sure you can hook into the MSCRT dll from within a VBScript
in any case but I could be wrong.
There seems to be allot going on in the Visual C Library which may
require access to framework objects - I didnt see that mentioned but
it sounds logical.
There is some kind of problem with VBScript where it can not do some
things and as a result cant tie directly into many of the Managed
Libraries which MSCRT may do.
The idea is great and, if it works, would provide some very nice
features to scripting but it is beyond me.
The only thing I could think of would be to experiment trying to
include it in a script somehow. If you want to hook into it via a C++
program I think that is doable enough then you could hook the script
via methods in the C++ program. I think it could be done in a C#
program but I didnt see anything on that other than a blurb on setting
some compiler options - and I am not sure that wasnt really suppose to
be for C++ since I didnt dig into the details.
Make sure you have a backup of your system if you muck about with that
puppy since I saw allot of olks who had major problems with it for one
reason r another with one of the symptoms not being able to boot up if
I remember.
Sorry I cant be more help but you are digging pretty deep into some
pretty cool stuff and I am just an old fat blind guy who does a little
application programming usually related to Financial Platforms.
Just out of curisoty let me know if you get it working as it may offer
some very interesting options to scripts.

Hi Rick,
I use all features of Python and the Trek Game, along with the
Battleship game, are both written in Python and I compile them for
portability
I had issues and problems when getting stuff compiled and had
the wrong version of PyInstaller. I think I got taken to the wrong
web site and that is always a problem.
I now have a real good working PyInstaller now and I can
compile on any of my computers, Python25 or Pyth0on27. The best
one is Python 2.5 and modifications were needed for Python 2.6 and
later and that is where it fell apart.
For the needed dll, MSVCRT is packaged differently for each
studio version, thus causing lots of problems when doing a
compile; fixed now.
I would like to write a dll for studio and I am using 2010 at
the moment, 2010 express.
I would like to make a hook for the MSCRT so the input and
display commands could be usable inside VBScript in an easy way.
I have bypassed that now with the keyboard hooks I posted the
other day by just making dictionaries for all the commands neeeded
for any project or game.
So, if you can help I would be appreciated. I thought I had
DLL info when first installing VS2010 but have been unable to find
it since.
Bruce

Hi Bruce: 2 things...
First, doesnt nvda use python to develop in? And, if so, do you
know if python has an easy access to either the MS managed UIA
features or if they use the Managed version of the UIA features if
python has access to the Managed Framework?
Second, you mention 2010 Express which sounds like you may be
doing something in one of the Visual Studio lagnlanguages. If so I
can help you with DLL(s) in vb.net and likely c#.net but I am
confused if you are working in VBA - that sounds like perhaps you
are working in Office Products.
Anyway, what do you know about python and accessing UIA features
if that is what you are doing.

Hi Chip,
there was nothing there that was of any use.
I will live with what I have. I may write an app and
compile it to be able to use Python for many things...
My 2010 express seems to not have any Dll stuff, I could
not find anything, but thought for sure I had found some back
when I first installed it but have not been able to find it again.
The key functions I posted are the best solution for now
and should work just fine. This is why I posted them for
anyone can define them any way they chose to either using 1
call back function or one for each, so will leave it at that.
Thanks, but have to do outside work and will have to pry
myself away from the computer because I spent the last 2 days
writing a simple mixer program which almost could be used as
a Python version of the PlaySound function/object with the
added feature of repeats and volume adjustment. It actually
works with a few minor bugs which can iron out some later day.
Thanks, Bruce

Bruce,
The first example I see is his ironcom.net, meant for sharing
some .net objects I think.
His other app I was remembering is named HomerJax, it
implements shared objects in Jscript. Due to an unfortunate
bug in GW's appGet however, this won't show up for you as a
choice unless you uncheck the "show English only" choice in
the appGet's "View" menu; the HomerJax app apparently has no
language specified, so it doesn't show up with the English
apps, and this is the default for appGet. Once you uncheck
this, you should see it in the "general" category.
Hth,
Chip

Hi Chip,
I found out you have to call a shell command, which I
think would work using the run command from a shell object
made in VBScript.
Also, the dll I wanted to load was the MSVCRT or future
ones, which are changing each time Microsoft writes and new
studio, so that idea died, besides not being able to call from
the dll which is always running.
Unless someone has come up with a way to call the MSVCR
dll properties and methods on this list.
which app examples did Jamal write or where are they, or
what are they called?
It certainly would be nice to use the Python sound mixer
apps because there much easier to use, including id and volume
control. They also use the MVCR dll by actually calling it by
name, for they wrote a module for it using the same name.
So, if you can give me the location of those examples he
wrote and I will take a look at them.

Bruce,
You can't from VBScript. I don't know Jscript, but I'm under
the impression it can use a DLL; if that's correct, you could
use it or Python and write some glue routines which are
shared, and have them call the dll. I believe Jamal wrote some
examples of shared Jscript apps.
Of course you could write glue routines in vb.net and have
them call the dll as well.
Hth,
Chip

Hi!
How do you register a dll for sharing inside the we object
model?
