Hi Steve and Rick,
Just got home and read all the comments and yes Steve you have to be
careful for as I had stated, studio changed that run time dll each new version
they came out with. The original Python one only uses the MSVCRT with no
number, but as both progressed, into Python 2.6 and later, along with studio
from 2010 and later they started adding numbers to that dll and those run times
have to be compatible, but I suspect it depends on what you want from it.
For I discovered that some of it is reverse compatible and I was really
only interested in the input command, and the display command, which are
MSVCRT.getch and print respectively in Python.
It is not a big priority since I can use the hotkeys since there the hotkey
is assigned to the given window you want it in, which is perfect for what I
need. The rest is how not to use up CPU time while waiting for an input.
I will check on that link Steve, but I suspect I have already read it.
Rick, I will take a look at what you suggested since I have not yet
experimented with projects in a major scale, just simple events and such at the
moment. I was searching for the documentation on how to set up, make a DLL and
was certain I had all that information from the knowledge base at the beginning
of the semester when searching for the information on how to compile C++
programs and run programs without using the IDE. For it seemed the DLL stuff
was with the needed command utilities to compile from the command prompt which
I did all semester in the C++ course. For all my programs were written using
that and all of them are now stand alone programs or .exe files. I had to
upload both the text or .cpp files along with the .exe because of the issue
with notepad changing back and forth from ANSI to Unicode formats which seem to
happen at random. My professor was using a non-Windows compiler and it did not
like Unicode formats, but Studio was all fat dumb and happy with either format.
I just want to spend the summer working with DLL's and what I could extract
from them.
Yes Rick, it would be nice to get at least some of the commands from that
library, but as Steve hints at, Script was designed to prevent people from
using certain commands that would give hackers the ability to hack your
computer and act as a local user...
I did read up on the memory stuff this week and it does gives examples on
how to set it up and make sure you call the proper command to destroy them, so
no memory build up happens and lock up the system if still referenced...
It is my learning tool, using games as my motivation, then the rest comes
from there; just like the text book examples do.
I got an email from someone to make the cuckoo clock program as a stand
alone without a screen reader and that could be done using the same commands,
just spelled differently and having it all come for a simple web page that is
running all the time; I think that is kind of how things are done anyway, for
lots of the commands are almost identical, just spelled a little differently.
that person is an assistive technology person who was asking, since some of
his students do not have a screen reader program.
But, once the DLL is mastered then more hooks can be made and who knows
what I can write at that point for Windoweyes.
Thanks guys, will start reading again.
Bruce

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.

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.

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.

Chip

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