Ok Jim, sorry -- however I'm not sure which of my emails you want me to
translate. The last one was just a reference to the well known scripture in
John chapter 1. From what you said in your mail about how programs were viewed
in python, I thought the resemblance to these few verses was rather
interesting. I hope no one is offended.
So what did you want me to say in English, and what in programming?
I am not familiar with Python syntax.

Hi Laura,
Were you able to translate anything I said into programming-speak? Can you
please help translate the stuff you said into English for me? I don't know why
I'm so hung up on this stuff. I frustrate myself.

so, "in the beginning, there was an object..." *smile*
just kidding.
thx

Hi Laura,
If I understand how it works correctly, Python has one object that has
certain things in it. It has a name, but I can't remember what the name is.
When you run your program, this object thing comes along with it somehow. You
can get a Python prompt and type in some function call or other and use the
name of the main object as a parameter. Output will come back and tell you all
the functions and properties it contains. One of those objects will be your
program.

ah, ok, so python uses that paradigm. Does it consider executable
statements to also be objects? How about types? Do you declare objects to be of
a given type, or is everything typed on the fly? And are the types attributes
or are attributes objects? LOL you have to have some basic special objects that
do certain things, or you wouldn't have a language.
I was going to use python in a little program just to learn it. It sounds
like an interesting little language.

In Python tutorials, they go to great lengths to stress that EVERYTHING
is an object. I have trouble expressing or even getting my head around their
examples. But they make it clear, EVERYTHING is an object!

I wouldn't call everything an object -- it is true the word "object" is
overused and has been applied to many things. But in OO programs, it is a set
of data coupled with "methods" or functions defining operations on that data.
In the OO languages, all built in types declare objects -- for example,
something as simple as an int variable is an integer object with operations +
and - and you know the rest.
The most general object is one of a "class" type. This in C++ is a
glorified struct with specialized data and member functions and inheritance
from base classes whose data and functions you want to apply. It is similar
with other OO languages.
An object in my learning of the term is an instance of a type -- that is
a variable or constant declared with that type.
Perhaps the more recent textbooks redefine the term. I'll let other list
members correct the holes or errors in my definition in modern parlance.
And of course there are interfaces and templates and other beasties you
need to learn in the various languages, generalizing types yet another level.
So happy hacking. For the procedural programmers accustomed to COBOL or
C or fortran or whatever, I hope this is a helpful intro. When I first made
the transition from procedural to OO, it was like turning a C program
inside-out -- or rather, OO style localized and hid more details of an
implementation so the C version was like inside-out C++ with nits all scattered
far and wide, even if the C program was well thought out.
Happy hacking all.

Hi Jim. I was doing COBOL when you were still watching Barney - Grin! I
started programming back in the 1970's with Cobol and all that MainFrame Jazz
so know exactly what you mean. I will be addressing OOP which is really nothing
more than thinking of everything as an object. A Subroutine is an object, A
Function Is An Object, An Array is an Object everything is pretty much an
object. And, objects have properties you can set and often they have methods
which are themselves subroutines or functions. Anyway it is not a somplex as
the gurus make it sound, it's pretty easy and intuitive after you play with it
a little.

Hi Rick,
First of all, thank you very much for taking the time to do this.
Secondly, please don't skim over the object stuff. Speaking for myself, I'm an
old Cobol programmer who has trouble thinking that way, so I need to get over
it. I'll subscribe to the list from home, which is where I'll load the tools
and do the work.

Hi Guys: After the postings I think the following project will hhelp
get things off
the ground.
One:
We want a modular project so folks can pick and choose what they want
to include in
it and allow for skipping modules without impacting later modules.
This way you can
pick and choose features and technicals to include in the project.
Two:
Start from the very beginning building upon our experiences.
Three:
Use both Vb.net and C# ( Pronounced CSharp) if possible.
To this end I will build a series of tutorials this weekend and into
next week
comprising Module01.
Module01 will just build the project and set up some fundemental
building blocks we
can expand on later.
It will consist of 4 Tutorials:
tutorial01:
Step01
Set up the IDE for Accessibility using my settings, those on jamal's
or the Elf's
site or your own settings as you prefer.
Step02
Add a ShortCut to Vb.net or C#.net to our DeskTop or whatever the
same thing would
be in Vista or Windows7. this way you can just click a DeskTop Icon
to open your IDE
for working on the project or any other Vb.net or C# project you
build.
Tutorial02:
Step01
Create A Project named WinformBasics or one of your own choosing and
Structure the project by adding a Utilities Folder with a Globals
file and a Logger
Utility for use throughout all the subsequent modules.
Tutorial03:
Step01
Add a Windows Form called RootForm to the project and set some of
it's properties.
Step02
Make rootForm the Default Project form and get rid of the
automatically generated
Form1 Windows Form that was added when the Project was created.
Tutorial04
Add a MenuBar to RootForm with a Menu called HotLinks.
Add one or more links as pull down items to the HotLinks Menu that
will take you to
someplace, Websites in my current thinking.
Once we have Module01 up and running we will discuss the next set of
tutorials which
will add a second menu to the MenuBar of the RootForm.This Module
will have features
that will demonstrate basic programming techniques like working with
strings,
Arrays, Looping and anything else you might have questions about
regarding the
fundemental Vb.net or C# statements. It might prove cool to use this
feature later in another series to create a project to display programming tips
and snipet code for complex issues and would fit well in with a DataBase
tutorial series if that is how you want to go later on.
we will also touch on creating a Class with Subroutines, Functions
and Properties and see how to use them. This is for the Raw Beginners and
unless otherwise indicated can be skim read by more experienced programmers
before we continue to the Third Module where we can dig into OOP more in-depth
or go into using Data Files and, or, a DataBase. So, look for the WinformBasics
project with 4, or so, file attachments. They will be txt files you can copy
and save. I think this is easier than trying to use the tutorials directly from
inside a e-list posting and how I
have done it in the past. Well, unless someone yells out Stop! I will
try and get something up this weekend and have this first Module done by the
end of the week.
Remember to speak up about anything because while we are on one topic
we can all discuss and have input into the material learned. Post up any tips,
suggestions or
questions while we are working on a module to help make this series
the best it can be in a short timeframe.
