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.
