Visual Objects compared to Visual Basic and Visual C.
Who can explain me why I have to use VO instead
of VB or VC? OR is is there no difference?
With kind regards

Every language has his (dis)advantages. The ones you mention are all
wrappers around the Win32 API.
VO is a very nice and easy language compared to VC. Data-access is famous
with VO, but also memorymanagement, the cargage collector, ragged array's.
and the result is fast and reliable code. You do not have to declare every
variable if you do not want to. (but you will)
Comparing to VB is VO a real OOP langangue where VB is not. You can write
your own classes, inherit classes from VO classes or from your own classes,
Overide methods, use both strong and loose typed variables, write early and
late bound code
VO comes with a SDK containing the sourcecode of the part of VO written in
VO (almost everything except f.i. the compiler)
With VO you get this newsgroup, where almost every question is answered
VO has a prof. usergroup in the netherlands, check www.sdgn.nl. with very
often very well organised conferences. I think it is the best organised
usergroup in the world.
VO is limitted to the Win32 api. A .NET version is announced, but withoot a

Import in VO appears to want MEF files to import into the app. I have a Clipper app that I need to import into VO (and then into Vulcan.)
File / Import in VO asks for MEFs. Do I need to someohow convert the Clipper PRGs to MEFs? Any help appreciated. The cavo docs don't seem to mention any of this.
The "bad" news first: There is no direct way to import Clipper Code to VO.
Clipper is a procedural character-based program language and VO is a event
driven graphical Windows development system. This are two almost completely
The somewhat better news now:
There are some possibilities to go from Clipper to a graphic user interface:
www.alaska-software.com has something like this.
Try to find the solution by Google....

I have a macro on Ms Access 2000 with an action: SetValue;

form is opened when the SetValue action is called, but I get the
following error :"The object you referenced in the Visual Basic

The problem is that I have run this code on several PCs, but no error
was ever reported except on 1 PC. So I don't expect the problem to come
from the macro. Could it be something about the settings on Access or
about the installation process?
May be the application that the OLE-object refers to for opening the
OLE-object is not installed on that PC ? (just a guess, I didn't verify
that particular error-message)

Hello to everybody,
I was wondering if it's posible to design a DataWindow with controls
(Single-Line Edit, Multi-Line Edit, etc) with a similar behavior that
it's seen in Visual Basic .NET when using the "Anchor" property?
What does the Anchor feature do?
When you set the controls in VB.NET forms, you can properly resize the
controls based on the size of the form.
For a better explanation of what this property do (because my English
is so poor), you can watch the following video:

not know why. XP SP2, Windows Media Player 11, IE 7.

I wonder, what are the common ways of implementing an (object,
object) -> object mapping in Scheme (of various flavours)?
Say, I have a set of `shop' objects, a set of `item' ones, and
then a mapping, like: (shop, item) -> stock. With an option to
get an (item -> stock) mapping for any given `shop'.
One of the solutions (in standard Scheme) would be to embed a
mapping into either each `shop' or `item' (or both), and then,
(define (get-stock shop item)
(assq item (shop-items shop)))
(define (get-stock shop item)

Consider the following
frisky is an object yet frisky is also an object type.
frsiky is region of storage yet frisky is also an identifier.
frisky is also a Cat type.
An object is an object type, that is why it's called an object.
An integer is an integer type , this is why we call it an integer
There is no instantiation here, yet there is an object.
The object declared here is defined by the definition of its type, in the
If Cat has an Eat() member function then frisky has an Eat() member
If Cat has a Meow() member function then so does frisky. And so on.
The term object is not simply a block of memory. Whether the inconsistent
standards state this or not, which they don't.

Wrong due to oversimplification.
