C going to C++

[Kevin Torr]

I've been using C for some time now and I would like to take my first leap
into C++. I should warn you that I have little or no experience with visual
C++, though I do have some experience with different OOP languages.

I am using Microsoft Visual C++ 6.0.

I would like to create a very simple program to begin with:

A dialog box, say 320x240 in size, with file->exit and help->about menus.
Inside the box will be an input field where you type in your number, and a
button that says 'Go'.
Under that will be another text field which will give you 2* what you typed
previously if it's a number, otherwise it pops up with an error box saying
"Please enter only integers and decimals into the box".

So this is what I have done so far:
Created a new "Win32 application" project called "thetest".
I then create a new "C++ Source File" called "thesource" and add it to the
workspace "thetest".
I go up to 'insert -> resource -> menu' and create the menu
I save the resource as 'menu.rc' and 'menu.rc' to the 'Resource Files'
folder in the 'File View'

This is about as far as I can get without a tutorial or instructions to get
me further.
I'm not sure how to access the resources I have included to the project from
the C++ source file.

If someone could followup with either instructions or a URL that can run me
through this step-by-step, it would be very handy. Thanks.

Also, How do I remove files/resources from my workspace? There is no
'delete' item in the right-click menu!

Thanks.

Makes sense. I've done a fair bit of C command-line stuff, and the reason I wanted to move into C++ was because of it's GUI capabilities. Is there
really that much difference between C and C++ that I need to start from the command line all over again? :(

C++ doesn't have any GUI capabilities! Only products like Visual C++ etc.
have GUI capabilities. A straight C++ compiler will not give you that.
Visual C++ is a C++ compiler plus a whole bunch of Windows stuff built
together into a development environment. You can use the development
environment to organize your code and still write what are called "console
applications" in Visual C++. That's the only way you'll be able to use
"pure" C++. Otherwise, you've got 2 whole subjects to learn.

Well, all I had to go on (since I've never even heard of "Qt" before this
thread) was what Steven T. Hatton wrote, that "it is all standard C++".
As we've learned around here, Steven is never wrong.

Try not to trust blindly something someone said, since we all make
mistakes or missunderstand questions.
Qt may be written in standard C++, however you cannot compile a program
that uses Qt with a C++ compiler directly.

That's actually only partially true. You /can/ do everything moc does by
hand, and thus create a fully C++ Standard compliant program which could
also be compiled through the full Qt process using moc. The code written
to be processed by moc is (AFAIK) Standard C++. The part people seem to
believe is non-standard consists of macro invocations.
It has it's own preprocessor
that you must use before that.
That really isn't true. You /can/ do it by hand. Moc is simply a
convenience. So convenient in fact that not using it would be silly.
Now image what would happen if every
library out there required a custom preprocessing stage...
This argument is a bit spurious in view of the fact that most of the reason
for creating moc was to compensate for the lack of features in the C++
Standard of the time as well as the lack of support in the C++ compilers
for features that could otherwise have been used to achieve the same ends.
One a personal note, I prefer GTKmm when I need GUI stuff. It is as easy
to use as Qt (which admittedly appart from the signals&slots thing has a
pretty well-structured interface), but you can also use it through
standard C++

Qt has been fairly successfull. It doesn't look as though the Troll are
overly interested in tossing moc, though they seem to acknowledge the
technical feasibility of doing so. Mozilla uses a different approach which
is similar to moc in that it requires an IDL-based preprocessor available
(IIRC) through GTK.

I'm not wholly unsympathetic to your desire to avoid the proliferation of
additional preprocessors and other such gadgetry, OTOH, one might attempt
the same argument against using gnu autotools. There are partial
alternatives, to include TrollTech's qmake (a very nice tool, I will add),
but the gnu autotools have a significant track record of success.

There's also another argument for my favoring Qt. It may seem unreasonable
in terms of software development, but I suspect, in the big picture, it
makes a lot of sense. Loyalty.

First of all. Do you know how to do this in C?

This is all Visual C++ and Windows specific stuff. You'll have to go to the
microsoft.public newsgroups for help with that.

Second, why isn't this on a MS specific group?
