Help with Vc++ PLEASE

I am going through the sams book, teach yourself visual C++ in 21 days, I am
on day 6 and I have run into problems, I am getting an error where it says
some variable doesn't excist which it does!!! and the main problem, I can no
longer compile, it starts compiling and then freezez, so then I can't close
it because it cannot close while compiling and so I have to close it from
the task manager, but since my task manager is acting up this makes it
hard... if anyone has the book or wants to look at my snip of code please
reply.

I'm not familiar with the book, but I'd guess that your problem is not
VC++ specific. That is, you'd probably have the same problem in any C++.

From the sketchy details you give here, I further guess that the problem
is one of scope and that your variable, while declared SOMEwhere, is not
available at the point at which the compiler complains.

A code snippet would help, along with an indication of the exact error
msg and the point at which it is thrown.

If the code is long, email it to me to save bandwidth. I'll trim it to
the relevant parts and post a reply here, in case others are interested.

No excuse tho for the compiler freezing (while compiling).

Ive had the IDE freeze on me untold numbers of times while
scrolling (mouse event overrun or something...)

I don't think I've ever seen my copy of VisualC++ 6.00 Professional freeze
or crash. Maybe you have bad ram or some other HW issue?

Leave it open overnight on a Win98 box, and a largish project
(400K-500K lines of code). The entire system will be dead in the
morning. No such problems with Win2000 and the same project, same HW.
[Yes, this is in my personal experience]

My recommendation: Win2000/XP are *SO* much stabler to develop
on. Switch to them if at all possible.

To justify charging 80 quid for a copy, MS put lots of unnecessary features
into VC++. You can change the font, you can play with the colour scheme, you
can dock toolbars and move windows around. All of this stuff makes it harder
to use.
There are also evil "time saving" compilation features. Fot instance, if you
get it automatically generate a skeleton app for you you will see a file
called stdafx.h mysteriously included. Try adding a file without stdafx in
it, and suddenly you will get the "precompiled headers not found" error
message.

The way to treat MSVC++ is to be terribly conservative. Not easy when your
software requires resources. Try not to do anything fancy so it doesn't do
something not properly tested by the folks at MS.

You've *got* to be kidding. In my experience the VC IDE locks up if you so
much as breathe at it.

He was talking about VC6, which in my experience is solid on
2000/XP. VS.NET is a disgrace of a UI, unstable (especially if you
have multiple instances open), and a complete mess. Give me the VS.NET
compiler in VC6's interface (which is NOT cloned in VS.NET), and I'd
buy it for home. If I didn't have to use VS.NET at work, I wouldn't
touch it.

Well, I can only speak for myself, and I haven't even had ONE lockup in all
the years that I am using it. At least none that were related to the IDE -
of course you will get a lock up if you try to debug past a
DirectDrawSurface Lock call, for example, but that is an issue with the way
DirectX works and has nothing to do with the stability of the IDE.

I did have crashes (only a few, though) but never any IDE-lockups.
