Re: Ah yes a C++ tutorial for VB programmers.
That looks exactly like a C++ for Windows book I read 12 years ago. Norm, there are no silver bullets. If you want to learn C++, your VB knowledge is worthless, and in any case, to learn C++ at this stage is pointless. Why do you keep beating up the same thing over and over? STOP. OK I glanced over this. It's stupid and useless for learning. It's all in the Windows environment and it's the Windows-ized C++ style, which is horrible. You can do the same things with VB by calling API functions, so what the hell does this buy you? Now for some real C++ on Windows code. \n// This is a part of the Microsoft Foundation Classes C++ library.\n// Copyright (C) 1992-1998 Microsoft Corporation\n// All rights reserved.\n//\n// This source code is only intended as a supplement to the\n// Microsoft Foundation Classes Reference and related\n// electronic documentation provided with the library.\n// See these sources for detailed information regarding the\n// Microsoft Foundation Classes product.\n\n#include "stdafx.h"\n\n#ifdef AFX_CORE2_SEG\n#pragma code_seg(AFX_CORE2_SEG)\n#endif\n\n#ifdef _DEBUG\n#undef THIS_FILE\nstatic char THIS_FILE[] = __FILE__;\n#endif\n\n#define new DEBUG_NEW\n\n/////////////////////////////////////////////////////////////////////////////\n// CMultiDocTemplate construction/destruction\n\nCMultiDocTemplate::CMultiDocTemplate(UINT nIDResource, CRuntimeClass* pDocClass,\n\tCRuntimeClass* pFrameClass, CRuntimeClass* pViewClass)\n\t\t: CDocTemplate(nIDResource, pDocClass, pFrameClass, pViewClass)\n{\n\tASSERT(m_docList.IsEmpty());\n\n\tm_hMenuShared = NULL;\n\tm_hAccelTable = NULL;\n\tm_nUntitledCount = 0;

Well it is a start
but you are right it did not cover MFC classes, etc. It is just enough to get my feet wet.
So should I stick with VB or try to learn something else at this point?

No, it is NOT a start
It's precisely the opposite - an END, the final disgusting morphing of C into something worthless and unusable by a company of monopolists who are primarily responsible for the current fetid state of personal computing.
C++ can be a decent language if used right. It it worth learning in its proper realm. But, first you have to know C. Do you? There is no way you can do C++ at any level without knowing C first. There is no way you can appreciate what C++ is trying to do without knowing objects first. Do you?
Why don't you get a Linux box going and learn Python? Haven't the brilliant programmers around here like Scott and Fu raved enough about it? It's actually USEFUL. What about Todd and his raves about Smalltalk? It's USEFUL. What about Ben and his Perl gems? It's USEFUL. What about Conrad and his Delphi? If you have to stay glued to Windows like a milky tit, at least get into a worthwhile idiom. MFC and C++ on Windows are the WORST CONCEIVABLE WAY to learn C++, GUI programming, and messing with it will drive you crazy. It's SHIT SHIT SHIT from the bottom to the top.
Don't trust me, compared to them I'm a hack, but I know enough to know enough.
You want me to tell you what to do? GET THE FUCK OUT OF WINDOWS AND MAKE A LINUX BOX.

Learning something new

I know C, I got an A out of both C classes I took in community college. I admit I am a bit rusty, and am relearning how to program in C. Like a muscle, if I don't use it often enough it gets weak. It will take some time to build back up. I looked at many C++ tutorials, but they assume the reader already knows about objects. Might as well be written in greek. I understand that a class is a definition of an object, and that methods and properties are encaspleated into objects. I also understand that new objects can be based on existing objects. Some things I am trying to grasp are polymorphism and inheritence. Objects inherit properties and methods from objects they are based on, is this right? Classes are also reusable and can help cut down on the development time of code by reusing objects from one program to another. All this is new to me and I am trying to digest it all without properly learning what objects are, as I never found a good source to explain it to me in plain English. So I pick up what I can from tutorials that already assume I know it. Of course I could have the concept of objects all wrong.
Why don't you get a Linux box going and learn Python? Haven't the brilliant programmers around here like Scott and Fu raved enough about it? It's actually USEFUL. What about Todd and his raves about Smalltalk? It's USEFUL. What about Ben and his Perl gems? It's USEFUL. What about Conrad and his Delphi?

MFC and C++ on Windows are the WORST CONCEIVABLE WAY to learn C++, GUI programming, and messing with it will drive you crazy. It's SHIT SHIT SHIT from the bottom to the top.
So many choices, Python, Smalltalk, Perl, Delphi/Kylix, etc do not forget Ruby, REXX, and many others. Not like throwing a lot of choices at me helps when I cannot make up my mind what to learn.
You want me to tell you what to do? GET THE FUCK OUT OF WINDOWS AND MAKE A LINUX BOX.
Don't you think I want to? All attempts to install Linux have met with failure so far. I am waiting until the current kernel stabilizes and is included in the distros. Then I have a choice on what distro to use, and yet again cannot make up my mind on it. SuSE, Red Hat, Debian, Lindows, Slackware, can't seem to find which one I want to use.

No I won't
most likely MS will charge $360 for it, and SCO will require $699 for a user license.
I just need to find the time to muck around with Linux again, last time took hours and wasted my time and fustrated me. So I am taking a big break until I have extra time to do so again. Last success I had was on my brother's system with Red Hat 9.0 but it would not run his games properly.

Pull the other one
You're either too lazy or too stupid to install Linux because deep down you love Windows.
At no point have you ever posted anything approximating a serious attempt to install Linux with proper problem reports and step-by-step stuff. Never.
If I can put Linux on an HP9000 D330 with no display hardware and a serial console and a network connection by way of connectivity, you can put it on a PC.

You pull the other one
I gave exactly what the screen said. I listed the hardware used and talked about how far the install went. I honestly have no idea what you think a proper problem report looks like.
I would use my Red Hat 9.0 disks, but support is going away. Fedora may be better to download then. Only it seems to upset the SuSE and Debian lovers here when I talk about using a different distro than they use. Lindows I had considered, but I'll have to buy a copy as it is not free.
I actually tried to ask other Linux users, not here, but on #Linuxhelp on a (shudder) IRC channel on what distro to use. No replies and I was ignored. Reminds me why I hate IRC so much.
I use Windows because I already know how to troubleshoot it, I can work through botched install. I cannot seem to work through a botched install with Linux, nor is anyone willing to help me without a proper problem report or whatever the f*ck I got to do to get help, secret handshake, passphrase, and taking an oath to never run Windows again. :(

Linux takes study
to use it. It WILL require a level of dedication from you.
If you don't want to use it, or you don't want to put the effort into learning it, that's fine - don't use it.
As for which distro - pick one. I don't care, and am not going to get pulled into a debate on which distro is better. However, most of the people on here know debian and will help you with debian problems because that's what they know. (Asking Redhat questions to Debian users isn't going to elicit a multitude of responses).
But the first question must be a desire to learn. There is NOTHING wrong with not wanting to learn Linux. If Windows works for you, why switch?

Why switch?
Actually I want to be able to use both. Get the best of both worlds.
I will put in the effort to learn, but my time set aside for learning is limited.
If I download Debian, will I get help from here? I am willing to fill out a problem report, if someone sends me a blank one.
I am trying to figure out DragonLinux, I did a search on distros and found it interesting. It should be one of the most painless to install due to its nature and simplicity.

No choice
You don't have to make any choices - just follow my directions to the letter. I don't even have to visit you. Once you are up I can remotely set things up with VNC or even simple telnet access. You get a Linux system, configured by an experienced person, and then you can go to town.
The differences in distributions are not important enough for a newbie to be showstoppers. They all have good and bad points.
Repeat: send me a detailed hardware report on the target system and we'll get started. You don't have to do anything at all.

I have to go out of town tomorrow and then study for a final exam. Will this be SuSE? Also give me some time to get data off the 98SE system before I get ready to format it.
For VNC access, I'll need the port number to punch a hole through my DSL router firewall.

How 2 pick a distro and get running today
Step 1:
Go to the linux forum.
Step 2:
Ask which distro most people are using. Be sure to post what kind of hardware you want to run it on.
Step 3:
Select a recommended distro and make the individuals who recommended it your coaches. Put them on the hook for walking you through it. Post specific issues as you go. You will have a working linux distro within a week (probably in a day) with this approach. You just gotta adopt a coach and keep after him. I think I see Peter volunteering in another message BTW...

But thanks for the compliment. :)

As soon as you stumble across: \n#define new DEBUG_NEW You start to have your doubts about its veracity as real C++. But then, the kicker: \nCMultiDocTemplate::CMultiDocTemplate And you've exitted the world of C++ and entered into the byzantine parallel universe of "Micros~1 C++ surrogate", where, to quote the old song: "The rules do not apply". jb4

I'm not saying it's "good" C++, just that it "is" C++. Windows is the eternal monument to C++ in the Real::World.

MFC and its templates, documents and views
is a huge unwieldy solution in the search of a problem. It allows you to write a generic "editor" with OLE, print preview and all the trimmimgs in 50 lines of code (not counting 5000 generated lines behind the scenres). Trouble is, nobody writes generic editors. And MFC is useless for anything else.
