Okay.
I will begin with one general issue. I am not exactly sure where to map command and command UI, but most important, messages in general.
Mainframe and documents can only handle command/UI messages. I cannot decide where to map command/UI mainframe, view, or documents.
I am very rusty on classifying different messages, but that is not a problem because I can always look them up in Promise's book.
The last issue I am not certain of is all the painting tools. Promise discussed a lot of core materials in the first five chapters. I lost sight of all th painting tools along the way.
Yes, I read everything very carefully. There were just too many new materials to remember without having any prior knowledge MFC to use each tool as Prosise present it. When I was learning C++, I was able to read the new material and immediately apply it in a real program. That is how I learn, and it is when I am at my best. With MFC, I learn that "k" is a letter, but that is it. I have no idea that "i" and "j" are before and after "k."
I really enjoy reading about document/view because it is something I caught on quick. I understand that architecture. It is the tools around MFC classes that I do not understand. The two pages of classes and functions in the first two pages of Promise's book hurts my brain.
Now, the program I am working on has to do with read data from a text file, analyze the data, and output the modified data back to the file. For example, the program will read "a" and output "Letter: A."
I am not sure the exact CView I need (scroll, edit, etc.). I am not sure what message I need to consider and what to map them. In general, I am not ready to implement the win32 console program to windows using MFC.
Thanks,

Messages are generally mapped in the class that relates to them - in other words, map messages to do with loading and saving files in your document class, map paint messages in your view or dialog class. As far as internal messages go, it's a non-issue because the class wizard will only show you the messages you can use anyhow.
Command/UI messages should be mapped in the mainframe, because it's always there to process them, a view or document may not be.

Well, which paint tools do you need to know about ? Painting always occurs in OnEraseBackground, OnPaint, OnDraw, or OnPrepareDC, and I'd suggest all the different tools, such as ExtFloodFill, Polygon, etc. are stuff you can learn one by one as you need them.

As an example, once you know that OnPaint is where a dialog is drawn, why can't you create a vanilla dialog app, override OnPaint and experiment, even though you have no idea how the framework gets to the point of processing that message ?

First of all I would still use std iostreams to read the file, and then I would read it in and store it in a vector. The only bit you need to learn then is how to display it, and the right place for that is OnPaint, using the TextOut function.
Is there a CEditView ? A CView will be fine for starters, then you should try it with a scroll view to see how scrolling is implimented.

You brought up something very important. You brought up the issue of not having to use CFILE and serialize. I thought all data read from and written to a file must be "serialized."
How can I read a file using using CFILE?
I agree TextOut is the way to go too.

I only vaguely know, because iostream is not broken, and I prefer to use the standard library. I believe the mechanism is very similar.

No, Prosise would present that only because it's part of MFC, but all the standard library is still there at your disposal.

I would suggest reading up on the SDK API...without a firm understanding of they work, it'll be really hard to pick MFC. It took me about 3 years to consider using MFC and actually try it, before that it was a failed attempt at OWL. SDK is easy to follow...top to bottom...like a DOS program with messages. MFC hides so much crap from you, but once you understand it, app development is sooo much faster. Considering you don't get stuck on goofy problems.
I've only been dickin around in MFC for about 1 year and a bit and I can accomplish anything I would want probably not the best MFC way!!! but when it's compiled it all looks and acts the same. Yup...definetly understand SDK then migrate into MFC, but it sounds like you've already started with MFC so maybe try and intergrate the two togather.

Do you really think so ? To me, having done it in reverse, that's like learning C before C++, doing it the hard way before the easy way.

I think the advantage to learning the WIN32 APIs through raw SDK programming is that you learn the purpose of each of the functions, messages and other pieces that make up a Windows application.
With that said, MFC and WTL are structured around the SDK in an object-oriented way and are surely a superior way to develop Windows applications, but by knowing and thouroughly understanding the SDK, it can be understood what these two frameworks are trying to accomplish. Then when you want to try to implement something that the original designers of MFC and WTL had not anticipated, you can tackle the problem with your base knowledge.
While I agree that SDK programming is the harder way to develop a Windows application, I think that the comparison of "C : C++ is like SDK : MFC" falls apart because going from C to object-oriented programming in C++ is a completely new way of thinking. MFC is simply an object-oriented wrapper around concepts and restraints that are created in the SDK. This is just my opinion though.

You're right, of course, but the example is there, in both cases people suggest the harder alternative should be learned first.

I made the initial transition from VB to Borland C++...OWL was chinese to me...I picked up the C++ lanuage constructs(??) quick cuz they're the same in most langs...the OWL really through me off though...The createWindow functions compared to VB's click and drag were very foriegn to me.
I later bought (without really knowning what it was) Win 95 programming API bible, which was much easier to follow. The code samples taugh me all the in and outs of windows programming. Once I understood what the CreateWindow function actually did...and the parameters actually meant...MFC was much easier to learn then when I tried OWL withouth knowledge of the API...
Everybody's different though...I don't imagine my experience in VB helped, cuz it really only made me think....god...programming is easy...which...is a totally different story in C++.

Don't worry, this is not a problem only with you. This is the same problem every newbie of MFC/VC++ encounters. And among many reasons of the popularity of JAVA this is also the one. There is absolutely no fault of the writers of books you named above. The main reason is the complexity of MFC and the absence of CodeDOM in VC++.

I mean that complexities involve in MFC and its HUGE learning curve are also some reason that many people looks towards JAVA. (Personally i dislike JAVA as I am a proud CPian). But if you ask one group of students to learn JAVA and other to learn MFC. Then after 6/7 months you give them a mini project. The group of people that learn Java will make this project much more quicker and easily than the people who are learning VC++.

This is not a fair comparison. java is a programming language. MFC is a class library. Tell them to study java and c++, one for each group. or actually tell them all to study both. The ones who dont get good at C++ in 6 months would be bad anyway, so let them learn java
Let the others then start with MFC or ATL or whatever

Thanks guys.
Christian Graus made a good point. He said, "C++ is a well designed language that is made to be non-restrictive, to leave the design to the programmer. MFC is a framework in which you need to do things the MFC way."
Is API programming *similar* to C++? I thinking the best way for me to learn windows programming is to approach it from *low-level*. In other words, I think I would master it if I can just start coding everything from scratch instead of using classes from MFC. I believe one reason I cannot understand all MFC classes and functions is because I do not know what *they actually do* and how. I am used to designing and implementing my own classes. I prefer to design my own classes for later use, like a personal C++ library. With MFC, I have to not only learn a huge framework of classes, but I have to follow a rule that the design have set. That is very limiting. I do not have problems with the framework. It is the vast number of classes in MFC that makes it difficult for me to see everything that is going on.
For example, I know class X handles a specific job. I can tell instantiate an object X or override class X, but I lack the knowledge of how things surrounding class X relate to it. Moreover, I do not know class X well enough to see its potential.
Kuphryn
P.S. I think I have to change track because I just cannot produce anything with MFC right now. Something has gone very wrong during the last two months of my studying from Prosise's. Part III of his book is about discusses topics beyond basics. So according to his agenda, I should be able to produce result by now.
So that leaves two choice: Jones' or API.
I will most likely try Jones' first. If that too leads me nowhere, then API will it is.

Have a look at http://www.codeproject.com/wtl/
I found it easier to learn WTL than MFC first. With MFC I found it hard to get the bigger picture with all the wizards and generated code. WTL is smaller and simpler. I plan to learn MFC 7 though. Note I've only written some simple windows apps.

I looked at the API code at http://www.winprog.org/tutorial/ and I understood it easily. It looked just like the kind of C++ programming style that I use with my Win32 console programs.
This is weird. MFC code confuses me. There are too many intantiations and function calls. However, I have no idea what those objects and functions do.
I hear Petzold's API is the best. However, it is in C. What is the best *beginnger* API that emphasizes C++?
Thanks,

I love C++. I love windows programming, but I just cannot get to a point where I feel confident solving problems and be able to implement the program as windows based.
I will still have hope of working with MFC. I believe I need to start from the beginner of MFC as when I was learning C++ (cout >> "Hello World." Again, MFC will not get any easier. My plan not rely on MFC become easier. Rather, I plan to be ready for MFC.
I decided to buy Richard Jones' introduction to MFC. I know Prosise
s book is the best. However, that does not mean it is the only way to learn MFC. For example, I believe Deitel&Deitel's C++ How to Program is the best book for learning C++. However, it was not the first book I read. By the time I read it, I was able to gain so many insights "advices" that they give because I understood the fundmentals of C++.
I will apply the same learning approach to MFC. I really should learn API first, but I feel MFC is very learnable. It is just that MFC is huge, and so I have trouble focusing and learning everything at once. For example, looking about at C++, I am impress with myself knowing C++ is itself huge. I learned C++ in two months.
