Beginning MFC (Prosise) Part III - Now What? :: C++
-
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, Kuphryn

Mainframe and documents can only handle command/UI messages. I cannot decide where to map command/UI mainframe, view, or documents. 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. kuphryn wrote: The last issue I am not certain of is all the painting tools.

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. kuphryn wrote: Yes, I read everything very carefully.

Thanks! 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. Kuphryn

I believe the mechanism is very similar. kuphryn wrote: I thought all data read from and written to a file must be "serialized." No, Prosise would present that only because it's part of MFC, but all the standard library is still there at your disposal.

Hi. I began study MFC programming from Prosise two months ago. I finished the first two part of the book and will begin Part III. To be honest, I still cannot design a program of *my own* and implement it using MFC. I read reviews about MFC books including Prosise, Jones, and Deitel. I see again and again that one of the most difficult part of teaching MFC is to *not* discuss AppWizard and ClassWizard. Prosise does it by chapter 4. Nonetheless, Prosise's book is an ideal MFC *reference*. Anyways, I learned quite a bit from reading the first two part. I really appreciate the document/view architecture. I want to start implementing my win32 console programs into MFC so bad. I can just *feel* it, but I cannot get it done. There are many missing pieces in this puzzle. I can picture the final results, but there are so many missing pieces (how?, why?, what?, when?). I have no idea how to gather all the missing pieces. I first began programming (ever) as well as programming using C++ last fall semester. C++ caught my interest quick. Learning MFC, for some reason, is not the same. I cannot apply the same formula of *diving in*, which was how I became so proficient with C++ in both design and implementation. I can solve most problems using C++ (except for big projects). One reason, I think, is because there are *too many tools* in MFC. I can say I have seen close to just about everything there is to see in C++. I tried again and again to get apply the same strategy to MFC, but it does not seem to work. So here I am, beginning Part III from Prosise's book and howing no is lost. What are my options? I can considering Jones' Introduction to MFC Programming with Visual C++. If nothing else works, I will most likely go a different direction (Jones) and then return to Promise. Kuphryn

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++. Imran Farooqui

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.

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 Nish It's seven o'clock On the dot I'm in my drop top Cruisin' the streets - Oh yeah I got a real pretty, pretty little thing that's waiting for me

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++.

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. Kuphryn

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, Kuphryn
