int the C code the problem is in the m(c); function
but i don't know what's wrong

Hello,
I am new in VS.Net and i have some knowledge about C#.Net. Now i want to learn VC++.Net by self study, so if any one tell me some free resource and startkit or any web which give trainning from start.
Thanks and regards,

Hi
I thinck it is not the time to start VC++,It seem Microsoft does not need (&want) C++ programmers any more, I tring to forget VC++ ,but I ...
shame on Microsoft.

1. Standards conformance
2. new MFC
3. What do you think C# and VB.NET are written in ?
4. New Managed C++, if you want it.

Is this just your opinion, or do you have some factual data to back this claim up with?

No direct factual data, But answer this Question what microsoft do for C++ programmers in .Net?

Let me say my opinion and ask for more information from the experts here in CP:
VC++ will not die, because there is not any better language (yet) even in .net to do quick jobs with large amount of calculations. (And I don't think producer (probably a company) of a very expensive hardware decides to write drivers and app's with C#! while C# is sometimes 10 times slower, in some very special occasions, it's not good for this type of programming. (it even does not support Double!!!!))
But what about cross platform applications? What about commercial applications? I think they'll select a technology with which get to an application more quickly! Quality and Performance are not the first issue. In this case VC++ might be really obsolete!
Take a look at WinFX in Microsoft, please. What do you see? System.web, System.windows, System.Windows.Forms, System.Net, System.security (PF=Avalon, CF=indigo); Vista is going to offer a lot of new things to developers of .net. And Which one has the real focus in .net? Managed C++ (even without a visual editor!), C++/CLI, MFC, VB .net or just C #??!!
I believe C#.
Thinking a bit more. Next generation of programs. Parallel programming. Will that be easier to do this on machines which are OS independent (I've heared that .net platform and it's CLR is moving towards Linux, Mac OSX, so and so.) or doing it with VC++? So Microsoft might continue support of .Net, but frankly, I didn't see any thing good for C++ programmers at least before VS .net 2005, which I didn't see that yet!, in .net. For a C++ programmer ,however C++/CLI I think is the best choice, but I don't see any support in MFC for .Net, some one here said there is could you describe it more please, I'm really interested. (I lost my ClassWizard because C# don't like it and I have to write in the same IDE!
I love C++ and I hope MFC will be updated to use .Net easier and turns C++ to the first language of .Net, but it's much like a mirage.
I'm from the other side of the world and my knowledge certainly is incomplete and full of gaps. It will be appreciated to hear from those who have more information and science. To correct me and give some of the light of their knowledge to brighten the life!
P.S. English is not my native language, so please don't blame me on that!

I don't know of any resource beyond this site. If you know C# syntax, I'd be inclined to download some code from code project, and just play with it. If you're looking for a beginner book, 'teach yourself C++ in 24 hours' is pretty good.

First of all, welcome to the most interesting part of your life! (Programming with C++);)
I believe much of it depends to yourself and the book or any other thing which will interest you. You may need to read more than one book!
I started with the fifth version of this book almost 2 years ago:
O'Reilly - Programming with Microsoft Visual C++ .NETI now about the sixth edition but perhaps there is a newer version available. (After CLI there must be)
You might search Amazon for that.

Imagine such a situation: you have a template data structure class, and you want to stream data from a file into your data structure. Values in the file should all be of the same primitive type, but the type itself is not recorded anywhere explicitly. And the question is: in the main program, how would you find out the type of values that a specific file stores? Because the type is needed to instantiate the data structure before you can start streaming data in...
If you guys want to understand the whole problem the link for the Project can be found at: http://www.cs.up.ac.za/download.php/COS212/Assignments/project1.pdf
or
http://www.cs.up.ac.za/download.php/COS212/Assignments/project1.ps
I've been struggling to find a sollution to this problem for weeks now. The project has to be in tomorrow.
Help would GREATLY be appreciated.
Thanks alot

As I understand, you have to use a template to create your tree, but you will manually select which type according to the input file.
for example, you will read int if the file contain int, double if te file contain double, ...
YourTreeStructure <int > yourIntTree;<br />
YourTreeStructure< double > yourDoubleTree;<br />

here's a sample line of codes
#1
CString strLine;
strLine = "Hello";
cout << strLine << endl;
output
007706BC
#2
CString strLine;
strLine = "Hello";
printf("%s\n", strLine);
output
Hello
Why didn't cout display the "Hello" string, but using printf will display the desired output. What's the difference between cout and printf that made the above discrepancy? Thanx

Try using String of char* instead of CString. Just remember to import <string> in your C++ file.
|
|
|
|
|
CString has the address of the memory location I think.
|
|
|
|
|
|
Use GetBuffer to the underlying char *, don't forget to call ReleaseBuffer after.

Thanx guys, Now I know what's the difference and what to do. But since it is a console app, i'll use printf instead.

This makes no sense at all. Both printf() and cout can be used for console applications.

yup, both cout and printf can be used in console applications but since cout had some trouble or need additional things to consider, I think it will be beneficial to use printf instead

cout had no trouble. It was doing exactly what it was told to do.

If you consider the lack of about nine characters to be beneficial, you've a great deal to learn. It would be beneficlal to learn how a CString object behaves when used with cout and printf(). You'll be amazed at what you find!
