Pick up Visual Studio and play around writing MFC apps. It will give you a nice into to classes, OO, UI design, and you can knock up some interesting apps.
I use MFC a lot writing test programs for my Windows drivers and is an excellent technology.

Good link!
I have been wandering around the net trying to find the answer. SO it seems it is a C only method of struct func pointer initialisation. Interesting.

Nah, doesnt work as C code with VS either.
error C2059: syntax error : '.'
And it is C code, I checked by declaring a variable after a func, it gulched at that, so it is deffinitely seeing it as C code.

Exactly: it still does not.

Cheers Chris, I thought that was the case.

So what is the specific VC compiler output?

ok i have a problem with MFC, i have two dialogs and an additional class, in first dialog i create an object of my custom class and set its values, now i want to pass my object to an other dialog to manipulate it, how can i do that?
|

|

Just rewrite the dialog contructor passing it a handle or pointer to your object.

im noob in this topic could you show me an example?

You can also chenge the information between your main application and a dialog modal in few ways, which you can see here[^], there you have some exmaples ...
|
|
|
|

Yesh, override the dialogs DoModal() func (ie just add a new constructor that takes the params you want.)
In your implementation of DoModal() you copy the params locally, and then call the base class DoModal().
When your other dialog or whatever creates your new dialog, it passes the required params to the DoModal() func.
MyNewDiaolog * dialog = new MyNewDialog;
dialog->DoModal(<add your="" params="" here="">);
==============================

It's usually not a good idea to tie the dialogs together like that. It makes them too interdependent. Consider keeping the data in the custom class (complete with getters and setters) and creating an instance of that class in the CWinApp-derived class. Each dialog can then get access to that single instance using AfxGetApp(). This is similar to what is happening when have a document (and a view). The data, shared by the entire app, is stored in the document. When you want to access that data, you ask the document for it.

Returning a pointer to the app class, allowing a dialog class to access data internal to the app class does what exactly in terms of following the Object Oriented methodology? 
A typical hack. That is why OO design allows for polymorphism, so that data can be passed around as required. Overriding the dialog constructor then is actually a purer OO way of acchieving what he wants.

could you please provide more information regarding your project... for what you want to use FaceBook information? for Authentication purpose or you want to use some other information in your project.

I want to use this for authentication purpose and later I want to add some friends into the community. My project is an application like skype.
Thanks!!

I just read an article which augues that coding with only one programming language would limit one's capability to code.
I'm a little confused about this argument, because I've always thought that, one developer proficiently mastering one language outperforms one using many language but he actually knows relatively little about each one.
So, I'm not sure whether the idea of the passage I read is very correct.
I just want to hear more opinions about this issue, so, please feel free to show your thoughts about it.

I suspect they're concerned about paradigms more than actual languages. If you know only imperative languages or only functional languages for instance you may have trouble solving problems that are better suited to the other paradigm. You may know several imperative languages, but you still may not easily solve problems suited to functional languages.

Thanks for your reply.
Actually, I feel C++ is quite limitless, because it contains three paradigms, which are process-oriented, object-oriented and generic.
So, I'm wondering if you could tell me more about other paradigms, do they exist? (I'm kind of a green hand~  )
