Is this a quiz? Why don't you first tell us what problem you are having.

Where? The term "crash" rarely means anything useful.

Have you tried:
class A
{
public:
A() {}
A(const string& s) {}
string f()
{
return "hello world";
}
};
class B : public A
{
private:
string s;
public:
B()
{
s = f();
}
};

Thank you David!!

so can you please explain me where I was wrong ?

In class A, does it still crash if you make the f() method static? You are using A's method before A is ctor'ed. It looks like it shouldn't matter, but who knows, maybe some static consts are not available until after the first inst of the class is created? Sounds doubtful, doesn't it.

Thanks NealAB,
Yeah I got your point!
I think that is only happening. I was trying to use A's method before it was created.
Thanks again...

c_str() is a method of the basic_string class.

This indicate that,Text is member of EditBox(its datatype) and c_str is member of Text(its data type), and obvioulsly, you could find out that.

Hi there,
I'm unfamiliar with C++. Onli done VB before.
If I'm trying to create a form that has an embedded media player(any version) in C++, Should i use MFC or MS .NET form for C++? Is there an specific purpose for each usage? i.e MFC/C++?
And do i require media player SDK in the project?
Please advise. Thanks.
Your expertise is appreciated.
Regards,
Brendon

You should be able to drop the WMP ActiveX control onto the dialog template like any other control.

I have read about the Intel Threading Building Blocks vs. Windows threads.

Personally I am concerned about using vendor-specific codes. It could mean lots of work for later on reengineering the code to fit an AMD processor. Just curious about whether there is anyone really using TBB? Would you mind sharing your precious experience with us?
Thanks!

suppose we are having three exes which contains a package to be installed(each exe). how to run this one after the other ie after the complete installation of one exe the other should start
Arise Awake Stop Not Till ur Goal is Reached.

Use the CreateProcess()/WaitForSingleObject() pair.

Hi guys
I was wandering where I have to put this...
-----------------------------------------------------------------------
int ret=AfxMessageBox("You will exit the program.\nContinue?",MB_YESNO);
if (ret==IDNO) return ;
(someone more is needed ?)
-----------------------------------------------------------------------
...in my SDI application when someone clicks on the right upper Cross (standard close button) of my app.
Thanks in forwarding.

Have you considered handling the WM_DESTROY message? This will handle all methods of your app closing ("X", Alt+F4, File/Exit).

In my CFormView? In my App?
I've tried in my CFormView but the app is closing anyway.
I miss something to do?

Yes.

Are you still calling the base-class implementation. What does the OnDestroy() method look like?

How about in response to WM_SYSCOMMAND where wParam==SC_CLOSE?
This should be done in the app main window, wherever that is.

Override the WM_CLOSE message (OnClose) in your MainFrame class, and put your code it there. It will catch the X in the uppoer right corner, as well as Alt-F4, or an attempt to close from the task manager.
Hope that helps.

It helps a lot, that works fine, thanks.

The recommended place for a close confirmation is in an overload of CanCloseFrame() in your CDocument-derived class.

This is the place, thanks.
