Create a static int variable inside the class.
Increment it in the constructor and decrement it in the destructor.

First of all, you have forgotten to derive bc from ab here.

Secondly, change the signature of get from
hawk23reddy wrote: void get(ab* c)
to
hawk23reddy wrote: void get(ab** c)
and while calling get, pass address of b as argument.

Try this:
...
void get(ab* &c)
...
Research passing arguments to functions and especially passing arguments by reference.

I have a bitmap on a toolbar that opens up a dialog when clicked. I wanted to add a (Ctrl+E) shortcut as another option to open it, I did add this shortcut to it in its ID properties in the Resource project...But how come it doesn't work? Is there extra code thats need to have the shortcut come alive? Am I missing something?
Thanks

Are you referring to a keyboard accelerator?

Yes, just like Ctrl+p does the print and so on. I would like to attach Ctrl+E to a bitmap icon on my mainMenu Toolbar.

Check out LoadAccelerators() and related functions. You might just be able to add an accelerator resource to your project.

I have done this before without adding any code, just can't remember how...its nothing but adding a shortcut to an ID in other words.

A mnemonic, perhaps?

You were right the first time, I just needed to map in the Accelerator table.
I do have another simple question as I am not very familiar with MFC toolbars, How can I load up or insert an existing bitmap to the existing Main Application Tool Bar, because, I would like to add a bitmap there and I don't feel like editing and drawing it,while I can just download it from somewhere.
Thanks

Hey, Can you recommend me what C++ library or classes are available for sending email via SMTP in C++. I'm on Windows platform. I need a library which supports attachments and SSL connections. What are the options available. I'm not into implementing my own
Oh I forgot to mention I'm using Visual C++ 6

Yes, I found few but none met the requirement (SSL, Visual C++ 6).
