Maybe you should add a label control (CStatic) near your progress bar, and set its text programmatically? Something like this:

CString s;
s.Format(_T("%i%%"), m_cMyProgressBar.GetPos());
m_cMyLabel.SetWindowText(s);

I hope this helps.

first of all, i told you to EDIT the existing post, to resposting again and again a huge bloc of code.

moreover, why i told you to use it? because Chris asks us to[^] (see 5.)! the code samples should be embraced by pre tags.

at last, it DOES PRESERVE the formating, but you used it wrongly.
if you want to see the empty lines, place at least a space on those lines.
and if you want to see some indentation, just put some spaces at the beginning ot your lines, and you'll see the spaces that doesn't appear in normal case...

oh, i was forgetting : when you put some #include statement, use the < and > html codes to print < >, otherwise, your include headers will be understood as html tags too.

But, before this gets more out of shape. I agree what you said was completly valid as far as the response protocols I employed is concerned (That won't happen again) but the way you said it did not inspire me to seek to thoroughly correct myself.

Sorry if I pressed your buttons though.

Again, this is false. This statement is true only if the function is pure virtual. You can perfectly have a virtual function in the base class which is not implemented in one or several derived classes (even not implemented at all in the derived classes).

I think you should try this:

    {
        A::f(a, 1);
    }
};

won't compile more. A::f() is virtual, so, not implemented...

moreover, the compilation error is no B::f() implementation overloads A::f()

You can perfectly have a virtual function that is implemented in the base class. Making it virtual doesn't mean that you cannot implement it. I think you mix it with a pure virtual function which is:

virtual void f() = 0;

The proposed solution solves the compilation error message mentioned in the original post: "error C2660: 'B::f()' : function does not take 2 arguments". In my opinion, just adding an implementation for A::f() is not a solution for original problem. Missing implementation (if really was not done by the author) will be reported on linking phase.
