I did say I wanted multiple sub-object copies in my design.

Anyway.
So the conclusion is, this is not standard behavior, that I am asking for?

Well I didn't mean that g++ should conform to Visual Studio :).
I was just saying....

Grumpy, i worked a little to produce this minimalistic example, so to keep things simple. one thing I know for sure, is that I don't want B to be a virtual base class.

I'm not convinced that this...

Hmm, I see that in my original example writing C::f() instead of C::B::f() works, and the effect is the same.

But how do I invoke D::B::f() ? Now I want to call the implementation of f() in the B...

It's not the same, because i'm calling f() from a nonstatic function so I *have* and object.
And, the compiler should know which B::f() to call specifically because I wrote C::B::f(). So it should...

Hello all,

I have the following problem when trying to disambiguate the behaviour of a function in the most-derived class:


class B
{
public:
virtual void f() {}
};

There is. You need to keep a refence to the EventHandler object that you added to the Event and you unwire that object with the -= operator on the reference.

I had no idea where to put this question, but here goes:

Can I do something about flickering?? I use, in C#, a TextBox control with its associated Graphics object.

Hello.

Can someone tell me what is the procedure of un-wiring an event handler from an event (if there is such a thing)?

You wire a handler to an event with the syntax:

Thanks. I needed that.

A different namespace ...
So how do I do that? A namespace groups some functions together or some classes or what?

Hello.

I'm exporting some functions with idl. Is there a way I can define a function that has the same name as a previously defined function? For example, I want to expose a "sin" function. The...

Is nwindowproc() a non-static member function of some class?

nwindowproc() is not a member at all ... it's just there in the cpp ...

Post the code that calls nwindowproc().

Well, you caught...

I'm calling a non-static member function from a function declared as follows:

OK...

1)My question wasn't a DLL vs OCX but a generic class vs control class question (of course, depending on the answer I would then build a DLL or an OCX).

The question was: can a generic...

Hey.

1)Just declare the method as returning something else than void.
2)Well, there's a discussion here. But I'd probably just confuse you, so you better check the MSDN reference.

There are at...

I just started off in this kind of stuff, so I'm practically nowhere yet. I have several questions in mind, e.g.:

Oh my god, it works! I can't thank you enough.

By the way, how was I suppose to know?! This odl stuff is most badly documented.

That was good to know, but it doesn't solve the problem.

Thanks, you were helpful.

Sorry, the error is still with me.

So I guess I must necessarily use a temporary variable, huh?

I have a "f" function whose result type is A.
I have a "g" function that takes one parameter of type pointer-to-A.

I have to call the "g" function using the return value of "f", but I can't:
