Superman,

That was it, I never defined it. The tutorial just showed

int add(int x, int y)

,
It never showed the rest. So when I put this in the add.h file:

int add(int x, int y)
{
return x + y;
}

It worked perfectly. I should of known better Frown | :-(

Thanks for helping out!

in general, you should avoid putting code in a .H file.

put this in the .C/.CPP:

int add(int x, int y)
{
return x + y;
}

and put this in the .H:

extern int add(int x, int y);

that extern says "there is a function which looks like this, but is implemented somewhere else". that will satisfy the compiler. the linker will take care of the rest.

the reason you don't want to put code in a .H file is that someday you might end up #including that .H into multiple .CPP files, and when you do that, you're going to get linker errors complaining about a multiply-defined symbol called "add".

think of what #include does: the C/C++ preprocessor literally inserts the text of the .H file into the place where you did the #include, before starting the compilation. so if you #include that .H file into multiple .CPPs, you will get multiple copies of the .H file contents. and if the .H file has a function, you'll get multiple copies of that function.

about the only time you'll do implementation in a .H file is if the function is a class member function.

Ohhh! Ok I understand. I haven't got far into the tutorials just yet but I figure on down they line they will talk about extern and more of the best practices. Thanks guys

Or you're doing a naked inline global function. And about the only time that happens (or should IMNSHO) in C++ programs are those places you need those pesky friend functions that there's just no way around.

You measure democracy by the freedom it gives its dissidents, not the freedom it gives its assimilated conformists.

Get IExplorerBrowser from a Windows Explorer (Vista)

Hi
I am developing a band for Windows Explorer and I want to get notified when the current folder changes. Looks like IExplorerBrowser provides the notifications I need, but I can't get that interface in my SetSite function. I can get IShellBrowser:

STDMETHODIMP CExplorerBand::SetSite( IUnknown* pUnkSite )
{
	if(pUnkSite)
	{
		CComQIPtr<IServiceProvider> pProvider=pUnkSite;

		CComPtr<IShellBrowser> pShellBrowser;
		if (pProvider)
			pProvider->QueryService(SID_SShellBrowser,IID_IShellBrowser,(void**)&pShellBrowser);
	}
	return S_OK;
}

But I don't know what to do to get IExplorerBrowser. I tried QueryInterface on pUnkSite and on pShellBrowser. I tried calling QueryService with IID_IExplorerBrowser and different service IDs. Nothing seems to work.

I'm starting to think that IExplorerBrowser is only intended to be used to host an explorer window in your own application because there are many examples how to create a new instance but not how to get an existing instance.

Any ideas?

Thanks
Ivo

I’d like to join them in one program. The Output should look like this:
Combination number 1

Number 3 occurs 6 times
Number 48 occurs 7 times
Number 0 occurs 8 times

Combination number 2
Number 5 occurs 6 times

Etc.

What kind of counter or what loops should I use to successfully combine these programs?

Right now you've got two separate main() functions. How about renaming each of those to something more appropriate, and then create a new main() function that calls each of them?

Why do you keep repeating this question? If you want to draw a butterfly then I would suggest you get some books and learn about graphics programming.
