Ok.
I need help here.
This is what i done:

#include <atlbase.h>
extern CComModule _Module;
#include <atlcom.h>
class ShellWin: public IDispEventImpl<WHAT_I_NEED_TO_PUT_HERE>
{

void Connect()
{
    CoInitialize(NULL);
    static SHDocVw::IShellWindowsPtr m_spSHWinds;
    if(m_spSHWinds.CreateInstance(__uuidof(SHDocVw::ShellWindows))
        == S_OK)
    {
        // Event Sink
        //
        LPCONNECTIONPOINTCONTAINER pConnPtCont;

        if ((m_spSHWinds != NULL) &&
            SUCCEEDED(m_spSHWinds->QueryInterface(IID_IConnectionPointContainer,
            (LPVOID*)&pConnPtCont)))
        {

            LPCONNECTIONPOINT pConnPt = NULL;
            DWORD dwCookie = 0;

            if (SUCCEEDED(pConnPtCont->FindConnectionPoint(
                __uuidof(SHDocVw::DShellWindowsEvents), &pConnPt)))
            {

                pConnPt->Advise( this->GetIDispatch(FALSE), &dwCookie);
                pConnPt->Release();
            }

            pConnPtCont->Release();
        }
    }
}
};

In my DllMain, i will do:
ShellWin o = new ShellWin()
o.Connect()

Now:
1)Remember, the project is not ATL project but a simple dynamic Dll
2)Does what i did make any sense (i took code from different sources)?
3)What i need to write here:
class ShellWin: public IDispEventImpl<WHAT_I_NEED_TO_PUT_HERE>
instead of the WHAT_I_NEED_TO_PUT_HERE
4)How can now i get the WindowRegistered event?

Please help me since i am lost here.

Consider posting in the shell group:

On the C++ side you'd likely want to base your project on
ATL. The ATL group is:

microsoft.public.vc.atl

As far as handling events, ATL offers IDispEvent[Simple]Impl
for dispinterfaces. For regular COM interfaces you simply
implement an object derived from CComObjectRootEx<>
and the event COM interface for your sink. Then you instantiate
it via CComObject:

CComObject<CSink>* pSink = NULL;
HRESULT hr = CComObject<CSink>::CreateInstance(&pSink);
// Init you sink here if necessary
DWORD dwCookie = 0;
hr = AtlAdvise(pSource, pSink->GetUnknown(), IID_IEvent, &dwCookie);
pSink = NULL; // Time to forget about the C++ object
....
AtlUnadvise(pSource, IID_IEvent, dwCookie);

Hi.
That code that i wrote is in vb6.
I need it in c++6 - not .net, you know just a simple c++
(if possible)
#include <windows.h>
...
...

in vb there is the magic word WithEvents, i do not know how to do that in
c++.
I want to get the events i wrote:

Private Sub winShell_WindowRevoked(ByVal lCookie As Long)
'callback function that gets winShell events - this function should be
called evrytim a shell windows was closed
End Sub

Private Sub winShell_WindowRegistered(ByVal lCookie As Long)
callback function that gets winShell events
'callback function that gets winShell events - this function should be
called evrytim a shell windows was created
End Sub

Lets start with the first class, i need a code that i can put in a dll
(not
mfc not atl not com) that as in VB, will callback the functions:
WindowRegistered WindowRevoked when these events are thrown.

I could not find any code that does it without MFC or COM.

As said, there should be a class, lets call it CShellWin
1)This class should have a member:
Private WithEvents oWinShell As SHDocVw.ShellWindows
2)This class should have a function f() that will do what i wrote in the
first post.
3)This class should have two callback functions:
WindowRegistered WindowRevoked
that will catch oWinShell events.

Does that helps?

Thanks for trying to help me.

Can someone please convert this code for me to c++

Which VB? VB6?

Which C++? You said not MFC. Do you want ATL, .NET, or what?
