Only if the source interface is a dispinterface. That's not
going to be the case with the shell though - IIRC the shell
does not use Automation. I'd say forgoing ATL is a minor
inconveniece in this isolated case. Of course coding COM
left and right in plain C++ vs using ATL would upgrade it
to a small but persistent pain... :) The big pains come from
coding IDispatch, as well as writing ActiveX Controls and
containers by hand.

I'm not familiar with the shell - that's why I advised you to
ask in the shell group. As for ATL - you don't need it to
implement connection points. Read chapter 4 of "Inside OLE"


You may not need it, but it's going to be tremendous pain without.

by Kraig Brockschmidt for a plain C++ example.

Hi.
I realy do not know ATL/COm

Can someone please write me a small example to work on.
Here is what i need:

#import <SHDocVw>
I have DllMain() function inside my dynamic dll.
Can someone please write me the code that will catch the

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?
