mfc, ActiveX Events / Messages

1. activex in activex event handling - CSharp/C#

2. Activex control events not firing or ActiveX composite control not listening

I'm new to ATL so please bear with me.

I'm using VS2005. I generated a composite ActiveX control to host
ActiveX controls. It will host two or more ActiveX controls. I put the
ActiveX controls on the dialog at design time. I've also put a few
standard buttons.

Here's a clip of the generated class def:
class ATL_NO_VTABLE CTest5Ctrl :
    ....
    public CComCompositeControl<CTest5Ctrl>,
    public IDispEventImpl<IDC_MMHITIMERX1,CTest5Ctrl>,
    public IDispEventImpl<IDC_MMWAVERECORDERX1,CTest5Ctrl>
{...}

I used GetDlgItem() and AtlAxGetControl() to get smart pointers around
the ActiveX controls. I used CAxWindow.Attach() and GetDlgItem() to get
wrappers around the buttons. I did all of this in OnInitDialog -- (side
question: should I be doing this in OnInPlaceActivate?). This, I'm
guessing, doesn't really pertain to my problem, but I put it out there.

I added event handlers for the buttons which then call some methods on
the ActiveX controls. For ex:

LRESULT CTest5Ctrl::OnBnClickedBtnRecord(WORD /*wNotifyCode*/, WORD
/*wID*/, HWND /*hWndCtl*/, BOOL& bHandled)
{
    HRESULT r = m_spWaveRecorder->Recording();  // ActiveX control
    bHandled = TRUE;
    return 0;
}

Calling Recording() should fire a OnStart event. I added an OnStart
handler. Here's the generated sink map entry and my handler.

BEGIN_SINK_MAP(CTest5Ctrl)
    SINK_ENTRY(IDC_MMWAVERECORDERX1, 1, OnStartMmwaverecorderx1)
END_SINK_MAP()

void __stdcall CTest5Ctrl::OnStartMmwaverecorderx1()
{
    // I should get here
}

Now I get the button events. I can step into them and call methods on
the ActiveX controls. I put breakpoints in all of my ActiveX control
event handlers and none of them are entered. I put breakpoints in
BEGIN_SINK_MAP and they are entered upon startup.

I tried Spy++ and I don't see events being fired from the controls but
being new to ATL and Spy++, I don't know if what I'm seeing is normal
or not. I see other events such as mouse movements and clicks, but
nothing unique to the controls.

I have no idea why I'm not getting events from the ActiveX controls.
Any ideas?

3. Getting activex control event from ActiveX control.

4. WM_HELP message and ActiveX control

5. Windows message flow from container to Activex control

6. Activex control containment message reflection

Is there a way to get ATL ActiveX control containment to reflect
specific messages to the ActiveX control itself?

My problem is that when I send WM_SETTEXT and WM_GETTEXT message to the
AtlAxWinLic80 window I would like it to reflect the message to the
ActiveX control itself. Is there a way to do that?

7. Processing ActiveX-Window-Messages In The Client

8. Message Handling in ActiveX Control

I have developed a new ATL COM object.I have added a WM_LBUTTONDOWN
handler to the control. The WM_LBUTTONDOWN is not firing continuously
when the Mouse Leftbutton is pressed down. I would like to know what
is happening.
