Hi Jean-Francois,
Thanks for your reply and inputs. I really appreciate it. Here're things I
have implemented:
1. I am using "NM_INIT_BACKGROUND" when I initalize the conference manager.
I have also tried "NM_INIT_CONTROL" and they behave the same on this issue.
2. I create two ActiveX windows with "PreviewNoPause" and "RemoteNoPause"
types respectively when I start Netmeeting in my application.
3. When I close Netmeeting in my application, I destroy two ActiveX windows
first and I do release all the COM interfaces/sinks as below:
HRESULT Conf::Uninitialize()
{
// Was in ~Conf () before
m_pMgrNotify->Disconnect();
m_pMgrNotify->Release();
m_pMgrNotify = NULL;
m_pCallNotify->Release();
m_pCallNotify = NULL;
m_pConfNotify->Release();
m_pConfNotify = NULL;
if (m_pINmCall)
{
m_pINmCall->Release();
m_pINmCall = NULL;
}
if (m_pINmConf)
{
m_pINmConf->Release();
m_pINmConf = NULL;
}
if (m_pINmMgr)
{
m_pINmMgr->Release();
m_pINmMgr = NULL;
}
return S_OK;
}
Here're things I have found:
1. If I start Netmeeting in my application and close Netmeeting without
making any calls, I can see the little NM Icon in the system tool bar gone
right away when m_pINmMgr->Release() is executed.
2. If I start Netmeeting in my application, make a call to someone, hang up
the call and close Netmeeting, the little NM Icon still stays there no
matter how long I wait after m_pINmMgr->Release() got executed.
This little NM icon is gone only after I destroy my main window which is the
parent window of those two NM ActiveX windows. If this is a FEATURE of NM3.0
SDK, we might have problem integrating other video apllications(i.e., video
mail, H.324 phone) with NM into one single application.
Other NM3.0 SDK question:
Does anyone know how to start/stop video when not in a call or conference?
As I know the pVidChannel->SetProperty(NM_VIDPROP_PAUSE, TRUE/FALSE) method
can only be used when you are in a conference and a video channel is added
to that active conference.
Best Regards,
Mike
