Is there anything on the modeless dialog? I had an interactive service that displayed a tray icon without any problem. The service called the following

CreateEx (0, AfxRegisterWndClass (0), "", WS_POPUP, 0, 0, 10, 10, NULL, 0);

m_notifyIconData.cbSize           = sizeof (NOTIFYICONDATA);
m_notifyIconData.hWnd             = m_hWnd;
m_notifyIconData.uID              = 1;
m_notifyIconData.uFlags           = NIF_ICON | NIF_MESSAGE | NIF_TIP;
m_notifyIconData.uCallbackMessage = WM_APP;
m_notifyIconData.hIcon            = ::LoadIcon (AfxGetResourceHandle (),
                                                MAKEINTRESOURCE (IDI_ICONTRAY));
m_notifyIconData.uVersion         = NOTIFYICON_VERSION;
strcpy_s (m_notifyIconData.szTip, 64, "Service Name");

Shell_NotifyIcon (NIM_ADD, &m_notifyIconData);

where m_hWnd was returned by the CreateEx call.

The service regularly called a message pump on the m_hWnd

MSG msg;

while (PeekMessage (&msg, NULL, 0 ,0, PM_REMOVE))
{
    TranslateMessage (&msg);
    DispatchMessage (&msg);
}

The window procedure for the m_hWnd received WM_ messages so I could process a double click and the right-click.

NOTE - my responsiveness to answer any questions about this will be really bad this weekend since I have lots of time-consuming plans. Good luck

In addition to Judy's reply...

Have you checked all the relevant members of the NOTIFYICONDATA struct?

With a breapoint on the Shell_NotifyIcon() call, what are the values of the hWnd, hIcon, uID, and szTip members?

The struct values are:

hWnd = 0x001A0230
hIcon = 0x0001000b
uID = 107
szTip = "AutoFileHandler is running"

The window has a static control and a button on it. More tomorrow.

hmm... Are you doing this from a service or is it not working in a regular app?

I have it working in dialog app, but I need to get it working in my service app.

question to the pros: nasty ASSERTION in BOOST

Hy there!
i have a hughe problem in my company. i have a quite complex application (distributed, corba, mulithreaded, Boost, QT 3.3)
and after closing the program (int closeevent() pApp->exit())
the program closes but after ca 5 sec. there comes an ASSERTION

attached_thread_count == 0
in tss_hooks.cpp

the code in boost looks like that:

attached_threadcount == 0 in tss_hooks.cpp. the code there looks like this:

it is in on_process_exit()..

catch( ... )
{
boost::call_once(init_threadmon_mutex, once_init_threadmon_mutex);
boost::mutex::scoped_lock lock(*threadmon_mutex);

BOOST_ASSERT(attached_thread_count == 0);
return -1;

even with the help of some c++ gurus and DevPartnerStudio we could not find the problem.
actually it isnt that annoying because only at exit it happens. but we cant deliver it to the customer like that.

does enyone has an idea what to do against it, even a trick to just dont show the assertion?

unfortunately i cant make a release-version for different reasons.

ideas? suggestions??

thanx for any input!!

p.s. someone gave me the following input in an other board:

Anyway, the assertion comes from the thread_specific_ptr machinery. It means that something registered a thread-exit handler but it wasn't called. This might happen if, for example, you use a thread_specific_ptr from a thread that wasn't created with boost::threads.

The problem isn't the ASSERT but what thread is not terminated. It's the 1st priority to check which thread and what line in the thread is still busy when the exit signal has been fired.

And why does it enter the catch block?! What throws?

abort[^] should do the trick, but I would ask the question on a Boost mailing list to properly fix the problem.

avi file on Status bar

ptr_Electron7-Mar-08 3:18

I am trying to play a AVI file on status bar indicating the progress for the lengthy operation.
I am doing this in a button click event. it is working fine if no statements are there below the call and, if there are statements below the avi start.. the avi is not playing on status bar.
I tryed with thread, but of no use.

void TestPb::OnButton1()
{
CMainFrame* pFrame = (CMainFrame*)AfxGetMainWnd();
pFrame->StartAnimation( IDR_AVITEST ,1);

whie(1)//Say length process.... If i comment while(1) .. avi is playing on mainfram status bar
{}
}

you should move the portion of code playing the AVI in its own thread... and start the thread on the trigger of your choice.

Hi,

Its hard to give you advice without seeing what type of 'processing' you are doing. You should avoid drawing on a window from a separate thread if at all possible. You may be able to simply pump the message que and move the AVI-frame painting into OnPaint.

In the while loop you can probably add:

while(somecondition)
{
	MSG oMSG;
	while(::PeekMessage(&amp;oMSG, NULL, 0, 0, PM_NOREMOVE))
	{
		if(::GetMessage(&amp;oMSG, NULL, 0, 0))
		{
			::TranslateMessage(&amp;oMSG);
			::DispatchMessage(&amp;oMSG);
		}
		else
		{
			break;
		}
	}

	//Your processing code goes here
	//Hopefully the work is done in chunks and continues to the top of the loop.

}
pre>

This will allow the dialog to process WM_PAINT messages normally.

Thanks you very much, for your help, what I am trying to do is extrading 1000's of records from database. since it takes quite some time I want play the avi file on the status bar of main frame,
but the call will be made from the dialg. say on button click event we are extracting records form DB and need progress on the status bar, but does not work...

void TestPb::OnButton1()
{

thpbar=AfxBeginThread(thPrgbar,THREAD_PRIORITY_NORMAL,0,0,NULL);
//Get 1000's records from DB ..verytime consumming process...
}

UINT TestPb::thPrgbar( LPVOID pParam )
{
CMainFrame* pFrame = (CMainFrame*)AfxGetMainWnd();
pFrame->StartAnimation( IDR_AVITEST ,1);
return (1);
}

void CMainFrame::StartAnimation( UINT id, int nPane /*=1*/ )
{
StopAnimation();
m_pAnimate = new CStatusbarAnimate;
m_pAnimate->Create(id, nPane);
}

void CMainFrame::StopAnimation()
{
delete m_pAnimate;
m_pAnimate = NULL;
}

bool CMainFrame::IsAnimationActive()
{
return (m_pAnimate != NULL);
}

// needed to ensure original text not visible
void CMainFrame::OnUpdateAnimate(CCmdUI* pCmdUI)
{
pCmdUI->SetText(_T(""));
}

Perhaps you should move to a message based inter-thread communication. You can even pass the percentage of completion.

Try something like this:

#define WM_START_ANIMATION WM_USER + 0x8
#define WM_INC_PROGRESS WM_USER + 0x10

void TestPb::OnButton1() 
{
thpbar=AfxBeginThread(thPrgbar,THREAD_PRIORITY_NORMAL,0,0,NULL);
}


UINT TestPb::thPrgbar( LPVOID pParam )
{
CMainFrame* pFrame = (CMainFrame*)AfxGetMainWnd();

::PostMessage(pFrame->GetSafeHwnd(),WM_START_ANIMATION,IDR_AVITEST,1);

int iCount;
int iPosition =0;
//Get count(*) from SQL DB and save into iCount;

// for each record in DB
while(reading DB)
{
// get 1 record
int iPercent = iCount * (iPosition / 100.0);
::PostMessage(pFrame->GetSafeHwnd(),WM_INC_PROGRESS,(WPARAM)iPercent,0);
++iPosition;
}
//end if
return (1);
}

void CMainFrame::OnStartAnimation( WPARAM id, WPARAM nPane /*=1*/ )
{
StopAnimation();
m_pAnimate = new CStatusbarAnimate;
m_pAnimate->Create(id, nPane);

}

void CMainFrame::StopAnimation()
{
if(IsAnimationActive())
{
delete m_pAnimate;
m_pAnimate = NULL;
}
}

bool CMainFrame::IsAnimationActive()
{
return (m_pAnimate != NULL);
}

// needed to ensure original text not visible
void CMainFrame::OnUpdateAnimate(CCmdUI* pCmdUI)
{
pCmdUI->SetText(_T(""));
} 

Add the following to your CMainFrame

///////
// ADD INTO YOUR CMainFrame HEADER FILE:
///////

afx_msg LRESULT OnMyProgress(WPARAM wParam, LPARAM lParam);

//////////
// ADD INTO YOUR CMainFrame MESSAGE MAP
/////////
ON_MESSAGE(WM_INC_PROGRESS,OnMyProgress)
ON_MESSAGE(WM_START_ANIMATION,OnStartAnimation)


//////////
// ADD INTO YOUR CMainFrame CPP file
/////////
LRESULT void CMainFrame::OnMyProgress(WPARAM wParam, LPARAM lParam)
{
int iPercent = (int)wParam;

if(100 == iPercent && IsAnimationActive())
{
StopAnimation();
}
else
{
// Update visuals here perhaps to reflect percentage of completion
}

while (1); not only stops avi to play, but the complete UI on the GUI thread will stop working.

well, Yes true just i mentioned to as a length process
Thanks u
I want to paly the avi on the mainfram status bar and start some lenthly process, while still the avi is playing... pls advice
