Initially I want to paint a rectangular strip above the client area. Its not working.
This is what I have in ncpaint().

void CChildFrame::OnNcPaint()
{
// still want the menu to be drawn, so trigger default handler first
//Default();
CFrameWnd::OnNcPaint();
CRect rc, rcGrabberOnly;
this->GetWindowRect(&rc);
rcGrabberOnly.right = (rc.right);
rcGrabberOnly.top = (rc.top-20);
rcGrabberOnly.bottom = (rc.top);
rcGrabberOnly.left = (rc.left);
CWindowDC * pDC = new CWindowDC(this);
CBrush* pBrush = new CBrush(RGB(255, 0, 0));
pDC->SelectObject(pBrush);
pDC->Rectangle(&rcGrabberOnly); //rcGrabberOnly);

cr_frm = RGB(255, 0, 0);
pDC->FillSolidRect(&rcGrabberOnly, cr_frm);

delete pDC;
delete pBrush;
return;
}

The rectangle is not getting painted.

BOOL CChildFrame::PreCreateWindow(CREATESTRUCT& cs)
{
// TODO: Modify the Window class or styles here by modifying the CREATESTRUCT cs
if( !CMDIChildWnd::PreCreateWindow(cs) )
return FALSE;

//cs.style &= ~((LONG)FWS_ADDTOTITLE | WS_THICKFRAME | WS_MINIMIZE | WS_MAXIMIZE | WS_SYSMENU);
cs.style &= ~((LONG)FWS_ADDTOTITLE | WS_THICKFRAME | WS_CAPTION | WS_MINIMIZE | WS_MAXIMIZE);

cs.x = 100;
cs.y = 100;
cs.cx = 600;
cs.cy = 200;
return TRUE;
}

Thanks enhzflep,
I am handling it in the child window.
void CChildFrame::OnNcPaint()

class CChildFrame : public CMDIChildWnd

What I am not clear about is what exactly to do in WM_NCPAINT
Should I just paint a rectangle above the client area

this->GetWindowRect(&rc); //returns the full window including the frame
GetWindowRect(&windowBounds); //returns only the client area

Should I be handling ON_WM_PAINT as well? I am already handling the ON_WM_PAINT in the CView class.

While the slider control is not visible it is actually there and fully functional.
If I try to approximate its position (which is slightly below the player window) and try to scrub the video. The scrubbing happens fine.

The problem was the ScrollSizes were not set. My view class was derived from CSrollView.
I tried setting the scrollsizes in UpdateInit and it worked fine.
Thanks Jochen, you are very good. The swiftness with which you found the problem is inspiring.

Thanks Richard for your thought. I did debug it but am still looking for some hint. The problem text is right in the top and I have tried to provide relevant stack details and pieces of function executed by the stack. I will try to optimize it further to make it more readable.

Rakesh

Thanks Jochen for your thoughts. I dont know how to address this since this isworking fine release mode. Could you throw some more light on what I should do.

Hello Serkan Onat,
I did put this question in codeproject. It was suggested that I should try to put it in full screen only when it is playing. Wait for the play event and then put full screen. I did that and it worked.
Thanks for the suggestion.
Will try with IWMPPlayer2
Will try LibVLC as well.
Regards,
Rakesh

Thanks You so much.
Full screen mode worked.

Hello Serkan Onat,
I have been trying to get the media player to play in full screen. I get a runtime exception for hrFull )below in code) which says E_UNEXPECTED catastrophic failure. I see this when I put a break point other wise the code runs fine though it doesnt go to full screen. By right clicking on the running media player and selecting zoom full screen I am able to play in full screen.
My objective is to have a button clicking which should play full screen.

The code below is what I am using. This code is in InitDialog.

LPUNKNOWN pUnknown = m_MediaPlayer.GetControlUnknown();
//LPUNKNOWN pUnknown1 = m_MediaPlayer1.GetControlUnknown();


HRESULT hr = pUnknown->QueryInterface(__uuidof(IWMPPlayer), (void**)&m_pWMPPlayer);
//HRESULT hr1 = pUnknown1->QueryInterface(__uuidof(IWMPPlayer), (void**)&m_pWMPPlayer1);


if (SUCCEEDED(hr))
{
CComBSTR strMovie = _T("C:\\movie\\Hero 2004.mp4");
m_pWMPPlayer->put_URL(strMovie);


VARIANT_BOOL bSc = VARIANT_TRUE;
HRESULT hrFull;

hrFull = m_pWMPPlayer->put_fullScreen(bSc);

}

Look forward to your direction on what may be done for full screen.

Rakesh

Thanks,
I got the event.

Hello Serkan Onat,
I think I got the even handler list. When I right click on the media player control it gives me the option of adding the even handler. I will add from here and try and test it. It appears different from what you meant.

Rakesg

I do not see the events listed. Probably I am on a wrong understanding of what the dialog designer is. When you say dialog designer I do the following.
Resource View -> ProjectName.rc -> Dialog -> IDD_VIDEO_PLAYER(xxxxxxx)
I double click on it and I am presented with the dialog designer. It contains the windows media player active X control. I select it but I dont see any properties pane with event listed. What I see is the properties window in the bottom right which has items like "open state" "play state" "url" "windowless Video".
I have wrongly understood on what you mean by dialog designer.

Hello Serkan Onat,
I could implement what you said and got the player a play a clip.
I need to handle event from the media player and be able to play and stop from with in the code.
I have been trying to add a handler and be able to get handles to play and stop and other functionalities. I didnt work.
HRESULT hr1 = pUnknown->QueryInterface(&spConnectionContainer);
if (SUCCEEDED(hr))
{
hr = spConnectionContainer->FindConnectionPoint(__uuidof(IWMPEvents), &m_spConnectionPoint);
if (FAILED(hr))
{
// If not, try the _WMPOCXEvents interface, which uses IDispatch.
hr = spConnectionContainer->FindConnectionPoint(__uuidof(_WMPOCXEvents), &m_spConnectionPoint);
}
}

if (SUCCEEDED(hr))
{
hr = m_spConnectionPoint->Advise(this, &m_dwAdviseCookie);
}

The this in Advise doesnt compile.

Could you give some direction as to how to play, pause and stop from within the code Also create a handler where I could get the play, pause, stop and other media player control events.
Regards,
Rakesh

Hello Serkan Onat,
Thank You so much for the solution posted by you. I should be able to test it in the next few days and will update you on the results.
