hi everyone,

I used the MCI controls to play the video files... I can able to play *.vob *.dat *.mpg files but the problem i was facing is that I am NOT able to play mpeg 2 files with m2p extensions .... Can anyone tell me whether MCI supports m2p format files?

Thanks in advance

With regards

If you set lpstrDeviceType to

 <br />
MCI_DGV_OPEN_PARMS mciOpen;<br />
mciOpen.lpstrDeviceType ="MPEGVIDEO2";

what happens?

First of all I like to thank you for replying for my message . I dont know where to use your code

MCI_DGV_OPEN_PARMS mciOpen;
mciOpen.lpstrDeviceType ="MPEGVIDEO2";

Can you help me with this...

I traced the application and found out that i am getting the error while calling this function MCIWndCreate(.....)

Code Sample ::::::::::::::::::::
HWND CSampleMCI::Initialize()
{
if((c_Player=MCIWndCreate(hwndParent,AfxGetInstanceHandle(),

WS_CHILD | WS_VISIBLE | MCIWNDF_NOTIFYALL | MCIWNDF_NOAUTOSIZEWINDOW
|MCIWNDF_NOAUTOSIZEMOVIE|MCIWNDF_NOTIFYERROR|MCIWNDF_SHOWALL
, m_sPath))==0)
MessageBox("Error in initialise");
MCIWndSetTimeFormat(c_Player,"ms");
MCIWndSetActiveTimer(c_Player,100);
lVolume=GetVolume();
return c_Player;
}

Thank you very much
Awaiting for your reply...

Thank you one again for replying

hmmm Its giving the same error message (The error message is "The Specified file cannot be played in the specified MCI device. The file may be corrupt, not in correct format or no file name")... I found out one thing that your code had suceeded without error by checking the return value(as given below) ... and also I created a registry value( in regedit) for MPEGVIDEO2 in MCI32 key folder and set the value as MCIQTZ32.DLL is that OK??? .... for MPEGVIDEO I have the key already(so mpeg 1 is playing fine with MCIFMP32.DLL in registry) but for the MPEGVIDEO2 I created new one .... If I didnt create this key, your code returns some error message as their is no DLL linked with MPEGVIDEO2 Devicetype

I had included your code in my btnPlay() function in the main dialog is that OK ???

The code snippet for the button play is as follows

void CSeamlessPlayerDlg::OnBtnPlay()
{
if(index == m_PlyLst.GetItemCount())
index=0;
char lpszErr[256];
CString SPath=m_PlyLst.GetItemText(index,2);
char lpPath[256];
strcpy(lpPath, SPath);
///////////////////////////////////////////////////////////////////////////////////
MCI_DGV_OPEN_PARMS mciOpen;

mciOpen.hWndParent = m_hWnd;
mciOpen.lpstrElementName = lpPath ;
mciOpen.lpstrDeviceType ="MPEGVIDEO2";
mciOpen.lpstrAlias ="MPEGVIDEO2";

MCIERROR err = mciSendCommand( 0,MCI_OPEN, (DWORD)(MCI_OPEN_ELEMENT|MCI_OPEN_TYPE
|MCI_DGV_OPEN_PARENT|MCI_DGV_OPEN_WS),(DWORD)(LPVOID)&mciOpen);

if(err != 0)
{
mciGetErrorString(err, lpszErr,256);
MessageBox(lpszErr); // display error if failed
}

////////////////////////////////////////////////////////////////////////////////////
if(m_PlyLst.GetItemCount() != 0)
{
// mci.Stop();
mci.SetPath(SPath);
mci.SetParent(m_video.GetSafeHwnd());
mci.Initialize();

// mci.SetParent(m_video.GetSafeHwnd());

// if(i==m_PlyLst.GetItemCount())
// mci.Initialize();

::ShowWindow(mci.GetWindowHandle(),SW_MAXIMIZE);

mci.Play();
SetTimer(1,1000,NULL);
}
else
{
MessageBox("Check your Play List");
}
}

Thank you,

Awaiting for your reply Smile | :)

I think you are new on MCI for example if you need to a HWND handle you can see MCI_DGV_STATUS_HWND (MCI_STATUS)
if I guess is true see examples on codeprojext about MCI but for play you can use of

<br />
MCI_DGV_PLAY_PARMS	mciPlay;<br />
mciPlay.dwFrom = mciPlay.dwTo = 0;<br />
mciPlay.dwCallback = MAKELONG(hWnd,0);<br />
mciSendCommand(/*its return of openmci that you need to get it*/DeviceID, MCI_PLAY,MCI_NOTIFY,(DWORD)&mciPlay);<br />

1) speak proper english so that everybody can understand you
2) post the code (into <pre></pre> html tags)
3) ask a specific question

You don't know where to start ? ask a good friend

Hi.

Yes I tried using CListCtrl but it is not showing an image in the List Control.

Here is the sequence how I proceed.
1. Add List Control on the Dialog box.
2. CMyDlg:: OnInitDialog()
{
Get List Control pointer in pListCtrl by using GetDlgItem(ID_OF_LIST_CTRL)
if( NULL == pListCtrl->GetSafeHwnd() )
return;
CImageList *pImgList = new CImageList;

pImgList->Create(IDB_IMAGE1,50,0,RGB(255,0,255));

pListCtrl->SetImageList(pImgList,LVSIL_NORMAL);

LVITEM lItem;
lItem.mask = LVIF_IMAGE;
lItem.iItem = 0;
lItem.pszText = "HI";
lItem.iImage = 0;

pListCtrl->InsertItem(&lItem);

}

Still I could not see an Image in the List control.
Am I missing something here?

Help Please.

Thanks

I think you forgot this line m_pImageList->Add(Bmp,RGB(100,105,0));
CBitmap *Bmp;
m_pImageList->Add(Bmp,RGB(100,105,0));
m_List1.SetImageList(m_pImageList, LVSIL_NORMAL);

Sir,

int a = 1;
for(int i = 0; i <=10 ; i++)
a = a + a++;
There is no problem in understanding the above written loop

I have some problem in the following code.Please explain it.

for(int i = 0 ; i <= 10 ; i++)
a = a + ++a;
Please explain the working .I mean how it works.

Thanks

lets take it step by step, let a=1 initially:

1. i=0
2. a=a+ ++a;
Because the ++ is a prefix, the increment is done before evaluating the expression
here: a = 1 + ++a
=1 + (a=a+1);
=1+ (a=1+1);
=1+ (1+1);
=3

etc.

hope this helps.

That is not correct, since the prefix operator
changes the value of a before the expression being evaluated,
hence (with a=1 initially) you will have

a = 2 + 2;
=4

at first iteration. I tested it.
