To play mp3, I use MCIWndPlay macro. I want to make the tune to be played repeatedly until user wants a stop. Does anyone know how to do it?

(I am bing daft here - I have not much knowledge of mm programming.)
I wanted to use mci functions but hit a rock, because I do not know how to retrieve device id, and the device id is required to send the commands. Can you shed some light or point me to relevent sites? I tried but could not find any example telling me how to get the id, i.e. what name should I use in
MCIDEVICEID mciGetDeviceID(
LPCTSTR lpszDevice
);
I think once I know how to retrive the device Id I should be able to cook. PS I looked at the system.ini file, as a few internet findings suggest, but found nothing under the [mci] section.

Assuming you know the name of the .mp3 file (I'm boldly assuming it's a file), you can simply do:
<code>
char szMp3File [MAX_PATH];
strcpy (szMp3File, "C:\\myFile.mp3");
VERIFY (::sndPlaySound (szMp3File, SND_LOOP | SND_ASYNC));
...
<code>
VERIFY (::sndPlaySound (NULL, 0));

I tried the sndPlaySound(...) and passed in a .mp3 file but the mp3 file did not get played. instead, a wav file was played. I guess it is because this func works only for wav file so a default sound was played rather than the mp3 specifed.
In fact before I use the mp3, I was playing a wav file instead, using the PlaySound(...), which is similar to this one you suggested. I thought I should move up the ladder a bit by tackling more advanced multimedia stuff, which means the application can be more flexible. This is the background info of how I got here...
Do u happed to know how to get device id? It is really nice to know.

Perhaps this[^] article will help? Btw, I use BASS[^] to play MP3 files. I've also heard good things about FMOD[^]. Good luck!

I haven't much read about its architecture. But Generally interfaces should be exposed, as it is COM based architecture. Look for interface of your interest and use it. It should have api's like sendmessenge.

1. You better go for custom message box, the code you can get it by google search.
2. Or if you use windows NT based operating systems, you can try to use French localized dlls.

Declare a data member for your dialog:
NOTIFYICONDATA nid;
Then
<br />
ZeroMemory(&nid,sizeof(nid));<br />
nid.cbSize = sizeof(NOTIFYICONDATA);<br />
nid.hWnd = m_hWnd;<br />
nid.uID = 0;<br />
nid.uFlags = NIF_ICON | NIF_TIP;<br />
nid.uCallbackMessage = 0;<br />
nid.hIcon = LoadIcon(AfxGetInstanceHandle(),MAKEINTRESOURCE(IDI_....));<br />
lstrcpy(nid.szTip,"...some text ...");<br />
Shell_NotifyIcon(NIM_ADD,&nid);<br />
... and do not forget to remove the icon from tray when ready

Does anyone have the sources of Filemon from sysinternals web site?
It was published several years ago but the guys over there decided to remove it.

Try this:
CComPtr<IADsNameTranslate> pNto;
HRESULT hr=S_OK;
USES_CONVERSION;
WKSTA_INFO_100* pWkStaInfo=NULL;
CString strDomainName;
if (NetWkstaGetInfo(NULL, 100, (LPBYTE*)&pWkStaInfo)==NERR_Success) {
strDomainName=(OLE2CT((WCHAR*)pWkStaInfo->wki100_langroup));
NetApiBufferFree(pWkStaInfo);
}
Cheerz,

if you looking for local domain you can depend upon GetNetworkParams api!

hi,
i got the following problem. i'm writing an mfc mdi (derived from CScrollView) proram for displaying the samples of a wav file. everythnig works fine so far, but every time i scroll in my window the whole content (which is quite much)is repainted. i heard that this could be avoided by only painting the content once, creating a bitmap from it and in the future just use this bitmap whenever a repaint is done, but i simply can't get this working. any advise for me?
thx
christian

You should use some boolean flags for the objects not to be drown all the time and set their values according to your needs.
Coming now to your bitmap approach, you could transform the DDB (device-dependent-bitmap) to a DIB (device-dependent bitmap ) by using the GetDIBits() function twice (once to get the image size and again to get the bits), then with the DIB handle you can use StretchDIBits() whenever you need to do something with your image.

CScrollView handles most of the problems, you should be able to keep it simple.
1) Add a CBitmap member to your view class.
2) Disable OnEraseBkgnd() (just return TRUE).
3) Create a screen compatible memory CDC.
4) Create your CDC compatible bitmap (size is upto you).
5) Select bitmap into CDC.
6) Draw on CDC.
7) Restore origanal bitmap to CDC.
8) Release CDC
9)
OnDraw(CDC* pDC)
{
....
pDC->BitBlt(0,0,nWidth,nHeight,dcTemp,0,0,SRCCOPY);
pDC->ExcludeClipRect(0,0,nWidth,nHeight);
CRect rcClip;
pDC->GetClipBox(&rcClip);
pDC->FillSolidRect(
rcClip.left,rcClip.top,
rcClip.Width(),rcClip.Height(),
::GetSysColor(COLOR_WINDOW));
....
}
Well that should work.
You would normaly update the bitmap (create) in the OnInitialUpdate() or OnUpdate() functions as well as update the scrollbar limits. You'll want to write a seperate function UpdateScrollSizes() to update scrollbar limits, if you plan on adding a zoom feature.

thx for the fast answers, works better now but something is still wrong. i used your solution john, here is my code :
BOOL CGALWaveView::OnEraseBkgnd(CDC* pDC)
{
return TRUE;
}
void CGALWaveView::OnInitialUpdate()
{
CScrollView::OnInitialUpdate();
CSize sizeTotal;
CRect rect;
this->GetClientRect(&rect);
CDC pDC;
pDC.CreateCompatibleDC(&pDC);
//m_background is the image this->m_background.CreateCompatibleBitmap(&pDC,rect.Width()*GetDocument()->m_zoomFactor,rect.Height()*GetDocument()->m_zoomFactor);
pDC.SelectObject(&m_background);
OnDraw(&pDC);
sizeTotal.cx = rect.Width()*(long)GetDocument()->m_zoomFactor;
sizeTotal.cy = rect.Height();
SetScrollSizes(MM_TEXT, sizeTotal);
}
void CGALWaveView::OnDraw(CDC* pDC) {
CRect rect;
this->GetClientRect(&rect);
int zoom = GetDocument()->m_zoomFactor;
if (m_isDrawn==FALSE || m_zoomChanged==TRUE) {
...some drawing...
m_isDrawn=TRUE;
m_zoomChanged=FALSE;
}
else {
CDC* temp=NULL;
pDC->BitBlt(0,0,rect.Width()*zoom,rect.Height()*zoom,temp,0,0,SRCCOPY);
pDC->ExcludeClipRect(0,0,rect.Width()*zoom,rect.Height()*zoom);
}
now i got the problem that only the visible part is drawn, and whenever i scroll left or rigth, there is only white background.
any ideas?
thx
