MessageBox() without a beep

No.  If the user has a sound attached to the "Exclamation" or "Asterisk" event, the sound will play when a message box comes. It's the user's individual choice, and you should respect it.

Otherwise, you can't respect it, then you'll have to avoid the MessageBox() API. You can create your own popup window that shows your text and doesn't trigger any of the sound events on the system.

Not that I like disagreeing with mikeblas - I have used MessageBoxIndirect to do what you want to do (no beep).

By filling in the lpMsgBoxParams params you can substitute your own procedure (similar to a dlgproc) - you can remove the beep in the WM_INITDIALOG procedure by returning TRUE


int MessageBoxIndirect(
CONST LPMSGBOXPARAMS lpMsgBoxParams  // message box parameters
);

Interesting!  That really does get around it?

I'll dig out and post the code shortly (its presently archived)

I was wrong about the callback - my memory did not serve me well - but alas I knew I had done it before so .... OK guys - this is how it is done


MSGBOXPARAMS lpMsgBoxParams;

lpMsgBoxParams.cbSize = sizeof(MSGBOXPARAMS);
lpMsgBoxParams.hwndOwner = hDlg;
lpMsgBoxParams.hInstance = hInstance;
lpMsgBoxParams.lpszText = "This is a message box created with the MessageBoxIndirect API";
lpMsgBoxParams.lpszCaption = "This is a MessageBox";
lpMsgBoxParams.dwStyle = MB_OKCANCEL |MB_USERICON ;
lpMsgBoxParams.lpszIcon = MAKEINTRESOURCE(IDI_ICON1);
//lpMsgBoxParams.dwContextHelpId =
//lpMsgBoxParams.lpfnMsgBoxCallback = (MSGBOXCALLBACK) MsgBoxCallBack;
//lpMsgBoxParams.dwLanguageId =

/*
  typedef struct {
  UINT      cbSize;
  HWND      hwndOwner;
  HINSTANCE hInstance;
  LPCTSTR   lpszText;
  LPCTSTR   lpszCaption;
  DWORD     dwStyle;
  LPCTSTR   lpszIcon;
  DWORD_PTR dwContextHelpId;
  MSGBOXCALLBACK lpfnMsgBoxCallback;
  DWORD     dwLanguageId;
} MSGBOXPARAMS, *PMSGBOXPARAMS;
*/
      MessageBoxIndirect(&lpMsgBoxParams);

I hope the code formats correctly here.

In the dwStyle parameter you must use the MB_USERICON flag with a standard flag - if you dont you get a beep. Using the MB_USERICON flag seems to remove the beep.

ie lpMsgBoxParams.dwStyle = MB_OKCANCEL |MB_USERICON ;


The lpszIcon parameter must be set to a user defined icon (in this instance IDI_ICON1).

The rest of the parmeters are well documented.

Is this what was wanted ??

If you want complete sample code to compile in VC++ 6 then give me the private email address and I'll send it to you.

The answer that DarrinE gave in
the form of a comment was awesome.
It worked like a charm.  I want
to give the points to him.

DarrinE - Post an answer just saying
you want the points and I will give
them to you.

Thanks!

So, is it true that MessageBoxIndirect() really does skip the user's settings for sounds?

Yes it works as long as you put
MB_USERICON for dwStyle.

>>Yes it works as long as you put

Combine it with the standard flags - without it - the normal sounds come through

DarrinE

 > Yes it works as long as you put

Cool!

 > MB_USERICON for dwStyle.  

Looks like that works to silence a regular MessageBox() call, as well.
