As a beginner in C++ i am picking this up extremely fast, can anyone help me to figure out how to control the length the length of and play the system beep. I am writing a simple morse code program and this was what i was hoping to use.
Please help!!!
The Beep API function. You need NT to use this though (which you should -- NT/2000/XP are far superior now).Quote:
Beep
The Beep function generates simple tones on the speaker. The function is synchronous; it does not return control to its caller until the sound finishes.
BOOL Beep(
DWORD dwFreq, // sound frequency
DWORD dwDuration // sound duration
);
Parameters
dwFreq
[in] Specifies the frequency, in hertz, of the sound. This parameter must be in the range 37 through 32,767 (0x25 through 0x7FFF).
Windows 95/98/Me: The Beep function ignores this parameter.
dwDuration
[in] Specifies the duration, in milliseconds, of the sound.
Windows 95/98/Me: The Beep function ignores this parameter.
Return Values
If the function succeeds, the return value is nonzero.
If the function fails, the return value is zero. To get extended error information, call GetLastError.
Remarks
Terminal Services: The beep is redirected to the client.
Windows 95/98/Me: On computers with a sound card, the function plays the default sound event. On computers without a sound card, the function plays the standard system beep.
Example Code
For an example, see Registering a Control Handler Function.
Requirements
Windows NT/2000/XP: Included in Windows NT 3.1 and later.
Windows 95/98/Me: Included in Windows 95 and later.
Header: Declared in Winbase.h; include Windows.h.
Library: Use Kernel32.lib.
