SoundSentryProc
The SoundSentryProc function is a library-defined callback function that produces a customized
visual signal when the SoundSentry accessibility feature is on and a
Windows-based application (or a non-Windows-based application running in a window)
generates a sound through the computer's built-in speaker.
LRESULT CALLBACK SoundSentryProc(
DWORD dwMillisec,
| // duration of visual signal
| DWORD fdwEffect
| // effect-type flag
| );
|
|
Parameters
dwMillisec
Specifies the duration, in milliseconds, of the visual signal that is
displayed when a Windows-based application (or a non-Windows-based application running
in a window) generates a sound.
fdwEffect
Specifies the type of visual signal to display. Currently, this value must
always be SSWF_CUSTOM.
Return Values
If the visual signal was or will be displayed correctly, the return value is
TRUE. If the signal is asynchronous and the status is not available when the
function is called, it should return TRUE.
If an error prevented the signal from being displayed, the return value is
FALSE. To get extended error information, call GetLastError.
Remarks
The library that contains the SoundSentryProc function must be a 32-bit DLL, and the DLL must export a function with the
name "SoundSentryProc."
The SoundSentryProc function is called only after an application or library calls the SystemParametersInfo function, specifying the SPI_SETSOUNDSENTRY value and the address of a SOUNDSENTRY structure whose iWindowsEffect member is set to SSWF_CUSTOM.

Nostalgia .Net |
|
.Net is powerful, but not all-powerful, so sometimes we need to use Win32 API for our .Net applications. It's simple enough with Platform Invoke if you have Win32 skill, but we do not always have time to dig the ancient documentation, declare the special types that are compatible with Win32, find the values of the Win32's constants and so on. Nostalgia .Net offers several simple-to-use classes, and components that will allow you to forget about the headache of Win32 and just use the power of Win32 in your application the same way as you use the native. Net classes. More » |
