volume regulating program

[lucius]

Tell me please how to call a volume regulating program (sndvol32.exe in WinXP) in order that a simple slider would appear but not whole program with all the functions.

Here is the way to "get" the current sound level..,.

;Get Wav Sound Volume
; Author gafrost
#include <GUIConstants.au3>
MsgBox(0,"", _SoundGetWaveVolume())
Func _SoundGetWaveVolume()
    Local $WaveVol = -1, $p, $ret
    Const $MMSYSERR_NOERROR = 0
    $p = DllStructCreate ("dword")
    If @error Then
        SetError(2)
        Return -2
    EndIf
    $ret = DllCall("winmm.dll", "long", "waveOutGetVolume", "long", -1, "long", DllStructGetPtr ($p))
    If ($ret[0] == $MMSYSERR_NOERROR) Then
        $WaveVol = Round(Dec(StringRight(Hex(DllStructGetData ($p, 1), 8), 4)) / 0xFFFF * 100)
    Else
        SetError(1)
    EndIf
    $Struct=0
    Return $WaveVol
EndFunc;==>_SoundGetWaveVolume
