can someone please help me with this code:

[dimava]

I got this code from a thing at PlanetSourceCode.com, this is a simple program with 2 command buttons, a status bar, and a progress bar:

Dim q As String, ahgt, ghtr As String
Dim id As Long, v As Long, i As Long, lVol As lVolType, Vol As VolType, lv As Double, rv As Double

Private Declare Function auxGetVolume Lib "WINMM.DLL" (ByVal uDeviceID As Long, lpdwVolume As Long) As Long

Private Declare Function mciGetDeviceID Lib "WINMM.DLL" Alias "mciGetDeviceIDA" (ByVal lpstrName As String) As Long

Private Declare Function waveOutGetVolume Lib "WINMM.DLL" (ByVal uDeviceID As Long, lpdwVolume As Long) As Long

Private Declare Function waveOutSetVolume Lib "WINMM.DLL" (ByVal uDeviceID As Long, ByVal dwVolume As Long) As Long

Private Declare Function GetSystemMetrics Lib "user32" (ByVal nIndex As Long) As Long

Private Type lVolType
    v As Long
    End Type

Private Type VolType
    lv As Integer
    rv As Integer
    End Type

Private Sub Command1_MouseDown(Button As Integer, Shift As Integer, X As Single, Y As Single)
    If q = "1" Then
        Exit Sub
    End If
    id = -0
    i = waveOutGetVolume(id, v)
    lVol.v = v
    LSet Vol = lVol
    lv = Vol.lv: rv = Vol.rv
    lv = lv - &HFFF
    rv = rv - &HFFF
    If lv < -32768 Then lv = 65535 + lv
    If rv < -32768 Then rv = 65535 + rv
    Vol.lv = lv
    Vol.rv = rv
    LSet lVol = Vol
    v = lVol.v
    i = waveOutSetVolume(id, v)
    Call Findout
    StatusBar1.SimpleText = ProgressBar1.Value
End Sub

Private Sub Command2_MouseDown(Button As Integer, Shift As Integer, X As Single, Y As Single)
    If q = "10" Then
        Exit Sub
    End If
    Dim dfre
    j = 1
    id = -0
    i = waveOutGetVolume(id, v)
    lVol.v = v
    LSet Vol = lVol
    lv = Vol.lv: rv = Vol.rv
    lv = lv + &HFFF
    rv = rv + &HFFF
    'If lv <= -30000 Then Exit Sub
    If lv > 32767 Then lv = lv - 65536
    If rv > 32767 Then rv = rv - 65536
    Vol.lv = lv
    Vol.rv = rv
    LSet lVol = Vol
    v = lVol.v
    i = waveOutSetVolume(id, v)
    Call Findout
    StatusBar1.SimpleText = ProgressBar1.Value
End Sub

Private Sub Form_Load()
    Call Findout
End Sub

Sub Findout()
    id = -0
    i = waveOutGetVolume(id, v)
    lVol.v = v
    LSet Vol = lVol
    lv = Vol.lv: rv = Vol.rv
    lv = lv - &HFFF
    rv = rv - &HFFF
    If lv < -32768 Then lv = 65535 + lv
    If rv < -32768 Then rv = 65535 + rv
    Vol.lv = lv
    Vol.rv = rv
    LSet lVol = Vol
    v = lVol.v
    ghtr = Left(lv, 1)

    If ghtr = "-" Then
        GoTo erre
    End If

    If lv < 5000 Then
        q = 1
        GoTo sayit
    End If

    If lv < 10000 Then
        q = 2
        GoTo sayit
    End If

    If lv < 15000 Then
        q = 3
        GoTo sayit
    End If

    If lv < 20000 Then
        q = 4
        GoTo sayit
    End If

    If lv < 25000 Then
        q = 5
        GoTo sayit
    End If

    If lv < 30000 Then
        q = 6
        GoTo sayit
    End If

erre:
    If lv < (-28000) Then
        q = 7
        GoTo sayit
    End If

    If lv < (-22000) Then
        q = 8
        GoTo sayit
    End If

    If lv < (-15000) Then
        q = 9
        GoTo sayit
    End If

    If lv < (-8000) Then
        q = 10
        GoTo sayit
    End If

sayit:
    ProgressBar1.Value = q
End Sub

how do i made it so that a slide bar controls the volume?

I think that you have an event on the slider control (Slider_Change) and use this with the WaveOutSetVolume function

Possible E.g.

Private Sub Slider1_change()
Dim NewVol as long
NewVol=(slider1.value/10) * MaxVolumeVal

call WaveOutSetVolume(DeviceID,NewVol)
End Sub

I haven't tested this as I don't have a sound card at work, but this may help you sort the problem
