can someone please help me with this code:

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:

Code:

---

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

    If q = "1" Then
        Exit Sub

    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

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

[Edited by dimava on 11-09-2000 at 10:25 PM]

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
