Playing audio files.

[jobs_arghya]

Dear all,

Hope all in fine tune.

I am creating a media player project. I am taking the list of audio files (.mp3) in a list box. Now I want them to be played one by one starting from the top of the list box.

I am writing the code in a loop where I am taking a loop which runs from the 0th Index to the index=Items.Count-1

But while playing only the last song is played. How can I rectify this problem. Please help me.

Private Sub PlaySong()
        Dim i As Integer
        i = 0
        Do While i < Playlist.Items.Count
            Playlist.GetSelected(i)
            PlayerControl.URL = Playlist.Items.Item(i)
            If PlayerControl.URL <> "" Then
                'PlayerControl.Ctlcontrols.play()
                'DurationTimer.Enabled = True
            Else
                DurationTimer.Enabled = False
            End If
            i = i + 1
        Loop
    End Sub

Depending on what version of visual basic you currently own, Rumor has it, version 6.0 and lower supports only ".wav" audio files, so you must convert your .mp3 perhaps?

It looks to me that the loop you show does play every song in the list but it does not appear to wait for a song to finish before playing the next one.

There are several audio controls compatible with Vb6 that support practically all audio formats. I recommend either .mp3 or .wma rather than .wav files that are much larger. Either one of these two audio file formats have no loss in sound quality while saving lots of disk space and memory.

VB6 as well as 5 can play mp3 because windows can play mp3. Add this code to a module and you can start Jammin':

Public Declare Function GetShortPathName Lib "kernel32" Alias "GetShortPathNameA" (ByVal lpszLongPath As String, ByVal lpszShortPath As String, ByVal cchBuffer As Long) As Long
Public Declare Function mciSendString Lib "winmm.dll" Alias "mciSendStringA" (ByVal lpstrCommand As String, ByVal lpstrReturnString As String, ByVal uReturnLength As Long, ByVal hwndCallback As Long) As Long
Public Function Play_MM(song As String)
    Dim shortpath As String, pathlength As Long
    
    shortpath = Space(250)
    pathlength = GetShortPathName(song, shortpath, Len(shortpath))


    If pathlength Then
        shortpath = Left$(shortpath, pathlength)
    End If
    
    mciSendString "Close MM", 0, 0, 0
    mciSendString "Open " & shortpath & " Alias MM", 0, 0, 0
    mciSendString "Play MM", 0, 0, 0
End Function
Public Function Pause_MM()
    If Paused = False Then
        mciSendString "Pause MM", 0, 0, 0
        Paused = True
    Else
        mciSendString "Play MM", 0, 0, 0
        Paused = False
    End If
End Function
Public Function Stop_MM()
    mciSendString "Stop MM", 0, 0, 0
    mciSendString "Close MM", 0, 0, 0
End Function

You can check if the songs still playing by :

s = Space(128)
x = mciSendString("status MM mode", s, Len(s), 0)

If Left(s, 7) = "stopped" Then
    'do stopped stuff
ElseIf Left(s, 7) = "playing" Then
    'do playing stuff
end if

stick that part in a timer

Here let me put it together for you.
This program will read the XP My Music directory and play it:

1 form and 1 listbox

Option Explicit

Private Declare Function GetShortPathName Lib "kernel32" Alias "GetShortPathNameA" (ByVal lpszLongPath As String, ByVal lpszShortPath As String, ByVal cchBuffer As Long) As Long
'Declaration for the winmm dll
Private Declare Function mciSendString Lib "winmm.dll" Alias "mciSendStringA" (ByVal lpstrCommand As String, ByVal lpstrReturnString As String, ByVal uReturnLength As Long, ByVal hwndCallback As Long) As Long
Private Sub Form_Load()
Dim env As String, x As String, test As String, i As Integer
Me.Show
env = Environ("USERPROFILE") & "\My Documents\My Music\"
List1.Clear
x = Dir(env & "*.mp3")
Do While x <> ""
List1.AddItem x
x = Dir()
Loop

For i = 0 To List1.ListCount - 1
    Play_MM env & List1.List(i)
    DoEvents
    test = "playing"
    While Left(test, 7) = "playing"
        test = Space(128)
        x = mciSendString("status MM mode", test, Len(test), 0)
        DoEvents
    Wend
Next
End Sub
Public Function Play_MM(song As String)
    Dim shortpath As String, pathlength As Long
    
    shortpath = Space(250)
    pathlength = GetShortPathName(song, shortpath, Len(shortpath))


    If pathlength Then
        shortpath = Left$(shortpath, pathlength)
    End If
    
    mciSendString "Close MM", 0, 0, 0
    mciSendString "Open " & shortpath & " Alias MM", 0, 0, 0
    mciSendString "Play MM", 0, 0, 0
End Function
Private Sub Form_Unload(Cancel As Integer)
mciSendString "Close MM", 0, 0, 0
End
End Sub

Post edited to add the end command
