I had meet same question (not VB), some one tell me WinAMP SDK can do it.

Try enclosing a path to file in quotes.

I have tried that way and it can't work as well

Well... I have this:

' Module1
Module Module1
<System.Runtime.InteropServices.DllImport("shell32.dll", EntryPoint:="ShellExecute")> _
Public Function ShellExecute( _
ByVal hwnd As IntPtr, _
ByVal lpOperation As String, _
ByVal lpFile As String, _
ByVal lpParameters As String, _
ByVal lpDirectory As String, _
ByVal nShowCmd As Long) As Long
End Function

Public Sub Execute(ByVal hwnd As IntPtr, ByVal exeName As String, ByVal cmdLine As String)
ShellExecute(hwnd, vbNullString, exeName, cmdLine, vbNullString, 1)
End Sub
End Module

Somewhere in my code:

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
With Me.FolderBrowserDialog1
.SelectedPath = System.Environment.CurrentDirectory()
If (.ShowDialog(Me) <> DialogResult.Cancel) Then
Me.TextBox1.Text = .SelectedPath & "\Winamp.exe"
End If
End With
End Sub

Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click
With Me.OpenFileDialog1
.InitialDirectory = System.Environment.CurrentDirectory()
If (.ShowDialog(Me) <> DialogResult.Cancel) Then
Me.TextBox2.Text = .FileName
End If
End With
End Sub

Private Sub Button3_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button3.Click
Dim file As String = Chr(34) & Me.TextBox2.Text & Chr(34)
Execute(Me.Handle, Me.TextBox1.Text, file)
End Sub
End Class

This should give you a head-start

i have tried your code and execute it successfully. however, i encounter a new problem now cos i can't stop the player at predefined time. is there any alternative to stop the player at preset time?
i used Process class Wait*****it() method to stop other media player in predefined time. but i have no idea in shell funcion

Use a timer with:

#define IPC_GETOUTPUTTIME 105
/* int res = SendMessage(hwnd_winamp,WM_WA_IPC,mode,IPC_GETOUTPUTTIME);
** This api can return two different sets of information about current playback status.
**
** If mode = 0 then it will return the position (in ms) of the currently playing track.
** Will return -1 if Winamp is not playing.
**
** If mode = 1 then it will return the current track length (in seconds).
** Will return -1 if there are no tracks (or possibly if Winamp cannot get the length).
*/

or..

#define WINAMP_BUTTON4 40047 // stop button

at any time
