Winamp and Visual Basic

Okay Im writing a little interface program for winamp w/VB. I have been to their develpoer forums and no one seems to know why this code doesn't work.    
Ok, this is a snippet of my code fom VB...

==========================================================Private Const WM_USER = &H400
Private Const MODE = 1
Private Const IPC_GETTIME = 105
Dim s as Long

Private Sub Command6_Click()

s = SendMessage(hwndWinamp, WM_USER, MODE, IPC_GETTIME)
MsgBox s

End Sub
==========================================================This code is supposed to return the current songs position
in seconds. The only value it ever returns is 1. It will not give time in Seconds. Just a value of one. Does anybody see anything wrong or suggest anything. ( I use findwindow API to get the Hwnd of Winamp.)

I can't say for certain, but I would venture a guess that the Window Message you need to send to hwndWinamp is a certain value plus WM_USER.

WM_USER is a base-point reference for messages for private window classes.

here is an example from the SDK for Winamp (its in C++ but I ported it to VB,real simple)

--------------------------------------
#define IPC_GETOUTPUTTIME 105
/*
** int res = SendMessage(hwnd_winamp,WM_MA_IPC,mode,IPC_GETOUTPUTTIME);
**
** IPC_GETOUTPUTIME returns the position in milliseconds
** of the current (mode = 0), or the song length, in
** seconds(mode = 1).
** Returns -1 if not playing, 1 on EOF, or 0 if successful
*/

I forgot to mention that the constant WM_MA_IPC is defined as WM_USER.

Assuming your definition of WM_MA_IPC is correct (that it equals WM_USER and not something like WM_USER + 1), then I do not see any error off hand.

Docs on Winamp's site indicate the problem is probably in your definition of SendMessage!  Define the last paramater as ByVal Long instead of Any and you should be able to get your return value correctly.

So, you can use:

Public Declare Function SendMessage Lib "user32" Alias "SendMessageA" (ByVal hwnd As Long, ByVal wMsg As Long, ByVal wParam As Long, ByVal lParam As Long) As Long

Or declare a SendMessageLong type:

Public Declare Function SendMessageLong Lib "user32" Alias "SendMessageA" (ByVal hwnd As Long, ByVal wMsg As Long, ByVal wParam As Long, ByVal lParam As Long) As Long

and use it, retaining the default SendMessage definition.

I was looking for a winamp code that went beyong the normal play, pause, and stop functions. When I couldn't find it, i made it myself. This is the best winamp module on planetsourcecode, it does more than just play and stop, it can get song length, get

Just set you're volume or balance with two simple controls or set the position of the media. They can be used in every MP3 player. Currently they used Winamp skins but the code is easy to change to other formats
