How to do simple Winamp controls while winamp is minimized?

Hi guys

been searching through the forums and seems like there's a lot of winamp control scripts around here, but not exactly to what i wanted..

closes one i found was iNop's post here:
http://www.autohotke... ... ght=winamp

im trying to do something similar, that is to use my keyboard's multimedia keys to control winamp, but even if winamp isnt active..

i keep my winamp minimized in system tray most of the time.

I would like to control winamp while it is in the systemtray.


simple things i'd like to do is PLAY/PAUSE/STOP/FORWARD/BACK ..

can anyone help??

I believe the postmessage command should do what you need. Rajat posted a long list of winamp postmessage information underneath this tutorial:

http://www.autohotke...topic.php?t=126

ok.. i went through it... pretty easy on most apps.. did soem already for my different software..

however....

still no luck with winamp...

here's what i got so far:

PostMessage, 0x111, 40048,,,- Winamp

40048 is for next track as explained in your link.....

but how do i forward this command/message to winamp when it is minimized to the sytemtray?

Refer to this post.

Here is an example to get you started:

DetectHiddenWindows, On

; -- Windows message --
WM_COMMAND				= 0x0111
WM_USER            		= 0x0400

; -- Winamp commands --
WINAMP_PAUSE			= 40046
WINAMP_STOP				= 40047

; -- Winamp IPC message --
WM_WA_IPC         		:= WM_USER
IPC_ISPLAYING			= 104
/*	1	= playing
	3	= paused
	0	= not playing
*/

SendMessage, WM_USER, 0, IPC_ISPLAYING,, ahk_class Winamp v1.x
if ( ErrorLevel = 1 or ErrorLevel = 3 )
	SendMessage, WM_COMMAND, WINAMP_PAUSE, 0,, ahk_class Winamp v1.x
else
	MsgBox, Winamp is stopped.

;SendMessage, WM_COMMAND, WINAMP_STOP, 0,, ahk_class Winamp v1.x
return 

Hi,
first of all I'm totally newbie at scripting things

Like clever_j I've been seeking in these forums for a script that allows to control winamp while it is in the systemtray; I thought I've finally found the answer with this thread, but unfortunately there is not an complete answer, and I don't understand anything in scripting (I've tried to solve the problem myself with the few clues I've got, but it's simply too hard for me).
So, instead of creating a new thread, I prefer up this one.

here is the problem:
I've tried this script

DetectHiddenText, On
DetectHiddenWindows, On
winamppath = c:\program files\winamp\winamp.exe ;change winamp path here


;___________PLAY/PAUSE
Media_Play_Pause::
SendMessage, 0x400,0,104,,ahk_class Winamp v1.x
if errorlevel = 0
{
SendMessage, 0x111,40045,,,ahk_class Winamp v1.x
}

else
{
SendMessage, 0x111,40046,,,ahk_class Winamp v1.x
}

return

It works well when winamp is not in tray, otherwise it doesn't; also my winamp is always in tray, so this script is pretty useless for me ^^'

Does anyone knows a script that allow to control winamp (particularly pause/unpause) when he is in tray, and moreover when there is an application in full screen (like a game) ?
It would be great if someone takes me out of this scripting maze

ps: my OS is XP pro SP1


edit: ok, solved: it was an incompatibility with another script with an automatic execution section, so I made 2 separated scripts.

Does anyone found solution how to post messages to winamp when it is minimized to systray?
Does anyone know how to control it when it minimized to tray?

Russian guys are mega smart )
Just found solution for minimized to tray winamp in russian forum
I tested it is working!

I found the code to control winamp when it's minimized to the tray right in AHK help file, titled 'Automating Winamp'.

#z:: ; Previous song
IfWinNotExist ahk_class Winamp v1.x
    return
; Otherwise, the above has set the "last found" window for use below.
ControlSend, ahk_parent, z  ; Previous song
return

#x:: ; Play
IfWinNotExist ahk_class Winamp v1.x
    return
; Otherwise, the above has set the "last found" window for use below.
ControlSend, ahk_parent, x  ; Play
return

#c:: ; Pause
IfWinNotExist ahk_class Winamp v1.x
    return
; Otherwise, the above has set the "last found" window for use below.
ControlSend, ahk_parent, c  ; Pause
return

#v:: ; Next song
IfWinNotExist ahk_class Winamp v1.x
    return
; Otherwise, the above has set the "last found" window for use below.
ControlSend, ahk_parent, b  ; Next song
return

Here are some of the keyboard shortcuts available in Winamp 2.x (may work in other versions too). The above example can be revised to use any of these keys:

Key to send Effect
c Pause/UnPause
x Play/Restart/UnPause
v Stop
+v Stop with Fadeout
^v Stop after the current track
b Next Track
z Previous Track
{left} Rewind 5 seconds
{right} Fast-forward 5 seconds
{up} Turn Volume Up
{down} Turn Volume Down

i don't remember where i got this at, but I've been using it for a while:

;****************
;*              *
;*    Winamp    *
;*              *
;****************
Winamp(p_Command,p_Option=0)
    {
;-------------------------------------------------------------------------------
;
; Parameters        Description
; ==========        -----------
; p_Command         Winamp command/message.  This is a Winamp window command or
;                   a message to the Winamp program.  See the "Commands" section
;                   for more  information.  [Required]
;
; p_Option          Message option.  This parameter is only used if p_Command is
;                   idenfied as a WM_USER or WM_COPYDATA message.  The default
;                   value is 0.  [Optional]
;
;
;
; Commands
; ========
; There are 2 types commands:
;
;   1)  Window commands.  These commands allow you to determine the status of
;       the Winamp window(s) and to perform actions on these windows.  The
;       following commands are currently supported:
;
;           Command     Description/Return Code
;           -------     -----------------------
;           Active      Returns true if Winamp is active, false if it is not.
;
;           Activate    Activates the Winamp window.  Returns false if Winamp
;                       does not exist.
;
;           Exist       Returns true if the Winamp windows exist, false if they
;                       do not.
;
;           Minimize    If active, will minimize Winamp.  Returns false if
;                       Winamp does not exist.
;
;           Title       Returns the Winamp window title.  Depending on the
;                       configuration of Winamp, the title includes the artist
;                       and the song title of the current song.  This
;                       information can be extracted from the window title for
;                       other uses.
;
;
;   2)  Winamp message.  Winamp has been programmed to receive and respond to
;       a large number of messages sent to the primary Winamp window.  These
;       messages allow you to manipulate the Winamp and allow you to get the
;       current status of Winamp conditions.
;
;       Instead of using the raw Windows message components, this function uses
;       message "names" which are then converted into the standard message
;       components.  Once a message has been coded in this function, you only
;       have to remember (or look for) the appropriate message "name" in order
;       to use it.
;
;       Unfortunately, there are too many messages to document in this section.
;       Here's how to find/use the message names in the AHK code:
;
;       The message "names" can be extracted from the variables that begin with
;       "WA_WM_COMMAND_", "WA_WM_USER_" and "WA_WM_COPYDATA_".  For example, the
;       "WA_WM_COMMAND_NextTrack" variable is assigned the message that
;       instructs Winamp to skip to the next track in the playlist.  To send
;       this message to Winamp, simply call this function using "NextTrack" as
;       the command parameter, i.e. Winamp("NextTrack")
;
;
;   Notes
;   =====
;
;       Parameters
;       ----------
;       All spaces are removed from the p_Command parameter before the parameter
;       is processed.  This modification allows the function to use more
;       user-friendly (readable?) commands.  For example, the following all
;       execute the the same command:
;
;           Winamp("SetPlaylistPosition",273)
;           Winamp("Set PlaylistPosition",273)
;           Winamp("Set Playlist Position",273)
;
;
;       Winamp Versions
;       ---------------
;       Not all of the messages will work on all versions of Winamp.  Most
;       require version 2.0 or greater, many require version 2.05 or greater,
;       and a few require version 5.00 or greater.  Unfortunately, you have to
;       either do a "try it and see" or you have to download the SDK to
;       determine if the message will work with your version.  If you have a
;       fairly recent version of Winamp, it is likely that everything will work.
;       See the "References and Credit" section for more information.
;
;
;       Return Codes
;       ------------
;       The return codes for the Window commands are documented in the
;       "Commands" section above.
;
;       The return codes for the Winamp messages, if applicable, are documented
;       within the code.  If Winamp is not running or if the message "name" is
;       not is not found, return code 999 is returned.
;
;
;
;   References and Credit
;   =====================
;   Only a small fraction of the total number of Winamp messages have been
;   included in this function.  See the following posts for more complete list

;   Examples Of Use
;   ===============
;   Here are a few examples of how this function can be used in a script:
;
;   ;----- Start of examples -----
;   ^#!Up::Winamp("Play")  ;-- Nothing will happen if Winamp is not running.
;
;   ^#!Down::
;   if Winamp("Exist")  ;-- winamp running?
;       if Winamp("Is Playing")=1  ;-- Playing? (Check to avoid Pause toggle)
;           Winamp("Pause")
;   return
;   
;   ^#!Left::Winamp("Previous Track")  ;-- Go back 1 track
;   
;   ^#!Right::Winamp("Next Track")  ;-- Skip to the next track
;   ;----- End of examples -----
