How to make plugins work nicely under nad and winamp
-----------------------------------------------------

Write a plugin that 'attaches' itself to the calling app window, or
just simply want to change the text the window displays so people
using the plugin think more of it??

Well these simple instructions will help you do just that. Or at the
least it will let you bring up a dialog that says 'nad stinks' or
something :P


The code you need to know
-------------------------

When nad is about to call your module Init() code, it sets the userdata
of the window which you can use to detect its running.

1> its sets its own window UserData to the hex value 0x004e4144,
	(this is the ascii hex value for 'nad'(with a leading null).

so in your plugin you can call

	if(GetWindowLong(TheModule->hwndParent, GWL_USERDATA) == 0x004e4144)
		IsNad = TRUE;

that should work and you can use different code somewhere to
do whatever it takes to make your plugin work with nad!

Nad Extensions to the Winamp Plugin Format
------------------------------------------

all messages are sent to the Parent window from the winampvismodule structure...

	#define WM_PLUGIN_ATTACHWINDOW		WM_APP + 0x0400
	/* lParam points to your window. Sending this message means your plugin will receive messages
	to the window you specify (see below for the messages you will receive*/

	// for the following messages use SendMessage and get the return value
	#define WM_PLUGIN_GETCURRENTTIME	WM_APP + 0x0402		// time in seconds
	#define WM_PLUGIN_GETBITRATE		WM_APP + 0x0403
	#define WM_PLUGIN_GETSAMPLEFREQ		WM_APP + 0x0404
	#define WM_PLUGIN_GETSYNCSTATUS		WM_APP + 0x0405		// see below for possible return values
	#define WM_PLUGIN_GETPLAYSTATUS		WM_APP + 0x0406		// ''   ''   ''   ''       ''     ''
	#define WM_PLUGIN_GETUPDATERATE		WM_APP + 0x0407		// number of FPS 

	#define WM_PLUGIN_INWINDOWACTIVE	WM_APP + 0x0408
	/* Makes nad turn off display into the big boxso your plugin can draw into this window..
	the dimensions are 147x42 at an offset of */

	#define WM_PLUGIN_WINDOW_MESSAGE	WM_APP + 0x0409
	/* lParam points to NULL terminated message.. This message allows you to put a message in the
	main nad window song display for 3seconds or so..*/

If you use the WM_PLUGIN_ATTACHWINDOW message your plugin window will receive the following messages

	#define WM_TIME			WM_APP + 0x0201
	#define WM_PLAYING		WM_APP + 0x0205
	#define WM_STOPPED		WM_APP + 0x0206
	#define WM_SYNC_STATUS		WM_APP + 0x0207

these are the values from WM_PLUGIN_GETPLAYSTATUS
	#define PLAYING			0
	#define PAUSED			1
	#define STOPPED			2

these are the values from WM_PLUGIN_GETSYNCSTATUS and WM_SYNC_STATUS
	#define SYNC_GOOD		0
	#define SYNC_BAD		1
	#define SYNC_SKIPWAV		2
