how to listen to winamp events

[ykahlon]

Hi,

I try to create an application that will listen to winamp events like playing a song, adding new song, etc...

I thought of creating a plugin that will post a message to my process each time I catch these events. My question is how can I do it.

For the plugin I know I need to do:

WNDPROC lpWinampWndProcOld;
LRESULT CALLBACK WinampWndProc(HWND hwnd, UINT message,
WPARAM wParam, LPARAM lParam) {
switch (message) {
case WM_WA_IPC :
if (lParam == IPC_PLAYING_FILE) {
// Here I need to post the message
}
break;
}
return
CallWindowProc(lpWinampWndProcOld,hwnd,message,
wParam,lParam);
}

// event functions follow
int init() {
lpWinampWndProcOld = (WNDPROC)SetWindowLong(plugin.hwndParent,GWL_WNDPROC,(LONG)WinampWndProc);
return 0;
}

My question is, how to post the message.

all depends on how you want to do it. you could just get a window handle from the application and just SendMessage(..)/PostMessage(..) to send it from the plugin to your app (using a WM_USER+? message range). or you could use a DDE based mechanism, mem-mapped file/structure, etc etc.

the options are pretty much countless, it just comes down to what form of inter-process communication you're looking for based on the complexity (or not) of any messages you might be sending.
