Basically for the sendto menu, do this:
librarySendToMenuStruct s={0,};
int IPC_LIBRARY_SENDTOMENU=SendMessage(hMainWindow,WM_WA_IPC,(WPARAM)&"LibrarySendToMenu",IPC_REGISTER_WINAMP_IPCMESSAGE);
if (IPC_LIBRARY_SENDTOMENU > 65536 && SendMessage(hMainWindow,WM_WA_IPC,(WPARAM)0,IPC_LIBRARY_SENDTOMENU)==0xffffffff)
{
s.mode=1;
s.hwnd=myWnd;
s.data_type=mydatatype;
s.build_hMenu=mysubmenu;
}
TrackPopupMenu();
if (ret)

if (unrecognized ret)
{
if (s.mode == 2)
{
s.menu_id=ret;
if (SendMessage(hMainWindow,WM_WA_IPC,(WPARAM)&s,IPC_LIBRARY_SENDTOMENU)==0xffffffff)
{
// build my data.
s.mode=3;
s.data=my data;
SendMessage(hMainWindow,WM_WA_IPC,(WPARAM)&s,IPC_LIBRARY_SENDTOMENU)
// free my data
}
}
}
}
if (s.mode)

s.mode=4;
SendMessage(hMainWindow,WM_WA_IPC,(WPARAM)&s,IPC_LIBRARY_SENDTOMENU) // cleanup

s.mode=2;
}
kinda complex and gross, yes?
