It involves supplying your own window function for someone's window, and changing behavior by supplying your own logic for processing certain messages.<br /> <br /> Because your plugin is given Winamp's HWND during initialization, it is possible for your plugin to subclass Winamp's main window. Since the [[SendMessageAPI|Send Message API]] is built by sending messages to the Winamp window, your plugin can do a great deal without even effecting the UI. From simple notifications (e.g. Winamp sends msg=WM_WA_IPC, wParam=IPC_CB_MISC_TITLE, lParam=IPC_CB_MISC on song change) to radically altering behavior (e.g. Winamp checks the return value of msg=WM_WA_IPC, lParam=IPC_GET_NEXT_PLITEM to allow plugin's to override playlist playback order).</div>
