var WM_HSCROLL = 0x0114;
var WM_VSCROLL = 0x0115;

function OnEvent_Initialize(bMessengerStart){
     // Create a window that theoretically contains both a horizontal and vertical scrollbar.
     var pWnd = MsgPlus.CreateWnd("ScrollbarExample.xml", "ScrollbarWnd");
     // Register message notifications for each type of scrollbar
     pWnd.RegisterMessageNotification(WM_HSCROLL);
     pWnd.RegisterMessageNotification(WM_VSCROLL);
}

// An event for the window
function OnScrollbarWndEvent_MessageNotification(pWnd, nMessage, wParam, lParam){
     // check which message it is
     switch(nMessage){
          case WM_HSCROLL: // if it is the horizontal one
               Debug.Trace("Horizontal scrollbar changed!");
               break; // so it doesn't go on
          case WM_VSCROLL: // if it is the vertical one
               Debug.Trace("Vertical scrollbar changed!");
               break; // so it doesn't go on
     }
     // let Windows process the message like normal
     return -1;
