Here is a routine that generically scrolls any control with a vertical 
scrollbar up or down :-

void scrllctrl(TWinControl *mjctl,bool goup)
{
  tagPOINT mpt,clcrds;
  GetCursorPos(&mpt);
  clcrds.x=mjctl->Width-7;
  clcrds.y = (goup) ? 7 : mjctl->Height-7;
  ClientToScreen(mjctl->Handle,&clcrds);
  SetCursorPos(clcrds.x,clcrds.y);
  mouse_event(MOUSEEVENTF_LEFTDOWN,clcrds.x,clcrds.y,0,0);
  mouse_event(MOUSEEVENTF_LEFTUP,clcrds.x,clcrds.y,0,0);
  Application->ProcessMessages();
  SetCursorPos(mpt.x,mpt.y);
}

Simply use
scrllctrl(CppWebBrowser1,true); to scroll it up and
scrllctrl(CppWebBrowser1,false); to scroll it down.

HTH,
