Would it be possible send a click message using SendMessage to a control in parent window?
Apparently, the following doesn't seem to be working
SendMessage(hParent, WM_LBUTTONDOWN, MK_LBUTTON, MAKELPARAM(x, y));
SendMessage(hParent, WM_LBUTTONUP, 0, MAKELPARAM(x, y));
//x and y are location of child control on parent applet window.
