What makes "typedef struct {} name" better than just "struct name"?

i tried this:

SendMessage (theHwnd, WM_LBUTTONDOWN, /*the constant for lmousekey, i can#t remember*/, MAKELPARAM(y,x));

::SendMessage(hOwnerWnd,WM_COMMAND,MAKELONG(IDOK,BN_CLICKED),0);
::SendMessage(hButton,BM_CLICK,0,0);

const long nClickingPoint= 5;
POINT pt;
// X and y are point you are talking about
pt.x = x + nClickingPoint;// to make click inside button
pt.y = y + nClickingPoint;// to make click inside button
CWnd * pCtrl = WindowFromPoint(pt);//this will return window at that point
pCtrl->SendMessage(WM_LBUTTONDOWN,0,MAKELPARAM((nClickingPoint),(nClickingPoint)));
pCtrl->SendMessage(WM_LBUTTONUP,0,MAKELPARAM((nClickingPoint),(nClickingPoint)));
