I need to use this:

lResult = SendMessage( // returns LRESULT in lResult
(HWND) hWndControl, // handle to destination control
(UINT) TCM_SETITEMSIZE, // message ID
(WPARAM) wParam, // = (WPARAM) 0; not used, must be zero
(LPARAM) lParam // = (LPARAM) MAKELPARAM (cx, cy)
);

Parameters

wParam
Must be zero.
cx
New width, in pixels.
cy
New height, in pixels.

How would I create the LPARAM in VFP?
