ShowHideMenuCtl
The ShowHideMenuCtl
function sets or removes the specified menu item s check-mark attribute, and
shows or hides the corresponding control. The function adds a check mark to the

check mark and hides the corresponding control.

Parameters
hWnd
Handle to the
window that contains the menu and controls.
uFlags
Identifier of
the menu item to receive or lose a check mark.
lpInfo
Pointer to an
array that contains pairs of values. The second value in the first pair must be
the handle to the application s main menu. Each subsequent pair consists of a
menu item identifier and a control window identifier. The function searches the
array for a value that matches uFlags and, if the value is found, checks
or unchecks the menu item and shows or hides the corresponding control.
Return Values
If the
function shows or hides the control, the return value is nonzero.
If the
function does not show or hide the control, the return value is zero.
