CheckMenuRadioItem
[Now
Supported on Windows NT]
The CheckMenuRadioItem
function checks a specified menu item and makes it a radio item. At the same
time, the function unchecks all other menu items in the associated group and
clears the radio-item type flag for those items.

HMENU hmenu, |
|
UINT idFirst, |
|
UINT idLast, |
|
UINT idCheck, |
|
UINT uFlags |

); |

Identifier or
position of the last menu item in the group.
idCheck

position of the menu item to check.

specifying the meaning of idFirst, idLast, and idCheck. If this
parameter is MF_BYCOMMAND, the other parameters specify menu item identifiers.

fails, the return value is zero. To get extended error information, use the GetLastError
Remarks
The CheckMenuRadioItem
function sets the MFT_RADIOCHECK type flag and the MFS_CHECKED state for the
item specified by idCheck and, at the same time, clears both flags for
all other items in the group. The checked item is displayed using a bullet
bitmap instead of a check-mark bitmap.
For more
information about menu item type and state flags, see the MENUITEMINFO
structure.
