    Specifies that the parameter gives the command ID of the existing menu item. This is the default if neither MF_BYCOMMAND nor MF_BYPOSITION is set.

    MF_BYPOSITION

    Specifies that the parameter gives the position of the existing menu item. The first item is at position 0.

Return Value

Nonzero if successful; otherwise 0

Remarks

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. The checked item is displayed using a radio button (or bullet) bitmap instead of a check mark bitmap.
