Question

Have menu with some item, need change it to MF_CHECKED or MF_UNCHECKED.
And how to check up what item of menu is checked now?

Answer 1

You can retrieve the check state among other information by calling GetMenuItemInfo. It fills a MENUITEMINFO structure. It's fState member will have the MFS_CHECKED flag set, if the menu item is checked.

To modify the check state of a menu item you call SetMenuItemInfo. There is also a utility function CheckMenuItem. The docs state that this API call may not be available in versions after Windows 2000. However, it still is.

Answer 2

Just keeping the state of the menu in your own variables is the straight-forward solution. But you can use GetMenuItemInfo() to retrieve the state of a menu item, MENUITEMINFO.fState field.
