UNDONAMEID

[This is preliminary documentation and subject to change.]

The UNDONAMEID enumeration type contains values that indicate types of rich edit control actions that can be undone or redone. The EM_GETREDONAME and EM_GETUNDONAME messages use this enumeration type to return a value.

    UID_UNKNOWN    = 0,
    UID_TYPING     = 1,
    UID_DELETE     = 2,
    UID_DRAGDROP   = 3,
    UID_CUT        = 4,
    UID_PASTE      = 5
} UNDONAMEID;
