CONST_DDEDMFLAGS

The CONST_DDEDMFLAGS enumeration is used in the flags parameter of the DirectDraw7.GetDisplayModesEnum method to specify the type of enumeration.

Enum CONST_DDEDMFLAGS
    DDEDM_DEFAULT          = 0
    DDEDM_REFRESHRATES     = 1
    DDEDM_STANDARDVGAMODES = 2
End Enum
DDEDM_DEFAULT
Performs a normal enumeration of the display modes.
DDEDM_REFRESHRATES
Enumerates modes with different refresh rates. This guarantees that a particular mode is enumerated only once. This flag specifies whether the refresh rate is taken into account when determining if a mode is unique.
DDEDM_STANDARDVGAMODES
Enumerates Mode 13 in addition to the 320x200x8 Mode X mode.
