Used to access DWORD properties.

typedef struct DIPROPDWORD { 
    DIPROPHEADER diph; 
    DWORD        dwData; 
} DIPROPDWORD, *LPDIPROPDWORD; 

typedef const DIPROPDWORD *LPCDIPROPDWORD;

Members

diph

DIPROPHEADER structure that must be initialized as follows:

Member	Value
dwSize	sizeof(DIPROPDWORD)
dwHeaderSize	sizeof(DIPROPHEADER)
dwObj	If the dwHow member is DIPH_DEVICE, this member must be 0. If the dwHow member is DIPH_BYID, this member must be the identifier for the object whose property setting is to be set or retrieved. If the dwHow member is DIPH_BYOFFSET, this member must be a data format offset for the object whose property setting is to be set or retrieved. For example, if the c_dfDIMouse data format is selected, it must be one of the DIMOFS_* values. If the dwHow member is DIPH_BYUSAGE, the device must be a Human Interface Device (HID). The device object will be identified by the HID usage page and usage values in packed form.
dwHow	Specifies how the dwObj member should be interpreted. See the preceding description of the dwObj member for details.

dwData

Property-specific value being set or retrieved.
