DIPROPDWORD

The DIPROPDWORD is a generic structure used to access DWORD properties.

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

Members

diph

A 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 zero. 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 DIIMOFS_* values.
dwHow	Specifies how the dwObj member should be interpreted. If dwObj is DIPROP_AXISMODE or DIPROP_BUFFERSIZE, dwHow should be DIPH_DEVICE.

dwData

The property-specific value being set or retrieved.
