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.
