DIDATAFORMAT

The DIDATAFORMAT type carries information describing a device's data format. This type is used with the DirectInputDevice.SetDataFormat method.

Type DIDATAFORMAT
    dataSize As Long
    lFlags As Long
    lObjSize As Long
    numObjs As Long
End Type

Members

dataSize

Size of a data packet returned by the device, in bytes. This value must be a multiple of 4 and must exceed the largest offset value for an object's data within the data packet.

lFlags

Flags describing other attributes of the data format. This value can be one of the CONST_DIDATAFORMATFLAGS enumeration.

lObjSize

Size of the DIOBJECTDATAFORMAT type, in bytes.

numObjs

Number of objects for which data is to be returned.

Remarks

Applications need to create a DIDATAFORMAT type only for nonstandard devices. For the mouse, keyboard, and joystick, you set the data format by using DirectInputDevice.SetCommonDataFormat.
