3.2.2.2 Category Property Example

This is an example of a Category property (Lpstr property (section 2.3.3.1.4)).

Offset	Size	Structure	Value
000000CC	0014	TypedPropertyValue - GKPIDDSI_CATEGORY
000000CC	0002	WORD - wType	0x001E
000000CE	0002	WORD - padding	0x0000
000000D0	0010	Lpstr - stringValue
000000D0	0004	DWORD - cch	0x0000000C
000000D4	000C	Array of CHAR - value	Tutorials

Figure 18: Structure of a Category property

GKPIDDSI_CATEGORY: Category.

wType: 0x001E indicates that this property is an Lpstr property (section 2.3.3.1.4).

stringValue.cch: 0x0000000C indicates that the count of characters of the Lpstr (section 2.3.3.1.4) value is 12. The value field contains 10 characters (9 for "Tutorials" plus a terminating NULL character). There are 2 additional bytes after the terminating NULL character which pad the value field to a multiple of 4 bytes.

stringValue.value: The value of this field is "Tutorials" followed by a null-terminator and 2 bytes of padding, so the length of this field is 0x0000000C (12). The 2 bytes of padding is added to make the length a multiple of 4 bytes.
