VD

The VD structure is used to specify a view during run time. The structure is the first block of data written to the PR_VD_BINARY property when a view is saved. Data specified by pointers in this structure is appended after this structure in the PR_VD_BINARY property. When the VD structure is read in, the pointers are invalid.

    ULONG ulReserved1;

VDF_SORTDESCENDING

Indicates descending sort orders; if cleared indicates ascending sort orders.
