HM_INVALIDATE_DDF_DATA

The application sends this message to IPF to indicate that the previous DDF data is no longer valid.

Syntax

param1
ULONG rescount; /* The count of DDFs to be invalidated. */

param2
PUSHORT resarray; /* Pointer to an array. */

Parameters

rescount (ULONG) - input

The count of DDFs to be invalidated.

resarray (PUSHORT) - input

Pointer to an array.

The pointer to an array of unsigned 16-bit (USHORT) integers that are the res

numbers of DDFs to be invalidated.

Note: If both param1 and param2 are NULL, then all the DDFs in that

page will be invalidated.

Returns

rc (ULONG) - return

Return code.

0: The procedure was successfully completed.

Other: See the values of the errorcode parameter of the HM_ERROR message.

Remarks

When IPF receives this message, it discards the current DDF data and sends a new HM_QUERY_DDF_DATA message to the object communication window. This message should be sent to the child of the coverpage window handle.

Default Processing

None.
