The application sends this message to IPF to indicate that the previous DDF data is no longer valid.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.
- The pointer to an array of unsigned 16-bit (USHORT) integers that are the res
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.
