DOCERR: ICM_DECOMPRESSEX_QUERY dwParam1 and dwParam2 Incorrect

 Last reviewed: May 16, 1995

The information in this article applies to:
  • Microsoft Windows Software Development Kit (SDK) for Windows, version 3.1
  • Microsoft Video for Windows Development Kit (DK), version 1.1

The online help (DK_DOC.HLP or DK_DOC.MVB) in the Microsoft Video for Windows DK incorrectly documents the ICM_DECOMPRESSEX_QUERY message. The incorrect documentation states the following: 

   dwParam1 - Specifies a far pointer to an ICDECOMPRESSEX data
   structure describing the input format.

   dwParam2 - Specifies zero or a far pointer to an ICDECOMPRESSEX data
   structure used to return the output format. Zero indicates that any
   output format is acceptable.
The correct documentation for this message is listed below: 

   dwParam1 - Specifies zero or a far pointer to an ICDECOMPRESSEX data
   structure used to return the output format. Zero indicates that any
   output format is acceptable.

   dwParam2 - Contains the size in bytes of the structure pointed to by
   dwParam1.
The ICSAMPLE sample code from the Microsoft Video for Windows DK correctly handles the ICM_DECOMPRESSEX_QUERY message.

NOTE: The similarly named ICM_DECOMPRESS_QUERY message is documented correctly.
