SUMMARY
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.
