RDCOMPARE structure (mmc.h)

  • Article

The RDCOMPARE structure is introduced in MMC 1.2.

The RDCOMPARE structure is used by the IResultDataCompareEx::Compare method for specifying information used for sorting scope and result items in the result pane of a primary snap-in.

Syntax

typedef struct _RDCOMPARE {
  DWORD     cbSize;
  DWORD     dwFlags;
  int       nColumn;
  LPARAM    lUserParam;
  RDITEMHDR *prdch1;
  RDITEMHDR *prdch2;
} RDCOMPARE;

Members

cbSize

Size of this structure.

dwFlags

Reserved. Always zero.

nColumn

Column being sorted.

lUserParam

A value that specifies user-provided information that is passed into IResultData::Sort. MMC does not interpret this parameter.

prdch1

A pointer to an RDITEMHDR structure that specifies the first item's type (scope or result) and cookie.

prdch2

A pointer to an RDITEMHDR structure that specifies the second item's type (scope or result) and cookie.

Remarks

If the snap-in implements the IResultDataCompareEx interface, MMC MMC allocates the parameters to the IResultDataCompareEx::Compare snap-in's method and then calls the method. MMC releases the parameters after the method returns.
