MMC_COLUMN_DATA structure (mmc.h)
The MMC_COLUMN_DATA structure is introduced in MMC 1.2.
The MMC_COLUMN_DATA structure contains the column data of a single column in a column set. The column data is persisted in memory by MMC. The MMC_COLUMN_SET_DATA structure holds a pointer to an array of MMC_COLUMN_DATA structures.
Syntax
typedef struct _MMC_COLUMN_DATA {
int nColIndex;
DWORD dwFlags;
int nWidth;
ULONG_PTR ulReserved;
} MMC_COLUMN_DATA;
Members
nColIndex
A zero-based index value of the column.
dwFlags
A flag that is defined, HDI_HIDDEN (= 0x0001), which indicates that the column is hidden. The default value for the field is 0, indicating that the column is visible.
nWidth
Width of the column.
ulReserved
Not currently used.
Remarks
By setting the dwFlags member of the MMC_COLUMN_DATA structure, a snap-in can hide or show columns in a column set in calls to IColumnData::SetColumnConfigData. However, column "0" of a column set cannot be hidden. This is to ensure that result pane icons are properly inserted in the first column and that the MMC_VERB_RENAME console verb functions properly.
