MMC_FILTER_TYPE enumeration (mmc.h)

The MMC_FILTER_TYPE enumeration is introduced in MMC 1.2.

The MMC_FILTER_TYPE enumeration defines the filter type that is associated with a filter applied to a column in a filtered list. The values can be used in the dwType parameter of the IHeaderCtrl2::SetColumnFilter method and the pdwType parameter of the IHeaderCtrl2::GetColumnFilter method.

Syntax

typedef enum _MMC_FILTER_TYPE {
  MMC_STRING_FILTER = 0,
  MMC_INT_FILTER = 0x1,
  MMC_FILTER_NOVALUE = 0x8000
} MMC_FILTER_TYPE;

Constants

MMC_STRING_FILTER Value: 0 String filter.
MMC_INT_FILTER Value: 0x1 Integer filter.
MMC_FILTER_NOVALUE Value: 0x8000 When used by the IHeaderCtrl2::SetColumnFilter method, the snap-in sets the flag to clear the column filter. When used by the IHeaderCtrl2::GetColumnFilter method, the flag is set to indicate that the column filter is empty.

Remarks

The MMC_FILTER_NOVALUE enumerator value is not a filter type, but a flag that can be OR'd with a filter type. For example, to set a string type filter with no default value, you set the filter type to the following: MMC_STRING_FILTER | MMC_FILTER_NOVALUE.

When reading filter data, if no value has been entered by the snap-in or the user, the return type will be the filter type OR'd with MMC_FILTER_NOVALUE.
