Syntax
typedef enum tagREG_COMPARISONTYPE {
REG_CT_ANYCHANGE,
REG_CT_EQUAL,
REG_CT_NOT_EQUAL,
REG_CT_GREATER,
REG_CT_GREATER_OR_EQUAL,
REG_CT_LESS,
REG_CT_LESS_OR_EQUAL,
REG_CT_CONTAINS,
REG_CT_STARTS_WITH,
REG_CT_ENDS_WITH
} REG_COMPARISONTYPE;
Elements
- REG_CT_ANYCHANGE
Notify on any change.
- REG_CT_EQUAL
Registry values are equal.
- REG_CT_NOT_EQUAL
Registry values are not equal.
- REG_CT_GREATER
Registry value is greater than the target value.
- REG_CT_GREATER_OR_EQUAL
Registry value is greater than or equal to the target value.
- REG_CT_LESS
Registry value is less than the target value.
- REG_CT_LESS_OR_EQUAL
Registry value is less than or equal to the target value.
- REG_CT_CONTAINS
State property value contains the target value string.
- REG_CT_STARTS_WITH
State property value starts with the target value string.
- REG_CT_ENDS_WITH
State property value ends with the target value string.
Remarks
Certain enumeration values are valid only for certain data types. The following table shows which enumeration values are valid for each registry value type.
