The WMDM_PROP_DESC structure describes valid values of a property in a particular property configuration.

Syntax

typedef struct _WMDM_PROP_DESC{LPWSTR  pwszPropName;WMDM_ENUM_PROP_VALID_VALUES_FORM  ValidValuesForm;[switch_type(WMDM_ENUM_PROP_VALID_VALUES_FORM)] [switch_is(ValidValuesForm)]  union {    [case (WMDM_ENUM_PROP_VALID_VALUES_ANY)];    [case (WMDM_ENUM_PROP_VALID_VALUES_RANGE)]        WMDM_PROP_VALUES_RANGE ValidValuesRange;
    [case (WMDM_ENUM_PROP_VALID_VALUES_ENUM)]        WMDM_PROP_VALUES_ENUM EnumeratedValidValues;
  } ValidValues
} WMDM_PROP_DESC;

Members

pwszPropName

Name of the property. The application must free this memory when it is done using it.

ValidValuesForm

An WMDM_ENUM_PROP_VALID_VALUES_FORM enumeration value describing the type of values, such as a range or list. The value of this enumeration determines which member variable is used.

ValidValues

Holds the valid values of the property in a particular property configuration. This member holds one of three items: the enumeration value WMDM_ENUM_PROP_VALID_VALUES_ANY; the member ValidValuesRange; or the member EnumeratedValidValues. The value or member is indicated by ValidValuesForm.

ValidValuesRange

A WMDM_PROP_VALUES_RANGE structure containing a range of valid values. This is present only when ValidValuesForm is set to WMDM_ENUM_PROP_VALID_VALUES_RANGE. See Remarks.

EnumeratedValidValues

A WMDM_PROP_VALUES_ENUM structure containing an enumerated set of valid values. This is present only when ValidValuesForm is set to WMDM_ENUM_PROP_VALID_VALUES_ENUM. See Remarks.

Remarks

The WMDM_PROP_DESC structure contains a property description that consists of a property name and its valid values in a particular configuration.

The caller is required to free the memory used by ValidValuesRange or EnumeratedValues. For an example of how to do this, see WMDM_FORMAT_CAPABILITY.
