IWbemQualifierSet::Put method (wbemcli.h)

  • Article

The IWbemQualifierSet::Put method writes the named qualifier and value. The new qualifier overwrites the previous value of the same name. If the qualifier does not exist, it is created.

Sometimes it is not possible to write the value of a qualifier, for example, if the qualifier is propagated from another object. Typically, propagated qualifiers are read-only, but they can be overridden. For more information, see Qualifier Flavors.

When using the Key qualifier, it is not necessary to specify any flavors or propagation rules.

The user may not create qualifiers with names that begin or end with an underscore (_). This is reserved for system classes and properties.

Syntax

HRESULT Put(
  [in] LPCWSTR wszName,
  [in] VARIANT *pVal,
  [in] long    lFlavor
);

Parameters

[in] wszName

Name of the qualifier that is being written. The pointer is treated as read-only.

[in] pVal

Cannot be NULL. This must point to a valid VARIANT that contains the qualifier value to be written. The pointer is treated as read-only. It is the caller's responsibility to call VariantClear on this pointer after the value is not required.

Only variants and arrays of type VT_I4, VT_R8, VT_BSTR, VT_BOOL are supported.

[in] lFlavor

Desired qualifier flavors for this qualifier. The following list lists the appropriate constants for lFlavor. The default value is zero (0).

WBEM_FLAVOR_OVERRIDABLE (0 (0x0))

The qualifier value can be overridden in a derived class or an instance. This is the default. Using this constant is the same as using the EnableOverride flag.

WBEM_FLAVOR_FLAG_PROPAGATE_TO_INSTANCE (1 (0x1))

The qualifier is propagated to instances. Using this constant is the same as using the ToInstance flag.

WBEM_FLAVOR_FLAG_PROPAGATE_TO_DERIVED_CLASS (2 (0x2))

The qualifier is propagated to derived classes. Using this constant is the same as using the ToSubClass flag.

WBEM_FLAVOR_NOT_OVERRIDABLE (16 (0x10))

The qualifier value cannot be overridden in a derived class or an instance. Using this constant is the same as using the DisableOverride flag.

WBEM_FLAVOR_AMENDED (128 (0x80))

The qualifier is localized. Using this constant is the same as using the Amended flag.

Return value

This method returns an HRESULT that indicates the status of the method call. The following list lists the value contained within an HRESULT.
