IConditionFactory2::ResolveCondition method (structuredquery.h)

Performs a variety of transformations on a condition tree, and thereby the resolved condition for evaluation. The returned object supports ICondition and ICondition2.

Syntax

HRESULT ResolveCondition(
  [in]           ICondition                      *pc,
  [in]           STRUCTURED_QUERY_RESOLVE_OPTION sqro,
  [in, optional] const SYSTEMTIME                *pstReferenceTime,
  [in]           REFIID                          riid,
  [out]          void                            **ppv
);

Parameters

[in] pc

Type: ICondition*

Pointer to an ICondition object to be resolved.

[in] sqro

Type: STRUCTURED_QUERY_RESOLVE_OPTION

Specifies zero or more of the STRUCTURED_QUERY_RESOLVE_OPTION flags. The SQRO_NULL_VALUE_TYPE_FOR_PLAIN_VALUES flag is automatically added to sqro.

[in, optional] pstReferenceTime

Type: SYSTEMTIME const*

Pointer to a SYSTEMTIME value to use as the reference date and time. A null pointer can be passed if sqro is set to the SQRO_DONT_RESOLVE_DATETIME flag.

[in] riid

Type: REFIID

The desired IID of the enumerating interface: either IEnumUnknown, IEnumVARIANT, or (for a negation condition) IID_ICondition.

[out] ppv

Type: void**

Receives a pointer to zero or more ICondition and ICondition2 objects.

Return value

Type: HRESULT

If this method succeeds, it returns S_OK. Otherwise, it returns an HRESULT error code.

Remarks

The StructuredQuerySample demonstrates how to read lines from the console, parse them using the system schema, and display the resulting condition trees.
