AddDateFilter Method of the IFPCFilterExpressions Interface

Syntax

HRESULT AddDateFilter(
  [in]  FpcFilterCriteria Criteria,
  [in]  FpcFilterCondition Condition,
  [in]  DATE Value,
		IFPCFilterExpression** ppNewFilterExpression
);

Parameters

Criteria

Value from the FpcFilterCriteria enumerated type that specifies the parameter (criteria) used in the filter expression.

When the FilterType property of the collection is set to fpcSessionsFilter, the only valid value for this parameter is fpcFilterByActivation.

When the FilterType property of the collection is set to fpcLogViewerFilter, the only valid value for this parameter is fpcFilterByLogTime.

Condition

Value from the FpcFilterCondition enumerated type that specifies the required relationship between the parameter (criteria) and the value included in the filter expression. The following values are valid:

• fpcLast24Hours
• fpcLast7days
• fpcLast30days
• fpcLastHour
• fpcLiveData
• fpcOnOrAfter
• fpcOnOrBefore

Value

Date literal that, together with the Criteria and Condition parameters, forms the filter expression. This parameter must always be set to a valid date literal, but it is only used if the Criteria parameter is set to fpcOnOrAfter or fpcOnOrBefore.

ppNewFilterExpression

Address of an interface pointer that on return points to the new IFPCFilterExpression interface created.

Return Value

This method can return one of the following:

• S_OK, indicating that the operation succeeded.
• An error code, indicating that the operation failed. In this case, the [out] parameter returned is a null object.

Syntax

Function AddDateFilter( _
  ByVal Criteria As FpcFilterCriteria, _
  ByVal Condition As FpcFilterCondition, _
  ByVal Value As Date _
) As FPCFilterExpression

Parameters

Criteria

Value from the FpcFilterCriteria enumerated type that specifies the parameter (criteria) used in the filter expression.

When the FilterType property of the collection is set to fpcSessionsFilter, the only valid value for this parameter is fpcFilterByActivation.

When the FilterType property of the collection is set to fpcLogViewerFilter, the only valid value for this parameter is fpcFilterByLogTime.

Condition

Value from the FpcFilterCondition enumerated type that specifies the required relationship between the parameter (criteria) and the value included in the filter expression. The following values are valid:

• fpcLast24Hours
• fpcLast7days
• fpcLast30days
• fpcLastHour
• fpcLiveData
• fpcOnOrAfter
• fpcOnOrBefore

Value

Date literal that, together with the Criteria and Condition parameters, forms the filter expression. This parameter must always be set to a valid date literal, but it is only used if the Criteria parameter is set to fpcOnOrAfter or fpcOnOrBefore.

Return Value

This method returns a reference to the FPCFilterExpression object if successful. Otherwise, an error is raised that can be intercepted by using an error handler.
