)

[DispIdAttribute(16)]
IDTSInputColumn100^ SetUsageType(
    int lInputID,
    IDTSVirtualInput100^ pIDTSVirtualInputObject,
    int lLineageID,
    DTSUsageType eUsageType
)

[<DispIdAttribute(16)>]
abstract SetUsageType : 
        lInputID:int *
        pIDTSVirtualInputObject:IDTSVirtualInput100 *
        lLineageID:int *
        eUsageType:DTSUsageType -> IDTSInputColumn100

<DispIdAttribute(16)>
Function SetUsageType (
    lInputID As Integer,
    pIDTSVirtualInputObject As IDTSVirtualInput100,
    lLineageID As Integer,
    eUsageType As DTSUsageType
) As IDTSInputColumn100

Parameters

• lInputID
  Type: System.Int32

  The ID of the IDTSInput100.

• pIDTSVirtualInputObject
  Type: Microsoft.SqlServer.Dts.Pipeline.Wrapper.IDTSVirtualInput100

  The IDTSVirtualInput100 object that contains the virtual input column and that is used to map the IDTSInputColumn100 object.

• lLineageID
  Type: System.Int32

  The LineageID property of the IDTSVirtualInputColumn100 object.

• eUsageType
  Type: Microsoft.SqlServer.Dts.Pipeline.Wrapper.DTSUsageType

  A value from the DTSUsageType enumeration that is assigned to the IDTSInputColumn100.

Return Value

Type: Microsoft.SqlServer.Dts.Pipeline.Wrapper.IDTSInputColumn100

The IDTSInputColumn100 object whose UsageType is set.

Remarks

SetUsageType is called when a column from the IDTSVirtualInputColumnCollection100 is selected for a component. If the usageType is UT_READONLY or UT_READWRITE, a new input column is created for the component that reflects the IDTSVirtualInputColumn100 specified by the lLineageID parameter. If usageType is UT_IGNORED and the column exists in the collection, the column is removed and null is returned.
