Function SetUsageType ( _
    <InAttribute> lInputID As Integer, _
    <InAttribute> pIDTSVirtualInputObject As IDTSVirtualInput90, _
    <InAttribute> lLineageID As Integer, _
    <InAttribute> eUsageType As DTSUsageType _

[DispIdAttribute(16)] 
IDTSInputColumn90 SetUsageType (
    [InAttribute] int lInputID,
    [InAttribute] IDTSVirtualInput90 pIDTSVirtualInputObject,
    [InAttribute] int lLineageID,

/** @attribute DispIdAttribute(16) */ 
IDTSInputColumn90 SetUsageType (
    /** @attribute InAttribute() */ int lInputID, 
    /** @attribute InAttribute() */ IDTSVirtualInput90 pIDTSVirtualInputObject,

DispIdAttribute(16) 
function SetUsageType (
    lInputID : int, 
    pIDTSVirtualInputObject : IDTSVirtualInput90, 
    lLineageID : int, 
    eUsageType : DTSUsageType
) : IDTSInputColumn90

Parameters

lInputID
The ID of the IDTSInput90.

pIDTSVirtualInputObject
The IDTSVirtualInput90 object that contains the virtual input column and that is used to map the IDTSInputColumn90 object.

lLineageID
The LineageID property of the IDTSVirtualInputColumn90 object.

eUsageType
A value from the DTSUsageType enumeration that is assigned to the IDTSInputColumn90.

Return Value

The IDTSInputColumn90 object whose UsageType is set.

Remarks

SetUsageType is called when a column from the IDTSVirtualInputColumnCollection90 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 IDTSVirtualInputColumn90 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.
