- lInputID
- Int32
The ID of the IDTSInput100.
- pIDTSVirtualInputObject
- IDTSVirtualInput100
The IDTSVirtualInput100 object that contains the virtual input column and that is used to map the IDTSInputColumn100 object.
- lLineageID
- Int32
The LineageID property of the IDTSVirtualInputColumn100 object.

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.
