Remarks
The columns in an IDTSBuffer100 contain metadata about the column data. This information is represented by the DTP_BUFFCOL structure. This structure is retrieved for an individual column by calling the GetColumnInfo method.
The values contained in the fields in the structure reflect the values contained in the IDTSOutputColumn100 that originally inserted the column into the data flow.
Thread Safety
Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
