Hinweise

The columns in an IDTSBuffer100 contain metadata about the column data. This information is represented by the tagBUFFERCOL structure. This structure is retrieved for an individual column by calling the GetColumnInfo method.

The values contained in the fields within the structure reflect the values contained in the IDTSOutputColumn100 that originally inserted the column into the data flow.

Hinweis
The tagBUFFERCOL structure is also represented by the DTP_BUFFCOL and BufferColumn structures. The DTP_BUFFCOL structure is a C++ type definition. When writing managed code, you will use the BufferColumn structure.

Threadsicherheit

Alle öffentlichen static (Shared in Visual Basic)-Elemente dieses Typs sind Threadsicher. Für Instanzelemente wird die Threadsicherheit nicht gewährleistet.
