Parametri

cCols
The number of columns in the buffer type definition.

rgCols
A pointer to the collection of DTP_BUFFCOL structures that describe each of the columns in the buffer type definition.

lMaxRows
The maximum number of rows that the buffer can hold.

dwCreationFlags
A combination of the values in the DTSBufferFlags.

Valore restituito

An unsigned integer that contains the ID of the buffer type.

Osservazioni

The buffer manager maintains a list of buffer types. Each buffer type definition contains the number of columns, the data type properties of each column, whether space is allocated that holds status information for the column, and how the columns are initialized when a new instance of the buffer type is created. This method is used to register a new buffer type with the manager. Once a buffer type has been defined, the returned ID of the buffer type is used when calling CreateBuffer. If a buffer definition is found that matches the parameters of this method, then its ID is returned. Otherwise, a new definition is created.

Thread Safety

Any public static (Shared in Microsoft Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
