Osservazioni

The value is important for variable length types, such as DT_BYTES and DT_STR, because it determines the amount of storage available in the buffer for the column. The value does not include space for a trailing nullriferimento Null (Nothing in Visual Basic). terminator, though one is allocated and supplied by the buffer for DT_STR, DT_WSTR, and DT_TEXT types. For string types, the value is the number of characters. For fixed length and binary large object (BLOB) types, the lMaxLength value is ignored and contains a zero.
