TParam.SetData procedure
Set the parameter value from a buffer.
Declaration
procedure SetData(Buffer: Pointer)Arguments
Buffer | Buffer to read data from. |
Description
SetData performs the reverse operation of
GetData: it reads the parameter value from the memory
area pointed to by
Buffer. The size of the data read is determined by
GetDataSize and the
type of data by
DataType : it is the same storage mechanism used by
TField, and so can be used to copy
the value from a
TDataset record buffer.Errors
Not all field types are supported. If an unsupported field type is encountered, an EDatabaseError exception is raised.
