TField.SetData procedure
Save the field data.
Declaration
procedure SetData(Buffer: Pointer); overload
procedure SetData(Buffer: Pointer; NativeFormat: Boolean); overloadArguments
Buffer | Buffer to copy field value from. |
NativeFormat | Is the provided data in native format. |
Description
SetData saves the value of the field data in
Buffer to the dataset internal buffer.
The
Buffer pointer should point to a memory buffer containing the data for the field in the correct format.
If the
NativeFormat parameter is true, then date/time formats should use
the
TDateTime format.
There should normally not be any need to call SetData directly: it is called by the various setter methods of the AsXXX properties of TField.
Errors
No validity checks are performed on
Buffer: it should point to a valid memory area, and should be large enough to contain the value of the field.
Failure to provide a buffer that matches these criteria will result in an exception.
