BufferMode Property

  • Article

Specifies whether records are updated pessimistically or optimistically. Available at design time and run time.

Object.BufferMode[ = nValue]

Property Values

  • nValue
    The settings for the BufferMode property are:
    Setting Description
    0 (Default) None. Records are locked when editing begins and fields are written when the record pointer moves. Mimics FoxPro 2.x behavior.
    1 Pessimistic. Records are locked when editing begins and fields are written when the record pointer moves. You can use TABLEREVERT( ) to undo your changes to the current record.
    2 Optimistic. Records are not locked when edited and Visual FoxPro attempts to lock the records when they are written to disk with TABLEUPDATE( ).

Remarks

If BufferMode is set to 1 or 2, any cursor used by a Grid control is enabled for table buffering. Any other control bound to data uses row buffering.
