  • Calls CheckBrowseMode to post any pending changes to a prior record if necessary.
  • Calls the BeforeDelete event handler.
  • Deletes the record.
  • Frees the buffers allocated for the record.
  • Puts the dataset into dsBrowse mode.
  • Resynchronizes the dataset to position the cursor on the next undeleted record.
