Design of Algorithms for Improvement of Delphi’s Controls DBGrid and DBNavigator

This paper is occupied with the improvement of three main functions of the preview of information from database in a table form: storage of changes or new entry in the table, delete of records from the table and sorting of information by clicking on the heading of column in the table information review. These improvements were obtained by occurrence coding connected t DBGrid. The accomplishment of these functions is regulated by the way that users of Windows applications accepted it as usual in that businesses, so the regulations of these applications which are programmed in Delphi improved its quality. Very important attribute of this paper is that the coding of algorithms have been done for using its procedures without a change, what creates the modularity of the source code.
