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.
