In Vietnam, many scientists have programed tidal analysis and prediction software in Pascal, Fortran, Java languages,... but have rarely publicied. In this paper, the authors present some results of application of the tidal prediction software, that is programed in Visual Basic language in Net environment of Visual Studio 2008 package. This software has applied in the tide table prediction and publication. It's graphic interface is convenient to look lip the information of hourly water levels, time or height of high and low water at 16 standard ports anrl some secondary ports. The software also allows to export the tidal prediction results of 16 standard ports directly to excel file, that is convenientfor the annual tide table publication.
