Based on the FORTRAN VLW code, a new visualized software was developed for calculating the detonation performance of explosives. The software was composed of a FORTRAN VLW core and a friendly user interface,which was built with VISUAL BASIC 6.0. The detonation parameters can be obtained by choosing some information about the calculated explosives,and browse and save these results given out in two types(graphic and document) conveniently.
