Application of Visual Basic and FORTRAN Mixed-language Programming to Visualization Technology for Hydro-meteorological Model

摘要

Combining graphical user interface in Visual Basic (VB) and numerical computing capability in FORTRAN, the hydro-meteorological model of the plain river network region was developed. This paper discussed some key problems, such as calling FORTRAN DLL from VB, FORTRAN compiling executable file called by VB, and the visualization platform development with VB and FORTRAN. It solved the problems of data processing, data transmission, and calling hydrological model. Mixed-language programming technique is a very effective and useful way of building visualization platform.
