利用混合语言编程研制测量数据处理程序

MIXED LANGUAGE PROGRAMMING TO DEVELOP PROCESSING SOFTWARE OF SURVEYING DATA

FORTRAN适合于编制数值计算程序 ,但不易于编制菜单等用户界面。 VisualBasic的特点恰恰是易于编制用户界面。因此 Visual Basic和 FORTRAN的混合编程是许多程序员所关注的问题。本文详细介绍了如何用 Visual Basic和 FORTRAN混合编程研制测量数据处理程序 ,并以算例的形式给出了 WGS84坐标系下地心坐标转换到大地坐标 (XYZ→BLH)直接算法的源程序。

There are many surveying softwares made in FORTRAN because of its easy usage, but it is difficult to design menu and draw graphs. However it is easy to do so in Visual Basic.That is why so many programmers pay close attention to mixed language programming. This paper introduces in detail how to compile Visual Basic FORTRAN mixed language program.A source code example of coordinate transformation in WGS 84 system(XYZ→BLH) is given.
