摘　　要：为解决Fortran与VB经由Win32 DLL开展的混合工程计算的异步通信问题,研究了Fortran Win32 DLL对VB窗体的回调,基于对函数指针的本质认识,揭示了Win32 API函数的回调机制。通过挖掘Fortran 90新增功能,给出了Fortran Win32DLL独特的回调手段,在此基础上,利用VB新增对函数指针的支持,成功实施了Fortran Win32 DLL对VB窗体的回调,对字符串特殊参数给出了具体的处理办法。探讨结果表明,Fortran90创建的Win32DLL能够拥有回调能力,可以作为便捷的异步通信手段开展科学计算可视化的交互视算。To implement asynchronous communication in computation of Fortran/VB mixed-language programming engineering with Win32 DLL,it is researched for Fortran Win32 DLL to invoke VB forms by callback.According to natural recognition of function pointers,the callback of Win32 API functions is revealed.A particular callback approach of Fortran Win32 DLL is proposed by mining on the new characteristics of Fortran 90.On this basis,having taken advantage of VB supporting function pointers,it is solved for Fortran Win32 DLL to invoke VB forms by callback.For especial string arguments,their passing ways are presented.It has been proved that Fortran Win32 DLL is able to trigger a callback,a convenient asynchronous communication way is performed by which steering computation in scientifically computing visualization.
