摘要
介绍了DLL的优越性和VB访问自定义数据结构方法,给出了具体的访问方案;并针对方案中的若干问题及原因进行了详细分析,最后给出了操作过程参考代码和实例.该方法应掌握的要点是:①VC中的DLL不同种类的应用差别;②DLL导出的函数约定;③VB数据类型和C/C++数据类型的对应关系;④VB和DLL之间不同类型参数的传递方法;⑤VB调用DLL的过程;⑥VB调用DLL的相关约定.
The advantage of DLL and the method to access the self-defined data structure with VB were introduced and the concrete scheme was described also. The problems and their reasons were analyzed in detail, and the example of process to operate and codes were presented. The keys to this method were as follows： （1）differences of DLLs in VC; （2）stipulation of DLL export functions; （3）relations between data types of VB and C/C＋＋; （4）ways to transfer different parameters between VB and DLL; （5）process of VB to call DLL; （6） relevant stipulation of VB to call DLL .
