高分求救:如何将下列Delphi 代码转换成 VB代码啊，300分求助！！(300分)

{ Important note about DLL memory management: ShareMem must be the
first unit in your library's USES clause AND your project's (select
Project-View Source) USES clause if your DLL exports any procedures or
functions that pass strings as parameters or function results. This
applies to all strings passed to and from your DLL--even those that
are nested in records and classes. ShareMem is the interface unit to
the BORLNDMM.DLL shared memory manager, which must be deployed along
with your DLL. To avoid using BORLNDMM.DLL, pass string information
using PChar or ShortString parameters. }

晕

300块钱我估计没人干这事,呵呵,不是三句两句,不是问不明白的问题

这源码编译出来的是DLL，为什么还要改成VB？？VB里直接就可以调用嘛
