应用程序初始化失败

[zhangzii]

本人照书上的例子作一个鼠标钩子，可是一点击运行，出现“应用程序正常初始化失败”，百思不得其解啊，搜索俩论坛也没有相关内容，请大家帮忙看下，源代码如下
library hook;

{ 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. }
