【dll问题】Undeclared identifier: 'Handle'怎么回事？

[xiaoxinpaigu]

我在写个dll文件，它显示我Wnd:=Handle;有错误，是不是少了哪个uses啊？请高手们指教，谢谢！


library Project1;

{ 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. }

我把 Wnd:=Handle; 改成 Wnd:=0;就OK了

你的handel哪来的呀，这不是在窗体里，可以直接调用self的handle
