delphi 做了个DLL

library Project2; { 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 @R_425_4045@ion   using PChar or ShortString parameters. } uses   SysUtils,  Classes,  Dialogs; procedure teststr(); stdcall;   begin     showmessage('pxb');   end; {$R *.res}   exports     teststr; begin end.
