關於錯誤Access Violation和too many consecutive exceptions 解決方案

“如果DLL中用到了DELPHI的string類型，則DLL和主程式中都需要加上ShareMem”。DLL項目加ShareMem這個我知道，但主程式中也要加？這我就不明白了，為什麼以前不加的時候沒這個問題呢？加就加吧，果然加上後一點問題都沒有。唉，真是搞不明白。最後在建立DLL項目時，DELPHI有一段注釋給了我答案。

 

library MyDll;

 

{ 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. }

uses
  ShareMem,
  SysUtils,
  Controls,
  Forms;

{$R *.res}

 

begin

end.
