一个Form里包含：一个Label1、一个Memo1、一个Edit、两个SpeedButton;代码写在A.cpp 
以下是A.cpp内容： 
//--------------------------------------------------------------------------- 

#include <vcl.h> 
#pragma hdrstop

} 
//--------------------------------------------------------------------------- 
//------------------按钮一----------------------------------------------------

void __fastcall TForm1::SpeedButton1Click(TObject *Sender) 
{ 
      int sn=0; 

          do 
            { 
              EditDZX->Text=Memo1->Lines->Strings[sn]; 
              EditDZX->SelStart=0;

              if(A==B||B==C||A==C) 
                {Memo1->Lines->Delete(sn);sn--;} 
              sn++; 
            }while(sn <Memo1->Lines->Count); 


      Label1->Caption="按钮1执行完毕！共 "+IntToStr(Memo1->Lines->Count)+" 行"; 
} 
//--------------------------------------------------------------------------- 
//-------------按钮二--------------------------------------------------------- 
//--------------------------------------------------------------------------- 
void __fastcall TForm1::SpeedButton2Click(TObject *Sender) 
{ 
      int sn=0; 

          do 
            { 
              EditDZX->Text=Memo1->Lines->Strings[sn]; 
              EditDZX->SelStart=0;

              if(A!=B&&B!=C&&A!=C) 
                {Memo1->Lines->Delete(sn);sn--;} 
              sn++; 
            }while(sn <Memo1->Lines->Count); 

      Label1->Caption="按钮2执行完毕！共 "+IntToStr(Memo1->Lines->Count)+" 行"; 
} 
//--------------------------------------------------------------------------- 
//--------------------------------------------------------------------------- 

以下是A.h内容： 
//--------------------------------------------------------------------------- 

#ifndef AH 
#define AH 
//--------------------------------------------------------------------------- 
#include <Classes.hpp> 
#include <Controls.hpp> 
#include <StdCtrls.hpp>

        __fastcall TForm1(TComponent* Owner); 
}; 
//--------------------------------------------------------------------------- 
extern PACKAGE TForm1 *Form1;

现在我要实现：把按钮一的代码放在A.cpp中，把按钮二的代码放在B.cpp中，该如何操作？
