안녕하세요.

데브기어 관리자님^^

다시 한번 더 질문을 드려 봅니다.

델파이7(window xp) 작업한 파일들(dll 포함)을 델파이xe5(window7 64bit)로 가져와서 마이그레이션 중에 있습니다.

로그인후 메인메뉴에 화면이 나옵니다.

현재 메인메뉴화면에서 A메뉴를 클릭하면 아래와 같은 에러가 나타납니다.
(클릭할려는 A메뉴부분 xe5에서 다시 컴파일한 DLL을 적용하였습니다.)

"Access Violation at address 0040B508 in module 'ATP2.exe'. Read of address 000003A8."

에러가 가리키는 부분은 uSubForm 소스상의 아래 부분인거 같은데 

function TfmASubForm.FindCommand(CommandName: String): TCommand;
begin
  
  Result:= CommandArray.FindCommand(CommandName);

  If Result = Nil
  Then Begin
       ErrorCode:= -3;
       // Command를 못찾더라도 Execute를 실행하는데 에러를 내지 않는다.  에러코드만 변경
       Result:= FNilCommand;
       End
  Else ErrorCode:= 0;
end;

제 생각에는 유니코드와 관련이 있는거 같은데 자료를 봐도 잘 모르겠습니다.
string 을 AnsiString, WideString로 변경해서 해봐도 같은 에러가 나옵니다.
원인을 못찾겠습니다. (많이 헤매고 있습니다. 도와주세요^^)

질문이 길더라도 끝까지 읽어봐주시고 답변 꼭 부탁드리겠습니다. ^^

  우선 메모리 참조에러가 발생합니다.

   

  아래와 같이 오류난 코드만 보면 frmSub가 없으면(nil) 오류가 나겠네요.

  frmMain.FindSubForm에서 찾지 못한 것 같습니다.

  그렇다면 왜 찾지 못하는지를 해결하면 되겠네요.

  코드 양이 많아 유니코드 문제인지는 잘 모르겠구요. 디버깅해보면 원인을 찾을 수 있을겁니다.

   

  showmessage('4 >' + _findDllForm); ---값 잘가져옴---

    fmSub := fmMain.FindSubForm(_findDllForm);
    
  showmessage('5 >'+_findDllForm); ---값 잘가져옴---

  showmessage('6 >'+_findModule);  ---값 잘가져옴---

    Command := fmSub.FindCommand('용영');  -- 여기서 에러가 납니다.---
