코드를 볼 수 없습니까? 그럼, 우리는 당신에게 답을 줄 수 없을 것입니다. –

해체를보고 올바르지 않은 주소를 해결하십시오. –

오류를 재생산하는 간단한 코드를 제공하는 것은 불가능할 수 있습니다. 적어도 응용 프로그램의 구조를 설명 할 수 있습니까? 스레드를 사용합니까? 귀하의 양식이 자동 생성되었거나 즉석에서 생성 되었습니까? 그런 것들은 이것을 디버깅하는 방법을 제안하는 약간의 도움을 줄 것입니다. –

최고입니다

0064e033 003 myprogram.exe로 Vcl.Controls TWinControl.HandleNeeded

당신은 정말 충분한 정보 프로그램을 구축해야한다

줄 번호 정보를 얻으려면 +003으로 충분합니다. TWinControl.HandleNeeded를 분해하며 다음과 같습니다

Vcl.Controls.pas.12079: begin 
005659FC 56    push esi 
005659FD 8BF0    mov esi,eax 
Vcl.Controls.pas.12080: if WindowHandle = 0 then 
005659FF 83BE7802000000 cmp dword ptr [esi+$00000278],$00 
00565A06 7516    jnz $00565a1e

주소가 프로그램에서 다를 수 있지만, 요점은 005659FF - 005659FC 오프셋 003 점이다. 그래서 예외는 함수의 첫 번째 줄에 있습니다

if WindowHandle = 0 then

유일한 메모리 액세스가 인스턴스 필드 WindowHandle을 읽을 수있는 시도가있다.

인스턴스 필드를 읽지 못하면 보통 인스턴스 포인터가 nil이거나 이미 삭제 된 인스턴스를 나타냅니다. 그리고 예외 텍스트는 상태 이후 :

Lesen 폰 ADRESSE 5AC03580

이 프로그램은 주소 5AC03580을 읽는 것을 알 수 있습니다. 0부터 먼 거리이므로 인스턴스 포인터는 nil이 아닙니다. 따라서 모든 표지판은 이미 파괴 된 인스턴스를 가리 킵니다.

파괴 된 인스턴스가있는 이유를 설명 할 방법이 없습니다. 이제 디버깅하는 것이 당신의 임무입니다. 그리고 여기 많은 애호가들처럼되지 말고 우리가 인간적으로 가능한 것 이상의 것을 말하기를 바랍니다. 가끔 질문에 대한 대답은 단순히 다음에 무엇을 해야할지 알려주는 것입니다.

이중 자유 시나리오를 디버깅하는 것은 미끄러 웠기 때문에 약간 까다로울 수 있습니다. 런타임 예외가 항상 발생하는 것은 아닙니다. FastMM과 같은 도구를 사용하여 이중 자유 오류를 감지하기위한 도구가 포함 된 전체 디버그 옵션을 사용하십시오.

Delphi 프로그램의 액세스 위반이 단서를 찾을 수 없습니다.
