먼저 설정을 표시 할 양식을 만들었습니다. 그런 다음 ini 파일에서 비밀번호를로드하는 로그인 상자를 만들었습니다. 원래는 ini 파일을로드하는 것이 오류라고 생각했습니다. 비록 내가 설정 양식을로드 할 때 그것을 격리 시켰지만. 다음은 모두에 대한 코드입니다.양식을 변경하려고 할 때 프로그램 오류가 발생했습니다.

어디에서 Form1을 만드십니까? (BTW, 여러 구성 요소에 동일한 이벤트 처리기를 할당 할 수 있습니다.) –
실제 문제는 무엇입니까? –
로그인 버튼을 클릭하면 오류가 발생하고 CPU 오류 또는 무언가에 대해 프로그램이 중단됩니다. 그것은 degug 모드에서 붙어서 나는 프로그램을 다시 설정해야합니다. –
