문제는 먼저 2 색을 1 색으로 변환 한 다음 선택한 인덱스를 찾고 다시 변환 한 다음 새 인덱스를 저장해야한다는 것입니다. 그 후에 올바른 문자열을 표시하려면 올바른 string.format을 사용해야합니다. 그냥 혼란 스러워요 = (2 차원 배열을 1 차원으로 변환하려면 어떻게해야합니까?
"행"과 "열"크기를 묻는 두 개의 텍스트 상자가 있습니다
이 내 프로젝트 폴더입니까? 당신은 버튼과 목록 상자가

몇 가지 코드 예제를 게시하시기 바랍니다. 이 vb.net인가, 만약 내가 당신에게 vb.net 태그를 추가하는 것이 좋습니다 –
당신도 포맷을 수정하시기 바랍니다 수 있습니까? 다른 사람에 대해서는 잘 모릅니다. 그러나 1280 * 800 화면에서 그림을 그리는 시도가 전혀 작동하지 않습니다. 나는 여러분이 의미하는 것을 보여주기 위해 응용 프로그램의 스크린 샷을 찍거나 페인트 (또는 김프!)로 그림을 그리거나 다른 방법으로 StackOverflow의 서식 도구를 사용하는 것을 제안합니다. 다시 질문 할 수 있습니까? 변환, 찾기 및 변환이 필요한 이유는 무엇입니까? Ben이 말한 것처럼 코드를 게시하는 것이 좋은 첫 걸음이 될 것입니다. – Stephen
하지만 내 코드가 실패 롤? 좋아, 내 코드를 올리려고 노력할 것이지만, 그럴거야 =/ – HansEJC
