Excel 파일이 백그라운드에서 실행 중이고 다른 Excel 파일에 액세스하는 동안 주 Excel 파일 데이터가 수신됩니다.

Question

코드에 오류가 없지만 Excel 파일이 붙어 있습니다. 나는 2 엑셀 파일을 사용했습니다, 하나는 abc30이고 다른 하나는 abc31입니다. abc30이 필터링되어 abc31으로 저장되었으므로 이제 abc31에 액세스하고 싶지만 다시 abc30 데이터가 여기에옵니다. 코드를 확인하고 문제를 알려주십시오.

그냥 숨겨지지 않은 세포를 확인 (또는 Range.SpecialCells (xlCellTypeVisible) 방법을 사용)해야한다. Easiest way to loop through a filtered list with VBA?
