没见过1楼的用法,换种方式试试:
http://www.foxtable.com/webhelp/topics/2492.htm
或者:http://foxtable.com/bbs/dispbbs.asp?BoardID=2&ID=107390&replyID=734188&skin=1
按方法1提升这样的错误

Dim Book As New XLS.Book("d:\问题\202405041636543400100 (2).xls")
Dim Sheet As XLS.Sheet = Book.Sheets(0)
For n As Integer = 1 To Sheet.Rows.Count - 1
Dim r As Row = Tables("表A").AddNew()
r("地市") = sheet(n, 0).Text
r("设备编码") = sheet(n, 3).Text
Dim s As String = ProjectPath & "Attachments\" & r("设备编码") & n & ".jpg"
If Sheet(n, 8).SaveImage(fl) Then '如果照片保存成功
dr("告警图片") = fileSys.GetName(fl)
End If
Next
用蓝版上面的代码可以解决导入问题,
但是又有新问题了,如果数据多,提示内存不足,怎样解决这个问题

处理图片一向都是很费内存的,可以拆分为几个文件处理
或者试试2楼第2种方法
