            Next
            nr("上传时间") = DateTime.Now
            nr.Save
            o = o + 1
        Else
            MessageBox.Show("D")
            For p As Integer = 0 To tCols.Length -1

            Next
            fr("上传时间") = DateTime.Now
            fr.Save
            f = f + 1
        End If
        i = i + 1
        prb.Value = i
        dr("是否上传") = True
        dr.save
    End If
Next
MessageBox.Show("体温数据已上传,其中新数据" & o & "个,覆盖原数据" & f & "个","温馨提示")

修改了还是一样，另外若执行这一段代码的时候是没有问题，
