我有一个自动打开的excel文件，然后它运行一个宏。此宏从 txt 文件导入数据。每 1 小时，数据进入 txt 文件的新行（时间戳和值）。我的宏在下午 5 点打开，导入数据，绘制图表，将其保存到动态日期，然后关闭。

这个宏每天下午 5 点打开一次。但是，我不希望宏在第一天继续选择前 24 行，在第二天继续选择后 24 行。当它在第二天运行时。第二天，我只想选择行（25-49）。第三天，我想选择行（50-74）。

有没有人有使用相同宏动态选择行的方法？

读取内存中的文件，而不是将其放入电子表格中：

dFirstDate = #10/1/2013#
dDate = Now
nDays = DateDiff("d", dDate, dFirstDate)
nRowStart = nDays * 24
sFile = "C:\Users\Pablo\Desktop\LOGTEST.txt"
Open sFile For Input As iFileNum
Line Input #iFileNum, sBuf
While Not sBuf = "" And Len(sBuf) > 1
    nFileRow = nFileRow + 1
    If nFileRow >= nRowStart And nFileRow <= nRowStart + 24 Then
        ActiveSheet.Range("A1").Offset(nSheetRow, 0).Value = sBuf
        nSheetRow = sSheetRow + 1
    End If
    Line Input #iFileNum, sBuf
Wend
Close #iFileNum
