Question

我正在尝试使用Do While Not EOF循环搜索某个字符串的txt文件，然后返回或只是在找到该字符串时设置该行号的标志。

我对VBA非常陌生，可以访问。这样做最基本的方法是什么？我正在使用Access 2007

谢谢

这是我到目前为止所做的，我从网上各种例子中提取它，试图让它发挥作用。

    Dim myFile As String
   Dim text As String
   Dim textline As String
   Dim posIAV As Integer

   myFile = "file path"

   Open myFile For Input As #1

   Do While Not EOF(1)
   Line Input #1, textline
   text = text & textline

   Loop

   Close #1

   posIAV = InStr(text, "IAVs ADDED in this release include")

   MsgBox (posIAV)

只需将下面的 MyString 替换为您正在寻找的任何内容。

   Dim myFile As String
   Dim text As String
   Dim textline As String
   Dim posIAV As Integer
   Dim Ctr as Integer
   Dim Ctr2 as Integer

   myFile = "file path"
   Ctr = 0
   Ctr2 = 0

   Open myFile For Input As #1

   Do While Not EOF(1)
   Line Input #1, textline
   text = text & textline

   ' Increment Ctr since you're on the line now
   Ctr = Ctr + 1

   ' Check the current line to see if it contains the string we're looking for
   ' If it does, set Ctr2 to be the current line number
   If textline like "*MyString*" Then
      Ctr2 = Ctr
   End If

   Loop

   Close #1

   posIAV = InStr(text, "IAVs ADDED in this release include")

   MsgBox (posIAV)

使用VBA在文本文件中搜索字符串并返回行号
