Hi guys,

I have a text file that has lines like these:

32/12/3312#__/__/____#__:__ __#__:__ __#1
31/23/123_#__/__/____#__:__ __#__:__ __#5
_3/12/312_#__/__/____#__:__ __#__:__ __#9

How can I read this file line by line?

Thanks.

Something like...

    Dim ff As Long
    Dim fileName As String
    Dim inputLine As String
   
    ff = FreeFile
    fileName = "c:\someFile.txt"
    Open fileName For Input As #ff
    While Not EOF(ff)
        Line Input #ff, inputLine
       
        ' do something with "inputLine"...
        Debug.Print inputLine
    Wend
    Close #ff

Dim fso As New FileSystemObject
Dim MyFile as File, inputLine$

Set MyFile = fso.OpenTextFile("c:\testfile.txt", ForReading)

While not MyFile.AtEndOfStream

   inputLine = MyFile.ReadLine

   Debug.Print inputLine

Wend

MyFile.Close

For JReam's code to work, you need a reference to the Scripting Runtime.  Click on Project --> References and check the "Microsoft Scripting Runtime" entry.

Then you need to change the declaration for the "MyFile" variable as it should be a "TextStream" and not a "File":

    Dim fso As New FileSystemObject
    Dim MyFile As TextStream
    Dim inputLine As String
   
    Set MyFile = fso.OpenTextFile(("c:\testfile.txt", ForReading)
    While Not MyFile.AtEndOfStream
        inputLine = MyFile.ReadLine
        Debug.Print inputLine
    Wend
    MyFile.Close

Hi RealSnaD,

Using JReam's approach, but no reference required:

    Dim fso As Object
    Dim MyFile As Object
    Dim inputLine As String
   
    Set fso = CreateObject("Scripting.FileSystemObject")
    Set MyFile = fso.OpenTextFile("c:\testfile.txt", ForReading)
    While Not MyFile.AtEndOfStream
        inputLine = MyFile.ReadLine
        Debug.Print inputLine
    Wend
    MyFile.Close

    Set MyFile = Nothing
    Set fso = Nothing

Regards,

Patrick
