windows - How to read from a text file using VBScript?

Question

I am looking to see a simple way to read from and write to a text file using VBScript.

I think this is an acceptable method for writing to a file.

 Dim f, 
 Dim fso

 Set fso = CreateObject("Scripting.FileSystemObject")
 Set f = fso.CreateTextFile("C:est.txt", True, True)

 f.WriteLine("Data to Add to file.")
 f.Close

However, I would like to know how to read from a file in a similar fashion.

Answer 1

Use first the method OpenTextFile, and then...

either read the file at once with the method ReadAll:

Set file = fso.OpenTextFile("C:est.txt", 1)
content = file.ReadAll

or line by line with the method ReadLine:

Set dict = CreateObject("Scripting.Dictionary")
Set file = fso.OpenTextFile ("c:est.txt", 1)
row = 0
Do Until file.AtEndOfStream
  line = file.Readline
  dict.Add row, line
  row = row + 1
Loop

file.Close

'Loop over it
For Each line in dict.Items
  WScript.Echo line
Next
