Question

How can we read and write some string into a text file using VBScript? I mean I have a text file which is already present so when I use this code below:-

Set         


        

Answer 1

This is for create a text file

For i = 1 to 10
    createFile( i )
Next

Public Sub createFile(a)

    Dim fso,MyFile
    filePath = "C:\file_name" & a & ".txt"
    Set fso = CreateObject("Scripting.FileSystemObject")
    Set MyFile = fso.CreateTextFile(filePath)
    MyFile.WriteLine("This is a separate file")
    MyFile.close

End Sub

And this for read a text file

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

file.Close

For Each line in dict.Items
  WScript.Echo line
  WScript.Sleep 1000
Next

Below is some simple code to execute this:

sLocation = "D:\Excel-Fso.xls"
sTxtLocation = "D:\Excel-Fso.txt"
Set ObjExl = CreateObject("Excel.Application")
Set ObjWrkBk = ObjExl.Workbooks.Open(sLocation)
Set ObjWrkSht = ObjWrkBk.workSheets("Sheet1")
ObjExl.Visible = True
Set FSO = CreateObject("Scripting.FileSystemObject")
Set FSOFile = FSO.CreateTextFile (sTxtLocation)
sRowCnt = ObjWrkSht.usedRange.Rows.Count
sColCnt = ObjWrkSht.usedRange.Columns.Count
For iLoop = 1 to sRowCnt
  For jLoop = 1 to sColCnt 
    FSOFile.Write(ObjExl.Cells(iLoop,jLoop).value) & vbtab 
  Next
Next

Set ObjWrkBk = Nothing
Set ObjWrkSht = Nothing
Set ObjExl = Nothing
Set FSO = Nothing
Set FSOFile = Nothing

Answer 3

You could open two textstreams, one for reading

Set filestreamIn = CreateObject("Scripting.FileSystemObject").OpenTextFile("C:\Test.txt,1)

and one for appending

Set filestreamOUT = CreateObject("Scripting.FileSystemObject").OpenTextFile("C:\Test.txt,8,true)

The filestreamIN can read from the begining of the file, and the filestreamOUT can write to the end of the file.
