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:\test.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.
Use first the method OpenTextFile, and then...
either read the file at once with the method ReadAll:
Set file = fso.OpenTextFile("C:\test.txt", 1)
content = file.ReadAll
or line by line with the method ReadLine:
Set dict = CreateObject("Scripting.Dictionary")
Set file = fso.OpenTextFile ("c:\test.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
Dim obj : Set obj = CreateObject("Scripting.FileSystemObject")
Dim outFile : Set outFile = obj.CreateTextFile("in.txt")
Dim inFile: Set inFile = obj.OpenTextFile("out.txt")
' Read file
Dim strRetVal : strRetVal = inFile.ReadAll
inFile.Close
' Write file
outFile.write (strRetVal)
outFile.Close
