Working with Files
I) Computer file System
In computing, a file system (often also written as filesystem) is a method for storing
and organizing computer files and the data they contain to make it easy to find and
access them. File systems may use a data storage device such as a hard disk or CD-
ROM.
II) Working with Drives and Folders
a) Creating a Folder
Option Explicit
Dim objFSO, objFolder, strDirectory
strDirectory = "D:logs"
Set objFSO = CreateObject("Scripting.FileSystemObject")
Set objFolder = objFSO.CreateFolder(strDirectory)
b) Deleting a Folder
Set oFSO = CreateObject("Scripting.FileSystemObject")
oFSO.DeleteFolder("E:FSO")
c) Copying Folders
Set oFSO=createobject("Scripting.Filesystemobject")
oFSO.CopyFolder "E:gcr6", "C:jvr", True
d) Checking weather the folder available or not, if not creating the folder
Option Explicit
Dim objFSO, objFolder, strDirectory
strDirectory = "D:logs"
Set objFSO = CreateObject("Scripting.FileSystemObject")
If objFSO.FolderExists(strDirectory) Then
Set objFolder = objFSO.GetFolder(strDirectory)
msgbox strDirectory & " already created "
else
Set objFolder = objFSO.CreateFolder(strDirectory)
end if
e) Returning a collection of Disk Drives
Set oFSO = CreateObject("Scripting.FileSystemObject")
Set colDrives = oFSO.Drives
For Each oDrive in colDrives
MsgBox "Drive letter: " & oDrive.DriveLetter
Next
f) Getting available space on a Disk Drive

Set oFSO = CreateObject("Scripting.FileSystemObject")
Set oDrive = oFSO.GetDrive("C:")
MsgBox "Available space: " & oDrive.AvailableSpace
III) Working with Flat Files
a) Creating a Flat File
Set objFSO = CreateObject("Scripting.FileSystemObject")
Set objFile = objFSO.CreateTextFile("E:ScriptLog.txt")
b) Checking weather the File is available or not, if not creating the File
strDirectory="E:"
strFile="Scripting.txt"
Set objFSO = CreateObject("Scripting.FileSystemObject")
If objFSO.FileExists(strDirectory & strFile) Then
Set objFolder = objFSO.GetFolder(strDirectory)
Else
Set objFile = objFSO.CreateTextFile("E:ScriptLog.txt")
End if
c) Reading Data character by character from a Flat File
Set objFSO = CreateObject("Scripting.FileSystemObject")
Set objFile = objFSO.OpenTextFile("E:gcr.txt", 1)
Do Until objFile.AtEndOfStream
strCharacters = objFile.Read(1)
msgbox strCharacters
Loop
d) Deleting Data From a Flat File
e) Comparing Flat Files
f) Searching Particular Strings in a Flat File
d) Reading Data line by line from a Flat File
Set objFSO = CreateObject("Scripting.FileSystemObject")
Set objFile = objFSO.OpenTextFile("E:gcr.txt", 1)
Do Until objFile.AtEndOfStream
strCharacters = objFile.Readline
msgbox strCharacters
Loop
e) Reading data from a flat file and using in data driven testing
Dim fso,myfile
Set fso=createobject("scripting.filesystemobject")
Set myfile= fso.opentextfile ("F:gcr.txt",1)
myfile.skipline
While myfile.atendofline <> True
x=myfile.readline
s=split (x, ",")

Dialog("Login").Activate
Dialog("Login").WinEdit("Agent Name:").Set s(0)
Dialog("Login").WinEdit("Password:").SetSecure s(1)
Dialog("Login").WinButton("OK").Click
Window("Flight Reservation").Close
Wend
f) Writing data to a text file
Dim Stuff, myFSO, WriteStuff, dateStamp
dateStamp = Date()
Stuff = "I am Preparing this script: " &dateStamp
Set myFSO = CreateObject("Scripting.FileSystemObject")
Set WriteStuff = myFSO.OpenTextFile("e:gcr.txt", 8, True)
WriteStuff.WriteLine(Stuff)
WriteStuff.Close
SET WriteStuff = NOTHING
SET myFSO = NOTHING
g) Delete a text file
Set objFSO=createobject("Scripting.filesystemobject")
Set txtFilepath = objFSO.GetFile("E:gcr.txt")
txtFilepath.Delete()
h) Checking weather the File is available or not, if available delete the File
strDirectory="E:"
strFile="gcr.txt"
Set objFSO = CreateObject("Scripting.FileSystemObject")
If objFSO.FileExists(strDirectory & strFile) Then
Set objFile = objFSO.Getfile(strDirectory & strFile)
objFile.delete ()
End if
i) Comparing two text files
Dim f1, f2
f1="e:gcr1.txt"
f2="e:gcr2.txt"
Public Function CompareFiles (FilePath1, FilePath2)
Dim FS, File1, File2
Set FS = CreateObject("Scripting.FileSystemObject")
If FS.GetFile(FilePath1).Size <> FS.GetFile(FilePath2).Size Then
CompareFiles = True
Exit Function

End If
Set File1 = FS.GetFile(FilePath1).OpenAsTextStream(1, 0)
Set File2 = FS.GetFile(FilePath2).OpenAsTextStream(1, 0)
CompareFiles = False
Do While File1.AtEndOfStream = False
Str1 = File1.Read
Str2 = File2.Read
CompareFiles = StrComp(Str1, Str2, 0)
If CompareFiles <> 0 Then
CompareFiles = True
Exit Do
End If
Loop
File1.Close()
File2.Close()
End Function
Call Comparefiles(f1,f2)
If CompareFiles(f1, f2) = False Then
MsgBox "Files are identical."
Else
MsgBox "Files are different."
End If
j) Counting the number of times a word appears in a file
sFileName="E:gcr.txt"
sString="gcreddy"
Const FOR_READING = 1
Dim oFso, oTxtFile, sReadTxt, oRegEx, oMatches
Set oFso = CreateObject("Scripting.FileSystemObject")
Set oTxtFile = oFso.OpenTextFile(sFileName, FOR_READING)
sReadTxt = oTxtFile.ReadAll
Set oRegEx = New RegExp
oRegEx.Pattern = sString
oRegEx.IgnoreCase = bIgnoreCase
oRegEx.Global = True
Set oMatches = oRegEx.Execute(sReadTxt)
MatchesFound = oMatches.Count
Set oTxtFile = Nothing : Set oFso = Nothing : Set oRegEx = Nothing
msgbox MatchesFound
IV) Working with Word Docs
a) Create a word document and enter some data & save
Dim objWD
Set objWD = CreateObject("Word.Application")
G.C.Reddy, QTP Trainer, Hyderabad (9247837478) 4
5. gcrindia@gmail.com
objWD.Documents.Add
objWD.Selection.TypeText "This is some text." & Chr(13) & "This is some more text"
objWD.ActiveDocument.SaveAs "e:gcreddy.doc"
objWD.Quit
V) Working with Excel Sheets
a) Create an excel sheet and enter a value into first cell
Dim objexcel
Set objExcel = createobject("Excel.application")
objexcel.Visible = True
objexcel.Workbooks.add
objexcel.Cells(1, 1).Value = "Testing"
objexcel.ActiveWorkbook.SaveAs("f:gcreddy1.xls")
objexcel.Quit
b) Compare two excel files
Set objExcel = CreateObject("Excel.Application")
objExcel.Visible = True
Set objWorkbook1= objExcel.Workbooks.Open("E:gcr1.xls")
Set objWorkbook2= objExcel.Workbooks.Open("E:gcr2.xls")
Set objWorksheet1= objWorkbook1.Worksheets(1)
Set objWorksheet2= objWorkbook2.Worksheets(1)
For Each cell In objWorksheet1.UsedRange
If cell.Value <> objWorksheet2.Range(cell.Address).Value Then
msgbox "value is different"
Else
msgbox "value is same"
End If
Next
objWorkbook1.close
objWorkbook2.close
objExcel.quit
set objExcel=nothing
