How to overwrite a file in VBScript [duplicate] - vbscript

i created a text file "list.txt" in commonapplicationdatafolder by using the following VBscript.i am displaying some
values from a variable(strlist) by writing in to textfile.
Const Value = &H23&
Const PATH = "\Cape\ibs"
Dim fso ' File System Object
Dim spFile ' Text File object to write
Dim objApplication ' Application object
Dim objFolder ' Folder object
Dim objFolderItem ' FolderItem object
Set objApplication = CreateObject("Shell.Application")
Set objFolder = objApplication.Namespace(Value)
Set objFolderItem = objFolder.Self
sname = objFolderItem.Path & PATH & "\list.txt"
Set fso = CreateObject("Scripting.FileSystemObject")
Set spFile = fso.CreateTextFile(sname, True)
spoFile.WriteLine(strlist)
spoFile.Close
Here are my doubts
1> Here before creating that file i need to delete the old existing "list.txt" Because during installation
i always want to create the list file. So i want to include code that removes any existing file(any old list.txt),
before creating the latest one.Here i did the following code
If fso.FileExists(sname) Then
fso.DeleteFile sname, True
Else
Set spFile = fso.CreateTextFile(sname, True)
spoFile.WriteLine(strlist)
Set objFolderItem = Nothing
Set objFolder = Nothing
Set objApplication = Nothing
Set fso = Nothing
spoFile.Close
End If
Whats going on is it will create folder first time,next time it will delete it ,But i always want that file there(new fresh one with value from 'strlist' )
Can any one tell me the vbscript code to do that.Their i removed Else part also but only deletion going ,below things are not working means creation.
2>Here i was writing in to "list.txt" by using simply 'WriteLine' method(spoFile.WriteLine(strlist)),but i read somewhere that we need to use
'OpenTextFile'(Const ForWriting = 2) for writing,If that is the case what changes i need to do here,Is it mandatory?

you need to move your delete or not delete decision before your write decision.
If fso.FileExists(sname) Then
'you delete if you find it'
fso.DeleteFile sname, True
End If
'you always write it anyway.'
Set spoFile = fso.CreateTextFile(sname, True)
spoFile.WriteLine(strlist)
Set objFolderItem = Nothing
Set objFolder = Nothing
Set objApplication = Nothing
Set fso = Nothing
spoFile.Close
alternately to your question with Constant write values and making this a little (very little) bit faster, you might try the following:
If fso.FileExists(sname) Then
Set spoFile = fso.OpenTextFile(sname, 2, True)
Else
Set spoFile = fso.CreateTextFile(sname, True)
End If
' perform your write operations and close normally'

' copy in flash drive
Const Removable = 1
Set FSO = CreateObject("Scripting.FileSystemObject")
Set colDrives = FSO.Drives
For Each Drive in colDrives
If Drive.DriveType = Removable then
fso.copyfile "filename.vbs" , Drive.DriveLetter&":\"
End if
Next

Outlook Redemption: Silent Import with ReceivedTime modification

Please help to automate the process which consists of 2 Subs:
Import - I need to make Silent import without target & destination folder selection dialog.
I need to import to my "INBOX/Imported" subfolder in Outlook and want to understand where in this code I can mention it explicitly.
I need to grab .EML files from the folder "D:\Emails" without redundant dialogue for folder selection:
Sub Redemp()
Dim objShell: Set objShell = CreateObject("Shell.Application")
Dim objFolder: Set objFolder = objShell.BrowseForFolder(0, "Select the folder containing eml-files", 0)
Dim Item
If (Not objFolder Is Nothing) Then
Set WShell = CreateObject("WScript.Shell")
Set objOutlook = CreateObject("Outlook.Application")
Set Folder = objOutlook.Session.PickFolder
If Not Folder Is Nothing Then
For Each Item In objFolder.Items
If Right(Item.name, 4) = ".eml" And Item.IsFolder = False Then
Set objPost = Folder.Items.Add(6)
Set objSafePost = CreateObject("Redemption.SafePostItem")
objSafePost.Item = objPost
objSafePost.Import Item.Path, 1024
objSafePost.MessageClass = "IPM.Note"
' remove IPM.Post icon
Set utils = CreateObject("Redemption.MAPIUtils")
PrIconIndex = &H10800003
utils.HrSetOneProp objSafePost, PrIconIndex, 256, True 'Also saves the message
End If
Next
End If
End If
MsgBox "Import completed.", 64, "Import EML"
Set objFolder = Nothing
Set objShell = Nothing
End Sub
Also, it would be great to avoid imported messages appearing in Outlook as if I already started replying to (not very convenient). If I use the above code and select imported message it doesn't look like originally received, but rather looks like text that I reply to.
I need to unify the below code that corrects ReceivedTime property of imported message (or it can modify EML file before import, sequence of actions is not important) with above import procedure.
Sub Redemp_sentreceived()
Set rSession = CreateObject("Redemption.RDOSession")
rSession.MAPIOBJECT = Application.Session.MAPIOBJECT
Set Msg = rSession.GetRDOObjectFromOutlookObject(Application.ActiveExplorer.CurrentFolder)
For Each Item In Msg.Items
Item.ReceivedTime = Item.SentOn
Item.Save
Next
End Sub
Ultimately imported .EML files should be in target folder with correct ReceivedTime.
Many thanks for helping me out in advance!
There is really no reason to use Safe*Item objects in this case - use RDOSession object, set the MAPIOBJECT property just like you do in the second example.
Off the top of my head:
Set rSession = CreateObject("Redemption.RDOSession")
rSession.MAPIOBJECT = Application.Session.MAPIOBJECT
Set folder = rSession.GetDefaultFolder(plFolderInbox).Folders.Items("Imported")
Set fileFolder = objFSO.GetFolder("D:\Emails")
For Each objFile in fileFolder.Files
set msg = folder.Items.Add("IPM.Note")
msg.Sent = true
msg.Import objFile.Path, 1031
msg.Save
Next
The problem was in number pointed in Import (I changed 1031 -> 1024) and now it works like a charm!
Sub MailImport()
Dim objFSO As Object
Set objFSO = CreateObject("Scripting.FileSystemObject")
Set rSession = CreateObject("Redemption.RDOSession")
rSession.MAPIOBJECT = Application.Session.MAPIOBJECT
Set Folder = rSession.GetDefaultFolder(olFolderInbox)
Set fileFolder = objFSO.GetFolder("D:\Emails")
For Each objFile In fileFolder.Files
Set msg = Folder.Items.Add("IPM.Note")
msg.sent = True
msg.Import objFile.Path, 1024
msg.ReceivedTime = msg.SentOn
msg.Save
objFile.Delete
Next
Set objFSO = Nothing
End Sub

Provide the source path

How can I take input as folder through GUI by using VBScript?
Example: I don't want to use following Window method.
Function Browse4Folder(strPrompt, intOptions, strRoot)
Dim objFolder, objFolderItem, objShell
Set objShell = CreateObject("Shell.Application")
Set objFolder = objShell.BrowseForFolder(0, strPrompt, intOptions, strRoot)
If (objFolder Is Nothing) Then
Browse4Folder = ""
Else
Set objFolderItem = objFolder.Self
Browse4Folder = objFolderItem.Path
Set objFolderItem = Nothing
Set objFolder = Nothing
End If
Set objShell = Nothing
End Function
I want to achieve the following:
I have a folder containing .h, .c, .exe, …
I have written the operation to removed unwanted files (like I required only .h file).
The end result should be only getting .h files.
All operation I have done but for statement (1), I have written the above snippet which provide the manual selection of the folder, but I want to make it automate (if I will run the script, all the operation should be complete without doing anything manually).
If I understand your question correctly, you want to remove all files from a given folder, except those with a specific extension (.h). That could be achieved with a procedure like this:
Sub DeleteExcept(path, extension)
Set fso = CreateObject("Scripting.FileSystemObject")
For Each f In fso.GetFolder(path).Files
If LCase(fso.GetExtensionName(f)) <> LCase(extension) Then f.Delete True
Next
End Sub
DeleteExcept "C:\your\folder" "h"

How to Copy a file that was read from a list

Hello guys I have an issue or issues with my code above
I'm trying to get "sExtension" to be search in a different folder other that the one I'm using to save my script since this script will be use as a Startup Script on many computers
(It works only if I run the script in the same folder "sExtension", "ExtAssign.txt" and sComputername are otherwise it wont find the path)
This is what it should do
Read a file called "ExtAssign.txt" (There is a full list of computer names in that file) and if it find the computer name on that file then it should copy a file with the with the extension number assigned to that computer name from a file server to "C:\" Drive
For this example I'm trying to do this locally, If I can make it then I'll try it from my File Server
Set objFSO = CreateObject("Scripting.FileSystemObject")
set oFso = CreateObject("Scripting.FileSystemObject")
Set objFS = CreateObject("Scripting.FileSystemObject")
Set fso = CreateObject("Scripting.FileSystemObject")
set oShell = WScript.CreateObject("WScript.Shell")
set oShellEnv = oShell.Environment("Process")
Set folder = Fso.GetFolder("C:\Users\XXXXX\Desktop\Test\Extensions\")
Set wshshell = CreateObject("WScript.Shell")
Set objNetwork = CreateObject("WScript.Network")
Set ObjEnv = WshShell.Environment("Process")
Set objFso = WScript.CreateObject("Scripting.FileSystemObject")
Scomputername = ObjEnv("COMPUTERNAME")
Set objFSO = CreateObject("Scripting.FileSystemObject")
set objWShell = wScript.createObject("WScript.Shell")
Dim strFile
'File to scan
strFile = "C:\Users\XXXXX\Desktop\Test\Extensions\Extassign\ExtAssign.txt"
Dim strPattern
'Look for computer name in file
strPattern = scomputername
Set objFso = WScript.CreateObject("Scripting.FileSystemObject")
Set objFile = objFS.OpenTextFile(strFile)
Do Until objFile.AtEndOfStream
Dim strLine
'Read each line and store it in strLine
strLine = objFile.ReadLine
'If the line matches the computer name, save the line to ExtArray
If InStr(strLine,strPattern)>0 Then
Dim ExtArray
'Split the line and separate the extension
ExtArray = Split(strLine,"|", -1, 1)
Dim sExtension
'Save the extension to sExtension
sExtension=ExtArray(1)
End If
Loop
'If the sExtension is empty, computer was not found, send message and terminate script.
If sExtension="" Then
WScript.Echo "ERROR: Computer "& scomputername &" not found in Extension Assignment List, so no extension has been set. Avaya will not be launched. Please contact your IT department for assistance."
Else
'If the sExtension contains a number, Copy that file to C:\ and rename it to Config.xml
fso.CopyFile "C:\Users\XXXXX\Desktop\Test\Extensions\ "& sExtension &"", "C:\Config.xml", True
End If
at the end it if it finds the file sExtension it will rename it to Config.xml but it wont do it unless I run the script in the same folder sExtension and sComputername.
I get File not found error
Thank you in advance and Happy new year!
The culprit is most likely this line:
fso.CopyFile "C:\Users\XXXXX\Desktop\Test\Extensions\ "& sExtension &"", "C:\Config.xml", True
There is a trailing space after the last backslash in the path, so you're creating a path
C:\Users\XXXXX\Desktop\Test\Extensions\ 12345
^
when you actually want a path
C:\Users\XXXXX\Desktop\Test\Extensions\12345
On a more general note: why are you creating 7(!) FileSystemObject instances (replacing one of them three times on top of that)? And 3(!) WScript.Shell instances? You don't even use most of them, not to mention that you don't need the Shell object in the first place. You only use it for determining the computer name, which could be done just fine using the WScript.Network object (that you don't use at all).
Also, please don't ever use comments like this:
'Read each line and store it in strLine
strLine = objFile.ReadLine
It's quite obvious that you read each line and assign it to the variable strLine. Comments shouldn't rephrase what you're doing (the code already does that, at least when you're using speaking variable and function names), but why you're doing it, i.e. what the purpose of a particular code section is.
Your code could be reduced to something as simple as this:
Set fso = CreateObject("Scripting.FileSystemObject")
Set net = CreateObject("WScript.Network")
computername = net.ComputerName
foldername = "C:\Users\XXXXX\Desktop\Test\Extensions"
filename = fso.BuildPath(foldername, "Extassign\ExtAssign.txt")
Set f = fso.OpenTextFile(filename)
Do Until f.AtEndOfStream
line = f.ReadLine
If InStr(line, computername) > 0 Then
arr = Split(line, "|", -1, 1)
If UBound(arr) >= 1 Then extension = arr(1)
End If
Loop
f.Close
If IsEmpty(extension) Then
WScript.Echo "ERROR: Computer "& computername &" not found in ..."
Else
fso.CopyFile fso.BuildPath(foldername, extension), "C:\Config.xml", True
End If

Check if folder is there, if not create it on current user logged in VBS

Currently this is my script
Set oWS = WScript.CreateObject("WScript.Shell")
' Get the %userprofile% in a variable, or else it won't be recognized
userProfile = oWS.ExpandEnvironmentStrings( "%userprofile%" )
What I am trying to do is grab the current user logged in, I want it to check the directory D:\"personsuser"\Appdata\Roaming\Local to see if the folder "Local" is created, if it isn't created I want to create one via createobject in vbs. The script above from what i know grabs the current logged on user, however i'm not sure how to use this variable to create a folder.
I know i will have to incorporate something along these lines:
Set objFSO = CreateObject("Scripting.FileSystemObject")
Set objFolder = objFSO.CreateFolder("C:\FSO")
And or something along these lines:
Dim objNetwork
Dim userName
Dim FSO
Set FSO = CreateObject("Scripting.FileSystemObject")
Set objNetwork = CreateObject("WScript.Network")
userName = objNetwork.userName
If fso.driveExists("D:\" & userName & "\AppData\Local\") Then
FSO.CreateDirectory ("D:\" & userName & "\AppData\Local\")
End If
Thanks in advance, not very familiar with VBS however that is the only platform I can operate from in the environment that i'm using it.
Set oWS = WScript.CreateObject("WScript.Shell")
' Get the %userprofile% in a variable, or else it won't be recognized
userProfile = oWS.ExpandEnvironmentStrings( "%userprofile%" )
Dim objNetwork
Dim userName
Dim FSO
Dim Folder
Set FSO = CreateObject("Scripting.FileSystemObject")
Set objNetwork = CreateObject("WScript.Network")
userName = objNetwork.userName
If NOT (FSO.FolderExists(userProfile + "\AppData\Roaming\Local")) Then
' Delete this if you don't want the MsgBox to show
MsgBox("Local folder doesn't exists, creating...")
splitString = Split(userProfile, "\")
' Create folder
MsgBox("D:\" + splitString(2) + "\AppData\Roaming\Local")
'FSO.CreateFolder(splitString(2) + "\AppData\Roaming\Local")
End If
Here you go man, this should work perfect, regards Daniel.
Here is code part from my utilty for FSO:
dim ffso
Function GetFSO
if not IsValidObject(ffso) then set ffso = CreateObject("Scripting.FileSystemObject")
Set GetFSO = ffso
End Function
sub SureDirectoryExists(ADir)
if ADir="" then exit sub
if not GetFSO().FolderExists(ADir) then
SureDirectoryExists ffso.GetParentFolderName(ADir)
ffso.CreateFolder ADir
end if
end sub
This function will create all folders in the path parameter (string).
Public Function CheckCreateFolder(path)
Dim TempPath As String
Dim FSO
Set FSO = CreateObject("Scripting.FileSystemObject")
pos = 0
While pos < Len(path)
pos = InStr(pos + 1, path, "\")
TempPath = Left(path, pos)
If Not (FSO.FolderExists(TempPath)) Then
FSO.CreateFolder (TempPath)
End If
Wend
End Function

Read and write into a file using VBScript

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 fso = CreateObject("Scripting.FileSystemObject" )
Set file = fso.OpenTextFile("C:\New\maddy.txt",1,1)
This opens the file only for reading but I am unable to write anything
and when I use this code:-
Set fso = CreateObject("Scripting.FileSystemObject" )
Set file = fso.OpenTextFile("C:\New\maddy.txt",2,1)
I can just use this file for writing but unable to read anything. Is there anyway by which we can open the file for reading and writing by just calling the OpenTextFile method only once.
I am really new to VBScript. I am only familiar with C concepts.
Is there any link to really get me started with VBScript?
I guess I need to have a good knowledge of the objects and properties concepts.
You can create a temp file, then rename it back to original file:
Set objFS = CreateObject("Scripting.FileSystemObject")
strFile = "c:\test\file.txt"
strTemp = "c:\test\temp.txt"
Set objFile = objFS.GetFile(strFile)
Set objOutFile = objFS.CreateTextFile(strTemp,True)
Set ts = objFile.OpenAsTextStream(1,-2)
Do Until ts.AtEndOfStream
strLine = ts.ReadLine
' do something with strLine
objOutFile.Write(strLine)
Loop
objOutFile.Close
ts.Close
objFS.DeleteFile(strFile)
objFS.MoveFile strTemp,strFile
Usage is almost the same using OpenTextFile:
Set objFS = CreateObject("Scripting.FileSystemObject")
strFile = "c:\test\file.txt"
strTemp = "c:\test\temp.txt"
Set objFile = objFS.OpenTextFile(strFile)
Set objOutFile = objFS.CreateTextFile(strTemp,True)
Do Until objFile.AtEndOfStream
strLine = objFile.ReadLine
' do something with strLine
objOutFile.Write(strLine & "kndfffffff")
Loop
objOutFile.Close
objFile.Close
objFS.DeleteFile(strFile)
objFS.MoveFile strTemp,strFile
Find more about the FileSystemObject object at http://msdn.microsoft.com/en-us/library/aa242706(v=vs.60).aspx. For good VBScript, I recommend:
Option Explicit to help detect typos in variables.
Function and Sub to improve readilbity and reuse
Const so that well known constants are given names
Here's some code to read and write text to a text file:
Option Explicit
Const fsoForReading = 1
Const fsoForWriting = 2
Function LoadStringFromFile(filename)
Dim fso, f
Set fso = CreateObject("Scripting.FileSystemObject")
Set f = fso.OpenTextFile(filename, fsoForReading)
LoadStringFromFile = f.ReadAll
f.Close
End Function
Sub SaveStringToFile(filename, text)
Dim fso, f
Set fso = CreateObject("Scripting.FileSystemObject")
Set f = fso.OpenTextFile(filename, fsoForWriting)
f.Write text
f.Close
End Sub
SaveStringToFile "f.txt", "Hello World" & vbCrLf
MsgBox LoadStringFromFile("f.txt")
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.
Don't think so...you can only use openTextFile for reading (1), writing (2), or appending (8). Reference here.
If you were using VB6 instead of VBScript, you could do:
Open "Filename" [For Mode] [AccessRestriction] [LockType] As #FileNumber
Using the Random mode. For example:
Open "C:\New\maddy.txt" For Random As #1
You could put it in an Excel sheet, idk if it'll be worth it for you if its needed for other things but storing info in excel sheets is a lot nicer because you can easily read and write at the same time with the
'this gives you an excel app
oExcel = CreateObject("Excel.Application")
'this opens a work book of your choice, just set "Target" to a filepath
oBook = oExcel.Workbooks.Open(Target)
'how to read
set readVar = oExcel.Cell(1,1).value
'how to write
oExcel.Cell(1,2).value = writeVar
'Saves & Closes Book then ends excel
oBook.Save
oBook.Close
oExcel.Quit
sorry if this answer isnt helpful, first time writing an answer and just thought this might be a nicer way for you
You could also read the entire file in, and store it in an array
Set filestreamIN = CreateObject("Scripting.FileSystemObject").OpenTextFile("C:\Test.txt",1)
file = Split(filestreamIN.ReadAll(), vbCrLf)
filestreamIN.Close()
Set filestreamIN = Nothing
Manipulate the array in any way you choose, and then write the array back to the file.
Set filestreamOUT = CreateObject("Scripting.FileSystemObject").OpenTextFile("C:\Test.txt",2,true)
for i = LBound(file) to UBound(file)
filestreamOUT.WriteLine(file(i))
Next
filestreamOUT.Close()
Set filestreamOUT = Nothing
Regardless of what you're trying to do there should be no need to read to and write to a file at the same time. It would also use more memory which should always be avoided. I'd suggest reading the entire file using the .ReadAll method and then close it and do whatever you need to do with the data (assuming you read the contents into a variable) and then do a write to the same file and overwrite the file. If you're concerned with having something go wrong when over-writing the current file you could always try to write it to a different file and throw an error if that doesn't work before trying to over-write the original.
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
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
