VBA Read a texts files: permission denied - vba

Question

I have a folder contain texts files . The text is presented as below :

and I want to write a vba code that read all the text files and search for an information "NAME" to replace it with "name"and then save the modifications .
I did the code below , but I have an error 70 permission denied in Set f = FSO.OpenTextFile(Fichier, forWriting, True) ,
could you help me ?
Sub Sample()
dim fso=createobject("scripting.filesystemObject")
dim f
dim path as string
dim file_txt as string
path= "C:\Users\Folder\Fileshere\"
file_txt= Dir(path & "*.*")
Do While Len(file_txt) > 0
'Set objfile = FSO.CreateTextFile(path & file_txt)
Set f = FSO.OpenTextFile(file_txt, ForReading)
While Not f.AtEndOfStream
Namechange = f.ReadAll
Wend
Namechange = Replace(Namechange , "NAME", "name")
Set f = FSO.OpenTextFile(file_txt, forWriting, True)
f.Write Namechange
file_txt=dir()
loop
end sub

Answer 1

I'd rewrite using a bit more of the FileSystemObject functionality rather than using Dir() personally, but that's open to your own choice. The key issue I think you are having is that you have opened the file for reading and then immediately tried to open it for writing while the TextStream object is still in memory, and locking the file. This is why you are getting "Permission denied". To quote from a TechNet Article:
Opening Text Files
Working with text files is a three-step process.
Before you can do anything else, you must open the text file. This can
be done either by opening an existing file or by creating a new text
file. (When you create a new file, that file is automatically opened
and ready for use.) Either approach returns a reference to the
TextStream object. After you have a reference to the TextStream
object, you can either read from or write to the file. However, you
cannot simultaneously read from and write to the same file. In other
words, you cannot open a file, read the contents, and then write
additional data to the file, all in the same operation. Instead, you
must read the contents, close the file, and then reopen and write the
additional data. When you open an existing text file, the file can be
opened either for reading or for writing. When you create a new text
file, the file is open only for writing, if for no other reason than
that there is no content to read. Finally, you should always close a
text file. Although this is not required (the file will generally be
closed as soon as the script terminates), it is good programming
practice.
My code should work for your requirements. I've removed the While loop from the middle as if you are using ReadAll then you don't need to loop over the text.
Sub MySub()
Dim fso
Set fso = CreateObject("scripting.filesystemObject")
Dim file, folder
Dim path As String
Dim file_txt As String
path = "C:\users\folders\fileshere\"
Set folder = fso.GetFolder(path)
For Each file In folder.Files
Set file = fso.OpenTextFile(file.Path, 1)
Namechange = file.ReadAll
file.Close
Namechange = Replace(Namechange, "NAME", "name")
Set file = fso.OpenTextFile(file.Path, 2, True)
file.Write Namechange
file.Close
Next
End Sub
If you have any difficulties or would like further explanation of the above, let me know.

Some minor changes and it worked for me. Please change the path as per your own requirement in following code:
Sub change_txt()
Dim fso As Object
Set fso = CreateObject("scripting.filesystemObject")
Dim f
Dim path As String
Dim file_txt As String
path = "D:\Folder\Fileshare\"
file_txt = Dir(path & "*.*")
Do While Len(file_txt) > 0
'Set objfile = FSO.CreateTextFile(path & file_txt)
Set f = fso.opentextfile(path & file_txt, 1)
While Not f.AtEndOfStream
Namechange = f.ReadAll
Wend
Namechange = Replace(Namechange, "NAME", "name")
Set f = fso.opentextfile(path & file_txt, 2)
f.Write Namechange
file_txt = Dir()
Loop
End Sub
