I would like to append a text (.txt) file backwards is this possible?
By backwards I mean writing text from bottom to top rather then the standards top to bottom.
Why because the txt file I want to compile is read so that items at the top of the list are given priority to those at the bottom.
I can't think of any other way than to create a new file whenver you want to insert data at the top and then delete/rename the old one and rename the new file to the new one.
Not sure exactly your requirements BUT the easiest way in VBA is to
1. Add a reference to the Microsoft Scripting Runtime.
Public Sub Reverse()
Dim lReverseString As String
Dim lFSO As FileSystemObject
Set lFSO = New Scripting.FileSystemObject
With lFSO.OpenTextFile("SourceName", ForReading)
While Not .AtEndOfStream
' Note if you are looking to read a line at at a time use .ReadLine Instead of .Read
lReverseString = .Read & lReverseString
Wend
End With
' now you have a string in reverse
With lFSO.CreateTextFile("TargetName", True, False)
.Write lReverseString
.Close
End With
End Sub
This is a basic form which should get you going.
How about an array? It would not be suitable with a very large file:
Dim fs As Object
Dim ts As Object
Dim AllTextArray As Variant
''Late binding, no reference required
Set fs = CreateObject("Scripting.FileSystemObject")
''ForReading=1
Set ts = fs.OpenTextFile("c:\docs\BookX.csv", 1)
AllTextArray = Split(ts.ReadAll, vbCrLf)
For i = UBound(AllTextArray) To 0 Step -1
Debug.Print AllTextArray(i)
Next
If it's just writing each paragraph or sentence in the reverse order than it appears:
Sub Test()
Dim currentDocument As Document
Set currentDocument = ActiveDocument
Dim sourceDocument As Document
Set sourceDocument = Documents.Add("c:\words.txt")
Dim i As Long
For i = sourceDocument.Paragraphs.Count To 1 Step -1
currentDocument.Range.InsertAfter sourceDocument.Paragraphs(i).Range.Text
DoEvents
Next
sourceDocument.Close wdDoNotSaveChanges
End Sub

In my never ending story to learn VBA I am trying to create a macro that deletes files based on the files starting characters and unsure how to proceed.
I have an excel file with numbers in column a ,these numbers are either 4,5 or 6 digits.
I have a file folder with files which may or may not start with these digits from a range from excel file. These files in folders are of different types
But I reckon this may not be an issue still,the naming convention is as follows : ie. 4563_listofitems.pdf,65475_skusdec.doc etc.
My goal is to loop through files and check if the starting characters of the file are on included in the A range of the excel sheet,if so (there may be up to 6 files starting with such number) create a folder named with the found starting characters and move the files starting with these characters into the folder,else if file doesn't start with fixed characters from the list then just delete (kill) that file. My issue is idk how to check the files names against the list.
My code as now for looping trough
Sub loopf
Dim filen as variant
Filen =dir("c:\test\")
While filen <>""
If instr(1,filen,10000)=1 then
'Here I want check against the values from range but unsure how ,should I somehow loop through the range ?
Filen=dir
End if
Wend
End sub
To check if a value is contained within a known list, I like using the Dictionary Object. It has the function Exists which checks if a value is listed within the Dictionary.
So before you loop through the files, you just need to add every one of your accepted numbers into the dictionary. Then while looping though the files check if Dictionary.Exists(Value). If it exists, then the value is good, if not then Kill.
Here's how I would set that up:
Sub loopf()
Dim AcceptedPrefixes As Object
Set AcceptedPrefixes = CreateObject("Scripting.Dictionary")
Dim PrefixRange As Range
Set PrefixRange = ThisWorkbook.Sheets(1).Range("A1:A5")
Dim Cell As Range
For Each Cell In PrefixRange.Cells
If Cell <> "" And Not AcceptedPrefixes.exists(Cell.Value) Then
AcceptedPrefixes.Add CStr(Cell.Value), 0
End If
Next
Dim Directory As String
Directory = "c:\test\"
Dim filen As Variant
filen = Dir(Directory)
While filen <> ""
Dim FilePrefix As String
FilePrefix = Split(filen, "_")(0)
If Not AcceptedPrefixes.exists(FilePrefix) Then
Kill Directory & filen
End If
filen = Dir
Wend
End Sub
Sub Files()
Dim oFSO As Object
Dim oFolder As Object
Dim oFile As Object
Dim i As Integer
Set oFSO = CreateObject("Scripting.FileSystemObject")
Set oFolder = oFSO.GetFolder("C:\test")
For Each oFile In oFolder.Files
'do somthing
Next oFile
End Sub
I have following vba code which write items in the ArrayList to file with TextStream.
Sub WriteListAsCSV(list As Object, filePath As String)
Dim fso As New FileSystemObject
Dim ts As TextStream
Set ts = fso.CreateTextFile(filePath, True)
Dim line As Variant
For Each line In list
ts.WriteLine (line)
Next line
ts.Close
End Sub
Problem is I'm getting extra linebreak at the end of the file.
I can do like following but I don't want to check at each loop for that single linebreak.
Sub WriteListAsCSV(list As Object, filePath As String)
Dim fso As New FileSystemObject
Dim ts As TextStream
Set ts = fso.CreateTextFile(filePath, True)
Dim line As Variant
Dim i As Integer
For i = 0 To list.Count
line = list(i)
ts.Write (line)
'If not last line
If Not i = list.Count Then
'Write blankline
ts.WriteLine()
End If
Next
ts.Close
End Sub
Is there any way to remove one character back like Backspace button in VBA? Or another neat trick to do this?
Idea
My idea was to remove the last charaters corresponding to the linebreak, which are Chr(10) or Chr(13) and sometimes both, using the file length.
How to do
While I was checking about how to use a function I found this: Remove last carriage return file which covers exactly my idea ... Maybe have a look it's pretty clear.
EDIT (cf # Siddharth Rout comment)
Modified and commented version of the code (In case of the link dies. I take no credit for this code)
Set objFSO = CreateObject("Scripting.FileSystemObject")
Set objFile = objFSO.OpenTextFile("path\to\file", 1) ' -- 1:read
strFile = objFile.ReadAll
objFile.Close
' We check if the two last characters correspond to a linebreak:
If Right(strFile, 2) = vbCrLf Then
' If so, we remove those charaters:
strFile = Left(strFile, Len(strFile)- 2)
Set objFile = objFSO.OpenTextFile("path\to\file", 2) ' -- 2:write
objFile.Write strFile
objFile.Close
End If
I'm not sure it's the more elegant way to do but it seems to be a pretty valid one. Hope this works for you.
There are a number of similar posts but nothing that does exactly what I want as simply as it needs to be for me to understand
I want to use Access 2007 VBA to open a csv file and replace the column headings row ie:
OldColumn1,OldColumn2
1,2
with
NewColumn1,NewColumn2
1,2
ie without disturbing the rump of data.
Then save and close.
I have tried this code, but it deletes my data:
Sub WriteFile()
Dim OutputFileNum As Integer
Dim PathName As String
PathName = Application.ActiveWorkbook.Path
OutputFileNum = FreeFile
Open PathName & "\Test.csv" For Output Lock Write As #OutputFileNum
Print #OutputFileNum, "NewCol1" & "," & "NewCol2"
Close OutputFileNum
End Sub
Import or link to the .csv so that you have the recordset in your Access 2007 databases.
Write a query with NewColumn[x] as an alias for OldColumn[x].
Write vba code to use TransferText functionality or make a macro to do the same to export your query as a .csv file (overwriting the original csv if you want/need).
Obviously, there are plenty of bonus things you could do to automate and reproduce this concept for any number or types of files. But the above solution should work in an all MS Access environment.
Let me know if you would like details on any of these steps.
Further to my earlier comment, please see the method which uses the Excel reference:
Public Sub EditCsv()
Dim xlApp As Object
dim xlWbk As Object
Dim xlWst As Object
Set xlApp = CreateObject("Excel.Application")
Set xlWbk = xlApp.Workbooks.Open ".../Test.csv" 'Amend this to your needs
Set xlWst = xlWbk.Sheets(1)
'This assumes the columns are at the beginning of the file
xlWst.Range("A1") = "My New Column Name"
xlWst.Range("B1") = "My New Second Column Name"
xlWbk.Close -1 'Close and save the file here
xlApp.Quit
Set xlApp = Nothing
Set xlWbk = Nothing
Set xlWst = Nothing
End Sub
Using VBA. My script moves a file into a directory. If that filename already exists in the target directory, I want the user to be prompted to rename the source file (the one that's being moved) before the move is executed.
Because I want the user to know what other files are in the directory already (so they don't choose the name of another file that's already there), my idea is to open a FileDialog box listing the contents of the directory, so that the user can use the FileDialog box's native renaming capability. Then I'll loop that FileDialog until the source file and target file names are no longer the same.
Here's some sample code:
Sub testMoveFile()
Dim fso As FileSystemObject
Dim file1 As File
Dim file2 As File
Dim dialog As FileDialog
Set fso = New FileSystemObject
fso.CreateFolder "c:\dir1"
fso.CreateFolder "c:\dir2"
fso.CreateTextFile "c:\dir1\test.txt"
fso.CreateTextFile "c:\dir2\test.txt"
Set file1 = fso.GetFile("c:\dir1\test.txt")
Set file2 = fso.GetFile("c:\dir2\test.txt")
Set dialog = Application.FileDialog(msoFileDialogOpen)
While file1.Name = file2.Name
dialog.InitialFileName = fso.GetParentFolderName(file2.Path)
If dialog.Show = 0 Then
Exit Sub
End If
Wend
file1.Move "c:\dir2\" & file1.Name
End Sub
But when I rename file2 and click 'OK', I get an error:
Run-time error '53': File not found
and then going into the debugger shows that the value of file2.name is <File not found>.
I'm not sure what's happening here--is the object reference being lost once the file's renamed? Is there an easier way to let the user rename from a dialog that shows all files in the target directory? I'd also like to provide a default new name for the file, but I can't see how I'd do that using this method.
edit: at this point I'm looking into making a UserForm with a listbox that gets populated w/ the relevant filenames, and an input box with a default value for entering the new name. Still not sure how to hold onto the object reference once the file gets renamed, though.
Here's a sample of using Application.FileDialog to return a filename that the user selected. Maybe it will help, as it demonstrates getting the value the user provided.
EDIT: Modified to be a "Save As" dialog instead of "File Open" dialog.
Sub TestFileDialog()
Dim Dlg As FileDialog
Set Dlg = Application.FileDialog(msoFileDialogSaveAs)
Dlg.InitialFileName = "D:\Temp\Testing.txt" ' Set suggested name for user
' This could be your "File2"
If Dlg.Show = -1 Then
Dim s As String
s = Dlg.SelectedItems.Item(1) ` Note that this is for single-selections!
Else
s = "No selection"
End If
MsgBox s
End Sub
Edit two: Based on comments, I cobbled together a sample that appears to do exactly what you want. You'll need to modify the variable assignments, of course, unless you're wanting to copy the same file from "D:\Temp" to "D:\Temp\Backup" over and over. :)
Sub TestFileMove()
Dim fso As FileSystemObject
Dim SourceFolder As String
Dim DestFolder As String
Dim SourceFile As String
Dim DestFile As String
Set fso = New FileSystemObject
SourceFolder = "D:\Temp\"
DestFolder = "D:\Temp\Backup\"
SourceFile = "test.txt"
Set InFile = fso.GetFile(SourceFolder & SourceFile)
DestFile = DestFolder & SourceFile
If fso.FileExists(DestFile) Then
Dim Dlg As FileDialog
Set Dlg = Application.FileDialog(msoFileDialogSaveAs)
Dlg.InitialFileName = DestFile
Do While True
If Dlg.Show = 0 Then
Exit Sub
End If
DestFile = Dlg.Item
If Not fso.FileExists(DestFile) Then
Exit Do
End If
Loop
End If
InFile.Move DestFile
End Sub
Here's some really quick code that I knocked up but basically looks at it from a different angle. You could put a combobox on a userform and get it to list the items as the user types. Not pretty, but it's a start for you to make more robust. I have hardcoded the directory c:\ here, but this could come from a text box
Private Sub ComboBox1_KeyUp(ByVal KeyCode As MSForms.ReturnInteger,
ByVal Shift As Integer)
Dim varListing() As Variant
Dim strFilename As String
Dim strFilePart As String
Dim intFiles As Integer
ComboBox1.MatchEntry = fmMatchEntryNone
strFilePart = ComboBox1.Value
strFilename = Dir("C:\" & strFilePart & "*.*", vbDirectory)
Do While strFilename <> ""
intFiles = intFiles + 1
ReDim Preserve varListing(1 To intFiles)
varListing(intFiles) = strFilename
strFilename = Dir()
Loop
On Error Resume Next
ComboBox1.List() = varListing
On Error GoTo 0
ComboBox1.DropDown
End Sub
Hope this helps. On error resume next is not the best thing to do but in this example stops it erroring if the variant has no files
Trying to use Excel VBA to capture all the file attributes from files on disk, including extended attributes. Was able to get it to loop through the files and capture the basic attributes (that come from the file system):
File Path
File Name
File Size
Date Created
Date Last Accessed
Date Last Modified
File Type
Would also like to capture the extended properties that come from the file itself:
Author
Keywords
Comments
Last Author
Category
Subject
And other properties which are visible when right clicking on the file.
The goal is to create a detailed list of all the files on a file server.
You say loop .. so if you want to do this for a dir instead of the current document;
Dim sFile As Variant
Dim oShell: Set oShell = CreateObject("Shell.Application")
Dim oDir: Set oDir = oShell.Namespace("c:\foo")
For Each sFile In oDir.Items
Debug.Print oDir.GetDetailsOf(sFile, XXX)
Next
Where XXX is an attribute column index, 9 for Author for example.
To list available indexes for your reference you can replace the for loop with;
for i = 0 To 40
debug.? i, oDir.GetDetailsOf(oDir.Items, i)
Next
Quickly for a single file/attribute:
Const PROP_COMPUTER As Long = 56
With CreateObject("Shell.Application").Namespace("C:\HOSTDIRECTORY")
MsgBox .GetDetailsOf(.Items.Item("FILE.NAME"), PROP_COMPUTER)
End With
You can get this with .BuiltInDocmementProperties.
For example:
Public Sub PrintDocumentProperties()
Dim oApp As New Excel.Application
Dim oWB As Workbook
Set oWB = ActiveWorkbook
Dim title As String
title = oWB.BuiltinDocumentProperties("Title")
Dim lastauthor As String
lastauthor = oWB.BuiltinDocumentProperties("Last Author")
Debug.Print title
Debug.Print lastauthor
End Sub
See this page for all the fields you can access with this: http://msdn.microsoft.com/en-us/library/bb220896.aspx
If you're trying to do this outside of the client (i.e. with Excel closed and running code from, say, a .NET program), you need to use DSOFile.dll.
'vb.net
'Extended file stributes
'visual basic .net sample
Dim sFile As Object
Dim oShell = CreateObject("Shell.Application")
Dim oDir = oShell.Namespace("c:\temp")
For i = 0 To 34
TextBox1.Text = TextBox1.Text & oDir.GetDetailsOf(oDir, i) & vbCrLf
For Each sFile In oDir.Items
TextBox1.Text = TextBox1.Text & oDir.GetDetailsOf(sFile, i) & vbCrLf
Next
TextBox1.Text = TextBox1.Text & vbCrLf
Next
I was finally able to get this to work for my needs.
The old voted up code does not run on windows 10 system (at least not mine). The referenced MS library link below provides current examples on how to make this work. My example uses them with late bindings.
https://learn.microsoft.com/en-us/windows/win32/shell/folder-getdetailsof.
The attribute codes were different on my computer and like someone mentioned above most return blank values even if they are not. I used a for loop to cycle through all of them and found out that Title and Subject can still be accessed which is more then enough for my purposes.
Private Sub MySubNamek()
Dim objShell As Object 'Shell
Dim objFolder As Object 'Folder
Set objShell = CreateObject("Shell.Application")
Set objFolder = objShell.NameSpace("E:\MyFolder")
If (Not objFolder Is Nothing) Then
Dim objFolderItem As Object 'FolderItem
Set objFolderItem = objFolder.ParseName("Myfilename.txt")
For i = 0 To 288
szItem = objFolder.GetDetailsOf(objFolderItem, i)
Debug.Print i & " - " & szItem
Next
Set objFolderItem = Nothing
End If
Set objFolder = Nothing
Set objShell = Nothing
End Sub
Lucky discovery
if objFolderItem is Nothing when you call
objFolder.GetDetailsOf(objFolderItem, i)
the string returned is the name of the property, rather than its (undefined) value
e.g. when i=3 it returns "Date modified"
Doing it for all 288 values of I makes it clear why most cause it to return blank for most filetypes
e.g i=175 is "Horizontal resolution"
