I want to create a program that auto copy text file from one folder to another folder . is it possible to make in windows form in vb.net ? if not what about in console apps ? i tried to search but i didn't find an answer for both. please help me i'm new to to this. I want to copy all the text file that is being save to c:folder1\test1.text copy to c:folder2\test1.text then test2.text,test3.text all the text file that are being put in folder1. i want to copy in folder2.
now i only have this code:
it will only copy 1 specific textfile with file name test.txt.
enter code here
My.Computer.FileSystem.CopyFile("C:\CopyTo\test.txt",
"C:\CopyHere\test.txt")
Of course! First of all we need a function that search for files.
Public Sub SearchFiles(ByVal Pattern As String, ByVal Path As String, ByVal FilesFound As ArrayList)
FilesFound.AddRange(Directory.GetFiles(Path, Pattern))
End Sub
But where we should save the list of files? We can use a Array for it. Also we should define our output and input folder
Dim files As New ArrayList
Dim inDir As String = "input path"
Dim outDir As String = "output path"
We can now call this function like this:
SearchFiles("*.txt", inDir, files)
All .txt files in the folder are now saved in our Array List. But how we can work with it? We can now work with it like this:
Try
For Each file As String In files
Dim fName As String = Path.GetFileName(file)
My.Computer.FileSystem.CopyFile(file , outDir & "\" & fName, overwrite:=False)
Next
Catch ex As Exception
Console.WriteLine(ex.ToString)
End Try
This will copy every .txt file that where found in our inDir to our outDir. If something goes wrong then you will see this in the console. Try it out and understand how it works :)

I am working in Visual Basic 2017. I have tried to add the file to the Debug folder, but then it just shows that the txt file ienter image description heres missing. I don't have the option under the "Word Solution".. How can I make the file show up? It keeps telling me it doesn't exist.
Dim inFile As IO.StreamReader
Const FileName As String = "words.txt"
Dim subscript As Integer
You can get the path of the directory (Debug or Release or any other) of the *.exe file with:
Dim directory as String = My.Application.Info.DirectoryPath
Using this information, you can then construct the full path with
Dim path As String = IO.Path.Combine(directory, FileName)
If IO.File.Exists(path) Then
...
You can check in Windows File Explorer to see where the file actually is (notice the Copy Path on the ribbon). In File Explorer you will see that the .exe you are running is down 2 directories from the Words Project directory. The double dots in the path is an old DOS way to navigating around directories without having to type out the whole path. This tells the compiler to find the file up 2 directories from the current directory.
For testing purposes this will work. For a release version you could add the file to Resources and access it the same way in any version.
You don't need a stream for a text file. .ReadAllLines returns an array of the lines in the text file
Private Sub OpCode()
Dim words = File.ReadAllLines("..\..\words.txt")
End Sub
I use Foxit Phantompdf, the complete version and ACCESS.
In our program, we have to save multiple pdf files, some of them should be merged in single files when saved.
Here is the code I use;
Dim phApp As PhantomPDF.Application
Dim n1 As String
Dim n2 As String
n1 = "c:\Temp\F3769-190136-GROUPE OCÉAN.pdf"
n2 = "c:\Temp\f3769-190136-GROUPE OCÉAN- facture.pdf"
Set phApp = CreateObject("PhantomPDF.Application")
Dim phCreator As PhantomPDF.Creator
Set phCreator = phApp.Creator
***'Call phCreator.CombineFiles("c:\Temp\F3769-190136-GROUPE OCÉAN.pdf|c:\Temp\f3769-190136-GROUPE OCÉAN- facture.pdf", "c:\Temp\F3769-190136-GROUPE OCÉAN.pdf", COMBINE_ADD_CONTENTS)***
Call phCreator.CombineFiles("""c:\Temp\" & n1 & "|'" & n2 & """" & ", " & """c:\Temp\F3769-190136-GROUPE OCÉAN.pdf"""" &", COMBINE_ADD_CONTENTS)
phApp.Exit
When I try it with the complete files names (in bold) the code works perfectly.
However, when I try to use variables, I get a
"Argument not optional"
error.
Can somebody help me ?
Thanks
Your string definitions in call line is incorrect.
You have defined n1 and n2 with the c:\temp already, and in your string conversion you add this again. I do not know if this is the route cause to your issue.
Furthermore I do not know the actual needed syntax for this phcreator.combine()
But is it not possible using only:
call pHcreator.combine(n1 & "|" & n2, …
The 'Argument not option' might imply you should add another input to your pHcreator, I would guess it could have something to do with FOXIT's combine function page settings. Try adding a input variable integer at the end of the function maybe?
But the fact that it works when writing strings in clear text would maybe suggest that the string manipulations is not correct?
I'm not a vba professional, but interested in the outcome, working myself with Foxit and also want to combine with vba. I'm currently not using version 9 som I seem to be out of luck, and only upgrading it I know what I want to do is possible.
I tried it, but got the same error message. So I took advantage of the fact that the function works when the file names are in plain text. I copied the files to be merged in a temporary folder and rename them. The renamed files are the then used in the merge function. It works perfectly, but Foxit adds a table of content page, and I don't know, yet, how to remove it. Here is my solution:
Private Sub Command4_Click()
Dim addi As String 'file to be merged to main file
Dim princi As String 'main file
Dim phApp As PhantomPDF.Application
'A temporary folder, in this case c:\t2, should be present
'In this example c:\Temp is the working folder
addi = "c:\Temp\filetomerge.pdf" 'full path of file to be merged
princi = "c:\Temp\mainfile.pdf" 'full path of main file
'fadd,pdf and fmain.pdf are the temporay files used in Foxit's function
FileCopy addi, "c:\t2\fadd.pdf" 'temporary file to be merged in temporary folder
FileCopy princi, "c:\t2\fmain.pdf" 'temporary main file in temporary folder
'Merge action
Set phApp = CreateObject("PhantomPDF.Application")
Dim phCreator As PhantomPDF.Creator
Set phCreator = phApp.Creator
Call phCreator.CombineFiles("c:\t2\fmain.pdf|c:\t2\fadd.pdf", "c:\t2\fmain.pdf", COMBINE_ADD_CONTENTS)
phApp.Exit
'Save merged file in working folder under main file name
Kill princi
FileCopy "c:\t2\fmain.pdf", princi
'delete temporary files
Kill "c:\t2\fadd.pdf"
Kill "c:\t2\fmain.pdf"
End Sub
So I am having trouble trying to reconcile this concept as every change I do doesn't seem to fix the issue.
I have multiline textbox and can enter multiple values separated by commas and here are the details:
Each value represents a folder
And each folder has multiple documents/other folders inside
All of these values are in one main directory (lets call it folder path)
For example say I enter in my textbox "65635,65636" each of those represent a folder in the directory i.e. "\folderpath\65635" and "\folderpath\65636", I am trying to zip these whole folders via DotNetZiplib, I know how to do this if I specifically reference one folder but is there anywhere to loop through the textbox to get the names of the folders and have the files added to one zipped folder?
Using zip As New ZipFile = new ZipFile
Dim files() As String = Directory.GetFiles(folderpath & textboxvalue)
For each textboxvalue in directory.getfiles
zip.Addfile(textboxvalue)
The zipfile function I have would know to loop through these as opposed to assuming it's one big file.
You must split textbox values in array first to get numbers separated by comma. Next you will need Combine your folder with this splited text values, creating path correctly.
Check if folder exists in system if Yes then get all files from Directory and for each filename zip it.
Something like this:
Using zip As New ZipFile("your zip filename")
For Each str As String In textboxvalue.Split(",")
Dim path as String = System.IO.Path.Combine(folderpath, str)
If System.IO.Directory.Exists(path) = False Then
Continue For
End If
Dim files() As String = Directory.GetFiles(path)
For Each fileName As String In files
zip.Addfile(fileName)
Next
Next
End Using
I am trying to find a way to read a specific file name in a directory and then put the file name into a variable. In my program I have a batch file that zips a folder called logs and then changes the name of zip to username_date_time.zip.
So basically if the filename was jobs_03152015_1315.zip I would want the entire file name but not the path stored into a variable. The file starts off on the user's local machine. It is then uploaded into a network share.
The network path will be uploaded to a database for others to view. I want to just add the unique file name to the end of a pre set path. Here is the code I am using.
Dim filePath As String = "c:\temp\logs\"
If (System.IO.Directory.Exists(filePath)) Then
For Each file As String In filePath
If file.Contains(".zip") Then
Dim zip As String = file
testbox.Text = zip
Exit For
End If
Next
End If
You can enumerate all files using the GetFiles() method of the static (shared in VB) Directory class, see msdn.
Assuming you have more then 1 file I add the files to a listbox control. But you could change that if you wish. I get the filename using the Path class. You will find a lot other helpful functions in this class.
Dim searchPath = "C:\temp\logs"
Dim files = Directory.GetFiles(path, "*.zip")
For Each file In files
listbox1.Items.Add(path.GetFileName(file))
Next
This should do it.
Your loop doesn't read anything. The string variable filePath is just the name of the directory, not a list of the files in that directory. Calling For Each over a string simply enumerates each character contained in the string
To get a list of files contained in that folder you need Directory.EnumerateFiles() and pass the filePath variable and the extension required.
It seems that you are interested only to find if that folder contains at least one file with zip extension. If this is the case then you could remove the explicit loop and write simply
Dim file = Directory.EnumerateFiles(filePath, "*.zip").FirstOrDefault()
If file IsNot Nothing Then
testbox.Text = Path.GetFileName(file)
End If
Using Path.GetFileName will return just the file without the path part
Try this code :
Dim FilePath As String = "c:\temp\logs\"
If (System.IO.Directory.Exists(FilePath)) Then
For Each File As String In System.IO.Directory.EnumerateFiles(FilePath)
If File.Contains(".zip") Then
Dim info As New System.IO.FileInfo(File)
zip = info.Name
testbox.Text = zip
Exit For
End If
Next
End If
Ok, here is my story:
I am building a fileviewer, and i am trying to delete the selected file in the listview.
when i try to delete it, it gave me an error saying the file wasnt found. I looked at my desktop and the file was there. here is the original code:
dim f as string = lv1.focuseditem.text
my.computer.filesystem.deletfile(f)
lv1.update()
this gave me that error. My updated code is supposed to show me where the computer thinks my file is:
Dim file As String = lv1.FocusedItem.Text
Dim testFile As System.IO.FileInfo
testFile = My.Computer.FileSystem.GetFileInfo(file)
Dim folderPath As String = testFile.DirectoryName
MsgBox(folderPath)
this shows a messagebox that shows the path of:
C:\Users\tgs266\Desktop\SIOS\SIOS\SIOS\obj\Debug\test.txt
but the real file location is:
C:\Users\tgs266\Desktop\test.txt
please help
How are you getting the filenames for the ListView? Is it just the filename and no path?
If, for example, lv1.FocusedItem.Text is "test.txt", and that is the value you use (without the path), by default the program will look in the directory it's executing in. This is most likely why you're seeing C:\Users\tgs266\Desktop\SIOS\SIOS\SIOS\obj\Debug\test.txt as the location, instead of what you expected.
If all the files are on your desktop, you can use Environment.GetFolderPath in conjunction with the Environment.SpecialFolder Enumeration to get the file, like this:
Dim file As String = lv1.FocusedItem.Text
Dim testFile As System.IO.FileInfo
testFile = My.Computer.FileSystem.GetFileInfo(Environment.GetFolderPath(Environment.SpecialFolder.Desktop) + "\" + file)
Dim folderPath As String = testFile.DirectoryName
MsgBox(folderPath)
However, if you're going to have files scattered throughout your system, you'd be better off storing the full path as #Plutonix indicates in his comment.
It looks like your code is looking in your applications path on the server while you want to look at the users desktop location.
