Copying And Moving Files?
Nov 15, 2011
I have been creating a program that copies and moves files from folder to folder; I am using this sort of code;
fileToCopy.CopyTo("path here...")
or
FileToMove.MoveTo("path here...")
My problem is, when I am copying or moving a large file, It's taking so much time and my program is hanging until all the files are completely moved or copied. How about, using a progressbar instead, so that the user will be able to see the progress of copying and moving instead of the program freezing?

I'm just testing things and seeing if I can get things working and if I can then I want to try and develop this into something more. So far its just a simple button1 finds all files with extension of .mp3 in C: and displays all the findings in a listbox. I then want to use button2 to copy or move (I want to see how to do both) all of the files that are in that lisbox to a directory of my choosing. Here is what I have so far.
Imports System.IO

I am busy writing a application that i can set up a list of files to copy from one location to a remote network drive.
THe program has a list of "jobs" in a datagrid that it loops through and executes in sequence. What i have now is a background worker that reports the status of which job it is on (File 1 of 5) but i would like something that shows the status of the current copying file as sometimes large files can look like it's stopped on the network
I am using the System.io.file.copy structure, but have also tried the my.computer.filesystem.copyfile (which shows the status in a "windows" copy box)
So, what i would like is some guidance on how to create a function that will copy the file but also report back progress periodicly. I don't want to read and write byte for byte as im worried this will be too slow.
Also, is there a better way/function to use to copy files? Looking for best speed

i have been searching Google for weeks now looking for help on a project, i'm not in school college etc, i am a network admin in a secondary school. Basically i was sick of teachers/pupils losing their pen drives and complaining to us that their work is missing, i set out to create a program to ease the backing up process to ensure this happened less often. i did manage to create a program using 'Get current directory' & 'Copy directory' and it works fine but not to the standard i want. Here is a clip of my current program, pretty neat for a beginner i think.I want the .EXE to sit on the pendrive and extract everything to a backup folder when it's run.Because (h:/) or whatever the letter, is a DRIVE, copy directory method wont work.

I want to include a function in my program that involves my copying files from my cd drive D:/ to my hard drive C:/. The code I'm using is below but it isn't working. The first one came up with an error, and the second one didn't come up with an error but didn't copy the files.
vb.net
My.Computer.FileSystem.CopyFile(foundFile, destPath & foundFile, True)
Dim srcPath As String
Dim destPath As String
srcPath = ComboBox1.Text & "Web Browser"
destPath = Environment.GetFolderPath(Environment.SpecialFolder.CommonProgramFiles)
[Code] .....
The combo box allows the user to select which drive the cd is in, incase you were wondering.

I am looking for a way to copy files from one folder to another, I've tried a few examples online but none seem to work. I need one that copies and replaces and one that only copies files which aren't already in the destination folder?

How do you recommend I copy large files over the LAN (>20GB)Currently I am using File.Copy.Another question I have is how can I implement this class to be self contained, meaning that it would report progress to the object that called it? or do I have to define a delegate in the calling object?
Code:
Public Class cCopier
Private Delegate Function CopyProgressRoutine(ByVal totalFileSize As Int64, ByVal totalBytesTransferred As Int64, ByVal streamSize As Int64, ByVal streamBytesTransferred As Int64, ByVal dwStreamNumber As Int32, ByVal dwCallbackReason As Int32, ByVal hSourceFile As Int32, ByVal hDestinationFile As Int32, ByVal lpData As Int32) As Int32

I know you can copy a file using:[code]The only way I know how to copy multiple files is by using a for loop, but if you choose to display a dialog box, you get a dialog box for every file you copy instead of one showing the progress of all the files.So with that said, is there any way to copy multiple files, and only have one dialog box displayed?

So this is what I have right now, I can get it to copy But I am wanting to rename the files with the date inside of the new Directory name, It is going to be used for making a copy of outlook.pst files. But as you can see I can't put in concrete names of where to save it because I want the user to be able to choose where to save it as it will be saved on a server with folders for each individual user.
Public Class Form1
Dim Folder1
Dim Folder2
Dim FolderBrowserDialog1 As New FolderBrowserDialog
Dim FolderBrowserDialog2 As New FolderBrowserDialog
Dim currentDate As Date = Date.Now

I have three data files that I include with my project. They are all set to Build Action Content and Copy to Output Copy Always. I have a preferences form that allows the user to copy these files to a folder of their choosing. It works fine in the IDE. However, when deployed one file will copy but the next returns an error the the file cannot be found. In the following code block a deployed application will copy ABW11Data.sdf but cannot find 100610_40.dtb or 2118@005.dtb. They are in the deployment files and I can search and find them in the clickonce installation although they are not in the same place as the ABW11data.sdf.
If My.Application.IsNetworkDeployed = False Then
My.Computer.FileSystem.CopyFile(My.Application.Info.DirectoryPath + "ABW11Data.sdf", TextBoxFolder.Text, True)
My.Computer.FileSystem.CopyFile(My.Application.Info.DirectoryPath + "100610_40.dtb", .SelectedPath + "100610_40.dtb", True)

I would like to transfer files from an FTP site to my folder on C drive. For instance, I have an FTP site 169.69.20.100. If I go thru my IE I can see the lsit of files in here. I can simply click on it and IE will ask me if I want to open it or Save it. I want to automatically download them into my folder on my HDD. can this be done thru VB.Net?

I have run into a problem with a couple of the "Sync" applications I wanted to create. In both instances, I am trying to connect a Portable Device to my computer and access it using VB.NET. One application would pull the pictures in from my camera, rename them, and put them in folders according to their date taken. The other would place the podcasts I have downloaded onto my Mp3 Player. I have the logic for both so that if I run it on two Windows directories, for example (C:Source and C:Destination) but when I try to access the Portable device using a directory browser, the "OK" button is disabled. Is there any way to access the directories on such a device?

I'd like to start off by saying I'm extremely new to programing (3weeks) and I've come across a problem with my code. I've created a form that copies files from one folder to another. A user can either copy all files or selects files from a list box. Due to the size of the files the program freezes when performing the task. I have used backgroundworker component for copying all files and it works fine (no freeezing ). When I use the backgroundworker component for copying selected files I receive an error.
Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click
BackgroundWorker2.RunWorkerAsync()
End Sub

I don't have muc experience with backgroundworkers, but this is basicalmly what I want it to do:
- Copy files from a list
- Add Succes/Fail to a listview
- Report Progress
Private Sub BackgroundWorker2_DoWork(ByVal sender As System.Object, ByVal e As System.ComponentModel.DoWorkEventArgs) Handles BackgroundWorker2.DoWork
'2 groups
Dim Succes As New ListViewGroup("Succes")
[code]....
It doesn't copy the files, nor does it report progress.

Is there a way to copy files where it gives you the option to overwrite all and show graphically the files being copied, in much the same way when copying files within windows.What I have at the moment is this:
My.Computer.FileSystem.CopyFile(DataDirectory.DataSource, BackupPath & "Restel.bak", True)
For Each FileFound As String In My.Computer.FileSystem.GetFiles(SystemDataPath & "", FileIO.SearchOption.SearchTopLevelOnly, "*.rtf")
FileName = My.Computer.FileSystem.GetName(FileFound)
My.Computer.FileSystem.CopyFile(FileFound, BackupPath & "" & FileName, FileIO.UIOption.AllDialogs, FileIO.UICancelOption.ThrowException)
Next
which overwrites automatically or shows it graphically prompting each time if the file already exists.

I am very new to programming and I am having trouble getting my code to work properly.I am trying to write what I thought was a simple program, but I everything I have tried has not worked properly.I am creating a utility that will take installation and database files from one computer and copy those files to a flash drive so the flash drive will have the new version. The flash drives in question would either have one of two previous versions of the software on it or it will be blank. I decided to do this in two steps. First I check the computer for the new database and the flash drive for the old ones. I do this with the following code. [code] Next, I am deleting files from the flash drive if the old database is there and copying the files from the computer to the flash drive and showing progress on the progressbar. Here is where I am going all wrong. I have tried it a number of different ways, and unfortunatly (I'm kicking myself right now), I have not saved the code from the other methods I have tried.I have not been able to figure out how to get the background worker to work with what I am trying to do, though I have seen a lot of code over the past few weeks with examples of how to use it. It is a little above my head in terms of figuring it out by myself. So what I have used is the following code: [code]

I have a file that is constantly altered, and if an error happends, I want to have a backup. I was wondering if there's a way to make a script that will copy all the files in the selected folder, and post/overwrite them every 20 minutes in a back-up folder or something, and I say overwrite so it doesnt take up 298347234 gigs of data.

I'm trying to copy multiple files from a directory, put them into an array, then copy just the 30 newest files(I haven't coded the 30 newest loop yet). I added a list box to the following code just to ensure the all the files are storing into the array properly... they are. When it try's to copy, it renames the first file to .log, then tells me that the .log file already exist. How do I get it to copy and keep the source file name in the destination folder Eventually I'll loop this and grab only 30 of the files.
Here's the code I'm playing with:
Private Sub transferButton_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles transferButton.Click

I need to import data from files generated by a 3rd party program which scans our inventory as it passes through the production line.This program, rather than inserting the data into a backend db or even a log file, creates a series of .asc files per item that passes.
I originally intended to watch that folder and move new additions to a temp location, import to our db, then move to a final resting place for archiving. As it turns out, i cannot move these files, because the program checks this directory to perform a few critical functions
1. the file name serves as a primary key to ensure item ID's are not duplicated...
2. when running a sequential set, it auto-increments from the last file created.
Since I cannot move the files, is it possible through System.File.IO or some other means to copy files to a temp location, run my imports, then move to the final location then continue to watch this directory, and only move files to the temp location that do not yet exist in the final directory?

I have an issue with the Windows permission system. And every time it tries to do something that needs a windows permission (to be ran as administrator) it fails !
At the moment I was trying to implement an updater which should download a file from an ftp site but because copying a file into one of the program files folder requires a permission I am not able to do this.
