Copying Files From Pc To USB Drive Showing Progress
Jun 7, 2011
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 read about the UNC path, but that doesn't seem to be making much difference, it may be that I need a user name and password for the connection, can anyone demonstrate code that allows username and password entry so that a file can copy to and from a mapped network drive or the UNC is "\serverarchiveJune"

I have to create a program to manage a large number of USB Thumbdrives. In short, the drives will contain corporate images used by technicians to prep machines in the field. I do not have to create the images as they are already provided. Since I have to create 50 plus of these at one time, I am looking at writing a program to automate the process. As it stands now, formatting, partitioning, and copying the image to each key individually is, as you can understand, not efficient time wise. I have already purchased two industrial quality 7 port powered hubs.
The plan is to be able to: Fill all 14 slots in the hubs with USB ThumbdrivesUse the program to select the drives to prepareHave the program format and partition the drives (bootable)Copy the contents of the image folder provided to the USB keys. The idea is to do the above by filling all the slots and hitting one button, then walking away to do other work. When done, the drives would be ejected, and the next set of 14 installed.
I have already created the User Interface. It consists of: 5 buttons (Scan For Drives, Format Drives, Build Drives, Build And Format Drives, Exit).One "Select Source" entry field to select the source of the Image Files.One Checked Entry List. This is where all available drives will be listed, and the one's desired to be checked.
Now, it has been 20 years since I did any coding, and all of that was done in languages that are pretty much dead today (Turbo Pascal, Clarion Professional Developer and R:Base), so to say I'm behind the curve is an understatement. While I was never a real fan of Basic, I have some experience with it. But today's VB.Net ain't your daddy's basic, and there's no way I have time to learn C or C++. I have the Express version of Visual Studio 2010, which should be fine for this project.

The drive is connected via USB and the problem I'm having is that, periodically, while my code is executing, the usb drive seems to disconnect and reconnect. (Nothing to do with the program, but the drive itself).I want to find a way to prevent these temporary drive reconnects from interrupting my code. IE, i want to insure that whatever read or write that is requested is actually executed even in the case of a temporary drive interruption.

I have a form that I will be using to copy directories of photos from memory cards to locations on a computer. I would like to add a progress bar to the application to show the progress of the copying in real time. This is the code that I use to copy the directory in the first place
Dim SourceDir As String = SourceTextBox.Text
Dim DestinationDir As String = DestinationTextbox.Text
If System.IO.Directory.Exists(DestinationDir) Then
My.Computer.FileSystem.CopyDirectory(SourceDir, DestinationDir,)
Else
My.Computer.FileSystem.CreateDirectory(Destination Dir)
My.Computer.FileSystem.CopyDirectory(SourceDir, DestinationDir)

I have a filesystemwatcher which place files in a queue when they are created. From the queue the files are further processed (xml into SQL database).
The mechanism works fine, but I want to add a progress bar to follow the progress of the files in the queue: processing 1 of 10......2 of 10......3 of 10 etc.For testing, I created a batch file to simulate the creation of files, so the filesystemwatcher can to his work and place the files in the queue. When I tell the batchfile to simulate the creation of 20 files, I see that the amount of files in the queue change. For example;

I am trying to run a routine to load a gridview from a sql table. I would like a progress meter to run until the grid is loaded. I have tried using the background worker component...but I havent found a really basic example of how to run the progress meter on the uiwhile loading the grid in the dowork event.. is this as intricate as it looks? I just have the meter tied to the tick event of a timer

I'm trying to make the progress bar to display the amount of free space C: has. I have successfully do so with my code which is:
Vb.net
Try
Dim b As String
Dim c As String
Dim dvr As New DriveInfo("c:")
b = CStr(dvr.TotalSize 1000000)
c = CStr(dvr.AvailableFreeSpace 1000000)
[Code] .....
As a last touch to this code I thought I would add a percent bar so it would look more professional. I did so with:
Dim Per As String = (c b * 100)
The problem is that it displays always zero percent why?

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.

i have this right now:
ListBox1.Items.Clear()
Dim di As New IO.DirectoryInfo(TextBox1.Text)
Dim aryFi As IO.FileInfo() = di.GetFiles("*.*")[code]......
and that displays only the file name, like text.txt but i want it to display C:/Text.txt and all the files in the subfolders too, like C:/Program Files/Test2.txt but i just get test.txt from only the c:/ .

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 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 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.

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?

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.
