I've got an app which uses a background worker to copy files. It works fine but some files are quite large and it "appears" as though the app isn't doing anything. Is there an alternative to the File.Copy method of copying files so I can report on the progress of individual file copies, like the percentage complete?

im looking for code to copy the files from the floppy drive to a removable drive on the computer.For example:

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'm using "My.Computer.FileSystem.CopyDirectory(...)" to copy large directories (30-50gb) from one mapped share folder to another. Using "FileInfo.length" to add up all file and subfolder sizes, determines the 'origin directory' size just fine. However, if I use the same method for determining the size of the 'destination directory', mid copy, it returns the full file size, despite the copy not yet being complete.I'm at a loss as to why, as this method works fine in testing, going from a local PC t

During the file copy, Label2 isn't being updated. In fact, my whole form goes non-responsive. How can I fix this?
I cannot do the following:
File.Copy(Application.StartupPath & "wait.exe", "%APPDATA%WAIT.EXE")
Can someone remind me how I got about copying a file to that location?
So, I have a task where I need to basically copy about 600,000 PDFs, some of which can be 5-6 MBs from one network fileshare to another network fileshare on another pc.Now, I crawled through the directories, sub-directories etc etc and created what I call a Filename/Filepath Database lookup table. This table contains the name and the unc fileshare path of each file which comes in handy.I have used Multi-threading and File.Copy to "copy" the files and I getting about 45K files per 4 hours which I need to be significantly faster then that and I am seeing performance degrade over time

I am currently using the registry to get file descriptions for files. As an example, so that a DOCX file will return the description "Microsoft Word". I am doing this from the HKEY_CLASSES_ROOT registry key.However, registry access is extremely slow, and I need to do several thousands of these. Is there an alternative way to do this?

So in this text file, there is a bunch of info, but I am only needing a certain part. Here is an example of a text file (actually a .dat file, but is easily read):

I have a program that I copy a file from one server to another. This has been working well if the servers are on the same domain.I now need to copy a file to a server on a different domain. If I were to do this manually it would prompt me for my username and password.
I don't see any way to put a username and password with doing an IO.File.Copy. Is there a better way to do this?IO.File.Copy(strSource, strDest)

I am writing a backup program that zips files. Using some sample code I have the following that creates a zip file. Problem is it does not get any subdirectories or files. Where am i going wrong?
Dim azFileNames() As String = Directory.GetFiles(SourceFolder)
Dim objCrc32 As New Crc32()
Dim zipStream As ZipOutputStream
[CODE]...
Alternativley, there is another component to the zipping dll that I could probably bypass the above altogether. It is: FZ.CreateZip(DestFile, SourceFolder, True, "", "") Where DestFile is (Output stream as system.io.stream). I'm trying to read all the files, directories, sub dir and files, etc from a specific location, let's say 'My Documents' into Destfile in which the FZ.CreateZip zips the file. FZ is FastZip which is from icsharpcode.net. They have c# examples, but that's greek to me. I'm trying to just learn VB!
Looking for an idea of where the best place to keep files for a program. I use them frequently and they interact with the program directly. I want to place them in a place where they won't be easy to find if someone is just cruising thru the directories. Any ideas?

View 1 RepliesI 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.
I seem to remember reading the MSDN somewhere that there was another method to download files from URIs other than using the webclient object. I'm trying to download some raw php files but every time I use the webclient object the server interprets them as an HTTP request and instead serves the default web page that the php file builds and not the php code itself.
View 3 RepliesI wrote a program to download and play AVI files the files are large in size and long time wise. I have the files playing as they are being downloaded but i can't see how long the file is or seek reliably. i was reading that the AVI headers are in the last 512kb of the AVI file *why would't they put it at the start* lol so my question is is there a way to download the last 512Kb of the file i'm downloading. i have the Bytes Read and Length of the file while its downlaoding i'm just not sure where to go from there, or how to do it atleast. If i had the length in time of the Avi file i could set the trackbar to be able to seek properly. or if someone has an idea how i could get the time of the video by using fps and some math i could prob do it that way too but idk how i would tell how i can find how many kb are in the fps i'm sure it changes so think that way is't going to be reliable. how to get the last 512kb would be the best option not sure if it can be done even.

View 3 RepliesIs there a way to get a list of files in a certain directory and then put them in a context menu strip then when they are clicked have the program open the file.

I should mention that I'm mainly concerned with Random files.Which is the best method?
1.) Open file, manipulate data and immediatly close the file. (Which means doing this alot everytime data needs to be read, edited, deleted, or saved)
(2.) Open the file when the app starts and let it open for data manipulation until it's time to close the app at which time the file would be closed.
I was always taught option 1. The main reason at the time was to cut down on the chance for data corruption in the file or an outright loss of the file due to outside circumstances like power failure.
I'm programming a small windows app that allows the user to fill out some fields and then creates and runs a batch file based on their entries. The program works, but it doesn't.The program creates the batch file just fine but when it tries to run the batch file, it gets errors in the cmd window saying it cannot find the scripts the batch file is trying to call. What's confusing me is that if I take the batch file the program created and run it myself, it works just fine so I know it is not the batch that is the problem. My best guess is that there is some security setting for vs.net that I've overlooked but I am only an "every once in a while" programmer so I really don't know where to look. Additionally after running the batch, the program is supposed to delete the batch file but that fails as well with the message that it cannot find the batch file, the same batch file that it had just created and run.
