Copy File Leaves Blank File With Same Name?
Oct 6, 2009
I have used the following method to copy a file from one location to another:
My.Computer.FileSystem.CopyFile(WorkPath$ & "vmcg.vmc", sessionsPath$ & "vmcg.vmc", True)
with workpath being the original location and sessionspath being a string with the new location. True is the overwrite property.The file copies a blank file with the same name, but what i want (obviously) is to copy the file and the contents.ie how am i suppose to copy a file?If you're not living on the edge, you're taking up too much room?

I have a program that uses IO.File.Copy to copy files from point a to point b. Its slow, which is fine because there rather large files. I was wondering if there is way to get an estimate time to copy a particular file(s).
Example: File a will take 1 hour to copy, File B will take 30 minutes to copy. Estimate Total Time: 1 hour 30 minutes.

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?

Before I begin I would like to mention that I am not a noob in VB, it's just I've never had to do anything this complex before. Basically what I want is to have a program that you can load a txt file in, have it copy key words, and paste it in a textbox so I can use it later on. 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 am wondering if Global.asa can handle a procedure like this:

'Response.Write(Err.Description) 'or your own custom error message
Dim msg As String

The idea is to have a central place to put the routine in instead to copy it into every .vb file that belongs to each .apsx code file.

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 developing an Application in VB.Net 2.0. I have a module which would copy files from the Local Machine to a shared folder on remote machine. This shared folder on the remote machine is an authenticated folder. So, after searching on the Internet I found the following piece of code.[code]Another point to note is that when I connect to the File Share using Windows Explorer and then try to execute the application, it works properly.I am not sure why I am getting the error when I do not connect to the Shared Folder using Windows Explorer.Do I have to set some property so that the Credentials passed in the authentication are used.I also checked some posts that suggested setting up Mapped Drive to the Shared Folder on the Local machine and then to copy the file using IO.File.Copy function. However, I cannot use this as this Remote Folder should be only accessed through the application and not in any other case by the User. The users will not even have the credentials to this remote Server as it will be configured by the admin.So, Is there any way in which I can set this up and transfer the files from local machine to a remote shared folder?

Ideally I'd like to be able to copy/move between an accessible folder on my local drive and a network share that I don't have permission to access (but the application would). I am using impersonation to give me access to the files in the network share but using System.IO File.Move or File.Copy forces me to use the same credentials for each location. Is there a way around this?

In my program I allow the user to copy a file from one folder to another. If the file already exists in the target folder I want it to be overwritten.
All that works just fine - I'm not asking how to copy files.
But here's an example
Source file is:-
\SomeMachinesomeFolderfile.xyz
Target is:-
P:file.xyz
This might at first look like two separate files but in this case P: is mapped to \SomeMachinesomeFolder so the source and the target are actually the same file and the file copy will obviously fail.
Of course I want it to fail but my problem is that the windows generic error message seen by the user is not very helpful. It says something simple like "... can't be copied because it's busy". If the user isn't very bright he doesn't realize he's selected the same file both as source and target and he doesn't understand why it's busy.
What I want to do is detect in advance that the source and the target are the same file and display a more meaningful message to the user and not even bother trying to copy.
So, is there a way to detect that
\SomeMachinesomeFolderfile.xyz
and
P:file.xyz
are actually the same file?

Recursive File Copy based on file extension. I have a single root folder that contains numerous folders that contain a few files that I want to extract. For this example, lets state that I want to copy all �txt� extensions and put them into a repository folder.

\root\Folder1\abc.txt

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 working on a program using VB.Net 2010 which will enable me to setup groups of files & folders for back up with syncing capabilities etc. I have a concept program which is based on some sample code I found out in one of the VB.Net forums. I have modified it from a command line based program to a form based program. At the moment I consider this code to be a "concept" program which once I have the various copy/sync routines developed and debugged will be integrated in to another program I wrote for
creating "Back Up" groups to automate the process. There are some 3rd party programs that do similar things that I want to do such as Microsofts Sync Toy, but none of them offer the grouping and exclusions options that I am going to program in to this backup/sync program.
So here is my problem, I have the included code taking two folders, a source and a destination, and copying everything from the source to the destination. It will skip over any unchanged files/folders and will delete anything found in the destination folder that is not found in the source folder and it will update all files in the destination folder that have a newer version in the source folder. In other words it will mirror image the source to the destination but will be smart enough not to copy unchanged items from the source to the destination thereby saving a lot of time. The sync part of the program is working fine, the displaying of the progress and results is not.

(VS 2008, VB, 3.5 framework) Files have my name in the Owner property of the file, I want the owner value to be blank. I want to create a VB app that will loop through each file and clear out the owner property value. About 40 folders with about 20,000 files. What is the best way to loop through folders, and update files? Can the owner property value be set to blank?

I have a text file that has multiple blank lines and Im trying to return all the lines between two of them specifically
so if I have a file that looks like this:
[Code].....
I would like to grab lines 8-13. Unfortunately, it might not always be 8-13 as it could be 9-20 or 7-8, but it will however always be between the 2nd and 3rd line break.
I know how to trim characters and pull out singular lines, but I have no idea how to trim entire sections.
