I am writing a program that acceses a file in VB/Visual Studio 2008 on Win7 and running it as a user who has admin credentials. I am opening the file with the following code:
Dim Input As New FileStream("C:FileTest est.txt", FileMode.Append, FileAccess.Write, FileShare.None) To test to make sure I can't access this file, I tried to open it with Notepad and I was able to and got no errors. I wrote a new value using Notepad and even saved it and I didn't get any errors form Notepad or my VB program.
I then went on and treid to open the same file twice from my VB program as:
Dim Input As New FileStream("C:FileTest est.txt", FileMode.Append, FileAccess.Write, FileShare.None)
Dim Input2 As New FileStream("C:FileTest est.txt", FileMode., FileAccess.Read, FileShare.None)
And I receivded an error in my VB program as expected. So the FileShare.None switch kind of works. Although I was still able to open the file with Notepad while my VB program had it open. I was aslo able to open Windows Explorer and reame it and even delte it while my VB program had it "open", in the write mode no less without my VB program knowing anything about it.
Why are other applications able to ignore the FileShare.None switch? Seems pretty useless if that's the case. And a huge secruity problem

I create a string array from a bunch of files that were dropped on a control after that i use a loops to pass that data into an array of my pictureObjects object (just stores filePath info and some other things).for some reason after it's been passed to the control the "My.Computer.FileSystem.RenameFile" doesn't seem to work at all... it's a valid file name and everthing.
Dim sFileArray() As String = e.Data.GetData(DataFormats.FileDrop)
'load sFileArray into new array of picureObjects
ReDim dropedPicture(sFileArray.Length)
Dim dropedOnPictureBox As Integer[code]......

This is what I've wrote.. and it fails to rename existing files
For Each file As String In listbox1.Items
IO.File.Copy(file, IO.Path.Combine(fbCopyto.SelectedPath, IO.Path.GetFileName(file)))
While IO.File.Exists(fbCopyto.SelectedPath & file)
file= file & x & ".wav"
x += 1
End While
Next

in the current project im making i've decided to add in some tools, 1 of which is a renamer based of a renamer app that already exists (called scdtoolz), i want to build my own version of it so i can learn some new things, and build a nice GUI version of it.[code]So what i have managed to determine is that the current app scans the folders contents for the CRC32 Checksum, and renames based of that, since the 456.bin's CRC32 Checksum was 2274F80B, and in the text file 2274F80B is found here 'WWF - Rage in the Cage (T-81015)(U)#2274F80B#'So now i have determined game identification is based of the CRC32 checksums, how would i go about coding a similar ap in vb.net?first i need to make the app scan a folder, but how to return crcchecksum? and then rename if check = XXXX? If MD4 sums are easier/simpler i can use those instead, im lookin at a few hash app sources now, so i think i can see how to get the md5 but not the crc32 yet, or how to rename the 2 files and folder based of the text file.

I have a script task inside a for each file loop which moves files from one directory to another. It uses the file.move command which works fine unless the file I am moving already exists in the destination directory. I would like to add the datetime string to the filename before moving it or alternatively an incremental variable to make the filename unique before its moved.

I am trying to change the file names of all the files in a directory based on content of the file. So I am opening the file, reading the content, storing the new file name in a variable and then trying to change the name of the file. This is not working because when I start this loop I am opening the file and viewing it so it won't allow me to change while the file is in use. Should I store the old and new file names in an array and do the renames after the For Next Loop is complete?

A while back I asked about going beyond basic FTP upload/download on this thread, and the response I got about using FtpWebRequest was very helpful. Now I'm looking at something that doesn't seem to be offered in FtpWebRequest: renaming a file on the server.
My situation: several times each month I update MyConfig.csv on my website. This file is generated on my computer by Excel to control who can access which files on the site, and it runs a bit over 1 MB. The scripts on the server parse through the file to keep things running smoothly. Given that the file can take some time to transfer, I typically will upload NewMyConfig.csv to the server with a commercial FTP program, then when it is in place I rename the existing file to MyConfigBackup20100521.csv and then rename NewMyConfig.csv to MyConfig.csv. This way, if there is a problem with the upload, everything keeps running smoothly because the existing MyConfig is undisturbed, and the window when a customer might get an error from the scripts because there is no MyConfig.csv is reduced to a couple of seconds between the two rename operations.
Now I'd like to automate all of this to happen with a VB program, but it looks like FtpWebRequest only allows you to rename directories, not individual files, on the server.

I have a program that I have been creating for work, however, I am down to the last part and can't figure it out......The code below copies files from one directory to another from a list of file names in the first column of an excel sheet. This part works fine. What I am trying to figure out is how can I have a prefix in column B where it renames the file while being copied to the destination folder?
Example:
Column A
book1.tif
book2.tif
book3.tif

Basically I download lots of TV shows and they're never named in the way I like; they're named like this "The Office.S06E22.HDTV.XviD-NoTV."So I was wondering if I had a .txt file with all the episode names I could make a program to rename all the video files in the right order so they're named like this "The Office Season 6 Episode 22 - Secretary's Day."So I want to copy and paste a list of correct episodes names into a text file. Then I want to read the text file, which I already know how to do. Then, and this is the bit I'm struggling with, I want to read the text file, one line at a time, and it renames the top video file with the top episode name and so on.

way to retrieve list/rename hiddne files from the remote host. I need to upload the file to a server and then move it to another directory, but the file after being transfered becomes hidden. If I try to rename it any way I get the dreaded 550 in response. I would hate to move to commad line scripting which at the moment seams to be my only option.
