fileshare

I'm using a hex-editor control for C#, the source code and binary files can be found here. One problem when using it was that if a file was loaded in the hex-editor and another program, the other program can't save the file, because it's already being used by another process. So I asked the author of the control who told me to set the FileShare argument in the File.Open method in the FileByteProvider and DynamicFileByteProvider class to ReadWrite (it was originally only Read) would fix it. So I did that, but it still didn't work (same error). Setting it to Write only also didn't work, but

When using a file stream, and setting FileShare to None , and say two users accessing the same function at the same time want to read/write to that file. Will FileShare.None make the second users request waiting or will the second user's request throw an exception? //two users get to this this code at the same time using (FileStream filestream = new FileStream(chosenFile, FileMode.OpenOrCreate, FileAccess.ReadWrite, FileShare.None)) using (StreamReader sr = new StreamReader(filestream)) using (StreamWriter sw = new StreamWriter(filestream)) { //reading and writing to file } Msdn says: None

I am building a .net C# console program to deploy file to a windows file share server (folder that is being shared). The path is :: \\192.168.0.76\htdocs\public On running I am getting the error: [09:35:29]: [Step 1/3] Unhandled Exception: System.UnauthorizedAccessException: Access to the path '\\192.168.0.76\htdocs\public' is denied. [09:35:29]: [Step 1/3] at DeployFileShare.Program.CopyDir(String source, String dest, String[] exclude, Boolean overwrite) [09:35:29]: [Step 1/3] at DeployFileShare.Program.Deploy(String num, String source) [09:35:29]: [Step 1/3] at DeployFileShare.Program.Main

I need to be able to programmatically authenticate when trying to read and write files on a remote computer in a non-domain environment. When you type a command into the Windows RUN prompt that is similar to \\targetComputer\C$\targetFolder or \\targetComputer\admin$, where the targetComputer is NOT on a domain, you will be prompted to enter a username and password. Once you enter the username and password, you have full access to the remote folder. How can I accomplish this authentication programmatically in C#? I've tried.. --Impersonation, but it appears to only work in a domain environment

BACKGROUND I need to write a tool using .NET version 2.0 at highest (using something off the shelf is not an option for this client for political, commercial, and confidentiality/trust reasons) to migrate files from one server to another over the network. The servers are file servers for local teams, and certain team folders need to be migrated to other servers to facilitate a reorganisation. The basic idea is we read each file and stream it over the network out of hours and after a few days the data will be migrated. File permissions need to be preserved. As this will take a few days (we are

My question is based off of inheriting a great deal of legacy code that I can't do very much about. Basically, I have a device that will produce a block of data. A library which will call the device to create that block of data, for some reason I don't entirely understand and cannot change even if I wanted to, writes that block of data to disk. This write is not instantaneous, but can take up to 90 seconds. In that time, the user wants to get a partial view of the data that's being produced, so I want to have a consumer thread which reads the data that the other library is writing to disk.
