How To Tell System Copy Source To Destination If Possible
Mar 30, 2011I'm trying to copy a file, using System.Copy. The destination, if it exists, should be overwritten. I had been using a single line of code for about a month, without problems : IO.File.Copy(SourceFile, DestFile, True)But problems started about a week ago, when I started more advanced checks. Partially locked files fail to copy, and the destination gets deleted. Locked files, on the other hand, work correctly: they just trigger a file in use exception.So I added this line before launching the copy:Using TestForAccess As New IO.FileStream(SourceFile, IO.FileMode.Open, IO. FileAccess. Read, IO.FileShare.None) : End Using..This was supposed to launch an error if the file was in use. But it is to sensitive. Some files (such as thunderbird's abook.mab) trigger an error in this added code, whereas they copied fine before (and you can copy them in explorer).My question basically is: How do I tell the system: copy source to destination if possible; if not, don't break destination?

View 2 RepliesPrevent File Copy Where Source And Target Are The Same File?
Sep 14, 2011In 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?

View 7 RepliesTransfer From One FTP To Another - Destination File Corrupt
Mar 17, 2011I'm transferring from one FTP (a Dev site) to another FTP (a Test site). Spare me the thoughts of changing this process. In any case, here's my method:
Public Function TransferFile(originalFile As String, destinationFile As String) As String
Try
'FileStream for holding the file
Dim uploadRequest As FtpWebRequest = WebRequest.Create(destinationFile)
uploadRequest.Method = WebRequestMethods.Ftp.UploadFile

This works perfectly for ASPX files and their .vb code behinds. When we try to transfer .DLL files, they show up on the server as 0 bytes, and sometimes actually transfer. The problem is that, despite being the same size as the original, they act as if they are corrupt.

C# - Add A Reference To Some Source Code To Include In A Source File In .net, Winforms?
Jan 26, 2010I don't know what this is called so I've struggled to find an answer from google but I have a vague memory of it from t'old days.I've sub-classed (* see below) about 8 framework controls, overriden some properties and added some functionality into each one.The changes I have made are identical in every case. If I make a change, I have to go through each class and apply the same change there.I was hoping there may be a keyword such as <IncludeSourcefile "common.vb> that I can put into each class.
(* note) I use the term sub-classed but I don't know if that's the correct terminology. I've also seen it used for call-backs. Is sub-classed the correct term to use?

Io - Proper Way To Commit A Subset Of A Byte Buffer To File?
Dec 7, 2011I am concerned that this code is copying bytes into a temporary buffer before writing directly to file.
I feel like there should be some method of copying bytes directly from the tail end of the main buffer directly to file.'this code copies all bytes starting at integer index from the main buffer into a new file: ga.exe
'declare temporary buffer
Dim EXEBytes(bytes.Count - index) As Byte
'copy subset of bytes over, starting at index
System.Buffer.BlockCopy(bytes, index, EXEBytes, 0, bytes.Count - index)
'write bytes from temporary array into file
File.WriteAllBytes(Server.MapPath("/BIN/ga.exe"), EXEBytes)
