IO Exception "The Process Cannot Access The File Because It Is Being Used By Another Process"
Jul 17, 2011
My.Computer.FileSystem.Rename(pathname,name) < < Throws the above exception I am trying to rename a small .jpg image, - previously (in this application program flow) accessed by the following:
btmp = New Bitmap(pathname) < < , and was followed by a btmp.Dispose well before the Rename called it. Plenty of time had gone by. But for some reason the "application process" is not releasing the pathname for me to rename or delete it.

How can i access a file through FileStream which is being used by a window service. Actually i am trying to access a file which is also being used by our window service. I need to read data from this file. I am using below code but also getting following error:
Code:
Dim fs1 As IO.FileStream = New IO.FileStream(psPath, IO.FileMode.Open, IO.FileAccess.Read, IO.FileShare.Read)
Dim sr As IO.StreamReader = New IO.StreamReader(fs1)
sData = sr.ReadToEnd
Error: The process cannot access the file 'FILENAME' because it is being used by another process.
I tried changing FileShare.Read parameter to FileShare.None but it didn't work out. I also read below post which says that it is not possible but i think there is a way to read it like if you open a file through Firefox but still window service is accessing it.

I am working with saving and deleting images. What i really want to do is check and see if an image exists in the destination folder and if it does automatically overwrite it. i couldnt figure that out so i figured i would look to see if the file was there if it is Delete it then write the new file..The issue is i keep getting this error.The process cannot access the file "FileName" because it is being used by another process.

The process cannot access the file 'C:UsersJoshuaDocumentsTest1.txt' because it is being used by another process.Now the Problem. When i step through my code, it will do as intended, e.g. clear all contents of test1.txt. when i run it at run time it throws this error. The reason for it throwing an error is the text file is reading string, int, string, and the txt file has a string including in the int part, so i'm making it so you can empty a corrupt file.

When I load my solution and compile it after first starting the IDE, everything works as expected. After changing source and recompiling, I get the following compile error:
Error 11 Unable to copy file "objDebugCAMDRS.Library.dll" to "binCAMDRS.Library.dll". The process cannot access the file 'binCAMDRS.Library.dll' because it is being used by another process. CAMDRS.Library.
After closing Visual Studio 2005 and reopening the solution I can compile again successfully. This is an old solution that has been fine for a long time. I just recently changed computers and reinstalled everything.I am running win XP Pro sp2, Visual Studio 2005 sp1.

My program writes to a .txt file (and this is the ONLY program that writes to it) in a thread (with lowest priority), but every now and then it gets an error "The process cannot access the file because another process has locked a portion of the file" when it executes this code: swLog.WriteLine(sPacket).Other program reads from the file, not write to it, why do I get this error, and how can I get around it, or what shall I do when I get this error since I can't write to the file ?

I have created a Windows service in VS 2005 that monitors a folder for XML files, reads some data elements from the XML using XmlDocument, then copies the files to another location. I find that when I drop 2 or more XML files into the folder simultaneously, it processes them with no problems, but when I drop the same files into the folder one at a time, I will get an error on the second file: "The process cannot access the file <my file> because it is being used by another process." If I stop my service, restart it, and drop the second file into the folder again, it works the second time. I am confident that no other program is accessing this file at the same time as my service. My impression is that the processing of file # 1 is somehow not releasing all of the resources, leading to the processing of file # 2 mistakenly thinking that it can't access that second file.

In VB.NET or C#, I'm trying to read the contents of a text file that is in use by another program (that's the point, actually, I can't stop the program or it stops writing to the text file, and I want to periodically read out what is currently in the text file in another program)[code]in VB the code is above (a C# answer would be fine as well), however, it still throws the IO exception "The process cannot access the file 'file.txt' because it is being used by another process." Are there any workarounds in this scenario?

I am writing a program that creates a file and attaches it to an email. I use a loop to create the attachment, send the email and then do it again with different information in the attachment. This works well for one tim through the loop, but on the second time through I get an error when I try to open the file for output to create the new version of the file. I get an unhandled exception of "The process cannot access the file 'c:ProjectArticles1Article.txt' because it is being used by another process.". How can I release the file from being used once the email has been sent?

I'm trying to build a program updater based around downloading XML files from a server. The idea being that the servers XML file contains the current version number and installer location. the updater either gets dumped in the startup folder or gets installed as a service, etc. The program successfully reads and parses the current version xml file and it successfully downloads the xml file from the server.
However when I try to parse the newly downloaded file from the server I get the error:
'IOException was unhandled'
'The process cannot access the file 'C:Program Files (x86)TestServerVersion.xml' because it is being used by another process.'
The code is as follows with the error marked by a comment on line 52:
Imports System.IO
Imports System.Xml.XmlTextReader
Imports System.Net
Module Module1
[Code] .....
It's still work in progress but there's not much point in writing code to download and execute the installer if I can't work out the location of the new version. In case it's of use here is the XML:
<?xml version="1.0" encoding="UTF-8"?>
<VersionConfig>
<AvailableVersion>2.0.0.0</AvailableVersion>
<ApplicationUrl>http://192.168.2.226/EPI/2.0.0.0/</ApplicationUrl>
</VersionConfig>

I have written a windows service that is meant to launch a notepad when a specific action happens. The problem i have is that even though the service launches notepad, the actual notepad it self is NOT visible. I know that it has been launced because i can see the process in the task manager. By the way the process is listed as a SYSTEM process rather than a process under my user name (i believe that is because my process is a "LocalSystem" one).

I have been searching throughout the forums and have yet to find an answer that will work for resolving the above problem in my program The exception is occurring within the declaration of a new streamwriter and after the closing of a previously used streamreader that accessed the same file I'm trying to write to. I think that the file is completely closed at the end of the streamreader block, but I cannot tell for sure.
This bit of code is the block just before the streamwriter declaration and the declaration itself:
Dim fn As Integer = 1 'first number for searching for file

Am trying to achieve a couple of things: merge a bunch of individual text files into a combined file, move the files that were combined into a new folder. I have assigned each of these tasks to a method. Something in the first method is hanging on to the file, even though I am closing and disposing the stream reader - but I can't figure out what. I know that a process from the first method is hanging on to the file because when I comment out the first method, the second method moves the files without a problem.
EDIT The first method is returning a value for new big file. This is passed as a parameter to the second method. When the second method tries to reference this file, that is when the program throws the error (5th line from bottom) Most posts on SO advise closing/disposing IO objects, but I am already doing that. They also advise using a third party tool to investigate what process is hanging on to a file, but I already know that it is the first merge method (because when it is commented out the program runs).

I have made a small program which loads a file into a listview when somebody presses the load button on the form. The user can also put information in the listview by filling in some textboxes and press on the add button.So now the weird thing is that if the user loads an empty file ( With no information in it ) and presses load on the form and after that tries to add information to the file you get a "The process cannot access the file '" because it is being used by another process" error.
The code for the load button is as followed: ( So here accountfile 2 is loaded )

I have a problem and have tried several attempts to remedy, but have not figured out a "robust" fix. my problem is I randomly get the "process cannot access the file ??? because it is being used by another process".What I am doing is reading a text file about every 1/2 second. later in my app i try to write to the same text file.
Question: is there a way that i can read the text file without causing this error?

I have some coding which edits my text file and saves two versions, the first version removes all multiple space with one space and saves it as a text file and the second replaces the spaces with a comma and saves it as a csv file. The problem I have is however later on when I run other code using the saved text and csv files, it looks like the processes are in use. I get the following error:
The process cannot access the file 'Path' because it is being used by another process.My actual coding:
Private OpenFileName As String = IO.Path.Combine(Application.StartupPath, "TextFile1.txt")
Private SaveFileName As String = IO.Path.Combine(Application.StartupPath, "TextFile2.txt")
Private SaveFileName2 As String = IO.Path.Combine(Application.StartupPath, "TextFile3.csv")
