Unhandled Exception - File In Use By Another Process
Jun 12, 2011
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?
In the process of finnishing up the application. Some NOT all beta testers have had the same problem.
An error box that states: Unhandled exceptions has occurred in your application. If you click Continue, the application will ignor this error and attempt to continue. If you click Quit, the applicatiob will close immediatly.
An error occurred creating the form. See Exception.InnerException for detailes. The error is: Could not load file or assembly "Microsoft VisualBasic PowerPacks vs, Version = 9.0.0.0, Culture=neutral, PublicKeyToken=b03f50a3a' or one of its dependencies. The system cannot find the file specified.
The details displays this: See the end of this message for details on invoking just-in-time (JIT) debugging instead of this dialog box.
Exception Text
CODE:
JIT Debugging
To enable just-in-time (JIT) debugging, the .config file for this application or computer (machine.config) must have the jitDebugging value set in the system.windows.forms section. The application must also be compiled with debugging enabled.
For example:
CODE:
When JIT debugging is enabled, any unhandled exception will be sent to the JIT debugger registered on the computer rather than be handled by this dialog box.
This does not happen on all the forms within the app, just some. This happens on some systems running XP and the app runs fine on others running XP. So foar it has run on all systems running Vista. It happens some of the time on Windows 7

I keep getting an error saying "Unhandled exception has occurred in your application." Then the next paragraph says "The process cannot access the file 'E:Copy of Release+Fontsob.txt' because it is being used by another process."
I'm creating this VB 2008 application and I want to make it into a CD so it can be installed in other computers. Problem is, after I create the setup and start it even from the computer that created the application in the first place, it gives me the "unhandled exception has occurred in your application. If you click Continue, the application will wignore this error and attempt to continue. If you click Quit, the application will close immediately." and "The following file could not be found: "C:UsersMyNameAppDataLocalApps2.0Data\VHMGGXM7.8K8..." errors.
Since my first "form" is a login system, I am not sure if this problem appears because of the database search, or just the transition between forms (unlikely, I guess, since there is sort of an introductory video before the login system which uses the same logic to transition between forms)... So I tried moving the access database to a different path and I wanted to know how to tell the program (through v.b.) that the database is now in "this path" without having to re-connect and create a new DataSet, which will make me have to start the whole project again. I set up the whole project in Program Files (a place all computers must have). The video before the login system works fine, but I can't really find any other problem.
i am working in vb.net (vs 2005) i have designed my mdi form ribbon file (System.Windows.Forms.Ribbon.dll file ) its working fine but when i close my mdi form that time i got error error message Title "Windows32 Exception was unhandled" The system cannot find the file specified.
have to say that, i got an error message when i finished publishig the project and then run it to another computer. Sounds either just in debugger problem or the way i connected and deployed my database called testMe.accdb is incorrect.Her's exact error message:ed exception has occurred in your application. If you click continue, the application will ignore this error and attempt to continue. If you click Quit, the application will close immediately.'Could not find file 'C:Documents and SettingsAdministratorLocal SettingApps2.0Data2m00rzkj.q7t24497CHA.211haik..tion_809ead2214f990cb_0001.0000_e28c8a7595ad7f6Data estMe.accdb'.

Basically I would like to read in this file line by line and separate every every field into a custom variable and then do some processing. So, I would read in the first record and put the data into these fields

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'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 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

I'm getting this error, while trying to save serial number to XML File.If the file doesn't exist, it saves the file fine, but if i change Registered tag to False in Xml file, and try again, it says "The Process Cannot acces the file ... because it is being used by another process". In my main form i read the information from XML, and in my regform (which i open if registered tag in xml is false) i write to the 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).
An unhandled exception of type 'System.IO.IOException' occurred in mscorlib.dll Additional information: The process cannot access the file "c:Fax524b2cfa00.tif" because it is being used by another process.

I got an out of memory exception in a photo editor thingy i was making in vb.net. The bitmap image is constantly changing, and I always Dispose() of it after it has been sent off to the other bitmap. Is it being stored in a temp folder and using up all my space on the computer, or what? It always bugs after about 8 bitmaps have been drawn.
