VS 2005 - Error: File Being Used By Another Process
Mar 18, 2009
I'm trying to delete a file, which prompts the error: "can not delete File in use by another process". I've been researching this for the last couple of days, and have tried every possible suggestion, I've come across, but still keep getting the error. I'm hoping someone might have a suggestion on what I need to change or rearrange in my code to get around this.
The program loads a group of files into a listbox, user selects which files to process, Each file is sent through the sub (process files) to be renamed, and then processed through external programs then removed from the listbox. Each file in the list HAS to be renamed the same in order for the external program to process it. This is where I'm getting the error message, as I need to delete the previous file before renaming the new one. Parts of my code may seem redundant, but its where I was trying every possible scenario of closing the process and or stream that's leaving the file open. [Code]

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.

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 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).

Lets just say I had something like this:
System.IO.File.Create("C:.txt")
Dim SaveF As New System.IO.StreamWriter("C:.txt")
Under each other. It gives me a error saying:
The process cannot access the file "C:.txt" because it is being used by another process.

I am trying to create an MDB as a temp file to save some tables and query them. After creating, I can't delete it ... Even before it is actually used. The process cannot access the file because it is being used by another process.
Dim mdbFileName As String = System.IO.Path.GetTempFileName
Dim objClassType As Type = Type.GetTypeFromProgID("ADOX.Catalog")
Dim obj As Object = Activator.CreateInstance(objClassType)
obj.[GetType]().InvokeMember("Create", System.Reflection.BindingFlags.InvokeMethod, Nothing, obj, New Object() {"Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" & mdbFileName & ";"})
[Code] .....
This MDB (after all operations) is huge (+200 Mb) and needs to be deleted.

To summarize, my program uses a textbox to display the chatroom from a text file on the school network. When someone sends a message, it writes that message to the text box like so:My.Computer.FileSystem.WriteAllText(baseDir & room & ".txt", Message, True)
The baseDir is where the chat files are stored, and the room that the user is in can be altered by the user. created a scroll bar to use so when the chat room reaches a certain length of lines, you may use a scroll bar to view the whole chat. I realized that when someone sends a new message, the scroll bar then jumps back to the top of the text box. Is there any way to fix this, so that it will jump to the bottom each time someone types something new?
Dim lines As String() = IO.File.ReadAllLines(baseDir & room & ".txt")
Dim numLines As Integer = lines.Length
If numLines > 20 Then

I'm making a program that gets the hash of anything that is downloaded from the internet. I used a filesystemwatcher to watch the "C:Users" & Environment.UserName & AppDataLocalMicrosoftWindowsTemporary Internet FilesLowContent.IE5" folder.

I'm writing a little program where I select a picture through an open file dialogue. When I selected a picture I want it to overwrite the current picture and display the new image. Now I don't have any problems with picking an image with a different extension. So when I currently have a .png I can select a .jpg but when I choose an image with the same extension as the current image I get an error: The process cannot access the file 'C:Users....woontypeimageschalet_foto.jpg' because it is being used by another process.

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")

I have an issue using Process.MainWindowTitle,Process.MainWindowHandle on some older VB6 applications. After Process.Start I use Process.MainWindowTitle to display in a listbox. The MainWindowTitle returned is not the Window Title but in fact the Project name of the VB6 exe.? I also store the MainWindowHandle to use the ShowWindow and SetForeGroundWindow API's. It would appear that the ShowWindow API does not work, but the SetForegroundWindow does. ie: if the VB6 app is minimized, showwindow does not restore, if it is NOT minimized setforewgroundwindow sets it to the foreground. The exact same code does work correctly for any other .net exe or notepad, only on these vb6 programs I am having a problem.

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 am working on a small VB application that listens for commands sent from an Android app.
One of the functions is to extract an archive. I am familiar with how to listen for the unrar process to finish, so I can display a progressdialog on the phone while the extraction is happening, and clear it as soon as it's done.
BUT ... if there is an error/alert from WinRAR, WaitForExit() never gets called because WinRAR is still sitting there open until I click "OK" on the MsgBox.
For Example ... if you try to extract a file that is not actually an archive... an alert will pop up saying "No Archives Found", and basically everything is halted on the VB app and the Android app, and the Android app just sits on a progressdialog saying "extracting..." until you manually hit "OK" on the computer.
As you can imagine, this is a problem if the whole point of your app is to NOT have to go over to the computer.
So... I am wondering if there is something similar to WaitForExit() that will wait for an error and allow me to close out the alert and let the process end.
Here's my Sub for the UnRar command:
Private Sub UnRar(ByVal WorkingDirectory As String, ByVal filepath As String)
Dim objRegKey As RegistryKey
objRegKey = Registry.ClassesRoot.OpenSubKey("WinRARShellOpenCommand")
