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 using a thread to call a process which is spliting a text file into various text file and folder using the system.io , now when calling the Textsplit() with thread on click of a button i am getting the error below , how to use thread and why this error occurs.

I'm trying to write text to / read text from a file, but when it's trying to execute the My.Computer.FileSystem.WriteAllText code, it throws an exception: "The process cannot access to the file "<filename>" because it's being used by another process", and the "source" of the exception is "mscorlib"Note: this is a DLL file, which is being used by an application.
I tried to use:

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.

View 4 RepliesI'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]

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.

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'm trying to use VB.NET to process a very large plain text file (2 GB). It is a database and has a field delimiter of SOH and a record delimiter of STX.
I want to separate the fields and records of the file.
I would normally read each line of a text file and then use the split function to separate out the fields. I can't use this approach as there isn't always a delimiter on every line.
Is there any way to read a file until STX is found (rather than one line at a time)?
I have a log file that is open and in use by another program, and I read it's contents with the following:[code]This works for reading the text from the file while it is still in use by the other program, however, immediately after this I need to truncate the text file (without deleting it) so that it is blank again. But the file will still be in use by the other program.[code]But I get the "in use by another application" exception. I've tried looking in StackOverflow and googling but I can't seem to find an answer, and I can't find a way to do this with filestreams either, or I would try to use Dim fs As New FileStream(FullPath, FileMode.Open, FileAccess.Write, FileShare.ReadWrite)
View 4 RepliesI am trying to create a program that will refresh a *.log file within the program itself (in a RichTextBox), but while the actual application that is writing to that *.log file is open and is utilizing that file as well.
I have tried multiple things with StreamReader, but I can't seem to get anywhere...
Simply, I want to be able to read a *.log file in my Visual Basic 2010 program, but while the actual application that is writing to it is running itself.
How can I do this, as I keep getting the error that another process is utilizing the *.log/text document?
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 )

View 2 RepliesI 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")

I am trying to automate a process I do with a bank with vb.net. Basically I need to open a website and navigate through it (Automatically through the program obviously), enter a batch ID and enter a file path and name. For some reason when I get to the part where I need to enter the file name and path, it simply will not populate the text. I have attached a word document with screenshots and code. The only difference I can see, is that in the bank website's code the the input type for the file text is "FILE" rather than "TEXT" as it is for the batch id...
