Using OpenFiledialog I can access a file. Is there a way that I can include a specific file in the code? This would allow me to access the file directly without the selection process and the application would always use that same 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 ?

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.

View 2 RepliesThe 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.

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.

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")
