File Cannot Be Accessed As Another Process Is Accessing File
Mar 10, 2009
I've been stuck on this for 3 days now.I have a TiffBitmapDecoder accessing a file and generating a BitmapSource from one of the frames in the file. If I try and modify the file after that e.g. insert new frame or even delete file, I'm informed that the file cannot be accessed as another process is accessing the file.How do I either a) Get the TiffBitmapDecoder to release the file or B) force all processes that have access to a file to release?Note: I'm using WPF and the TiffBitmapDecoder does not have standard fileStream methods like close, dispose or flush.

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

If you need more info or more code chunks to help solve the problem, feel free to ask

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 am developing an application in VB.NET. in which I need to open the most recently accessed file (i.e. last accessed file in the previous session) when the application starts. One approach is to save the location of the most recently accessed file in a text file and read it when the application runs the next time.

I am working on a file access monitor wrapped up in a VB .Net Class. The ileSystemWatcher is working and my log file shows files when they are accessed. However, I am having trouble returning who or what accessed the files. For example....system services and processes should return something like NT-ATHORITYSYSTEM while a network share being accessed by another computer should return DOMAINUSERNAME and finally a process running in the background via "Switch User" should be returned as DOMAINSOMEOTHERUSER ....anybody have any ideas? I have searched high and low and have found nothing but other people asking the same question and people saying how it is not possible. the Sysinternals Process Monitor is able to output the correct results and its documentation states it was created using NET API however I can not find any references to any such API calls or combination of such. Should I be using something else other than the FileSystemWatcher? My code is below

I am brand new to VB and been advised it might be the best thing to use for my problem, so here goes. I need to be able to scan a machine for all excel and access db files and list them by name and last accessed time. I would like to be able to do this in bulk so more than 1 machine at a time but thinking it my be best to do each machine seperately.
When I have the data I need it to be exported in a list to either excel or a text file or anything really. Als if possible how would I add the machine name to the list so I know which one i have scanned. I have been searching the forums and google but think I am getting more confussed as this is a whole new world for me.

File.copy works.But somehow, a message saying oldPathName is being used by another process, when it tries to delete the old 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 have read a log file which is being used by a process. I could open the file in notepad or similar applications. The log file is not written by my application.
File.Open or streamreader gives me the following error: "An unhandled exception of type 'System.IO. IOException' occurred in mscorlib.dll. Additional information: The process cannot access the file "E:parkvbproject1.NETinsystem_log" 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.

I Am a new developer in VS 2008. I am writing a small program that reads an XML file. Here is a snipet of code.
filename =
"XMLPolicyList.xml"
Dim DR As XmlTextReader = Nothing
[code]....
My understaning is that the system looks for the file in the bin/debug folder, so that is where I put it. But when executing this program. I always get a FileNotFoundException. The file name displayed is (filename). If I hard code the entire directory name and file name I get the same error and the file name is displayed with the same slash in front of it. For instance I put the file on the C drive and the error displayed C:(filename).I don't have the problem in older versions of Visual Studio. The same program runs fine in VS 2003. I'm thinking that there must be some sort of setting within VS 2008, but I have been unable to find it.

I'm running VB2005 and have an application where an operator can save a snapshot of an image in a picturebox as a jpg. They can call up any jpg they want and display it in another picturebox. The issue is that if there is an existing file and the operator loads it into the 2nd picturebox, the operator isn't able to overwrite this image file from whatever is in the 1st picturebox.

I have an external project (DLL) that I have referenced in my project. One of the requirements of using that DLL is to include an XML file in the same directory as the DLL. Now I know in a production environment I could just add that DLL to the GAC and place the XML file in that same folder. However, that doesn't help me when I'm trying to debug it. I have tried including it into the BIN directory but it never gets moved to the Temp directory when compiled.

I was wondering if there is any way to manipulate layers of a psd from within a VB program. I would Ideally like to inserts just the psd file in and then once a command is clicked turn one of the layers on or off.
I know I can accomplish this inserting a jpg/gif for each layer and have that image be turned on or off by a button click, but I figured using the psd would save room and if something needs to be aligned differently I can just make a change in photoshop. Opposed to trying to realign the coordinates in VB
