It seems like FileSystem.GetFiles() is unable to recover from the UnauthorizedAccessException exception that .Net triggers when trying to access an off-limit directory.In this case, does it mean this class/method isn't useful when scanning a whole drive and I should use some other solution (in which case: Which one?)? Here's some code to show the issue:
Private Sub bgrLongProcess_DoWork(ByVal sender As System.Object, ByVal e As System.ComponentModel.DoWorkEventArgs) Handles bgrLongProcess.DoWork

If I have a folder with a bunch of ".htm" & ".html" files in it and I use
My.Computer.FileSystem.GetFiles(myFolder, FileIO.SearchOption.SearchTopLevelOnly, "*.html")it returns all the ".html" files, as expected. But if I useMy.Computer.FileSystem.GetFiles(myFolder, FileIO.SearchOption.SearchTopLevelOnly, "*.htm")it returns ".htm" & ".html" files, when I would expect it to return only the ".htm" files. Is this a bug?
My.Computer.FileSystem.GetFiles(My.Computer.FileSystem.SpecialDirectories.ProgramFiles, FileIO.SearchOption.SearchAllSubDirectories, "MSAccess.exe") or
Consider the following snippet: Dim Arext() = {"*.ttf","*.ttc"} For Each foundFile In FileSystem.GetFiles(srcdir, SearchOption.SearchTopLevelOnly, arExt)
[code]....
The unexpected result is that not all the files specified in arext() are returned by this code. Running the same code twice on the same subset of files does NOT produce consistent results.I'm seeing, probably, 90% of the files with the other 10% not being included?
Do you know how to declare a variable that can hold the result of a call to GetFiles?
I don't know how to do this, so I am using the following verbose/duplicative version: Dim l_v_String_FoundFile As String If My.Computer.FileSystem.GetFiles("A:u_Au_W", FileIO.SearchOption.SearchAllSubDirectories,

This has to be simple, but can't find the answer.I want to display a list of all files from a folder in a listbox. Easy..., but I want to display only the filenames without their paths.
For Each foundFile As String In My.Computer.FileSystem.GetFiles("C:My Folder") ListBox1.Items.Add(foundFile) Next This gives me list looking like that: C:My Folderfile1.txt C:My Folderfile2.txt
Dim filePath As String = "~/Images/FleaMarket/uploadedImages/" & User.Identity.Name.ToString & "/" & itemID & Path.GetExtension(fuImage.FileName) MsgBox(filePath)

I get an error "System.UnauthorizedAccessException: Access to the path 'D:TriceDealsII Updated13-10-11Tricedeals II(4)ImagesFleaMarketuploadedImagesmitali2054' is denied"
I searched for that error but got nothing.. strange.. so I'll ask..ok I have some code that I'm using to open MP3's and change the titles so I dont have to listen to audiobooks out of order....got this code from the web.. <below>I got it to open one.. and see all the tag's etc.. now I wanted to change oneof them.. but when it opens it.. I get that permission error.. the file is in c:/users/kevin and the file has permissions like normal.. but it wont letme open it..this is the open command its trying..FileOpen(intFile, mstrFilename, OpenMode.Binary, OpenAccess.ReadWrite, OpenShare.LockWriteEven tried changin the UAC settings to full priv.. that didnt work.
im trying to search my hard drive for jpg files and it works great except for when it hits a system file, i have admin access. I tried try/catch but it didn't work for me. All i need it to do is skip that file that is denied access. [Code]
im having some issues with getfiles, and i cant seem to pin point the cause, heres the issue:Im scanning a folder which has a mix of file types (.7z, .rar, .bin) and for each file im checking a dat file to see if that file (via the crc32) is listed in the dat. Pretty simple, but my code is randomly hit/missing heres what i have around my vb For Each strFile As String In System.IO.Directory.GetFiles(ComboBox1.Text, "*.*", SearchOption.AllDirectories)Next ComboBox1 .Text is a folder path for example 'C: est'
And inside of that i hae the crc32 code, the crc 32 code works great, the issue is with the above so no need to post lots of crc32 code. Now the problem im having is say i scan a folder with 10 files, lets say 5 7z's and 5 .bin's, sometimes the scan will scan all 10 files sometimes only 5 7z's and 1.bin, sometimes no .bins, sometimes only the .bins.If i put the .bins in a folder on there own and scan it will scan them all, same with the 7z's, so why is it not working when there all in the same folder?EDIT: I think the error is here 'SearchOption.AllDirectories' but i dont understand how to fix it, if i put all files into the root of the folder it will scan all of them, but i wanted to be able to scan the files in the subfolders to hence the SearchOption.All Directories, but it seem to be failing
I have a function that returns a value of the numbers of files, folders and subfolders in a directory. But i can't seem to handle the "UnauthorizedAccessException" which i get from certain read only files or folders. I tried to use both the DirectoryInfo.GetDirectories() and DirectoryInfo.GetFiles() methods. as you can see from the code below. This exception is thrown in start of the for each loop, so i'm not able to handel it with a try, Catch Ex As UnauthorizedAccessException to cintinue the loop.
Is there any way to avoid UnauthorizedAccessException, i get it every time when I try to do this:[code]Is there any way to make that script read-write?
I am trying to search a drive letter (C drive) for a file in Vb.Net 2010. After I find the file path I want to run the executable. This is the code I am trying to use to find the file:
System.UnauthorizedAccessException was unhandled. I'm following motcom's tutorial on creating a simple directory explorer, and everytime I try to expand I get the error above. How can I be getting that error on my own computer ? I'm on my administrator account, it happens even if I compile it and run it as administrator also. What could be causuing this ?
i am creating an application that needs to read a text file from an external hard drive, the paths etc are all correct however i am getting the error System.UnauthorizedAccessException"i have searched through various forums and googled it and the only solution i can find is to allow the .net user permissions however i dont have this user/group on my system.also i am using Windows 7, dont know if that should make a difference.

I am making a client/server project where the server can send a String variable to client but for now i'm starting with a simpler code. I was able to code a bit but now i'm having a problem with this UnauthorizedAccessException. It seems that I am not authenticated but i was able to put the admin username and its password. This is my problem.. Here's my code...
I want to search an string in all files on C:.For this I use list = My.Computer.FileSystem.FindInFiles("C:", "Bula Bula", CaseSensitive, SubDirectorys)So when the search come to "c:Documents and Settings" for example I get this error:
System.UnauthorizedAccessException was unhandled Message="Der Zugriff auf den Pfad "c:Documents and Settings" wurde verweigert." Source="mscorlib"
I'm using My.Computer.Filesystem.WriteAllBytes to write out an executable stored in my application's resources to it's startup directory. After running the executable, I then delete it. Everything works fine; however, I'll randomly get an UnauthorizedAccessException for no reason. After getting the exception, I can manually delete the file with no problem. Here's the full code:
' Convert MP3 ' First, copy out converter Dim Path = New IO.FileInfo(SoundPath)
[code]....
What perplexes me is that I literally just wrote out the executable, and nothing else could possibly be using it. I've checked the file attributes and it's not read-only. My application is also running as an administrator.
I am using VB.NET 2008 Express Edition to access Serial Port which is a USB to Serial port. Since this is removable, the app user can disconnect it at any time in app. I am getting an unhandled exception when I remove the USB Serial Port.
My application needs to change the default signature of outlook and I need to change the value of a registry key for this. But I get a error that I probaly don't have enough permissions. Strange thing is, if I change it manually it doesn't complain.
Error:System.UnauthorizedAccessException : Cannot write to the registry key.
In my VB.NEt 2008 application, I am frequently creating and killing the file Fileopen and Kill(Multiple times ). It was working fine with Windows XP. But in Windows 7, it is worjking fine for some time (creating and killing theile properly) and then t is creating unautoriszed Access exception after some time .it does not happen immediately and it happens intermittently.
Sampel code is as give below: Publicl_filenumber as Integer Procedure 1:
