VS 2008 System.UnauthorizedAccessException Missing Path?
Mar 18, 2009
Ok so I have a small problem with an error I am catching. It only produces the file name and not the actual path of the file.I want to delete a folder and all the files and folders inside of it. However an error is thrown when a file is "read-only". A quick fix would be to set the attributes of that file to normal and then try again, the only problem is the error doesn't give you the location of the file.
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:
This is a slightly tricky one, so bear with me...I have a simple little method:
[code]...
the service is for now working correctly. Anyone have any ideas what would cause such an intermittent failing? I'm assured by co-workers that nothing was changed over the weekend (not manually at least). Baffled...
I'm running windows 7 64 bit and using VS 2010. I'm trying to use the filesystem.getfiles to find a file on the computer and return the path for it. However, when I search C:/ and its subdirectories, it always throws an error: "A first chance exception of type 'System.UnauthorizedAccessException' occurred in mscorlib.dll"
I've looked everyone online and can't find a solution. I have administrator privileges and really I dont want people who use my app to have to adjust security settings for this to work. Is there not a way to search the C drive for a specific file and return its path? [Code]
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.
Public Class frmMain Public Structure Movie Public Name As String
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.
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 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 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.
I am running vs 2008 and and trying to connect to an sql server 2005 to do userauthentication, but the error message i get is"Access to the registry key 'HKEY_LOCAL_MACHINESOFTWARESmartinfoLibServer' is denied" and the message "A first chance exception of type 'System.UnauthorizedAccessException' occurred in mscorlib.dll" also shows in the immediate window.
I am using an existing COM dll that works fine in VB6, on the same development machine. The VB6 app compiles and uses this dll without issue.
I start from scratch to design a new Windows Form application in VB.Net. Then when I try to add a reference to this dll, the reference is added to the references list but the path shows as <The system cannot find the reference specified>. If I select this reference in the list, the properties window shows a blank for both the reference name and the path. At the same time, a reference is added for VBA, and it shows the reference name (Interop.VBA) and path correctly.
I used dependencywalker to find the dependencies for this dll. It has 3: user32.dll, kernel32.dll, and msvbvm60.dll. So presumably I have all necessary dependent files.
I have tried un-registering, re-registering the dll. I have tried the command line switches for devenv.exe to reset settings and to launch in safe mode. I created a new user account to see if it was related.
I have tried picking the dll from the Add References, COM tab and also via the Browse tab to select the file directly. Same result all cases. I also tried putting the dll and msvbvm60.dll in my bin folder.
I don't understand how the reference name and path are missing in the properties window when the reference name is right there in the list and I select the path directly when I added it. There are no other instances of this dll registered.
I tried using tlbimp from the command prompt with verbose switch, I get the error: System.Runtime.InteropServices.COMException - Error loading library/DLL. (Exception from HRESULT: 0x80029C4A (TYPE_E_CANTLOADLIBRAY)). I wish it would tell us what is missing.
It must be registered properly and all dependencies available for it to work in my VB6 app, Re-writing the dll is not currently an option.
Im trying to tell my button to go directly to a website, it works fine when i path it to the web browser itself, but then when i add it to go to the sppecific site it says system cannot specify file path. Heres the code Rob gave me and it didnt work ""[URL]""" Heres my exact line: Process.Start("C:Program FilesFlockFlock.exe ""[URL]"")
I have been getting a lot of crash reports sent from my application that describe System.Web not being found.
I was able to reproduce the problem, and at first it seems that it would be caused by not running .NET 4.0, however, my test machine is running Windows 7 SP1 with .NET 4.0,
How would I go about fixing this problem? Was System.Web deprecated?
I'm coding this neat little project that's kind of a hack into the SanDisk U3 Cruzer's ability to have both a CDFS and FAT32 File System. This is helpful because the program is burned to the CDFS (It's basically slip streamed as an .ISO in place of the original U3 .ISO), and the settings files (which I've developed as text files) are placed on the root of the flash drive. The program itself is VERY simple actually, except I'm having a slight issue that's really driving me insane:
The drive path of the Flash Drive won't be the same from computer to computer. I.E... The files are "UAI.txt" and "UInfo.txt". The root of the drive on my comp is "I:", but on my laptop is "F:". So if I program the path from my computer as the absolute path, an exception is thrown when the path changes on another computer. I cannot have this happen. It is probably THE MOST crucial element to this program. How can you save and read info if you can't find the files? =P
So I've gone through so many threads and forums trying to find a batch of code to allow me to make the path relative. I've found the following code (modified, of course). It works PERFECT in Debug, but throws an exception once packaged to the CDFS partition:
I must be missing something very obvious...Using Visual Studio 2005 to write a vb app for Windows CE. I'm trying to use the NetworkInformation namespace of System. I can see it in my object browser, but when I try to use it in my form, it doesn't come up in the autocomplete and the compiler complains that "NetworkInformation is not a member of Net".
I am trying to execute a VB .net console application called Application1 that I created using Visual Studio 2008 with .net framework 3.5. When I run it under the windows scheduler or from a command prompt it works fine. When I try to run it under a purchased job scheduler, I get a message stating that directory APPLIC~1.config is missing. What properties does system.configuration use when it tries to find an application's .config file? Can these be set when my application starts?
Note: I was able to use ConfigurationManager.OpenExeConfiguration(My.Application.Info.DirectoryPath & "" & My.Application.Info.AssemblyName & ".exe") to get around this issue but would like a cleaner solution. I do not want to do this each time I want to retrieve an appSetting entry.
#1 is C# Class Library, where I have my EF model defined (3.5 sp1) and some public methods.#2 is a VB winforms app.In the winforms app, I have referenced the C# library and added the connection string for the EF model. The problem I am having is that I have a form where the user selected a .txt file to import. On the VB side, I create a byte() from the file, then pass it to a public method cleverly called Process. In Process(), everything runs smoothly until I instantiate the EF model.

I have tried several versions of this with no luck. The casting of the worksheet works as my data is entered in other parts, but I have a section where I need to add data 1 column right of the cell containing the 'str(0)' value. Most of these parameters are optional. I have even tried the System.Reflection.Missing object.
I thought the %AppData% should find the relative path. When I go 'Start|Run|%AppData% windows explorer takes me to that directory. I can not put the full path in, as the user is different on each client machine.
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.
