Help with permission settings for System.IO.File.Copy?

Posted By:      Posted Date: October 10, 2010    Points: 0   Category :.NET Framework

I have a vb.net 2010 program in ms vb express '10 for copying files from the root directory of the Documents folder to either an SD card in a reader or a flash stick but when I run it throws this exception: A first chance exception of type 'System.UnauthorizedAccessException' occurred in mscorlib.dll

Here is the underlying code:

Public Class Copyto
  Shadows Sub SdBackup()
    Dim Hdrive As String
    Hdrive = "H:"
    Dim Origin As String
    Origin = My.Settings.UserDocs
    System.IO.File.Copy(Origin, Hdrive)
  End Sub

  Sub FormLoad() Handles MyBase.Load
    My.Settings.UserDocs = My.Computer.FileSystem.SpecialDirectories.MyDocuments

Downloading a document from a sharepoint site to local file system, copy web service returns null

Hi Guys,
               I am trying to get this done for the last 2 days and I am still banging my head to the wall.
All I need to do is to download files from my sharepoint site library that uses integrated windows authentication. I was using copy webservice : getItem method to accomplish this.

CopyService.GetItem(copySource, out myFieldInfoArray, out myByteArray);

Problem : myByteArray is always returned as NULL

Note: I have tried the same with another site that uses forms authentication but the result was the same (NULL !!)

This is my code:


Copy copy = new CopyService.Copy();

File system permission error during BACKUP service master key



I'm having a strange issue with file system permissions.

A backup database to file location e:\sqlbackup works fine.
A BACKUP SERVICE MASTER KEY or BACKUP MASTER KEY fails with the error ´MSG 15240, Level 16, State 1 Cannot Write into file ´e:\sqlbackup\file.bak' Verify that you have write permissions, etc...'

Foreach Loop Container & File System Task to copy files from target server to source server


A one-off shot at using, SSIS, I appear to be missing something. 

From what I have read here, the Foreach Loop Container in which a File System Task has been placed is how one copies files contained in a source server folder to a folder on a target server.  I have defined Source and Destination pkg variables using UNC \\servername\aharedfolder and a FileName variable that is empty.  My impression is that this is suppose to iterate through and copies all files in the source folder to the target.  I only get the first file copied.

In the FLC Collection section  I am using the Foreach File Enumerator under which I have the Folder as \\servername\sharedfolder and files as *.* .  I am not using Expressions.  The Variables Mapping reference my FileName variable.

In the FST, I both path variables set to True and reference the destination and source variables described above.  Operation is Copy File.

I appears that I need to pass a list of the source folder file names to the FileName variable, rather than some built-in logic grabbing a files in the source folder.  Is a passed filename list what I am missing?

System.Security.SecurityException: Request for the permission of type 'System.Web.AspNetHostingPerm


Good Day all,

Having an issue with an outside user accessing my IIS7 box. I do not have this problem when running the website from my host machine. I found this post: Http://forums.asp.net/t/1371394.aspx. I assure you that this is not a solution because I am not storing any of my files on a network share. 

What do you think my approach should be. 

I already have read rights to IIS user to my BIN folder. 

Thanks for the help.

Code Name WinFS: Revolutionary File Storage System Lets Users Search and Manage Files Based on Conte


One of the monumental problems organizations face today is aggregating information that's stored in disparate formats. Knowledge workers have long wanted to be able to search for content independent of format. The next version of the Windows operating system, code-named "Longhorn," boasts a new storage subsystem that makes that task easier. That subsystem, code-named "WinFS," allows the user to perform searches based on the metadata of the stored item, regardless of what type of file it is or which application created it. This article covers the basic architecture of WinFS and explains how to use the WinFS managed API.

Build an Easy Maintenance Intranet Site: Using Office Docs, File System Object, and OLE Structured S


If you've ever needed to build an easy-to-maintain intranet site, here's a solution based on Microsoft Office documents. Many sites require constant updating of their HTML, but the use of Word documents can simplify the process. This article details the construction of a human resources site that exploits the File System Object (FSO), OLE Structured Storage, and ActiveX capabilities of Word documents. This allows the HR staff to copy their revised or newly created Word files to the site, dynamically generate a list of links to their files, and free IS from the constant recoding of HR updates into new HTML pages.

Can Not load WPF project in Visual Studio 2005 on Win7 64 system, says "Project file not supported b

Dear all I am facing an issue in creating new wpf project or loading a WPF project in Visual studio 2005. I have installed Visual Studio 2005 Service pack - 1 (http://www.microsoft.com/downloads/details.aspx?familyid=bb4a75ab-e2d4-4c96-b39d-37baf6b5b1dc&displaylang=en) but still I can not see the option for wpf project  while creating a new project. Generally we can see WPF listing under item File -->New-->Project--> ".Net Framework 3.0" in VS 2005. I have few WPF project and when i try to load them it says "Project file not supported by this Installation". My System Config is given below: OS: Windows 7 (64 Bit) VS: Visual Studio 2005 with Service Pack 1 .Net Framework: 3.5 (By default inbuilt in Win7 OS)   I am suspecting something bugging related to .Net framework 3.0 in Win7. We have one option in control panel to alter .NetFramework 3.5 under "Turn Windows Features on or Off" but there I can not see something related to 3.0 :-(.   Kindly suggest how can I load my existing project and how can enable option to create new wpf Projects.   I saw few solutions suggested by people on following Thread bt most of them related to Windows XP or Vista: http://social.msdn.microsoft.com/Forums/en/vswpfdesigner/thread/06cf7bca-982c-44cf-aec9-99cf399b3000 Do someone has solution for Windows 7 (64 bit OS)

Restored copy of DB gives bizarre DENY permission to a dbo user

We took a backup of our PROD database and restored it in our Integration testing environment, and ran a script to alter the schema from the current PROD schema to the new schema we wanted to test in Integration testing. This same script has worked fine in two other environments and exhibited no issues. However, on our SQL cluster in the Integration testing environment, the script (which is hundreds of lines long and performs numerous things that require you to be dbo to do) fails on one line, a basic UPDATE statement on a single table.  The table has no deny permissions, and only has explicit grant permissions for the Application Role that accesses it.  Other users who are dbo can UPDATE the table.  I can UPDATE all other tables and do everything else a dbo should be able to do.  On every other SQL instance we have tried this on, it works. For some reason, this error only occurs specifically on this one instance of SQL, with my specific user, and this specific table.  I am baffled as to what could be going on, but need to get this repaired to bring our Integration testing environment back on line. What could be causing this?The Pragmatic TSQL Programmer

Can not copy: The file exists. (Explorer View)

Hello Community,               I used to copy bunch of files from windows explorer to sharepoint 2007 document library in its explorer view. But now I could not. It gives me error "Can not copy xyz: The file exists". The files does not exists already.             I also created many different new files [Different Name/Different File Type] and copy to server but still no luck. I have logged in to SharePoint with Admin Account and verified that no such file already exists.             I have the many machines and using Windows XP and Windows 7. For Windows 7 I never found the problem and Windows XP [with IE 6] if I use normal user for windows logon [Normal user have the “Full Control” permission in SP] I cannot use drag and drop files. It shows the error message “Cannot copy file <filename> The file exists”. For “My Network Places” I created and point to document libraries such as http://serversite/Docs [“Docs” It’s a document libraries list] but no luck. I tried from multiple Windows XP workstations and It works in few but cannot make out any differences between these machines.          &n
