File Permissions In VB2008?
Jan 15, 2009
I'm trying to put together a simple "file search" app that lets the user specify where to look, what type of files to look for, what the minimum file size is, etc. (I know...sounds kinda like capabilities that already exist in Windows!). I'm running into "access" issues, even with directories that I wouldn't think I should have any trouble accessing.I'm doing something like this:
Dim f As New FileIOPermission(PermissionState.Unrestricted)
f.AllLocalFiles = FileIOPermissionAccess.Read
Try

On an xp system using VB 2008 exprees, I'm trying to write code which will change a file's permisions when run from a non admin account. To do this I need to now how to run the code as an administrator. I've got the code to change permissions working, I just don't know how to run it with an administrator's credentials. The code is:
Imports System.IO
Imports System.Security.AccessControl
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs)

I have an application that is writing a comma separated values file. How would I go about altering the permissions of that file from .NET - for example to give read-only permissions to a particular active directory group?

My software uses a Microsoft Access .mdb file and text files for data storage. The program works great when debugging but when I install the program with Windows installer, the program gives as exception message that access is denied to read the mdb and the text files. What should I do?

I'm am developing a program for my computer and as I am using Windows 7 i have to execute it as admin every time I open my program. My IT teacher said I could set my program's permissions to 1, doing this the program would have admin privileges. But the thing is I don't know how to do it.

I'm trying to access a database (SQL Server 2008 express) using Visual Basic 2010 Express. First I got a permission error that was solved modifying the Database permissions. Now I get a new error message "This file is in use. Enter a new name .." I already have changed the Autoclose propertie to true, and also tried detaching the Database.
I'm using Windows Vista Home Premium, my string:
Data Source=.SQLEXPRESS;AttachDbFilename="C:Program FilesMicrosoft SQL ServerMSSQL10_50.MSSQL10MSSQLDATAemplo1.mdf";
Integrated Security=True;
Connect Timeout=30;
User Instance=True

I've added an FTP client to a batch publishing program that I wrote about a year ago. The batch program "publishes" CAD files from "Pro/E" to "eDrawings". Upon publishing, some of "eDrawings" files are automatically uploaded to an external server via the newly written FTP client.The publisher and FTP client are working great.I'd like to add functionality that automatically changes the permissions on the files I'm uploading to our unix server (RHEL5). When I do this via SSH, I simply utilize a chmod command (i.e. chmod 0755 file.htm).I'm using VB.Net's DirectCast in my FTP Client.Is it possible to change the permissions on the files I'm uploading via FTP once they're on the server as part of the file uploading process?

Below is the part code I currently use to write to a file,
Try
Using sWriter As New IO.StreamWriter("C:Tmp.txt", False)
sWriter.Write(m_Buffer.ToString) : sWriter.Flush()
End Using
Return True
Catch ex As IOException
End Try
But some time this results in error
Access to the path 'C:Tmp.txt' is denied
My question is, Is there a safe way of detecting File access permissions, without handling exceptions, I mean if I can some how check before opening a file for any filehandle opened for it.

Ever since I upgraded to Windows 7 Professional I've had constant build problems with VS 2008. I can't use the Hosting Process (not that I normally do) because at build I'll be notified VS could not copy a support file (the hosting exe). In addition, every time I build I'm told my previous exe is in use by another process and cannot be accessed. My only recourse is to manually delete the file. That works a few dozen times but eventually Windows stops letting me delete it and tells me that I require permission from an Administrator to make changes to the file (I'm the administrator,

I'm writing and application that creates a home folder for a given user. I can set the permissions fine, but on some of the folders I need to remove a specific group/user, "Everyone" would be an example for one of the folders. I can make it so that they are denied from all the permissions on the folder, but I can't actually get the group/user remove.

I've got two programs, one is the main and the other is the updater. So far iv'e got it so that the main program checks for an update by comparing its version number with the latest one that's stored as a text file on the server. If there's a newer one, the update program is started and the main one closed. The update program will then use a web browser component to navigate to the download link and download the new version. The only problem I'm having at the moment is, How can I get the new downloaded version to replace the current one in Program Files? and will this cause permission problems?

Just tried to create a new Data Source in VB 2010, apparently I don't have permission to connect to the 'Login.mdf' file I recently created in SQL 2008. Does anyone here have any knowledge of how to surpass this problem? I'm the Administrator of my PC and have full permissions and UAC is turned off so that shouldn't be the problem either

I've been struggling with this problem in VB.net for a while: whenever I try to access the My Documents, My video's or simular in Windows 7, I get an access denied error. The program that uses this code is a file-backup application, so it's important it can access everything. The app has admin rights, using this line:requestedExecutionLevel level="requireAdministrator" uiAccess="false" />
To confirm, I also get a nice UAC popup when starting.The app accesses the files twice. Once to calculate the file size, and once to actually copy the files. Here is the file-size calculation code (that I found online:) Function GetFolderSize(ByVal DirPath As String, ByVal includeSubFolders As Boolean) As Long

I had no trouble using it in VB6.I know there is a .NET equivalent I can use, but I need to use API on this one.I changed some data types (long to integer, integer to short) but still can't get it to work. GetOpenFileName keeps returning 0, no matter what I do.The dialog never gets displayed.
