I would like to read the NT Security (Read, Write, List, Inherited, blah blah blah) permissions from a file. I already have some code, and can get the names and SIDs, but cant seem to figure out the actual access bits.

I have a link on a VB.net aspx page that needs to open a folder in a subdirectory of a web site and provide read and write permissions so that files can be copied into and read from as well as deleted. ONLY from this folder.I have this funtionality working on a dev and demo PC but they are both on my domain. Clicking the link opens Windows Explorer and I can copy /cut & Paste, etc.The public/production PC is on the LAN, but not part of the domain. I know there are ways to allow folder read/write permissions on a public server like this but I am not too sure on the safest way to do this. The upside, the only users that need to have read/write/delete access are employees. Forms Authentication, ASP Membership directs non-employees to other pages within the site. Likewise, the membership directs employees to an admin section of the site.

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 created a Project, now i wanna publish it. I should copy a folder from the CD on C:ProgramsTest .... Now my problem, how can i put the permission on it:
For all Folders and Subfolders should be: Group: User Permission:
Change -- true
Read -- true
Write -- true
I have a small application that creates users in the AD. It adds the users fine, and creates them a home directory. My problem is with granting the user permission to the home directory and is two foldFirstly the code detailed below adds the user to the folder, but because the account is newly created it displays as the SID rather than the name, not such a big deal, but sometimes the code fails as the replication has not caught up and the user isnt found. I beleive the answer here is to use the SID rather than the users name to add permissions, however I am not sure how to retrieve and store this when the account is created using directory services. Secondly and more frustrating is that once the user is added to the folder ACL their permissions are all blank.
Try
Dim Dinfo As New DirectoryInfo(Directory)
Dim DS As DirectorySecurity = New DirectorySecurity()
Dim Rights As FileSystemRightsFileSystemRights = FileSystemRights.Modify

I found how to create a share in C# using the ManagementClass to create an object to reference the Win32_Share class and the ManagementBaseObject class to access the members of the Win32_Share class.My problem is that I want the "Everyone" permissions to default to Read only.When I set the share via Windows Explorer it works fine but the code in my C# application is allowing Full Control and Change permissions along with Read permission.I tried using the DirectorySecurity class but that blows away the Security permissions (under the Security tab)without affecting any Share permissions of the Everyone group (under the Share tab).I don't want to change the Security permissions, I want to change only the Share permission (you know, the permissions that appear when you hit the Permissions button on the Share tab).
View 4 RepliesIf I don't grant write permissions to the folder containing my exe file, I get an 'Access to the path binReleaseprogram.exe' is denied. But if I grant it write permission I don't get the error. Why would the executable need write permissions? I'm not writing anything to the root where it resides.
View 1 RepliesIf I adjust permissions using the Security.Accesscontrol.DirectorySecurity on a directory, how can I make it so that subfolders automatically inherit the new permissions?
Brief overview of the situation is that my neighbors can't connect their Vista laptop to a shared folder on their computer running XP Home. They're getting access errors which I believe is because of the rights set on the folder. The problem is that XP Home won't let you adjust that and they're not upgrading.
I'm able to add the Everyone user to the directory I specify. But if I drag a new folder in or create a new folder, it does not have the Everyone user. Is there something I'm missing in this class that will let subfolders and files inherit the permissions?

View 4 RepliesI have an app written on an xp pc which I want users to run on Vista
The app needs to delete a file on a portable drive in a particular folder
This folder was created on the xp machine and copied to the portable drive
The app will not delete a file in this folder on Vista but it will on xp
When I check folder security on vista (which does not exist on xp) I find that the folder does not have full control assigned
my app will write a file to that folder & delete it but will not delete a file put there from the xp pc
If I change the security in vista to full control it works
what I want to do is see if the folder has full control when the user selects it and advise them they need to alter security as I can not do it in the program
basically I want to advise them the moment they select the folder, not when it fails to delete the file after entering misc details in the app which are reuired before the file is deleted.
here is the poblem after installing the program only users can only use the program if they are logged as admin can use the progam. like writing to the database. i either need to find out how to change the users
to have write access during install or great a dll and add it to the install and as the program starts it checks the file and folder access of the users. if the access does not have write enabled then it runs the dll to fix it. not having any code posted i really do not have any idea how to do this. oh yes the short verision is if the program is install as an administritor only a user that have administritor access can write to the database.
I use the following code in order to check if certin user exists in the DACL:
Dim l_managemantObject As ManagementBaseObject() = CType(securityDescriptor.Properties("DACL").Value, ManagementBaseObject())
For Each mObject As ManagementBaseObject In l_managemantObject
l_name = CType(mObject.GetPropertyValue("Trustee"), ManagementBaseObject).Properties("Name").Value.ToString
If CType(mObject.GetPropertyValue("Trustee"), ManagementBaseObject).Properties("Domain").Value IsNot Nothing Then

View 4 RepliesI'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?
