Site Level Folder Read/write/delete Permissions From Webpage?
Dec 20, 2011
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 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 bet someone already asked this but i cant seem to find it. Ok i need is a global settings that can be updated which will affect all users. I was using xml files in the program filestill now and I need to get around using this because the files can be delete or over written incorrectly. I started using the settings option and realized application level is read only and i cannot use user scope because then it wont be global settings. Is there an alternative to this.

I'm stuck at the login, its a .php page with 2 text boxes, 1 check box and 1 button.Is there any way to manipulate those objects by using controls in my form?

I've looked for code on this, and it seems needlessly confusing to me. I've tried some code I found and it doesn't return the proper value (I can't find the link to it now). So, I'm attempting to avoid that which I do not understand by writing a function that creates then deletes a file:
Friend Function GetFolderAccess(ByVal sDirectory As String) As Boolean
Try
Dim fs As New FileStream(sDirectory & " estfile.test", FileMode.OpenOrCreate, FileAccess.ReadWrite)
Dim s As New StreamWriter(fs)
[code]....
Through testing, this appears to work for both read and write access. I originally had a File.Exists before the File.Delete, but the function would sometimes return True when it should have returned False.

All i am trying to do is read and write files to a shared folder on a network in visual basic (VS 2010). I can go to the folder through windows without a problem and without being prompted for a password. However when i try to do it through visual basic, it cant find the directory. Here is my small snippet of code that i (hope) is telling me that the program cannot connect to the folder. [code] Are there any known issues with VS 2010 that may cause this? Maybe something else in my code that could have an effect? This is in my form_load event though, so it is literally one of the first things that runs.

Im trying to write a loop that will read through a number of *.csv files in a folder and then stuff the data into SQL. The code works and will happily put the data i want for a named file into SQL no problems. So when i had that working i then tried to loop it so that it would do the same for all files in the folder until all files had been done, and not error out if there where no files etc.
Maybe im tired (well, i am) or not had enough coffee but i just cant get this to work, it should be simple - i know it is infact, but its making ME feel simple.i think i should have an integer count in there, but similar examples ive seen dont use one. Also when trying to open the path i get an error at runtime "the path is not of a legal form"
code:
Public Sub ImportCUSTCSVs()
Dim dt As New DataTable()
Dim line As String = Nothing[code].

The gist of the program is to:
- Read a CSV file into an array
- Get this visible in a list box, so the values can be:
- Sorted
- Edited
- Deleted
- Added
- Finally save these manipulated values back to the text file
Would love some suggestions and code as to how to get this going, hopefully I'll get the hang of it and come back and fourth for help

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).

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,

If 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.

If 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?

I have a user of one of my programs reporting that they get an "access to the path...is denied" error during this section of [code]He's using Windows 7 x64 with UAC turned on. The location of "FilePath" is a subdirectory inside Program Files (x86) in this case.I tried to reproduce the error on my Windows 7 x64 system by enabling UAC (I usually have it off) but the program worked fine. However, in my case, "FilePath" is not in a protected system folder like Program Files (where write permissions are not given to normal users without admin elevation).So I tried to recreate this situation on one of my Vista x86 Virtual PCs where the "FilePath" would be inside Program Files. However, my program again worked fine. It had no problems writing to the Program Files folder with a normal user account, UAC turned on and no elevated permissions required.
Thus, I am confused. Why does it work for me and not for him? I want to try an x64 virtual machine but I can't with the software I have (Virtual PC doesn't support x64 guest OSs, VirtualBox won't run the software that my program interacts with). So maybe you guys can help me instead. Are the write permissions for the Program Files (x86) folder different between x86 and x64, or maybe even Vista and 7?

I 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.

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

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.
