Now i'm working with users so for each user there are many permissions like add, update, view and delete, but i was thinking create a bit type data for each authorization, then i would load each one with 0 or 1 and show only the authorized form for the user. Could I do this? or there a better way to do the same?
View 7 RepliesMy problem is that i want to be able to set permissions for users as they log into our software. When the program loads the users get the logon screen. Then once authenticated (in SQL)they can access all of the forms. What i want to know is can i create some sort of access levels. So for example if i was to login to the software as admin then i can see the "system" menu whereas if i login as someone else they cant see the menu. Can it be done in SQL, like my authentication. Even if we added an extra column called access then if it was set to 0 you are an admin and if it is set to 1 you are standard.
View 3 RepliesI have a program that uses a font that's not stored on many computers, so the font comes with the program, in its resources. Before I was writing to a file and loading the font from that location, but I remember now that sometimes you don't have permission to write to a file. My application will not write to any other files, and having this font available is very important. So, I decided to use Marshal.AllocHGlobal() to store the font in memory, then read it back. (I'm using a PrivateFontCollection object to store these fonts.)Does Marshal.AllocHGlobal() require permissions? Is it more likely that it will throw an exception than IO.File.WriteAllBytes()?
View 1 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.
I'm working with a vb.net 2005 project that i converted from vb 6.0 last year. It's working fine in windows xp, but on vista and windows 7 i get an error saying 'Insufficient security permissions to set the system time.' Can you think of any way to replicate this error on windows xp? I'm trying to get a windows 7 box setup at work but I was wondering if there was anything I could try with xp in the meantime.

I have a vb.net (VS 2005) application which downloads files from my webserver and shows its contents to user. And I make files at my end and upload files to webserver so that the application and download & process it. This happens at fixed intervals. Now I intent to send an instant alert to users who are using that application. For example: If I type a message and send "Hello everyone" then all those people who are currently using that product should get a popup with this message. My webserver is a hosted on a unix based system. It enables me to show html content and post files & stuff online. In order to achieve my goal of sending an alert which users should get immediately what do I need to do?
View 6 RepliesIn my application, I create data and log folders that must be shared by all users using this computer. I did a lot of research, and I found a function that is supposed to grant full access to every users of a folder and its children.

2.Also , in order for the user to be able to use the application, he�ll have to register it then, everytime, before the application loads, it gets verified online that it was registered, maybe validate the registration information or a valid user name and password, no critical personal information. The target of this step is for the application to be used exclusively by the registered user and maybe on his computer only.

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 have been working on creating a small application we can run that will add permissions to a folder during an installation of a new application. The application requires read/write access to the folder and all subfolders. For whatever reason I have been instructed to include this in and install package that will be pushed out using SMS. Below is a sample of the method I use to add the user to the folder and give the appropriate rights to that user:

With Vista we are having a permission denied error when an application tries to change properties of a file in Program Data folder... before replacing with a newer version of the file.Changing of security permissions for a standard user is not an option.
