How to display login failure text if user logging in user role id differ than vendors role ... i m using the following code to authenticate user role during logging in
[Code]....
I need to define some roles in my program with defined permissions. Let's say the administrator can have access only to certain features. The officer in charge to certain features and the user as well. for example, I have several group boxes and the user can access one of it only. So how i do manage these permissions? What I want do is have the roles already with the defined permissions. When I create the user and assign the role, the user should get the permission automatically.

At the moment I can only assign users to roles by using ASP.net Web Site Administration Tool.If it helps: I'm using the default login.aspx and register.aspx files from Account folder in vb web profile.

I am using ASP.NET MVC to build a site. I am using VB as programming language.I have couple of questions.
1 I have created a role "Manager". How Do I check if a user belongs to this particular role?
For now I am using If My.User.IsInRole("Manager") Then 'Direct to a view Else 'Direct to another view End If Is this the right way? 2 How to use the Authorize attribute to limit access to a Function?
I know in C# it goes [Authorize (Roles ="Manager")] but not sure in VB. Also can I define property to redirect a user who does not have "Manager" role to a particular view when trying to access this function .

View 10 RepliesIn my VS solution, I have two projects.One for the Web Interface, other for DataAcess and BusinessLogic. I know I can check if the currently logged-on user is Employee in Web Interface project like this from the code behind:
Dim isEmployee = User.IsInRole("Employee")
The problem is that I have a Class call UserManagement in my the DA and BL project which I want to check the currently logged-on user role also. I can't use Dim isEmployee = User.IsInRole("Employee") because it doesn't have aspx page.
What do I need to do to check the user role in my custom class?
I have repeater which shows a list of users and there roles. There is also a dropdown list to chnage there role see below
<td><asp:DropDownList ID="ddlChangeType" class="controlwidth100" runat="server" AutoPostBack="true" OnSelectedIndexChanged="change" /></td>
the change event works but what I need is the ID of the row so the user can be updated.
what i have is 3 text boxes
User
Role
Upgrade To
and a gridview
what i am trying to do is :when i type in the user the system will look in my table cg_security_user and recognise that the current role is "guest". Then in the Upgrade to when i type in "admin" it will update the current role(guest) to admin here is a picture is attached of what i am trying to do as it might paint a better picture the code which i have made so far is
Private Sub cmdupdate_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles cmdupdate.Click

I am using VB.NET 2008.
On this Windows 7 Professional SP1 machine, when I run the following code in the program
FileCopy(sServer & "loglog.txt", Application.StartupPath & "log.txt")
I got the error "Logon failure: unknown user name or bad password."
sServer is 1 of our server machine.
The Windows 7 machine already logged in to the sServer as administrator, and it also login to the Windows 7 machine as administrator. I run the VB program as Administrator (right click - Run as Administrator).
In the Windows 7 machine I can go to Windows explorer and copy the file manually from the sServer machine to the Application.StartupPath folder.
When my application starts, one of the first thing it does is load a list box with data from an Excel file stored on our server.To prevent an issue I had with two or moreengineers trying to load the data from the same file at the same time, I added code that copied the Excel file to a temporary file (which is,hen, deleted when the data load is done).This has been working fine up until last week. Last week our company moved to a new building.The move included servers and all. Suddenly I'm getting inundatedwith complaints from engineers about my application.It seems that they started getting the following error

I'm the only one in the company using Windows 7 which we are evaluating to decide if/when we're going to upgrade all our PC's. I am a domain administrator and my PC is in the domain and I'm authenticated. Since I installed Win 7 I haven't had any other authentication issues. The apps are built on .NET 2.0 SP2 I don't know much about our domain setup which is handled by our network administrator but I'm told that the Primary Controller is a Windows 2003 and the Secondary is Windows 2000. He tells me that by default every workstation first authenticate on the Secondary controller if it's available.

Trying to decrypt a textfile is giving me an error: The input is not a valid Base 64-string as it contains a non-Base 64 character, more then two padding characters, or a non-white space character among the padding characters.Besides that I also get an exception while debugging: A first chance exception of type 'System.FormatException' occurred in Fenix.exe When I start the app it opens the file and tries to decrypt it. After decryption the string is send to a label, so I can read it. The codes I used:
vb.net
' encrypt the file Private Function Encrypt(ByVal strText As String, ByVal strEncrKey As String) As String Dim IV() As Byte = {&H12, &H34, &H56, &H78, &H90, &HAB, &HCD, &HEF} Try Dim bykey() As Byte = System.Text.Encoding.UTF8.GetBytes(strEncrKey) Dim InputByteArray() As Byte = System.Text.Encoding.UTF8.GetBytes(strText)

View 1 RepliesI am using Process.Start(fileName) to let Windows open certain files outside of my application with their 'default application'.If "fileName" for example is a ".txt" file, it opens the file in Notepad. If it is a folder, it opens windows explorer with that folder selected.This all seems to work well, except when the user enters a file that has no application 'linked' to it.(a file that has no file associations)I have wrapped the Process. Start() in a Try/Catch block so that any errors are caught and displayed.When I now open a file without any file associations (windows does not know with which application to open it) it tells me that it cannot find any application to open it with. (The exact error is in dutch so I don't think that's going to be much help here, but I think it's clear what's happening, no?)What I would like to happen in this case is that the windows "Open With" dialog comes up, asking the user to select an application to open the file with. Now it just displays the error message and continues, making it impossible for the user to open the file unless he browses to the file manually and sets up the file association, something many users probably don't know how to do.
