I am creating a website using asp.net mvc model. When you create an mvc application asp.net automatically creates roles/profiles for user and admins (as far as i know) and corresponding tables in sql server database.I a need a new profile/role names "sponsor" that has all the benefits of users/admins (like authorization etc).

I have a winforms (VB 2008) based app that I'm developing and I want to use custom roles for user access.Application Layout:I have a Main form that opens a login form when certain actions occur.The Login form intern uses an authentication class that I've created, to authenticate users and set access rights.On my Applications settings page, I have Authentication Mode set to Application-defined because I cannot use Windows Authentication in the environment where this will be deployed.
The application uses a MS SQL 2005 db and the 3 tables I'm using in the authentication process are the User_Account , User_Roles and User_Access tables. The combination of an account in the User_Account and the roles within the User_Roles table are the bases for the User_Access table. Using the User_Access table is how I assign access to the various functions within the application
Authentication Method:To authenticate a user, I'm using the "My.User.CurrentPrincipal" (Code below) method. The My.User object works great and allows the use of "My.User.Name" property throughout the app when referring to the currently authenticated user.
Access Method:In order to set the current users access levels I'm using a function within my Authentication class and passing in My.User.Name as a variable. The function uses a Dataset Table Adaptor and a Select Case statement inside a For loop to assign all the access levels for the user (Function code below).
My Problem:This method of assigning access rights to a user does work but it's not persistent throughout the application as the My.User object is.I would like to find a way to create custom roles through the My.User object using its .IsInRole property. I would like to have these roles dynamically created using my User_Roles table.This would allow the custom roles to be used throughout my application using the My.User.IsInRole ("MyRole")syntax ...similar to how I'm currently able to use My.User.Name.Unfortunately the only roles I can currently validate against are the built in Windows
type accounts (Adminisrator ...ect.).
'User Authentication example:
If Authenticate.CheckPassword(tbxUserName.Text, strPassword) Then
My.User.CurrentPrincipal = New GenericPrincipal(New GenericIdentity(tbxUserName.Text), Nothing)[code].....
I am looking for ways to implement custom user-roles in windows application with vb.net. I got a database table called Roles with Administrator and User entries. User cannot see some of the form data. In ASP.NET MVC we can do like.
[Authorize(Roles = "Administrator")]
public function GetAccount() as Array
End Function
We have an application that's installed at several locations but we are having an issue at one particular site. In short the application settings (My.) are not being saved after a reboot. The application is build in VB.Net v3.5 Framework and we are not experiencing any issues elsewhere.
This particular site is using roaming profiles and the network administrator ensures us that the correct permissions are applied to the user account(s) and all application data is being saved to the server. I've asked the network admin to check for the existence of the user settings file user.config in the Application Data directory and he says it doesn't exist.
In our application we store the connection string to the database in the application settings under the user scope. If no connection string is present or if one is present and a connection to the database cannot be made then a form is shown asking the user for the database credentials. Each morning when the users boot the machine and opens the application for the first time they are asked for these credentials but if they close the application and restart it they are not asked for them. This indicates to us that the settings are being saved but once the pc is rebooted and the application is opened for the first time they are asked for the database credentials. This seems like the settings are not persisting after a reboot.
I have vbscript code that enumerates user profiles from this registry path:
HKLMSOFTWAREMicrosoftWindows NTCurrentVersionProfileList.
How can this be done using Visual Basic 2010? Is there a class or method that I would use to accomplish the same thing or would I have to read the registry path into an array as you do with vbscript? My application will be ran on the local computer just so you know this information is not being gathered from across the network. I have been looking for awhile and haven't found anything that will work so far.Once I have the user profiles from the computer, I will populate this list into a drop-down combo box.
I'm developing a "small" warehouse-management WebApplication for few users(5-10 parralel) but with a complex authorization system(checking if pages,menus,TabPanels, UserControls and even single controls are visible or enabled) and permanent and frequent access. Because i've only limited experiences with the ASP.Net MembershipProvider, i'm unsure what's the best approach for following goal:
I want to hold all users, roles and frequently used masterdata in the Cache(in a Dataset). Hence every readonly access should be faster and causes less traffic than always using the database. On updates,deletes and inserts i would update the cached dataset and also the database.
Can i use or extend the SqlMembershipProvider to achieve this goal and if possible how?
Is there a method for checking which roles a user has in SQL using SMO? I can add a role via: user.AddToRole("Administrators") But cannot see an obvious method to progmatically list them.

I have some custom user controls in my .net winforms program that do not display correctly when the user has selected larger text size. This setting:
My controls look like this:
Instead of like this:
The bill to area and ship to area are both custom controls. I don't know if this is contributing to the problem but I do have code in each to scale the phone/fax areas to stretch nicely, like this code from the bill to control,
Private Sub panFaxPhone_Resize(sender As Object, e As System.EventArgs) Handles panFaxPhone.Resize
panFax.Width = (panFaxPhone.Width / 2) - 1
panPhone.Width = (panFaxPhone.Width / 2) - 1
panFax.Left = panFaxPhone.Width - panFax.Width
End Sub
How can I get my controls to size correctly while still respecting the users choice for larger text (I don't want to just set the AutoScaleMode to None)? After playing with this for a long time it seems to be a problem with anchors in the child controls. See this below image, the inner black box is the control with its border turned on, the text boxes (like name) are anchored left and right and should stretch to fill the control, but don't.
I am attempting to create a basic program and I need to know how to incorporate INI files for profiles in order to quickly pull up data from one person to the next.
Public Class IniFile
' API functions
Private Declare Ansi Function GetPrivateProfileString _
Lib "kernel32.dll" Alias "GetPrivateProfileStringA" _
[code]....
And placed it into a module, which I then wen't to my main program and attempted to place this:
Dim ini As New IniFile(Profiles.ini)
Dim value As String = ini.GetString("Names", "1", "Default Value")
To attempt to retrieve the data, but I get no error or information from it. The ini file is inside the folder of the project and I set the SectionName and KeyValue to the corresponding names. I think I am having trouble with syntax? Not 100% sure. This is the code that I got from the same source as the module for using the module.
Dim ini As New IniFile(FileName)
Dim value As String = ini.GetString("SectionName", "KeyName", "Default Value")
And I adjusted to what I believed would be the proper format.
I have an issue to do with roles in mvc 3 vb.net app..Say I have Admin, Developer, PowerAdmin roles.. if I want to restrict view options based on roles I have been using a if statement in the view to hide the link all together such as:[code]I am also decorating controller actions with authorize in places. The Problem is this say I have several actions that should only be available to say a user who is in all three roles or even 2 of the roles in any combination.. Would I simply nest the if statements in the view to hide those view items? What about controller functions.. Is it possible to decorate controller functions with something like [code]and then have that function only accessible by someone with both roles????

Is this even allowed in the web.config? I have 3 websites. One for Dev, UAT and PROD. Now for each sites I have different user groups for each set up. I just want to find a way that I can just find what URL i'm at and point it at the certain user group. I'm guessing I have to make a web.config for each because you can't do conditional statements but I'm just making sure. If I have to make a web.config for each how can I go about setting that up?

I am wanting to update our current windows forms security to something a lot more flexible. At the moment we have a single column in thew users table which is named 'Access_Level', this field holds an int value (1 to 4) which is then use to determine users access to certain areas of the application. This worked fine when the system was small, but the system is growing rapidly now so I think it is a good time to update the user access and possibly introduce roles.

I've got a page (aspx) that contains a usercontrol (ascx).On postback of the aspx, I'd like to read some control values in the ascx. So upon reading some good articles, I created an event in my aspx that fires on postback.The event handler is in the ascx, and simply writes the values I'm interested in to the viewstate so that the parent page can read them.The problem is my event handler never gets hit, even though I see the event is raised as I step through the code. So my code bombs when trying to read the viewstate (which is empty)[code]Oh, did I happen to mention I'm dynamically loading the ascx? :)

I'm trying to host some static files for access by an ASP.Net web role and a separate data worker role that are both running on the same deployment (they use a global static interface).
However, I'm unsure how exactly to 'host' them, I've tried using virtual folders via HttpRuntime.AppDomainAppPath, but it only occasionally works in debug mode. The files also don't seem to get packaged into the deployment packages made by VS vis CSPack (though this might be a separate issue, is it possible to fix this too?)
The static files in question are actually WordNet, which I'm using through WordNet.Net, If that makes any difference. I also need the solution to work in both the cloud deployment and the emulator (if possible).

View 1 RepliesI'm trying to build a dial control as a custom user control in VB.NET. I'm using VS2008.so far I have managed to rotate image using graphics.rotatetransform . however, this rotate everything. Now I have a Bitmap for the dial which should stay stable and another Bitmap for the needle which I need to rotate.so far i've tried this:
Dim gL As Graphics = Graphics.FromImage(bmpLongNeedle)
gL.TranslateTransform(bmpLongNeedle.Width / 2, bmpLongNeedle.Height * 0.74)
gL.RotateTransform(angleLongNeedle)[code].....
As I understand it, the image of the needle should be rotated at angle "angleLongNeedle" although i'm placing the rotated image at 0,0. However, the result is that the Needle doesn't get drawn on the control.
