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
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).
View 1 RepliesI 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].....

View 1 RepliesI was wondering how to implement a custom character set for use by an application, i.e. hex bytes that are read by the program then converted and displayed in the window. If this requires first converting the bytes in a file to an already implemented character set, I'm cool with it - I'll go with whatever works or works best. I'm writing with VB.NET 2010, and running Windows 7 Home Premium x64, by the way.
View 2 RepliesI'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?

With VB.net, I'm coding a simple application to get more used to the new .Net format.
I'd like to save all the information to a 'new' database file. how to create a database on the fly, once that is done i'll be able to connect to it no problem, but actually creating the file is proving difficult to work/find out.
Also, with vb.net and the newly created custom file, how can it be made to automatically open that information with the program?
Is there a method in installation to associate the file type with the new program? How can i check when the program loads if a database file has been 'double-clicked' (rather than just running from the .exe of the program) and proceed to load the data?
EDIT1 - Extra InfoThe windows application has many different fields and content etc, then i need to save that to a file that could later be loaded by 'double clicking'. I assumed the easiest way would be to create a mini-database for each unique file
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.

View 3 RepliesI am trying to restrict access to an intranet site via Windows authentication. I would like to control access via active directory user groups, but my added AD groups don't appear to be recognised by .net. I started with the following test code in my app to determine if the group could be used...
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
Me.Label1.Text = User.Identity.Name
[Code]...
The isuserinrole returns false and the group is not shown in getrolesforuser. However, getrolesforuser returns all of the built in windows groups as well as custom admin user groups created by our anti virus software (SOPHOS). This tells me that .net doesn't seem to have any issue with reading our active directory but I don't understand why my custom group is not being recognised.
I am trying to figure out how to generate code from user input. In Visual Studio 2008, Visual Basic.My script always begins with:function Init (Quest)Then from here a user would input a quest name, type and zone in a interface using windows forms.[code]I would also like to have these available on the UI but wont generate unless a user checks a box to add them or there is a box already for them but wont step into the code unless the user enters something into the box.Is there anyone that can explain how I would go about doing this. Or maybe some kind of visual studio plugin that will help me out.
View 2 RepliesHow to generate code from user input. In Visual Studio 2008, Visual Basic. My script always begins with:
Code:
function Init(Quest)
Then from here a user would input a quest name, type and zone in a interface using windows forms.
Ex:
Code:
RegisterQuest(Quest, "Kill Zombies", "Heritage", "Firestorm")
end
This part a user would enter in his interface what would an NPC say if accepted.
[Code] .....
What I need is a few text boxs that a user can input "Kill Zombies" or whatever they like and when they push a generate button it will create a file with a .quest extension. All of the code remains the same except for the quotes that would be the user input from the interface. Basically everything in quotes can be changed by the user in an interface. I have created my own functions for when a user accepts, deny and complete a quest. The user just needs to input what should happen then click a generate button to throw it all together as a .quest file to be saved in his or her quest folder for the server to call on later.
I also have many other functions like:
AddQuestRewardFaction --- (Quest, Faction ID, Amount)
AddQuestRewardCoin --- (Quest, Copper, Silver, Gold, Plat)
AddQuestStepObtainItem --- (Quest, Step ID, Description, Quantity, Percentage, TaskGroupText, Item ID(s))
Etc
I would also like to have these available on the UI but wont generate unless a user checks a box to add them or there is a box already for them but wont step into the code unless the user enters something into the box.

View 4 RepliesI have a requirement for a timer that has the following behaviour:
Millisecond accuracy I want the tick event handler to only be called once the current tick handler has completed (much like the winforms timer)I want exceptions on the main UI thread not to be swallowed up by the thread timer so this requires Invoke/Send instead of BeginInvoke/PostI've played around with CreateTimerQueueTimer and had some success but at the same time had problems with code reentrance and/or locks when deleting the timer.
I decided to create my own timer so that I could get a better idea of what is going on under the hood so that I can fix the locking and reentrance problems. My code seems to work fine leading me to believe that I may as well use it. Does it look sound? I've put in a check if the timer is deleted to make sure that the deletion is complete before the timer can be created again. Does that look ok?
Note: I should say that I call timeBeginPeriod(1) and timeEndPeriod(1) inorder to achieve the millisecond accuracy.(The following code is converted from vb.net to c#, so apologies for any missed mess-ups}
ETA: I've found a problem with it. If the timer is running at an interval of 1 millisecond, and I call, say, Change(300), it locks up @ while (this.DeleteRequest). This must be because the TimerLoop is in the this.CallbackDelegate.Invoke(null) call.

With String.Format() it is possible to format for example DateTime objects in many different ways. Every time I am looking for a desired format I need to search around on Internet. Almost always I find an example I can use. For example:
String.Format("{0:MM/dd/yyyy}", DateTime.Now); // "09/05/2012"
But I don't have any clue how it works and which classes support these 'magic' additional strings.So my questions are:How does String.Format map the additional information MM/dd/yyyy to a string result?Do all Microsoft objects support this feature?Is this documented somewhere?Is it possible to do something like this:String.Format("{0:MyCustomFormat}", new MyOwnClass())
