.net - Create New User In Winforms Using HDI Membership Provider?
Jan 1, 2012
I have a website with login and register forms using custom HDI Membership provider where Users can login or register new account.
Now I have a desktop software and trying to have two forms for login and register where my users can able to login or register for user convenience and not by going to the website and make them register online.So, I have these to know in order to go further.
1) Can I use HDI membership provider as I have used it in my web application?As previously I have done and I faced many problems and still didn't get clarified here
2) If No, how do I make use in order to make use the same HDI Membership.Finally I need to use the same database for my desktop software as well as my web application with all the possibilities (i.e. I need to validate each parameter of my membership class).I am able to register the user but it is not using the Membership and I'm unable to know why it is not picking up the membership provider from the app.config file.
I would like to use my custom membership provider (which is working in my asp.netapplication) in my windows forms application.I thought this would be relatively straight forward, and followed these steps:1. Copied MembershipProvider class into my application.2. Add reference to System.Web3. Create app.config with membership settings i.e:
Over the past few weeks I've been attempting to convert the readily available C# code for the Membership Provider etc whilst working with MS Access. I'm fairly experienced with VB unlike C# and have ran AccessMembershipProvider.cs, AccessConnectionHelper.cs and so on through 3 different converters. All of which have given a varying degree of errors, all of which I've fixed, either by ever so slightly re-writing the logic or in the Cryptographic case finding a working translation.
This evening I have fixed all of the errors from all of the now converted VB files (which I was pretty pleased about as you can imagine), I then created a simple login page to test this out, added a new user to the system and tried to login to find out I'm being told the username or password is wrong.Just to clarify, the converters all had an error or two or even more in some cases which I've bypassed but now I can't login - at all!!Finally I've written reams of code over the years and am really stumped on this one, has knowone actually successfully converted these files from C# to VB and actually got it working?? I'm not looking for someone to send me there hard work but I am almost at the point of not wanting to bother with it anymore and I just can't believe that it's not out there to download.
net and the .net membership provider.i want to bring back a gridview with user account information, like GetAllUsers() does. However i want to only bring back users with certain profile information, that will be users whos profile information matches the selected value in a dropdownlist on the same page. I am using profile provider to record just one extra piece of user information.Can i change or override the GetAllUsers method for this? Adding an extra parameter so its GetAllUsers by Profile. Membership has a FindUsersByName method, i want to do something similar with users by Profile.
The logged-in 'UserId' and 'UserName' is getting displayed correctly, but now how do I use the string 'lmember' in my 'SELECT' statement when I need to display the related information from the table 'aspnet_Users' for the logged-in user? getting the following select statement:
SelectCommand="SELECT * FROM aspnet_Users WHERE (UserName= ????)"
I am using asp.net membership and trying to update a users details but get the following error: Error 2 Overload resolution failed because no accessible 'New' accepts this number of arguments.
Below is the full .vb code: Partial Class FamilyAdmin_edit_user Inherits System.Web.UI.Page Private username As String Dim user As MembershipUser Private Sub Page_Load() [Code] .....
Before I had: Dim user As MembershipUser
And got the error: Object reference not set to an instance of an object. Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.
Exception Details: System.NullReferenceException: Object reference not set to an instance of an object.

Using the Asp.net Membership & Profile Providers: Am I able to retrieve a user profile using their Membership UserID instead of their Username?The reason I ask is because if I have the UserID and not the Username I would have to write the following two lines of code [code]Dim Profile As Profile = Profile.GetProfile("UserID")Will this affect performance? Is my design bad? Am I missing something? I am aware that I can retrieve the current logged in user using the following code: HttpContext.Current.User.Identity.Name
Is it possible for a VB.NET web application to check the user's Windows security group and behave differently accordingly?I'd like to disable a certain bit of functionality if the user does not belong to a specific windows group.I've tried using the Microsoft code at url... but get the error "Reference to a non-shared member requires an object reference" on the "irc = WindowsIdentity.Groups" line (I have imported all the required namespaces).Does anyone know if it's possible to get the user's security group?
In 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 want to pass an asp.net membership user name to a subroutine and retrieve the profile property named FullName for that user, how can i achive this in vb.net?
i have 2 computers - a Server and a Client pc which is running on local area network with MICROSOFT SQL SERVER 2008 R2 Developer kit at the main pc and Client computer will need to connect to SQL SERVER at main pc using connection string.Let me named server computer as 'MAGNA-PC' and the client pc as 'LAC-PC' and database name is 'db_referafriend' so the code for MAGNA-PC(server) connection string is:[code] i GOOGLE and YOUTUBE for almost 2 weeks before i post . I know that i need to configure the sql configuration manager and enable tcp/ip also add a new port at firewall to allow remote connection also add the sqlserver.exe and sqlbrowser in firewall and I have also chosen "Using both TCP/IP and named pipes" under Remote Connections in the SQL Server 2005 Surface Area Configuration. and all of this doesnt work!
I have used VB (versions 2 - 6) through many years; however, I am crash-course training myself into the VB2008 / VB2010 world kicking a screaming. I would like suggestions as to what SQL database access method should I focus more on in my learning process without making me feel that I'm a million years behind. I know I have WinForms where I can create a datasourse and drag / drop fields or tables on a form to create a grid (not really what I'm looking for).
My trouble isn't so much designing the form but in how I access the database. Theres XML, LINQ to SQL, ADO.NET, and many other methods. Not only do I need to grasp these methods quickly but I also need to know what type of projects I should create. What I mean is...I was thinking that I would design a WinForm app; however, I see that there are WPF apps and others to chose from. This is getting deep. I know it depends on the project that I'm working on. My plans are to write an app based off of either an SQL Express 2008 or SQL Server 2008 database. This first app will be standalone for now but may later become multi-user. I know I'm far behind on my learning curve coming from VB6. I have read a bit on VB2005 / 2008 / 2010. I own both VB2008 and VB2010. I use VB2008 at work. I know ADO.NET is still alive but by what I read online, it's a dying method and is only kept for backward compatibility. XML and LINQ to SQL and other methods are all pretty new to me.
I have a .Net 2.0 Windows Forms application which needs to be run as a specific user (right click, run as).I need to be able to check which user has launched it and stop if it is not the specific user.All the examples I have found show the logged in user.How can I access the application executing username?
Does anyone know of a good way to have a user enter an amount of time (hours and minutes) using winforms controls? At the moment I have two numeric up downs, one for time and one for minutes that I then parse to create a timespan. The only other idea I have is a text box that a user can enter a "00:00" time in, and validate the input. Both of these ways seem a bit bad (in UI terms) though.
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].....
What I hope is relevant code below, I would like the User to be able to Right click when hovering over the PictureBox container of a User Control and pop up a menu which allows a User to check or uncheck an item in the context menu. How can I acheive that?
A while back, I wrote my own settings provider because I was having problems persisting settings in a class library. (Note - I had no problems persisting settings from an application).Today, I just did a test of persisting class library settings and it worked, without my custom provider.The test is:
(1) Create a class library
(2) Add a setting - 'Name'
(3) Add a class with a public shared property 'Name' that reads and writes to the setting 'Name'.
(4) Create an application that references the class library, and use the shared property to read and write the 'Name' setting.
I'm sure that before the 'Name' setting would persist while the application was open but after I closed it and re-opened it, the setting would revert to the default.This is not happening now and I'd like to be sure that I was being an idiot before and not an idiot now.
ETA: I've noticed that the first time I create a test app, change the setting, close, and reopen, the setting is not persisted. Subsequently it is. May be I gave up after one try before. Any ideas why it's not persisted the first time?
ETA2: As an example, I have a class library called 'MyLibrary' and a test application called 'MyApp'. I do the steps 1-4 above, and below are the contents of the user.config file found at C:Documents and SettingsUser NameLocal SettingsApplication DataMyAppMyApp.vshost.exe_Url_vi5gjcooahbdm2ma3dcay0mkexu2suul1.0.0.0. Note: I did not touch the settings in MyApp;-
I'm trying to create a button that will hide the panel that I have docked at the centre of my user control. [code]This works to an extent. However, when the bottomPanel is set to Fill it seems to fill the entire control, and not just up to toolStrip1. Can anyone tell me why this is happening, and how to correct it?
I want to create autohide Side bar in Winforms using VB.Net 2005. I have main form there is already fixed side bar with lot of options now just I want it autohide just like VS.NET 2005 Toolbox?
Can I use tools commonly for all the winforms? How to create common toolstrip? For example : I have one toolstrip.it has one delete button. All winform has one datagrid and data comes from differs tables. Now I want to remove the data from the any datagrid all winforms.
I want to make typewriter effect like: [URL] dim s as string = "123" label1.text = s.substring(0,1) WAIT label1.text = s.substring(0,2) WAIT label1.text = s.substring(0,3)
The idea is that I would have a set of forms, users would click through a "forward" and "back" button, and the current form would change to a different one. My issue is that I can write code that just pops up a new form, but im not sure how to do a "replacement" of my current form. How is this usually done?
I'm trying to bind a WinForms TreeView control to some user-defined objects. In particular, I'd like to bind aTreeNode.Text property to myObject.Name. My strategy is to create xTreeNode, a subclass of TreeNode, add a DataBindings collection, and expose its Text property. This would allow me to write some code like this:
Dim oBinding as Binding Dim bs as New BindingSource bs.DataSource = myObj
I'm trying to write an application that will allow a non-administrator user to create virtual directories in IIS6. I've tried numerous different ways of impersonating a administrative account but nothing seems to work to create the virtual directory.
Here's some of what I've tried: dim sDirPath as string = "IIS://remotehost/W3svc/1/root" Dim de As DirectoryEntry = New DirectoryEntry() de.Path = sDirPath de.AuthenticationType = AuthenticationTypes.Secure de.Username = tbxUsername.Text [Code] .....
what is the correct way to impersonate another user in winforms application that will allow me to create the virtual directory without the user that's running the application being an administrator on the web server? I know this can be done, IIS manager allows you to use "connect as" checkbox to do it.
