  • Back up and restore Active Directory password per user

    - by Robert Perlberg
    For administrative purposes, I sometimes need to log in as another user to diagnose a problem with their account. I'd like to be able to do this without having to change their password so I don't have to keep bothering them. Under Unix, I can just save the encrypted password from the passwd file, change the password, then edit the old encrypted password back into the passwd file. Is there a way of doing something similar in AD?

  • Usability: Save changes using "Apply" button or after every single change?

    - by mr.b
    I am interested in hearing opinions and experiences of fellow developers on topic of designing user interface, usability AND maintainability-wise. Common approach is to allow users to tweak options and after form gets "dirty", enable "Apply" button, and user has possibility to back out by pressing cancel. This is most common approach on Windows platform (I believe MS usability guidelines say to do so as well). Another way is to apply changes after every single change has been made to options. Example, user checks some checkbox, and change is applied. User changes value of some text box, and change is applied after box looses focus, etc. You get the point. This approach is most common on Mac OSX. Regardless of my personal opinion (which is that Apple is better at usability, but software I usually write targets Windows users), what do you people think?

  • Sendmail yields "user unkown" errors even after (wrongly) setting up a catch-all account

    - by user59240
    I was trying to follow the instructions found here to set up a catch-all account, but still I get the following message for mails sent to non-existent users: The error that the other server returned was: 550 550 5.1.1 [email protected]... User unknown (state 14). Everything else works, though... /etc/mail/local-host-names and /etc/mail/virtusertable were set up as instructed. Any advice? Thanks!

  • current_user.user_type_id = @employer ID

    - by sscirrus
    I am building a system with a User model (authenticated using AuthLogic) and three user types in three models: one of these models is Employer. Each of these three models has_many :users, :as = :authenticable. I start by having a new visitor to the site create their own 'User' record with username, password, which user type they are, etc. Upon creation, the user is sent to the 'new' action for one of the three models. So, if they tell us they are an employer, we redirect_to :controller = "employers, :action = "new". Question: When the employer has submitted, I want to set the current_user.user_type_id equal to the employer ID. This should be simple... but it's not working. # Employers Controller / new def new @employer = Employer.new 1.times {@employer.addresses.build} render :layout => 'forms' end # Employers Controller / create def create @employer = Employer.new(params[:employer]) if @employer.save if current_user.blank? redirect_to :controller => "users", :action => "new" else current_user.user_type_id = @employer.id current_user.user_type = "Employer" redirect_to :action => "home", :id => current_user.user_type_id end else render :action => "new" end end ------UPDATE------ Hi guys. In response: I am using this table structure because each of my three user type models have lots of different fields and each has different relationships to the other models, which is why I've avoided STI. By 1.times (@employer.addresses.build) I'm connecting the employer model to the address polymorphic table in one form, so I'm asking the controller to build a new address to go along with the new employer. Averell: you mentioned encapsulating... something in the model using a 'setter' method. I have no idea what you mean by this - could you please explain how this works (or direct me to an example elsewhere)? With tsdbrown's answer I have managed to create the behavior I want... if there's a more elegant way to accomplish the same thing I'd love to learn how. Thanks very much. Thanks to tsdbrown for answering the current_user.save problem!

  • NEED your opinion on .net Profile class VS session vars

    - by Ted
    To save trips to sql db in my older apps, I store *dozens of data points about the current user in an array and then store the array in a session. For example, info that might be used repeatedly during user’s session might be stored… Dim a(7) as string a(0) = “FirstName” a(1) = “LastName” a(2) = “Address” a(3) = “Address2” a(4) = “City” a(5) = “State” a(6) = “Zip” session.add(“s_a”, a) *Some apps have an array 100 in size. That is something I learned in my asp classic days. Referencing the correct index can be laborsome and I find it difficult to go back and add another data point in the array grouped with like data. For example, suppose I need to add Middle Initial to the array as a design alteration. Unless I redo the whole index mapping, I have to stick Middle Initial in the next open slot, which might be in the 50s. NOW, I am considering doing something easier to reference each time (eliminating the need to know the index of the value wanted). So I am looking to do this… session.add(“Firstname”, “FirstName”) session.add(“Lastname”, “LastName”) session.add(“Address”, “Address”) etc. BUT, before I do this, I would like some guidance. I am afraid this might be less efficient, even though easier to use. I don’t know if a new session object is created for each data point or if there is only one session object, and I am adding a name/value pair to that object? If I am adding a name/value pair to a single object, that seems like a good idea. Does anyone know? Or is there a more preferred way? Built-in Profile class? Re: Profile class I have an internal debate about scope. It seems that the .net Profile class is good for storing app-SPECIFIC user settings (i.e. style theme, object display properties, user role, etc.) The examples I give are information whose values are selected/edited by the user to customize the application experience. This information is not typically stored/edited elsewhere in the app db. But when you have data that 1) is stored already in the app db and 2) can be altered by other users (in this case: company reps may update client's status, address, etc.), then the persistence of the Profile data may be an issue. In this case, the Profile would need to be reset at the beginning and dropped like a session.abandon at the end of each user's session to prevent reloading info that had since been edited by someone. I believe this is possible, but not sure Currently, I use the session array to store both scopes, app-specific and user-specific data. If my session plan is good, I think I will create a class to set/get values from the session also. I appreciate your thoughts. I would like to know how others have handled this type of situation. Thanks.

  • terminal server 2003, changed location of user profile "Desktop" items

    - by Bamse
    have a terminal server 2003 that about 50users can use, users are saving documents on the desktop, today users complain that documents on the desktop is missing, no upgrades or changes has been done the error is that the server reverted to load items the folder name "Desktop" instaed of using the local language "Skrivbord" (swedish for desktop) So the files are still on the server located under the users swedish folder name, but server does not load it, server however does load files located under the English folder name how can the terminal server from one day to another just change from where it loads the user profile desktop files?

  • I have three different websites and I want to create a single entry point for all of them but how?

    - by austin powers
    Hi all, We are creating three different websites using asp.net but for the user part we want to implement an approach so that each user only need to create an account in any of these three sites but use the same account in other websites too. here is what I've suggested : create a useracount.website.com server then put the sql server there and implement core user account library there such as (creating/editing/etc...) whenever a visitor needs to have an account or needs to login into out sites then we will redirect him to the useracount.website.com address and he/she should login from that point. and for the maintaining the user's states I've suggested to using cookies. and all of these scenarios should be implemented by asp.net and sql. please let me know with best approach cause I feel mine is not that good specially the cookie part. cheers.

  • Is an editable select box the right way?

    - by Neil Middleton
    I have a scenario where a user is emailing another user in an HTML based web app. For the To: field, the user may select one of a pre-defined list of emails OR enter their own ignoring the pre-defined options. What would be the best way of doing this from a UI point of view? I've looked at editable select boxes using jQuery but none seem to let you enter your own option. Is there some other UI mechanism that would work here?

  • How to change default user (ubuntu) via CloudInit on AWS

    - by Gui Ambros
    I'm using CloudInit to automate the startup of my instances on AWS. I followed the (scarce) documentation available at http://bazaar.launchpad.net/~cloud-init-dev/cloud-init/trunk/annotate/head%3A/doc/examples/cloud-config.txt and examples on /usr/share/doc/cloud-init, but still haven't figured out how to change the default username (ubuntu, id:1000). I know I can create a script to manually delete the default ubuntu and add my user, but seems counter intuitive given that CloudInit exist exactly to automate the initial setup. Any ideas?

  • How to force a login for an administrator when using Remote Desktop Connection and fast user switching enabled?

    - by brett rogers
    Scenario: I am at work. I want to remote desktop into my machine at home. Problem is, my 5-year-old daughter is playing games on Starfall.com (or something similar) on her (non-admin) account. When I attempt to connect I see this message: Another user is currently logged on to this computer. If you continue, this user has to disconnect from this computer. Do you want to continue? I click Yes and then see Please wait for 'UserName' to respond This presents my daughter with an Allow/Disallow dialog on whether to let me connect. She clicks Disallow (or No or whatever it says) and then I see 'UserName' has denied your request Question: How can I force my account to log in and disconnect her session? Additional Info: My account is an administrator account. My daughter's account is a non-administrator account. Home machine is Windows 7 Pro with fast user switching enabled. Turning off fast user switching is not an option (Kyle pointed out in his answer that turning it off would allow the admin to force another user off). I would keep fast user switching's ability to change accounts without closing the previous account's session over being able to force myself to connect.

  • Why is OpenSSH not using the user specified in ssh_config?

    - by Jordan Evens
    I'm using OpenSSH from a Windows machine to connect to a Linux Mint 9 box. My Windows user name doesn't match the ssh target's user name, so I'm trying to specify the user to use for login using ssh_config. I know OpenSSH can see the ssh_config file since I'm specifying the identify file in it. The section specific to the host in ssh_config is: Host hostname HostName hostname IdentityFile ~/.ssh/id_dsa User username Compression yes If I do ssh username@hostname it works. Trying using ssh_config only gives: F:\>ssh -v hostname OpenSSH_5.6p1, OpenSSL 0.9.8o 01 Jun 2010 debug1: Connecting to hostname [XX.XX.XX.XX] port 22. debug1: Connection established. debug1: permanently_set_uid: 0/0 debug1: identity file /cygdrive/f/progs/OpenSSH/home/.ssh/id_rsa type -1 debug1: identity file /cygdrive/f/progs/OpenSSH/home/.ssh/id_rsa-cert type -1 debug1: identity file /cygdrive/f/progs/OpenSSH/home/.ssh/id_dsa type 2 debug1: identity file /cygdrive/f/progs/OpenSSH/home/.ssh/id_dsa-cert type -1 debug1: Remote protocol version 2.0, remote software version OpenSSH_5.3p1 Debia n-3ubuntu5 debug1: match: OpenSSH_5.3p1 Debian-3ubuntu5 pat OpenSSH* debug1: Enabling compatibility mode for protocol 2.0 debug1: Local version string SSH-2.0-OpenSSH_5.6 debug1: SSH2_MSG_KEXINIT sent debug1: SSH2_MSG_KEXINIT received debug1: kex: server->client aes128-ctr hmac-md5 none debug1: kex: client->server aes128-ctr hmac-md5 none debug1: SSH2_MSG_KEX_DH_GEX_REQUEST(1024<1024<8192) sent debug1: expecting SSH2_MSG_KEX_DH_GEX_GROUP debug1: SSH2_MSG_KEX_DH_GEX_INIT sent debug1: expecting SSH2_MSG_KEX_DH_GEX_REPLY debug1: Host 'hostname' is known and matches the RSA host key. debug1: Found key in /cygdrive/f/progs/OpenSSH/home/.ssh/known_hosts:1 debug1: ssh_rsa_verify: signature correct debug1: SSH2_MSG_NEWKEYS sent debug1: expecting SSH2_MSG_NEWKEYS debug1: SSH2_MSG_NEWKEYS received debug1: Roaming not allowed by server debug1: SSH2_MSG_SERVICE_REQUEST sent debug1: SSH2_MSG_SERVICE_ACCEPT received debug1: Authentications that can continue: publickey debug1: Next authentication method: publickey debug1: Trying private key: /cygdrive/f/progs/OpenSSH/home/.ssh/id_rsa debug1: Offering DSA public key: /cygdrive/f/progs/OpenSSH/home/.ssh/id_dsa debug1: Authentications that can continue: publickey debug1: No more authentication methods to try.

  • Adding an Admin user to an ASP.NET MVC 4 application using a single drop-in file

    - by Jon Galloway
    I'm working on an ASP.NET MVC 4 tutorial and wanted to set it up so just dropping a file in App_Start would create a user named "Owner" and assign them to the "Administrator" role (more explanation at the end if you're interested). There are reasons why this wouldn't fit into most application scenarios: It's not efficient, as it checks for (and creates, if necessary) the user every time the app starts up The username, password, and role name are hardcoded in the app (although they could be pulled from config) Automatically creating an administrative account in code (without user interaction) could lead to obvious security issues if the user isn't informed However, with some modifications it might be more broadly useful - e.g. creating a test user with limited privileges, ensuring a required account isn't accidentally deleted, or - as in my case - setting up an account for demonstration or tutorial purposes. Challenge #1: Running on startup without requiring the user to install or configure anything I wanted to see if this could be done just by having the user drop a file into the App_Start folder and go. No copying code into Global.asax.cs, no installing addition NuGet packages, etc. That may not be the best approach - perhaps a NuGet package with a dependency on WebActivator would be better - but I wanted to see if this was possible and see if it offered the best experience. Fortunately ASP.NET 4 and later provide a PreApplicationStartMethod attribute which allows you to register a method which will run when the application starts up. You drop this attribute in your application and give it two parameters: a method name and the type that contains it. I created a static class named PreApplicationTasks with a static method named, then dropped this attribute in it: [assembly: PreApplicationStartMethod(typeof(PreApplicationTasks), "Initializer")] That's it. One small gotcha: the namespace can be a problem with assembly attributes. I decided my class didn't need a namespace. Challenge #2: Only one PreApplicationStartMethod per assembly In .NET 4, the PreApplicationStartMethod is marked as AllMultiple=false, so you can only have one PreApplicationStartMethod per assembly. This was fixed in .NET 4.5, as noted by Jon Skeet, so you can have as many PreApplicationStartMethods as you want (allowing you to keep your users waiting for the application to start indefinitely!). The WebActivator NuGet package solves the multiple instance problem if you're in .NET 4 - it registers as a PreApplicationStartMethod, then calls any methods you've indicated using [assembly: WebActivator.PreApplicationStartMethod(type, method)]. David Ebbo blogged about that here:  Light up your NuGets with startup code and WebActivator. In my scenario (bootstrapping a beginner level tutorial) I decided not to worry about this and stick with PreApplicationStartMethod. Challenge #3: PreApplicationStartMethod kicks in before configuration has been read This is by design, as Phil explains. It allows you to make changes that need to happen very early in the pipeline, well before Application_Start. That's fine in some cases, but it caused me problems when trying to add users, since the Membership Provider configuration hadn't yet been read - I got an exception stating that "Default Membership Provider could not be found." The solution here is to run code that requires configuration in a PostApplicationStart method. But how to do that? Challenge #4: Getting PostApplicationStartMethod without requiring WebActivator The WebActivator NuGet package, among other things, provides a PostApplicationStartMethod attribute. That's generally how I'd recommend running code that needs to happen after Application_Start: [assembly: WebActivator.PostApplicationStartMethod(typeof(TestLibrary.MyStartupCode), "CallMeAfterAppStart")] This works well, but I wanted to see if this would be possible without WebActivator. Hmm. Well, wait a minute - WebActivator works in .NET 4, so clearly it's registering and calling PostApplicationStartup tasks somehow. Off to the source code! Sure enough, there's even a handy comment in ActivationManager.cs which shows where PostApplicationStartup tasks are being registered: public static void Run() { if (!_hasInited) { RunPreStartMethods(); // Register our module to handle any Post Start methods. But outside of ASP.NET, just run them now if (HostingEnvironment.IsHosted) { Microsoft.Web.Infrastructure.DynamicModuleHelper.DynamicModuleUtility.RegisterModule(typeof(StartMethodCallingModule)); } else { RunPostStartMethods(); } _hasInited = true; } } Excellent. Hey, that DynamicModuleUtility seems familiar... Sure enough, K. Scott Allen mentioned it on his blog last year. This is really slick - a PreApplicationStartMethod can register a new HttpModule in code. Modules are run right after application startup, so that's a perfect time to do any startup stuff that requires configuration to be read. As K. Scott says, it's this easy: using System; using System.Web; using Microsoft.Web.Infrastructure.DynamicModuleHelper; [assembly:PreApplicationStartMethod(typeof(MyAppStart), "Start")] public class CoolModule : IHttpModule { // implementation not important // imagine something cool here } public static class MyAppStart { public static void Start() { DynamicModuleUtility.RegisterModule(typeof(CoolModule)); } } Challenge #5: Cooperating with SimpleMembership The ASP.NET MVC Internet template includes SimpleMembership. SimpleMembership is a big improvement over traditional ASP.NET Membership. For one thing, rather than forcing a database schema, it can work with your database schema. In the MVC 4 Internet template case, it uses Entity Framework Code First to define the user model. SimpleMembership bootstrap includes a call to InitializeDatabaseConnection, and I want to play nice with that. There's a new [InitializeSimpleMembership] attribute on the AccountController, which calls \Filters\InitializeSimpleMembershipAttribute.cs::OnActionExecuting(). That comment in that method that says "Ensure ASP.NET Simple Membership is initialized only once per app start" which sounds like good advice. I figured the best thing would be to call that directly: new Mvc4SampleApplication.Filters.InitializeSimpleMembershipAttribute().OnActionExecuting(null); I'm not 100% happy with this - in fact, it's my least favorite part of this solution. There are two problems - first, directly calling a method on a filter, while legal, seems odd. Worse, though, the Filter lives in the application's namespace, which means that this code no longer works well as a generic drop-in. The simplest workaround would be to duplicate the relevant SimpleMembership initialization code into my startup code, but I'd rather not. I'm interested in your suggestions here. Challenge #6: Module Init methods are called more than once When debugging, I noticed (and remembered) that the Init method may be called more than once per page request - it's run once per instance in the app pool, and an individual page request can cause multiple resource requests to the server. While SimpleMembership does have internal checks to prevent duplicate user or role entries, I'd rather not cause or handle those exceptions. So here's the standard single-use lock in the Module's init method: void IHttpModule.Init(HttpApplication context) { lock (lockObject) { if (!initialized) { //Do stuff } initialized = true; } } Putting it all together With all of that out of the way, here's the code I came up with: using Mvc4SampleApplication.Filters; using System.Web; using System.Web.Security; using WebMatrix.WebData; [assembly: PreApplicationStartMethod(typeof(PreApplicationTasks), "Initializer")] public static class PreApplicationTasks { public static void Initializer() { Microsoft.Web.Infrastructure.DynamicModuleHelper.DynamicModuleUtility .RegisterModule(typeof(UserInitializationModule)); } } public class UserInitializationModule : IHttpModule { private static bool initialized; private static object lockObject = new object(); private const string _username = "Owner"; private const string _password = "p@ssword123"; private const string _role = "Administrator"; void IHttpModule.Init(HttpApplication context) { lock (lockObject) { if (!initialized) { new InitializeSimpleMembershipAttribute().OnActionExecuting(null); if (!WebSecurity.UserExists(_username)) WebSecurity.CreateUserAndAccount(_username, _password); if (!Roles.RoleExists(_role)) Roles.CreateRole(_role); if (!Roles.IsUserInRole(_username, _role)) Roles.AddUserToRole(_username, _role); } initialized = true; } } void IHttpModule.Dispose() { } } The Verdict: Is this a good thing? Maybe. I think you'll agree that the journey was undoubtedly worthwhile, as it took us through some of the finer points of hooking into application startup, integrating with membership, and understanding why the WebActivator NuGet package is so useful Will I use this in the tutorial? I'm leaning towards no - I think a NuGet package with a dependency on WebActivator might work better: It's a little more clear what's going on Installing a NuGet package might be a little less error prone than copying a file A novice user could uninstall the package when complete It's a good introduction to NuGet, which is a good thing for beginners to see This code either requires either duplicating a little code from that filter or modifying the file to use the namespace Honestly I'm undecided at this point, but I'm glad that I can weigh the options. If you're interested: Why are you doing this? I'm updating the MVC Music Store tutorial to ASP.NET MVC 4, taking advantage of a lot of new ASP.NET MVC 4 features and trying to simplify areas that are giving people trouble. One change that addresses both needs us using the new OAuth support for membership as much as possible - it's a great new feature from an application perspective, and we get a fair amount of beginners struggling with setting up membership on a variety of database and development setups, which is a distraction from the focus of the tutorial - learning ASP.NET MVC. Side note: Thanks to some great help from Rick Anderson, we had a draft of the tutorial that was looking pretty good earlier this summer, but there were enough changes in ASP.NET MVC 4 all the way up to RTM that there's still some work to be done. It's high priority and should be out very soon. The one issue I ran into with OAuth is that we still need an Administrative user who can edit the store's inventory. I thought about a number of solutions for that - making the first user to register the admin, or the first user to use the username "Administrator" is assigned to the Administrator role - but they both ended up requiring extra code; also, I worried that people would use that code without understanding it or thinking about whether it was a good fit.

Any help is much appreciated, thanks! edit: using Apache & Passenger 2.2.4

  • Autocomplete jQuery on User Controller within Repeater .NET

    - by TheDPQ
    I have a Multiview search feature on a Web User Controller that is called within a Repeater, OHMY!! I have some training sessions being listed out on a page, each calling an employeeSearch Web User Controller so people can search for employees to add to the training session. I have the Employee Names and Employee IDs listed out in JS on the page and using the jQuery autocomplete i have them search for the employee and populate a hidden field in the User controller. Once the process is done they have the option of adding yet another employee. So i had Autocompelte 'work' in all the employee search boxes, but one i do the initial search (postback) autocomplete won't work again. Then i updated $().ready(function() to pageLoad() so it works correctly on multiple searches but only in the LAST item of the repeater (jQuery is loaded on the User Controller) FYI: I have the JS string set as EMPLOYEENAME|ID and jQuery displays the Employee Name and if they select it throws the ID in a ASP:HIDDEN FIELD <script type="text/javascript"> format_item = function(item, position, length) { var str = item.toString().split("|", 2); return str[0]; } function pageLoad() { $("#<%=tb_EmployeeName.ClientID %>").autocomplete(EmployeeList, { minChars: 0, width: 500, matchContains: true, autoFill: false, scrollHeight: 300, scroll: true, formatItem: format_item, formatMatch: format_item, formatResult: format_item }); $("#<%=tb_EmployeeName.ClientID %>").result(function(event, data, formatted) { var str = data.toString().split("|", 2); $("#<%=hf_EmployeeID.ClientID %>").val(str[1]); }); }; </script> I can already guess that by repeating pageLoad within the User Controll i override the previous pageLoad. THE QUESTION: Is there a way around this, a way to have all the jQuery appear in a single pageLoad or to somehow have a single jquery call to handle all my search boxes? I can't move the jQuery into the page calling all the controllers because i have no way of referencing the specific *tb_EmployeeName* textbox AND *hf_EmployeeID* hidden field. Thank you so much for any help or insight you can give me into this problem. This is the Multiview that on the User Controller <asp:MultiView ID="mv_EmployeeArea" runat="server" ActiveViewIndex="0"> <asp:View ID="vw_Search" runat="server"> <asp:Panel ID="eSearch" runat="server"> <b>Signup Employee Search</b> (<i>Last Name, First Name</i>)<br /> <asp:TextBox ID="tb_EmployeeName" class="EmployeeSearch" runat="server"></asp:TextBox> <asp:HiddenField ID="hf_EmployeeID" runat="server" /> <asp:Button ID="btn_Search" runat="server" Text="Search" /> </asp:Panel> </asp:View> <asp:View ID="vw_Confirm" runat="server"> <b>Signup Confirmation</b> <asp:FormView ID="fv_EmployeeInfo" runat="server"> <ItemTemplate> <%#(Eval("LastName"))%>, <%#(Eval("FirstName"))%><br /> </ItemTemplate> </asp:FormView> <asp:Button ID="btn_Confirm" runat="server" Text="Signup this employee" /> &nbsp; <asp:Button ID="btn_Reset3" runat="server" Text="Reset" /> </asp:View> <asp:View ID="vw_ThankYou" runat="server"> <b>Thank You</b><br /> The employee has been signed up and an email confirmation has been sent out.<br /><br /> <asp:Button ID="btn_Reset" runat="server" Text="Reset" /> </asp:View> </asp:MultiView> UPDATE: I never did find an answer but i had to do a demo so i hacked together something that 'works', but feels sort of cheesy. I am still very much needed of a better question or better understanding.

  • How to Make a Game like Space Invaders - Ray Wenderlich (why do my space invaders scroll off screen)

    - by Erv Noel
    I'm following this tutorial(http://www.raywenderlich.com/51068/how-to-make-a-game-like-space-invaders-with-sprite-kit-tutorial-part-1) and I've run into a problem right after the part where I add [self determineInvaderMovementDirection]; to my GameScene.m file (specifically to my moveInvadersForUpdate method) The tutorial states that the space invaders should be moving accordingly after adding this piece of code but when I run they move to the left and they do not come back. I'm not sure what I am doing wrong as I have followed this tutorial very carefully. Any help or clarification would be greatly appreciated. Thanks in advance !

  • Add User to Database not working

    - by user1850189
    I'm really new to ASP.net and I am currently trying to create a registration page on a site. I was successful in adding a user to the database but I decided to add another feature into the code to check what userID's were available. For example, if a user deleted their account their userID would become available for use again. I'm trying to find the min value and the max value and add or subtract 1 depending on whether it is min or max. I can run the code I have written for this with no errors but the user is not added to the database. Can anyone help me figure out what I'm missing from my code to do this? EDIT Code adds a user to database but it adds the new user at -1 instead. I don't seem to be able to see where the issue is. If (aDataReader2.Read() = False) Then aConnection1 = New OleDbConnection(aConnectionString) aConnection1.Open() aQuery = "Insert Into UserDetails " aQuery = aQuery & "Values ('" & userID & "','" & userFName & "','" & userLName & "','" & userEmail & "','" & userUsername & "','" & userPassword & "')" aCommand = New OleDbCommand(aQuery, aConnection1) aCommand.ExecuteNonQuery() aConnection1.Close() ElseIf (min = 1) Then aConnection2 = New OleDbConnection(aConnectionString) aConnection2.Open() aCommand = New OleDbCommand(aQuery3, aConnection2) aDataReader2 = aCommand.ExecuteReader() userID = max + 1 aQuery = "Insert Into UserDetails " aQuery = aQuery & "Values ('" & userID & "','" & userFName & "','" & userLName & "','" & userEmail & "','" & userUsername & "','" & userPassword & "')" aCommand = New OleDbCommand(aQuery, aConnection2) aCommand.ExecuteNonQuery() aConnection2.Close() Else aConnection3 = New OleDbConnection(aConnectionString) aConnection3.Open() aCommand = New OleDbCommand(aQuery2, aConnection3) aDataReader2 = aCommand.ExecuteReader userID = min - 1 aQuery = "Insert Into UserDetails " aQuery = aQuery & "Values ('" & userID & "','" & userFName & "','" & userLName & "','" & userEmail & "','" & userUsername & "','" & userPassword & "')" aCommand = New OleDbCommand(aQuery, aConnection3) aCommand.ExecuteNonQuery() aConnection3.Close() lblResults.Text = "User Account successfully created" btnCreateUser.Enabled = False End If Here's the code I used to get the max and min values from the database. I'm getting a value of 0 for both of them - when min should be 1 and max should be 5 Dim minID As Integer Dim maxID As Integer aQuery2 = "Select Min(UserID) AS '" & [minID] & "' From UserDetails" aQuery3 = "Select Max(UserID) AS ' " & [maxID] & "' From UserDetails"
