C# - Use Authentication In 'Forms' And As Well In 'Windows' For A .net Web Application?
May 14, 2011
We have an application in Access for UI and MS Sql server as Database server. We now decided to build a new application in web application for UI. This web application is only used by the employees who work for the company. But later we decided to host this web application on outside server. So the user (from this company only.) can able to login anywhere in the world. First I thought creating the web application using 'windows' authentication thinking we may be using it as an intranet web application. But now my manager asked me to use both 'Forms' and as well as 'Windows' for using this application and this web application will be hosted on outside server. I really don't catch his point of using both types of authentication.
I am reading the article at: [URL].. Forms Authentication in ASP.NET 2.0". I am using VS 2008 and .Net Framework 3.5. I don't know if this makes a difference, so please let me know.
A user logs on to our system in the morning Based on their Windows Authentication, they can access several intranet applications. For a particular application, the user has to select their Organization or Position or Location.
Based on the user's Windows Authentication, once the user selects one of the three above and clicks a "Submit" button, a second page is launched that shows certain information about the selection based on the User's authentication.
For example, if User selects Organization, the following information will be returned based on the Organization THEY are a member of. They can not access information from OTHER organizations, ONLY their own based on their login credentials. This information returned as a result of the dropdownlist selected value includes: street address, city, state, zipcode, Bus. Unit #, etc. appears in labels on the second page.
The labels can be dynamically created at runtime. (I dont know if a User control can be created to do this, since the "Position" and "Location" will contain the same address information, and it doesn't matter at the moment). I just want to populate the labels on the second page (or on Postback) based on the User's log in credentials after they click the "Submit" button. Or, if they don't have to click a button, just have the information complete based on the selected value of the dropdownlist control.
I have a application that prints labels on a community computer.I would like to add a Windows authentication login form to allow any of our employees to access a configuration screen.The request would bring up the login form if the login passed (meaning the username / password was correct) the configuration form would open.Otherwise the user would just get a warning Msgbox.So far all of the examples I could find either apply ASP.NET or use the logged-in user. Not for additional access as I'm trying to do.
I am working on a windows application and I am developing application using VB.Net. I want to create one form for Username and password and I want to create a table in database which will contain all the user details with UID and Password. So I am planning to use either Windows authentication or SQL authentication on database side for allowing user to connect database with my application But I am curious to know the best practices which are widely used across. Can anyone share the blogs,articles or your own experiences.
I have a VB.Net project that I am running from a local server and I need to use the credentials the user is currently logged in with to upload a file to a folder I create on a SharePoint site on the same domain. I can get it to upload if I specify the credentials but it will not work with system.net.credentialcache.defaultcredentials. It just gives me 3 empty strings and I get a 401 unauthorized error. I have seen a few threads that say you cannot use it with Windows Forms Applications. Is this true? Here is my code:
Our company runs Windows Server 2008 R2 and as part of the normal login procedure you type your username and password. IT sets the domain when you get your PC so that is all good. So, when you open IE, the intranet sight detects that you are person XXX YYY and then logs you into the site automatically as the right person.
Now is there any way that I can do the same with an application written in C# or VB.NET. I.e., I would like the user to not have to log in as they have already done so during Windows log in, and then use the application as the individual user. This is for loggin purposes and specific rights for each group.
I have the following code being used, it is really useless for me as I can't get much info using it, is there any other way I can save the info when a user logs in to store it for the whole time until the program closes?

i'm developing a web application. i want if user access it, it will prompt for windows authentication, if the username and password is correct, then the page appears.i've been working around on this but it's not working. my web app prompt users for windows authentication, but it always failed or access denied.anything i should check?
I want to use windows authentication in my vb.net application rather than validating against Database. Is there any possiblitiies or APIs that allows me to use Windows authentication? I have user id and passoword text boxes. Once user entered the userid and password, it should validate again Windows authentication.
I have a basic three form application. It doesn't seem to close after navigating through forms. If I were to open the application, and the main form is displayed. If I press the X button, the application closes fine(Goes from processes) If I were to open the application, and then navigate from the main form to another form using me.hide & form1.show, and press the red X on Form1, the application again, closes fine.
I have the requirement to create an application that has multiple front ends developed using Windows Forms, WPF, ASP and Compact Framework Mobile Forms.I would like to be able to create a series of obejct representing the business logic and have this logic accessible from the various front ends available. My first thought was to use remoting as I'd like to be able to pass the business objects back and forth between client and server but the compact framework doesn't support remoting and also transferring a full framework business object to a compact framework business object doesn't seem possible.My next thought was to use web services but again the passing of business objects seems to be very hard to accomplish. Without doing this I would have to create individual web methods for each business operation.
Finally my next option is to use sockets and write the whole client/server logic within some classes and expose them to the UI/Business layer. My only problem with this is it is not scaleable should the number of clients increase dramatically whereas using remoting or web services I can host the solution via ASP.Net.Does anybody have an ideas on the best way forward for this or even have any input on how they would write an application that required a windows form, wpf, asp website and mobile device GUI all of which want to use the same business logic?
I'm porting code that I wrote for use in a Windows Forms application to a Windows Service, but for some reason, the code that worked in the Windows Forms application is now throwing errors in the Service
I am making a System Tray Application when i minimize my form its hide itself in the tray but whenever i click on the tray icon my form shows now when my form shows up i would like to disable my Background desktop same as CardSpace when its shows up.
I have a windows forms application written in VB.NET which scrapes information from serveral web pages (who doesn't right)? Anyway, I am having problem with one particular site where partway through the page navigation my application hangs. When I press pause (or break) in the debugger, it stops on a call to System.Windows.Forms.Application.DoEvents.
Resuming execution shows that it really is stuck on this line (it does not reach the next line of code). It also hangs about the same point each time I run it (at least its consistent). Since System.Windows.Forms.Application.DoEvents yields to other threads on the same processor and then resumes execution of the current thread, I think the problem is that some other thread is not behaving well (not returning from some event handling code). I thought Windows 7 was pre-emptive, which makes me doubt that theory but I really don't know.
[Code]...
The program scrapes somewhere between 12 and 14 pages before it gets stuck on the call to DoEvents. Does anyone have a clue why this would happen? Why would any call to DoEvents hang?
I am trying to use the System.Diagnostics.Process class.I have the following Windows Forms application. It consists of 1 Button and 1 TextBox. The only code is for the button click event as follows.
Public Class Form1 Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click Dim myProcess As New Process()
I have a fully functional multi-threaded VB2008 console application that I need to convert to a windows forms application. I am doing this to add additional functionality at a later time. How would I go about doing this?
My boss gave me an MS Access application that was developed by our former colleague. He wants me to convert that application to VB.Net Windows form application. I went through the MS Access Application. It contains tables, queries, forms, reports and macros. I could not find the programming (Where is the code written in MS Access?). My boss wants the windows application to be same as the MS Access Application (both in design and logic). I don't how will i develop the windows form. How can I achieve this?

When I try to use Windows auth, the pop-up tells me: X website required login for Y domain.How can I hide the website name? And only show "You are required to login first" text on that pop-up?
I have a .NET application (mix of C# and VB.NET) where I would like to display a Windows Login Dialog box (or my own dialog box) and authenticate the user using Windows Authentication. Per requirement, I need to ask the user to authenticate after AT LEAST a minute of being idle. I would prefer a .NET native way of doing Windows Authentication but interested in other ways...
how to use Windows Authentication in a WPF app. I wouldn't have thought that it would be any different than in any non-WPF app, but it seems that it is. I want to go into my project Properties -> Application and ensure that Windows Authentication is on, but that option is not available in a WPF app (as the following document confirms).

If I ignore all that and just look at My.User.Name (VB), it is empty. This tells me that somehow Windows Authentication is not enabled.My plan is to use a PrincipalPermission attribute to restrict access to certain parts of my app (or perhaps the entire app, by applying it to Application_Startup()).
I want to use windows authentication in my c-sharp desktop application.where I cloud use windows create new users service and allocate local storage space.
I'm writing an internal web application right now (with ASP.Net Web Forms), and it presents an odd problem. I have to be able to impersonate the currently logged in windows user, and execute a command based on their Windows Authentication to log in.. AND ... if they don't have Windows Authentication set up in the application I have to use to log them in, I have to be able to accept a user name and password. I also have to write the application in .Net 4.0, and secure it as much as possible. I got this to work by NOT utilizing Windows Authentication or Forms Authentication in the web.config, and instead setting session variables to guard against user accessing pages in the web app other that the log in. I did this by creating an oddly name session variable with a value based on their user name (windows auth or not), and then a secret session variable. The secret variable is in the web.config as a 256bit encrypted string, in which I decrypt, and set as the session secret. In order for the page to load, the first session variable can't be blank, and the second variable has to equal the decrypted key value... if the variables don't pass inspection, it redirects them to the login page. I set this up on every page, generic handler, and webservice method in the web app. I make the session timeout after a few minutes of no activity, and on log out, I set all session variables to nothing, and expire all cookies. (I also disable all cache).
My question is... Does this offer comparable security to that of Forms authentication? I have always used Forms authentication, but can't use it here. If I did, the users would have to reconfigure settings in IIS and in he web.config to toggle login procedures (From my knowledge, you can't use both Forms authentication, and windows authentication to manage the security of your pages and other web resources). With the method described above, I can accomplish the best of both worlds, but am curious about the security of my methods. Is there anything else I can implement here to assure the utmost security other that using forms authentication? Is it possible to accomplish the same level of security of Forms authentication without using it?
If I wanted to make sure that AUTHENTICATED users were denied access to Enroll.aspx and UNAUTHENTICATED users had access how should my "allow/deny users" tags be set in the web.config?[code]......
I write a dll some time ago that authenicated with a Windows Server 2003 Domain controller. Every thing worked fine. The IS group upgraded the domain controllers to Windows Server2008 R2 this weekend, now I can not authenicat anymore. It seems to have the correct LDAP path, when I get to the function that does the check for the user name i get the following error.
?_dsEntry.NativeObject A first chance exception of type 'System.DirectoryServices.DirectoryServicesCOMException' occurred in System.DirectoryServices.dll {"Logon failure: unknown user name or bad password. "}
I thought I had the command correct, but I wanted to make sure since I fail to connect in my app. Here is the connection command I use:New SqlConnection("Server=TestServer;Database=MasterDB;Integrated Security=SSPI")I have verified the server name, DB name, and that the server is using windows authentication.
On the server, I get my current logged-in username, but from a remote client I get server name/administrator.
Below is the code:
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load 'Grab username from Windows Authentication, remove the 'HHI', and assign to empName 'empname = Replace(HttpContext.Current.User.Identity.Name.ToUpper, "HHI", "") 'empname = Replace(Page.User.Identity.Name, "HHI", "")
[code]....
I've tried Application Pools with 'Network Service', with Named Accounts and setting the pipeline mode to 'Integrated' and 'Classic'. The above code works properly in Server 2003/IIS6, but I haven't been able to make it work on Windows Server 2008R2/IIS 7.5.
I buit a ASP page that gets the users information who is logged into the computer ie username etc. This was using IIS6 Now I've moved over to IIS7 on Server 08, I set it up to use "Widows Authentication", however when i run my ASP.NET Page it uses the account NT AUTHORITYNETWORK SERVICE to do its work.Ive looked all over online, and cant find a way to fix this.I just want to pass the user credetials from logging into the computer, to the web.I've made sure that I have this in my web.config
When I run this the site from Visual Web Developer and it creates the site, it pulls back the correct information.However, when I Then to my browser and check this and it dosent pull back the correct account, it pulls back that NT account.etc. but it always seems to pass the same wrong account NT AUTHORITYNETWORK SERVICE it should be my accountname I am logged in with.
