I have a .net 1.1 ASP application (domain.com) which has a .net 2 virtual directory (domain.com/v2) beneath it, both applications run within their own app pool on the same Windows Server 2003 machine running IIS 6. The web.config files for both apps are setup for Forms Authentication as described here - [URL]
Users would be directed to the domain.com/v2/login.aspx page which would authenticate for both applications, this configuration has been working fine for the last few years until installing one of the recent Windows 2003 security updates today. Now after authenticating under /v2 users keep getting redirected back to domain.com/v2/Login.aspx as domain.com doesnt see them as authenticated anymore.
which security update would have caused this and if its possible to fix or rollback?
Here I am using forms authentication and I have used an access database. I have put the db in App_Data folder and declared the connectionstring in web.config. The problem I am facing is that when I request any page without logging in the browser displays the requested page. At the bottom of the page there is a script error when I check the details it says Sys is not defined. Has this something to do with this issue??
In web.config file I have added the following lines in the <system.web></system.web> section.
On login button click after comparing userid & password I am using the foll stmts:-
If code = 0 Then ' code 0 means match for userid and pwd FormsAuthentication.RedirectFromLoginPage(txtuserid.Text, False) Else Response.Redirect("~/Default.aspx") End If
Recently I've implemnted Single SignOn feature in my website which was developed on Framwork 2.0 using visual studio 2005.These website works on all browsers perfectly except that there two systems in my testing environment where the FormsAuthentication doesn't work on IE only.
On Those systems itself FormsAuthentication works for other browsers like mozilla.On these system I have checked that FormsAuthentication cookie is created but it lost it value as soon as other page is traversed.But when I try to login again it give me the messsage that user is already login i.e. user was able to login successfully.Both of them are currenlty using IE 8.
I have implemented the .Net Membership provider with my website which is, for the most part, working well. However, occasionally a user will try and login and nothing will happen. There will be no error, they will just hit "Submit" from the login screen and continue to the homepage as an unauthenticated user. This behavior persists until they clear their web cache, or restart their machine... which makes me think it's some kind of cookie expiration error?
Does anyone have any ideas on how to troubleshoot this?
I have a web app that allows users to upload images. Last week, all was well. This week, it appears the code is breaking. Here is the code:
Protected Sub btnUpload_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnUpload.Click If FileUploadControl.HasFile Then Dim month As String = ddlMonth5.SelectedValue Dim year As String = ddlYear7.SelectedValue ' Dim whatis As String = FileUploadControl.PostedFile.ContentType Try If (FileUploadControl.PostedFile.ContentType = "image/jpeg") Or (FileUploadControl.PostedFile.ContentType = "image/pjpeg") Or (FileUploadControl.PostedFile.ContentType = "image/gif") Or (FileUploadControl.PostedFile.ContentType = "image/x-png") Then Dim fs = New FileStream(FileUploadControl.PostedFile.FileName, FileMode.Open, FileAccess.Read) 'save file with new size Using image As System.Drawing.Image = System.Drawing.Image.FromStream(fs) Using bitmap As New Bitmap(image) bitmap.Save("C:WebsitesimagesCusRespData.jpg", image.RawFormat) bitmap.Save("C:Websitesimages" & month & year & "CusRespData.jpg", image.RawFormat) End Using End Using StatusLabel.Text = "Upload status: File uploaded!" fs.Close() fs = Nothing Else StatusLabel.Text = "Upload status: Only .jpg,.jpeg,.gif and .png files are accepted!" End If Catch ex As Exception StatusLabel.Text = "Upload status: The file could not be uploaded. The following error occured: " & ex.Message End Try StatusLabel.Visible = True End If End Sub
On the development side, I see this error: The file could not be uploaded. The following error occurred: Could not find a part of the path. On the production side, this occurs: The following error occured: A generic error occurred in GDI+.
Until the Dec 29th my website was working fine. Then My fileupload problems started happening. My fileupload page would simply quit and say the page can not be found. I maximized all my timeout settings and that did not work. I called my hosting company and apparently they have no problem using my page to upload files from their geographical area. So then I concluded it might be a network problem. I ran a trace route and could not really figure out where the problem was. So, I have no idea what is going on. Is it possible that my site is being blocked by some black list out there somewhere?
I have a c# control class inside of a dll, then this control is embedded in a web page in an asp.net application by using the object tag. When the dll is compiled with .net 3.5 sp1 and the web application also runs in .net 3.5 sp1, the code works fine. But when the dll is compiled in .net 4.0 and the web application runs in 4.0, the control does not show up in the web page. All I see is a box with an object icon in the upper left corner.
Iam working on VWD express 2010, and things were going well, when the VWD crashed.I recovered my work and and realized that my controls stoped firing events.I removed and added button again, but in vain. I set "AutoEventWireup" and reset it also, but no use.I changed the code onto multiple systems. But the events wont fire. (I kept breakpoints also) My Web.config looks like this
I have been using a datagrid on various pages. For some reason it stopped working. When pressing the Edit to make a change to the record, the page posts back two times and the record does not go into the edit mode. I am using IE 7 for my browser. Below is my code.
I'm still building). After loggin in, users are presented with 3 radio buttons (they work), and 3 cascading drop downs (they work). Below that is an AJAX Accordion with 5 panes, each pane has a tabpanel with 4 tabs, 2 of the tabs have gridviews that change based on who is logged in and the radio buttons and dropdowns above
I have designed a basic web user control to enter some values in a table. The control worked fine if it is used without similar control on same page. When another instance is pasted with different id, then both stopped working.
I've found this article on enabling windows authentication within an intranet ASP.NET application. I did exactly what the article says, and when I go to the page on the server all it does is prompt me for a username and password, which I would assume means that it is seeing me as an anonymous user and not a windows user (which is not true).
In my application on the IIS i have the "Integrated Windows Authentication" box checked and this is what I have for my web.config file:
[Code]....
I've also tried this before and got the same results:
[Code]....
I have no idea what I need to do to get this to authenticate correctly. I've been banging my head off a wall for the past 2 days on this issue.
I have a basic intranet website for my company but there is one page that cannot allow anonymous as I need to grab the user's login. I created the site and everything works perfectly on my development machine. once moved to the production server it no longer works.
Here is the problem: I can get the login prompt when going to the secure page, but when trying to login I get a "401.1 - Unauthorized", even when trying to login as a server administrator. Here is the authentication portion in my web.config:
[Code]....
I have done this before and always gotten it to work. I hope I am just missing something very simple...
I'm trying to write a simple ASP.NET 4.0 app, using Windows authentication to login. This is on my peer-to-peer home network. When I click to login, it instantly shows my Windows identity, so it looks as though I don't even need to login, as it's already done that for me. However when I then go to any other page in the app, it looks as though I'm not logged in. Why is that and how do I fix it?
I have created a we app. using win authentication. When type the server ip addres in chrome I get the login window and it works just fine with my organizations credentials, however when doing the same using Internet Explorer I have to login with the server credentials as my account is not valid.
Am in the middle of developing 2 projects and my AJAX Toolkit has stopped working, which is also stopping my designer filers being generated. Have the same problem in both projects. A sample error is below: Warning 3 Generation of designer file failed: Unable to create type 'cc1:CollapsiblePanelExtender'. Could not load file or assembly 'System.Web.Extensions, Version=1.0.61025.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' or one of its dependencies. The system cannot find the file specified.

I know this is working correctly beacuse when I publish my website to my hosting provider, and request a resource in a protected directory, and I am not currently authenticated, I get automatically redirected to my login page and then once successfully authenticated granted access and redirected back to the sure *.aspx file in my protected directory (assuming I am authorized for those resources).
So that is working no problem.
However, when I run this from visual studio 2008 (F5) in debug mode, I am not being required to authenticate. It simply serves up the protected resource without asking for my credentials.
If I put a [PrincipalPermission(SecurityAction.Demand, Authenticated = true)] on a BLL class method, it will throw an security exception, but the page that is calling it is in a secure directory and I am never asked to authenticate using the login page.
I am closing and re-opening brosers, clearing cookies, etc..., but no matter what I do I am not automatically redirected to the login page, and the secure page when I launch from visual Studio running on the embedded local host. Thiis working perfectly externally, same build, same web.config, pointing to the same database, on the hosting provider. (yes, eventually, I will be using dev/test/prod db configurations to test, but for now for simplicity I am keeping it the same)
Not only is it maddening, but worse yet, it would obviously make testing this application impossible after the initial release.
I've just upgraded a visual studio.net 2003 project (asp.net 1.1) to visual studio.net 2010 (asp.net 4.0). I'm encountering a problem with viewing Crystal reports. I'm using Visual Studio Development Server as a Web Server.
When I try to create a new report (via code that worked fine previously) the line below causes the webserver40.exe to crash.

I'm just getting started with MVC and I created a new MVC 2 C# project. Visual studio defaults it to .net 4 but since my hosting provider is still on 3.5 I went into properties and set my project to target .net 3.5. However when I did this a piece of my code stopped working.
I have an HttpHandler which takes care of 404 errors, which I implemented years ago as a way of doing url routing. If the request maps to a valid page, it redirects to that page. Otherwise, it returns a 404. (I know I should start using the new routing feature of asp.net 4.0, but that will take some time. I need to get this working asap.)
In IIS6, I have mapped the 404 error to "/404.ashx". In the web.config, custom errors are set up like so:
This has been working for years - it stopped working as soon as I changed the site to use asp.net 4.0. Everything was recompiled for 4.0, and there were no code changes.
Now, when I hit one of these urls that used to work, I get a blank page with a 404 error code. If I remove the IIS 404 error mapping, I get a regular old 404 page. It seems that the httphandler is not being called.
I have other http handler which are working fine. I figure there must be some configuration setting I missed or something like that. Naturally, this is a problem only on my production server, so I can't run it in the debugger to see what is happening.
I have some services deployed on [URL]I want to move them to [URL]. I have [URL] physically hosted & has its own web.config file. No inheritance issues...
I configured the subdomain (through my host--I don't actually own the web server) so that the subdomain is physically hosted & made sure it's running as an IIS application.
When the services lived on [URL], I used the following address prefixing in web.config:
[Code]....
Now that they're on [URL], I modified the web.config to read:
I'm having a problem with my 3rd cascading dropdown no longer displaying the list. I've obviously made a change somewhere but I cannot see it so I'm hoping some extra eyes will spot the problem. If it matters, I am using VWD 2010 Express, SQL Express, .NET 4.0I have checked the datasets and they are returning the proper list based on the input criteriahere is the pertinent code:
