I am developing an ASP.NET application that takes user input and serializes them into a text file. Now, when a second update request comes while the file is still being written, an IOException will be generated.How do I handle concurrent update request to this file?
ASP.net radiobutton change event writes the new selection to an XML file and that needs to be shown on the page but does not show the changes on the page since the page load occur before the event fires. give some insight how to resolve this.
The file system I'm publishing to is a not hosted by me, but by my university. IT here offers students their own web directory to host a website. My intention is to use it to host projects for classes and demo them for my professors. You can enter in a specific link in any browser to go to this website and view it as long as there is a file named 'index.html' in the directory with some presentable html code.
So here's the problem. I want my website to be written using ASP.NET and when I use VS2010 to publish my ASP.NET website to the 'File System,' I cannot simply open up my browser, type in the normal link, and have it display. It just shows up as a list of files in the directory and I can see all my source code for the web site
I have a few app settings I want to update from within my web site and to do this I use this code:

This works fine in my development enviroment but when using IIS7 I get an exception while saving these settings:Access to the path 'C:InetpubwwwrootNSiteCOMweb.config' is denied.How can I configure IIS7 to allow my application to update web.config?
THE CODE: Session["foo"] = "bar"; Response.Redirect("foo.aspx");
THE PROBLEM:
When foo.aspx reads "foo" from the session, it's not there. The session is there, but there's no value for "foo". I've observed this intermittently in our production environment. But I don't mean here to ask a question about Response.Redirect().
THE EXPLANATION:
Bertrand Le Roy explains (the bolding is mine): Now, what Redirect does is to send a special header to the client so that it asks the server for a different page than the one it was waiting for. Server-side, after sending this header, Redirect ends the response. This is a very violent thing to do. Response.End actually stops the execution of the page wherever it is using a ThreadAbortException. What happens really here is that the session token gets lost in the battle. My takeaway there is that Response.Redirect() can be heavy-handed with ending threads. And that can threaten my session writes if they occur too near that heavy-handedness.
THE QUESTION:
What about ASP.NET session management makes it so vulnerable to this? The Response.Redirect() line of code doesn't begin its execution until the session write line is "finished" -- how can it be such a threat to my session write? What about the session write doesn't "finish" before the next line of code executes? Are there other scenarios in which session writes are similarly (as though they never occurred) lost?
I have a website on visual studio 2008 on my local machine. When I run through the debugger I get the following error, however when I browse the same website through the IIS manager (running IIS7.5), I can browse it. What do I need to fix to run it through debugger? The website is set as an application.
Error:
Configuration Error
Description:
An error occurred during the processing of a configuration file required to service this request. review the specific error details below and modify your configuration file appropriately.
I get this error while trying to run my project: "Column name 'UserID' appears more than once in the result column list." Indeed, the query generated in my SqlTableProfileProvider.vb is the following (text in brackets [] has been changed):
"IF EXISTS (SELECT 1 FROM [table] WHERE UserId = @UserId) BEGIN UPDATE [table] SET UserID=@Value0, LastUpdatedDate=@LastUpdatedDate WHERE UserId = '[Guid]'END ELSE BEGIN INSERT [table] (UserId, UserID, LastUpdatedDate ) VALUES ('[Guid]', @Value0, @LastUpdatedDate) END"
I'll emphasize that the above statement is generated in SqlTableProfileProvider.vb, which was written by .Net people. While I have little control over its source, I've apparently given the fodder whereby the mistake can be generated. Any clues as to why UserID is being written twice in the statement?
I want to make a 2nd website and am using a copy of the site files from my 1st site built for me, I added them via FTP to the hosting company. I realise when I edit the new site via the CMS it is editing both sites plus when I try to change anything to the CSS file I get the following error -
So my questions are what do I need to change to be able to deploy a new site with the files I have to make a new site?I also don't understand where the password is coming from, I can see the User ID comes from the database. in the Asp.net connection strings are the following:
site Data Source=sql7.hostinguk.net;Initial Catalog=***;User ID=***;Password=*** - Where is this password coming from?
membership Data Source=sql7.hostinguk.net;User ID=***;Password=***;persist security info=False;initial catalog=***;
I'm trying to run a website (site2) that I've placed inside a folder (dir-site2) of another website (site1). The default file of site2 displays fine in every browser on my local computer, as in when I type http://localhost:45912/www.site1.com/dir-site2/default.aspx. But when I upload everything to my host's server and type this
http://www.site1.com/dir-site2/default.aspx I get a server "can't access" error message. I can't display any file that is inside the subdirectory, dir-site2.
I am working in a school and we recently installed a new server running WinServer 2008R2. I want to be able to point people to a URL on our intranet and have them fill out a simple registration form and have this data written to a database. It would also be nice to have some data auto-populate (such as their name).
Is it overkill to set up a sharepoint server and try to do this with Access Webforms? Could I use something like dotnetnuke and find a module that works? Or how about options for writing custom forms?
We recently migrated from VS 2008 to VS 2010. The migration went fine, except for our web project. Before, in VS 2008, the site showed up as http://localhost/Website. Now, it appears as C:...Website. It appears that when we did the migration, VS started to treat it as a file system website.
I've tried removing the existing site and re-adding it as an existing website, but it still displays it as C:...Website. Is there any way to convert it back to show it as a http://localhost/website, and run through IIS, as opposed to the default ASP.NET Development Server?
In the separate userSetting.config file I have some template user details. When a new user is crated the template details are stored in the userSetting.config file. I am trying to write to this filebut not having much luck.

I have built an ASP.NET (.NET v4) application in VS 2010. It is working just fine. But when I try to create deployment package (so I can deploy it in our test IIS 7.5 Server), it gives me error like this,
Error 1 Could not open Source file: Could not find file 'C:11-2 estobjDebugCSAutoParameterize ransformedWeb.config'. 0 0 test
Thing is in past, I had deployed the SAME application using the SAME method.
