C# - Logging Changes Using LINQ To SQL?
Feb 23, 2011
In a system I am creating, the customer requires all changes to data to be logged to a database table - with only changes being logged (i.e. if they only change 1 value on a form full of 10 fields, it'll only audit that one change). So essentially I need to be able to compare the old values to the new values.
This is of course easy - I've done this before, but it was rather messy - I would manually check each field in the database and compare it to the new one to decide if it should be audited. Is there any easier way, of perhaps automatically getting the changed column name/values? Or do I have to do it my 'messy' way?
Pretty much all of the changes to be logged are done using LINQ to SQL - so perhaps there's a way to compare the database table to the modified one, before calling submit changes?

I have this query and its result implements IEnumerable.
[Code]....
**Question** : How to get generated SQL from this query, or how to convert its type to ObjectQuery to use routesQuery.ToTraceString(). Is it possible?**Reason** : I want to log all SQL queries to DB, though I don't want to create new object for joined contexts (tables)**Important** : I can't use ObjectQuery initially because after all I use
ListView.DataSource = routesQuery;
ListView.DataBind()
And it can cause an error of using to different contexts (DB tables) for one datasource.So what should I do get generated SQL query?

I have this query and its result implements IEnumerable.
RoutesEntities routesModel = new RoutesEntities();
LocalesEntities localesModel = new LocalesEntities();
var routesQuery = from rs in routesModel.Routes.ToList()
join ls in localesModel.Locales.ToList()
on rs.LocaleID equals ls.LocaleID
select new
{
LocaleID = rs.LocaleID,
RouteName = rs.RouteName
};

I'm debugging some unexpected behavior and while tracing in to the .NET framework I see a bunch of stuff like this:
if (Logging.On) {
Logging.PrintInfo(Logging.Web, this, SR.GetString(SR.net_log_n_certs_after_filtering, filteredCerts.Count));
...
}
But (as expected by default) the execution steps right over these. Is there some way to turn on the logging? Or is that just something that the framework developers can do while making special builds of the framework?

I'm using MS Enterprise Logging Application Block in an ASP.NET website.
For production launch, I will set up a log listener in one of these locations:
Sql Server database
Windows event log
Text files
Which has the least impact on performance?
NB - I can't switch to Log4Net or ELMAH at this point, so don't suggest that in your response.

I spent a day trying to make Ent Lib Logging work and log anything into database or event log. I have a web application and console application with the same Ent Lib config but only the console application is capable to log into the Event Log. I tried everything with permissions but I don't know what exactly I am doing — which services should have what. It does not work!
I read articles like this[URL] and I want to try to give the ASPNET account those permissions. I am using Windows 7 and I cannot find ASPNET user account. So where is it?
This is the config file which is automatically generated from Ent Lib utility and it works only on App.config, not on web.config:

I have a login page, I login like I should and everything works.I logout and when I type/paste the address to the page, in the address field, I still reach it just like if I was still logged in..The page I type in the address field is in a subfolder, only suppose to be able to be reached by logged in users and in this folder,ith it's own web.config-file:
<?xml version="1.0"?>

I was adding login and logout functionality to my ASP.NET website. While I am able to make the user log in by checking the username and password but on some pages should be available only if he is logged in. I am doing this by storing the user's value in a session
Secondly, I am using a Link button which changes to Logged in as example. So, how does the user log out?

I've been working on my personal website as of late, and even thought it's not a big problem because I'm the only one that sees it, it's annoying nonetheless.
Whenever I go to my login page, it all works fine. If I enter a bad username/password, it will just print a simple text message error(intended). But, if I login correctly, then instead of redirecting to the root of my website as I intend, it will instead create a new tab in firefox and from there it will be in / (which is correct). The problem is why does it create a new tab? I didn't even think forms were capable of such a thing:
My full login page is at [URL] The gist of it is:
<form method="post" target="/login">
Username: <input type="text" name="username" /> <br />
Password: <input type="password" name="password" /> <br />
<input type="submit" name="Submit" />
</form>
And my server side code is also very simple:
if(RouteID=="login"){
if(AuthenticationModule.Login(Form["username"],Form["password"],false)){
//logged in correctly
Response.Redirect("/"); //just go to the root of my site
}else{
Write("You fail at life");
}
}

I am providing registered members of a website a weekly mailing which contains URLs to private pages on the website.
For usability purposes, I don't want the user to have to provide their credentials after they click on the URL.
I am using the ASP.NET Membership provider model.
Question
How can I implement this so that the user can be logged in by virtue of clicking a specialized URL link?

I wan't to connect to remote web page (that has login form) with HttpWebRequest. I am using this tutorial: http://www.byteblocks.com/page/How-to-submit-requests-to-web-sites-programatically-using-HttpWebRequest.aspx
,but I don't know where RequestAttributes class belongs to?!? Is there any better way to do this? The remote page is in ASP.NET, it's using Form authentication and when someone makes a request to default.aspx it redirects it to login page. I want to parse default.aspx page, but before I am able to do that, I need to pass credentials to login form via POST method in HttpWebRequest. Here is another example using POST method to pass parameters: http://www.worldofasp.net/tut/WebRequest/Working_with_HttpWebRequest_and_HttpWebResponse_in_ASPNET_114.aspx
but I don't understand why this does not work in ASP.NET remote page.

I've just starting looking at a site in place at work. They're using Elmah to log errors.It seems to be logging fine, but in the web interface, when I tell Elmah to show me 100 errors per page, it only shows the most recent 15.Then when I click on "Download Log" I only get shown 15 errors in the CSV.Anyone know how I can configure it to keep all the errors?Or can someone point me to some docs on how to do this?

I'm trying to create a setup in my ASP.NET website that allows me to enable/disable logging while the application is running at any point. I figure some of you have already done such a thing.
Here's the gist of what i'm trying to do:
if(ShouldBeLogging)
logger.Info("helloooooo there");
So how would you set up the boolean value ShouldBeLogging to be able to be turned on/off while the website is running without getting any serious performance drawbacks(seeing how its going to be accessed frequently)? I was thinking about putting something in the web.config, but wouldn't a change to that kick my user sessions if i wanted to turn it on?

We are bulding an intranet for our company. Just to do things like log support calls, keep details of customers servers, computers etc.
What i want to do is have a table that will record changes for each page. If we have the servers table, if somebody updates the ipaddress i would like it to log the previous value, the date and time, the user that did it, the new value and what table and field they changed. Is this kind of thing possible? i would imagine i would need some code that would execute on the insert command that would programatically insert the details into the changes table.

As part of a master page template, several sites include a login control. Since the site is served over HTTP, I want the login control, once a successful login has been achieved, to resolve to a portal served over HTTPS.The closest I've seen to achieve this may be here, but I'm not entirely clear on its implementation.Can I get some feedback or suggestions on this?Of course, a simple "Login" link on all pages that point to a login paged served over HTTPS is another solution, but this is not what I'm looking for.

I want to log errors with System.Diagnostics.TraceSource and wonder which Listener I could use and how to configure it so that it logs to Log Files in a specified directory. A new log file should be created when the log reaches a specific size.Is there an exisiting listener that does this? Or something that comes close? know logging to Windows Event Log is best practice, but I cannot easily access the log on the server, so using files I can download through FTP seem to be the best solution.

I'm trying to create a log that would keep a history of changes for a given item. For example on [HttpPost] Edit page I would log a change for a given article. So i've created a filterAttribute that would execute once the Edit action has completed successfully:
public class LogAttribute : ActionFilterAttribute
{
private int type; [code]...
I tried this:
filterContext.ActionDescriptor.GetParameters()
but this only returns "strings" as a parameter. "objectId" however is stored in a hidden field on the edit page.

I am using standard ASP.net security and want to how I go about prventing the same user from logging in twice.
If the user is already logged in and they log in again what I want to happen is for them to cancel the previous session and log that session out.
Can this be written into the webconfig file as part of the membership profile? I have tried to find this and it does not seem to be possible.
