I have a pretty big web site (asp.net web) and I have used JavaScript intensively (jquery,custom javascipt, etc) and also The theme and CSS. Right now I have a huge amount of js and css files in my system and I am thinking about minifying and smashing the js and css to improve the performance. So, please advice me the suitable tools and technologies to be used and please suggest me the best practices to be applied in these scenario.
View 4 RepliesIn my webpage, the page uses lots of images and css. The time taken to load the initial home page is huge.What are the ways,which can be done in IIS 6.0 to improve the performance?I checked few results in google, which talked about File expiration policy and enabling http compression in IIS 6.0. In the Enable content expiration, what value should be ideally used?In the Custom Http header, what should be added to improve the performance.

View 3 RepliesWe are using MSChart on an ASP.net 3.5 web application and noticing significant slowness from enabling tooltips. the performance of drawing a chart is increased by 1,000-2,000ms.The chart output is PNG, and contains in total 108 data points.
View 1 RepliesI have developed a gridview which has 7,000 records with some filtering. However, theuser is compaining that it is too slow. It seems to me that if the records were stored in memory it would be much faster. This is caching, I think. Is that the case? Can you updaterecords this way? Can you cache with an Access database or do you have to use SQL Server? Can you think of any other ways to improve
View 11 RepliesI'm doing a timesheet program. In this timesheet program, I have a default button. If a person doing a same task everyday, they can just fill out the task description & click on default button, it will add that task for 5 days.my question is that my button click has to hit database 7 times. Is there anyway that I can improve this?

This is a continuation on this question:The problem is simple. I need to call methods from a REST web service which controls several tables. One table is a snapshot table which contains records with huge XML files. Each XML file is basically a backup from another database. This backup XML is then sent to customers who use the data as read-only information in another product. Basically, the data in the XML are lists of companies, products, business rules and whatever more. And no, those customers work offline most of the time, so they cannot get the data live.Walking through the list of snapshots is tricky: XMLData.Snapshots.Skip(N).Take(1).First(); but it works very nice. It's the answer of the previous Q.But there are three other lists of data that I need to walk through. These are called Changes, Errors and Messages. They contain (1) changes to the data, (2) errors that occurred during modifying the data and (3) generic messages. All of these records are linked to a snapshot record. Thus a single snapshot can contain multiple changes, errors and messages.
I still cannot access the server code but since there's a REST service wrapped around an entity framework exposing most of the functionality, I can still use that service. (And that service is only accessible internally, on the Intranet. This is basically what I have to work with. And while the lists of changes, errors and messages are relatively small, the snapshots are still huge.
The problem is that I now want to generate a client-side report of the changes, errors and messages, but without grouping them by snapshot! They need to be grouped by date. But each record also needs to show the title of the snapshot, which causes me some incredible headaches...When walking through e.g. the Changes with the regular foreach instruction I can load the Snapshot data by using XMLData.LoadProperty(Change, "Snapshots"); but since the snapshot record itself is generally about 300 MB, this just slows the whole thing down to a crawl. (There are tens of thousands of these records in total!) So I need a faster solution, without having to modify the server code.
Yeah, okay. Modifying the server would be the proper way but that's not possible. It's in production and this list isn't important enough to require an upgrade of the server. Basically, I'm not allowed to modify any server-code for now. (But they still want this list.)The application I'm working on is something that just needs to run once per week or per month. But with the current amount of records, I estimate it would take more than two days to finish. The data itself will be updated a few times every office day and snapshots are created every week or so on the server. Errors can always be generated when users start browsing the site which maintains the data but in general, there will be about 50 changes and 4 errors per week, plus a few messages when the server goes down and up again or when snapshots are generated.

Both the applications are using the same service then way there is a time span problem. Please suggest me what can I do to improve performance of application A?
I'm experiencing a to me mysterious error when sending e-mails through a SMTP-server from an ASP.NET web application. I get the famous error "unable to relay for xxx@yyy.zzz". What's mysterious to me is that when I cut and paste the exact same code that sends the e-mail into an usual .NET Windows Forms application, send the e-mail with this application, it all works just fine. This made me think that perhaps the problem is that the ASP.NET application runs as NETWORK SERVICE while the Windows Forms application runs on a domain user account, but it turns out that I have another ASP.NET application sending e-mail through the same SMTP-server running under NETWORK SERVER at the same IIS, and this application does not experience this problem.
I've further tried to send e-mails through the SMTP-server manually by telnet the smtp-server on port 25 and running the SMTP-protocol manually, and it all works fine. The SMTP-server is not configured with any kind of authentication or SSL.
Another mysterious fact is that the ASP.NET application can send e-mails from an adress within the same domain to an e-mail adress within the same domain, but not to any adress outside of the domain. But the Windows Forms application, that uses the exact same code, can send e-mails from any adress to any adress both within AND outside of the domain.
So to summarize:
The ASP.NET application can send
e-mails from addresses within the
domain to adresses within the domain,
but not to addresses outside of the
domain.
A Windows Forms application running
the same code on the same computer
can send e-mails from ANY address to
ANY address.
Another ASP.NET application on the
same IIS running under the same
account (NETWORK SERVICE) can send
e-mails using the same SMTP-server
from ANY adress to ANY adress.
There is no authentication configured
on the SMTP-Server.
Both the ASP.NET application and the
Windows Forms application utilizes
the System.Net.Mail.SmtpClient class
to send a
System.Net.Mail.MailMessage.
The code that sends the e-mail massage is:
private void button1_Click(object sender, EventArgs e)
{
MailMessage mesasge = new MailMessage(txtFrom.Text, txtTo.Text, "Test mail", txtBody.Text);
SmtpClient client = new SmtpClient();
if (!(string.IsNullOrEmpty(txtUserName.Text))) //Is false since txtUserName.Text is empty
client.Credentials = new System.Net.NetworkCredential(txtUserName.Text, txtPassword.Text);
client.EnableSsl = false;
client.Host = txtServer.Text;
client.Port = 25;
try
{
client.Send(mesasge);
}
catch (Exception ex)
{
txtResponse.Text = ex.Message;
}
}
As far as I can understand, this should be a matter of configuration rather than coding issues.

we are experiencing big difficulties in the configuration of ASP.Net state service and II7. The service seems not working correctly because when the application pools recycles the applicatio loose the session.If we try the same configuration in IIS6 it works correcly.What is the correct way to configure the aspnet session state service in iis7?
View 2 RepliesWe have an ASP.NET application deployed on 2 Application servers with load balancer server. It is using INPROC state management. The ADO.NET connection pooling is enabled with 50 as minimum connections and 100 maximum connections.
In Load testing (using load testing tool) when the application reaches to 50 users no more users can connect (login) to application the TPS reaches zero. No errors are logged in application log related to application or database. The sessions are working fine.
Currently, on our production IIS web farm, we host about 15 applications in a single App Pool (Default App Pool). There are two websites and about 13 virtual directories.A colleague has recommended that we change our IIS configuration so each application is a separate App Pool (with identical settings).
Is there any drawback or potential issues to doing this?Is it possible that ASP.NET applications could have been built with the requirements that they are all within the same App Pool?
I know that ASP.NET MVC has error filter attribute to handle specified error type. However, this feature cannot catch any error that occurs when application start. Therefore, I need to add some code to "Application_Error" method for handling this error like the following code.
public void Application_Error(object sender, EventArgs e)
{// At this point we have information about the error
var ctx = HttpContext.Current;
var exception = ctx.Server.GetLastError();
[code]...
Apologies if this seems obvious, but after a week searching I can't find a clear answer to my problem.
I have developed an application in Visual Web Developer 2010 Express that uses the asp.net application services membership provider. It works well in development on my machine (data in the ASPNETDB.MDF database).
I packaged my application and deployed the relevant files with FTP to my shared hosting provider.
I took a copy of the ASPNETDB.MDF and restored it to the SQL Server 2008 on my shared hosting. I can connect to this through the Database Explorer in Visual Web Developer, but it doesn't contain any schema or data.
I know once I have the database in production I will have to make sure the connection string in web.config is poiting to it, but I don't know how to get the DB to production in the first place.
I need to develop an application, which will get records (orders) from one application and process them. The updates to this records (order updates) will be sent back to the source application for end customer reference. I'm planning to achieve this data synchronization at the database level using triggers and stored procedures to insert database between the 2 databases.
But, the issue is I have to deploy this application in 3 different customer sites and I have to change the database names (cannot use the same database name) in each deployment manually. Because of this deployment issue, I was thinking of handling this within the asp.net application where I can store the db name in the database and then build the query within the application, but I dont want to do it as building queries like that doesnt look very professional.

View 1 RepliesWe have an ASP.NET 3.5 Web application in which we have faced the below issue:
The application is working fine but suddently at one point application URL prompts for the authentication. When we (the support team) checked the server, we were able to identify that the access was denied for some of the main files (like web.config, default page). When we enabled the access the application started working fine.
