  • Free eBook with SQL Server performance tips and nuggets

    - by Claire Brooking
    I’ve often found that the kind of tips that turn out to be helpful are the ones that encourage me to make a small step outside of a routine. No dramatic changes – just a quick suggestion that changes an approach. As a languages student at university, one of the best I spotted came from outside the lecture halls and ended up saving me time (and lots of huffing and puffing) – the use of a rainbow of sticky notes for well-used pages and letter categories in my dictionary. Simple, but armed with a heavy dictionary that could double up as a step stool, those markers were surprisingly handy. When the Simple-Talk editors told me about a book they were planning that would give a series of tips for developers on how to improve database performance, we all agreed it needed to contain a good range of pointers for big-hitter performance topics. But we wanted to include some of the smaller, time-saving nuggets too. We hope we’ve struck a good balance. The 45 Database Performance Tips eBook covers different tips to help you avoid code that saps performance, whether that’s the ‘gotchas’ to be aware of when using Object to Relational Mapping (ORM) tools, or what to be aware of for indexes, database design, and T-SQL. The eBook is also available to download with SQL Prompt from Red Gate. We often hear that it’s the productivity-boosting side of SQL Prompt that makes it useful for everyday coding. So when a member of the SQL Prompt team mentioned an idea to make the most of tab history, a new feature in SQL Prompt 6 for SQL Server Management Studio, we were intrigued. Now SQL Prompt can save tabs we have been working on in SSMS as a way to maintain an active template for queries we often recycle. When we need to reuse the same code again, we search for our saved tab (and we can also customize its name to speed up the search) to get started. We hope you find the eBook helpful, and as always on Simple-Talk, we’d love to hear from you too. If you have a performance tip for SQL Server you’d like to share, email Melanie on the Simple-Talk team ([email protected]) and we’ll publish a collection in a follow-up post.

  • Session and Pop Up Window

    - by imran_ku07
     Introduction :        Session is the secure state management. It allows the user to store their information in one page and access in another page. Also it is so much powerful that store any type of object. Every user's session is identified by their cookie, which client presents to server. But unfortunately when you open a new pop up window, this cookie is not post to server with request, due to which server is unable to identify the session data for current user.         In this Article i will show you how to handle this situation,  Description :         During working in a application, i was getting an Exception saying that Session is null, when a pop window opens. After seeing the problem more closely i found that ASP.NET_SessionId cookie for parent page is not post in cookie header of child (popup) window.         Therefore for making session present in both parent and child (popup) window, you have to present same cookie. For cookie sharing i passed parent SessionID in query string,   window.open('http://abc.com/s.aspx?SASID=" & Session.SessionID &','V');           and in Application_PostMapRequestHandler application Event, check if the current request has no ASP.NET_SessionId cookie and SASID query string is not null then add this cookie to Request before Session is acquired, so that Session data remain same for both parent and popup window.    Private Sub Application_PostMapRequestHandler(ByVal sender As Object, ByVal e As EventArgs)           If (Request.Cookies("ASP.NET_SessionId") Is Nothing) AndAlso (Request.QueryString("SASID") IsNot Nothing) Then               Request.Cookies.Add(New HttpCookie("ASP.NET_SessionId", Request.QueryString("SASID")))           End If       End Sub           Now access Session in your parent and child window without any problem. How this works :          ASP.NET (both Web Form or MVC) uses a cookie (ASP.NET_SessionId) to identify the user who is requesting. Cookies are may be persistent (saved permanently in user cookies ) or non-persistent (saved temporary in browser memory). ASP.NET_SessionId cookie saved as non-persistent. This means that if the user closes the browser, the cookie is immediately removed. This is a sensible step that ensures security. That's why ASP.NET unable to identify that the request is coming from the same user. Therefore every browser instance get it's own ASP.NET_SessionId. To resolve this you need to present the same parent ASP.NET_SessionId cookie to the server when open a popup window.           You can confirm this situation by using some tools like Firebug, Fiddler,  Summary :          Hopefully you will enjoy after reading this article, by seeing that how to workaround the problem of sharing Session between different browser instances by sharing their Session identifier Cookie.

  • WebClient error when using a thread in .NET

    - by Kiranu
    I'm having a very weird error using the WebClient class in .NET 4. The app simply downloads some files off the internet and provides output on a textbox (the GUI is WPF). The method that does this is the following: void DownloadFiles(object files) { fileL = (List<string>) files; foreach (string url in fileL) { byte[] data; using (System.Net.WebClient k = new WebClient()) { data = k.DownloadData(url); } //Bunch of irrelevant code goes here... } } (I added the using while trying to divine [yes I'm that desperate/ignorant] a solution, the problem happens even if the webclient is declared and initialized outside the foreach loop) Now the problem appears only when I'm executing this method on a thread separate from the WPF UI main thread. If it is executed on the UI thread then it works perfectly. When a new thread is created with: Thread t = new Thread(DownloadFiles); t.Start(files); The first time the code goes into the loop it will work, but when its the second pass inside the loop, I will always receive a TargetParameterCountException. I can't make any sense of this error. Any help is very much appreciated. EDIT Here are the Exception Details: Exception.Message = "Parameter count mismatch."

I know I need a form collection for this but I want to know if there is a built in form collection that holds all the forms in VB.NET or I need to implement my own. Thank you.
