  • Book Review: &ldquo;Inside Microsoft SQL Server 2008: T-SQL Querying&rdquo; by Itzik Ben-Gan et al

    - by Sam Abraham
    In the past few weeks, I have been reading “Inside Microsoft SQL Server 2008: T-SQL Querying” by Itzik Ben-Gan et al. In the next few lines, I will be providing a quick book review having finished reading this valuable resource on SQL Server 2008. In this book, the authors have targeted most of the common as well as advanced T-SQL Querying scenarios that one would use for development on a SQL Server database. Book content covered sufficient theory and practice to empower its readers to systematically write better performance-tuned queries. Chapter one introduced a quick refresher of the basics of query processing. Chapters 2 and 3 followed with a thorough coverage of applicable relational algebra concepts which set a good stage for chapter 4 to dive deep into query tuning. Chapter 4 has been my favorite chapter of the book as it provided nice illustrations of the internals of indexes, waits, statistics and query plans. I particularly appreciated the thorough explanation of execution plans which helped clarify some areas I may have not paid particular attention to in the past. The book continues to focus on SQL operators tackling a few in each chapter and covering their internal workings and the best practices to follow when used. Figures and illustrations have been particularly helpful in grasping advanced concepts covered therein. In conclusion, Inside Microsoft SQL Server 2008: T-SQL Querying provided me with 750+ pages of focused, advanced and practical knowledge that has added a few tips and tricks to my arsenal of query tuning strategies. Many thanks to the O’Reilly User Group Program and its support of our West Palm Beach Developers’ Group. --Sam Abraham

  • Az Oracle üzleti intelligencia csomag Windows Server 2008-on is, a kliens Vista op.rsz-en is

    - by Fekete Zoltán
    Tegnap az Oracle BI Hands On rendezvényen felmerült a kérdés, hogy az Oracle Business Intelligence Enterprise Editon fut-e Windows Server 2008-on. A válasz: IGEN. Az Oracle BI EE fut a Windows Server 2008-on. Emellett a másik kérdésre a válasz: IGEN, a kliens lehet Windows Vista is. Mivel az Oracle BI szerver szoftver, amit egy böngészovel érnek el a felhasználók elemzési, lekérdezés/jelentés/riport- készítési feladatok elvégzésére, ezért az Oracle BI csak szerver operációs rendszerekre van bevizsgálva: Linux, Solaris, HP-UX, AIX és Windows platformokon. A jelenleg támogatott operációs rendszerek: Microsoft Windows 2000/2003 Server; Microsoft Windows Server 2008 Enterprise Edition x86 32 bit2 - Red Hat Enterprise Linux AS 4.x; Red Hat Enterprise Linux Server/Advanced Platform 5 - Novell SUSE 9.x - Oracle Enterprise Linux 4; Oracle Enterprise Linux 5 - Sun Solaris 9 SPARC 32 bit ; Sun Solaris 9 SPARC 64 bit; Sun Solaris 10 SPARC 32 bit; Sun Solaris 10 SPARC 64 bit - AIX 5.2 PowerPC 32 bit; AIX 5.2 PowerPC 64 bit; AIX 5.3 PowerPC 32 bit; AIX 5.3 PowerPC 64 bit; AIX 6.1 PowerPC 32 bit; AIX 6.1 PowerPC 64 bit - HP-UX 11.11 PA-RISC 64 bit; HP-UX 11.23 PA-RISC 64 bit; HP-UX 11.23 Itanium 64 bit; HP-UX 11.31 Itanium 64 bit A böngészos hozzáférést az irányítópultokhoz (dashboard), interaktív elemzo munkához használható operációs rendszerek: Windows, Vista, Linux, Solaris, Apple Mac OS 10.x.

  • SQL 2008/2005 Hosting :: Error - “Named Pipes Provider, error: 40 – Could not open a connection to SQL Server”

    - by mbridge
    When setting up a Microsoft Windows Server 2008 system, I went through the motions to set up IIS, MS SQL Server 2008, and Visual Studio 2010 to use as a test-bed. One of the immediate benefits of setting up such a system is that most development can be done remotely: MS SQL Server Management Studio, Visual Studio’s Web development suite, as well as file shares, remote desktop, etc, make for a great way to remotely develop in ‘pristine’ conditions. But there are drawbacks, too, such as needing to deal with firewall issues, not being able to penetrate past a router or the requirement of setting up a VPN. One of the problems I encountered when trying to remote into the MS SQL Server 2008 that I’d set up was the following error: Named Pipes Provider, error: 40 – Could not open a connection to SQL Server I followed the below steps, and was able to connect to the server after just a few moments of tinkering: 1. From the server in question, surf to this Microsoft article, and download and install the Firewall rules modification program. Never drop your firewall, even on a development machine, unless you have a really good reason to. 2. Launch SQL Server Configuration Manager. Navigate to SQL Server Network Configuration, then Protocols for your server name. Enable TCP/IP and Named Pipes by right-clicking and choosing Enable for each given Protocol Name. 3. Restart the SQL Server service from Services (or from command line, subsequently run “net stop mssqlserver” then “net start mssqlserver”. 4. Try your remote connection once more, and you should be able to connect. It’s not a terribly difficult concept, but one of the more challenging tasks developers face is dealing with environment setup. And while there is a certain blurred-line overlap between software development and server administration, sometimes the latter is daunting, especially given that you might set up only a handful of servers during your career.

Do I need to have the Year and Month column or can Excel automatically determine this? Current chart:

    I am trying to remote debug a Windows Form app with VS2008. Attaching to process works fine (Remote (Native only with no authentication)), but when I open the modules window and try to load symbols I get No native symbols in symbol file. I realise it has something to do with how the app was build but cannot figure out what ?

  • XamlParseException due to DatePicker from WPFToolKit

I keep getting the following exception. I am getting the exception when I run the application exe from the Release folder. I do not get the exception at all when normally debugging the application in Visual Studio. I have worked out that the exception is because of a DatePicker control I am using - as if I remove the control (build and run the release exe again) the exception goes away. How on earth could I work out what is going wrong here? The datepicker looks so much better but for the effort this looks like it might be to fix I may be incline to switch for a textbox which I validate when the submit button is pressed! Dissapointing...

PlaygroundEntities context = new PlaygroundEntities(); Person p = new Person { Status = PersonStatus.Alive, BirthDate = new DateTime(1982,3,18), Name = "Joe Smith" }; context.AddToPeople(p); context.SaveChanges(); When i run this code i get the following error The conversion of a datetime2 data type to a datetime data type resulted in an out-of-range value.\r\nThe statement has been terminated.

    - by acidzombie24
    I have an error at Column 'key' in table 'misc_info' is of a type that is invalid for use as a key column in an index. where key is a nvarchar(max). A quick google found this. It however doesnt explain what a solution is. How do i create something like Dictionary where the key and value are both strings and obviously the key must be unique and is single. My sql statement was create table [misc_info] ( [id] INTEGER PRIMARY KEY IDENTITY NOT NULL, [key] nvarchar(max) UNIQUE NOT NULL, [value] nvarchar(max) NOT NULL);

  • C# - null vs "Could not evaluate expression"

    I have code like this: private Box mCurBox; public Box CurBox { get { return mCurBox; } set { if (mCurBox != value) { mCurBox = value; } } } When mCurBox is null then CurBox the debugger says "Could not be evaluated". If it knows that the value underneath is null then how come it can't figure it out?

  • MSVC Compiler options with mojo-native in Maven

    - by graham.reeds
    I'm trying to set up a test environment with Maven to build VC++ and I am way behind on this. I have 3 source files that I builds a dll (once I get this fixed it should be a simple matter to add the unit-tests): hook.cpp hook.h hook.def This is compiled, on the command line, with the following: C:\Develop\hook\src\main\msvc>cl -o hook.dll Hook.cpp /D HOOK_DLLEXPORT /link /DLL /DEF:"Hook.def" Which produces the expected obj, dll, lib and exp files. So now to get this working in Maven2 with the Mojo-native plugin. With no options Maven w/Mojo gives me this (truncated) output: [INFO] [native:initialize {execution: default-initialize}] [INFO] [native:unzipinc {execution: default-unzipinc}] [INFO] [native:javah {execution: default-javah}] [INFO] [native:compile {execution: default-compile}] [INFO] cmd.exe /X /C "cl -IC:\Develop\hook\src\main\msvc /FoC:\Develop\hook\targ et\objs\Hook.obj -c C:\Develop\hook\src\main\msvc\Hook.cpp" Microsoft (R) 32-bit C/C++ Optimizing Compiler Version 15.00.30729.01 for 80x86 Copyright (C) Microsoft Corporation.

  • DataView.RowFilter Vs DataTable.Select() vs DataTable.Rows.Find()

    - by Aseem Gautam
    Considering the code below: Dataview someView = new DataView(sometable) someView.RowFilter = someFilter; if(someView.count > 0) { …. } Quite a number of articles which say Datatable.Select() is better than using DataViews, but these are prior to VS2008. Solved: The Mystery of DataView's Poor Performance with Large Recordsets Array of DataRecord vs. DataView: A Dramatic Difference in Performance Googling on this topic I found some articles/forum topics which mention Datatable.Select() itself is quite buggy(not sure on this) and underperforms in various scenarios. On this(Best Practices ADO.NET) topic on msdn it is suggested that if there is primary key defined on a datatable the findrows() or find() methods should be used insted of Datatable.Select(). This article here (.NET 1.1) benchmarks all the three approaches plus a couple more. But this is for version 1.1 so not sure if these are valid still now. Accroding to this DataRowCollection.Find() outperforms all approaches and Datatable.Select() outperforms DataView.RowFilter. So I am quite confused on what might be the best approach on finding rows in a datatable. Or there is no single good way to do this, multiple solutions exist depending upon the scenario?

It's only happening on this server, on any of the app pools on the server (not confined to this one) and an app pool restart sorts it. Any help much appreciated. Cheers, Matthew

  • "There were build errors. Would you like to continue and run the last successful build?" not showing

    - by Kevin Wilson
    Hi, Not a massive problem but something that has been bugging the life out of me... One of my colleagues was trying out some code on my machine and got the "There were build errors. Would you like to continue and run the last successful build?" pop-up when the build failed on Visual Studio. He clicked on the "don't show this again" checkbox and closed the dialogue. My problem is that I can't get the dialogue to show up again. I found these instructions online: "Select Tools, Options, Projects and Solutions, Build and Run. Then set the option "On run, when build or deployment errors occur" to Prompt to Launch." but that doesn't work. Resetting the IDE settings to default don't make any difference either. Is there any way to get this dialogue back or has it gone forever? Thanks, K

  • How to Integrate ILMerge into Visual Studio Build Process to Merge Assemblies?

    - by AMissico
    I want to merge one .NET DLL assembly and one C# Class Library project referenced by a VB.NET Console Application project into one command-line console executable. I can do this with ILMerge from the command-line, but I want to integrate this merging of reference assemblies and projects into the Visual Studio project. From my reading, I understand that I can do this through a MSBuild Task or a Target and just add it to a C#/VB.NET Project file, but I can find no specific example since MSBuild is large topic. Moreover, I find some references that add the ILMerge command to the Post-build event. How do I integrate ILMerge into a Visual Studio (C#/VB.NET) project, which are just MSBuild projects, to merge all referenced assemblies (copy-local=true) into one assembly? How does this tie into a possible ILMerge.Targets file? Is it better to use the Post-build event?

  • Understanding RTF and edit it with vb.net

    - by Jacob Kofoed
    I have this RichTextbox in my vb.net form and I would like to when a user click a button, for example to embold the selected text, how would I do this. Also, I do NOT want to use the standard vb.net expressions such as RichTextBox1.SelectedText.Font.Bold = true. I want to do something like RichTextbox1.SelectedRTF="[bold]" & RichTextBox1.SelectedRTF & "[/bold]" or whatever RTF looks like. Can I just add the RTF options random places or can a RichTextBox return an error if the text is in wrong format. I'm mostly looking for info on how to work with RTF without using the standard vb expressions. Thank you very much for any help provided

  • How to add SQLite (SQLite.NET) to my C# project

    - by Lirik
    I followed the instructions in the documentation: Scenario 1: Version Independent (does not use the Global Assembly Cache) This method allows you to drop any new version of the System.Data.SQLite.DLL into your application's folder and use it without any code modifications or recompiling. Add the following code to your app.config file: <configuration> <system.data> <DbProviderFactories> <remove invariant="System.Data.SQLite"/> <add name="SQLite Data Provider" invariant="System.Data.SQLite" description=".Net Framework Data Provider for SQLite" type="System.Data.SQLite.SQLiteFactory, System.Data.SQLite" /> </DbProviderFactories> </system.data> </configuration> My app.config file now looks like this: <?xml version="1.0" encoding="utf-8" ?> <configuration> <configSections> <sectionGroup name="userSettings" type="System.Configuration.UserSettingsGroup, System, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" > <section name="DataFeed.DataFeedSettings" type="System.Configuration.ClientSettingsSection, System, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" allowExeDefinition="MachineToLocalUser" requirePermission="false" /> </sectionGroup> </configSections> <userSettings> <DataFeed.DataFeedSettings> <setting name="eodData" serializeAs="String"> <value>False</value> </setting> </DataFeed.DataFeedSettings> </userSettings> <system.data> <DbProviderFactories> <remove invariant="System.Data.SQLite"/> <add name="SQLite Data Provider" invariant="System.Data.SQLite" description=".Net Framework Data Provider for SQLite" type="System.Data.SQLite.SQLiteFactory, System.Data.SQLite" /> </DbProviderFactories> </system.data> </configuration> My project is called "DataFeed": using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Data.SQLite; //<-- Causes compiler error namespace DataFeed { class Program { static void Main(string[] args) { } } } The error I get is: .\dev\DataFeed\Program.cs(5,19): error CS0234: The type or namespace name 'SQLite' does not exist in the namespace 'System.Data' (are you missing an assembly reference?) I'm not using the GAC, I simply dropped the System.Data.SQLite.dll into my .\dev\DataFeed\ folder. I thought that all I needed to do is add the DLL to the project folder as it was mentioned in the documentation. Any hints on how to actually make this work?

  • TeamCity stopped working once I added NUnit to the mix

    - by Dave
    I'm struggling a lot trying to get our build server going. I am currently running tests in a Windows XP virtual machine, and have installed TeamCity v5.0.3, build 10821. I am using NUnit v2.5.3. I finished the initial setup with TeamCity without any issues at all, provided that I use the sln2008 build runner that makes the entire process almost brainless. It's really quite nice that way, and very satisfying to see your first successful automated build. Now it's time to kick it up a notch and I wanted to get NUnit working. I keep the NUnit 2.5.3 assemblies in an external libs folder in SVN, so I checked that out onto the test system. I selected NUnit 2.5.3 from the build runner options, as the online instructions had recommended. But when I build, I get the following error: Window1.xaml.cs(14,7): error CS0246: The type or namespace name ‘NUnit’ could not be found (are you missing a using directive or an assembly reference?) Window1.xaml.cs(28,10): error CS0246: The type or namespace name ‘Test’ could not be found (are you missing a using directive or an assembly reference?) Window1.xaml.cs(28,10): error CS0246: The type or namespace name ‘TestAttribute’ could not be found (are you missing a using directive or an assembly reference?) Everything compiles great in the IDE. From finding blog posts and submitting comments, I got some advice and confirmed the following: I have the HintPath value set properly in my project file (points to the external lib) I can also do a full Release and Debug build from the command line using msbuild I have tried do use the NUnit installer so nunit.framework.dll gets registered into the GAC I have changed the build agent's logon account to be a user on the test system, rather than LOCAL SYSTEM. Nothing seems to help... can anyone else here offer me some advice on what to try next?

  • Debugging unmanaged code while debugging managed code

    - by sc_ray
    Hi, The .NET 3.5 application I am working on consists of bunch of different solutions. Some of these solutions consist of managed code(C#) and others have unmanaged code(C++). Methods written in C# communicate with the ones written in C++. I am trying to trace the dependencies between these various functions and I thought setting breakpoints on the solution consisting my C++ functions. One of the C# solutions have the startup project. I run this solution in debug mode with the expectation that the breakpoints in my unmanaged code will be hit but nothing really happens. Can somebody guide me through the process of debugging mixed applications such as these using the Visual Studio IDE? Thanks

  • Consuming WebSphere service from WCF client: Unable to create AxisService from ServiceEndpointAddres

    - by JohnIdol
    I am consuming (or trying to consume) a WebSphere service from a WCF client (service reference + bindings generated through svcutil). Connection seems to be established successfully but I am getting the following error: CWWSS7200E: Unable to create AxisService from ServiceEndpointAddress [address] Rings any bell? I am guessing the request format is somehow being rejected by the service, I am sniffing it with fiddler and it looks fine overall (can post if ppl think it could help). Found this article, but it doesn't seem to apply to my case. Any help appreciated!
