  • Solaris X86 AESNI OpenSSL Engine

    - by danx
    Solaris X86 AESNI OpenSSL Engine Cryptography is a major component of secure e-commerce. Since cryptography is compute intensive and adds a significant load to applications, such as SSL web servers (https), crypto performance is an important factor. Providing accelerated crypto hardware greatly helps these applications and will help lead to a wider adoption of cryptography, and lower cost, in e-commerce and other applications. The Intel Westmere microprocessor has six new instructions to acclerate AES encryption. They are called "AESNI" for "AES New Instructions". These are unprivileged instructions, so no "root", other elevated access, or context switch is required to execute these instructions. These instructions are used in a new built-in OpenSSL 1.0 engine available in Solaris 11, the aesni engine. Previous Work Previously, AESNI instructions were introduced into the Solaris x86 kernel and libraries. That is, the "aes" kernel module (used by IPsec and other kernel modules) and the Solaris pkcs11 library (for user applications). These are available in Solaris 10 10/09 (update 8) and above, and Solaris 11. The work here is to add the aesni engine to OpenSSL. X86 AESNI Instructions Intel's Xeon 5600 is one of the processors that support AESNI. This processor is used in the Sun Fire X4170 M2 As mentioned above, six new instructions acclerate AES encryption in processor silicon. The new instructions are: aesenc performs one round of AES encryption. One encryption round is composed of these steps: substitute bytes, shift rows, mix columns, and xor the round key. aesenclast performs the final encryption round, which is the same as above, except omitting the mix columns (which is only needed for the next encryption round). aesdec performs one round of AES decryption aesdeclast performs the final AES decryption round aeskeygenassist Helps expand the user-provided key into a "key schedule" of keys, one per round aesimc performs an "inverse mixed columns" operation to convert the encryption key schedule into a decryption key schedule pclmulqdq Not a AESNI instruction, but performs "carryless multiply" operations to acclerate AES GCM mode. Since the AESNI instructions are implemented in hardware, they take a constant number of cycles and are not vulnerable to side-channel timing attacks that attempt to discern some bits of data from the time taken to encrypt or decrypt the data. Solaris x86 and OpenSSL Software Optimizations Having X86 AESNI hardware crypto instructions is all well and good, but how do we access it? The software is available with Solaris 11 and is used automatically if you are running Solaris x86 on a AESNI-capable processor. AESNI is used internally in the kernel through kernel crypto modules and is available in user space through the PKCS#11 library. For OpenSSL on Solaris 11, AESNI crypto is available directly with a new built-in OpenSSL 1.0 engine, called the "aesni engine." This is in lieu of the extra overhead of going through the Solaris OpenSSL pkcs11 engine, which accesses Solaris crypto and digest operations. Instead, AESNI assembly is included directly in the new aesni engine. Instead of including the aesni engine in a separate library in /lib/openssl/engines/, the aesni engine is "built-in", meaning it is included directly in OpenSSL's libcrypto.so.1.0.0 library. This reduces overhead and the need to manually specify the aesni engine. Since the engine is built-in (that is, in libcrypto.so.1.0.0), the openssl -engine command line flag or API call is not needed to access the engine—the aesni engine is used automatically on AESNI hardware. Ciphers and Digests supported by OpenSSL aesni engine The Openssl aesni engine auto-detects if it's running on AESNI hardware and uses AESNI encryption instructions for these ciphers: AES-128-CBC, AES-192-CBC, AES-256-CBC, AES-128-CFB128, AES-192-CFB128, AES-256-CFB128, AES-128-CTR, AES-192-CTR, AES-256-CTR, AES-128-ECB, AES-192-ECB, AES-256-ECB, AES-128-OFB, AES-192-OFB, and AES-256-OFB. Implementation of the OpenSSL aesni engine The AESNI assembly language routines are not a part of the regular Openssl 1.0.0 release. AESNI is a part of the "HEAD" ("development" or "unstable") branch of OpenSSL, for future release. But AESNI is also available as a separate patch provided by Intel to the OpenSSL project for OpenSSL 1.0.0. A minimal amount of "glue" code in the aesni engine works between the OpenSSL libcrypto.so.1.0.0 library and the assembly functions. The aesni engine code is separate from the base OpenSSL code and requires patching only a few source files to use it. That means OpenSSL can be more easily updated to future versions without losing the performance from the built-in aesni engine. OpenSSL aesni engine Performance Here's some graphs of aesni engine performance I measured by running openssl speed -evp $algorithm where $algorithm is aes-128-cbc, aes-192-cbc, and aes-256-cbc. These are using the 64-bit version of openssl on the same AESNI hardware, a Sun Fire X4170 M2 with a Intel Xeon E5620 @2.40GHz, running Solaris 11 FCS. "Before" is openssl without the aesni engine and "after" is openssl with the aesni engine. The numbers are MBytes/second. OpenSSL aesni engine performance on Sun Fire X4170 M2 (Xeon E5620 @2.40GHz) (Higher is better; "before"=OpenSSL on AESNI without AESNI engine software, "after"=OpenSSL AESNI engine) As you can see the speedup is dramatic for all 3 key lengths and for data sizes from 16 bytes to 8 Kbytes—AESNI is about 7.5-8x faster over hand-coded amd64 assembly (without aesni instructions). Verifying the OpenSSL aesni engine is present The easiest way to determine if you are running the aesni engine is to type "openssl engine" on the command line. No configuration, API, or command line options are needed to use the OpenSSL aesni engine. If you are running on Intel AESNI hardware with Solaris 11 FCS, you'll see this output indicating you are using the aesni engine: intel-westmere $ openssl engine (aesni) Intel AES-NI engine (no-aesni) (dynamic) Dynamic engine loading support (pkcs11) PKCS #11 engine support If you are running on Intel without AESNI hardware you'll see this output indicating the hardware can't support the aesni engine: intel-nehalem $ openssl engine (aesni) Intel AES-NI engine (no-aesni) (dynamic) Dynamic engine loading support (pkcs11) PKCS #11 engine support For Solaris on SPARC or older Solaris OpenSSL software, you won't see any aesni engine line at all. Third-party OpenSSL software (built yourself or from outside Oracle) will not have the aesni engine either. Solaris 11 FCS comes with OpenSSL version 1.0.0e. The output of typing "openssl version" should be "OpenSSL 1.0.0e 6 Sep 2011". 64- and 32-bit OpenSSL OpenSSL comes in both 32- and 64-bit binaries. 64-bit executable is now the default, at /usr/bin/openssl, and OpenSSL 64-bit libraries at /lib/amd64/libcrypto.so.1.0.0 and libssl.so.1.0.0 The 32-bit executable is at /usr/bin/i86/openssl and the libraries are at /lib/libcrytpo.so.1.0.0 and libssl.so.1.0.0. Availability The OpenSSL AESNI engine is available in Solaris 11 x86 for both the 64- and 32-bit versions of OpenSSL. It is not available with Solaris 10. You must have a processor that supports AESNI instructions, otherwise OpenSSL will fallback to the older, slower AES implementation without AESNI. Processors that support AESNI include most Westmere and Sandy Bridge class processor architectures. Some low-end processors (such as for mobile/laptop platforms) do not support AESNI. The easiest way to determine if the processor supports AESNI is with the isainfo -v command—look for "amd64" and "aes" in the output: $ isainfo -v 64-bit amd64 applications pclmulqdq aes sse4.2 sse4.1 ssse3 popcnt tscp ahf cx16 sse3 sse2 sse fxsr mmx cmov amd_sysc cx8 tsc fpu Conclusion The Solaris 11 OpenSSL aesni engine provides easy access to powerful Intel AESNI hardware cryptography, in addition to Solaris userland PKCS#11 libraries and Solaris crypto kernel modules.

  • Visual Studio 2010 Service Pack 1, now available for download

    - by Harish Ranganathan
    Visual Studio 2010 Service Pack 1 (SP1) is now available for general download for almost a week now.  The Beta of SP1 came couple of months back and it did a lot of performance enhancements, added support for HTML5 tags and few other stuff related to web development.  Now, the final release of SP1 is available.  The good part is that, if you had installed the SP1 beta, you don’t have to remove the Beta and start all over again.  You can apply the final release on top of the Beta and it works like a charm. So, in simplified terms, what is new in Visual Studio 2010 SP1 Before I start listing it down, I was checking if there was an MSDN article available on this and found http://msdn.microsoft.com/en-us/library/gg442059.aspx  While it reads (Beta), the same holds good for the release candidate as well.  Unlike VS 2008 SP1 and .NET 3.5 SP1 (which came together), this release doesn’t add any new project templates/item templates. However, there are lot of enhancements related to Web Deployment, Debugging and Unit Testing for .NET 3.5 applications. So, how does one find if you are running the correct version of SP1 final release. While the SP1 Beta (Help – About Visual Studio) reads Microsoft Visual Studio 2010 Version 10.0.3118.1 SP1 Rel, once you install the SP1 RTM release, it should read as below The download link for SP1 Beta is here Cheers!!!

  • A message to Denis Pitcher

    - by guybarrette
    Denis Pitcher, You posted this comment on my blog and some other blogs: Devteach's promotion for a one year MSDN subscription was not honoured and attempts to contact them result in a "we sent attendee info to MS, it's not our problem" response while attempts to contact Microsoft result in the suggestion that any queries should be redirect to Devteach. Hopefully not all attendees we're cheated though if you're considering attending a future Devteach it is recommended that you don't hold any expectation that they'll honour their promotions. I spoke to Jean-René Roy, DevTeach organizer and also to MSDN Canada folks.  Looks like the email you used to register for the conference is now bouncing (maybe a typo when you registered?).  That why you haven’t received any news about the offer.  The fact that you’re leaving the same comment on various blogs without your email address doesn’t help at all.  Thay want to contact you!  Also, looks like they never received your emails, maybe you used a the wrong email addresses. Anyway, please contact Jean-René Roy at [email protected] ASAP.

  • VSDB to SSDT part 3 : command-line deployment with SqlPackage.exe, replacement for Vsdbcmd.exe

    - by Etienne Giust
    For our continuous integration needs, we use a powershell script to handle deployment. A simpler approach would be to have a deployment task embedded within the build process. See the solution provided here by Jakob Ehn (a most interesting read which also dives into the '”deploying from Visual Studio” specifics) : http://geekswithblogs.net/jakob/archive/2012/04/25/deploying-ssdt-projects-with-tfs-build.aspx   For our needs, though, clearly separating our build phase from our deployment phase is important. It allows us to instantly deploy old versions. Also it is more convenient for continuous integration. So we stick with the powershell script approach. With VSDB projects, that script used to call the following command (the vsdbcmd executable was locally available, along with needed libraries): vsdbcmd.exe /a:Deploy /dd /cs:<CONNECTIONSTRING TO TARGET DB> /dsp:SQL /manifest:< PATH TO .deploymanifest FILE>   To be able to do the approximately same thing with a SSDT produced file (dacpac), you would call this command on a machine which has VS2012 installed (or the SSDT installed, see here : http://msdn.microsoft.com/en-us/library/hh500335%28v=vs.103%29):   C:\Program Files (x86)\Microsoft SQL Server\110\DAC\bin\SqlPackage.exe /Action:Publish /SourceFile:<PATH TO Database.dacpac FILE> /Profile:<PATH TO .publish.xml FILE>   And from within a powershell script :   & "C:\Program Files (x86)\Microsoft SQL Server\110\DAC\bin\SqlPackage.exe" /Action:Publish /SourceFile:<PATH TO Database.dacpac FILE> /Profile:<PATH TO .publish.xml FILE>   The command will consume a publish.xml file where the connection string and the deployment options are specified. You must be familiar with it if you have done some deployments from visual studio. If not, please refer to the above mentioned article by Jakob Ehn.   It is also possible to pass those parameters in the command line. The complete SqlPackage.exe syntax is detailed here : http://msdn.microsoft.com/en-us/library/hh550080%28v=vs.103%29.aspx

  • Adding and accessing custom sections in your C# App.config

    - by deadlydog
    So I recently thought I’d try using the app.config file to specify some data for my application (such as URLs) rather than hard-coding it into my app, which would require a recompile and redeploy of my app if one of our URLs changed.  By using the app.config it allows a user to just open up the .config file that sits beside their .exe file and edit the URLs right there and then re-run the app; no recompiling, no redeployment necessary. I spent a good few hours fighting with the app.config and looking at examples on Google before I was able to get things to work properly.  Most of the examples I found showed you how to pull a value from the app.config if you knew the specific key of the element you wanted to retrieve, but it took me a while to find a way to simply loop through all elements in a section, so I thought I would share my solutions here.   Simple and Easy The easiest way to use the app.config is to use the built-in types, such as NameValueSectionHandler.  For example, if we just wanted to add a list of database server urls to use in my app, we could do this in the app.config file like so: 1: <?xml version="1.0" encoding="utf-8" ?> 2: <configuration> 3: <configSections> 4: <section name="ConnectionManagerDatabaseServers" type="System.Configuration.NameValueSectionHandler" /> 5: </configSections> 6: <startup> 7: <supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.5" /> 8: </startup> 9: <ConnectionManagerDatabaseServers> 10: <add key="localhost" value="localhost" /> 11: <add key="Dev" value="Dev.MyDomain.local" /> 12: <add key="Test" value="Test.MyDomain.local" /> 13: <add key="Live" value="Prod.MyDomain.com" /> 14: </ConnectionManagerDatabaseServers> 15: </configuration>   And then you can access these values in code like so: 1: string devUrl = string.Empty; 2: var connectionManagerDatabaseServers = ConfigurationManager.GetSection("ConnectionManagerDatabaseServers") as NameValueCollection; 3: if (connectionManagerDatabaseServers != null) 4: { 5: devUrl = connectionManagerDatabaseServers["Dev"].ToString(); 6: }   Sometimes though you don’t know what the keys are going to be and you just want to grab all of the values in that ConnectionManagerDatabaseServers section.  In that case you can get them all like this: 1: // Grab the Environments listed in the App.config and add them to our list. 2: var connectionManagerDatabaseServers = ConfigurationManager.GetSection("ConnectionManagerDatabaseServers") as NameValueCollection; 3: if (connectionManagerDatabaseServers != null) 4: { 5: foreach (var serverKey in connectionManagerDatabaseServers.AllKeys) 6: { 7: string serverValue = connectionManagerDatabaseServers.GetValues(serverKey).FirstOrDefault(); 8: AddDatabaseServer(serverValue); 9: } 10: }   And here we just assume that the AddDatabaseServer() function adds the given string to some list of strings.  So this works great, but what about when we want to bring in more values than just a single string (or technically you could use this to bring in 2 strings, where the “key” could be the other string you want to store; for example, we could have stored the value of the Key as the user-friendly name of the url).   More Advanced (and more complicated) So if you want to bring in more information than a string or two per object in the section, then you can no longer simply use the built-in System.Configuration.NameValueSectionHandler type provided for us.  Instead you have to build your own types.  Here let’s assume that we again want to configure a set of addresses (i.e. urls), but we want to specify some extra info with them, such as the user-friendly name, if they require SSL or not, and a list of security groups that are allowed to save changes made to these endpoints. So let’s start by looking at the app.config: 1: <?xml version="1.0" encoding="utf-8" ?> 2: <configuration> 3: <configSections> 4: <section name="ConnectionManagerDataSection" type="ConnectionManagerUpdater.Data.Configuration.ConnectionManagerDataSection, ConnectionManagerUpdater" /> 5: </configSections> 6: <startup> 7: <supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.5" /> 8: </startup> 9: <ConnectionManagerDataSection> 10: <ConnectionManagerEndpoints> 11: <add name="Development" address="Dev.MyDomain.local" useSSL="false" /> 12: <add name="Test" address="Test.MyDomain.local" useSSL="true" /> 13: <add name="Live" address="Prod.MyDomain.com" useSSL="true" securityGroupsAllowedToSaveChanges="ConnectionManagerUsers" /> 14: </ConnectionManagerEndpoints> 15: </ConnectionManagerDataSection> 16: </configuration>   The first thing to notice here is that my section is now using the type “ConnectionManagerUpdater.Data.Configuration.ConnectionManagerDataSection” (the fully qualified path to my new class I created) “, ConnectionManagerUpdater” (the name of the assembly my new class is in).  Next, you will also notice an extra layer down in the <ConnectionManagerDataSection> which is the <ConnectionManagerEndpoints> element.  This is a new collection class that I created to hold each of the Endpoint entries that are defined.  Let’s look at that code now: 1: using System; 2: using System.Collections.Generic; 3: using System.Configuration; 4: using System.Linq; 5: using System.Text; 6: using System.Threading.Tasks; 7:  8: namespace ConnectionManagerUpdater.Data.Configuration 9: { 10: public class ConnectionManagerDataSection : ConfigurationSection 11: { 12: /// <summary> 13: /// The name of this section in the app.config. 14: /// </summary> 15: public const string SectionName = "ConnectionManagerDataSection"; 16: 17: private const string EndpointCollectionName = "ConnectionManagerEndpoints"; 18:  19: [ConfigurationProperty(EndpointCollectionName)] 20: [ConfigurationCollection(typeof(ConnectionManagerEndpointsCollection), AddItemName = "add")] 21: public ConnectionManagerEndpointsCollection ConnectionManagerEndpoints { get { return (ConnectionManagerEndpointsCollection)base[EndpointCollectionName]; } } 22: } 23:  24: public class ConnectionManagerEndpointsCollection : ConfigurationElementCollection 25: { 26: protected override ConfigurationElement CreateNewElement() 27: { 28: return new ConnectionManagerEndpointElement(); 29: } 30: 31: protected override object GetElementKey(ConfigurationElement element) 32: { 33: return ((ConnectionManagerEndpointElement)element).Name; 34: } 35: } 36: 37: public class ConnectionManagerEndpointElement : ConfigurationElement 38: { 39: [ConfigurationProperty("name", IsRequired = true)] 40: public string Name 41: { 42: get { return (string)this["name"]; } 43: set { this["name"] = value; } 44: } 45: 46: [ConfigurationProperty("address", IsRequired = true)] 47: public string Address 48: { 49: get { return (string)this["address"]; } 50: set { this["address"] = value; } 51: } 52: 53: [ConfigurationProperty("useSSL", IsRequired = false, DefaultValue = false)] 54: public bool UseSSL 55: { 56: get { return (bool)this["useSSL"]; } 57: set { this["useSSL"] = value; } 58: } 59: 60: [ConfigurationProperty("securityGroupsAllowedToSaveChanges", IsRequired = false)] 61: public string SecurityGroupsAllowedToSaveChanges 62: { 63: get { return (string)this["securityGroupsAllowedToSaveChanges"]; } 64: set { this["securityGroupsAllowedToSaveChanges"] = value; } 65: } 66: } 67: }   So here the first class we declare is the one that appears in the <configSections> element of the app.config.  It is ConnectionManagerDataSection and it inherits from the necessary System.Configuration.ConfigurationSection class.  This class just has one property (other than the expected section name), that basically just says I have a Collection property, which is actually a ConnectionManagerEndpointsCollection, which is the next class defined.  The ConnectionManagerEndpointsCollection class inherits from ConfigurationElementCollection and overrides the requied fields.  The first tells it what type of Element to create when adding a new one (in our case a ConnectionManagerEndpointElement), and a function specifying what property on our ConnectionManagerEndpointElement class is the unique key, which I’ve specified to be the Name field. The last class defined is the actual meat of our elements.  It inherits from ConfigurationElement and specifies the properties of the element (which can then be set in the xml of the App.config).  The “ConfigurationProperty” attribute on each of the properties tells what we expect the name of the property to correspond to in each element in the app.config, as well as some additional information such as if that property is required and what it’s default value should be. Finally, the code to actually access these values would look like this: 1: // Grab the Environments listed in the App.config and add them to our list. 2: var connectionManagerDataSection = ConfigurationManager.GetSection(ConnectionManagerDataSection.SectionName) as ConnectionManagerDataSection; 3: if (connectionManagerDataSection != null) 4: { 5: foreach (ConnectionManagerEndpointElement endpointElement in connectionManagerDataSection.ConnectionManagerEndpoints) 6: { 7: var endpoint = new ConnectionManagerEndpoint() { Name = endpointElement.Name, ServerInfo = new ConnectionManagerServerInfo() { Address = endpointElement.Address, UseSSL = endpointElement.UseSSL, SecurityGroupsAllowedToSaveChanges = endpointElement.SecurityGroupsAllowedToSaveChanges.Split(',').Where(e => !string.IsNullOrWhiteSpace(e)).ToList() } }; 8: AddEndpoint(endpoint); 9: } 10: } This looks very similar to what we had before in the “simple” example.  The main points of interest are that we cast the section as ConnectionManagerDataSection (which is the class we defined for our section) and then iterate over the endpoints collection using the ConnectionManagerEndpoints property we created in the ConnectionManagerDataSection class.   Also, some other helpful resources around using app.config that I found (and for parts that I didn’t really explain in this article) are: How do you use sections in C# 4.0 app.config? (Stack Overflow) <== Shows how to use Section Groups as well, which is something that I did not cover here, but might be of interest to you. How to: Create Custom Configuration Sections Using Configuration Section (MSDN) ConfigurationSection Class (MSDN) ConfigurationCollectionAttribute Class (MSDN) ConfigurationElementCollection Class (MSDN)   I hope you find this helpful.  Feel free to leave a comment.  Happy Coding!

  • Start Debugging in Visual Studio

    Every developer is familiar with hitting F5 and debugging their application, which starts their app with the Visual Studio debugger attached from the start (instead of attaching later). This is one way to achieve step 1 of the Live Debugging process. Hitting F5, F11, Ctrl+F10 and the other ways to start the process under the debugger is covered in this MSDN "How To". The way you configure the debugging experience, before you hit F5, is by selecting the "Project" and then the "Properties" menu (Alt+F7 on my keyboard bindings). Dependent on your project type there are different options, but if you browse to the Debug (or Debugging) node in the properties page you'll have a way to select local or remote machine debugging, what debug engines to use, command line arguments to use during debugging etc. Currently the .NET and C++ project systems are different, but one would hope that one day they would be unified to use the same mechanism and UI (I don't work on that product team so I have no knowledge of whether that is a goal or if it will ever happen). Personally I like the C++ one better, here is what it looks like (and it is described on this MSDN page): If you were following along in the "Attach to Process" blog post, the equivalent to the "Select Code Type" dialog is the "Debugger Type" dropdown: that is how you change the debug engine. Some of the debugger properties options appear on the standard toolbar in VS. With Visual Studio 11, the Debug Type option has been added to the toolbar If you don't see that in your installation, customize the toolbar to show it - VS 11 tends to be conservative in what you see by default, especially for the non-C++ Visual Studio profiles. Comments about this post by Daniel Moth welcome at the original blog.

  • Hot fix published for TFS2010 upgrade issues

    - by jehan
    Microsoft has released a hot fix for the issues that are identified after the migration of TFS2005/TFS2008 servers to TFS2010. The issues are related to Merging and Labels: ·         Labels that were created before the upgrade are entirely empty.  Labels could be also have incorrect contents. ·         The merge wizard in Visual Studio does not display all valid merge targets for a given source path/branch. ·         During merging, merge candidates are shown for changes that were already merged prior to the upgrade. If you have not yet upgraded to TFS 2010, the hotfix is now available and is highly recommended to be applied before configuring your team project collections. Because this hotfix applies to the upgrade of version control content, it must be applied after TFS 2010 setup is complete, but before configuration is started.  At the end of the setup experience, the Success screen is shown indicating the completion of the installation.  Normally, users will continue on to the configuration part, but in this case, the user need to cancel the configuration part by un-checking the “Launch Team Foundation Server Configuration Tool” box, which will enable the Cancel button. After exiting setup, the hotfix executable can be run to update the upgrade steps. Once the hotfix is installed, the TFS Configuration Wizard will need to be re-launched from the Start Menu to complete the upgrade process.    The hotfix has been published on MSDN Code Gallery – you can find it here: http://code.msdn.microsoft.com/KB2135068   If you have upgraded to TFS2010 and facing any of the above issues, then checkout this KB for Resolution: http://support.microsoft.com/kb/2193796/en-us

  • Visual Studio 2010 Is Here!

    - by Bill Evjen
    I think back to the days of the first versions of Visual Studio (when it was called Visual Studio .NET, remember?) and I think about how far Microsoft has come with this IDE. It really is the best IDE on the market. There is so much to this IDE it is amazing. It now can really handle managing your complete software application development lifecycle. For me, it is (besides Windows 7) the best and most successful product Microsoft has developed. You can obviously get this now and it is available on MSDN and some other places: MSDN Visual Studio Trial Editions Visual Studio 2010 Express Editions (free) You will also find great info at the Visual Studio Developer Center. Some other interesting tidbits of info: JetBrain’s ReSharper 5.0 has been released for VS2010 Oracle will have the new Oracle Dev Tools for VS2010 within one month - http://bit.ly/9gC9NE Visual Studio 64-bit - Why there is no 64-bit version of VS - http://bit.ly/dhhwAj In installing this version of Visual Studio, if you have been working on the previous RC builds, then you are going to want to uninstall these previous editions of the 2010 product. You can do this through the Add Remove Programs dialog and you are going to want to select the appropriate item from the long list of Visual Studio items. You are then going to want to step through the Visual Studio dialog (it will seem as if you are installing it again) – and you will then come to a point where you can select the option to Uninstall the entire application. If you have installed the Silverlight 4 RC stuff, then you are also going to want to uninstall this and you are also going to want to uninstall the “Update for Visual Studio 2010 (KB976272)” before installing Silverlight RC2 – which you can find on www.silverlight.net.

  • Windows CE and the Compact Framework are dead?

    - by Valter Minute
    This is one of the question that I’ve been asked more and more frequently at my public speeches and each time I meet customers. The announcement of the new Windows Phone 7 platform and the release of Visual Studio 2010 generated a bit of confusion around Windows CE and some of the technologies it supports. Windows CE is still alive and a lot of good programmers are working on the new releases (I had a chance to know some of them during the MVP summit in February). Here’s a blog post from Olivier Bloch that describes the situation and provides some good news about the OS: http://blogs.msdn.com/obloch/archive/2010/05/03/windows-ce-is-not-dead.aspx As you can read here, Windows Phone 7 keeps its “roots” inside Windows CE. Regarding the .NET Compact Framework, this article from the excellent “I know the answer (it’s 42)” blog from Abhinaba (it seems that we share a passion for photography, Douglas Adams and embedded development), explains that the .NET CF is the foundation of XNA and Silverlight implementation on the WP7 platform: http://blogs.msdn.com/abhinaba/archive/2010/03/18/what-is-netcf.aspx So Windows CE is here to stay, powering one of the most interesting smart phone platforms and ready to power also your devices. Add those blogs to your RSS reader list and stay tuned for more good news about CE and the Compact Framework!

  • Is Intellisense faster in Visual Studio 2012 compared to Visual Studio 2010 for C++ projects?

    - by syplex
    We switched to VS2010 from VS2003 a few months ago, and there are many many improvements. But the speed of Intellisense is not one of them (although it does generate higher quality results, which is great). I read that Intellisense and the MSDN help system were being improved in VS2012, so I'm curious if its actually faster? The only data I could find were graphs of an early release (VS2011). For the record, I am using a vanilla install of VS2010 with SP1 on Windows 7 SP1 (x64). No plugins or add-ins running. What I'm looking for specifically: Has the speed of intellisense autocomplete improved? Has the speed of F12 (goto definition) improved? The answers to these questions will help in determining if VS2012 is worth the money to upgrade at this time as the intellisense slowness would be the only major reason for upgrading. I'd also be interested in knowing if the help system has improved. I'm currently using MSDN help from VS2008SP1 because it has filtering and is faster.

  • 10 tape technology features that make you go hmm.

    - by Karoly Vegh
    A week ago an Oracle/StorageTek Tape Specialist, Christian Vanden Balck, visited Vienna, and agreed to visit customers to do techtalks and update them about the technology boom going around tape. I had the privilege to attend some of his sessions and noted the information and features that took the customers by surprise and made them think. Allow me to share the top 10: I. StorageTek as a brand: StorageTek is one of he strongest names in the Tape field. The brand itself was valued so much by customers that even after Sun Microsystems acquiring StorageTek and the Oracle acquiring Sun the brand lives on with all the Oracle tapelibraries are officially branded StorageTek.See http://www.oracle.com/us/products/servers-storage/storage/tape-storage/overview/index.html II. Disk information density limitations: Disk technology struggles with information density. You haven't seen the disk sizes exploding lately, have you? That's partly because there are physical limits on a disk platter. The size is given, the number of platters is limited, they just can't grow, and are running out of physical area to write to. Now, in a T10000C tape cartridge we have over 1000m long tape. There you go, you have got your physical space and don't need to stuff all that data crammed together. You can write in a reliable pattern, and have space to grow too. III. Oracle has a market share of 62% worldwide in recording head manufacturing. That's right. If you are running LTO drives, with a good chance you rely on StorageTek production. That's two out of three LTO recording heads produced worldwide.  IV. You can store 1 Exabyte data in a single tape library. Yes, an Exabyte. That is 1000 Petabytes. Or, a million Terabytes. A thousand million GigaBytes. You can store that in a stacked StorageTek SL8500 tapelibrary. In one SL8500 you can put 10.000 T10000C cartridges, that store 10TB data (compressed). You can stack 10 of these SL8500s together. Boom. 1000.000 TB.(n.b.: stacking means interconnecting the libraries. Yes, cartridges are moved between the stacked libraries automatically.)  V. EMC: 'Tape doesn't suck after all. We moved on.': Do you remember the infamous 'Tape sucks, move on' Datadomain slogan? Of course they had to put it that way, having only had disk products. But here's a fun fact: on the EMCWorld 2012 there was a major presence of a Tape-tech company - EMC, in a sudden burst of sanity is embracing tape again. VI. The miraculous T10000C: Oracle StorageTek has developed an enterprise-grade tapedrive and cartridge, the T10000C. With awesome numbers: The Cartridge: Native 5TB capacity, 10TB with compression Over a kilometer long tape within the cartridge. And it's locked when unmounted, no rattling of your data.  Replaced the metalparticles datalayer with BaFe (bariumferrite) - metalparticles lose around 7% of magnetism within 30 days. BaFe does not. Yes we employ solid-state physicists doing R&D on demagnetisation in our labs. Can be partitioned, storage tiering within the cartridge!  The Drive: 2GB Cache Encryption implemented in HW - no performance hit 252 MB/s native sustained data rate, beats disk technology by far. Not to mention peak throughput.  Leading the tape while never touching the data side of it, protecting your data physically too Data integritiy checking (CRC recalculation) on tape within the drive without having to read it back to the server reordering data from tape-order, delivering it back in application-order  writing 32 tracks at once, reading them back for CRC check at once VII. You only use 20% of your data on a regular basis. The rest 80% is just lying around for years. On continuously spinning disks. Doubly consuming energy (power+cooling), blocking diskstorage capacity. There is a solution called SAM (Storage Archive Manager) that provides you a filesystem unifying disk and tape, moving data on-demand and for clients transparently between the different storage tiers. You can share these filesystems with NFS or CIFS for clients, and enjoy the low TCO of tape. Tapes don't spin. They sit quietly in their slots, storing 10TB data, using no energy, producing no heat, automounted when a client accesses their data.See: http://www.oracle.com/us/products/servers-storage/storage/storage-software/storage-archive-manager/overview/index.html VIII. HW supported for three decades: Did you know that the original PowderHorn library was released in '87 and has been only discontinued in 2010? That is over two decades of supported operation. Tape libraries are - just like the data carrying on tapecartridges - built for longevity. Oh, and the T10000C cartridge has 30-year archival life for long-term retention.  IX. Tape is easy to manage: Have you heard of Tape Storage Analytics? It is a central graphical tool to summarize, monitor, analyze dataflow, health and performance of drives and libraries, see: http://www.oracle.com/us/products/servers-storage/storage/tape-storage/tape-analytics/overview/index.html X. The next generation: The T10000B drives were able to reuse the T10000A cartridges and write on them even more data. On the same cartridges. We call this investment protection, and this is very important for Oracle for the future too. We usually support two generations of cartridges together. The current drive is a T10000C. (...I know I promised to enlist 10, but I got still two more I really want to mention. Allow me to work around the problem: ) X++. The TallBots, the robots moving around the cartridges in the StorageTek library from tapeslots to the drives are cableless. Cables, belts, chains running to moving parts in a library cause maintenance downtimes. So StorageTek eliminated them. The TallBots get power, commands, even firmwareupgrades through the rails they are running on. Also, the TallBots don't just hook'n'pull the tapes out of their slots, they actually grip'n'lift them out. No friction, no scratches, no zillion little plastic particles floating around in the library, in the drives, on your data. (X++)++: Tape beats SSDs and Disks. In terms of throughput (252 MB/s), in terms of TCO: disks cause around 290x more power and cooling, in terms of capacity: 10TB on a single media and soon more.  So... do you need to store large amounts of data? Are you legally bound to archive it for dozens of years? Would you benefit from automatic storage tiering? Have you got large mediachunks to be streamed at times? Have you got power and cooling issues in the growing datacenters? Do you find EMC's 180° turn of tape attitude interesting, but appreciate it at the same time? With all that, you aren't alone. The most data on this planet is stored on tape. Tape is coming. Big time.

  • External File Upload Optimizations for Windows Azure

    - by rgillen
    [Cross posted from here: http://rob.gillenfamily.net/post/External-File-Upload-Optimizations-for-Windows-Azure.aspx] I’m wrapping up a bit of the work we’ve been doing on data movement optimizations for cloud computing and the latest set of data yielded some interesting points I thought I’d share. The work done here is not really rocket science but may, in some ways, be slightly counter-intuitive and therefore seemed worthy of posting. Summary: for those who don’t like to read detailed posts or don’t have time, the synopsis is that if you are uploading data to Azure, block your data (even down to 1MB) and upload in parallel. Set your block size based on your source file size, but if you must choose a fixed value, use 1MB. Following the above will result in significant performance gains… upwards of 10x-24x and a reduction in overall file transfer time of upwards of 90% (eg, uploading a 1GB file averaged 46.37 minutes prior to optimizations and averaged 1.86 minutes afterwards). Detail: For those of you who want more detail, or think that the claims at the end of the preceding paragraph are over-reaching, what follows is information and code supporting these claims. As the title would indicate, these tests were run from our research facility pointing to the Azure cloud (specifically US North Central as it is physically closest to us) and do not represent intra-cloud results… we have performed intra-cloud tests and the overall results are similar in notion but the data rates are significantly different as well as the tipping points for the various block sizes… this will be detailed separately). We started by building a very simple console application that would loop through a directory and upload each file to Azure storage. This application used the shipping storage client library from the 1.1 version of the azure tools. The only real variation from the client library is that we added code to collect and record the duration (in ms) and size (in bytes) for each file transferred. The code is available here. We then created a directory that had a collection of files for the following sizes: 2KB, 32KB, 64KB, 128KB, 512KB, 1MB, 5MB, 10MB, 25MB, 50MB, 100MB, 250MB, 500MB, 750MB, and 1GB (50 files for each size listed). These files contained randomly-generated binary data and do not benefit from compression (a separate discussion topic). Our file generation tool is available here. The baseline was established by running the application described above against the directory containing all of the data files. This application uploads the files in a random order so as to avoid transferring all of the files of a given size sequentially and thereby spreading the affects of periodic Internet delays across the collection of results.  We then ran some scripts to split the resulting data and generate some reports. The raw data collected for our non-optimized tests is available via the links in the Related Resources section at the bottom of this post. For each file size, we calculated the average upload time (and standard deviation) and the average transfer rate (and standard deviation). As you likely are aware, transferring data across the Internet is susceptible to many transient delays which can cause anomalies in the resulting data. It is for this reason that we randomized the order of source file processing as well as executed the tests 50x for each file size. We expect that these steps will yield a sufficiently balanced set of results. Once the baseline was collected and analyzed, we updated the test harness application with some methods to split the source file into user-defined block sizes and then to upload those blocks in parallel (using the PutBlock() method of Azure storage). The parallelization was handled by simply relying on the Parallel Extensions to .NET to provide a Parallel.For loop (see linked source for specific implementation details in Program.cs, line 173 and following… less than 100 lines total). Once all of the blocks were uploaded, we called PutBlockList() to assemble/commit the file in Azure storage. For each block transferred, the MD5 was calculated and sent ensuring that the bits that arrived matched was was intended. The timer for the blocked/parallelized transfer method wraps the entire process (source file splitting, block transfer, MD5 validation, file committal). A diagram of the process is as follows: We then tested the affects of blocking & parallelizing the transfers by running the updated application against the same source set and did a parameter sweep on the block size including 256KB, 512KB, 1MB, 2MB, and 4MB (our assumption was that anything lower than 256KB wasn’t worth the trouble and 4MB is the maximum size of a block supported by Azure). The raw data for the parallel tests is available via the links in the Related Resources section at the bottom of this post. This data was processed and then compared against the single-threaded / non-optimized transfer numbers and the results were encouraging. The Excel version of the results is available here. Two semi-obvious points need to be made prior to reviewing the data. The first is that if the block size is larger than the source file size you will end up with a “negative optimization” due to the overhead of attempting to block and parallelize. The second is that as the files get smaller, the clock-time cost of blocking and parallelizing (overhead) is more apparent and can tend towards negative optimizations. For this reason (and is supported in the raw data provided in the linked worksheet) the charts and dialog below ignore source file sizes less than 1MB. (click chart for full size image) The chart above illustrates some interesting points about the results: When the block size is smaller than the source file, performance increases but as the block size approaches and then passes the source file size, you see decreasing benefit to the point of negative gains (see the values for the 1MB file size) For some of the moderately-sized source files, small blocks (256KB) are best As the size of the source file gets larger (see values for 50MB and up), the smallest block size is not the most efficient (presumably due, at least in part, to the increased number of blocks, increased number of individual transfer requests, and reassembly/committal costs). Once you pass the 250MB source file size, the difference in rate for 1MB to 4MB blocks is more-or-less constant The 1MB block size gives the best average improvement (~16x) but the optimal approach would be to vary the block size based on the size of the source file.    (click chart for full size image) The above is another view of the same data as the prior chart just with the axis changed (x-axis represents file size and plotted data shows improvement by block size). It again highlights the fact that the 1MB block size is probably the best overall size but highlights the benefits of some of the other block sizes at different source file sizes. This last chart shows the change in total duration of the file uploads based on different block sizes for the source file sizes. Nothing really new here other than this view of the data highlights the negative affects of poorly choosing a block size for smaller files.   Summary What we have found so far is that blocking your file uploads and uploading them in parallel results in significant performance improvements. Further, utilizing extension methods and the Task Parallel Library (.NET 4.0) make short work of altering the shipping client library to provide this functionality while minimizing the amount of change to existing applications that might be using the client library for other interactions.   Related Resources Source code for upload test application Source code for random file generator ODatas feed of raw data from non-optimized transfer tests Experiment Metadata Experiment Datasets 2KB Uploads 32KB Uploads 64KB Uploads 128KB Uploads 256KB Uploads 512KB Uploads 1MB Uploads 5MB Uploads 10MB Uploads 25MB Uploads 50MB Uploads 100MB Uploads 250MB Uploads 500MB Uploads 750MB Uploads 1GB Uploads Raw Data OData feeds of raw data from blocked/parallelized transfer tests Experiment Metadata Experiment Datasets Raw Data 256KB Blocks 512KB Blocks 1MB Blocks 2MB Blocks 4MB Blocks Excel worksheet showing summarizations and comparisons

  • Custom Session Management using HashTable

    - by kaleidoscope
    ASP.NET session state lets you associate a server-side string or object dictionary containing state data with a particular HTTP client session. A session is defined as a series of requests issued by the same client within a certain period of time, and is managed by associating a session ID with each unique client. The ID is supplied by the client on each request, either in a cookie or as a special fragment of the request URL. The session data is stored on the server side in one of the supported session state stores, which include in-process memory, SQL Server™ database, and the ASP.NET State Server service. The latter two modes enable session state to be shared among multiple Web servers on a Web farm and do not require server affinity. Implement Custom session Handler you need to follow following process : 1. Create class library which will inherit from  SessionStateStoreProviderBase abstract Class. 2. Implement all abstract Method in your base class. 3.Change Mode of session to “Custom” in web.config file and provide Provider as your Namespace with classname. <sessionState mode=”Custom” customProvider=”Namespace.classname”> <Providers> <add name=”Name” type=”Namespace.classname”> </sessionstate> For more Details Please refer following links :   http://msdn.microsoft.com/en-us/magazine/cc163730.aspx http://msdn.microsoft.com/en-us/library/system.web.sessionstate.sessionstatestoreproviderbase.aspx - Chandraprakash, S Technorati Tags: Chandraprakash,Session state Managment

  • 2D Collision masks for handling slopes

    - by JiminyCricket
    I've been looking at the example at: http://create.msdn.com/en-US/education/catalog/tutorial/collision_2d_perpixel and am trying to figure out how to adjust the sprite once a collision has been detected. As David suggested at XNA 4.0 2D sidescroller variable terrain heightmap for walking/collision, I made a few sensor points (feet, sides, bottom center, etc.) and can easily detect when these points actually collide with non-transparent portions of a second texture (simple slope). I'm having trouble with the algorithm of how I would actually adjust the sprite position based on a collision. Say I detect a collision with the slope at the sprite's right foot. How can I scan the slope texture data to find the Y position to place the sprite's foot so it is no longer inside the slope? The way it is stored as a 1D array in the example is a bit confusing, should I try to store the data as a 2D array instead? For test purposes, I'm thinking of just using the slope texture alpha itself as a primitive and easy collision mask (no grass bits or anything besides a simple non-linear slope). Then, as in the example, I find the coordinates of any collisions between the slope texture and the sprite's sensors and mark these special sensor collisions as having occurred. Finally, in the case of moving up a slope, I would scan for the first transparent pixel above (in the texture's Ys at that X) the right foot collision point and set that as the new height of the sprite. I'm a little unclear also on when I should make these adjustments. Collisions are checked on every game.update() so would I quickly change the position of the sprite before the next update is called? I also noticed several people mention that it's best to separate collision checks horizontally and vertically, why is that exactly? Open to any suggestions if this is an inefficient or inaccurate way of handling this. I wish MSDN had provided an example of something like this, I didn't know it would be so much more complex than NES Mario style pure box platforming!

  • Wordnik Accelerator

    - by prabhpreet
    Wow, creating IE Accelerators is superbly easy. If you want to learn how to create one, go here (some MSDN blog) and the MSDN documentation (clearly written). I was fed up of dictionary.com bringing all those popups and the stupid definitions of Google's dictionary. So I decided to scratch my own itch. I randomly stumbled on the site called Wordnik and it provides with all examples plus definitions plus lots more for words and its popup-free (as far as I know). So I decided to write and accelerator. Here is the source code (Yes, this is it): <?xml version="1.0" encoding="utf-8"?> <os:openServiceDescription xmlns:os="http://www.microsoft.com/schemas/openservicedescription/1.0"> <os:homepageUrl>http://www.wordnik.com</os:homepageUrl> <os:display> <os:name>View on Wordnik</os:name> <os:description>Looking up words on an awesome word site called Wordnik </os:description> <os:icon>http://www.wordnik.com/favicon.ico</os:icon> </os:display> <os:activity category="Define"> <os:activityAction context="selection"> <os:execute method="get" action="http://www.wordnik.com/words/{selection}" ></os:execute> </os:activityAction> </os:activity> </os:openServiceDescription> That’s it.

  • Mohsen Agsen on C++

    - by raccoon_tim
    As I already blogged a while back, native code has been on the lips of many since TechEd 2011. Microsoft seems very committed to actually putting the language to use again after all these years of radio silence. Regarding this I urge you all guys to watch this video interview of Mohsen Agsen about C++ Today and Tomorrow http://channel9.msdn.com/Shows/Going+Deep/Mohsen-Agsen-C-Today-and-Tomorrow on Channel 9. What I find very inspiring about this interview is that Microsoft has a number of internal projects where they are using C++ and they really understand the value of C++ as a highly performant programming language. He also talks about combining managed code, scripted code and native code to get the most out of each of them. This is something that we are doing a lot in the game industry, since we recognize the need for performant platform code with an easy to write scripting layer on top of that. This is something I intend to blog about in the near future, so stay tuned! Another great thing that I bumped into recently is C++ AMP that was announced at this year’s AMD Fusion Developer Summit. I would recommend watching Herb Sutter’s keynote on the subject at http://channel9.msdn.com/posts/AFDS-Keynote-Herb-Sutter-Heterogeneous-Computing-and-C-AMP.

  • Windows Store now open to ALL developers

    - by CSharpZealot
    A little late, but it should be announced here too... Today’s an especially great day to be a developer. We’re very excited to announce the last significant milestone in the rollout of the Windows Store before the general availability of Windows 8 on October 26. The Store is now open for app submissions from all developers – individuals and companies – in our supported markets, and we’ve added 82 more app submission markets! Now, developers from 120 markets can publish Windows Store apps. Ted Dworkin, Partner Program Manager for the Store, authored this post. --Antoine Source: http://blogs.msdn.com/b/windowsstore/archive/2012/09/11/windows-store-now-open-to-all-developers.aspx About two weeks ago the Windows Store was opened and with the upcoming general availability of Windows 8 in October, it seems that it was good timing. In addition to the store being opened, Microsoft also announced that the MSDN, BizSpark and DreamSpark will get a 1-year Windows Store developer account. That's a different tact than what we saw for the Windows Phone 7, where we didn't get that subscription included. We're already seeing new apps showing up faster and faster, so with the addition of 86 more markets we're only going to see more apps than ever available. Since i'm now back on a Windows 8 platform (was out for about a month) I'm going to start blogging more content around the Windows 8 developer experience. Next stop for me...get my hands on a Windows 8 surface device as quickly as possible :) Keep coding!

  • "System.Data.OracleClient requires Oracle client software version 8.1.7 or greater." Error Message

    - by Jandost Khoso
    Quick resolution: Give full permission to AUTHENTICATED USERS in following folders. a) ORACLE_HOME b) Program Files\ORACLE   Check your PATH. You might have installed different clients in your system and your .NET application is pointing to a home with inappoperiate client. What your .NET application should load is OCI.DLL with File version more than 8.1.7. According to the MSDN document Oracle and ADO.NET:   "The .NET Framework Data Provider for Oracle provides access to an Oracle database using the Oracle Call Interface (OCI) as provided by Oracle Client software. The functionality of the data provider is designed to be similar to that of the .NET Framework data providers for SQL Server, OLE DB, and ODBC. "     The MSDN document System Requirements (Oracle) says: "The .NET Framework Data Provider for Oracle requires Microsoft Data Access Components (MDAC) version 2.6 or later. MDAC 2.8 SP1 is recommended. You must also have Oracle 8i Release 3 (8.1.7) Client or later installed. "   Both the .NET Framework Data Provider for Oracle and Oracle Data Provider for .NET are data providers to access Oracle database. The former ships with .NET Framework and requires Oracle client version 8.1.7 or above. The latter is provided by Oracle company and requires Oracle client version 9.2 or later.     The Oracle Data Provider for .NET (ODP.NET) features optimized ADO.NET data access to the Oracle database. ODP.NET allows developers to take advantage of advanced Oracle database functionality, including Real Application Clusters, XML DB, and advanced security.   See the document Comparing the Microsoft .NET Framework 1.1 Data Provider for Oracle and the Oracle Data Provider for .NET for more information about the difference.

  • Use CompiledQuery.Compile to improve LINQ to SQL performance

    - by Michael Freidgeim
    After reading DLinq (Linq to SQL) Performance and in particular Part 4  I had a few questions. If CompiledQuery.Compile gives so much benefits, why not to do it for all Linq To Sql queries? Is any essential disadvantages of compiling all select queries? What are conditions, when compiling makes whose performance, for how much percentage? World be good to have default on application config level or on DBML level to specify are all select queries to be compiled? And the same questions about Entity Framework CompiledQuery Class. However in comments I’ve found answer  of the author ricom 6 Jul 2007 3:08 AM Compiling the query makes it durable. There is no need for this, nor is there any desire, unless you intend to run that same query many times. SQL provides regular select statements, prepared select statements, and stored procedures for a reason.  Linq now has analogs. Also from 10 Tips to Improve your LINQ to SQL Application Performance   If you are using CompiledQuery make sure that you are using it more than once as it is more costly than normal querying for the first time. The resulting function coming as a CompiledQuery is an object, having the SQL statement and the delegate to apply it.  And your delegate has the ability to replace the variables (or parameters) in the resulting query. However I feel that many developers are not informed enough about benefits of Compile. I think that tools like FxCop and Resharper should check the queries  and suggest if compiling is recommended.

  • Limitations of the SharePoint join using CAML

    - by ybbest
    Limitation One In SharePoint 2010, you can join the primary list to a foreign list and include more than one field from the foreign list. However, the limitation is that the included fields from foreign list have to be the following type: Calculated (treated as plain text) ContentTypeId Counter Currency DateTime Guid Integer Note (one-line only) Number Text The above limitation also explains why you cannot include some types of the fields from the remote list when creating a lookup. Limitation Two When using CAML query to join SharePoint lists, there can be joins to multiple lists, multiple joins to the same list, and chains of joins. However, the limitations are only inner and left outer joins are permitted and the field in the primary list must be a Lookup type field that looks up to the field in the foreign list. Limitation Three The support for writing the JOIN query in CAML is very limited.I have to hand-code the CAML query to join the lists,not fun at all.Although some blogs post mentioned about using LINQ to SharePoint and get the CAML code from there , but I never get it to work.You can check this blog post  for this.Let me know if it works for you.

  • More than one way to skin an Audit

    - by BuckWoody
    I get asked quite a bit about auditing in SQL Server. By "audit", people mean everything from tracking logins to finding out exactly who ran a particular SELECT statement. In the really early versions of SQL Server, we didn't have a great story for very granular audits, so lots of workarounds were suggested. As time progressed, more and more audit capabilities were added to the product, and in typical database platform fashion, as we added a feature we didn't often take the others away. So now, instead of not having an option to audit actions by users, you might face the opposite problem - too many ways to audit! You can read more about the options you have for tracking users here: http://msdn.microsoft.com/en-us/library/cc280526(v=SQL.100).aspx  In SQL Server 2008, we introduced SQL Server Audit, which uses Extended Events to really get a simple way to implement high-level or granular auditing. You can read more about that here: http://msdn.microsoft.com/en-us/library/dd392015.aspx  As with any feature, you should understand what your needs are first. Auditing isn't "free" in the performance sense, so you need to make sure you're only auditing what you need to. Share this post: email it! | bookmark it! | digg it! | reddit! | kick it! | live it!

  • Controlling access to site folders if you cannot user Roles

    - by DavidMadden
    I find myself on an assignment where I could not use System.Web.Security.Roles.  That meant that I could not use Visual Studio's Website | ASP.NET Configuration.  I had to go about things another way.  The clues were in these two websites:http://www.csharpaspnetarticles.com/2009/02/formsauthentication-ticket-roles-aspnet.htmlhttp://msdn.microsoft.com/en-us/library/b6x6shw7(v=VS.71).aspxhttp://msdn.microsoft.com/en-us/library/b6x6shw7(v=VS.71).aspxYou can set in your web.config the restrictions on folders without having to set the restrictions in multiple folders through their own web.config file.  In my main default.aspx file in my protected subfolder off my main site, I did the following code due to MultiFormAuthentication (MFA) providing the security to this point:        string role = string.Empty;         if (((Login)Session["Login"]).UserLevelID > 3)         {             role = "PowerUser";         }         else         {             role = "Newbie";         }         FormsAuthenticationTicket ticket =  new FormsAuthenticationTicket( 1,                 ((Login)Session["Login"]).UserID,                 DateTime.Now,                 DateTime.Now.AddMinutes(20),                 false,                 role,                 FormsAuthentication.FormsCookiePath);         string hashCookies = FormsAuthentication.Encrypt(ticket);         HttpCookie cookie =  new HttpCookie(FormsAuthentication.FormsCookieName, hashCookies);         Response.Cookies.Add(cookie); This all gave me the ability to change restrictions on folders without having to restart the website or having to do any hard coding.
