• Getting Started with Cloud Computing

  - by juanlarios

  You’ve likely heard about how Office 365 and Windows Intune are great applications to get you started with Cloud Computing. Many of you emailed me asking for more info on what Cloud Computing is, including the distinction between "Public Cloud" and "Private Cloud". I want to address these questions and help you get started. Let's begin with a brief set of definitions and some places to find more info; however, an excellent place where you can always learn more about Cloud Computing is the Microsoft Virtual Academy. Public Cloud computing means that the infrastructure to run and manage the applications users are taking advantage of is run by someone else and not you. In other words, you do not buy the hardware or software to run your email or other services being used in your organization – that is done by someone else. Users simply connect to these services from their computers and you pay a monthly subscription fee for each user that is taking advantage of the service. Examples of Public Cloud services include Office 365, Windows Intune, Microsoft Dynamics CRM Online, Hotmail, and others. Private Cloud computing generally means that the hardware and software to run services used by your organization is run on your premises, with the ability for business groups to self-provision the services they need based on rules established by the IT department. Generally, Private Cloud implementations today are found in larger organizations but they are also viable for small and medium-sized businesses since they generally allow an automation of services and reduction in IT workloads when properly implemented. Having the right management tools, like System Center 2012, to implement and operate Private Cloud is important in order to be successful. So – how do you get started? The first step is to determine what makes the most sense to your organization. The nice thing is that you do not need to pick Public or Private Cloud – you can use elements of both where it makes sense for your business – the choice is yours. When you are ready to try and purchase Public Cloud technologies, the Microsoft Volume Licensing web site is a good place to find links to each of the online services. In particular, if you are interested in a trial for each service, you can visit the following pages: Office 365, CRM Online, Windows Intune, and Windows Azure. For Private Cloud technologies, start with some of the courses on Microsoft Virtual Academy and then download and install the Microsoft Private Cloud technologies including Windows Server 2008 R2 Hyper-V and System Center 2012 in your own environment and take it for a spin. Also, keep up to date with the Canadian IT Pro blog to learn about events Microsoft is delivering such as the IT Virtualization Boot Camps and more to get you started with these technologies hands on. Finally, I want to ask for your help to allow the team at Microsoft to continue to provide you what you need. Twice a year through something we call "The Global Relationship Study" – they reach out and contact you to see how they're doing and what Microsoft could do better. If you get an email from "Microsoft Feedback" with the subject line "Help Microsoft Focus on Customers and Partners" between March 5th and April 13th, please take a little time to tell them what you think.

• 2012&ndash;The End Of The World Review

  - by Tim Murphy

  The end of the world must be coming.  Not because the Mayan calendar says so, but because Microsoft is innovating more than Apple.  It has been a crazy year, with pundits declaring not that the end of the world is coming, but that the end of Microsoft is coming.  Let’s take a look at what 2012 has brought us. The beginning of year is a blur.  I managed to get to TechEd in June which was the first time that I got to take a deep dive into Windows 8 and many other things that had been announced in 2011.  The promise I saw in these products was really encouraging.  The thought of being able to run Windows 8 from a thumb drive or have Hyper-V native to the OS told me that at least for developers good things were coming. I finally got my feet wet with Windows 8 with the developer preview just prior to the RTM.  While the initial experience was a bit of a culture shock I quickly grew to love it.  The media still seems to hold little love for the “reimagined” platform, but I think that once people spend some time with it they will enjoy the experience and what the FUD mongers say will fade into the background.  With the launch of the OS we finally got a look at the Surface.  I think this is a bold entry into the tablet market.  While I wish it was a little more affordable I am already starting to see them in the wild being used by non-techies. I was waiting for Windows Phone 8 at least as much as Windows 8, probably more.  The new hardware, better marketing and new OS features I think are going to finally push us to the point of having a real presence in the smartphone market.  I am seeing a number of iPhone users picking up a Nokia Lumia 920 and getting rid of their brand new iPhone 5.  The only real debacle that I saw around the launch was when they held back the SDK from general developers. Shortly after the launch events came Build 2012.  I was extremely disappointed that I didn’t make it to this year’s Build.  Even if they weren’t handing out Surface and Lumia devices I think the atmosphere and content were something that really needed to be experience in person.  Hopefully there will be a Build next year and it’s schedule will be announced soon.  As you would expect Windows 8 and Windows Phone 8 development were the mainstay of the conference, but improvements in Azure also played a key role.  This movement of services to the cloud will continue and we need to understand where it best fits into the solutions we build. Lower on the radar this year were Office 2013, SQL Server 2012, and Windows Server 2012.  Their glory stolen by the consumer OS and hardware announcements, these new releases are no less important.  Companies will see significant improvements in performance and capabilities if they upgrade.  At TechEd they had shown some of the new features of Windows Server 2012 around hardware integration and Hyper-V performance which absolutely blew me away.  It is our job to bring these important improvements to our company’s attention so that they can be leveraged. Personally, the consulting business in 2012 was the busiest it has been in a long time.  More companies were ready to attack new projects after several years of putting them on the back burner.  I also worked to bring back momentum to the Chicago Information Technology Architects Group.  Both the community and clients are excited about the new technologies that have come out in 2012 and now it is time to deliver. What does 2013 have in store.  I don’t see it be quite as exciting as 2012.  Microsoft will be releasing the Surface Pro in January and it seems that we will see more frequent OS update for Windows.  There are rumors that we may see a Surface phone in 2013.  It has also been announced that there will finally be a rework of the XBox next fall.  The new year will also be a time for us in the development community to take advantage of these new tools and devices.  After all, it is what we build on top of these platforms that will attract more consumers and corporations to using them. Just as I am 99.999% sure that the world is not going to end this year, I am also sure that Microsoft will move on and that most of this negative backlash from the media is actually fear and jealousy.  In the end I think we have a promising year ahead of us. del.icio.us Tags: Microsoft,Pundits,Mayans,Windows 8,Windows Phone 8,Surface

• New .Net Authentication in 4.5.1

  - by Aligned

  Originally posted on: http://geekswithblogs.net/Aligned/archive/2013/11/05/new-.net-authentication-in-4.5.1.aspxThere has been a lot of traffic on my post about Simple Membership that came with the File new Project MVC 4 in 2012. I was reading the release notes for Visual Studio 2013 and .Net 4.5.1 and it mentioned a new/updated Authentication approach. “ASP.NET Identity is the new membership system for ASP.NET applications. ASP.NET Identity makes it easy to integrate user-specific profile data with application data. ASP.NET Identity also allows you to choose the persistence model for user profiles in your application. You can store the data in a SQL Server database or another data store, including NoSQL data stores such as Windows Azure Storage Tables” There’s a great page on the asp.net site that gives an introduction, overview, how to use it, and how to migrate to it. I won’t be doing a new project for awhile at work, but I’ll definitely be looking into this more when I get the time.

• ASP.NET MVC in a subfolder (only) on godaddy

  - by Anthony Potts

  Okay, I have read many of the routing posts concerning putting asp.net mvc on godaddy. However, I have not come to a solution to my current problem. I am trying to publish an ASP.NET MVC application to a subfolder on godaddy. I have upgraded the account to use IIS 7 and I have included the MVC dlls in \bin\ deployment method. However, I suspect that my route is not correct. Currently, my routes are set up with the standard out of the box route: public static void RegisterRoutes(RouteCollection routes) { routes.IgnoreRoute("{resource}.axd/{*pathInfo}"); routes.MapRoute( "Default", // Route name "{controller}/{action}/{id}", // URL with parameters new { controller = "Home", action = "Index", id = "" } // Parameter defaults ); } I have a subdomain set up so that it looks like office.domain.com. The subdomain is pointing at a folder "/office/" which is right off the root folder. (There is not an MVC application installed in the root folder). All of my application has been placed in this 'office' folder. When I hover over the links however, the 'office' portion shows up in the link as well. e.g. Hovering over a link to the customer controller, index action yields "office.domain.com/office/Customer" as the target. This link then gets a 404 when I attempt to go to it. What should my route be to fix this? Is there something I have neglected in setting up the subdomain in godaddy? Is this something I just can't do in godaddy's domain management "tool". Do I need to set up a virtual directory for this instead of just a directory? Update: I changed the IIS settings in godaddy to use integrated pipeline mode, per this discussion and I am no longer getting 404 errors. The application worked just fine as suggested it would.

• Outlook Addin in C# - How to add button/group in New Mail (next to signatures)

  - by MadBoy

  I'm having some trouble understanding Outlook terms (CommandBarPopup, CommandBarButton etc) like what is what in Outlook so please be patient. I would like to create couple of things: I would like to create new group (or just button but i read it's not possible to add a button to an existing group in ribbon) on new mail next to Signature/Add attachment in Message Ribbon. It would have to work the same way Signature works so when you press it it display couple of options. How can i create it? I would like to override a button "NEW" (where you can choose that you want to send new mail, make appointment or do other things) so that when you are in Main Window when you press the down arrow next to new button you could choose one of options i will add? Is this possible? How do I do it? I have some code that adds a menu in Main Window private void AddMenuBar() { try { //Define the existent Menu Bar menuBar = this.Application.ActiveExplorer().CommandBars.ActiveMenuBar; //Define the new Menu Bar into the old menu bar newMenuBar = (Office.CommandBarPopup) menuBar.Controls.Add(Office.MsoControlType.msoControlPopup, missing, missing, missing, false); //If I dont find the newMenuBar, I add it if (newMenuBar != null) { newMenuBar.Caption = "Test"; newMenuBar.Tag = menuTag; buttonOne = (Office.CommandBarButton) newMenuBar.Controls.Add(Office.MsoControlType.msoControlButton, missing, missing, 1, true); buttonOne.Style = Office.MsoButtonStyle.msoButtonIconAndCaption; buttonOne.Caption = "Test Button"; //This is the Icon near the Text buttonOne.FaceId = 610; buttonOne.Tag = "c123"; //Insert Here the Button1.Click event buttonOne.Click += new Office._CommandBarButtonEvents_ClickEventHandler(ButtonOneClick); newMenuBar.Visible = true; } } catch (Exception ex) { //This MessageBox is visible if there is an error System.Windows.Forms.MessageBox.Show("Error: " + ex.Message.ToString(), "Error Message Box", MessageBoxButtons.OK, MessageBoxIcon.Exclamation); } } I would like to add submenu under the buttonOne so when i press it new submenus open up. How do I achieve that?

• Understanding WordProcessingML tags and avoid unnecessary tags

  - by rithanyalaxmi

  Hi, I am using MS Word API to generate .docx which contains the data fetched from DB, in which i am applying the respective styles, fonts, symbols, etc. If the data fetched from the DB is quite huge, then there is a problem in displaying those data in the .docx file. I found that internally MS Word 2007 will write some content through tags which may not be needed to display the data. Hence i am figuring out what are the necessary MS Word tags needed when converting into a .xml file. So that i can avoid unnecessary tags and build only the respective tags which are needed to display the data. Hence i am planning to write my own .xml with the MS Word tags which are needed, than generating a .XML from .docx file My queries are:- 1) Whether it is right that the MS Word will generate some tags which may not be needed during the conversion of .docx to document.xml? That makes it heavy? If so what are the tags , so that i can avoid them when write by own .xml file. 2) Please send links to understand about the MS Word tags and its advantages, which tags are needed and which are not ? 3) Whether my approach to write a new .xml similar to document.xml (.docx conversion) is worthy one to go forward so that i can build the .xml with the tags i needed , so that i can improve the performance of the data display? Please shed some light into it and thanks in advance.. Thanks, Rithu

• System.Threading.Timer keep reference to it.

  - by Daniel Bryars

  According to [http://msdn.microsoft.com/en-us/library/system.threading.timer.aspx][1] you need to keep a reference to a System.Threading.Timer to prevent it from being disposed. I've got a method like this: private void Delay(Action action, Int32 ms) { if (ms <= 0) { action(); } System.Threading.Timer timer = new System.Threading.Timer( (o) => action(), null, ms, System.Threading.Timeout.Infinite); } Which I don't think keeps a reference to the timer, I've not seen any problems so far, but that's probably because the delay periods used have been pretty small. Is the code above wrong? And if it is, how to I keep a reference to the Timer? I'm thinking something like this might work: class timerstate { internal volatile System.Threading.Timer Timer; }; private void Delay2(Action action, Int32 ms) { if (ms <= 0) { action(); } timerstate state = new timerstate(); lock (state) { state.Timer = new System.Threading.Timer( (o) => { lock (o) { action(); ((timerstate)o).Timer.Dispose(); } }, state, ms, System.Threading.Timeout.Infinite); } The locking business is so I can get the timer into the timerstate class before the delegate gets invoked. It all looks a little clunky to me. Perhaps I should regard the chance of the timer firing before it's finished constructing and assigned to the property in the timerstace instance as negligible and leave the locking out.

• C#: How to access an Excel cell?

  - by tksy

  I am trying to open an Excel file and populate its cells with data? I have done the following coding so far. Currently I am at this stage with the following code but still I am getting errors: Microsoft.Office.Interop.Excel.ApplicationClass appExcel = new Microsoft.Office.Interop.Excel.ApplicationClass(); try { // is there already such a file ? if (System.IO.File.Exists("C:\\csharp\\errorreport1.xls")) { // then go and load this into excel Microsoft.Office.Interop.Excel.Workbooks.Open( "C:\\csharp\\errorreport1.xls", true, false, Missing.Value, Missing.Value, Missing.Value, Missing.Value, Missing.Value, Missing.Value, Missing.Value, Missing.Value, Missing.Value, Missing.Value, Missing.Value, Missing.Value); } else { // if not go and create a workbook: newWorkbook = appExcel.Workbooks.Add(XlWBATemplate.xlWBATWorksheet); Microsoft.Office.Interop.Excel._Worksheet excelWorksheet = (Microsoft.Office.Interop.Excel._Worksheet) newWorkBook.Worksheets.get_Item(1); } i++; j = 1; j++; objsheet.Cells(i, j).Value = "Tabelle: " + rs.Fields["Table_Name"]; j++; objsheet.Cells(i, j).Value = "kombinationsschluessel:FALL " + rs3.Fields[1].Value; j++; objsheet.Cells(i, j).Value = "Null Value: "; j++; objsheet.Cells(i, j).Value = "Updated with 888"; These are the top 2 errors I am getting: Error 1 An object reference is required for the nonstatic field, method, or property 'Microsoft.Office.Interop.Excel.Workbooks.Open(string, object, object, object, object, object, object, object, object, object, object, object, object, object, object)' Error 2 The name 'newWorkbook' does not exist in the current context

• General String Encryption in .NET

  - by cryptospin

  I am looking for a general string encryption class in .NET. (Not to be confused with the 'SecureString' class.) I have started to come up with my own class, but thought there must be a .NET class that already allows you to encrypt/decrypt strings of any encoding with any Cryptographic Service Provider. Public Class SecureString Private key() As Byte Private iv() As Byte Private m_SecureString As String Public ReadOnly Property Encrypted() As String Get Return m_SecureString End Get End Property Public ReadOnly Property Decrypted() As String Get Return Decrypt(m_SecureString) End Get End Property Public Sub New(ByVal StringToSecure As String) If StringToSecure Is Nothing Then StringToSecure = "" m_SecureString = Encrypt(StringToSecure) End Sub Private Function Encrypt(ByVal StringToEncrypt As String) As String Dim result As String = "" Dim bytes() As Byte = Text.Encoding.UTF8.GetBytes(StringToEncrypt) Using provider As New AesCryptoServiceProvider() With provider .Mode = CipherMode.CBC .GenerateKey() .GenerateIV() key = .Key iv = .IV End With Using ms As New IO.MemoryStream Using cs As New CryptoStream(ms, provider.CreateEncryptor(), CryptoStreamMode.Write) cs.Write(bytes, 0, bytes.Length) cs.FlushFinalBlock() End Using result = Convert.ToBase64String(ms.ToArray()) End Using End Using Return result End Function Private Function Decrypt(ByVal StringToDecrypt As String) As String Dim result As String = "" Dim bytes() As Byte = Convert.FromBase64String(StringToDecrypt) Using provider As New AesCryptoServiceProvider() Using ms As New IO.MemoryStream Using cs As New CryptoStream(ms, provider.CreateDecryptor(key, iv), CryptoStreamMode.Write) cs.Write(bytes, 0, bytes.Length) cs.FlushFinalBlock() End Using result = Text.Encoding.UTF8.GetString(ms.ToArray()) End Using End Using Return result End Function End Class

• Silverlight WinDg Memory Release Issue

  - by Chris Newton

  Hi, I have used WinDbg succesfully on a number of occasions to track down and fix memory leaks (or more accurately the CLRs inability to garbage collect a released object), but am stuck with one particular control. The control is displayed within a child window and when the window is closed a reference to the control remains and cannot be garbage collected. I have resolved what I believe to be the majority of the issues that could have caused the leak, but the !gcroot of the affected object is not clear (to me at least) as to what is still holding on to this object. The ouput is always the same regardless of the content being presented in the child window: DOMAIN(03FB7238):HANDLE(Pinned):79b12f8:Root: 06704260(System.Object[])- 05719f00(System.Collections.Generic.Dictionary2[[System.IntPtr, mscorlib],[System.Object, mscorlib]])-> 067c1310(System.Collections.Generic.Dictionary2+Entry[[System.IntPtr, mscorlib],[System.Object, mscorlib]][])- 064d42b0(System.Windows.Controls.Grid)- 064d4314(System.Collections.Generic.Dictionary2[[MS.Internal.IManagedPeerBase, System.Windows],[System.Object, mscorlib]])-> 064d4360(System.Collections.Generic.Dictionary2+Entry[[MS.Internal.IManagedPeerBase, System.Windows],[System.Object, mscorlib]][])- 064d3860(System.Windows.Controls.Border)- 064d4218(System.Collections.Generic.Dictionary2[[MS.Internal.IManagedPeerBase, System.Windows],[System.Object, mscorlib]])-> 064d4264(System.Collections.Generic.Dictionary2+Entry[[MS.Internal.IManagedPeerBase, System.Windows],[System.Object, mscorlib]][])- 064d3bfc(System.Windows.Controls.ContentPresenter)- 064d3d64(System.Collections.Generic.Dictionary2[[MS.Internal.IManagedPeerBase, System.Windows],[System.Object, mscorlib]])-> 064d3db0(System.Collections.Generic.Dictionary2+Entry[[MS.Internal.IManagedPeerBase, System.Windows],[System.Object, mscorlib]][])- 064d3dec(System.Collections.Generic.Dictionary2[[System.UInt32, mscorlib],[System.Windows.DependencyObject, System.Windows]])-> 064d3e38(System.Collections.Generic.Dictionary2+Entry[[System.UInt32, mscorlib],[System.Windows.DependencyObject, System.Windows]][])- 06490b04(Insurer.Analytics.SharedResources.Controls.HistoricalKPIViewerControl) If anyone has any ideas about what could potentially be the problem, or if you require more information, please let me know.

• How can I create an Image in GDI+ from a Base64-Encoded string in C++?

  - by Schnapple

  I have an application, currently written in C#, which can take a Base64-encoded string and turn it into an Image (a TIFF image in this case), and vice versa. In C# this is actually pretty simple. private byte[] ImageToByteArray(Image img) { MemoryStream ms = new MemoryStream(); img.Save(ms, System.Drawing.Imaging.ImageFormat.Tiff); return ms.ToArray(); } private Image byteArrayToImage(byte[] byteArrayIn) { MemoryStream ms = new MemoryStream(byteArrayIn); BinaryWriter bw = new BinaryWriter(ms); bw.Write(byteArrayIn); Image returnImage = Image.FromStream(ms, true, false); return returnImage; } // Convert Image into string byte[] imagebytes = ImageToByteArray(anImage); string Base64EncodedStringImage = Convert.ToBase64String(imagebytes); // Convert string into Image byte[] imagebytes = Convert.FromBase64String(Base64EncodedStringImage); Image anImage = byteArrayToImage(imagebytes); (and, now that I'm looking at it, could be simplified even further) I now have a business need to do this in C++. I'm using GDI+ to draw the graphics (Windows only so far) and I already have code to decode the string in C++ (to another string). What I'm stumbling on, however, is getting the information into an Image object in GDI+. At this point I figure I need either a) A way of converting that Base64-decoded string into an IStream to feed to the Image object's FromStream function b) A way to convert the Base64-encoded string into an IStream to feed to the Image object's FromStream function (so, different code than I'm currently using) c) Some completely different way I'm not thinking of here. My C++ skills are very rusty and I'm also spoiled by the managed .NET platform, so if I'm attacking this all wrong I'm open to suggestions.

• Mono & DeflateStream

  I have a simple code byte[] buffer = Encoding.UTF8.GetBytes("abracadabra"); MemoryStream ms = new MemoryStream(); DeflateStream ds = new DeflateStream(ms, CompressionMode.Compress, false); ms.Write(buffer, 0, buffer.Length); DeflateStream ds2 = new DeflateStream(ms, CompressionMode.Decompress, false); byte[] buffer2 = new byte[ms.Length]; ds2.Read(buffer2, 0, (int)ms.Length); Console.WriteLine(Encoding.UTF8.GetString(buffer2)); And when reading from ds2, i have the following: Stacktrace: at (wrapper managed-to-native) System.IO.Compression.DeflateStream.ReadZStream (intptr,intptr,int) <0x00004 at (wrapper managed-to-native) System.IO.Compression.DeflateStream.ReadZStream (intptr,intptr,int) <0x00004 at System.IO.Compression.DeflateStream.ReadInternal (byte[],int,int) [0x00031] in C:\cygwin\tmp\monobuild\build\BUILD\mono-2.6.3\mcs\class\System\System.IO.Compression\DeflateStream.cs:192 at System.IO.Compression.DeflateStream.Read (byte[],int,int) [0x00086] in C:\cygwin\tmp\monobuild\build\BUILD\mono-2.6.3\mcs\class\System\System.IO.Compression\DeflateStream.cs:214 at testtesttest.MainClass.Main (string[]) [0x00041] in C:\Users\ilukyanov\Desktop\Cassini\GZipDemo\Main.cs:27 at (wrapper runtime-invoke) .runtime_invoke_void_object (object,intptr,intptr,intptr) This application has requested the Runtime to terminate it in an unusual way.

• C++ AI Design Question

  - by disney

  Hi, I am currently writing a bot for a MMORPG. Though, currently I am stuck at trying to figure out how to nicely implement this. The design problem is related to casting the character spells in the correct order. Here is a simple example to what I need to archieve. It's not related to casting them, but doing it in the correct order. I would know how simply cast them randomly, by checking which skill has not yet been casted, but in right order as being shown in the GUI, not really. note: the skill amount may differ, it's not always 3, maximum 10 though. Charactername < foobar has 3 skills. Skill 1: Name ( random1 ) cooldown ( 1000 ms ) cast duration ( 500 ms ) Skill 2: Name ( random2 ) cooldown ( 1500 ms ) cast duration ( 700 ms ) Skill 3: Name ( random3 ) cooldown ( 2000 ms ) cast duration ( 900 ms ) I don't really know how I could implement this, if anyone has some thoughts, feel free to share. I do know that most of the people don't like the idea of cheating in games, I don't like it either, nor I am actually playing the game, but its an interesting field for me. Thank you.

• Solutions to cubefarm lighting

  - by Khorkrak

  So with our recent move to the cubefarm out from our developer friendly shared office, we've altered the environment to reproduce our more programming conducive workspace as much as possible. Fortunately, we we're planted into the same aisle as QA. They're quiet and it's made it easier to pair up to review a problem. They've already unscrewed some of the fluorescent bulbs. We unscrewed the rest. Now the facilities coordinator and HR are wondering what to do. They want the office to have an open, bright and elegant feel to it as does the founder - think IKEA. Fortunately he's usually in the NYC office and rarely stops up where we work. There's some natural light from nearby windows and translucent office walls that ring the farm. So the facility coordinator doesn't understand - do you guys want incandescents overhead or... no we just don't want overhead lights. How to solve this while avoiding having a weird looking office space with a dark spot in the middle. Are there any better solutions - no we can't have an office as that's considered a management only perk.

• Error Using 32 vs. 64 bit SharePoint 2007 DLLs with PowerShell

  - by Brian Jackett

  Next time you fire up PowerShell to work with the SharePoint API make sure you launch the proper bit version of PowerShell.  Last week I had an interesting error that led to this blog post.  Travel back in time a little bit with me to see where this 32 vs. 64 bit debate started. History     Ever since the first pre-beta bits of Office 2010 landed in my lap I have been questioning whether it’s better to run 32 or 64 bit applications on a 64 bit host operating system.  In relation to Office 2010 I heard a number of arguments for 32 bit including this link from the Office 2010 Engineering team.  Given my typical usage scenarios 32 bit seemed the way to go since I wasn’t a “super RAM hungry” Excel user or the like. The Problem     Since I had chosen 32 bit Office 2010, I tried to stick with 32 bit version of other programs that I run assuming the same benefits and rules applied to other applications.  This is where I was wrong.  Last week I was attempting to use 32 bit PowerShell ISE (Integrated Scripting Environment) on a 64 bit WSS 3.0 server.  When trying to reference the 64 bit SharePoint DLLs I got the following errors about not being able to find the web application.     I have run into these errors when I have hosts file issues or improper permissions to the farm / site collection but these were not the case.  After taking a quick spin around the interwebs I ran across the below forum post comment and another MSDN forum reply that explained the error.  Turns out that sometimes it’s not possible to run 32 bit applications against a 64 bit OS / farm / assembly / etc. …the problem could also be because your SharePoint is 64-Bit but your app is running in 32-bit mode     I quickly exited 32 bit PowerShell ISE and ran the same code under 64 bit PowerShell ISE.  All errors were gone and the script ran successfully.   Conclusion     The rules of 32 vs. 64 bit interoperability do not always apply evenly across all applications and scenarios.  In my case I wasn’t able to run 32 bit PowerShell against 64 bit SharePoint DLLs.  I’m updating all of my links and shortcuts to use 64 bit PowerShell where appropriate.  I’m quite surprised it has taken me this long to run into this error, but sometimes blind luck is all that keeps you from running into errors.  Lesson learned and hopefully this can benefit you as well.  Happy SharePointing all!         -Frog Out   Links http://blogs.technet.com/b/office2010/archive/2010/02/23/understanding-64-bit-office.aspx http://social.msdn.microsoft.com/Forums/en-US/sharepointdevelopment/thread/a732cb83-c2ef-4133-b04e-86477b72bbe3/ http://stackoverflow.com/questions/266255/filenotfoundexception-with-the-spsite-constructor-whats-the-problem

• Ubuntu Server Cannot Route to the Internet

  - by ejes

  I've been having this problem for weeks now, and I can't seem to figure out the problem. My server can route the local network and serves it well, however it cannot access the internet. It can't be the router because everything else on this lan can route through the router. I've even switched the ethernet port. Any help would be appreciated. I've tried all the usual places, anyway, here are the configs: root@uhs:~# uname -a Linux uhs 3.0.0-16-generic-pae #28-Ubuntu SMP Fri Jan 27 19:24:01 UTC 2012 i686 i686 i386 GNU/Linux root@uhs:~# cat /etc/network/interfaces # This file describes the network interfaces available on your system # and how to activate them.

• Data Governance (Veri Yönetisimi)

  - by Arda Eralp

  Data governance,veri ile ilgili islemler için bir sorumluluklar sistemidir. Bu sistemin temelini ise politikalar, standartlar ve prosedürler olusturur. Sistem politikalar, standartlar ve prosedürler sayesinde verinin ne zaman, hangi sartlar altinda, hangi eylemlerde, hangi yöntemler ile kimler tarafindan kullanilacagina karar verir. Sistemin kurumda basarili bir sekilde islemesi için öncelikle kurumda farkindalik saglanmasi gereklidir. Farkindalik saglandiktan sonra ise kurum governance ve mimari kültürünü benimsemelidir. Ancak bu sartlar altinda sistem basarili bir sekilde isleyebilecektir. Bu sebeplerden dolayidir ki data governance kisa bir süreç degil, aksine kurum varligini sürdürdügü sürece isleyecek olan bir süreçtir. Bu durum bize data governance in bir proje degil bir program oldugunu açiklamaktadir. Programin baslangicinda kurumun ihtiyaçlarinin netlesmesi ve farkindaligin saglanmasi temeldir. Hedef kitle ise, veri ile dogrudan ve ya dolayli olarak iliski içerisinde olan herkesdir. Bu sebeple programin baslangicinda hedef kitleyi içeren ekipler ile toplantilar düzenlenecektir. Bu toplantilar sayesinde hem farkindalik saglanacak hemde ekiplerin ihtiyaçlari birebir ekipler tarafindan aktarilarak netlesecektir. Hedef kitlenin ihtiyaçlari netlestirildikten sonra ise devamli isleyecek olan bu sürecin planlamasi yapilacaktir. Bu sürecin planlanmasinda ihtiyaçlarin önceliklendirilmesi gerekmektedir. Sebebi ise her ekibin ihtiyaçlarinin farkli olabilecegi ve bütün ihtiyaçlara ayni anda karsilik verilemeyebileceginin öngörülmesidir. Bu öngörünün temeli ise ekiplerin ihtiyaçlarinin birbirleriyle olan baglantisidir. Süreç planlamasinda ihtiyaçlarin önceliklendirilmesinin ardindan kurumun büyüklügünün gözönünde bulundurulmasi gerekmedir. Kurumun büyüklügünün önemi ise eger kurum bir bütün olarak ayni anda govern edilemeyecek kadar büyük ise ihtiyaçlari öncelikli olarak bulunan ekipler ile govern edilmesine baslanarak sürecin belirli bir hiz ile bütün kurumda isler hale getirilmesini saglamaktir. Ihtiyaçlar belirlendikten ve ilgili ekipler seçildikten sonra artik programin planlanmasina geçilebilecek. Programin planlama asamasinda öncelikli olarak sürecin asamalarini kontrol edecek ve süreç kurum içerisinde isleyise geçtiginde kontrolü saglayacak olan Data Governance Office in planlanmasidir. Office in planlanmasiyla birlikte süreçteki roller ve bu rollerin sorumluluklari belirlenecektir. Planlama asamasinda Data governance office, roller ve sorumluluklar, güvenlik ve veri saklanan sistemler ele alinacak konulardir. Planlama asamasi tamamlandiginda ise belirlenen ekipler ve ihtiyaçlar dogrultusunda programin isleyis asamasina geçilebilecektir. Isleyis kisminda ekibin ihtiyaçlari dogrultusunda güvenlik konusunda ve veri saklanan sistemler üzerinde çalismalar yapilacaktir. Bu yapilan çalismalar bir süreç olarak dökümante edilecek ve süreç sona erdiginde baska bir ekiple baska bir ihtiyaç dogrultusunda çalisma yapilarak ayni süreç isletilecek ve böylece kurum içesinde ilgili süreçte standartlasma saglanacaktir. Güvenlik konusunda verinin erisim güvenligi ve kullanim güvenligi ele alinacaktir. Veri saklanan sistemler üzerindeki çalismalar ise saklanan sistemlerin program dahilinde belirlenen standartlar ile olusturulmasi ve yönetilmesi saglanacaktir. Isleyis kisminin ardindan ise programin izleme kismina geçilecektir. Bu kisimda artik Data Governance Office olusmus, politikalar, standartlar ve prosedürler belirlenmistir. Ve Data Governance Office çalisanlari rolleri ve sorumluluklari dahilinde programin isleyisini izleyecek ve gerek gördügünde politikalar standartlar ve prosedürler üzerinde degisiklikler yapacaklardir.

• OOF checklist

  - by Daniel Moth

  When going on vacation or otherwise being out of office (known as OOF in Microsoft), it is polite and professional that our absence creates the minimum disruption possible to the rest of the business, and especially our colleagues. Below is my OOF checklist - I try to do these as soon as I know I'll be OOF, rather than leave it for the night before. Let the relevant folks on the team know the planned dates of absence and check if anybody was expecting something from you during that timeframe. Reset expectations with them, and as applicable try to find another owner for individual activities that cannot wait. Go through your calendar for the OOF period and decline every meeting occurrence so the owner of the meeting knows that you won't be attending (similar to my post about responding to invites). If it is your meeting cancel it so that people don’t turn up without the meeting organizer being there. Do this even for meetings were the folks should know due to step #1. Over-communicating is a good thing here and keeps calendars all around up to date. Enter your OOF dates in whatever tool your company uses. Typically that is the notification to your manager. In your Outlook calendar, create a local Appointment (don't invite anyone) for the date range (All day event) setting the "Show As" dropdown to "Out of Office". This way, people won’t try to schedule meetings with you on that day. If you use Lync, set the status to "Off Work" for that period. If you won't be responding to email (which when on your vacation you definitely shouldn't) then in Outlook setup "Automatic Replies (Out of Office)" for that period. This way people won’t think you are rude when not replying to their emails. In your OOF message point to an alias (ideally of many people) as a fallback for urgent queries. If you want to proactively notify individuals of your OOFage then schedule and send a multi-day meeting request for the entire period. Remember to set the "Show As" to "Free" (so their calendar doesn’t show busy/oof to others), set the "Reminder" to "None" (so they don’t get a reminder about it), set "Low Importance", and uncheck both "Response Options" so if they don't want this on their calendar, it is just one click for them to get rid of it. Aside: I have another post with advice on sending invites. If you care about people who would not observe the above but could drop by your office, stick a physical OOF note at your office door or chair/monitor or desk. Have I missed any? Comments about this post by Daniel Moth welcome at the original blog.

• CPU and Data alignment

  - by MS

  Dear All, Pardon me if you feel this has been answered numerous times, but I need answers to the following queries! Why data has to be aligned (on 4 byte/ 8 byte/ 2 byte boundaries)? Here my doubt is when the CPU has address lines Ax Ax-1 Ax-2 ... A2 A1 A0 then it is quite possible to address the memory locations sequentially. So why there is the need to align the data at specific boundaries? How to find the alignment requirements when I am compiling my code and generating the executatble? If for e.g the data alignment is 4 byte boundary, does that mean each consecutive byte is located at modulo 4 offsets? My doubt is if data is 4 byte aligned does that mean that if a byte is at 1004 then the next byte is at 1008 (or at 1005)? Your thoughts are much welcome. Thanks in advance! /MS

• C# Confusing Results from Performance Test

  - by aip.cd.aish

  I am currently working on an image processing application. The application captures images from a webcam and then does some processing on it. The app needs to be real time responsive (ideally < 50ms to process each request). I have been doing some timing tests on the code I have and I found something very interesting (see below). clearLog(); log("Log cleared"); camera.QueryFrame(); camera.QueryFrame(); log("Camera buffer cleared"); Sensor s = t.val; log("Sx: " + S.X + " Sy: " + S.Y); Image<Bgr, Byte> cameraImage = camera.QueryFrame(); log("Camera output acuired for processing"); Each time the log is called the time since the beginning of the processing is displayed. Here is my log output: [3 ms]Log cleared [41 ms]Camera buffer cleared [41 ms]Sx: 589 Sy: 414 [112 ms]Camera output acuired for processing The timings are computed using a StopWatch from System.Diagonostics. QUESTION 1 I find this slightly interesting, since when the same method is called twice it executes in ~40ms and when it is called once the next time it took longer (~70ms). Assigning the value can't really be taking that long right? QUESTION 2 Also the timing for each step recorded above varies from time to time. The values for some steps are sometimes as low as 0ms and sometimes as high as 100ms. Though most of the numbers seem to be relatively consistent. I guess this may be because the CPU was used by some other process in the mean time? (If this is for some other reason, please let me know) Is there some way to ensure that when this function runs, it gets the highest priority? So that the speed test results will be consistently low (in terms of time). EDIT I change the code to remove the two blank query frames from above, so the code is now: clearLog(); log("Log cleared"); Sensor s = t.val; log("Sx: " + S.X + " Sy: " + S.Y); Image<Bgr, Byte> cameraImage = camera.QueryFrame(); log("Camera output acuired for processing"); The timing results are now: [2 ms]Log cleared [3 ms]Sx: 589 Sy: 414 [5 ms]Camera output acuired for processing The next steps now take longer (sometimes, the next step jumps to after 20-30ms, while the next step was previously almost instantaneous). I am guessing this is due to the CPU scheduling. Is there someway I can ensure the CPU does not get scheduled to do something else while it is running through this code?

• Why is numpy's einsum faster than numpy's built in functions?

  - by Ophion

  Lets start with three arrays of dtype=np.double. Timings are performed on a intel CPU using numpy 1.7.1 compiled with icc and linked to intel's mkl. A AMD cpu with numpy 1.6.1 compiled with gcc without mkl was also used to verify the timings. Please note the timings scale nearly linearly with system size and are not due to the small overhead incurred in the numpy functions if statements these difference will show up in microseconds not milliseconds: arr_1D=np.arange(500,dtype=np.double) large_arr_1D=np.arange(100000,dtype=np.double) arr_2D=np.arange(500**2,dtype=np.double).reshape(500,500) arr_3D=np.arange(500**3,dtype=np.double).reshape(500,500,500) First lets look at the np.sum function: np.all(np.sum(arr_3D)==np.einsum('ijk->',arr_3D)) True %timeit np.sum(arr_3D) 10 loops, best of 3: 142 ms per loop %timeit np.einsum('ijk->', arr_3D) 10 loops, best of 3: 70.2 ms per loop Powers: np.allclose(arr_3D*arr_3D*arr_3D,np.einsum('ijk,ijk,ijk->ijk',arr_3D,arr_3D,arr_3D)) True %timeit arr_3D*arr_3D*arr_3D 1 loops, best of 3: 1.32 s per loop %timeit np.einsum('ijk,ijk,ijk->ijk', arr_3D, arr_3D, arr_3D) 1 loops, best of 3: 694 ms per loop Outer product: np.all(np.outer(arr_1D,arr_1D)==np.einsum('i,k->ik',arr_1D,arr_1D)) True %timeit np.outer(arr_1D, arr_1D) 1000 loops, best of 3: 411 us per loop %timeit np.einsum('i,k->ik', arr_1D, arr_1D) 1000 loops, best of 3: 245 us per loop All of the above are twice as fast with np.einsum. These should be apples to apples comparisons as everything is specifically of dtype=np.double. I would expect the speed up in an operation like this: np.allclose(np.sum(arr_2D*arr_3D),np.einsum('ij,oij->',arr_2D,arr_3D)) True %timeit np.sum(arr_2D*arr_3D) 1 loops, best of 3: 813 ms per loop %timeit np.einsum('ij,oij->', arr_2D, arr_3D) 10 loops, best of 3: 85.1 ms per loop Einsum seems to be at least twice as fast for np.inner, np.outer, np.kron, and np.sum regardless of axes selection. The primary exception being np.dot as it calls DGEMM from a BLAS library. So why is np.einsum faster that other numpy functions that are equivalent? The DGEMM case for completeness: np.allclose(np.dot(arr_2D,arr_2D),np.einsum('ij,jk',arr_2D,arr_2D)) True %timeit np.einsum('ij,jk',arr_2D,arr_2D) 10 loops, best of 3: 56.1 ms per loop %timeit np.dot(arr_2D,arr_2D) 100 loops, best of 3: 5.17 ms per loop The leading theory is from @sebergs comment that np.einsum can make use of SSE2, but numpy's ufuncs will not until numpy 1.8 (see the change log). I believe this is the correct answer, but have not been able to confirm it. Some limited proof can be found by changing the dtype of input array and observing speed difference and the fact that not everyone observes the same trends in timings.

• Is there any way that an export-to-Excel function can be scalable?

  - by MusiGenesis

  Summary: ASP.Net website with a couple hundred users. Data is exported to Excel files which can be relatively large (~5 MB). In the pilot phase (just a few users), we are already seeing occasional errors on the server in the exporting method. Here's the stack trace: System.Web.HttpUnhandledException: Exception of type 'System.Web.HttpUnhandledException' was thrown. --- System.OutOfMemoryException: Exception of type 'System.OutOfMemoryException' was thrown. at System.IO.MemoryStream.set_Capacity(Int32 value) at System.IO.MemoryStream.EnsureCapacity(Int32 value) at System.IO.MemoryStream.Write(Byte[] buffer, Int32 offset, Int32 count) at MS.Internal.IO.Packaging.TrackingMemoryStream.Write(Byte[] buffer, Int32 offset, Int32 count) at MS.Internal.IO.Packaging.SparseMemoryStream.WriteAndCollapseBlocks(Byte[ ] buffer, Int32 offset, Int32 count) at MS.Internal.IO.Packaging.SparseMemoryStream.Write(Byte[] buffer, Int32 offset, Int32 count) at MS.Internal.IO.Packaging.CompressEmulationStream.Write(Byte[] buffer, Int32 offset, Int32 count) at MS.Internal.IO.Packaging.CompressStream.Write(Byte[] buffer, Int32 offset, Int32 count) at MS.Internal.IO.Zip.ProgressiveCrcCalculatingStream.Write(Byte[] buffer, Int32 offset, Int32 count) at MS.Internal.IO.Zip.ZipIOModeEnforcingStream.Write(Byte[] buffer, Int32 offset, Int32 count) at System.IO.StreamWriter.Flush(Boolean flushStream, Boolean flushEncoder) at System.IO.StreamWriter.Write(String value) at System.Xml.XmlTextEncoder.Write(String text) at System.Xml.XmlTextWriter.WriteString(String text) at System.Xml.XmlText.WriteTo(XmlWriter w) at System.Xml.XmlAttribute.WriteContentTo(XmlWriter w) at System.Xml.XmlAttribute.WriteTo(XmlWriter w) at System.Xml.XmlElement.WriteTo(XmlWriter w) at System.Xml.XmlElement.WriteContentTo(XmlWriter w) at System.Xml.XmlElement.WriteTo(XmlWriter w) at System.Xml.XmlElement.WriteContentTo(XmlWriter w) at System.Xml.XmlElement.WriteTo(XmlWriter w) at System.Xml.XmlElement.WriteContentTo(XmlWriter w) at System.Xml.XmlElement.WriteTo(XmlWriter w) at System.Xml.XmlDocument.WriteContentTo(XmlWriter xw) at System.Xml.XmlDocument.WriteTo(XmlWriter w) at System.Xml.XmlDocument.Save(Stream outStream) at OfficeOpenXml.ExcelWorksheet.Save() in C:\temp\XXXXXXXXXX\ExcelPackage\ExcelWorksheet.cs:line 605 at OfficeOpenXml.ExcelWorkbook.Save() in C:\temp\XXXXXXXXXX\ExcelPackage\ExcelWorkbook.cs:line 439 at OfficeOpenXml.ExcelPackage.Save() in C:\temp\XXXXXXXXXX\ExcelPackage\ExcelPackage.cs:line 348 at Framework.Exporting.Business.ExcelExport.BuildReport(HttpContext context) at WebUserControl.BtnXLS_Click(Object sender, EventArgs e) in C:\TEMP\XXXXXXXXXX\XXXXXXXXXX\OneList\UserControls\TicketReportExporter. ascx.cs:line 108 at System.Web.UI.WebControls.Button.OnClick(EventArgs e) at System.Web.UI.WebControls.Button.RaisePostBackEvent(String eventArgument) at System.Web.UI.WebControls.Button.System.Web.UI.IPostBackEventHandler.Rai sePostBackEvent(String eventArgument) at System.Web.UI.Page.RaisePostBackEvent(IPostBackEventHandler sourceControl, String eventArgument) at System.Web.UI.Page.RaisePostBackEvent(NameValueCollection postData) at System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint) --- End of inner exception stack trace --- at System.Web.UI.Page.HandleError(Exception e) at System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint) at System.Web.UI.Page.ProcessRequest(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint) at System.Web.UI.Page.ProcessRequest() at System.Web.UI.Page.ProcessRequestWithNoAssert(HttpContext context) at System.Web.UI.Page.ProcessRequest(HttpContext context) at ASP.XXXXXXXXXXX_aspx.ProcessRequest(HttpContext context) in c:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\Temporary ASP.NET Files\XXXX\cdf32a52\d1a5eabd\App_Web_enxdwlks.1.cs:line 0 at System.Web.HttpApplication.CallHandlerExecutionStep.System.Web.HttpAppli cation.IExecutionStep.Execute() at System.Web.HttpApplication.ExecuteStep(IExecutionStep step, Boolean& completedSynchronously) Even aside from this particular problem, in general exporting to Excel requires the instantiation of huge Excel objects on the server for each request, which I've always assumed to mean disqualifies Excel for "serious" work on a highly-loaded server. Is there any general way to export to Excel in a "light-weight" manner? Would simply streaming the data into a CSV file work for this?

• Azure Mobile Services: lessons learned

  - by svdoever

  When I first started using Azure Mobile Services I thought of it as a nice way to: authenticate my users - login using Twitter, Google, Facebook, Windows Live create tables, and use the client code to create the columns in the table because that is not possible in the Azure Mobile Services UI run some Javascript code on the table crud actions (Insert, Update, Delete, Read) schedule a Javascript to run any 15 or more minutes I had no idea of the magic that was happening inside… where is the data stored? Is it a kind of big table, are relationships between tables possible? those Javascripts on the table crud actions, is that interpreted, what is that exactly? After working for some time with Azure Mobile Services I became a lot wiser: Those tables are just normal tables in an Azure SQL Server 2012 Creating the table columns through client code sucks, at least from my Javascript code, because the columns are deducted from the sent JSON data, and a datetime field is sent as string in JSON, so a string type column is created instead of a datetime column You can connect with SQL Management Studio to the Azure SQL Server, and although you can’t manage your columns through the SQL Management Studio UI, it is possible to just run SQL scripts to drop and create tables and indices When you create a table through SQL script, add the table with the same name in the Azure Mobile Services UI to hook it up and be able to access the table through the provided abstraction layer You can also go to the SQL Database through the Azure Mobile Services UI, and from there get in a web based SQL management studio where you can create columns and manage your data The table crud scripts and the scheduler scripts are full blown node.js scripts, introducing a lot of power with great performance The web based script editor is really powerful, I do most of my editing currently in the editor which has syntax highlighting and code completing. While editing the code JsHint is used for script validation. The documentation on Azure Mobile Services is… suboptimal. It is such a pity that there is no way to comment on it so the community could fill in the missing holes, like which node modules are already loaded, and which modules are available on Azure Mobile Services. Soon I was hacking away on Azure Mobile Services, creating my own database tables through script, and abusing the read script of an empty table named query to implement my own set of “services”. The latest updates to Azure Mobile Services described in the following posts added some great new features like creating web API’s, use shared code from your scripts, command line tools for managing Azure Mobile Services (upload and download scripts for example), support for node modules and git support: http://weblogs.asp.net/scottgu/archive/2013/06/14/windows-azure-major-updates-for-mobile-backend-development.aspx http://blogs.msdn.com/b/carlosfigueira/archive/2013/06/14/custom-apis-in-azure-mobile-services.aspx http://blogs.msdn.com/b/carlosfigueira/archive/2013/06/19/custom-api-in-azure-mobile-services-client-sdks.aspx In the mean time I rewrote all my “service-like” table scripts to API scripts, which works like a breeze. Bad thing with the current state of Azure Mobile Services is that the git support is not working if you are a co-administrator of your Azure subscription, and not and administrator (as in my case). Another bad thing is that Cross Origin Request Sharing (CORS) is not supported for the API yet, so no go yet from the browser client for API’s, which is my case. See http://social.msdn.microsoft.com/Forums/windowsazure/en-US/2b79c5ea-d187-4c2b-823a-3f3e0559829d/known-limitations-for-source-control-and-custom-api-features for more on these and other limitations. In his talk at Build 2013 Josh Twist showed that there is a work-around for accessing shared script code from the table scripts as well (another limitation mentioned in the post above). I could not find that code in the Votabl2 code example from the presentation at https://github.com/joshtwist/votabl2, but we can grab it from the presentation when it comes online on Channel9. By the way: you can always express your needs and ideas at http://mobileservices.uservoice.com, that’s the place they are listening to (I hope!).
