• CreationName for SSIS 2008 and adding components programmatically

  If you are building SSIS 2008 packages programmatically and adding data flow components, you will probably need to know the creation name of the component to add. I can never find a handy reference when I need one, hence this rather mundane post. See also CreationName for SSS 2005. We start with a very simple snippet for adding a component: // Add the Data Flow Task package.Executables.Add("STOCK:PipelineTask"); // Get the task host wrapper, and the Data Flow task TaskHost taskHost = package.Executables[0] as TaskHost; MainPipe dataFlowTask = (MainPipe)taskHost.InnerObject; // Add OLE-DB source component - ** This is where we need the creation name ** IDTSComponentMetaData90 componentSource = dataFlowTask.ComponentMetaDataCollection.New(); componentSource.Name = "OLEDBSource"; componentSource.ComponentClassID = "DTSAdapter.OLEDBSource.2"; So as you can see the creation name for a OLE-DB Source is DTSAdapter.OLEDBSource.2.

• Hue, saturation, brightness, contrast effect in hlsl

  - by Vibhore Tanwer

  I am new to pixel shader, and I am trying to write a simple brightness, contrast, hue, saturation effect. I have written a shader for it but I doubt that my shader is not providing me correct result, Brightness, contrast, saturation is working fine, problem is with hue. if I apply hue between -1 to 1, it seems to be working fine, but to make things more sharp, I need to apply hue value between -180 and 180, like we can apply hue in Paint.NET. Here is my code. // Amount to shift the Hue, range 0 to 6 float Hue; float Brightness; float Contrast; float Saturation; float Alpha; sampler Samp : register(S0); // Converts the rgb value to hsv, where H's range is -1 to 5 float3 rgb_to_hsv(float3 RGB) { float r = RGB.x; float g = RGB.y; float b = RGB.z; float minChannel = min(r, min(g, b)); float maxChannel = max(r, max(g, b)); float h = 0; float s = 0; float v = maxChannel; float delta = maxChannel - minChannel; if (delta != 0) { s = delta / v; if (r == v) h = (g - b) / delta; else if (g == v) h = 2 + (b - r) / delta; else if (b == v) h = 4 + (r - g) / delta; } return float3(h, s, v); } float3 hsv_to_rgb(float3 HSV) { float3 RGB = HSV.z; float h = HSV.x; float s = HSV.y; float v = HSV.z; float i = floor(h); float f = h - i; float p = (1.0 - s); float q = (1.0 - s * f); float t = (1.0 - s * (1 - f)); if (i == 0) { RGB = float3(1, t, p); } else if (i == 1) { RGB = float3(q, 1, p); } else if (i == 2) { RGB = float3(p, 1, t); } else if (i == 3) { RGB = float3(p, q, 1); } else if (i == 4) { RGB = float3(t, p, 1); } else /* i == -1 */ { RGB = float3(1, p, q); } RGB *= v; return RGB; } float4 mainPS(float2 uv : TEXCOORD) : COLOR { float4 col = tex2D(Samp, uv); float3 hsv = rgb_to_hsv(col.xyz); hsv.x += Hue; // Put the hue back to the -1 to 5 range //if (hsv.x > 5) { hsv.x -= 6.0; } hsv = hsv_to_rgb(hsv); float4 newColor = float4(hsv,col.w); float4 colorWithBrightnessAndContrast = newColor; colorWithBrightnessAndContrast.rgb /= colorWithBrightnessAndContrast.a; colorWithBrightnessAndContrast.rgb = colorWithBrightnessAndContrast.rgb + Brightness; colorWithBrightnessAndContrast.rgb = ((colorWithBrightnessAndContrast.rgb - 0.5f) * max(Contrast + 1.0, 0)) + 0.5f; colorWithBrightnessAndContrast.rgb *= colorWithBrightnessAndContrast.a; float greyscale = dot(colorWithBrightnessAndContrast.rgb, float3(0.3, 0.59, 0.11)); colorWithBrightnessAndContrast.rgb = lerp(greyscale, colorWithBrightnessAndContrast.rgb, col.a * (Saturation + 1.0)); return colorWithBrightnessAndContrast; } technique TransformTexture { pass p0 { PixelShader = compile ps_2_0 mainPS(); } } Please If anyone can help me learning what am I doing wrong or any suggestions? Any help will be of great value. EDIT: Images of the effect at hue 180: On the left hand side, the effect I got with @teodron answer. On the right hand side, The effect Paint.NET gives and I'm trying to reproduce.

• What are developer's problems with helpful error messages?

  - by Moo-Juice

  It continue to astounds me that, in this day and age, products that have years of use under their belt, built by teams of professionals, still to this day - fail to provide helpful error messages to the user. In some cases, the addition of just a little piece of extra information could save a user hours of trouble. A program that generates an error, generated it for a reason. It has everything at its disposal to inform the user as much as it can, why something failed. And yet it seems that providing information to aid the user is a low-priority. I think this is a huge failing. One example is from SQL Server. When you try and restore a database that is in use, it quite rightly won't let you. SQL Server knows what processes and applications are accessing it. Why can't it include information about the process(es) that are using the database? I know not everyone passes an Applicatio_Name attribute on their connection string, but even a hint about the machine in question could be helpful. Another candidate, also SQL Server (and mySQL) is the lovely string or binary data would be truncated error message and equivalents. A lot of the time, a simple perusal of the SQL statement that was generated and the table shows which column is the culprit. This isn't always the case, and if the database engine picked up on the error, why can't it save us that time and just tells us which damned column it was? On this example, you could argue that there may be a performance hit to checking it and that this would impede the writer. Fine, I'll buy that. How about, once the database engine knows there is an error, it does a quick comparison after-the-fact, between values that were going to be stored, versus the column lengths. Then display that to the user. ASP.NET's horrid Table Adapters are also guilty. Queries can be executed and one can be given an error message saying that a constraint somewhere is being violated. Thanks for that. Time to compare my data model against the database, because the developers are too lazy to provide even a row number, or example data. (For the record, I'd never use this data-access method by choice, it's just a project I have inherited!). Whenever I throw an exception from my C# or C++ code, I provide everything I have at hand to the user. The decision has been made to throw it, so the more information I can give, the better. Why did my function throw an exception? What was passed in, and what was expected? It takes me just a little longer to put something meaningful in the body of an exception message. Hell, it does nothing but help me whilst I develop, because I know my code throws things that are meaningful. One could argue that complicated exception messages should not be displayed to the user. Whilst I disagree with that, it is an argument that can easily be appeased by having a different level of verbosity depending on your build. Even then, the users of ASP.NET and SQL Server are not your typical users, and would prefer something full of verbosity and yummy information because they can track down their problems faster. Why to developers think it is okay, in this day and age, to provide the bare minimum amount of information when an error occurs? It's 2011 guys, come on.

• Add Windows 7’s AeroSnap Feature to Vista and XP

  - by Asian Angel

  Are you using Windows Vista or XP and want that Windows 7 AeroSnap goodness on your own system? Then join us as we look at AeroSnap for Windows Vista and XP. Note: Requires .NET Framework 2.0 or higher (link provided at bottom of article). Setup What exactly does AeroSnap do you might ask…here is a quote directly from the website: “AeroSnap is a simple but powerful application that allows you to resize, arrange or maximize your desktop windows with just drag’n'drop. Simply drag a window to a side of your desktop to snap it or drag it to the top to maximize. When you drag it back to the last position, the last window size will be restored.” As soon as you have finished installing AeroSnap and started it for the first time the only item that will be visible is the “System Tray Icon”. Before going any further you should take a moment to view and make any desired adjustments in the “Options”. Note: AeroSnap works with multiple monitors. You may want to have AeroSnap start with Windows each time but the really nice setting to enable here is the “Snap Preview”. If you are using AeroSnap on Vista and have Aero enabled this will really be nice. The second portion may be of interest for those who would like to enable the keyboard shortcut function. One point worth noting about this screen is that the highest number of pixels from the screen’s edge that you can set AeroSnap for is 20 pixels. AeroSnap in Action AeroSnap is extremely easy to use…just grab the top of an app window and drag it to the left, right, or top of your screen. Since we installed this on Windows Vista we made certain to enable the “Snap Preview” in the “Options”.  We started off with dragging our Firefox 3.7 window towards the left…once we got close to the edge of the screen you can see that the left half of the screen temporarily “shaded over”. Note: The “Snap Preview” displays on the left and right movements but not the top movement. Releasing Firefox snapped it right into the “shaded over” part of the screen. The great thing about AeroSnap is that it is really easy to return the app window to it former size…all that you have to do is simply click on and grab the top portion of the app window. Moving Firefox towards the top of our screen and… It quickly snaps into filling the screen. One thing that we did notice is that the window did not “Maximize” as per the function for the button in the upper right corner. Dragging towards the right side now… And snap! Tucked in all nice and neat… You can minimize the app windows to the Taskbar and they will return to their previous “snap area” when “maximized” again. Conclusion If you have been wanting to add Windows 7’s AeroSnap goodness to your Vista and XP systems then you should definitely give this app a try. AeroSnap is very easy to set up and operate… Links Download AeroSnap for Windows Vista & XP Download the .NET Framework Similar Articles Productive Geek Tips Using Windows 7 or Vista System RestoreRoundup: 16 Tweaks to Windows Vista Look & FeelSelect Files using Check Boxes in Windows VistaSpeed up Your Windows Vista Computer with ReadyBoostHow-To Geek Bounty: $103.24(Paid!) for Active Desktop for Vista TouchFreeze Alternative in AutoHotkey The Icy Undertow Desktop Windows Home Server – Backup to LAN The Clear & Clean Desktop Use This Bookmarklet to Easily Get Albums Use AutoHotkey to Assign a Hotkey to a Specific Window Latest Software Reviews Tinyhacker Random Tips DVDFab 6 Revo Uninstaller Pro Registry Mechanic 9 for Windows PC Tools Internet Security Suite 2010 Add a Custom Title in IE using Spybot or Spyware Blaster When You Need to Hail a Taxi in NYC Live Map of Marine Traffic NoSquint Remembers Site Specific Zoom Levels (Firefox) New Firefox release 3.6.3 fixes 1 Critical bug Dark Side of the Moon (8-bit)

• Installer Reboots at "Detecting hardware" (disks and other hardware) on all recent Server Installs

  - by Ryan Rosario

  I have a very frustrating problem with my PC. I cannot install any recent version of Ubuntu Server (or even Desktop) since 9.04 even using the text-based installer. I boot from a USB stick created by Unetbootin (I also tried other methods such as startup disk creator with no difference). On the Server installer, it gets to "Detecting Hardware" (the second one about disks and all other hardware, not network hardware) and then either hangs at 0% (waited 24 hours), or reboots after a minute or two. My system (late 2007): ASUS P5NSLI motherboard Intel Core 2 Duo E6600 2.4Ghz 2 x 1GB Corsair 667MHz RAM nVidia GeForce 6600 I have unplugged everything (including the only hard disk, CD-ROMs and floppy). I have only one stick of RAM (tried each one to no avail) and am booting the installer from a USB stick (booting from CD-ROM yields the same problem). I also tried several of the boot options (nomodeset, nousb, acpi=off, noapic, i915.modeset=1/0, xforcevesa) in all combinations) to no avail. The only active parts of my system are the video card, mouse, keyboard and USB stick. I have also updated the BIOS to the most recent version. (FWIW, on the Desktop installer, I get a black screen after hitting the Install option.) Even after removing "quiet" I am unable to see what kernel panic is occurring (or not occurring) to cause the install to crash. I am only able to save the debug logs via a simple webserver in the installer. After the last line (I repeatedly refreshed), the server stops responding and the installer hangs or reboots: Jan 2 01:04:03 main-menu[302]: INFO: Menu item 'disk-detect' selected Jan 2 01:04:04 kernel: [ 309.154372] sata_nv 0000:00:0e.0: version 3.5 Jan 2 01:04:04 kernel: [ 309.154409] sata_nv 0000:00:0e.0: Using SWNCQ mode Jan 2 01:04:04 kernel: [ 309.154531] sata_nv 0000:00:0e.0: setting latency timer to 64 Jan 2 01:04:04 kernel: [ 309.164442] scsi0 : sata_nv Jan 2 01:04:04 kernel: [ 309.167610] scsi1 : sata_nv Jan 2 01:04:04 kernel: [ 309.167762] ata1: SATA max UDMA/133 cmd 0x9f0 ctl 0xbf0 bmdma 0xd400 irq 10 Jan 2 01:04:04 kernel: [ 309.167774] ata2: SATA max UDMA/133 cmd 0x970 ctl 0xb70 bmdma 0xd408 irq 10 Jan 2 01:04:04 kernel: [ 309.167948] sata_nv 0000:00:0f.0: Using SWNCQ mode Jan 2 01:04:04 kernel: [ 309.168071] sata_nv 0000:00:0f.0: setting latency timer to 64 Jan 2 01:04:04 kernel: [ 309.171931] scsi2 : sata_nv Jan 2 01:04:04 kernel: [ 309.173793] scsi3 : sata_nv Jan 2 01:04:04 kernel: [ 309.173943] ata3: SATA max UDMA/133 cmd 0x9e0 ctl 0xbe0 bmdma 0xe800 irq 11 Jan 2 01:04:04 kernel: [ 309.173954] ata4: SATA max UDMA/133 cmd 0x960 ctl 0xb60 bmdma 0xe808 irq 11 Jan 2 01:04:04 kernel: [ 309.174061] pata_amd 0000:00:0d.0: version 0.4.1 Jan 2 01:04:04 kernel: [ 309.174160] pata_amd 0000:00:0d.0: setting latency timer to 64 Jan 2 01:04:04 kernel: [ 309.177045] scsi4 : pata_amd Jan 2 01:04:04 kernel: [ 309.178628] scsi5 : pata_amd Jan 2 01:04:04 kernel: [ 309.178801] ata5: PATA max UDMA/133 cmd 0x1f0 ctl 0x3f6 bmdma 0xf000 irq 14 Jan 2 01:04:04 kernel: [ 309.178811] ata6: PATA max UDMA/133 cmd 0x170 ctl 0x376 bmdma 0xf008 irq 15 Jan 2 01:04:04 net/hw-detect.hotplug: Detected hotpluggable network interface eth0 Jan 2 01:04:04 net/hw-detect.hotplug: Detected hotpluggable network interface lo Jan 2 01:04:04 kernel: [ 309.485062] ata3: SATA link down (SStatus 0 SControl 300) Jan 2 01:04:04 kernel: [ 309.633094] ata1: SATA link up 3.0 Gbps (SStatus 123 SControl 300) Jan 2 01:04:04 kernel: [ 309.641647] ata1.00: ATA-8: ST31000528AS, CC38, max UDMA/133 Jan 2 01:04:04 kernel: [ 309.641658] ata1.00: 1953525168 sectors, multi 1: LBA48 NCQ (depth 31/32) Jan 2 01:04:04 kernel: [ 309.657614] ata1.00: configured for UDMA/133 Jan 2 01:04:04 kernel: [ 309.657969] scsi 0:0:0:0: Direct-Access ATA ST31000528AS CC38 PQ: 0 ANSI: 5 Jan 2 01:04:04 kernel: [ 309.658482] sd 0:0:0:0: Attached scsi generic sg0 type 0 Jan 2 01:04:04 kernel: [ 309.658588] sd 0:0:0:0: [sda] 1953525168 512-byte logical blocks: (1.00 TB/931 GiB) Jan 2 01:04:04 kernel: [ 309.658812] sd 0:0:0:0: [sda] Write Protect is off Jan 2 01:04:04 kernel: [ 309.658823] sd 0:0:0:0: [sda] Mode Sense: 00 3a 00 00 Jan 2 01:04:04 kernel: [ 309.658918] sd 0:0:0:0: [sda] Write cache: enabled, read cache: enabled, doesn't support DPO or FUA Jan 2 01:04:04 kernel: [ 309.675630] sda: sda1 sda2 Jan 2 01:04:04 kernel: [ 309.676440] sd 0:0:0:0: [sda] Attached SCSI disk Jan 2 01:04:05 kernel: [ 309.969102] ata2: SATA link down (SStatus 0 SControl 300) Jan 2 01:04:05 kernel: [ 310.281137] ata4: SATA link down (SStatus 0 SControl 300) Anybody have any additional ideas I could try?

  - by Dave Campbell

  In this Issue: Carlos Figueira(-2-), Subodh Pushpak, Gergely Orosz, John Papa, Mike Snow(-2-), Rishi, Tim Heuer, Stefan Olson, and David Anson. Shoutouts: Josh Holmes blogged about a cool app the City of Miami has up: Miami 311: Built on Windows Azure Gergely Orosz reports on the state of a bug he found pre SL4: Silverlight 4 still displays large elements incorrectly Laura Foy and Charlie Kindel discuss WP7 on Channel 9: Windows Phone 7 Developer Tools Refresh Announced Charlie Kindel has an announcement, good instructions, and what's new notes on the Windows Phone Developer Tools CTP Refresh! Tim Heuer mentioned the workaround for this in his post (below), but I thought you might like to read Brandon Watson's debrief of what it's all about: Signed Assemblies Bug in the Windows Phone Tools CTP Refresh Laurent Bugnion posted about interrelations between versions of Blend and WP7 code... read it closely: Be careful when installing the Blend Windows Phone 7 Add-In From SilverlightCream.com: Consuming REST/POX services in Silverlight 4 Carlos Figueira has a pair of posts up about consuming services in Silverlight 4. This first one is about consuming REST/POX services. He provides a Service Contract that can be used with either and the full project code is available as well. Consuming REST/JSON services in Silverlight 4 In the second post, Carlos Figueira provides the code to allow WCF and Silverlight 4 to consume strongly-typed REST/JSON... and again, all the code is available. Silverlight and WCF caching Subodh Pushpak has a post up discussing caching in WCF, and has code demonstrating turning caching on at run-time. Detecting Silverlight Version Installed Gergely Orosz said it right when he said "Detecting the Silverlight version installed on a client machine isn’t entirely straightforward." ... and after reading this post, if you take the link to his ScottLogic blog, you'll get a full break-out of how it's done. Silverlight TV 22: Tim Heuer on Extending the SMF It's Thursday, and that means Silverlight TV! ... this week, John Papa has on Tim Heuer who has always been out there pushing media... and he's talking about SMF or Silverlight Media Framework for the uninitiated, and also extending it. Silverlight Tip of the Day #7 – Localized Resources Mike Snow has Tip Number 7 up and it's about localization... good end-to-end discussion and demonstration. Just thought I should use that to prove to my daughter that the tatoo she had put on the back of her neck actually reads "Eat More Broccoli" :) Silverlight Tip of the Day #8 – Detecting Alt, Shift, Control, Window & Apple Keys Combinations I just realized Mike Snow's site logo reads "Silverlight Tips of the Day" (bolding mine) ... that answers why I'm seeing more than one -- sorry Mike, couldn't pass it up :) ... Mike's second tip today and number 8 in the series is on detecting all the mouse button and ctl/alt/shift combinations in Silverlight. nRoute: More Wholesomeness, with SL 4 and .NET 4.0 Rishi has a post up announcing a new nRoute release for Silverlight 4 and .NET 4.0 He's tweaked the code to take advantages of enhancements in the new platforms, so check it out. Windows Phone 7 Developer Tools April 2010 Refresh Booya... Tim Heuer announced the release of the next drop in the WP7 tools ... dang wish I was at home today :) ... be sure to read the post for info such as the notes about Authenticode Assemblies and the release notes. Updates to Silverlight Multi-binding support Stefan Olson points up a SL4 change to Multi-binding support that he had previously blogged about. He shows the previous non-working example, and what you have to do to make it work now. Using XAML to create a custom wallpaper image for your mobile device David Anson has a solution for those pesky lost devices, and let me go on the record right now saying if anyone finds a WP7 phone laying around, just call me, it's mine :) [think that'd work??] ... ok, David's solution is a WPF app "MobileDeviceHomeScreenMaker" that you get the info set and it produces a png you then put on your device. But seriously about that lost phone... Stay in the 'Light!

• Tool to convert blogger.com content to dasBlog

  - by Daniel Moth

  Due to blogger.com dropping FTP support, I've had to move my blog. If you are in a similar situation, this post will help you by showing you the necessary steps to take. Goals No loss on blog posts, comments AND all existing permalinks continue to work (redirect to the correct place). Steps Download the XML files corresponding to your blogger.com content and store them in a folder. Install and configure dasBlog on your local machine. Configure your web.config file (will need updating once you run step 4). Use the tool I describe further down to generate the content and place it at the right place. Test your site locally. Once you are happy, repeat step 2 on your hosting provider of choice. Remember to copy up your dasBlog theme folder if you created one. Copy up the local web.config file and the XML dasBlog content files generated by the tool of step 4. Test your site on the server. Once you are happy, go live (following instructions from your hoster). In my case, I gave the nameservers from my new hoster to my existing domain registrar and they made the switch. Tool (code) At step 4 above I referred to a tool. That is an overstatement, it is simply one 450-line C#code file that you can download here: BloggerToDasBlog.cs. I used this from a .NET 2.0 console app (and I run it under the Visual Studio debugger, i.e. F5) like this: Program.cs. The console app referenced the dasBlog 2.3 ASP.NET Blogging Engine i.e. the newtelligence.DasBlog.Runtime.dll assembly. Let me describe what the code does: Input: A path to a folder where the XML files from the old blogger.com blog reside. It can deal with both types of XML file. A full file path to a file where it creates XML redirect input (as required by the rewriteMap mentioned here). The blog URL. The author's email. The blog author name. A path to an empty folder where the new XML dasBlog content files will get created. The subfolder name used after the domain name in the URL. The 3 reg ex patterns to use. You can use the same as mine, but will need to tweak the monthly_archive rule. Again, to see what values I passed for all the above, see my Program.cs file. Output: It creates dasBlog XML files in the folder specified. It creates those by parsing the old blogger.com XML files that reside in the folder specified. After that is generated, copy it to the "Content" folder under your dasBlog installation. It creates an XML file with a single ignorable root element and a bunch of inner XML elements. You can copy paste these in the web.config file as discussed in this post. Other notes: For each blog post, it detects outgoing links to itself (i.e. to the same blog), and rewrites those to point to the new URLs. So internal links do not rely on the web.config redirects. It deals with duplicate post titles; it does not deal with triplicates and higher. Removes all references to blogger.com (e.g. references to [email protected], the injected hidden footer for statistics that each blog post has and others – see the code). It creates a lot of diagnostic output (in the Output window) and indeed the documentation for the code is in the Debug.WriteLine statements ;) This is not code I will maintain or support – it was a throwaway one-use project that I am sharing here as a starting point for anyone finding themselves in the same boat that I was. Enjoy "as is". Comments about this post welcome at the original blog.

• Java Resources for Windows Azure

  - by BuckWoody

  Windows Azure is a Platform as a Service – a PaaS – that runs code you write. That code doesn’t just mean the languages on the .NET platform – you can run code from multiple languages, including Java. In fact, you can develop for Windows and SQL Azure using not only Visual Studio but the Eclipse Integrated Development Environment (IDE) as well.  Although not an exhaustive list, here are several links that deal with Java and Windows Azure: Resource Link Windows Azure Java Development Center http://www.windowsazure.com/en-us/develop/java/  Java Development Guidance http://msdn.microsoft.com/en-us/library/hh690943(VS.103).aspx  Running a Java Environment on Windows Azure http://blogs.technet.com/b/port25/archive/2010/10/28/running-a-java-environment-on-windows-azure.aspx  Running a Java Environment on Windows Azure http://blogs.technet.com/b/port25/archive/2010/10/28/running-a-java-environment-on-windows-azure.aspx  Run Java with Jetty in Windows Azure http://blogs.msdn.com/b/dachou/archive/2010/03/21/run-java-with-jetty-in-windows-azure.aspx  Using the plugin for Eclipse http://blogs.msdn.com/b/craig/archive/2011/03/22/new-plugin-for-eclipse-to-get-java-developers-off-the-ground-with-windows-azure.aspx  Run Java with GlassFish in Windows Azure http://blogs.msdn.com/b/dachou/archive/2011/01/17/run-java-with-glassfish-in-windows-azure.aspx  Improving experience for Java developers with Windows  Azure http://blogs.msdn.com/b/interoperability/archive/2011/02/23/improving-experience-for-java-developers-with-windows-azure.aspx  Java Access to SQL Azure via the JDBC Driver for SQL  Server http://blogs.msdn.com/b/brian_swan/archive/2011/03/29/java-access-to-sql-azure-via-the-jdbc-driver-for-sql-server.aspx  How to Get Started with Java, Tomcat on Windows Azure http://blogs.msdn.com/b/usisvde/archive/2011/03/04/how-to-get-started-with-java-tomcat-on-windows-azure.aspx  Deploying Java Applications in Azure http://blogs.msdn.com/b/mariok/archive/2011/01/05/deploying-java-applications-in-azure.aspx  Using the Windows Azure Storage Explorer in Eclipse http://blogs.msdn.com/b/brian_swan/archive/2011/01/11/using-the-windows-azure-storage-explorer-in-eclipse.aspx  Windows Azure Tomcat Solution Accelerator http://archive.msdn.microsoft.com/winazuretomcat  Deploying a Java application to Windows Azure with  Command-line Ant http://java.interoperabilitybridges.com/articles/deploying-a-java-application-to-windows-azure-with-command-line-ant  Video: Open in the Cloud: Windows Azure and Java http://channel9.msdn.com/Events/PDC/PDC10/CS10  AzureRunMe  http://azurerunme.codeplex.com/  Windows Azure SDK for Java http://www.interoperabilitybridges.com/projects/windows-azure-sdk-for-java  AppFabric SDK for Java http://www.interoperabilitybridges.com/projects/azure-java-sdk-for-net-services  Information Cards for Java http://www.interoperabilitybridges.com/projects/information-card-for-java  Apache Stonehenge http://www.interoperabilitybridges.com/projects/apache-stonehenge  Channel 9 Case Study on Java and Windows Azure http://www.microsoft.com/casestudies/Windows-Azure/Gigaspaces/Solution-Provider-Streamlines-Java-Application-Deployment-in-the-Cloud/400000000081

• Christian Radio Locator iPhone app

  - by Tim Hibbard

  For the last three months or so I've been working on an iPhone (and iPad) app in my spare time. It all started when I took the kids to Minneapolis and had a hard time finding radio stations to listen to on the trip. I looked in the App Store for an app that would use my GPS to show me Christian radio stations nearby, but there wasn't one. So I decided to build my own. Using public information from the FCC and a few other sources, I built a database in Google docs that contains the frequency for all Christian radio stations, where the tower is located and how far the tower can reach. I also included any streaming audio information and other contact information like Facebook or Twitter that I could find. Google spreadsheets publish in JSON format (yes, really) and Xcode can automatically deserialize JSON into a properly formatted entity. This is one area that Xcode is far superior to C#. In a just a few lines of code, I can have a list of in-memory strongly typed objects from a web-based JSON feed. To accomplish the same thing natively in .NET would be much more work and wouldn't feel nearly as clean when it was said and done. The snazzy icon shown above was built by my very talented wife. She hasn't yet provided any feedback on the app's user interface, which is why it is so plain and boring. I used a navigation view controller and EGO pull to refresh table view to construct the main window. Pulling down to refresh initiates a GPS lookup, which queries the database for radio stations in range (yes, you can pass parameters to Google spreadsheets and get a subset back in JSON). Pulling up on the table extends the range of the search and includes stations that may not be close enough to get clear audio. This feature is not that intuitive and the next version contains an update to that functionality. Tapping a cell will show a detail view that displays additional information about the station. The user can click to view the station on a map, click to listen to an online stream (if available) or click to see the station's Facebook or Twitter pages. Swiping back and forth on the table changes the information that is displayed on the right hand side of the table cell. It scrolls through the city where the tower is located, how far the phone is from the tower, the range of the tower and in the next version a signal strength indicator. This was pretty easy to implement once I figured out how to assign the gesture recognizer delegate.  Tapping and holding on a cell will jump the user to the map view screen. Which is pretty cool, but very hard for even a power user to discover. To tackle the issue of discoverability, the next version has a series of instructions displayed at the bottom of the screen to show the user the various shortcuts. Once the user has performed the swipes and long holds, the instructions disappear. I've learned a lot developing this app. Spending over a decade exclusively in .NET made the learning curve a bit steep, but once I learned the structure and syntax of Objective-C, I've learned to appreciate the power and simplicity of it. Here are a few screenshots. I would really appreciate any feedback and especially iTunes reviews. Technically it is open source and a smart googler could probably find it. I just haven't promoted it as open source.     Cross posted from timhibbard.com

• Having Fun with Coding4Fun&rsquo;s Windows Phone 7 Controls

  - by mbcrump

  I’m a big believer in having a hobby project as you can probably tell from the first sentence in my “personal webpage using Silverlight” article. One of my current hobby projects is to re-do my current WP7 application in the marketplace. I knew up front that I needed a “Loading” animation and a better “About” box. After starting to develop my own, I noticed a great set of WP7 controls by Coding4Fun and decided to use them in my new application. Before I go any further they are FREE and Open-Source. It is really simple to get started, just go to the CodePlex site and click the download button. After you have downloaded it then extract it to a Folder and you will have 4 DLL files. They are listed below: Now create a Windows Phone 7 Project and add references to the DLL’s by right clicking on the References folder and clicking “Add references”.   After adding the references, we can get started. I needed a ProgressOverlay animation or “Loading Screen” while my RSS feed is downloading. Basically, you just need to add the following namespace to whatever page you want the control on: xmlns:Controls="clr-namespace:Coding4Fun.Phone.Controls;assembly=Coding4Fun.Phone.Controls" And then the code inside your Grid or wherever you want the Loading screen placed. <Controls:ProgressOverlay Name="progressOverlay" > <Controls:ProgressOverlay.Content> <TextBlock>Loading</TextBlock> </Controls:ProgressOverlay.Content> </Controls:ProgressOverlay> Bam, you now have a great looking loading screen. Of course inside the ProgressOverlay, you may want to add a Visibility property to turn it off after your data loads if you are using MVVM or similar pattern.   Next up, I needed a nice clean “About Box” that looks good but is also functional. Meaning, if they click on my twitter name, web or email to launch the appropriate task. Again, this is only a few lines of code: var p = new AboutPrompt(); p.VersionNumber = "2.0"; p.Show("Michael Crump", "@mbcrump", "michael@michaelcrump.net", @"http://michaelcrump.net"); A nice clean “About” box with just a few lines of code! I’m all for code that I don’t have to write. It also comes with a pretty sweet InputPrompt for grabbing info from a user: The code for this is also very simple: InputPrompt input = new InputPrompt(); input.Completed += (s, e) => { MessageBox.Show(e.Result.ToString()); }; input.Title = "Input Box"; input.Message = "What does a \"Developer Large\" T-Shirt Mean? "; input.Show(); I also enjoyed the PhoneHelper that allows you to get data out of the WMAppManifest File very easy. So for example if I wanted the Version info from the WMAppManifest file. I could write one line and get it. PhoneHelper.GetAppAttribute("Version") Of course you would want to make sure you add the following using statement: using Coding4Fun.Phone.Controls.Data; You can’t have all these cool controls without a great set of Converters. The included BooleanToVisibility converter will convert a Boolean to and from a Visibility value. This is excellent when using something like a CheckBox to display a TextBox when its checked. See the example below: The code is below: <phone:PhoneApplicationPage.Resources> <Converters:BooleanToVisibilityConverter x:Key="BooleanToVisibilityConverter"/> </phone:PhoneApplicationPage.Resources> <CheckBox x:Name="checkBox"/> <TextBlock Text="Display Text" Visibility="{Binding ElementName=checkBox, Path=IsChecked, Converter={StaticResource BooleanToVisibilityConverter} }"/> That’s not all the goodies included. They also provide a RoundedButton, TimePicker and several other converters. The documentation is great and I would recommend you give them a shot if you need any of this functionality. Btw, thank Brian Peek for his awesome work on Coding4Fun!  Subscribe to my feed

• Knockout.js - Filtering, Sorting, and Paging

  - by jtimperley

  Originally posted on: http://geekswithblogs.net/jtimperley/archive/2013/07/28/knockout.js---filtering-sorting-and-paging.aspxKnockout.js is fantastic! Maybe I missed it but it appears to be missing flexible filtering, sorting, and pagination of its grids. This is a summary of my attempt at creating this functionality which has been working out amazingly well for my purposes. Before you continue, this post is not intended to teach you the basics of Knockout. They have already created a fantastic tutorial for this purpose. You'd be wise to review this before you continue. http://learn.knockoutjs.com/ Please view the full source code and functional example on jsFiddle. Below you will find a brief explanation of some of the components. http://jsfiddle.net/JTimperley/pyCTN/13/ First we need to create a model to represent our records. This model is a simple container with defined and guaranteed members. function CustomerModel(data) { if (!data) { data = {}; } var self = this; self.id = data.id; self.name = data.name; self.status = data.status; } Next we need a model to represent the page as a whole with an array of the previously defined records. I have intentionally overlooked the filtering and sorting options for now. Note how the filtering, sorting, and pagination are chained together to accomplish all three goals. This strategy allows each of these pieces to be used selectively based on the page's needs. If you only need sorting, just sort, etc. function CustomerPageModel(data) { if (!data) { data = {}; } var self = this; self.customers = ExtractModels(self, data.customers, CustomerModel); var filters = […]; var sortOptions = […]; self.filter = new FilterModel(filters, self.customers); self.sorter = new SorterModel(sortOptions, self.filter.filteredRecords); self.pager = new PagerModel(self.sorter.orderedRecords); } The code currently supports text box and drop down filters. Text box filters require defining the current 'Value' and the 'RecordValue' function to retrieve the filterable value from the provided record. Drop downs allow defining all possible values, the current option, and the 'RecordValue' as before. Once defining these filters, they are automatically added to the screen and any changes to their values will automatically update the results, causing their sort and pagination to be re-evaluated. var filters = [ { Type: "text", Name: "Name", Value: ko.observable(""), RecordValue: function(record) { return record.name; } }, { Type: "select", Name: "Status", Options: [ GetOption("All", "All", null), GetOption("New", "New", true), GetOption("Recently Modified", "Recently Modified", false) ], CurrentOption: ko.observable(), RecordValue: function(record) { return record.status; } } ]; Sort options are more simplistic and are also automatically added to the screen. Simply provide each option's name and value for the sort drop down as well as function to allow defining how the records are compared. This mechanism can easily be adapted for using table headers as the sort triggers. That strategy hasn't crossed my functionality needs at this point. var sortOptions = [ { Name: "Name", Value: "Name", Sort: function(left, right) { return CompareCaseInsensitive(left.name, right.name); } } ]; Paging options are completely contained by the pager model. Because we will be chaining arrays between our filtering, sorting, and pagination models, the following utility method is used to prevent errors when handing an observable array to another observable array. function GetObservableArray(array) { if (typeof(array) == 'function') { return array; }   return ko.observableArray(array); }

• Creando un File Upload

  - by jaullo

  Para iniciar hablaremos un poco sobre el control File Upload, de esta forma daremos una idea general de que es y como trabaja. El File Upload es un control de asp.net que permite que los usuarios seleccionen un archivo de cualquier ubicación en el equipo y lo suban a un directorio predeterminado a traves de una página asp.net. En principio este control esta limitado para no permitir subir archivos de mas de 4 MB. Sin embargo, desde el webconfig de nuestra aplicacón podremos cambiar ese valor, ya sea para aumentarlo o bien para disminuirlo. Nuestro ejemplo, se enfocará en crear un webcontrol que permita seleccionar un archivo y guardarlo, asi que empecemos. Lo primero será agregar a nuestra página un webcontrol que llamaremos Upload.ascx Posteriormente en nuestro webcontrol, agregamos el siguiente código: <table style="width: 100%">         <tr>             <td colspan="3">             <div align="center">                  <asp:Label ID="Label1" runat="server" Text="File Upload"></asp:Label>              </div>             </td>                    </tr>         <tr>             <td style="width: 456px" rowspan="2">                                                             &nbsp;</td>             <td style="width: 386px">                                <div align="center">                         <asp:FileUpload ID="FileUpload1" runat="server" Height="24px" Width="243px" />                         <span id="Span1" runat="server" />                            </div>                      </td>             <td rowspan="2">                                                             </td>         </tr>         <tr>             <td style="width: 386px">                 <div align="center">                      <asp:ImageButton Id="btnupload" runat="server" OnClick="btnupload_Click"                     ImageUrl="~/Styles/img/upload.png" style="text-align: center" />           </div>                  </td>         </tr>         <tr>             <td colspan="3">                 &nbsp;</td>         </tr>     </table>  De esta forma nuestro control deberá verse algo así   Por último en el code behin de nuestro control agregamos el código a nuestro boton, el cual será el encargado de leer el archivo que se encuentra en el File Upload y guardarlo en la ruta especificada.  Protected Sub btnupload_Click(ByVal sender As Object, ByVal e As System.Web.UI.ImageClickEventArgs) Handles btnupload.Click         If FileUpload1.HasFile Then             Dim fileExt As String             fileExt = System.IO.Path.GetExtension(FileUpload1.FileName)             If (fileExt = ".exe") Then                 Label1.Text = "You can´t upload .exe file!"             Else                 Try                     FileUpload1.SaveAs(decrpath & _                        FileUpload1.FileName)                     Label1.Text = "File name: " & _                       FileUpload1.PostedFile.FileName & "<br>" & _                       "File Size: " & _                       FileUpload1.PostedFile.ContentLength & " kb<br>" & _                       "Content type: " & _                       FileUpload1.PostedFile.ContentType                 Catch ex As Exception                     Label1.Text = "ERROR: " & ex.Message.ToString()                 End Try             End If         Else             Label1.Text = "You have not specified a file!"         End If            End Sub   Como vemos en el código anterior tambien hemos agregado otros elementos los cuales nos dirán el nombre del archivo, el tipo de contenido y el tamaño en kb una vez que el archivo ha sido súbido al servidor. Por último deben tomar en cuenta que decrpath es la ruta en donde será subido el archivo, la cual deben variar a su gusto.

• Building a Mafia&hellip;TechFest Style

  - by David Hoerster

  It’s been a few months since I last blogged (not that I blog much to begin with), but things have been busy.  We all have a lot going on in our lives, but I’ve had one item that has taken up a surprising amount of time – Pittsburgh TechFest 2012.  After the event, I went through some minutes of the first meetings for TechFest, and I started to think about how it all came together.  I think what inspired me the most about TechFest was how people from various technical communities were able to come together and build and promote a common event.  As a result, I wanted to blog about this to show that people from different communities can work together to build something that benefits all communities.  (Hopefully I've got all my facts straight.)  TechFest started as an idea Eric Kepes and myself had when we were planning our next Pittsburgh Code Camp, probably in the summer of 2011.  Our Spring 2011 Code Camp was a little different because we had a great infusion of some folks from the Pittsburgh Agile group (especially with a few speakers from LeanDog).  The line-up was great, but we felt our audience wasn’t as broad as it should have been.  We thought it would be great to somehow attract other user groups around town and have a big, polyglot conference. We started contacting leaders from Pittsburgh’s various user groups.  Eric and I split up the ones that we knew about, and we just started making contacts.  Most of the people we started contacting never heard of us, nor we them.  But we all had one thing in common – we ran user groups who’s primary goal is educating our members to make them better at what they do. Amazingly, and I say this because I wasn’t sure what to expect, we started getting some interest from the various leaders.  One leader, Greg Akins, is, in my opinion, Pittsburgh’s poster boy for the polyglot programmer.  He’s helped us in the past with .NET Code Camps, is a Java developer (and leader in Pittsburgh’s Java User Group), works with Ruby and I’m sure a handful of other languages.  He helped make some e-introductions to other user group leaders, and the whole thing just started to snowball. Once we realized we had enough interest with the user group leaders, we decided to not have a Fall Code Camp and instead focus on this new entity. Flash-forward to October of 2011.  I set up a meeting, with the help of Jeremy Jarrell (Pittsburgh Agile leader) to hold a meeting with the leaders of many of Pittsburgh technical user groups.  We had representatives from 12 technical user groups (Python, JavaScript, Clojure, Ruby, PittAgile, jQuery, PHP, Perl, SQL, .NET, Java and PowerShell) – 14 people.  We likened it to a scene from a Godfather movie where the heads of all the families come together to make some deal.  As a result, the name “TechFest Mafia” was born and kind of stuck. Over the next 7 months or so, we had our starts and stops.  There were moments where I thought this event would not happen either because we wouldn’t have the right mix of topics (was I off there!), or enough people register (OK, I was wrong there, too!) or find an appropriate venue (hmm…wrong there, too) or find enough sponsors to help support the event (wow…not doing so well).  Overall, everything fell into place with a lot of hard work from Eric, Jen, Greg, Jeremy, Sean, Nicholas, Gina and probably a few others that I’m forgetting.  We also had a bit of luck, too.  But in the end, the passion that we had to put together an event that was really about making ourselves better at what we do really paid off. I’ve never been more excited about a project coming together than I have been with Pittsburgh TechFest 2012.  From the moment the first person arrived at the event to the final minutes of my closing remarks (where I almost lost my voice – I ended up being diagnosed with bronchitis the next day!), it was an awesome event.  I’m glad to have been part of bringing something like this to Pittsburgh…and I’m looking forward to Pittsburgh TechFest 2013.  See you there!

• Web.config WordPress rewrite rules next to Magento

  - by Flo

  I've installed Magento on IIS in folder: E:\mydomain\wwwroot (I already have it all running correctly). I have no deeper folder magento, I placed all files directly in the wwwroot folder, so: wwwroot\app wwwroot\downloader wwwroot\errors wwwroot\includes etc... UPDATE: since I'm on IIS my .htaccess is ignored completely and my web.config rules are used instead. Here's my web.config in folder e:\mydomain\wwwroot: <?xml version="1.0" encoding="UTF-8"?> <configuration> <system.webServer> <rewrite> <rules> <rule name="Magento SEO: remove index.php from URL"> <match url="^(?!index.php)([^?#]*)(\\?([^#]*))?(#(.*))?" /> <conditions> <add input="{URL}" pattern="^/(media|skin|js)/" ignoreCase="false" negate="true" /> <add input="{REQUEST_FILENAME}" matchType="IsFile" ignoreCase="false" negate="true" /> <add input="{REQUEST_FILENAME}" matchType="IsDirectory" ignoreCase="false" negate="true" /> </conditions> <action type="Rewrite" url="index.php/{R:0}" /> </rule> </rules> </rewrite> </system.webServer> </configuration> Next, I wanted to install WordPress. I unzipped all files in folder e:\mydomain\wwwroot\wordpress Browsed to www.mydomain.com/wordpress/wp-admin/install.php, where I configured everything for my database. Everything was installed correctly. I then navigate to http://www.mydomain.com/wordpress/wp-login.php where I type my credentials. I seem to be logged in and am redirected to http://www.mydomain.com/wordpress/wp-admin/ But there I receive an empty page. I enabled detailed error message in IIS following this article: http://www.iis.net/learn/troubleshoot/diagnosing-http-errors/how-to-use-http-detailed-errors-in-iis I also checkec with Fiddler and see that I receive a 500 error: GET /wordpress/wp-admin/ HTTP/1.1 Host: www.mydomain.com Connection: keep-alive Cache-Control: max-age=0 Accept: text/html,application/xhtml+xml,application/xml;q=0.9,/;q=0.8 User-Agent: Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/29.0.1547.76 Safari/537.36 Referer: http://www.mydomain.com/wordpress/wp-login.php Accept-Encoding: gzip,deflate,sdch Accept-Language: en-US,en;q=0.8,nl;q=0.6 Cookie: wordpress_fabec4083cf12d8de89c98e8aef4b7e3=floran%7C1381236774%7C2d8edb4fc6618f290fadb49b035cad31; wordpress_test_cookie=WP+Cookie+check; wordpress_logged_in_fabec4083cf12d8de89c98e8aef4b7e3=floran%7C1381236774%7Cbf822163926b8b8df16d0f1fefb6e02e HTTP/1.1 500 Internal Server Error Content-Type: text/html Server: Microsoft-IIS/7.5 X-Powered-By: PHP/5.4.14 X-Powered-By: ASP.NET Date: Sun, 06 Oct 2013 12:56:03 GMT Content-Length: 0 My WordPress web.config in folder e:\mydomain\wwwroot\wordpress contains: <?xml version="1.0" encoding="UTF-8"?> <configuration> <system.webServer> <rewrite> <rules> <rule name="wordpress" patternSyntax="Wildcard"> <match url="*"/> <conditions> <add input="{REQUEST_FILENAME}" matchType="IsFile" negate="true"/> <add input="{REQUEST_FILENAME}" matchType="IsDirectory" negate="true"/> </conditions> <action type="Rewrite" url="index.php"/> </rule></rules> </rewrite> </system.webServer> </configuration> I also want my WordPress articles to be available on www.mydomain.com/blog instead of www.mydomain.com/wordpress Ofcourse my admin links for Magento and Wordpress should also work.

• From NaN to Infinity...and Beyond!

  - by Tony Davis

  It is hard to believe that it was once possible to corrupt a SQL Server Database by storing perfectly normal data values into a table; but it is true. In SQL Server 2000 and before, one could inadvertently load invalid data values into certain data types via RPC calls or bulk insert methods rather than DML. In the particular case of the FLOAT data type, this meant that common 'special values' for this type, namely NaN (not-a-number) and +/- infinity, could be quite happily plugged into the database from an application and stored as 'out-of-range' values. This was like a time-bomb. When one then tried to query this data; the values were unsupported and so data pages containing them were flagged as being corrupt. Any query that needed to read a column containing the special value could fail or return unpredictable results. Microsoft even had to issue a hotfix to deal with failures in the automatic recovery process, caused by the presence of these NaN values, which rendered the whole database inaccessible! This problem is history for those of us on more current versions of SQL Server, but its ghost still haunts us. Recently, for example, a developer on Red Gate’s SQL Response team reported a strange problem when attempting to load historical monitoring data into a SQL Server 2005 database via the C# ADO.NET provider. The ratios used in some of their reporting calculations occasionally threw out NaN or infinity values, and the subsequent attempts to load these values resulted in a nasty error. It turns out to be a different manifestation of the same problem. SQL Server 2005 still does not fully support the IEEE 754 standard for floating point numbers, in that the FLOAT data type still cannot handle NaN or infinity values. Instead, they just added validation checks that prevent the 'invalid' values from being loaded in the first place. For people migrating from SQL Server 2000 databases that contained out-of-range FLOAT (or DATETIME etc.) data, to SQL Server 2005, Microsoft have added to the latter's version of the DBCC CHECKDB (or CHECKTABLE) command a DATA_PURITY clause. When enabled, this will seek out the corrupt data, but won’t fix it. You have to do this yourself in what can often be a slow, painful manual process. Our development team, after a quizzical shrug of the shoulders, simply decided to represent NaN and infinity values as NULL, and move on, accepting the minor inconvenience of not being able to tell them apart. However, what of scientific, engineering and other applications that really would like the luxury of being able to both store and access these perfectly-reasonable floating point data values? The sticking point seems to be the stipulation in the IEEE 754 standard that, when NaN is compared to any other value including itself, the answer is "unequal" (i.e. FALSE). This is clearly different from normal number comparisons and has repercussions for such things as indexing operations. Even so, this hardly applies to infinity values, which are single definite values. In fact, there is some encouraging talk in the Connect note on this issue that they might be supported 'in the SQL Server 2008 timeframe'. If didn't happen; SQL 2008 doesn't support NaN or infinity values, though one could be forgiven for thinking otherwise, based on the MSDN documentation for the FLOAT type, which states that "The behavior of float and real follows the IEEE 754 specification on approximate numeric data types". However, the truth is revealed in the XPath documentation, which states that "…float (53) is not exactly IEEE 754. For example, neither NaN (Not-a-Number) nor infinity is used…". Is it really so hard to fix this problem the right way, and properly support in SQL Server the IEEE 754 standard for the floating point data type, NaNs, infinities and all? Oracle seems to have managed it quite nicely with its BINARY_FLOAT and BINARY_DOUBLE types, so it is technically possible. We have an enterprise-class database that is marketed as being part of an 'integrated' Windows platform. Absurdly, we have .NET and XPath libraries that fully support the standard for floating point numbers, and we can't even properly store these values, let alone query them, in the SQL Server database! Cheers, Tony.

• WEB203 &ndash; Jump into Silverlight!&hellip; and Become Effective Immediately with Tim Huckaby, Fou

  - by Robert Burger

  Getting ready for the good stuff. Definitely wish there were more Silverlight and WCF RIA sessions, but this is a start.  Was lucky to get a coveted power-enabled seat.  Luckily, due to my trustily slow Verizon data card, I can get these notes out amidst a total Internet outage here.  This is the second breakout session of the day, and is by far standing-room only.  I stepped out before the session started to get a cool Diet COKE and wouldn’t have gotten back in if I didn’t already have a seat. Tim says this is an intro session and that he’s been begging for intro sessions at TechEd for years and that by looking at this audience, he thinks the demand is there.  Admittedly, I didn’t know this was an intro session, or I might have gone elsewhere.  But, it was the very first Silverlight session, so I had to be here. Tim says he will be providing a very good comprehensive reference application at the end of the presentation.  He has just demoed it, and it is a full CRUD-based Sales Manager application based on…  AdventureWorks! Session Agenda What it is / How to get started Declarative Programming Layout and Controls, Events and Commands Working with Data Adding Style to Your Application   Silverlight…  “WPF Light” Why is the download 4.2MB?  Because the direct competitor is a 4.2MB download.  There is no technical reason it is not the entire framework.  It is purely to “be competitive”.   Getting Started Get all of the following downloads from www.silverlight.net/getstarted Install VS2010 or Visual Web Developer Express 2010 Install Silverlight 4 Tools for VS2010 Install Expression Blend 4 Install the Silverlight 4 Toolkit   Reference Application Features Uses MVVM pattern – a way to move data access code that would normally be inline within the UI and placing it in nice data access libraries Images loaded dynamically from the database, converting GIF to PNG because Silverlight does not support GIF. LINQ to SQL is the data access model WCF is the data provider and is using binary message encoding   Declarative Programming XAML replaces code for UI representation Attributes control Layout and Style Event handlers wired-up in XAML Declarative Data Binding   Layout Overview Content rendering flows inside of parent Fixed positioning (Canvas) is seldom used Panels are used to house content Margins and Padding over fixed size   Panels StackPanel – Arranges child elements into a single line oriented horizontally or vertically Grid – A flexible grid are that consists of rows and columns Canvas – An are where positions are specifically fixed WrapPanel (in Toolkit) – Positions child elements in sequential position left to right and top to bottom. DockPanel (in Toolkit) – Positions child controls within a dockable area   Positioning Horizontal and Vertical Alignment Margin – Separates an element from neighboring elements Padding – Enlarges the effective size of an element by a thickness   Controls Overview Not all controls created equal Silverlight, as a subset of WPF, so many WPF controls do not exist in the core Siverlight release Silverlight Toolkit continues to add controls, but are released in different quality bands Plenty of good 3rd party controls to fill the gaps Windows Phone 7 is to have 95% of controls available in Silverlight Core and Toolkit.   Events and Commands Standard .NET Events Routed Events Commands – based on the ICommand interface – logical action that can be invoked in several ways   Adding Style to Your Application Resource Dictionaries – Contains a hash table of key/value pairs.  Silverlight can only use Static Resources whereas WPF can also use Dynamic Resources Visual State Manager Silverlight 4 supports Implicit styles ResourceDictionary.MergedDictionaries combines many different file-based resources   Downloads

• Why is Apache ignoring VirtualHost directive for first name in hosts file?

  - by Peter Taylor

  Standard pre-emptive disclaimer: host names, IP addresses, and directories are anonymised. Problem We have a server with Apache 2.2 (WAMP) listening on one IP and IIS listening on another. An ASP.Net application running under IIS needs to do some simple GETs from the PHP applications running under Apache to build a unified search results page. This is a virtual server, so the internal IPs are mapped somehow to external ones. The internal DNS system doesn't resolve the publicly published names under which the applications are accessed externally, so the obvious solution was to add them to etc/hosts with the internal IP address: 127.0.0.1 localhost # 10.0.1.17 is the IP address Apache listens on 10.0.1.17 phpappone.example.com 10.0.1.17 phpapptwo.example.com After restarting Apache, phpappone.example.com stopped working. Instead of returning pages from that app, Apache was returning pages from the default site. The other PHP apps worked fine. Relevant configuration httpd.conf, summarised, says: ServerAdmin [email protected] ServerRoot "c:/server/Apache2" ServerName www.example.com Listen 10.0.1.17:80 Listen 10.0.1.17:443 # Not obviously related config options elided # Nothing obviously astandard # If you want more details, post a comment DocumentRoot "c:/server/Apache2/htdocs" <Directory /> Options FollowSymLinks AllowOverride None Order deny,allow Deny from all </Directory> # Fallback for unknown host names <Directory "c:/server/Apache2/htdocs"> Options Indexes FollowSymLinks AllowOverride None Order allow,deny Allow from all </Directory> # PHP apps common config <Directory "C:/Inetpub/wwwroot/phpapps"> Options FollowSymLinks -Indexes +ExecCGI AllowOverride All Order Allow,Deny Allow from All </Directory> # Virtual hosts NameVirtualHost 10.0.1.17:80 NameVirtualHost 10.0.1.17:443 <VirtualHost _default_:80> </VirtualHost> <VirtualHost _default_:443> SSLEngine On SSLCertificateFile "certs/example.crt" SSLCertificateKeyFile "certs/example.key" </VirtualHost> Include conf/vhosts/*.conf and the vhosts files are e.g. <VirtualHost 10.0.1.17:80> ServerName phpappone.example.com DocumentRoot "c:/Inetpub/wwwroot/phpapps/phpappone" </VirtualHost> <VirtualHost 10.0.1.17:443> ServerName phpappone.example.com DocumentRoot "c:/Inetpub/wwwroot/phpapps/phpappone" SSLEngine On SSLCertificateFile "certs/example.crt" SSLCertificateKeyFile "certs/example.key" </VirtualHost> Buggy behaviour or our misunderstanding? The documentation for name-based virtual hosts says that Now when a request arrives, the server will first check if it is using an IP address that matches the NameVirtualHost. If it is, then it will look at each <VirtualHost> section with a matching IP address and try to find one where the ServerName or ServerAlias matches the requested hostname. If it finds one, then it uses the configuration for that server. If no matching virtual host is found, then the first listed virtual host that matches the IP address will be used. Yet that isn't what we observe. It seems that if the hostname is the first hostname listed against the IP address in etc/hosts then it uses the configuration from the main server and skips the virtual host lookup. Workarounds The workaround we've put in place for the time being is to add a fake line to the hosts file: 127.0.0.1 localhost # 10.0.1.17 is the IP address Apache listens on 10.0.1.17 fakename.example.com 10.0.1.17 phpappone.example.com 10.0.1.17 phpapptwo.example.com This fixes the problem, but it's not very elegant. In addition, it seems a bit brittle: reordering lines in the hosts file (or deleting the nonsense value) can break it. The other obvious workaround is to make the main server configuration match that of the troublesome virtual host, but that is equally brittle. A third option, which is just ugly, would be to change the ASP.Net code to take separate config items for the IP address and the hostname and to implement HTTP manually. Ugh. The question Is there a good solution to this problem which localises any "Do not touch this!" explanations to the Apache config files?

• Hidden exceptions

  - by user12617285

  Occasionally you may find yourself in a Java application environment where exceptions in your code are being caught by the application framework and either silently swallowed or converted into a generic exception. Either way, the potentially useful details of your original exception are inaccessible. Wouldn't it be nice if there was a VM option that showed the stack trace for every exception thrown, whether or not it's caught? In fact, HotSpot includes such an option: -XX:+TraceExceptions. However, this option is only available in a debug build of HotSpot (search globals.hpp for TraceExceptions). And based on a quick skim of the HotSpot source code, this option only prints the exception class and message. A more useful capability would be to have the complete stack trace printed as well as the code location catching the exception. This is what the various TraceException* options in in Maxine do (and more). That said, there is a way to achieve a limited version of the same thing with a stock standard JVM. It involves the use of the -Xbootclasspath/p non-standard option. The trick is to modify the source of java.lang.Exception by inserting the following: private static final boolean logging = System.getProperty("TraceExceptions") != null; private void log() { if (logging && sun.misc.VM.isBooted()) { printStackTrace(); } } Then every constructor simply needs to be modified to call log() just before returning: public Exception(String message) { super(message); log(); } public Exception(String message, Throwable cause) { super(message, cause); log(); } // etc... You now need to compile the modified Exception.java source and prepend the resulting class to the boot class path as well as add -DTraceExceptions to your java command line. Here's a console session showing these steps: % mkdir boot % javac -d boot Exception.java % java -DTraceExceptions -Xbootclasspath/p:boot -cp com.oracle.max.vm/bin test.output.HelloWorld java.util.zip.ZipException: error in opening zip file at java.util.zip.ZipFile.open(Native Method) at java.util.zip.ZipFile.(ZipFile.java:127) at java.util.jar.JarFile.(JarFile.java:135) at java.util.jar.JarFile.(JarFile.java:72) at sun.misc.URLClassPath$JarLoader.getJarFile(URLClassPath.java:646) at sun.misc.URLClassPath$JarLoader.access$600(URLClassPath.java:540) at sun.misc.URLClassPath$JarLoader$1.run(URLClassPath.java:607) at java.security.AccessController.doPrivileged(Native Method) at sun.misc.URLClassPath$JarLoader.ensureOpen(URLClassPath.java:599) at sun.misc.URLClassPath$JarLoader.(URLClassPath.java:583) at sun.misc.URLClassPath$3.run(URLClassPath.java:333) at java.security.AccessController.doPrivileged(Native Method) at sun.misc.URLClassPath.getLoader(URLClassPath.java:322) at sun.misc.URLClassPath.getLoader(URLClassPath.java:299) at sun.misc.URLClassPath.getResource(URLClassPath.java:168) at java.net.URLClassLoader$1.run(URLClassLoader.java:194) at java.security.AccessController.doPrivileged(Native Method) at java.net.URLClassLoader.findClass(URLClassLoader.java:190) at sun.misc.Launcher$ExtClassLoader.findClass(Launcher.java:229) at java.lang.ClassLoader.loadClass(ClassLoader.java:306) at java.lang.ClassLoader.loadClass(ClassLoader.java:295) at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:301) at java.lang.ClassLoader.loadClass(ClassLoader.java:247) java.security.PrivilegedActionException at java.security.AccessController.doPrivileged(Native Method) at sun.misc.URLClassPath$JarLoader.ensureOpen(URLClassPath.java:599) at sun.misc.URLClassPath$JarLoader.(URLClassPath.java:583) at sun.misc.URLClassPath$3.run(URLClassPath.java:333) at java.security.AccessController.doPrivileged(Native Method) at sun.misc.URLClassPath.getLoader(URLClassPath.java:322) ... It's worth pointing out that this is not as useful as direct VM support for tracing exceptions. It has (at least) the following limitations: The trace is shown for every exception, whether it is thrown or not. It only applies to subclasses of java.lang.Exception as there appears to be bootstrap issues when the modification is applied to Throwable.java. It does not show you where the exception was caught. It involves overriding a class in rt.jar, something should never be done in a non-development environment.

• Building a Data Mart with Pentaho Data Integration Video Review by Diethard Steiner, Packt Publishing

  Originally posted on: http://geekswithblogs.net/Compudicted/archive/2014/06/01/building-a-data-mart-with-pentaho-data-integration-video-review-again.aspx The Building a Data Mart with Pentaho Data Integration Video by Diethard Steiner from Packt Publishing is more than just a course on how to use Pentaho Data Integration, it also implements and uses the principals of the Data Warehousing (and I even heard the name of Ralph Kimball in the video). Indeed, a video watcher should be familiar with its concepts as the Star Schema, Slowly Changing Dimension types, etc. so I suggest prior to watching this course to consider skimming through the Data Warehouse concepts (if unfamiliar) or even better, read the excellent Ralph’s The Data Warehouse Tooolkit. By the way, the author expands beyond using Pentaho along to MySQL and MonetDB which is a real icing on the cake! Indeed, I even suggest the name of the course should be ‘Building a Data Warehouse with Pentaho’. To successfully complete the course one needs to know some Linux (Ubuntu used in the course), the VI editor and the Bash command shell, but it seems that similar requirements would also apply to the Windows OS. Additionally, knowing some basic SQL would not hurt. As I had said, MonetDB is used in this course several times which seems to be not anymore complex than say MySQL, but based on what I read is very well suited for fast querying big volumes of data thanks to having a columnstore (vertical data storage). I don’t see what else can be a barrier, the material is very digestible. On this note, I must add that the author does not cover how to acquire the software, so here is what I found may help: Pentaho: the free Community Edition must be more than anyone needs to learn it. Or even go into a POC. MonetDB can be downloaded (exists for both, Linux and Windows) from http://goo.gl/FYxMy0 (just see the appropriate link on the left). The author seems to be using Eclipse to run SQL code, one can get it from http://goo.gl/5CcuN. To create, or edit database entities and/or schema otherwise one can use a universal tool called SQuirreL, get it from http://squirrel-sql.sourceforge.net.   Next, I must confess Diethard is very knowledgeable in what he does and beyond. However, there will be some accent heard to the user of the course especially if one’s mother tongue language is English, but it I got over it in a few chapters. I liked the rate at which the material is being presented, it makes me feel I paid for every second Eventually, my impressions are: Pentaho is an awesome ETL offering, it is worth learning it very much (I am an ETL fan and a heavy user of SSIS) MonetDB is nice, it tickles my fancy to know it more Data Warehousing, despite all the BigData tool offerings (Hive, Scoop, Pig on Hadoop), using the traditional tools still rocks Chapters 2 to 6 were the most fun to me with chapter 8 being the most difficult.   In terms of closing, I highly recommend this video to anyone who needs to grasp Pentaho concepts quick, likewise, the course is very well suited for any developer on a “supposed to be done yesterday” type of a project. It is for a beginner to intermediate level ETL/DW developer. But one would need to learn more on Data Warehousing and Pentaho, for such I recommend the 5 star Pentaho Data Integration 4 Cookbook. Enjoy it! Disclaimer: I received this video from the publisher for the purpose of a public review.
