  • Why bother writing an Windows 8 app?

    - by Dennis Vroegop
    So you want to know more about development for Window 8. Great! There are lots of reasons you should be excited about this. Since I don’t know why YOU are interested in this, I’ll make a list of reasons people can choose from. (as a side note: whenever I talk about Win8 development I am referring to the Metro Style / WinRt side of things. Apps for the ‘classic’ desktop side of Win8 on Intel are business as usual…) So… Why would you care about making an app for Windows 8? 1. It’s cool. Let’s not beat around the bush: if you like development for a hobby then you’ll love to work on this new platform. You can create apps in a relative short time (short time as in compared to writing a new CRM system) and that makes it great for a hobby product. 2. You’ll stand out. Hey, we all need an ego boost every now and then. We all need to feel special. So if you can manage to be one of the first to have you app in the Store then you’ll likely to be noticed. Just close your eyes for a moment and image you standing in a bar. It’s crowded, and then you casually say “Oh yeah, I just had my app certified and it’s in the Win8 store now”. People will stop talking, will offer you drinks and beautiful women / gorgeous man / furry creatures from Alpha Centauri (whatever your preferences are) will propose. Or maybe not. Anyway…. 3. Make some cash! IDC predicts there will be about 350,000,000 Windows 8 licenses sold in the next year. Think about that number. 350,000,000. And they all have access to the Store. Where you’re app will be. With one little click they can select it, download and somehow magically $1.00 or $2.00 from their bank account is transferred to yours. Now, I am not saying that all of those people will download and buy your app but what if only 1% of them did? Remember: there aren’t that many apps available yet….. 4. Learn. Creating new small apps is a great way to learn new stuff. Yes, you could read about it (on this blog for instance) but the only way to learn something is to do it. So be prepared for the future and learn something new by doing it.Write an app! Now! 5. The biggie (for me at least): it’s fun. Even if you remove the points above it’s still fun to write for these devices and this platform. Now some of you will say : “But why not write a great app for IOS or Android?” I think this is a valid question. Of course the novelty of the platform wears out and points 2 and 3 from above list will not be as relevant as it is today. But still 1 4 and 5 remain. And don’t forget: if you already work on the Microsoft platform it’s not that hard to learn this new Win8 stuff. If you have done some XAML development (be it WPF or Silverlight) you are almost there in becoming a good Win8 developer. So you’ll be more productive much sooner than when you have to learn Objective C or Java. Even if you’re a HTML / Javascript developer (I say developer here, not designer) you’ll be up to speed on Win8 development pretty soon. Yes, you, that funky Web Developer who lives and breathes HTML5, CSS3 and JavaScript / Node.Js / JQuery: you too can be a Win8 developer. A first class Win8 developer! So.. Download the stuff you need from http://dev.windows.com install Windows 8 and Visual Studio 12 and by the time you’re ready I’ll be working on the next article: how to do all this? Happy coding!

  • "Guiding" a Domain Expert to Retire from Programming

    - by James Kolpack
    I've got a friend who does IT at a local non-profit where they're using a custom web application which is no longer supported by the company who built it. (out of business, support was too expensive, I'm not sure...) Development on this app started around 10+ years ago so the technologies being harnessed are pretty out of date now - classic asp using vbscript and SQL Server 2000. The application domain is in the realm of government bookkeeping - so even though the development team is long gone, there are often new requirements of this software. Enter the... The domain expert. This is an middle aged accounting whiz without much (or any?) prior development experience. He studied the pages, code and queries and learned how to ape the style of the original team which, believe me, is mediocre at best. He's very clever and very tenacious but has no experience in software beyond what he's picked up from this app. Otherwise, he's a pleasant guy to talk to and definitely knows his domain. My friend in IT, and probably his superiors in the company, want him out of the code. They view him as wasting his expertise on coding tasks he shouldn't be doing. My friend got me involved with a few small contracts which I handled without much problem - other than somewhat of a communication barrier with the domain expert. He explained the requirements very quickly, assuming prior knowledge of the domain which I do not have. This is partially his normal style, and I think maybe a bit of resentment from my involvement. So, I think he feels like the owner of the code and has entrenched himself in a development position. So... his coding technique. One of his latest endeavors was to make a page that only he could reach (theoretically - the security model for the system is wretched) where he can enter a raw SQL query, run it, and save the query to run again later. A report that I worked on had been originally implemented by him using 6 distinct queries, 3 or 4 temp tables to coordinate the data between the queries, and the final result obtained by importing the data from the final query into Access and doing a pivot and some formatting. It worked - well, some of the results were incorrect - but at what a cost! (I implemented the report in a single query with at least 1/10th the amount of code.) He edits code in notepad. He doesn't seem to know about online reference material for the languages. I recently read an article on Dr. Dobbs titled "What Makes Bad Programmers Different" - and instantly thought of our domain expert. From the article: Their code is large, messy, and bug laden. They have very superficial knowledge of their problem domain and their tools. Their code has a lot of copy/paste and they have very little interest in techniques that reduce it. The fail to account for edge cases, while inefficiently dealing with the general case. They never have time to comment their code or break it into smaller pieces. Empirical evidence plays no little role in their decisions. 5.5 out of 6. My friend is wanting me to argue the case to their management - specifically, I got this email from their manager to respond to: ...Also, I need to talk to you about what effect there is from Domain Expert continuing to make edits to the live environment. If that is a problem for you I need to know so I can have his access blocked. Some examples would help. In my opinion, from a technical standpoint, it's dangerous to have him making changes without any oversight. On the other hand, I'm just doing one-off contracts at this point and don't have much desire to get involved deeply enough that I'm essentially arguing as one of the Bobs from Office Space. I'd like to help my friend out - but I feel like I'm getting in the middle of a political battle. More importantly - if I do get involved and suggest that his editing privileges be removed, it needs to be handled carefully so that doesn't feel belittled. He is beyond a doubt the foremost expert on this system. I'm hoping this is familiar territory for some other stackechangers, because I'm feeling a little bewildered. How should I respond? Should I argue that he shouldn't be allowed to touch the code? Should I phrase it as "no single developer, no matter how experienced, should be working on production code unchecked"? Should I argue to keep him involved with the code, but with a review process? Should I say "glad I could help, but uh, I'm busy now!" Other options? Thanks a bunch!

  • Introducing the Metro User Interface on Windows 2012

    - by andywe
    Although I am a big fan of using PowerShell to do many of my server operations, that aspect is well covered by those far more knowledgeable than I, and there is vast information around the web already on that. The new Metro interface, and getting around both Windows 8 and Windows Server 2012 though is relatively new, even for those whop ran the previews. What is this? A blank Desktop!   Where did the start button go? Well, it is still there...sort of. It is hidden, and acts like an auto hidden component that appear only when the mouse is hovered over the lower left corner of the screen. Those familiar with Gnome or OSX can relate this to the "Hot Corners" functions. To get to the start button, hover your mouse in the very left corner of the task bar. Let it sit there a moment, and a small blue square with colored tiles in it called start will appear. Click it. I clicked it and now I have all the tiles..What is this?   Welcome to the Metro interface. This is a much more modern look, and although at first seems weird and cumbersome, I have actually found that it is a bit more extensible, allowing greater organization and customization than the older explorer desktop. If you look closely, you'll see each box represents either a program, or program group. First, a few basics about using the start view. First and foremost, a right mouse click will bring up a bar on the bottom, with an icon towards the right. Notice it is titled “All Apps”. An even easier way in many places is to hover your mouse in the exact opposite corner, in the upper right. A sidebar will open and expose what used to be a widget bar (remember Vista?), and there are options for Search, Start, and Settings.   Ok Great, but where is everything? It’s all there…Click the All Apps icon.   Look better? Notice the scroll bar at the bottom. Move it right..your desktop is sized to your content..so you can have a smaller, or larger amount of programs exposed. Each icon can be secondary clicked (right mouse click for most of us, and an options bar at the bottom, rather than the old small context menu, is opened with some very familiar options.   Notice the top of the Windows Explorer window has some new features. You still have your right mouse click functions, but since the shortcuts for these items already exist..just copy them. There are many ways, but here is a long way to show you more of the interface. 1. Right mouse click a program icon, and select the Open File Location option. 2. Trusty file manager opens…but if you look closely up at top edge of the window, you’ll see a nifty enhancement. An orange colored box that is titled Shortcut Tools and another lavender box Title Application tools. Each of these adds options at the top of the file manager window to make selection easy. Of course, you can still secondary click an item in the listing window too. 3. Click shortcut tools, right click your app shortcut and copy it. Then simply paste it into the desktop outside the File Explorer window Also note some of the newer features. The large icons up top below the menu that has many common operations. The options change as you select each menu item. Well, that’s it for this installment. I hope this helps you out.

  • Upgrade to Xubuntu 13.10 - Saucy Salamander

    As a common 'fashion' it is possible to upgrade an existing installation of Ubuntu or one of its derivates every six months. Of course, you might opt-in for the adventure and directly keep your system always on the latest version (including alphas and betas), or you might like to play safe and stay on the long-term support (LTS) versions which are updated every two years only. As for me, I'd like to jump from release to release on my main desktop machine. And since 17th October Saucy Salamander or also known as Ubuntu 13.10 has been released for general use. The following paragraphs document the steps I went in order to upgrade my system to the recent version. Don't worry about the fact that I'm actually using Xubuntu. It's mainly a flavoured version of Ubuntu running Xfce 4.10 as default X Window manager. Well, I have Gnome and LXDE on the same system... just out of couriosity. Preparing the system Before you think about upgrading you have to ensure that your current system is running on the latest packages. This can be done easily via a terminal like so: $ sudo apt-get update && sudo apt-get -y dist-upgrade --fix-missing Next, we are going to initiate the upgrade itself: $ sudo update-manager As a result the graphical Software Updater should inform you that a newer version of Ubuntu is available for installation. Ubuntu's Software Updater informs you whether an upgrade is available Running the upgrade After clicking 'Upgrade...' you will be presented with information about the new version. Details about Ubuntu 13.10 (Saucy Salamander) Simply continue with the procedure and your system will be analysed for the next steps. Analysing the existing system and preparing the actual upgrade to 13.10 Next, we are at the point of no return. Last confirmation dialog before having a coffee break while your machine is occupied to download the necessary packages. Not the best bandwidth at hand after all... yours might be faster. Are you really sure that you want to start the upgrade? Let's go and have fun! Anyway, bye bye Raring Ringtail and Welcome Saucy Salamander! In case that you added any additional repositories like Medibuntu or PPAs you will be informed that they are going to be disabled during the upgrade and they might require some manual intervention after completion. Ubuntu is playing safe and third party repositories are disabled during the upgrade Well, depending on your internet bandwidth this might take something between a couple of minutes and some hours to download all the packages and then trigger the actual installation process. In my case I left my PC unattended during the night. Time to reboot Finally, it's time to restart your system and see what's going to happen... In my case absolutely nothing unexpected. The system booted the new kernel 3.11.0 as usual and I was greeted by a new login screen. Honestly, 'same' system as before - which is good and I love that fact of consistency - and I can continue to work productively. And also Software Updater confirms that we just had a painless upgrade: System is running Ubuntu 13.10 - Saucy Salamander - and up to date See you in six months again... ;-) Post-scriptum In case that you would to upgrade to the latest development version of Ubuntu, run the following command in a console: $ sudo update-manager -d And repeat all steps as described above.

  • Keymap issues with NX from Mac OS X Lion

    - by Andy
    I tried to answer the question from Mark: Keymap issues with NX from Mac OS X Lion to Ubuntu However, it is locked so I figured I would post a new question / answer. I have been trying to answer this for a few days now because I have no issues when connecting through NX Client (technically OpenNX) to FreeNX server from an iMac (with Lion), but if I try to connect with a Macbook Pro I get horrible keyboard binding issues. The fix that is working for me is to go into: ~/.nx/config/HOST.nxs and change: <option key="Current keyboard" value="false"/> <option key="Custom keyboard layout" value="empty"/> <option key="Grab keyboard" value="false"/> I have tried this on three NX Servers and all are fixed. Hope it helps or gets you closer. Always check in the ~/.nx/temp/ for the sshlog and see if --keyboard="empty/empty" instead of "pc105/en" because the Mac is really pc104. 9:05:35: startsession --session="HOST" --type="unix-gnome" --cache="8M" --images="32M" --link="adsl" --geometry="2556\ x1396" --screeninfo="2560x1440x32+render" --keyboard="empty/empty" --backingstore="1" --encryption="1" --composite="1" --\ shmem="1" --shpix="1" --streaming="1" --samba="0" --cups="0" --nodelay="1" --defer="0" --client="macosx" --media="0" --st\ rict="0" --aux="1"

  • RHEL 5.3 Kickstart - How specify location of individual package in Workstation folder?

    - by Ed
    I keep getting "package does not exist" errors during the install. I made a kickstart ISO to create an unattended install of a RHEL 5.3 build machine for C++ software releases. It pulls the kickstart config file from our internal web server. This is handy; it makes it easy to test and modify without having to make a new ISO. And I plan to check it in to version control if I can get it working. Anyway, the rpm packages are located in two folders on the disk; Client and Workstation. The packages install fine for the ones that are physically located under the Client folder. It cannot find those under the Workstation folder such as as doxygen and subversion complaining that packages do not exist. Is there a way to specify the individual package location? # ----------------------------------------------------------------------------- # P A C K A G E S # ----------------------------------------------------------------------------- %packages @gnome-desktop @core @base @base-x @printing @development-tools emacs kexec-tools fipscheck xorg-x11-server-Xnest xorg-x11-server-Xvfb #Packages Located in Workstation Folder *** Install can not find any of these ?? bison doxygen gcc-c++ subversion zlib-devel freetype-devel libxml2-devel Thanks in advance, -Ed

  • SWT: problems with clicking button after using setEnabled() on Linux

    - by Laimoncijus
    Hi, I have a strange case with SWT and Button after using setEnabled() - seems if I disable and enable button at least once - I cannot properly click with mouse on it anymore... Already minify code to very basic: import org.eclipse.swt.SWT; import org.eclipse.swt.events.SelectionEvent; import org.eclipse.swt.events.SelectionListener; import org.eclipse.swt.layout.GridLayout; import org.eclipse.swt.widgets.Button; import org.eclipse.swt.widgets.Display; import org.eclipse.swt.widgets.Shell; public class TestButton { public TestButton() { Display display = new Display(); Shell shell = new Shell(display); GridLayout mainLayout = new GridLayout(); shell.setLayout(mainLayout); shell.setSize(100, 100); Button testButton = new Button(shell, SWT.PUSH); testButton.addSelectionListener(new TestClickListener()); testButton.setText("Click me!"); //testButton.setEnabled(false); //testButton.setEnabled(true); shell.open(); while (!shell.isDisposed()) { if (!display.readAndDispatch()) display.sleep(); } display.dispose(); } class TestClickListener implements SelectionListener { @Override public void widgetDefaultSelected(SelectionEvent e) { } @Override public void widgetSelected(SelectionEvent e) { System.out.println("Click!"); } } public static void main(String[] args) { new TestButton(); } } When I keep these 2 lines commented out - I can properly click on a button and always get "Click!" logged, but if I uncomment them - then I can't click on button properly with mouse anymore - button visually seems to be clicked, but nothing is logged... Am I doing something wrong here? Or maybe it's some kind of bug on Linux platform? Because on Mac running the same code I never experienced such problems... Thanks for any hint! P.S. Running code on Ubuntu 9.10, Gnome + Compiz, Sun Java 1.6.0.16

  • Window message procedures in Linux vs Windows

    - by mizipzor
    In Windows when you create a window, you must define a (c++) LRESULT CALLBACK message_proc(HWND Handle, UINT Message, WPARAM WParam, LPARAM LParam); to handle all the messages sent from the OS to the window, like keypresses and such. Im looking to do some reading on how the same system works in Linux. Maybe it is because I fall a bit short on the terminology but I fail to find anything on this through google (although Im sure there must be plenty!). Is it still just one single C function that handles all the communication? Does the function definition differ on different WMs (Gnome, KDE) or is it handled on a lower level in the OS? Edit: Ive looked into tools like QT and WxWidgets, but those frameworks seems to be geared more towards developing GUI extensive applications. Im rather looking for a way to create a basic window (restrict resize, borders/decorations) for my OGL graphics and retrieve input on more than one platform. And according to my initial research, this kind of function is the only way to retrieve that input. What would be the best route? Reading up, learning and then use QT or WxWidgets? Or learning how the systems work and implement those few basic features I want myself?

  • Problems compiling libjingle/gtk+-2.0 for Mac OS X

    - by mindthief
    Hi All, I'm trying to compile libjingle on Mac OSX Snow Leopard. The INSTALL file said to './configure', 'make' and 'make install', as usual. But make fails for me. Initially it gave some messages indicating that I didn't have pkg-config installed (I guess OSX doesn't come with it installed?), so I downloaded pkg-config from http://pkgconfig.freedesktop.org/releases/ Now I get this message: Package gtk+-2.0 was not found in the pkg-config search path. Perhaps you should add the directory containing `gtk+-2.0.pc' to the PKG_CONFIG_PATH environment variable No package 'gtk+-2.0' found I tried to install gtk by using the script at SourceForge: http://sourceforge.net/projects/gtk-osx/ (this is the website pointed to by the gtk website) Running the script didn't really seem to do anything, here is the output: $./gtk-osx-build-setup.sh Checking out jhbuild (2.27.3) from git...

  • What problem did MS solve by creating PowerShell? [closed]

    - by Fred
    I'm asking because PowerShell confuses me. I've been trying to write some deployment scripts using PowerShell and I've been less than enthused by the result. I have a co-worker who loves PowerShell and defends it at every turn. Said co-worker claims PowerShell was never written to be a strong shell, but instead was written to: a) Allow you to peek and poke at .NET assemblies on the command-line (why is this a reason for PowerShell to exist?) b) To be hosted in .NET applications for automation, similar to DCOP in KDE and how Gnome is using CORBA. c) to be treated as ".NET script" rather than as an actual shell (related to b). I've always felt like Windows was missing a decent way to bang out automation scripts. cmd is too simplistic in many cases, and WSH is too obtuse (although the combination can be used successfully, I'm not a fan). When I first heard about PowerShell I felt like Windows was finally getting a decent shell that would be able to help with automation of many tasks, but recent experiences, and my co-worker, tell me otherwise. To be clear, I don't take issue with the fact that it's built on .NET, or that it passes objects around rather than text (despite my Unix background :]), and I'm not arguing that PowerShell is useless, but from what I can see, it doesn't solve the problem I was hoping it would solve very well. As soon as you step outside of the .NET/Powershell world, things quit being nice and cozy for you. So with all that out of the way, what problem did MS solve by creating PowerShell, or is it some political bastard child as I suspect? I've googled and haven't hit upon anything that sufficiently answered that for me, but the more citations the better.

  • Disable Windows 8 edge gestures/hot corners for multi-touch applications while running in full screen

    - by Bondye
    I have a full screen AS3 game maby with Adobe AIR that runs in Windows 7. In this game it may not be easy to exit (think about kiosk mode, only exit by pressing esc and enter a password). Now I want this game to run in Windows 8. The game is working like expected but the anoying things are these edge gestures/hot corners (left, top, right, bottom) and the shortcuts. I've read articles but none helped me. People talk about registery edits, but I dont get this working + the user needs to restart his/hers computer. I want to open my game, turn off gestures/hot corners and when the game closes the gestures/hot corners need to come back available again. I have seen some applications doing the same what I want to accomplish. I found this so I am able to detect the gestures. But how to ignore they're actions? I also read ASUS Smart Gestures but this is for the touch-pad. And I have tried Classic Shell but I need to disable the edge gestures/hot corners without such programs, just on-the-fly. I also found this but I don't know how to implement this. HRESULT SetTouchDisableProperty(HWND hwnd, BOOL fDisableTouch) { IPropertyStore* pPropStore; HRESULT hrReturnValue = SHGetPropertyStoreForWindow(hwnd, IID_PPV_ARGS(&pPropStore)); if (SUCCEEDED(hrReturnValue)) { PROPVARIANT var; var.vt = VT_BOOL; var.boolVal = fDisableTouch ? VARIANT_TRUE : VARIANT_FALSE; hrReturnValue = pPropStore->SetValue(PKEY_EdgeGesture_DisableTouchWhenFullscreen, var); pPropStore->Release(); } return hrReturnValue; } Does anyone know how I can do this? Or point me into the right direction? I have tried some in C# and C++, but I aint a skilled C#/C++ developer. Also the game is made in AS3 so it will be hard to implement this in C#/C++. I work on the Lenovo aio (All in one) with Windows 8.

  • problem with NHibernate and iSeries DB2

    - by chrisjlong
    Ok So I have an AS400/iSeries running v5r4. I have an application that was using classic NHibernate to connect and do some basic crud. Now I have pulled that app (which sat for 2 years) off the shelf of TFS and onto a new PC and cannot seem to get it running. Here is my Hibernate Config: <hibernate-configuration xmlns="urn:nhibernate-configuration-2.2"> <session-factory> <property name="connection.provider"> NHibernate.Connection.DriverConnectionProvider </property> <property name="dialect"> NHibernate.Dialect.DB2400Dialect </property> <property name="proxyfactory.factory_class">NHibernate.ByteCode.LinFu.ProxyFactoryFactory, NHibernate.ByteCode.LinFu</property> <property name="connection.connection_string"> DataSource=207.206.106.19; Database=AS400; userID=XXXXXX; Password=XXXXXXX; LibraryList=FMSFILTST,BEFFILT,HRDBFT,HRCSTFT,J20##X2DEV,GLCUSTDEV,OSL@@F3DEV; Naming=System; Initial Catalog=*SYSBAS; </property> <property name="use_outer_join">true</property> <property name="query.substitutions"> true 1, false 0, yes 'Y', no 'N' </property> <property name="show_sql">false</property> <mapping assembly="BusinessLogic" /> </session-factory> </hibernate-configuration> I have all the proper DLL's included (NHibernate, castle, iesi, antlr3 , log4 etc). Also have this line in my web.config <runtime> <assemblyBinding> <qualifyAssembly partialName="IBM.Data.DB2.iSeries" fullName="IBM.Data.DB2.iSeries,Version=10.0.0.0,PublicKeyToken=9CDB2EBFB1F93A26,Culture=neutral"/> </assemblyBinding> </runtime> Yet I am still getting the following error as soon as I call NHibernate.Cfg.Configuration().Configure().BuildSessionFactory().OpenSession(); The error is as follows Unable to cast object of type 'IBM.Data.DB2.iSeries.iDB2Connection' to type 'System.Data.Common.DbCommand' I am dying to get some help with this. Any assistance is appreciated. Thanks!

  • Best programming aids for a quadriplegic programmer

    - by Peter Rowell
    Before you jump to conclusions, yes, this is programming related. It covers a situation that comes under the heading of, "There, but for the grace of God, go you or I." This is brand new territory for me so I'm asking for some serious help here. A young man, Honza Ripa, in a nearby town did the classic Dumb Thing two weeks after graduating from High School -- he dove into shallow water in the Russian River and had a C-4/C-5 break, sometimes called a Swimming Pool break. In a matter of seconds he went from an exceptional golfer and wrestler to a quadriplegic. (Read the story ... all of us should have been so lucky as to have a girlfriend like Brianna.) That was 10 months ago and he has regained only tiny amounts of control of his right index finger and a couple of other hand/foot motions, none of them fine-grained. His total control of his computer (currently running Win7, but we can change that as needed) is via voice command. Honza's not dumb. He had a 3.7 GPA with AP math and physics. The Problems: Since all of his input is via voice command, he is concerned that the predominance of special characters in programming will require vast amount of verbose commands. Does anyone know of any well done voice input system specifically designed for programmers? I'm thinking about something that might be modal--e.g. you say "Python input" and it goes into a macro mode for doing class definitions, etc. Given all of the RSI in programmer-land there's got to be something out there. What OS(es) does it run on? I am planning on teaching him Python, which is my preferred language for programming and teaching. Are there any applications / whatevers that are written in Python and would be a particularly good match for engaging him mentally while supporting his disability? One of his expressed interests is in stock investing, but that not might be a good starting point for a brand-new programmer. There are a lot of environments (Flash, JavaScript, etc) that are not particularly friendly to people with accessibility challenges. I vaguely remember (but cannot find) a research project that basically created an overlay system on top of a screen environment and then allowed macro command construction on top of the screen image. If we can get/train this system, we may be able to remove many hurdles to using the net. I am particularly interested in finding open source Python-based robotics and robotic prostheses projects so that he can simultaneously learn advanced programming concepts while learning to solve some of his own immediate problems. I've done a ton of googling on this, but I know there things I'm missing. I'm asking the SO community to step up to the plate here. I know this group has the answers, so let me hear them! Overwhelm me with the opportunities that any of us might have/need to still program after such a life-changing event.

  • Asp.Net MVC Data Annotations. How to get client side validation on 2 properties being equal

    - by Mark
    How do you get client side validation on two properties such as the classic password confirm password scenario. I'm using a metadata class based on EF mapping to my DB table, heres the code. The commented out attributes on my class will get me server side validation but not client side. [MetadataType(typeof(MemberMD))] public partial class Member { //[CustomValidation(typeof(MemberMD), "Verify", ErrorMessage = "The password and confirmation password did not match.")] //[PropertiesMustMatch("Password", "ConfirmPassword", ErrorMessage = "The password and confirmation password did not match.")] public class MemberMD { [Required(ErrorMessage = "Name is required.")] [StringLength(50, ErrorMessage = "No more than 50 characters")] public object Name { get; set; } [Required(ErrorMessage = "Email is required.")] [StringLength(50, ErrorMessage = "No more than 50 characters.")] [RegularExpression(".+\\@.+\\..+", ErrorMessage = "Valid email required e.g. [email protected]")] public object Email { get; set; } [Required(ErrorMessage = "Password is required.")] [StringLength(30, ErrorMessage = "No more than 30 characters.")] [RegularExpression("[\\S]{6,}", ErrorMessage = "Must be at least 6 characters.")] public object Password { get; set; } [Required] public object ConfirmPassword { get; set; } [Range(0, 150), Required] public object Age { get; set; } [Required(ErrorMessage = "Postcode is required.")] [RegularExpression(@"^[a-zA-Z0-9 ]{1,10}$", ErrorMessage = "Postcode must be alphanumeric and no more than 10 characters in length")] public object Postcode { get; set; } [DisplayName("Security Question")] [Required] public object SecurityQuestion { get; set; } [DisplayName("Security Answer")] [Required] [StringLength(50, ErrorMessage = "No more than 50 characters.")] public object SecurityAnswer { get; set; } public static ValidationResult Verify(MemberMD t) { if (t.Password == t.ConfirmPassword) return ValidationResult.Success; else return new ValidationResult(""); } } Any help would be greatly appreciated, as I have only been doing this 5 months please try not to blow my mind.

  • Problems with office automation in asp.net. I can use alternatives such as open-office, if I knew ho

    - by Vinicius Melquiades
    I have a ASP.NET 2.0 web application that should upload a ppt file and then extract its slides to images. For that I have imported office.dll and Microsoft.Office.Interop.PowerPoint.dll assemblies and wrote the following code public static int ExtractImages(string ppt, string targetPath, int width, int height) { var pptApplication = new ApplicationClass(); var pptPresentation = pptApplication.Presentations.Open(ppt, MsoTriState.msoTrue, MsoTriState.msoFalse, MsoTriState.msoFalse); var slides = new List<string>(); for (var i = 1; i <= pptPresentation.Slides.Count; i++) { var target = string.Format(targetPath, i); pptPresentation.Slides[i].Export(target, "jpg", width, height); slides.Add(new FileInfo(target).Name); } pptPresentation.Close(); return slides.Count; } If I run this code in my local machine, in asp.net or a executable, it runs perfectly. But If I try running it in the production server, I get the following error: System.Runtime.InteropServices.COMException (0x80004005): PowerPoint could not open the file. at Microsoft.Office.Interop.PowerPoint.Presentations.Open(String FileName, MsoTriState ReadOnly, MsoTriState Untitled, MsoTriState WithWindow) at PPTImageExtractor.PptConversor.ExtractImages(String caminhoPpt, String caminhoDestino, Int32 largura, Int32 altura, String caminhoThumbs, Int32 larguraThumb, Int32 alturaThumb, Boolean geraXml) at Upload.ProcessRequest(HttpContext context) The process is running with the user NT AUTHORITY\NETWORK SERVICE. IIS is configured to use anonymous authentication. The anonymous user is an administrator, I set it like this to allow the application to run without having to worry about permissions. In my development machine I have office 2010 beta1. I have tested with the executable in a pc with office 2007 as well. And if I run the code from the executable in the server, with office 2003 installed, it runs perfectly. To ensure that there wouldn't be any problems with permissions, everyone in the server has full access to the web site. The website is running in IIS7 and Classic Mode. I also heard that Open-office has an API that should be able to do this, but I couldn't find anything about it. I don't mind using DLLImport to do what I have to do and I can install open-office on the web server. Don't worry about rewriting this method, as long as the parameters are the same, everything will work. I appreciate your help. ps: Sorry for bad English.

    My application works just fine until, in some unidentified conditions, it begins throwing this errors: When these errors start appearing, they appear in all over the application, no matter the code is built using ObjectDataSource or SqlDataSource.

  • Tridion Installation

    - by Kevin Brydon
    I am currently upgrading an installation of Tridion from 5.3 to 2011 starting almost from scratch (aside from migrating the database), brand new virtual servers. I just want to ask for some advice on my current server setup... a sanity check. All servers are running Windows Server 2008. The pages on our website are all classic ASP. Database SQL Server cluster. The 5.3 database has been migrated using the DatabaseManager. This is pretty standard and works well (in test anyway). Content Manager A single server to run the Content Manager and the Publisher. There are around 10 people using it at any one time so not under a particularly heavy load. Content Data Store Filesystem located somewhere on the network. One directory for live and one for staging. Content Delivery Two servers (cd1 and cd2) each with the the following server roles installed. cd1 writes to a filesystem content data store for the live website, cd2 writes to the content data store for the staging website. Presentation Two public facing web servers (web1 and web2) serving both the live and staging websites. The web servers read directly from the content data store as its a filesystem. Each of the web servers have the Content Delivery Server installed so that I can use dynamic linking (and other features?). I've so far set up everything but the web servers. Any thoughts? edit Thanks to Ram S who linked me to a decent walkthrough, upvoted. I suppose I should have posed some questions as I didn't really ask a question. I guess I'm a little confused over the content deliver aspect. I have the Content Delivery split in two separate parts. cd1 and cd2 do the work of shifting information from the Content Manager to the Staging/Live web directories. web1 and web2 should do the work of serving the web pages to the outside world and will interact with the content data store (file system). Is this a correct setup? I need some parts of the Content Delivery on my web servers right? Theoretically I could get rid of the cd1 and cd2 servers and use web1 and web2 to do the deployment right? But I suspect this will put the web servers under unnecessary strain should there ever be a big publish. I've been reading the 2011 Installation Manual, Content Delivery section, and I'm finding it quite hard to get my head around!

  • How to install 32-bit libraries using Debian Testing

    - by bgoodr
    Question: What is the way to determine, ahead of time and without doing a full install of 64-bit Debian Testing NETINST, when Debian Testing has 32-bit libraries available and fully working and installable so that the following command works without broken package errors?: apt-get install ia32-libs ia32-libs-gtk The errors that occur when 32-bit libraries are not available, still in some broken state, or whatever is broken are detailed below. I already have concluded that "Just install Stable" is my stop-gap measure for now, but I would like to know the answer to the above question so as to avoid a lengthy installation process only to run into these problems at the very end. Details: I downloaded the 64-bit Debian Testing netinst a couple of days ago. This was "Jessie" built 20131014-06:07 via http://tinyurl.com/lejpa. This is weekly testing build. Yes, I know I should expect problems, and I did. I managed to get it completely installed and was able to invoke into GNOME, but not get past the 32-bit library problem. The problems starts when I attempt to install the 32-bit libraries via: apt-get install ia32-libs ia32-libs-gtk that returns: root@breath:~# apt-get install ia32-libs ia32-libs-gtk Reading package lists... Done Building dependency tree Reading state information... Done Some packages could not be installed. This may mean that you have requested an impossible situation or if you are using the unstable distribution that some required packages have not yet been created or been moved out of Incoming. The following information may help to resolve the situation: The following packages have unmet dependencies: ia32-libs : Depends: ia32-libs-i386 but it is not installable ia32-libs-gtk : Depends: ia32-libs-i386 but it is not installable Depends: ia32-libs-gtk-i386 but it is not installable E: Unable to correct problems, you have held broken packages. I then found an old (2012 is old to me) answer at ia32-libs : Depends: ia32-libs-i386 but it is not installable and even tried what they suggested there which was dpkg --add-architecture i386 apt-get update After executing the above, I tried again but got: root@breath:~# apt-get install ia32-libs ia32-libs-gtk Reading package lists... Done Building dependency tree Reading state information... Done Some packages could not be installed. This may mean that you have requested an impossible situation or if you are using the unstable distribution that some required packages have not yet been created or been moved out of Incoming. The following information may help to resolve the situation: The following packages have unmet dependencies: ia32-libs : Depends: ia32-libs-i386 ia32-libs-gtk : Depends: ia32-libs-i386 E: Unable to correct problems, you have held broken packages. root@breath:~# And then tried this: root@breath:~# dpkg --get-selections | grep hold And that returned nothing. Not only is there broken packages, the system doesn't even know what packages are broken, so Debian Stable is my only solution I know of right now. Hence my question above.

  • How to do role-based access control for a franchise business?

    - by FreshCode
    I'm building the 2nd iteration of a web-based CRM+CMS for a franchise service business in ASP.NET MVC 2. I need to control access to each franchise's services based on the roles a user is assigned for that franchise. 4 examples: Receptionist should be able to book service jobs in for her "Atlantic Seaboard" franchise, but not do any reporting. Technician should be able to alter service jobs, but not modify invoices. Managers should be able to apply discount to invoices for jobs within their stores. Owner should be able to pull reports for any franchises he owns. Where should franchise-level access control fit in between the Data - Services - Web layer? If it belongs in my Controllers, how should I best implement it? Partial Schema Roles class int ID { get; set; } // primary key for Role string Name { get; set; } Partial Franchises class short ID { get; set; } // primary key for Franchise string Slug { get; set; } // unique key for URL access, eg /{franchise}/{job} string Name { get; set; } UserRoles mapping short FranchiseID; // related to franchises table Guid UserID; // related to Users table int RoleID; // related to Roles table DateTime ValidFrom; DateTime ValidUntil; Background I built the previous CRM in classic ASP and it runs the business well, but it's time for an upgrade to speed up workflow and leave less room for error. For the sake of proper testing and better separation between data and presentation, I decided to implement the repository pattern as seen in Rob Conery's MVC Storefront series. Controller Implementation Access Control with [Authorize] attribute If there was just one franchise involved, I could simply limit access to a controller action like so: [Authorize(Roles="Receptionist, Technician, Manager, Owner")] public ActionResult CreateJob(Job job) { ... } And since franchises don't just pop up over night, perhaps this is a strong case to use the new Areas feature in ASP.NET MVC 2? Or would this lead to duplicate Views? Controllers, URL Routing & Areas Assuming Areas aren't used, what would be the best way to determine which franchise's data is being accessed? I thought of this: {franchise}/{controller}/{action}/{id} or is it better to determine a job's franchise in a Details(...) action and limit a user's action with [Authorize]: {job}/{id}/{action}/{subaction} {invoice}/{id}/{action}/{subaction} which makes more sense if any user could potentially have access to more than one franchise without cluttering the URL with a {franchise} parameter. Any input is appreciated.

  • GOTO still considered harmful?

    - by Kyle Cronin
    Everyone is aware of Dijkstra's Letters to the editor: go to statement considered harmful (also here .html transcript and here .pdf) and there has been a formidable push since that time to eschew the goto statement whenever possible. While it's possible to use goto to produce unmaintainable, sprawling code, it nevertheless remains in modern programming languages. Even the advanced continuation control structure in Scheme can be described as a sophisticated goto. What circumstances warrant the use of goto? When is it best to avoid? As a followup question: C provides a pair of functions, setjmp and longjmp, that provide the ability to goto not just within the current stack frame but within any of the calling frames. Should these be considered as dangerous as goto? More dangerous? Dijkstra himself regretted that title, of which he was not responsible for. At the end of EWD1308 (also here .pdf) he wrote: Finally a short story for the record. In 1968, the Communications of the ACM published a text of mine under the title "The goto statement considered harmful", which in later years would be most frequently referenced, regrettably, however, often by authors who had seen no more of it than its title, which became a cornerstone of my fame by becoming a template: we would see all sorts of articles under the title "X considered harmful" for almost any X, including one titled "Dijkstra considered harmful". But what had happened? I had submitted a paper under the title "A case against the goto statement", which, in order to speed up its publication, the editor had changed into a "letter to the Editor", and in the process he had given it a new title of his own invention! The editor was Niklaus Wirth. A well thought out classic paper about this topic, to be matched to that of Dijkstra, is Structured Programming with go to Statements (also here .pdf), by Donald E. Knuth. Reading both helps to reestablish context and a non-dogmatic understanding of the subject. In this paper, Dijkstra's opinion on this case is reported and is even more strong: Donald E. Knuth: I believe that by presenting such a view I am not in fact disagreeing sharply with Dijkstra's ideas, since he recently wrote the following: "Please don't fall into the trap of believing that I am terribly dogmatical about [the go to statement]. I have the uncomfortable feeling that others are making a religion out of it, as if the conceptual problems of programming could be solved by a single trick, by a simple form of coding discipline!"
