  • MVC Scaffold Template Not Generating?

    - by monkey9987
    Been working on an MVC project and my templates were not generating. I first created my Model inside my "Models" folder, then did a quick compile. Next I went to the Views folder to get it created, right click and say "Add View" then I clicked the checkbox to create an edit page. What happened was the template would never seem to pull in my Model, it would just have the default header items, but the entire model was missing.  My model was defined as follows: public class LogOnModel { [Required][Display(Name = "User name")]public string UserName;[Required][DataType(DataType.Password)][Display(Name = "Password")]public string Password;[Display(Name = "Remember me?")]public bool RememberMe; } See anything wrong with that? I couldn't figure out why each time I created my View and selected the option to create the "Edit" scaffold automatically, it would come up blank. Turns out I'm missing my get / set methods on the Model class items. Here's my code with the correct setup: public class LogOnModel { [Required][Display(Name = "User name")]public string UserName { get; set; } [Required][DataType(DataType.Password)][Display(Name = "Password")]public string Password { get; set; }[Display(Name = "Remember me?")]public bool RememberMe { get; set; } }  I hope that helps someone out, it's pretty simple when I look at it now, but that's always the case!  ~ Steve

  • Adding tolerance to a point in polygon test

    - by David Gouveia
    I've been using this method which was taken from Game Coding Complete to detect whether a point is inside of a polygon. It works in almost every case, but is failing on a few edge cases, and I can't figure out the reason. For example, given a polygon with vertices at (0,0) (0,100) and (100,100), the algorithm is returning: True for any point strictly inside the polygon False for any of the vertices False for (0, 50) which lies on one of the edges of the polygon True (?) for (50,50) which is also on one of the edges of the polygon I'd actually like to relax the algorithm so that it returns true in all of these cases. In other words, it should return true for points that are strictly inside, for the vertices themselves, and for points on the edges of the polygon. If possible I'd also like to give it enough tolerance so that it always tend towards "true" in face of floating point fluctuations. For example, I have another method, that given a line segment and a point, returns the closest location on the line segment to the given point. Currently, given any point outside the polygon and one of its edges, there are cases where the result is categorized as being inside by the method above, while other points are considered outside. I'd like to give it enough tolerance so that it always returns true in this situation. The way I've currently solved the problem is an hack, which consists of using an external library to inflate the polygon by a few pixels, and performing the tests on the inflated polygon, but I'd really like to replace this with a proper solution.

  • Reaching Intermediate Programming Status

    - by George Stocker
    I am a software engineer that's had positions programming in VBA (though I dare not consider that 'real' experience, as it was trial and error!), Perl w/ CGI, C#, and ASP.NET. The latter two are post-undergraduate, with my entrance into the 'real world'. I'm 2 years out of college, and have had 5 years of experience (total) across the languages I've mentioned. However, when it comes to my resume, I can only put 2 years down for C#, and less than a year down for ASP.NET. I feel like I know C#, but I still have to spend time going 'What does this method do?', whereas some of the more senior level engineers can immediately say, "Oh, Method X does this, without ever having looked at that method before." So I know empirically that there's a gulf there, but I'm not exactly sure how to bridge it. I've started programming in Project Euler, and I picked up a book on design patterns, but I still feel like I spend each day treading water, instead of moving forward. That isn't to say that I don't feel like I've made progress, it just means that as far as I come each day, I still see the mountain top way off in the distance. My question is this: How did you overcome this plateau? How long did it take you? What methods can you suggest to assist me in this? I've read through Code Complete, The Mythical Man Month, and CLR via C#, 2nd edition -- my question is: What do I do now? Edit: I just found this question on projects for an intermediate level programmer. I think it adds to the discussion (though it does not supplant my question). As such, I'm adding it to the question as a "For More Information".

  • Can't mount USB devices, shut down etc. as a user

    - by Alok
    I tried gnome3 and gnome3-staging ppas to test running Gnome 3.8. After a while I decided that Gnome 3.8 wasn't for me, so I did a ppa-purge of both the ppas. As described in gnome3-staging ppa page, I also did: $ sudo apt-get purge libpam-systemd $ sudo apt-get install libpam-xdg-support The trouble is, I can't mount my external USB device anymore. When I try to mount it as a user, it fails: $ udisks --mount /dev/sdc1 Mount failed: Not Authorized I am logged in an XFCE session, but the same thing happens in a fallback Gnome session, or from a Unity session. Also, in XFCE, "suspend" and "shut down" menus are grayed out. I can't also open synaptic package manager from XFCE menus (sudo synaptic works). After a lot of searching, it seems like it is a policykit issue. I see the following in my ~/.xsession-errors: (polkit-gnome-authentication-agent-1:5805): polkit-gnome-1-WARNING **: Unable to determine the session we are in: No session for pid 5805 PID 5805 doesn't exist. If I try to start polkit-dnome-authentication-agent-1 from an xterm, I get the same error (different PID): $ /usr/lib/policykit-1-gnome/polkit-gnome-authentication-agent-1 ... (polkit-gnome-authentication-agent-1:15971): polkit-gnome-1-WARNING **: Unable to determine the session we are in: No session for pid 15971 (the ... lines are warnings from GTK about missing css files etc.). polkitd is running: $ pidof polkitd 1495 Is there something I am missing?

  • Is it necessary to add an HP printer to CUPS using the hplip URI?

    - by JPbuntu
    I recently setup a CUPS print server (Ubuntu server 12.04) and I having trouble with performance of a HP Color LaserJet Printer CP3505n. The printer pauses for about a second between printing each page, which is annoying when there is a lot of printing to be done. This doesn't happen when the printer is installed directly to a Windows client. In an attempt to fix this I have setup the printer a couple different ways. I decided not to do a Samba share since this wiki said IPP is preferred. First Method Added to HP LaserJet to CUPS as a Discovered Network Printer, and selected HP Color LaserJet cp3505 hpijs pcl3, 3.12.2 (en) driver. I did not use a hplip URI. Second Method (hplip URI) I thought adding hplip to the mix might improve the performance, so I added the printer like this: Ran hp-setup -m 192.168.2.60, prompted to select driver Selected HP Color LaserJet cp3505 hpijs pcl3, 3.12.2 (en) Used hplip to generate a URI: hp-makeuri 192.168.2.60 Then added the printer to CUPS as a Local Printer: HP Printer (HPLIP), and entered: hp:/net/HP_Color_LaserJet_CP3505?ip=192.168.2.60. Either method I use I am able to share the printer on the network by adding a printer as http://192.168.2.2:631/printers/HP_LASER-TERRAC. Does it make a difference which way the printer is added cups? If so, and I install the printer with the hp URI, can I still change the driver using the CUPS web interface? I have been trying out different drivers to try and improve performance, and the cups interface is the easiest way to change them. Thanks in advance.

  • 12.04 update crash, now cannot boot

    - by EdW
    Boot now freezes the system at the "Ubuntu purple screen" with the 5 dots under it. I cannot even CTRL-ALT-F1 to get to an alternate console. Have to push reset button on computer to reboot. After the 12.04 update crash, the system would boot, but I had no icons and no launch bar and errors about missing dependencies. CTRL-ALT-F1 and ran apt-get -f install and it appeared to get the missing packages. I followed with a apt-get update; apt-get upgrade. It appeared to install all of the remaining 12.04 update packages. Rebooted to same blank screen - no icons, but got a compiz error. In console I tried "unity --reset" rebooted ... Nothing ... It's dead in the water. Tried to boot into Recovery Mode - black screen - I cannot even CTRL-ALT-Del - have to push reboot button. Fortunately, I have Mint on another partition and I can access the broken 12.04 partition. Ideas? I can back up all of my folders using Mint, but I would hate to have to do a new install.

  • How to write PowerShell code part 2 (Using function)

    - by ybbest
    In the last post, I have showed you how to use external configuration file in your PowerShell script. In this post, I will show you how to create PowerShell function and call external PowerShell script.You can download the script here. 1. In the original script, I create the site directly using New-SPSite command. I will refactor it so that I will create a new function to create the site using New-SPSite. The PowerShell function is quite similar to a C# method. You put your function parameters in () and separate each parameter by a comma (,). Then you put your method body in {}. function add ([int] $num1 , [int] $num2){ $total=$num1+$num2 #Return $total $total } 2. The difference is you do not need semi-colon (;) at the end of each statement and when calling the method you do not need comma (,) to separate each parameter. function add ([int] $num1 , [int] $num2){ $total=$num1+$num2 #Return $total $total } #Calling the function [int] $num1=3 [int] $num2=4 $d= add $num1 $num2 Write-Host $d 3. If you like to return anything from the function, you just need to type in the object you like to return, not need to type return .e.g. $ObjectToReturn not return $ObjectToReturn

  • Ninject/DI: How to correctly pass initialisation data to injected type at runtime

    - by MrLane
    I have the following two classes: public class StoreService : IStoreService { private IEmailService _emailService; public StoreService(IEmailService emailService) { _emailService = emailService; } } public class EmailService : IEmailService { } Using Ninject I can set up bindings no problem to get it to inject a concrete implementation of IEmailService into the StoreService constructor. StoreService is actually injected into the code behind of an ASP.NET WebForm as so: [Ninject.Inject] public IStoreService StoreService { get; set; } But now I need to change EmailService to accept an object that contains SMTP related settings (that are pulled from the ApplicationSettings of the Web.config). So I changed EmailService to now look like this: public class EmailService : IEmailService { private SMTPSettings _smtpSettings; public void SetSMTPSettings(SMTPSettings smtpSettings) { _smtpSettings = smtpSettings; } } Setting SMTPSettings in this way also requires it to be passed into StoreService (via another public method). This has to be done in the Page_Load method in the WebForms code behind (I only have access to the Settings class in the UI layer). With manual/poor mans DI I could pass SMTPSettings directly into the constructor of EmailService and then inject EmailService into the StoreService constructor. With Ninject I don't have access to the instances of injected types outside of the objects they are injected to, so I have to set their data AFTER Ninject has already injected them via a separate public setter method. This to me seems wrong. How should I really be solving this scenario?

  • Freescale One Box Unboxing (then installing Java SE Embedded technology)

    - by hinkmond
    So, I get a FedEx delivery the other day... "What cool device could be inside this FedEx Overnight Express Large Box?" I was wondering... Could it be a new Linux/ARM target device board, faster than a Raspberry Pi and better than a BeagleBone Black??? Why, yes! Yes, it was a Linux/ARM target device board, faster than anything around! It was a Freescale i.MX6 Sabre Smart Device Board (SDB)! Cool... Quad Core ARM Cortex A9 1GHz with 1GB of RAM. So, cool... I installed the Freescale One Box OpenWRT Linux image onto its SD card and booted it up into Linux. But, wait! One thing was missing... What was it? What could be missing? Why, it had no Java SE Embedded installed on it yet, of course! So, I went to the JDK 7u45 download link. Clicked on "Accept License Agreement", and clicked on "jdk-7u45-linux-arm-vfp-sflt.tar.gz", installed the bad boy, and all was good. Java SE Embedded 7u45 on a Freescale One Box. Nice... Hinkmond

  • How to implment the database for event conditions and item bonuses for a browser based game

    - by Saifis
    I am currently creating a browser based game, and was wondering what was the standard approach in making diverse conditions and status bonuses database wise. Currently considering two cases. Event Conditions Needs min 1000 gold Needs min Lv 10 Needs certain item. Needs fulfillment of another event Status Bonus Reduces damage by 20% +100 attack points Deflects certain type of attack I wish to be able to continually change these parameters during the process of production and operation, so having them hard-coded isn't the best way. All I could come up with are the following two methods. Method 1 Create a table that contains each conditions with needed attributes Have a model named conditions with all the attributes it would need to set them conditions condition_type (level, money_min, money_max item, event_aquired) condition_amount prerequisite_condition_id prerequisite_item_id Method 2 write it in a DSL form that could be interpreted later in the code Perhaps something like yaml, have a text area in the setting form and have the code interpret it. condition_foo: condition_type :level min_level: 10 condition_type :item item_id: 2 At current Method 2 looks to be more practical and flexible for future changes, trade off being that all the flex must be done on the code side. Not to sure how this is supposed to be done, is it supposed to be hard coded? separate config file? Any help would be appreciated. Added For additional info, it will be implemented with Ruby on Rails

  • Kinect Click counter function

    - by Sweta Dwivedi
    So i have the following kinect click function which will check if the hand is within the bounds then it will click with a counter . . however there is a slight problem . .the first few button clicks work fine.. but after it clicks one of the buttons it changes the game state and immediately clicks the other button without the counter reaching 200. . . Kinect click is a method in the button class. . .and each button inside a list can access the Kinect click method. . . public bool KinectClick(int x,int y) { if ((x >= position.X && x <= position.X + position.Width) && (y >= position.Y && y <= position.Y + position.Height)) { counter++; if (counter > 200) { counter = 0; return true; } } else { counter = 0; } return false; } I call to check if this property is true in the Game update method to act as a button click. . foreach(Button g_t in Game_theme) { if ((g_t.KinectClick(x_c, y_c) == true || g_t.ButtonClicked() == true) && g_t.name == "animoe") { Selected_anim = true; currentGameState = GameState.InGame; } if ((g_t.KinectClick(x_c, y_c) == true || g_t.ButtonClicked() == true) && g_t.name == "planet") { Selected_planet = true; currentGameState = GameState.InGame; }

  • ubuntu 12.04 desktop Error: unknown command 'gfxmode'. Pressing any key continues

    - by Andy
    Premise: linux noobie here, I have the same issue as OP: fresh 12.04 desktop, changed grub with grub customizer, now I get a: unknown command 'gfxmode' press ...etc was asked to "re-post" this question and link to this thread which I refer to above. I have tried what Tarek said, and nothing seems to work, I find two lines with gfxmode: function gfxmode { gfxmode \$linux_gfx_mode Note: not sure if it matter but in the error the two single quotes before gfxmode are not the same, the first is a slanted quote mark, the second (after gfxmode) is a straight one. I commented out the whole line, I tried to add 'set' before gfxmode, neither did any difference. I found another place that said to remove the line from another file 40_custom, but I checked and those files do not contain anything relating to the line we are looking for: gfxmode $linux_gfx_mode Not sure what I am missing, but the file linux.save has recently appeared when searching for the line. Not sure if its just a temp file of some kind. In any case I cannot seem to get it, what am I missing? Thanks! P.S. sorry for any messups in form :)

  • Basic 3D Collision detection in XNA 4.0

    - by NDraskovic
    I have a problem with detecting collision between 2 models using BoundingSpheres in XNA 4.0. The code I'm using i very simple: private bool IsCollision(Model model1, Matrix world1, Model model2, Matrix world2) { for (int meshIndex1 = 0; meshIndex1 < model1.Meshes.Count; meshIndex1++) { BoundingSphere sphere1 = model1.Meshes[meshIndex1].BoundingSphere; sphere1 = sphere1.Transform(world1); for (int meshIndex2 = 0; meshIndex2 < model2.Meshes.Count; meshIndex2++) { BoundingSphere sphere2 = model2.Meshes[meshIndex2].BoundingSphere; sphere2 = sphere2.Transform(world2); if (sphere1.Intersects(sphere2)) return true; } } return false; } The problem I'm getting is that when I call this method from the Update method, the program behaves as if this method always returns true value (which of course is not correct). The code for calling is very simple (although this is only the test code): if (IsCollision(model1, worldModel1, model2, worldModel2)) { Window.Title = "Intersects"; } What is causing this?

  • How to make my simple round sprite look right in XNA

    - by Joshua Perina
    Ok, I'm very new to graphics programming (but not new to coding). I'm trying to load a simple image in XNA which I can do fine. It is a simple round circle which I made in photoshop. The problem is the edges show up rough when I draw it on the screen even with the exact size. The anti-aliasing is missing. I'm sure I'm missing something very simple: GraphicsDevice.Clear(Color.Black); // TODO: Add your drawing code here spriteBatch.Begin(); spriteBatch.Draw(circle, new Rectangle(10, 10, 10, 10), Color.White); spriteBatch.End(); Couldn't post picture because I'm a first time poster. But my smooth png circle has rough edges. So I found that if I added: spriteBatch.Begin(SpriteSortMode.FrontToBack, BlendState.NonPremultiplied); I can get a smooth image when the image is the same size as the original png. But if I want to scale that image up or down then the rough edges return. How do I get XNA to smoothly resize my simple round image to a smaller size without getting the rough edges?

  • Versioning APIs

    - by Sharon
    Suppose that you have a large project supported by an API base. The project also ships a public API that end(ish) users can use. Sometimes you need to make changes to the API base that supports your project. For example, you need to add a feature that needs an API change, a new method, or requires altering of one of the objects, or the format of one of those objects, passed to or from the API. Assuming that you are also using these objects in your public API, the public objects will also change any time you do this, which is undesirable as your clients may rely on the API objects remaining identical for their parsing code to work. (cough C++ WSDL clients...) So one potential solution is to version the API. But when we say "version" the API, it sounds like this also must mean to version the API objects as well as well as providing duplicate method calls for each changed method signature. So I would then have a plain old clr object for each version of my api, which again seems undesirable. And even if I do this, I surely won't be building each object from scratch as that would end up with vast amounts of duplicated code. Rather, the API is likely to extend the private objects we are using for our base API, but then we run into the same problem because added properties would also be available in the public API when they are not supposed to be. So what is some sanity that is usually applied to this situation? I know many public services such as Git for Windows maintains a versioned API, but I'm having trouble imagining an architecture that supports this without vast amounts of duplicate code covering the various versioned methods and input/output objects. I'm aware that processes such as semantic versioning attempt to put some sanity on when public API breaks should occur. The problem is more that it seems like many or most changes require breaking the public API if the objects aren't more separated, but I don't see a good way to do that without duplicating code.

  • My Windows Phone 7 experience: 45 days in

    - by Enrique Lima
    November 13th, 2010 was the day I got my Windows Phone 7.  It was an exciting day, a lot of anxiety too.  Over a phone? Sadly, yes! Being a Zune Pass subscriber, it was something worth looking forward too, being a consultant that relies and works with Microsoft technologies and having the option of OneNote (without converters and such) on my phone was a great thing too. Has that changed over 45 days?  No, not really.  But I find myself at the very same place I was with my iPhone, I don’t really use the music player as I spend enough time in front of a computer where I have Pandora and the Zune Desktop.  Or in a car with Satellite Radio.  As for OneNote, that keeps me hooked and with access to my notes no matter where I take them. The Device: Samsung Focus Likes: OneNote integration, Zune capabilities (just note my comment above), fast and smooth interface, calendar, tiles, the device itself. Dislikes: Heavy glitches in SharePoint interaction. And a very weird one I have experienced is, any pictures I get sent from an iPhone via email will register as an attachment but the pictures are not listed as the attachment once I open the message … weird!!  Then, of course, some apps have not made it to the platform (not sure they ever will … Pandora??!!??  Chase??!!??).  But those apps missing is not the phone, or Microsoft’s fault (IMO).  In summary, I am happy with it, and some of the missing apps have made me shift the way I work with the products or features affected … meaning I rely on my desktop stuff for that.

  • Avoid overwriting all the methods in the child class

    - by Heckel
    The context I am making a game in C++ using SFML. I have a class that controls what is displayed on the screen (manager on the image below). It has a list of all the things to draw like images, text, etc. To be able to store them in one list I created a Drawable class from which all the other drawable class inherit. The image below represents how I would organize each class. Drawable has a virtual method Draw that will be called by the manager. Image and Text overwrite this method. My problem is that I would like Image::draw method to work for Circle, Polygon, etc. since sf::CircleShape and sf::ConvexShape inherit from sf::Shape. I thought of two ways to do that. My first idea would be for Image to have a pointer on sf::Shape, and the subclasses would make it point onto their sf::CircleShape or sf::ConvexShape classes (Like on the image below). In the Polygon constructor I would write something like ptr_shape = &polygon_shape; This doesn't look very elegant because I have two variables that are, in fact, just one. My second idea is to store the sf::CircleShape and sf::ConvexShape inside the ptr_shape like ptr_shape = new sf::ConvexShape(...); and to use a function that is only in ConvexShape I would cast it like so ((sf::ConvexShape*)ptr_shape)->convex_method(); But that doesn't look very elegant either. I am not even sure I am allowed to do that. My question I added details about the whole thing because I thought that maybe my whole architecture was wrong. I would like to know how I could design my program to be safe without overwriting all the Image methods. I apologize if this question has already been asked; I have no idea what to google.

  • What is the value to checking in broken unit tests?

    - by Adam W.
    While there are ways of keeping unit tests from being executed, what is the value of checking in broken unit tests? I will use a simple example. Case sensitivity. The current code is Case Sensitive. A valid input into the method is "Cat" and it would return an enum of Animal.Cat. However, the desired functionality of the method should not be case sensitive. So if the method described was passed "cat" it could possibly return something like Animal.Null instead of Animal.Cat and the unit test would fail. Though a simple code change would make this work, a more complex issue may take weeks to fix, but identifying the bug with a unit test could be a less complex task. The application currently being analyzed has 4 years of code that "works". However, recent discussions regarding unit tests has found flaws in the code. Some just need explicit implementation documentation (ex. case sensitive or not), or code that does not execute the bug based on how it is currently called. But unit tests can be created executing specific scenarios that will cause the bug to be seen and are valid inputs. What is the value of checking in unit tests that exercise the bug until someone can get around to fixing the code? Should this unit test be flagged with ignore, priority, category etc, to determine whether a build was successful based on tests executed? Eventually the unit test should be created to execute the code once someone fixes it. On one hand it shows that identified bugs have not been fixed. On the other, there could be hundreds of failed unit tests showing up in the logs and weeding through the ones that should fail vs. failures due to a code check-in would be difficult to find.

  • Oh snap! My RPi was upgraded to 512MB! Woo-hoo!

    - by hinkmond
    I ordered a Raspberry Pi Model B (256MB) over 4 months ago on backorder. When it finally came I saw it was upgraded to the new half a gig model! Woot! But, all was not perfect. Gary C. told me the shipped configuration of the new RPi models didn't have the right firmware for 512MB, and I had to upgrade the start.elf in the /boot directory to recognize all of the 512MB RAM. I did a "free" command, and sure enough saw only 240MB. Sadness. But, Gary gave me a copy of his start.elf which worked after some trail and error. For anyone ordering the new RPi Model B w/512MB, here are the steps to get you going with full 512MB RAM: sudo apt-get update --fix-missing sudo apt-get upgrade --fix-missing # NOTE: This step takes at least a couple hours on a # fast network wget https://raw.github.com/raspberrypi/firmware/\ 164b0fe2b3b56081c7510df93bc1440aebe45f7e/boot/\ arm496_start.elf sudo mv /boot/start.elf /boot/orig-start.elf sudo mv arm496_start.elf /boot/start.elf sudo reboot free total used free shared buffers cached Mem: 497768 210596 287172 0 16892 169624 -/+ buffers/cache: 24080 473688 Swap: 102396 0 102396 So of course this means... (drumroll) there is now 498MB available for the Java Embedded heap! java -Xmx400m -version java version "1.7.0_06" Java(TM) SE Embedded Runtime Environment (build 1.7.0_06-b24, headless) Java HotSpot(TM) Embedded Client VM (build 23.2-b09, mixed mode) Yeah, baby!

  • backlight doesn't work on acer 5732z tried everything I can find

    - by Dude Random21
    Ok if you can solve my problem you're really really good. I want to run ubuntu 12.04 on my acer aspire 5732z I know (from research) that these computer's have issues with the backlight on ubuntu. So I tried a couple of solutions: The "sudo lightdm restart" method. I get no change at all. The "sudo setpci -s 00:02.0 F4.B=30" method. This so far has been the most effective, I first tried it in the F1 console right away I get the screen back, problem is going back to the desktop it goes back to being black. So I tried it from a terminal window and it works as well but as soon as I unplug my external monitor the screen turns black again and doesn't come back. If I plug the monitor back in the screen stays black and the only thing I see is the mouse pointer. From here I go back into console (which I am able to see) and reboot from there. The "sudo sed -i 's/GRUB_CMDLINE_LINUX=""/GRUB_CMDLINE_LINUX="acpi_osi=Linux"/g' /etc/default/grub" method. This one I got no instant change and after reboot still no change. I'm open to pretty much any suggestions you may have.

  • Finding Buried Controls

    - by Bunch
    This post is pretty specific to an issue I had but still has some ideas that could be applied in other scenarios. The problem I had was updating a few buttons so their Text values could be set in the code behind which had a method to grab the proper value from an external source. This was so that if the application needed to be installed by a customer using a language other than English or needed a different notation for the button's Text they could simply update the database. Most of the time this was no big deal. However I had one instance where the button was part of a control, the button had no set ID and that control was only found in a dll. So there was no markup to edit for the Button. Also updating the dll was not an option so I had to make the best of what I had to work with. In the cs file for the aspx file with the control on it I added the Page_LoadComplete. The problem button was within a GridView so I added a foreach to go through each GridViewRow and find the button I needed. Since I did not have an ID to work with besides a random ctl00$main$DllControl$gvStuff$ctl03$ctl05 using the GridView's FindControl was out. I ended up looping through each GridViewRow, then if a RowState equaled Edit loop through the Cells, each control in the Cell and check each control to see if it held a Panel that contained the button. If the control was a Panel I could then loop through the controls in the Panel, find the Button that had text of "Update" (that was the hard coded part) and change it using the method to return the proper value from the database. if (rowState.Contains("Edit")){  foreach (DataControlFieldCell rowCell in gvr.Cells)  {   foreach (Control ctrl in rowCell.Controls)   {    if (ctrl.GetType() == typeof(Panel))     {     foreach (Control childCtrl in ctrl.Controls)     {      if (childCtrl.GetType() == typeof(Button))      {       Button update = (Button)childCtrl;       if (update.Text == "Update")       {        update.Text = method to return the external value for the button's text;       }      }     }    }   }  }} Tags: ASP.Net, CSharp

  • What level of detail to use in an interface members descriptions?

    - by famousgarkin
    I am extracting interfaces from some classes in .NET, and I am not completely sure about what level of detail of description to use for some of the interface members (properties, methods). An example: interface ISomeInterface { /// <summary> /// Checks if the object is checked out. /// </summary> /// <returns> /// Returns true if the object is checked out, or if the object locking is not enabled, /// otherwise returns false. /// </returns> bool IsObjectCheckedOut(); } class SomeImplementation : ISomeInterface { public bool IsObjectCheckedOut() { // An implementation of the method that returns true if the object is checked out, // or if the object locking is not enabled } } The part in question is the <returns>...</returns> section of the IsObjectCheckedOut description in the interface. Is it ok to include such a detail about return value in the interface itself, as the code that will work with the interface should know exactly what that method will do? All the current implementations of the method will do just that. But is it ok to limit the possible other/future implementations by description this way? Or should this not be included in the interface description, as there is no way to actually ensure that other/future implementations will do exactly this? Is it better to be as general as possible regarding the interface in such circumstances? I am currently inclined to the latter option.

  • Advice on designing web application with a 40+ year lifetime

    - by user2708395
    Scenario Currently, I am apart of a health care project whose main requirement is to capture data with unknown attributes using user generated forms by health care providers. The second requirement is that data integrity is key and that the application will be used for 40+ years. We are currently migrating the client's data from the past 40 years from various sources (Paper, Excel, Access, etc...) to the database. Future requirements are: Workflow management of forms Schedule management of forms Security/Role based management Reporting engine Mobile/Tablet support Situation Only 6 months in, the current (contracted) architect/senior programmer has taken the "fast" approach and has designed a poor system. The database is not normalized, the code is coupled, the tiers have no dedicated purpose and data is starting to go missing since he has designed some beans to perform "deletes" on the database. The code base is extremely bloated and there are jobs just to synchronize data since the database is not normalized. His approach has been to rely on backup jobs to restore missing data and doesn't seem to believe in re-factoring. Having presented my findings to the PM, the architect will be removed when his contract ends. I have been given the task to re-architect this application. My team consists of me and one junior programmer. We have no other resources. We have been granted a 6-month requirement freeze in which we can focus on re-building this system. I suggested using a CMS system like Drupal, but for policy reasons at the client's organization, the system must be built from scratch. This is the first time that I will be designing a system with a 40+ lifespan. I have only worked on projects with 3-5 year lifespans, so this situation is very new, yet exciting. Questions What design considerations will make the system more "future proof"? What experiences have you had in designing such systems - both failures and successes? What questions should be asked to the client/PM to make the system more "future proof"?
