• Should I learn VB.NET or C#?

  - by Ravi

  Background I have decided to do my graduation project (yet to start) in .NET. Regarding it, I am bit confused about: what language should I learn: VB.NET or C#? What I have learnt from those who know it that both VB.NET and C# have: The same concepts VB.NET is simpler as it is more like English statements but also C# is simple too if you already know C (Which I do know) Question So considering some factors, e.g. career point of view, newness, challenging and beneficial, etc., what language should I choose? Please help me out. And clearly do justify your answer (whatever reason you have.) References (Extra) A little information about what project I am doing: It is a database file system. Technologies I'll be using are SQL Server, WPF, etc. I just love the concept of Database file system.So those who want to know more about Database file system, here are the links DBFS (This one is really good.Serves as primary reference for me) Towards A Single Folder Filesystem stackoverflow-What is a database file system? UPDATE1 : After some really good explained answers (actually all are good at their place), I have finally decided to go with C# for myself. Thank you all. Still, you are requested to put your opinion (Once it is reopened,of course) UPDATE2 : Question reopened and made community wiki.Thank you all.

• Deployments and TFS, general questions

  - by Velika

  SOX requires that we have a separate group deploy our ASP.NET web to production. Currently, that group has access to our current code repository in VSS and uses VSS to deploy code that has been checked into VSS. How are deployments typically done for web applications? As a developer, I have used the Deploy function in Visual Studio to deploy code to a network share which corresponds to a IS virtual folder, but I don't think we can expect that the deployment group will be purchasing a copy of Visual Studio just to do deployments. We could check the code into TFS, but what is the minimum software that that group would need to perform the deployment? Would a Team Explorer Client Access suffice? I am aware that Team System has functionality to automate the building of an application. Do people typically deploy to Production by copying aspx and dlls files from the QA environment to production or do you normally deploy from TFS or even VS directly? It seems to me that the preferred approach would be to deploy from the QA environment, since that is the environment that must have been approved for release or that those files should be checked into TFS and the deployed from TFS, assuming you can deploy from TFS. What confuses me is whether bin (binary) files that are local to the project-do they go into TFS? Is so, doesn't this create problems for other developers in that only 1 developers-the one with the binary checked - can actually debug because debugging requires write access to the binaries? Does this mean that the binaries shouldn't be checked into TFS? But eventually, if you deploy from TFS, the binaries HAVE to be added to TFS. Are they added as a separate (compiled) application node? If so,m this sounds real ugly. I would assume not. How does one ensure that the binaries match the source code that we mark with a particular version number? Obviously, I'm clueless. Can someone give me a general idea of how you handle version control and deployments in particular using TFS?

• possible xml elements in Android resources xmls ?

  - by Vijay C

  I recently came across a forum post in thelink text android developers group. (link below) It has one post which contains following xml. It is xml file which can be used in drawable folder. <selector xmlns:android="http://schemas.android.com/apk/res/android"> <!-- Non focused states --> <item android:state_focused="false" android:state_selected="false" android:state_pressed="false" android:drawable="@drawable/tab_unselected" /> <item android:state_focused="false" android:state_selected="true" android:state_pressed="false" android:drawable="@drawable/tab_selected" /> <!-- Focused states --> <item android:state_focused="true" android:state_selected="false" android:state_pressed="false" android:drawable="@drawable/tab_focus" /> <item android:state_focused="true" android:state_selected="true" android:state_pressed="false" android:drawable="@drawable/tab_focus"/> <!-- Pressed --> <item android:state_pressed="true" android:drawable="@drawable/tab_press" /> </selector> Now my question is, where is the documentation which tells me that i can use the following xml tags <selector> , <item>, <color>, <integer-array>, <string-array> and many others tag to create xml resources...? I hope, i have explained what i want to know ?

• MVC keeping the PartialView in its own context - ignore the main view holding the partial view

  - by Mike

  I'm looking at the partialview components of the MVC Framework. i want my partial view to be handled in its own action and for the rest of the view to handle itself, but i'm getting an exception because the main page is not getting its view fired. Am i going around this the wrong way? My Main View (Jobs/Index.aspx): <%@ Page Title="" Language="C#" MasterPageFile="~/Views/Shared/Site.Master" Inherits="System.Web.Mvc.ViewPage<MvcApplication3.Models.JobViewModel>" %> <asp:Content ID="Content2" ContentPlaceHolderID="MainContent" runat="server"> <% Html.RenderPartial("JobListing", Model.Jobs); %> </asp:Content> The partialview (Jobs/JobListing.ascx): <%@ Control Language="C#" Inherits="System.Web.Mvc.ViewUserControl<List<MvcApplication3.Models.Job>>" %> <table> <tr> <td> Job Title </td> <td> Job Location</td> </tr> <% foreach (var job in Model) { %> <tr> <td> <%= job.Title %> </td> <td> <%= job.Location %> </td> </tr> <% } %> <% Html.BeginForm("DoSomeStuff", "Job", null, FormMethod.Post); %> <%= Html.TextBox("SomeInfo") %> <button type="submit" id="submit" /> <% Html.EndForm(); %> The main controller for both the main view (Index) and the partialview (DoSomeStuff()) public class JobController : Controller { public ActionResult Index() { JobProvider provider = new JobProvider(Session); JobViewModel vm = new JobViewModel(); vm.Jobs = provider.GetJobs(); return View(vm); } public PartialViewResult DoSomeStuff() { return PartialView("JobListing"); } } As you can see in the partial view, it has its own form that posts to the Action called DoSomeStuff(). i want this action to handle any data submitted from that form. but when the form is submitted the main action (Index) does not fire and then i get an exception as the Model (.Models.JobViewModel) is not passed to the view that the partialview (JobListings) lives in. basically what im saying is, if i have a myview.aspx with lots of html.RenderPartialView('apartialview') that have forms in them, can i get it so these forms post to their own actions and the main view (with what ever model it inherits) is handled as well. Rather then having all the form submitting code in the main action for the view. am i do this wrong?

• kohana project structure

  - by user176217

  Hello Guys. I'm investigating using Kohana for my next project. The site will consist of user registration (and hence user profiles) where users will have certain privileges. The site will also have an admin section where administrators can go to say block a user or delete a post or look at usage statistics for example. A good comparison site would be a multi-user blog, where each blogger depending on her/his permissions can post/edit/delete blogs...just as an example. Firstly, I'm not sure about how to set up the controller/view structure in order to separate the admin section from the front facing site. I'm using Kohana 3, so I was thinking of a controller structure like so: application/classes/controller/front (front facing)...and application/classes/controller/admin (for administrative section). Or I notice you may be able to use the Route class to set up routes, so I could set up an "admin" route. for example: www.example.com/admin will lead to the admin logon screen. www.example.com --- front controller. As well, can I somehow separate the "Admin" views and controllers from the "front facing" views and controllers like divide them up based on folder structure? Any help is very much appreciated. Thank you.

• Cannot read values from [NSUserDefaults standardUserDefaults] after synchronize

  - by Nonlinearsound

  In the Application Delegate didFinishLaunching method, I am using the following code to build up a new NSDictionary to be used as the new settings bundle for the user: NSNumber *testValue = (NSNumber*)[[NSUserDefaults standardUserDefaults] objectForKey:@"settingsversion"]; if (testValue == nil) { NSNumber *numNewDB = [NSNumber numberWithBool:NO]; NSNumber *numFirstUse = [NSNumber numberWithBool:YES]; NSDate *dateLastStatic = [NSDate date]; NSDate *dateLastMobile = [NSDate date]; NSNumber *numSettingsversion = [NSNumber numberWithFloat:1.0]; NSDictionary *appDefaults = [NSDictionary dictionaryWithObjectsAndKeys: numNewDB, @"newdb", numFirstUse, @"firstuse", numSettingsversion, @"settingsversion", dateLastStatic, @"laststaticupdate", dateLastMobile, @"lastmobileupdate", nil]; [[NSUserDefaults standardUserDefaults] registerDefaults:appDefaults]; [[NSUserDefaults standardUserDefaults] synchronize]; } Later in another ViewController I am trying to read back a value from that same Dictionary, saved as the NSUserDefaults - well at least I thought it would, but I don't get any valid object pointer for the desired member lastUpdate back there: in .h file: NSDate *lastUpdate; in the .m file in a member function: lastUpdate = (NSDate *)[[NSUserDefaults standardUserDefaults] objectForKey:@"laststaticupdate"]; Even, if I print out the content of [NSUserDefaults standardUserDefaults] I only get this: 2010-04-29 15:13:22.322 myApp[4136:207] Content of UserDefaults: <NSUserDefaults: 0x11d340> This leads me to the conclusion that there is no standardUserDefaults dictionary somewhere in memory or it cannot be determined as such a structure. Edit: Every time, I restart the app ión the device, the check for testValue is Nil and I am building up the dictionary again but after one run it should be persistent on the Phone, right? Am I doing something wrong somewhere in between? I have the feeling that I yet didn't really understand how to load and save settings persistent for a certain application on the iPhone. Is there anything I have to do additionally to this? Integrating a settings.bundle in XCode or saving the dictionary manually to the Documents folder? Can someone help me out here? Thanks a lot!

• PHP gettext on Windows

  - by Axsuul

  There's some tutorials out there for gettext (w/ Poedit)... unfortunately, it's mostly for a UNIX environment. And even more unfortunate is that I am running my WAMP server on Windows XP (but I am developing for a UNIX environment) and none of the tutorials can get gettext working properly for me. From the man page (http://us3.php.net/manual/en/book.gettext.php), it appears that it's a different process on a Windows environment. I've tried out some of the solutions in the comments but I still can't get it to work! Please, I've spent many hours on this, hopefully someone can point me in the right direction to get this thing to work! (and I'm sure there are others out there who share my frustration). So far with my setup, I'm only getting output "Hello World!" whereas I should be getting the translated string. Here is my setup/code so far: <?php // test.php if (!defined('LC_MESSAGES')) { define('LC_MESSAGES', 6); } $locale = "deu_DEU"; // apparently the locales are different on a WINDOWS platform putenv("LC_ALL=$locale"); setlocale(LC_ALL, $locale); bindtextdomain("greetings", ".\locale"); textdomain("greetings"); echo _("Hello World"); ?> Folder structure root: C:\Program Files\WampServer 2\www test.php: C:\Program Files\WampServer 2\www\site .po: C:\Program Files\WampServer 2\www\site\locale\deu_DEU\LC_MESSAGES\greetings.po .mo: C:\Program Files\WampServer 2\www\site\locale\deu_DEU\LC_MESSAGES\greetings.mo Please advise! Thanks for your time :)

  - by CHID

  Hi, I have hosted a website. But now my client asks to change it to http://sites.google.com. They hav registered their domain in google. I logged in the site and saw the procedures to create a website from scratch. But is there any way to directly replace the site into google sites. Like, in my site i hav included css files in a folder called stylesheets/css and access it through the link tag. And there are several folders lik that, viz images, scripts etc. 1.Now if i have to transfer it to google sites, where do i create the folders and stuff. I have the priviliges to login to the admin part of the site. 2.And also is there anyway to create database and access it in google sites? 3.Also i see that only html pages can be created. Is there a way to add php pages or other scripting languages? 4.Going forward will google sites be usefull for professional web designing. pls give ideas on whether or not google sites is a good idea to go with

• Multiple forms on a single page

  - by normalocity

  I've got an app that's in invite-only beta right now. Problem is, I can't get the invite system to work. :( On my root page there's a login form (which works just fine), and I'm trying to add a "request invite" form on the same page. I started doing it by putting the form for InviteRequest (ActiveRecord) inside a partial, in the "views" folder for "InviteRequest". The app is definitely calling this partial, but I'm getting the following error: NoMethodError in User_sessions#new Showing app/views/invite_request/_new.html.erb where line #2 raised: undefined method `invite_requests_path' for #<ActionView::Base:0x25b3248> Extracted source (around line #2): 1: <% @invite_request = InviteRequest.new() %> 2: <% form_for @invite_request do |ir| %> 3: <%= ir.label :email %> 4: <%= ir.text_field :email %> 5: <% end %> I also read through the "Multiple Models in a Form" section of my trusty copy of "Agile Web Development with Rails", about maybe doing this with a "fieldset" tag, but not sure if this is the right approach. Thx.

• Django apache-wsgi configuration problem

  - by omat

  Hi, I am trying to get my Django project running on the production server. I setup the environment using pip, so it is identical to the development environment where everything is running fine. The only difference is that I don't use virtualenv on production, because this project is the only one that is going to run on production. Also on production, there is an Nginx reverse proxy to serve static content, and passes dynamic requests to Apache2. The Apache wsgi file is as follows: import sys, os sys.path.append('/home/project/src') os.environ['DJANGO_SETTINGS_MODULE'] = 'settings' import django.core.handlers.wsgi application = django.core.handlers.wsgi.WSGIHandler() When I access the server, I get an import error: ImproperlyConfigured: Error importing middleware middleware: "cannot import name UserProfile" Which refers to the middleware.py under src/ folder which is referred by the settings. But I can import both the middleware and the UserProfile class from within ./manage.py shell prompt. It seems like a problem with paths in wsgi file but I cannot see what. The directory structure is: /home/project /home/project/src (which contains the settings.py, middleware.py and app folders) /home/apache/apache.wsgi Any help is greatly appreciated. Thanks, oMat

• php & mySQL: Storing doc, xls, zip, etc. with limited access and archiving

  - by Devner

  Hi all, In my application, I have a provision for users to upload files like doc, xls, zip, etc. I would like to know how to store these files on my website and have only restricted people access it. I may have a group of people and let only these group access those uploaded files. I know that some may try to just copy the link to the document or the file and pass it to another (non-permitted) user and they can download it. So how can I prevent it? How can I check if the request to download the file was made by a legitimate user who has access to the file? The usernames of the group members are stored in the database along with the document name and location in the database so they can access it. But how do I prevent non-permitted users from being able to access that confidential data in all ways? With the above in mind, how do I store these documents? Do I store the documents in a blob column in the Database or just just let user upload to a folder and merely store the path to the file in the database? The security of the documents is of utmost importance. So any procedure that could facilitate this feature would definitely help. I am not into Object Oriented programming so if you have a simpler code that you would like to share with me, I would greatly appreciate it. Also how do I archive documents that are old? Like say there are documents that are 1 year old and I want to conserve my website space by archiving them but still make them available to the user when they need it. How do I go about this? Thank you.

• Reusing Windows Picture and Fax Viewer process to load a new image from FileSystemWatcher

  - by Cory Larson

  So for an idea for my birthday party I'm setting up a photo booth. I've got software to remotely control the camera and all that, but I need to write a little application to monitor the folder where the pictures get saved and display them. Here's what I've got so far. The issue is that I don't want to launch a new Windows Photo Viewer process every time the FileSystemWatcher sees a new file, I just want to load the latest image into the current instance of the Windows Photo Viewer (or start a new one if one isn't running). class Program { static void Main(string[] args) { new Program().StartWatching(); } public void StartWatching() { FileSystemWatcher incoming = new FileSystemWatcher(); incoming.Path = @"G:\TempPhotos\"; incoming.NotifyFilter = NotifyFilters.LastWrite | NotifyFilters.FileName; incoming.Filter = "*.jpg"; incoming.Created += new FileSystemEventHandler(ShowImage); incoming.EnableRaisingEvents = true; Console.WriteLine("Press \'q\' to quit."); while (Console.Read() != 'q') ; } private void ShowImage(object source, FileSystemEventArgs e) { string s1 = Environment.ExpandEnvironmentVariables("%windir%\\system32\\rundll32.exe "); string s2 = Environment.ExpandEnvironmentVariables("%windir%\\system32\\shimgvw.dll,ImageView_Fullscreen " + e.FullPath); Process.Start(s1, s2); Console.WriteLine("{0} : Image \"{0}\" at {1:t}.", e.ChangeType, e.FullPath, DateTime.Now); } } If you don't have a tried and true solution, a simple push in the right direction would be just as valuable. And FYI, this will be running on a 64-bit Windows 7 machine. Thanks!

• A very weird problem with localization (ASP.NET MVC)

  - by Alex

  I'm using Web Developer 2010. I just created a resource file lang.resx with different values in english. Then I created a lang.FR-fr.resx with French equivalents. However after tryingto compile, I get Error 131 Task could not find "AL.exe" using the SdkToolsPath "C:\Program Files (x86)\Microsoft SDKs\Windows\v7.0A\bin\NETFX 4.0 Tools\" or the registry key "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Microsoft SDKs\Windows\v7.0A". Make sure the SdkToolsPath is set and the tool exists in the correct processor specific location under the SdkToolsPath and that the Microsoft Windows SDK is installed This is so weird! If I remove FR-fr part, it will work, but there will be no translation of course. I went to that directory and found out that I don't have al.exe there. I managed to find it in .NET 2 folder, but after copying it didn't help. It throws an exception. I tried to reinstall .NET 4, to install Windows SDK, and it still doesn't work. Maybe I can somehow get this al.exe file?

• How do I correctly modify a custom cocoa framework?

  - by Septih

  Hello, I'm working with the very-useful ID3 framework in my cocoa project. There's one tiny thing I'd like to modify in it, but I can't seem to get the changes I've made to apply to the built framework. The source code provided with the framework comes with an Xcode project, so I've opened that up and for testings sake put an NSLog(@"hello"); in. It's definetly in a place where it will be called and there are other NSLog() calls in the framework that show up so it's not just console output being supressed. To build the framework once modified I've first cleaned the build folder, made sure that it's actually removed the files, and then built it. Then in the Xcode project I'm using the framework in, I've deleted the old reference and added a new one to the framework that's freshly built. Running my project with the newly build framework doesn't call the modified framework code. I've tried with both the Development and Deployment builds that are part of the framework Xcode project. My gut instinct is that the executable that the framework code is compiled into is being cached somehow. But as I'm fairly unfamiliar with the workings of frameworks, I'm not really sure where to look.

• ASP.NET MVC on GoDaddy Not Working (Not Primary Domain Deployment)

  - by JPrescottSanders

  I am trying to get ASP.NET MVC working on GoDaddy and I'm not having much luck. I have read the post on SO that covers the subject, but I must have a slightly different configuration or must be missing somehting along the way because the main MVC page comes up, but all links seem to fail and no amount of tweaking the URLs seems to get it to work. A little back ground. I have a single hosting plan with many domains pointed to sub folders of the main domain. Basic ASP.NET web forms pages work just fine, but of course I wanted to try and host a sample MVC site in one of these non-primary domains. You can go to the URL here. As you can see this first page comes up, but if you click on Home or About it doesn't work. Clicking on Home creates this link "http://www.jprescottsanders.com/jps/" and clicking on about creates this link "http://www.jprescottsanders.com/jps/Home/About". As you can see JPS sneaks in there, this of course is the sub folder that i place my web app files in. I would like to know if this is a MVC related issue or a GoDaddy issue. I suspect that MVC may want to sit in the root directory of the site, and when it puts the "jps" into the URLs it breaks the routing mechanisms (but this is conjecture). I know Dan said this was possible so I'm hoping he sees this and helps me get to the bottom of this deployment strategy for MVC.

• iPhone: objc_class_name_TTTabStrip symbol not found build error

  - by user187532

  Hello friends, I am trying to implement 'scrollview' effect in 'Tabbar' which has 'TabItems'. I found that the good example is from 'facebook' open source 'TTCatlog' project 'Tabs' section. So i included all the source from it to my project and trying to build it. I have followed the following links to go ahead on this: http://stackoverflow.com/questions/822792/how-to-create-a-horizontal-scrolling-view-on-iphone source: http://github.com/facebook/three20/tree/master/samples/ My calling code is like below: _tabBar1 = [[TTTabStrip alloc] initWithFrame:CGRectMake(10, 68, 300, 28)]; _tabBar1.tabItems = [NSArray arrayWithObjects: [[[TTTabItem alloc] initWithTitle:@"Item 1"] autorelease], [[[TTTabItem alloc] initWithTitle:@"Item 2"] autorelease], [[[TTTabItem alloc] initWithTitle:@"Item 3"] autorelease], [[[TTTabItem alloc] initWithTitle:@"Item 4"] autorelease], [[[TTTabItem alloc] initWithTitle:@"Item 5"] autorelease], [[[TTTabItem alloc] initWithTitle:@"Item 6"] autorelease], [[[TTTabItem alloc] initWithTitle:@"Item 7"] autorelease], [[[TTTabItem alloc] initWithTitle:@"Item 8"] autorelease], [[[TTTabItem alloc] initWithTitle:@"Item 9"] autorelease], [[[TTTabItem alloc] initWithTitle:@"Item 10"] autorelease], nil]; [self.navigationController.view addSubview:_tabBar1]; My project folder as like below: ..../iphone/MyProgram/MyProgram.xcodeproj ..../iphone/Three20/src/Three20.... In my project settings for header search path, I have ../Three20/src But when i try to build it, it throws the following error: "objc_class_name_TTTabStrip symbol not found" "objc_class_name_TTTabItem symbol not found" I see there, all these files (.h and .m) are availbale there. Could someone please help what's wrong there and how do i get rid of this issue and continue working with it?

• ActiveX not working properly with default security settings

  - by Ummar

  I have written an ActiveX control in C# and have made it working using regasm command, and it works fine as long as the security level is set to low.. Then as a next step I have made a .cab installer (ICD - Internet component downloader), and have signed my .cab file and ActiveX .dll file with a test certificate. when I hit the html page from my browser the installation parts works fine with default security settings of IE, but at the end it seems that nothing is installed and a red cross is shown on place of ActiveX. Moreover I have explored the Download Program Files folder under Windows directory, in status column it is showing word "unknown". while it is "installed" for all other activeX. what may be the problem. Moreover if i use the regasm command to register the assembly it works fine, and I have signed the ActiveX but still I have to move the security bar to low in my browser setting? why it is so? then what is the purpose of signing? I have used RegisterServer=yes in my .inf file Please let me know, if some one has gone through this problem already?

• Import package problem in GWT

  - by Krt_Malta

  Hi! I'm developing an app using GWT Eclipse plug-in. (I'm also using GWT Designer but I don't think the problem is here). Previously when I wanted to communicate with a web service I created, I produced the "skeleton" classes from the WSDL url using Sun's wsimport tool. Then I would add the classes generated to a class folder in my Eclipse project. All worked well. However this doesn't seem to be working with GWT. I have these: VideoTutorialServiceService service = new VideoTutorialServiceService(); VideoTutorialService port = service.getVideoTutorialServicePort(); and I have VideoTutorialServiceService and VideoTutorialService underlined in red, the error saying videotutorialservice.VideoTutorialServiceService can not be found in source packages. Check the inheritance chain from your module; it may not be inheriting a required module or a module may not be adding its source path entries properly. .... I googled about it but I got confused. I'm a beginnier in GWT. How can I resolve this please? Thanks and regards, Krt_Malta

  I was told my client's quote form has not been generating very many emails. I have learned that although the form brings you to a confirmation page, the information never reaches the recipient. I have altered the code so it goes to my office email for testing purposes. If I post code for the form elements below, would someone be able to spot what the problem might be? Thank you very much!

• Why are mercurial subrepos behaving as unversioned files in eclipse AND torotoiseHG

  - by noam

  I am trying to use the subrepo feature of mercurial, using the mercurial eclipse plugin\tortoiseHG. These are the steps I took: Created an empty dir /root cloned all repos that I want to be subrepos inside this folder (/root/sub1, /root/sub2) Created and added the .hgsub file in the root repo /root/.hgsub and put all the mappings of the sub repos in it using tortoiseHG, right clicked on /root and selected create repository here again with tortoise, selected all the files inside /root and added them to to the root repo commited the root repo pushed the local root repo into an empty repo I have set up on kiln Then, I pulled the root repo in eclipse, using import-mercurial. Now I see that all the subrepos appear as though they are unversioned (no "orange cylinder" icon next to their corresponding folders in the eclipse file explorer). Furthermore, when I right click on one of the subrepos, I don't get all the hg commands in the "team" menu as I usually get, with root projects - no "pull", "push" etc. Also, when I made a change to a file in a subrepo, and then "committed" the root project, it told me there were no changes found. I see the same behavior also in tortoiseHG - When I am browsing files under /root, the files belonging directly to the root repo have an small icon (a V sign) on them marking they are version controlled, while the subrepos' folders aren't marked as such. Am I doing something wrong, or is it a bug?
