  • How do I programatically add an article page to a sharepoint site?

    - by soniiic
    I've been given the task of content migration from another CMS system to SharePoint 2010. The data in the old system is fairly easy to capture and the page hierarchy is simple so I'm not worried about that. However, I am completely flummoxed about how to even create a page in code. I'm using the Microsoft.SharePoint.Client namespace as I do not have sharepoint installed on my system and am wanting to code this up as a console application and so I'm using I'm using ClientContext. (On the other hand, I am willing to go into other solutions if necessary). My end-game: To get a page uploaded into some folder hierarchy which uses a master page, has the page title in a header web part, and a big ol' content-editable web part in the body so any user can come along and edit the content. Things I've tried so far: Using FileCollection.Add() to add an aspx file to the folder "Site Pages". This renders the html in the browser but doesn't enable any features for the user to edit the page Using ListItemCollection.Add() to add a page to the site, but I didn't know what fields I needed. Also I remember it came up with a runtime error saying I should use FileCollection.Add() Uploading to 'Site Pages' instead of 'Pages' So many others... ow my head :( The only plausible thing I can see on the net is to use the PublishingPage type along with PublishingWeb. However, PublishingWeb can only be constructed from an SPWeb object which requires me to be actually hosting the sharepoint application on my workstation. If anyone can lend a hand that would be greatly appreciated :)

  • How can I remove certain characters from inside angle-brackets, leaving the characters outside alone

    - by Iain Fraser
    Edit: To be clear, please understand that I am not using Regex to parse the html, that's crazy talk! I'm simply wanting to clean up a messy string of html so it will parse Edit #2: I should also point out that the control character I'm using is a special unicode character - it's not something that would ever be used in a proper tag under any normal circumstances Suppose I have a string of html that contains a bunch of control characters and I want to remove the control characters from inside tags only, leaving the characters outside the tags alone. For example Here the control character is the numeral "1". Input The quick 1<strong>orange</strong> lemming <sp11a1n 1class1='jumpe111r'11>jumps over</span> 1the idle 1frog Desired Output The quick 1<strong>orange</strong> lemming <span class='jumper'>jumps over</span> 1the idle 1frog So far I can match tags which contain the control character but I can't remove them in one regex. I guess I could perform another regex on my matches, but I'd really like to know if there's a better way. My regex Bear in mind this one only matches tags which contain the control character. <(([^>])*?`([^>])*?)*?> Thanks very much for your time and consideration. Iain Fraser

  • How to convert a printer driver to a stand-alone console application which can generate a printer fi

    - by Thorbjørn Ravn Andersen
    I have a situation where the only way to generate a certain datafile is to print it manually to FILE: under Windows and save it in a file for further processing. I would really like to have a small stand-alone program which embeds this binary printer driver so I can run it from a batch file and have it generate that binary file for me, as we can then fully automate the "save file in Visio, 'print' it and upload it to the final destination and trigger a remote test". Is this possible with a suitable Windows SDK? I am a Java programmer, so I do not know Visual Studio and the possibilities with MSDN - yet! - but I'd appreciate pointers. EDIT: I have the installation files for that printer driver, both 32 and 64 bit. Older versions may include a 16 bit driver. EDIT: The "print to FILE:" functionality is just what was recommended by the documentation. I have played a little bit with using the LPR-protocol to see what it can do. I'd still prefer the "invoke small binary" approach.

  • How can I do rapid application development with ASP.NET MVC?

    - by Erik Forbes
    I've been given a short amount of time (~80 hours to start with) to replace an existing Access database with a full-blown SQL + Web system, and I'm enumerating my options. I would like to use ASP.NET MVC, but I'm unsure of how to use it effectively with my short timetable. For the database backend I'll be using Linq to SQL as it's a product I already know and can get something working with it quickly. Does anyone have any experience with using ASP.NET MVC in this way and can share some insight? Edit: The reason I've been interested in ASP.NET MVC is because I know (100% confirmed) that there will be more work to do after this first round, and I'd like my maintenance work to be as easy as possible. In my experience Webforms applications tend to break down over repeated maintenance, despite discipline. Maybe there's a middle ground? How difficult would it to be for me to, say, build the app with Webforms, then migrate it to MVC later when I have more time budgeted to the project? Edit 2: Further background: the Access application I'm replacing is used in some capacity by everyone in the building, and since it was upgraded from Access 98 to 2003 it's been crashing daily, causing hours of lost productivity as people have to re-enter data since the last backup. This is the reason for the short amount of time - this is a critical business function, and they can't afford to keep re-entering data on a daily basis.

  • Creating a draft version of the page before publishing in Drupal 6?

    - by Marco
    I've been looking for a good way to handle revisions in Drupal, but I am yet to succeed. For some reason there is no built in way to save a draft (that I've found so far), and the modules I've tried so far do not seem to fully work. First I tried save_as_draft, which seemed to do almost what I wanted, and if I'm not mistaken, also handles CCK fields. Sadly it seems to be broken somehow, so I can't edit a page once I've saved it as a draft.. maybe I could fix it by going through the code, but that would not be my preferred solution. The other module I tried is aptly named draft, but from what I can tell, this module only handles the title and body fields, and does this in a way that appear odd to me. Is there some common practice to solve this? I couldn't imagine that nobody had to solve this before, but I haven't found any good solution to it yet. Clarification I need this functionality for already existing content, that is, I want to be able to create and edit a draft version of an already published page, while the "old" version would still be available to anonymous users.

  • When I try to run vim in command line I get Python errors

    - by Eduan
    When I try running vim in the Terminal (so as to follow @romainl's suggestion in my other question) I get lots of Python errors, which all boil down to: IOError: invalid Python installation: unable to open /usr/include/python2.7/pyconfig.h (No such file or directory) Why is this? I can use Python or Sublime Text even, without any problems. The full list of errors is the following: Traceback (most recent call last): File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site.py", line 565, in <module> File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site.py", line 547, in main File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site.py", line 278, in addusersitepackages File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site.py", line 253, in getusersitepackages File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site.py", line 243, in getuserbase File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/sysconfig.py", line 523, in get_config_var File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/sysconfig.py", line 419, in get_config_vars File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/sysconfig.py", line 298, in _init_posix IOError: invalid Python installation: unable to open /usr/include/python2.7/pyconfig.h (No such file or directory) Extra info: I am on Mac OS X Mountain Lion (OS 10.8) EDIT: I tried @BobDunakey idea with no success, the idea was to use sudo.

  • Skip Checkout in Magento for a downloadable product

    - by Aaron Newton
    Hello Magento boffins. I am using Magento to build an eBooks site. For the release, we plan to have a number of free downloadable books. We were hoping that it would be possible to use the normal Magento 'catalog' functionality to add categories with products underneath. However, since these are free downloadable products, it doesn't really make sense to send users through the checkout when they try to download. Does anyone know of a way to create a free downloadable product which bypasses the checkout altogether? I have noticed that there is a 'free sample' option for downloadable products, but I would prefer not to use this if I can as I plan to use this field for its intended purpose when I add paid products. [EDIT] I have noticed that some of you have voted this question down for 'lack of question clarity'. For clarity, I want: to know if it is possible to create a downloadable product in Magento which doesn't require users to go through the usual checkout process (since it is free) and which is not the 'Free Sample' field of a downloadable product Unfortunately I don't think I can ask this any more eloquently. [/EDIT]

  • Why are changes to coffeescript files not being compiled when my Rails 3.2.0 app is in development mode?

    - by ben
    Normally, any changes I make to .js.coffee files in my Rails 3.2.0 app in development mode take effect when I refresh the page. All of a sudden, this is not happening. If I do rake assets:precompile, then the changes are shown, but then if I do rake assets:clean they go back to not being shown. What is causing this? Edit: Restarting the server makes the changes show. Why isn't this happening automatically as before? Edit: Here is my development.rb Myapp::Application.configure do # Settings specified here will take precedence over those in config/application.rb # In the development environment your application's code is reloaded on # every request. This slows down response time but is perfect for development # since you don't have to restart the web server when you make code changes. config.cache_classes = false # Log error messages when you accidentally call methods on nil. config.whiny_nils = true # Show full error reports and disable caching config.consider_all_requests_local = true config.action_controller.perform_caching = false # Don't care if the mailer can't send config.action_mailer.raise_delivery_errors = false # Print deprecation notices to the Rails logger config.active_support.deprecation = :log # Only use best-standards-support built into browsers config.action_dispatch.best_standards_support = :builtin # Raise exception on mass assignment protection for Active Record models config.active_record.mass_assignment_sanitizer = :strict # Log the query plan for queries taking more than this (works # with SQLite, MySQL, and PostgreSQL) config.active_record.auto_explain_threshold_in_seconds = 0.5 # Do not compress assets config.assets.compress = false # Expands the lines which load the assets config.assets.debug = true config.action_mailer.default_url_options = { :host => 'localhost:3000' } config.log_level = :warn end

  • Adding a ServiceReference programmatically during async postback

    - by Oliver
    Is it possible to add a new ServiceReference instance to the ScriptManager on the Page during an asynchronous postback so that subsequently I can use the referenced web service through client side script? I'm trying to do this inside a UserControl that sits inside a Repeater, that's why adding the ScriptReference programmatically during Page_Load does not work here. EDIT 2: This is the code I call from my UserControl which does not do what I expect (adding the ServiceReference to the ScriptManager during the async postback): private void RegisterWebservice(Type webserviceType) { var scm = ScriptManager.GetCurrent(Page); if (scm == null) throw new InvalidOperationException("ScriptManager needed on the Page!"); scm.Services.Add(new ServiceReference("~/" + webserviceType.Name + ".asmx")); } My goal is for my my UserControl to be as unobtrusive to the surrounding application as possible; otherwise I would have to statically define the ServiceReference in a ScriptManagerProxy on the containing Page, which is not what I want. EDIT: I must have been tired when I wrote this post... because I meant to write ServiceReference not ScriptReference. Updated the text above accordingly. Now I have: <asp:ScriptManagerProxy runat="server" ID="scmProxy"> <Services> <asp:ServiceReference Path="~/UsefulnessWebService.asmx" /> </Services> </asp:ScriptManagerProxy> but I want to register the webservice in the CodeBehind.

  • .NET WebBrowser control with Adobe SVG Viewer

    I'm having problems with SVG files loading in a .NET 2.0 WebBrowser control. If I create a new WinForms application project, drag a WebBrowser control and a button onto the Form1.cs design surface, and add a line to the button's on-click handler to set the Url property of the WebBrowser control to an SVG file, I get two IE script errors at runtime (as in, the dialog you get when there is a Javascript problem). The only line of code I'm writing is therefore: webBrowser1.Url = new Uri(@"http://wiki.allegro.cc/pub/f/fb/Grozilla.svg"); This SVG file loads fine if I browse directly to the link with IE; the errors I get via my test app are: line 2, char 1, error: Invalid character, followed by line 1, char 1, error: Object expected (assuming I answer yes to the prompt to 'continue running scripts on this page'). I'm using IE 7.0.5730.13, Adobe SVG Viewer 3.03 build 94, Visual Studio 2008. Can anyone replicate this? Has anyone seen it/got any idea how to fix it? (edit: previously setting the URL in the constructor for the purposes of the example, but this raised the question of whether or not the control had finished initialising, so have changed the example to use a button - the problem still occurs. This bug originally appeared in production code so the example program I wrote was an attempt to isolate the issue and reproduce it as simply as possible.) (edit 2: having tested on several different machines, this problems seems to be related to IE7 - run IE6, and everything works fine.)

  • UI Design, incase of numerous situations

    - by The King
    Hi... I'm creating a web form, where in there are around 12-15 Input Fields... You can have a look at the screen and The request is such that depending on the data the user selects in the Gridview and the DropDown list, the appropriate Textboxes and CheckBoxes needs to be displayed. Some times the conditions are very direct, like when the DDL value is "ABC", get only paid amount from the user. Sometime they are so complex like... IF DDL is "DEF" and Selected GPMS value is between 1000-2000, calculate the values of allowed, paid etc (using some formula) and the focus should be directed to Page No Field, leaving the other fields open incase user wants to edit... There are around 10-15 conditions like this. As this was done through agile, conditions were being added as and when, and wherever it feels appropriate (DDL on change Event, GridView on selecting change event etc... etc..) After completion, now I see the code has become a big chuck, is growing unmanageably... Now, I'm planning to clear this... From you experience, what you think is the best way to handle this. There is a possibility to add more conditions like this in future... Please let me know, incase you need more information. I'm currently developing this app in C# .Net WindowsForms Edit: Currently there are only three items (The Datagrid, the DDL, the OverrideAmt CheckBox) that change the way other fields behave... Almost all of the conditions will fall between the two situations I mentioned... Mostly they belong to "Enabling/Disabling".. "Setting of Values"... and "Changing Focus" or any combination of these.

  • Replacing accented/umlauted characters with their unadorned counterparts in C# [closed]

    - by Andrew Rollings
    Duplicate of 249087 I have a bunch of user generated addresses that may contain characters with diacritic marks. What is the most effective (i.e. generic) way (apart from a straightforward replace) to automatically convert any such characters to their closest English equivalent? E.g. any of àâãäå would become a æ would become the two separate letters ae ç would become c any of èéêë would become e etc. for all possible letter variations (preferably without having to find and encode lookups for each diacritic form of the letter). (Note: I have to pass these addresses on to third party software that is incapable of printing anything other than English characters. I'd rather the software was capable of handling them, but I have no control over that.) EDIT: Never mind... Found the answer [here][2]. It showed up in the "Related" section to the right of the question after I posted, but not in my prior search or as a pre-post suggestion. Hmm. I added the 'diacritics' tag to the other question in any case. EDIT 2: Jeez! Who voted this -1 after I closed it?

  • WPF - Why doesn't Microsoft supply a decent set of most-used controls ?

    - by IUsedToBeAPygmy
    I've been playing with WPF for some months now, and I quite like it. But one of the things I don't get is why MS doesn't put a little more effort in helping developers by supplying basic controls, and I need to get this off my chest :) For example, I figure most applications somewhere will need to let you edit some properties - for configuration or whatever. What would be the most used types in a proprety-grid editor ? text numbers (byte, float/double, int, etc) colors ....etc. So why isn't there even something as simple as a control to edit numbers ? Like a generic NumericUpDown control that allows you to type in numbers (no text, no pasting invalid input) or spin them up/down according to some given rules (decimal, floating point, min/maxvalue) ? Why isn't there a generic colorpicker, so people get the same user-experience in every application ? Why isn't there a standard implementation of a SearchTextBox, a BreadCrumb-control, or all these other standard control types users have gotten accustomed to the last 10 years ? (..but at least they DID have the time to implement a generic splashscreen - because everyone knows that greatly increases user-productivity....) The well-known ideal is always to give people the same user-experience over different applications. So even if some of those controls would be easy to make - it would be preferred to have one version over different applications. I see people all over the internet trying to do the same stuff over and over again. Okay, so MS started a WPF Toolkit project on Codeplex that tries to implement some controls, but only did so half-heartedly and is completely dead by now (last update of the roadmap dates back to Mar 21 2009). The result of this is that a lot of people starting a WPF-project end up spending a lot of time on trying to figure out how to create some generic controls and get really frustrated. Wasn't the mantra "Developers, developers, developers!" ..? /Rant

  • How do I apply a "template" or "skeleton" of code in C# here?

    - by Scott Stafford
    In my business layer, I need many, many methods that follow the pattern: public BusinessClass PropertyName { get { if (this.m_LocallyCachedValue == null) { if (this.Record == null) { this.m_LocallyCachedValue = new BusinessClass( this.Database, this.PropertyId); } else { this.m_LocallyCachedValue = new BusinessClass( this.Database, this.Record.ForeignKeyName); } } return this.m_LocallyCachedValue; } } I am still learning C#, and I'm trying to figure out the best way to write this pattern once and add methods to each business layer class that follow this pattern with the proper types and variable names substituted. BusinessClass is a typename that must be substituted, and PropertyName, PropertyId, ForeignKeyName, and m_LocallyCachedValue are all variables that should be substituted for. Are attributes usable here? Do I need reflection? How do I write the skeleton I provided in one place and then just write a line or two containing the substitution parameters and get the pattern to propagate itself? EDIT: Modified my misleading title -- I am hoping to find a solution that doesn't involve code generation or copy/paste techniques, and rather to be able to write the skeleton of the code once in a base class in some form and have it be "instantiated" into lots of subclasses as the accessor for various properties. EDIT: Here is my solution, as suggested but left unimplemented by the chosen answerer. // I'll write many of these... public BusinessClass PropertyName { get { return GetSingleRelation(ref this.m_LocallyCachedValue, this.PropertyId, "ForeignKeyName"); } } // That all call this. public TBusinessClass GetSingleRelation<TBusinessClass>( ref TBusinessClass cachedField, int fieldId, string contextFieldName) { if (cachedField == null) { if (this.Record == null) { ConstructorInfo ci = typeof(TBusinessClass).GetConstructor( new Type[] { this.Database.GetType(), typeof(int) }); cachedField = (TBusinessClass)ci.Invoke( new object[] { this.Database, fieldId }); } else { var obj = this.Record.GetType().GetProperty(objName).GetValue( this.Record, null); ConstructorInfo ci = typeof(TBusinessClass).GetConstructor( new Type[] { this.Database.GetType(), obj.GetType()}); cachedField = (TBusinessClass)ci.Invoke( new object[] { this.Database, obj }); } } return cachedField; }

  • How do I get many, but not all, property values from View to Presenter in WebFormsMvp?

    - by andrej351
    Hey there, What is the best way to get a number of property values of a business object from the View to the Presenter in a WebFormsMvp page? Here is what i propose: The scenario is, I have a business object called Quote which i would like to load form the database, edit and then save. The Quote class has heaps of properties on it. The form is concerned with about 20 of these properties. I have existing methods to load/save a Quote object to/from the database. I now need to wire this all together. So, in the View_Load handler on my presenter i intend to do something like this: public void View_Load(object sender, EventArgs e) { View.Model.Quote = quoteService.Read(quoteId); } And then bind all my controls as follows: <asp:TextBox ID="TotalPriceTextBox" runat="server" Text="<%# Model.Quote.TotalPrice %>" /> All good, the data is on the screen. The user then makes a bunch of changes and hits a "Submit" button. Here is where I'm unsure. I create a class called QuoteEventArgs exposing the 20 properties the form is able to edit. When the View raises the Submit button's event, I set these properties to the values of the controls in the code behind. Then raise the event for the presenter to respond to. The presenter re-loads the Quote object from the database, sets all the properties and saves it to the database. Is this the right way to do this? If not, what is? Cheers, Andrej.

  • Capturing mouse events for specific dom/web elements in QT

    - by Red Serpent
    Hi I would like to know if it is possible in QTWebKit to install an event filter or capture events that occur from specific Dom elements. For example, my webview is showing a webpage that has text, images and an edit box, I want to disable the right-clicking and highlighting functionality on the text and images but at the same time when the user right-clicks inside the edit box, I want to display my context menu. I am not sure where should I install my event filter, in QwebView or QwebPage... currently this is what I'm using: MainWindow::MainWindow() { centralWidget = new WebView(this); setCentralWidget(centralWidget); centralWidget->webView->installEventFilter(this); //No mouse events are rising on QWebPage //centralWidget->webView->page()->installEventFilter(this); } As its clear in the code above, when installing an EventFilter on QwebPage, I never receive any QMouseEvents, not by moving clicking or releasing any mouse buttons. While when setting it to filter events from QWebView it works fine. I am really interested with the first part of my question as to how handle Dom elements differently. How can I achieve such goal? Regards

  • Where to Store ID Field In Silverlight

    - by Blake Blackwell
    I am trying to use the MVVM pattern, and I am wondering where I place an ID value. Do I create a TextBlock that has its visibility property set to collapsed? Or is there a better place to store this kind of data? Currently the command parameter is set to: CommandParameter="{Binding ElementName=Name,Path=Text}" But I'd rather it be something like: CommandParameter="{Binding ElementName=Id,Path=Text}" I'm totally up for suggestions on what the best way there is to do this, since I'm new to this pattern and presentation language. <ListBox x:Name="MyListBox" ItemsSource="{Binding MyData, Mode=TwoWay}" BorderThickness="0"> <ListBox.ItemTemplate> <DataTemplate> <StackPanel Orientation="Horizontal"> <CheckBox x:Name="Visible" IsChecked="{Binding Visible, Mode=TwoWay}" Command="{Binding ElementName=MyListBox, Path=DataContext.MyCommand}" CommandParameter="{Binding ElementName=Name,Path=Text}" /> <TextBlock Text="{Binding Name}" /> </StackPanel> </DataTemplate> </ListBox.ItemTemplate> </ListBox> EDIT: Option 1 <CheckBox x:Name="Visible" IsChecked="{Binding Visible, Mode=TwoWay}" Command="{Binding ElementName=MyListBox, Path=DataContext.MyCommand}" CommandParameter="{Binding Id}" /> This option gives me just the Id, which is useful in many situations. EDIT: Option 2 <CheckBox x:Name="Visible" IsChecked="{Binding Visible, Mode=TwoWay}" Command="{Binding ElementName=MyListBox, Path=DataContext.MyCommand}" CommandParameter="{Binding}" /> This option gives me the full model, which is even useful for my particular situation.

  • Python 3.0 IDE - Komodo and Eclipse both flaky?

    - by victorhooi
    heya, I'm trying to find a decent IDE that supports Python 3.x, and offers code completion/in-built Pydocs viewer, Mercurial integration, and SSH/SFTP support. Anyhow, I'm trying Pydev, and I open up a .py file, it's in the Pydev perspective and the Run As doesn't offer any options. It does when you start a Pydev project, but I don't want to start a project just to edit one single Python script, lol, I want to just open a .py file and have It Just Work... Plan 2, I try Komodo 6 Alpha 2. I actually quite like Komodo, and it's nice and snappy, offers in-built Mercurial support, as well as in-built SSH support (although it lacks SSH HTTP Proxy support, which is slightly annoying). However, for some reason, this refuses to pick up Python 3. In Edit-Preferences-Languages, there's two option, one for Python and Python3, but the Python3 one refuses to work, with either the official Python.org binaries, or ActiveState's own ActivePython 3. Of course, I can set the "Python" interpreter to the 3.1 binary, but that's an ugly hack and breaks Python 2.x support. So, does anybody who uses an IDE for Python have any suggestions on either of these accounts, or can you recommend an alternate IDE for Python 3.0 development? Cheers, Victor

  • C#: Is it possible to use expressions or functions as keys in a dictionary?

    - by Svish
    Would it work to use Expression<Func<T>> or Func<T> as keys in a dictionary? For example to cache the result of heavy calculations. For example, changing my very basic cache from a different question of mine a bit: public static class Cache<T> { // Alternatively using Expression<Func<T>> instead private static Dictionary<Func<T>, T> cache; static Cache() { cache = new Dictionary<Func<T>, T>(); } public static T GetResult(Func<T> f) { if (cache.ContainsKey(f)) return cache[f]; return cache[f] = f(); } } Would this even work? Edit: After a quick test, it seems like it actually works. But I discovered that it could probably be more generic, since it would now be one cache per return type... not sure how to change it so that wouldn't happen though... hmm Edit 2: Noo, wait... it actually doesn't. Well, for regular methods it does. But not for lambdas. They get various random method names even if they look the same. Oh well c",)

    I could create a grid with telerik mvc <% Html.Telerik().Grid(Model) .Name("ProductGrid") .Columns(columns => { columns.Bound(h => h.ProductName).Width("34%"); columns.Bound(h => h.Description).Width("60%"); columns.Bound(h => h.ProductID).Format(Html.ImageLink("Edit", "Products", new { Id = "{0}" }, "/Content/images/icon_edit.gif", "", new { Id = "edit{0}" }, null).ToString()).Encoded(false).Title("").Sortable(false).Width("3%"); columns.Bound(h => h.ProductID).Format(Html.ImageLink("Delete", "Products", new { Id = "{0}" }, "/Content/images/icon_delete.gif", "", new { onclick = string.Format("return confirm('Are you sure to delete this add on?');") },null).ToString()).Encoded(false).Title("").Sortable(false).Width("3%"); }) .EnableCustomBinding(true) .DataBinding(databinding => databinding.Ajax().Select("_Index", "ProductGrid")) .Pageable(settings => settings.Total((int)ViewData["TotalPages"]) .PageSize(10)) .Sortable() .Render(); %> but I need to add a serial number column in telerik grid.How can i do this?

  • Writing a JavaScript zip code validation function

    - by mkoryak
    I would like to write a JavaScript function that validates a zip code, by checking if the zip code actually exists. Here is a list of all zip codes: http://www.census.gov/tiger/tms/gazetteer/zips.txt (I only care about the 2nd column) This is really a compression problem. I would like to do this for fun. OK, now that's out of the way, here is a list of optimizations over a straight hashtable that I can think of, feel free to add anything I have not thought of: Break zipcode into 2 parts, first 2 digits and last 3 digits. Make a giant if-else statement first checking the first 2 digits, then checking ranges within the last 3 digits. Or, covert the zips into hex, and see if I can do the same thing using smaller groups. Find out if within the range of all valid zip codes there are more valid zip codes vs invalid zip codes. Write the above code targeting the smaller group. Break up the hash into separate files, and load them via Ajax as user types in the zipcode. So perhaps break into 2 parts, first for first 2 digits, second for last 3. Lastly, I plan to generate the JavaScript files using another program, not by hand. Edit: performance matters here. I do want to use this, if it doesn't suck. Performance of the JavaScript code execution + download time. Edit 2: JavaScript only solutions please. I don't have access to the application server, plus, that would make this into a whole other problem =)

  • Which key value store is the most promising/stable?

    - by Mike Trpcic
    I'm looking to start using a key/value store for some side projects (mostly as a learning experience), but so many have popped up in the recent past that I've got no idea where to begin. Just listing from memory, I can think of: CouchDB MongoDB Riak Redis Tokyo Cabinet Berkeley DB Cassandra MemcacheDB And I'm sure that there are more out there that have slipped through my search efforts. With all the information out there, it's hard to find solid comparisons between all of the competitors. My criteria and questions are: (Most Important) Which do you recommend, and why? Which one is the fastest? Which one is the most stable? Which one is the easiest to set up and install? Which ones have bindings for Python and/or Ruby? Edit: So far it looks like Redis is the best solution, but that's only because I've gotten one solid response (from ardsrk). I'm looking for more answers like his, because they point me in the direction of useful, quantitative information. Which Key-Value store do you use, and why? Edit 2: If anyone has experience with CouchDB, Riak, or MongoDB, I'd love to hear your experiences with them (and even more so if you can offer a comparative analysis of several of them)

  • Google App Engine Needs Index Error

    - by Andrew Johnson
    I am currently getting a needs index error on my app engine app: http://www.gaiagps.com/wiki/home. I believe this index should have been created automatically by my index.yaml file (see below). Googling a bit, I think I just need to wait for my index to be built. Is this correct, or do I need to do something manually? Is there some sort of index-building queue? My tables are very, very small right now. EDIT: I added the line "indexes:" to my app.yaml, and now app engine reports the index is building, so I think this is fixed. It's weird that this file was wrong considering I've never touched it. indexes: # AUTOGENERATED # This index.yaml is automatically updated whenever the dev_appserver # detects that a new type of query is run. If you want to manage the # index.yaml file manually, remove the above marker line (the line # saying "# AUTOGENERATED"). If you want to manage some indexes # manually, move them above the marker line. The index.yaml file is # automatically uploaded to the admin console when you next deploy # your application using appcfg.py. - kind: Revision properties: - name: name - name: created The app works on my dev server, but not in production. However, on my dev console, I have noticed this error (EDIT: THIS ERROR IS GONE NOW THAT I ADDED indexes: to the app.yaml file above): ERROR 2009-10-18 04:46:51,908 dev_appserver_index.py:176] Error parsing /gaiagps.com/index.yaml: 'NoneType' object is not callable in "<string>", line 13, column 3: - kind: Revision ^
