  • Why 10675199.02:48:05.4775807 TimeSpan Maximum for CompilationSection?

    - by Alex
    I was looking at the metadata for System.Web.Configuration.CompilationSection, and noticed the following attribute on the TimeSpan BatchTimeout property: [TimeSpanValidator(MinValueString = "00:00:00", MaxValueString = "10675199.02:48:05.4775807")] Could someone explain why this is the allowed max value? TimeSpan itself has an upper limit, so why would there be another value validation, and why this number?

  • Application Performance Episode 2: Announcing the Judges!

    - by Michaela Murray
    The story so far… We’re writing a new book for ASP.NET developers, and we want you to be a part of it! If you work with ASP.NET applications, and have top tips, hard-won lessons, or sage advice for avoiding, finding, and fixing performance problems, we want to hear from you! And if your app uses SQL Server, even better – interaction with the database is critical to application performance, so we’re looking for database top tips too. There’s a Microsoft Surface apiece for the person who comes up with the best tip for SQL Server and the best tip for .NET. Of course, if your suggestion is selected for the book, you’ll get full credit, by name, Twitter handle, GitHub repository, or whatever you like. To get involved, just email your nuggets of performance wisdom to [email protected] – there are examples of what we’re looking for and full competition details at Application Performance: The Best of the Web. Enter the judges… As mentioned in my last blogpost, we have a mystery panel of celebrity judges lined up to select the prize-winning performance pointers. We’re now ready to reveal their secret identities! Judging your ASP.NET  tips will be: Jean-Phillippe Gouigoux, MCTS/MCPD Enterprise Architect and MVP Connected System Developer. He’s a board member at French software company MGDIS, and teaches algorithms, security, software tests, and ALM at the Université de Bretagne Sud. Jean-Philippe also lectures at IT conferences and writes articles for programming magazines. His book Practical Performance Profiling is published by Simple-Talk. Nik Molnar,  a New Yorker, ASP Insider, and co-founder of Glimpse, an open source ASP.NET diagnostics and debugging tool. Originally from Florida, Nik specializes in web development, building scalable, client-centric solutions. In his spare time, Nik can be found cooking up a storm in the kitchen, hanging with his wife, speaking at conferences, and working on other open source projects. Mitchel Sellers, Microsoft C# and DotNetNuke MVP. Mitchel is an experienced software architect, business leader, public speaker, and educator. He works with companies across the globe, as CEO of IowaComputerGurus Inc. Mitchel writes technical articles for online and print publications and is the author of Professional DotNetNuke Module Programming. He frequently answers questions on StackOverflow and MSDN and is an active participant in the .NET and DotNetNuke communities. Clive Tong, Software Engineer at Red Gate.

  • Implementing a modern web application with Web API on top of old services

    - by Gaui
    My company has many WCF services which may or may not be replaced in the near future. The old web application is written in WebForms and communicates straight with these services via SOAP and returns DataTables. Now I am designing a new modern web application in a modern style, an AngularJS client which communicates with an ASP.NET Web API via JSON. The Web API then communicates with the WCF services via SOAP. In the future I want to let the Web API handle all requests and go straight to the database, but because the business logic implemented in the WCF services is complicated it's going to take some time to rewrite and replace it. Now to the problem: I'm trying to make it easy in the near future to replace the WCF services with some other data storage, e.g. another endpoint, database or whatever. I also want to make it easy to unit test the business logic. That's why I have structured the Web API with a repository layer and a service layer. The repository layer has a straight communication with the data storage (WCF service, database, or whatever) and the service layer then uses the repository (Dependency Injection) to get the data. It doesn't care where it gets the data from. Later on I can be in control and structure the data returned from the data storage (DataTable to POCO) and be able to test the logic in the service layer with some mock repository (using Dependency Injection). Below is some code to explain where I'm going with this. But my question is, does this all make sense? Am I making this overly complicated and could this be simplified in any way possible? Does this simplicity make this too complicated to maintain? My main goal is to make it as easy as possible to switch to another data storage later on, e.g. an ORM and be able to test the logic in the service layer. And because the majority of the business logic is implemented in these WCF services (and they return DataTables), I want to be in control of the data and the structure returned to the client. Any advice is greatly appreciated. Update 20/08/14 I created a repository factory, so services would all share repositories. Now it's easy to mock a repository, add it to the factory and create a provider using that factory. Any advice is much appreciated. I want to know if I'm making things more complicated than they should be. So it looks like this: 1. Repository Factory public class RepositoryFactory { private Dictionary<Type, IServiceRepository> repositories; public RepositoryFactory() { this.repositories = new Dictionary<Type, IServiceRepository>(); } public void AddRepository<T>(IServiceRepository repo) where T : class { if (this.repositories.ContainsKey(typeof(T))) { this.repositories.Remove(typeof(T)); } this.repositories.Add(typeof(T), repo); } public dynamic GetRepository<T>() { if (this.repositories.ContainsKey(typeof(T))) { return this.repositories[typeof(T)]; } throw new RepositoryNotFoundException("No repository found for " + typeof(T).Name); } } I'm not very fond of dynamic but I don't know how to retrieve that repository otherwise. 2. Repository and service // Service repository interface // All repository interfaces extend this public interface IServiceRepository { } // Invoice repository interface // Makes it easy to mock the repository later on public interface IInvoiceServiceRepository : IServiceRepository { List<Invoice> GetInvoices(); } // Invoice repository // Connects to some data storage to retrieve invoices public class InvoiceServiceRepository : IInvoiceServiceRepository { public List<Invoice> GetInvoices() { // Get the invoices from somewhere // This could be a WCF, a database, or whatever using(InvoiceServiceClient proxy = new InvoiceServiceClient()) { return proxy.GetInvoices(); } } } // Invoice service // Service that handles talking to a real or a mock repository public class InvoiceService { // Repository factory RepositoryFactory repoFactory; // Default constructor // Default connects to the real repository public InvoiceService(RepositoryFactory repo) { repoFactory = repo; } // Service function that gets all invoices from some repository (mock or real) public List<Invoice> GetInvoices() { // Query the repository return repoFactory.GetRepository<IInvoiceServiceRepository>().GetInvoices(); } }

  • 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 =)

  • Logging errors caused by exceptions deep in the application

    - by Kaleb Pederson
    What are best-practices for logging deep within an application's source? Is it bad practice to have multiple event log entries for a single error? For example, let's say that I have an ETL system whose transform step involves: a transformer, pipeline, processing algorithm, and processing engine. In brief, the transformer takes in an input file, parses out records, and sends the records through the pipeline. The pipeline aggregates the results of the processing algorithm (which could do serial or parallel processing). The processing algorithm sends each record through one or more processing engines. So, I have at least four levels: Transformer - Pipeline - Algorithm - Engine. My code might then look something like the following: class Transformer { void Process(InputSource input) { try { var inRecords = _parser.Parse(input.Stream); var outRecords = _pipeline.Transform(inRecords); } catch (Exception ex) { var inner = new ProcessException(input, ex); _logger.Error("Unable to parse source " + input.Name, inner); throw inner; } } } class Pipeline { IEnumerable<Result> Transform(IEnumerable<Record> records) { // NOTE: no try/catch as I have no useful information to provide // at this point in the process var results = _algorithm.Process(records); // examine and do useful things with results return results; } } class Algorithm { IEnumerable<Result> Process(IEnumerable<Record> records) { var results = new List<Result>(); foreach (var engine in Engines) { foreach (var record in records) { try { engine.Process(record); } catch (Exception ex) { var inner = new EngineProcessingException(engine, record, ex); _logger.Error("Engine {0} unable to parse record {1}", engine, record); throw inner; } } } } } class Engine { Result Process(Record record) { for (int i=0; i<record.SubRecords.Count; ++i) { try { Validate(record.subRecords[i]); } catch (Exception ex) { var inner = new RecordValidationException(record, i, ex); _logger.Error( "Validation of subrecord {0} failed for record {1}", i, record ); } } } } There's a few important things to notice: A single error at the deepest level causes three log entries (ugly? DOS?) Thrown exceptions contain all important and useful information Logging only happens when failure to do so would cause loss of useful information at a lower level. Thoughts and concerns: I don't like having so many log entries for each error I don't want to lose important, useful data; the exceptions contain all the important but the stacktrace is typically the only thing displayed besides the message. I can log at different levels (e.g., warning, informational) The higher level classes should be completely unaware of the structure of the lower-level exceptions (which may change as the different implementations are replaced). The information available at higher levels should not be passed to the lower levels. So, to restate the main questions: What are best-practices for logging deep within an application's source? Is it bad practice to have multiple event log entries for a single error?

  • asp.net mvc xval validation

    - by mctayl
    Hi there I am using xval for the first time, it seems to work fine for required fields, However I am having some issues first of all it does not seem to validate booleans and also client validation is not working for me, this is not a major issue for me, the one that I really need to work is the stringlength property. It seems to do something because the form is not posted when the string length is exceeded, however no error message is displayed to the user which is obviously not what I want, has anyone been able to do this successfully? My model goes like this using System; using System.Collections.Generic; using System.Linq; using System.Web; using System.ComponentModel.DataAnnotations; namespace PitchPortal.Core { public class DocumentMetadata { //[Required] // public bool visibility { get; set; } [Required,StringLength(10, ErrorMessage = "title is too long")] public string title { get; set; } [Required, StringLength(10, ErrorMessage = "description is too long")] public string description { get; set; } [Required, StringLength(10, ErrorMessage = "summary is too long")] public string summary { get; set; } } } the html goes like this <div id="results" title="Upload results"/> <form id="myForm" action="<%=Url.Action("New") %>" method="post" enctype="multipart/form-data"> <% Html.EnableClientValidation(); %> <%= Html.ValidationSummary() %> <table> <tr> <td> <%=Html.Label("File")%></td> <td> <input type="file" id="file1" name="fileUpload" /> <br /> <%=Html.SubmitButton<DocumentController>(x => x.Upload(), "GetImage", "")%> </td> <td> <%=Html.ValidationMessage("file1")%> </td> </tr> <tr> <td> <%=Html.Label("Visible")%></td> <td> <%= Html.RadioButton( "visibility",true,true) %>true <%= Html.RadioButton("visibility", false)%>false </td> <td> <%= Html.ValidationMessage("visibility")%> </td> </tr> <tr> <td> <%=Html.Label("Title")%></td> <td> <%=Html.TextBox("doc.title")%></td> <td> <%= Html.ValidationMessage("doc.title")%></td> </tr> <tr> <td> <%=Html.Label("Description")%></td> <td><%= Html.TextArea("doc.description")%></td> <td><%= Html.ValidationMessage("doc.description")%></td> </tr> <tr> <td> <%=Html.Label("Summary")%></td> <td> <%= Html.TextArea("doc.summary")%></td> <td> <%= Html.ValidationMessage("doc.summary")%></td> </tr> <tr> <td> <%=Html.Label("Filetype")%></td> <td> <%= Html.DropDownList("Filetype_id", (IEnumerable<SelectListItem>)ViewData.Model.AllFiletypesList)%> </td> <td> <%= Html.ValidationMessage("doc.Filetype_id")%> </td> </tr> <tr> <td> <%=Html.Label("Category")%></td> <td><%= Html.DropDownList("cat.parent_id", (IEnumerable<SelectListItem>)ViewData.Model.AllCategoriesList, "-please select item-", new { className = "unselected" })%> </td> <td><%= Html.ValidationMessage("cat.parent_id")%> </td> </tr> <% if (Session["TempFolder"] == null) { for (int i = 1; i < 6; i++) { %> <tr> <td> <%=Html.Label("Shot "+i.ToString()) %> </td> <td><input type="file" id="image_<%= i.ToString() %>" name="image_<%= i.ToString() %>" /></td> </tr> <% } }%> <tr> <td><input type="submit" value="save"/></td> </tr> </table> </form> </div>

  • Validation for textfield is not working

    - by MaheshBabu
    Hi folks, I am using 4 Textfields in my application. I need to validate those textfields like,These 4 textfields Allow only o,1,....9 and . For that i use the code like this. - (BOOL)textField:(UITextField *)textField shouldChangeCharactersInRange:(NSRange)range replacementString:(NSString *)string { static NSCharacterSet *charSet = nil; if(!charSet) { charSet = [[[NSCharacterSet characterSetWithCharactersInString:@"0123456789."] invertedSet] retain]; } NSRange location = [string rangeOfCharacterFromSet:charSet]; return (location.location == NSNotFound); And first textfield allows digits 10,second third and fourth textfields allows less than 100. For that my code is if (textField.tag == 1) { NSString *newString = [textField.text stringByReplacingCharactersInRange:range withString:string]; double homevaluedouble = [newString doubleValue]; return !(homevaluedouble > 10000000000); } if (textField.tag == 2) { NSString *newString = [textField.text stringByReplacingCharactersInRange:range withString:string]; double validate = [newString doubleValue]; return !(validate > 100); } if (textField.tag == 3) { NSString *newString = [textField.text stringByReplacingCharactersInRange:range withString:string]; double validate = [newString doubleValue]; return !(validate > 100); } I write this code in - (BOOL)textField:(UITextField *)textField shouldChangeCharactersInRange:(NSRange)range replacementString:(NSString *)string { But textfields allows 0,1,..9 and . but digit limit is not working, if i remove 0,1,...9 then limit to textfield working. i am getting confuse with it. can any one pls help me,How can i resolve it.

  • php validation code format

    - by user2970887
    Okay I have this MySQL database form and am trying to add validation to it. After 2 days of fighting with it, I thought I would get some advice. Would like that the selected item from dropdown and Firstname, Phone, Email, are all required. Then I want to verify that the data in the Firstname, Lastname, Phone (doesn't have to be any special format), Email and Comments are all acceptable formats before putting in database.

    - by Noah McIlraith
    Under the application settings page in the Administration console, it is possible to specify a name for the application, AFAIK this is used in the login page when using the users API to login. I would like to be able to use this information within an application, currently, the title is also specified in a separate configuration file, but configuration repetition is something I would like to avoid if at all possible. Is there some way for a GAE application to determine the "Application Title"? Oh, also, I am using python.
