  • Configuration file reading. Best practice

    - by Andrew Florko
    Application stores configuration data in custom section of configuration file. This information is used all over the application. Nowadays I use helper static class to to provide access like this (some code omitted or simplified): [XmlRoot("webSiteSection")] public class WebSiteConfig : IConfigurationSectionHandler { public static WebSiteConfig Current { get { if (_current == null) _current = (WebSiteConfig) ConfigurationManager.GetSection("webSiteSection"); return _current; } } [XmlElement("section1")] public Section1 Section1 { get; set; } [XmlElement("section2")] public Section2 Section2 { get; set; } ... public object Create(object parent, object configContext, XmlNode section) { var serializer = new XmlSerializer(typeof(WebSiteConfig)); return serializer.Deserialize(new XmlNodeReader(section)); } } Then I use it like this <%: WebSiteConfig.Current.Section1.Value1 %> <%: WebSiteConfig.Current.Section1.Value2 %> What do you think of it? I find it usable because it keeps code simple, but also confused as IConfigurationSectionHandler is deprecated since .NET Framework 2.0

  • New to C# and trying to use a global variable

    - by Andrew G. Johnson
    Is it possible to use global variables in C#? I'm coming from mainly a PHP background so variables are either accessible everywhere or just a global definition away. My main issue is I have a User class that I built myself to wrap around the current users table on my company's database. I am defining it in the MasterPage but can't seem to access it from the actual pages (I don't know if there's a better word to describe them but they are the pages that inherit the styles and format from the MasterPage) Any general tips or implementation practices for me? EDIT: here's some code snippets of what I'm trying to do: Site.master.cs public partial class SiteMaster : System.Web.UI.MasterPage { public User user = new User(); } logout.aspx <%@ Page Title="" Language="C#" MasterPageFile="~/Site.master" AutoEventWireup="true" CodeFile="logout.aspx.cs" Inherits="logout" %> <%@ MasterType virtualPath="~/Site.master"%> logout.aspx.cs public partial class _Default : System.Web.UI.Page { protected void Page_Load(object sender, EventArgs e) { User user = Master.user; } }

  • MySQL GROUP_CONCAT + IN() = missing data :-(

    - by Andrew Heath
    Example: Table: box boxID color 01 red 02 blue 03 green Table: boxHas boxID has 01 apple 01 pear 01 grapes 01 banana 02 lime 02 apple 02 pear 03 chihuahua 03 nachos 03 baby crocodile I want to query on the contents of each box, and return a table with each ID, color, and a column that concatenates the contents of each box, so I use: SELECT box.boxID, box.color, GROUP_CONCAT(DISTINCT boxHas.has SEPARATOR ", ") AS contents FROM box LEFT JOIN boxHas ON box.boxID=boxHas.boxID WHERE boxHas.has IN ('apple','pear') GROUP BY box.boxID ORDER BY box.boxID and I get the following table of results: boxID color contents 01 red apple, pear 02 blue apple, pear My question to you is: why isn't it listing ALL the has values in the contents column? Why is my WHERE statement also cropping my GROUP_CONCAT? The table I thought I was going to get is: boxID color contents 01 red apple, banana, grapes, pear 02 blue apple, lime, pear Although I want to limit my boxID results based upon the WHERE statement, I do not want to limit the contents field for valid boxes. :-/ Help?

  • How to pass parameters to Apache Pivot's wtkx:include tag?

    - by Andrew Swan
    I need to create a reusable UI component that accepts a number of parameters (e.g. an image URL and some label text), similar to how JSP tags can accept parameters. The Pivot docs for the "wtkx:include" tag say: The tag allows a WTKX file to embed content defined in an external WTKX file as if it was defined in the source file itself. This is useful for ... defining reusable content templates I was hoping that I could define my component in a WTKX file using standard Pivot components (e.g. a TextInput) and pass it one or more parameters; for example my reusable template called "row.wtkx" might contain a row with an image and a text field, like this (where the ${xxx} bits are the parameters): <TablePane.Row xmlns="org.apache.pivot.wtk"> <ImageView image="@images/${image_url}" /> <TextInput text="${title}" /> </TablePane.Row> I could then reuse this component within a TablePane as follows: <rows> <TablePane.Row> <Label text="Painting"/> <Label text="Title"/> </TablePane.Row> <wtkx:include src="row.wtkx" image_url="mona_lisa.jpg" title="Mona Lisa"/> <wtkx:include src="row.wtkx" image_url="pearl_earring.jpg" title="Girl with a Pearl Earring"/> <wtkx:include src="row.wtkx" image_url="melting_clocks.jpg" title="Melting Clocks"/> </rows> I've made up the ${...} syntax myself just to show what I'm trying to do. Also, there could be other ways to pass the parameter values other than using attributes of the "wtkx:include" tag itself, e.g. pass a JSON-style map called say "args". The ability to pass parameters like this would make the include tag much more powerful, e.g. in my case allow me to eliminate a lot of duplication between the table row declarations. Or is "wtkx:include" not the right way to be doing this?

  • Test iPhone in-app purchases on a different bundle?

    - by Andrew Johnson
    We have a group of beta testers for iPhone app. Recently, we added in-app purchases to the app. Before this, we would send out ad hoc builds to beta testers using a separate bundle ID and name so that they could have the store build and the ad hoc build on their phones. However, it seems like we have to build the ad hoc copy with the same Bundle ID to test in-app purchases, and this means we can't send out a seperate beta copy - our beta file (annoyingly) overwrites the user's store-bought app. Is there any way to test in-app purchases in a different bundle ID? Do I need to set up fake, test in-app purchases for the test build too?

  • When to alter a function vs when to just write a new one...?

    - by Andrew Heath
    /is n00b Through the gift of knowledge and expertise encoded here, I am doing my best to avoid n00b mistakes as I learn the basics of programming. I use functions when I (think I) can in PHP, and keep them somewhat sorted in different includes. The n00b problem I'm running into now is situations where perhaps 4/5th of an existing function is relevant to a new need. Maybe there are a slightly different set of inputs, or an additional calculation or two in the series, or output needs a different format/structure... but the core of the function is still applicable. Is there a good rule of thumb regarding when one should bolt-on crap to an original function and when one should (literally) copy & paste most of it into a new function and tweak to fit the situation? On the one hand I feel bad duping code, on the other I feel bad cluttering up an existing function with stuff not always needed...

  • Django QuerySet ordering by expression

    - by Andrew
    How can i use order_by like order_by('field1'*'field2') For example i have items with price listed in different currencies, so to order items - i have to make currency conversion. class Currency(models.Model): code = models.CharField(max_length=3, primary_key=True) rateToUSD = models.DecimalField(max_digits=20,decimal_places=10) class Item(models.Model): priceRT = models.DecimalField(max_digits=15, decimal_places=2, default=0) cur = models.ForeignKey(Currency) I would like to have something like: Item.objects.all().order_by(F('priceRT')*F('cur__rateToUSD')) But unfortunately it doesnt work, i also faild with annotate. How can i permorm QuerySet ordering by result of value multiplication of 2 model's fields.

  • How to Inserting message into View that depends on session value. ASP.NET MVC. Best practice

    - by Andrew Florko
    User have to populate multistep questionnaire web-forms and step messages depend on the option chosen by user at the very beginning. Messages are stored in web.config file. I use asp.net mvc project, strong typed views and keep business logic separated from controller in static class. I don't want to make business logic dependency on web.config. Well, I have to insert message into view that depends on session value. There are at least 2 options how to implement this: View model has property that is populated in controller/businessLogic and rendered in view like <%: Model.HelpMessage1 %>. I have to pass web.config values from controller to businessLogic that makes business logic methods signature too complex. I don't want to make configuration source abstract (in order to let business logic read configuration values from its methods directly) also. Create static helper class that is called from view like <%: ViewHelper.HelpMessage1(Model.Option1) %>. But in this case logic what to show seems to be separated into two classes: business logic & viewHelper. What will you suggest? Thank you in advance!

  • Database Modelling - Conceptually different entities but with near identical fields

    - by Andrew Shepherd
    Suppose you have two sets of conceptual entities: MarketPriceDataSet which has multiple ForwardPriceEntries PoolPriceForecastDataSet which has multiple PoolPriceForecastEntry Both different child objects have near identical fields: ForwardPriceEntry has MarketPriceDataSetId (foreign key to parent table) StartDate EndDate SimulationItemId ForwardPrice PoolPriceForecastEntry has PoolPriceForecastDataSetId (foreign key to parent table) StartDate EndDate SimulationItemId ForecastPoolPrice If I modelled them as separate tables, the only difference would be the foreign key, and the name of the price field. There has been a debate as to whether the two near identical tables should be merged into one. Options I've thought of to model this is: Just keep them as two independent, separate tables Have both sets in the one table with an additional "type" field, and a parent_id equalling a foreign key to either parent table. This would sacrifice referential integrity checks. Have both sets in the one table with an additional "type" field, and create a complicated sequence of joining tables to maintain referential integrity. What do you think I should do, and why?

  • "conveyor belt" cache architecture

    - by Andrew Matthews
    I'm producing an application with a few peculiar internal communication characteristics that make the usual suspects for data storage and transport (Qs and RDBMSs) ill-fitted. I'm wondering whether there is a product out there that matches the following characteristics: all data put into it is peristent all reads are delivered out of memory data is universally available data lives where it is most needed data is versioned (nice to have) updates are transactional (I'd like ACID characteristics) data is potentially replicated, but always in sync works on windows is based on or has bindings for .NET is really fast is really robust is redundant is scalable I'm looking at things like Microsoft codename "Velocity", but I am not sure whether it fits all of the above characteristics. Likewise, Memcached is not a perfect fit either. The current version of this app opts for an RDBMS with a signaling system for inter-system sync, but latency is too high and versioning of the DB is a pain. I need all the robustness, but with none of the trade-offs.

  • NHibernate. DTO -> Domain

    - by Andrew Kalashnikov
    Hello guys. I've got SOA which processing data for diff clients(asp,sl). The base of this design is domains of my business model. For transporting,showing it to clients I use DTO. For mapping domain to DTO I use AutoMapper. Now I should persist new entities from clients. I want use my DTO's at this scenario too. So i've got some questions as I'm not much familiar with this design 1) Is it a good practice build DTO on client and send it to web-service on the wire? MayBe i should pass my domains? 2) Is it possible have several DTO's to one domain (one show at grid, and one to save). For saving I need set all nonprimitive props at client. 3) DTO - to Domain. If I've got int can I use AutoMapper to generate NHibernate Proxy for this ID, or I should do i manually. Your expierence and practice are very interesting. Thanks for answer!!!

  • Viewing Crystal Reports other than through custom developed webform or winform apps

    - by Andrew
    At work we currently have a custom in-house built winforms app for the business users to view reports. It has role-based security and several administrator functions. My boss is thinking about getting me to port this app to webforms. My question is, are there options other than custom built winforms and webforms apps for deploying/viewing/administrating Crystal Reports at an enterprise level (role-based security, easy report deployment, etc)? I'm thinking about third-party packages or perhaps applications provided by Microsoft/Business Objects/SAP? We are using Crystal Reports 11.5.

  • Finding spelling of an element in an ignore case dictionary

    - by Andrew White
    Hi, Weird question, but I have a dictionary created with StringComparer.OrdinalIgnoreCase, looks something like this AaA, 10 aAB, 20 AAC, 12 I then use myDictionary["AAA"] to find the value associated with the key, but what I also need to know is what the actual spelling of the key is in myDictionary, e.g. in this case I want it to return AaA. Any way to do this without a loop? Thx.

  • jQuery AJAX with two domains

    - by Andrew Burns
    OK here is the situation: I have an externally hosted CMS which works great for 99% of our needs. However on the more advanced things I inject my own CSS+JS and do magic. The problem I am running into is loading a simple HTML page from jQuery.ajax() calls. It appears to work in the sense that no warnings or errors are thrown; however in my success handler (which IS ran), the response is blank! I have been scratching my head for the whole morning trying to figure this out and the only thing I can think of is that is has something to do with the cross domain issue (even though it appears to work). Injected JavaScript: $(document).ready(function() { doui(); }); function doui() { $.ajax({ url: 'http://apps.natronacounty-wy.gov/css/feecalc/ui.htm', cache: false, success: ajax_createUI, charset: "utf-8", error: function(e) { alert(e); } }); } function ajax_createUI(data, textStatus) { alert(data); $("#ajax-content").html(data); } My ajax_createUI() success handler is called and textStatus is "success"; however data is empty. This JS file resides @ http://apps.natronacounty-wy.gov/css/js/feecalc.js however the CMS website (which gets the JS injected into it) resides @ http://www.natronacounty-wy.gov/ Am I just being stupid or is it a bug that it looks like it should be working but isn't?

  • Using unmanaged code, how can I find a type that has a given custom attribute assigned to it?

    - by Andrew
    I had thought I could enumerate the types using IMetaDataImport.EnumTypeDefs and for each of the tokens returned, call IMetaDataImport.EnumCustomAttributes. This works, in so much as I get an array of mdCustomAttribute tokens. Using these tokens I can get a metadata token representing the Type of the returned custom attribute, by calling IMetaDataImport.GetCustomAttributeProps. Comparing my results against ILDASM, I can see that this matches the "CustomAttribute Type" that ILDASM reports. However, I cannot work out how to determine the "CustomAttributeName" that ILDASM reports. This is what I really want! While I would be interested in knowing how to get the CustomAttributeName, I would settle for an alternate approach to solving the problem.

  • Creating a [materialised]view from generic data in Oracle/Mysql

    - by Andrew White
    I have a generic datamodel with 3 tables CREATE TABLE Properties ( propertyId int(11) NOT NULL AUTO_INCREMENT, name varchar(80) NOT NULL ) CREATE TABLE Customers ( customerId int(11) NOT NULL AUTO_INCREMENT, customerName varchar(80) NOT NULL ) CREATE TABLE PropertyValues ( propertyId int(11) NOT NULL, customerId int(11) NOT NULL, value varchar(80) NOT NULL ) INSERT INTO Properties VALUES (1, 'Age'); INSERT INTO Properties VALUES (2, 'Weight'); INSERT INTO Customers VALUES (1, 'Bob'); INSERT INTO Customers VALUES (2, 'Tom'); INSERT INTO PropertyValues VALUES (1, 1, '34'); INSERT INTO PropertyValues VALUES (2, 1, '80KG'); INSERT INTO PropertyValues VALUES (1, 2, '24'); INSERT INTO PropertyValues VALUES (2, 2, '53KG'); What I would like to do is create a view that has as columns all the ROWS in Properties and has as rows the entries in Customers. The column values are populated from PropertyValues. e.g. customerId Age Weight 1 34 80KG 2 24 53KG I'm thinking I need a stored procedure to do this and perhaps a materialised view (the entries in the table "Properties" change rarely). Any tips?

  • php error reporting - having trouble matching local & web server settings

    - by Andrew Heath
    I'm trying to add a custom error handler to my site, but in doing so have discovered that my webhost's PHP error reporting settings and those of my localhost (default XAMPP) vary considerably. While I thought I was programming to E_STRICT like a good little boy, adding the error handler to my webhost revealed craploads of Runtime Notices. Example: Runtime notice strtotime() [function.strtotime]: It is not safe to rely on the system's timezone settings. Please use the date.timezone setting, the TZ environment variable or the date_default_timezone_set() function. In case you used any of those methods and you are still getting this warning, you most likely misspelled the timezone identifier. We selected 'America/Chicago' for 'CST/-6.0/no DST' instead In /home/... Clearly this isn't a red-alert, showstopping error. But what bothers me is that it doesn't show up on my localhost. I'd certainly like to improve my code by addressing these sorts of issues if I could see them! I've looked through both php.ini files, and my webhost's setting is error_reporting = E_ALL & ~E_NOTICE whereas mine was error_reporting = E_STRICT, which I had thought was better. However, changing mine to match and rebooting the server doesn't seem to have accomplished anything. Could someone please point me in the right direction?

  • Android depth buffer issue: Advice for anyone experiencing problem

    - by Andrew Smith
    I've wasted around 30 hours this week writing and re-writing code, believing that I had misunderstood how the OpenGL depth buffer works. Everything I tried, failed. I have now resolved my problem by finding what may be an error in the Android implementation of OpenGL. See this API entry: http://www.opengl.org/sdk/docs/man/xhtml/glClearDepth.xml void glClearDepth(GLclampd depth); Specifies the depth value used when the depth buffer is cleared. The initial value is 1. Android's implementation has two versions of this command: glClearDepthx which takes an integer value, clamped 0-1 glClearDepthf which takes a floating point value, clamped 0-1 If you use glClearDepthf(1) then you get the results you would expect. If you use glClearDepthx(1), as I was doing then you get different results. (Note that 1 is the default value, but calling the command with the argument 1 produces different results than not calling it at all.) Quite what is happening I do not know, but the depth buffer was being cleared to a value different from what I had specified.
