• Smallcaps / multiple fonts and bolding using 'DrawString' in GDI+

  - by Simon_Weaver

  I want to write out some text using smallcaps in combination with different fonts for different words. To clarify I might want the message 'Welcome to our New Website' which is generated into a PNG file for the header of a page. The text will be smallcaps - everything is capitalized but the 'W', 'N' and 'W' are slightly larger. The 'New Website' will be in a different font than the rest of the text. Is there a way i can do this without doing it completely manually? Doing something like this is conceptually what I want to do : graphics.DrawString("<font size=2>W</font>ELCOME TO OUR <b><font size=2>N</font>" + "EW <font size=2>W</font>EBSITE</b>"); The best approach I could find so far is here, but I'm worried that I'll go to all the trouble to do this manually and end up with some horrible kerning or tracking problems. Edit: I should have mentioned that this is being done within ASP.NET so it needs to be fast and as lean as possible. I want it to be automated so I can localize easily and not have to create tonnes of little images.

• How to Implement Dynamic Timestamp in Web Page?

  - by Morgan Cheng

  In Facebook and twitter, we can see that there is a timestamp like "23 seconds ago" or "1 hour ago" for each event & tweet. If we leave the page for some time, the timestamp changes accordingly. Since it is possible that user machine doesn't have same system time as server machine, how to make the dynamic timestamp accurate? My idea is: It is always based on server time. When request is sent to server for the web page, timestamp T1 (seconds to 1970/1/1) is rendered into inline javascript variable. The displayed timestamp ("23 seconds ago") is calculated by T1 instead of local time. I'm not sure whether this is how Facebook/Twitter do it. Is there any better idea?

• Security when writing a PHP webservice?

  - by chustar

  I am writing a web service in PHP for the first time and had ran into some security problems. 1) I am planning to hash passwords using md5() before I write them to the database (or to authenticate the user) but I realize that to do that, I would have to transmit the password in plaintext to the server and hash it there. Because of this I thought of md5()ing it with javascript client side and then rehashing on the server but then if javascript is disabled, then the user can't login, right? 2) I have heard that anything that when the action is readonly, you should use GET but if it modifies the database, you should use POST. Isn't post just as transparent as GET, just not in the address bar?

• Searching for the right pattern to handle login data

  - by stevebot

  Hi all, I'm working on a controller that handles logins for a Web app. These logins will come from multiple clients but will all contain the same data. However, depending on the client, this data will be interpreted into common entities for our webapp differently. For instance, we have a user code that gets sent in, and in one case we may use the first four digits of the code, and in another case 12 digits of the code to map to a field on a User entity. Instead of handling this all in the controller and having big nasty if blocks of logic, I would like to use a pattern to handle how this information gets ingested into our application. What are your opinions?

• Using Linq on a Dataset

  - by JasonMHirst

  Can someone enlighthen me with regards to Linq please? I have a dataset that is populated via a SQL Stored Procedure, the format of which is below: Country | Brand | Variant | 2004 | 2005 | 2006 | 2007 | 2008 The number of rows varies between 50 and several thousand. What I'm trying to do is use Linq to interrogate the dataset (there will be several Linq queries based on user options), but a simple example would be to SUM the year columns based on Brand. I have the following that I believe creates a template for me to work with: But from here on I'm absolutely stuck! sqlDA.Fill(ds, "Profiler") Dim brandsQuery = From cust In ds.Tables(0).AsEnumerable() Select _BrandName = cust.Item("BrandName"), _y0 = cust.Item("1999"), _y1 = cust.Item("2004"), _y2 = cust.Item("2005"), _y3 = cust.Item("2006"), _y4 = cust.Item("2007"), _y5 = cust.Item("2008") I'm tried to look at examples, but can't see any that are VB.Net based and/or show me how to Sum/Group. Can someone please provide an example so I can perhaps learn from it. Thanks.

• What are the common patterns in web programming?

  - by lankerisms

  I have been trying to write my first big web app (more than one cgi file) and as I kept moving forward with the rough prototype, paralelly trying to predict more tasks, this is the todo that got accumulated (In no particular order). * Validations and input sanitizations * Object versioning (to avoid edit conflicts. I dont want hard locks) * Exception handling * memcache * xss and injection protections * javascript * html * ACLs * phonetics in search, match and find duplicates (for form validation) * Ajaxify!!! (I have snipped off the project specific items.) I know that each todo will be quite tied up to its project and technologies used. What I am wondering though, is if there is a pattern in your todo items as well as the sequence in which you experienced guys have come across them.

• Single-Page Web Apps: Client-side datastores & server persistence

  - by fig-gnuton

  How should client-side datastores & persistence be handled in a single-page web application? Global vars vs. DI/IoC: Should datastores be assigned to global variables so any part of the application can access them? Or should they be dependency injected where required? Server persistence: Assuming a datastore's data needn't always be persisted to the server immediately, should the datastore itself handle persistence? If not, then what class should handle persistence and how should the persistence class fit into the client-side architecture overall? Is the datastore considered the model in MVC, or is it something else since it just stores raw data?

• Django: Proper place to unregister ModelAdmins

  - by lazerscience

  Sometimes I need to UNREGISTER some ModelAdmins from the admin site, because I don't want them to be there as they are, eg. if I'm using the Sites framework, and I dont want it to appear in the admin. It's no big deal to e.g. call admin.site.unregister(Site) to do so. In most cases I put it in admin.py of some related app that I have made, but sometimes I end up putting it in a place that hasn't much to do with the original app; another possibility would be making a "dummy app" and put it there... Does anybody know a more descent place where these calls can live?

• Advice needed for a small web application's architecture/implementation

  - by Johhny P

  I was asked to build a website where a company's employees (around 20) could login and fill in their working schedules for a present and past (if needed) month. Employees should ofcourse only be able to see their own schedules, but the manager should have the privilege to access every schedule. I have little experience in web development therefore an advice is needed. I have already created a PHP/MySql login page. Now what? How do I go about it? Just some architectural or implementational(if you will) guidance would be really appreciated.

• Beginner Design pattern question (Web Services involved)

  - by zombie

  Hi all ! I am a noob to web services world. I need to develop a login validator module and expose it as a service. I want it to be service independent, i.e I should have the option of exposing it as a SOAP service or REST service in the future. What pattern should I follow ? Sorry if I am unclear in my requirements, I can clarify as per need. Thanks !! Edit : I am using Eclipse as an IDE and Jersey libraries. I am not into any framework, simply using the MVC pattern. I find a lot of difference between SOAP ann REST methods, so I want my methods to be implementation independent - i.e I should be easily able to use my method through a SOAP or REST service call as per need. What should I do for maximum flexibility ?

• One account, multiple users, multiple shopping cart in a web application

  - by lemotdit

  I received a somewhat unusual request (imo) for a transactional web site. I have to implement the possibility of having multiple shopping cart for the same user. Those really are shopping carts, not order templates. I.E: A store with several departments ordering under the same account, but with a different person placing orders for a specific department only. Having more than one user per account is not an option since it would involve 'too much' management from the stores owner and the admins. Anyone had to deal with this before? The option so far is to have names for shopping cart, and a dropdown list or something alike after login to choose the cart with some kind of 'busy flag' to lock the cart if it's in use in another session.

All answers really appreciated, Thanks a lot --MB

• is it possible to use a python scrapper in a website?

  - by Tom

  I want to scrap a website and use that content in a website of my own. I am just wondering if that can be done with python 2.7, and if so how? If not, do I have to use JavaScript to scrap it? And do you have a good place to learn how to do that or good libraries for it. For those of you wondering, the website I am scrapping is legal, and they allow for this to be done. I have searched all over but apparently nobody tries to implement these scrappers that they write. I can write a web scrapper in python just fine. Say my scrapper scraps a name from a wikipedia page (John Doe for example), how can I use that name that I get in my website? Another update, I have found pjsrape and PhantomJS. I have only found one stack overflow post and the github examples with aren't very intuitive. If anybody has any experience or better ways to do it I would very much appreciate it

• Using Lambda Statements for Event Handlers

  - by lush

  I currently have a page which is declared as follows: public partial class MyPage : System.Web.UI.Page { protected void Page_Load(object sender, EventArgs e) { //snip MyButton.Click += (o, i) => { //snip } } } I've only recently moved to .NET 3.5 from 1.1, so I'm used to writing event handlers outside of the Page_Load. My question is; are there any performance drawbacks or pitfalls I should watch out for when using the lambda method for this? I prefer it, as it's certainly more concise, but I do not want to sacrifice performance to use it. Thanks.

• DXperience v2010 vol 2 Review

  - by kulrom

  Hi guys, this is my second review of these controls, and it will be quite different than the first. A few months ago I was engaged by a client to develop a web based application. He asked me (I guess they all ask the same) to make it good looking and attractive. The first thing I thought of when I heard this was "I must renew my DXperience subscription". And now I am glad I did that. Before I continue, I would like to say something to those readers who are totally new to DXperience. Guys, we all know that one of the more frustrating things for the ASP.NET developers is designing the good looking application. Well folks, your troubles are over! The DXperience takes much of the agony out of developing and designing an outstanding web application. Here we go!...(read more)

• Single Sign On with 3 applications

  - by John H.

  I'm building three web applications in .NET that will all share a users database and login information. Lets pretend that application 1 is the "parent" application and applications "A" and "B" are the "child" applications. All users have to be logged into application 1 to have access to applications A and B. Authorization, Authentication, and MachineKey sections of all web configs are present and work correctly. I have the correct web.config settings in all applications to achieve Single Sign On except one problem remains: what do I put in the "loginUrl" attribute of the forms tag in Applications A and B. Assume that the url for the login to application 1 is "www.johnsapp.com/login.aspx" How can I get applications A and B to send the user back to application 1 for authentication using only settings in web.config?

• Java technologies for web-development.

  - by Alex

  Hello. I'm PHP-programmer, but I'm extremely interested in learning Java. So I decided to change speciality from PHP to Java. At the moment I have an opportunity to try to make quite simple web-application (it should contain 2-3 forms, several pages with information from the database and authorization module) and also I have a chance to choose any technology I want. Besides I have about 3 months for this task. I've decided to develop site with Java technologies for the purpose of studying. I've already read a book about Java ("Java2 Complete Reference" by P.Naughton) and currently I'm reading "Thinking in Java" by B.Eckel. I clearly understand it's not enough for efficient development, but I want, at least, to try. I would be very appreciated for the advises, which framework (for example) or technology to choose (Spring, Grails etc.) and what primary aspects and technologies of Java should I pay attention to? Thank you in advance.

• The underlying connection was closed when using a WSDL web service

  - by joshlrogers

  I am trying to consume this WSDL service: Transit Time Service I successfully connect and get a response the first time but on subsequent calls I receive the exception: The underlying connection was closed: A connection that was expected to be kept alive was closed by the server. I overrode the GetWebRequest in the reference.cs file as such: protected override System.Net.WebRequest GetWebRequest(Uri uri) { HttpWebRequest webRequest = (HttpWebRequest)base.GetWebRequest(uri); webRequest.KeepAlive = false; return webRequest; } This hasn't yielded any improvement. I am at a loss as to what options I have now, does anyone have any other ideas that I could try so that I may avoid this error? Thanks in advance! Josh

• Does MVC replace traditional manually created BLL?

  - by used2could

  I'm used to creating the UI, BLL, DAL by hand (some times I've used LINQ-to-SQL or SubSonic for the DAL). I've done several small projects using MVC since its release. On these projects I've still continued to write a BLL and DAL by hand and then incorporate those into the MVC's models/controllers. I'm looking to optimize my time on projects this seems like overkill and a potential waste of time. Question Would it be acceptable to roll a DAL such as SubSonic and directly use it in the Models/Controllers of my MVC web app? Now the models & controllers would act as the BLL. I just see this as a major timesaver to not have to worry about another tier. UPDATE: I just wanted to add that my concern isn't really with the DAL (I frequently use SubSonic and NH) but rather focus on the BLL. Sorry for the confusion.

• Free service that allows storing game data online?

  - by StackedCrooked

  I have created a small game in Java and I would like to add the ability for a player to publish his highscores online. I'm willing to write the server software myself (it's easy these days with Ruby Mongrel, or even C++). All I just need to have some sort hosting. One solution that immediately comes to mind is Amazon EC2. But that's kind of expensive for my needs. Since the requirements are very minimal (I don't even need a website, just a web service) I think there may be a cheaper solution out there. Does anyone know of a free or cheap provider for this kind of thing?
