  • Sending and Receiving data through SOAP web service in .Net

    - by Nikhil Thaker
    I am working on a client - server application and in which I used to send and receive data through SOAP web service. Now after sometimes I have heard from someone that I might lost some data while this process on soap service created in ASP.net. So now I have decided to send and receive data through batches like first I will send List of 50 objects and then next 50 and so on... Now I am new to web services and all. So my question is "Is it true that we can lost some data sometimes while transferring it through SOAP web service?"

  • Using Javascript in Google Web Optimizer Page Sections

    - by Chris S
    Is it possible to use Javascript in the content of a page section variation? I want different variations to make different Javascript function calls, so I have variation content like: Variation 1 <script type="text/javascript">my_func('abc');</script> Variation 2 <script type="text/javascript">my_func('def');</script> However, when I preview my page, I can't verify that my_func(content){ alert(content); } is actually being run. Does GWO not support JS content, or am I missing something?

  • Rendering 'belongs_to" in index view question - Ruby on Rails

    - by bgadoci
    I have created a simple blog application with Ruby on Rails. The applications consists of two tables, posts and comments. Comments belongs_to :post and posts has_many :comments. I created posts table with the following columns: title:string, body:text. I created the comments table with the following columns: body:text post_id:integer name:string email:string In the /views/comments/index.html.erb display I would like to show a listing of all comments w/ the post title as well. Currently, the index view only displays post_id, body, name, email. How do I replace the post_id column with the corresponding post title? Here is my code: CommentsController Index action: def index @comments = Comment.all :order => "created_at DESC" respond_to do |format| format.html # index.html.erb format.xml { render :xml => @comments } format.json { render :json => @comments } format.atom end end /views/comments/index.html.erb <h1>Listing comments</h1> <table> <tr> <th>Post</th> <th>Body</th> </tr> <% @comments.each do |comment| %> <tr> <td><%=h comment.post_id %></td> <td><%=h comment.body %></td> <td><%=h comment.name %></td> <td><%=h comment.email %></td> </tr> <% end %> </table> <br />

  • Disabling Scrollbars in WebKit

    - by Aram Havarneanu
    Hello, I'm embedding WebKit in a Windows C++ Application. I'm using the Cairo port. It works fine. I'd like to disable the scrollbars that appear when there's more data that the client area can display. Like the iPhone, the iPhone does not have scrollbars, scrolling is implemented differently. How can I disable the scrollbars programatically, in C++ (no Javascript hacks)? Thanks,

  • Crawling within a pdf

    - by Saubhagya
    Hi, I'm developing a tool that searches the keyword entered by the user on a given site. My problem is, it searches the keyword only on html/web pages but not on the PDF/MS-Word files found on the site. Can anyone suggest me some api/tool or provide the code that can search text from the given online PDF/MS-Word/Text file?

  • How to restrict access to a class's data based on state?

    - by Marcus Swope
    In an ETL application I am working on, we have three basic processes: Validate and parse an XML file of customer information from a third party Match values received in the file to values in our system Load customer data in our system The issue here is that we may need to display the customer information from any or all of the above states to an internal user and there is data in our customer class that will never be populated before the values have been matched in our system (step 2). For this reason, I would like to have the values not even be available to be accessed when the customer is in this state, and I would like to have to avoid some repeated logic everywhere like: if (customer.IsMatched) DisplayTextOnWeb(customer.SomeMatchedValue); My first thought for this was to add a couple interfaces on top of Customer that would only expose the properties and behaviors of the current state, and then only deal with those interfaces. The problem with this approach is that there seems to be no good way to move from an ICustomerWithNoMatchedValues to an ICustomerWithMatchedValues without doing direct casts, etc... (or at least I can't find one). I can't be the first to have come across this, how do you normally approach this? As a last caveat, I would like for this solution to play nice with FluentNHibernate :) Thanks in advance...

  • Blank page shown in Mozilla Firefox

    - by Arun
    I have a jsf page which works perfectly fine[Both in IE and Mozilla Firefox] when the application is deployed locally. But i deploy it at the client place and I try to access the page in mozilla FF i get a blank page but it shows up properly in IE. Now if i do a remote desktop connection to the system where the application is deployed and try to access the same page i get to see the page correctly in both mozilla ff & IE Is this due to some sort of network issue specific to mozilla?

  • Flex: Would a computational engine for a Connect-4 type game be too slow?

    - by Robusto
    OK, I was just fooling around in my spare time and have made this cool interface and game-playing code for a Connect-4 type game, written in Flex and playable by 2 human players in Flash. It accurately detects wins, etc. I'm smart enough to know that I've done the easy part. Before I dig into an AI for game play, I wanted to ask if this is the kind of thing that can really be handled computationally by a Flash plugin. It seems to me that for every turn up until the end there are 8 possible moves, 8 responses to each move, etc. So wouldn't a perfect engine have to be able to potentially see 8^8 moves (over 16 million), and a fairly good engine see up to a million? I don't know game coding so this is new to me. What's a reasonable move horizon for such a game to be able to see?

  • Need help making row of buttons consistent

    - by oliverghingold
    I'm making my first website, and I'm trying to make variable-sized buttons so they'll render correctly on low resolution (read: mobile) browsers. Currently I just have the usual rollover image solution (185 pixels wide by 37 tall if anybody cares), but when I preview the site in low resolution it looks, predictably enough, like complete crap (more specifically they don't have room so they arrange vertically instead of horizontally and take up a huge amount of screen real estate). Semi-related, is there a way to overlay text on a button without saving separate images, each with the correct text? Just using a single template for buttons and then deciding what text goes on it as it's needed? tl;dr: I'm trying to get a horizontal lineup of buttons for navigating my website, but I'm a noob and I can't do it right without your generous assistance.

  • Horizontally align rows in multiple tables using web user control

    - by goku_da_master
    I need to align rows in different tables that are layed out horizontally. I'd prefer to put the html code in a single web user control so I can create as many instances of that control as I want and lay them out horizontally. The problem is, the text in the rows needs to wrap. So some rows may expand vertically and some may not (see the example below). When that happens, the rows in the other tables aren't aligned horizontally. I know I can accomplish all this by using a single table, but that would mean I'd have to duplicate the name, address and phone html code instead of dynamically creating new instances of my user control (in reality there are many more fields than this, but I'm keeping it simple). Is there any way to do this whether with div's, tables or something else? Here's the problem: Mary Jane's address field expands 2 lines, causing her phone field to not align properly with John's and Bob's. Name: John Doe Name: Mary Jane Name: Bob Smith Address: 123 broadway Address: Some really long address Address: Short address Phone: 123-456 that takes up multiple lines Phone: 111-2222 Phone: 456-789 I'm not restricted in any way how to do this (other than using asp.net), but I'd prefer to use a single web control that I instantiate X times at design time (in this example, it's 3 times). I'm using VS2008, and .Net 3.5

  • What kind of security issues will I have if I provide my web app write access?

    - by iama
    I would like to give my web application write access to a particular folder on my web server. My web app can create files on this folder and can write data to those files. However, the web app does not provide any interface to the users nor does it publicize the fact that it can create files or write to files. Am I susceptible to any security vulnerabilities? If so, what are they?

  • How can a large number of developers write software together without either a cumbersome process or

    - by Mark Robinson
    I work at a company with hundreds of people writing software for essentially the same product. The quality of the software has to be high because so many people depend on it (not least the developers themselves). Because of this every major issue has resulted in a new check - either automated or manual. As a result the process of delivering software is becoming ever more burdensome. So that requires more developers which... well you can see it is a vicious circle. We now have a problem with releasing software quickly - the lead time even to change one line of code for a very serious issue is at least one day. What techniques do you use to speed up the delivery of software in a large organization, while still maintaining software quality?

  • AJAX vs ActiveX/Flash for browser-based game

    - by iconiK
    I have been following the usage of JavaScript for the past few years, and with the release of extremely fast scripting engines (V8, SquirrelFish Extrene, TraceMonkey, etc.) the possibilities of JavaScript have increased dramatically. However, the usage share of Internet Explorer coupled with it's total lack of support for recent standards makes me want to drop a bomb on Microsoft's HQ, as it creates a huge amount of problems for any website. The game will need to be pretty dynamic client-side, with animations and other eye-candy things, but not a full-blown game like those that run directly in the OS using DirectX or OpenGL. However, this might be a little stretch for JavaScript and will certainly feel extremely slow in Internet Explorer (given that the current IE engine can be hundreds of times slower than SFX; gotta see what IE9 will bring), would it be better to just do the whole thing in Flash? I know this means requiring the plug-in AND I have no experience whatsoever with Flash (other than browsing YouTube :P). It also means I can't just output directly from PHP, I would have to use XML or some other format to pass data to it (JSON is directly integrated in JS and PHP can deal with it easily). Another idea would be to provide an alternative interface just for IE, though I don't know how (ActiveX maybe? or with Flash, then why not just provide it to all browsers) or totally not supporting it and requiring the use of other browsers, although this is plain stupid from a business perspective. So here am I, wondering what approach to take and thus asking for your advice. How should I build the client-side? AJAX in all browsers, Flash in all browsers or a mix (AJAX for "modern" browsers and something else for the "grandpa": IE).

  • Do Brainbench certifications carry any weight with employers?

    - by Joshua Carmody
    Back in 2000, I got a bunch of programming certifications from Brainbench. However, they didn't seem to be doing me any good, and they needed to be renewed every year, so I let them lapse. Recently I've been hearing more about Brainbench, and I've been wondering - do these certifications impress potential employers at all, in 2009? What has been your experience?

  • How to get all paths in drupal install

    - by Aaron
    Hi, I need to write a module that gives me a page will all possible paths in a drupal install, including orphaned pages. (site map won't work for that). I can query the url_alias table for aliases, and I can query the menu_router table for all paths, even ones set in page/feed displays in views. But, variable paths (those with arguments) get interpreted at run-time. So, is there a way to get all possible paths in a drupal install, including dynamic paths and orphans? It's catch22. I have to know all the urls ahead of time to get them.

  • How do I find Microsoft APIs?

    - by Stephen
    I'm a java programmer, and if I see something that: I don't know about or just want to find a method description without opening an ide or am on support I type java [classname] into google, and there it is. If I try this crazy stunt for C# I'll come up with a whole heap of tutorials (how do I use it etc). If I manage to get to MSDN, I have to wade through a page describing every .net technology to see how their syntax references the same object, and then I have to find the appropriate page from there ([class name] Constructor) for example. This is even more pronounced, because I don't have Visual Studio, so I've got nothing to make it easier. There must be something I'm missing or don't know... how does this situation work for Microsoft developers? how can I make my life easier/searches better? are there techniques that work no matter what computer I'm on (e.g. require no computer setup/downloads) Notes It could be thought that java is just "java", but it's just that the java apis are only referenced/defined in the core language. For all the other languages on the JVM, it's assumed that you will just learn the correct syntax to use the java apis. I presume that .Net only lists a whole heap of languages as the api classes are actually different and have different interfaces capabilities (or some approximation of this presumption). Edit While searching msdn works... in the java space I can type 'java [anyclass]' and it will generally be found... whether it's a java core api or a third party library

  • Please advise on handling the existing geek

    - by ranja
    Quick Story: I started a new job where everyone funneled their questions to 'the geek'. Being an experienced developer, I can do most of my assignments without consultation with the geek - thinks such as how to select the top 10 rows in a table. Question: Is there a preferred way of handling these cases without offending the existing geek while ensuring the best solution gets implemented? My issue is the the existing geek is very young and makes a lot of mistakes, but still sounds authoritative because the other coders are just out of school and don't know better.

  • Essential Programming Tools

    - by Mat
    We all have different needs due to the platform and/or stack we work with, and simple programmer preference is famous for starting religious wars. However, in each area there is usually a set of tools that get recommended over and over, even though people might individually prefer one member over the others. Unix text mode code editors, for example, is an extremely contentious issue but no one can deny that most people will choose either vi or emacs. So, without criticising the alternatives, recommend me developement tools. Text editors for different platforms, version control systems, bug trackers, database engines, templating systems... whatever! What do you enjoy using every day? I'll edit together the answers as a list of highly recommended tools in each area. Please don't start discussing which is the best ;)
