  • Generating HTML Programmatically in C#, Targeting Printed Reports

    - by John Passaniti
    I've taken over a C# (2.0) code base that has the ability to print information. The code to do this is insanely tedious. Elements are drawn onto each page, with magic constants representing positioning. I imagine the programmer sitting with a ruler, designing each page by measuring and typing in the positions. And yes, one could certainly come up with some nice abstractions to make this approach rational. But I am looking at a different method. The idea is that I'll replace the current code that prints with code that generates static HTML pages, saves them to a file, and then launches the web browser on that file. The most obvious benefit is that I don't have to deal with formatting-- I can let the web browser do that for me with tags and CSS. So what I am looking for is a very lightweight set of classes that I can use to help generate HTML. I don't need anything as heavyweight as HTMLTextWriter. What I'm looking for is something to avoid fragments like this: String.Format("<tr><td>{0}</td><td>{1}</td></tr>", foo, bar); And instead take have this kind of feel: ... table(). tr(). td(foo). td(bar) Or something like that. I've seen lightweight classes like that for other languages but can't find the equivalent (or better) for C#. I can certainly write it myself, but I'm a firm believer in not reinventing wheels. Know anything like this? Know anything better than this?

  • R: How to write out a data.frame so that I can paste it into SO for others to read?

    - by John
    I have a large data.frame displaying some weird properties when plotted. I'd like to ask a question about it on Stackoverflow, to do that I'd like to write the data.frame out in a form that I can paste it into SO and somebody else can easily run it and have it back into a data.frame object again. Is there an easy way to accomplish this? Also, if it is really long, should I use paste bin instead of directly paste it here?

  • Rails 3 MySQL 2 reports an error in what looks to be valid SQL syntax

    - by John Judd
    I am trying to use the following bit of code to help in seeding my database. I need to add data continually over development and do not want to have to completely reseed data every time I add something new to the seeds.rb file. So I added the following function to insert the data if it doesn't already exist. def AddSetting(group, name, value, desc) Admin::Setting.create({group: group, name: name, value: value, description: desc}) unless Admin::Setting.find_by_sql("SELECT * FROM admin_settings WHERE group = '#{group}' AND name = '#{name}';").exists? end AddSetting('google', 'analytics_id', '', 'The ID of your Google Analytics account.') AddSetting('general', 'page_title', '', '') AddSetting('general', 'tag_line', '', '') This function is included in the db/seeds.rb file. Is this the right way to do this? However I am getting the following error when I try to run it through rake. rake aborted! Mysql2::Error: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'group = 'google' AND name = 'analytics_id'' at line 1: SELECT * FROM admin_settings WHERE group = 'google' AND name = 'analytics_id'; Tasks: TOP => db:seed (See full trace by running task with --trace) Process finished with exit code 1 What is confusing me is that I am generating correct SQL as far as I can tell. In fact my code generates the SQL and I pass that to the find_by_sql function for the model, Rails itself can't be changing the SQL, or is it? SELECT * FROM admin_settings WHERE group = 'google' AND name = 'analytics_id'; I've written a lot of SQL over the years and I've looked through similar questions here. Maybe I've missed something, but I cannot see it.

  • Does Flash Builder 4 now use AIR 2?

    - by John Isaacks
    I just got CS5 master suite which includes Flash Builder 4 and Flash CS5 Pro. When I create a new AIR app in CS5 pro it says "AIR 2" but when I create a new AIR project in Flash Builder I do not see anything indicating that it is AIR 2 or 1.5? Is there a way to tell which AIR runtime it is using?

  • Does HTML5 only replace the video aspects of Flash/Silverlight?

    - by John
    I see a lot of talk how HTML5 video tag will kill Flash. But while video is the most widely used part of Flash/SL, it's only a small part of their technical abilities. For instance you can write a game using full 3D graphics and socket connections in Flex, and serious business applications, etc. Is the thinking that Javascript will kill those parts of Flash/Flex/SL? Because while that seems feasible now for even quite rich web-apps, what about any kind of high-performance app like real-time graphics?

Thanks

  • How to test that invalid arguments raise an ArgumentError exception using RSpec?

    - by John Topley
    I'm writing a RubyGem that can raise an ArgumentError if the arguments supplied to its single method are invalid. How can I write a test for this using RSpec? The example below shows the sort of implementation I have in mind. The bar method expects a single boolean argument (:baz), the type of which is checked to make sure that it actually is a boolean: module Foo def self.bar(options = {}) baz = options.fetch(:baz, true) validate_arguments(baz) end def self.validate_arguments(baz) raise(ArgumentError, ":baz must be a boolean") unless valid_baz?(baz) end def self.valid_baz?(baz) baz.is_a?(TrueClass) || baz.is_a?(FalseClass) end end

  • Does a Distributed Version Control System really have no centralised repository?

    - by John
    It might seem a silly question, but how do you get a working drectory set up without a server to check out from? And how does a business keep a safe backed up copy of the repo? I assume then there must be a central repo... but then how exactly is it 'distributed'? I always thought of a server-client (SVN) Vs peer-2-peer (GIT) distinction, but I don't believe that can be correct unless tools like GIT are dependent on torrent-style technology?

  • Is OpenID too complicated?

    - by John Leidegren
    I'm beginning to seriously doubt the OpenID community despite that fact that it works. I'm in the process of currently evaluating OpenID as an authentication service for 'this' site and while the promises are great, I just can't get it to work. And I'm really lost. I ask of the SO community to help me out here. Give me answers and show me examples so I can leverage this in the way it was meant to be. My scenario is very typical. I want to authenticate users through a specific Google Apps domain. If you have access to this Google Apps domain, then you have access to my web application. Where I get lost, is all the prerequisites and dependencies involved. What is XRD? What is Yadis? Why do I need XRD and Yadis? What do I need to do to deploy OpenID authentication on my website? Also, this is really important to me. When I login to SO, I use my Google Account. When I click the login button I'm presented with this confirmation page. Where I'm granting SO the right to use my Google Account credentials. Somehow, Google knows that it's "Stackoverflow.com" that's asking me if it's okay to login. And I wish to know what manner of control I have over this little text. I intend to deploy OpenID on several different domains but I would prefer if they would all work without having to be individually configured with special parameters, such as secret API keys and what not. However, I don't know for sure if this is a prerequisite of OpenID, that or the Federated Login API that Google provides.

  • C++: use array of strings wrapped in namespace?

    - by John D.
    I got the following code, wishing to wrap a group of strings nicely in a namespace: namespace msgs { const int arr_sz = 3; const char *msg[arr_sz] = {"blank", "blank", "blank" }; msg[0] = "Welcome, lets start by getting a little info from you!\n"; msg[1] = "Alright, bla bla bla.."; msg[2] = "etc."; } The code inside works nicely inside a function, but I don't know how to return an array from it. The namespace idea LOOKS fine, but it returns on the last three lines: error: expected constructor, destructor, or type conversion before ‘=’ token Why can't I define the array inside a namespace, do I need to do something first? It's nice because I can call it like printf(msgs::msg[1]) etc. I want to do this I just can't wrap my head around what's wrong :(

  • iPhone: InterfaceBuilder nibs disconnected from my project

    - by John Leonard
    Since upgrading to XCode 3.2, InterfaceBuilder doesn't play nice. All of my image links are broken in IB but they'll show fine when I compile. When I go to the combo box to select an image for my UIImageView, it doesn't have the image files I've added to my app. I also can't create a new .nib and associate it with a class I've written. Like images, my custom viewcontrollers aren't available to pick from. I'm going to try a reinstall but I was curious if anyone's dealt with this?

  • Javascript append to onClick event

    - by John Hartsock
    Guys I have the following Code which I know doesnt work correctly. Yes I know how to do this in JQuery but In this case I cannot use jquery. Please no jquery answers. <form> <input type="text" name="input1" onclick="alert('hello')"> <input type="text" name="input2"> <input type="text" name="input3"> </form> <script type="text\javascript"> window.onload = function () { var currentOnClick; for (var i = 0; i < document.forms[0].elements.length; i++) { currentOnClick = document.forms[0].elements[i].onclick; document.forms[0].elements[i].onclick = function () { if (currentOnClick) { currentOnClick(); } alert("hello2"); } } } </script> What Im trying to do is iterate through the form's elements and add to the onclick function. But due to the fact that in my last iteration currentOnClick is null this does not run as expected. I want to preserve each of the elements onclick methods and play them back in the new fuction Im creating. What I want: When input1 is clicked, alert "hello" then alert "hello2" When Input2 is clicked, alert "hello2" When Input3 is clicked, alert "hello2"

  • JMS message. Model to include data or pointers to data?

    - by John
    I am trying to resolve a design difference of opinion where neither of us has experience with JMS. We want to use JMS to communicate between a j2ee application and the stand-alone application when a new event occurs. We would be using a single point-to-point queue. Both sides are Java-based. The question is whether to send the event data itself in the JMS message body or to send a pointer to the data so that the stand-alone program can retrieve it. Details below. I have a j2ee application that supports data entry of new and updated persons and related events. The person records and associated events are written to an Oracle database. There are also stand-alone, separate programs that contribute new person and event records to the database. When a new event occurs through any of 5-10 different application functions, I need to notify remote systems through an outbound interface using an industry-specific standard messaging protocol. The outbound interface has been designed as a stand-alone application to support scalability through asynchronous operation and by moving it to a separate server. The j2ee application currently has most of the data in memory at the time the event is entered. The data would consist of approximately 6 different objects; a person object and some with multiple instances for an average size in the range of 3000 to 20,000 bytes. Some special cases could be many times this amount. From a performance and reliability perspective, should I model the JMS message to pass all the data needed to create the interface message, or model the JMS message to contain record keys for the data and have the stand-alone Java application retrieve the data to create the interface message?

  • How to run a command on a remote Windows system as a non-admin user with WMI?

    - by John
    I have a script written in Visual Basic that starts a process (given to the script as an argument) on a remote system (again, given as an argument) using WMI. This script works fine when using an Administrator account on the remote system, but when using a non-administrator account, I get the following error: ConnectServer Failed w/ (-2147024891) Access is denied. I'd like to be able to run processes on remote systems as a non-administrator user with this script, and I'm pretty sure the problem is due to security settings on the remote system, but I've not been able to reset the right ones.

  • Comma separated values in a database field

    - by John Doe
    I have a products table. Each row in that table corresponds to a single product and it's identified by a unique Id. Now each product can have multiple "codes" associated with that product. For example: Id | Code ---------------------- 0001 | IN,ON,ME,OH 0002 | ON,VI,AC,ZO 0003 | QA,PS,OO,ME What I'm trying to do is create a stored procedure so that I can pass in a codes like "ON,ME" and have it return every product that contains the "ON" or "ME" code. Since the codes are comma separated, I don't know how I can split those and search them. Is this possible using only TSQL? Edit: It's a mission critical table. I don't have the authority to change it.

  • Is a web-server (e.g servlets) a good solution for an IM server?

    - by John
    I'm looking at a new app, broadly speaking an IM application with a strong client-server model - all communications go through a server so they can be logged centrally. The server will be Java in some form, clients could at this point be anything from a .NET Desktop app to Flex/Silverlight, to a simple web-interface using JS/AJAX. I had anticipated doing the server using standard J2EE so I get a thread-safe, multi-user server for 'free'... to make things simple let's say using Servlets (but in practice SpringMVC would be likely). This all seemed very neat but I'm concerned if the stateless nature of Servlets is the best approach. If my memory of servlets (been a year or two) is right, each time a client sent a HTTP request, typically a new message entered by the user, the servlet could not assume it had the user/chat in memory and might have to get it from the DB... regardless it has to look it up. Then it either has to use some PUSH system to inform other members of the chat, or cache that there are new messages, for other clients who poll the server using AJAX or similar - and when they poll it again has to lookup the chat, including new messages, and send the new data. I'm wondering if a better system would be the server is running core Java, and implements a socket-based communication with clients. This allows much more immediate data transfer and is more flexible if say the IM client included some game you could play. But then you're writing a custom server and sockets don't sound very friendly to a browser-based client on current browsers. Am I missing some big piece of the puzzle here, it kind of feels like I am? Perhaps a better way to ask the question would simply be "if the client was browser-based using HTML/JS and had to run on IE7+,FF2+ (i.e no HTML5), how would you implement the server?" edit: if you are going to suggest using XMPP, I have been trying to get my head around this in another question, so please consider if that's a more appropriate place to discuss this specifically.

  • How to update MySQL table with a cumulative count of events with the same date

    - by John
    I have a table which I pull data from. This data has a date and a stock symbol. There can be multiple rows of data with the same date and different stock symbols. I need to update the table so that there is a running total for all rows with the same date. When a new date occurs the cumulative count re-sets to 1 and then resumes. A typical query: mysql> SELECT Sym 'sym' , fdate as 'FilledDate', TsTradeNum 'numT' -> FROM trades_entered_b2 -> WHERE fDate >= '2009-08-03' AND fDate <= '2009-08-07' -> LIMIT 10; +------+------------+------+ | sym | FilledDate | numT | +------+------------+------+ | WAT | 2009-08-03 | 0 | | ALGN | 2009-08-04 | 0 | | POT | 2009-08-05 | 0 | | PTR | 2009-08-06 | 0 | | SCHW | 2009-08-06 | 0 | | FDO | 2009-08-07 | 0 | | NBL | 2009-08-07 | 0 | | RRC | 2009-08-07 | 0 | | WAT | 2009-08-08 | 0 | | COCO | 2009-08-08 | 0 | +------+------------+------+ What I want: +------+------------+------+ | sym | FilledDate | numT | +------+------------+------+ | WAT | 2009-08-03 | 1 | | ALGN | 2009-08-04 | 1 | | POT | 2009-08-05 | 1 | | PTR | 2009-08-06 | 1 | | SCHW | 2009-08-06 | 2 | | FDO | 2009-08-07 | 3 | | NBL | 2009-08-07 | 4 | | RRC | 2009-08-07 | 5 | | WAT | 2009-08-08 | 1 | | COCO | 2009-08-08 | 2 | +------+------------+------+ What I need to do is update the TsTradeNum column with the correct values. I have tried to create a function and various queries all failed. Any ideas? Thanks in advance

  • XHTML 1.0 DocType ignored in all browsers?

    - by John
    I was testing this, since I understood using XHTML let me use any valid XML for empty <div> elements: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"> <html> <head> <meta http-equiv="Content-Type" content="text/html;charset=utf-8"> <title>Test</title> </head> <body> <div style="border:solid 10px black; width:100px; height:100px"></div> <div style="border:solid 10px red; width:100px; height:100px"></div> <div style="border:solid 10px blue; width:100px; height:100px"></div> <div style="border:solid 10px black; width:100px; height:100px" /> <div style="border:solid 10px red; width:100px; height:100px" /> <div style="border:solid 10px blue; width:100px; height:100px" /> </body> </html> It doesn't work in any browser I try... this is how FireBug tells me it understands the document: <html> <head> <meta content="text/html;charset=utf-8" http-equiv="Content-Type"/> <title>Test</title> </head> <body> <div style="border: 10px solid black; width: 100px; height: 100px;"/> <div style="border: 10px solid red; width: 100px; height: 100px;"/> <div style="border: 10px solid blue; width: 100px; height: 100px;"/> <div style="border: 10px solid black; width: 100px; height: 100px;"> <div style="border: 10px solid red; width: 100px; height: 100px;"> <div style="border: 10px solid blue; width: 100px; height: 100px;"/> </div> </div> </body> </html> I'm a bit confused what the point is of using XHTML if I have to do this, I might as well just use HTML? Note, that setting the content type to content="application/xhtml+xml" makes no difference in FF3 at least.
