  • Packaging reference documentation with jar file

    - by soren.enemaerke
    We are porting our .NET library to a java equivalent and is now looking at how to distribute this port. Packaging the classes into a jar-file seems like best practice and we would then ship this jar file in a zip along with some license terms. But what about the documentation? In .NET land it seems like best practice to distribute the xml file that can be consumed by tooling (Visual Studio) but we can't seem to find such best practices for java. We have javadoc comments on our public classes and interfaces, so we are just looking for a way to generate and distribute these comments in a way that is developer friendly (we're thinking easily consumed from various IDEs). What are developers expecting and how do you best deliver this? We would really prefer to bundle the documentation along with the jar file and not have to host the documentation on our website EDIT: We would like for our documentation to appear inside the java IDEs so we want to provide the documentation in a way that integrates into the IDEs as gracefully as possible. In .NET land this is as an xml file placed next to the .dll file, but is there a similar concept for jar files that enables the integration into tooling? PS: We are developing in Eclipse and have an ant task doing the building and jar-file packaing in our automated build.

  • web design question (php/ajax)

    - by tom smith
    Hi guys... Hope this isn't a waste of your time. I'm working on a project, and it occured to me that there's a chunk of code out there, that should allow me to see how others have implemented this. I've got a project where I'm going to have a page, with a sel box. the user will select an item from the selList, and based on the item selected, a separate section of the page (areaB) will change in terms of the content/tbls being displayed. i then want to allow the user to go through a series of subpages in areaB, where the user goes through a submit/cancel/confirm process, where the stuff in areaB changes, with the rest of the page remaining the same... i'm trying to figure out the best approach to implement the on both client/server side. i could just have an ugly "if block" where i have abunch of logic, and i completely regen the page each time the user selects an action.. i could have an approach that might involve divs/frames, where i then just regen the targeted frame/div area.. is this even possible?? i could have some form of ajaxy process, which would only alter the targeted section(s) of the page... so.. i'm trying to talk to anyone who has ideas on how to do this, or more ideally, if you know of a good code (client/server) side example of this... that i can examine. i'd really appreciate it!! i've got a more detailed overview but didn't know if it would be cool to post it here... thanks.. tom

  • Automated UAT/functional tests on Swing applications without source code

    - by jas
    Our team is now working on a big Swing application. Our job basically focuses on writing extensions to the existing framework. A typical job would be adding a new panel/ or adding a new tab with some extra functionalities that suit our need. It seems FEST can help a lot in terms of unit-test our code. I am going to try it out this week. But the question here is if there is a way to do automated functional testing on the whole application. In another word, we do not only need to test our code but also the framework. After all, UAT is the most important part. I am currently considering decompiling the jar files we got into source code then we can identify the components and then use FEST. So, before I get started to give this approach a shot, I think I just ask for ideas and inspirations here. There must be people who have done similar things before. Would be nice if I could learn from the veterans who fought against this before . Thanks,

  • Maximizing the number of true concurrent / parrallel http requests in Silverlight

    - by Clems
    Hi all. I'm using SL 4 beta and my app needs to do a lot of small http requests to the server. I believe that when exceeding the number of allowed concurrent requests, the subsequent requests are put in a queue. I am also aware that SL 4 has both a http browser stack and a http client stack, with both different limit in terms of the number of concurrent requests. Let's say call those limits MAX_BROWSER and MAX_CLIENT. Also I think I read somewhere that the number of concurrent requests is limited per domain, not overall. But I'm sure if this applies to both the http client stack. That means that you CAN have MAX_BROWSER requests to domain1.com AND MAX_BROWSER requests to domain2.com at the same time. And I even believe that sub domains are considered different so you can also have MAX_BROWSER requests to domain1.com AND MAX_BROWSER requests to sub.domain1.com at the same time. I have ownership of the services and domain names so I could easily setup sub domains for my services. Given those considerations I'm trying to optimize the number of concurrent http requests to my server. Here are few questions ? Is is possible to use both stack at the same time ? Is the subdomain/domain story true for both stacks ? None ? If so that would mean that I could potentially have a number of concurrent requests equal to : (MAX_BROWSER + MAX_CLIENT) * NUMBER_OF_DOMAINS which would be fairly good. Is this correct ? I'm kind of sharing my morning thoughts here, hoping somebody has experimented with those things. Thank you.

  • [C#][XNA 3.1] How can I host two different XNA windows inside one Windows Form?

    - by secutos
    I am making a Map Editor for a 2D tile-based game. I would like to host two XNA controls inside the Windows Form - the first to render the map; the second to render the tileset. I used the code here to make the XNA control host inside the Windows Form. This all works very well - as long as there is only one XNA control inside the Windows Form. But I need two - one for the map; the second for the tileset. How can I run two XNA controls inside the Windows Form? While googling, I came across the terms "swap chain" and "multiple viewports", but I can't understand them and would appreciate support. Just as a side note, I know the XNA control example was designed so that even if you ran 100 XNA controls, they would all share the same GraphicsDevice - essentially, all 100 XNA controls would share the same screen. I tried modifying the code to instantiate a new GraphicsDevice for each XNA control, but the rest of the code doesn't work. The code is a bit long to post, so I won't post it unless someone needs it to be able to help me. Thanks in advance.

  • Why linking doesn't work in my Xtext-based DSL?

    - by reprogrammer
    The following is the Xtext grammar for my DSL. Model: variableTypes=VariableTypes predicateTypes=PredicateTypes variableDeclarations= VariableDeclarations rules=Rules; VariableType: name=ID; VariableTypes: 'var types' (variableTypes+=VariableType)+; PredicateTypes: 'predicate types' (predicateTypes+=PredicateType)+; PredicateType: name=ID '(' (variableTypes+=[VariableType|ID])+ ')'; VariableDeclarations: 'vars' (variableDeclarations+=VariableDeclaration)+; VariableDeclaration: name=ID ':' type=[VariableType|ID]; Rules: 'rules' (rules+=Rule)+; Rule: head=Head ':-' body=Body; Head: predicate=Predicate; Body: (predicates+=Predicate)+; Predicate: predicateType=[PredicateType|ID] '(' (terms+=Term)+ ')'; Term: variable=Variable; Variable: variableDeclaration=[VariableDeclaration|ID]; terminal WS: (' ' | '\t' | '\r' | '\n' | ',')+; And, the following is a program in the above DSL. var types Node predicate types Edge(Node, Node) Path(Node, Node) vars x : Node y : Node z : Node rules Path(x, y) :- Edge(x, y) Path(x, y) :- Path(x, z) Path(z, y) When I used the generated Switch class to traverse the EMF object model corresponding to the above program, I realized that the nodes are not linked together properly. For example, the getPredicateType() method on a Predicate node returns null. Having read the Xtext user's guide, my impression is that the Xtext default linking semantics should work for my DSL. But, for some reason, the AST nodes of my DSL don't get linked together properly. Can anyone help me in diagnosing this problem?

  • F# List SelectMany

    - by Tuomas Hietanen
    This is quite simple question but I didn't find an answer: Is there any Seq/List operation in F# to match the LINQ SelectMany? I know I can use System.Linq in F# if I want to. I know I can make a recursive method and use F# Computation Expressions (and make even more powerful things). But if I try to prove that F# List operations are more powerful than LINQ... .Where = List.filter .Select = List.map .Aggregate = List.fold ... In C# SelectMany usage syntax is pretty simple: var flattenedList = from i in items1 from j in items2 select ... Is there any easy direct match, List.flatten, List.bind or something like that? SelectMany has a couple of signatures, but the most complex one seems to be: IEnumerable<TResult> SelectMany<TSource, TCollection, TResult>( this IEnumerable<TSource> source, Func<TSource, IEnumerable<TCollection>> collectionSelector, Func<TSource, TCollection, TResult> resultSelector ); In F# terms this would be: ('a -> 'b list) -> ('a -> 'b -> 'c) -> 'a list -> 'c list

  • Eclipse - Import existing mult-rep CVS project folder

    - by iQ
    Hey guys, Wondering if anyone can help me out with eclipse in terms of importing an existing CVS managed project. I am currently trying to shift my work on to the eclipse IDE. Some details about my project and environment below. I'm working in Linux Ubuntu, the project folder is located on a mounted shared network drive, I have installed the "Eclipse CVS Client" plug-in for my version of eclipse (helios). I've tried many ways for eclipse to use my existing folder as a project and recognize the CVS data in the CVS folders. I have done the following options: Created a new project, selected existing source, located my project folder and clicked OK to finish creating. In the end the CVS files weren't automatically read. Did the same as above and after project creation I wen to the option "project menu-team-share project", it asks me to choose a repository and doesn't automatically find the CVS information in the subfolders. If your wondering I have set-up both repositories in my eclipse and can browse the repositories through the CVS browser. My project directory layout is like this: +-Project Folder (no CVS folder at this level) +---Repo A folder +-----CVS meta-info folder is INSIDE, along with all checked out files from Repo A + +---Repo B folder +-----CVS meta-info folder is INSIDE, along with all checked out files from Repo B + +-(couple of random files, not in CVS) Thanks for the help

  • What is the best approach for creating a Common Information Model?

    - by Kaiser Advisor
    Hi, I would like to know the best approach to create a Common Information Model. Just to be clear, I've also heard it referred to as a canonical information model, semantic information model, and master data model - As far as I can tell, they are all referring to the same concept. I've heard in the past that a combined "top-down" and "bottom-up" approach is best. This has the advantage of incorporating "Ivory tower" architects and developers - The work will meet somewhere in the middle and usually be both logical and practical. However, this involves bringing in a lot of people with different skill sets. I've also seen a couple of references to the Distributed Management Task Force, but I can't glean much on best practices in terms of CIM development. This is something I'm quite interested in getting some feedback on since having a strong CIM is a prerequisite to SOA. Thanks for your help! KA Update I've heard another strategy goes along with overall SOA implementation: Get the business involved, and seek executive sponsorship. This would be part of the "Top-down" effort.

  • Passing data between ViewControllers versus doing local Fetch in each VC

    - by Tofrizer
    Hi All, I'm developing an iPhone app using Core Data and I'm looking for some general advice and recommendations on whether its acceptable to pass data between ViewControllers versus doing a local fetch in each ViewController as you navigate to it. Ordinarily I would say it all depends on various factors (e.g. performance etc) but the passing data approach is so prevalent in my app and I'm spooked by all the stories about Apple rejecting apps because of not conforming to their standard guidelines. So let me put another way -- is it non-standard to pass data between VC's? The reason I pass data so much is because each ViewController is just another view on to data present in my object model / graph. Once I have a handle on my first object in the first view controller (which I of course do have to fetch), I can use the existing object composition / relationships to drill down into the next level of detail into data and so I just pass these objects to the next VC. Separately, one possible downside with this passing-data-to-each-VC approach is I don't benefit from (what I perceive to be) the optimisation/benefits that NSFetchedResultsController provides in terms of efficient memory usage and section handling. My app is read-only but I do have one table with 5000 rows and I'm curious if I am missing out on NSFetchedResultsController benefits. Any thoughts on this as well? Can I somehow still benefit from NSFetchedResultsController goodness without having to do a full fetch (as I would have already passed in the data from my previous VC)? Thanks a lot.

  • Did the Unity Team fix that "generics handling" bug back in 2008?

    - by rasx
    At my level of experience with Unity it might be faster to ask whether the "generics handling" bug acknowledged by ctavares back in 2008 was fixed in a public release. Here was the problem (which might be my problem today): Hi, I get an exception when using .... container.RegisterType(typeof(IDictionary<,), typeof(Dictionary<,)); The exception is... "Resolution of the dependency failed, type = \"IDictionary2\", name = \"\". Exception message is: The current build operation (build key Build Key[System.Collections.Generic.Dictionary2[System.String,System.String], null]) failed: The current build operation (build key Build Key[System.Collections.Generic.Dictionary2[System.String,System.String], null]) failed: The type Dictionary2 has multiple constructors of length 2. Unable to disambiguate. When I attempt... IDictionary myExampleDictionary = container.Resolve(); Here was the moderated response: There are no books that'll help, Unity is a little too new for publishers to have caught up yet. Unfortunately, you've run into a bug in our generics handling. This is currently fixed in our internal version, but it'll be a little while before we can get the bits out. In the meantime, as a workaround you could do something like this instead: public class WorkaroundDictionary : Dictionary { public WorkaroundDictionary() { } } container.RegisterType(typeof(IDictionary<,),typeof(WorkaroundDictionary<,)); The WorkaroundDictionary only has the default constructor so it'll inject no problem. Since the rest of your app is written in terms of IDictionary, when we get the fixed version done you can just replace the registration with the real Dictionary class, throw out the workaround, and everything will still just work. Sorry about the bug, it'll be fixed soon!

  • Search and replace hundreds of strings in tens of thousands of files?

    - by C Johnson
    I am looking into changing the file name of hundreds of files in a (C/C++) project that I work on. The problem is our software has tens of thousands of files that including (i.e. #include) these hundreds of files that will get changed. This looks like a maintenance nightmare. If I do this I will be stuck in Ultra-Edit for weeks, rolling hundreds of regex's by hand like so: ^\#include.*["<\\/]stupid_name.*$ with #include <dir/new_name.h> Such drudgery would be worse than peeling hundreds of potatoes in a sunken submarine in the antarctic with a spoon. I think it would rather be ideal to put the inputs and outputs into a table like so: stupid_name.h <-> <dir/new_name.h> stupid_nameb.h <-> <dir/new_nameb.h> stupid_namec.h <-> <dir/new_namec.h> and feed this into a regular expression engine / tool / app / etc... My Ultimate Question: Is there a tool that will do that? Bonus Question: Is it multi-threaded? I looked at quite a few search and replace topics here on this website, and found lots of standard queries that asked a variant of the following question: standard question: Replace one term in N files. as opposed to: my question: Replace N terms in N files. Thanks in advance for any replies.

  • debugging scaffolding contingent upon degbugging boolean (java)

    - by David
    Recently i've found myself writing a lot of methods with what i can only think to call debugging scaffolding. Here's an example: public static void printArray (String[] array, boolean bug) { for (int i = 0; i<array.lenght; i++) { if (bug) System.out.print (i) ; //this line is what i'm calling the debugging scaffolding i guess. System.out.println(array[i]) ; } } in this method if i set bug to true, wherever its being called from maybe by some kind of user imput, then i get the special debugging text to let me know what index the string being printed as at just in case i needed to know for the sake of my debugging (pretend a state of affairs exists where its helpful). All of my questions more or less boil down to the question: is this a good idea? but with a tad bit more objectivity: Is this an effective way to test my methods and debug them? i mean effective in terms of efficiency and not messing up my code. Is it acceptable to leave the if (bug) stuff ; code in place after i've got my method up and working? (if a definition of "acceptability" is needed to make this question objective then use "is not a matter of programing controversy such as ommiting brackets in an if(boolean) with only one line after it, though if you've got something better go ahead and use your definition i won't mind) Is there a more effective way to accomplish the gole of making debugging easier than what i'm doing? Anything you know i mean to ask but that i have forgotten too (as much information as makes sense is appreciated).

  • How can I use Hibernate Criteria's to query nested tables?

    - by cbmeeks
    I've looked all over SO and Google but I guess I'm not using the right search terms or something. Anyway, say I have three tables: Companies ----------------------------------------- id name user_id Users ----------------------------------------- id username usertype_id UserTypes ----------------------------------------- id typeofuser So ACME would be a company, it would have a user Moe and Moe would be a usertype of Stooge. In SQL, I would do something like: select * from companies c join users u on (u.id = c.user_id) join usertypes ut on (ut.id = u.usertype_id) where ut.typeofuser = 'Stooge' But I can't seem to figure out how to do that in a Criteria. I have tried: Criteria crit = io.getSession().createCriteria(Company.class); List<Company> list = crit.createCriteria("users") .createCriteria("usertypes") .add(Restriction.eq("typeofuser", "Stooge").list(); But I get back way too many records. And the results don't even come close to being accurate. I've also tried: Criteria crit = io.getSession().createCriteria(Company.class); List<Company> list = crit.createAlias("users", "u") .createAlias("u.usertypes", "ut") .add(Restriction.eq("ut.typeofuser", "Stooge").list(); Seems to bring back the exact same result set. I actually have read the user manual. And when I nest only one level deep (ie, searching by users is fine) but when I get two layers deep, I can't quite get it. And the manual is no help. I just can't relate cats and kittens to business objects. Maybe they should use cats, kittens and fleas? :-/ Thanks for any suggestions.

  • MS Access 2003 - Is there a way to programmatically define the data for a chart?

    - by Justin
    So I have some VBA for taking charts built with the Form's Chart Wizard, and automatically inserting it into PowerPoint Presentation slides. I use those chart-forms as sub forms within a larger forms that has parameters the user can select to determine what is on the chart. The idea is that the user can determine the parameter, build the chart to his/her liking, and click a button and have it in a ppt slide with the company's background template, blah blah blah..... So it works, though it is very bulky in terms of the amount of objects I have to use to accomplish this. I use expressions such as the following: like forms!frmMain.Month&* to get the input values into the saved queries, which was fine when i first started, but it went over so well and they want so many options, that it is driving the number of saved queries/objects up. I need several saved forms with charts because of the number of different types of charts I need to have this be able to handle. SO FINALLY TO MY QUESTION: I would much rather do all this on the fly with some VBA. I know how to insert list boxes, and text boxes on a form, and I know how to use SQL in VBA to get the values I want from tables/queries using VBA, I just don't know if there is some vba I can use to set the data values of the charts from a resulting recordset: DIM rs AS DAO.Rescordset DIM db AS DAO.Database DIM sql AS String sql = "SELECT TOP 5 Count(tblMain.TransactionID) AS Total, tblMain.Location FROM tblMain WHERE (((tblMain.Month) = """ & me.txtMonth & """ )) ORDER BY Count (tblMain.TransactionID) DESC;" set db = currentDB set rs = db.OpenRecordSet(sql) rs.movefirst some kind of cool code in here to make this recordset the data of chart in frmChart ("Chart01") thanks for your help. apologies for the length of the explanation.

  • Theory: "Lexical Encoding"

    - by _ande_turner_
    I am using the term "Lexical Encoding" for my lack of a better one. A Word is arguably the fundamental unit of communication as opposed to a Letter. Unicode tries to assign a numeric value to each Letter of all known Alphabets. What is a Letter to one language, is a Glyph to another. Unicode 5.1 assigns more than 100,000 values to these Glyphs currently. Out of the approximately 180,000 Words being used in Modern English, it is said that with a vocabulary of about 2,000 Words, you should be able to converse in general terms. A "Lexical Encoding" would encode each Word not each Letter, and encapsulate them within a Sentence. // An simplified example of a "Lexical Encoding" String sentence = "How are you today?"; int[] sentence = { 93, 22, 14, 330, QUERY }; In this example each Token in the String was encoded as an Integer. The Encoding Scheme here simply assigned an int value based on generalised statistical ranking of word usage, and assigned a constant to the question mark. Ultimately, a Word has both a Spelling & Meaning though. Any "Lexical Encoding" would preserve the meaning and intent of the Sentence as a whole, and not be language specific. An English sentence would be encoded into "...language-neutral atomic elements of meaning ..." which could then be reconstituted into any language with a structured Syntactic Form and Grammatical Structure. What are other examples of "Lexical Encoding" techniques? If you were interested in where the word-usage statistics come from : http://www.wordcount.org

  • When is it better to use a method versus a property for a class definition?

    - by ccomet
    Partially related to an earlier question of mine, I have a system in which I have to store complex data as a string. Instead of parsing these strings as all kinds of separate objects, I just created one class that contains all of those objects, and it has some parser logic that will encode all properties into strings, or decode a string to get those objects. That's all fine and good. This question is not about the parser itself, but about where I should house the logic for the parser. Is it a better choice to put it as a property, or as a method? In the case of a property, say public string DataAsString, the get accessor would house the logic to encode all of the data into a string, while the set accessor would decode the input value and set all of the data in the class instance. It seems convenient because the input/output is indeed a string. In the case of a method, one method would be Encode(), which returns the encoded string. Then, either the constructor itself would house the logic for the decoding a string and require the string argument, or I write a Decode(string str) method which is called separately. In either case, it would be using a method instead of a property. So, is there a functional difference between these paths, in terms of the actual running of the code? Or are they basically equivalent and it then boils down to a choice of personal preference or which one looks better? And in that kind of question... which would look cleaner anyway?

  • jQuery tooltip: Trouble with remove()

    - by Rosarch
    I'm using a jQuery tooltip plugin. I have HTML like this: <li class="term ui-droppable"> <strong>Fall 2011</strong> <li class="course ui-draggable">Biological Statistics I<a class="remove-course-button" href="">[X]</a></li> <div class="term-meta-data"> <p class="total-credits too-few-credits">Total credits: 3</p> <p class="median-GPA low-GPA">Median Historical GPA: 2.00</p> </div> </li> I want to remove the .course element. So, I attach a click handler to the <a>: function _addDeleteButton(course, term) { var delete_button = $('<a href="" class="remove-course-button" title="Remove this course">[X]</a>'); course.append(delete_button); $(delete_button).click(function() { course.remove(); return false; }).tooltip(); } This all works fine, in terms of attaching the click handler. However, when course.remove() is called, Firebug reports an error in tooltip.js: Line 282 tsettings is null if ((!IE || !$.fn.bgiframe) && tsettings.fade) { What am I doing wrong? If the link has a tooltip attached, do I need to remove it specially? UPDATE: Removing .tooltip() solve the problem. I'd like to keep it in, but that makes me suspect that my use of .tooltip() is incorrect here.

  • Separating Javascript functions

    - by msharma
    I am wondering how javascripts get included in a jsp - can we put any code which the jsp will recognize and not just javascript code only in the .js file? I have some common javascript code which needs to get executed on different pages, so I decided to place it in its own separate .js file and include it on all jsps which call that function. The js function now refers to a key from a properties file and some other non-javascript code: function openPrivacyStmntWindow(){ var url = <h:outputText escape="false" value="\"#{urls.url_privacyStatement}\";" /> newwindow=window.open(url,'Terms','height=600,width=800,left=300,top=100,scrollbars=1'); newwindow.focus(); return false; } This function worked just fine when it was included in the jsp itself. Now that I have separated it into its own file it doesnt, do I need to include the properties bundle in this file. The value="\"#{urls.url_privacyStatement}\";" is referring to a bundle called "urls" which has a key called "url_privacyStatement" Also in Line 1 var url = <h:outputText escape="false" value="\"#{urls.url_privacyStatement}\";" /> the <h:outputText escape="false" ... /> will it cause any issues? Thanks.

  • Distributed Message Ordering

    - by sbanwart
    I have an architectural question on handling message ordering. For purposes of this question, the transport is irrelevant, so I'm not going to specify one. Say we have three systems, a website, a CRM and an ERP. For this example, the ERP will be the "master" system in terms of data ownership. The website and the CRM can both send a new customer message to the ERP system. The ERP system then adds a customer and publishes the customer with the newly assigned account number so that the website and CRM can add the account number to their local customer records. This is a pretty straight forward process. Next we move on to placing orders. The account number is required in order for the CRM or website to place an order with the ERP system. However the CRM will permit the user to place an order even if the customer lacks an account number. (For this example assume we can't modify the CRM behavior) This creates the possibility that a user could create a new customer, and place an order before the account number gets updated in the CRM. What is the best way to handle this scenario? Would it be best to send the order message sans account number and let it go to an error queue? Would it be better to have the CRM endpoint hold the message and wait until the account number is updated in the CRM? Maybe something completely different that I haven't thought of? Thanks in advance for any help.

I need my program to show different parts of the data contained in a txt file into different listboxs (which are on different tabs of a form) so that the user can see the particular block of data they are interested in. the data contained in the txt file looks like this: G30:39:03:31 JG06 G32:56:36:10 JG04 G31:54:69:52 JG04 G36:32:53:11 JG05 G33:50:05:11 JG06 G39:28:81:21 JG01 G39:22:74:11 JG06 G39:51:44:21 JG03 G39:51:52:22 JG01 G39:51:73:21 JG01 G35:76:24:20 JG06 G35:76:55:11 JG01 G36:31:96:11 JG02 G36:31:96:23 JG02 G36:31:96:41 JG03 though much more of it :) The separate listboxes will contain only the lines who's first integer pair matches that listbox's name. For example, all the lines that start "G32" will be added to the G32 listbox. I think the code would start something like: private void ReadToBox() { FileInfo file = new FileInfo("Jumpgate List.JG"); StreamReader objRead = file.OpenText(); while (!objRead.EndOfStream) but i'm not sure where to start in terms of getting it sorted yet. Any help? There's some rep in it for you :D

  • Center aligned form with equal width labels

    - by James Goodwin
    I have a very simple web form which consists of labels and input fields, however I can not seem to find a way of aligning the form in the center of the page and for the labels to have an equal width so that they appear neatly next to each other, one under the other. The structure of my page is basically: <body> <div class="form"> <form method="post"> <fieldset> <label>Mobile:</label><input type="text" name="msisdn"><br/> <label>Code:</label><input type="text" name="code"><br/> <br/> <input type="image" src="submit-button.gif" alt="Submit"> <br/> <input type="checkbox" name="ts_and_cs"><label> Accept Terms and Conditions</label> <br/><br/> </fieldset> </form> </div> </body> Usually I would fix this by doing float:left on the label fields and setting a width on the labels, however for this I need the labels and input fields to be centered on the page. Also I am not able to set the width of the page (or any containing divs) as the page will be displayed on mobile devices with different screen sizes. Any suggestions as to how best style the form? Thanks

  • Stata Nearest neighbor of percentile

    - by Kyle Billings
    This has probably already been answered, but I must just be searching for the wrong terms. Suppose I am using the built in Stata data set auto: sysuse auto, clear and say for example I am working with 1 independent and 1 dependent variable and I want to essentially compress down to the IQR elements, min, p(25), median, p(75), max... so I use command, keep weight mpg sum weight, detail return list local min=r(min) local lqr=r(p25) local med = r(p50) local uqr = r(p75) local max = r(max) keep if weight==`min' | weight==`max' | weight==`med' | weight==`lqr' | weight==`uqr' Hence, I want to compress the data set down to only those 5 observations, and for example in this situation the median is not actually an element of the weight vector. there is an observation above and an observation below (due to the definition of median this is no surprise). is there a way that I can tell stata to look for the nearest neighbor above the percentile. ie. if r(p50) is not an element of weight then search above that value for the next observation? The end result is I am trying to get the data down to 2 vectors, say weight and mpg such that for each of the 5 elements of weight in the IQR have their matching response in mpg. Any thoughts?

  • Can a C# method chain be "too long"?

    - by ccornet
    Not in terms of readability, naturally, since you can always arrange the separate methods into separate lines. Rather, is it dangerous, for any reason, to chain an excessively large number of methods together? I use method chaining primarily to save space on declaring individual one-use variables, and traditionally using return methods instead of methods that modify the caller. Except for string methods, those I kinda chain mercilessly. In any case, I worry sometimes about the impact of using exceptionally long method chains all in one line. Let's say I need to update the value of one item based on someone's username. Unfortunately, the shortest method to retrieve the correct user looks something like the following. SPWeb web = GetWorkflowWeb(); SPList list2 = web.Lists["Wars"]; SPListItem item2 = list2.GetItemById(3); SPListItem item3 = item2.GetItemFromLookup("Armies", "Allied Army"); SPUser user2 = item2.GetSPUser("Commander"); SPUser user3 = user2.GetAssociate("Spouse"); string username2 = user3.Name; item1["Contact"] = username2; Everything with a 2 or 3 lasts for only one call, so I might condense it as the following (which also lets me get rid of a would-be-superfluous 1): SPWeb web = GetWorkflowWeb(); item["Contact"] = web.Lists["Armies"] .GetItemById(3) .GetItemFromLookup("Armies", "Allied Army") .GetSPUser("Commander") .GetAssociate("Spouse") .Name; Admittedly, it looks a lot longer when it is all in one line and when you have int.Parse(ddlArmy.SelectedValue.CutBefore(";#", false)) instead of 3. Nevertheless, this is one of the average lengths of these chains, and I can easily foresee some of exceptionally longer counts. Excluding readability, is there anything I should be worried about for these 10+ method chains? Or is there no harm in using really really long method chains?
