    - by Anil Namde
    Hi all, Just another day i found myself writing code to show data on the UI. I am again using DataGrid/GridView (ASP.NET), User Id as link button (clickable) to redirect user to another page. User having hard time to find where to click(Though the link has underline and hand pointer as usual on hover) just another common table like structure Following are the columns for example, User ID (Link button), User Name, First Name, Last Name, Date Of Birth Now i would like to make it better form the usability point of view.

  • A better way to build this MySQL statement with subselects

    - by Corey Maass
    I have five tables in my database. Members, items, comments, votes and countries. I want to get 10 items. I want to get the count of comments and votes for each item. I also want the member that submitted each item, and the country they are from. After posting here and elsewhere, I started using subselects to get the counts, but this query is taking 10 seconds or more! SELECT `items_2`.*, (SELECT COUNT(*) FROM `comments` WHERE (comments.Script = items_2.Id) AND (comments.Active = 1)) AS `Comments`, (SELECT COUNT(votes.Member) FROM `votes` WHERE (votes.Script = items_2.Id) AND (votes.Active = 1)) AS `votes`, `countrys`.`Name` AS `Country` FROM `items` AS `items_2` INNER JOIN `members` ON items_2.Member=members.Id AND members.Active = 1 INNER JOIN `members` AS `members_2` ON items_2.Member=members.Id LEFT JOIN `countrys` ON countrys.Id = members.Country GROUP BY `items_2`.`Id` ORDER BY `Created` DESC LIMIT 10 My question is whether this is the right way to do this, if there's better way to write this statement OR if there's a whole different approach that will be better. Should I run the subselects separately and aggregate the information?

  • How to write this in better way?

    - by dario
    Hi all. Let's look at this code: IList<IHouseAnnouncement> list = new List<IHouseAnnouncement>(); var table = adapter.GetData(); //get data from repository object -> DataTable if (table.Rows.Count >= 1) { for (int i = 0; i < table.Rows.Count-1; i++) { var anno = new HouseAnnouncement(); anno.Area = float.Parse(table.Rows[i][table.powierzchniaColumn].ToString()); anno.City = table.Rows[i][table.miastoColumn].ToString(); list.Add(anno); } } return list; Is it better way to write this in less code and better fashion (must be :-) )? Maybe using labda (but let mi know how)? Thanks in advance!

  • Question about software that tracks divs better than notepad++

    - by Jeff
    I recently got hired as a web developer, and the project that I am overseeing has a formatting issue on one of the pages because one of the divs is out of whack. It is a fairly complex page with quite a bit of php, and from what I can gather, I am missing a </div> tag somewhere, and accordingly everything is messed up. I am currently using notepad++, which is decent at lining up divs, meaning that if you click on the opening div tag, it will highlight purple and also highlight the closing one. But it seems as though if you have div tags that span several lines (hundreds) it won't work. Has anyone else run into a similar situation? Is there a better editor I could be using that would do a better job of helping me with my div issue? Or do I have to go through and line up the divs 1 by 1? (there are like over 100). Please let me know!! Thanks

  • Is there any better IDOMImplementation other than MSXML?

    - by Chau Chee Yang
    There are 3 IDOMImplementation available in Delphi: MSXML Xerces XML ADOM XML v4 MSXML is the default IDOMImplementation. My test is count the time need to load a 10MB xml file. I use a Delphi unit generated from a XSD using XML data binding to load the xml file. This unit has 3 common function: function Getmenubar(Doc: IXMLDocument): IXMLMenubarType; function Loadmenubar(const FileName: WideString): IXMLMenubarType; function Newmenubar: IXMLMenubarType; I learn from the web that some comment that MSXML's overhead is high that it doesn't perform if compare to other XML parser. However, my study shows that MSXML is the best among others. Xerces XML 2nd and ADOM XML v4 the worst: MSXML - 0.6410 seconds Xerces XML - 2.4220 seconds ADOM XML v4 - 67.50 seconds I also come across with OmniXML that claim to have much better performance compare to MSXML but I never success using it with the unit generated by XML data binding. Is there any other vendor that implement IDOMImplementation of Delphi that work much better than MSXML? I am using Delphi 2010 and Windows 7.

  • UX question: is better to have "serious delete" or have "trash"

    - by ftrotter
    I am developing an application that allows for a user to manage some individual data points. One of the things that my users will want to do is "delete" but what should that mean? For a web application is it better to present a user with the option to have serious delete or to use a "trash" system? Under "serious delete" (would love to know if there is a better name for this...) you click "delete" and then the user is warned "this is final and tragic action. Once you do this you will not be able to get -insert data point name here- back, even if you are crying..." Then if they click delete... well it truly is gone forever. Under the "trash" model, you never trust that the user really wants to delete... instead you remove the data point from the "main display" and put into a bucket called "the trash". This gets it out of the users way, which is what they usually want, but they can get it back if they make a mistake. Obviously this is the way most operating systems have gone. The advantages of "serious delete" are: Easy to implement Easy to explain to users The disadvantages of "serious delete" are: it can be tragically final sometimes, cats walk on keyboards The advantages of the "trash" system are: user is safe from themselves bulk methods like "delete a bunch at once" make more sense saves support headaches The disadvantages of the "trash" system are": For sensitive data, you create an illusion of destruction users think something is gone, but it is not. Lots of subtle distinctions make implementation more difficult Do you "eventually" delete the contents of the trash? My question is which one is the right design pattern for modern web applications? With enough discussion to justify your answer... Would love to be pointed towards some relevant research. -FT

  • I set up better-edit-in-place but still cannot edit in place in Rails

    - by Angela
    I installed the plugin better-edit-in-place (http://github.com/nakajima/better-edit-in-place) but I dont' seem to be able to make it work. When I use firebug, it is rendering the value to be edited correctly: <span rel="/emails/1" id="email_1_days" class="editable">7</span> And it is showing the full javascript which should work on class editable: var Editable = Class.create({ 5 initialize: function(element, options) { 6 this.element = $(element); 7 Object.extend(this, options); 8 9 // Set default values for options 10 this.editField = this.editField || {}; 11 this.editField.type = this.editField.type || 'input'; 12 this.onLoading = this.onLoading || Prototype.emptyFunction; 13 this.onComplete = this.onComplete || Prototype.emptyFunction; 14 15 this.field = this.parseField(); 16 this.value = this.element.innerHTML; 17 18 this.setupForm(); 19 this.setupBehaviors(); 20 }, 21 22 // In order to parse the field correctly, it's necessary that the element 23 // you want to edit in place for have an id of (model_name)_(id)_(field_name). 24 // For example, if you want to edit the "caption" field in a "Photo" model, 25 // your id should be something like "photo_#{@photo.id}_caption". 26 // If you want to edit the "comment_body" field in a "MemberBlogPost" model, 27 // it would be: "member_blog_post_#{@member_blog_post.id}_comment_body" 28 parseField: function() { 29 var matches = this.element.id.match(/(.*)_\d*_(.*)/); 30 this.modelName = matches[1]; 31 this.fieldName = matches[2]; 32 if (this.editField.foreignKey) this.fieldName += '_id'; 33 return this.modelName + '[' + this.fieldName + ']'; 34 }, But when I point my mouse at the element, no in-place-editing action!

  • Which of these is better practice?

    - by Fletcher Moore
    You have a sequence of functions to execute. Case A: They do not depend on each other. Which of these is better? function main() { a(); b(); c(); } or function main() { a(); } function a() { ... b(); } function b() { ... c(); } Case B: They do depend on successful completion of the previous. function main() { if (a()) if (b()) c(); } or function main() { if (!a()) return false; if (!b()) return false; c(); } or function main() { a(); } function a() { ... // maybe return false b(); } funtion b() { ... // maybe return false c(); } Better, of course, means more maintainable and easier to follow.

  • Better use a tuple or numpy array for storing coordinates

    - by Ivan
    Hi, I'm porting an C++ scientific application to python, and as I'm new to python, some problems come to my mind: 1) I'm defining a class that will contain the coordinates (x,y). These values will be accessed several times, but they only will be read after the class instantiation. Is it better to use an tuple or an numpy array, both in memory and access time wise? 2) In some cases, these coordinates will be used to build a complex number, evaluated on a complex function, and the real part of this function will be used. Assuming that there is no way to separate real and complex parts of this function, and the real part will have to be used on the end, maybe is better to use directly complex numbers to store (x,y)? How bad is the overhead with the transformation from complex to real in python? The code in c++ does a lot of these transformations, and this is a big slowdown in that code. 3) Also some coordinates transformations will have to be performed, and for the coordinates the x and y values will be accessed in separate, the transformation be done, and the result returned. The coordinate transformations are defined in the complex plane, so is still faster to use the components x and y directly than relying on the complex variables? Thank you

  • Better language or checking tool?

    - by rwallace
    This is primarily aimed at programmers who use unmanaged languages like C and C++ in preference to managed languages, forgoing some forms of error checking to obtain benefits like the ability to work in extremely resource constrained systems or the last increment of performance, though I would also be interested in answers from those who use managed languages. Which of the following would be of most value? A language that would optionally compile to CLR byte code or to machine code via C, and would provide things like optional array bounds checking, more support for memory management in environments where you can't use garbage collection, and faster compile times than typical C++ projects. (Think e.g. Ada or Eiffel with Python syntax.) A tool that would take existing C code and perform static analysis to look for things like potential null pointer dereferences and array overflows. (Think e.g. an open source equivalent to Coverity.) Something else I haven't thought of. Or put another way, when you're using C family languages, is the top of your wish list more expressiveness, better error checking or something else? The reason I'm asking is that I have a design and prototype parser for #1, and an outline design for #2, and I'm wondering which would be the better use of resources to work on after my current project is up and running; but I think the answers may be useful for other tools programmers also. (As usual with questions of this nature, if the answer you would give is already there, please upvote it.)

  • How to be a better software designer

    - by Bmw
    I feel as if I am a hack programmer. I do things over and over again until they finally work. I copy/paste code. I don't think about why something makes sense, if it works I go with it. I have my undergraduate in computer science, and I've done this the entire time. Somehow I made it through the degree by doing this and now I'm in my second year of programming professionally and I am still able to do this and get away with it. Here's the thing, I don't want to be this way anymore. I am not proud of the work I do, I feel like I'm just a copy/paste programmer. How do I become better? I want to be able to design something on my own without copying code. Have you ever been in this situation, if so how did you move beyond it to become a better programmer? To add some background about myself, I started as an asp.net c# programmer, now I'm doing vbscript (which actually makes my tendency to copy/paste/hack a lot worse I must say!) with classic asp…

  • A better way of handling the below program(may be with Take/Skip/TakeWhile.. or anything better)

    - by Newbie
    I have a data table which has only one row. But it is having 44 columns. My task is to get the columns from the 4th row till the end. Henceforth, I have done the below program that suits my requirement. (kindly note that dt is the datatable) List<decimal> lstDr = new List<decimal>(); Enumerable.Range(0, dt.Columns.Count).ToList().ForEach(i => { if (i > 3) lstDr.Add(Convert.ToDecimal(dt.Rows[0][i])); } ); There is nothing harm in the program. Works fine. But I feel that there may be a better way of handimg the program may be with Skip ot Take or TakeWhile or anyother stuff. I am looking for a better solution that the one I implemented. Is it possible? I am using c#3.0 Thanks.

  • Becoming a better Android programmer

    - by Drew Dara-Abrams
    Any suggestions on how to become a better Android programmer? I'm past intro tutorials, which mainly focus on how to use pieces of the SDK, but I still struggle to structure big Android apps. Obviously the best use of my time is continuing with my coding projects, but I'm wondering if I should be learning more about Android particulars, solidifying my somewhat shaky Java knowledge, going back to object-oriented fundamentals or patterns...? Pointers to resources (books, example apps, sites) you've found helpful would be great.

  • NAnt or TFS build which is better?

    - by Leszek Wachowicz
    There was a question about Msbuild and NAnt advantages and disadvantages. Now let's see which is better TFS Build(with msbuild) or NAnt. In my opinion NAnt because you can easily move the building environment in few seconds to another machine (depends on copying files), also it's easier to manage, much faster to debug and it's not integrated with Team Foundation Server, what do You think?
