  • Shouldn't we ignore IE6 and IE7 users?

    - by Sebi
    Lately I created two webpages with a simple CMS for a a small club and a private person (http://foto.roser.li and http://www.ovlu.li/cms). I dont really understand much of HTML/PHP/CSS and all this web stuff, but it was enough to adapt the stylesheets and add some javascript functions and so on to make the pages to look more or less nice in firefox and IE8. Nevertheles, if you open the pages with IE7 or IE6, particulary the second home page really looks terrible. So what should I do know? I don't have the know-how to adapt the stylesheets so that it looks good at such browsers. However if I check the statistics of the pages, i noticed that almost half of the visitors uses this kind of browsers. I could put much effort in adapting the stylesheets to look good at all browser but while thinking about this I'm asking myself if this is really the best way. If all developers put effort in providing solutions for really old browsers (like e.g. the IE6), then people who use these brwoser dont have any incentives to update their browsers. Naturally, I as a provider of information should present the content in a readable form to my users, but were should i draw the line? I also saw that some users are visiting the pages with even IE5 or IE4... but I really can't think of a way how to adapt the content in a suitable form for these very old brwosers. I would appreciaed any hints how to handle this balancing between putting much effort into developing a version for very old brwosers and the necessity of providing content to all users which want to visits my homepages. Im also interested in your thoughts about they idea that putting effort in adapting the content for old browsers prevents the users from updating their browsres because they don't see any need.

    Hi, Im building a web application that displays a xfdf document. When we are testing in adobe 5 and we can't stop adobe opening outside the webpage. The user clicks the report and it should open in the browser but instead it opens in adobe it appears to work in everything but adobe 5. We have previously done this with out any problems. Any ideas?

  • jQuery $.each()-problem

    - by Volmar
    Hi, im making a wordpress plugin and i have a function where i import images, this is done with a $.each()-loop that calls a .load()-function every iteration. The load-function page the load-function calls is downloading the image and returns a number. The number is imported into a span-element. The source and destination Arrays is being imported from LI-elemnts of a hidden ULs. this way the user sees a counter counting from zero up to the total number of images being imported. You can se my jQuery code below: jQuery(document).ready(function($) { $('#mrc_imp_img').click(function(){ var dstA = []; var srcA = []; $("#mrc_dst li").each(function() { dstA.push($(this).text()) }); $("#mrc_src li").each(function() { srcA.push($(this).text()) }); $.each(srcA, function (i,v) { $('#mrc_imgimport span.fc').load('/wp-content/plugins/myplugin/imp.php?num='+i+'&dst='+dstA[i]+'&src='+srcA[i]); }); }); }); This works pretty good but sometimes it looks like the load function isn't updating the DOM as fast as it should because sometimes the numbers that the span is updated with is lower than the previous and almost everytime a lower number is replacing the last number in the end. How can i prevent this from happening and how can i make it hide '#mrc_imp_img' when the $.each-loop is ready?

  • Rails - Beginner wants feedback on how they've modeled their app and how to do it better.

    - by adam
    I think the way I've modelled my app is a bit fishy and i need to rejig things, im just not sure how. I've already re-jigged and refactored before. It took a long time ( I'm a beginner ) and I'm hesitant to it again in case i head off in the wrong direction again. Basic Idea, user can submit an answer, another user can mark it correct or incorrect. If incorrect they have to write the correct answer. Users can view their and everybody else's correct and incorrect answers. So I did it this way class Answer has_one: correction end class Correction belongs_to :answer end when a user marks an answer as correct, I set checked_at:DateTime and checked_by_id:integer on the Answer object to keep track of who checked the answer and when. For incorrect answers I create a correction object which holds the correct answer and again checked_by and checked_at details. I don't like this because I have checked_by and checked_at in both models. It just doesn't sit right. Possible solutions are: Create a third model such as VerifiedAnswer and move the checked_by/at attributes to that. It will handle the situtation where an answer is marked correct. Or are these models thin enough (they dont have any other attributes) that I can just have one model ( Answer ) that has all the attributes to store all this information?

  • Python OOP - object has no attribute

    - by user1744269
    I am attempting to learn how to program. I really do want to learn how to program; I love the building and design aspect of it. However, in Java and Python, I have tried and failed with programs as they pertain to objects, classes, methods.. I am trying to develop some code for a program, but im stumped. I know this is a simple error. However I am lost! I am hoping someone can guide me to a working program, but also help me learn (criticism is not only expected, but APPRECIATED). class Converter: def cTOf(self, numFrom): numFrom = self.numFrom numTo = (self.numFrom * (9/5)) + 32 print (str(numTo) + ' degrees Farenheit') return numTo def fTOc(self, numFrom): numFrom = self.numFrom numTo = ((numFrom - 32) * (5/9)) return numTo convert = Converter() numFrom = (float(input('Enter a number to convert.. '))) unitFrom = input('What unit would you like to convert from.. ') unitTo = input('What unit would you like to convert to..

  • Hibernate Performance Best Practice?

    - by user829237
    Im writing a Web application using Hibernate 3. So, after a while i noticed that something was slow. So i tested hibernate profiler and found that hibernate will make unreasonably many db-calls for simple operation. The reason is ofcourse that i load an Object (this object has several "parents") and these "parents" have other "parents". So basicly hibernate loads them all, even though i just need the basic object. Ok, so i looked into lazy-loading. Which lead me into the Lazyloading-exception, because i have a MVC webapp. So now i'm a bit confused as to what is my best approach to this. Basicly all I need is to update a single field on an object. I already have the object-key. Should I: 1. Dig into Lazy-loading. And then rewrite my app for a open-session-view? 2. Dig into lazy-loading. And then rewrite my dao's to be more specific. E.g. writing DAO-methods that will return objects instanciated with only whats necessary for each use-case? Could be a lot of extra methods... 3. Scratch hibernate and do it myself? 4. Cant really think of other solutions right now. Any suggestions? What is the best practice?

  • learning C++ from java, trying to make a linked list.

    - by kyeana
    I just started learning c++ (coming from java) and am having some serious problems with doing anything :P Currently, i am attempting to make a linked list, but must be doing something stupid cause i keep getting "void value not ignored as it ought to be" compile errors (i have it marked where it is throwing it bellow). If anyone could help me with what im doing wrong, i would be very grateful :) Also, I am not used to having the choice of passing by reference, address, or value, and memory management in general (currently i have all my nodes and the data declared on the heap).

  • PHP session token can be used multipletimes?

    - by kornesh
    I got page A which is a normal HTML page and page which is an AJAX response page. And I want to prevent CSRF attacks by tokens. Lets say I use this method for an autocomplete form, is it possible to use same token multiple times (of course the session is only set one time) because i tired this method but the validation keep failing after the first suggestion (obviously the token has changed, somehow) page A <?php session_start(); $token = md5(uniqid(rand(), TRUE)); $_SESSION['token'] = $token; ?> <input id="token" value="<?php echo $token; ?>" type="hidden"></input> <input id="autocomplete" placeholder="Type something"></input> .... The form is autosubmitted every time theres a change using Jquery. page B <?php session_start(); if($_REQUEST['token'] == $_SESSION['token']){ echo 'Im working fine'; } ?>

  • Linq2Sql - attempting to update but the Set statement in sql is empty

    - by MrTortoise
    This is weird ... done updates loads of times before but cannot spot why this is different. I have a client class from the dbml I added a method called update public void UpdateSingle() { L2SDataContext dc = new L2SDataContext(); Client c = dc.Clients.Single<Client>(p => p.ID == this.ID); c.CopyToMe(this); c.updatedOn = DateTime.Now; dc.SubmitChanges(); dc.Dispose(); } The CopytoMe method public void CopyToMe(Client theObject) { if (ID != theObject.ID) { ID = theObject.ID; } /// this is redundant as generated code checks field for a change. deleted = theObject.deleted; deletedBy = theObject.deletedBy; deletedOn = theObject.deletedOn; insertedBy = theObject.insertedBy; insertedOn = theObject.insertedOn; name = theObject.name; updatedBy = theObject.updatedBy; updatedOn = theObject.updatedOn; } Im taking a client that was selected, changing its name and then calling this update method. The generated sql is as follows exec sp_executesql N'UPDATE [dbo].[tblClient] SET WHERE ([ID] = @p0) AND ([name] = @p1) AND ([insertedOn] = @p2) AND ([insertedBy] = @p3) AND ([updatedOn] = @p4) AND ([updatedBy] = @p5) AND ([deletedOn] IS NULL) AND ([deletedBy] IS NULL) AND (NOT ([deleted] = 1))',N'@p0 int,@p1 varchar(8000),@p2 datetime,@p3 int,@p4 datetime,@p5 int',@p0=103,@p1='UnitTestClient',@p2=''2010-05-17 11:33:22:520'',@p3=3,@p4=''2010-05-17 11:33:22:520'',@p5=3 I have no idea why this is not working ... used this kind of select object, set field to new value submit the selected object pattern many times and not had this problem. there is also nothing obviously wrong with the dbml - although this is probably a false statement any ideas?

  • Confusion about pointers and their memory addresses

    - by TimothyTech
    alright, im looking at a code here and the idea is difficult to understand. #include <iostream> using namespace std; class Point { public : int X,Y; Point() : X(0), Y(0) {} }; void MoveUp (Point * p) { p -> Y += 5; } int main() { Point point MoveUp(&point) cout <<point.X << point.Y; return 0; } Alright, so i believe that a class is created and X and Y are declared and they are put inside a constructor a method is created and the argument is Point * p, which means that we are going to stick the constructor's pointer inside the function; now we create an object called point then call our method and put the pointers address inside it? isnt the pointers address just a memory number like 0x255255? and why wasnt p ever declared? (int * p = Y) what is a memory addres exactly? that it can be used as an argument?

  • changing the intensity of lighten/darken on bitmaps using PorterDuffXfermode in the Android Paint class

    - by user1116836
    Ok my orignal question has changed. How do i change the intensity of how something like this is effected? DayToNight.setXfermode(new PorterDuffXfermode(Mode.DST_IN)); in my dream world it would have worked like this DayToNight.setXfermode(new PorterDuffXfermode(Mode.DST_IN(10))); the 10 being a level of intensity. An example would be if I had a flickering candle, when the candle burns bright I want the bitmaps I am drawing to the screen to retain their origanol color and brightness, when it flickers I want the bitmaps to be almost blacked out, and I want to darken the Bitmaps as the light dims. I have equations, timers and all that figured out, just not how to actually apply it to change the color/brightness. Maybe burning the images is what im looking for? I just want to change the lightness lol. I feel like using paint.setShader might be a solution, but the information in this area is pretty limited from what i have been able to find. Any help would be appreciated. edit: to be crystal clear, i am looking for a way to lighten/darken bitmaps as I draw them to the canvas

  • SQL Trigger Need to set x from a value

    - by Eric
    Im stuck on a the type of trigger needed to for this constraint. I will have a price and a commission. The price determines the commission amount, < 100 - 4%, < 200 - 5% etc. My idea. the database contains a separate table that will hold 4 price values , 101, 201, 401, 601, with their own matching comission %, this will be called PC. When i create a property listing i want to calculate the commission they earn depending on the price entered. on insert, i need to check the new.price and compare it to the prices in PC. Once new.price is less than the price tuple, i set the price to that commission value create or replace TRIGGER findCommission BEFORE INSERT OR UPDATE ON HASLISTING FOR each ROW BEGIN IF (:NEW.ASKING_PRICE < 100001) THEN :NEW.COMMISSION = 6.0; END IF; IF (:NEW.ASKING_PRICE < 250001) THEN :NEW.COMMISSION = 5.5; END IF; IF (:NEW.ASKING_PRICE < 1000001) THEN :NEW.COMMISSION = 5.0; END IF; IF (:NEW.ASKING_PRICE > 1000000) THEN :NEW.COMMISSION = 4.0; END IF; END;

  • float** allocation limit + serialized struct problem. Need advice!

    - by jmgunn
    basically im getting an allocation limit error/warning when i create a float** array. the function i am calling to fill the float** retrieves data from a struct loaded from a file. The function works fine when i use one object but when i load 2 objects into memory i get the limit error. I am pretty sure this is to do with byte alignment or a similar thing because my struct is saved with a float** member which i am sure you are not susposed to do !?! Please confirm this! The next question i have now is how to save/serialize the float** member of this struct? I cant really afford to put an upper bound on the array ie "float [10000][3]" because i need/want to use this structure as a base for many other types of objects that may have well under the upper bound. Stroking my chin here! Any help/advice will recieve my highest gratitude. BTW these said struct objects will be used in a game/graphics package, the float** is a float[3] array for storing vertices in a model. Much thanks in advance

  • How to use JOIN using Hibernate's session.createSQLQuery()

    - by javauser71
    Hi All, I have two Entity (tables) - Employee & Project. An Employee can have multiple Projects. Project table's CREATOR_ID field refers to Employee table's ID field. Employee entity maintains a list of Project. Using EntityManager following query works fine - "entityManager.createQuery("select e from EmployeeDTO e, ProjectDTO p where p.id = ?1 and p.creator.id=e.id"); But since I have the LAZY association relationship, I get error: "Could not initialize proxy - no Session" if I try to access Project info from Employee entity. This is expected and so I am using Hibernate's Session to create query as shown below. Session session = HibernateUtil.getSessionFactory().openSession(); org.hibernate.Query q = session.createSQLQuery("SELECT E FROM EMPLOYEE_TAB E, PROJECT_TAB P WHERE P.ID = " + projectId + " AND P.CREATOR_ID = E.ID") .addEntity("EmployeeDTO ", EmployeeDTO.class) .addEntity("ProjectDTO", ProjectDTO.class); But I get error like: "Column 'E' is either not in any table in the FROM list or appears within a join specification and is outside the scope of the join specification..." Can anyone suggest what will be the right JOIN syntax for such case? If I use ("SELECT * FROM EMPLOYEE_TAB E, ........") - it gives other error: "java.lang.ClassCastException: [Ljava.lang.Object; cannot be cast to com.im.server.dto.EmployeeDTO". Thanks in advance.

  • How to learn a new programming language? And how to choose the appropriate language?

    - by Sebi
    Unfortunately my last question was closed, so I reformulated the question: I know this question was here a lot of times and can't be answered at all, but im not looking for a single name, but rather for an advice in my situation. I learned programming with Java and now I'm developing in Java for more or less 5 years (at the university) and I thinks my programming skills their are really ok/average. I have also small experience in C/C++ and C#. Now I have some spare time and I'd like to learn a new language or deepen the knowledge of Java/C/C++. But how to choose the right language to learn? I'd like to learn a language which will be usefull in the future concerning working in a software development business? I know there is no single answer, but I'm sure you could mention some languages that are more usefull than others. And what's the best way to learn such a language efficiently (bearing in mind that one has already learned some other languages)? Just doing tutorials? Or trying to implement a project? Trying to move a Java project to the new language?
