• Why RenderTarget2D overwrites other objects when trying to put some text in a model?

  - by cad

  I am trying to draw an object composited by two cubes (A & B) (one on top of the other, but for now I have them a little bit more open). I am able to do it and this is the result. (Cube A is the blue and Cube B is the one with brown text that comes from a png texture) But I want to have any text as parameter in the cube B. I have tried what @alecnash suggested in his question, but for some reason when I try to draw cube B, cube A dissapears and everything turns purple. This is my draw code: public void Draw(GraphicsDevice graphicsDevice, SpriteBatch spriteBatch, Matrix viewMatrix, Matrix projectionMatrix) { graphicsDevice.BlendState = BlendState.Opaque; graphicsDevice.DepthStencilState = DepthStencilState.Default; graphicsDevice.RasterizerState = RasterizerState.CullCounterClockwise; graphicsDevice.SamplerStates[0] = SamplerState.LinearClamp; // CUBE A basicEffect.View = viewMatrix; basicEffect.Projection = projectionMatrix; basicEffect.World = Matrix.CreateTranslation(ModelPosition); basicEffect.VertexColorEnabled = true; foreach (EffectPass pass in basicEffect.CurrentTechnique.Passes) { pass.Apply(); drawCUBE_TOP(graphicsDevice); drawCUBE_Floor(graphicsDevice); DrawFullSquareStripesFront(graphicsDevice, _numStrips, Color.Red, Color.Blue, _levelPercentage); DrawFullSquareStripesLeft(graphicsDevice, _numStrips, Color.Red, Color.Blue, _levelPercentage); DrawFullSquareStripesRight(graphicsDevice, _numStrips, Color.Red, Color.Blue, _levelPercentage); DrawFullSquareStripesBack(graphicsDevice, _numStrips, Color.Red, Color.Blue, _levelPercentage); } // CUBE B // Set the World matrix which defines the position of the cube texturedCubeEffect.World = Matrix.CreateTranslation(ModelPosition); // Set the View matrix which defines the camera and what it's looking at texturedCubeEffect.View = viewMatrix; // Set the Projection matrix which defines how we see the scene (Field of view) texturedCubeEffect.Projection = projectionMatrix; // Enable textures on the Cube Effect. this is necessary to texture the model texturedCubeEffect.TextureEnabled = true; Texture2D a = SpriteFontTextToTexture(graphicsDevice, spriteBatch, arialFont, "TEST ", Color.Black, Color.GhostWhite); texturedCubeEffect.Texture = a; //texturedCubeEffect.Texture = cubeTexture; // Enable some pretty lights texturedCubeEffect.EnableDefaultLighting(); // apply the effect and render the cube foreach (EffectPass pass in texturedCubeEffect.CurrentTechnique.Passes) { pass.Apply(); cubeToDraw.RenderToDevice(graphicsDevice); } } private Texture2D SpriteFontTextToTexture(GraphicsDevice graphicsDevice, SpriteBatch spriteBatch, SpriteFont font, string text, Color backgroundColor, Color textColor) { Vector2 Size = font.MeasureString(text); RenderTarget2D renderTarget = new RenderTarget2D(graphicsDevice, (int)Size.X, (int)Size.Y); graphicsDevice.SetRenderTarget(renderTarget); graphicsDevice.Clear(Color.Transparent); spriteBatch.Begin(); //have to redo the ColorTexture //spriteBatch.Draw(ColorTexture.Create(graphicsDevice, 1024, 1024, backgroundColor), Vector2.Zero, Color.White); spriteBatch.DrawString(font, text, Vector2.Zero, textColor); spriteBatch.End(); graphicsDevice.SetRenderTarget(null); return renderTarget; } The way I generate texture with dynamic text is: Texture2D a = SpriteFontTextToTexture(graphicsDevice, spriteBatch, arialFont, "TEST ", Color.Black, Color.GhostWhite); After commenting several parts to see what caused the problem, it seems to be located in this line graphicsDevice.SetRenderTarget(renderTarget);

• How do I locate the CGRect for a substring of text in a UILabel?

  - by bryanjclark

  For a given NSRange, I'd like to find a CGRect in a UILabel that corresponds to the glyphs of that NSRange. For example, I'd like to find the CGRect that contains the word "dog" in the sentence "The quick brown fox jumps over the lazy dog." The trick is, the UILabel has multiple lines, and the text is really attributedText, so it's a bit tough to find the exact position of the string. The method that I'd like to write on my UILabel subclass would look something like this: - (CGRect)rectForSubstringWithRange:(NSRange)range; Details, for those who are interested: My goal with this is to be able to create a new UILabel with the exact appearance and position of the UILabel, that I can then animate. I've got the rest figured out, but it's this step in particular that's holding me back at the moment. What I've done to try and solve the issue so far: I'd hoped that with iOS 7, there'd be a bit of Text Kit that would solve this problem, but most every example I've seen with Text Kit focuses on UITextView and UITextField, rather than UILabel. I've seen another question on Stack Overflow here that promises to solve the problem, but the accepted answer is over two years old, and the code doesn't perform well with attributed text. I'd bet that the right answer to this involves one of the following: Using a standard Text Kit method to solve this problem in a single line of code. I'd bet it would involve NSLayoutManager and textContainerForGlyphAtIndex:effectiveRange Writing a complex method that breaks the UILabel into lines, and finds the rect of a glyph within a line, likely using Core Text methods. My current best bet is to take apart @mattt's excellent TTTAttributedLabel, which has a method that finds a glyph at a point - if I invert that, and find the point for a glyph, that might work. Update: Here's a github gist with the three things I've tried so far to solve this issue: https://gist.github.com/bryanjclark/7036101

• Custumizing Syntax Highlighting in Vim

  - by sixtyfootersdude

  Hey I have defined a few custom file types for vim. I have done this like this: In vimrc: au BufWinEnter,BufRead,BufNewFile *.jak set filetype=jak And then in jak.vim syn match arrows /<-/ syn match arrows /->/ syn match arrows /=>/ syn match arrows /<=/ highlight arrows ctermfg=brown ... This works. (Formatting applies to any file opened with vim with file extension .jak) My question is how I can keep all the current formatting for a file type but add functionality. For example I would like to add this functionality for .vim files: syn keyword yellow yellow highlight yellow ctermfg=yellow ... (so that I can see how my terminal interpenetrates different colors before choosing them.) I have created ~/.vim/syntax/vim.vim (file only contains the above) and put this into my vimrc: au BufWinEnter,BufRead,BufNewFile *.vim set filetype=vim This has no effect. The word yellow is not colored yellow. I have also tried putting my vim.vim file into ~/.vim/after/syntax/vim.vim As suggested here This is the approach that I would like to take. Seems clean and easily maintainable.

• Gallio MbUnit and Team City problem

  - by Bernard Larouche

  I asked a question this morning about an integration problem between Gallio and Team City. I changed the msbuild file to use the proper syntax with the latest Gallio build script API.

It divide "x" inside the loop. For example in JS: <li class="jcarousel-item jcarousel-item-horizontal jcarousel-item-'+[x]+' jcarousel-item-'+[x]+'-horizontal jcarousel-item-placeholder jcarousel-item-placeholder-horizontal"> And HTML out is: <li class="jcarousel-item jcarousel-item-horizontal jcarousel-item-0 jcarousel-item-0-horizontal jcarousel-item-placeholder jcarousel-item-placeholder-horizontal"></li> then <li class="jcarousel-item jcarousel-item-horizontal jcarousel-item-3 jcarousel-item-3-horizontal jcarousel-item-placeholder jcarousel-item-placeholder-horizontal"></li> then <li class="jcarousel-item jcarousel-item-horizontal jcarousel-item-6 jcarousel-item-6-horizontal jcarousel-item-placeholder jcarousel-item-placeholder-horizontal"></li> etc... What I need is that count goes as 0-1-2-3-4-5-etc, but with divide it goes 0-3-6-etc and jCarousel insert blank li's 1-2, 4-5, 7-8. How I can avoid "x" divide inside the loop? Tnak you!

• ASP.Net MVC 3 Full Name In DropDownList

  - by tgriffiths

  I am getting a bit confused with this and need a little help please. I am developing a ASP.Net MVC 3 Web application using Entity Framework 4.1. I have a DropDownList on one of my Razor Views, and I wish to display a list of Full Names, for example Tom Jones Michael Jackson James Brown In my Controller I retrieve a List of User Objects, then select the FirstName and LastName of each User, and pass the data to a SelectList. List<User> Requesters = _userService.GetAllUsersByTypeIDOrgID(46, user.organisationID.Value).ToList(); var RequesterNames = from r in Requesters let person = new { UserID = r.userID, FullName = new { r.firstName, r.lastName } } orderby person.FullName ascending select person; viewModel.RequestersList = new SelectList(RequesterNames, "UserID", "FullName"); return View(viewModel); In my Razor View I have the following @Html.DropDownListFor(model => model.requesterID, Model.RequestersList, "Select", new { @class = "inpt_a"}) @Html.ValidationMessageFor(model => model.requesterID) However, when I run the code I get the following error At least one object must implement IComparable. I feel as if I am going about this the wrong way, so could someone please help with this? Thanks.

• Regex with optional part doesn't create backreference

  - by padraigf

  I want to match an optional tag at the end of a line of text. Example input text: The quick brown fox jumps over the lazy dog {tag} I want to match the part in curly-braces and create a back-reference to it. My regex looks like this: ^.*(\{\w+\})? (somewhat simplified, I'm also matching parts before the tag): It matches the lines ok (with and without the tag) but doesn't create a back-reference to the tag. If I remove the '?' character, so regex is: ^.*(\{\w+\}) It creates a back-reference to the tag but then doesn't match lines without the tag. I understood from http://www.regular-expressions.info/refadv.html that the optional operator wouldn't affect the backreference: Round brackets group the regex between them. They capture the text matched by the regex inside them that can be reused in a backreference, and they allow you to apply regex operators to the entire grouped regex. but must've misunderstood something. How do I make the tag part optional and create a back-reference when it exists?

• Filter entities that match all pairs

  - by Jon

  I have an entity (let's say Person) with a set of arbitrary attributes with a known subset of values. I need to search for all of these entities that match all my filter conditions. For example, my table structures look like this: Person: id | name 1 | John Doe 2 | Jane Roe 3 | John Smith Attribute: id | attr_name 1 | Sex 2 | Eye Color ValidValue: id | attr_id | value_name 1 | 1 | Male 2 | 1 | Female 3 | 2 | Blue 4 | 2 | Green 5 | 2 | Brown PersonAttributes id | person_id | attr_id | value_id 1 | 1 | 1 | 1 2 | 1 | 2 | 3 3 | 2 | 1 | 2 4 | 2 | 2 | 4 5 | 3 | 1 | 1 6 | 3 | 2 | 4 In JPA, I have entities built for all of these tables. What I'd like to do is perform a search for all entities matching a given set of attribute-value pairs. For instance, I'd like to be able to find all males (John Doe and John Smith), all people with green eyes (Jane Roe or John Smith), or all females with green eyes (Jane Roe). I see that I can already take advantage of the fact that I only really need to match on value_id, since that's already unique and tied to the attr_id. But where can I go from there?

• Efficient alternative to merge() when building dataframe from json files with R?

  - by Bryan

  I have written the following code which works, but is painfully slow once I start executing it over thousands of records: require("RJSONIO") people_data <- data.frame(person_id=numeric(0)) json_data <- fromJSON(json_file) n_people <- length(json_data) for(lender in 1:n_people) { person_dataframe <- as.data.frame(t(unlist(json_data[[person]]))) people_data <- merge(people_data, person_dataframe, all=TRUE) } output_file <- paste("people_data",".csv") write.csv(people_data, file=output_file) I am attempting to build a unified data table from a series of json-formated files. The fromJSON() function reads in the data as lists of lists. Each element of the list is a person, which then contains a list of the attributes for that person. For example: [[1]] person_id name gender hair_color [[2]] person_id name location gender height [[...]] structure(list(person_id = "Amy123", name = "Amy", gender = "F", hair_color = "brown"), .Names = c("person_id", "name", "gender", "hair_color")) structure(list(person_id = "matt53", name = "Matt", location = structure(c(47231, "IN"), .Names = c("zip_code", "state")), gender = "M", height = 172), .Names = c("person_id", "name", "location", "gender", "height")) The end result of the code above is matrix where the columns are every person-attribute that appears in the structure above, and the rows are the relevant values for each person. As you can see though, some data is missing for some of the people, so I need to ensure those show up as NA and make sure things end up in the right columns. Further, location itself is a vector with two components: state and zip_code, meaning it needs to be flattened to location.state and location.zip_code before it can be merged with another person record; this is what I use unlist() for. I then keep the running master table in people_data. The above code works, but do you know of a more efficient way to accomplish what I'm trying to do? It appears the merge() is slowing this to a crawl... I have hundreds of files with hundreds of people in each file. Thanks! Bryan

• Django's post_save signal behaves weirdly with models using multi-table inheritance

  - by hekevintran

  Django's post_save signal behaves weirdly with models using multi-table inheritance I am noticing an odd behavior in the way Django's post_save signal works when using a model that has multi-table inheritance. I have these two models: class Animal(models.Model): category = models.CharField(max_length=20) class Dog(Animal): color = models.CharField(max_length=10) I have a post save callback called echo_category: def echo_category(sender, **kwargs): print "category: '%s'" % kwargs['instance'].category post_save.connect(echo_category, sender=Dog) I have this fixture: [ { "pk": 1, "model": "animal.animal", "fields": { "category": "omnivore" } }, { "pk": 1, "model": "animal.dog", "fields": { "color": "brown" } } ] In every part of the program except for in the post_save callback the following is true: from animal.models import Dog Dog.objects.get(pk=1).category == u'omnivore' # True When I run syncdb and the fixture is installed, the echo_category function is run. The output from syncdb is: $ python manage.py syncdb --noinput Installing json fixture 'initial_data' from '~/my_proj/animal/fixtures'. category: '' Installed 2 object(s) from 1 fixture(s) The weird thing here is that the dog object's category attribute is an empty string. Why is it not 'omnivore' like it is everywhere else? As a temporary (hopefully) workaround I reload the object from the database in the post_save callback: def echo_category(sender, **kwargs): instance = kwargs['instance'] instance = sender.objects.get(pk=instance.pk) print "category: '%s'" % instance.category post_save.connect(echo_category, sender=Dog) This works but it is not something I like because I must remember to do it when the model inherits from another model and it must hit the database again. The other weird thing is that I must do instance.pk to get the primary key. The normal 'id' attribute does not work (I cannot use instance.id). I do not know why this is. Maybe this is related to the reason why the category attribute is not doing the right thing?

  I have the following; <% using(Html.BeginForm("GetRecommendedProducts", "Home", FormMethod.Post)) { %> <% Html.RenderPartial("QuickQuote", Model.quickQuote); %> <div class="But brown" style="float:left;"> <a href="." onclick="$.unblockUI(); return false;">Close</a> </div> <div class="But green" style=""> <a href="." onclick="this.form.submit(); return false;">Go</a> </div> <%} %> When I click the anchor I do not get a post to my action. I know this should be possible so what am I doing wrong? The partial view only contains fields and not another BeginForm or anything like that. If I use a submit button it works ok but I can't use a submit button I need to use an anchor.

• Mysterious extra hashtable entry

  - by Harm De Weirdt

  Good evening everyone, I'm back :) Let me explain my problem. I have a hashtable in wich I store the products a costumors buys (%orders). It uses the productcode as key and has a reference to an array with the other info as value. At the end of the program, I have to rewrite the inventory to the updated version (i.e. subtract the quantity of the bought items) This is how I do this: sub rewriteInventory{ open(FILE,'>inv.txt'); foreach $key(%inventory){ print FILE "$key\|$inventory{$key}[0]\|$inventory{$key}[1]\|$inventory{$key}[2]\n" } close(FILE); } where $inventory{$key}[x] is 0 - Title, 1 - price, 2 - quantity. The problem here is that when I look at inv.txt afterwards, I see things like this: CD-911|Lady Gaga - The Fame|15.99|21 ARRAY(0x145030c)||| BOOK-1453|The Da Vinci Code - Dan Brown|14.75|12 ARRAY(0x145bee4)||| Where do these "ARRAY(0x145030c)|||" entries come from? Or more important, how do I get rid of them? This is the last part of this school task, I had so much problems programming all this and this stupid little thing comes up now and I'm really fed up with this whole Perl thing. (this aside :p) I hope someone can help me :) Fuji

• Match entities fulfilling filter (strict superset of search)

  - by Jon

  I have an entity (let's say Person) with a set of arbitrary attributes with a known subset of values. I need to search for all of these entities that match all my filter conditions. That is, given a set of Attributes A, I need to find all people that have a set of Attributes that are a superset of A. For example, my table structures look like this: Person: id | name 1 | John Doe 2 | Jane Roe 3 | John Smith Attribute: id | attr_name 1 | Sex 2 | Eye Color ValidValue: id | attr_id | value_name 1 | 1 | Male 2 | 1 | Female 3 | 2 | Blue 4 | 2 | Green 5 | 2 | Brown PersonAttributes id | person_id | attr_id | value_id 1 | 1 | 1 | 1 2 | 1 | 2 | 3 3 | 2 | 1 | 2 4 | 2 | 2 | 4 5 | 3 | 1 | 1 6 | 3 | 2 | 4 In JPA, I have entities built for all of these tables. What I'd like to do is perform a search for all entities matching a given set of attribute-value pairs. For instance, I'd like to be able to find all males (John Doe and John Smith), all people with green eyes (Jane Roe or John Smith), or all females with green eyes (Jane Roe). I see that I can already take advantage of the fact that I only really need to match on value_id, since that's already unique and tied to the attr_id. But where can I go from there? I've been trying to do something like the following, given that the ValidValue is unique in all cases: select distinct p from Person p join p.personAttributes a where a.value IN (:values) Then I've tried putting my set of required values in as "values", but that gives me errors no matter how I try to structure that. I also have to get a little more complicated, as follows, but at this point I'd be happy with solving the first problem cleanly. However, if it's possible, the Attribute table actually has a field for default value: id | attr_name | default_value 1 | Sex | 1 2 | Eye Color | 5 If the value you're searching on happens to be the default value, I want it to return any people that have no explicit value set for that attribute, because in the application logic, that means they inherit the default value. Again, I'm more concerned about the primary question, but if someone who can help with that also has some idea of how to do this one, I'd be extremely grateful.

• Confused about Ajax, Basic XMLHTTPRequest

  - by George

  I'm confused about the basics of Ajax. Right now I'm just trying to build a basic Ajax request using plain JavaScript to better understand how things work (as opposed to using Jquery or another library). First off, do you always need to pass a parameter or can you just retrieve data? In its most basic form, could I have an html document (located on the same server) that just has plain text, and another html document retrieve that text and load it on to the page? So I have fox.html with just text that says "The quick brown fox jumped over the lazy dog." and I want to pull in that text into ajax.html on load. I have the following on ajax.html <script type="text/javascript"> function createAJAX() { var ajax = new XMLHttpRequest(); ajax.open('get','fox.html',true); ajax.send(null); ajax = ajax.responseText; return(ajax); } document.write(createAJAX()); </script> This currently writes nothing when I load the page.

• Excel CSV into Nested Dictionary; List Comprehensions

  - by victorhooi

  heya, I have a Excel CSV files with employee records in them. Something like this: mail,first_name,surname,employee_id,manager_id,telephone_number [email protected],john,smith,503422,503423,+65(2)3423-2433 [email protected],george,brown,503097,503098,+65(2)3423-9782 .... I'm using DictReader to put this into a nested dictionary: import csv gd_extract = csv.DictReader(open('filename 20100331 original.csv'), dialect='excel') employees = dict([(row['employee_id'], row) for row in gp_extract]) Is the above the proper way to do it - it does work, but is it the Right Way? Something more efficient? Also, the funny thing is, in IDLE, if I try to print out "employees" at the shell, it seems to cause IDLE to crash (there's approximately 1051 rows). 2. Remove employee_id from inner dict The second issue issue, I'm putting it into a dictionary indexed by employee_id, with the value as a nested dictionary of all the values - however, employee_id is also a key:value inside the nested dictionary, which is a bit redundant? Is there any way to exclude it from the inner dictionary? 3. Manipulate data in comprehension Thirdly, we need do some manipulations to the imported data - for example, all the phone numbers are in the wrong format, so we need to do some regex there. Also, we need to convert manager_id to an actual manager's name, and their email address. Most managers are in the same file, while others are in an external_contractors CSV, which is similar but not quite the same format - I can import that to a separate dict though. Are these two items things that can be done within the single list comprehension, or should I use a for loop? Or does multiple comprehensions work? (sample code would be really awesome here). Or is there a smarter way in Python do it? Cheers, Victor

• response.Text is undefined when returning variable

  - by George

  Not sure if the problem is related to Ajax or something silly about JavaScript that I'm overlooking in general, but I have the following script where fox.html is just plain text that reads, "The quick brown fox jumped over the lazy dog." : function loadXMLDoc() { if (window.XMLHttpRequest) {// code for IE7+, Firefox, Chrome, Opera, Safari xmlhttp=new XMLHttpRequest(); } else {// code for IE6, IE5 xmlhttp=new ActiveXObject("Microsoft.XMLHTTP"); } xmlhttp.open("GET","fox.html",true); xmlhttp.send(); xmlhttp.onreadystatechange=function() { if (xmlhttp.readyState==4 && xmlhttp.status==200) { fox = xmlhttp.responseText; alert(fox); } } } onload = loadXMLDoc; The above script alerts the contents of fox.html onload just fine. However if I change the script so that: { fox = xmlhttp.responseText; alert(fox); } becomes: { fox = xmlhttp.responseText; return fox; } and alert(loadXMLDoc()); onload I get 'undefined'. I'm wondering why this is so.

• Pronunciation of programming structures (particularly in c#)

  - by Andrzej Nosal

  As a non-English speaking person I often have problems pronouncing certain programming structures and abbreviations. I've been watching some video tutorials and listening to podcasts as well, though I couldn't catch them all. My question is what is the common or correct pronunciation of the following code snippets? Generics, like IEnumerable<int> or in a method void Swap<T>(T lhs, T rhs) Collections indexing and indexer access e.g. garage[i], rectangular arrays myArray[2,1] or jagged[1][2][3] Lambda operator =>, e.g. in a where extension method .Where(animal => animal.Color == Color.Brown) or in an anonymous method () => { return false;} Inheritance class Derived : Base (extends?) class SomeClass : IDisposable (implements?) Arithemtic operators += -= *= /= %= ! Are += and -= pronounced the same for events? Collections initializers new int[] { 4, 5, 8, 9, 12, 13, 16, 17 }; Casting MyEnum foo = (MyEnum)(int)yourFloat; (as?) Nullables DateTime? dt = new DateTime?(); I tagged the question with C# as some of them are specific to C# only.

• Mac vs. Windows Browser Font Height Rendering Issue

  - by cdmckay

  I'm using a custom font and the @font-face tag. In Windows, everything looks great, regardless of whether it's Firefox, Chrome, or IE. On Mac, it's a different story. For some reason, the Mac font renderer thinks the font is a lot shorter than it is. For example, consider this test code (live example here): <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8" /> <title>Webble</title> <style type="text/css"> @font-face { font-family: "Bubbleboy 2"; src: url("bubbleboy-2.ttf") format('truetype'); } body { font-family: "Bubbleboy 2"; font-size: 30px; } div { background-color: maroon; color: yellow; height: 100px; line-height: 100px; } </style> </head> <body> <div>The quick brown fox jumped over the lazy dog.</div> </body> </html> Open it on Windows Firefox and on Mac Firefox. Use your mouse to select it. On Windows, you'll notice it fully selects the font. On Mac, it only selects about half the font. If you look at what it is selecting, you'll see that that part has been centered, instead of the full height of the font. Is there anyway to fix this rather large discrepancy?

• For each <item> in CheckedListBox. <item> returns as Object and not as Control

  - by Tivie

  Hello there. I have a CheckedListBox previously populated. I want to loop with a "for each / next" through all items in the CheckedListBox and do a lot of "stuff" with each iteration element of the checkedlistbox. example code: For Each item In CheckedListBox1.Items If item.Checked = True Then 'do stuff like item.BackColor = Color.Blue Else 'do other stuff item.BackColor = Color.Brown End If Next the problem is that is an 'Object' type and not a 'Control' type. If I force the iteration var As CheckBox, it throws an InvalidCastException saying that type 'System.String' can't be associated with type 'System.Windows.Forms.CheckBox' I know I can easily work around using for i=0 to CheckedListBox.Items.Count - 1 but I want to use a for each /next loop since I have a lot of code in that loop (and With can't be used) and always poiting directly to the object is something I wish to avoid and I really need the code to be as simple as possible. I actually spent one afternoon looking for this but couldn't find any answer. If someone could be kind enough to enlight me in this, it would be extremely appreciated. Best regards

• JavaFx 2.1, 2.2 TableView update issue

  - by Lewis Liu

  My application uses JPA read data into TableView then modify and display them. The table refreshed modified record under JavaFx 2.0.3. Under JavaFx 2.1, 2.2, the table wouldn't refresh the update anymore. I found other people have similar issue. My plan was to continue using 2.0.3 until someone fixes the issue under 2.1 and 2.2. Now I know it is not a bug and wouldn't be fixed. Well, I don't know how to deal with this. Following are codes are modified from sample demo to show the issue. If I add a new record or delete a old record from table, table refreshes fine. If I modify a record, the table wouldn't refreshes the change until a add, delete or sort action is taken. If I remove the modified record and add it again, table refreshes. But the modified record is put at button of table. Well, if I remove the modified record, add the same record then move the record to the original spot, the table wouldn't refresh anymore.

• Creating a json array and json items with jquery?

  - by user246114

  Hi, I made a simple javascript class like this: function Horse() { this.color = 'brown'; this.speed = 'somewhat slow'; } I attached a few instances to some elements, like this: $("#horse1").data('d', new Horse()); $("#horse2").data('d', new Horse()); $("#horse3").data('d', new Horse()); now I want to create a JSON array with a JSON representation of each horse object. So I'm doing this: // How do I create an empty JSON array here?: var myJsonArray = ?; var children = $("#horses").children(); for (var i = 0, m = children.size(); i < m; i++) { var panel = children[i]; var horse = $(panel).data('h'); // And how do I create a JSON rep of my horse here? var myJsonHorse = new JsonHorse(?); // Finally, how do I add it to the json array? myJsonArray.push(myJsonHorse); } yeah my end goal is to have a single json array of all the horses after iterating over all the children - not sure if this should be done in plain javascript or in jquery? Thanks

• Really cool way to create custom UITabBar for iPhone app?

  - by ludicco

  Hi, I am doing a lot of researching lately about how to get a different looking with nice effects UITabBar on my iPhone app, but unfortunately I am only finding things on how to replace background color etc. Well, I've checked out this app called Momento which is pretty cool and presents a very slick tabBar: So there are a couple of elements here I would like to ask you guys if you could help me by giving me the right directions on how to get a similar effect :) Arrow above items: as you can see this app has this animated arrow that runs above the selected item with a very smooth animation. Selected Stated of the item's image is not that blue-ish default one neither the default state which displays in a different shade of brown and gray version. nice Items separators with beveled vertical lines. diferrent background image for the tabBar different height for the tabBar At this point after some research I am able to set the height and background image by subclassing UITabBarController but I'm still not sure on how to accomplish the other items specially the first one related to the nice arrow effect. If someone knows about a very good tutorial on how to do this it would be great for clarifying what can or can't be done by subclassing the UITabBarController and specially if can be done in Interface Builder :) I am just starting on this world off app development for iOS so if you could help me on that it would be really appreciated Thanks a lot in advance
