• Change Titlewindow close button

  - by Cameigons

  I'm working with Flex 3.4 SDK. I need to change the default close button image from a TitleWindow. So what I'm doing is defining a CSS selector, like this: TitleWindow{ close-button-skin: Embed('assets/close.png'); border-color: #FFFFFF; corner-radius: 10; closeButtonDisabledSkin: ClassReference(null); closeButtonDownSkin: ClassReference(null); closeButtonOverSkin: ClassReference(null); closeButtonUpSkin: ClassReference(null); } The problem is: the result image is totally squeezed beyond recognition. Probably because the image dimensions are 55x10 pixels (much wider than the default closebutton square-like dimensions) and flex forces it to fit that size. Would anyone know how to go about fixing that?

• UIScrollView content to track a CAKeyFrameAnimation along a path

  - by CMLloyd

  In my App I have a full-screen UIScrollView where the content is a UIImageView containing a map image which is about 2000px square (i.e. larger than the UIScrollView). Currently, I plot a path across the map and animate a "beacon" image along it using a CAKeyFrameAnimation, which works great. What I would like to be able to do is to make the UIScrollView content move with the animation in such a way as to keep the beacon image in the centre of the screen (giving the user the impression of tracking along the path). Any suggestions on how I might achieve this?

• Caching generated QR Code

  - by Michal K

  I use zxing to encode a qr code and store it as a bitmap and then show it in ImageView. Since the image generation time is significant I'm planning to move it to a separate thread (AsyncTaskLoader will be fine I think). The problem is - it's an image and I know that to avoid memory leaks one should never store a strong reference to it in an Activity. So how would you do it? How to cache an image to survive config changes (phone rotation) and generally avoid generating it onCreate()? Just point me in the right direction, please.

• Resizing JPopupMenu and avoiding a "flicker" issue

  - by Avrom

  Hi, I am trying to implement a search results popup list similar to the style found here: http://www.inquisitorx.com/ (I'm not trying to implement a Google search, I'm just using this as a rough example of the style I'm working on.) In any event, I am implementing this by using a JList contained within a JPopupMenu which is popped up underneath a JTextField. When a user enters search terms, the list changes to reflect different matching results. I then call pack on the JPopupMenu to resize it. This works, however, it creates a slight flicker effect since it is actually hiding the popup and showing a popup. (See the private method getPopup in JPopupMenu where it explicitly does this.) Is there any way to just get it to just resize itself (aside from using a JWindow)?

• print css: fit in one page

  - by user281521

  Hi. In my page there's only one image. Kind of 1500x3000 px. In the printer, I need that this image's maximum width to be the width of the page, so I did: width 100% in the css, and it works. But the height... the old bullshit of height 100% will never work. Because it always will be 100% of the parent container, then someone must have height defined. Or html or body. So, my question is: make this image fit in one page. Any ideas?

• How do I add a textbox to my other jQuery click function?

  - by marcamillion

  Right now, my script adds a box to the cursor when I click on an image, as can be seen in the following code. Please note, this is jQuery. $(function() { var tag_box = $("<div>").appendTo("body").css({"width":"40px", "height":"40px", "border":"4px solid #000000", "position":"absolute", "display":"none", "padding":"15px"}); $("#image-wrapper").live('click', function(e){ tag_box.css({"left": e.pageX - 40, "top": e.pageY - 40, "display":"block"}); }); I would like to add a text field to appear right below that tag_box on that same click. I tried to do this, but it hasn't worked out like I thought it would: var comment_box = $("<label> Comment: <input type='text' name='comment' autocomplete='off'></label>"); $("#image-wrapper").live('click', function(){ $("body").append(comment_box); }); Any assistance you can give me, would be greatly appreciated. Thanks.

• javascript ajax variable question..

  - by Kelso

  Hey there, new to AJAX, JS.. Im trying to add to a Javascript/Ajax search script that I've put together. Previously, it had a single search field, called search_word, I added one called search_date. $(".search_button").click(function() { var search_word = $("#search_box").val(); var search_date = $("#datepicker").val(); var dataString = 'search_word='+ search_word; if(search_word=='') { } else { $.ajax({ type: "GET", url: "searchdata.php", data: dataString, In the Ajax, it appears to pass data of dataString, to my processing script. How do I add search date to the dataString so that I can use that var in my searchdata.php? In searchdata, I can do this $search_word=$_GET['search_word']; and use that var, but so far every time i attempt to alter the dataString, it breaks all the other functionality. Thanks!

• iphone memory leaks and malloc?

  - by Brodie4598

  Okay so im finally to the point where I am testing my iPad App on an actual iPad... One thing that my app does is display a large (2mb) image in a scroll view. This is causing the iPad to get memory warnings. I run the app in the instruments to check for the leak. When I load the image, a leak is detected and i see the following in the allocations: ALl Allocations: 83.9 MB Malloc 48.55 MB: 48.55 MB Malloc 34.63 MB: 34.63 MB What im trying to understand is how to plug the leak obviously, but also why a 2MB image is causing a malloc of 20x that size I am very new to programming in obj-c so im sure this is an obvious thing, but I just cant figure it out. Here is the code:

• Drupal Imagecache not working

  - by stef

  I created an Imagecache setting that just resizes to 125px wide. First issue is that the preview image is 404. Then I want to print out an image via <?php print theme('imagecache', 'imported_image', $node->picture, 'test', 'test', $attributes); ?> 'imported_image' being the preset and $node-picture is a correct path. The html prints out ok but the path it's trying load the image from does not exist. In sites/default/files/imagecache there is no folder with the name of the preset. Flushing the preset does nothing. The imagecache folder is writeable by everyone. This is on MAMP. Anyone know what the issue could be?

• How can I subsample data from a time series with LINQ to SQL?

  - by Chris Farmer

  I have a database table full of time points and experimental values at those time points. I need to retrieve the values for an experiment and create a thumbnail image showing an XY plot of its data. Because the actual data set for each experiment is potentially 100,000 data points and my image is only 100 pixels wide, I want to sample the data before creating the image. My current query (which retrieves all the data without sampling) is something simple like this: var points = from p in db.DataPoints where p.ExperimentId == myExperimentId orderby p.Time select new { X = p.Time, Y = p.Value } So, how can I best take every nth point from my result set in a LINQ to SQL query?

• Chain LINQ IQueryable, and end with Stored Procedure

  - by Alex

  I'm chaining search criteria in my application through IQueryable extension methods, e.g.: public static IQueryable<Fish> AtAge (this IQueryable<Fish> fish, Int32 age) { return fish.Where(f => f.Age == age); } However, I also have a full text search stored procedure: CREATE PROCEDURE [dbo].[Fishes_FullTextSearch] @searchtext nvarchar(4000), @limitcount int AS SELECT Fishes.* FROM Fishes INNER JOIN CONTAINSTABLE(Fishes, *, @searchtext, @limitcount) AS KEY_TBL ON Fishes.Id = KEY_TBL.[KEY] ORDER BY KEY_TBL.[Rank] The stored procedure obviously doesn't return IQueryable, however, is it possible to somehow limit the result set for the stored procedure using IQueryable's? I'm envisioning something like .AtAge(5).AboveWeight(100).Fishes_FulltextSearch("abc"). In this case, the fulltext search should execute on a smaller subset of my Fishes table (narrowed by Age and Weight). Is something like this possible? Sample code?

• Coordinates in distorted grid

  - by Carsten

  I have a grid in a 2D system like the one in the before image where all points A,B,C,D,A',B',C',D' are given (meaning I know the respective x- and y-coordinates). I need to calculate the x- and y-coordinates of A(new), B(new), C(new) and D(new) when the grid is distorted (so that A' is moved to A'(new), B' is moved to B'(new), C' is moved to C'(new) and D' is moved to D'(new)). The distortion happens in a way in which the lines of the grid are each divided into sub-lines of equal length (meaning for example that AB is divided into 5 parts of the equal length |AB|/5 and A(new)B(new) is divided into 5 parts of the equal length |A(new)B(new)|/5). The distortion is done with the DistortImage class of the Sandy 3D Flash engine. (My practical task is to distort an image using this class where the handles are not positioned at the corners of the image like in this demo but somewhere within it).

• Re-factoring a CURL request to Ruby's RestClient

  I'm having trouble translating this CURL request into Ruby using RestClient: system("curl --digest -u #{@user}:#{@pass} '#{@endpoint}/#{id}' --form image_file=@'#{path}' -X PUT") I keep getting 400 Bad Request errors. As far as I can tell, the request does get properly authenticated, but hangs up from the file upload part.

• JLabel withing another JLabel

  - by out_sider

  I want to do a very simple thing with java swing and I'm not being able to. I added a jLabel as it is the only object using java swing that can hold an image (using the icon property)...at least I wasn't able to set an image using other objects. Now I want to add another jlabel in top of the first one with another image so it can be "clicked" independently from the "background" label. But whenever I try to add it using the graphical editor or by doing jLabel1.add(jLabel2) it doesn't work...it simply sets next to the label1 but not on top of it. This is in order to do a java application like the Tic Tac Toe game...so I can have the background which are squares (first label) and the others the "X" and "O". board This might be the board and I want to put labels on each square so they can be the pieces.

• Help needed with MySQL query to join data spanning multiple tables with data used as column names

  - by gurun8

  I need a little help putting together a SQL query that will give me the following resultsets: and The data model looks like this: The tricky part for me is that the columns to the right of the "Product" in the resultset aren't really columns in the database but rather key/value pairs spanned across the data model. Table data is as follows: My apologies in advance for the image heavy question and the image quality. This just seemed like the easiest way to convey the information. It'll probably take someone less time to write the query statement to achieve the results than it did for me to assemble this question. By the way, the "product_option" table image is truncated but it illustrated the general idea of the data structure. The MySQL server version is 5.1.45.
