• Using jquery scrollTop to position absolute Div

  - by Tim

  Hello, I am trying to position an Absolute DIV using Jquery, depending on where the user is clicking on the page. At the moment this works just great $('#window').css('left', jsEvent.pageX); $('#window').css('top', jsEvent.pageY); This positions the element exactly where my mouse has clicked the screen... Until you scroll down that is. That is why I am trying to achieve something that will take the amount of pixels from the top of the page into account. I thought something like this... $('#window').css('top', jsEvent.pageY + scrollTop()); would do the trick, unfortunately it doesn't work. Any hints? Thanks, Tim

• Can't get access to PHPmyAdmin after setting a root password and using Instant Rails

  - by Derek

  Wanted to get started with Ruby on Rails so I installed instant rails and set up a mysql password. Problem is now I can't get access to phpmyadmin. From the rails control panel, when I go to configure database (via PhpMyadmin) it opens up phpmyadmin with the message Error MySQL said: Documentation #1045 - Access denied for user 'root'@'localhost' (using password: NO) When I used to use XAMPP after setting a password instead of taking me directly within phpmyadmin (as it did without a password) it took me to the login screen instead. With instant rails that's not the case. Anyone had this problem when they first set a mysql password and using the instant rails package?

• Oracle SQLPlus: How to display the output of a sqlplus command without having to first issue the spo

  - by ziggy

  Is there a way to display the output of a sqlplus command without having to first issue the spool off command? I am spooling the results of a sqlplus session to a file while at the same time tailing the file. The reason for this is that for table with very long rows the format is easier to look at from a file. The problem is to see the output i have to issue the spool off command everytime i run a command in sqlplus. Can i configure sqlplus so that after i have issued the spool command all the output is viewable straight away on the file. (Formating the way the rows are displayed on the screen is not an option. ) THanks

• Updating GUI axes in MATLAB

  - by James

  HI, I am making a GUI for a program I have created, where I need to be able to change the position of a load along a beam. I have set up the axes and the slider properly, but I am unsure how to get the axes to update, as I can't find any examples that show how to do this on the internet. At present, as I move the load, the position updates properly, but the old position stays on screen as well, which is quite annoying. Can anyone recommend any good examples that show how to do this, or does anyone have a suggestion of how to go about refreshing the axes? Regards, James

• Location of New Window after old window closed

  - by John Brayton

  I have an app that allows multiple windows. I have a strange bug where, if I repeatedly open and close windows, new windows are positioned lower and lower on the screen. I would expect this if I were keeping the windows open, but it seems that the OS X window tiling mechanism is unaware of when my windows are closing. Potentially relevant notes: I am using garbage collection. This is not a document-based app. When I close a window, the corresponding menu item is removed from the "Window" menu. Any hints as to what I might be doing wrong would be appreciated. Thanks!

• How do I set up mod rewrite to do this?

  - by Ali

  Hi guys heres the scene - I'm building a web application which basically creates accounts for all users. Currently its setup like this the file structure: root/index.php root/someotherfile.php root/images/image-sub-folder/image.jpg root/js/somejs.js When users create an account they choose a fixed group name and then users can join that group. Initially I thought of having an extra textbox in the login screen to enter the group the user belongs to login to. BUt I would like instead to have something like virtual folders in this case: root/group-name/index.php I heard it can be done with apache mod rewrite but I'm not sure how to do this - any help here? Basically instead of having something like &group-name=yourGroupName appended to every page I would just like something of the nature above.

• UILabel background color not updating in UITableView

  - by Joey

  I'm having a perplexing problem with a simple UILabel I put on a cell in a UITableView. I enter a separate view after tapping on a row, like many UITableViews. In there, I update the cell so that when I return to the rows, it should be updated, with this: MyTableViewCell* cell = (MyTableViewCell*) [mTableView cellForRowAtIndexPath: [NSIndexPath indexPathForRow:mActiveRow inSection:0]]; cell.myLabel.text = @"New Value"; // updated text cell.myLabel.backgroundColor = [UIColor greenColor]; // updated color When I return, though, only the text is updated, not the color. When I scroll the row off the screen and return it refreshes properly via another path of code that has exactly the same code. Could there be some trigger to refresh specifically the background color of the UILabel? I'm not sure why the text will refresh but the color won't.

• How to store user preferences? Cookie becomes bigger..

  - by ari

  My application (Asp.Net MVC) has great interaction with the user interface (jQuery/js). For example, setting various searches charts, moving the gadgets on the screen and more .. I of course want to keep all data for each user. So that data will be available from any page in the Dumaine and the user will accepts his preferences. Now I keep all data in a cookie because it did not seem logical asynchronous access to the server each time the user changes something and thet happens a lot.When the user logout from the application I save the cookie to the database. The problem is the cookie becomes very large. The thought that this huge cookie is attached to each server request makes me feel that my attitude is wrong. Another problem cookies have size limit. It varies from your browser but I definitely have been close to the border - my cookie easily become 4kb Is there another solution?

• VS2010 method comment block pretty format.

  - by camelCase

  I have just installed the lastest RC of VS2010, which for me represents a shift from VS2008. A new comment formatting feature that I was looking forward to appears to be missing. About 6 months ago I read a Scott Gu blog post that mentioned a new VS2010 feature that would format /// style method comment blocks into more readable formatted regions inline with other code. The Scott Gu blog did not provide a screen shot but I was expecting the VS2010 editor to remove the XML tags from the /// method comment block and render just the essential text comment. Was this feature pulled during the Beta, or is there an option switch urking somewhere?

• Generated Word 2007 prints scrunched up

  - by Brad

  Our website generates Word 2007 documents from database data by creating the xml, zipping it and sending it as a MIME attachment. Usually, this works fine. On occasion, the document will look fine on the screen, but not when printed. The letters end up scrunched together. Here is an example. This is a 1 page document, the first page is a scan of the document printed correctly, the 2nd page is a scan of the same document printed with the problem. Here is the original document. Has anyone ever seen anything similar? I cannot figure out if this is a bug in the code that generates our XML, a bug in the printer driver or a bug in Word. Any ideas would be greatly appreciated. Please note that this document does not contain any real data other than public information, but disregard the contents - this is not an official document, and only meant to illustrate our problem.

• iPad/iPod: autoRotate resizes view in window

  - by Jasconius

  Developing an iPad interface, I have a scenario where I have a UIViewController which manages a view that gets placed directly as a subview of the main UIWindow. Before being placed in the UIWindow, that view gets resized to a non-standard size, let's say, 768x460, and positioned at the bottom of the screen. When rotating the device, the autoRotate feature of the UIViewController causes the view to be resized so that it fills the entire UIWindow space. I thought this might be because in the XIB, the view is set to window size, but when I changed it to reflect the desired size, it still expanded it to the window size. Then I went into the MainWindow XIB and turned off autoresizeSubviews, and it still happens. This is a very frustrating problem, I am hoping that there is merely something obvious that I am missing out on. Anyone have any bright ideas?

• Is is possible to derive currency symbol from currency code?

  - by Dave Hunt

  My iPhone app formats an NSDecimalNumber as a currency using setCurrencyCode, however another screen displays just the currency symbol. Rather than storing both the currency code and symbol, is it possible to derive the symbol from the code? I thought the following might work, but it just returns the symbol as $: currencyCode = [dictPrices valueForKey:@"currencyCode"]; NSNumberFormatter *numberFormatter = [[[NSNumberFormatter alloc] init] autorelease]; [numberFormatter setFormatterBehavior:NSNumberFormatterBehavior10_4]; [numberFormatter setCurrencyCode:currencyCode]; [numberFormatter setNumberStyle:NSNumberFormatterCurrencyStyle]; NSString *currencySymbol = [numberFormatter currencySymbol];

• Application crash when using an NSTimer and pushViewController

  - by Cesar

  I'm using an NSTimer to implement a 3 seconds splash screen. If a don't use a timer the view it's correctly pushed but if I use the timer for adding a little delay the application crash with a EXC_BAD_ACCESS. I'm pretty sure the answer contains "memory management" but I can't get the point... @interface RootViewController : UIViewController { NSTimer *timer; } -(void)changeView:(NSTimer*)theTimer; @property(nonatomic,retain) NSTimer *timer; ... @implementation RootViewController @synthesize timer; - (void)viewDidAppear:(BOOL)animated { [super viewDidAppear:animated]; [[self navigationController] setNavigationBarHidden:YES]; timer = [NSTimer scheduledTimerWithTimeInterval:3.0 target:self selector:@selector(changeView:) userInfo:nil repeats:NO]; } -(void)changeView:(NSTimer*)theTimer { NSLog(@"timer fired"); //Crash here, but only if called using a timer [[self navigationController] pushViewController:list animated:YES]; }

• Perl file test operator help

  - by Aaron Moodie

  This is a really basic issue, but I'm new to perl and cannot work out what the issue is. I'm just trying to isolate the files in a directory, but the -d operator keeps treating all the folder contents as files ... @contents is my array, and when I run this: foreach $item(@contents) { if (-d $item) { next; } print"$item is a file\n"; } I keep getting both folders and files. Alternatively, if I use -f, I get nothing. edit: this is the output - file01.txt is a file folder 01 is a file folder 02 is a file Screen shot 2010-04-18 at 1.26.17 PM.png is a file I'm running this on OSX

• What is the life cycle of the XNA GraphicsDevice on the Xbox 360?

  - by David Brown

  I'm working on an XNA project that doesn't use the built-in Game class, mostly for learning purposes (so I can mess with different game loop types, etc). It's only designed for the Xbox 360, because the hardware is consistent and I don't have to worry about compatibility among different PC hardware configurations. So far, it's working well and I can clear the screen to a color, but I'd like to make sure I handle the GraphicsDevice correctly before moving on. What exactly is the life cycle for the GraphicsDevice on the Xbox 360? Is it ever lost or reset automatically? I know that on Windows, it's lost when the window loses focus, but the Xbox obviously doesn't manage focus. It appears to even keep the graphics device when the Guide pops up, which is the closest thing I can find to "losing focus" on the Xbox. I'd like to think it's simply a matter of "fire and forget," which would make a lot of other things much easier (only needing to load content once, for instance). But I want to make sure.

• Simple, non-blocking way to sleep?

  Hello I googled for this and read some threads here, but I haven't found a simple way to have a VB.Net application sleep for a little while and still keep the application responsive: Imports System.Net Imports System.IO Imports System.Text Imports System.Text.RegularExpressions Imports System.Threading.Thread [...] 'How to keep screen frop freezing? While True ListBox1.Items.Clear() ListBox1.Items.Add("blah") 'Not much difference ListBox1.Refresh() 'Wait 1mn Sleep(60000) End While Is there really no simple, non-blocking solution to have a VB.Net application wait for a few seconds?

• Am I crazy? (How) should I create a jQuery content editor?

  - by Brendon Muir

  Ok, so I created a CMS mainly aimed at Primary Schools. It's getting fairly popular in New Zealand but the one thing I hate with a passion is the largely bad quality of in browser WYSIWYG editors. I've been using KTML (made by InterAKT which was purchased by Adobe a few years ago). In my opinion this editor does a lot of great things (image editing/management, thumbnailing and pretty good content editing). Unfortunately time has had its nasty way with this product and new browsers are beginning to break features and generally degrade the performance of this tool. It's also quite scary basing my livelihood on a defunct product! I've been hunting, in fact I regularly hunt around to see if anything has changed in the WYSIWYG arena. The closest thing I've seen that excites me is the WYSIHAT framework, but they've decided to ignore a pretty relevant editing paradigm which I'm going to outline below. This is the idea for my proposed editor, and I don't know of any existing products that can do this properly: Right, so the traditional model for editing let's say a Page in a CMS is to log into a 'back end' and click edit on the page. This will then load another screen with the editor in it and perhaps a few other fields. More advanced CMS's will maybe have several editing boxes that are for different portions of the page. Anyway, the big problem with this way of doing things is that the user is editing a document outside of the final context it will appear in. In the simplest terms, this means the page template. Many things can be wrong, e.g. the with of the editing area might be different to the width of the actual template area. The height is nearly always fixed because existing editors always seem to use IFRAMES for backward compatibility. And there are plenty of other beefs which I'm sure you're quite aware of if you're in this development area. Here's my editor utopia: You click 'Edit Page': The actual page (with its actual template) displays. Portions of the page have been marked as editable via a class name. You click on one of these areas (in my case it'd just be the big 'body' area in the middle of the template) and a editing bar drops down from the top of the screen with all your standard controls (bold, italic, insert image etc...). Iframes are never used, instead we rely on setting contentEditable to true on the DIV's in question. Firefox 2 and IE6 can go away, let's move on. You can edit the page knowing exactly how it will look when you save it. Because all the styles for this template are loaded, your headings will look correct, everything will be just dandy. Is this such a radical concept? Why are we still content with TinyMCE and that other editor that is too embarrassing to use because it sounds like a swear word!? Let's face the facts: I'm a JavaScript novice. I did once play around in this area using the Javascript Anthology from SitePoint as a guide. It was quite a cool learning experience, but they of course used the IFRAME to make their lives easier. I tried to go a different route and just use contentEditable and even tried to sidestep the native content editing routines (execCommand) and instead wrote my own. They kind of worked but there were always issues. Now we have jQuery, and a few libraries that abstract things like IE's lack of Range support. I'm wondering, am I crazy, or is it actually a good idea to try and build an editor around this editing paradigm using jQuery and relevant plugins to make the job easier? My actual questions: Where would you start? What plugins do you know of that would help the most? Is it worth it, or is there a magical project that already exists that I should join in on? What are the biggest hurdles to overcome in a project like this? Am I crazy? I hope this question has been posted on the right board. I figured it is a technical question as I'm wanting to know specific hurdles and pitfalls to watch out for and also if it is technically feasible with todays technology. Looking forward to hearing peoples thoughts and opinions.

• How to detect a Triangle gesture with kinect?

  - by Akhilesh Mishra

  I am trying to implement a gesture recognition system which interprets the geometric gestures user makes and draws it on screen, I have some idea of how circle can be recognized, however i have no clue how to get started with triangle recognition. the data I have is X and Y coordinates of all points the gesture passed through. I get this data by tracking right hand. I found something online called Hough Transform , which is used for detecting lines but i am not sure whether it will work for discrete collection of points, Any ideas folks?

• contentoffset during flick gesture

  - by Michael Xu

  Hi all, Does anyone else notice that the contentOffset of UIScrollView doesnt update during a flick gesture? It only updates after the flick gesture has totally completed, when the flick gesture is finished. After the finger has left the screen, the scrollview keeps moving, in the decelerating phase. but this isnt reflected in the contentOffset of the UIScrollView. Is there a way to track where the contentOffset is during the decelerating part of the flick gesture? I have an OpenGL layer on top, and i want it to move with the scrollView. Can't seem to get the right info out of the scrollview though... Thoughts? thanks, michael

• Keep Windows Mobile 6 phone alive

  - by QAH

  I am making an application for Windows Mobile 6.1 Pocket PC (Touchscreen). I know when a Pocket PC's screen turns off, it goes into a standby mode and applications are pretty much halted in the background. My application can't do that. It needs to keep going. So my question is, how can I keep the phone alive (backlight turned on) until my application is done? An example of this would be video streaming applications such as Youtube. It keeps the phone on while the video is playing.

• SQL University: What and why of database refactoring

  - by Mladen Prajdic

  This is a post for a great idea called SQL University started by Jorge Segarra also famously known as SqlChicken on Twitter. It’s a collection of blog posts on different database related topics contributed by several smart people all over the world. So this week is mine and we’ll be talking about database testing and refactoring. In 3 posts we’ll cover: SQLU part 1 - What and why of database testing SQLU part 2 - What and why of database refactoring SQLU part 3 - Tools of the trade This is a second part of the series and in it we’ll take a look at what database refactoring is and why do it. Why refactor a database To know why refactor we first have to know what refactoring actually is. Code refactoring is a process where we change module internals in a way that does not change that module’s input/output behavior. For successful refactoring there is one crucial thing we absolutely must have: Tests. Automated unit tests are the only guarantee we have that we haven’t broken the input/output behavior before refactoring. If you haven’t go back ad read my post on the matter. Then start writing them. Next thing you need is a code module. Those are views, UDFs and stored procedures. By having direct table access we can kiss fast and sweet refactoring good bye. One more point to have a database abstraction layer. And no, ORM’s don’t fall into that category. But also know that refactoring is NOT adding new functionality to your code. Many have fallen into this trap. Don’t be one of them and resist the lure of the dark side. And it’s a strong lure. We developers in general love to add new stuff to our code, but hate fixing our own mistakes or changing existing code for no apparent reason. To be a good refactorer one needs discipline and focus. Now we know that refactoring is all about changing inner workings of existing code. This can be due to performance optimizations, changing internal code workflows or some other reason. This is a typical black box scenario to the outside world. If we upgrade the car engine it still has to drive on the road (preferably faster) and not fly (no matter how cool that would be). Also be aware that white box tests will break when we refactor. What to refactor in a database Refactoring databases doesn’t happen that often but when it does it can include a lot of stuff. Let us look at a few common cases. Adding or removing database schema objects Adding, removing or changing table columns in any way, adding constraints, keys, etc… All of these can be counted as internal changes not visible to the data consumer. But each of these carries a potential input/output behavior change. Dropping a column can result in views not working anymore or stored procedure logic crashing. Adding a unique constraint shows duplicated data that shouldn’t exist. Foreign keys break a truncate table command executed from an application that runs once a month. All these scenarios are very real and can happen. With the proper database abstraction layer fully covered with black box tests we can make sure something like that does not happen (hopefully at all). Changing physical structures Physical structures include heaps, indexes and partitions. We can pretty much add or remove those without changing the data returned by the database. But the performance can be affected. So here we use our performance tests. We do have them, right? Just by adding a single index we can achieve orders of magnitude performance improvement. Won’t that make users happy? But what if that index causes our write operations to crawl to a stop. again we have to test this. There are a lot of things to think about and have tests for. Without tests we can’t do successful refactoring! Fixing bad code We all have some bad code in our systems. We usually refer to that code as code smell as they violate good coding practices. Examples of such code smells are SQL injection, use of SELECT *, scalar UDFs or cursors, etc… Each of those is huge code smell and can result in major code changes. Take SELECT * from example. If we remove a column from a table the client using that SELECT * statement won’t have a clue about that until it runs. Then it will gracefully crash and burn. Not to mention the widely unknown SELECT * view refresh problem that Tomas LaRock (@SQLRockstar on Twitter) and Colin Stasiuk (@BenchmarkIT on Twitter) talk about in detail. Go read about it, it’s informative. Refactoring this includes replacing the * with column names and most likely change to application using the database. Breaking apart huge stored procedures Have you ever seen seen a stored procedure that was 2000 lines long? I have. It’s not pretty. It hurts the eyes and sucks the will to live the next 10 minutes. They are a maintenance nightmare and turn into things no one dares to touch. I’m willing to bet that 100% of time they don’t have a single test on them. Large stored procedures (and functions) are a clear sign that they contain business logic. General opinion on good database coding practices says that business logic has no business in the database. That’s the applications part. Refactoring such behemoths requires writing lots of edge case tests for the stored procedure input/output behavior and then start to refactor it. First we split the logic inside into smaller parts like new stored procedures and UDFs. Those then get called from the master stored procedure. Once we’ve successfully modularized the database code it’s best to transfer that logic into the applications consuming it. This only leaves the stored procedure with common data manipulation logic. Of course this isn’t always possible so having a plethora of performance and behavior unit tests is absolutely necessary to confirm we’ve actually improved the codebase in some way.   Refactoring is not a popular chore amongst developers or managers. The former don’t like fixing old code, the latter can’t see the financial benefit. Remember how we talked about being lousy at estimating future costs in the previous post? But there comes a time when it must be done. Hopefully I’ve given you some ideas how to get started. In the last post of the series we’ll take a look at the tools to use and an example of testing and refactoring.

• Can't create flex4 project in flexbuilder using remoting or LiveCycle Data Servcies ES

  - by anopres

  I'm trying out the FlasBuilder ide with ColdFusion 8 on OS X. When I try to create a new project, I get stuck at the server setup screen that forces you to validate your paths for your ColdFusion root folder and your webroot. Every combination I try says either "LiveCycle Data Services is not installed at the specified location" or "Invalid root. The WEB-INF/flex folder must contain either flex-config.xml or services-config.xml." The flex-config.xml file is sitting in that directory. Is there some trick to getting this to work?

• Scaled live iPhone Camera view in center, "CGAffineTransformTranslate" not working

  - by Gavin

  Hi, I have a little problem which I could not solve. I really hope someone can help me with that. I wanted to resize the live camera view and place it in the center, using the following code below: picker.cameraViewTransform = CGAffineTransformScale(picker.cameraViewTransform, 0.5, 0.56206); picker.cameraViewTransform = CGAffineTransformTranslate(picker.cameraViewTransform, 80, 120); But all I got was a scaled 1/2 sized view on the top left of the screen. It seems as though "CGAffineTransformTranslate" does nothing at all. The translation didn't work even when I used: picker.cameraViewTransform = CGAffineTransformMake(1, 0, 0, 1, 80, 120); The translation portion seems to have no effect on the live camera view. Hope someone can enlighten me. Thanks.
