• tabIndex fails in an AS3 swf loaded into a flex app

  - by quoo

  I feel like I'm missing something really simple here. I'm loading a AS3 swf containing a form (created by one of our designers) into a flex app. The swf's tabIndex properties work fine when the swf is viewed by itself, however, once it's loaded into the flex app: <mx:SWFLoader source="form.swf" top="20" horizontalCenter="0" id="formSwf" complete="swfCompleteHandler(event)"/> the form fields stop receiving focus on tab. I've been looking at the FocusManager in flex, for some sort of solution, but I can't seem to find any examples, and I'm not entirely sure I'm looking in the right place. Am I stuck redoing this form in flex?

• Best way for allowing subdomain session cookies using Tomcat

  - by Andrew Ingram

  By default tomcat will create a session cookie for the current domain. If you are on www.example.com, your cookie will be created for www.example.com (will only work on www.example.com). Whereas for example.com it will be created for .example.com (desired behaviour, will work on any subdomain of example.com as well as example.com itself). I've seen a few Tomcat valves which seem to intercept the creation of session cookies and create a replacement cookie with the correct .example.com domain, however none of them seem to work flawlessly and they all appear to leave the existing cookie and just create a new one. This means that two JSESSIONID cookies are being sent with each request. I was wondering if anybody has a definitive solution to this problem.

• How to apply text shadow to UITextView?

  - by mystify

  Actually I love UILabel. They're sweet. Now I had to go to UITextView because UILabel is not aligning text vertically to the top. Damn. One thing I really need is a text shadow. UILabel has it. UITextView seems to not have it. But I guess that guy just uses the same underlying UIKit NSString additions?? Maybe someone already has a solution for that problem? What would I overwrite?

• Indy FTP, large files and NAT routers

  - by Lobuno

  Hello! I have been using Indy to transfers files via FTP for years now but have not been able to find a satisfactory solution for the following problem. When a user is uploading a large file, behind a router, sometimes the following happens: the file is uploaded OK, but under the mean time the command channel gets disconnected because of a timeout. Normally this doesn't happens with a direct connection to the server, because the server "knows" that a transfer is being taking place on the data channel. Some routers are not aware of this, though and the command channel is closed. Many programs send a NOOP command periodically to keep the command channel alive even if this is not part of the standard FTP specification. My question: how do I do that? Do I send the NOOP command in the OnWork event? Does this cause any collateral damage in some way, like, do I need to process some response? How do I best solve this problem?

• Algorithm and data structure learning resources for dynamic programming

  - by Pranav

  Im learning dynamic programming now, and while I know the theory well, designing DP algorithms for new problems is still difficult. This is what i would really like now- A book or a website, which poses a problem which can be solved by dynamic programming. Also there is the solution with an explanation available, which i would like to see if i cant solve the problem even after butting my head at it for a few hours. Is there some resource that provides this sort of a thing for several categories of algorithms- like graph algorithms, dynamic programming, etc? P.S. I considered Topcoder, but the solutions there are not really appropriate for learning to implement efficient solutions.

• Best reverse proxy for IIS 6?

  - by Chris

  I want to set up a reverse proxy from one of our intranet IIS sites to point to another tomcat server. Eg, i want the user to browse to 'http://our-iis-server/friendly-url' and for it to reverse proxy to 'http://our-tomcat-server/ugly-url'. What would be the best solution for this? I've narrowed it down to three options: http://www.managedfusion.com/products/url-rewriter/documentation.aspx http://www.isapirewrite.com/ http://www.codeplex.com/IIRF Also, can these tools rewrite the links in the html? Eg, if the tomcat server's html has something like 'a href = http://our-tomcat-server/ugly-url/product/widget' i would need it to change to 'a href = http://our-iis-server/friendly-url/product/widget' Thanks in advance. All good answers will be voted for!!!

• how callback a function on 404 on JSON ajax request with Jquery?

  - by shingara

  I want made an Ajax request with response on JSON. So I made this Ajax request : $.ajax({ url: 'http://my_url', dataType: "json", success: function(data){ alert('success'); }, error: function(data){ alert('error'); }, complete: function(data) { alert('complete') }}) This code works good but when my url send me a HTTP code 404, no callbacks are used, even the complete callback. After research, it's because my dataType is 'json' so 404 return is HTML and the JSON parsing failed. So no callback. Have you a solution to call a callback function when a 404 is raised ? EDIT: complete callback don't call is return is 404. If you want an URL wit 404 you can call : http://twitter.com/status/user_timeline/jksqdlmjmsd.json?count=3&callback=jsonp1269278524295&_=1269278536697 it's with this URL I have my problem.

• Speed improvements for Perl's chameneos-redux in the Computer Language Benchmarks Game

  - by Robert P

  Ever looked at the Computer Language Benchmarks Game (formerly known as the Great Language Shootout)? Perl has some pretty healthy competition there at the moment. It also occurs to me that there's probably some places that Perl's scores could be improved. The biggest one is in the chameneos-redux script right now—the Perl version runs the worst out of any language: 1,626 times slower than the C baseline solution! There are some restrictions on how the programs can be made and optimized, and there is Perl's interpreted runtime penalty, but 1,626 times? There's got to be something that can get the runtime of this program way down. Taking a look at the source code and the challenge, how can the speed be improved?

• Concatenate boost::dynamic_bitset or std::bitset

  - by MOnsDaR

  Hey, what is the best way to concatenate 2 bitsets? For example i've got boost::dynamic_bitset<> test1( std::string("1111") ); boost::dynamic_bitset<> test2( std::string("00") ); they should be concatenated into a thrid Bitset test3 which then holds 111100 Solutions should use boost::dynamic_bitset. If the solution works with std::bitset, it would be nice too. There should be a focus on performance when concatenating the bits.

• Tracking fitness in a genetic algorithm

  - by Chuck Vose

  I'm still hacking on my old ruby for the undead post (I know, I know, stop trying to bring the post back from the dead Chuck). But the code has gotten a little out of hand and now I'm working on a genetic algorithm to create the ultimate battle of living and dead with the fitness being how long the battle lasts. So, I've got the basics of it down; how to adjust attributes of the game and how to acquire the fitness of a solution, what I can't figure out is how to store the fitness so that I know when I've tried a combination before. I've not been able to find much genetic code to look at let alone code that I can read well enough to tell what's going on. Does anyone have an idea how this is normally done or just simply an algorithm that could help point me in the right direction?

• Breakpoints are ignored when debugging in Visual Studio 2008 on 64-bit system

  - by Arnold Zokas

  I'm trying to debug an ASP.NET web application in this environment: Windows Server Standard 2008 SP2 x64 Single-core CPU 4GB RAM Visual Studio 2008 with Remote Debugger SP1 .NET 3.5 Web Application running in IIS in 64-bit mode The code I am trying to debug is a simple event handler with some basic sequential code. What I observe is that breakpoints get randomly ignored and VS often exits debug mode when I try to step through the code. The code is compiled in debug mode. I've tried all the usual steps: iisreset, reboot VM, rebuild solution, reinstall Visual Studio. Any ideas?

• Eclipse CDT: Import source / header files into my new project, without duplicating them

  - by Tom

  Hi all, Im sure there is a very simple solution for this. I have a bunch of .cpp / .h files from a project, say in directory ~/files On the other hand, I want to create a c++ project using eclipse to work on those files, so I put my workspace on ~/wherever. Then I create a c++ project: ~/wherever/project, and include the source files (located in /~files). The problem i'm having is that files are now duplicated in ~/wherever/project, and I would like to avoid that, specially so I know which copy of the file to commit. Is this possible? Im sure it is, but cant get it. Thanks in advance.

• Javascript DateFormat for different timezones

  - by Elie

  I'm a Java developer and I'm used to the SimpleDateFormat class that allows me to format any date to any format by settings a timezone. Date date = new Date(); SimpleDateFormat sdf = new SimpleDateFormat("dd-MM-yyyy hh:mm:ss"); sdf.setTimeZone(TimeZone.getTimeZone("America/Los_Angeles")); System.out.println(sdf.format(date)); // Prints date in Los Angeles sdf.setTimeZone(TimeZone.getTimeZone("America/Chicago")); System.out.println(sdf.format(date)); // Prints same date in Chicago SimpleDateFormat is a pretty neat solution in Java but unfortunately I can't find any similar alternative in Javascript. I'm extending the Date prototype in Javascript to do exactly the same. I have dates in Unix format but I want to format them in different timezones. Date.prototype.format = function(format, timezone) { // Now what? return formattedDate; } I'm looking for a neat way to do this rather than a hack. Thanks

• How to Debug XAML Parsing Errors in Silverlight?

  - by Nick Gotch

  I run into the following issue semi-regularly: I make changes to XAML or some resources used by it and when I go to load up the Silverlight project in debug mode it only gets as far as the spinning Silverlight-loading animation. I've tried attaching the VS08 debugger to the process but it doesn't do anything at this point (works fine once I'm in the Silverlight but not before.) From previous experience I've noticed this happens when there're problems with the XAML or the resources in it but my only solution so far has been to dissect the code line-by-line until I spot the problem. Is there an easy way to debug/diagnose these situations? UPDATE I found this question with some help, but it still doesn't provide a good way to debug these types of issues.

• Back button loop with IFRAMES

  - by Tim Jackson

  In my (school) website we use Iframes to display class blogs (on blogger). This works well EXCEPT if the user then clicks on (say) a photo inside the iframe. Blogger (in this case) then displays the photo in the whole browser window and the back button loops; that is if the back button is hit, the browser (IE, FF, Chrome) stays on the same page. The only way out is for the user to jump back two pages (which many of our users don't know how to do). I've read a lot of posts on back buttons and iframes and there doesn't appear to be a simple solution. Bear in mind that I don't have control over the iframe content (so no embedded back buttons in the frame are possible). Ideas anyone?

• Need advice on speeding up tableViewCell photo loading performance

  - by ambertch

  I have around 20 tableview cells that each contain a number (2-5) thumbnail sized pictures (they are VERY small Facebook profile pictures, ex. http://profile.ak.fbcdn.net/hprofile-ak-sf2p/hs254.snc3/23133_201668_2989_q.jpg). Each picture is an UIImageView added to the cell's contentview. Scrolling performance is poor, and measuring the draw time I've found the UIImage rendering is the bottleneck. I've researched/thought of some solutions but as I am new to iphone development I am not sure which strategy to pursue: preload all the images and retrieve them from disk instead of URL when drawing cells (I'm not sure if cell drawing will still be slow, so I want to hold off on the time investment here) Have the cells display a placeholder image from disk, while the picture is asynchronously loaded (this seems to be the best solution, but I'm currently not sure exactly how to do best do this) There's the fast drawing recommendation from Tweetie, but I don't know that will have much affect if it turns out my overhead is in network loading (http://blog.atebits.com/2008/12/fast-scrolling-in-tweetie-with-uitableview/) Thoughts/implementation advice? Thanks!

• Visual Studio 2008 - The breakpoint cannot be hit

  - by Josh

  I know that many people have had this problem... but I am now having it and cannot solve the issue. VS 2008 is randomly giving me an error after working on a project for weeks. When I set a debug point, I get a warning: The breakpoint will not currently be hit. No symbols have been loaded for this document. I have re-built the solution with no debug points and re-tried. I have also tried to Load Symbols from path and that has not worked either... Can someone please help walk me through the necessary steps to getting my debug function working again. Thanks.

• How to Edit NSF file using c#?

  - by Preeti

  Hi, I want to programaticaly change some values to NSF item and then want to save it.(i.e to edit NSF File and then save the editions) for example: I want to set Sender name of all mails to "[email protected]".(Using Domino.dll). Solution I tried: (Swaping of To and From values) String Temp_From = ((object[])docInbox.GetItemValue("From"))[0] as String; String Temp_SendTo = ((object[])docInbox.GetItemValue("SendTo"))[0] as String; docInbox.ReplaceItemValue("From", Temp_SendTo); docInbox.ReplaceItemValue("SendTo", Temp_From); docInbox.Save(true, false, false); /* Applied for following fields also: For From: AltFrom,DisplayFrom,DisplayFrom_2,dspFrom,ForwardedFrom,INetFrom,tmpDisplayFrom For To : displaySendTo,EnterSendTo,Envelope_to,tmpDisplaySendTo Also Tried for saving : docInbox.Save(true, true, true); */ In above code after successful editing changes values are not reflected in Nsf File. But when i am reading edited Nsf (copying modified file on different location ) file programatically it is showing changed values.(Why changes are not visible here ?)

• How to programmatically answer "Yes" to WebBrowser control security alert

  - by ih8ie8

  I am using WebBrowser control to programmatically access a single website, but whenever I login, I receive this certificate security alert: Since I trust that website and since I need to programmatically automate the login as well, this dialog box gets in the way. I searched SO for a solution and found a question similar to mine, but the accepted answer does not work! I defined a static member in the form that contains the WebControl: public static bool ValidateServerCertificate(object sender, X509Certificate certificate, X509Chain chain, SslPolicyErrors sslPolicyErrors) { return true; } In my form's constructor I added: ServicePointManager.ServerCertificateValidationCallback = new RemoteCertificateValidationCallback(ValidateServerCertificate); But that didn't get rid of the certificate security alert. Is there any way to get rid of this warning? Is there an IE equivalent to Firefox's Add Security Exception??? Note: The owner's certificate works perfectly fine (without exhibiting this security alert) with standalone browsers (IE, FF, Chrome, Safari). It only exhibits the problem with the WebBroswer control.

• JAVA Calendar - How to check if it's Saturday/Sunday ?

  - by Cristian

  What this code does is print the dates of the current week from Monday to Friday. It works fine, but I want to ask something else: If today is Saturday or Sunday I want it to show the next week... how do I do that? Here's my working code so far (thanks to StackOverflow!!): // Get calendar set to current date and time Calendar c = Calendar.getInstance(); // Set the calendar to monday of the current week c.set(Calendar.DAY_OF_WEEK, Calendar.MONDAY); // Print dates of the current week starting on Monday to Friday DateFormat df = new SimpleDateFormat("EEE dd/MM/yyyy"); for (int i = 0; i <= 4; i++) { System.out.println(df.format(c.getTime())); c.add(Calendar.DATE, 1); Thanks a lot! I really appreciate it as I've been searching for the solution for hours...

• Error using ASP.NET 3.5 Chart control within a Repeater control

  - by tuseau

  Hi, I'm getting the error "Microsoft JScript runtime error: Sys.WebForms.PageRequestManagerServerErrorException: Error executing child request for ChartImg.axd" at runtime from my Chart control. I have read one solution to this error message as documented here: http://social.msdn.microsoft.com/Forums/en-US/MSWinWebChart/thread/1dc4b352-c9a5-49dc-8f35-9b176509faa1/ but this does not solve my problem. I have the Chart within a Repeater control, which is within an ajax UpdatePanel. When I take the chart out of the Repeater (but leave it in the UpdatePanel), it works. So I'm thinking it is to do with the Repeater. Anyone got any ideas? Thanks in advance.

• Visual Studio 2008 debug does not stop on error

  - by Diana

  I have a simple Windows App written in Visual Studio 2008 (.NET 3.0, C#). Without making any change to the project, solution or Visual Studion (from what I can remember), something weird is happening: when I debug (or run) my application, when it hits an error, Visual Studio does not show me any messagebox with the error, and does not stop execution. It "looks" like nothing happended... the code after the error is not executed, but everything else continues to behave like nothing had happened. Any ideeas about what might be wrong? I don't think it's a big deal, but I can't seem to find it. Thanks!

Do you please have a solution to have a fixed height with jquery.ui.autocomplete and a scroll bar working with IE ? Thank you very much

  My task is to move this VS solution and projects to another SVN server. I'm working with Visual Studio 2010 RC1 and AnkhSVN 2.1.7819.... Currently the files are all bound to a repo at C:\Repositories\foo. I'd like to move it to http://someSite/svn/foo I'm presented with this error message: Repository UUID '152c39db-5799-4234-85f2-074004a6fcad' doesn't match expected UUID '6c83444d-7f93-d64a-b0a0-23283495cf17' Questions How can I avoid this message in AnkhSVN? Are there better solutions for moving the source into a repo on the new target? How can I get Ankh to 'forget' that repo at C:\Repositories\ forever?
