• Using jQuery to rapidly scroll through a countdown

  - by CaptainAwesomePants

  I have a webpage that displays the number 0, and when the user presses "start", the number should rapidly increasing until it reaches a target number (maybe 10,000 or so) a few seconds later. I'd like the numbers to scroll by as if they're on a slot machine wheel. I've managed to mostly hack something together using the ScrollTo plugin, but it's slow and choppy. It always stops briefly at certain divs along the way. Perhaps I'm using it wrong. Is there a better way to accomplish such an effect?

• How to assign fine grained permission on shared mailboxes?

  - by sudhirc

  Typically you can assign either Full and Sendas permissions to mailboxes using Powershell. In our organization we have a need to assign other fine grained permissions like editor, reader , author to the shared mailboxes. We are using a third party tool to achieve this. I am pretty happy with the tool except for that fact that it is a GUI only tool. I am trying to automate the entire process of shared mailbox creation by using a combination of embedded powershell in C# program. All other steps are easy to automate but because this tool is GUI only, I am really struck. Is there an API method available to to achieve this? I guess EWS API can provide some answer but I really do not know where to start.

• Best way to return a user-generated file, AJAX or Forms?

  - by Bill Zimmerman

  Hi, I'm new to web programming, so I need some help. I am writing a custom file-creation app for my site. A user visits the page, clicks on some various options and toggles some checkboxes, and the presses a 'download now' link. I have a PHP backend which will be processing the submission, and generating a PDF file. After the user presses the download link, I want the download to start like it would for any static link. My question is: What is the best way to do this? From my limited understanding, I have a choice between using AJAX or somehow using forms to submit the data. What are the advantages/disadvantages of each? Does anyone have any good links to examples? Thanks

• Xcode, Dev Docs Search Field Loosing Focus?

  - by fuzzygoat

  I am having a strange issue with the developer documentation (which i have only noticed after installing Xcode 3.2.3). My problem is that as you type in the search field (upper right) it looses focus and immediately starts looking for the first few letters you type. For example if you looking for "NSObject" you start typing "NSO" and as you type the field looses focus the last 5 characters "bject" just give beeps as you need to reselect the field to type extra characters. Has anyone else come across this or know what the problem might be? cheers Gary.

• JavaScript - Textarea Selection

  - by brad

  The Problem I am working on an in-browser editor within a textarea. I have started looking for some information on dealing with textarea selection and found this jQuery plugin that does some simple manipulation. However, it doesn't explain what's going on. The Question Where can I find a good resource on Textarea Selection in JavaScript, preferably with a description of both pre-DOM3 and post-DOM30 scenarios? [Edit] In a great answer from Borgar, I have found several different places to start with contentEditable, selectionStart, and selectionEnd. I'll be looking into these things and posting any good tutorials I might find.

• Rectangular BackColor of selection in RichTextBox

  - by AgentConundrum

  Background: I'm going to start studying/coding at the local university's library. Since I'm not a student, I won't be able to utilize their wireless internet access. Since StackOverflow is such a great resource, I want to be able to take it with me, so I'm building a small desktop application to load/search/display the most recent data dumps. Problem: I want to display code blocks in the same sort of rectangular block as this site does, so I played with the RichTextBox control to try to create this effect. Unfortunately, the RichTextBox.SelectedBackColor property only colors the actual text, when what I want is a rectangle reaching to the outer limits of the selection. Example: This is what I am able to produce with the RichTextBox: This is what I would like to create: Questions: Is there any way to produce this effect using the RichTextBox? If not, are there any other controls I could use to create this effect?

• rsync over ssh is not working anymore, while ssh itself is working fine (Write failed: broken pipe)

  - by brazorf

  This issue started happening after i changed router. This is the scenario: Windows7 Host Ubuntu 10.04 Guest (VirtualBox) Ubuntu 10.04 remote server What i used to do is run a very basic rsync command: rsync -avz --delete /local/path/ username@host:/path/to/remote/directory This worked perfect until i did change adsl provider, and i changed router aswell: now, this happens: rsync on Ubuntu Guest is not working anymore (to any random server), if using this new router rsync on Ubuntu Guest is WORKING, if i switch back to old router i tried a new virtual box ubuntu install, and the command is WORKING with both the routers So, the not-working-combo is oldUbuntu + newRouter. To get things worst, i can state that (on the not-working ubuntu) i ping the remote host plain ssh connection to the remote host is working fine (i can auth, connect, and do stuff on the remote host) scp is NOT working (this is just a further thing i tried) This is the console output of the execution, with ssh verbose set to vvvv: root@client:~# rsync -ae 'ssh -vvvv' /root/test-rsync/

• Qt for Symbian - Detecting touch/non-touch devices...

  - by Nikos

  I'm porting a game for Symbian which supports both a touch & non-touch UI. I need to be able to tell if the device has a touch screen on start-up so I can enable the appropriate mode. After googling for hours and going though the Qt Docs I found QSysInfo but this merely provides the version of the Symbian device. Is there a way to get the actual capabilities of the device? There must be a way to tell if the device has a touch screen...! I'm using the latest QtCreator with the NokiaSDK. Thank you in advance, Nikos.

• Scan from last instance of character to end of string using NSScanner

  - by Virgil Disgr4ce

  Given a string such as: "new/path - path/path/03 - filename.ext", how can I use NSScanner (or any other approach) to return the substring from the last "/" to the end of the string, i.e., "03 - filename.ext"? The code I've been trying to start with is: while ([fileScanner isAtEnd] == NO){ slashPresent = [fileScanner scanUpToString:@"/" intoString:NULL]; if (slashPresent == YES) { [fileScanner scanString:@"/" intoString:NULL]; lastPosition = [fileScanner scanLocation]; } NSLog(@"fileScanner position: %d", [fileScanner scanLocation]); NSLog(@"lastPosition: %d", lastPosition); } ...and this results in a seg fault after scanning to the end of the string! I'm not sure why this isn't working. Ideas? Thanks in advance!

• Using a Cross Thread Boolean to Abort Thread

  - by Jon

  Possible Duplicate: Can a C# thread really cache a value and ignore changes to that value on other threads? Lets say we have this code: bool KeepGoing = true; DataInThread = new Thread(new ThreadStart(DataInThreadMethod)); DataInThread.Start(); //bla bla time goes on KeepGoing = false; private void DataInThreadMethod() { while (KeepGoing) { //Do stuff } } } Now the idea is that using the boolean is a safe way to terminate the thread however because that boolean exists on the calling thread does that cause any issue? That boolean is only used on the calling thread to stop the thread so its not like its being used elsewhere

• Resources for TDD aimed at Python Web Development

  - by Null Route

  I am a hacker not and not a full-time programmer but am looking to start my own full application development experiment. I apologize if I am missing something easy here. I am looking for recommendations for books, articles, sites, etc for learning more about test driven development specifically compatible with or aimed at Python web application programming. I understand that Python has built-in tools to assist. What would be the best way to learn about these outside of RTFM? I have searched on StackOverflow and found the Kent Beck's and David Astels book on the subject. I have also bookmarked the Wikipedia article as it has many of these types of resources. Are there any particular ones you would recommend for this language/application?

• building a web application in eclipse

  - by Noona

  As a concluding assignment for the technologies taught in a data management course, we have to write a web application using the technologies taught throughout the course, this mostly includes xhtml, css, JSP, servelets, JDBC, AJAX, webservices. the project will eventually be deployed using tomcat. we are given the option of choosing the technologies that we see fit. since this is my first time developing a web application I am having some uncertainties about where to start, so for example now I am writing the object classes that will be used in the database and implementing the operations that will be performed on the database, but I am not sure about how to make these operations available to a client through the website, I mean I think I have to write a servlet through which I can extract the request parameters and set the response accordingly, but I would still like a more specific overview of what I am going to do, so if someone can link me to a tutorial with an example that makes use of these technologies while illustrating the stages of the design so that I can see how all these things are linked together in a web project. thanks

• The Cleanest Reset for ARM Processor

  - by waffleman

  Lately, I've been cleaning up some some C code that runs on an ARM7 controller. In some situations (upgrade, fatal error, etc...) the program will perform a reset. Presently it just jumps to 0 and assumes that the start-up code will reinitialize everything correctly. It got me to thinking about what would be the best procedure a la "Leave No Trace" for an ARM reset. Here is my first crack at it: void Reset(void) { /* Disable interrupts */ __disable_interrupts(); /* Reset peripherals, externals and processor */ AT91C_BASE_RSTC->RSTC_RCR = AT91C_RSTC_KEY | AT91C_RSTC_PERRST | AT91C_RSTC_EXTRST| AT91C_RSTC_PROCRST; while(AT91C_BASE_RSTC->RSTC_RSR & AT91C_RSTC_SRCMP); /* Jump to the reset vector */ (*(void(*)())0)(); } Anything I haven't considered?

• WCF competitive consumer pattern

  - by Simon Thompson

  Is it possible to create a WCF service (web service) that only accepts a single connection at any one time with all other calls either queued or rejected. Need to implement the competitive consumer pattern where there are a number of clients which could deal with task at hand but when a client askes for more work a task must go to only one of them. Usual done as part of an enterprise service bus but can not find one that I'm happy to start using so looking to get this behaviour through a WCF service. Any ideas people ?

• Advanced MySQL Search Help

  - by Brandon

  I've been trying to come up with something for a while now to no avail. My MySQL knowledge is rudimentary at best so I could use some guidance on what I should use for the following: I have 2 tables ('bible' and 'books') that I need to search from. Right now I am just searching 'bible' with the following query: SELECT * FROM bible WHERE text LIKE '%" . $query . "%' ORDER BY likes DESC LIMIT $start, 10 Now, I need to add another part that searches for some pretty advanced stuff. Here is what I want to do in pseudocode which I am aware doesn't work: SELECT * FROM bible WHERE books.book+' '+bible.chapter+':'+bible.verse = '$query' $query would equal something like Genesis 1:2, Genesis coming from books.book, 1 coming from bible.chapter and 2 coming from bible.verse Any help/guidance on this is much appreciated =)

• Sending email from Drupal contact form, but GMail marks it as "Forged"

  - by James Shields

  Hi, My Drupal site sends email to a GMail account, but the emails sent all go into the Spam folder, and GMail puts up a bar with the message "This message was likely forged and did not originate from your account." Although I can create a filter to prevent them going to Spam, I want to start sending newsletters, and I suspect they'll have the same problem. I suspect the problem is with the way I've set up either PHP or Drupal to send mail. As far as I know it's just using the sendmail function. I've set the from address to "info@..." where ... is the site domain. Any tips on how I can make set up my outgoing mail so it won't be refused by GMail (and presumably other major mail providers)? Thanks, James

• iPhone: Chained views

  - by Michael

  I want to have dynamically created views and be able to scroll(change views like in camera roll) either from my program or user should also be able to do that. The views should contain only a simple text. Each view has to replace other, so they are like chained. The other example is the screenshots of applications in app store application details. I don't know which classes to check/start so if anyone can give me an idea of how this could be designed I would appreciate it.

• Java Annotations - Is there any helper library to read/process annotations?

  - by mjlee

  I start to use Java annotations heavily. One example is taking method with annotations and converting them into 'telnet'-based command-line command. I do this by parsing annotations and hook into jopt option parser. However, I do a lot of these manually. For example, Method parameter annotation processing.. Method method = ... //; Class[] parameters = method.getParamterTypes(); Annotation[][] annotations = method.getparamterAnnotations(); for( int i = 0; i < parameters.length; i++ ) { // iterate through the annotation , see if each param has specific annotation ,etc. } It is very redundant and tedious. Is there any opensource project that help processing Annotations?

• Is autoload thread-safe in Ruby 1.9?

  - by SFEley

  It seems to me that the Ruby community has been freaking out a little about autoload since this famous thread, discouraging its use for thread safety reasons. Does anyone know if this is no longer an issue in Ruby 1.9.1 or 1.9.2? I've seen a bit of talk about wrapping requires in mutexes and such, but the 1.9 changelogs (or at least as much as I've been able to find) don't seem to address this particular question. I'd like to know if I can reasonably start autoloading in 1.9-only libraries without any reasonable grief. Thanks in advance for any insights.

• Sign Up/Login system for multi-domain/multi-server

  - by David

  I'm thinking about a good solution for implementing a sign up/login system that works across different domains and servers. A working example is Olx (you can register in one domain, and your login will work in the rest of domains). The scenario is that every domain (one per country) has its own database. And there will be 2 servers (for example), each one will have the 50% of the domains (and so the 50% of databases). What would you suggest to start with? Database: MySQL 5.1 Server-side language: PHP 5.3 (I will be using Symfony 1.4, so if someone has some suggestion for this framework, it will be interesting too, although it is optional)

• What's the ROI of using a build tool like ant or nant?

  - by leeand00

  To me this sounds like a really stupid question. Why would you not use a build tool? However, I need to explain my co-worker why he should be using a build tool of some sort. He's getting really into the idea of working as a team with more programmers, but he isn't understanding the bigger picture of what needs to change in the build process in order to work with a larger team; (i.e. defensive programming/unit testing your code, having a bug database, programming modular libraries, and using sub-repositories to store modules in version control. This is a rather large stack of technologies that I need to prove the ROI of...so I figured I'd start with the ROI of using a build tool rather than just...say...clicking compile.
