• How to call split(token) on a string that does not contain the token without causing an error?

  - by Vorinowsky

  I have two types of strings as the IDs of elements in my HTML markup: Dates: "april-23" "march-20" and season names: "springtime" "winter" The dates have a dash separating the month and the day. The seasons are a single word with no other tokens. I want to assign the month or the season to a new variable called: time_of_year If I do this: var time_of_year = $(this).attr("id").split('-')[0]; It will work on the months but if I call it on a season name which does not contain the token, will it generate an error? What's the safe way to do this?

• Month TableView Organizer

  - by rson

  I need to create a table view with 1 or 2 sections, depending on certain conditions. The first section needs to contain all of the remaining months of the current year, and the second section contains the preceding months of the next year, up to but not including the current month. Example: 2009 November December 2010 January February March April May June July August September October This would be the scenario with the current month of November. However, if it were January, there would be only 1 section containing all 12 months of the current year. This all needs to be dependent on the date settings of the phone.

• Building Visual Studio Setup Projects with TFS 2010 Team Build

  - by Jakob Ehn

  One of the most common complaints from people starting to use Team Build is that is doesn’t support building Microsoft’s own Setup and Deployment project (*.vdproj). When creating a default build definition that compiles a solution containing a setup project, you’ll get the following warning: The project file "MyProject.vdproj" is not supported by MSBuild and cannot be built.   This is what the problem is all about. MSBuild, that is used for compiling your projects, does not understand the proprietary vdproj format defined by Microsoft quite some time ago. Unfortunately there is no sign that this will change in the near future, in fact the setup projects has barely changed at all since they were introduced. VS 2010 brings no new features or improvements hen it comes to the setup projects. VS 2010 does include a limited version of InstallShield which promises to be more MSBuild friendly and with more or less the same features as VS setup projects. I hope to get a closer look at this installer project type soon. But, how do we go about to build a Visual Studio setup project and produce an MSI as part of a Team Build process? Well, since only one application known to man understands the vdproj projects, we will have to installa copy of Visual Studio on the build server. Sad but true. After doing this, we use the Visual Studio command line interface (devenv) to perform the build. In this post I will show how to do this by using the InvokeProcess activity directly in a build workflow template. You’ll want to run build your setup projects after you have successfully compiled the projects.   Install Visual Studio 2010 on the build server(s)   Open your build process template /remember to branch or copy the xaml file before modifying it!)   Locate the Try to Compile the Project activity   Drop an instance of the InvokeProcess activity from the toolbox onto the designer, after the Run MSBuild for Project activity   Drop an instance of the WriteBuildMessage activity inside the Handle Standard Output section. Set the Importance property to Microsoft.TeamFoundation.Build.Client.BuildMessageImportance.High (NB: This is necessary if you want the output from devenv to show up in the build log when running the build with the default verbosity) Set the Message property to stdOutput   Drop an instance of the WriteBuildError activity to the Handle Error Output section Set the Message property to errOutput   Select the InvokeProcess activity and set the values of the parameters to:     The finished workflow should look like this:     This will generate the MSI files, but they won’t be copied to the drop location. This is because we are using devenv and not MSBuild, so we have to do this explicitly   Drop a Sequence activity somewhere after the Copy to Drop location activity.   Create a variable in the Sequence activity of type IEnumerable<String> and call it GeneratedInstallers   Drop a FindMatchingFiles activity in the sequence activity and set the properties to:     Drop a ForEach<String> activity after the FindMatchingFiles activity. Set the Value property to GeneratedInstallers   Drop an InvokeProcess activity inside the ForEach activity.  FileName: “xcopy.exe” Arguments: String.Format("""{0}"" ""{1}""", item, BuildDetail.DropLocation) The Sequence activity should look like this:     Save the build process template and check it in.   Run the build and verify that the MSI’s is built and copied to the drop location.   Note 1: One of the drawback of using devenv like this in a team build is that since all the output from the default compilations is placed in the Binaries folder, the outputs is not avaialable when devenv is invoked, which causes the whole solution to rebuild again. In TFS 2008, this was pretty simple to fix by using the CustomizableOutDir property. In TFS 2010, the same feature is not avaialble. Jim Lamb blogged about this recently, have a look at it if you have a problem with this: http://blogs.msdn.com/jimlamb/archive/2010/04/13/customizableoutdir-in-tfs-2010.aspx   Note 2: Although the above solution works, a better approach is to wrap this in a custom activity that you can use in your builds. I will come back to this in a future post.

• They may block off Howard Street—but Oracle OpenWorld is a two-way street.

  - by Oracle Accelerate for Midsize Companies

  Normal 0 false false false EN-US X-NONE X-NONE MicrosoftInternetExplorer4 by Jim Lein, Sr. Director, Oracle Accelerate for Midsize Companies “Engineered to Inform and Inspire”—that’s the theme of Oracle OpenWorld 2012. In early October, tens of thousands of attendees will descend on the streets of San Francisco because they share one thing in common: the desire to learn more about Oracle. You might think that’s the way we, Oracle employees, look at this event—as just another opportunity for attendees to learn about what we do. But it’s really a two way street. Every year I’m amazed by how informed and inspired I am by our customers and their companies. Midsize companies buy Oracle to grow. As part of the Oracle Accelerate for Midsize Companies team I get to talk with our partners and business leaders at growing companies almost every day, usually via phone. Oracle OpenWorld presents the perfect opportunity to meet some of them in person, in an informal setting, and in one of the most beautiful cities in the world. The stories our customers tell me about their businesses provide vivid examples of how they have overcome the challenges of managing increasingly complex global operations and growing during uncertain economic conditions. It’s no secret that my favorite session at Oracle OpenWorld (besides Larry Ellison’s keynotes and the Customer Appreciation Event, of course) is the Oracle Accelerate Customer Panel. This year we’re featuring executives from three companies who deployed Oracle ERP rapidly to support their company’s growth: Chris Powell, VP and Corporate Controller of Beats by Dr. Dre, a California based designer and manufacturer of premium headphones (sorry, no free samples), Iñaki Zuazo, CIO of Industrias Juno, a building materials provider based in Spain, Kamran Moosa, Project Coordinator for Spartan Engineering, a provider of engineering and construction support services for an LPG storage project in Texas, and That’s a pretty diverse lineup and it will be interesting to hear the perspectives of both IT and financial project stakeholders. The session, “Oracle Accelerate Customer Case Studies: Rapid Deployment of Oracle Applications”, is at 3:30 pm on Wednesday, October 3, in the Concert room at the Palace Hotel. Oracle loves our hometown of San Francisco and it’s a great place to host Oracle OpenWorld. It’s now San Francisco’s largest conference and the city closes off Howard Street to better accommodate the attendees. Some Bay Area commuters may be inconvenienced for a few days by this closure but the conference brings about $100 million into the local economy. Now that’s a two-way street.

• Adding Fake Build Information in TFS 2010

  - by Jakob Ehn

  We have been using TFS 2010 build for distributing a build in parallel on several agents, but where the actual compilation is done by a bunch of external tools and compilers, e.g. no MSBuild involved. We are using the ParallelTemplate.xaml template that Jim Lamb blogged about previously, which distributes each configuration to a different agent. We developed custom activities for running these external compilers and collecting the information and errors by reading standard out/error and pushing it back to the build log. But since we aren’t using MSBuild we don’t the get nice configuration summary section on the build summary page that we are used to. We would like to show the result of each configuration with any errors/warnings as usual, together with a link to the log file. TFS 2010 API to the rescue! What we need to do is adding information to the InformationNode structure that is associated with every TFS build. The log that you normally see in the Log view is built up as a tree structure of IBuildInformationNode objects. This structure can we accessed by using the InformationNodeConverters class. This class also contain some helper methods for creating BuildProjectNode, which contain the information about each project that was build, for example which configuration, number of errors and warnings and link to the log file. Here is a code snippet that first creates a “fake” build from scratch and the add two BuildProjectNodes, one for Debug|x86 and one for Release|x86 with some release information:   TfsTeamProjectCollection collection = TfsTeamProjectCollectionFactory.GetTeamProjectCollection(new Uri("http://lt-jakob2010:8080/tfs")); IBuildServer buildServer = collection.GetService<IBuildServer>(); var buildDef = buildServer.GetBuildDefinition("TeamProject", "BuildDefinition"); //Create fake build with random build number var detail = buildDef.CreateManualBuild(new Random().Next().ToString()); // Create Debug|x86 project summary IBuildProjectNode buildProjectNode = detail.Information.AddBuildProjectNode(DateTime.Now, "Debug", "MySolution.sln", "x86", "$/project/MySolution.sln", DateTime.Now, "Default"); buildProjectNode.CompilationErrors = 1; buildProjectNode.CompilationWarnings = 1; buildProjectNode.Node.Children.AddBuildError("Compilation", "File1.cs", 12, 5, "", "Syntax error", DateTime.Now); buildProjectNode.Node.Children.AddBuildWarning("File2.cs", 3, 1, "", "Some warning", DateTime.Now, "Compilation"); buildProjectNode.Node.Children.AddExternalLink("Log File", new Uri(@"\\server\share\logfiledebug.txt")); buildProjectNode.Save(); // Create Releaes|x86 project summary buildProjectNode = detail.Information.AddBuildProjectNode(DateTime.Now, "Release", "MySolution.sln", "x86", "$/project/MySolution.sln", DateTime.Now, "Default"); buildProjectNode.CompilationErrors = 0; buildProjectNode.CompilationWarnings = 0; buildProjectNode.Node.Children.AddExternalLink("Log File", new Uri(@"\\server\share\logfilerelease.txt")); buildProjectNode.Save(); detail.Information.Save(); detail.FinalizeStatus(BuildStatus.Failed); When running this code, it will a create a build that looks like this: As you can see, it created two configurations with error and warning information and a link to a log file. Just like a regular MSBuild would have done. This is very useful when using TFS 2010 Build in heterogeneous environments. It would also be possible to do this when running compilations completely outside TFS build, but then push the results of the into TFS for easy access. You can push all information, including the compilation summary, drop location, test results etc using the API.

• Gamify your Web

  - by Isabel F. Peñuelas

  Yesterday Valencia welcomed the Gamification World Congress that I follow virtually through #GWC2012. BBVA, Iberia, Ligeresa, Axe, Wayra, ESADE, GlaxoSmithKline, Macmillan, Gamisfaction, Nomaders, Blaffin were among the companies presenting success stories on gaming. It has been proved that people remember things easily when an emotion is created. The marketing expectations around Gamification techniques have a lot to do with Neuromarketing theories. There are a lot of expectations on internal enterprise Gamification. In the public Web some sectors are taking the lead on following the trend. The Gartner Analyst Brian Burke opened another Gamification recent event in Madrid remembering that “Gamification is mostly about Engagement”, and this can be applied both to customers or employees. Gamification and Banking The experience of the Spanish Financial Group BBVA that just launched BBVA Game was also presented a week ago at the BBVA Innovation Centre during the event “Gamification & Banking: a fad or a serious business?” . One of the objectives of the BBVA Game was to double the name of registered users. “People like the efficiency of the online channel want to keep a one-to-one contact with the brand”-explained Bernardo Crespo. Another interested data coming out the BBVA presentation was that “only 20% of Spanish users –out of the total holders of Bank Accounts in the country- is familiar with the use of a Web Site to consult their bank accounts”, the project aims also to reverse this situation helping people to learn making a heavy use of the Video in the gaming context. In general Banking presenters seem to agree that Gamification techniques are helping to increase the time spent on the Web. Gamification and Health Using Gamification techniques for chronic illness rehabilitation was another topic of the World Congress. Here you can find some ideas and experiences What can games do for the health (In Spanish) I have personally started my own mental-health gaming project at http://www.lumosity.com/ Gamification in the Enterprise I really recommend Reading this excellent post of Ultan ÓBroin my Introduction to Gamification and Applications. Employee´s motivation and learning are experiencing a 360º turn and it looks than some of us will become soon the Dragon of the year instead of the Employee of the Year. Using Web 2.0 Tools for Gamification Projects  What type of tools do we need for a quick-win Gamification project? To certain extend Gamification can be considered an evolution of the participative Web. Badging, avatars, points and awards, leader boards, progress charts, virtual currencies, gifting and giving challenges and quests are common components and elements. The Web is offering new development frameworks to that purpose as this Avatar Framework from Paypal or Badgeville to include in web applications. Besides, tools to create communities around a game are required to comment, share and vote players as well as for an efficient multimedia management. Due to its entirely open architecture, its community features, and its multimedia and imaging solutions is were I see WebCenter as a tool helping brands to success.

• How can I thoroughly evaluate a prospective employer?

  - by glenviewjeff

  We hear much about code smells, test smells, and even project smells, but I have heard no discussion about employer "smells" outside of the Joel Test. After much frustration working for employers with a bouquet of unpleasant corporate-culture odors, I believe it's time for me to actively seek a more mature development environment. I've started assembling a list of questions to help vet employers by identifying issues during a job interview, and am looking for additional ideas. I suppose this list could easily be modified by an employer to vet an employee as well, but please answer from the interviewee's perspective. I think it would be important to ask many of these questions of multiple people to find out if consistent answers are given. For the most part, I tried to put the questions in each section in the order they could be asked. An undesired answer to an early question will often make follow-ups moot. Values What constitutes "well-written" software? What attributes does a good developer have? Same question for manager. Process Do you have a development process? How rigorously do you follow it? How do you decide how much process to apply to each project? Describe a typical project lifecycle. Ask the following if they don't come up otherwise: Waterfall/iterative: How much time is spent in upfront requirements gathering? upfront design? Testing Who develops tests (developers or separate test engineers?) When are they developed? When are the tests executed? How long do they take to execute? What makes a good test? How do you know you've tested enough? What percentage of code is tested? Review What is the review process like? What percentage of code is reviewed? Design? How frequently can I expect to participate as code/design reviewer/reviewee? What are the criteria applied to review and where do the criteria come from? Improvement What new tools and techniques have you evaluated or deployed in the past year? What training courses have your employees been given in the past year? What will I be doing for the first six months in your company (hinting at what kind of organized mentorship/training has been thought through, if any) What changes to your development process have been made in the past year? How do you improve and learn from your mistakes as an organization? What was your organizations biggest mistake in the past year, and how was it addressed? What feedback have you given to management lately? Was it implemented? If not, why? How does your company use "best practices?" How do you seek them out from the outside or within, and how do you share them with each other? Ethics Tell me about an ethical problem you or your employees experienced recently and how was it resolved? Do you use open-source software? What open-source contributions have you made? Follow-Ups I liked what @jim-leonardo said on this Stack Overflow question: Really a thing to ask yourself: "Does this person seem like they are trying to recruit me and make me interested?" I think this is one of the most important bits. If they seem to be taking the attitude that the only one being interviewed is you, then they probably will treat you poorly. Good interviewers understand they have to sell the position as much as the candidate needs to sell themselves. @SethP added: Glassdoor.com is a good web site for researching potential employers.

• JavaOne Latin America 2012 Trip Report

  - by reza_rahman

  JavaOne Latin America 2012 was held at the Transamerica Expo Center in Sao Paulo, Brazil on December 4-6. The conference was a resounding success with a great vibe, excellent technical content and numerous world class speakers. Some notable local and international speakers included Bruno Souza, Yara Senger, Mattias Karlsson, Vinicius Senger, Heather Vancura, Tori Wieldt, Arun Gupta, Jim Weaver, Stephen Chin, Simon Ritter and Henrik Stahl. Topics covered included the JCP/JUGs, Java SE 7, HTML 5/WebSocket, CDI, Java EE 6, Java EE 7, JSF 2.2, JMS 2, JAX-RS 2, Arquillian and JavaFX. Bruno Borges and I manned the GlassFish booth at the Java Pavilion on Tuesday and Webnesday. The booth traffic was decent and not too hectic. We met a number of GlassFish adopters including perhaps one of the largest GlassFish deployments in Brazil as well as some folks migrating to Java EE from Spring. We invited them to share their stories with us. We also talked with some key members of the local Java community. Tuesday evening we had the GlassFish party at the Tribeca Pub. The party was definitely a hit and we could have used a larger venue (this was the first time we had the GlassFish party in Brazil). Along with GlassFish enthusiasts, a number of Java community leaders were there. We met some of the same folks again at the JUG leader's party on Wednesday evening. On Thursday Arun Gupta, Bruno Borges and I ran a hands-on-lab on JAX-RS, WebSocket and Server-Sent Events (SSE) titled "Developing JAX-RS Web Applications Utilizing Server-Sent Events and WebSocket". This is the same Java EE 7 lab run at JavaOne San Francisco. The lab provides developers a first hand glipse of how an HTML 5 powered Java EE application might look like. We had an overflow crowd for the lab (at one point we had about twenty people standing) and the lab went very well. The slides for the lab are here: Developing JAX-RS Web Applications Utilizing Server-Sent Events and WebSocket from Reza Rahman The actual contents for the lab is available here. Give me a shout if you need help getting it up and running. I gave two solo talks following the lab. The first was on JMS 2 titled "What’s New in Java Message Service 2". This was essentially the same talk given by JMS 2 specification lead Nigel Deakin at JavaOne San Francisco. I talked about the JMS 2 simplified API, JMSContext injection, delivery delays, asynchronous send, JMS resource definition in Java EE 7, standardized configuration for JMS MDBs in EJB 3.2, mandatory JCA pluggability and the like. The session went very well, there was good Q & A and someone even told me this was the best session of the conference! The slides for the talk are here: What’s New in Java Message Service 2 from Reza Rahman My last talk for the conference was on JAX-RS 2 in the keynote hall. Titled "JAX-RS 2: New and Noteworthy in the RESTful Web Services API" this was basically the same talk given by the specification leads Santiago Pericas-Geertsen and Marek Potociar at JavaOne San Francisco. I talked about the JAX-RS 2 client API, asyncronous processing, filters/interceptors, hypermedia support, server-side content negotiation and the like. The talk went very well and I got a few very kind complements afterwards. The slides for the talk are here: JAX-RS 2: New and Noteworthy in the RESTful Web Services API from Reza Rahman On a more personal note, Sao Paulo has always had a special place in my heart as the incubating city for Sepultura and Soulfy -- two of my most favorite heavy metal musical groups of all time! Consequently, the city has a perpertually alive and kicking metal scene pretty much any given day of the week. This time I got to check out a solid performance by local metal gig Republica at the legendary Manifesto Bar. I also wanted to see a Dio Tribute at the Blackmore but ran out of time and energy... Overall I enjoyed the conference/Sao Paulo and look forward to going to Brazil again next year!

• JavaOne 2012: Nashorn Edition

  - by $utils.escapeXML($entry.author)

  As with my JavaOne 2012: OpenJDK Edition post a while back (now updated to reflect the schedule of the talks), I find it convenient to have my JavaOne schedule ordered by subjects of interest. Beside OpenJDK in all its flavors, another subject I find very exciting is Nashorn. I blogged about the various material on Nashorn in the past, and we interviewed Jim Laskey, the Project Lead on Project Nashorn in the Java Spotlight podcast. So without further ado, here are the JavaOne 2012 talks and BOFs with Nashorn in their title, or abstract:CON5390 - Nashorn: Optimizing JavaScript and Dynamic Language Execution on the JVM - Monday, Oct 1, 8:30 AM - 9:30 AMThere are many implementations of JavaScript, meant to run either on the JVM or standalone as native code. Both approaches have their respective pros and cons. The Oracle Nashorn JavaScript project is based on the former approach. This presentation goes through the performance work that has gone on in Oracle’s Nashorn JavaScript project to date in order to make JavaScript-to-bytecode generation for execution on the JVM feasible. It shows that the new invoke dynamic bytecode gets us part of the way there but may not quite be enough. What other tricks did the Nashorn project use? The presentation also discusses future directions for increased performance for dynamic languages on the JVM, covering proposed enhancements to both the JVM itself and to the bytecode compiler.CON4082 - Nashorn: JavaScript on the JVM - Monday, Oct 1, 3:00 PM - 4:00 PMThe JavaScript programming language has been experiencing a renaissance of late, driven by the interest in HTML5. Nashorn is a JavaScript engine implemented fully in Java on the JVM. It is based on the Da Vinci Machine (JSR 292) and will be available with JDK 8. This session describes the goals of Project Nashorn, gives a top-level view of how it all works, provides the current status, and demonstrates examples of JavaScript and Java working together.BOF4763 - Meet the Nashorn JavaScript Team - Tuesday, Oct 2, 4:30 PM - 5:15 PMCome to this session to meet the Oracle JavaScript (Project Nashorn) language teamBOF6661 - Nashorn, Node, and Java Persistence - Tuesday, Oct 2, 5:30 PM - 6:15 PMWith Project Nashorn, developers will have a full and modern JavaScript engine available on the JVM. In addition, they will have support for running Node applications with Node.jar. This unique combination of capabilities opens the door for best-of-breed applications combining Node with Java SE and Java EE. In this session, you’ll learn about Node.jar and how it can be combined with Java EE components such as EclipseLink JPA for rich Java persistence. You’ll also hear about all of Node.jar’s mapping, caching, querying, performance, and scaling features.CON10657 - The Polyglot Java VM and Java Middleware - Thursday, Oct 4, 12:30 PM - 1:30 PMIn this session, Red Hat and Oracle discuss the impact of polyglot programming from their own unique perspectives, examining non-Java languages that utilize Oracle’s Java HotSpot VM. You’ll hear a discussion of topics relating to Ruby, Lisp, and Clojure and the intersection of other languages where they may touch upon individual frameworks and projects, and you’ll get perspectives on JavaScript via the Nashorn Project, an upcoming JavaScript engine, developed fully in Java.CON5251 - Putting the Metaobject Protocol to Work: Nashorn’s Java Bindings - Thursday, Oct 4, 2:00 PM - 3:00 PMProject Nashorn is Oracle’s new JavaScript runtime in Java 8. Being a JavaScript runtime running on the JVM, it provides integration with the underlying runtime by enabling JavaScript objects to manipulate Java objects, implement Java interfaces, and extend Java classes. Nashorn is invokedynamic-based, and for its Java integration, it does away with the concept of wrapper objects in favor of direct virtual machine linking to Java objects’ methods provided by a metaobject protocol, providing much higher performance than what could be expected from a scripting runtime. This session looks at the details of the integration, a topic of interest to other language implementers on the JVM and a wider audience of developers who want to understand how Nashorn works.That's 6 sessions tooting the Nashorn this year at JavaOne, up from 2 last year.

• Read large file into sqlite table in objective-C on iPhone

  - by James Testa

  I have a 2 MB file, not too large, that I'd like to put into an sqlite database so that I can search it. There are about 30K entries that are in CSV format, with six fields per line. My understanding is that sqlite on the iPhone can handle a database of this size. I have taken a few approaches but they have all been slow 30 s. I've tried: 1) Using C code to read the file and parse the fields into arrays. 2) Using the following Objective-C code to parse the file and put it into directly into the sqlite database: NSString *file_text = [NSString stringWithContentsOfFile: filePath usedEncoding: NULL error: NULL]; NSArray *lineArray = [file_text componentsSeparatedByString:@"\n"]; for(int k = 0; k < [lineArray count]; k++){ NSArray *parts = [[lineArray objectAtIndex:k] componentsSeparatedByString: @","]; NSString *field0 = [parts objectAtIndex:0]; NSString *field2 = [parts objectAtIndex:2]; NSString *field3 = [parts objectAtIndex:3]; NSString *loadSQLi = [[NSString alloc] initWithFormat: @"INSERT INTO TABLE (TABLE, FIELD0, FIELD2, FIELD3) VALUES ('%@', '%@', '%@');",field0, field2, field3]; if (sqlite3_exec (db_table, [loadSQLi UTF8String], NULL, NULL, &errorMsg) != SQLITE_OK) { sqlite3_close(db_table); NSAssert1(0, @"Error loading table: %s", errorMsg); } Am I missing something? Does anyone know of a fast way to get the file into a database? Or is it possible to translate the file into a sqlite format that can be read directly into sqlite? Or should I turn the file into a plist and load it into a Dictionary? Unfortunately I need to search on two of the fields, and I think a Dictionary can only have one key? Jim

• Why can't I get a TRUE return in this prepared statement?

  - by Cortopasta

  I can't seem to get this to do anything but return false. My best guess is that the prepared statement isn't executing, but I have no idea why. private function check_credentials($plain_username, $md5_password) { global $dbcon; $ac = new ac(); $ac->dbconnect(); $userid = $dbcon->prepare('SELECT id FROM users WHERE username = :username AND password = :password LIMIT 1'); $userid->bindParam(':username', $plain_username); $userid->bindParam(':password', $md5_password); $userid->execute(); $id = $userid->fetch(); Return $id; } *EDIT:*I've even tried hard coding the username and password into the function itself to try and isolate the problem like this: private function check_credentials($plain_username, $md5_password) { global $dbcon; $plain_username = "jim"; $md5_username = "waffles"; $ac = new ac(); $ac->dbconnect(); $userid = $dbcon->prepare('SELECT id FROM users WHERE username = :username AND password = :password LIMIT 1'); $userid->bindParam(':username', $plain_username); $userid->bindParam(':password', $md5_password); $userid->execute(); print_r($dbcon->errorInfo()); $id = $userid->fetch(); Return $id; } Still nothing :-/

• Can I create template-based library objects in Dreamweaver CS5?

  - by Danjah

  At work we need two 'streams' of template. The first are general layout templates, like the ones already available in the MX through CS5 packages (except we'd have our own customised ones). The second are more granular objects, some of which are functional. In both cases, I don't want Jimmy to be able to wreak havoc inside anything other than the 'editable regions' which make up the templates. Now this is fine if I stick with the first scenario (layout templates) where there's simply a big chunk of editable region for good ole Jim to sprawl into, think of this as the 'body content' area. But I really do need these granular library (or snippet) objects to work in the same way. Unfortunately with my attempts so far they don't work as I'd have thought - perhaps for good reason? When I create a blank template and throw in my chunk of HTML (unobstrusive JS and external CSS use selectors in this HTML to provide style and function) and save it as a new library item or snippet, all looks well. Then I create a new document based on a layout template and save it as a plain html file (still all good so far). Next I drop in my custom library item... still all good... but then I go to save the document and it only allows me to save it as a new template! I expected it would just allow me to save it as HTML and have it simply respect the defined editable regions, as happens in the containing page 'body content' editable region. Apologies if that got specific and technical quite quickly, but it is quite particular. If you want some example files lemme know and I'll zip some up. Many thanks :) p.s It is not a requirement that library objects must somehow inject their dependency files into the newly created page - I already know what they'll be. Also, I know I must 'detatch from original' once I drop a library item into a document which then allows customisation of the library object.

• Why did this work with Visual C++, but not with gcc?

  - by Carlos Nunez

  I've been working on a senior project for the last several months now, and a major sticking point in our team's development process has been dealing wtih rifts between Visual-C++ and gcc. (Yes, I know we all should have had the same development environment.) Things are about finished up at this point, but I ran into a moderate bug just today that had me wondering whether Visual-C++ is easier on newbies (like me) by design. In one of my headers, there is a function that relies on strtok to chop up a string, do some comparisons and return a string with a similar format. It works a little something like the following: int main() { string a, b, c; //Do stuff with a and b. c = get_string(a,b); } string get_string(string a, string b) { const char * a_ch, b_ch; a_ch = strtok(a.c_str(),","); b_ch = strtok(b.c_str(),","); } strtok is infamous for being great at tokenizing, but equally great at destroying the original string to be tokenized. Thus, when I compiled this with gcc and tried to do anything with a or b, I got unexpected behavior, since the separator used was completely removed in the string. Here's an example in case I'm unclear; if I set a = "Jim,Bob,Mary" and b="Grace,Soo,Hyun", they would be defined as a="JimBobMary" and b="GraceSooHyun" instead of staying the same like I wanted. However, when I compiled this under Visual C++, I got back the original strings and the program executed fine. I tried dynamically allocating memory to the strings and copying them the "standard" way, but the only way that worked was using malloc() and free(), which I hear is discouraged in C++. While I'm curious about that, the real question I have is this: Why did the program work when compiled in VC++, but not with gcc? (This is one of many conflicts that I experienced while trying to make the code cross-platform.) Thanks in advance! -Carlos Nunez

• what exactly is the danger of an uninitialized pointer in C

  - by akh2103

  I am trying get a handle on C as I work my way thru Jim Trevor's "Cyclone: A safe dialect of C" for a PL class. Trevor and his co-authors are trying to make a safe version of C, so they eliminate uninitialized pointers in their language. Googling around a bit on uninitialized pointers, it seems like un-initialized pointers point to random locations in memory. It seems like this alone makes them unsafe. If you reference an un-itilialized pointer, you jump to an unsafe part of memory. Period. But the way Trevor talks about them seems to imply that it is more complex. He cites the following code, and explains that when the function FrmGetObjectIndex dereferences f, it isn’t accessing a valid pointer, but rather an unpredictable address — whatever was on the stack when the space for f was allocated. What does Trevor mean by "whatever was on the stack when the space for f was allocated"? Are "un-initialized" pointers initialized to random locations in memory by default? Or does their "random" behavior have to do with the memory allocated for these pointers getting filled with strange values (that are then referenced) because of unexpected behavior on the stack. Form *f; switch (event->eType) { case frmOpenEvent: f = FrmGetActiveForm(); ... case ctlSelectEvent: i = FrmGetObjectIndex(f, field); ... }

• Virgin STI Help

  - by Mutuelinvestor

  I am working on a horse racing application and I'm trying to utilize STI to model a horse's connections. A horse's connections is comprised of his owner, trainer and jockey. Over time, connections can change for a variety of reasons: The horse is sold to another owner The owner switches trainers or jockey The horse is claimed by a new owner As it stands now, I have model this with the following tables: horses connections (join table) stakeholders (stakeholder has three sub classes: jockey, trainer & owner) Here are my clases and associations: class Horse < ActiveRecord::Base has_one :connection has_one :owner_stakeholder, :through => :connection has_one :jockey_stakeholder, :through => :connection has_one :trainer_stakeholder, :through => :connection end class Connection < ActiveRecord::Base belongs_to :horse belongs_to :owner_stakeholder belongs_to :jockey_stakeholder belongs_to :trainer_stakeholder end class Stakeholder < ActiveRecord::Base has_many :connections has_many :horses, :through => :connections end class Owner < Stakeholder # Owner specific code goes here. end class Jockey < Stakeholder # Jockey specific code goes here. end class Trainer < Stakeholder # Trainer specific code goes here. end One the database end, I have inserted a Type column in the connections table. Have I modeled this correctly. Is there a better/more elegant approach. Thanks in advance for you feedback. Jim

• Select * from 'many to many' SQL relationship

  - by Rampant Creative Group

  I'm still learning SQL and my brain is having a hard time with this one. Say I have 3 tables: teams players and teams_players as my link table All I want to do is run a query to get each team and the players on them. I tried this: SELECT * FROM teams INNER JOIN teams_players ON teams.id = teams_players.team_id INNER JOIN players ON teams_players.player_id = players.id But it returned a separate row for each player on each team. Is JOIN the right way to do it or should I be doing something else? ----------------------------------------- Edit Ok, so from what I'm hearing, this isn't necessarily a bad way to do it. I'll just have to group the data by team while I'm doing my loop. I have not yet tried the modified SQL statements provided, but I will today and get back to you. To answer the question about structure - I guess I wasn't thinking about the returned row structure which is part of what lead to my confusion. In this particular case, each team is limited to 4 players (or less) so I guess the structure that would be helpful to me is something like the following: teams.id, teams.name, players.id, players.name, players.id, players.name, players.id, players.name, players.id, players.name, 1 Team ABC 1 Jim 2 Bob 3 Ned 4 Roy 2 Team XYZ 2 Bob 3 Ned 5 Ralph 6 Tom

• Have to login twice. PHP sessions and login troubles with Chrome and Opera.

  - by Robert

  The problem I am encountering is that for my login form I have to login twice for the session to register properly, but only in Chrome (my version is 4.0.249.89) and Opera (my version is 10.10). Here is the stripped down code that I am testing on: Login Page: session_start(); $_SESSION['user_id'] = 8; $_SESSION['user_name'] = 'Jim'; session_write_close(); header('Location: http://www.my-domain-name.com/'); exit(); Home Page: session_start(); if ( isset($_SESSION['user_id']) ) { echo "You are logged in!"; } else { echo "You are NOT logged in!"; } Logout Page: session_start(); session_unset(); session_destroy(); header('Location: http://www.my-domain-name.com/'); exit(); Currently, under a fresh load with no cookies, if I go to my-domain-name.com/login/ it will redirect to the home page and say "You are NOT logged in!" but if I go there again it will say "You are logged in!". Any ideas? Thanks for your help.
