  • Problem with final branch in a parallel activity

    - by Dan Revell
    This might seem like a silly thing to say, the final branch in a parallel activity so I'll clarify. It's a parallel activity with three branches each containing a simple create task, on task changed and complete task. The branch containing the task that is last to complete seems to break. So every task works in it's own right, but the last one encounters a problem. Say the user clicks the final tasks link to open the attached infopath form and submits that. Execution gets to the event handler for that onTaskChanged where a taskCompleted variable gets set to true which will exit the while loop. I've successfully hit a breakpoint on this line so I know that happens. However the final activity in that branch, the completeTask doesn't get hit. When submit is clicked in the final form, the operation in progess screen says of for quite a while before returning to the workflow status page. The task that was opened and submitted says "Not Started". I can disable any of the branches to leave only two, but the same problem happens with the last to be completed. Earlier on in the workflow I do essencially the same thing. I have another 3 branch parallel activity with each brach containing a task. This one works correctly which leads me to believe that it might be a problem with having two parallel activites in the same sequential workflow. I've considered the possibility that it might be a correlation token problem. The token that every task branch uses is unique to that branch and it's owner activity name is est to that of the branch. It stands to reason that if the task complete variable is indeed getting set to true but the while loop isn't being exited, then there's a wire crossing with the variable somewhere. However I'd still have thought that the task status back on the workflow status page would at least say that the task is in progress. This is a frustrating show stopper of a bug for me. Any thoughts or suggestions would be much appricated so I can investigate them.

  • Qt vs .NET - a few comparisons [closed]

    - by Pirate for Profit
    Event Handling In Qt the event handling system you just emit signals when something cool happens and then catch them in slots, for instance emit valueChanged(int percent, bool something); and void MyCatcherObj::valueChanged(int p, bool ok){} blocking them and disconnecting them when needed, doing it across threads... once you get the hang of it, it just seems a lot more natural and intuitive than the way the .NET event handling is set up (you know, object sender, CustomEventArgs e). And I'm not just talking about syntax, because in the end the .NET delegate crap is the bomb. I'm also talking about in more than just reflection (because, yes, .NET obviously has much stronger reflection capabilities). I'm talking about in the way the system feels to a human being. Qt wins hands down i m o. Basically, the footprints make more sense and you can visualize the project easier without the clunky event handling system. I wish I could it explain it better. The only thing is, I do love some of the ease of C# compared to C++ and .NET's assembly architecture. That is a big bonus for modular projects, which are a PITA to do in C++. Database Ease of Doing Crap Also what about datasets and database manipulations. I think .net wins here but I'm not sure. Threading/Conccurency How do you guys think of the threading? In .NET, all I've ever done is make like a list of master worker threads with locks. I like QConcurrentFramework, you don't worry about locks or anything, and with the ease of the signal slot system across threads it's nice to get notified about the progress of things. Memory Usage Also what do you think of the overall memory usage comparison. Is the .NET garbage collector pretty on the ball and quick compared to the instantaneous nature of native memory management? Or does it just let programs leak up a storm and lag the computer then clean it up when it's about to really lag? However, I am a n00b who doesn't know what I'm talking about, please school me on the subject.

  • How to build an offline web app using Flask?

    - by Rafael Alencar
    I'm prototyping an idea for a website that will use the HTML5 offline application cache for certain purposes. The website will be built with Python and Flask and that's where my main problem comes from: I'm working with those two for the first time, so I'm having a hard time getting the manifest file to work as expected. The issue is that I'm getting 404's from the static files included in the manifest file. The manifest itself seems to be downloaded correctly, but the files that it points to are not. This is what is spit out in the console when loading the page: Creating Application Cache with manifest http://127.0.0.1:5000/static/manifest.appcache offline-app:1 Application Cache Checking event offline-app:1 Application Cache Downloading event offline-app:1 Application Cache Progress event (0 of 2) http://127.0.0.1:5000/style.css offline-app:1 Application Cache Error event: Resource fetch failed (404) http://127.0.0.1:5000/style.css The error is in the last line. When the appcache fails even once, it stops the process completely and the offline cache doesn't work. This is how my files are structured: sandbox offline-app offline-app.py static manifest.appcache script.js style.css templates offline-app.html This is the content of offline-app.py: from flask import Flask, render_template app = Flask(__name__) @app.route('/offline-app') def offline_app(): return render_template('offline-app.html') if __name__ == '__main__': app.run(host='0.0.0.0', debug=True) This is what I have in offline-app.html: <!DOCTYPE html> <html manifest="{{ url_for('static', filename='manifest.appcache') }}"> <head> <title>Offline App Sandbox - main page</title> </head> <body> <h1>Welcome to the main page for the Offline App Sandbox!</h1> <p>Some placeholder text</p> </body> </html> This is my manifest.appcache file: CACHE MANIFEST /style.css /script.js I've tried having the manifest file in all different ways I could think of: CACHE MANIFEST /static/style.css /static/script.js or CACHE MANIFEST /offline-app/static/style.css /offline-app/static/script.js None of these worked. The same error was returned every time. I'm certain the issue here is how the server is serving up the files listed in the manifest. Those files are probably being looked up in the wrong place, I guess. I either should place them somewhere else or I need something different in the cache manifest, but I have no idea what. I couldn't find anything online about having HTML5 offline applications with Flask. Is anyone able to help me out?

  • Workflow for statistical analysis and report writing

    - by ws
    Does anyone have any wisdom on workflows for data analysis related to custom report writing? The use-case is basically this: Client commissions a report that uses data analysis, e.g. a population estimate and related maps for a water district. The analyst downloads some data, munges the data and saves the result (e.g. adding a column for population per unit, or subsetting the data based on district boundaries). The analyst analyzes the data created in (2), gets close to her goal, but sees that needs more data and so goes back to (1). Rinse repeat until the tables and graphics meet QA/QC and satisfy the client. Write report incorporating tables and graphics. Next year, the happy client comes back and wants an update. This should be as simple as updating the upstream data by a new download (e.g. get the building permits from the last year), and pressing a "RECALCULATE" button, unless specifications change. At the moment, I just start a directory and ad-hoc it the best I can. I would like a more systematic approach, so I am hoping someone has figured this out... I use a mix of spreadsheets, SQL, ARCGIS, R, and Unix tools. Thanks! PS: Below is a basic Makefile that checks for dependencies on various intermediate datasets (w/ ".RData" suffix) and scripts (".R" suffix). Make uses timestamps to check dependencies, so if you 'touch ss07por.csv', it will see that this file is newer than all the files / targets that depend on it, and execute the given scripts in order to update them accordingly. This is still a work in progress, including a step for putting into SQL database, and a step for a templating language like sweave. Note that Make relies on tabs in its syntax, so read the manual before cutting and pasting. Enjoy and give feedback! http://www.gnu.org/software/make/manual/html%5Fnode/index.html#Top R=/home/wsprague/R-2.9.2/bin/R persondata.RData : ImportData.R ../../DATA/ss07por.csv Functions.R $R --slave -f ImportData.R persondata.Munged.RData : MungeData.R persondata.RData Functions.R $R --slave -f MungeData.R report.txt: TabulateAndGraph.R persondata.Munged.RData Functions.R $R --slave -f TabulateAndGraph.R report.txt

  • How to limit results in a SharePoint XSL query

    - by David
    Hello all, I am creating a SharePoint site that we will use to report issues with trucks used in our business. Linked to the list I have created will be a page that will display an overview of the trucks and a little truck icon will show the trucks current status. Green and the truck is okay (no open issues), Red and the truck have an open issue with status "Undrivable", Orange and there is two issues open that requires the user to look further into the truck before using it and finally a Gray truck for when there is a new issue created that has not been looked into (not sure if it is drivable or not). I have managed to create the "Dashboard" and with my limit XSL/XPATH knowledge been able to add a truck and replicate the description above but... in my test I have created 4 issues, for example if three of them are changed to status Closed and one left to Undrivable I will get four icons on the page, three with Green trucks and the last one Red. So in theory it works but I obviously only want to see the last truck, one truck. I am not interested in seeing the others. <xsl:template name="dvt_1.rowview"> <xsl:variable name="CountReport" select="count(/dsQueryResponse/Rows/Row[@Highloader='GGEU12' and @Status!='Closed'])" /> <xsl:variable name="MoreThan" select="$CountReport &gt; 1" /> <xsl:variable name="NoReports" select="$CountReport = 0" /> <xsl:variable name="Closed" select=" @Highloader='GGEU12' and @Status='Closed'" /> <xsl:choose> <xsl:when test="$MoreThan"> <div class="ms-vb"><img title='More than one report exist!' border='0' alt='In Progress' src='highloader/Library/hl-orange.png' /></div> </xsl:when> <xsl:otherwise> <div class="ms-vb"><xsl:value-of disable-output-escaping="yes" select="@Icon" /></div> </xsl:otherwise> </xsl:choose> </xsl:template> My hope is that someone with slightly more knowledge can find the last piece of the puzzle for me! Thanks for reading and asking questions to fill any gap I left above. David

  • c++ exceptions and program execution logic

    - by Andrew
    Hello everyone, I have been thru a few questions but did not find an answer. I wonder how should the exception handling be implemented in a C++ software so it is centralized and it is tracking the software progress? For example, I want to process exceptions at four stages of the program and know that exception happened at that specific stage: 1. Initialization 2. Script processing 3. Computation 4. Wrap-up. At this point, I tried this: int main (...) { ... // start logging system try { ... } catch (exception &e) { cerr << "Error: " << e.what() << endl; cerr << "Could not start the logging system. Application terminated!\n"; return -1; } catch(...) { cerr << "Unknown error occured.\n"; cerr << "Could not start the logging system. Application terminated!\n"; return -2; } // open script file and acquire data try { ... } catch (exception &e) { cerr << "Error: " << e.what() << endl; cerr << "Could not acquire input parameters. Application terminated!\n"; return -1; } catch(...) { cerr << "Unknown error occured.\n"; cerr << "Could not acquire input parameters. Application terminated!\n"; return -2; } // computation try { ... } ... This is definitely not centralized and seems stupid. Or maybe it is not a good concept at all?

  • Feeding PDF through IInternetSession to WebBrowser control - Error

    - by Codesleuth
    As related to my previous question, I have developed a temporary asynchronous pluggable protocol with the specific aim to be able to serve PDF documents directly to a WebBrowser control via a database. I need to do this because my limitations include not being able to access the disk other than IsolatedStorage; and a MemoryStream would be far better for serving up PDF documents that average around 31kb. Unfortunately the code doesn't work, and I'm getting an error from the WebBrowser control (i.e. IE): Unable to download . Unable to open this Internet site. The requested site is either unavailable or cannot be found. Please try again later. The line in my code where this occurs is within the following: pOIProtSink.ReportData(BSCF.BSCF_LASTDATANOTIFICATION, (uint)_stream.Length, (uint)_stream.Length); However, if you download the project and run it, you will be able to see the stream is successfully read and passed to the browser, so it seems like there's a problem somewhere to do with the end of reading the data: public uint Read(IntPtr pv, uint cb, out uint pcbRead) { var bytesToRead = Math.Min(cb, _streamBuffer.Length); pcbRead = (uint)_stream.Read(_streamBuffer, 0, (int)bytesToRead); Marshal.Copy(_streamBuffer, 0, pv, (int)pcbRead); return (pcbRead == 0 || pcbRead < cb) ? HRESULT.S_FALSE : HRESULT.S_OK; } Here is the entire sample project: InternetSessionSample.zip (VS2010) I will leave this up for as long as I can to help other people in the future If anyone has any ideas why I might be getting this message and can shed some light on the problem, I would be grateful for the assistance. EDIT: A friend suggested inserting a line that calls the IInternetProtocolSink.ReportProgress with BINDSTATUS_CACHEFILENAMEAVAILABLE pointing at the original file. This prevents it from failing now and shows the PDF in the Adobe Reader control, but means it defeats the purpose of this by having Adobe Reader simply load from the cache file (which I can't provide). See below: pOIProtSink.ReportProgress(BINDSTATUS.BINDSTATUS_CACHEFILENAMEAVAILABLE, @"D:\Visual Studio Solutions\Projects\InternetSessionSample\bin\Debug\sample.pdf"); pOIProtSink.ReportData(BSCF.BSCF_LASTDATANOTIFICATION, (uint)_stream.Length, (uint)_stream.Length); This is progress though, I guess.

  • Crashes in Core Data's Inferred Mapping Model Creation (Lightweight Migration). Threading Issue?

    - by enchilada
    I'm getting random crashes when creating an inferred mapping model (with Core Data's lightweight migration) within my application. By the way, I have to do it programmatically in my application while it is running. This is how I create this model (after I have made proper currentModel and newModel objects, of course): NSMappingModel *mappingModel = [NSMappingModel inferredMappingModelForSourceModel:currentModel destinationModel:newModel error:&error]; The problem is this: This method is crashing randomly. When it works, it works just fine without issues. But when it crashes, it crashes my application (instead of returning nil to signify that the method failed, as it should). By randomly, I mean that sometimes it happens and sometimes not. It is unpredictable. Now, here is the deal: I'm running this method in another thread. More precisely, it is located inside a block that is passed via GCD to run on the global main queue. I need to do this for my UI to appear crisp to the user, i.e. so that I can display a progress indicator while the work is underway. The strange thing seems to be that if I remove the GCD stuff and just let it run on the main thread, it seems to be working fine and never crashing. Thus, could it be because I'm running this on a different thread that this is crashing? I somehow find that weird because I don't believe I'm breaking any Core Data rules regarding multi-threading. In particular, I'm not passing any managed objects around, and whenever I need access to the MOC, I create a new MOC, i.e. I'm not relying on any MOC (or for that matter: anything) that has been created earlier on the main thread. Besides the little MOC stuff that occurs, occurs after the mapping model creation method, i.e. after the point at which the app crashes, so it can't possibly be a cause of the crashes under consideration here. All I'm doing is taking two MOMs and asking for a mapping model between them. That can't be wrong even under threading, now can it? Any ideas on what could be going on?

  • What is the best way, if possible, to send information from a Java PrintStream to a JTextPane?

    - by Daniel Reeves
    In Java, I have a package that translates XML metadata from one standard to another. This package is ultimately accessed through a single function and sends all of its output through a PrintStream object. The output sent is just a status of each file and whether or not it was translated. This is pretty fine and dandy if I'm just printing to System.out, but I'm actually wanting to print this to a JTextPane while it translates (kind of like a progress text box). It wouldn't be a big deal to just print the status after it was done translating the XML, but since there may be thousands of XML files, that's just not feasible. One thing that I've tried is to use a thread that takes all of the information from the PrintStream (which is attached to a ByteArrayOutputStream) and let it send any new information to the text pane. Unfortunately, this still sends the information all at once at the end of the translation. This does work correctly for System.out. Here's the code that does the translation and tries to show the output: public class ConverterGUI extends javax.swing.JFrame { boolean printToResultsBox = false; PrintStream printStream = null; ByteArrayOutputStream baos = null; private class ResultsPrinter implements Runnable { public ResultsPrinter() { baos = new ByteArrayOutputStream(); printStream = new PrintStream(baos); } public void run() { String tempString = ""; while (printToResultsBox) { try { if (!baos.toString().equals(tempString)) { tempString = baos.toString(); resultsBox.setText(tempString); } } catch (Exception ex) { } } } } ... ResultsPrinter rp = new ResultsPrinter(); Thread thread = new Thread(rp); thread.start(); // Do the translation. try { printToResultsBox = true; boolean success = false; TranslationEngine te = new TranslationEngine(); // fileOrFolderToConvert is a text box in the GUI. // linkNeeded and destinationFile are just parameters for the translation process. success = te.translate(fileOrFolderToConvert.getText(), linkNeeded, destinationFile, printStream); if (success) { printStream.println("File/folder translation was a success."); } resultsBox.setText(baos.toString()); } catch (Exception ex) { printStream.println("File translation failed."); } finally { printToResultsBox = false; } ... } Ultimately, this code prints out to the JTextPane just fine after all the translation is done but not during. Any suggestions? Do I need to change the PrintStream to something else?

  • HTML5 Video Tag in Chrome - Why is currentTime ignored when video downloaded from my webserver?

    - by larson4
    I want to be able to play back video from a specific time using the HTML5 video tag (and currently only need to worry about Chrome). This is possible by setting the currentTime property of a video element. That works fine in Chrome with a video sourced from html5rocks.com, but is ignored when the same file is loaded from my own local webserver. Using the sample code from http://playground.html5rocks.com/#video_tag, I have arrived at the following HTML: <!DOCTYPE html> <html> <body> <video id="video1" width="320" height="240" volume=".7" controls preload=true autobuffer> <source src="http://playground.html5rocks.com/samples/html5_misc/chrome_japan.webm" type='video/webm; codecs="vp8, vorbis"'/> </video> <input type=button onclick="play()" value="play"> <input type=button onclick="setTime()" value="setTime"> <input type=button onclick="pause()" value="pause"> <script> var play=function() { document.getElementById("video1").play(); } var setTime=function() { document.getElementById("video1").currentTime=2; } var pause=function() { document.getElementById("video1").pause(); } </script> </body> </html> Using Chrome, if you Wait for the video to download for a bit (until the progress bar is about 10% in) Press setTime - you should notice the time jump to 2 seconds press play ...the video will start at 2 seconds in. But if I download the webm file in the source src to my local webserver, and change src to point locally: <source src="chrome_japan.webm" type='video/webm; codecs="vp8, vorbis"'/> ...then setting currentTime is complete ignored. No errors are showing in the developer tools console. Now, my webserver is serving this with mime type "video/webm", but it will be served like any old file -- not streamed. Do I need a webserver that streams in some specific way? What else could be at fault here? Note: The webserver is a proprietary platform and won't have any of the same exact settings or controls one might expect of Tomcat or some other commonly used webserver, though there may be other ways to achieve the same effect.

  • How to have combobox take data from a child datasource

    - by SkollSunman
    I am trying to have a datagridview with two comboboxes, a company name and a supplier account number. When a company name is selected the relevant supplier account numbers (a company can have more than one supplier account) should be filtered for that company in that row. I have a datagridview with two bindingsources: supplierBindingSource and companyBindingSource and the Supplier account combobox uses the supplierBindingSource for its datasource and company name uses the companyBindingSource for its datasource. A company can have a supplier and/or customer account so the supplierBindingSource is a child or a companyBindingSource. The supplier accounts correctly filter based on the selected company name however when another company name is selected in another row all the supplier accounts are filtered for that company. Saving still works properly, regardless of what the combo box show but currently it is very confusing for a user to select a supplier account when the labels don't show what is being saved. Is it possible to have only the selected row to filter based on the company name rather than every row? EDIT: Thanks to the answer from http://social.msdn.microsoft.com/Forums/windows/en-US/b23d9e8f-a00a-49ba-adf5-52d87c1b2890/parent-child-comboboxes-in-datagridview I have been able to make some progress. The supplier account gets filtered when the drop down box is selected and restored to the full list when selection is finished. However now I am trying to have the company selected (and not filtered) when a supplier account is selected. The issue I've run into now is that I can get the companyID (which is the valuemember for the company combobox) but I cannot select the appropriate company without just setting the value of the combobox to the companyID which displays the companyID instead of the company name. Is there a way to select the company using the companyID while preserving the displaymember/valuemember dynamic? EDIT 2: The wall of text may be off putting. Some code to help elucidate my issue DataGridViewComboBoxCell dgcb2 = (DataGridViewComboBoxCell)sdgvSalesOrderLines[cmbSupplierName.Index, e.RowIndex]; var companyID = col.FirstOrDefault(c => c.AccountID == Convert.ToInt32(dgcb.Value)).CompanyID; dgcb2.Value = companyID.toString(); The second line gets the companyID and that works just fine, the final line sets the combobox to display the companyID whereas I would like it to set the valuemember value to companyID so that it would display the corresponding company name. I can set the second line to give me the company name instead but if the value of the combobox isn't the companyID then the supplier account cannot filter based on the company selected.

  • Angularjs togglecheck error(not working as intended) with prechecked data

    - by crozzfire
    I have this plunker where i have a button that opens a bootstrap modal dialog box. I the modal, when a course is selected(checked) from this list, it adds 3 to the $scope.planned and also increases the progress bar accordingly. Similarly it also reduces in the same way when a checkbox is unchecked. This is the function that does the above: $scope.toggleCheck = function (course) { //debugger var x = $scope.checkcoursefunction($scope.selectedCourses, course); if(x==true){ $scope.selectedCourses.splice($scope.selectedCourses.indexOf(course), 1); $scope.planned -= 3; } else{ if ($scope.selectedCourses.indexOf(course) === -1){ $scope.selectedCourses.push(course); $scope.planned += 3; } else { $scope.selectedCourses.splice($scope.selectedCourses.indexOf(course), 1); $scope.planned -= 3; } } $scope.getPercentage(); }; I have 2 services from where the controller fetches its data named Requirements and Planned Services. The table in the modal has a list of the requirements service data. I also have a function named checkplanneddetails() that checks if an item from this data is present in the requirements data. If present, they come in the table pre-checked. This is the function that checks: $scope.checkplanneddetails = function(course){ $scope.coursedetail = course; $scope.requirementcoursename = ($scope.coursedetail.course.subject).concat("-",$scope.coursedetail.course.course_no); for(var k = 0; k < $scope.planneddetails.length; k++){ if($scope.requirementcoursename==$scope.planneddetails[k].course_name){ $scope.selectedCourses.push(course); return true; } } return false; }; $scope.checkcoursefunction = function(arr,obj){ return (arr.indexOf(obj) != -1); } This works fine with bringing the data as checked. But the togglecheck() function does not work as they are supposed to with these checked details(they work in reverse). It always returns true(for var x in togglecheck) even after the splice function. Am i splicing the course correctly?

  • Adding a link to image breaks jquery slider, help please!

    - by lewisqic
    Hi All, I am working on a site for a friend and trying to add a link to each image in a slide show. The slide show uses jquery and a script called easySlider1.7.js. Everything works just fine if the images are left alone, but when I try and wrap the images with a link, the slides no longer progress as they should. Here is the live website that is displaying the problem... http://www.splits59.com/ Here is the html code for each of the slide images... <div class="covercontent2box"> <div class="covercontent2"> <div id="slideshow"> <a href="/ashton-jacket-p-107.html"><img src="img/homepagesummer2010_2.2-cut.jpg" class="active" /></a> <a href="/carly-coverup-p-106.html"><img src="img/homepagesummer2010_3.2-cut.jpg" /></a> <a href="/shop-online-bottoms-c-15_14.html"><img src="img/homepagesummer2010_1.2-cut.jpg" /></a> </div> </div> </div> And here is the jquery code on the page that controls the slider... <script type="text/javascript"> function slideSwitch() { var $active = $('#slideshow IMG.active'); if ( $active.length == 0 ) $active = $('#slideshow IMG:last'); // use this to pull the images in the order they appear in the markup var $next = $active.next().length ? $active.next() : $('#slideshow IMG:first'); $active.addClass('last-active'); $next.css({opacity: 0.0}) .addClass('active') .animate({opacity: 1.0}, 1000, function() { $active.removeClass('active last-active'); }); } $(function() { setInterval( "slideSwitch()", 4500 ); }); </script> Does anyone have any idea why adding a link tag to the images breaks the slider? Any help or direction provided would be appreciated. Thanks, Devin

  • How do I create a Spring 3 + Tiles 2 webapp using REST-ful URLs?

    - by Ichiro Furusato
    I'm having a heck of a time resolving URLs with Spring 3.0 MVC. I'm just building a HelloWorld to try out how to build a RESTful webapp in Spring, nothing theoretically complicated. All of the examples I've been able to find are based on configurations that pay attention to file extensions ("*.htm" or "*.do"), include an artificial directory name prefix ("/foo") or even prefix paths with a dot (ugly), all approaches that use some artificial regex pattern as a signal to the resolver. For a REST approach I want to avoid all that muck and use only the natural URL patterns of my application. I would assume (perhaps incorrectly) that in web.xml I'd set a url-pattern of "/*" and pass everything to the DispatcherServlet for resolution, then just rely on URL patterns in my controller. I can't reliably get my resolver(s) to catch the URL patterns, and in all my trials this results in a resource not found error, a stack overflow (loop), or some kind of opaque Spring 3 ServletException stack trace — one of my ongoing frustrations with Spring generally is that the error messages are not often very helpful. I want to work with a Tiles 2 resolver. I've located my *.jsp files in WEB-INF/views/ and have a single line index.jsp file at the application root redirecting to the index file set by my layout.xml (the Tiles 2 Configurer). I do all the normal Spring 3 high-level configuration: <mvc:annotation-driven /> <mvc:view-controller path="/" view-name="index"/> <context:component-scan base-package="com.acme.web.controller" /> ...followed by all sorts of combinations and configurations of UrlBasedViewResolver, InternalResourceViewResolver, UrlFilenameViewController, etc. with all manner of variantions in my Tiles 2 configuration file. Then in my controller I've trying to pick up my URL patterns. Problem is, I can't reliably even get the resolver(s) to catch the patterns to send to my controller. This has now stretched to multiple days with no real progress on something I thought would be very simple to implement. I'm perhaps trying to do too much at once, though I would think this should be a simple (almost a default) configuration. I'm just trying to create a simple HelloWorld-type application, I wouldn't expect this is rocket science. Rather than me post my own configurations (which have ranged all over the map), does anyone know of an online example that: shows a simple Spring 3 MVC + Tiles 2 web application that uses REST-ful URLs (i.e., avoiding forced URL patterns such as file extensions, added directory names or dots) and relies solely on Spring 3 code/annotations (i.e., nothing outside of Spring MVC itself) to accomplish this? Is there an easy way to do this? Thanks very much for any help.

  • Modular GWT design concerns

    - by GlGuru
    Hi, I have a couple of questions regarding a modular GWT based application framework. I have some ideas about them but being new to the field of web development I feel they are far from ideal. I'd appreciate a few comments and suggestions in this regard. Here are my questions: I am developing a framework which will allow third parties to embed GWT applications into our website and do some communication with them using simple iFrame postMessage. All these third party modules are going to use our SDK which is also GWT based. The problem arises that even though all the modules will be using the same codebase there is going to be a massive overheard in the amount of duplicate Javascript code (i.e. our common SDK code base which is quite large) being downloaded on the client's machine. This is highly redundant and problematic, not only due to the sheer size of duplicate code but, also due to the fact that subsequent updates of the SDK would require the modules to be recompiled which is going to create a DLL hell kind of scenario in the long run. What is the best way of doing this kind of thing? Is there a way where I can have some static GWT code (i.e. the SDK) and the dynamic GWT module refers to it (even if lies on a different domain) and it all work happily? The other part of the problem lies in providing robust scripting front end to the SDK. At first it appears to be trivial since Javascript itself is a scripting language. However, I do not know how to load and call a piece of pure Javascript code at runtime? I am willing to put restrictions on the target Javascript (i.e. having a function main and unique namespace or something). Furthermore the Javascript will come as a string from a database and not as a full URL. If its doable in Javascript how does one get this right in GWT i.e. forcing the compiler to emit a certain function in the generated Javascript? This I believe can be lesser of a problem by having a stub Javascript with all the right requirements which just loads up a GWT generated Javascript. Is any of this possible at all? I generally hate to be this verbose but I hope to find a quick solution to the problem as its holding up my progress. I'd highly appreciate any comments, suggestions and experiences.

  • Dealing with personal failure

    - by codeelegance
    A while ago I was given the task of updating and extending the functionality of a software project. I was given a year to make the needed changes working solo. A month into development I came to the conclusion that it would take longer to change the existing product than to rewrite it from the ground up. I'd never attempted a complete rewrite so I talked with my boss about it and he was thrilled with the idea. I'm a fan of agile development but had never had the opportunity to take advantage of all of the prescribed practices so when I set to work I tried to incorporate as many as I could. I didn't have direct access to the customer and my coworkers (non-programmers) knew the business domain but were already so busy they didn't really have time to participate in design meetings so I resigned to working in the dark and occasionally calling one of them over to my desk to get feedback on my progress. I used TDD and refactored mercilessly and even tried taking a domain driven design approach. Things went well for a while. As the deadline came closer and the complexity of the project grew my productivity start slipping. I found myself cutting corners and ignoring the practices I had established as the pressure increased to meet the deadline. I also started working late nights and weekends to keep up with the load. In the end it made little difference how hard I worked. The project missed its deadline and what was completed wasn't enough to give to the customer. I had failed. Not only had I not finished on time but the previous version had sat untouched for almost a year so it wouldn't be of any help. Luckily we had another product that offered some of the same functionality. My boss decided to cancel the project entirely and moved all our orphaned customers to the other product. I spent weeks (along with everyone else at the company) manning the phones providing technical support for those customers. After it was all over, my boss was gracious enough not to fire me for nearly ruining the company. I was moved to the other product and have been trying to redeem myself ever since. Where did I go wrong? Has anyone else had to deal with this kind of defeat? How did you recover?

  • How to "enable" HTML5 elements in IE that were inserted by AJAX call?

    - by Gidon
    IE does not work good with unknown elements (ie. HTML5 elements), one cannot style them , or access most of their props. Their are numerous work arounds for this for example: http://remysharp.com/2009/01/07/html5-enabling-script/ The problem is that this works great for static HTML that was available on page load, but when one creates HTML5 elements afterward (for example AJAX call containing them, or simply creating with JS), it will mark these newly added elements them as HTMLUnknownElement as supposed to HTMLGenericElement (in IE debugger). Does anybody know a work around for that, so that newly added elements will be recognized/enabled by IE? Here is a test page: <html><head><title>TIME TEST</title> <!--[if IE]> <script src="http://html5shiv.googlecode.com/svn/trunk/html5.js"></script> <![endif]--> <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js" type="text/javascript"></script> </head> <body> <time>some time</time> <hr> <script type="text/javascript"> $("time").text("WORKS GREAT"); $("body").append("<time>NEW ELEMENT</time>"); //simulates AJAX callback insertion $("time").text("UPDATE"); </script> </body> </html> In IE you will see the: UPDATE , and NEW ELEMENT. In any other modern browser you will see UPDATE, and UPDATE Solution Using the answer provided I came up with the following piece of javascript to HTML5 enable a whole bunch of elements returned by my ajax call: (function ($) { jQuery.fn.html5Enable = function () { if ($.browser.msie) { $("abbr, article, aside, audio, canvas, details, figcaption, figure, footer, header, hgroup, mark, menu, meter, nav, output, progress, section, summary, time, video", this).replaceWith(function () { if (this.tagName == undefined) return ""; var el = $(document.createElement(this.tagName)); for (var i = 0; i < this.attributes.length; i++) el.attr(this.attributes[i].nodeName, this.attributes[i].nodeValue); el.html(this.innerHtml); return el; }); } return this; }; })(jQuery); Now this can be called whenever you want to append something: var el = $(AJAX_RESULT_OR_HTML_STRING); el.html5Enable(); $("SOMECONTAINER").append(el); See http://code.google.com/p/html5shiv/issues/detail?id=4 for an explanation about what this plugin doesn't do.

  • Add Access-Control-Allow-Origin to header in PHP

    - by SANDeveloper
    I am trying to workaround CORS restriction on a WebGL application. I have a Web Service which resolves URL and returns images. Since this web service is not CORS enabled, I can't use the returned images as textures. I was planning to: Write a PHP script to handle image requests Image requests would be sent through the query string as a url parameter The PHP Script will: Call the web service with the query string url Fetch the image response (web service returns a content-type:image response) Add the CORS header (Add Access-Control-Allow-Origin) to the response Send the response to the browser I tried to implement this using a variety of techniques including CURL, HTTPResponse, plain var_dump etc. but got stuck at some point in each. So I have 2 questions: Is the approach good enough? Considering the approach is good enough: I made the most progress with CURL. I could get the image header and data with: $ch = curl_init(); $url = $_GET["url"]; curl_setopt($ch, CURLOPT_URL, $url); curl_setopt($ch, CURLOPT_HEADER, true); curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type:image/jpeg')); //Execute request $response = curl_exec($ch); //get the default response headers $headers = curl_getinfo($ch); //close connection curl_close($ch); But this doesn't actually change set the response content-type to image/jpeg. It dumps the header + response into a new response of content-type text/html and display the header and the image BLOB data in the browser. How do I get it to send the response in the format I want? Managed to get it working: $ch = curl_init(); $url = $_GET["url"]; curl_setopt($ch, CURLOPT_URL, $url); curl_setopt($ch, CURLOPT_HEADER, false); //Execute request $response = curl_exec($ch); //get the default response headers $headers = curl_getinfo($ch); curl_setopt($ch, CURLOPT_HTTPHEADER, $headers); header('Content-Type: image/jpeg'); header("Access-Control-Allow-Origin: *"); // header("Expires: Sat, 26 Jul 2017 05:00:00 GMT"); //close connection curl_close($ch); flush();

  • Exception showing a erroneous web page in a WPF frame
