  • Maven webapp with maven-eclipse-plugin doesn't generate <dependent-module>

    - by codevourer
    I use the eclipse:eclipse goal to generate an Eclipse Project environment. The deployment works fine. The goal creates the var classpath entries for all needed dependencies. With m2eclipse there was the Maven Container which defines an export folder which was WEB-INF/lib for me. But i don't want to rely on m2eclipse so i don't use it anymore. the class path entries which are generated by eclipse:eclipse goal don't have such a export folder. While booting the servlet container with WTP it publishes all resources and classes except the libraries to the context. Whats missing to publish the needed libs, or isn't that possible without m2eclipse integration? Enviroment Eclipse 3.5 JEE Galileo Apache Maven 2.2.1 (r801777; 2009-08-06 21:16:01+0200) Java version: 1.6.0_14 m2eclipse The maven-eclipse-plugin configuration <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-eclipse-plugin</artifactId> <version>2.8</version> <configuration> <projectNameTemplate>someproject-[artifactId]</projectNameTemplate> <useProjectReferences>false</useProjectReferences> <downloadSources>false</downloadSources> <downloadJavadocs>false</downloadJavadocs> <wtpmanifest>true</wtpmanifest> <wtpversion>2.0</wtpversion> <wtpapplicationxml>true</wtpapplicationxml> <wtpContextName>someproject-[artifactId]</wtpContextName> <additionalProjectFacets> <jst.web>2.3</jst.web> </additionalProjectFacets> </configuration> </plugin> The generated files After executing the eclipse:eclipse goal, the dependent-module is not listed in my generated .settings/org.eclipse.wst.common.component, so on server booting i miss the depdencies. This is what i get: <?xml version="1.0" encoding="UTF-8"?> <project-modules id="moduleCoreId" project-version="1.5.0"> <wb-module deploy-name="someproject-core"> <wb-resource deploy-path="/" source-path="src/main/java"/> <wb-resource deploy-path="/" source-path="src/main/webapp"/> <wb-resource deploy-path="/" source-path="src/main/resources"/> </wb-module> </project-modules> Update for upcoming readers The problem here was the deviant packaging-type, if u use maven-eclipse-plugin please validate the use of <packaging>war</packaging> or ear. The following problems are marked of the situations that i have two build-lifecycles in one maven pom.

  • HttpWebRequest: How to find a postal code at Canada Post through a WebRequest with x-www-form-enclos

    - by Will Marcouiller
    I'm currently writing some tests so that I may improve my skills with the Internet interaction through Windows Forms. One of those tests is to find a postal code which should be returned by Canada Post website. My default URL setting is set to: http://www.canadapost.ca/cpotools/apps/fpc/personal/findByCity?execution=e4s1 The required form fields are: streetNumber, streetName, city, province The contentType is "application/x-www-form-enclosed" EDIT: Please consider the value "application/x-www-form-encoded" instead of point 3 value as the contentType. (Thanks EricLaw-MSFT!) The result I get is not the result expected. I get the HTML source code of the page where I could manually enter the information to find the postal code, but not the HTML source code with the found postal code. Any idea of what I'm doing wrong? Shall I consider going the XML way? Is it first of all possible to search on Canada Post anonymously? Here's a code sample for better description: public static string FindPostalCode(ICanadadianAddress address) { var postData = string.Concat(string.Format("&streetNumber={0}", address.StreetNumber) , string.Format("&streetName={0}", address.StreetName) , string.Format("&city={0}", address.City) , string.Format("&province={0}", address.Province)); var encoding = new ASCIIEncoding(); byte[] postDataBytes = encoding.GetBytes(postData); request = (HttpWebRequest)WebRequest.Create(DefaultUrlSettings); request.ImpersonationLevel = System.Security.Principal.TokenImpersonationLevel.Anonymous; request.Container = new CookieContainer(); request.Timeout = 10000; request.ContentType = contentType; request.ContentLength = postDataBytes.LongLength; request.Method = @"post"; var senderStream = new StreamWriter(request.GetRequestStream()); senderStream.Write(postDataBytes, 0, postDataBytes.Length); senderStream.Close(); string htmlResponse = new StreamReader(request.GetResponse().GetResponseStream()).ReadToEnd(); return processedResult(htmlResponse); // Processing the HTML source code parsing, etc. } I seem stuck in a bottle neck in my point of view. I find no way out to the desired result. EDIT: There seems to have to parameters as for the ContentType of this site. Let me explain. There's one with the "meta"-variables which stipulates the following: meta http-equiv="Content-Type" content="application/xhtml+xml, text/xml, text/html; charset=utf-8" And another one later down the code that is read as: form id="fpcByAdvancedSearch:fpcSearch" name="fpcByAdvancedSearch:fpcSearch" method="post" action="/cpotools/apps/fpc/personal/findByCity?execution=e1s1" enctype="application/x-www-form-urlencoded" My question is the following: With which one do I have to stick? Let me guess, the first ContentType is to be considered as the second is only for another request to a function or so when the data is posted? EDIT: As per request, the closer to the solution I am is listed under this question: WebRequest: How to find a postal code using a WebRequest against this ContentType=”application/xhtml+xml, text/xml, text/html; charset=utf-8”? Thanks for any help! :-)

  • Running an allocation simulation repeatedly breaks after the first run.

    - by Az
    Background I have a bunch of students, their desired projects and the supervisors for the respective projects. I'm running a battery of simulations to see which projects the students end up with, which will allow me to get some useful statistics required for feedback. So, this is essentially a Monte-Carlo simulation where I'm randomising the list of students and then iterating through it, allocating projects until I hit the end of the list. Then the process is repeated again. Note that, within a single session, after each successful allocation of a project the following take place: + the project is set to allocated and cannot be given to another student + the supervisor has a fixed quota of students he can supervise. This is decremented by 1 + Once the quota hits 0, all the projects from that supervisor become blocked and this has the same effect as a project being allocated Code def resetData(): for student in students.itervalues(): student.allocated_project = None for supervisor in supervisors.itervalues(): supervisor.quota = 0 for project in projects.itervalues(): project.allocated = False project.blocked = False The role of resetData() is to "reset" certain bits of the data. For example, when a project is successfully allocated, project.allocated for that project is flipped to True. While that's useful for a single run, for the next run I need to be deallocated. Above I'm iterating through thee three dictionaries - one each for students, projects and supervisors - where the information is stored. The next bit is the "Monte-Carlo" simulation for the allocation algorithm. sesh_id = 1 for trial in range(50): for id in randomiseStudents(1): stud_id = id student = students[id] if not student.preferences: # Ignoring the students who've not entered any preferences for rank in ranks: temp_proj = random.choice(list(student.preferences[rank])) if not (temp_proj.allocated or temp_proj.blocked): alloc_proj = student.allocated_proj_ref = temp_proj.proj_id alloc_proj_rank = student.allocated_rank = rank successActions(temp_proj) temp_alloc = Allocated(sesh_id, stud_id, alloc_proj, alloc_proj_rank) print temp_alloc # Explained break sesh_id += 1 resetData() # Refer to def resetData() above All randomiseStudents(1) does is randomise the order of students. Allocated is a class defined as such: class Allocated(object): def __init__(self, sesh_id, stud_id, alloc_proj, alloc_proj_rank): self.sesh_id = sesh_id self.stud_id = stud_id self.alloc_proj = alloc_proj self.alloc_proj_rank = alloc_proj_rank def __repr__(self): return str(self) def __str__(self): return "%s - Student: %s (Project: %s - Rank: %s)" %(self.sesh_id, self.stud_id, self.alloc_proj, self.alloc_proj_rank) Output and problem Now if I run this I get an output such as this (truncated): 1 - Student: 7720 (Project: 1100241 - Rank: 1) 1 - Student: 7832 (Project: 1100339 - Rank: 1) 1 - Student: 7743 (Project: 1100359 - Rank: 1) 1 - Student: 7820 (Project: 1100261 - Rank: 2) 1 - Student: 7829 (Project: 1100270 - Rank: 1) . . . 1 - Student: 7822 (Project: 1100280 - Rank: 1) 1 - Student: 7792 (Project: 1100141 - Rank: 7) 2 - Student: 7739 (Project: 1100267 - Rank: 1) 3 - Student: 7806 (Project: 1100272 - Rank: 1) . . . 45 - Student: 7806 (Project: 1100272 - Rank: 1) 46 - Student: 7714 (Project: 1100317 - Rank: 1) 47 - Student: 7930 (Project: 1100343 - Rank: 1) 48 - Student: 7757 (Project: 1100358 - Rank: 1) 49 - Student: 7759 (Project: 1100269 - Rank: 1) 50 - Student: 7778 (Project: 1100301 - Rank: 1) Basically, it works perfectly for the first run, but on subsequent runs leading upto the nth run, in this case 50, only a single student-project allocation pair is returned. Thus, the main issue I'm having trouble with is figuring out what is causing this anomalous behaviour especially since the first run works smoothly. Thanks in advance, Az

  • Defines JEE 5 the handling of commit error using bean managed transactions?

    - by marabol
    I'm using glassfish 2.1 and 2.1.1. If I've a bean method annotated by @TransactionAttribute(value = TransactionAttributeType.REQUIRES_NEW). After doing some JPA stuff the commit fails in the afterCompletion-Phase of JTS. GlassFish logs this failure only. And the caller of this bean method has no chance to know something goes wrong. So I wonder, if there is any definition how a jee 5 server has to handle exceptions while commiting. I would expect any runtime exception. I'm using stateless beans. With SessionSynchronisation I could get the commit failue, if I use statefull beans. Is it possible to intercept, so I can throw an exception, that I've declared in my interface? This is the whole exception stacktrace:

  • Spring with Castor - Null Pointer Exception when initialising Application Context

    - by babyangel86
    Hi, I'm trying to register my castor mapping files with spring and I appear to be getting a null pointer exception.

  • Clickonce installation fails after addition of WCF service project

    - by Ant
    So I have a winform solution, deployed via clickonce. Eveything worked fine until i added a WCF project. (see error in parsing the manifest file at end of post) Now I notice that MSBuild compiles the service into a _PublishedWebsites dir. I don't know what the need for this is, but I am suspecting this is the cause of the problem. This wcf project references some other projects within the solution.

  • TripleDES in Perl/PHP/ColdFusion

    - by Seidr
    Recently a problem arose regarding hooking up an API with a payment processor who were requesting a string to be encrypted to be used as a token, using the TripleDES standard. Our Applications run using ColdFusion, which has an Encrypt tag - that supports TripleDES - however the result we were getting back was not what the payment processor expected. First of all, here is the resulting token the payment processor were expecting. AYOF+kRtg239Mnyc8QIarw== And below is the snippet of ColdFusion we were using, and the resulting string. <!--- Coldfusion Crypt (here be monsters) ---> <cfset theKey="123412341234123412341234"> <cfset theString = "username=test123"> <cfset strEncodedEnc = Encrypt(theString, theKey, "DESEDE", "Base64")> <!--- resulting string(strEncodedEnc): tc/Jb7E9w+HpU2Yvn5dA7ILGmyNTQM0h ---> As you can see, this was not returning the string we were hoping for. Seeking a solution, we ditched ColdFusion for this process and attempted to reproduce the token in PHP. Now I'm aware that various languages implement encryption in different ways - for example in the past managing encryption between a C# application and PHP back-end, I've had to play about with padding in order to get the two to talk, but my experience has been that PHP generally behaves when it comes to encryption standards. Anyway, on to the PHP source we tried, and the resulting string. /* PHP Circus (here be Elephants) */ $theKey="123412341234123412341234"; $theString="username=test123"; $strEncodedEnc=base64_encode(mcrypt_ecb (MCRYPT_3DES, $theKey, $theString, MCRYPT_ENCRYPT)); /* resulting string(strEncodedEnc): sfiSu4mVggia8Ysw98x0uw== */ As you can plainly see, we've got another string that differs from both the string expected by the payment processor AND the one produced by ColdFusion. Cue head-against-wall integration techniques. After many to-and-fro communications with the payment processor (lots and lots of reps stating 'we can't help with coding issues, you must be doing it incorrectly, read the manual') we were finally escalated to someone with more than a couple of brain-cells to rub together, who was able to step back and actually look at and diagnose the issue. He agreed, our CF and PHP attempts were not resulting in the correct string. After a quick search, he also agreed that it was not neccesarily our source, but rather how the two languages implemented their vision of the TripleDES standard. Coming into the office this morning, we were met by an email with a snippet of source code, in Perl. This is was the code they were directly using on their end to produce the expected token. #!/usr/bin/perl # Perl Crypt Calamity (here be...something) use strict; use CGI; use MIME::Base64; use Crypt::TripleDES; my $cgi = CGI->new(); my $param = $cgi->Vars(); $param->{key} = "123412341234123412341234"; $param->{string} = "username=test123"; my $des = Crypt::TripleDES->new(); my $enc = $des->encrypt3($param->{string}, $param->{key}); $enc = encode_base64($enc); $enc =~ s/\n//gs; # resulting string (enc): AYOF+kRtg239Mnyc8QIarw== So, there we have it. Three languages, three implementations of what they quote in the documentation as TripleDES Standard Encryption, and three totally different resulting strings. My question is, from your experience of these three languages and their implementations of the TripleDES algorithm, have you been able to get any two of them to give the same response, and if so what tweaks to the code did you have to make in order to come to the result? I understand this is a very drawn out question, but I wanted to give clear and precise setting for each stage of testing that we had to perform. I'll also be performing some more investigatory work on this subject later, and will post any findings that I come up with to this question, so that others may avoid this headache.

  • Two UIViews, one UIViewController (in one UINavigationController)

    - by jdandrea
    Given an iPhone app with a UITableViewController pushed onto a UINavigationController, I would like to add a right bar button item to toggle between the table view and an "alternate" view of the same data. Let's also say that this other view uses the same data but is not a UITableView. Now, I know variations on this question already exist on Stack Overflow. However, in this case, that alternate view would not be pushed onto the UINavigationController. It would be visually akin to flipping the current UIViewController's table view over and revealing the other view, then being able to flip back. In other words, it's intended to take up a single spot in the UINavigationController hierarchy. Moreover, whatever selection you ultimately make from within either view will push a common UIViewController onto the UINavigationController stack. Still more info: We don't want to use a separate UINavigationController just to handle this pair of views, and we don't want to split these apart via a UITabBarController either. Visually and contextually, the UX is meant to show two sides of the same coin. It's just that those two sides happen to involve their own View Controllers in normal practice. Now … it turns out I have already gone and quickly set this up to see how it might work! However, upon stepping back to examine it, I get the distinct impression that I went about it in a rather non-MVC way, which of course concerns me a bit. Here's what I did at a high level. Right now, I have a UIViewController (not a UITableViewController) that handles all commonalities between the two views, such as fetching the raw data. I also have two NIBs, one for each view, and two UIView objects to go along with them. (One of them is a UITableView, which is a kind of UIView.) I switch between the views using animation (easy enough). Also, in an effort to keep things encapsulated, the now-split-apart UITableView (not the UIViewController!) acts as its own delegate and data source, fetching data from the VC. The VC is set up as a weak, non-retained object in the table view. In parallel, the alternate view gets at the raw data from the VC in the exact same way. So, there are a few things that smell funny here. The weak linking from child to parent, while polite, seems like it might be wrong. Making a UITableView the table's data source and delegate also seems odd to me, thinking that a view controller is where you want to put that per Apple's MVC diagrams. As it stands now, it would appear as if the view knows about the model, which isn't good. Loading up both views in advance also seems odd, because lazy loading is no longer in effect. Losing the benefits of a UITableViewController (like auto-scrolling to cells with text fields) is also a bit frustrating, and I'd rather not reinvent the wheel to work around that as well. Given all of the above, and given we want that "flip effect" in the context of a single spot on a single UINavigationController, and given that both views are two sides of the same coin, is there a better, more obvious way to design this that I'm just happening to miss completely? Clues appreciated!

  • Why wont this JS code work if its all on the same line?

    - by culov
    I'm writing HTML code for a java servlet. i first write the code in html/js so i can debug what im working on, and then ill make it a java string and put it in my servlet. My problem is that the code is working fine when i view it in ff from a local html file, but when i view it on my java servlet, it doesnt work because the js isnt getting called. what I did was format the html that my servlet generated so that its not all on a single line and ran the code again. This time it worked. I copied this working code into a browser address bar so that it will all be on a single line, and copied that code back into the script in my html file. Now, when the previously working code is on a single line, it doesnt work. Here's the formatted JS: var sMax var holder; var preSet; var rated; var request; function rating(num){ sMax = 0; for(n=0; n<num.parentNode.childNodes.length; n++){ if(num.parentNode.childNodes[n].nodeName == "A"){ sMax++; } } if(!rated){ s = num.id.replace("_", ''); a = 0; for(i=1; i<=sMax; i++){ if(i<=s){ document.getElementById("_"+i).className = "on"; document.getElementById("rateStatus").innerHTML = num.title; holder = a+1; a++; }else{ document.getElementById("_"+i).className = ""; } } } } function off(me){ if(!rated){ if(!preSet){ for(i=1; i<=sMax; i++){ document.getElementById("_"+i).className = ""; document.getElementById("rateStatus").innerHTML = me.parentNode.title; } }else{ rating(preSet); document.getElementById("rateStatus").innerHTML = document.getElementById("ratingSaved").innerHTML; } } } function rateIt(me){ if(!rated){ document.getElementById("rateStatus").innerHTML = document.getElementById("ratingSaved").innerHTML + " "+me.title; preSet = me; rated=1; sendRate(me); rating(me); } } function sendRate(sel){ alert("Your rating was: "+sel.title); addRating("rating", "?truck=kogibbq?rating="+ sel.id); } function addRating(servletName, servletArguments){ var servlet = servletName; var arg = servletArguments var req = servlet + arg; alert(req); addrequest(req); request.onreadystatechange = function(){ alert("response received"); } } function addrequest(req) { try { request = new XMLHttpRequest(); }catch (e) { try { request = new ActiveXObject("Microsoft.XMLHTTP"); }catch (e) { alert("XMLHttpRequest error: " + e); } } request.open("GET", element, true); request.send(null); return request; } Thanks.

  • mediaelement.js control sizes are wrong when clip nested in a hidden element

    - by Martin Francis
    It's a nasty one this. In an audio control placed within a container element whose display property is initially set to none, the audio clip does NOT correctly size the progress bar when it is initialised. This is clear when the container's display property is changed from 'none' to '' (which is equivalent to 'static'). But who would ever do that? I make extensive use of 'tabbed' display arrangements on community sites like this one: http://www.churchesInBracebridge.ca Owing to the page arrangement, the audio controls which you see under 'sermons' (which at the time of writing still using Flash rather than John's excellent library here) are initially rendered in a div that is hidden. Simplified Test case Rather than have anyone have to wade through all of that, here's a much simplified test case: http://jsfiddle.net/sJL6T/36 Here's the full page source for those who'd prefer to work with it that way. <!DOCTYPE html> <html> <head> <meta http-equiv="content-type" content="text/html; charset=UTF-8"/> <title>MediaElementPlayer.js</title> <script type="text/javascript" src="//ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script> <script src="http://mediaelementjs.com/js/mejs-2.13.1/mediaelement-and-player.js"></script> <link rel="stylesheet" href="http://mediaelementjs.com/js/mejs-2.13.1/mediaelementplayer.css" /> <script type="text/javascript"> function toggle(id){ document.getElementById(id).style.display= (document.getElementById(id).style.display=='none' ? '' : 'none'); } </script> </head> <body> <h1>MediaElementPlayer.js</h1> <h2 onclick="return toggle('test1')">Initially Hidden (Click to toggle)</h2> <div id='test1' style='display:none'> <audio controls="controls"> <source src="http://mediaelementjs.com/media/AirReview-Landmarks-02-ChasingCorporate.mp3" type="audio/mp3" /> </audio> </div> <h2 onclick="return toggle('test2')">Initially Shown (Click to toggle)</h2> <div id='test2' style=''> <audio controls="controls"> <source src="http://mediaelementjs.com/media/AirReview-Landmarks-02-ChasingCorporate.mp3" type="audio/mp3" /> </audio> </div> <script> $('audio').mediaelementplayer(); </script> </body> </html> Possible Workarounds Now I know that Google maps has the same quirk and there are two possible ways I've used to deal with that: Use absolute positioning in a displayed div to place the element 10,000px to the left then bring it onto the stage when we want to see it Have the map pane displayed when loading then hide it as soon as it's loaded (ugly I know, but it usually works) However either approach would be a pain to do, as I have a lot of legacy code using the simpler div hiding method. I know that JQuery can get the dimensions of an element event if it is hidden - someone thoughtfully fiddled that and it does work: http://jsfiddle.net/sJL6T/9 Perhaps it may be possible to modify the actual library to find correct dimensions, even if the container itself is hidden? That would be wonderful, if it can be done! Initial experiments on mediaelement-and-player.js code I found that when I provided a fixed value in the setControlsSize function for railWidth, I got consistent results with both controls in the test case above (and obviously I'm working with my own copy of the library to do that, not the one stored at mediaelementjs.com): // outer area rail.width(railWidth); Change to this: // outer area railWidth=216; rail.width(railWidth); Many thanks in anticipation!

  • Link Error : xxx is already defined in *****.LIB :: What exactly is wrong?

    - by claws
    Problem: I'm trying to use a library named DCMTK which used some other external libraries ( zlib, libtiff, libpng, libxml2, libiconv ). I've downloaded these external libraries (*.LIB & *.h files ) from the same website. Now, when I compile the DCMTK library I'm getting link errors (793 errors) like this: Error 2 error LNK2005: __encode_pointer already defined in MSVCRTD.lib(MSVCR90D.dll) LIBCMTD.lib dcmmkdir Error 3 error LNK2005: __decode_pointer already defined in MSVCRTD.lib(MSVCR90D.dll) LIBCMTD.lib dcmmkdir Error 4 error LNK2005: __CrtSetCheckCount already defined in MSVCRTD.lib(MSVCR90D.dll) LIBCMTD.lib dcmmkdir Error 5 error LNK2005: __invoke_watson already defined in MSVCRTD.lib(MSVCR90D.dll) LIBCMTD.lib dcmmkdir Error 6 error LNK2005: __errno already defined in MSVCRTD.lib(MSVCR90D.dll) LIBCMTD.lib dcmmkdir Error 7 error LNK2005: __configthreadlocale already defined in MSVCRTD.lib(MSVCR90D.dll) LIBCMTD.lib dcmmkdir Error 8 error LNK2005: _exit already defined in MSVCRTD.lib(MSVCR90D.dll) LIBCMTD.lib dcmmkdir Documentation: This seems to be a popular error for this library so, they do have a FAQ entry addressing this issue which ( http://forum.dcmtk.org/viewtopic.php?t=35 ) says: The problem is that the linker tries to combine different, incompatible versions of the Visual C++ runtime library into a single binary. This happens when not all parts of your project and the libraries you link against are generated with the same code generation options in Visual C++. Do not use the /NODEFAULTLIB workaround, because strange software crashes may follow. Fix the problem! DCMTK is by default compiled with the "Multithreaded" or "Multithreaded Debug" code generation option (the latter for Debug mode). Either change the project settings of all of your code to use these code generation options, or change the code generation for all DCMTK modules and re-compile. MFC users beware: DCMTK should be compiled with "Multithreaded DLL" or "Multithreaded DLL Debug" settings if you want to link the libraries into an MFC application. Solution to same problem for others: http://stackoverflow.com/questions/2259697/vscopengl-huge-amount-of-linker-issues-with-release-build-only says: It seems that your release build is trying to link to something that was built debug. You probably have a broken dependency in your build, (or you missed rebuilding something to release by hand if your project is normally built in pieces). More technically, you seem to be linking projects built with different C Run Time library settings, one with "Multi-Threaded", another one with "Multi-Threaded Debug". Adjust the settings for all the projects to use the very same flavour of the library and the issue should go away Questions: Till now I used to think that Name mangling is the only problem that may cause linking failures if its not been standardized. Just now I knew there are other things also which can cause same effect. Whats up with the "Debug Mode" (Multi-Threaded Debug) and "Release Mode" (Multi-Threaded)? What exactly is happening under the hood? Why exactly this thing is causing linking error? I wonder if there is something called "Single-Threaded Debug" and "Single-Threaded" which again causes the same thing. Documentation talks something about "Code Generation Options". What Code Generation Options? WTH are they? Documentation specifically warns us not to use /NODEFAULTLIB workaround. (example /NODEFAULTLIB :msvcrt ). Why? How would I cause troubles? what exactly is it? Please explain the last point in the documentation for MFC users. Because I'm going to use MFC later in this project. Explain Why should we do it? What troubles would it cause if I don't. Anything more you'd like to mention? I mean regarding similar errors. I'm very interested in Linker & its problems. So, if there are any similar things you can mentions them or some keywords atleast.

  • I'm looking for an online ASP.NET tutor.

    - by pkiyan
    $15/hr. I know it's not much but... Hi. I'm looking for an ASP.NET tutor. I want to use a remote desktop application so we can see each others screens and use Skype or phone to communicate with. You won't need to come up with any lessons or anything like that. I was thinking we could spend an hour or two each time we logged in to build a decent sized website from scratch. That's basically it. I'm a beginner with about 2 months experience with ASP.NET so we won't have to start from the very beginning, but pretty close. I wanted this site to have a little complexity to it and not just a website for beginners, but something I could study for a while. I'll pay you through PayPal or some other method if you prefer. By the way, it doesn't have to be a website that we work on together. I'll listen to other suggestions too. Maybe we could use an open source site/app to walk-through and study and modify. I've looked at 'My Web Pages Starter Kit 1.30', 'SubText 2.1.2', 'nopCommerce 1.5', and some others. They were all beyond me, and I couldn't make sense of any of the source code. But if you use and are really familiar with an open source app/site that I can download, we could study that. Here are some technical specs about the site I'd like to build/study: ASP.NET 2.0+ (preferably 3.5+, but I don't really care) C# / VB.NET ( don't really care, I suck at both. This is more about ASP.NET and helping me understand the structure of an ASP.NET website and the .NET framework in general. ) SQL Server ( I have SQL Server 2008 express and would someday like to learn how to use this thing. ) JavaScript / AJAX ( at least some use of this ) XML ( basically, I'd like to spend some time in the web.config file, and have some sense of what's going on in there. ) ASP.NET Folders ( I'd like to work with all of the ASP.NET folders if possible: App_Code, App_GlobalResources, etc.. and understand what does/doesn't go in them. Hopefully we can build more than one theme too. ) Assemblies ( how do you create a .dll and use it across different websites? maybe you could suggest a third party .dll that we could use ) Web Service ( I read about this once but didn't really get it ) I can't think of anything else but the above will definitely keep me busy. Hopefully we could make use of a lot of the server controls too (the nav controls gave me a headache when I tried customizing them). Is someone willing to help? I'll pay through PayPal 15 bucks an hour. I live in the Dallas, Texas (US) area so we'd have to synchronize time zones and agree on a day(s)/time of the week. I prefer working at night and on the weekends because I work during the week but whatever your schedule allows too. If you'd like to help me, can you post: years of experience with ASP.NET, your Time zone and time you're available and any ideas you might have about how you'd like to tutor? THANK YOU.

  • Getting the DirectShow VideoRender filter to respond to MediaType changes on its Input Pin?

    - by Jonathan Websdale
    Below is the code extract from my decoder transform filter which takes in data from my source filter which is taking RTP network data from an IP camera. The source filter, decode filter can dynamically respond to changes in the camera image dimensions since I need to handle resolution changes in the decode library. I've used the 'ReceiveConnection' method as described in the DirectShow help, passing the new MediaType data in the next sample. However, I can't get the Video Mixing Renderer to accept the resolution changes dynamically even though the renderer will render the different resolution if the graph is stopped and restarted. Can anyone point out what I need to do to get the renderer to handle dynamic resolution changes? HRESULT CDecoder::Receive(IMediaSample* pIn) { //Input data does not necessarily correspond one-to-one //with output frames, so we must override Receive instead //of Transform. HRESULT hr = S_OK; //Deliver input to library long cBytes = pIn->GetActualDataLength(); BYTE* pSrc; pIn->GetPointer(&pSrc); try { hr = m_codec.Decode(pSrc, cBytes, (hr == S_OK)?&tStart : NULL); } catch (...) { hr = E_UNEXPECTED; } if (FAILED(hr)) { if (theLog.enabled()){theLog.strm() << "Decoder Error " << hex << hr << dec << " - resetting input"; theLog.write();} //Force reset of decoder m_bReset = true; m_codec.ResetInput(); //We have handled the error -- don't pass upstream or the source may stop. return S_OK; } //Extract and deliver any decoded frames hr = DeliverDecodedFrames(); return hr; } HRESULT CDecoder::DeliverDecodedFrames() { HRESULT hr = S_OK; for (;;) { DecodedFrame frame; bool bFrame = m_codec.GetDecodedFrame(frame); if (!bFrame) { break; } CMediaType mtIn; CMediaType mtOut; GetMediaType( PINDIR_INPUT, &mtIn); GetMediaType( PINDIR_OUTPUT, &mtOut); //Get the output pin's current image resolution VIDEOINFOHEADER* pvi = (VIDEOINFOHEADER*)mtOut.Format(); if( pvi->bmiHeader.biWidth != m_cxInput || pvi->bmiHeader.biHeight != m_cyInput) { HRESULT hr = GetPin(PINDIR_OUTPUT)->GetConnected()->ReceiveConnection(GetPin(PINDIR_OUTPUT), &mtIn); if(SUCCEEDED(hr)) { SetMediaType(PINDIR_OUTPUT, &mtIn); } } IMediaSamplePtr pOut; hr = m_pOutput->GetDeliveryBuffer(&pOut, 0, 0, NULL); if (FAILED(hr)) { break; } AM_MEDIA_TYPE* pmt; if (pOut->GetMediaType(&pmt) == S_OK) { CMediaType mt(*pmt); DeleteMediaType(pmt); SetMediaType(PINDIR_OUTPUT, &mt); pOut->SetMediaType(&mt); } // crop, tramslate and deliver BYTE* pDest; pOut->GetPointer(&pDest); m_pConverter->Convert(frame.Width(), frame.Height(), frame.GetY(), frame.GetU(), frame.GetV(), pDest); pOut->SetActualDataLength(m_pOutput->CurrentMediaType().GetSampleSize()); pOut->SetSyncPoint(true); if (frame.HasTimestamp()) { REFERENCE_TIME tStart = frame.Timestamp(); REFERENCE_TIME tStop = tStart+1; pOut->SetTime(&tStart, &tStop); } m_pOutput->Deliver(pOut); } return hr; }

  • [C#][XNA] Draw() 20,000 32 by 32 Textures or 1 Large Texture 20,000 Times

    - by Rudi
    The title may be confusing - sorry about that, it's a poor summary. Here's my dilemma. I'm programming in C# using the .NET Framework 4, and aiming to make a tile-based game with XNA. I have one large texture (256 pixels by 4096 pixels). Remember this is a tile-based game, so this texture is so massive only because it contains many tiles, which are each 32 pixels by 32 pixels. I think the experts will definitely know what a tile-based game is like. The orientation is orthogonal (like a chess board), not isometric. In the Game.Draw() method, I have two choices, one of which will be incredibly more efficient than the other. Choice/Method #1: Semi-Pseudocode: public void Draw() { // map tiles are drawn left-to-right, top-to-bottom for (int x = 0; x < mapWidth; x++) { for (int y = 0; y < mapHeight; y++) { SpriteBatch.Draw( MyLargeTexture, // One large 256 x 4096 texture new Rectangle(x, y, 32, 32), // Destination rectangle - ignore this, its ok new Rectangle(x, y, 32, 32), // Notice the source rectangle 'cuts out' 32 by 32 squares from the texture corresponding to the loop Color.White); // No tint - ignore this, its ok } } } Caption: So, effectively, the first method is referencing one large texture many many times, each time using a small rectangle of this large texture to draw the appropriate tile image. Choice/Method #2: Semi-Pseudocode: public void Draw() { // map tiles are drawn left-to-right, top-to-bottom for (int x = 0; x < mapWidth; x++) { for (int y = 0; y < mapHeight; y++) { Texture2D tileTexture = map.GetTileTexture(x, y); // Getting a small 32 by 32 texture (different each iteration of the loop) SpriteBatch.Draw( tileTexture, new Rectangle(x, y, 32, 32), // Destination rectangle - ignore this, its ok new Rectangle(0, 0, tileTexture.Width, tileTexture.Height), // Notice the source rectangle uses the entire texture, because the entire texture IS 32 by 32 Color.White); // No tint - ignore this, its ok } } } Caption: So, effectively, the second method is drawing many small textures many times. The Question: Which method and why? Personally, I would think it would be incredibly more efficient to use the first method. If you think about what that means for the tile array in a map (think of a large map with 2000 by 2000 tiles, let's say), each Tile object would only have to contain 2 integers, for the X and Y positions of the source rectangle in the one large texture - 8 bytes. If you use method #2, however, each Tile object in the tile array of the map would have to store a 32by32 Texture - an image - which has to allocate memory for the R G B A pixels 32 by 32 times - is that 4096 bytes per tile then? So, which method and why? First priority is speed, then memory-load, then efficiency or whatever you experts believe.

But when I pass argument to it ( That is in the previous code ) , then it prints a space for any character. What should I do?

  • Create a named cell dynamically

    - by CaptMorgan
    I have a workbook with 3 worksheets. 1 worksheet will have input values (not created at the moment and not needed for this question), 1 worksheet with several "template" or "source" tables, and the last worksheet has 4 formatted "target" tables (empty or not doesn't matter). Each template table has 3 columns, 1 column identifying what the values are for in the second 2 columns. The value columns have formulas in them and each cell is Named. The formulas use the cell Names rather than cell address (e.g. MyData1 instead of C2). I am trying to copy the templates into the target tables while also either copying the cell Names from the source into the targets or create the Names in the target tables based on the source cell Names. My code below I am creating the target names by using a "base" in the Name that will be changed depending on which target table it gets copied to. my sample tables have "Num0_" for a base in all the cell names (e.g. Num0_MyData1, Num0_SomeOtherData2, etc). Once the copy has completed the code will then name the cells by looking at the target Names (and address), replacing the base of the name with a new base, just adding a number of which target table it goes to, and replacing the sheet name in the address. Here's where I need help. The way I am changing that address will only work if my template and target are using the same cell addresses of their perspective sheets. Which they are not. (e.g. Template1 table has value cells, each named, of B2 thru C10, and my target table for the copy may be F52 thur G60). Bottom line I need to figure out how to copy those names over with the templates or name the cells dynamically by doing something like a replace where I am incrementing the address value based on my target table #...remember I have 4 target tables which are static, I will only copy to those areas. I am a newbie to vba so any suggestions or help is appreciated. NOTE: The copying of the table works as I want. It even names the cells (if the Template and Target Table have the same local worksheet cell address (e.g. C2) 'Declare Module level variables 'Variables for target tables are defined in sub's for each target table. Dim cellName As Name Dim newName As String Dim newAddress As String Dim newSheetVar Dim oldSheetVar Dim oldNameVar Dim srcTable1 Sub copyTables() newSheetVar = "TestSheet" oldSheetVar = "Templates" oldNameVar = "Num0_" srcTable1 = "TestTableTemplate" 'Call sub functions to copy tables, name cells and update functions. copySrc1Table copySrc2Table End Sub '****there is another sub identical to this one below for copySrc2Table. Sub copySrc1Table() newNameVar = "Num1_" trgTable1 = "SourceEnvTable1" Sheets(oldSheetVar).Select Range(srcTable1).Select Selection.Copy For Each cellName In ActiveWorkbook.Names 'Find all names with common value If cellName.Name Like oldNameVar & "*" Then 'Replace the common value with the update value you need newName = Replace(cellName.Name, oldNameVar, newNameVar) newAddress = Replace(cellName.RefersTo, oldSheetVar, newSheetVar) 'Edit the name of the name. This will change any formulas using this name as well ActiveWorkbook.Names.Add Name:=newName, RefersTo:=newAddress End If Next cellName Sheets(newSheetVar).Select Range(trgTable1).Select Selection.PasteSpecial Paste:=xlPasteAll, Operation:=xlNone, SkipBlanks:= _ False, Transpose:=False End Sub PING

  • Serious problem with WCF, GridViews, Callbacks and ExecuteReaders exceptions.

    - by barjed
    Hi, I have this problem that is driving me insane. I have a project to deliver before Thursday. Basically an app consiting of three components that communicate with each other in WCF. I have one console app and one Windows Forms app. The console app is a server that's connected to the database. You can add records to it via the Windows Forms client that connectes with the server through the WCF. The code for the client: namespace BankAdministratorClient { [CallbackBehavior(ConcurrencyMode = ConcurrencyMode.Single, UseSynchronizationContext = false)] public partial class Form1 : Form, BankServverReference.BankServerCallback { private BankServverReference.BankServerClient server = null; private SynchronizationContext interfaceContext = null; public Form1() { InitializeComponent(); interfaceContext = SynchronizationContext.Current; server = new BankServverReference.BankServerClient(new InstanceContext(this), "TcpBinding"); server.Open(); server.Subscribe(); refreshGridView(""); } public void refreshClients(string s) { SendOrPostCallback callback = delegate(object state) { refreshGridView(s); }; interfaceContext.Post(callback, s); } public void refreshGridView(string s) { try { userGrid.DataSource = server.refreshDatabaseConnection().Tables[0]; } catch (Exception ex) { MessageBox.Show(ex.ToString()); } } private void buttonAdd_Click(object sender, EventArgs e) { server.addNewAccount(Int32.Parse(inputPIN.Text), Int32.Parse(inputBalance.Text)); } private void Form1_FormClosing(object sender, FormClosingEventArgs e) { try { server.Unsubscribe(); server.Close(); }catch{} } } } The code for the server: namespace SSRfinal_tcp { class Program { static void Main(string[] args) { Console.WriteLine(MessageHandler.dataStamp("The server is starting up")); using (ServiceHost server = new ServiceHost(typeof(BankServer))) { server.Open(); Console.WriteLine(MessageHandler.dataStamp("The server is running")); Console.ReadKey(); } } } [ServiceBehavior(ConcurrencyMode = ConcurrencyMode.Single, InstanceContextMode = InstanceContextMode.PerCall, IncludeExceptionDetailInFaults = true)] public class BankServer : IBankServerService { private static DatabaseLINQConnectionDataContext database = new DatabaseLINQConnectionDataContext(); private static List<IBankServerServiceCallback> subscribers = new List<IBankServerServiceCallback>(); public void Subscribe() { try { IBankServerServiceCallback callback = OperationContext.Current.GetCallbackChannel<IBankServerServiceCallback>(); if (!subscribers.Contains(callback)) subscribers.Add(callback); Console.WriteLine(MessageHandler.dataStamp("A new Bank Administrator has connected")); } catch { Console.WriteLine(MessageHandler.dataStamp("A Bank Administrator has failed to connect")); } } public void Unsubscribe() { try { IBankServerServiceCallback callback = OperationContext.Current.GetCallbackChannel<IBankServerServiceCallback>(); if (subscribers.Contains(callback)) subscribers.Remove(callback); Console.WriteLine(MessageHandler.dataStamp("A Bank Administrator has been signed out from the connection list")); } catch { Console.WriteLine(MessageHandler.dataStamp("A Bank Administrator has failed to sign out from the connection list")); } } public DataSet refreshDatabaseConnection() { var q = from a in database.GetTable<Account>() select a; DataTable dt = q.toTable(rec => new object[] { q }); DataSet data = new DataSet(); data.Tables.Add(dt); Console.WriteLine(MessageHandler.dataStamp("A Bank Administrator has requested a database data listing refresh")); return data; } public void addNewAccount(int pin, int balance) { Account acc = new Account() { PIN = pin, Balance = balance, IsApproved = false }; database.Accounts.InsertOnSubmit(acc); database.SubmitChanges(); database.addNewAccount(pin, balance, false); subscribers.ForEach(delegate(IBankServerServiceCallback callback) { callback.refreshClients("New operation is pending approval."); }); } } } This is really simple and it works for a single window. However, when you open multiple instances of the client window and try to add a new record, the windows that is performing the insert operation crashes with the ExecuteReader error and the " requires an open and available connection. the connection's current state is connecting" bla bla stuff. I have no idea what's going on. Please advise.

  • mapping rect in small image to larger image (in order to do a copyPixels operation)

    - by skinnyTOD
    Hi all - this is (I think) a relatively simple math question but I've spent a day banging my head against it and have only the dents and no solution... I'm coding in actionscript 3 - the functionality is: large image loaded at runtime. The bitmapData is stored and a smaller version is created to display on the available screen area (I may end up just scaling the large image since it is in memory anyway). The user can create a rectangle hotspot on the smaller image (the functionality will be more complex: multiple rects with transparency: example a donut shape with hole, etc) 3 When the user clicks on the hotspot, the rect of the hotspot is mapped to the larger image and a new bitmap "callout" is created, using the larger bitmap data. The reason for this is so the "callout" will be better quality than just scaling up the area of the hotspot. The image below shows where I am at so far- the blue rect is the clicked hotspot. In the upper left is the "callout" - copied from the larger image. I have the aspect ratio right but I am not mapping to the larger image correctly. Ugly code below... Sorry this post is so long - I just figured I ought to provide as much info as possible.

  • Keeping socket open to send files on timer calls?

    - by user3704768
    I'm writing a program that requires an image to be fetched from a remote server every 10 milliseconds or so, as that's how often the image is updated. My current method calls a timer to grab the image, but it encounters Socket Closed errors all the time, and sometimes does not work at all. How can I fix my methods to keep the socket open the whole time, so no reconnecting is needed? Here is the full class: import java.awt.event.ActionEvent; import java.awt.event.ActionListener; import java.io.File; import java.io.FileInputStream; import java.io.FileNotFoundException; import java.io.FileOutputStream; import java.io.IOException; import java.net.InetAddress; import java.net.InetSocketAddress; import java.net.ServerSocket; import java.net.Socket; import java.net.UnknownHostException; import javax.swing.Timer; public class Connection { public static void createServer() throws IOException { Capture.getScreen(); ServerSocket socket = null; try { socket = new ServerSocket(12345, 0, InetAddress.getByName("127.0.0.1")); } catch (UnknownHostException e) { e.printStackTrace(); } catch (IOException e) { e.printStackTrace(); } System.out.println("Server started on " + socket.getInetAddress().getHostAddress() + ":" + socket.getLocalPort() + ",\nWaiting for client to connect."); final Socket clientConnection = socket.accept(); System.out.println("Client accepted from " + clientConnection.getInetAddress().getHostAddress() + ", sending file"); ActionListener taskPerformer = new ActionListener() { public void actionPerformed(ActionEvent evt) { System.out.println("Sending File"); try { pipeStreams(new FileInputStream(new File( "captures/sCap.png")), clientConnection.getOutputStream(), 1024); } catch (FileNotFoundException e) { e.printStackTrace(); } catch (IOException e) { e.printStackTrace(); } } }; System.out.println("closing out connection"); try { clientConnection.close(); } catch (IOException e) { e.printStackTrace(); } try { socket.close(); } catch (IOException e) { e.printStackTrace(); } Timer timer = new Timer(10, taskPerformer); timer.setRepeats(true); timer.start(); } public static void createClient() throws IOException { System.out.println("Connecting to server."); final Socket socket = new Socket(); try { socket.connect(new InetSocketAddress(InetAddress .getByName("127.0.0.1"), 12345)); } catch (UnknownHostException e) { e.printStackTrace(); } catch (IOException e) { } ActionListener taskPerformer = new ActionListener() { public void actionPerformed(ActionEvent evt) { System.out.println("Success, retreiving file."); try { pipeStreams(socket.getInputStream(), new FileOutputStream( new File("captures/rCap.png")), 1024); } catch (FileNotFoundException e) { e.printStackTrace(); } catch (IOException e) { } } }; System.out.println("Closing connection"); try { socket.close(); } catch (IOException e) { e.printStackTrace(); } Timer timer = new Timer(10, taskPerformer); timer.setRepeats(true); timer.start(); } public static void pipeStreams(java.io.InputStream source, java.io.OutputStream destination, int bufferSize) throws IOException { byte[] buffer = new byte[bufferSize]; int read = 0; while ((read = source.read(buffer)) != -1) { destination.write(buffer, 0, read); } destination.flush(); destination.close(); source.close(); } }
