• Assembly Load and loading the "sub-modules" dependencies - "cannot fild the file specified"

  - by Ted

  There are several questions out there that ask the same question. However the answers they received I cannot understand, so here goes: Similar questions: http://stackoverflow.com/questions/1874277/dynamically-load-assembly-and-manually-force-path-to-get-referenced-assemblies ; http://stackoverflow.com/questions/22012/loading-assemblies-and-its-dependencies-closed The question in short: I need to figure out how dependencies, ie References in my modules can be loaded dynamically. Right now I am getting "The system cannot find the file specified" on Assemblies referenced in my so called modules. I cannot really get how to use the AssemblyResolve event... The longer version I have one application, MODULECONTROLLER, that loads separate modules. These "separate modules" are located in well-known subdirectories, like appBinDir\Modules\Module1 appBinDir\Modules\Module2 Each directory contains all the DLLs that exists in the bin-directory of those projects after a build. So the MODULECONTROLLER loads all the DLLs contained in those folders using this code: byte[] bytes = File.ReadAllBytes(dllFileFullPath); Assembly assembly = null; assembly = Assembly.Load(bytes); I am, as you can see, loading the byte[]-array (so I dont lock the DLL-files). Now, in for example MODULE1, I have a static reference called MyGreatXmlProtocol. The MyGreatXmlProtocol.dll then also exists in the directory appBinDir\Modules\Module1 and is loaded using the above code When code in the MODULE1 tries to use this MyGreatXmlProtocol, I get: Could not load file or assembly 'MyGreatXmlProtocol, Version=1.0.3797.26527, Culture=neutral, PublicKeyToken=null' or one of its dependencies. The system cannot find the file specified. So, in a post (like this one) they say that To my understanding reflection will load the main assembly and then search the GAC for the referenced assemblies, if it cannot find it there, you can then incorparate an assemblyResolve event: First; is it really needed to use the AssemblyResolve-event to make this work? Shouldnt my different MODULEs themself load their DLLs, as they are statically referenced? Second; if AssemblyResolve is the way to go - how do I use it? I have attached a handler to the Event but I never get anything on MyGreatXmlProctol... === EDIT === CODE regarding the AssemblyResolve-event handler: public GUI() { InitializeComponent(); AppDomain.CurrentDomain.AssemblyResolve += new ResolveEventHandler(CurrentDomain_AssemblyResolve); ... } // Assembly CurrentDomain_AssemblyResolve(object sender, ResolveEventArgs args) { Console.WriteLine(args.Name); return null; } Hope I wasnt too fuzzy =) Thx

• How do you combine "Revision Control" with "WorkFlow" for R?

  - by Tal Galili

  Hello all, I remember coming across R users writing that they use "Revision control" (e.g: "Source control"), and I am curious to know: How do you combine "Revision control" with your statistical analysis WorkFlow? Two (very) interesting discussions talk about how to deal with the WorkFlow. But neither of them refer to the revision control element: http://stackoverflow.com/questions/1266279/how-to-organize-large-r-programs http://stackoverflow.com/questions/1429907/workflow-for-statistical-analysis-and-report-writing A Long Update To The Question: Following some of the people's answers, and Dirk's question in the comment, I would like to direct my question a bit more. After reading the Wiki article about "revision control" (which I was previously not familiar with), it was clear to me that when using revision control, what one does is to build a development structure of his code. This structure either leads to a "final product" or to several branches. When building something like, let's say, a website. There is usually one end product you work towards (the website), with some prototypes along the way. But when doing a statistical analysis, the work (to my view) is different. Sometimes you know where you want to get to. But more often, you explore. Explore cleaning the dataset. Explore different methods for statistical analysis, and ask various questions of your data (and I am writing this, knowing how Frank Harrell, and other experience statisticians feels about Data dredging). That is way the WorkFlow question with statistical programming is (in my view) a serious and deep question, raising many issues, The simpler ones are technical: Which revision control software do you use (and why) ? Which IDE do you use(and why) ? The more interesting question are about work process: How do you structure your files? What do you keep as a separate file and what as a revision? or asking in a different way - What should be a "branch" and what should be a "sub project" in your code? For example: When starting to explore your data, should a plot be creating and then erased because it didn't lead any where (but kept as a revision) or should there be a backup file of that path? How you solve this tension was my initial curiosity. The second question is "what might I be missing?". What rules (of thumb) should one follow so to avoid common pitfalls doing statistical programming with version control? In my intuition, I feel that statistical programming is inherently different then software development (I am writing this without being a real expert in statistical programming, and even less so in software development). That's way I am unsure which of the lessons I have read here about version control would be applicable. Thanks a lot, Tal

• GLKit Memory Leak copywithZone

  - by TommyT39

  Running the instruments utility against the game I'm writing shows a bunch of memory leaks related to copy with Zone when I cycle through an array and draw some simple cube objects. Im not sure the best way to track this down as I'm new to OpenGL programming. My program is using ARC and is set to build for IOS 5. I am initializing GLKit to use OPenGl 2.0 and using the BafeEffect so I don't have to write my own shaders etc.. This shouldn't be rocket science. Im guessing that I must be not releasing something within the draw function. Below is the code to my draw function. Could you guys take a look and see if anything stands out as the problem? One other thing to note is that I'm using 15 different textures, the cubes can be 1 of 15 different ones. I have a property set on the cube class for the texture and I set it as I create the cube in there array. But I do load all 15 when my programs view did load starts.They are small .jps files that are less than 75k each and each cube uses the same texture all the way around so shouldn't be too big of an issue. Here is the code to my draw function: - (void)draw { GLKMatrix4 xRotationMatrix = GLKMatrix4MakeXRotation(rotation.x); GLKMatrix4 yRotationMatrix = GLKMatrix4MakeYRotation(rotation.y); GLKMatrix4 zRotationMatrix = GLKMatrix4MakeZRotation(rotation.z); GLKMatrix4 scaleMatrix = GLKMatrix4MakeScale(scale.x, scale.y, scale.z); GLKMatrix4 translateMatrix = GLKMatrix4MakeTranslation(position.x, position.y, position.z); GLKMatrix4 modelMatrix = GLKMatrix4Multiply(translateMatrix,GLKMatrix4Multiply(scaleMatrix,GLKMatrix4Multiply(zRotationMatrix, GLKMatrix4Multiply(yRotationMatrix, xRotationMatrix)))); GLKMatrix4 viewMatrix = GLKMatrix4MakeLookAt(0, 0, 1, 0, 0, -5, 0, 1, 0); effect.transform.modelviewMatrix = GLKMatrix4Multiply(viewMatrix, modelMatrix); effect.transform.projectionMatrix = GLKMatrix4MakePerspective(0.125*M_TAU, 1.0, 2, 0); effect.texture2d0.name = wallTexture.name; [effect prepareToDraw]; glEnable(GL_DEPTH_TEST); glEnable(GL_CULL_FACE); glEnableVertexAttribArray(GLKVertexAttribPosition); glVertexAttribPointer(GLKVertexAttribPosition, 3, GL_FLOAT, GL_FALSE, 0, triangleVertices); glEnableVertexAttribArray(GLKVertexAttribTexCoord0); glVertexAttribPointer(GLKVertexAttribTexCoord0, 2, GL_FLOAT, GL_FALSE, 0, textureCoordinates); glDrawArrays(GL_TRIANGLES, 0, 18); glDisableVertexAttribArray(GLKVertexAttribPosition); glDisableVertexAttribArray(GLKVertexAttribTexCoord0); }

• libXcodeDebuggerSupport.dylib is missing in iOS 4.2.1 development SDK

  - by Kalle

  Note: creating a symbolic link to use the 4.2 lib seems to work fine -- maybe cd /Developer/Platforms/iPhoneOS.platform/DeviceSupport/4.2.1\ \(8C148\)/Symbols/ sudo ln -s ../../4.2 (8C134)/Symbols/Developer Request: See end of this question! After upgrading from 4.2.0 (beta, I believe) to 4.2.1, the libXcodeDebuggerSupport.dylib file is missing, which results in: warning: Unable to read symbols for /Developer/Platforms/iPhoneOS.platform/DeviceSupport/4.2.1 (8C148)/Symbols/Developer/usr/lib/libXcodeDebuggerSupport.dylib (file not found). which I guess isn't good. Looking at the directory in question I note: .../DeviceSupport/4.2 (8C134)/Symbols/Developer/usr/lib/libXcodeDebuggerSupport.dylib but .../DeviceSupport/4.2.1 (8C148)/Symbols/System/ .../DeviceSupport/4.2.1 (8C148)/Symbols/usr/ the above two dirs make up all the content in the 4.2.1 folder. No "Developer" folder. Checking the /usr/ dir there, I find no libXcodeDebuggerSupport.dylib file in the lib dir either, so ln -s'ing isn't an option. Worth mentioning: after the upgrade, I plugged the iPad in and had to click "Use for development" in Xcode organizer. Doing so, I got a message about symbols missing for that version, and Xcode proceeded to generate such, then failed. I restored the iPad and did "Use for development" again, and nothing about missing symbols appeared... Update: deletion of /Developer and reinstallation of Xcode from scratch does not fix this issue. Update 2: I just realized that after the reinstall of Xcode, .../DeviceSupport/4.2 (8C134)/Symbols is now a symbolic link, lrwxr-xr-x 1 root admin 36 Dec 3 17:17 Symbols -> ../../Developer/SDKs/iPhoneOS4.2.sdk And the directory in question has the appropriate files. Maybe this is simply a matter of linking the 4.2.1 dir in the same fashion? I'll try that and see if Xcode freaks out. If someone who has this file could provide a md5 sum that would be splendid. This is what it says for me: $ md5 /Developer/Platforms/iPhoneOS.platform/DeviceSupport/4.2\ \(8C134\)/Symbols/Developer/usr/lib/libXcodeDebuggerSupport.dylib MD5 (/Developer/Platforms/iPhoneOS.platform/DeviceSupport/4.2 (8C134)/Symbols/Developer/usr/lib/libXcodeDebuggerSupport.dylib) = 08f93a0a2e3b03feaae732691f112688 If the MD5 sum is identical to the output of $ md5 /Developer/Platforms/iPhoneOS.platform/DeviceSupport/4.2.1\ \(8C148\)/Symbols/Developer/usr/lib/libXcodeDebuggerSupport.dylib then we're all set.

• If we don't like it for the presentation layer, then why do we tolerate it for the behavior layer?

  - by greim

  Suppose CSS as we know it had never been invented, and the closest we could get was to do this: <script> // this is the page's stylesheet $(document).ready(function(){ $('.error').css({'color':'red'}); $('a[href]').css({'textDecoration':'none'}); ... }); </script> If this was how we were forced to write code, would we put up with it? Or would every developer on Earth scream at browser vendors until they standardized upon CSS, or at least some kind of declarative style language? Maybe CSS isn't perfect, but hopefully it's obvious how it's better than the find things, do stuff method shown above. So my question is this. We've seen and tasted of the glory of declarative binding with CSS, so why, when it comes to the behavioral/interactive layer, does the entire JavaScript community seem complacent about continuing to use the kludgy procedural method described above? Why for example is this considered by many to be the best possible way to do things: <script> $(document).ready(function(){ $('.widget').append("<a class='button' href='#'>...</div>"); $('a[href]').click(function(){...}); ... }); </script> Why isn't there a massive push to get XBL2.0 or .htc files or some kind of declarative behavior syntax implemented in a standard way across browsers? Is this recognized as a need by other web development professionals? Is there anything on the horizon for HTML5? (Caveats, disclaimers, etc: I realize that it's not a perfect world and that we're playing the hand we've been dealt. My point isn't to criticize the current way of doing things so much as to criticize the complacency that exists about the current way of doing things. Secondly, event delegation, especially at the root level, is a step closer to having a declarative behavior layer. It solves a subset of the problem, but it can't create UI elements, so the overall problem remains.)

• apply style to range of text with javascript in uiwebview

  - by drawnonward

  I am displaying some simple styled text as html in a UIWebView on iPhone. It is basically a series of paragraphs with the occasional strong or emphasized phrase. At runtime I need to apply styles to ranges of text. There are a few similar scenarios, one of which is highlighting search results. If the user has searched for "something" I would like to change the background color behind occurrences of the word, then later restore the original background. Is it possible to apply styles to ranges of text using javascript? A key part of this is also being able to unset the styles. There seem to be two likely paths to follow. One would be modifying some html in Objective-C and passing it through javascript as the new innerHTML of some container. The other would be to use javascript to directly manipulate DOM nodes. I could manipulate html, but that sounds tedious in Objective-C so I would rather manipulate the DOM if that is a reasonable approach. I am not that familiar with javascript and DOM so I do not know if it is a reasonable approach. I wrote some routines to translate between text ranges and node ranges with offsets. So if I start with text range 100-200 and that starts in one paragraph and ends in a third, I can get the text nodes and the offsets within the nodes that represent the given text range. I just need a way to split a text node at an offset in the text. Currently I just apply styles to the paragraphs containing the text range. A few notes: straight javascript please, no external frameworks like jquery. the changes never need to be written to disk. the changes should be undoable or at least removable. the styles to apply already exist in a css file. it needs to work in iPhone 3.0 and forward. all the source files are shipped with the app. please be verbose. Thanks for any suggestions.

• which way is correct to retrive data from oracle??

  - by rima

  before answer me plz thinking about the futures of these kind of program and answer me plz. I wanna get some data from oracle server like: 1-get all the function,package,procedure and etc for showing them or drop them & etc... 2-compile my *.sql files,get the result if they have problem & etc... becuz I was beginner in oracle first of all I for solve the second problem I try to connect to sqlPlus by RUN sqlplus and trace the output(I mean,I change the output stream of shell and trace what happend and handle the assigned message to customer. NOW THIS PART SUCCEED. just a little bit I have problem with get all result because the output is asynchronous.any way... [in this case I log in to oracle Server by send argument to the sqlplus by make a process in c#] after that I try to get all function,package or procedure name,but I have problem in speed!so I try to use oracle.DataAccess.dll to connect the database. now I m so confusing about: which way is correct way to build a program that work like Oracle Developer! I do not have any experience for like these program how work. If Your answer is I must use the second way follow this part plz: I search a little bit the Golden,PLedit (Benthic software),I have little bit problem how I must create the connection string?because I thinking about how I can find the host name or port number that oracle work on them?? am I need read the TNSNames.Ora file? IF your answer is I must use the first way follow this part plz: do u have any Idea for how I parse the output?because for example the result of a table is so confusing...[i can handle & program it but I really need someone experience,because the important things to me learn how such software work so nice and with quick response?] All of the has different style in output... If you are not sure Can u help me which book can help me in this way i become expert? becuz for example all the C# write just about how u can connect to DB and the DB books write how u can use this DB program,I looking for a book that give me some Idea how develop an interface for do transaction between these two.not simple send and receive data,for example how write a compiler for them. the language of book is not different for me i know C#,java,VB,sql,Oracle Thanks.

• Do You Really Know Your Programming Languages?

  - by Kristopher Johnson

  I am often amazed at how little some of my colleagues know or care about their craft. Something that constantly frustrates me is that people don't want to learn any more than they need to about the programming languages they use every day. Many programmers seem content to learn some pidgin sub-dialect, and stick with that. If they see a keyword or construct that they aren't familiar with, they'll complain that the code is "tricky." What would you think of a civil engineer who shied away from calculus because it had "all those tricky math symbols?" I'm not suggesting that we all need to become "language lawyers." But if you make your living as a programmer, and claim to be a competent user of language X, then I think at a minimum you should know the following: Do you know the keywords of the language and what they do? What are the valid syntactic forms? How are memory, files, and other operating system resources managed? Where is the official language specification and library reference for the language? The last one is the one that really gets me. Many programmers seem to have no idea that there is a "specification" or "standard" for any particular language. I still talk to people who think that Microsoft invented C++, and that if a program doesn't compile under VC6, it's not a valid C++ program. Programmers these days have it easy when it comes to obtaining specs. Newer languages like C#, Java, Python, Ruby, etc. all have their documentation available for free from the vendors' web sites. Older languages and platforms often have standards controlled by standards bodies that demand payment for specs, but even that shouldn't be a deterrent: the C++ standard is available from ISO for $30 (and why am I the only person I know who has a copy?). Programming is hard enough even when you do know the language. If you don't, I don't see how you have a chance. What do the rest of you think? Am I right, or should we all be content with the typical level of programming language expertise? Update: Several great comments here. Thanks. A couple of people hit on something that I didn't think about: What really irks me is not the lack of knowledge, but the lack of curiosity and willingness to learn. It seems some people don't have any time to hone their craft, but they have plenty of time to write lots of bad code. And I don't expect people to be able to recite a list of keywords or EBNF expressions, but I do expect that when they see some code, they should have some inkling of what it does. Few people have complete knowledge of every dark corner of their language or platform, but everyone should at least know enough that when they see something unfamiliar, they will know how to get whatever additional information they need to understand it.

  Hi, I have been struggling for a while now to get my filter graph to run .I am trying to crop a .wmv file into smaller duration .wmv files .It looks quite a simple task I dont know why its is getting so complicated.I follow this Source- SampleGrabber-WMA sf writer. Here is my code IBaseFilter* pASFWriter; ICaptureGraphBuilder2 * pBuilder=NULL; CoCreateInstance(CLSID_CaptureGraphBuilder2,NULL,CLSCTX_INPROC_SERVER,IID_ICaptureGraphBuilder2,(LPVOID*)&pBuilder); pBuilder-SetFiltergraph(pGraphBuilder); pBuilder-SetOutputFileName(&MEDIASUBTYPE_Asf,OUTFILE,&pASFWriter,NULL); IConfigAsfWriter *pConfig=NULL; HRESULT hr80 = pASFWriter-QueryInterface(IID_IConfigAsfWriter, (void**)&pConfig); if (SUCCEEDED(hr80)) { // Configure the ASF Writer filter. pConfig-Release(); } IBaseFilter *pSource=NULL; pGraphBuilder->AddSourceFilter(FILENAME,L"Source",&pSource); IBaseFilter *pGrabberF2=NULL; ISampleGrabber *pGrabber2=NULL; CoCreateInstance(CLSID_SampleGrabber,NULL,CLSCTX_INPROC_SERVER,IID_PPV_ARGS(&pGrabberF2)); pGraphBuilder->AddFilter(pGrabberF2,L"Sample Grabber2"); AM_MEDIA_TYPE mt1; ZeroMemory(&mt1,sizeof(mt1)); mt1.majortype=MEDIATYPE_Video; mt1.subtype=MEDIASUBTYPE_RGB24; pGrabberF2->QueryInterface(IID_ISampleGrabber,(void**)(&pGrabber2)); pGrabber2->SetBufferSamples(TRUE); pGrabber2->SetOneShot(FALSE); pGrabber->SetMediaType(&mt1); pSource->EnumPins(&pEnum2); pEnum2->Next(1,&pPin2,NULL); HRESULT hr108=ConnectFilters(pGraphBuilder,pPin2,pGrabberF2);//Source to Grabber pGrabberF2->EnumPins(&pEnum3); IEnumPins *pEnum4=NULL; pASFWriter->EnumPins(&pEnum4); IPin* pPin4=NULL; while (S_OK==pEnum3->Next(1,&pPin3,NULL)&& S_OK==pEnum4->Next(1,&pPin4,NULL)){ pGraphBuilder->Connect(pPin3,pPin4);//Grabber to FileWriter } pGraphBuilder->RenderFile(FILENAME,NULL);//FILENAME=INPUTFILENAME (.wmv format) pMediaPosition->put_CurrentPosition(start); pMediaPosition->put_StopTime(stop); HRESULT test1=pMediaControl->Run(); All of it runs fine(returns S_OK) .But test1 returns E_FAIL and no file is created.Can somebody help?

• Converting C source to C++

  - by Barry Kelly

  How would you go about converting a reasonably large (300K), fairly mature C codebase to C++? The kind of C I have in mind is split into files roughly corresponding to modules (i.e. less granular than a typical OO class-based decomposition), using internal linkage in lieu private functions and data, and external linkage for public functions and data. Global variables are used extensively for communication between the modules. There is a very extensive integration test suite available, but no unit (i.e. module) level tests. I have in mind a general strategy: Compile everything in C++'s C subset and get that working. Convert modules into huge classes, so that all the cross-references are scoped by a class name, but leaving all functions and data as static members, and get that working. Convert huge classes into instances with appropriate constructors and initialized cross-references; replace static member accesses with indirect accesses as appropriate; and get that working. Now, approach the project as an ill-factored OO application, and write unit tests where dependencies are tractable, and decompose into separate classes where they are not; the goal here would be to move from one working program to another at each transformation. Obviously, this would be quite a bit of work. Are there any case studies / war stories out there on this kind of translation? Alternative strategies? Other useful advice? Note 1: the program is a compiler, and probably millions of other programs rely on its behaviour not changing, so wholesale rewriting is pretty much not an option. Note 2: the source is nearly 20 years old, and has perhaps 30% code churn (lines modified + added / previous total lines) per year. It is heavily maintained and extended, in other words. Thus, one of the goals would be to increase mantainability. [For the sake of the question, assume that translation into C++ is mandatory, and that leaving it in C is not an option. The point of adding this condition is to weed out the "leave it in C" answers.]

• C#: My callback function gets called twice for every Sent Request

  - by Madi D.

  I've Got a program that uploads/downloads files into an online server,Has a callback to report progress and log it into a textfile, The program is built with the following structure: public void Upload(string source, string destination) { //Object containing Source and destination to pass to the threaded function KeyValuePair<string, string> file = new KeyValuePair<string, string>(source, destination); //Threading to make sure no blocking happens after calling upload Function Thread t = new Thread(new ParameterizedThreadStart(amazonHandler.TUpload)); t.Start(file); } private void TUpload(object fileInfo) { KeyValuePair<string, string> file = (KeyValuePair<string, string>)fileInfo; /* Some Magic goes here,Checking The file and Authorizing Upload */ var ftiObject = new FtiObject () { FileNameOnHDD = file.Key, DestinationPath = file.Value, //Has more data used for calculations. }; //Threading to make sure progress gets callback gets called. Thread t = new Thread(new ParameterizedThreadStart(amazonHandler.UploadOP)); t.Start(ftiObject); //Signal used to stop progress untill uploadCompleted is called. uploadChunkDoneSignal.WaitOne(); /* Some Extra Code */ } private void UploadOP(object ftiSentObject) { FtiObject ftiObject = (FtiObject)ftiSentObject; /* Some useless code to create the uri and prepare the ftiObject. */ // webClient.UploadFileAsync will open a thread that // will upload the file and report // progress/complete using registered callback functions. webClient.UploadFileAsync(uri, "PUT", ftiObject.FileNameOnHDD, ftiObject); } I got a callback that is registered to the Webclient's UploadProgressChanged event , however it is getting called twice per sent request. void UploadProgressCallback(object sender, UploadProgressChangedEventArgs e) { FtiObject ftiObject = (FtiObject )e.UserState; Logger.log(ftiObject.FileNameOnHDD, (double)e.BytesSent ,e.TotalBytesToSend); } Log Output: Filename: C:\Text1.txt Uploaded:1024 TotalFileSize: 665241 Filename: C:\Text1.txt Uploaded:1024 TotalFileSize: 665241 Filename: C:\Text1.txt Uploaded:2048 TotalFileSize: 665241 Filename: C:\Text1.txt Uploaded:2048 TotalFileSize: 665241 Filename: C:\Text1.txt Uploaded:3072 TotalFileSize: 665241 Filename: C:\Text1.txt Uploaded:3072 TotalFileSize: 665241 Etc... I am watching the Network Traffic using a watcher, and only 1 request is being sent. Some how i cant Figure out why the callback is being called twice, my doubt was that the callback is getting fired by each thread opened(the main Upload , and TUpload), however i dont know how to test if thats the cause. Note: The reason behind the many /**/ Comments is to indicate that the functions do more than just opening threads, and threading is being used to make sure no blocking occurs (there a couple of "Signal.WaitOne()" around the code for synchronization)

• MODX parse error function implode (is it me or modx?)

  - by Ian

  Hi, I cannot for the life of me figure this out, maybe someone can help. Using MODX a form takes user criteria to create a filter and return a list of documents. The form is one text field and a few checkboxes. If both text field and checkbox data is posted, the function works fine; if just the checkbox data is posted the function works fine; but if just the text field data is posted, modx gives me the following error: Error: implode() [function.implode]: Invalid arguments passed. I've tested this outside of modx with flat files and it all works fine leading me to assume a bug exists within modx. But I'm not convinced. Here's my code: <?php $order = array('price ASC'); //default sort order if(!empty($_POST['tour_finder_duration'])){ //duration submitted $days = htmlentities($_POST['tour_finder_duration']); //clean up post array_unshift($order,"duration DESC"); //add duration sort before default $filter[] = 'duration,'.$days.',4'; //add duration to filter[] (field,criterion,mode) $criteria[] = 'Number of days: <strong>'.$days.'</strong>'; //displayed on results page } if(!empty($_POST['tour_finder_dests'])){ //destination/s submitted $dests = $_POST['tour_finder_dests']; foreach($dests as $value){ //iterate through dests array $filter[] = 'searchDests,'.htmlentities($value).',7'; //add dests to filter[] $params['docid'] = $value; $params['field'] = 'pagetitle'; $pagetitle = $modx->runSnippet('GetField',$params); $dests_array[] = '<a href="[~'.$value.'~]" title="Read more about '.$pagetitle.'" class="tourdestlink">'.$pagetitle.'</a>'; } $dests_array = implode(', ',$dests_array); $criteria[] = 'Destinations: '.$dests_array; //displayed on results page } if(is_array($filter)){ $filter = implode('|',$filter);//pipe-separated string } if(is_array($order)){ $order = implode(',',$order);//comma-separated string } if(is_array($criteria)){ $criteria = implode('<br />',$criteria); } echo '<br />Order: '.$order.'<br /> Filter: '.$filter.'<br /> Criteria: '.$criteria; //next: extract docs using $filter and $order, display user's criteria using $criteria... ?> The echo statement is displayed above the MODX error message and the $filter array is correctly imploded. Any help will save my computer from flying out the window. Thanks

• Getting instance crashes on IntelliJ IDEA with scala plugin.

  - by egervari

  I am building a scala web project using scala test, lift, jpa, hibernate, mercurial plugin, etc. I am getting instant crashes, where the ide just bombs, the window shuts down, and it gives no error messages whatsoever when I am doing any amount of copy/pasting of code. This started happening once my project got to about 100 unit tests. This problem is incredibly annoying, because when the crash happens, 30-60 seconds of activity is not saved. Even IDEA will forget which files were last opened and will forget where the cursor was, which makes it really hard to continue where you left off after the crash. A lot can happen in 60 seconds! Now, I've given up, because it seems like all sorts of things cause the IntelliJ IDEA to crash over and over. For example, if I were to copy and paste this code, to write a similar test for another collection type, it would crash shortly after: it should "cascade save and delete status messages" in { val statusMessage = new StatusMessage("message") var user = userDao.find(1).get user.addToStatusMessages(statusMessage) userDao.save(user) statusMessage.isPersistent should be (true) userDao.delete(user) statusMessageDao.find(statusMessage.id) should equal (None) } There is nothing special about this piece of code. It's code that is working just fine. However, IDEA bombs shortly after I paste something like this. For example, I might change StatusMessage to the new class I want to test cascading on... and then have to import that class into the test... and BOOM... it crashed. On windows 7, the IDEA window literally just minimizes and crashes with no warning. The next time I startup IDEA, it has no memory of what happened. Now, I've had this problem before. I posted it way back on IDEA's YouTrack. I was told to invalidate my caches. That never fixed it then, and it's not fixing it now. Please help. This error is fairly random, but it's happening constantly now. I could program for hours and not see it before... and the fact that my work just gets destroyed and I can't remember what I did during the last minute causes me to swear at my monitor at a db level higher than my stereo can go.

  Hi there, I want use cookie in my web project. I must serialize my classes. Although my code can seralize an int or string value, it cant seralize my classes. This is my seralize and cookie code : public static bool f_SetCookie(string _sCookieName, object _oCookieValue, DateTime _dtimeExpirationDate) { bool retval = true; try { if (HttpContext.Current.Request[_sCookieName] != null) { HttpContext.Current.Request.Cookies.Remove(_sCookieName); } BinaryFormatter bf = new BinaryFormatter(); MemoryStream ms = new MemoryStream(); bf.Serialize(ms, _oCookieValue); byte[] bArr = ms.ToArray(); MemoryStream objStream = new MemoryStream(); DeflateStream objZS = new DeflateStream(objStream, CompressionMode.Compress); objZS.Write(bArr, 0, bArr.Length); objZS.Flush(); objZS.Close(); byte[] bytes = objStream.ToArray(); string sCookieVal = Convert.ToBase64String(bytes); HttpCookie cook = new HttpCookie(_sCookieName); cook.Value = sCookieVal; cook.Expires = _dtimeExpirationDate; HttpContext.Current.Response.Cookies.Add(cook); } catch { retval = false; } return retval; } And here is one of my classes: [Serializable] public class Tahlil { #region Props & Fields public string M_KlinikKodu{ get; set; } public DateTime M_AlinmaTarihi { get; set; } private List<Test> m_Tesler; public List<Test> M_Tesler { get { return m_Tesler; } set { m_Tesler = value; } } #endregion public Tahlil() {} Tahlil(DataRow _rwTahlil){} } I m calling my Set Cookie method: Tahlil t = new Tahlil(); t.M_AlinmaTarihi = DateTime.Now; t.M_KlinikKodu = "2"; t.M_Tesler = new List<Test>(); f_SetCookie("Tahlil", t, DateTime.Now.AddDays(1)); I cant see cookie in Cookie folder and Temporary Internet Files but if i will call method like that: f_SetCookie("TRY", 5, DateTime.Now.AddDays(1)); I can see cookie. What is the problem? I dont understand. Thank you for your helps.

• Why i get everytime the error-message that i've already sent the headers

• PHP Copy-Paste Detector

  - by user1615069

  My problem is that when I run phpcpd command I always get 0% doubled code result, no matter if it's my project, if it's any php module's files, or if it's a file I created to check if phpcpd works...For example when I check the file below it also displays 0%: phpcpd folder/file.php: <?php class Class_Two { public function aaa() { if(2 == 2) { echo 'ok'; } } public function aaa() { if(2 == 2) { echo 'ok'; echo 'ok'; echo 'ok'; echo 'ok'; echo 'ok'; echo 'ok'; } } public function aaa() { if(2 == 2) { echo 'ok'; } } public function aaa() { if(2 == 2) { echo 'ok'; echo 'ok'; echo 'ok'; echo 'ok'; echo 'ok'; echo 'ok'; } } public function aaa() { if(2 == 2) { echo 'ok'; } } public function aaa() { if(2 == 2) { echo 'ok'; echo 'ok'; echo 'ok'; echo 'ok'; echo 'ok'; echo 'ok'; } } public function aaa() { if(2 == 2) { echo 'ok'; } } public function aaa() { if(2 == 2) { echo 'ok'; echo 'ok'; echo 'ok'; echo 'ok'; echo 'ok'; echo 'ok'; } } public function aaa() { if(2 == 2) { echo 'ok'; } } public function aaa() { if(2 == 2) { echo 'ok'; echo 'ok'; echo 'ok'; echo 'ok'; echo 'ok'; echo 'ok'; } } public function aaa() { if(2 == 2) { echo 'ok'; } } public function aaa() { if(2 == 2) { echo 'ok'; echo 'ok'; echo 'ok'; echo 'ok'; echo 'ok'; echo 'ok'; } } } class Class_Two { public function aaa() { if(2 == 2) { echo 'ok'; } } public function aaa() { if(2 == 2) { echo 'ok'; } } } Any suggestions on why isn't it working properly? Or maybe it is supposed to do some other tasks?

• Intent filter for browsing XML (specifically rss) in android

  - by Leif Andersen

  I have an activity that I want to run every time the user goes to an xml (specifically rss) page in the browser (at least assuming the user get's it from the list of apps that can support it). I currently already have the current intent filter: <activity android:name=".activities.EpisodesListActivity" android:theme="@android:style/Theme.NoTitleBar"> <intent-filter> <category android:name="android.intent.category.BROWSABLE"></category> <category android:name="android.intent.category.DEFAULT"></category> <action android:name="android.intent.action.VIEW"></action> <data android:scheme="http"></data> </intent-filter> </activity> Now as you can guess, this is an evil intent, as it wants to open whenever a page is requested via http. However, when I ad the line: <data android:mimeType="application/rss+xml"></data> to make it: <activity android:name=".activities.EpisodesListActivity" android:theme="@android:style/Theme.NoTitleBar"> <intent-filter> <category android:name="android.intent.category.BROWSABLE"></category> <category android:name="android.intent.category.DEFAULT"></category> <action android:name="android.intent.action.VIEW"></action> <data android:scheme="http"></data> <data android:mimeType="application/rss+xml"></data> </intent-filter> </activity> The application no longer claims to be able to run rss files. Also, if I change the line to: <data android:mimeType="application/xml"></data> It also won't work (for generic xml file even). So what intent filter do I need to make in order to claim that the activity supports rss. (Also, bonus points if you can tell me how I know what URL it was the user opened. So far, I've always sent that information from one activity to the other using extras). Thank you for your help

• Why are these two sql statements deadlocking? (Deadlock graph + details included).

  - by Pure.Krome

  Hi folks, I've got the following deadlock graph that describes two sql statements that are deadlocking each other. I'm just not sure how to analyse this and then fix up my sql code to prevent this from happening. Main deadlock graph Click here for a bigger image. Left side, details Click here for a bigger image. Right side, details Click here for a bigger image. What is the code doing? I'm reading in a number of files (eg. lets say 3, for this example). Each file contains different data BUT the same type of data. I then insert data into LogEntries table and then (if required) I insert or delete something from the ConnectedClients table. Here's my sql code. using (TransactionScope transactionScope = new TransactionScope()) { _logEntryRepository.InsertOrUpdate(logEntry); // Now, if this log entry was a NewConnection or an LostConnection, then we need to make sure we update the ConnectedClients. if (logEntry.EventType == EventType.NewConnection) { _connectedClientRepository.Insert(new ConnectedClient { LogEntryId = logEntry.LogEntryId }); } // A (PB) BanKick does _NOT_ register a lost connection .. so we need to make sure we handle those scenario's as a LostConnection. if (logEntry.EventType == EventType.LostConnection || logEntry.EventType == EventType.BanKick) { _connectedClientRepository.Delete(logEntry.ClientName, logEntry.ClientIpAndPort); } _unitOfWork.Commit(); transactionScope.Complete(); } Now each file has it's own UnitOfWork instance (which means it has it's own database connection, transaction and repository context). So i'm assuming this means there's 3 different connections to the db all happening at the same time. Finally, this is using Entity Framework as the repository, but please don't let that stop you from having a think about this problem. Using a profiling tool, the Isolation Level is Serializable. I've also tried ReadCommited and ReadUncommited, but they both error :- ReadCommited: same as above. Deadlock. ReadUncommited: different error. EF exception that says it expected some result back, but got nothing. I'm guessing this is the LogEntryId Identity (scope_identity) value that is expected but not retrieve because of the dirty read. Please help! PS. It's Sql Server 2008, btw.

• How to split a string with negative numbers using ActionScript 3.0

  - by inzombiak

  I'm having trouble loading my level. I'm using Ogmo to create my level then I import it. I have no problem converting 0's and 1's into an Array, but I can't figure out how to do the same for -1's. It separates the "-" and the "1". Any help would be great. I've posted my code and the XML files below levelXML = new XML(e.target.data); playerX = int(levelXML.Entities.Player.@x); playerY = int(levelXML.Entities.Player.@y); levelGrid = levelXML.Grid; levelGrid = levelGrid.split("\n").join(""); levelTiles = levelXML.Tiles; levelTiles = levelTiles.split("\n").join(""); levelTiles = levelTiles.split(",").join(""); tileArray = levelTiles.split(""); gridArray = levelGrid.split(""); for(i = 0; i <= 34; i++) { levelArray[i] = new Array(); for(j = 0; j <= 34; j++) { if(tileArray[j*35 + i] == 0) { gridArray[j*35+i] = -1; } var currentSymbol = gridArray[j*35+i]; levelArray[i][j] = currentSymbol; if(gridArray[j*35 + i] == 1) { wall = new Wall; addChild(wall); wall.x = i*20 + 10; wall.y = j*20 + 10; } else if(gridArray[j*35 + i] == -1) { pellet = new Pellet; addChild(pellet); pellet.x = i*20 + 10; pellet.y = j*20 + 10; } } } I know the code is very dirty, but I needed a quick fix.

• Add jquery link to returned text...

  - by Jerry

  Hi all I am trying to add two jquery plugins files to my application. When a user triggers my ajax event, the server will return text with a form button. The plugins (a jquery calendar) will work when the user clicks the form button inside the returned text . I believe I have to add the link inside the return text instead of the main page to let the code work, but not sure how to do this. I am giving out my code and need you experts opinions. Thanks. My main page html //required jquery plugins ...didn't work if I add them in the main application. <script type="text/javascript" src="JS/date.js"></script> <script type="text/javascript" src="JS/datePicker.js"></script> <script type="text/javascript" src="JS/selectWeek.js"></script> <div id="gameInfo"> //return text will be displayed here. </div> My returned text ...part of it.... <form> <div id=returnDiv> // the form input will be added here when a user clicks #addMatch button... </div> <tr> <td><input type="button" id="addMatch" name="addMatch" value="Add Match"/> </td> </tr> </form> My jquery $("#addMatch").live('click', function(){ //the code below will create a calender when a user click the link...I am not sure //where I should add my two jquery plugins link... $("#returnDiv").html("<td><input type='text' size='6' class='date-pick dp-applied'"+ "name='date'><a style='color:white;' class='dp-choose-date' title='Choose Date'"+ "href='#'>Date</a></td>"; return false; }); I hope I explain my question well. +1 to any reply...:D
