  • Using ssh for remote command

    - by user1663479
    I need to use ssh to execute a remote command such as: ssh -l jsilva xman /vol/2011/linux_x64/exe/mx201111.exe When I execute ssh I receive error message: /cmg/2011.11/linux_x64/exe/mx201111.exe: error while loading shared libraries: libmkl_intel_lp64.so: cannot open shared object file: No such file or directory This application uses the variable LD_LIBRARY_PATH. I inserted this variable into /etc/profiles in localhost and remote host. The filesystem /cmg is mounted by autofs for both hosts (local and remote). Anybody have idea how to resolve this problem? Thanks!

  • ASP.NET MVC: Posting JSON to Controller

    - by JamesBrownIsDead
    I've got this in my controller: [HttpPost] public void UpdateLanguagePreference(string languageTag) { if (string.IsNullOrEmpty(languageTag)) { throw new ArgumentNullException("languageTag"); } ... } And have this jQuery code POSTing to the controller: jQuery.ajax({ type: 'POST', url: '/Config/UpdateLanguagePreference', contentType: 'application/json; charset=utf-8', data: '{ "languageTag": "' + selectedLanguage + '" }' }); When I try to the code, however, I get the error: Server Error in '/' Application. Value cannot be null. Parameter name: languageTag What's the problem? Isn't this how to POST JSON to an MVC Controller? I can examine the POST using Fiddler and see that the request is correct. For some reason, UpdateLanguagePreference() is getting a null or empty string.

  • Loading url with cyrillic symbols

    - by Ockonal
    Hi guys, I have to load some url with cyrillic symbols. My script should work with this: http://wincode.org/%D0%BF%D1%80%D0%BE%D0%B3%D1%80%D0%B0%D0%BC%D0%BC%D0%B8%D1%80%D0%BE%D0%B2%D0%B0%D0%BD%D0%B8%D0%B5/ If I'll use this in browser it would replaced into normal symbols, but urllib code fails with 404 error. How to decode correctly this url? When I'm using that url directly in code, like address = 'that address', it works perfect. But I used parsing page for getting this url. I have a list of urls which contents cyrillic. Maybe they have uncorrect encoding? Here is more code: requestData = urllib2.Request( %SOME_ADDRESS%, None, {"User-Agent": user_agent}) requestHandler = pageHandler.open(requestData) pageData = requestHandler.read().decode('utf-8') soupHandler = BeautifulSoup(pageData) topicLinks = [] for postBlock in soupHandler.findAll('a', href=re.compile('%SOME_REGEXP%')): topicLinks.append(postBlock['href']) postAddress = choice(topicLinks) postRequestData = urllib2.Request(postAddress, None, {"User-Agent": user_agent}) postHandler = pageHandler.open(postRequestData) postData = postHandler.read() File "/usr/lib/python2.6/urllib2.py", line 518, in http_error_default raise HTTPError(req.get_full_url(), code, msg, hdrs, fp) urllib2.HTTPError: HTTP Error 404: Not Found

  • T-SQL: How Do I Create A "Private" Function Inside A Stored Procedure

    - by RPM1984
    Okay so im writing a SQL Server 2008 Stored Procedure (maintenance script). In doing so, being a good boy i've done plenty of error handling, checking rowcounts, printing output messages, etc But in doing this, ive found myself writing over and over again something like this: SELECT @RowsAffected = @@ROWCOUNT IF @RowsAffected > 0 BEGIN PRINT CAST(@RowsAffected, NVARCHAR(2)) + 'rows updated.' END Or debug messages like this: PRINT 'User ' + CAST(@UserId AS NVARCHAR(5)) + ' modified successfully' Is there a way i can create a kind of 'subroutine' inside the stored procedure (like a private method) that can accept something as a parameter (doesnt have to though) and do some logic? I want to be able to do something like this: CheckRowCounts Or this: PrintUserUpatedMessage(@UserId) Which would then perform the above logic (check rowcount, print message, etc) And yes obviously i can create a UDF, but then i would need to create/drop it etc as this logic is only required for the life of the execution of this stored procedure. Getting sick and tired of writing the same code over and over again, and changing all the different areas ive used it when i get an error =) Can anyone help?

  • Recommendations for a C++ polymorphic, seekable, binary I/O interface

    - by Trevor Robinson
    I've been using std::istream and ostream as a polymorphic interface for random-access binary I/O in C++, but it seems suboptimal in numerous ways: 64-bit seeks are non-portable and error-prone due to streampos/streamoff limitations; currently using boost/iostreams/positioning.hpp as a workaround, but it requires vigilance Missing operations such as truncating or extending a file (ala POSIX ftruncate) Inconsistency between concrete implementations; e.g. stringstream has independent get/put positions whereas filestream does not Inconsistency between platform implementations; e.g. behavior of seeking pass the end of a file or usage of failbit/badbit on errors Don't need all the formatting facilities of stream or possibly even the buffering of streambuf streambuf error reporting (i.e. exceptions vs. returning an error indicator) is supposedly implementation-dependent in practice I like the simplified interface provided by the Boost.Iostreams Device concept, but it's provided as function templates rather than a polymorphic class. (There is a device class, but it's not polymorphic and is just an implementation helper class not necessarily used by the supplied device implementations.) I'm primarily using large disk files, but I really want polymorphism so I can easily substitute alternate implementations (e.g. use stringstream instead of fstream for unit tests) without all the complexity and compile-time coupling of deep template instantiation. Does anyone have any recommendations of a standard approach to this? It seems like a common situation, so I don't want to invent my own interfaces unnecessarily. As an example, something like java.nio.FileChannel seems ideal. My best solution so far is to put a thin polymorphic layer on top of Boost.Iostreams devices. For example: class my_istream { public: virtual std::streampos seek(stream_offset off, std::ios_base::seekdir way) = 0; virtual std::streamsize read(char* s, std::streamsize n) = 0; virtual void close() = 0; }; template <class T> class boost_istream : public my_istream { public: boost_istream(const T& device) : m_device(device) { } virtual std::streampos seek(stream_offset off, std::ios_base::seekdir way) { return boost::iostreams::seek(m_device, off, way); } virtual std::streamsize read(char* s, std::streamsize n) { return boost::iostreams::read(m_device, s, n); } virtual void close() { boost::iostreams::close(m_device); } private: T m_device; };

  • DataAnnotationsModelBinder with MVC2 RTM

    - by yang
    Trying to validate models with DataAnnotations but DefaulModelBinder overrides my Required property error messages and never uses my error messages for invalid data entry. Always show 'value' is invalid for 'property name'. In another question I saw that MVC 2 uses DefaultModelBinder but I couldn't find any class in MVC 2 binaries. I downloaded the source for MVC futures and changed some source to compile it for .Net 4.0 but although I had success to compile, it has compatability problems and doesn't work as expected. Any help is aprreciated.

  • java spring and ftl

    - by bobby
    I defined a modelview object named "buttonpressed" in spring controller file and I need to access that modelview object in ftl(freemarker) file which is being returned as a view from a controller like abcd.java The abcd.java controller code is as below if (questionAnswer.getAnswerId() == 1045) { modelAndView.addObject("buttonPressed","You have been added in mailing list"); modelAndView.setViewName("enterCode_nextSteps"); } else { modelAndView.addObject("buttonPressed","Not added in the mailing list"); modelAndView.setViewName("enterCode_nextSteps"); } the below ajax function is working fine currently but I am not sure how to access this object called "buttonpressed" in this ajax function. I have written like the way mentioned below but when i am clicking the submit link its not calling "partner.do" and also throwing error saying #buttonPressed is undefind (but in the script below its working fine and calling "partner.do" and even posting data) So is that problem coming from javsscript code i mean due to incorrect use of "buttonPressed" or might be problem from spring controller abcd.java file. <div class="partnerOptInBox"> <div id="optInContent"> <form name="partnerOptIn"> <h4>Want the Latest</h4> <p class="pad10Top">${partnerOpt.translation}</p> <div class="pad10Top"> <input type="radio" name="questionAnswer['${partnerOpt.questionId}']" value="${partnerOpt.getAnswers()[0].answerId}" class="radioButton" /> <label for="questionAnswer['${partnerOpt.questionId}']" class="formLabel pad20Right">Yes</label> <input type="radio" name="questionAnswer['${partnerOpt.questionId}']" class="radioButton" value="${partnerOpt.getAnswers()[1].answerId}" /> <label for="questionAnswer['${partnerOpt.questionId}']" class="formLabel">No</label> </div> <div id="optInError" class="formError" style="display:none;">Oops... your request did not go through, please try again.</div> <div class="pad15Top"> <a href="javascript:submitOptIn();"><img src="images/theme/btn_opt_in_submit.gif"/></a> </div> </form> <script type="text/javascript"> function submitOptIn() { $('optInError').hide(); dataString = $('#partnerOptIn').serialize(); $.ajax({ data: dataString, url: "partnerOpt.do", timeout: 30000, type: "POST", success: function(html){ var newHtml = "<h4>Thank you</h4><p>We appreciate your time to respond to our request.</p>"; $('#optInContent').html(newHtml); }, */trying this code for sucess is throwing me an error /* <!-- buttonpressed function--> success: function(html){ $('#optInContent').html(${buttonPressed}); }, <!-- buttonpressed function--> error: function(){ $('#optInError').show(); } }); } </script>

  • jQuery effect on iframe parent document

    Just wondering if anyone else has experienced this or knows why I am getting an error. I'm using javascript from within an iframe to call a parent dom element then use jQuery UI's effect core to shake it. Here is an example: $(document).ready(function(){ if ($("form").length>0) { $("form").submit(function(){ var oParentDoc = $(parent.document).find("div#element"); var action = $(this).attr("action"); var postdata = $(this).serialize(); $(oParentDoc).addClass("loading"); $.post(action,postdata,function(data){ $(oParentDoc).removeClass("loading").effect("shake",{"times":3,"distance":10},60); }); return false; }); } }); It works without the effect, but when I use an effect it gives me this error: uncaught exception: [Exception...

  • Intermittent "No Database Selected" in PHP/MySQL?

    Have a PHP/MySQL form with a dropdown box containing a list of 350 names. When any random name is selected, sometimes it works & displays info about that name from the database, and sometimes the form gives the error "No Database Selected". Here's what I've tried, pretty much grasping at straws as I'm not a programmer: Increasing max_connections in /etc/my.cnf from 200 to 2000 (even though only 4-5 connections are made and it's a lightly used server) Changing mysql_pconnect to mysql_connect Adding the word true to this connection string: $mysql = mysql_pconnect($hostname_mysql, $username_mysql, $password_mysql, true) or trigger_error(mysql_error(),E_USER_ERROR); Changing the word require_once to require on this line: [?php require('/home/user/Connections/mysql.php'); ?] Enabling MySQL & PHP query & error logging. (no errors logged) Here is the code: [removed old bad code] Update: Working answer from Rob Apodaca below.

  • Actionscript base class in Flex AIR app

    - by Alan
    I'm trying to build a Flex AIR app using Flex Builder 3, which I'm just getting started with. In Flash CS4, there's a text field in the authoring environment where you can specify a class that will become the "base" class - your class inherits from Sprite and then "becomes" the Stage at runtime. Is there a a way to do the same thing with Flex/AIR? Failing that, can anyone explain how to create and use an external class? Originally I had this in TestApp.mxml: <?xml version="1.0" encoding="utf-8"?> <mx:WindowedApplication xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute"> <mx:Script source="TestApp.as"/> </mx:WindowedApplication> And this in TestApp.as: package { public class TestApp { public function TestApp() { trace('Hello World'); } } } That gives the error "packages cannot be nested", so I tried taking out the package statement: public class TestApp { public function TestApp() { trace('Hello World'); } } That gives an error "classes cannot be nested", so I finally gave up and tried to take out the class altogether, figuring I'd try to start with a bunch of functions instead: function init() { trace('Hello World'); } But that gives the error "A file found in a source-path must have an externally visible definition. If a definition in the file is meant to be externally visible, please put the definition in a package". I can't win! When I put my class in a package, it says I can't do that because it would be nested. When I don't, it says it needs to be in a package so it can be seen. Does anyone know how to fix this? If I can't do the custom-class-as-base-class thing, is there a way I could just have it like: <?xml version="1.0" encoding="utf-8"?> <mx:WindowedApplication xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute"> <mx:Script source="TestApp.as"/> <mx:Script> var app = new TestApp(); </mx:Script> </mx:WindowedApplication> At the moment I can't import the class definition at all, so even that won't work.

I'm then trying to iterate over that array and resize them all to a fixed size (150x150) I'm doing it this way: for(int i = 0; i< this->numTrainingFaces; i++) { IplImage* frame_copy = cvCreateImage( cvSize(150,150), this->faceImageArray[0]->depth, this->faceImageArray[0]->nChannels ); cout << "Created image" << endl; cvResize(this->faceImageArray[i], frame_copy); cout << "Resized image" << endl; IplImage* grey_image = cvCreateImage( cvSize( frame_copy->width, frame_copy->height ), IPL_DEPTH_8U, 1 ); cout << "Created grey image" << endl; cvCvtColor( frame_copy, grey_image, CV_RGB2GRAY ); cout << "Converted image" << endl; this->faceImageArray[i] = grey_image; cvReleaseImage(&frame_copy); cvReleaseImage(&grey_image); } But I'm getting this output, and I'm not sure why: Created image Resized image Created grey image Converted image Created image OpenCV Error: Assertion failed (src.type() == dst.type()) in cvResize, file /build/buildd/opencv-2.1.0/src/cv/cvimgwarp.cpp, line 3102 terminate called after throwing an instance of 'cv::Exception' what(): /build/buildd/opencv-2.1.0/src/cv/cvimgwarp.cpp:3102: error: (-215) src.type() == dst.type() in function cvResize Aborted I'm basically just trying to replace the image in the array with the resized one in as few steps as possible. Edit: Revised my code as follows: for(int i = 0; i< this->numTrainingFaces; i++) { IplImage* frame_copy = cvCreateImage( cvSize(150,150), this->faceImageArray[i]->depth, this->faceImageArray[i]->nChannels ); cvResize(this->faceImageArray[i], frame_copy); IplImage* grey_image = cvCreateImage( cvSize( frame_copy->width, frame_copy->height ), IPL_DEPTH_8U, 1 ); cvCvtColor( frame_copy, grey_image, CV_RGB2GRAY ); faceImageArray[i] = cvCreateImage( cvSize(grey_image->width, grey_image->height), grey_image->depth, grey_image->nChannels); cvCopy(grey_image,faceImageArray[i]); cvReleaseImage(&frame_copy); cvReleaseImage(&grey_image); } Then later on I'm performing some PCA, and get this output: OpenCV Error: Null pointer (Null pointer to the written object) in cvWrite, file /build/buildd/opencv-2.1.0/src/cxcore/cxpersistence.cpp, line 4740 But I don't think my code has got to the point where I'm explicitly calling cvWrite, so it must be part of the library. I can give a full implementation if necessary - is there anything in my code that's going to create a null pointer?
