  • compiling boost based application using cron

    - by user303544
    Hi All, I am building some boost based application for various embedded targets. I have developed a script which can build my application with different toolchain for several targets. This script works fine when I run it from command line but if it is invoked from cron it always fails to link the object files. My application has dependency on openssl. Can anyone please give some idea? What would be the root cause of this kind of behavior? Thanks in advance.

  • Grails external Jms broker (active mq)

    - by TheBigS
    I have what will become an 'external' activemq server I'd like grails to be able to talk to. Right now I am just running it on my dev box. Here is what I have setup right now: 1) Run activemq server 2) Run activemq/examples using ant to produce messages 3) View ActiveMQ admin site: http://localhost:8161/admin/queues.jsp verify that messages are in the queue. 4) Follow Mini Tutorial to create the Service and Controller: http://www.grails.org/ActiveMQ+Plugin 5) Configured my Grails resources.groovy file as follows: beans = { jmsConnectionFactory(SingleConnectionFactory){ targetConnectionFactory = { ActiveMQConnectionFactory cf -> brokerURL = 'tcp://localhost:61616' } } } When I run the grails app I get a BindException saying port 61616 is already in use. How do I configure this to use my server that is already running? I've tried changing 'localhost' to '127.0.0.1' and to my LAN ip, but no luck, it keeps trying to setup its own embedded activemq server. Any ideas?

  • Problem when using \LaTeX \includegraphics with some PDF files

    - by brandstaetter
    I noticed some strange effects when including existing pdf graphics in my laTeX documents: Most file work flawlessly, but some PDFs that were created on a different machine (or from the web) cause the whole page on which they are embedded to become ever-so-slightly distorted. I only notice the difference in a side-by-side comparison, but once you see it, it's obvious. The text layout seems slightly broken, and when you zoom in you can see it better. I will try to make some screenshots to further elaborate, but in the meantime: Has anyone seen this before and how can I get rid of these distortions?

  • ExtJS panel does not render properly unless I open Firebug - WTF?

    - by Huuuze
    I have the following ExtJS Panel embedded in another Panel, which then resides in a TabPanel and the TabPanel is in a FormPanel. With that being said, these start/end date fields are initially displayed in very small cells -- the cells are so small that I see horizontal scroll bars. Now here's the weird part: if I open Firebug, everything pops into place. Does anyone know what's going on? Why isn't it rendering properly in the first place and why does Firebug cause everything to work properly simply by opening Firebug? var dateFields = new Ext.Panel({ id: 'dateFields', labelAlign: 'bottom', border: false, items: [{ layout: 'column', defaults: { columnWidth: 0.5 }, items: [{ layout: 'form', border: false, items: [{ xtype: 'datefield', name: 'start_date', fieldLabel: 'Start Date' }] }, { layout: 'form', border: false, items: [{ xtype: 'datefield', name: 'end_date', fieldLabel: 'End Date' }] }] }] });

  • Could not find any resources appropriate for the specified culture or the neutral culture.

    - by Captain Comic
    I have created an assembly and later renamed it. Then i started getting runtime errors when calling toolsMenuName = resourceManager.GetString(resourceName); The resourceName variable is "enTools" at runtime. Could not find any resources appropriate for the specified culture or the neutral culture. Make sure "Jfc.TFSAddIn.CommandBar.resources" was correctly embedded or linked into assembly "Jfc.TFSAddIn" at compile time, or that all the satellite assemblies required are loadable and fully signed. The code: string resourceName; ResourceManager resourceManager = new ResourceManager("Jfc.TFSAddIn.CommandBar", Assembly.GetExecutingAssembly()); CultureInfo cultureInfo = new CultureInfo(_applicationObject.LocaleID); if(cultureInfo.TwoLetterISOLanguageName == "zh") { System.Globalization.CultureInfo parentCultureInfo = cultureInfo.Parent; resourceName = String.Concat(parentCultureInfo.Name, "Tools"); } else { resourceName = String.Concat(cultureInfo.TwoLetterISOLanguageName, "Tools"); } // EXCEPTION IS HERE toolsMenuName = resourceManager.GetString(resourceName); I can see the file CommandBar.resx included in the project, i can open it and can see the "enTools" string there.

  • In the meantime, to be or not to be ... productive!

    - by Jan Kuboschek
    I just moved back to Europe from the US after living there for 7 years. Apart from major adjustment issues, I'm currently looking for a job over here. I'm mainly interested in (IT) Consulting and, since these jobs typically require programming knowledge, such as Java, I'm trying to think of something productive to write (perhaps to demo my skills) while I'm waiting for my interviews (starting in two weeks. Folks here are a bit slower than in the US apparently...). I graduated from college about a year and a half ago and have a 4 year degree in international management/economics and about 3/4 of a 2 year degree in computer science finished. I've written my fair share of web software over the years, but nothing concrete that I could show, especially not in Java. Now, I've never had the problem of not having any idea what to write. Basic games I could write, but I'm not sure how well that'll come over when I walk into my interview and say "hey, I was bored. Take a look at my multiplayer space invaders game! Wanna try beating me??". Any thoughts? I browsed SourceForge the other day to find a nice little project to contribute to, but decided that I don't want to commit to someone else's project at this time. Any ideas, perhaps from someone who has been, or currently is, in a similar position would be much appreciated. Oh, and lastly: Instead of developing a program or two to demonstrate my skills, I could spend my time brushing up on UML and Perl. Any suggestions regarding that? Writing a demo vs. learning something new?

  • How can I set breakpoints in an external JS script in Firebug

    - by Manu
    I can easily set breakpoints in embedded JS functions, but I don't see any way of accessing extarnal JS scripts via Firebug unless I happen to enter them during a debug session. Is there a way to do this w/o having to 'explore' my way into the script? @Jason: This is a good point, but in my case I do not have easy access to the script. I am specifically talking about the client scripts which are invoked by the ASP.Net Validators that I would like to debug. I can access them during a debug session through entering the function calls, but I could not find a way to access them directly.

  • InfoPath Getting SharePoint Group Information

    - by anon
    I have an InfoPath form embedded in an aspx page on a SharePoint site. How do I bind the SharePoint user groups to a drop-down list on my form? What I've tried so far is to create a data connection to a web service (method GetGroupCollectionFromWeb) to pull the data. Next, I open the list box properties, select "Look up values from an external data source", select the data source, assign the entries, and I get the following error: "You must select a repeating group or field." What I don't understand is that since the method I am calling is called GetGroupCollectionFromWeb, isn't the return value a collection? And aren't collections repeating by definition? What am I missing, and is there a workaround? Thank you.

  • Hide div based on url

    - by Ghetto Styles
    Sorry if this is another repost. I have been attempting to find a solution but nothing works that I have tried. I am using a blog which I have full html control over. I can usually find my way around basic html but when it comes to Java or CSS I am a complete newb. Sorry, I know absolutely nothing. Now that that is out of the way. I have two sidebar div's that I am trying to hide on one specific url to utilize more space for a content iframe. This is one of the coded I have tried to use which doesn't seem to work or I am missing something. <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> <html> <head> <script language="text/javascript" <?php &#36;(function(){ if (window.location.search === "mywebsite/Videos.html") { &#36;('#navleft').hide(); } else { &#36;('#navleft').show(); } }); ?> </script> Please remember I do not know anything when it comes to php or java. I want to do this for both #navright and #navleft. Also this is in the CSS section. Thanks for any help!! #navright{ width: 200px; } #navleft{ width: 200px; } #content{ margin:0px; }

  • Advice Needed on Development of ConnectionWizard Custom Control

    - by SidC
    I have the need for an ASP.NET custom server control that will check the web.config file for a connectionstring name, prompt the user to create said connectionstring if not present, and execute create table stored procedures using the connection. This control will be embedded into a webpart for use in a WSS3.0 solution. Can anyone suggest some good tutorials on creating this type of control - specifically addressing use of connectionstrings? What methods/classes do I need to setup? Should I use the p&p data application block for this project? Thanks, Sid

  • Sending images using Http Post

    - by primal
    I want to send an image from the android client to the Django server using Http Post. The image is chosen from the gallery. At present, I am using list value name Pairs to send the necessary data to the server and receiving responses from Django in JSON. Can the same approach be used for images (with urls for images embedded in JSON responses)? Also which of, accesssing images remotely without downloading them from the server or downloading and storing them in a Bitmap array and using them locally is a better method? The images are few in number (<10) and small in size (50*50 dip). Any tutorial to tackle these problems would be much appreciated.

  • Printing python tkinter output

    - by Eric
    I am trying to print the contents of a python tkinter canvas. I have tried using the postscript method of canvas to create a postscript file, but I get a blank page. I know this is because I have embedded widgets, and these do not get rendered by the postscript method. Before I rewrite my program to create a more printer-friendly layout, can someone suggest a way to approach this problem? All of the programming books I have ever read approach the problem of sending output to a printer with a bit of hand-waving, something along the lines of: "It's a difficult problem that depends on interacting with the operating system." I also have a hard time finding resources about this because of all the pages related to printing to the screen. I am using Python 2.6, on Ubuntu 9.04.

  • Documentation for installing and running hadoop 2.2 on Windows

    - by user2325154
    With the latest release of Hadoop 2.2 I see that the release notes mentions that this version has significant improvements for running Hadoop on Windows. I downloaded Hadoop 2.2 yesterday and I saw lot of .cmd file alon with .sh files which ensures that this version has scripts and batch files for running Hadoop on Windows environment. However while looking at the Apache Hadoop documentation I couldn't find any step-by-step instructions on how to install and run this newer version on Windows. Besides this it looks like that the newer version has YARN architecture embedded in it and the old configurations provided on some of the tutorials online may be outdated and not applicable anymore. Is there any good documentation for Hadoop 2.2 available online ? I want it specifically for running Hadoop under Windows.

  • Hibernate CreateSQL Query Problem

    - by Shaded
    Hello All I'm trying to use hibernates built in createsql function but it seems that it doesn't like the following query. List =hibernateSession.createSQLQuery("SELECT number, location FROM table WHERE other_number IN (SELECT f.number FROM table2 AS f JOIN table3 AS g on f.number = g.number WHERE g.other_number = " + var + ") ORDER BY number").addEntity(Table.class).list(); I have a feeling it's from the nested select statement, but I'm not sure. The inner select is used elsewhere in the code and it returns results fine. This is my mapping for the first table: <hibernate-mapping> <class name="org.efs.openreports.objects.Table" table="table"> <id name="id" column="other_number" type="java.lang.Integer"> <generator class="native"/> </id> <property name="number" column="number" not-null="true" unique="true"/> <property name="location" column="location" not-null="true" unique="true"/> </class> </hibernate-mapping> And the .java public class Table implements Serializable { private Integer id;//panel_facility private Integer number; private String location; public Table() { } public void setId(Integer id) { this.id = id; } public Integer getId() { return id; } public void setNumber(Integer number) { this.number = number; } public Integer number() { return number; } public String location() { return location; } public void setLocation(String location) { this.location = location; } } Any suggestions? Edit (Added mapping)

  • Mapping many-to-many association table with extra column(s)

    - by user635524
    My database contains 3 tables: User and Service entities have many-to-many relationship and are joined with the SERVICE_USER table as follows: USERS - SERVICE_USER - SERVICES SERVICE_USER table contains additional BLOCKED column. What is the best way to perform such a mapping? These are my Entity classes @Entity @Table(name = "USERS") public class User implements java.io.Serializable { private String userid; private String email; @Id @Column(name = "USERID", unique = true, nullable = false,) public String getUserid() { return this.userid; } .... some get/set methods } @Entity @Table(name = "SERVICES") public class CmsService implements java.io.Serializable { private String serviceCode; @Id @Column(name = "SERVICE_CODE", unique = true, nullable = false, length = 100) public String getServiceCode() { return this.serviceCode; } .... some additional fields and get/set methods } I followed this example http://giannigar.wordpress.com/2009/09/04/m ... using-jpa/ Here is some test code: User user = new User(); user.setEmail("e2"); user.setUserid("ui2"); user.setPassword("p2"); CmsService service= new CmsService("cd2","name2"); List<UserService> userServiceList = new ArrayList<UserService>(); UserService userService = new UserService(); userService.setService(service); userService.setUser(user); userService.setBlocked(true); service.getUserServices().add(userService); userDAO.save(user); The problem is that hibernate persists User object and UserService one. No success with the CmsService object I tried to use EAGER fetch - no progress Is it possible to achieve the behaviour I'm expecting with the mapping provided above? Maybe there is some more elegant way of mapping many to many join table with additional column?

  • Checking servlet session attribute value in jsp file

    - by Marta
    I have a no framework java application. It consists of jsp files for view and servlets for the business logic. I must set the user session is the servlet with a firstName parameter. In the jsp file, I need to check if my firstName parameter has a value or not. If the firstName parameter is set, I need to display some html in the jsp file. If it is not set, I need to display different html in the jsp file. Servlet.java: HttpSession session = request.getSession(); session.setAttribute("firstName", customer.getFristName()); String url = "/index.jsp"; RequestDispatcher dispatcher = getServletContext().getRequestDispatcher(url); dispatcher.forward(request, response); header.jsp: // Between the <p> tags bellow I need to put some HTML with the following rules // If firstName exist: Hello ${firstName} <a href="logout.jsp">Log out</a> // Else: <a href="login.jsp">Login</a> or <a href="register.jsp">Register</a> <p class="credentials" id="cr"></p> What would be the best way to do this?

  • Embed form in another website - pitfalls

    - by Paddy
    Scenario: We provide a hosted site that clients pay to use internally (a tool to support their business workflow). We have a requirement to provide a form that the clients can 'embed' in their outward facing site. This form will permit a member of the public to enter some details to register an interest - this data will be pushed to our remote system. Question: I'm currently planning on creating a simple HTML page that the client's web guys can include in a simple fashion on their site (either using an iframe or an object tag). If I do this, am I going to run into difficulties when the user tries to submit the embedded form (as it will be going to different domain to the one they are currently browsing)? I had a look at google adsense and I see that they just provide a link to a JS file that renders their ads - I'm not sure I see the advantage in this, but if anybody has any bright ideas... Whatever technique that gets used, I'll have to authenticate the request as coming from my client's site(s).

  • SVN user guidelines

    - by Oliver Moran
    I have been tasked with writing a set of user guidelines for SVN for developers in my company. The guidelines are to be solely from a user perspective (e.g. commit comments, when to commit) and not from an administrative perspective (e.g. when to tag, how to structure). An administrative guideline will be written in a separate document. We are an app development house involved also in embedded development. So our developers range from HTML5 and Flash to Java and C. Some of our coding involves forking very large (millions of files) code bases. Other parts involve us engaging in ground-up development. Are there any best practices for use of SVN from a user (i.e. grunt developer) perspective?

  • Does ReleaseStringUTF do more than free memory?

    - by Bayou Bob
    Consider the following C code segments. Segment 1: char * getSomeString(JNIEnv *env, jstring jstr) { char * retString; retString = (*env)->GetStringUTFChars(env, jstr, NULL); return retString; } void useSomeString(JNIEnv *env, jobject jobj, char *mName) { jclass cl = (*env)->GetObjectClass(env, jobj); jmethodId mId = (*env)->GetMethodID(env, cl, mName, "()Ljava/lang/String;"); jstring jstr = (*env)->CallObjectMethod(env, obj, id, NULL); char * myString = getSomeString(env, jstr); /* ... use myString without modifing it */ free(myString); } Because myString is freed in useSomeString, I do not think I am creating a memory leak; however, I am not sure. The JNI spec specifically requires the use of ReleaseStringUTFChars. Since I am getting a C style 'char *' pointer from GetStringUTFChars, I believe the memory reference exists on the C stack and not in the JAVA heap so it is not in danger of being Garbage Collected; however, I am not sure. I know that changing getSomeString as follows would be safer (and probably preferable). Segment 2: char * getSomeString(JNIEnv *env, jstring jstr) { char * retString; char * intermedString; intermedString = (*env)->GetStringUTFChars(env, jstr, NULL); retString = strdup(intermedString); (*env)->ReleaseStringUTFChars(env, jstr, intermedString); return retString; } Because of our 'process' I need to build an argument on why getSomeString in Segment 2 is preferable to Segment 1. Is anyone aware of any documentation or references which detail the behavior of GetStringUTFChars and ReleaseStringUTFChars in relation to where memory is allocated or what (if any) additional bookkeeping is done (i.e. local Reference Pointer to the Java Heap being created, etc). What are the specific consequences of ignoring that bookkeeping. Thanks in advance.

  • python [lxml] - cleaning out html tags

    - by sadhu_
    from lxml.html.clean import clean_html, Cleaner def clean(text): try: cleaner = Cleaner(scripts=True, embedded=True, meta=True, page_structure=True, links=True, style=True, remove_tags = ['a', 'li', 'td']) print (len(cleaner.clean_html(text))- len(text)) return cleaner.clean_html(text) except: print 'Error in clean_html' print sys.exc_info() return text I put together the above (ugly) code as my initial forays into python land. I'm trying to use lxml cleaner to clean out a couple of html pages, so in the end i am just left with the text and nothing else - but try as i might, the above doesnt appear to work as such, i'm still left with a substial amount of markup (and it doesnt appear to be broken html), and particularly links, which aren't getting removed, despite the args i use in remove_tags and links=True any idea whats going on, perhaps im barking up the wrong tree with lxml ? i thought this was the way to go with html parsing in python?

  • Looking for a good C++/.net book

    - by Michael Minerva
    I have recently started to feel that I need to greatly improve my C++ skills especially in the realm of .net. I graduated from a good four year university with a degree in computer science about 9 months ago and I have since been doing full time contract work for a small software company in my local area. Most of my work has been done using Java/lisp/cocoa/XML and before that most of my programming in my senior year was in java/C#. I did a decent amount of C++ in my Sophomore year and in my free time before that but I feel that my general knowledge of C++/.net is very lacking for the opportunities that are now coming my way. Can anyone recommend a good book that could help me get up too speed? I feel I do not need a very basic introduction to C++ but something that covers the fundamentals of .net would be good for me. So basically what I need is a book or books that would be good for a .net novice and a C++ developer who is just beyond novice. Also, a book that would help bein an interview by giving me a conversional understanding of C++ would be great. Thanks a lot!.

  • How to define an array inside a function in C?

    - by Arunav Dev
    So in my source file I have the folowin function: void update(state* old_state, state* measurement, uint32_t size) { state new_state[size]; //some function using measurement and old_state and returning the result in newstate arm_fadd_32(measurement,old_state,newstate,size); // rest of the code } Now the compiler throws an error saying that error#28:expression must have a constant value. I think it's due to the fact that even though inside the method the size local variable is not changing the compiler is expecting a constant while defining the size. I have tried the following: int const a = size; and then tried to reinitialize it says constant value is not known. I did some research in internet and it appears that there is no easier way without using malloc, which I don't want to since I am using the code for some embedded application. Is there a way to avoid this problem without really using malloc? Thanks in advance guys!
