• Send Confirmation Email with Google Forms / Spreadsheets

  - by bozdoz

  I know that Google Spreadsheets includes a mass mailout option with its MailApp.sendEmail function, but, as far as I know, it can only run once a form is opened, or by manually clicking "run". I have a Google form which includes an area for someone to put their email address. Is there a simple solution to send this data to its Google Spreadsheet and send it as a confirmation to the specified email address? It would be great if I could somehow incorporate MailApp.sendEmail into the form, instead of into the spreadsheet (which would be after the fact and manual, instead of instant and automatic). Also, note that I will be posting with jQuery. Any ideas?

• Html dynamically repeated border-image

  - by Clox

  I have a table which border I want to have a sort of zig-zag shape. I want the table to have an automatic size; resizing depending on how big the browser is. But rrathe than just having an image that gets stretched I want a seamless image that gets repeat instead. I found out this can be done with CSS3's Border-image but by looking and Browser Statistics I can see than only about half of all the viewers will be able to see it since no version of IE does yet support it. So I'm looking for an alternate method. What would be the best way of doing it? Thanks in advance!

• Why can't I retrieve the entities I've just persisted?

  - by felipecao

  I've got this web service that basically queries the database and returns all persisted entities. For testing purposes, I've created a TestDataManager that persists 2 example entities after Spring context is loaded (BTW, I'm using JAX-WS, Spring, Hibernate and HSQLDB). My TestDataManager looks like this: @Component public class TestDataManager { @Resource private SessionFactory sf; @PostConstruct @Transactional(readOnly = false, propagation = Propagation.REQUIRES_NEW) public void insertTestData(){ sf.openSession(); sf.openSession().beginTransaction(); sf.openSession().persist(new Site("site one")); sf.openSession().persist(new Site("site two")); sf.openSession().flush(); } } My JAX-WS endpoint looks like this: @WebService public class SmartBrickEndpoint { @Resource private WebServiceContext context; public Set<Site> getSitesForUser(String user){ return getSiteService().findByUser(new User(user)); } private ISiteService getSiteService(){ ServletContext servletContext = (ServletContext) context.getMessageContext().get("javax.xml.ws.servlet.context"); return (ISiteService) BeanRetriever.getBean(servletContext, ISiteService.class); } } This my Service class: @Component @Transactional(readOnly = true) public class SiteService implements ISiteService { @Resource private ISiteDao siteDao; @Override public Set<Site> findByUser(User user) { return siteDao.findByUser(user); } } This is my DAO: @Component @Transactional(readOnly = true) public class SiteDao implements ISiteDao { @Resource private SessionFactory sessionFactory; @Override public Set<Site> findByUser(User user) { Set<Site> sites = new LinkedHashSet<Site>(sessionFactory.getCurrentSession().createCriteria(Site.class).list()); return sites; } } This is my applicationContext.xml: <context:annotation-config /> <context:component-scan base-package="br.unirio.wsimxp.dao"/> <context:component-scan base-package="br.unirio.wsimxp.service"/> <context:component-scan base-package="br.unirio.wsimxp.spring"/> <bean id="applicationDS" class="org.springframework.jdbc.datasource.DriverManagerDataSource"> <property name="driverClassName" value="org.hsqldb.jdbcDriver"/> <property name="url" value="jdbc:hsqldb:file:sites"/> </bean> <bean id="sessionFactory" class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean"> <property name="dataSource" ref="applicationDS" /> <property name="configLocation"> <value>classpath:hibernate.cfg.xml</value> </property> <property name="hibernateProperties"> <props> <prop key="hibernate.dialect">org.hibernate.dialect.HSQLDialect</prop> <prop key="hibernate.show_sql">true</prop> <prop key="hibernate.format_sql">true</prop> <prop key="hibernate.connection.release_mode">on_close</prop> <!--<prop key="hibernate.current_session_context_class">thread</prop>--> <prop key="hibernate.query.factory_class">org.hibernate.hql.classic.ClassicQueryTranslatorFactory</prop> <prop key="hibernate.hbm2ddl.auto">create-drop</prop> </props> </property> </bean> <bean id="transactionManager" class="org.springframework.orm.hibernate3.HibernateTransactionManager"> <property name="sessionFactory" ref="sessionFactory" /> </bean> <tx:annotation-driven transaction-manager="transactionManager" /> This is what's going on now: when the app is deployed, TestDataManager#insertTestData kicks-in (due to @PostConstruct) and persist does not raise any exception. I should have 2 entities in the DB by now. Afterwards, I invoke the endpoint by a SOAP client, and the request goes all the way up to the DAO. The Hibernate invocation does not raise any exception, but the returned list is empty. The odd thing is, in TestDataManager, if I switch from sf.openSession() to sf.getCurrentSession(), I get an error message: "No Hibernate Session bound to thread, and configuration does not allow creation of non-transactional one here". What I am doing wrong here? Why is the query "not seeing" the persisted entities? Why do I need to invoke sf.openSession() on TestDataManager although it's annotated with @Transactional? I have done some tests with hibernate.current_session_context_class=thread in application.xml, but then I just switch problems in each class. I'd like not needing to manually invoke sf.openSession() and leave that for Hibernate to take care. Thanks a lot for any help!

• How can I dereference a hashref constant?

  - by makenai

  Let's say I have a hashref constant like the following: use constant DOGS => { Lassie => 'collie', Benji => 'mutt', Scooby => 'great dane', Goofy => '???' }; How can I dereference it properly to get say.. they keys out of it? warn ref DOGS; # HASH at untitled line 12. warn keys( %{DOGS} ); # Warning: something's wrong (empty list) warn keys( DOGS ); # Type of arg 1 to keys must be hash (not constant item) The following is the only way I can seem to make it work: my $dogs = DOGS; warn keys( %$dogs ); # LassieBenjiGoofyScooby at untitled line 15. What am I doing wrong?

• Efficient storage/retrieval method for replayable comet style applications (Google Wave, Etherpad)

  - by Gareth Simpson

  I am considering a web application that would have the same kind of multi user, automatic saving, infinite undo / replay capabilities that you see in Google Wave and Etherpad (albeit on a drastically smaller scale and userbase). Before I go away and reinvent the wheel, is this something that has already been addressed as either a piece of technology or library, or even just a design pattern. I know this isn't necessarily the best Stack Overflow question as there is probably not a "right" answer, but my Google-fu has failed me and I'd just like a reading list! Ordinarily I would be developing under python/django but this is not a firm requirement just a preference :)

• Passing objects by reference or not in C#

  - by Piku

  Suppose I have a class like this: public class ThingManager { List<SomeClass> ItemList; public void AddToList (SomeClass Item) { ItemList.Add(Item); } public void ProcessListItems() { // go through list one item at a time, get item from list, // modify item according to class' purpose } } Assume "SomeClass" is a fairly large class containing methods and members that are quite complex (List<s and arrays, for example) and that there may be a large quantity of them, so not copying vast amounts of data around the program is important. Should the "AddToList" method have "ref" in it or not? And why? It's like trying to learn pointers in C all over again ;-) (which is probably why I am getting confused, I'm trying to relate these to pointers. In C it'd be "SomeClass *Item" and a list of "SomeClass *" variables)

• Passing parameters into ViewModels (Prism)

  - by vXtreme

  Hi I can't figure out how to pass parameters to my viewmodels from other views or viewmodels. For instance, I have a View called Customers. There is a grid inside, and if you double-click the grid, a new view is supposed to come up and allow you to edit that customer's data. But how will the View(Model) responsible for editing data know which customer it's supposed to open if I can't pass any parameters inside? EventAggregator is out of the question because I obviously can't create hundreds of eventargs, each for one view. And besides, it's a lousy solution. So far I was able to come up with: CustomerDataView custView = new CustomerDataView(customerId, currentContext); manager.Regions[RegionNames.Sidebar].AddAndActivate(custView); What do you think about this particular solution? Is this the way it's normally done? What I don't like about this is the fact that I lose out on automatic dependency injection by Unity.

• sharepoint online quick launch

  - by Brian

  Hello, we are converting from sharepoint 2003 to sharepoint on line. I am having trouble reproducing a specific behavior in the online version. If a choose a list, I get a "select a view" navigation on the left hand side of the page showing the available views. When a new view is created, it automatically appears on this navigation list. In the online sharepoint, instead there is a view dropdown. I know I can manually setup links on the quick launch but I'm looking for an automatic way to do this. Can the online sharepoint be set up so that when views are added they automatically appear as left-hand links? Or can the "views" dropdown be moved to the left side which would be an acceptable work around? Please note I am unfamiliar with SP designer and I do work with .NET but I dont want to go that route just for this issue - thanks.

• Is there a way to increase the efficiency of shared_ptr by storing the reference count inside the co

  - by BillyONeal

  Hello everyone :) This is becoming a common pattern in my code, for when I need to manage an object that needs to be noncopyable because either A. it is "heavy" or B. it is an operating system resource, such as a critical section: class Resource; class Implementation : public boost::noncopyable { friend class Resource; HANDLE someData; Implementation(HANDLE input) : someData(input) {}; void SomeMethodThatActsOnHandle() { //Do stuff }; public: ~Implementation() { FreeHandle(someData) }; }; class Resource { boost::shared_ptr<Implementation> impl; public: Resource(int argA) explicit { HANDLE handle = SomeLegacyCApiThatMakesSomething(argA); if (handle == INVALID_HANDLE_VALUE) throw SomeTypeOfException(); impl.reset(new Implementation(handle)); }; void SomeMethodThatActsOnTheResource() { impl->SomeMethodThatActsOnTheHandle(); }; }; This way, shared_ptr takes care of the reference counting headaches, allowing Resource to be copyable, even though the underlying handle should only be closed once all references to it are destroyed. However, it seems like we could save the overhead of allocating shared_ptr's reference counts and such separately if we could move that data inside Implementation somehow, like boost's intrusive containers do. If this is making the premature optimization hackles nag some people, I actually agree that I don't need this for my current project. But I'm curious if it is possible.

• Why do I get CA1811 when I call a private method from a public method in C++/CLI?

  - by brickner

  I've recently upgraded my project from Visual Studio 2008 to Visual Studio 2010. By enabling Code Analysis and building on Release, I'm getting warning CA1811: Avoid uncalled private code. I've managed to reduce the code to this: .h file: public ref class Foo { public: virtual System::String^ ToString() override; private: static System::String^ Bar(); }; .cpp file: String^ Foo::ToString() { return Bar(); } String^ Foo::Bar() { return "abc"; } The warning I get: CA1811 : Microsoft.Performance : 'Foo::Bar(void)' appears to have no upstream public or protected callers. It doesn't matter if Bar() is static or not. I've tried to reproduce it in C# but I can't. I can only reproduce it in C++/CLI. Why do I get this warning? Is this a Visual Studio 2010 bug?

• Visual Studio 2010 "Not enough storage is available to process this command"

  - by Daniel Perez

  I'm fighting with VS 2010 and this error that seems to be very common in previous versions, but it looks like not everyone is having it in the latest version. I've got VS 2010 SP1 and I'm getting this error quite often. The problem is that it's not even enough to restart VS in order to make it go away, I usually have to restart my pc, and i'm losing a lot of time doing this (it's quite frequent) I've got Windows 7 32bits (can't upgrade to 64 bits, the company doesn't allow it), and I can't do things like creating another solution (please don't reply this :) ) I've used the command to make devenv.exe LARGEADDRESSAWARE, but the error keeps on happening My virtual memory size is set to automatic, and the weird thing is that VS doesn't even take 2gb of ram, so I don't know if the error is really because it's lacking memory, or if it's some bug in the program any ideas, things to try, something?

• Perl latin-9? Unicode - need to add support

  - by Phill Pafford

  I have an application that is being expanded to the UK and I will need to add support for Latin-9 Unicode. I have done some Googling but found nothing solid as to what is involved in the process. Any tips? Here is some code (Just the bits for Unicode stuff) use Unicode::String qw(utf8 latin1 utf16); # How to call $encoded_txt = $self->unicode_encode($item->{value}); # Function part sub unicode_encode { shift() if ref($_[0]); my $toencode = shift(); return undef unless defined($toencode); Unicode::String->stringify_as("utf8"); my $unicode_str = Unicode::String->new(); # encode Perl UTF-8 string into latin1 Unicode::String # - currently only Basic Latin and Latin 1 Supplement # are supported here due to issues with Unicode::String . $unicode_str->latin1( $toencode ); ... Any help would be great and thanks.

• How to enforce users to create objects of class derived from mine with "new" only?

  - by sharptooth

  To implement reference counting we use an IUnknown-like interface and a smart pointer template class. The interface has implementation for all the reference-count methods, including Release(): void IUnknownLike::Release() { if( --refCount == 0 ) { delete this; } } The smart pointer template class has a copy constructor and an assignment operator both accepting raw pointers. So users can do the following: class Class : public IUnknownLike { }; void someFunction( CSmartPointer<Class> object ); //whatever function Class object; someFunction( &object ); and the program runs into undefined behavior - the object is created with reference count zero, the smart pointer is constructed and bumps it to one, then the function returns, smart pointer is destroyed, calls Release() which leads to delete of a stack-allocated variable. Users can as well do the following: struct COuter { //whatever else; Class inner;// IUnknownLike descendant }; COuter object; somefunction( &object.Inner ); and again an object not created with new is deleted. Undefined behavior at its best. Is there any way to change the IUnknownLike interface so that the user is forced to use new for creating all objects derived from IUnknownLike - both directly derived and indirectly derived (with classes in between the most derived and the base)?

• where is everything in django admin?

  - by FurtiveFelon

  Hi all, I would like to figure out where everything is in django admin. Since i am currently trying to modify the behavior rather heavily right now, so perhaps a reference would be helpful. For example, where is ModelAdmin located, i cannot find it anywhere in C:\Python26\Lib\site-packages\django\contrib\admin. I need that because i would like to look at how it is implemented so that i can override with confidence. I need to do that in part because of this page: http://docs.djangoproject.com/en/dev/ref/contrib/admin/#modeladmin-methods, for example, i would like to override ModelAdmin.add_view, but i can't find the original source for that. As well as i would like to see the url routing file for admin, so i can easily figure out which url corresponding to which template etc. Thanks a lot for any pointers!

• Blogger Code Image linking to post page

  - by Jm Agas

  Is this possible to achieve in blogger? My goal is to make Static page images to become clickable and link it to the actual post page. I know its possible by editing each post but I want to make it automatic. For example: In 9gag.com when you click the image from the homepage it will actually link you to the post page. I want to do the same but in blogger. Something like this <b:if cond='data:blog.pageType != &quot;static_page&quot;'><a expr:href='data:post.url'><static page images></a></b:if> Screenshot: http://i.stack.imgur.com/YAWkL.jpg

• Dynamic domain methods missing from grails service when injected into java service in grails app.

  - by Gordon C

  I had the idea that I would write my GroovyDao as a grails service. Next I would write a MyJavaService in java and locate it in the java sources dir in my grails app. MyJavaService contains a instance reference to groovyDao for spring injection. I would wire up in resources.groovy the MyJavaService with a groovyDao = ref("GroovyDao"). Everything starts up fine. However if I make call to MyJavaService any Domain method like Domain.list() returns a Method not found error. Any help is appreciated.

• Facebook javascript in address bar, possible to replicate?

  - by DoMx

  This is my first experience with stackoverflow and I'm afraid my question asks of a lot for a first. I was looking at this thread: http://stackoverflow.com/questions/2634159/javascrypt-in-the-adress-bar-is-this-malicious and as you will see SLaks has very kindly deobfuscated the javascript and left us with what appears as the Javascript behind the automatic facebook invite code. As I'm fairly new to javascript, I was wondering, what other components were needed to get this code to work? You of course have the functions there and they are called by the obfuscated javascript but how exactly? Would it be possible to replicate this on a page of my own using the information available or is there more to this script I am missing? I am willing to financially assist somebody who could compile a solution for me. Thank you in advance.

• DataBind and Postback

  - by Michael La Voie

  This is a general how does DataBind work questions... I have a simple page with a GridView that is bound (in the aspx code) to an ObjectDataSource. I can look in the Select() function called by the ObjectDataSource to see that it is called on the initial load and on every post back. I have some logic that happens on post backs that will affect the GridView's data, and I want to call GridView.DataBind() later on in the post back, after I've made some changes. Is there a way to prevent the automatic rebinding that happens on each post back? Does this mean I can't use an ObjectDataSource for this control?

• wanting a good memory + disk caching solution

  - by brofield

  I'm currently storing generated HTML pages in a memcached in-memory cache. This works great, however I am wanting to increase the storage capacity of the cache beyond available memory. What I would really like is: memcached semantics (i.e. not reliable, just a cache) memcached api preferred (but not required) large in-memory first level cache (MRU) huge on-disk second level cache (main) evicted from on-disk cache at maximum storage using LRU or LFU proven implementation In searching for a solution I've found the following solutions but they all miss my marks in some way. Does anyone know of either: other options that I haven't considered a way to make memcachedb do evictions Already considered are: memcachedb best fit but doesn't do evictions: explicitly "not a cache" can't see any way to do evictions (either manual or automatic) tugela cache abandoned, no support don't want to recommend it to customers nmdb doesn't use memcache api new and unproven don't want to recommend it to customers

• Sudoku Recursion Issue (Java)

  - by SkylineAddict

  I'm having an issue with creating a random Sudoku grid. I tried modifying a recursive pattern that I used to solve the puzzle. The puzzle itself is a two dimensional integer array. This is what I have (By the way, the method doesn't only randomize the first row. I had an idea to randomize the first row, then just decided to do the whole grid): public boolean randomizeFirstRow(int row, int col){ Random rGen = new Random(); if(row == 9){ return true; } else{ boolean res; for(int ndx = rGen.nextInt() + 1; ndx <= 9;){ //Input values into the boxes sGrid[row][col] = ndx; //Then test to see if the value is valid if(this.isRowValid(row, sGrid) && this.isColumnValid(col, sGrid) && this.isQuadrantValid(row, col, sGrid)){ // grid valid, move to the next cell if(col + 1 < 9){ res = randomizeFirstRow(row, col+1); } else{ res = randomizeFirstRow( row+1, 0); } //If the value inputed is valid, restart loop if(res == true){ return true; } } } } //If no value can be put in, set value to 0 to prevent program counting to 9 setGridValue(row, col, 0); //Return to previous method in stack return false; } This results in an ArrayIndexOutOfBoundsException with a ridiculously high or low number (+- 100,000). I've tried to see how far it goes into the method, and it never goes beyond this line: if(this.isRowValid(row, sGrid) && this.isColumnValid(col, sGrid) && this.isQuadrantValid(row, col, sGrid)) I don't understand how the array index goes so high. Can anyone help me out?

• Getting the ranking of a photo in SQL

  - by Jake Petroules

  I have the following tables: Photos [ PhotoID, CategoryID, ... ] PK [ PhotoID ] Categories [ CategoryID, ... ] PK [ CategoryID ] Votes [ PhotoID, UserID, ... ] PK [ PhotoID, UserID ] A photo belongs to one category. A category may contain many photos. A user may vote once on any photo. A photo can be voted for by many users. I want to select the ranks of a photo (by counting how many votes it has) both overall and within the scope of the category that photo belongs to. The count of SELECT * FROM Votes WHERE PhotoID = @PhotoID being the number of votes a photo has. I want the resulting table to have generated columns for overall rank, and rank within category, so that I may order the results by either. So for example, the resulting table from the query should look like: PhotoID VoteCount RankOverall RankInCategory 1 48 1 7 3 45 2 5 19 33 3 1 2 17 4 3 7 9 5 5 ... ...you get the idea. How can I achieve this? So far I've got the following query to retrieve the vote counts, but I need to generate the ranks as well: SELECT PhotoID, UserID, CategoryID, DateUploaded, (SELECT COUNT(CommentID) AS Expr1 FROM dbo.Comments WHERE (PhotoID = dbo.Photos.PhotoID)) AS CommentCount, (SELECT COUNT(PhotoID) AS Expr1 FROM dbo.PhotoVotes WHERE (PhotoID = dbo.Photos.PhotoID)) AS VoteCount, Comments FROM dbo.Photos

• Parsing multiple files at a time in Perl

  - by sfactor

  I have a large data set (around 90GB) to work with. There are data files (tab delimited) for each hour of each day and I need to perform operations in the entire data set. For example, get the share of OSes which are given in one of the columns. I tried merging all the files into one huge file and performing the simple count operation but it was simply too huge for the server memory. So, I guess I need to perform the operation each file at a time and then add up in the end. I am new to perl and am especially naive about the performance issues. How do I do such operations in a case like this. As an example two columns of the file are. ID OS 1 Windows 2 Linux 3 Windows 4 Windows Lets do something simple, counting the share of the OSes in the data set. So, each .txt file has millions of these lines and there are many such files. What would be the most efficient way to operate on the entire files.
