• java.util.Date.toString() is printing out wrong format

  - by pacoverflow

  The following code prints out "vmtDataOrig.creationdate=2012-11-03" VmtData vmtDataOrig = VmtDataDao.getInstance().loadVmt(1); System.out.println("vmtDataOrig.creationdate=" + vmtDataOrig.getCreationDate().toString()); Here is the definition of the creationDate field in the VmtData class: private Date creationDate = null; Here is the hibernate mapping of the creationDate field to the database table column: <property name="creationDate" column="CREATIONDATE" type="date"/> The CREATIONDATE column in the MySQL database table is of type "date", and for the record retrieved it has the value "2012-11-03". The Javadoc for the java.util.Date.toString() method says it is supposed to print the Date object in the form "dow mon dd hh:mm:ss zzz yyyy". Anyone know why it is printing it out in the form "yyyy-MM-dd"?

  I am trying to optimize this query. It is not slow for now but I am expecting a spike to hit this query in the near future. Is there anything else i can do to make this query faster? var posts = from p in context.post where p.post_isdeleted == false && p.post_parentid == null select new { p.post_date, p.post_id, p.post_titleslug, p.post_title, p.post_descriptionrender, p.userinfo.user_username, p.userinfo.user_userid, p.userinfo.user_GravatarHash, p.userinfo.user_points, p.category.catid, p.category.name, p.post_answercount, p.post_hasbestanswer, p.post_hits, p.post_isanonymous, p.post_votecount, FavoriteCount = context.favorites.Where(x => x.post.post_id == p.post_id).Count(), tags = from tg in context.posttag where tg.posttag_postid == p.post_id select new { tg.tag.tag_id, tg.tag.tag_title } };

  I am using OpenJPA 2.2.0 and when I am executing a select statement I am getting "Column index out of range, 0 < 1" error. EntityManager entityMgrObj = emf.getEntityManager(); entityMgrObj.clear(); Query query = entityMgrObj.createNativeQuery("select * from company_user where user_id = 1001); List<CompanyUserDO> companyUserDOObj = null; try { companyUserDOObj = query.getResultList(); } catch (Exception e) { System.out.println(e.getMessage()); } When the query.getResultList() executes I get "Column index out of range, 0 < 1" error.

• Need help with writing test

  - by London

  I'm trying to write a test for this class its called Receiver : public void get(People person) { if(null != person) { LOG.info("Person with ID " + person.getId() + " received"); processor.process(person); }else{ LOG.info("Person not received abort!"); } } Here is the test : @Test public void testReceivePerson(){ context.checking(new Expectations() {{ receiver.get(person); atLeast(1).of(person).getId(); will(returnValue(String.class)); }}); } Note: receiver is the instance of Receiver class(real not mock), processor is the instance of Processor class(real not mock) which processes the person(mock object of People class). GetId is a String not int method that is not mistake. Test fails : unexpected invocation of person.getId() I'm using jMock any help would be appreciated. As I understood when I call this get method to execute it properly I need to mock person.getId() , and I've been sniping around in circles for a while now any help would be appreciated.

• Cannot Translate to SQL using Select(x => Func(x))

  - by Dan

  I'm slowly learning the ins and outs of LINQtoSQL, but this is confusing me. Here is the statement I have: IQueryable<IEvent> events = (from e in db.getEvents() select e).Select(x => SelectEvent(x, null)); What the SelectEvent does can be explained in this answer here. I am not using the .toList() function as I don't want potentially thousands of records brought into memory. public IEvent SelectEvent(SqlServer.Event ev, EventType? type) { // Create an object which implements IEvent // I don't have the code in front of me, so forgive the lack of code } My question is really for the Select() method. I get the "Cannot translate to SQL" error and the Select() is listed in the error message. Clueless on this one :-/.

• Blackberry RepeatRule

  - by Vinay

  Hi All, I am very new to Blackberry development. I am trying to access the Blackberry Events (Calender) list. Currently, I am able to read the basic information from the event list. I am stuck in getting the info regarding the RepeatRule. My code is as below: EventList eventList = (EventList)PIM.getInstance().openPIMList(PIM.EVENT_LIST, PIM.READ_ONLY); Enumeration e = eventList.items(); while (e.hasMoreElements()) { Event event = (Event)e.nextElement(); RepeatRule rRule = event.getRepeat() ; if (rRule != null) { fieldIds = rRule.getFields() ; // Here I get the values as { 0,128,64,2}. How do I decode this information? } } Can any one help in decoding this information. Any kind of links, examples or pointers would be of great help. Thanks and regards, Vinay

• Nested sql queries in rails when :has_and_belongst_to_many

  - by Godisemo

  Hello, In my application I the next task that has not already been done by a user. I have Three models, A Book that has many Tasks and then I have a User that has has and belongs to many tasks. The table tasks_users table contains all completed tasks so I need to write a complex query to find the next task to perform. I have came up with two solutions in pure SQL that works, but I cant translate them to rails, thats what I need help with SELECT * FROM `tasks` WHERE `tasks`.`book_id` = @book_id AND `tasks`.`id` NOT IN ( SELECT `tasks_users`.`task_id` FROM `tasks_users` WHERE `tasks_users`.`user_id` = @user_id) ORDER BY `task`.`date` ASC LIMIT 1; and equally without nested select SELECT * FROM tasks LEFT JOIN tasks_users ON tasks_users.tasks_id = task.id AND tasks_users.user_id = @user_id WHERE tasks_users.task_id IS NULL AND tasks.book_id = @book_id LIMIT 1; This is what I Have done in rails with the MetaWhere plugin book.tasks.joins(:users.outer).where(:users => {:id => nil}) but I cant figure out how to get the current user there too, Thanks for any help!

• Using WINAPI ReadConsole

  - by Jim Fell

  I am trying to use the WINAPI ReadConsole() to wait for any keypress at the end of my Win32 console application. CONSOLE_READCONSOLE_CONTROL tControl; char pStr[65536]; DWORD dwBufLen = 1; DWORD dwCtl; tControl_c.nLength = sizeof( CONSOLE_READCONSOLE_CONTROL ); tControl_c.nInitialChars = 0; tControl_c.dwControlKeyState = 0; tControl_c.dwCtrlWakeupMask = NULL; pBuf[0] = 0x00; do { ReadConsole( hConsole_c, pStr, (*pBufLen) * sizeof(TCHAR), pBufLen, &tControl ); } while ( pStr[0] == 0x00 ); The code executes without throwing an exception. However, when the ReadConsole() function executes the error code ERROR_INVALID_HANDLE (0x06) is flagged. I have verified hConsole_c to be a valid handle. Does anyone have any insight as to what I am doing wrongly? I am using Visual C++ 2008 Express Edition. Thanks.

• asp.net mvc default model binding problem

  - by csetzkorn

  I have some problems with ASP.NET MVC’s default model binder. The View contains HTML like this: <input name="SubDTO[0].Id" value="1" type="checkbox"> <input name="SubDTO[1].Id" value="2" type="checkbox"> This is my simplified ‘model’: public class SubDTO { public virtual string Id { get; set; } } public class DTO { public List<SubDTO> SubDTOs { get; set; } public DTO() { SubDTOs = new List< SubDTO>(); } } All this works fine if the user selects at least the first checkbox (SubDTO[0].Id). The controller ‘receives’ a nicely initialised/bound DTO. However, if the first check box is not selected but only, for example, SubDTO[1].Id the object SubDTOs is null. Can someone please explain this ‘strange’ behaviour and how to overcome it? Thanks. Best wishes, Christian

• Jenkins and Visual Studio Online integration authentication

  - by user3120361

  right now I am trying to Setup Continuouse Integration - Delivery for a basic WCF Service, which will be hosted on a Microsoft Azure VM. The Project is Version Controlled through Visual Studio Online. So I installed Jenkins (also on the Azure VM), TFS plugin etc. and started the first Test Build: As Server URL I used "[VSO Adress]/DefaultCollection" and for Login purposes my Microsoft Account (I can Access VSO with that). The Problem is, when I run the Build I get the following error: Started by user Developer Building in workspace C:\Program Files (x86)\Jenkins\jobs\test\workspace [workspace] $ "C:\Program Files (x86)\TEE-CLC-11.0.0.1306\TEE-CLC-11.0.0\tf.cmd" workspaces -format:brief -server:[VSO Adress]/DefaultCollection ****" An error occurred: Access denied connecting to TFS server [VSO Adress] (authenticating as har****@*******o.com) FATAL: Executable returned an unexpected result code [100] ERROR: null Finished: FAILURE So my question is, whether it is generally possible to connect Jenkins and VSO that way and if so, which login credentials are needed

• How to deal with extra space characters while Reading a CSV file?

  - by Ravi Dutt

  I am reading a CSV file with CSV Open Source API. as shown below: Java Code:--> CSVReader reader = new CSVReader(new FileReader(filePath),'\n'); String[] values; if((read=(reader.readNext()))!=null) { values = (read[0].split(" (?=([^\"]*\"[^\"]*\")*[^\"]*$)",-1)).length; } // code ends here When I read this CSV file line by line and split that line with delimiter. Then after spliting values each value I get contains extra space character after each character in String. Suppose value in file is like "ABC" and I got this after reading from CSV file reader as " A B C " . I used removeAll("\s+","") on each value even after it is not working. Thank You in Advance.

• Cancel a UIView animation?

  - by Phil Nash

  Is it possible to cancel a UIView animation while it is in progress? Or would I have to drop to the CA level? i.e. I've done something like this (maybe setting an end animation action too): [UIView beginAnimations:nil context:NULL]; [UIView setAnimationDuration:duration]; [UIView setAnimationCurve: UIViewAnimationCurveLinear]; // other animation properties // set view properties [UIView commitAnimations]; But before the animation completes and I get the animation ended event, I want to cancel it (cut it short). Is this possible? Googling around finds a few people asking the same question with no answers - and one or two people speculating that it can't be done.

• How do you refresh the contents of an R gWidget?

  - by Richie Cotton

  I'm creating a GUI in R using gWidgets (more specifically gWidgetstcltk). I'd like to know how to update the contents of selection-type widgets, such as gdroplist and gtable. I currently have a rather hackish method of deleting the widget and re-creating it. I'm sure there's a better way. This simple example displays all the variables in the global environment. library(gWidgets) library(gWidgetstcltk) create.widgets <- function() { grp <- ggroup(container = win) ddl <- gdroplist(ls(envir = globalenv()), container = grp) refresh <- gimage("refresh", dirname = "stock", container = grp, handler = function(h, ...) { if(exists("grp") && !is.null(grp)) { delete(win, grp) rm(grp) } grp <- create.widgets() } ) } win <- gwindow() grp <- create.widgets()

• How to keep an Hibernate's Session open until the page is rendered

  - by Neuquino

  I'm having the following problem: I'm using Oracle ADF for the view and controller of my app. With OpenSessionInViewFilter, I intercept the request and open an Hibernate's Session, and it is closed as soon as the bean's method finishes. What I need is to keep the Session opened until the page is rendered, because in my JSP y use the lazy attributes of the object i load from the DB. For example: When I enter index.jspx the IndexBean#main() is executed: public class IndexBean{ private DBObject myDBObject; public String main(){ this.myDBObject = this.myDAO.loadObjectFromDB(); return null; } } in index.jspx I have: ... <af:inputText value="#{myDBObject.lazyAttribute}" /> ... I'd like that the Hibernate's Session keeps open until the af:inputText is processed. Is this possible? How? Thanks in advance

• display a confirmation popup on button click based on condition

  - by Raaz

  I have a p:commandButton on click of which I need to add a few values to a list. In my managed bean, I'm validating the value that has to be added, and if it validates to false, I have to display a confirmation popup. This is my code - <p:commandButton id="add" value="Add" type="submit" action="#{bean.doAdd}" ajax="false" update=":List"/> And in the bean, on click of the "Add" button, public String doAdd() throws Exception { if(response != null) { if(keyList.contains(response)) { if(!responseList.contains(response)) { responseList.add(response); } } else { //Have to display confirmation popup. } response = ""; } return response; } I'm using jsf 2.0 and primefaces 3.0. Can someone please tell me how to display the popup from the bean?

• How to replace values in multi-valued ESE column?

  - by Soonts

  I have a multi-valued short ASCII text column in one of the tables in my ESE database, that holds the person's phone numbers. I have the new set of values, and I'd like to wipe the old values completely, and only use the new values. The JET_bitSetRevertToDefaultValue bit doesn't seem to work. While the MSDN documentation says "It causes the column to return the default column value on subsequent retrieve column operations. All existing column values are removed.", I found that it does nothing (no return value is returned). Or, is there an easy way to find out how many values does the column contain (this could be zero, e.g. when I'm doing an insertion, not update)? If it was, I could just run a loop from 'nValues' to 1, erasing the value by setting it to the null while providing the itagSequence value, to achieve what I want. I'm programming C#, and using the latest version of ManagedEsent library. Thanks in advance!

• In WPF using a ListView is there an elegant way to auto resize items?

  - by Justin

  I recently wrote, my first, WPF application that has a list of items that are polled from a web-serivce. The items are displayed/data-bound in a ListView via a GridView. A background thread periodically polls the web-serivce and updates the list. If, say, I had three items initially bound to the ListView that simply display a description and the three descriptions where something like: - ProjectA - ProjectB - ProjectC Later a new item is added with a description of 'AReallyReallyLongProjectName', I would end up with a list like: - ProjectA - ProjectB - ProjectC - AReallyR The GridViewColumn would not update it's width and would subsequently cut off any new items that extended the original width. I added this bit of code which forces the column to resize, but it just seems a little hacky. (Just seems weird to set a width just to set it back to nothing to force the resize) if(gridView != null) { foreach(var column in gridView.Columns) { if (double.IsNaN(column.Width) column.Width = column.ActualWidth; column.Width = double.NaN; } } Is there a better, more elegant solution, to accomplish this same thing?

• PostgreSQL: keep a certain number of records in a table

  - by Alexander Farber

  Hello, I have an SQL-table holding the last hands received by a player in card game. The hand is represented by an integer (32 bits == 32 cards): create table pref_hand ( id varchar(32) references pref_users, hand integer not NULL check (hand > 0), stamp timestamp default current_timestamp ); As the players are playing constantly and that data isn't important (just a gimmick to be displayed at player profile pages) and I don't want my database to grow too quickly, I'd like to keep only up to 10 records per player id. So I'm trying to declare this PL/PgSQL procedure: create or replace function pref_update_game(_id varchar, _hand integer) returns void as $BODY$ begin delete from pref_hand offset 10 where id=_id order by stamp; insert into pref_hand (id, hand) values (_id, _hand); end; $BODY$ language plpgsql; but unfortunately this fails with: ERROR: syntax error at or near "offset" because delete doesn't support offset. Does anybody please have a better idea here? Thank you! Alex
