• Eclipse Code Templates with Cobol

  - by Bruno Brant

  People, My team is just beginning to learn how to use COBOL on Eclipse (as part of the Rational Developer for System Z package) and one of our most desired features are code templates or code snippets. What we'd like to have is a code completion based on snippets just like we have on Java. For example, when I type try and hit ctrl-space Eclipse shows me a list of completion options, where one of those is create a try/catch block. Well, in COBOL one could leverage this when creating, for example, embedded SQL blocks, like EXEC SQL SELECT field, field, field, FROM table WHERE field = value, field = value END-EXEC. However, for some reason, it seems that Eclipse treats COBOL a little differently (no wonder why) from other languages. As such, when looking for the code templates in the preferences menu for COBOL, its appearance is very different from the Java one. The question is: how does one uses Eclipse's code templates with COBOL?

• Symfony2 trans_default_domain is not working

  - by user1069843

  At the end of http://symfony.com/doc/current/book/translation.html#twig-templates I read about {% trans_default_domain "app" %} to set a translation domain for a whole template. But for me it does not work. Calling app/console translation:extract de --dir=src/ --output-dir=app/Resources/translations --output-format=xliff --keep Just puts all messages in the messages.de.xliff file. But if I set the domain manually for a given label like {{ label.name|trans({}, 'app') }} And execute the same extract command as above, then I get a new file app.de.xliff Is there anything more to do when using trans_default_domain?

• Importing Thawte trial certificates into a Java keystore

  - by lindelof

  Hello, I'm trying to configure a Tomcat server with SSL. I've generated a keypair thus: $ keytool -genkeypair -alias tomcat -keyalg RSA -keystore keys Next I generate a certificate signing request: $ keytool -certreq -keyalg RSA -alias tomcat -keystore keys -file tomcat.csr Then I copy-paste the contents of tomcat.csr into a form on Thawte's website, asking for a trial SSL certificate. In return I get two certificates delimited with -----BEGIN ... -----END, that I save under tomcat.crt and thawte.crt. (Thawte calls the second certificate a 'Thawte Test CA Root' certificate). When I try to import either of them it fails: $ keytool -importcert -alias tomcat -file tomcat.crt -keystore keys Enter keystore password: keytool error: java.lang.Exception: Failed to establish chain from reply $ keytool -importcert -alias thawte -file thawtetest.crt -keystore keys Enter keystore password: keytool error: java.lang.Exception: Input not an X.509 certificate Adding the -trustcacerts option to either of these commands doesn't change anything either. Any idea what I am doing wrong here?

• jQuery Datepicker - Programatically Limit Second Datepicker

  - by Dodinas

  Hello all, I've recently been using the following piece of code to limit my 2nd Date picker (end date) so that it does not precede the date of the 1st Date picker. $("#datepicker").datepicker({ minDate: +5, maxDate: '+1M +10D', onSelect: function(dateText, inst){ var the_date = dateText; $("#datepicker2").datepicker('option', 'minDate', the_date); } }); $("#datepicker2").datepicker({ maxDate: '+1M +10D', onSelect: function(dateText, inst){ } }); However, lately, I wanted to format my datepickers using: dateFormat: 'yy-mm-dd' But now, the 2nd datepicker actually allows the user to pick a date 1 day before. For example, if the user picks the 1st date: 2010-04-03, when the 2nd Datepicker pops up, they are able to pick 2010-04-02 (1 day before their first selected date). I do not want the user to be able to pick a date that was before their first selected day. Any ideas why this isn't working after I added in the "dateFormat"?

• MYSQL stored function - create function (function definition) problem using FORMAT

  - by Jason Fonseca

  Hi all, I keep receiving an error with the following code. I am trying to make a function that will format a field (content=0.0032) into a varchar/percent (content=0.32%). At the moment i'm just trying to get format to work, and it throws up an error "Error Code : 1064 You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'len);" The function definition for "Format" is "Format(X,d)" where x is the number and d is the number of decimal places to round too. It then should output a string ###,###,###.## etc. My code is as follows: DROP FUNCTION IF EXISTS percent; DELIMITER $$ CREATE /*[DEFINER = { user | CURRENT_USER }]*/ FUNCTION `auau7859_aba`.`percent`(num DOUBLE, len INT) RETURNS VARCHAR(10) DETERMINISTIC BEGIN RETURN FORMAT(num,len); END$$ DELIMITER ; Save me...Luke

• Any screen capture software that captures webcam, microphone inputs too ?

  - by mohanr

  I am going to conduct a user study. Apart from capturing the screen while the user is interacting with the system, I also want to capture the video/audio of the user. Is there any software that in addition to capturing the screen also overlays it with the webcam/microphone inputs. The goal is to capture the complete experience of the user: key/mouse interactions with the system along with their facial/vocal responses. I know that I can maybe run a screen-capture software and also run a software for capturing webcam audio/video alongside and try to sync/overlay both these streams with timestamps. But I am going to be dealing with probably several hundred hours of data. So I am looking for a tool that can streamline the process for me amap and help me keep my sanity at end of the process. Thanks,

• Serialize struct with pointers to NSData

  - by leolobato

  Hey guys, I need to add some kind of archiving functionality to a Objective-C Trie implementation (NDTrie on github), but I have very little experience with C and it's data structures. struct trieNode { NSUInteger key; NSUInteger count, size; id object; __strong struct trieNode ** children; __strong struct trieNode * parent; }; @interface NDTrie (Private) - (struct trieNode*)root; @end What I need is to create an NSData with the tree structure from that root - or serialize/deserialize the whole tree some other way (conforming to NSCoding?), but I have no clue how to work with NSData and a C struct containing pointers. Performance on deserializing the resulting object would be crucial, as this is an iPhone project and I will need to load it in the background every time the app starts. What would be the best way to achieve this? Thanks!

• T-sql Common expression query as subquery

  - by ase69s

  I have the following query: WITH Orders(Id) AS ( SELECT DISTINCT anfrageid FROM MPHotlineAnfrageAnhang ) SELECT Id, ( SELECT CONVERT(VARCHAR(255),anfragetext) + ' | ' FROM MPHotlineAnfrageAnhang WHERE anfrageid = Id ORDER BY anfrageid, erstelltam FOR XML PATH('') ) AS Descriptions FROM Orders Its concatenates varchar values of diferents rows grouped by an id. But now i want to include it as a subquery and it gives some errors i cant solve. Simplified example of use: select descriptions from ( WITH Orders(Id) AS ( SELECT DISTINCT anfrageid FROM MPHotlineAnfrageAnhang ) SELECT Id, ( SELECT CONVERT(VARCHAR(255),anfragetext) + ' | ' FROM MPHotlineAnfrageAnhang WHERE anfrageid = Id ORDER BY anfrageid, erstelltam FOR XML PATH('') ) AS Descriptions FROM Orders ) as tx where id=100012 Errors (Aproximate translation from spanish): -Incorrect sintaxis near 'WITH'. -Incorrect sintaxis near 'WITH'. If the instruction is a common table expression or a xmlnamespaces clause, the previous instruction must end with semicolon. -Incorrect sintaxis near ')'. What im doing wrong?

• passing json from servlet to dojo

  - by Moev4

  I am currently trying to pass a generated JSON string to dojo for parsing and am having some issues. The servlet simply writes it as a string as so: response.getWriter().append("{ \"data\": {"); response.getWriter().append("\"type\": \"facing\","); response.getWriter().append("\"score\": " + "\"" + score + "\","); response.getWriter().append("\"count\":" + "\"" + count + "\"" ); response.getWriter().append("}}"); which prints as: {"data":{"type":"facing","score":"10","count":"24"}} And the parsing on the dojo end looks as so: dojo.xhrPost({ url: url, handleAs: "json", load: function(data) { alert(data); /* Parse Not working */ alert(data.data[0].type); }, error: function(error) { alert("No dice") } }); The main issue is the data.data[0].type is returning nothing but when i print this out as text the json seems to be correctly formatted. Any help with this would be appreciated.

• How do I create sub-applications in Django?

  - by jamida

  I'm a Django newbie, but fairly experienced at programming. I have a set of related applications that I'd like to group into a sub-application but can not figure out how to get manage.py to do this for me. Ideally I'll end up with a structure like: project/ app/ subapp1/ subapp2/ I've tried: manage.py startapp app.subapp1 manage.py startapp app/subapp1 but this tells me that / and . are invalid characters for app names I've tried changing into the app directory and running ../manage.py subapp1 but that makes supapp1 at the top level. NOTE, I'm not trying to directly make a stand-alone application. I'm trying to do all this from within a project.

• Sharepoint SSO bulk creation of user accounts

  - by user292884

  Hopefully someone can help... I need to provide client with a solution to allow bulk creation of user accounts into SharePoint SSO. The client wants to provide an excel spreadsheet with accounts, usernames and passwords and have that created in the SSO database. I've been told its possible but I can't see how and google is failing me. I've been told its "some custom development and the SharePoint object model". As far as I can see all of the credentials stuff in the Microsoft.SharePoint.Portal.SingleSignon namespace is very much read only. I have a solution which is to get them to save the spreadsheet as a CSV file and to use jmeter to squirt the data in through the front end. I don't think that's really an acceptable solution though. Anyone got any clues? Or can anyone say definitively this can't be done? Thanks in advance...

• SQL Server CE - Internal error: Cannot open the shared memory region

  - by blu

  I have a SQL Server CE database that works fine in dev, but when installed on the client has an issue. The SQL Server CE 3.5 dependencies are copied as part of the deployment. The target machine is a clean Windows 7 32-bit Ultimate image. The message for the exception in the event log is: Internal error: Cannot open the shared memory region. It looks like this is SSCE_M_CANTOPENSHAREDMEMORY and the site says there isn't a connection string value to change this and that these issues are typically not resolvable by the end developers. Has anyone run into this, and if so were you able to resolve this issue?

• Mercurial branching a branch doesn't display right in hg serve or hg view

  - by Mystic

  I've been doing some development on a branch and realized that before it could be complete something else need to be done first. I decided that I would branch my current branch and do the requiste changes in that branch then merge them back together and then merge my working branch into default. Basically I expected this: | | + requiste work branch commit. | |/ | + working branch commit |/ +Default branch commit and in the end what I expect to do is this: + Merge into defualt |\ | + Merge requisite work into working branch | | \ | | + requiste work branch commit. | |/ | + working branch commit |/ +Default branch commit What I'm getting in both hg view and hg serve is this: | + requiste work branch commit. | | | + working branch commit |/ +Default branch commit However, when I look at the commit log "requiste work branch commit" is marked as a part of a different branch. Am I doing something wrong? Is this a bug in hg view and hg serve? Anyone experienced this before?

• External SWF to External SWF Timeline Communication, Flash, AS2

  - by jecca411

  Flash CS4, AS2 I have made an interactive tour. It can be seen here: http://www.92YTribeca.org/Tour click on the bottom image Each of the 4 sections are external swf and loaded on level 1. I want a button on one swf (floorplan) to load another swf (facility rentals) AND pinpoint a specific frame on the swf's timeline. I have tried many different ways, all end up loading the swf at the first frame and ignore the rest of the code talking about the timeline. I know I could split this swf up into more external swfs and get the result I want, but I would rather use code if I can. Is what I want to do possible? If so, how do I write the code? Thanks!

• Basics of automated tests?

  - by Muhammad Yasir

  Hi, Till now I've been testing my web (usually written in PHP) as well as desktop applications (normally Java or C#) manually. Now I read somewhere on the net about automated tests. I tried searching to know about it in details but almost all searches end up at things like PHPUnit. Could someone please put some light on the theory behind automated tests? How a software can be tested automatically? Any limitations etc? Or may be you can tell me a place where I can read about this. Regards

• CodeIgniter & Datamapper as frontend, Django Admin as backend, database tables inconsistent

  - by Rasiel

  I created a database for a site i'm doing using Django as the admin backend. However because the server where the site is hosted on, won't be able to support Python, I find myself needing to do the front end in PHP and as such i've decided to use CodeIgniter along with Datamapper to map the models/relationship. However DataMapper requires the tables to be in a specific format for it to work, and Django maps its tables differently, using the App name as the prefix in the table. I've tried using the prefix & join_prefix vars in datamapper but still doesn't map them correctly. Has anyone used a combination of this? and if so how have the fixed the issue of db table names being inconsistent? Is there anything out there that i can use to make them work together?

• WM_CONCAT with DISTINCT Clause - Compiled Package versus Stand-Alone Query Issue

  - by Reimius

  I was writing some program that uses the WM_CONCAT function. When I run this query: SELECT WM_CONCAT(DISTINCT employee_id) FROM employee WHERE ROWNUM < 20; It works fine. When I try to compile the relatively same query in a package function or procedure, it produces this error: PL/SQL: ORA-30482: DISTINCT option not allowed for this function FUNCTION fetch_raw_data_by_range RETURN VARCHAR2 IS v_some_string VARCHAR2(32000); BEGIN SELECT WM_CONCAT(DISTINCT employee_id) INTO v_some_string FROM employee WHERE ROWNUM < 20; RETURN v_some_string; END; I realize WM_CONCAT is not officially supported, but can someone explain why it would work as a stand alone query with DISTINCT, but not compile in a package?

• Text to MP3 using System.Speech.Synthesis.SpeechSynthesizer

  - by Rob

  I am trying to get a text-to-speech to save to an MP3. Currently I have the System.Speech.Synthesis speaking to a WAV file nicely. With New System.Speech.Synthesis.SpeechSynthesizer '.SetOutputToWaveFile(pOutputPath) This works fine .SetOutputToWaveStream(<<Problem bit>>) .Speak(pTextToSpeak) .SetOutputToNull() .Dispose() End With Now the first line commented out produces a WAV file which is nice. Currently I am trying to replace that with an MP3 output stream and not having much success. I have tried the Yeti.MMedia converter but either it isn't going to work or I haven't got it to work successfully. I have to admit here I don't know much about encodings, speeds etc. So the question I have is, does anyone know of a nice way I can say something like the following: .SetOutputToWaveStream(New MP3WriteStream(pOutputPath)) and have the SpeechSynthesizer write to the WAV which then gets converted to the MP3 and ends up on the HDD.

• How is the presentation layer of a CALayer generated?

  - by KJ

  Hi, I'm having difficulties animating my custom layer property using Core Anmiation. My question is how the presentation of a CALayer is generated. Here is what I have now: @interface MyLayer : CALayer { NSMutableDictionary* customProperties; } @property (nonatomic, copy) NSMutableDictionary* customProperties; @end And when I try to animate the key path "customProperties.roll" using CABasicAnimation and addAnimation:forKey:, it seems that the customProperties variable doesn't get copied from the model layer to the presentation layer, and the customProperties of the presentation layer appears to be nil, failing to update the value for the key "roll". Is there a way to animate values in a dictionary correctly? What is the exact relationship between a model layer and a presentation layer while being animated? Thanks!
