  • Silverlight calling windows workflow foundation as a web service

    - by wissem
    hi, I'm trying to call a windows workflow foundation published as a web service from a Silverlight project. When I call it from a console application it works fine because I can add a web reference then I just make an instance of that webservice then I invoke the method I want. The problem is in the silverlight project cause i can just add a service reference so I find myself working with soap stuff that doesn't work at all, and here is the code: private void btnUpdate_Click(object sender, RoutedEventArgs e) { xxxxxxx.Workflow1_WebServiceSoapClient zer = new xxxxx.Workflow1_WebServiceSoapClient(); zer.demanderSubmitReportCompleted += new EventHandler<xxxxxxxxxxxxxxx.demanderSubmitReportCompletedEventArgs>(service2); zer.demanderSubmitReportAsync("zzz", 20000); } public void service2(object sender, xxxxx.demanderSubmitReportCompletedEventArgs e) { string a = e.Result; } plz help ,thanks

  • Validating call to web service against schema before sending request

    - by Cen
    I am calling a web service (written in Java) in my web app. I use the WSDL to generate proxy classes using the wsdl.exe command line tool. Everything is working fine. However, I have found out that the web service is not doing any data validation at all when they receive a request from my app. Hence, if I happen to send one minute piece of data that isn't exactly what they want, I receive a general fault error in return, with no specifics at all of what the incorrect (if any) piece of data is. So, before I make the request, I'd like to validate my request against the schema they have provided. Is this possible, and if so, how do I go about this? Thanks in advance

  • django modeling

    - by SledgehammerPL
    Concept: Drinks are made of components. E.g. 10ml of Vodka. In some receipt the component is very particular (10ml of Finlandia Vodka), some not (10 ml of ANY Vodka). I wonder how to model a component to solve this problem - on stock I have particular product, which can satisfy more requirements. The model for now is: class Receipt(models.Model): name = models.CharField(max_length=128) (...) components = models.ManyToManyField(Product, through='ReceiptComponent') def __unicode__(self): return self.name class ReceiptComponent(models.Model): product = models.ForeignKey(Product) receipt = models.ForeignKey(Receipt) quantity = models.FloatField(max_length=9) unit = models.ForeignKey(Unit) class Admin: pass def __unicode__(self): return unicode(self.quantity!=0 and self.quantity or '') + ' ' + unicode(self.unit) + ' ' + self.product.genitive class Product(models.Model): name = models.CharField(max_length = 128) (...) class Admin: pass def __unicode__(self): return self.name class Stock(Store): products = models.ManyToManyField(Product) class Admin: pass def __unicode__(self): return self.name I think about making some table which joins real product (on stock) with abstract product (receiptcomponent). But maybe there's easy solution?

  • Recursive CTE with alternating tables

    - by SOfanatic
    I've created a SQL fiddle here. Basically, I have 3 tables BaseTable, Files, and a LinkingTable. The Files table has 3 columns: PK, BaseTableId, RecursiveId (ChildId). What I want to do is find all the children given a BaseTableId (i.e., ParentId). The tricky part is that the way the children are found works like this: Take ParentId 1 and use that to look up a FileId in the Files table, then use that FileId to look for a ChildId in the LinkingTable, if that record exists then use the RecursiveId in the LinkingTable to look for the next FileId in the Files table and so on. This is my CTE so far: with CTE as ( select lt.FileId, lt.RecursiveId, 0 as [level], bt.BaseTableId from BaseTable bt join Files f on bt.BaseTableId = f.BaseTableId join LinkingTable lt on f.FileId = lt.FileId where bt.BaseTableId = @Id UNION ALL select rlt.FileId, rlt.RecursiveId, [level] + 1 as [level], CTE.BaseTableId from CTE --??? and this is where I get lost ... ) A correct output for BaseTableId = 1, should be: FileId|RecursiveId|level|BaseTableId 1 1 0 1 3 2 1 1 4 3 2 1

  • Passing an object as a parameter to a windows service

    - by user220723
    Is there some way to pass an object to a windows service? I know the method myServiceController.Star(string[] arg) but i need to pass a more complex object than a string array. Actually, i don't need the object to be passed as a parameter, what i really needs is that the service can use an object created in a windows forms application. I've tried using System.Web.Script.Serialization.JavaScriptSerializer.Serialize method to convert the object into a Json but i couldn't because the object contains a circular reference. I also tried using pointers, but i couldn't becouse it is a managed type object. Any idea what can i do?

  • Google Map Web Service working on local but not online

    - by Julien
    Hi all, I have a problem with a Javascript request to the Google Map Api Web Service : if I have the HTML file on my computer it works, but it doesn't work online.

  • Master data validation in service layer

    - by rakesh-nitj
    User enters the data in the forms by choosing values from the master data drop downs in web layer. Data is populated in the dropdowns based on some logic from the master data tables and we know for sure that its a valid master data as far as web layer is concern. Now my question is, should be check the validity of the master data in service layer again because we want to use service layer for mulitple interfaces (Web User Interface, Web Services, Unit Test Cases etc.) or we should validate the master data in respective interfaces only.

  • What have you learned from your students?

    - by Helper Method
    It is said that a true master learns from his students. Since I'm tutoring at university, from time to time a question or a comment from the students I'm working with made me to see something from a different perspective, you get deeper insights, etc. So, what have you learned from your students/junior developers/... ?

  • C++ - Need to learn some basics in a short while

    - by Rubys
    For reasons I will spare you, I have two weeks to learn some C++. I can learn alone just fine, but I need a good source. I don't think I have time to go through an entire book, and so I need some cliff notes, or possibly specific chapters/specialized resources I need to look up. I know my Asm/C/C# well, and so anything inherited from C, or any OOP is not needed. What I do need is some sources on the following subjects(I have a page that specifies what is needed, this is basically it, but I trimmed what I know): new/delete in C++ (as opposed to C#). Overloading cin/cout. Constructor, Destructor and MIL. Embedded Objects. References. Templates. If you feel some basic C++ concept that is not shared with C/C# is not included on this list, feel free to enter those as well. But the above subjects are the ones I'm supposed to roughly know in two week's time. Any help would be appreciated, thanks.

  • Just 2 free months to learn or improve my skills

    - by microspino
    On the 30 of June I will leave my every day work to start as freelance developer. I'd like to set a period of 2 months apart to improve my dev skills. At work I code in C# and during my spare time I enjoyed building Ruby on Rails web applications and creating some Arduino prototypes. I'm something more than junior but I don't feel really a senior developer because I never had a big corporate project built and designed by me with help of other juniors (although I don't think this is really a good definiton of a "senior", It helps describing my feelings). Using a scale from 0 (ignorant) to 10 (proficient like a "samurai") the list below describes my skills that I would like to improve with just 2 months. I've already bought some nice and updated books on all the subjects hereunder: The order doesn't matter C = 1 C# & .Net = 6 Arduino & Processing = 2 Ruby = 5 Rails = 5 HTML/XHTML/CSS = 9 Javascript = 6 Objective-C/iPhone dev = 2 Python = 4 Django = 4 Desing Patterns = 3 Algorythms = 3 Git = 5 I haven't included SQL or Databases in general nor Networking because I spent 10 years working in the past with them and I feel pretty solid for now. As an aside, I've made up some interest in Redis, Node.js, HTML5 reading about them on the web. After two months, since I have to pay my bills, I could go searching for some new job. If learning and developing were really good maybe I could also invest on something I gave birth during them. Can You give me some piece of advice on which you think It's better to improve or develop a learning project on (something like a "summer of code" thing)? The all point Is to see my weaknesses and work on them.

  • Drupal OAuth Service Module

    - by user470714
    I am trying to do some research into potentially setting up an existing Drupal site with user accounts/login page to also be an OAuth service provider, basically authenticating users to make calls with a web service. I am looking for a Drupal module which will give this functionality. Most of what I run into are OAuth consumer modules, which is not what I want in this case. I've found a few modules which I think might do this for me, but the module descriptions are generally pretty vague and don't have much of a user base which doesn't inspire much confidence. Has anyone else done this before? What are the best modules available for doing this?

  • Writing code to be a better programmer

    - by wtfsven
    A while back I heard on a podcast about a site listing "10 applications to write that will make you a better programmer." I'm desperate to find where this is, or at the very least a decent list from someone here. The thing is, I've been writing code for about 8 years now, and it's my passion. Very few things make me happier than getting lost in some C# or Python. But I've spent the last 2 years in a job that doesn't allow me much time to do what I love. Now everyone knows that the best way to keep your coding sword sharp is to use it, and I've noticed recently that mine is getting dull. Does anyone have any suggestions on some simple programs to help flex my coding muscle? I'm one of those odd few who actually likes writing CRUD applications, so stuff like that would be nice, too.

  • How to keep up the interest in job?

    - by stranger
    Hi, I have been working as Software Developer for 6+ yrs. And I have worked from start ups to big companies. I always feel some elements missing in me and those are interest, passion etc. In short, I don't feel motivated while coming to work. This makes me think how my work-life balance will look like once I reach at more responsible positions. I don't want to change my field and I feel blessed as well but I think I am not working passionately for my learning, future growth, improvement, skills etc. Any pointers will be highly appreciated. Thx

  • Could this be considered a well-written PHP5 class?

    - by Ben Dauphinee
    I have been learning OOP principals on my own for a while, and taken a few cracks at writing classes. What I really need to know now is if I am actually using what I have learned correctly, or if I could improve as far as OOP is concerned. I have chopped a massive portion of code out of a class that I have been working on for a while now, and pasted it here. To all you skilled and knowledgeable programmers here I ask: Am I doing it wrong? class acl extends genericAPI{ // -- Copied from genericAPI class protected final function sanityCheck($what, $check, $vars){ switch($check){ case 'set': if(isset($vars[$what])){return(1);}else{return(0);} break; } } // --------------------------------- protected $db = null; protected $dataQuery = null; public function __construct(Zend_Db_Adapter_Abstract $db, $config = array()){ $this->db = $db; if(!empty($config)){$this->config = $config;} } protected function _buildQuery($selectType = null, $vars = array()){ // Removed switches for simplicity sake $this->dataQuery = $this->db->select( )->from( $this->config['table_users'], array('tf' => '(CASE WHEN count(*) > 0 THEN 1 ELSE 0 END)') )->where( $this->config['uidcol'] . ' = ?', $vars['uid'] ); } protected function _sanityRun_acl($sanitycheck, &$vars){ switch($sanitycheck){ case 'uid_set': if(!$this->sanityCheck('uid', 'set', $vars)){ throw new Exception(ERR_ACL_NOUID); } $vars['uid'] = settype($vars['uid'], 'integer'); break; } } private function user($action = null, $vars = array()){ switch($action){ case 'exists': $this->_sanityRun_acl('uid_set', $vars); $this->_buildQuery('user_exists_idcheck', $vars); return($this->db->fetchOne($this->dataQuery->__toString())); break; } } public function user_exists($uid){ return($this->user('exists', array('uid' => $uid))); } } $return = $acl_test->user_exists(1);

  • Design RESTful service with multiple ids

    - by Dustin Digmann
    I am designing a RESTful service. It is to list a set of data. The main problem is that the set does not have a reasonable, single identifier. Nor can the specific set be easily calculated within the knowledge of the system. As a result, it does not seem possible to have a GET /items/{identifier} service. I do have the id of each element being requested. My main issue is that it does not seem RESTful to list the ids in the URI (eg GET items/{id1},{id2},...,{idn} ). Right? I could see DELETE having a similar use case - remove multiple items in one request cycle. How would such a use case be satisfied while staying within the REST realm? Is that possible?

  • Calling ASP.NET web service function via GET method with jQuery

    - by the_V
    Hi, I'm trying to call web service function via GET method using jQuery, but having a problem. This is a web service code: [WebService(Namespace = "http://something.com/samples")] [ScriptService] [WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)] public class TestWebService : System.Web.Services.WebService { [WebMethod] public string Test2() { string result = null; try { result = "{'result':'success', 'datetime':'" + DateTime.Now.ToString() + "'"; } catch (Exception ex) { result = "Something wrong happened"; } return result; } } That's the way I call the function: $.ajax({ type: "GET", url: "http://localhost/testwebsite/TestWebService.asmx/Test2", data: "{}", contentType: "application/json", dataType: "json", error: function (xhr, status, error) { alert(xhr.responseText); }, success: function (msg) { alert('Call was successful!'); } }); Method is called successfully, but result string gets covered by XML tags, like this: <string> {'result':'success', 'datetime':'4/26/2010 12:11:18 PM' </string> And I get an error because of this (error handler is called). Does anybody know what can be done about this?

  • How can a language be interpreted by itself (like Rubinius)?

    - by japancheese
    I've been programming in Ruby for a while now with just the standard MRI implementation of Ruby, but I've always been curious about the other implementations I hear so much about. I was reading about Rubinius the other day, a Ruby interpreter written in Ruby. I tried looking it up in various places, but I was having a hard time figuring out exactly how something like this works. I've never had much experience in compilers or language writing but I'm really interested to figure it out. How exactly can a language be interpreted by itself? Is there a basic step in compiling that I don't understand where this makes sense? Can someone explain this to me like I'm an idiot (because that wouldn't be too far off base anyways)

  • How to Design Programs: An Introduction to Programming and Computing -- teacher guide access

    - by user295683
    Hello -- I'm a biologist switching careers, and trying to learn programming as a result. I stumbled upon the aforementioned book on Amazon, which jived with my liberal arts background. Despite my great satisfaction with the didactic approach, I was frustrated to see that the answers to the exercises are restricted to teachers only. As I am pursuing this endeavor on my own, this restriction dramatically cripples the value of this book. My request to the author's website for access to the answers has not been answered, and I would desperately like to continue with this book. Anyone have any experience dealing with the book's website, or at the very least a torrent of the answers? Otherwise, I suspect I will be relegated to using JavaScript for everything! Thanks!

  • Beginner questions regarding Python classes.

    - by Andy
    Hi. I am new to Python so please don't flame me if I ask something too noobish :) 1. Consider I have a class: class Test: def __init__(self, x, y): self.x = x self.y = y def wow(): print 5 * 5 Now I try to create an object of the class: x = Test(3, 4) This works as expected. However, when I try to call the method wow(), it returns an error, which is fixed by changing wow() to: def wow(self) Why do I need to include self and if I don't, what does the method mean?2. In the definition of __init__: def __init__(self, x, y): self.x = x self.y = y Why do I need to declare x and y, when I can do this: def __init__(self): self.x = x self.y = y I hope I am being clear... Thanks for your time.
