  • Accessing NHibernate Repository using ASP.NET Ajax WebMethod

    - by LooDaFunk
    Hi there! on my page I have a save button that gets the values from the form and then saves it in the database using NHibernate. This works using ASP.net postback buttons. I have now added an Ajax WebMethod to make things sleek and quicker. Howver, when trying to access the data in the repository it doesn't seem to get it. I am passing in the correct values, and everything looks the same as when you are using the postback but no Joy! I should point out here that I'm a newbie with NHibernate and I'm working with someone elses code. Here's the code: the main problem is this line: Solution.Entities.Hierarchy.Tag tag = tagRep.Get(tagId); The tagID is fine, but when it does the get no exception is raised it just comes out the method and goes back to the page???? http://pastebin.com/cBTp9pnC Anyone have any ideas? Merry Christmas!

  • Mimic an HTTPRequest and HTTPResponse object in Java

    - by Ankur
    How do I mimic an HTTPServletRequest and HTTPServletResponse object. The reason is I want to test the behaviour of some servlets. I know JUnit probably provides this functionality but I don't know how to use it (I will learn soon) and need to do this reasonably quickly. HTTPServletRequest and HTTPServletResponse are both interfaces so they can't be instantiated. There is a HttpServletRequestWrapper which implements HttpServletRequest but it doesn't seem to have any setParameter() type methods and HttpServletResponse doesn't seem to have any implementing classes at all. How can I test my code by passing a suitable HttpServletRequest object and then checking that the received HttpServletResponse object matches what I expect?

  • Is there a methode to linarize a Document?

    - by M.R.
    A webservice response with a message which is not linarized. This produces a problem, when trying to access a (as an example) the root element with getSOAPBody().getFirstChlid(). In a linarized document this call would return the first element inside the the body. If the message is not properly formated, you may get the the line break between the soap body and the first element. The problem should be easy to solve with a recursive method, but I was wondering, if there is a method for it? Like normalize etc. Edit: XML Response: ... XMLSchema-instance"><soapenv:Body> <wst:RequestSecurityTokenResponse xmlns:wst="http://schemas.xmlsoap.org/ws/200/02/trust">... JAVA CODE: final DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance(); factory.setNamespaceAware(true); DocumentBuilder db = factory.newDocumentBuilder(); Document result = db.newDocument(); //messResult is the response result.appendChild(result.importNode(messResult.getSOAPBody().getFirstChild(),true)); Error Log: HIERARCHY_REQUEST_ERR: An attempt was made to insert a node where it is not permitted.

  • Perl, treat string as binary byte array

    - by Mike
    In Perl, is it appropriate to use a string as a byte array containing 8-bit data? All the documentation I can find on this subject focuses on 7-bit strings. For instance, if I read some data from a binary file into $data my $data; open FILE, "<", $filepath; binmode FILE; read FILE $data 1024; and I want to get the first byte out, is substr($data,1,1) appropriate? (again, assuming it is 8-bit data) I come from a mostly C background, and I am used to passing a char pointer to a read() function. My problem might be that I don't understand what the underlying representation of a string is in Perl.

  • Video Streaming

    - by Josephe
    First I need to state that I am not the developer so I will state the issue in business terms but please respond with a technical solution as I will be passing on your posts to the developer. We are building a web based application in SilverLight and WPF that consists of communication between a customer service rep and a customer. The application will inlcude a webcam that will provide the customer with the ability to see the customer service rep and the rep will also be able to see an image of themselves but will not be able to see the customer. Similar functionality to a live web chat with video component. There could potentially be bandwidth issues and we do not want the customer to have to download anything. Any recommendations on how to do this?

  • How to generate a good random seed to pass to srand()?

    - by zr
    Hi, I am writing a C++ program which needs to create a temporary file for its internal usage. I would like to allow concurrent executions of the program by running multiple proccesses, so the temporary file name needs to be randomized, that way each spawned process will generate a unique temporary file name for its own use. I am using rand() to generate random characters for part of the file name, so i need to initialize the random number generator's seed using srand(). What options are there for passing a good argument to srand() such that two processes will not be initialized with the same seed value? My code needs to work both on Windows and pn Linux TIA.

  • parse xml with elementtree, custom sorting

    - by microspace
    I want to parse xml file in utf-8 and sort it by some field. Soring is made by custom alphabet (s1 from sourcecode). History of question is here: sorting of list containing utf-8 charachters. I've found how to sort xml here. Sorting work correctly, the problem is with elementtree, I must admit that it doesn't work on python3 Here is source code: #!/usr/bin/env python # -*- coding: utf-8 -*- #import xml.etree.ElementTree as ET # Python 2.5 import elementtree.ElementTree as ET s1='aáàAâÂbBcCçÇdDeéEfFgGgGhHiIîÎíiiIjJkKlLmMnNóoOöÖpPqQrRsSsStTuUûúÛüÜvVwWxXyYzZ' s2='11111122334455666aabbccddeeeeeeffgghhiijjkklllllmmnnooppqqrrsssssttuuvvwwxxyy' trans = str.maketrans(s1, s2) def unikey(seq): return seq[0].translate(trans) tree = ET.parse("tosort.xml") container = tree.find("entries") data = [] for elem in container: keyd = elem.findtext("k") data.append((keyd, elem)) print (data) data.sort(key=unikey) print (data) container[:] = [item[-1] for item in data] tree.write("sorted.xml", encoding="utf-8") Here are instructions to import elementtree module.

  • Access report not showing data

    - by Brian Smith
    I have two queries that I am using to generate a report from, the problem is when I run the report, three fields do not show any data at all for some reason. Query 1: SELECT ClientSummary.Field3 AS PM, ClientSummary.[Client Nickname 2] AS [Project #], ClientSummary.[Client Nickname 1] AS Customer, ClientSummary.[In Reference To] AS [Job Name], ClientSummary.Field10 AS Contract, (select sum([Billable Slip Value]) from Util_bydate as U1 where U1.[Client Nickname 2] = ClientSummary.[Client Nickname 2]) AS [This Week], (select sum([Billable Slip Value]) from Util as U2 where U2.[Client Nickname 2] = ClientSummary.[Client Nickname 2] ) AS [To Date], [To Date]/[Contract] AS [% Spent], 0 AS Backlog, ClientSummary.[Total Slip Fees & Costs] AS Billed, ClientSummary.Payments AS Paid, ClientSummary.[Total A/R] AS Receivable, [Forms]![ReportMenu]![StartDate] AS [Start Date], [Forms]![ReportMenu]![EndDate] AS [End Date] FROM ClientSummary; Query 2: SELECT JobManagement_Summary.pm, JobManagement_Summary.[project #], JobManagement_Summary.Customer, JobManagement_Summary.[Job Name], JobManagement_Summary.Contract, IIf(IsNull([This Week]),0,[This Week]) AS [N_This Week], IIf(IsNull([To Date]),0,[To Date]) AS [N_To Date], [% Spent], JobManagement_Summary.Backlog, JobManagement_Summary.Billed, JobManagement_Summary.Paid, JobManagement_Summary.Receivable, JobManagement_Summary.[Start Date], JobManagement_Summary.[End Date] FROM JobManagement_Summary; When I run the report from query 2 these 3 fields don't appear. N_This Week, N_To Date and % Spent. All have no data. It isn't the IIF functions, as it doesn't matter if I have those in there or remove them. Any thoughts? If I connect directly to the first recordset it works fine, but then SQL throws the error message: Multi-level GROUP BY cause not allowed in subquery. Is there any way to get around that message to link to it directly or does anyone have ANY clue why these fields are coming back blank? I am at wits end here!

  • Is there anything wrong with my Factory class?

    - by Alex
    class PieceFactory { @SuppressWarnings("rawtypes") public Piece createPiece(String pieceType) throws Throwable{ Class pieceClass = Class.forName(pieceType); Piece piece = (Piece) pieceClass.newInstance(); return piece; } } I'm not all used to handling exceptions yet therefore I'm just throwing them, but everywhere I use a method that uses this factory it tells me I have to throw exceptions like throwable. For example, in one of my classes I have a method that instantiates a lot of objects using the method that uses the factory. I can use the method in that class by just throwing the exception, however it won't work if I try to pass a reference to that class to another class and then use the method from there. Then it forces me to try catch the exception. I probably don't need a factory but it seemed interesting and I'd like to try to use patterns. The reason I created the factory was that I have 6 subclasses of Piece and I wan't to use a method to instantiate them by passing the type of subclass I want as an argument to the method.

  • Convert Stream to IEnumerable. If possible when "keeping laziness"

    - by Binary255
    Hi, I recieve a Stream and need to pass in a IEnumerable to another method. public static void streamPairSwitchCipher(Stream someStream) { ... someStreamAsIEnumerable = ... IEnumerable returned = anotherMethodWhichWantsAnIEnumerable(someStreamAsIEnumerable); ... } One way is to read the entire Stream, convert it to an Array of bytes and pass it in, as Array implements IEnumerable. But it would be much nicer if I could pass in it in such a way that I don't have to read the entire Stream before passing it in. public static IEnumerable<T> anotherMethodWhichWantsAnIEnumerable<T>(IEnumerable<T> p) { ... // Something uninteresting }

  • Syntax error results in blank page

    - by Philipp
    I am new to wicket and trying to get some things working. One thing that annoys me a lot is that I get a blank (0 chars of text) page whenever there is a syntax error on a page. Striped down example: Test.html header stuff: doctype ... html ... head ... body ... <span wicket:id="msgTest" id="message">MSG</span> footer stuff: /body ... /html Test.java public class Test extends WebPage { public Test() { add(new Label("msgTest", "Hello, World!")); } } This will output the page as expected. Now, lets introduce an error: header stuff: doctype ... html ... head ... body ... <span wicket:id="msgTest2" id="message">MSG</span> footer stuff: /body ... /html I changed the label-id to something different then what the source-file expects. If I run this code I get the already mentioned blank page. However, for every request to a page with such a syntax error I get an error report in the log-file of around 1000+ lines. This error-report is basically just wicket-generated html of a page which describes the error. This makes me wonder why wicket isn't displaying the error-stuff instead of the blank page. I'm not very experienced with wicket but to me it somehow looks like wicket is having trouble rendering its own error-page code. It would be nice to know how one goes about finding syntax-errors with wicket. Reading through a 1000+ line error-report for a small error like a misplaced character seems a bit tedious. Thanks in advance for guiding me into the right direction :) PS: wicket-version: 1.4.9 stage: development

  • Django: cannot pass variable to included template?

    - by duy
    Hi, I got a problem where I want to use template including in Django. Here is the real example: I got 3 file: home.html (will get the context variable passed from Views), base.html (the skeleton template file) and the header.html (included by base.html). If if put the code below directly in base.html without including the header.html, the {{title}} variable passing from home is correctly called. But if I include the header.html in base.html, the {{title}} variable's value cannot be called. <title>{% block title %}{% endblock %} | {{ SITE_INFO_TITLE }}</title> Is there any solution to this problem? Thanks.

  • Parsing XML in C# from stream

    I've tried several methods, from Linq to loading the data to an XML document, but i can't seem to be able to return the result that i need. here's the example XML: <serv:message xmlns:serv="http://www.webex.com/schemas/2002/06/service" xmlns:com="http://www.webex.com/schemas/2002/06/common" xmlns:event="http://www.webex.com/schemas/2002/06/service/event"><serv:header><serv:response><serv:result>SUCCESS</serv:result><serv:gsbStatus>PRIMARY</serv:gsbStatus></serv:response></serv:header><serv:body><serv:bodyContent xsi:type="event:createEventResponse" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"><event:sessionKey>11111111</event:sessionKey><event:guestToken>111111111111111111111</event:guestToken></serv:bodyContent></serv:body></serv:message> And, here's what i've tried to do: StreamReader reader = new StreamReader(dataStream); XmlDocument doc = new XmlDocument(); doc.LoadXml(reader.ReadToEnd()); XmlNamespaceManager ns = new XmlNamespaceManager(doc.NameTable); XmlNamespaceManager ns2 = new XmlNamespaceManager(doc.NameTable); XmlNamespaceManager ns3 = new XmlNamespaceManager(doc.NameTable); ns.AddNamespace("serv", "http://www.webex.com/schemas/2002/06/service"); ns2.AddNamespace("com", "http://www.webex.com/schemas/2002/06/common"); ns3.AddNamespace("event", "http://www.webex.com/schemas/2002/06/service/event"); XmlNode node = doc.SelectSingleNode("result",ns); Yet, for some reason i cannot ever seem to return the actual result, which should be either 'SUCCESS' or 'FAILURE' based on the actual xml above. How can i do this?

  • Get all Select Elements in a Form by referencing $(this) instead of $("form select")

    - by DaveDev
    Hi Guys I'm currently getting all the Select elements that exist in a form with the following: $("form").submit(function(event) { // gather data var data = GetSelectData($("form select")); // do submit $.post($(this).attr("action"), data, ..etc) }); Instead of passing in $("form select"), is there a way I can say something like $(this).children('select') // this doesn't work, btw to get all the select elements that exist within the context of the form the submit event is executing for? This will allow me to reduce my code to the following, moving all the functionality into a common function: $("form").submit(function(event) { GatherDataAndSubmit($(this)); }); function GatherDataAndSubmit(obj) { var data = GetSelectData(obj.children('select')); $.post(obj.attr("action"), data, ..etc) } Thanks Dave

  • npgsql Leaking Postgres DB Connections: Way to monitor connections?

    - by Alan
    Background: I'm moving my application from npgsql v1 to npgsql v2.0.9. After a few minutes of running my application, I get a System.Exception: Timeout while getting a connection from the pool. The web claims that this is due to leaking connections (opening a db connection, but not properly closing them). So I'm trying to diagnose leaking postgres connections in npgsql. From the various web literature around; one way to diagnose leaking connections is to setup logging on npgsql, and look for the leaking connection warning message in the log. Problem is, I'm not seeing this message in the logs anywhere. I also found utility that monitors npgsql connections, but it's unstable and crashes. So I'm left manually inspecting code. For everyplace that creates an npgsql connection, there is a finally block disposing of it. For everyplace that opens a datareader, CommandBehavior.CloseConnection is used (and the datareader is disposed). Any other places to check or can someone recommend a way to look for leaking pool connections?

  • How do I create a random method name

    - by Russ Bradberry
    I plan on using JSONP to call an external webservice to get around the fact that I dont want to create a global function that could potentially conflict with the calling page. I thought that creating a random function name and passing it up would work. Something like this: <script src="www.foo.com/b?cb=d357534"> where cb is the callback function name, the server would return d357534({my json data}); what i want to know is how to create the random function name, im sure i could use eval but is this the best way to go about it? essentially, what i am trying to do is this: var d + Math.floor(Math.random()*1000001) = function(){...

  • const read only local copies

    - by robUK
    Hello gcc 4.4.4 c89 I am just wondering is it worth passing a const into a function. i.e. void do_something(const char *dest, const int size) The size is a read-only so I don't want to change it. However, some developers never have this as const has it is a local copy that is being used. The pointer is const as you can change the value in the calling routine. I always have a const on read-only local copies, as it confirms to anyone reading my code that it is a read-only variable. And also, when coding I don't make the mistake of changing it without realizing. Many thanks for any suggestions,

  • Creating futures using Apple's GCD

    - by jer
    I'm working on a library which implements the actor model on top of Grand Central Dispatch (specifically the C level API libdispatch). Basically a brief overview of my system is as such: Communication happens between actors using messages Multicast communication only (one actor to many actors) Senders and receivers are decoupled from one another using a blackboard where messages are pushed to. Messages are sent in the default queue asynchronously using dispatch_group_async() once a message gets pushed onto the blackboard. I'm trying to implement futures in the language right now, so I've created a new type which holds some information: A group of its own The value being 'returned' However, I have a problem since dispatch_block_t is of type void (^)(void) so it doesn't return anything. So my idea of in my future_new() function of setting up another group which can be used to execute a block returning a result, which I can store in my "value" member in my future_t structure, isn't going to work. The rest of the futures implementation is very clear, except it all depends on being able to get the value into the future back from the actor, acting on the message. When using the library, it would greatly reduce its usefulness if I had to ask users (and myself) to be aware when futures were going to be used by other parts of the system—It just isn't practical. I'm wondering if anyone can think of a way around this?

  • Lock HTML select element, allow value to be sent on submit

    - by ILMV
    I have a select box (for a customer field) on a complex order form, when the user starts to add lines to the order they should not be allowed to change the customer select box (unless all lines are deleted). My immediate thought was that I could use the disabled attribute, but when the box is disabled the selected value is no longer passed to the target. When the problem arose a while ago one of the other developers worked around this by looping through all the options and disabling all but the selected option, and sure enough the value was passed to the target and we've been using since. But now I'm looking for a proper solution, I don't want to loop through all the options because are data is expanding and it's starting to introduce performance issues. I'd prefer not to enable this / all the elements when the submit button is hit. How can I lock the input, whilst maintaining the selected option and passing that value to the target script? I would prefer a non-JavaScript solution if possible, but if needed we are running jQuery 1.4.2 so that could be used.

  • URLClassLoader does not find folders in jar if not ending with '/'?

    - by IttayD
    A 3rd party library (jersey) is trying to find Java packages by ClassLoader#findResource passing in the package name as file name (replacing dots with slashes). What I see is that if I pass a package name as 'a.b.c' (converted to 'a/b/c') it is not found, but if I pass 'a.b.c.' it is found. This translated directly to URL#inputStream that uses ZipFile which doesn't find the entry a/b/c, but finds the entry a/b/c/ I'm trying to find if this is the intended behavior or is there something wrong with my packaging (maven) or the URLs passed to the classloader (which look like jar:file://C:/.../foo.jar!/)

  • Getting Bad file descriptor when running Tornado AsyncHTTPTestCase

    - by Will
    When running a test using the Tornado AsyncHTTPTestCase I'm getting a stack trace that isn't related to the test. The test is passing so this is probably happening on the test clean up? I'm using Python 2.7.2, Tornado 2.2. The test code is: class AllServersHandlerTest(AsyncHTTPTestCase): endpoint = AllServersHandler.endpoint # '/rest/test/' def test_server_status_with_advertiser(self): on_new_host(None, '127.0.0.1') response = self.fetch(self.endpoint, method='GET') result = json.loads(response.body, 'utf8').get('data') self.assertEquals(['127.0.0.1'], result) The test passes ok, but I get the following stack trace from the Tornado server. OSError: [Errno 9] Bad file descriptor INFO:root:200 POST /rest/serverStatuses (127.0.0.1) 0.00ms DEBUG:root:error closing fd 688 Traceback (most recent call last): File "C:\Python27\Lib\site-packages\tornado-2.2-py2.7.egg\tornado\ioloop.py", line 173, in close os.close(fd) OSError: [Errno 9] Bad file descriptor Any ideas how to cleanly shutdown the test case?
