I am trying to specialize grid_residue for class Q64. thanks

  • How to document an XML Schema?

    - by lucas clemente
    I have developed a XML schema for an application I wrote. Now I want to document the valid structure for the end user, however I can't come up with any natural way to do this. I've seen things like xs3p, which essentially converts a xsd schema to a HTML representation, however that doesn't look like good documentation to me; the user shouldn't need to know anything about schemas to understand what he is allowed to do. Any ideas how to document this? Any programs / editors / graphical solutions or simply concepts I can build on?

  • Drupal using views with CCK custom fields

    - by jackbot
    I've got a Drupal site which uses a custom field for a certain type of node (person_id) which corresponds to a particular user. I want to create a view so that when logged in, a user can see a list of nodes 'tagged' with their person_id. I've got the view working fine, with a url of my-library/username but replacing username with a different username shows a list of all nodes tagged with that user. What I want to do is stop users changing the URL and seeing other users' tagged nodes. How can I do this? Is there somewhere where I can dictate that the only valid argument for this page is the one that corresponds with the current logged in user's username?

  • innerHTML removes attribute quotes in Internet Explorer

    - by Augustus
    When you get the innerHTML of a DOM node in IE, if there are no spaces in an attribute value, IE will remove the quotes around it, as demonstrated below: <html> <head> <title></title> </head> <body> <div id="div1"><div id="div2"></div></div> <script type="text/javascript"> alert(document.getElementById("div1").innerHTML); </script> </body> </html> In IE, the alert will read: <DIV id=div2></DIV> This is a problem, because I am passing this on to a processor that requires valid XHTML, and all attribute values must be quoted. Does anyone know of an easy way to work around this behavior in IE?

  • StringTokenizer problem of tokenizing

    - by Mr CooL
    String a ="the STRING TOKENIZER CLASS ALLOWS an APPLICATION to BREAK a STRING into TOKENS.  "; StringTokenizer st = new StringTokenizer(a); while (st.hasMoreTokens()){ System.out.println(st.nextToken()); Given above codes, the output is following, the STRING TOKENIZER CLASS ALLOWS an APPLICATION to BREAK a STRING into TOKENS.  My only question is why the "STRING TOKENIZER CLASS" has been combined into one token???????? When I try to run this code, System.out.println("STRING TOKENIZER CLASS".contains(" ")); It printed funny result, FALSE It sound not logical right? I've no idea what went wrong. I found out the reason, the space was not recognized as valid space by Java somehow. But, I don't know how it turned up to be like that from the front processing up to the code that I've posted.

  • Insert new relationship data in core data

    - by michael
    Hoping someone can shed some light on what I might be doing wrong here. Trying to add an "event" to a list of events, represented by a one to many (inverse) relationship: MyEvents <--- Event This is the code: MyEvents *myEvents = (MyEvents *)[NSEntityDescription insertNewObjectForEntityForName:@"MyEvents" inManagedObjectContext:context]; NSLog(@"MYEVENTS: %@", myEvents); NSLog(@"EVENT: %@", event); [myEvents addEventObject:event]; My context is fine, and both the myEvents and event print perfectly valid information. When I try to add the event that I have (which is passed into this view controller, having been retrieved from core data previously) with this code [myEvents addEventObject:event]; It falls over with *** -[NSComparisonPredicate evaluateWithObject:]: message sent to deallocated instance MyEvents and Event are just the default generated code. MyEvents contains only the relationship to event. Thanks.

  • Raspberry Pi cluster, neuron networks and brain simulation

    - by jokoon
    Since the RBPI (Raspberry Pi) has very low power consumption and very low production price, it means one could build a very big cluster with those. I'm not sure, but a cluster of 100000 RBPI would take little power and little room. Now I think it might not be as powerful as existing supercomputers in terms of FLOPS or others sorts of computing measurements, but could it allow better neuronal network simulation ? I'm not sure if saying "1 CPU = 1 neuron" is a reasonable statement, but it seems valid enough. So does it mean such a cluster would more efficient for neuronal network simulation, since it's far more parallel than other classical clusters ?

  • Linq : problem with primary key

    - by Nickson
    I get the following error message The table/view 'TABLE1' does not have a primary key defined and no valid primary key could be inferred. This table/view has been excluded. To use the entity you will need to review your schema, add the correct keys and uncomment it when I try to add a view to an Entity Data Model. For testing, I have created a very simple view and I still get the error. below is the view definition SELECT DISTINCT TOP (100) PERCENT MIN(id) AS Expr4, MIN(EmpNo) AS Expr1, MIN(Name) AS Expr2, MIN(Category) AS Expr3 FROM dbo.MYView1 GROUP BY id does any one know of a simple work around. I have looked at this thread http://stackoverflow.com/questions/745341/can-ms-sql-views-have-primary-and-foriegn-keys but in my scenario, what is recommended is not applicable. If I could only have the view added to the Model.

  • Javascript Array Scope - newbie here

    - by Gianluca
    So, I am learning Javascript while playing white Google Calendar APIs and I just can't figure how this piece of code is working this way: var entriesResult = []; var data = new Date(2010,3,22,17,0,0); var callback = function(result) { var entries = result.feed.getEntries(); if (entries.length != 0) { entriesResult = eventsManager(entries, 0, data); window.alert("inner entriesResult " + entriesResult.length); } } this.service.getEventsFeed(this.query, callback, handleGDError); window.alert("outer entriesResult " + entriesResult.length); eventsManager() is a function that returns an array of Objects. getEventsFeed() it's an API function: it queries the service and pass a "feed root" (a feed with selected items) to the callback function. Why the first alert (inner..) outputs a valid entriesResult.length while the second one (outer..) always outputs a 0? I tought javascript arrays are always passed by reference, what's wrong whit my code? Thank you :)

  • How to secure licensekey generation

    - by Jakob Gade
    Scenario, simplified for brevity: A developer creates an application for a customer. The customer sells this app to end-users. The app requires a license key to run, and this key is generated by the customer for each end-user with a simple tool created by the developer. The license key contains an expiry date for the license and is encrypted so the end-user can’t tamper with it. The problem here is that the developer (or anybody who has a copy of the license key generator) can easily create valid license keys. Should this generator fall into the wrong hands, it could spell disaster for the customers business. Ideally, the customer would have to use a password to create new license keys. And this password would be unknown to the developer, and somehow baked into the decryption algorithm in the application so it will fail if an attempt to use an unauthorized key is made. How would you implement a solution for this problem that is both transparent and secure?

  • Ruby email_veracity_checker getting Recipient OK for invalid emails

    - by digger69
    I was testing out email_veracity_checker from rails console and found that when I tested a google apps domain (w/ catchall), yahoo and another company domain, the smtp server always returned 250 recipient ok for invalid emails (wellformed, but bogus). It seems that these servers are always returning OK perhaps to prevent email harvesting. But it does seem to raise the question 'why even validate up-front', is this approach even valid in today's environment? Note: gmail did return 550 email account doesn't exist for invalid. related to How check if an email exist without send in Ruby? Use of email_veracity_checker send-in-ruby-use-of-email-veracity-checker I appreciate your thoughts.

  • How can I access an ASP.Net 2.0 web service using VB Script?

    - by Steve Hiner
    I'm trying to find a way to access a web service from a VB Script .vbs file running under wscript.exe. I pulled some sample code from Microsoft but it gives me an error. Dim SOAPClient, Response Set SOAPClient = createobject("MSSOAP.SOAPClient") SOAPClient.mssoapinit("https://www.domain.com/Folder/Service.asmx?WSDL") On that last line I get an error message: WSDLReader: No valid schema specification was found. This version of the SOAP Toolkit only supports 1999 and 2000 XSD schema specifications After getting that message I installed the SOAP 3.0 SDK to make sure I have the most recent version (since it's now deprecated for .Net) but I still get the same error. The reason it needs to be in VB Script is because it's going to be used in a program over which I have no control and it only supports VB Script. Is there a way to get VB Script to be able to parse a newer WSDL file? I do have the source code for the web service. Is there something I can change in the web service to make it schema compatible with the SOAP toolkit?

  • .NET WebService Custom Attribute

    - by DownChapel
    I would like to add a custom attribute to a asmx web service to determine if the request is valid based on the client IP address. This is a similar idea to the AuthorizeAttribute in ASP.NET MVC. Is there anywhere (e.g. a HTTP module) I can put the code to look at the attribute on the webservice and decide whether to allow the request or not? In my web.config the handler for asmx is the ScriptHandlerFactory from the System.Web.Extensions dll. I have already implemented the functionality with a HTTP module and a config file with a list of allowed URLs, but I would prefer to get rid of the config file and just add an attribute to the webservice class. Thanks

  • Modern way to handle and validate POST-data in MVC 2

    - by zerkms
    There are a lot of articles devoted to working with data in MVC, and nothing about MVC 2. So my question is: what is the proper way to handle POST-query and validate it. Assume we have 2 actions. Both of them operates over the same entity, but each action has its own separated set of object properties that should be bound in automatic manner. For example: Action "A" should bind only "Name" property of object, taken from POST-request Action "B" should bind only "Date" property of object, taken from POST-request As far as I understand - we cannot use Bind attribute in this case. So - what are the best practices in MVC2 to handle POST-data and probably validate it. UPD: After Actions performed - additional logic will be applied to the objects so they become valid and ready to store in persistent layer. For action "A" - it will be setting up Date to current date.

  • Regular expression replace in PL/pgSQL

    - by dreamlax
    If I have the following input (excluding quotes): "The ancestral territorial imperatives of the trumpeter swan" How can I collapse all multiple spaces to a single space so that the input is transformed to: "The ancestral territorial imperatives of the trumpeter swan" This is going to be used in a trigger function on insert/update (which already trims leading/trailing spaces). Currently, it raises an exception if the input contains multiple adjacent spaces, but I would rather it simply transforms it into something valid before inserting. What is the best approach? I can't seem to find a regular-expression replace function for PL/pgSQL. There is a text_replace function, but this will only collapse at most two spaces down to one (meaning three consecutive spaces will collapse to two). Calling this function over and over is not ideal.

  • Java servlet and JSP accessing the same session bean

    - by Mykola Golubyev
    Let's say I have simple Login servlet that checks the passed name and creates User object and stores it in a session. User user = new User(); user.setId(name); request.getSession().setAttribute("user", user); response.sendRedirect("index.jsp"); In the index.jsp page I access the user object through jsp:useBean <jsp:useBean id="user" scope="session" class="package.name.User"/> <div class="panel"> Welcome ${user.id} </div> It works so far. The question: is this a valid usage or it is just current implementation uses the same name as the jsp bean id when stores and looks for a bean in a session?

  • How do I detect a click event on a google map through an overlay?

    - by freddoo
    My problem is that I have a circle map overlay but I want to be able to move the circle by clicking the map to set the new center, the actual problem is that when I click on the overlay and call my method 'setCenter(overlay, latlng) ' , I get undefined latlang and a valid overlay. here is an example that can illustrate the problem, if you click the map a polygon is drawn and if you click inside the polygon no new polygon is drawn, if you click anywhere else on the map a polygon is drawn http://code.google.com/apis/maps/documentation/examples/polygon-simple.html I want to be able to click the polygon and draw a new one making them overlap thanks

  • Are there any syntax errors in the code snippet here?

  • recaptcha asp.net always returns invalid

    - by Curtis White
    The reCaptcha example for ASP.NET does not seem to work. I followed the instructions but it always returns false, "The verification words are incorrect.". The entries are good. I'm using localhost as the site but am not getting any public/private key errors which I did get when adding a bad key (as a test). I've seen this error reported a lot but no good answers. Some suggest to call the validate on the control before checking to see if it is valid but this did not work for me.

  • Masked Edit Extender Format Issue

    - by Kumar
    I am using an ASP.NET AJAX Masked Edit Extender to format phone numbers <asp:TextBox ID="tbPhoneNumber" runat="server" /> <ajaxToolkit:MaskedEditExtender TargetControlID="tbPhoneNumber" Mask="(999)999-9999" MaskType="Number" InputDirection="LeftToRight" ClearMaskOnLostFocus="false" ClearTextOnInvalid="false" runat="server" AutoComplete="false" /> On the page load event I am trying to populate the phone textbox as follows: protected void Page_Load(object sender, EventArgs e) { tbPhoneNumber.Text = "(394)456-310"; } So there is one number which is missing at the end to make it a valid phone number. When the page loads I expected the value in the textbox to be (394)456-310_ But it displays (_39)445-6310 Why is this happening?

  • Cleanup for control inside a FlowDocument

    - by Thorarin
    I have a custom control that I use inside a FlowDocument. The control uses a System.Drawing.ImageAnimator to display transparent, animated GIF images. Why is this such a pain in the butt in WPF anyway? :P In my original implementation, this was causing memory leaks when a paragraph containing the control was being deleted from the document, because the ImageAnimator kept a reference to the control for event handling. I've now implemented a WeakEventManager pattern which seems to indeed fix the leak itself, but I would like to stop "OnFrameChanged" events from being fired if a particular animated GIF is not currently in the document, instead of relying on the garbage collector to eventually collect the control objects and my event manager to notice that there no longer are valid listeners to the event. Basically, I would like to take a more active role in this and have the control react to being removed from the FlowDocument. Is there some way to do this? I've been unable to find it. OnVisualParentChanged doesn't get fired, because the direct parent (a Paragraph) is unchanged.

  • SQL Server: Must numbers all be specified with latin numeral digits?

    - by Ian Boyd
    Does SQL server expect numbers to be specified with digits from the latin alphabet, e.g.: 0123456789 Is it valid to give SQL Server digits in other alphabets? Rosetta Stone: Latin: 01234567890 Arabic: ?????????? Bengali: ?????????? i know that the client (ADO) will convert 8-bit strings to 16-bit unicode strings using the current culture. But the client is also converting numbers to strings using their current culture, e.g.: SELECT * FROM Inventory WHERE Quantity > ???,?? Which throws SQL Server for fits. i know that the server/database has it's defined code page and locale, but that is for strings. Will SQL Server interpret numbers using the active (or per-login specified) locale, or must all numeric values be specifid with latin numeral digits?

  • How do I get an unexpanded REG_EXPAND_SZ string from a remote registry?

    - by dalehhirt
    I am currently using RegistryKey.GetValue(string name, object defaultValue, RegistryValueOptions options) with RegistryValueOptions.DoNotExpandEnvironmentNames for the options value. However, this is only valid when run on the local machine. Digging down via Reflector, I find it expands the strings locally. Which means that irrespective of the setting, the strings come down remotely already expanded. Has anyone come across a solution to this that does not require running a process directly on the remote machine to get a REG_EXPAND_SZ value? Update: I attempted to use WMI's StdRegProv provider to gain access, but it still expands the strings before sending them back.

  • Is it legal to stub the #class method of a Mock object when using RSpec in a Ruby on Rails applicati

    - by MiniQuark
    I would like to stub the #class method of a mock object: describe Letter do before(:each) do @john = mock("John") @john.stub!(:id).and_return(5) @john.stub!(:class).and_return(Person) # is this ok? @john.stub!(:name).and_return("John F.") Person.stub!(:find).and_return(@john) end it.should "have a valid #to field" do letter = Letter.create!(:to=>@john, :content => "Hello John") letter.to_type.should == @john.class.name letter.to_id.should == @john.id end [...] end On line 5 of this program, I stub the #class method, in order to allow things like @john.class.name. Is this the right way to go? Will there be any bad side effect? Edit: The Letter class looks like this: class Letter < ActiveRecord::Base belongs_to :to, :polymorphic => true [...] end I wonder whether ActiveRecord gets the :to field's class name with to.class.name or by some other means. Maybe this is what the class_name method is ActiveRecord::Base is for?
