  • 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.

  • Firefox ignoring padding

    - by iMaster
    I have this CSS code: #tweet-container{ width: 290px; height: 272px; border: 1px solid #CCC; color: #CCC; font-size: 28px; text-align: center; letter-spacing: -2px; min-height: 10px; display: table-cell; vertical-align: middle; padding: 15px; } But firefox doesn't seem to recognize the top and bottom padding. Safari and Chrome both show it normally, and even in Firebug when I add padding-top: it doesn't work. Its like its not a valid statement or something. Is there something I'm missing?

  • How do I load SciLexer.dll in Visual Studio 2008 Designer, on Windows 7 64-bit?

    - by Filini
    We develop a WinForm application using Scintilla.NET (1.7) component, which uses SciLexer.dll (unamnaged). At run-time, we distribute both 32bit and 64bit SciLexer.dll, and we load the correct one when the application starts (everything works fine). On our new development environments (Windows 7 64-bit), all our solutions build and run just fine, but the WinForm visual designer does not load our forms/controls which use Scintilla.NET, because it cannot load the correct SciLexer.dll: Window class name is not valid. at System.Windows.Forms.NativeWindow.WindowClass.RegisterClass() at System.Windows.Forms.NativeWindow.WindowClass.Create(String className, Int32 classStyle) at System.Windows.Forms.NativeWindow.CreateHandle(CreateParams cp) at System.Windows.Forms.Control.CreateHandle() at System.Windows.Forms.Control.get_Handle() at Scintilla.ScintillaControl.SendMessageDirect(UInt32 msg, IntPtr wParam, IntPtr lParam) at Scintilla.ScintillaControl.SendMessageDirect(UInt32 msg) at Scintilla.ScintillaControl.get_CodePage() at Scintilla.ScintillaControl..ctor(String sciLexerDllName) at Scintilla.ScintillaControl..ctor() Where does Visual Studio 2008 look for unmanaged libraries? I tried putting the 64-bit SciLexer.dll in SysWOW64, in the folder where ScintillaNET.dll is referenced, adding a folder in PATH system variable, adding a folder reference in the project, but I keep getting this error. Any help is appreciated.

  • How to create Encryption Key for Encryption Algorithms?

    - by Akash Kava
    I want to use encryption algorithm available in .Net Security namespace, however I am trying to understand how to generate the key, for example AES algorithm needs 256 bits, that 16 bytes key, and some initialization vector, which is also few bytes. Can I use any combination of values in my Key and IV? e.g. all zeros in Key and IV are valid or not? I know the detail of algorithm which does lots of xors, so zero wont serve any good, but are there any restrictions by these algorithms? Or Do I have to generate the key using some program and save it permanently somewhere?

  • 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.

  • Authkit - deferring action for HTTP '401' response to client application

    - by jon
    Form, Redirect and Forward all send an unauthenticated user to a Form on a login page specified within an Authkit middleware application. I'd like to allow a client application to request a service via XHR and then present a custom 'client side' form if a HTTP status code of 401 is returned, which would then post to Authkit for authentication until valid authentication/authorization occured. Specifically, 1) a jquery $.get request might request a resource. 2) if an Authkit cookie check confirmed previous authorization the content would be returned. 3) if not I would like Authkit to simply return the '401 response' (and not redirect to another page, or return a form template) where a client side exception handler would notify the user and present an authentication form. Can Authkit work like this?

  • Java Inter Application Form Communication Observer Pattern

    - by ikurtz
    Observer pattern? Where do i get examples of this in Java (i know google but was hoping for some personal insight also.) On to a proper explanation of my issue: i have 3 forms/windows. "board" is the main form that loads as the application. "chat" is where the text chat takes place. "network" is where network connection is established. i have the game (connect4) working locally and i would like to implement a networked version of it also. my idea is maybe it is related to Observer pattern to have a thread (or something) monitoring network state during runtime and update the chat and board forms of the current network status as well as delivering received data from the network. are my ideas valid? or how should i go about establishing network and network status updates throughout the application? thank you for your input.

  • Button in gridview

    - by Rajeev
    I'm using a button in a template field of gridview. On button click I want to redirect to another page but it throws an exception: Invalid postback or callback argument. Event validation is enabled using in configuration or <%@ Page EnableEventValidation="true" % in a page. For security purposes, this feature verifies that arguments to postback or callback events originate from the server control that originally rendered them. If the data is valid and expected, use the ClientScriptManager.RegisterForEventValidation method in order to register the postback or callback data for validation. What can I do to resolve this problem?

  • 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?

  • AudioQueueOfflineRender returning empty data

    - by hyn
    I'm having problems using AudioQueueOfflineRender to decode AAC data. When I examine the buffer after the call, it is always filled with empty data. I made sure the input buffer is valid and packet descriptions are provided. I searched and found that a few others have had the same problem: http://lists.apple.com/archives/Coreaudio-api/2008/Jul/msg00119.html Also, the inTimestamp argument doesn't make sense to me. Why should the renderer care where in the audio the beginning of the buffer corresponds to? The function throws an error if I pass in NULL, so I pass in the timestamp anyway.

  • Ignore certificate errors when requesting a URL in Java

    - by Ryan Elkins
    I'm trying to print a URL (without having a browser involved at all) but the URL is currently throwing the following: javax.net.ssl.SSLHandshakeException: sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target I'm calling the URL using a JEditorPane's setPage method, which just takes a URL as a parameter. Assuming I can't change anything server side and I still need to get to this resource, how would I go about ignoring the certificate error (or something else that gets me to my goal)? Accessing this URL via a browser tells me the site is untrusted and asks me if I want to proceed.

  • Inserting Rows in Relationship using a Strongly Typed DataSet

    - by Manuel Faux
    I'm using ADO.NET with a strongly typed dataset in C# (.NET 3.5). I want to insert a new row to two tables which are related in an 1:n relation. The table Attachments holds the primary key part of the relation and the table LicenseAttachments holds the foreign key part. AttachmentsDataSet.InvoiceRow invoice; // Set to a valid row, also referenced in InvoiceAttachments AttachmentsDataSet.AttachmentsRow attachment; attachment = attachmentsDataSet.Attachments.AddAttachmentsRow("Name", "Description"); attachmentsDataSet.InvoiceAttachments.AddInvoiceAttachmentsRow(invoice, attachment); Of course when I first update the InvoicesAttachments table, I'll get a foreign key violation from the SQL server, so I tried updating the Attachments table first, which will create the rows, but will remove the attachment association in the InvoiceAttachments table. Why? How do I solve this problem?

  • Fortran intent(inout) v's no intent

    - by Andrew Walker
    Good practice dictates that subroutine arguments in Fortran should each have a specified intent (i.e. intent(in), intent(out) or intent(inout) as described this question): subroutine bar (a, b) real, intent(in) :: a real, intent(inout) :: b b = b + a ... However, not specifying an intent is valid Fortran: subroutine bar (a, b) real, intent(in) :: a real :: b b = b + a ... Are there any real differences beyond compile time checking for an argument specified as intent(inout) and an argument without a specified intent? Is there anything I should worry about if I'm retrofitting intents to older, intent free, code?

  • Reducing piracy of iPhone applications

    - by Alex Reynolds
    What are accepted methods to reduce iPhone application piracy, which do not violate Apple's evaluation process? If my application "phones home" to provide the unique device ID on which it runs, what other information would I need to collect (e.g., the Apple ID used to purchase the application) to create a valid registration token that authorizes use of the application? Likewise, what code would I use to access that extra data? What seem to be the best available technical approaches to this problem, at the present time? (Please refrain from non-programming answers about how piracy is inevitable, etc.)

  • Validating only selected fields using ASP.NET MVC 2 and Data Annotations

    - by thinknow
    I'm using Data Annotations with ASP.NET MVC 2 as demonstrated in this post: http://weblogs.asp.net/scottgu/archive/2010/01/15/asp-net-mvc-2-model-validation.aspx Everything works fine when creating / updating an entity where all required property values are specified in the form and valid. However, what if I only want to update some of the fields? For example, let's say I have an Account entity with 20 fields, but I only want to update Username and Password? ModelState.IsValid validates against all the properties, regardless of whether they are referenced in the submitted form. How can I get it to validate only the fields that are referenced in the form?

  • Reverse engineer an ORM

    - by Oren Mazor
    Given a [mysql] database with a given schema, is it possible to generate an ORM interface for it? doesn't matter if its php, python or perl. in other words, I have a database and I have to ask it a few questions. while I could just craft a bunch of SQL queries (okay, several dozen), this is way more interesting to think about. is this a valid question, even? I have no design background with ORMs, but I've used a few (django's, symfony's, etc).

While if I copy the URL to the browser I get the result and I see the exception. I want to detect if the user is logged in and the session data is valid. What might be wrong?

  • Partial match in MaskFormatter for jFormattedTextField

    - by Toto
    How do I set up the MaskFormatter and the JFormattedTextField in order to allow partial matches? For example: I want the user to be able to enter numbers with this mask "## ###### ####", so if the user enters '123456789123' the formatter changes it to '12 345678 9123'. However, I also want the user to be able to enter '12346578', be converted to '12 345678' and still be a valid value (so I can get it using jFormatedTextField1.getValue()) This is part of my code (most of it generated by Netbeans): private javax.swing.JFormattedTextField jFormattedTextField1; // ... try { jFormattedTextField1.setFormatterFactory(new DefaultFormatterFactory(new MaskFormatter("## ###### ####"))); } catch (java.text.ParseException ex) { ex.printStackTrace(); } I've tried setting the focusLostBehavior to PERSIST so the value is not cleard after exiting the jFormattedTextField1, but that way I get a null when using the calling jFormattedTextField1.getValue()

  • developing iphone apps on windows is it worth the hassel

    - by kalpaitch
    I'm only after a simple solution and won't be developing anything particularly complex. But I'm wondering whether the hassals of developing an iPhone app NOT on MacOS are really that significant to avoid giving it a shot. Bearing in mind that I do have access to a mac every now and again. So I would be able to compile it using the official Apple supported SDK, but I just want to be able to develop it in my own environment (windows laptop). I heard someone mention a while ago that there are various objective C compilers that allow writing code in various other web technologies as well. Are these really valid. And am I alone in thinking Apple's whole attitude towards this is totally imoral. Charging $200 for the privelege of having your app unequivocally rejected etc etc and then not being allowed to look directly at Steve Jobs or his golden retrievers.

  • comparator with null values.

    - by pvgoddijn
    Hi, We have some code wich sorts a list of addresses based on the distance between their coordinates. this is done through collections.sort with a custom comparator. However from time to time an adress without coordinates is in the list causing a NullPointerException. My initial idea to fix this was to have the comparator return 0 as dististance for addresses where at least one of the coordinates is null. I fear this might lead to corruption of the order the 'valid' elements in the list. so is returning a '0' values for null data in a comparator ok, or is there a cleaner way to resolve this.

  • How do you implement Software Transactional Memory?

    - by Joseph Garvin
    In terms of actual low level atomic instructions and memory fences (I assume they're used), how do you implement STM? The part that's mysterious to me is that given some arbitrary chunk of code, you need a way to go back afterward and determine if the values used in each step were valid. How do you do that, and how do you do it efficiently? This would also seem to suggest that just like any other 'locking' solution you want to keep your critical sections as small as possible (to decrease the probability of a conflict), am I right? Also, can STM simply detect "another thread entered this area while the computation was executing, therefore the computation is invalid" or can it actually detect whether clobbered values were used (and thus by luck sometimes two threads may execute the same critical section simultaneously without need for rollback)?

  • ObjectContext ConnectionString Sqlite

    - by codegarten
    I need to connect to a database in Sqlite so i downloaded and installed System.Data.SQLite and with the designer dragged all my tables. The designer created a .cs file with public class Entities : ObjectContext and 3 constructors: 1st public Entities() : base("name=Entities", "Entities") this one load the connection string from App.config and works fine. App.config <connectionStrings> <add name="Entities" connectionString="metadata=res://*/Db.TracModel.csdl|res://*/Db.TracModel.ssdl|res://*/Db.TracModel.msl;provider=System.Data.SQLite;provider connection string=&quot;data source=C:\Users\Filipe\Desktop\trac.db&quot;" providerName="System.Data.EntityClient" /> </connectionStrings> 2nd public Entities(string connectionString) : base(connectionString, "Entities") 3rd public Entities(EntityConnection connection) : base(connection, "Entities") Here is the problem, i already tried n configuration, already used EntityConnectionStringBuilder to make the connection string with no luck. Can you please point me in the right direction!? EDIT(1) How can i construct a valid connection string?!
