  • WPF DATAGRID CELL CONTENTS ALIGNMENT

    - by Ulhas Tuscano
    Hi, I have a WPF DataGrid control I am binding the objects of class Customer to DataGrid Rows using ObservableCollection at run time. I have set MinRowHeight="100" & I want the rows of DataGrid should be HorizontallyAligned at Center & Vertically at Left. Setting DataGrid properties VerticalContentAlignment="Center" HorizontalContentAlignment="Center" doesn't help. Code :--- System.Collections.ObjectModel.ObservableCollection cust1 = new System.Collections.ObjectModel.ObservableCollection { new Customer{FirstName="Ulhas",LastName="TUSCANO",IsMember = true ,Email="[email protected]",Status=OrderStatus.Processing }, new Customer{FirstName="Neville",LastName="TUSCANO",IsMember = true ,Email="[email protected]",Status=OrderStatus.Received }, new Customer{FirstName="Pascoal",LastName="TUSCANO",IsMember = true ,Email="[email protected]",Status=OrderStatus.None }, new Customer{FirstName="Mary",LastName="TUSCANO",IsMember = true ,Email="[email protected]",Status=OrderStatus.Received }, new Customer{FirstName="Mary",LastName="TUSCANO",IsMember = true ,Email="[email protected]",Status=OrderStatus.Received }, new Customer{FirstName="Mary",LastName="TUSCANO",IsMember = true ,Email="[email protected]",Status=OrderStatus.Received }, }; dataGrid1.ItemsSource = cust1; public class Customer { public string FirstName{get;set;} public string LastName { get; set; } public string Email { get; set; } public bool IsMember { get; set; } public OrderStatus Status { get; set; } } Any help will be greatly appreciated, Thanx

  • cookieless sessions with ajax

    - by thezver
    ok, i know you get sick from this subject. me too :( I've been developing a quite "big application" with PHP & kohana framework past 2 years, somewhat-successfully using my framework's authentication mechanism. but within this time, and as the app grown, many concerning state-preservation issues arisen. main problems are that cookie-driven sessions: can't be used for web-service access ( at least it's really not nice to do so.. ) in many cases problematic with mobile access don't allow multiple simultaneous apps on same browser ( can be resolved by hard trickery, but still.. ) requires many configurations and mess to work 100% right, and that's without the --browser issues ( disabled cookies, old browsers bugs & vulnerabilities etc ) many other session flaws stated in this old thread : http://lists.nyphp.org/pipermail/talk/2006-December/020358.html After a really long research, and without any good library/on-hand-solution to feet my needs, i came up with a custom solution to majority of those problems . Basically, i'ts about emulating sessions with ajax calls, with additional security/performance measures: state preserved by interchanging SID(+hash) with client on ajax calls. state data saved in memcache(or equivalent), indexed by SID security achieved by: appending unpredictible hash to SID egenerating hash on each request & validating it validating fingerprint of client on each request ( referrer,os,browser etc) (*)condition: ajax calls are not simultaneous, to prevent race-condition with session token. (hopefully Ext-Direct solves that for me) From the first glance that supposed to be not-less-secure than equivalent cookie-driven implementation, and at the same time it's simple, maintainable, and resolves all the cookies flaws.. But i'm really concerned because i often hear the rule "don't try to implement custom security solutions". I will really appreciate any serious feedback about my method, and any alternatives. also, any tip about how to preserve state on page-refresh without cookies would be great :) but thats small technical prob. Sorry if i overlooked some similar post.. there are billions of them about sessions . Big thanks in advance ( and for reading until here ! ).

  • Compare base class part of sub class instance to another base class instance

    - by Anders Abel
    I have number of DTO classes in a system. They are organized in an inheritance hierarchy. class Person { public int Id { get; set; } public string FirstName { get; set; } public string ListName { get; set; } } class PersonDetailed : Person { public string WorkPhone { get; set; } public string HomePhone { get; set; } public byte[] Image { get; set; } } The reason for splitting it up is to be able to get a list of people for e.g. search results, without having to drag the heavy image and phone numbers along. Then the full PersonDetail DTO is loaded when the details for one person is selected. The problem I have run into is comparing these when writing unit tests. Assume I have Person p1 = myService.GetAPerson(); PersonDetailed p2 = myService.GetAPersonDetailed(); // How do I compare the base class part of p2 to p1? Assert.AreEqual(p1, p2); The Assert above will fail, as p1 and p2 are different classes. Is it possible to somehow only compare the base class part of p2 to p1? Should I implement IEquatable<> on Person? Other suggestions?

  • WCF Datacontract, some fields do not deserialize

    - by jhersh
    Problem: I have a WCF service setup to be an endpoint for a call from an external system. The call is sending plain xml. I am testing the system by sending calls into the service from Fiddler using the RequestBuilder. The issue is that all of my fields are being deserialized with the exception of two fields. price_retail and price_wholesale. What am I missing? All of the other fields deserialize without an issue - the service responds. It is just these fields. XML Message: <widget_conclusion> <list_criteria_id>123</list_criteria_id> <list_type>consumer</list_type> <qty>500</qty> <price_retail>50.00</price_retail> <price_wholesale>40.00</price_wholesale> <session_id>123456789</session_id> </widget_conclusion> Service Method: public string WidgetConclusion(ConclusionMessage message) { var priceRetail = message.PriceRetail; } Message class: [DataContract(Name = "widget_conclusion", Namespace = "")] public class ConclusionMessage { [DataMember(Name = "list_criteria_id")] public int CriteriaId { get; set;} [DataMember(Name = "list_type")] public string ListType { get; set; } [DataMember(Name = "qty")] public int ListQuantity { get; set; } [DataMember(Name = "price_retail")] public decimal PriceRetail { get; set; } [DataMember(Name = "price_wholesale")] public decimal PriceWholesale { get; set; } [DataMember(Name = "session_id")] public string SessionId { get; set; } }

  • Getting Nested Object Property Value Using Reflection

    - by Kumar
    I have the following two classes: public class Address { public string AddressLine1 { get; set; } public string AddressLine2 { get; set; } public string City { get; set; } public string State { get; set; } public string Zip { get; set; } } public class Employee { public string FirstName { get; set; } public string MiddleName { get; set; } public string LastName { get; set; } public Address EmployeeAddress { get; set; } } I have an instance of the employee class as follows: var emp1Address = new Address(); emp1Address.AddressLine1 = "Microsoft Corporation"; emp1Address.AddressLine2 = "One Microsoft Way"; emp1Address.City = "Redmond"; emp1Address.State = "WA"; emp1Address.Zip = "98052-6399"; var emp1 = new Employee(); emp1.FirstName = "Bill"; emp1.LastName = "Gates"; emp1.EmployeeAddress = emp1Address; I have a method which gets the property value based on the property name as follows: public object GetPropertyValue(object obj ,string propertyName) { var objType = obj.GetType(); var prop = objType.GetProperty(propertyName); return prop.GetValue(obj, null); } The above method works fine for calls like GetPropertyValue(emp1, "FirstName") but if I try GetPropertyValue(emp1, "Address.AddressLine1") it throws an exception because objType.GetProperty(propertyName); is not able to locate the nested object property value. Is there a way to fix this?

  • Usercontrol losing Viewstate across Postback

    - by Robert W
    I have a user control which uses objects as inner properties (some code is below). I am having trouble with setting the attribute of the Step class programmatically, when set programmatically it is being lost across postback which would indicate something to do with Viewstate (?). When setting the property of the Step class declaratively it's working fine. Does anybody have any ideas of what this code be/what's causing it to lose the state across postback? public partial class StepControl : System.Web.UI.UserControl { [PersistenceMode(PersistenceMode.InnerProperty)] [DesignerSerializationVisibility(DesignerSerializationVisibility.Content)] [NotifyParentProperty(true)] public Step Step1 { get; set; } [PersistenceMode(PersistenceMode.InnerProperty)] [DesignerSerializationVisibility(DesignerSerializationVisibility.Content)] [NotifyParentProperty(true)] public Step Step2 { get; set; } protected void Page_Init(object sender, EventArgs e) { AddSteps(); } private void AddSteps() { } } [Serializable()] [ParseChildren(true)] [PersistChildren(false)] public class Step { [PersistenceMode(PersistenceMode.Attribute)] public string Title { get; set; } [PersistenceMode(PersistenceMode.Attribute)] public string Status { get; set; } [PersistenceMode(PersistenceMode.InnerProperty)] [TemplateInstance(TemplateInstance.Single)] [TemplateContainer(typeof(StepContentContainer))] public ITemplate Content { get; set; } public class StepContentContainer : Control, INamingContainer { } }

  • Validating DataAnnotations with Validator class

    - by Pablote
    I'm trying to validate a class decorated with dataannotation with the Validator class. It works fine when the attributes are applied to the same class. But when I try to use a metadata class it doesn't work. Is there anything I should do with the Validator so it uses the metadata class? Here's some code.. this works: public class Persona { [Required(AllowEmptyStrings = false, ErrorMessage = "El nombre es obligatorio")] public string Nombre { get; set; } [Range(0, int.MaxValue, ErrorMessage="La edad no puede ser negativa")] public int Edad { get; set; } } this doesnt work: [MetadataType(typeof(Persona_Validation))] public class Persona { public string Nombre { get; set; } public int Edad { get; set; } } public class Persona_Validation { [Required(AllowEmptyStrings = false, ErrorMessage = "El nombre es obligatorio")] public string Nombre { get; set; } [Range(0, int.MaxValue, ErrorMessage = "La edad no puede ser negativa")] public int Edad { get; set; } } this is how I validate the instances: ValidationContext context = new ValidationContext(p, null, null); List<ValidationResult> results = new List<ValidationResult>(); bool valid = Validator.TryValidateObject(p, context, results, true); thanks.

  • LINQ self referencing query

    - by Chris
    I have the following SQL query: select p1.[id], p1.[useraccountid], p1.[subject], p1.[message], p1.[views], p1.[parentid], case when p2.[created] is null then p1.[created] else p2.[created] end as LastUpdate from forumposts p1 left join ( select parentid, max(created) as [created] from forumposts group by parentid ) p2 on p2.parentid = p1.id where p1.[parentid] is null order by LastUpdate desc Using the following class: public class ForumPost : PersistedObject { public int Views { get; set; } public string Message { get; set; } public string Subject { get; set; } public ForumPost Parent { get; set; } public UserAccount UserAccount { get; set; } public IList<ForumPost> Replies { get; set; } } How would I replicate such a query in LINQ? I've tried several variations, but I seem unable to get the correct join syntax. Is this simply a case of a query that is too complicated for LINQ? Can it be done using nested queries some how? The purpose of the query is to find the most recently updated posts i.e. replying to a post would bump it to the top of the list. Replies are defined by the ParentID column, which is self-referencing.

  • How to debug a web service written in PHP?

    - by nightcoder
    Hello, I've got a nice question here :) I need to debug my web service written in PHP. Its client is written in C#. After a couple of days of searching I realized this is not an easy task. At least it seems nobody knows the right solution. What is the problem in, actually? We have 2 popular PHP debugging libraries : PHP Debugger from NuSphere and XDebug extension. The problem is they both are controlled from URL query string or with the help of cookies. For example, to enable debugging with PHP Debugger you need to add ?DBGSESSID=xxx parameter to your URL or to have DBGSESSID cookie. But when your web service is called from the external client, the client doesn't have a cookie and doesn't add DBGSESSID url parameter. So how can we debug in this situation? PS. I don't want to write to log files, see request and response headers/data or something like this. I want normal step-by-step debugging and breakpoints. Anyone?

  • Choosing random numbers efficiently

    - by Frederik Wordenskjold
    I have a method, which uses random samples to approximate a calculation. This method is called millions of times, so its very important that the process of choosing the random numbers is efficient. I'm not sure how fast javas Random().nextInt really are, but my program does not seem to benefit as much as I would like it too. When choosing the random numbers, I do the following (in semi pseudo-code): // Repeat this 300000 times Set set = new Set(); while(set.length != 5) set.add(randomNumber(MIN,MAX)); Now, this obviously has a bad worst-case running time, as the random-function in theory can add duplicated numbers for an eternity, thus staying in the while-loop forever. However, the numbers are chosen from {0..45}, so a duplicated value is for the most part unlikely. When I use the above method, its only 40% faster than my other method, which does not approximate, but yields the correct result. This is ran ~ 1 million times, so I was expecting this new method to be at least 50% faster. Do you have any suggestions for a faster method? Or maybe you know of a more efficient way of generation a set of random numbers.

  • MS SQL SELECT stored procedure according to combobox.selectedvalue

    Hello, In order to fill a datagridview according to the selectedvalue of a combobox I've tried creating a stored procedure.

  • Uploadify and rails 3 authenticity tokens

    Hi chaps, I'm trying to get a file upload progress bar working in a rails 3 app using uploadify (http://www.uploadify.com) and I'm stuck at authenticity tokens. My current uploadify config looks like <script type="text/javascript" charset="utf-8"> $(document).ready(function() { $("#zip_input").uploadify({ 'uploader': '/flash/uploadify.swf', 'script': $("#upload").attr('action'), 'scriptData': { 'format': 'json', 'authenticity_token': encodeURIComponent('<%= form_authenticity_token if protect_against_forgery? %>') }, 'fileDataName': "world[zip]", //'scriptAccess': 'always', // Incomment this, if for some reason it doesn't work 'auto': true, 'fileDesc': 'Zip files only', 'fileExt': '*.zip', 'width': 120, 'height': 24, 'cancelImg': '/images/cancel.png', 'onComplete': function(event, data) { $.getScript(location.href) }, // We assume that we can refresh the list by doing a js get on the current page 'displayData': 'speed' }); }); </script> But I am getting this response from rails: Started POST "/worlds" for 127.0.0.1 at 2010-04-22 12:39:44 ActionController::InvalidAuthenticityToken (ActionController::InvalidAuthenticityToken): Rendered /opt/local/lib/ruby/gems/1.8/gems/actionpack-3.0.0.beta3/lib/action_dispatch/middleware/templates/rescues/_trace.erb (1.0ms) Rendered /opt/local/lib/ruby/gems/1.8/gems/actionpack-3.0.0.beta3/lib/action_dispatch/middleware/templates/rescues/_request_and_response.erb (6.6ms) Rendered /opt/local/lib/ruby/gems/1.8/gems/actionpack-3.0.0.beta3/lib/action_dispatch/middleware/templates/rescues/diagnostics.erb within rescues/layout (12.2ms) This appears to be because I'm not sending the authentication cookie along with the request.

  • Setting up a "cookieless domain" to improve site performance

    - by Django Reinhardt
    I was reading in Google's documentation about improving site speed. One of their recommendations is serving static content (images, css, js, etc.) from a "cookieless domain": Static content, such as images, JS and CSS files, don't need to be accompanied by cookies, as there is no user interaction with these resources. You can decrease request latency by serving static resources from a domain that doesn't serve cookies. Google then says that the best way to do this is to buy a new domain and set it to point to your current one: To reserve a cookieless domain for serving static content, register a new domain name and configure your DNS database with a CNAME record that points the new domain to your existing domain A record. Configure your web server to serve static resources from the new domain, and do not allow any cookies to be set anywhere on this domain. In your web pages, reference the domain name in the URLs for the static resources. This is pretty straight forward stuff, except for the bit where it says to "configure your web server to serve static resources from the new domain, and do not allow any cookies to be set anywhere on this domain". From what I've read, there's no setting in IIS that allows you to say "serve static resources", so how do I prevent ASP.NET from setting cookies on this new domain? At present, even if I'm just requesting a .jpg from the new domain, it sets a cookie on my browser, even though our application's cookies are set to our old domain. For example, ASP.NET sets an ".ASPXANONYMOUS" cookie that (as far as I'm aware) we're not telling it to do. Apologies if this is a real newb question, I'm new at this! Thanks.

  • Limit the number of service calls in a RESTful application

    - by Slavo
    Imagine some kind of a banking application, with a screen to create accounts. Each Account has a Currency and a Bank as a property, Currency being a separate class, as well as Bank. The code might look something like this: public class Account { public Currency Currency { get; set; } public Bank Bank { get; set; } } public class Currency { public string Code { get; set; } public string Name { get; set; } } public class Bank { public string Name { get; set; } public string Country { get; set; } } According to the REST design principles, each resource in the application should have its own service, and each service should have methods that map nicely to the HTTP verbs. So in our case, we have an AccountService, CurrencyService and BankService. In the screen for creating an account, we have some UI to select the bank from a list of banks, and to select a currency from a list of currencies. Imagine it is a web application, and those lists are dropdowns. This means that one dropdown is populated from the CurrencyService and one from the BankService. What this means is that when we open the screen for creating an account, we need to make two service calls to two different services. If that screen is not by itself on a page, there might be more service calls from the same page, impacting the performance. Is this normal in such an application? If not, how can it be avoided? How can the design be modified without going away from REST?

  • ocunit testing on iPhone

    - by Magnus Poromaa
    Hi I am trying to get ocunit working in my project from XCode. Since I also need to debug in the unit tests I am using a script that automates the setup (see below). I just include it in the project under resources and change the name to the .ocunit file I want it to run. The problem I get is that it cant find the bundle file and therefore exists with an error. Can anyone who has a clue about XCode and objective-c take a look at it and tell me what is wrong. Also how am I supposed to produce the .ocunit file that I need to run. By setting up a new unit test target for the iPhone and add tests to it or? Hope someone has a clue since I just started ny iPhone development and need to get it up and running quickly Apple Script -- The only customized value we need is the name of the test bundle tell me to activate tell application "Xcode" activate set thisProject to project of active project document tell thisProject set testBundleName to name of active target set unitTestExecutable to make new executable at end of executables set name of unitTestExecutable to testBundleName set path of unitTestExecutable to "/Applications/TextEdit.app" tell unitTestExecutable -- Add a "-SenTest All" argument make new launch argument with properties {active:true, name:"-SenTest All"} -- Add the magic set injectValue to "$(BUILT_PRODUCTS_DIR)/" & testBundleName & ".octest" make new environment variable with properties {active:true, name:"XCInjectBundle", value:injectValue} make new environment variable with properties {active:true, name:"XCInjectBundleInto", value:"/Applications/TextEdit.app/Contents/MacOS/TextEdit"} make new environment variable with properties {active:true, name:"DYLD_INSERT_LIBRARIES", value:"$(DEVELOPER_LIBRARY_DIR)/PrivateFrameworks/DevToolsBundleInjection.framework/DevToolsBundleInjection"} make new environment variable with properties {active:true, name:"DYLD_FALLBACK_FRAMEWORK_PATH", value:"$(DEVELOPER_LIBRARY_DIR)/Frameworks"} end tell end tell end tell Cheers Magnus

  • Login to website using PHP and get text from page

    - by Anthony Garand
    I am trying to login to a website and grab content from a page you must be authenticated to see. I have done some research and have seen some examples using both cURL and stream_context_create but I cannot get either way to work. I have the url for the page to login to, and the page that contains the data I need to get. Your help is much appreciated! Here's what I'm working with: <?php $pages = array('home' => 'https://www.53.com/wps/portal/personal', 'login' => 'https://www.53.com/wps/portal/personal', 'data' => 'https://www.53.com/servlet/efsonline/index.html?Messages.SortedBy=DATE,REVERSE'); $ch = curl_init(); //Set options for curl session $options = array(CURLOPT_USERAGENT => 'Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.0)', CURLOPT_SSL_VERIFYPEER => FALSE, CURLOPT_SSL_VERIFYHOST => 2, CURLOPT_HEADER => TRUE, //CURLOPT_RETURNTRANSFER => TRUE, CURLOPT_COOKIEFILE => 'cookie.txt', CURLOPT_COOKIEJAR => 'cookies.txt'); //Hit home page for session cookie $options[CURLOPT_URL] = $pages['home']; curl_setopt_array($ch, $options); curl_exec($ch); //Login $options[CURLOPT_URL] = $pages['login']; $options[CURLOPT_POST] = TRUE; $options[CURLOPT_POSTFIELDS] = 'uid-input=xxx&pw=xxx'; $options[CURLOPT_FOLLOWLOCATION] = FALSE; curl_setopt_array($ch, $options); curl_exec($ch); //Hit data page $options[CURLOPT_URL] = $pages['data']; curl_setopt_array($ch, $options); $data = curl_exec($ch); //Output data echo $data; //Close curl session curl_close($ch); ?> Cheers, Anthony

  • When using Data Annotations with MVC, Pro and Cons of using an interface vs. a MetadataType

    - by SkippyFire
    If you read this article on Validation with the Data Annotation Validators, it shows that you can use the MetadataType attribute to add validation attributes to properties on partial classes. You use this when working with ORMs like LINQ to SQL, Entity Framework, or Subsonic. Then you can use the "automagic" client and server side validation. It plays very nicely with MVC. However, a colleague of mine used an interface to accomplish exactly the same result. it looks almost exactly the same, and functionally accomplishes the same thing. So instead of doing this: [MetadataType(typeof(MovieMetaData))] public partial class Movie { } public class MovieMetaData { [Required] public object Title { get; set; } [Required] [StringLength(5)] public object Director { get; set; } [DisplayName("Date Released")] [Required] public object DateReleased { get; set; } } He did this: public partial class Movie :IMovie { } public interface IMovie { [Required] object Title { get; set; } [Required] [StringLength(5)] object Director { get; set; } [DisplayName("Date Released")] [Required] object DateReleased { get; set; } } So my question is, when does this difference actually matter? My thoughts are that interfaces tend to be more "reusable", and that making one for just a single class doesn't make that much sense. You could also argue that you could design your classes and interfaces in a way that allows you to use interfaces on multiple objects, but I feel like that is trying to fit your models into something else, when they should really stand on their own. What do you think?

  • Automation Error upon running VBA script in Excel

    - by brohjoe
    Hi guys, I'm getting an Automation error upon running VBA code in Excel 2007. I'm attempting to connect to a remote SQL Server DB and load data to from Excel to SQL Server. The error I get is, "Run-time error '-2147217843(80040e4d)': Automation error". I checked out the MSDN site and it suggested that this may be due to a bug associated with the sqloledb provider and one way to mitigate this is to use ODBC. Well I changed the connection string to reflect ODBC provider and associated parameters and I'm still getting the same error. Here is the code with ODBC as the provider: Dim cnt As ADODB.Connection Dim rst As ADODB.Recordset Dim stSQL As String Dim wbBook As Workbook Dim wsSheet As Worksheet Dim rnStart As Range Public Sub loadData() 'This was set up using Microsoft ActiveX Data Components version 6.0. 'Create ADODB connection object, open connection and construct the connection string object. Set cnt = New ADODB.Connection cnt.ConnectionString = _ "Driver={SQL Server}; Server=onlineSQLServer2010.foo.com; Database=fooDB Uid=logonalready;Pwd='helpmeOB1';" cnt.Open On Error GoTo ErrorHandler 'Open Excel and run query to export data to SQL Server. strSQL = "SELECT * INTO SalesOrders FROM OPENDATASOURCE('Microsoft.ACE.OLEDB.12.0', & _ "'Data Source=C:\Database.xlsx; Extended Properties=Excel 12.0')...[SalesOrders$]" cnt.Execute (strSQL) 'Error handling. ErrorExit: 'Reclaim memory from the connection objects Set rst = Nothing Set cnt = Nothing Exit Sub ErrorHandler: MsgBox Err.Description, vbCritical Resume ErrorExit 'clean up and reclaim memory resources. cnt.Close If CBool(cnt.State And adStateOpen) Then Set rst = Nothing Set cnt = Nothing End If End Sub
