  • RenderAction in an HtmlHelperExtension Method?

    - by TimLeung
    I am trying to call the RenderAction Extension Method within my own Html Helper: System.Web.Mvc.Html.ChildActionExtensions.RenderAction(helper, "account", "login"); this is so that along with some additional logic, I would like all html helpers to use a common method name structure when calling it on the view: <%= Html.CompanyName().RenderAccount() %> but the problem I am having is that, asp.net will complain about not finding the actual route it needs to process. It does not take in the parameters of "controller" to be used as the action and "login" to be used as the action. It seems to only reference the current route. Any ideas how I can package up the RenderAction?

  • C#, weird optimization

    - by Snake
    Hi, I'm trying to read my compiled C# code. this is my code: using(OleDbCommand insertCommand = new OleDbCommand("...", connection)) { // do super stuff } But! We all know that a using gets translated to this: { OleDbCommand insertCommand = new OleDbCommand("...", connection) try { //do super stuff } finally { if(insertCommand != null) ((IDisposable)insertCommand).Dispose(); } } (since OleDbCommand is a reference type). But when I decompile my assembly (compiled with .NET 2.0) I get this in Resharper: try { insertCommand = new OleDbCommand("", connection); Label_0017: try { //do super stuff } finally { Label_0111: if ((insertCommand == null) != null) { goto Label_0122; } insertCommand.Dispose(); Label_0122:; } I'm talking about this line: if ((insertCommand == null) != null). True is not null, it never is, nor is false. So how is my object disposed properly? WTF? Thanks! -Kristof

  • Expected specifier-qualifier-list before ... only in classes in a certain folder

    - by funkybro
    Hi Classes in my iPhone project are organised within folders on the filesystem, these correspond to groups (for each folder) in xcode. My problem is that there seems to be a particular class which classes in a particular group/folder cannot make reference to; the compiler complains of "Expected specifier-qualifier-list...". This happens on any class within this group, and also when I create a new class within this group and try and import the offending class like so: #import <Foundation/Foundation.h> #import "MyClass.h" @interface TryingToImport : NSObject { MyClass *myClass; // Expected specifier-qualifier-list before 'MyClass' } Creating an identical class in any other group works OK. I understand this error message is usually due to cyclical import references, I have checked over and over and there don't seem to be any of these. I assume I have inadvertantly configured the offending group to be different to the others in some way but I can't figure out how. Help please!

  • Any implementations of graph st-ordering or ear-decomposition?

    - by chang
    I'm in the search for an implementation of an ear-decomposition algorithm (http://www.ics.uci.edu/~eppstein/junkyard/euler/ear.html). I examined networkx and didn't find one. Although the algorithm layout is vaguely in my mind, I'd like to see some reference implementation, too. I'm aware of Ulrik Brandes publication on a linear time Eager st-ordering algorithm, which results in an ear decomposition as a side product, if I understand correctly (it even includes pseudocode, which I'm trying to base my implementation on). Side problem: First step could be an st-ordering of a graph. Are there any implementations for st-ordering algorithms you know? Thanks for your input. I'd really like to contribute e.g. to networkx by implementing the ear-decomposition algorithm in python.

  • Converting DAO to ADO

    - by webworm
    I am working with an Access 2003 database that has a subroutine using DAO code. This code loops through the table definitions and refreshes the ODBC connection string. I would like to convert this to ADO so I do not have to reference the DAO object library. Here is the code ... Public Sub RefreshODBCLinks(newConnectionString As String) Dim db As DAO.Database Dim tb As DAO.TableDef Set db = CurrentDb For Each tb In db.TableDefs If Left(tb.Connect, 4) = "ODBC" Then tb.Connect = newConnectionString tb.RefreshLink Debug.Print "Refreshed ODBC table " & tb.Name End If Next tb Set db = Nothing MsgBox "New connection string is " & newConnectionString, vbOKOnly, "ODBC Links refreshed" End Sub The part I am unsure of is how to loop through the tables and get/set their connection strings.

  • WCF error service error message with shared classes

    - by sevenalive
    Source code: http://code.google.com/p/sevenupdate/source/browse/#hg/Source/SevenUpdate.Base SevenUpdate.Base.Sui cannot be used since it does not match imported DataContract. Need to exclude this type from referenced types. Now I tried unchecking reuse reference types and I was able to get my project to compile. but when sending a collection from the client it was never received or couldn't be deserialized on the server end. I really need this to work. Any help would be appreciated, the fullsource code is provided by google code.

  • Spring 3 - Custom Security

    - by Eqbal
    I am in the process of converting a legacy application from proprietary technology to a Spring based web app, leaving the backend system as is. The login service is provided by the backend system through a function call that takes in some parameter (username, password plus some others) and provides an output that includes the authroizations for the user and other properties like firstname, lastname etc. What do I need to do to weave this into Spring 3.0 security module. Looks like I need to provide a custom AuthenticationProvider implementation (is this where I call the backend function?). Do I also need a custom User and UserDetailsService implementation which needs loadUserByName(String userName)? Any pointers on good documentation for this? The reference that came with the download is okay, but doesn't help too much in terms of implementing custom security.

  • Programming against WSDL without access to actual webservice

    - by Frode Lillerud
    I'm going to use C# to read data from a few webservices. I've done that many times before, but those times I've had direct access to the webservices from my development machine. In this project I've just been sent a .wsdl file, and a couple of .xsd files for the webservice they have in their local intranet. I've seen that I can use "Add Web Reference", and point directly to the .wsdl file, so that a C# class is created. But how can I really test it? I'd like to return some dummy data that I can visualize while I develop. Any tips for this situation?

  • How do you add a row to a databound datagridview using the datagridview in the gui?

    - by IsaacB
    Hi guys, I've bound a datagridview to a collection of objects. It's giving me a null reference exception when I try to add a new row to a collection (empty or otherwise) using the gui. More specifically, when there is a write event it does this. How can I override the behavior of the write event and manually add all of the columns contents to the object collection? I could disable the add new row feature and make an add button, but the built in datagridview row add looks so much more slick.

  • Google app engine - what is the lifecycle of PersistenceManager?

    - by Domchi
    What is the preferred way of using GAE datastore PersistenceManager for web app? GAE instructions are a bit ambiguous on the matter. Do I instantiate PersistenceManagerFactory for each RPC call, or do I use only one factory for all requests? Do I call PMF.get().getPersistenceManager(), or do I call PMF.get().getPersistenceManagerProxy()? Do I close PM after each RPC call, or do I leave it open? What are you guys doing? Furthermore, I'm not certain how GAE handles 30-second-per-request limit. Is it even possible to reference the same PM between requests?

  • ASP MVC: Custom Validation Attribute

    - by user323395
    I'm trying to write my own Custom Validation attribute but i'm having some problems. The attribute i'm trying to write is that when a user logs in, the password will be compared against the confirmation password. namespace EventCompanion.Data.Attributes { public class ComparePassword : ValidationAttribute { public string PasswordToCompareWith { get; set; } public override bool IsValid(object value) { if (PasswordToCompareWith == (string)value) { return true; } return false; } } Now my problem is when i'm trying to set the attribute like this in the model file: [Required] [ComparePassword(PasswordToCompareWith=ConfirmPassword)] public string Password { get; set; } [Required] public string ConfirmPassword { get; set; } } I get the following error: Error 1 An object reference is required for the non-static field, method, or property 'Project.Data.Models.GebruikerRegistreerModel.ConfirmPassword.get' It seems that VS is not accepting the confirmpassword in the "PasswordToCompareWith=ConfirmPassword" part Now my question: What am i doing wrong? Thanks in advance!!!

  • With Eclipse, in a PHP project with SVN, how to "tell" Eclipse to find autocompletion choice only in

    - by ranskalainen
    Hello, Using Eclipse on a PHP Project, I recently created a tag on my SVN. Since that day, let's say I'm working on a class in my trunk, when I ctrl+space in my code, Eclipse is getting really really slow (sometimes even freeze), and if I'm lucky, it will give me 2 responses for autocompletion : One referencing some method/class from the tag, one referencing method/class from the trunk. But right now, only the reference from the trunk would be useful for me. Is there a way to limit where Eclipse parse the code to give back autocompletion suggestion ? Thank you

  • Best solution for exporting Word documents to PDF programatically (without using a "software printer

    - by mbmccormick
    I'm looking for a way to export a Word document as a PDF. I would like to do this without the use of a "software printer" (such as CutePDF, etc.) and stick to reference assemblies if at all possible. I'm using Microsoft Office Interop Assemblies to generate a Word Document which I save to a temporary directory. So its not necessary for this solution to interact directly with Microsoft Office, unless it needs to. Any help or feedback you might have would be greatly appreciated! Thanks!

  • How to determine which class has called a function

    - by dannyc
    Hi, I am working on a Flex Front End at the moment, and have been using the Parsley framework for passing messages/events around. I was wondering if there is a simple way for a function (in this case, an event's constructor) to obtain a reference to the object which called it? This is to ensure that a certain event that I am defining can only be dispatched by one specified class. My thinking is to check the caller of the constructor somehow, and throw an error if it is not of the correct type. I am open to suggestions of alternative approaches here, but I would ideally like to stick to using the Parsley 'MessageHandler' approach if at all possible. Thanks for reading guys..

  • Get the ID of user that like my page.

    - by jon
    Hello I would like to know if there is any API feature that can tell me which users liked my application page. I know that it is possible to check if a user is a fan of any given Page using page.isFan verification or to get the number of fans. But is it possible to get the fans' User ID? If so, is it possible to get that data ordered by the date they became fans of the page? For exemple usign FQL i can get the user ID of someone o like an facebook object like post or photo. http://developers.facebook.com/docs/reference/fql/like Can i do this for the people who liked my page?

  • How to use MOV instruction in ARM with an immediate number as the second operand

    - by Summer_More_More_Tea
    Hi everyone: I just begin to study ARM assembly language, and am not clear about how to use MOV to transfer an immediate number into a register. From both the ARM reference manual and my textbook, it's said that range of immediate number following MOV instruction is 0-255. But when I test on my own PC in ADS 1.2 IDE, instruction MOV R2, #0xFFFFFFFF performs well. Isn't number 0xFFFFFFFF out of range according to the specification? Hope someone can give me a hand. Regards.

  • After adding a UILabel to my view, how do I delete it?

    - by Travis
    I have added a UILabel to my view programmatically like this: myLabel = [[UILabel alloc] initWithFrame:CGRectMake(0.0f, 0.0f, 100.0f, 30.0f)]; myLabel.center = CGPointMake(160.0f, 120.0f); myLabel.backgroundColor = [UIColor clearColor]; myLabel.textColor = [UIColor whiteColor]; myLabel.font = [UIFont fontWithName:@"Helvetica" size: 18.0]; myLabel.textAlignment = UITextAlignmentCenter; myLabel.text = @"Hello"; [self.myView addSubview:myLabel]; To add a label to my view. What I can't seem to find out is once I'm done w/ the label (at a future point) how can I delete it from the view? [myLabel release] doesn't seem to work which I think makes sense because the view it's added to probably retained it's over reference. So what is the best practice?

  • The type or namespace name 'Oledb' does not exist in the namespace 'System.Data' error on Web Servic

Is there any way to prevent this?

  • Mathematica Plot3D does not produce a plot when graphing a user-defined function?

    - by pythonscript
    I'm writing a simple Mathematica implementation of the black-scholes model and using Plot3D to plot the pricing surface. However, when I run this code, no plot is produced. My call and put functions to produce correct values when run separately, but no plot is produced. Code: Clear[d1, d2, call, put, stockPrice, strikePrice, riskFreeRate, timeToExp, volatility] d1[stockPrice_, strikePrice_, riskFreeRate_, timeToExp_, volatility_] := (Log[stockPrice / strikePrice] + (riskFreeRate + 0.5*volatility^2)*timeToExp) / (volatility * Sqrt[timeToExp]) d2[stockPrice_, strikePrice_, riskFreeRate_, timeToExp_, volatility_] := d1[stockPrice, strikePrice, riskFreeRate, timeToExp, volatility] - volatility*Sqrt[timeToExp] call[stockPrice_, strikePrice_, riskFreeRate_, timeToExp_, volatility_] := stockPrice * CDF[NormalDistribution[0, 1], d1[stockPrice, strikePrice, riskFreeRate, timeToExp, volatility]] - strikePrice * Exp[-riskFreeRate*timeToExp] *CDF[NormalDistribution[0, 1], d2[stockPrice, strikePrice, riskFreeRate, timeToExp, volatility]] Plot3D[call[stockPrice, 500, 0.0030, timeToExp, 0.39], {stockPrice, 10, 1000}, {timetoExp, 0.0833333, 5}] Other plots, like this sample from the reference, do work. Plot3D[{x^2 + y^2, -x^2 - y^2}, {x, -2, 2}, {y, -2, 2}, RegionFunction -> Function[{x, y, z}, x^2 + y^2 <= 4], BoxRatios -> Automatic]

  • UI Terminology - Enabled vs. Active

    - by Pamela
    When designing a feature that can be accessed by different user levels, I'm wondering how the use of "enabled" versus "active" will work. If I'm an administrator, it means I have the ability to turn on and off a feature. Does this mean the feature is enabled for me or active? Once I turn this feature on, is it then enabled or active? Terminology is the pits. On the subject, does anyone know of a reference book or site dedicated to questions regarding standard terminology for UIs? Thanks a million!

  • How do I do this simple 301 redirect from index.htm to root?

    - by elliot100
    I've read various reference sites on redirection, and to be honest I understand very little. I currently have standard WordPress mod_rewrite redirect rules in my .htaccess: # BEGIN WordPress <IfModule mod_rewrite.c> RewriteEngine On RewriteBase / RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-d RewriteRule . /index.php [L] </IfModule> # END WordPress (1) Quite a few of my referrers go to a old URL http://www.example.com/index.htm, which gives them an error, and I want them to be redirected to http://www.example.com/ What do I need to do?

  • Does the order of readonly variable declarations guarantee the order in which the values are set?

    - by Jason Down
    Say I were to have a few readonly variables for filepaths, would I be able to guarantee the order in which the values are assigned based on the order of declaration? e.g. readonly string basepath = @"my\base\directory\location"; readonly string subpath1 = basepath + @"\abc\def"; readonly string subpath2 = basepath + @"\ghi\klm"; Is this a safe approach or is it possible that basepath may still be the default value for a string at the time subpath1 and subpath2 make a reference to the string? I realize I could probably guarantee the order by assigning the values in a constructor instead of at the time of declaration. However, I believe this approach wouldn't be possible if I needed to declare the variables inside of a static class (e.g. Program.cs for a console application, which has a static void Main() procedure instead of a constructor).

  • NHibernate Lazy="Extra"

    - by Adam Rackis
    Is there a good explanation out there on what exactly lazy="extra" is capable of? All the posts I've seen all just repeat the fact that it turns references to MyObject.ItsCollection.Count into select count(*) queries (assuming they're not loaded already). I'd like to know if it's capable of more robust things, like turning MyObject.ItsCollection.Any(o => o.Whatever == 5) into a SELECT ...EXISTS query. Section 18.1 of the docs only touches on it. I'm not an NH developer, so I can't really experiment with it and watch SQL Profiler without doing a bit of work getting everything set up; I'm just looking for some sort of reference describing what this feature is capable of. Thank you!

  • TStringList, Dynamic Array or Linked List in Delphi?

    I have a choice. I have an array of ordered strings that I need to store and access. It looks like I can choose between using: A TStringList A Dynamic Array of strings, and A Linked List of strings In what circumstances is each of these better than the others? Which is best for small lists (under 10 items)? Which is best for large lists (over 1000 items)? Which is best for huge lists (over 1,000,000 items)? Which is best tor minimize memory use? Which is best to minimize loading and/or access time? For reference, I am using Delphi 2009.
