  • Can I perform some processing on the POST data before ASP.NET MVC UpdateModel happens?

    - by Domenic
    I would like to strip out non-numeric elements from the POST data before using UpdateModel to update the copy in the database. Is there a way to do this? // TODO: it appears I don't even use the parameter given at all, and all the magic // happens via UpdateModel and the "controller's current value provider"? [HttpPost] public ActionResult Index([Bind(Include="X1, X2")] Team model) // TODO: stupid magic strings { if (this.ModelState.IsValid) { TeamContainer context = new TeamContainer(); Team thisTeam = context.Teams.Single(t => t.TeamId == this.CurrentTeamId); // TODO HERE: apply StripWhitespace() to the data before using UpdateModel. // The data is currently somewhere in the "current value provider"? this.UpdateModel(thisTeam); context.SaveChanges(); this.RedirectToAction(c => c.Index()); } else { this.ModelState.AddModelError("", "Please enter two valid Xs."); } // If we got this far, something failed; redisplay the form. return this.View(model); } Sorry for the terseness, up all night working on this; hopefully my question is clear enough? Also sorry since this is kind of a newbie question that I might be able to get with a few hours of documentation-trawling, but I'm time-pressured... bleh.

  • Ruby - encrypted_strings

    - by Tom Andersen
    A bit of a Ruby newbie here - should be an easy question: I want to use the encrypted_strings gem to create a password encrypted string: (from http://rdoc.info/projects/pluginaweek/encrypted_strings) Question is: Everything works fine, but how come I don't need the password to decrypt the string? Say I want to store the string somewhere for a while,like the session. Is the password also stored with it? (which would seem very strange?). And no, I'm not planning on using 'secret-key' or any similar hack as a password. I am planning on dynamically generating a class variable @@password using a uuid, which I don't store other than in memory, and can change from one running of the program to the next. Symmetric: >> password = 'shhhh' => "shhhh" >> crypted_password = password.encrypt(:symmetric, :password => 'secret_key') => "qSg8vOo6QfU=\n" >> crypted_password.class => String >> crypted_password == 'shhhh' => true >> password = crypted_password.decrypt => "shhhh"

  • making arrays from tab-delimited text file column

    - by absolutenewbie
    I was wondering if anyone could help a desperate newbie with perl with the following question. I've been trying all day but with my perl book at work, I can't seem to anything relevant in google...or maybe am genuinely stupid with this. I have a file that looks something like the following: Bob April Bob April Bob March Mary August Robin December Robin April The output file I'm after is: Bob April April March Mary August Robin December April So that it lists each month in the order that it appears for each person. I tried making it into a hash but of course it wouldn't let me have duplicates so I thought I would like to have arrays for each name (in this example, Bob, Mary and Robin). I'm afraid to upload the code I've been trying to tweak because I know it'll be horribly wrong. I think I need to define(?) the array. Would this be correct? Any help would be greatly appreciated and I promise I will be studying more about perl in the meantime. Thank you for your time, patience and help. #!/usr/bin/perl -w while (<>) { chomp; if (defined $old_name) { $name=$1; $month=$2; if ($name eq $old_name) { $array{$month}++; } else { print "$old_name"; foreach (@array) { push (@array, $month); print "\t@array"; } print "\n"; @array=(); $array{$month}++; } } else { $name=$1; $month=$2; $array{month}++; } $old_name=$name; } print "$old_name"; foreach (@array) { push (@array, $month); print "\t@array"; } print "\n";

  • C# Delegate under the hood question.

    - by Ted
    Hi Guys I was doing some digging around into delegate variance after reading the following tquestion in SO. "delegate-createdelegate-and-generics-error-binding-to-target-method" (sorry not allowed to post more than one hyperlink as a newbie here!) I found a very nice bit of code from Barry kelly at https://www.blogger.com/comment.g?blogID=8184237816669520763&postID=2109708553230166434 Here it is (in a sugared-up form :-) using System; namespace ConsoleApplication4 { internal class Base { } internal class Derived : Base { } internal delegate void baseClassDelegate(Base b); internal delegate void derivedClassDelegate(Derived d); internal class App { private static void Foo1(Base b) { Console.WriteLine("Foo 1"); } private static void Foo2(Derived b) { Console.WriteLine("Foo 2"); } private static T CastDelegate<T>(Delegate src) where T : class { return (T) (object) Delegate.CreateDelegate( typeof (T), src.Target, src.Method, true); // throw on fail } private static void Main() { baseClassDelegate a = Foo1; // works fine derivedClassDelegate b = Foo2; // works fine b = a.Invoke; // the easy way to assign delegate using variance, adds layer of indirection though b(new Derived()); b = CastDelegate<derivedClassDelegate>(a); // the hard way, avoids indirection b(new Derived()); } } } I understand all of it except this one (what looks very simple) line. b = a.Invoke; // the easy way to assign delegate using variance, adds layer of indirection though Can anyone tell me: how it is possible to call invoke without passing the param required by the static function. When is going on under the hood when you assign the return value from calling invoke What does Barry mean by extra indirection (in his comment)

  • SubViewTwoController undeclared (first use in this function) (obj-c)

    - by benny
    Ahoy hoy everyone :) Here is a list of links. You will need it when reading the post. I am a newbie to Objective-C and try to learn it for iPhone-App-Development. I used the tutorial linked in the link list to create a standard app with a simple basic Navigation. This app contains a "RootView" that is displayed at startup. The startup screen itself contains three elements wich all link to SubViewOne. I have got it to work this far. So what i want to change is to make the second element link to SubViewTwo. When i "Build and Go" it, i get the following errors: RootViewController.m: SubViewTwoController *subViewTwoController = [[SubViewTwoController alloc] init]; // SubViewTwoController undeclared (first use in this function) and in SubViewTwoController.m [super didReceiveMemoryWarning]; // Releases the view if it doesn't have a superview no superclass declared in @interface for ´SubViewTwoController´ and the same thing after - (void)dealloc { [super dealloc]; I think you will also need the header files, so here they are! RootViewController.h #import <UIKit/UIKit.h> @interface RootViewController : UITableViewController { IBOutlet NSMutableArray *views; } @property (nonatomic, retain) IBOutlet NSMutableArray *views; @end SubViewOneController.h #import <UIKit/UIKit.h> @interface SubViewOneController : UIViewController { IBOutlet UILabel *label; IBOutlet UIButton *button; } @property (retain,nonatomic) IBOutlet UILabel *label; @property (retain,nonatomic) IBOutlet UIButton *button; - (IBAction) OnButtonClick:(id) sender; @end and SubViewTwoController.h #import <UIKit/UIKit.h> @interface SubViewTwo : UIViewController { IBOutlet NSMutableArray *views; } @end I would be really great if you would leave your ideas with a short explanation. Thanks a lot in advance! benny

    - by CVertex
    I'm a newbie to python and the app engine. I have this code that sends an email based on request params after some auth logic. in my Unit tests (i'm using GAEUnit), how do I confirm an email with specific contents were sent? - i.e. how do I mock the emailer with a fake emailer to verify send was called? class EmailHandler(webapp.RequestHandler): def bad_input(self): self.response.set_status(400) self.response.headers['Content-Type'] = 'text/plain' self.response.out.write("<html><body>bad input </body></html>") def get(self): to_addr = self.request.get("to") subj = self.request.get("subject") msg = self.request.get("body") if not mail.is_email_valid(to_addr): # Return an error message... # self.bad_input() pass # authenticate here message = mail.EmailMessage() message.sender = "[email protected]" message.to = to_addr message.subject = subj message.body = msg message.send() self.response.headers['Content-Type'] = 'text/plain' self.response.out.write("<html><body>success!</body></html>") And the unit tests, import unittest from webtest import TestApp from google.appengine.ext import webapp from email import EmailHandler class SendingEmails(unittest.TestCase): def setUp(self): self.application = webapp.WSGIApplication([('/', EmailHandler)], debug=True) def test_success(self): app = TestApp(self.application) response = app.get('http://localhost:8080/[email protected]&body=blah_blah_blah&subject=mySubject') self.assertEqual('200 OK', response.status) self.assertTrue('success' in response) # somehow, assert email was sent

  • Delphi - working with dll's for beginners

    - by doubleu
    Hi there, I'm a total newbie regarding to DLL. And I don't need to creat them I just need to use one. I've read some tutorials, but they weren't as helpful as I hoped. Here's the way I started: I've downloaded the SDK which I need to use (ESTOS Tapi Server). I read in the docs and spotted out the DLL which I need to use, which is the ENetSN.dll, and so I registered it. Next I've used the Dependency Walker to take a look at the DLL - and I was wondering because there are only these functions: DllCanUnloadNow, DllGetClassObject, DllRegisterServer and DllUnregisterServer, and these are not the functions mentioned in the docs. I think I have to call DllGetClassObject to get an object out of the DLL with which I can start to work. Unfortunately the tutorials I found doesn't mentioned how this is done (or I didn't understood it). There are also 3 exmaples delivered for VB and C++, but I wasn't able to 'translate' them into delphi. If somebody knows a tutorial where this is explained or could give me a pointer to the right direcetion, I would be very thankful .

  • Jquery ajax auto complete problem

    - by squeaker
    Hi all, I'm having newbie problems resolving an ajax autocomplete script if anyone would like to offer advise? In my form i wish for users to select an event type (drop down box) which on selecting then displays a text box. This text box then offers a user the ability to autocomplete as they start typing, the options having been generated through AJAX depending on the event type selected. I'm using a mix of http://pengoworks.com/workshop/jquery/autocomplete.htm - to carry out the autocomplete and some basic jquery to identify the value of the event type selected. The problem I have within the code below is to pass the selected event type value, set as the variable 'caturl', into the 'extraParams:{cat:4}' replacing the 4 with the event type dynamically selected. Any help would be greatly received. $('#select').change(function() { $('.eventtype').hide(); $('#eventtype' + $(this).find('option:selected').attr('id')).show(); caturl = $('#select :selected').val(); }); $("#CityAjax").autocomplete( 'caturl.php', { delay:10, minChars:2, matchSubset:1, matchContains:1, cacheLength:10, onItemSelect:selectItem, onFindValue:findValue, formatItem:formatItem, extraParams:{cat:4}, autoFill:true });

  • Nginx rewrite for link shortener and Wordpress

    - by detusueno
    I'm a complete newbie to Nginx, so much so that I followed a online guide to do most of my server setup. I'm trying to learn but I'm still a ways away from understanding it all. So what I'm trying to create is a link shortener that redirects (example.com/x) to (example.com/short.php?id=x). Keep in mind that I'm also running a Wordpress blog on the same domain and plan on using the redirects/shortening for external links. The guide has so far had me add the following rewrites to enable Wordpress pretty URLs: # WordPress pretty URLs: (as per dominiek.com) if (-f $request_filename) { break; } if (-d $request_filename) { break; } rewrite ^(.+)$ /index.php?q=$1 last; # Enable nice permalinks for WordPress: (as per Yawn.it) error_page 404 = //index.php?q=$uri; And if it matters any, it was saved at (/usr/local/nginx/conf/wordpress_params.regular). Additionally, my Wordpress link structure adds "news" to all internal links (example.com/news/post-blah, example.com/news/category, ect.). What's the best way to tackle this setup?

  • How to call stored proc from ASP.Net MVC stack via the ORM & return them in json?

    - by melaos
    Hi guys, i'm a total newbie with asp.net mvc and here's my jam: i have a 3 level list box which selection on box A shows options on box B and selection on box B will show the options for box C. I'm trying to do the whole thing in asp.net MVC and what i see is that the nerd dinner tutorial uses the ORM method. so i created a dbml to the database and drag the stored proc inside. i create a datacontext object but i don't quite know how to connect the result from the stored proce which should be multiple rows of data and make it into a json. so i can keep all the json data inside the html page and using jquery i could make the selection process faster. i don't expect the data inside the three boxes to change so often thus i think this method should be quite viable. Questions: So how do i get the stored proc part to return the data as json? i've noticed some tutorial online that the json return result part is at the controller and not at the model end. Why is that?

  • PHP Error handling in WordPress plugin

    - by AaronM
    I am a newbie to both PHP and Wordpress (but do ok in C#), and am struggling to understand the error handling in a custom plugin I am attempting to write. The basics of the plugin is to query an exsiting MSSQL database (note its not the standard MYSQL db...) and return the rows back to the screen. This was working well, but the hosting provider has taken my database offline, which led me to the error handling problem (which I thought was ok). The following code is failing to connect to the database (as expected), but puts an error onto the screen and stops the page processing. It does not even output the 'or die' error text. QUESTION: How can I just output a simple "Cant load data" message, and continue on normally? function generateData() { global $post; if ("$post->post_title" == "Home") { try { $myServer = "<servername>"; $myUser = "<username>"; $myPass = "<password>"; $myDB = "<dbName>"; //connection to the database $dbhandle = mssql_connect($myServer, $myUser, $myPass) or die("Couldn't open database $myDB"); //... query processing here... } catch (Exception $e) { echo "Cannot load data<br />"; } } return $content; } Error being generated: (line 31 is $dbhandle = mssql_connect...) Warning: mssql_connect() [function.mssql-connect]: Unable to connect to server: <servername> in <file path> on line 31 Fatal error: Maximum execution time of 30 seconds exceeded in <file path> on line 31

  • Alternative to sql NOT IN?

    - by Alex
    Hi, I am trying to make a materialized view in Oracle (I am a newbie, btw). For some reason, it doesn't like the presence of sub-query in it. I've been trying to use LEFT OUTER JOIN instead, but it's returning different data set now. Put simply, here's the code I'm trying to modify: SELECT * FROM table1 ros, table2 bal, table3 flx WHERE flx.name = 'XXX' AND flx.value = bal.value AND NVL (ros.ret, 'D') = Nvl (flx.attr16, 'D') AND ros.value = bal.segment3 AND ros.type IN ( 'AL', 'AS', 'PL' ) AND bal.period = 13 AND bal.code NOT IN (SELECT bal1.code FROM table2 bal1 WHERE bal1.value = flx.value AND bal1.segment3 = ros.value AND bal1.flag = bal.flag AND bal1.period = 12 AND bal1.year = bal.year) And here's one of my attempt: SELECT * FROM table1 ros, table2 bal, table3 flx LEFT OUTER JOIN table2 bal1 ON bal.code = bal1.code WHERE bal1.code is null AND bal1.segment3 = ros.value AND bal.segment3 = ros.value AND bal1.flag = bal.flag AND bal1.year = bal.year AND flx.name = 'XXX' AND flx.value = bal.value AND bal1.value = flx.value AND bal1.period_num = 12 AND NVL (ros.type, 'D') = NVL (flx.attr16, 'D') AND ros.value = bal.segment3 AND ros.type IN ( 'AL', 'AS', 'PL' ) AND bal.period = 13; This drives me nuts! Thanks in advance for the help :)

  • How to more effectively debug PHP code in the vein JavaScript with Firebug or XCode?

    - by racl101
    Hi everyone, I'm kind of a newbie with PHP so please bear with me. I would like to know if there was an effective way of debugging PHP code so that I don't have to have debugging messages display on the browser. For example, I find var_dump and print_r functions to be excellent for debugging variables, function calls and arrays respectively. The problem is I have been asked to debug code on a live site (no dev site, I know it is a horrible practice but this is not my project from the start.) So I would like to know what core function or php library or whatever else it is that I could use to log debugging calls in to log that I can check so I don't have to send debugging calls to the browser on a live site? I like the way you can use the console.log function in JavaScript code and check it in Firebug or the Webkit Console and I also like like the console window in Xcode and I was wondering if there was some similar tool for PHP debugging. Any extra info and pearls of wisdom would be greatly appreciated. Thanks, racl101.

  • Error when calling SQL SP via LINQ

    Newbie problem: I have a SQL SP with ten parameters (eight input, two output) but when I attempt to call it via LINQ from code I get the following error message: "The best overloaded method match for 'DataClassesDataContext.ST_CR_CREATE_CASE_BASIS(string, string, string, string, System.DateTime?, string, string, string, ref int?, ref int?)' has some invalid arguments". The params with ? appear to be unrecognized, but I'm baffled: the data types match the SQL types, the number of parameters match, the other parmeters don't exhibit the same behaviour. Can anyone tell me what's going on? Thanks in advance. -- SQL SP: create procedure ST_CR_CREATE_CASE_BASIS @p_Pers_No nvarchar (50), @p_Subject nvarchar (255), @p_RQ_XML nvarchar(max), @p_RQ_XSL nvarchar(max), @p_Date_Submit smalldatetime, @p_User_ID_Submit nvarchar (255), @p_RQ_Status nvarchar (50), @p_User_ID_OnBehalf nvarchar (255), @p_Case_Number int output, @p_RQ_ID int output as begin -- ... etc.; the SP works fine when called from SSMS The code-behind proc from the aspx page looks like this: protected void cmdSubmit_Click(object sender, EventArgs e) { using (DataClassesDataContext vDataCont = new DataClassesDataContext()) { Int32 vNewCaseNr; Int32 vNewReqNr; DateTime vNow = System.DateTime.Now; vDataCont.ST_CR_CREATE_CASE_BASIS("101", "Test Subject Late Wed", null, null, vNow , "101", "1", "101", ref vNewCaseNr, vNewReqNr); } }

  • Need some ignition for learning Embedded Systems

    - by Rahul
    I'm very much interested in building applications for Embedded Devices. I'm in my 3rd year Electrical Engineering and I'm passionate about coding, algorithms, Linux OS, etc. And also by Googling I found out that Linux OS is one of the best OSes for Embedded devices(may be/may not be). I want to work for companies which work on mobile applications. I'm a newbie/naive to this domain & my skills include C/C++ & MySQL. I need help to get started in the domain of Embedded Systems; like how/where to start off, Hardware prerequisites, necessary programming skills, also what kind of Embedded Applications etc. I've heard of ARM, firmware, PIC Micorcontrollers; but I don't know anything & just need proper introduction about them. Thanx. P.S: I'm currently reading Bjarne Struotsup's lecture in C++ at Texas A&M University, and one chapter in it describes about Embedded Systems Programming.

  • Is their a definitive list for the differences between the current version of SQL Azure and SQL Serv

    - by Aim Kai
    I am a relative newbie when it comes to SQL Azure!! I was wondering if there was a definitive list somewhere regarding what is and is not supported by SQL Azure in regards to SQL Server 2008? I have had a look through google but I've noticed some of the blog posts are missing things which I have found through my own testing: For example, quite a lot is summarised in this blog entry http://www.keepitsimpleandfast.com/2009/12/main-differences-between-sql-azure-and.html Common Language Runtime (CLR) Database file placement Database mirroring Distributed queries Distributed transactions Filegroup management Global temporary tables Spatial data and indexes SQL Server configuration options SQL Server Service Broker System tables Trace Flags which is a repeat of the MSDN page http://msdn.microsoft.com/en-us/library/ff394115.aspx I've noticed from my own testing that the following seem to have issues when migrating from SQL Server 2008 to the Azure: XML Types (the msdn does mention large custom types - I guess it may include this?? even if the data schema is really small?) Multi-part views I've been using SQL Azure Migration Wizard v3.1.8 to migrate local databases into the cloud. I was wondering if anyone could point to a list or give me any information till when these features are likely to be included in SQL Azure.

  • Append to a webpage in javascript

    - by Lily
    What I want to do is that: a webpage with continuously updating content. (In my case is updating every 2s) New content is appended to the old one instead of overwriting the old one. Here is the code I have: var msg_list = new Array( "<message>Hello, Clare</message>", "<message>Hello,Lily</message>", "<message>Hello, Kevin</message>", "<message>Hello, Bill</message>" ); var number = 0; function send_msg() { document.write(number + " " + msg_list[number%4]+'<br/>'); number = number + 1; } var my_interval = setInterval('send_msg()', 2000); However, in both IE and Firefox, only one line is printed out, and the page will not be updated anymore. Interestingly in Chrome, the lines being printed out continuously, which is what I am looking for. I know that document.write() is called when the page is loaded according to this. So it's definitely not the way to update the webpage continuously. What will be the best way to achieve what I want to do? Totally newbie in Javascript. Thank you. Lily

  • Strange Problem with Webservice and IIS

    - by Rene
    Hello there, I have a Problem which confuses me a little bit, resp. where I don't have any Idea about what it could be. The System I'm using is Windows Vista, IIS 7.0, VS2008, Windows Software Factory, Entity Framework, WCF. The Binding for all Webservices is wshttpbinding. I'm using a Webservice hosted in IIS. This Webservice uses/calls another Webservice (also installed in the IIS). If I use a client calling the first Webservice (which calls the second Webservice) it works fine for about 4-10 Times. And then (it is repeatable to get this Problem, but sometimes it happens after 4, sometimes after 10 Time, but it always will happen), the Service and the IIS gets stuck. Stuck means, that this Webservice isn't callable anymore and generates an timeout after 1 minute. Even increasing Timeout doesn't change anything. If i try to restart the IIS I get an timeout error. So the IIS is also "stuck" (it is not really stuck, but I can't restart it). Only if I kill the w3wp.exe IIS is restartable and the Webservice will work again (until i again call this service several times). The logfiles (i'm no expert in things like logging or where to find/enable such logs, so to say : i'm a newbie) like http-logging, Event Viewer or WCF-Message Logging don't show any hints upon the source of the problem. I don't have this problem when I'm using a Webservice which doesn't call another Service. Calling a Webservice is done by Service Reference (I'm using no Proxy-Classes), but I think this should be no Problem. I have no idea of what is happening, nor how to solve this Problem.

  • Nested asynchronous calls do not seem to execute as expected

    - by Kristof Van Landschoot
    While trying out jQuery, I have a question that is probably a newbie mistake, but I cannot seem to find the solution. This is the code: $.get("index.html", function() { var i = 0; for (; i < 3; i++) { var lDiv = document.createElement('div'); lDiv.id = 'body-' + i; document.getElementById('body').appendChild(lDiv); $.get('index.html', function(data) { lDiv.innerHTML = "<p>Hello World " + i + "</p>"; }); } }); The output seems to be <div id='body-0'></div> <div id='body-1'></div> <div id='body-2'> <p>Hello World 3</p> </div> I expected the lDiv.innerHTML= code to be executed for each i, but apparently it is only executed for the last i? What am I overlooking?

  • C & MinGW: Hello World gives me the error "programm too big to fit in memory"

    - by user1692088
    I'm new here. Here's my problem: I installed MinGW on my Windows 7 Home Premium 32-bit Netbook with Intel Atom CPU N550, 1.50GHz and 2GB RAM. Now I made a file named hello.h and tried to compile it via CMD with the following command: "gcc c:\workspace\c\helloworld\hello.h -o out.exe" It compiles with no error, but when I try to run out.exe, it gives me following error: "program too big to fit in memory" Things I have checked: I have added "C:\MinGW\bin" to the Windows PATH Variable I have googled for about one hour, but ever since I'm a newbie, I can't really figure out what the problem is. I have compiled the same code on my 64-bit machine, compiles perfectly, but cannot be run due to 64-bit <- 16-bit problematic. I'd really appreciate, if someone could figure out, what the problem is. Btw, here's my hello.h: #include <stdio.h> int main(void){ printf("Hello, World\n"); } ... That's it. Thanks for your replies. Cheers, Boris
