  • Model Not Valid Even With No [Required] Attribute

    - by griegs
    I have a model which is validating as False even though I have no validation rules attached to it what so ever. So this is my model; public class QuickQuote { public Enumerations.AUSTRALIA_STATES state { get; set; } public Enumerations.FAMILY_TYPE familyType { get; set; } public Enumerations.CoverLevel hospitalCover { get; set; } public Enumerations.CoverLevel extrasCover { get; set; } public Enumerations.YesNo pregnancy { get; set; } } And in my controller I have; [AcceptVerbs(HttpVerbs.Post)] public ActionResult Index(IndexFormViewModel fvm) { if (!ModelState.IsValid) return View(fvm); The problem is that unless I put a value into each field it's validating as false even though it shouldn't care. Can anyone see what the problem is here?

  • this program runs but not correctly numbers arent right, i read numbers from a file and then when i

    - by user320950
    this is what i have to do: write a program that determines the grade dispersal for 100 students You are to read the exam scores into three arrays, one array for each exam. You must then calculate how many students scored A’s (90 or above), B’s (80 or above), C’s (70 or above), D’s (60 or above), and F’s (less than 60). Do this for each exam and write the distribution to the screen. // basic file operations #include <iostream> #include <fstream> using namespace std; int read_file_in_array(double exam[100][3]); double calculate_total(double exam1[], double exam2[], double exam3[]); // function that calcualates grades to see how many 90,80,70,60 //void display_totals(); double exam[100][3]; int main() { double go,go2,go3; double exam[100][3],exam1[100],exam2[100],exam3[100]; go=read_file_in_array(exam); go2=calculate_total(exam1,exam2,exam3); //go3=display_totals(); cout << go,go2,go3; return 0; } /* int display_totals() { int grade_total; grade_total=calculate_total(exam1,exam2,exam3); return 0; } */ double calculate_total(double exam1[],double exam2[],double exam3[]) { int calc_tot,above90=0, above80=0, above70=0, above60=0,i,j, fail=0; double exam[100][3]; calc_tot=read_file_in_array(exam); for(i=0;i<100;i++) { for (j=0; j<3; j++) { exam1[i]=exam[100][0]; exam2[i]=exam[100][1]; exam3[i]=exam[100][2]; if(exam[i][j] <=90 && exam[i][j] >=100) { above90++; { if(exam[i][j] <=80 && exam[i][j] >=89) { above80++; { if(exam[i][j] <=70 && exam[i][j] >=79) { above70++; { if(exam[i][j] <=60 && exam[i][j] >=69) { above60++; { if(exam[i][j] >=59) { fail++; } } } } } } } } } } } return 0; } int read_file_in_array(double exam[100][3]) { ifstream infile; int exam1[100]; int exam2[100]; int exam3[100]; infile.open("grades.txt");// file containing numbers in 3 columns if(infile.fail()) // checks to see if file opended { cout << "error" << endl; } int num, i=0,j=0; while(!infile.eof()) // reads file to end of line { for(i=0;i<100;i++) // array numbers less than 100 { for(j=0;j<3;j++) // while reading get 1st array or element infile >> exam[i][j]; infile >> exam[i][j]; infile >> exam[i][j]; cout << exam[i][j] << endl; { if (!

  • how to convert numbers to alpha numeric system with php

    - by Patrick
    Im not sure what this is called, which is why im having trouble searching for it. What im looking to do, is take numbers, and convert them to some alpha numeric base so that the number say 5000, wouldnt read 5000, but like G4u or something like that. The idea being to save space and also not make it obvious how many records there are in a given system. Im using php, so if there is something like this built into php even better, but even a name for this method would be helpful at this point Again, sorry for not being able to be more clear, im just not sure what this is called.

  • Even lighter than SQLite

    - by Richard Fabian
    I've been looking for a C++ SQL library implementation that is simple to hook in like SQLite, but faster and smaller. My projects are in games development and there's definitely a cutoff point between needing to pass the ACID test and wanting some extreme performance. I'm willing to move away from SQL string style queries, allowing it to be code driven, but I haven't found anything out there that provides SQL like flexibility while also preferring performance over the ACID test. I don't want to go reinventing the wheel, and the idea of implementing an SQL library on my own is quite daunting, even if it's only going to be simple subset of all the calls you could make. I need the basic commands (SELECT, MODIFY, DELETE, INSERT, with JOIN, and WHERE), not data operations (like sorting, min, max, count) and don't need the database to be atomic, or even enforce consistency (I can use a real SQL service while I'm testing and debugging).

  • jQuery: I need something like ':visible' that works even if the parent is display=none

    - by Master Morality
    I have a list where elements are hidden for multiple reasons, each corresponding to a css class i.e: <style> .filteredOut { display: none; } .somethingElse { display : none; } ... </style> I want to apply alternating css classes via .filter(':even').addClass('even') but only to classes that are visible. The problem is that the parent is hidden when this happens so .filter(':visible') returns 0 elements. I need something like .filter(':visibileEventIfParentIsNot') Further more, I'd rather not have to call a function with this in it every time I call a function that changes what's visible in a list. This may be a pipe dream, but is there a way to do this ala live() or something similar? I'm open to off the wall ideas.

  • Is there a way to force JUnit to fail on ANY unchecked exception, even if swallowed

    - by Uri
    I am using JUnit to write some higher level tests for legacy code that does not have unit tests. Much of this code "swallows" a variety of unchecked exceptions like NullPointerExceptions (e.g., by just printing stack trace and returning null). Therefore the unit test can pass even through there is a cascade of disasters at various points in the lower level code. Is there any way to have a test fail on the first unchecked exception even if they are swallowed? The only alternative I can think of is to write a custom JUnit wrapper that redirects System.err and then analyzes the output for exceptions.

  • Firefox running infinitely even after condition met in jquery function

    - by Kyle
    The following function is called with setTimeout(function () { get_progress(fileID,fileName)},8000); upon a form submit. The purpose of the function is to get read_file.php to read a txt file that stores the file upload status from a form (in percentage). Upon reaching 80%, my Firefox seems to run infinitely even when HEAD returns an error. Am I have too many recursions or have I used a wrong condition that's causing get_progress to run repeatedly even when filename does not exist in the folder ? function get_progress( fileID, filename) { $.ajax({ url: filename, type: 'HEAD', success: function() { $.ajax({ type: 'POST', url: 'read_file.php', data: 'filename=' +filename, success: function(html) { document.getElementById(fileID).innerHTML = html + ' <img src="images/loading.gif" />' setInterval(function() {get_progress(fileID,filename)},4000); } }); } });}

  • Explanation of SendMessage message numbers? (C#, Winforms)

    - by John
    I've successfully used the Windows SendMessage method to help me do various things in my text editor, but each time I am just copying and pasting code suggested by others, and I don't really know what it means. There is always a cryptic message number that is a parameter. How do I know what these code numbers mean so that I can actually understand what is happening and (hopefully) be a little more self-sufficient in the future? Thanks. Recent example: using System.Runtime.InteropServices; [DllImport("user32.dll")] static extern int SendMessage(IntPtr hWnd, uint wMsg,UIntPtr wParam, IntPtr lParam); SendMessage(myRichTextBox.Handle, (uint)0x00B6, (UIntPtr)0, (IntPtr)(-1));

  • help with number calculation algorithm [hw]

    - by sa125
    Hi - I'm working on a hw problem that asks me this: given a finite set of numbers, and a target number, find if the set can be used to calculate the target number using basic math operations (add, sub, mult, div) and using each number in the set exactly once (so I need to exhaust the set). This has to be done with recursion. So, for example, if I have the set {1, 2, 3, 4} and target 10, then I could get to it by using ((3 * 4) - 2)/1 = 10. I'm trying to phrase the algorithm in pseudo-code, but so far haven't gotten too far. I'm thinking graphs are the way to go, but would definitely appreciate help on this. thanks.

  • *Client* scalability for large numbers of remote web service calls

    - by Yuriy
    Hey Guys, I was wondering if you could share best practices and common mistakes when it comes to making large numbers of time-sensitive web service calls. In my case, I have a SOAP and an XML-RPC based web service to which I'm constantly making calls. I predict that this will soon become an issue as the number of calls per second will grow. On a higher level, I was thinking of batching those calls and submitting those to the web services every 100 ms. Could you share what else works? On a lower level side of the things, I use Apache Xml-Rpc client and standard javax.xml.soap.* packages for my client implementations. Are you aware of any client scalability related tricks/tips/warnings with these packages? Thanks in advance Yuriy

  • Get signal names from numbers in Python

    - by Brian M. Hunt
    Is there a way to map a signal number (e.g. signal.SIGINT) to its respective name (i.e. "SIGINT")? I'd like to be able to print the name of a signal in the log when I receive it, however I cannot find a map from signal numbers to names in Python, i.e. import signal def signal_handler(signum, frame): logging.debug("Received signal (%s)" % sig_names[signum]) signal.signal(signal.SIGINT, signal_handler) For some dictionary sig_names, so when the process receives SIGINT it prints: Received signal (SIGINT) Thank you.

    Hi, I'm using an sql to replace credit card numbers with xxxx and finding that REGEX_REPLACE does not consistently replace everything. Below is the SET command i'm using on the SQL SET COMMENTS_LONG = REGEXP_REPLACE (COMMENTS_LONG,'\D[1-6]\d{3}.\d{4}.\d{4}.\d{3}(\d{1}.\d{3})?|\D[1-6]\d{12,15}|\D[1-6]\d{3}.\d{3}.?\d{3}.\d{5}', ' XXXXXXXXXXXXXXXX') Before Elizabeth aclled to change address.5430-6000-2111-1931 A After Elizabeth aclled to change address XXXXXXXXXXXXXXXX1 A I tried increasing the number of X but result is the same. I also find that i have to put a space in front of the first X as it appears to move 1 char to the left.

  • Order by text and then by number

    - by Chaim Chaikin
    I have data like: Audio 1 File 10 Audio 2 Audio 3 File 11 Audio 13 Audio 22 File 20 Test 22 Audio 10 File 1 File 2 I need it order first by the text (i.e. Audio, File, Test) and then by number (1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22 etc.) The problem is that sorting it returns something like this: Audio 1 Audio 10 Audio 13 Audio 2 Audio 22 Audio 3 File 1 File 10 File 11 File 2 File 20 Test 22 While the result I want is: Audio 1 Audio 2 Audio 3 Audio 10 Audio 13 Audio 22 File 1 File 2 File 10 File 11 File 20 Test 22 If they were just numbers (i.e. without the audio, file, test) then I could just sort numerically. However, how can I sort here first by text and then by number.

  • PHP Form Validation Regular Expression, no symbols or numbers

    - by MrEnder
    Ok I am trying to get the users First Name the form gets their name perfectly fine and posts it into a variable. Now I am trying to do error checking else if(!preg_match("/^[\w-]+$/", $firstNameSignup)) { $firstNameSignupError = "Your first name cannot contain numbers or symbols, you entered " . $firstNameSignup; $firstNameSignup = ""; } I tried the above code and it does not like me but my if statement if(!isset($firstNameSignup) || $firstNameSignup == "") { $firstNameSignupError = "You must enter your first name"; } works fine so I know that the error is in that else if statement... most likely in my regular expression any help??? I'm totally at a loss (really new to PHP and regular expressions) Thanks Shelby

  • GWT's JSONParser producing incorrect values for numbers.

    - by WesleyJohnson
    I'm work with GWT and parsing a JSON result from an ASP.NET webservice method that returns a DataTable. I can parse the result into a JSONvalue/JSONObject just fine. The issue I'm having is that one my columns in a DECIMAL(20, 0) and the values that are getting parsed into JSON aren't exact. To demonstrate w/o the need for a WS call, in GWT I threw this together: String jsonString = "{value:4768428229311981600}"; JSONObject jsonObject = JSONParser.parse( jsonString ).isObject(); Window.alert( jsonObject.toString() ); This in turn alerts: {"value":4768428229311982000} I'm under the understanding that GWT's JSONParser is just using eval() to do the parsing, so is this some sort of number/precision issue with JavaScript that I've never been aware of. I'll admit I don't work with numbers that much in JavaScript and I might be able to work around this by changing the .NET WebService to return this column as string, but I'd really rather not do that. Thanks for any help.

  • split a string based on pattern in java - capital letters and numbers

    - by rookie
    Hi all I have the following string "3/4Ton". I want to split it as -- word[1] = 3/4 and word[2] = Ton. Right now my piece of code looks like this:- Pattern p = Pattern.compile("[A-Z]{1}[a-z]+"); Matcher m = p.matcher(line); while(m.find()){ System.out.println("The word --> "+m.group()); } It carries out the needed task of splitting the string based on capital letters like:- String = MachineryInput word[1] = Machinery , word[2] = Input The only problem is it does not preserve, numbers or abbreviations or sequences of capital letters which are not meant to be separate words. Could some one help me out with my regular expression coding problem. Thanks in advance...

  • Odd results when searching for numbers using IXSSO.Query

    - by Vic
    Hi, from classic asp on Windows 2008, using an IXSSO.Query, when searching for a string of numbers, for example 10000000001, I receive results that also include variations to this, like 10000000002 10000000003 and so on. If I change the first digit so the search string is 20000000001 I dont get anything. If I keep moving the last digit from my first example to the left, I keep getting hits until I reach the half way point when I get no results! So in other words 10000020000 will return results like in the first example but 10000200000 does not. This all sounds like to me that its doing a match on the first 6 characters and it ignores the rest... Here is relevant parts of the Set oQuery = Server.CreateObject("IXSSO.Query") oQuery.Catalog = SEARCH_CATALOG oQuery.Query = "@all " & searchstr Set oRS = oQuery.CreateRecordset("nonsequential") Anyone got any ideas and/or suggestions? Thanks, Vic.

  • is there a such thing as a randomly accessible pseudo-random number generator? (preferably open-sour

    - by lucid
    first off, is there a such thing as a random access random number generator, where you could not only sequentially generate random numbers as we're all used to, assuming rand100() always generates a value from 0-100: for (int i=0;i<5;i++) print rand100() output: 14 75 36 22 67 but also randomly access any random value like: rand100(0) would output 14 as long as you didn't change the seed rand100(3) would always output 22 rand100(4) would always output 67 and so on... I've actually found an open-source generator algorithm that does this, but you cannot change the seed. I know that pseudorandomness is a complex field; I wouldn't know how to alter it to add that functionality. Is there a seedable random access random number generator, preferably open source? or is there a better term for this I can google for more information? if not, part 2 of my question would be, is there any reliably random open source conventional seedable pseudorandom number generator so I could port it to multiple platforms/languages while retaining a consistent sequence of values for each platform for any given seed?

  • Rounding Decimals to whole numbers

    - by USDblades
    I was looking around and could not find exactly what I was looking for. I want to round all my numbers up to the whole number. Example: 5.9 would be 6 5.5 would be 6 5.1 would be 6 5.000001122 would be 6 5.0 would be 5 I was thinking if I put them into ints that would get rid of the decimal but it did not look right as the decimals were just dropping off. Am I correct here? So I thought about just doing that then adding 1 to the final result which would fix about 99% of the problem but if my result is 5 I do not want to add 1 to it. How would I go about fixing this issue I have?

  • Reading a triangle of numbers into a 2d array of ints in Python

    - by Gabriel Silk
    I want to read a triangle of integer values from a file into a 2D array of ints using Python. The numbers would look like this: 75 95 64 17 47 82 18 35 87 10 20 04 82 47 65 ... The code I have so far is as follows: f = open('problem18.input', 'r') arr = [] for i in range(0, 15): arr.append([]) str = f.readline() a = str.split(' ') for tok in a: arr[i].append(int(tok[:2])) print arr I have a feeling this could be done in a tighter, more Pythonesque way. How would you do it?

  • Ruby on Rails - Currency : commas causing an issue.

    - by easement
    Looking on SO, I see that the preferred way to currency using RoR is using decimal(8,2) and to output them using number_to_currency(); I can get my numbers out of the DB, but I'm having issues on getting them in. Inside my update action I have the following line: if @non_labor_expense.update_attributes(params[:non_labor_expense]) puts YAML::dump(params) The dump of params shows the correct value. xx,yyy.zz , but what gets stored in the DB is only xx.00 What do I need to do in order to take into account that there may be commas and a user may not enter .zz (the cents). Some regex and for comma? how would you handle the decimal if it were .2 versus .20 . There has to be a builtin or at least a better way. My Migration (I don't know if this helps): class ChangeExpenseToDec < ActiveRecord::Migration def self.up change_column :non_labor_expenses, :amount, :decimal, :precision => 8, :scale => 2 end def self.down change_column :non_labor_expenses, :amount, :integer end end
