  • Why does cloning the django inline formsets result to forms with similar ids and names?

    - by user1289167
    In my project I use django inline formsets. I got the jquery to clone the formsets but unfortunately the cloned forms have the same names and ids and so data entered in the last one overwrites the data from the first form. What could I be doing wrong? Here is the script: <script type="text/javascript">> function cloneMore(selector, type) { var newElement = $(selector).clone(true); var total = $('#id_' + type + '-TOTAL_FORMS').val(); newElement.find(':input').each(function() { var name = $(this).attr('name').replace('-' + (total-1) + '-','-' + total + '-'); var id = 'id_' + name; $(this).attr({'name': name, 'id': id}).val('').removeAttr('checked'); }); newElement.find('label').each(function() { var newFor = $(this).attr('for').replace('-' + (total-1) + '-','-' + total + '-'); $(this).attr('for', newFor); }); total++; $('#id_' + type + '-TOTAL_FORMS').val(total); $(selector).after(newElement); } </script>

  • Manipulate method functionality call

    - by danrichardson
    Hello, is it possibly in c# to have some sort of base class functionality which is manipulated slightly based on the class. For instance say i have the following code (which will quite obviously not compile it's meant to only be for demonstrative purposes) class BaseFunctionality { public virtual bool adminCall public static string MethodName(int id, string parameter) { if (adminCall) return dbcall.Execute(); else return dbcall.ExecuteMe(); } } class Admin : BaseFunctionality { override bool adminCall = true; } class Front : BaseFunctionality { override bool adminCall = false; } Now what i would like to be able to do is; string AdminCall = Admin.MethodName(1, "foo"); string FrontCall = Front.MethodName(2, "bar"); Is their any way to do something like this? I'm trying to do everything with static methods so i do not have to instantiate classes all the time, and have nice clean code which is only being manipulated in one place. The idea behind this is so that there is minimal code repeating and makes things easier to expand on, so for instance another class could implement the BaseFunctionality later on. Thanks Dan

  • problem using fprintf

    - by shiran bar
    I'm trying to print to a text file numerous variables yet it doesn't work. I checked and verified that i write it in the correct syntax. I also checked the return value and it's positive therefore i know it did write to the file, however when i open the file it's empty. I would be happy for some help. This is the code: I initiate DynsaleDayPtr in the main: FILE* DynsaleDayPtr = CreateTextFiles("sale_day.txt"); Create function: FILE* CreateTextFiles (char* fileName) { FILE* saleFilePtr=NULL; if((saleFilePtr=fopen(fileName,"a+"))==NULL) printf("File couldn't be opened\n"); return saleFilePtr; } The call to the function TextAddSale is done from a function that is called in the main: TextAddSale(DynSaleDayPtr,dynNumOfRecords); Bool TextAddSale (FILE* DynsaleDayPtr, int* dynNumOfRecords) { char id[6]; char name [50]; char priceChar[20]; char* tmp = NULL; int price=-1; DynamicRecord * newRec=NULL; scanf("%s%s%s",id,name,priceChar); newRec = (DynamicRecord *)malloc(sizeof(DynamicRecord)); if (newRec == NULL) return False; tmp = (char*)malloc(strlen(name)+1); if (tmp == NULL) { free (newRec); return False; } strcpy(tmp,name); newRec->productName = tmp; strcpy(newRec->productId, id); newRec->productPrice=atoi (priceChar); if (fprintf(DynsaleDayPtr,"%d %s %s %d", strlen(newRec->productName), newRec->productId, newRec->productName, newRec->productPrice)>0) { *dynNumOfRecords=(*dynNumOfRecords)+1; return True; } } thanks!

  • jQuery Toggle switch images

    - by Sixfoot Studio
    Hi Guys, I have a situation where I am not understanding jQuery's Toggle. I have two buttons, both of them open the same content and when you click on either button the content should open or close and the attribute changes the button from open to closed. (So both buttons do the same function). Only thing is, when I click on the top button and it opens my content and then click on the lower button to close it, the image attributes are switched incorrectly. Here's a very stripped down version of what my code looks like and I would appreciate some help. <script language="javascript" type="text/javascript"> $(function () { var open = false; $("#button1, #button2").toggle( function () { open = true; $("#button1").attr("src", "images/btn-open.gif"); $("#button2").attr("src", "images/btn-open.gif"); }, function () { if (open) { $("#button1").attr("src", "images/btn-closed.gif"); $("#button2").attr("src", "images/btn-closed.gif"); } else { $("#button1").attr("src", "images/btn-open.gif"); $("#button2").attr("src", "images/btn-open.gif"); } open = false; } ); }); </script> <img id="button1" src="images/btn-open.gif"></img> <br /> <br /> <br /> <br /> <img id="button2" src="images/btn-open.gif"></img>

    - by kornesh
    I got page A which is a normal HTML page and page which is an AJAX response page. And I want to prevent CSRF attacks by tokens. Lets say I use this method for an autocomplete form, is it possible to use same token multiple times (of course the session is only set one time) because i tired this method but the validation keep failing after the first suggestion (obviously the token has changed, somehow) page A <?php session_start(); $token = md5(uniqid(rand(), TRUE)); $_SESSION['token'] = $token; ?> <input id="token" value="<?php echo $token; ?>" type="hidden"></input> <input id="autocomplete" placeholder="Type something"></input> .... The form is autosubmitted every time theres a change using Jquery. page B <?php session_start(); if($_REQUEST['token'] == $_SESSION['token']){ echo 'Im working fine'; } ?>

  • More than one JPanel in a Frame / having a brackground Image and another Layer with Components on the top

    - by user1905203
    I've got a JFrame with a JPanel in which there is a JLabel with an ImageIcon(). Everything's working perfectly, problem is i now want to add another JPanel with all the other stuff like buttons and so on to the JFrame. But it still shows the background Image on top and nothing with the second JPanel. Can someone help me? Here is an extract of my code: JFrame window = new JFrame("Http Download"); /* * Background Section */ JPanel panel1 = new JPanel(); JLabel lbl1 = new JLabel(); /* * Component Section */ JPanel panel2 = new JPanel(); JLabel lbl2 = new JLabel(); /* * Dimension Section */ Dimension windowSize = new Dimension(800, 600); Dimension screen = Toolkit.getDefaultToolkit().getScreenSize(); public HTTPDownloadGUI() { window.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); panel1.setLayout(null); panel1.setSize(windowSize); panel1.setOpaque(false); panel2.setLayout(null); panel2.setSize(windowSize); panel2.setOpaque(false); lbl1.setSize(windowSize); lbl1.setLocation(0, 0); lbl1.setIcon(new ImageIcon(getClass().getResource("bg1.png"))); panel1.add(lbl1); lbl2.setBounds(0, 0, 100, 100); //lbl2.setIcon(new ImageIcon(getClass().getResource("bg2.png"))); lbl2.setBackground(Color.GREEN); panel2.add(lbl2); panel1.add(panel2); window.add(panel1); int X = (screen.width / 2) - (windowSize.width / 2); int Y = (screen.height / 2) - (windowSize.height / 2); window.setBounds(X,Y , windowSize.width, windowSize.height); window.setVisible(true); }

  • PHP function: find argument's variable name, and function calls line number

    - by Majid
    I want to do something like this for simplifying logging operations. Any idea what I should put in for ?[1]? and ?[2]?? function log_var($var) { $line = ?[1]?; $var_name = ?[2]?; $line--; $filepath = 'log-' . date('Y-m-d'). '.txt'; $message = "$line, $var_name = $var\n"; $fp = fopen($filepath, "a"); fwrite($fp, $message); fclose($fp); @chmod($filepath, 0666); return TRUE; } This how I'd use the function in code (numbers are assumed to be line numbers in actual code): 23 $a = 'hello'; 24 log_var($a); 25 $b = 'bye'; 26 log_var($b); And this is what I want to be written to the log file: 23, a = hello 25, b = bye

  • Does BeginReceive() get everything sent by BeginSend()?

    - by IVlad
    I'm writing a program that will have both a server side and a client side, and the client side will connect to a server hosted by the same program (but by another instance of it, and usually on another machine). So basically, I have control over both aspects of the protocol. I am using BeginReceive() and BeginSend() on both sides to send and receive data. My question is if these two statements are true: Using a call to BeginReceive() will give me the entire data that was sent by a single call to BeginSend() on the other end when the callback function is called. Using a call to BeginSend() will send the entire data I pass it to the other end, and it will all be received by a single call to BeginReceive() on the other end. The two are basically the same in fact. If the answer is no, which I'm guessing is the case based on what I've read about sockets, what is the best way to handle commands? I'm writing a game that will have commands such as PUT X Y. I was thinking of appending a special character (# for example) to the end of each command, and each time I receive data, I append it to a buffer, then parse it only after I encounter a #.

  • how to delete the pluginassembly after AppDomain.Unload(domain)

    - by Ase
    hello, i have a weird problem. i would like to delete an assembly(plugin.dll on harddisk) which is already loaded, but the assembly is locked by the operating system (vista), even if i have unloaded it. f.e. AppDomainSetup setup = new AppDomainSetup(); setup.ShadowCopyFiles = "true"; AppDomain appDomain = AppDomain.CreateDomain(assemblyName + "_AppDomain", AppDomain.CurrentDomain.Evidence, setup); IPlugin plugin = (IPlugin)appDomain.CreateInstanceFromAndUnwrap(assemblyName, "Plugin.MyPlugins"); I also need the assemblyinfos, because I don't know which classes in the pluginassembly implements the IPlugin Interface. It should be possible to have more than one Plugin in one Pluginassembly. Assembly assembly = appDomain.Load(assemblyName); if (assembly != null) { Type[] assemblyTypes = assembly.GetTypes(); foreach (Type assemblyTyp in assemblyTypes) { if (typeof(IPlugin).IsAssignableFrom(assemblyTyp)) { IPlugin plugin = (IPlugin)Activator.CreateInstance(assemblyTyp); plugin.AssemblyName = assemblyNameWithEx; plugin.Host = this; } } } AppDomain.Unload(appDomain); How is it possible to get the assemblyinfos from the appDomain without locking the assembly? best regards

  • Rails using plural table names even though I told it to use singular

    - by Jason Swett
    I tried to run rake test:profile and I got this error: ... Table 'mcif2.accounts' doesn't exist: DELETE FROM `accounts` I know accounts doesn't exist. It's called account. I know Rails uses plural table names by default but here's what my config/environment.rb looks like: # Load the rails application require File.expand_path('../application', __FILE__) # Initialize the rails application McifRails::Application.initialize! ActiveRecord::Base.pluralize_table_names = false And here's what db/schema.rb looks like: ActiveRecord::Schema.define(:version => 0) do create_table "account", :force => true do |t| t.integer "customer_id", :limit => 8, :null => false t.string "account_number", :null => false t.integer "account_type_id", :limit => 8 t.date "open_date", :null => false So I don't understand why Rails still wants to call it accounts sometimes. Any ideas? If it helps give any clues at all, here are the results of grep -ir 'accounts' *.

    - by acidzombie24
    How do i set my window above all other? I need a bad but noticeable msg box that closes on its own. Msg is a dummy form which is empty. All i want is its title. The problems with the code is the window isnt created 0,0 (its just whereever windows feels like putting it).

  • Timer C#. Start, stop, and get the amount of time between the calls

    I'm writing UDP chat with reliable data transfer. I need to start a timer when a packet is sent, and stop it as soon it receives an answer from the server(ACK- acknowledgment). Here is my code: private void sendButton_Click(object sender, EventArgs e) { Packet snd = new Packet(ack, textBox1.Text.Trim()); textBox1.Text = string.Empty; Smsg = snd.GetDataStream();//convert message into array of bytes to send. while (true) { try { // Here I need to Start a timer! clientSock.SendTo(Smsg, servEP); clientSock.ReceiveFrom(Rmsg, ref servEP); //Here I need to stop a timer and get elapsed amount of time. Packet rcv = new Packet(Rmsg); if (Rmsg != null && rcv.ACK01 != ack) continue; if (Rmsg != null && rcv.ACK01 == ack) { this.displayMessageDelegate("ack is received :"+ack); ChangeAck(ack); break; } Thank you.

  • Huge burst of memory in c# service, what could be the cause?

    - by Daniel
    I'm working on a c# service application and i have this problem where out of no where and for no obvious reason, the memory for the process will climb from 150mb to almost 2gb in about 5 seconds and then back to 150mb. But nothing in our system should be using any where near that amount of memory (so its probably a bug somewhere). It might be a tight while true loop somewhere but the cpu usage at the time was very low so i thought i'd look for other ideas. Now the weirder thing is when i compile the service for 64bit, the same massive burst will occur except it exceeded 10gb of ram (paging most of it) and it just caused lots of problems with the computer and everything running on it. After a while it shuts down but it looks like windows is still willing to give it more memory. Would you have any ideas or tools that i can use in order to find this? Yes it has lots of logging however nothing in the logs stand out as to why this is happening. I can run the service in a console app mode, so my next test was going to be running it in visual studio debugger and see if i can find anything. It only happens occasionally but usually about 10-20 minutes after startup. On 32bit mode it cleans up and continues on like normally. 64bit mode it crashes after a while and uses stupid amounts of memory. But i'm really stumped as to why this is happening!!!

  • Why does defined(X) not work in a preprocessor definition without a space?

    - by Devin
    A preprocessor definition that includes defined(X) will never evaluate to true, but (defined X) will. This occurs in MSVC9; I have not tested other preprocessors. A simple example: #define FEATURE0 1 #define FEATURE1 0 #define FEATURE2 1 #define FEATURE3 (FEATURE0 && !FEATURE1 && (defined(FEATURE2))) #define FEATURE4 (FEATURE0 && !FEATURE1 && (defined FEATURE2)) #define FEATURE5 (FEATURE0 && !FEATURE1 && (defined (FEATURE2))) #if FEATURE3 #pragma message("FEATURE3 Enabled") #elif (FEATURE0 && !FEATURE1 && (defined(FEATURE2))) #pragma message("FEATURE3 Enabled (Fallback)") #endif #if FEATURE4 #pragma message("FEATURE4 Enabled") #elif (FEATURE0 && !FEATURE1 && (defined FEATURE2)) #pragma message("FEATURE4 Enabled (Fallback)") #endif #if FEATURE5 #pragma message("FEATURE5 Enabled") #elif (FEATURE0 && !FEATURE1 && (defined (FEATURE2))) #pragma message("FEATURE5 Enabled (Fallback)") #endif The output from the compiler is: 1FEATURE3 Enabled (Fallback) 1FEATURE4 Enabled 1FEATURE5 Enabled Working cases: defined (X), defined( X ), and defined X. Broken case: defined(X) Why is defined evaluated differently when part of a definition, as in the #if cases in the example, compared to direct evaluation, as in the #elif cases in the example?

  • How do I code a tree of objects in Haskell with pointers to parent and children?

    - by axilmar
    I've got the following problem: I have a tree of objects of different classes where an action in the child class invalidates the parent. In imperative languages, it is trivial to do. For example, in Java: public class A { private List<B> m_children = new LinkedList<B>(); private boolean m_valid = true; public void invalidate() { m_valid = false; } public void addChild(B child) { m_children.add(child); child.m_parent = this; } } public class B { public A m_parent = null; private int m_data = 0; public void setData(int data) { m_data = 0; m_parent.invalidate(); } } public class Main { public static void main(String[] args) { A a = new A(); B b = new B(); b.setData(0); //invalidates A } } How do I do the above in Haskell? I cannot wrap my mind around this, since once I construct an object in Haskell, it cannot be changed. I would be much obliged if the relevant Haskell code is posted.

  • How do I create a self referential association (self join) in a single class using ActiveRecord in Rails?

    - by Daniel Chang
    I am trying to create a self join table that represents a list of customers who can refer each other (perhaps to a product or a program). I am trying to limit my model to just one class, "Customer". The schema is: create_table "customers", force: true do |t| t.string "name" t.integer "referring_customer_id" t.datetime "created_at" t.datetime "updated_at" end add_index "customers", ["referring_customer_id"], name: "index_customers_on_referring_customer_id" My model is: class Customer < ActiveRecord::Base has_many :referrals, class_name: "Customer", foreign_key: "referring_customer_id", conditions: {:referring_customer_id => :id} belongs_to :referring_customer, class_name: "Customer", foreign_key: "referring_customer_id" end I have no problem accessing a customer's referring_customer: @customer.referring_customer.name ... returns the name of the customer that referred @customer. However, I keep getting an empty array when accessing referrals: @customer.referrals ... returns []. I ran binding.pry to see what SQL was being run, given a customer who has a "referer" and should have several referrals. This is the SQL being executed. Customer Load (0.3ms) SELECT "customers".* FROM "customers" WHERE "customers"."id" = ? ORDER BY "customers"."id" ASC LIMIT 1 [["id", 2]] Customer Exists (0.2ms) SELECT 1 AS one FROM "customers" WHERE "customers"."referring_customer_id" = ? AND "customers"."referring_customer_id" = 'id' LIMIT 1 [["referring_customer_id", 3]] I'm a bit lost and am unsure where my problem lies. I don't think my query is correct -- @customer.referrals should return an array of all the referrals, which are the customers who have @customer.id as their referring_customer_id.

  • Nullable values in C++

    - by DanDan
    I'm creating a database access layer in native C++, and I'm looking at ways to support NULL values. Here is what I have so far: class CNullValue { public: static CNullValue Null() { static CNullValue nv; return nv; } }; template<class T> class CNullableT { public: CNullableT(CNullValue &v) : m_Value(T()), m_IsNull(true) { } CNullableT(T value) : m_Value(value), m_IsNull(false) { } bool IsNull() { return m_IsNull; } T GetValue() { return m_Value; } private: T m_Value; bool m_IsNull; }; This is how I'll have to define functions: void StoredProc(int i, CNullableT<int> j) { ...connect to database ...if j.IsNull pass null to database etc } And I call it like this: sp.StoredProc(1, 2); or sp.StoredProc(3, CNullValue::Null()); I was just wondering if there was a better way than this. In particular I don't like the singleton-like object of CNullValue with the statics. I'd prefer to just do sp.StoredProc(3, CNullValue); or something similar. How do others solve this problem?

  • How to show and update popup in 1 thread

    - by user3713986
    I have 1 app. 2 Forms are MainFrm and PopupFrm, 1 thread to update some information to PopupFrm Now to update PopupFrm i use: In MainFrm.cs private PopupFrm mypop; MainFrm() { .... PopupFrm mypop= new PopupFrm(); mypop.Show(); } MyThread() { Process GetData();... mypop.Update(); ... } In PopupFrm.cs public void Update() { this.Invoke((MethodInvoker)delegate .... }); } Problem here that mypopup alway display when MainFrm display (Start application not when has data to update). So i change MainFrm.cs to : private PopupFrm mypop; private bool firstdisplay=false; MainFrm() { .... PopupFrm mypop= new PopupFrm(); //mypop.Show(); } MyThread() { Process GetData();... if(!firstdisplay) { mypop.Show(); firstdisplay=true; } mypop.Update(); ... } But it can not update Popup GUI. So how can i fix this issue ? Thanks all.

  • JQM Nested Popups

    - by mcottingham
    I am having a hard time with the new Alpha release of JQM not showing nested popups. For example, I am displaying a popup form that the user is supposed to fill out, if the server side validation fails, I want to display an error popup. I am finding that the error popup is not being shown. I suspect that it is being shown below the original popup. function bindSongWriterInvite() { // Bind the click event of the invite button $("#invite-songwriter").click(function () { $("#songwriter-invite-popup").popup("open"); }); // Bind the invitation click event of the invite modal $("#songwriter-invite-invite").click(function () { if ($('#songwriter-invite').valid()) { $('#songwriter-invite-popup').popup('close'); $.ajax({ type: 'POST', async: true, url: '/songwriter/jsoncreate', data: $('#songwriter-invite').serialize() + "&songName=" + $("#Song_Title").val(), success: function (response) { if (response.state != "success") { alert("Should be showing error dialog"); mobileBindErrorDialog(response.message); } else { mobileBindErrorDialog("Success!"); } }, failure: function () { mobileBindErrorDialog("Failure!"); }, dataType: 'json' }); } }); // Bind the cancel click event of the invite modal $("#songwriter-invite-cancel").click(function () { $("#songwriter-invite-popup").popup("close"); }); } function mobileBindErrorDialog(errorMessage) { // Close all open popups. This is a work around as the JQM Alpha does not // open new popups in front of all other popups. var error = $("<div></div>").append("<p>" + errorMessage + "</p>") .popup(); $(error).popup("open"); } So, you can see that I attempt to show the error dialog regardless of whether the ajax post succeeds or fails. It just never shows up. Anyone have any thoughts? Mike

  • Strange output produced by program

    - by Boom_mooB
    I think that my code works. However, it outputs 01111E5, or 17B879DD, or something like that. Can someone please tell me why. I am aware that I set the limit of P instead of 10,001. My code is like that because I start with 3, skipping the prime number 2. #include <iostream> bool prime (int i) { bool result = true; int isitprime = i; for(int j = 2; j < isitprime; j++) ///prime number tester { if(isitprime%j == 0) result = false; } return result; } int main (void) { using namespace std; int PrimeNumbers = 1; int x = 0; for (int i = 3 ; PrimeNumbers <=10000; i++) { if(prime(i)) { int prime = i; PrimeNumbers +=1; } } cout<<prime<<endl; system ("pause"); return 0; }
