  • How To Send A Confirmation Number To Others And Myself?

    - by user2913307
    On my website I have a reservation form. Once someone clicks submit a confirmation number comes up (that number is different everytime). I get an e-mail with everything the person filled out on my reservation form but I want to know their confirmation number as well. RANDOM NUMBER CODE $(document).ready(function() { var ranval = Math.floor((Math.random()*10000)+1); $('input[name=lblrand]').val(ranval); // bind 'myForm' and provide a simple callback function $('#myForm').ajaxForm(function() { alert("Your Message has been sent!Your Form Registration Number is: "+ ranval); $('#myForm').resetForm(); WHAT GETS E-MAILED TO ME $('#rSubmit').click(function(){ var data = {}; data.to = "[email protected]"; data.from = "[email protected]>"; data.subject = "New Reservation"; data.message = "New Reservation from Website \n"+ '\n First Name : '+$('#name').val()+ '\n Last Name : '+$('#lastname').val() + '\n Confirmation : '+$('#lblrand').val () + '\n Coupon Code : '+$('#coupon').val() + '\n Company Name : '+$('#company').val() + '\n Phone Number : '+$('#phone').val() + '\n Street Address : '+$('#street').val() + '\n Pick-Up City : '+$('#city').val()+ '\n Pick-Up State : '+$('#state').val() + '\n Pick-Up Zip : '+$('#zip').val() + '\n Date : '+$('#calendar').val()+ '\n Time : '+$('#time').val() + '\n Time : '+$('#time2').val() + '\n Time : '+$('#time3').val() + '\n Airport : '+$('#airport').val() + '\n Airline : '+$('#airline').val() + '\n Flight # : '+$('#fnumber').val() + '\n Stops : '+$('#hstops').val() + '\n Stops Info : '+$('#info').val() + '\n Passengers : '+$('#passengers').val() + '\n Luggages : '+$('#luggages').val()+ '\n Car Seat : '+$('#seat').val()+ '\n Drop-Off Street : '+$('#dostreet').val() + '\n Drop-Off City : '+$('#docity').val()+ '\n Drop-Off State : '+$('#dostate').val() + '\n Drop-Off Zip : '+$('#dozip').val() + '\n D.O Airport : '+$('#doairport').val() + '\n D.O Airline : '+$('#doairline').val() + '\n Flight # : '+$('#dofnumber').val() + '\n Date : '+$('#calendar2').val()+ '\n Time : '+$('#rtime').val() + '\n Time : '+$('#rtime2').val() + '\n Time : '+$('#rtime3').val() + '\n Return Street : '+$('#rtstreet').val() + '\n Return City : '+$('#rtcity').val()+ '\n Return State : '+$('#rtstate').val() + '\n Return Zip : '+$('#rtzip').val() + '\n Return Airport : '+$('#rtairport').val() + '\n Return Airline : '+$('#rtairline').val() + '\n Return Flight # : '+$('#rtfnumber').val() + '\n Payment Type : '+$('#payment').val() + '\n Card Number : '+$('#creditcardno').val() + '\n Exp.

  • Set a specific stylesheet based on session variable in javascript

    - by user2371301
    I have an option for a user to select his/her own theme while logged into the system and this theme is set in a MYSQL Database and called each time the user logs in, this is called by: <?php $_SESSION['SESS_THEME_NAME']; ?> Now, I had this working in a PHP file but I need it to work in Javascript instead unfortunately. And I need some help. I looked at the code using the developers tools on Google Chrome and looks like the above code is not resolving within the javascript file. Which makes sense because you can't access session variables within a javascript file (as I found by searching Google.) The code is basically supposed to set the specific stylesheet based on the value extracted from the MYSQL database. So if the database says Default the script needs to tell the webpage to use the default.css file. And so on and so forth. My attempt at writing this is as follows: var themName="<?php $_SESSION['SESS_THEME_NAME']; ?>"; if (themeName == "Default") { document.write("<link re='stylesheet' type='text/css' href='css/mws-theme.css'>"); }; if (themeName == "Army") { document.write("<link rel='stylesheet' type='text/css' href='css/mws-theme-army.css'>"); }; if (themeName == "Rocky Mountains") { document.write("<link rel='stylesheet' type='text/css' href='css/mws-theme-rocky.css'>"); }; if (themeName == "Chinese Temple") { document.write("<link rel='stylesheet' type='text/css' href='css/mws-theme-chinese.css'>"); }; if (themeName == "Boutique") { document.write("<link rel='stylesheet' type='text/css' href='css/mws-theme-boutique.css'>"); }; if (themeName == "Toxic") { document.write("<link rel='stylesheet' type='text/css' href='css/mws-theme-toxic.css'>"); }; if (themeName == "Aquamarine") { document.write("<link rel='stylesheet' type='text/css' href='css/mws-theme-aquamarine.css'>"); }; Any help once so ever would be awesome and much much appreciated! I am reaching a deadline :/

  • Why does firefox round-trip to the server to determine whether my files are modifed?

    - by erikkallen
    I have some static content on my web site that I have set up caching for (using Asp.NET MVC). According to Firebug, the first time I open the page, Firefox sends this request: GET /CoreContent/Core.css?asm=0.7.3614.34951 Host: 127.0.0.1:3916 User-Agent: Mozilla/5.0 (Windows; U; Windows NT 6.1; en-US; rv:1.9.1.5) Gecko/20091102 Firefox/3.5.5 (.NET CLR 3.5.30729) Accept: text/css,*/*;q=0.1 Accept-Language: en-us,en;q=0.5 Accept-Encoding: gzip,deflate Accept-Charset: ISO-8859-1,utf-8;q=0.7,*;q=0.7 Keep-Alive: 300 Connection: keep-alive Referer: http://127.0.0.1:3916/Edit/1/101 Cookie: .ASPXAUTH=52312E5A802C1A079E2BA29AA2BFBC5A38058977B84452D62ED52855D4164659B4307661EC73A307BFFB2ED3871C67CB3A9AAFDB3A75A99AC0A21C63A6AADE9A11A7138C672E75125D9FF3EFFBD9BF62 Pragma: no-cache Cache-Control: no-cache Which my server replies to with this: Server: ASP.NET Development Server/9.0.0.0 Date: Mon, 23 Nov 2009 18:44:41 GMT X-AspNet-Version: 2.0.50727 X-AspNetMvc-Version: 1.0 Cache-Control: public, max-age=31535671 Expires: Tue, 23 Nov 2010 18:39:12 GMT Last-Modified: Mon, 23 Nov 2009 18:39:12 GMT Vary: * Content-Type: text/css Content-Length: 15006 Connection: Close So far, so good.

Why does Firefox issue this second request? In the first response, I said that the cache does not expire for a year (I intend to use query parameters whenever things change). Do I have to add another response header to prevent this extra roundtrip? Edit: It does not matter whether I press refresh, or whether I go to the page again (or a different URL, which references the same external files). Firefox does the same again. Also, I don't claim this to be a bug in FF, I just wonder if there is another header I can set which means "This document will never change, don't bother me again".

  • Smoke testing a .NET web application

    - by pdr
    I cannot believe I'm the first person to go through this thought process, so I'm wondering if anyone can help me out with it. Current situation: developers write a web site, operations deploy it. Once deployed, a developer Smoke Tests it, to make sure the deployment went smoothly. To me this feels wrong, it essentially means it takes two people to deploy an application; in our case those two people are on opposite sides of the planet and timezones come into play, causing havoc. But the fact remains that developers know what the minimum set of tests is and that may change over time (particularly for the web service portion of our app). Operations, with all due respect to them (and they would say this themselves), are button-pushers who need a set of instructions to follow. The manual solution is that we document the test cases and operations follow that document each time they deploy. That sounds painful, plus they may be deploying different versions to different environments (specifically UAT and Production) and may need a different set of instructions for each. On top of this, one of our near-future plans is to have an automated daily deploy environment, so then we'll have to instruct a computer as to how to deploy a given version of our app. I would dearly like to add to that instructions for how to smoke test the app. Now developers are better at documenting instructions for computers than they are for people, so the obvious solution seems to be to use a combination of nUnit (I know these aren't unit tests per se, but it is a built-for-purpose test runner) and either the Watin or Selenium APIs to run through the obvious browser steps and call to the web service and explain to the Operations guys how to run those unit tests. I can do that; I have mostly done it already. But wouldn't it be nice if I could make that process simpler still? At this point, the Operations guys and the computer are going to have to know which set of tests relate to which version of the app and tell the nUnit runner which base URL it should point to (say, www.example.com = v3.2 or test.example.com = v3.3). Wouldn't it be nicer if the test runner itself had a way of giving it a base URL and letting it download say a zip file, unpack it and edit a configuration file automatically before running any test fixtures it found in there? Is there an open source app that would do that? Is there a need for one? Is there a solution using something other than nUnit, maybe Fitnesse? For the record, I'm looking at .NET-based tools first because most of the developers are primarily .NET developers, but we're not married to it. If such a tool exists using other languages to write the tests, we'll happily adapt, as long as there is a test runner that works on Windows.

  • Algorithm to split an article without breaking the reading flow or HTML code

    - by Victor Stanciu
    Hello, I have a very large database of articles, of varying lengths. The articles have HTML elements in them. I have to insert some ads (simple <script> elements) in the body of each article when it is displayed (I know, I hate ads that interrupt my reading too). Now, the problem is that each ad must be inserted at about the same position in each article. The simplest solution is to simply split the article on a fixed number of characters (without breaking words), and insert the ad code. This, however, runs the risk of inserting the ad in the middle of a HTML tag. I could go the regex way, but I was thinking about the following solution, using JS: Establish a character count threshold. For example, "the add should be inserted at about 200 words" Set accepted deviations in each direction, say -20, +20 characters. Loop through each text node inside the article, and while doing so, keep count of the total number of characters so far Once the count exceeds the threshold, make the following decision: 4.1. If count exceeds the threshold by a value lower that the positive accepted deviation (for example, 17 characters), insert the ad code just after the current text node. 4.2. If the count is greater than the sum of the threshold and the deviation, roll back to the previous text node, and make the same decision, only this time use the previous count and check if it's lower than the difference between the threshold and the deviation, and if not, insert the ad between the current node and the previous one. 4.3. If the 4.1 and 4.2 fail (which means that the previous node reached a too low character count and the current node a too high one), insert the ad after whatever character count is needed inside the current element. I know it's convoluted, but it's the first thing out of my mind and it has the advantage that, by trying to insert the ad between text nodes, perhaps it will not break the flow of the article as bad as it would if I would just stick it in (like the final 4.3 case) Here is some pseudo-code I put together, I don't trust my english-explaining skills: threshold = 200 deviation = 20 current_count = 0 for each node in article_nodes { previous_count = current_count current_count = current_count + node.length if current_count < threshold { continue // next interation } if current_count > threshold + deviation { if previous_count < threshdold - deviation { // insert ad in current node } else { // insert ad between the current and previous nodes } } else { // insert ad after the current node } break; } Am I over-complicating stuff, or am I missing a simpler, more elegant solution?

  • Same data being returned by linq for 2 different executions of a stored procedure?

    - by Paul
    Hello I have a stored procedure that I am calling through Entity Framework. The stored procedure has 2 date parameters. I supply different argument in the 2 times I call the stored procedure. I have verified using SQL Profiler that the stored procedure is being called correctly and returning the correct results. When I call my method the second time with different arguments, even though the stored procedure is bringing back the correct results, the table created contains the same data as the first time I called it. dtStart = 01/08/2009 dtEnd = 31/08/2009 public List<dataRecord> GetData(DateTime dtStart, DateTime dtEnd) { var tbl = from t in db.SP(dtStart, dtEnd) select t; return tbl.ToList(); } GetData((new DateTime(2009, 8, 1), new DateTime(2009, 8, 31)) // tbl.field1 value = 45450 - CORRECT GetData(new DateTime(2009, 7, 1), new DateTime(2009, 7, 31)) // tbl.field1 value = 45450 - WRONG 27456 expected Is this a case of Entity Framework being clever and caching? I can't see why it would cache this though as it has executed the stored procedure twice. Do I have to do something to close tbl? using Visual Studio 2008 + Entity Framework. I also get the message "query cannot be enumerated more than once" a few times every now and then, am not sure if that is relevant?

  • Supporting multiple instances of a plugin DLL with global data

    - by Bruno De Fraine
    Context: I converted a legacy standalone engine into a plugin component for a composition tool. Technically, this means that I compiled the engine code base to a C DLL which I invoke from a .NET wrapper using P/Invoke; the wrapper implements an interface defined by the composition tool. This works quite well, but now I receive the request to load multiple instances of the engine, for different projects. Since the engine keeps the project data in a set of global variables, and since the DLL with the engine code base is loaded only once, loading multiple projects means that the project data is overwritten. I can see a number of solutions, but they all have some disadvantages: You can create multiple DLLs with the same code, which are seen as different DLLs by Windows, so their code is not shared. Probably this already works if you have multiple copies of the engine DLL with different names. However, the engine is invoked from the wrapper using DllImport attributes and I think the name of the engine DLL needs to be known when compiling the wrapper. Obviously, if I have to compile different versions of the wrapper for each project, this is quite cumbersome. The engine could run as a separate process. This means that the wrapper would launch a separate process for the engine when it loads a project, and it would use some form of IPC to communicate with this process. While this is a relatively clean solution, it requires some effort to get working, I don't now which IPC technology would be best to set-up this kind of construction. There may also be a significant overhead of the communication: the engine needs to frequently exchange arrays of floating-point numbers. The engine could be adapted to support multiple projects. This means that the global variables should be put into a project structure, and every reference to the globals should be converted to a corresponding reference that is relative to a particular project. There are about 20-30 global variables, but as you can imagine, these global variables are referenced from all over the code base, so this conversion would need to be done in some automatic manner. A related problem is that you should be able to reference the "current" project structure in all places, but passing this along as an extra argument in each and every function signature is also cumbersome. Does there exist a technique (in C) to consider the current call stack and find the nearest enclosing instance of a relevant data value there? Can the stackoverflow community give some advice on these (or other) solutions?

  • Throwing cats out of windows

    - by AndrewF
    Imagine you're in a tall building with a cat. The cat can survive a fall out of a low story window, but will die if thrown from a high floor. How can you figure out the longest drop that the cat can survive, using the least number of attempts? Obviously, if you only have one cat, then you can only search linearly. First throw the cat from the first floor. If it survives, throw it from the second. Eventually, after being thrown from floor f, the cat will die. You then know that floor f-1 was the maximal safe floor. But what if you have more than one cat? You can now try some sort of logarithmic search. Let's say that the build has 100 floors and you have two identical cats. If you throw the first cat out of the 50th floor and it dies, then you only have to search 50 floors linearly. You can do even better if you choose a lower floor for your first attempt. Let's say that you choose to tackle the problem 20 floors at a time and that the first fatal floor is #50. In that case, your first cat will survive flights from floors 20 and 40 before dying from floor 60. You just have to check floors 41 through 49 individually. That's a total of 12 attempts, which is much better than the 50 you would need had you attempted to use binary elimination. In general, what's the best strategy and it's worst-case complexity for an n-storied building with 2 cats? What about for n floors and m cats? Assume that all cats are equivalent: they will all survive or die from a fall from a given window. Also, every attempt is independent: if a cat survives a fall, it is completely unharmed. This isn't homework, although I may have solved it for school assignment once. It's just a whimsical problem that popped into my head today and I don't remember the solution. Bonus points if anyone knows the name of this problem or of the solution algorithm.

  • jQuery tablesorter - loss of functionality after AJAX call

    - by Nick
    I have recently been experimenting with the tablesorter plugin for jQuery. I have successfully got it up and running in once instance, and am very impressed. However, I have tried to apply the tablesorter to a different table, only to encounter some difficulties... Basically the table causing a problem has a <ul> above it which acts as a set of tabs for the table. so if you click one of these tabs, an AJAX call is made and the table is repopulated with the rows relevant to the specific tab clicked. When the page initially loads (i.e. before a tab has been clicked) the tablesorter functionality works exactly as expected. But when a tab is clicked and the table repopulated, the functionality disappears, rendering it without the sortable feature. Even if you go back to the original tab, after clicking another, the functionality does not return - the only way to do so is a physical refresh of the page in the browser. I have seen a solution which seems similar to my problem on this site, and someone recommends using the jQuery plugin, livequery. I have tried this but to no avail :-( If someone has any suggestions I would be most appreciative. I can post code snippets if it would help (though I know the instantiation code for tablesorter is fine as it works on tables with no tabs - so it's definitely not that!) EDIT: As requested, here are some code snippets: The table being sorted is <table id="#sortableTable#">..</table>, the instantiation code for tablesorter I am using is: $(document).ready(function() { $("#sortableTable").tablesorter( { headers: //disable any headers not worthy of sorting! { 0: { sorter: false }, 5: { sorter: false } }, sortMultiSortKey: 'ctrlKey', debug:true, widgets: ['zebra'] }); }); And I tried to rig up livequery as follows: $("#sortableTable").livequery(function(){ $(this).tablesorter(); }); This has not helped though... I am not sure whether I should use the id of the table with livequery as it is the click on the <ul> I should be responding to, which is of course not part of the table itself. I have tried a number of variations in the hope that one of them will help, but to no avail :-(

  • Pop-Up Window at inital start up, of android application

    - by Josh Fairbank
    I am trying to find a code that will do a popup at the initial start up on an installed app. Much like a changelog that is starting to appear in more and more apps. I have found some similar codes, but being a beginner I haven't been able to figure out where to exactly put the code in and I always have tons of errors that still do not work once I try and fix them. I am working in Eclipse with an android project, and I'm using a webview to show a website.

  • Generating custom-form documents from base-form plus XML?

    - by KlaymenDK
    Hi all, this is my first stack overflow, and it's a complex one. Sorry. My task is to generate custom documents from a basic template plus some XML without having a custom form design element for each case. Here's the whole picture: We are building a Lotus Notes (client, not web) application for world-wide application access control; the scope is something like 400.000 users being able to request access to any of 1000+ applications. Each application needs its own request form -- different number of approvers, various info required, that sort of thing. We simply can't have a thousand forms in a database (one per application), and anyway their maintenance really needs to be pushed from the developers to the application owners. So instead of custom forms, we'd like to create a generic "template" form that stores a block of basic fields, but then allows application owners to define another block of fields dynamically -- "I want a mandatory plain-text field named 'Name' here, and then a date field named 'Due' here that must be later than today's date, and then ...". I hope this makes sense (if not, think of it as a generic questionnaire application). I pretty much have the structure in place for designing the dynamic fields (form builder GUI - XML-encoded data - pre-rendered DXL for injecting into a form), including mark-up for field types, value options, and rudimentary field validation instructions. My problem is generating a document with this dynamic content injected at the proper location (without needing a custom form design element for each case). Doing the dynamic content via HTML is out. The Notes client web rendering is simply way too poor, and it would be quite a challenge to implement things like field validation instructions, date selectors, and name look-ups. DXL, on the other hand, would allow us to use native Notes fields and code. As a tech demo, I've managed to implement a custom form generator that injects the pre-rendered DXL for the dynamic content into a base form; but as I said, we don't want a ton of custom form design elements. I've tried to implement a way to create a document with the "store form in document" flag set, but once I've created the document from the base form, I can't get DXL access to the stored form design, and so I can't inject my dynamic content. I know this is not something Notes was ever intended to do. Has anyone ever tried something like it (and gotten away with it)? Thanks for reading this far. With a boatload of thanks in advance, Jan Gundtofte-Bruun

  • How do I solve "405 Method Not Allowed" for our subversion setup?

    - by macke
    We're serving our source code using VisualSVN running on Windows Server 2003. Recently, we split a portion of a project into a new project in it's own repository, and then linked it back to the original project using svn:externals. Since then, we've been having issues when we try to commit files with Subclipse. The error we're getting is: svn: Commit failed (details follow): svn: PROPFIND of '/svn': 405 Method Not Allowed (https://svn.ourserver.com) Googling for a while didn't really help, our config seems to be correct. It should also be noted that we've been running this server for a while no without these problems and apart from splitting the project into two repositories, no changes have been made to the server (ie, config files are the same). It should also be noted that these errors only appear when we try to check in multiple files at once. If we check in one file at a time there are no errors. Also, it only appears in Subclipse as far as we know right now, Versions.app (OS X) seems to work fine so that is our current workaround. So, the questions is how do I analyze the error to find the cause and subsequently fix it? I'm by no means a svn guru and right now I'm clueless. EDIT: It seems we can check in multiple files in the same package, but not files from multiple packages. Also, when I "split" the project into two repositories, I imported the original repository with a new name. I did not do a dump and then import that dump. Could that be the source of our issues, and if so, how would I solve that? EDIT: After some jerking around it seems as though it is indeed related to when checking in files in different repositories. If I try to do a single commit in both Repo A and Repo B (referenced by svn:externals) at the same time, I get the error. Versions.app handles this correctly, but I guess it might just be doing two commits, not a single one. Subclipse fails miserably. For now, we simply do multiple commits, one for Repo A and one for Repo B, that works just fine. If anyone smarter than me could fill in the details why this is happening, whether or not this kind of setup is stupid etc, please go right ahead.

  • C++: Templates for static functions?

    - by Rosarch
    I have a static Utils class. I want certain methods to be templated, but not the entire class. How do I do this? This fails: #pragma once #include <string> using std::string; class Utils { private: template<class InputIterator, class Predicate> static set<char> findAll_if_rec(InputIterator begin, InputIterator end, Predicate pred, set<char> result); public: static void PrintLine(const string& line, int tabLevel = 0); static string getTabs(int tabLevel); template<class InputIterator, class Predicate> static set<char> Utils::findAll_if(InputIterator begin, InputIterator end, Predicate pred); }; Error: utils.h(10): error C2143: syntax error : missing ';' before '<' utils.h(10): error C4430: missing type specifier - int assumed. Note: C++ does not support default-int utils.h(10): error C4430: missing type specifier - int assumed. Note: C++ does not support default-int utils.h(10): error C2238: unexpected token(s) preceding ';' utils.h(10): error C2988: unrecognizable template declaration/definition utils.h(10): error C2059: syntax error : '<' What am I doing wrong? What is the correct syntax for this? Incidentally, I'd like to templatize the return value, too. So instead of: template<class InputIterator, class Predicate> static set<char> findAll_if_rec(InputIterator begin, InputIterator end, Predicate pred, set<char> result); I'd have: template<class return_t, class InputIterator, class Predicate> static return_t findAll_if_rec(InputIterator begin, InputIterator end, Predicate pred, set<char> result); How would I specify that: 1) return_t must be a set of some sort 2) InputIterator must be an iterator 3) InputIterator's type must work with return_t's type. Thanks.

  • I have to select the checkbox two times to check/uncheck in jTable

    - by 117526709403775781607
    I have a jTable code i intend to use, but the problem with it is that when i click on the checkbox once it doesn't select/deselect it, instead i have to click twice. But if i select any other cell in the row except the one containing the checkbox the purpose is solved. HERE IS MY CODE : public class TableSelectionTest extends JFrame implements ListSelectionListener { private final int COLUMN_COUNT = 5; private TblModel model; public TableSelectionTest() { initialize(); setDefaultCloseOperation(EXIT_ON_CLOSE); pack(); } private void initialize() { List data = new ArrayList(); for (int i = 0; i < 10; i++) { Object record[] = new Object[COLUMN_COUNT]; record[0] = Boolean.FALSE; for (int j = 1; j < COLUMN_COUNT; j++) { record[j] = new Integer(j); } data.add(record); } model = new TblModel(data); JTable table = new JTable(model); table.getSelectionModel().setSelectionMode(ListSelectionModel.SINGLE_SELECTION); table.getSelectionModel().addListSelectionListener (this); JScrollPane scroll = new JScrollPane(table); getContentPane().add(scroll, BorderLayout.CENTER); } public static void main(String[] args) { TableSelectionTest f = new TableSelectionTest(); f.show(); } class TblModel extends AbstractTableModel { private List data; public TblModel(List data) { this.data = data; } public int getColumnCount() { return COLUMN_COUNT; } public int getRowCount() { return data == null ? 0 : data.size(); } public void setValueAt(Object value, int rowIndex, int columnIndex) { getRecord(rowIndex)[columnIndex] = value; super.fireTableCellUpdated(rowIndex, columnIndex); } public Object getValueAt(int rowIndex, int columnIndex) { return getRecord(rowIndex)[columnIndex]; } public boolean isCellEditable(int rowIndex, int columnIndex) { if(columnIndex == 0) return true; else return false; } public Class getColumnClass(int columnIndex) { if (data == null || data.size() == 0) { return Object.class; } Object o = getValueAt(0, columnIndex); return o == null ?

  • iPhone app works hundreds of times, then crashes from memory error on startup, then never works unti

    - by peter
    I have a Cocos2d/openGL iPhone game. It's a universal app and I'm dealing with an occasional but nasty error on the iPad. We are loading a lot of textures up front (3 2048x2048 textures). I'm working on reducing this up front load, but what worries me is I really don't understand the root cause of this crash that permanently breaks the app. This is the deal: 1. App works fine for hundreds of plays on the iPad 2. Eventually (I'm guessing due to other programs using up some memory and not letting go or whatever) the app starts crashing on startup. It just closes again in the middle of loading. 3. The App will now never work again on that iPad, closing immediately every time, until the iPad is restarted. Obviously my app is demanding too much memory up front to work reliably every time, I get that. What I don't get is why when it fails once, it has failed forever until the iPad is restarted. Can anyone explain what is going on here? EDIT: forgot to add organizer crash lags just say low memory, like this every time (I changed my app name to MyAppName below). Again, I know it's low memory, but why does it stay low memory until restart?: Incident Identifier: E7A2507C-3FB1-4E3B-B315-09F094236541 CrashReporter Key: 0fda9d667f2c6073f20a76809aa25438b6854d15 OS Version: iPhone OS 3.2 (7B367) Date: 2010-04-30 16:59:44 -0400 Free pages: 437 Wired pages: 17228 Purgeable pages: 0 Largest process: MyAppName Processes Name UUID Count resident pages MyAppName <6307ce41802850944baa78d29224fa7f> 22385 (jettisoned) (active) mediaserverd <ea8bac28b06fe3980fdd44b5caceb563> 242 DTMobileIS <a0f651e43881e66f50f8a95abea72921> 5826 notification_pro <4c9a7ee0a5bbe160465991228f2d2f2e> 67 syslog_relay <4ceaed776d2df957fa130712f4ef21d0> 66 notification_pro <4c9a7ee0a5bbe160465991228f2d2f2e> 67 notification_pro <4c9a7ee0a5bbe160465991228f2d2f2e> 67 afcd <4f3c9566e33b4463f05603d990584e5d> 72 ptpd <83de0f774bd6553d513ae9e19b0f9b56> 181 syslogd <66247e305d5c0bf6f1ce1cc950653263> 81 lsd <a4d852c1c8da2b3d231bdc90887b52ba> 130 iapd <a8534cbde4b90ad5915dd26ab03ff3e3> 204 notifyd <5e9d5bee7c3eae1c8b494c79eb11406e> 71 BTServer <64e4a6ea6b1240db2331e05a29caa862> 108 CommCenter <97bf297944ac4bde19bcee96dd23bd5f> 181 SpringBoard <c7a5904c12db7b14334a4edaa4cabaa9> 5339 (active) configd <aca9fa3380322669164fd6b1a3864300> 373 fairplayd.K48 <2d997ffca1a568f9c5400ac32d8f0782> 84 locationd <dd1ea88105c62173908ce767db5c4d37> 599 mDNSResponder <820560222d47a1f2a0dce98a7f8a9721> 108 lockdownd <497fd54c79a680bf29f5d9320f514613> 303 MobileStorageMou <c277b79c2157c4dc5cfc5c3ca35bd5f2> 69 launchd <66972eee4d865c4383b33d985d22994b> 98 **End**

  • Scalable Database Tagging Schema

    - by Longpoke
    EDIT: To people building tagging systems. Don't read this. It is not what you are looking for. I asked this when I wasn't aware that RDBMS all have their own optimization methods, just use a simple many to many scheme. I have a posting system that has millions of posts. Each post can have an infinite number of tags associated with it. Users can create tags which have notes, date created, owner, etc. A tag is almost like a post itself, because people can post notes about the tag. Each tag association has an owner and date, so we can see who added the tag and when. My question is how can I implement this? It has to be fast searching posts by tag, or tags by post. Also, users can add tags to posts by typing the name into a field, kind of like the google search bar, it has to fill in the rest of the tag name for you. I have 3 solutions at the moment, but not sure which is the best, or if there is a better way. Note that I'm not showing the layout of notes since it will be trivial once I get a proper solution for tags. Method 1. Linked list tagId in post points to a linked list in tag_assoc, the application must traverse the list until flink=0 post: id, content, ownerId, date, tagId, notesId tag_assoc: id, tagId, ownerId, flink tag: id, name, notesId Method 2. Denormalization tags is simply a VARCHAR or TEXT field containing a tab delimited array of tagId:ownerId. It cannot be a fixed size. post: id, content, ownerId, date, tags, notesId tag: id, name, notesId Method 3. Toxi (from: http://www.pui.ch/phred/archives/2005/04/tags-database-schemas.html, also same thing here: http://stackoverflow.com/questions/20856/how-do-you-recommend-implementing-tags-or-tagging) post: id, content, ownerId, date, notesId tag_assoc: ownerId, tagId, postId tag: id, name, notesId Method 3 raises the question, how fast will it be to iterate through every single row in tag_assoc? Methods 1 and 2 should be fast for returning tags by post, but for posts by tag, another lookup table must be made. The last thing I have to worry about is optimizing searching tags by name, I have not worked that out yet. I made an ASCII diagram here: http://pastebin.com/f1c4e0e53

  • Best of both worlds: browser and desktop game?

    - by Ricket
    When considering a platform for a game, I've decided on multi-platform (Win/Lin/Mac) but can't make up my mind as far as browser vs. desktop. As I'm not all too far in development, and now having second thoughts, I'd like your opinion! Browser-based games using Java applets: market penetration is reasonably high (for version 6, it's somewhere around 60% I believe?) using JOGL, 3D performance/quality is decent; certainly good enough to render the crappy 3D graphics that I make there's the (small?) possibility of porting something to Android great for an audience of gamers who switch computers often; can sit down at any computer, load a webpage and play it also great for casual gamers or less knowledgeable gamers who are quite happy with playing games in a browser but don't want to install more things to their computer written in a high-level language which I am more familiar with than C++ - but at the same time, I would like to improve my skills with C++ as it is probably where I am headed in the game industry once I get out of school... easier update process: reload the page. Desktop games using good ol' C++ and OpenGL 100% market penetration, assuming complete cross-platform; however, that number reduces when you consider how many people will go through downloading and installing an executable compared to just browsing to a webpage and hitting "yes" to a security warning. more trouble to maintain the cross-platform; but again, for learning purposes I would embrace the challenge and the knowledge I would gain better performance all around true full screen, whereas browser games often struggle with smooth full screen graphics (especially on Linux, in my experience) can take advantage of distribution platforms such as Steam more likely to be considered a "real" game, whereas browser and Java games are often dismissed as not being real games and therefore not played by "hardcore gamers" installer can be large; don't have to worry so much about download times Is there a way to have the best of both worlds? I love Java applets, but I also really like the reasons to write a desktop game. I don't want to constantly port everything between a Java applet project and a C++ project; that would be twice the work! Unity chose to write their own web player plugin. I don't like this, because I am one of the people that will not install their web player for anything, and I don't see myself being able to convince my audience to install a browser plugin. What are my options? Are there other examples out there besides Unity, of games that have browser and desktop versions? Did I leave out anything in the pro/con lists above?

  • Performing full screen grab in windows

    - by Steven Lu
    I am working an idea that involves getting a full capture of the screen including windows and apps, analyzing it, and then drawing items back onto the screen, as an overlay. I want to learn image processing techniques and I could get lots of data to work with if I can directly access the Windows screen. I could use this to build automation tools the likes of which have never been seen before. More on that later. I have full screen capture working for the most part. HWND hwind = GetDesktopWindow(); HDC hdc = GetDC(hwind); int resx = GetSystemMetrics(SM_CXSCREEN); int resy = GetSystemMetrics(SM_CYSCREEN); int BitsPerPixel = GetDeviceCaps(hdc,BITSPIXEL); HDC hdc2 = CreateCompatibleDC(hdc); BITMAPINFO info; info.bmiHeader.biSize = sizeof(BITMAPINFOHEADER); info.bmiHeader.biWidth = resx; info.bmiHeader.biHeight = resy; info.bmiHeader.biPlanes = 1; info.bmiHeader.biBitCount = BitsPerPixel; info.bmiHeader.biCompression = BI_RGB; void *data; hbitmap = CreateDIBSection(hdc2,&info,DIB_RGB_COLORS,(void**)&data,0,0); SelectObject(hdc2,hbitmap); Once this is done, I can call this repeatedly: BitBlt(hdc2,0,0,resx,resy,hdc,0,0,SRCCOPY); The cleanup code (I have no idea if this is correct): DeleteObject(hbitmap); ReleaseDC(hwind,hdc); if (hdc2) { DeleteDC(hdc2); } Every time BitBlt is called it grabs the screen and saves it in memory I can access thru data. Performance is somewhat satisfactory. BitBlt executes in 50 milliseconds (sometimes as low as 33ms) at 1920x1200x32. What surprises me is that when I switch display mode to 16 bit, 1920x1200x16, either through my graphics settings beforehand, or by using ChangeDisplaySettings, I get a massively improved screen grab time between 1ms and 2ms, which cannot be explained by the factor of two reduction in bit-depth. Using CreateDIBSection (as above) offers a significant speed up when in 16-bit mode, compared to if I set up with CreateCompatibleBitmap (6-7ms/f). Does anybody know why dropping to 16bit causes such a speed increase? Is there any hope for me to grab 32bit at such speeds? if not for the color depth, but for not forcing a change of screen buffer modes and the awful flickering.

  • How to populate GridView if Internet not available but images already cached to SD Card

    - by Sophie
    Hello I am writing an Application in which i am parsing JSON Images and then caching into SD Card. What I want to do ? I want to load images into GridView from JSON (by caching images into SD Card), and wanna populate GridView (no matter Internet available or not) once images already downloaded into SD Card. What I am getting ? I am able to cache images into SD Card, also to populate GridView, but not able to show images into GridView (if Internet not available) but images cached into SD Card @Override public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { myGridView = inflater.inflate(R.layout.fragment_church_grid, container, false); if (isNetworkAvailable()) { new DownloadJSON().execute(); } else { Toast.makeText(getActivity(), "Internet not available !", Toast.LENGTH_LONG).show(); } return myGridView ; } private boolean isNetworkAvailable() { ConnectivityManager cm = (ConnectivityManager) getActivity().getSystemService(Context.CONNECTIVITY_SERVICE); NetworkInfo info = cm.getActiveNetworkInfo(); return (info != null); } // DownloadJSON AsyncTask private class DownloadJSON extends AsyncTask<Void, Void, Void> { @Override protected void onPreExecute() { super.onPreExecute(); // Create a progressdialog mProgressDialog = new ProgressDialog(getActivity()); // Set progressdialog title mProgressDialog.setTitle("Church Application"); // Set progressdialog message mProgressDialog.setMessage("Loading Images..."); mProgressDialog.setIndeterminate(false); // Show progressdialog mProgressDialog.show(); } @Override protected Void doInBackground(Void... params) { // Create an array arraylist = new ArrayList<HashMap<String, String>>(); // Retrieve JSON Objects from the given URL address jsonobject = JSONfunctions .getJSONfromURL("http://snapoodle.com/APIS/android/feed.php"); try { // Locate the array name in JSON jsonarray = jsonobject.getJSONArray("print"); for (int i = 0; i < jsonarray.length(); i++) { HashMap<String, String> map = new HashMap<String, String>(); jsonobject = jsonarray.getJSONObject(i); // Retrive JSON Objects map.put("saved_location", jsonobject.getString("saved_location")); // Set the JSON Objects into the array arraylist.add(map); } } catch (JSONException e) { Log.e("Error", e.getMessage()); e.printStackTrace(); } return null; } @Override protected void onPostExecute(Void args) { // Locate the listview in listview_main.xml listview = (GridView) shriRamView.findViewById(R.id.listview); // Pass the results into ListViewAdapter.java adapter = new ChurchImagesAdapter(getActivity(), arraylist); // Set the adapter to the ListView listview.setAdapter(adapter); // Close the progressdialog mProgressDialog.dismiss(); } } }

  • Recursion problem; completely lost

    - by timeNomad
    So I've been trying to solve this assignment whole day, just can't get it. The following function accepts 2 strings, the 2nd (not 1st) possibly containing *'s (asterisks). An * is a replacement for a string (empty, 1 char or more), it can appear appear (only in s2) once, twice, more or not at all, it cannot be adjacent to another * (ab**c), no need to check that. public static boolean samePattern(String s1, String s2) It returns true if strings are of the same pattern. It must be recursive, not use any loops, static & global variables. Can use local variables & method overloading. Can use only these methods: charAt(i), substring(i), substring(i, j), length(). Examples: 1: TheExamIsEasy; 2: "The*xamIs*y" --- true 1: TheExamIsEasy; 2: "Th*mIsEasy*" --- true 1: TheExamIsEasy; 2: "*" --- true 1: TheExamIsEasy; 2: "TheExamIsEasy" --- true 1: TheExamIsEasy; 2: "The*IsHard" --- FALSE I tried comparing the the chars one by one using charAt until an asterisk is encountered, then check if the asterisk is an empty one by comparing is successive char (i+1) with the char of s1 at position i, if true -- continue recursion with i+1 as counter for s2 & i as counter for s1; if false -- continue recursion with i+1 as counters for both. Continue this until another asterisk is found or end of string. I dunno, my brain loses track of things, can't concentrate, any pointers / hints? Am I in the right direction? Also, it's been told that a backtracking technique is to be used to solve this. My code so far (doesn't do the job, even theoretically): public static boolean samePattern(String s1, String s2) { if (s1.equals(s2) || s2 == "*") { return true; } return samePattern(s1, s2, 1); } public static boolean samePattern(String s1, String s2, int i) { if (s1.equals(s2)) return true; if (i == s2.length() - 1) // No *'s found -- not same pattern. return false; if (s1.substring(0, i).equals(s2.substring(0, i))) samePattern(s1, s2, i+1); else if (s2.charAt(i-1) == '*') samePattern(s1.substring(0, i-1), s2.substring(0, i), 1); // new smaller strings. else samePattern(s1.substring(1), s2, i); }

  • How to resize the UIView when CGAffineTransformIdentity

    - by Gowtham
    I am doing an app which has a feature to rotate and re size a view. i have implemented this feature but i do face an issue. My problem The View wil be resized when dragging its four corners, after resizing it i can rotate the view in both directions. Once the rotation is done, if i try again to resize the view by dragging its corner, the view's size gone to unpredictable value and its moving all around the screen. I googled lot finally i got the following solution The frame property is undefined when transform != CGAffineTransformIdentity, as per the docs on UIView I saw one app which has implemented the feature exactly what i wish to implement. How can i resize the UIView after rotation of UIView My code for resize the view Touches Began - (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event{ UITouch *touch = [[event allTouches] anyObject]; NSLog(@"[touch view]:::%@",[touch view]); touchStart = [[touches anyObject] locationInView:testVw]; isResizingLR = (testVw.bounds.size.width - touchStart.x < kResizeThumbSize && testVw.bounds.size.height - touchStart.y < kResizeThumbSize); isResizingUL = (touchStart.x <kResizeThumbSize && touchStart.y <kResizeThumbSize); isResizingUR = (testVw.bounds.size.width-touchStart.x < kResizeThumbSize && touchStart.y<kResizeThumbSize); isResizingLL = (touchStart.x <kResizeThumbSize && testVw.bounds.size.height -touchStart.y <kResizeThumbSize); } Touches Moved - (void)touchesMoved:(NSSet *)touches withEvent:(UIEvent *)event{ CGPoint touchPoint = [[touches anyObject] locationInView:testVw]; CGPoint previous=[[touches anyObject]previousLocationInView:testVw]; float deltaWidth = touchPoint.x-previous.x; float deltaHeight = touchPoint.y-previous.y; NSLog(@"CVTM:%@",NSStringFromCGRect(testVw.frame)); if (isResizingLR) { testVw.frame = CGRectMake(testVw.frame.origin.x, testVw.frame.origin.y,touchPoint.x + deltaWidth, touchPoint.y + deltaWidth); } if (isResizingUL) { testVw.frame = CGRectMake(testVw.frame.origin.x + deltaWidth, testVw.frame.origin.y + deltaHeight, testVw.frame.size.width - deltaWidth, testVw.frame.size.height - deltaHeight); } if (isResizingUR) { testVw.frame = CGRectMake(testVw.frame.origin.x ,testVw.frame.origin.y + deltaHeight, testVw.frame.size.width + deltaWidth, testVw.frame.size.height - deltaHeight); } if (isResizingLL) { testVw.frame = CGRectMake(testVw.frame.origin.x + deltaWidth ,testVw.frame.origin.y , testVw.frame.size.width - deltaWidth, testVw.frame.size.height + deltaHeight); } if (!isResizingUL && !isResizingLR && !isResizingUR && !isResizingLL) { testVw.center = CGPointMake(testVw.center.x + touchPoint.x - touchStart.x,testVw.center.y + touchPoint.y - touchStart.y); } }

Could this code be improved further? I don't seem to be able to get the "transfer" effect to work correctly in a modal. I added: , close: function() { $(this).effect("transfer",{ to: $("#user-form") }, 1500); } to the $( "#form" ).dialog({ How would you go about in getting the "transfer" to work nicely when you open and close the dialog box?

  • Why doesn't TextBlock databinding call ToString() on a property whose compile-time type is an interf

    - by Jay
    This started with weird behaviour that I thought was tied to my implementation of ToString(), and I asked this question: http://stackoverflow.com/questions/2916068/why-wont-wpf-databindings-show-text-when-tostring-has-a-collaborating-object It turns out to have nothing to do with collaborators and is reproducible. When I bind Label.Content to a property of the DataContext that is declared as an interface type, ToString() is called on the runtime object and the label displays the result. When I bind TextBlock.Text to the same property, ToString() is never called and nothing is displayed. But, if I change the declared property to a concrete implementation of the interface, it works as expected. Is this somehow by design? If so, any idea why? To reproduce: Create a new WPF Application (.NET 3.5 SP1) Add the following classes: public interface IFoo { string foo_part1 { get; set; } string foo_part2 { get; set; } } public class Foo : IFoo { public string foo_part1 { get; set; } public string foo_part2 { get; set; } public override string ToString() { return foo_part1 + " - " + foo_part2; } } public class Bar { public IFoo foo { get { return new Foo {foo_part1 = "first", foo_part2 = "second"}; } } } Set the XAML of Window1 to: <Window x:Class="WpfApplication1.Window1" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Title="Window1" Height="300" Width="300"> <StackPanel> <Label Content="{Binding foo, Mode=Default}"/> <TextBlock Text="{Binding foo, Mode=Default}"/> </StackPanel> </Window> in Window1.xaml.cs: public partial class Window1 : Window { public Window1() { InitializeComponent(); DataContext = new Bar(); } } When you run this application, you'll see the text only once (at the top, in the label). If you change the type of foo property on Bar class to Foo (instead of IFoo) and run the application again, you'll see the text in both controls.

  • Jquery $.post and PHP - Prevent the ability to use script outside of main website.

    - by Tim
    I have a PHP script setup using Jquery $.post which would return a response or do an action within the targeted .php file within $.post. Eg. My page has a form where you type in your Name. Once you hit the submit form button, $.post is called and sends the entered Name field value into "mywebsite.xyz/folder/ajaxscript.php" If a user was to visit "mywebsite.xyz/folder/ajaxscript.php" directly and somehow POST the data to the script, the script would return a response / do an action, based on the submitted POST data. The problem is, I don't want others to be able to periodically "call" an action or request a response from my website without using the website directly. Theoretically, right now you could determine what Name values my website allows without even visiting it, or you could call an action without going through the website, by simply visiting "mywebsite.xyz/folder/ajaxscript.php" So, what measures can I take to prevent this from happening? So far my idea is to ensure that it is a $_POST and not a $_GET - so they cannot manually enter it into the browser, but they could still post data to the script... Another measure is to apply a session key that expires, and is only valid for X amount of visits until they revisit the website. ~ Or, just have a daily "code" that changes and they'd need to grab this code from the website each day to keep their direct access to the script working (eg. I pass the daily "code" into each post request. I then check that code matches in the ajax php script.) However, even with these meaures, they will STILL have access to the scripts so long as they know how to POST the data, and also get the new code each day. Also, having a daily code requirement will cause issues when visiting the site at midnight (12:00am) as the code will change and the script will break for someone who is on the website trying to call the script, with the invalid code being passed still. I have attempted using .htaccess however using: order allow,deny deny from all Prevents legitimate access, and I'd have to add an exception so the website's IP is allowed to access it.. which is a hassle to update I think. Although, if it's the only legitimate solution I guess I'll have to. If I need to be more clear please let me know.

  • Using pointers, references, handles to generic datatypes, as generic and flexible as possible

    - by Patrick
    In my application I have lots of different data types, e.g. Car, Bicycle, Person, ... (they're actually other data types, but this is just for the example). Since I also have quite some 'generic' code in my application, and the application was originally written in C, pointers to Car, Bicycle, Person, ... are often passed as void-pointers to these generic modules, together with an identification of the type, like this: Car myCar; ShowNiceDialog ((void *)&myCar, DATATYPE_CAR); The 'ShowNiceDialog' method now uses meta-information (functions that map DATATYPE_CAR to interfaces to get the actual data out of Car) to get information of the car, based on the given data type. That way, the generic logic only has to be written once, and not every time again for every new data type. Of course, in C++ you could make this much easier by using a common root class, like this class RootClass { public: string getName() const = 0; }; class Car : public RootClass { ... }; void ShowNiceDialog (RootClass *root); The problem is that in some cases, we don't want to store the data type in a class, but in a totally different format to save memory. In some cases we have hundreds of millions of instances that we need to manage in the application, and we don't want to make a full class for every instance. Suppose we have a data type with 2 characteristics: A quantity (double, 8 bytes) A boolean (1 byte) Although we only need 9 bytes to store this information, putting it in a class means that we need at least 16 bytes (because of the padding), and with the v-pointer we possibly even need 24 bytes. For hundreds of millions of instances, every byte counts (I have a 64-bit variant of the application and in some cases it needs 6 GB of memory). The void-pointer approach has the advantage that we can almost encode anything in a void-pointer and decide how to use it if we want information from it (use it as a real pointer, as an index, ...), but at the cost of type-safety. Templated solutions don't help since the generic logic forms quite a big part of the application, and we don't want to templatize all this. Additionally, the data model can be extended at run time, which also means that templates won't help. Are there better (and type-safer) ways to handle this than a void-pointer? Any references to frameworks, whitepapers, research material regarding this?
