  • Unable to retrieve data, mysql php pdo

    - by Kyle Hudson
    Hi, I have an issue, i cannot get any results from mysql on a production box but can on a development box, we use PHP 5.3 with MySQL (pdo). $sd = $this->dbh->quote($sd); $si_sql = "SELECT COUNT(*) FROM tbl_wl_data WHERE (site_domain = $sd OR siteDomainMasked = $sd);"; if($this->dbh->query($si_sql)->rowCount() > 0) { //gets to here, just doesnt get through the loop $sql = "SELECT pk_aid, site_name, site_css, site_img_sw, supportPhone FROM tbl_wl_data WHERE (site_domain = $sd OR siteDomainMasked = $sd);"; foreach($this->dbh->query($sql) as $wlsd) { //-- fails here if($wlsd['wl_status'] != '1') { require "_domainDisabled.php"; exit; } $this->pk_aid = $wlsd['pk_aid']; $this->siteTitle = $wlsd['site_name']; $this->siteCSS = $wlsd['site_css']; $this->siteImage = $wlsd['site_img_sw']; $this->siteSupportPhone = $wlsd['supportPhone']; } } else { throw new ERR_SITE_NOT_LINKED; } It just doesnt seem to get into the loopk, i ran the query in navicat and it returns the data. Really confused :S

  • Retrieve POST data without knowing exact number of fields

    - by James
    Hi all! I'm creating an online poll from scratch which will be held in a database. I'm working on getting a system set up so someone can create a new poll. I will be having the user fill out a simple HTML form with the Questions and Answers (there may be several answers). The user will be able to add multiple questions and multiple answers for each question. As the total number of questions and answers will be decided by the user, I need to create some clever PHP to cater for this - however many there are. When dealing with a static number of questions, it's simple. But I'm having trouble thinking of a way to get all the POST data into individual PHP variables so I can process them. I was thinking of using a foreach loop, anyone got any ideas? Sorry for the long winded description! If anyone needs anything clarified, I'd be happy to do so. My problem is that I can't get my head around how to deal with the POST values when I don't know exactly which element of the array will contain what. If things were static with a set number of questions and answers, I'd know $_POST[0] was Question1, etc Thank you! =)

  • This program isn't asking for the predetermined 5 numbers from the array?

    - by user1801781
    Okay, so this question is difficult to state. I'm a beginner at C++, and I rarely run into problems with these simple assignments, but something is majorly wrong here and I cannot identify it. I've been trying for hours. This program is supposed to read 5 numbers from an array that the user enters, and then print the largest one. (I know it's easier to just write a for-loop, but our professor wanted us to call a function). The only problem is that instead of asking for 5 numbers, it asks for 2. It works other than that, I JUST NEED IT TO ASK FOR 5 NUMBERS. haha. Your input would be greatly appreciated. I aspire to be a programmer one day, so don't be afraid to go harsh on me. #include <iostream> using namespace std; int largest_number(int score[], int max) { for (int i=1; i<5; i++) { cin >> score[i]; if(score[i] > max) max=score[i]; return (max); } } int main () { int score[5], max, z; cout << "Enter 5 numbers: " <<endl; cin >> score[0]; max = score[0]; z = largest_number(score, max); cout << "The largest number is: " << z <<endl; system("pause"); return 0; }

  • Basic Application Organization + Publishing (.NET 4.0)

    - by keynesiancross
    Hi all, I'm trying to figure out the best way to keep my program organized. Currently I have many class files in one project file, but some of these classes do things that are very different, and some I would like to expose to other applications in the future. One thought I had to organizing my application was to create multiple project files, with one "Main" project, which would interact with all the other projects and their relevant classes as needed. Does this make sense? I was wondering if anyone had any suggestions in regards to using multiple project files in one solution (and how do you create something like this?), and if it makes sense to have multiple namespaces in one solution... Cheers ----Edit Below---- Sorry, my fault. Currently my program is all in one console project. Within this project I have several classes, some of which basically launch a BackgroundWorker and run an endless loop pulling data. The BackgroundWorker then passes this data back to the main business logic as needed. I'm hoping to seperate this data pull material (including the background worker material) into one project file, and the rest of the business logic into another project file. The projects will have to pass objects between eachother though (the data to the main business logic, and the business logic will pass startup parameteres to the dataPull project)... Hopefully this adds a bit more detail.

  • Why does my Perl TCP server script hang with many TCP connections?

    - by viraptor
    I've got a strange issue with a server accepting TCP connections. Even though there are normally some processes waiting, at some volume of connections it hangs. Long version: The server is written in Perl and binds a $srv socket with the reuse flag and listen == 5. Afterwards, it forks into 10 processes with a loop of $clt=$srv->accept(); do_processing($clt); $clt->shutdown(2); The client written in C is also very simple - it sends some lines, then receives all lines available and does a shutdown(sockfd, 2); There's nothing async going on and at the end both send and receive queues are empty (as reported by netstat). Connections last only ~20ms. All clients behave the same way, are the same implementation, etc. Now let's say I'm accepting X connections from client 1 and another X from client 2. Processes still report that they're idle all the time. If I add another X connections from client 3, suddenly the server processes start hanging just after accepting. The first blocking thing they do after accept(); is while (<$clt>) ... - but they don't get any data (on the first try already). Suddenly all 10 processes are in this state and do not stop waiting. On strace, the server processes seem to hang on read(), which makes sense. There are loads of connections in TIME_WAIT state belonging to that server (~100 when the problem starts to manifest), but this might be a red herring. What could be happening here?

  • how to create a array of labelfields

    - by sheetal_r oswal
    I have 'n' number of data which has to be added to a label field which in turn has to be added to hfm.I am setting the single data in to label field as : final LabelField desc = new LabelField("", LabelField.FOCUSABLE); final LabelField desc1 = new LabelField("", LabelField.FOCUSABLE); Vector data = (Vector) listEvent.get(keys); for (int i = 0; i < data.size(); i++) { EventData ee = (EventData) data.elementAt(i); String Summary= ee.getSummary(); if (time.getText().equals(sTime)) { desc.setText(Summary); } else{ desc1.setText(Summary); } } HorizontalFieldManager horizontalFieldManager_left18 = new HorizontalFieldManager() { horizontalFieldManager_left18.add(desc1); vfm.add(horizontalFieldManager_left18); vfm.add(new SeparatorField()); HorizontalFieldManager horizontalFieldManager_left17 = new HorizontalFieldManager() { horizontalFieldManager_left17.add(desc); vfm.add(horizontalFieldManager_left17); vfm.add(new SeparatorField()); In the above code i loop over vector and set the data into labelfield and adding the label to hfm later. Now the case is the vector data has more than one summary data,and the data is getting overridden in labelfield,i need to keep 'n' number of summary data into lablefield and add to new hfm.

  • Replacing text with variables

    - by Steve
    I have to send out letters to certain clients and I have a standard letter that I need to use. I want to replace some of the text inside the body of the message with variables. Here is my maturity_letter models.py class MaturityLetter(models.Model): default = models.BooleanField(default=False, blank=True) body = models.TextField(blank=True) footer = models.TextField(blank=True) Now the body has a value of this: Dear [primary-firstname], AN IMPORTANT REMINDER… You have a [product] that is maturing on [maturity_date] with [financial institution]. etc Now I would like to replace everything in brackets with my template variables. This is what I have in my views.py so far: context = {} if request.POST: start_form = MaturityLetterSetupForm(request.POST) if start_form.is_valid(): agent = request.session['agent'] start_date = start_form.cleaned_data['start_date'] end_date = start_form.cleaned_data['end_date'] investments = Investment.objects.all().filter(maturity_date__range=(start_date, end_date), plan__profile__agent=agent).order_by('maturity_date') inv_form = MaturityLetterInvestments(investments, request.POST) if inv_form.is_valid(): sel_inv = inv_form.cleaned_data['investments'] context['sel_inv'] = sel_inv maturity_letter = MaturityLetter.objects.get(id=1) context['mat_letter'] = maturity_letter context['inv_form'] = inv_form context['agent'] = agent context['show_report'] = True Now if I loop through the sel_inv I get access to sel_inv.maturity_date, etc but I am lost in how to replace the text. On my template, all I have so far is: {% if show_letter %} {{ mat_letter.body }} <br/> {{ mat_letter.footer }} {% endif %} Much appreciated.

  • Major JQuery bug on IE not reproducible - What can i do in this situation to solve this bug?

    - by ming yeow
    I am hoping to get some help on this issue. Some users on IE have been reporting this javascript issue, but I have been unable to re-produce it. In essence, for some class of windows IE users, the game doesn't work (or $.ajax() is not working). What I know: I swapped out an ajax call (ajax_init_trainer) and used a standard link with some request parameters to do the initialization and ppl seemed to get passed the problem until they hit the next ajax call. I read somewhere that IE does crazy caching so you need to make the urls unique, which is why i added the _requestno parameter. However, setting the cache:false is said to also do this. This didn't fix it for someone who was complaining. function done(res, status) { var data = JSON.parse(res.responseText); hide_loading(); if (status == "success") { window.location.href="/bamo/battle/?{{ fb_sig}}"; } else { display_alert("Problem!",data.msg,$("#notifications")); } }; $(".monster_select_class").click(function() { $(this).attr("src","{{MEDIA_URL}}/bamo/button_select_click.png"); monster_class = $(this).attr("monster_class"); monster_type = $(this).attr("monster_type"); ajax_init_trainer(monster_class,monster_type); }); function ajax_init_trainer(trainer_class,monster_type) { var data = {trainer_class:trainer_class,monster_type:monster_type}; var d = new Date(); var args = { type:"POST",url:"/bamo/api/init_trainer/?_requestno="+d.getTime(),data:data,contentType:"application/json;", dataType: "json",cache:false,complete:done}; $.ajax(args); return false; };

  • How do I daemonize an arbitrary script in unix?

    - by dreeves
    I'd like a daemonizer that can turn an arbitrary, generic script or command into a daemon. There are two common cases I'd like to deal with: I have a script that should run forever. If it ever dies (or on reboot), restart it. Don't let there ever be two copies running at once (detect if a copy is already running and don't launch it in that case). I have a simple script or command line command that I'd like to keep executing repeatedly forever (with a short pause between runs). Again, don't allow two copies of the script to ever be running at once. Of course it's trivial to write a "while(true)" loop around the script in case 2 and then apply a solution for case 1, but a more general solution will just solve case 2 directly since that applies to the script in case 1 as well (you may just want a shorter or no pause if the script is not intended to ever die (of course if the script really does never die then the pause doesn't actually matter)). Note that the solution should not involve, say, adding file-locking code or PID recording to the existing scripts. More specifically, I'd like a program "daemonize" that I can run like % daemonize myscript arg1 arg2 or, for example, % daemonize 'echo `date` >> /tmp/times.txt' which would keep a growing list of dates appended to times.txt. (Note that if the argument(s) to daemonize is a script that runs forever as in case 1 above, then daemonize will still do the right thing, restarting it when necessary.) I could then put a command like above in my .login and/or cron it hourly or minutely (depending on how worried I was about it dying unexpectedly). NB: The daemonize script will need to remember the command string it is daemonizing so that if the same command string is daemonized again it does not launch a second copy. Also, the solution should ideally work on both OS X and linux but solutions for one or the other are welcome. (If I'm thinking of this all wrong or there are quick-and-dirty partial solutions, I'd love to hear that too.)

  • Why does the onclick function run on onclick, but not when I call it manually?

    - by Codemonkey
    This is my code // Register onclick var old_onclick = link.onclick; link.onclick = function() { astr_track_action(param); if(typeof(old_onclick) == "function") old_onclick(); } And this is the html <a onclick="alert('hello!');" href="http://www.google.com?acme=link&foo=bar">To google!</a> When I click the link, the alert pops up. But when I override the onclick with my JS code, the alert does not pop up. Any ideas? Edit: I just want to add, I have debugged and confirmed that old_onclick() is run, but no alert message shows up. Edit: Here is the full code from the loop start. I don't see how it's relevant, but it was requested: for(var i = 0; i < document.links.length; i++) { var link = document.links[i]; var eventlink = link.href.split("acme="); if(eventlink.length > 1) { var param = eventlink[1].split("&")[0]; var newlink = link.href; // Register onclick var old_onclick = link.onclick; link.onclick = function() { astr_track_action(param); if(typeof(old_onclick) == "function") old_onclick(); }

  • How do I access a <form> that is not the master page <form>?

    - by VBCSharp
    Winforms developer converting to web developer. I know the part about the Master Page having the tag, what is not clear is if I can or can not have another in one of my content pages. I have been seeing both answers doing searches. I see yes you can if only one has runat=server. The thing is I have a that contains several radio buttons on a web page that has a master page. I have a .js file that has a function if I send the name into it, it will loop thru the controls in the form to see which one is selected and return the desired date horizon(MTD, QTD, YTD, etc.). When I run this on a non master page web page it works fine. However, when I run on a web page that has a master page I can't seem to get to the element. I tried getElementByID, I tried looping through the page elements, etc. Maybe I am going about this incorrectly and I hope someone can straighten me out. Here is the code from my .js file that may help explain what I am trying to do a little better. var frmDateRanges = document.getElementById(formFieldName); var chosen; var len = frmDateRanges.DateRanges.length; for(i=0;i<len;i++) { if(frmDateRanges.DateRanges[i].checked) { chosen = frmDateRanges.DateRanges[i].value; } } where formFieldName is an arguement that is passed into the function and DateRanges is the name value given to the radio buttons. In the button I call this function I have: onclick ="FunctionCall('frmDateRanges')" FunctionCall is just for description purposes, 'frmDateRanges' is the name and id given to the form action="" Thanks for the help as I am stumped at this point. If there is a better way to do this please let me know that as well.

  • How to access individual items in Android GridView?

    - by source.rar
    Hi, I'm trying to create a game with a 9x9 grid with GridView. Each item in the grid is a TextView. I am able to set the initial values of each item in the grid within the getView() method to "0", however I want to change the value of each grid individually after this but have been unable to do so. I tried adding an update() function in my extended GridAdapter class that takes a position and a number to update at that position but this doesnt seem to be working. public void update(int position, int number) { TextView cell; cell = (TextView) getItem(position); if (cell != null) { cell.setText(Integer.toString(number)); } } Doe anyone know how this can be achieved? Here's the whole GridAdapter class in case require, public class SudokuGridAdapter extends BaseAdapter { private Context myContext; private TextView[] myCells; public SudokuGridAdapter(Context c) { myContext = c; myCells = new TextView[9*9]; } @Override public int getCount() { // TODO Auto-generated method stub return 9*9; } @Override public Object getItem(int position) { return myCells[position]; } @Override public long getItemId(int position) { // TODO Auto-generated method stub return 0; } @Override public View getView(int position, View convertView, ViewGroup parent) { TextView cell; if (myCells[position] == null) { cell = myCells[position] = new TextView(myContext); cell.setText("0"); } else { cell = myCells[position]; } return cell; } public void update(int position, int number) { TextView cell; cell = (TextView) getItem(position); if (cell != null) { cell.setText(Integer.toString(number)); } } }

  • Multithreading: Read from / write to a pipe

    - by Tero Jokinen
    I write some data to a pipe - possibly lots of data and at random intervals. How to read the data from the pipe? Is this ok: in the main thread (current process) create two more threads (2, 3) the second thread writes sometimes to the pipe (and flush-es the pipe?) the 3rd thread has infinite loop which reads the pipe (and then sleeps for some time) Is this so far correct? Now, there are a few thing I don't understand: do I have to lock (mutex?) the pipe on write? IIRC, when writing to pipe and its buffer gets full, the write end will block until I read the already written data, right? How to check for read data in the pipe, not too often, not too rarely? So that the second thread wont block? Is there something like select for pipes? It is possible to set the pipe to unbuffered more or I have to flush it regularly - which one is better? Should I create one more thread, just for flushing the pipe after write? Because flush blocks as well, when the buffer is full, right? I just don't want the 1st and 2nd thread to block.... [Edit] Sorry, I thought the question is platform agnostic but just in case: I'm looking at this from Win32 perspective, possibly MinGW C...

  • UITableViewCell: how to verify the kind of accessoryType in all cells?

    - by R31n4ld0_
    Hello, Guys. I have a UITableView in that some cells are marked with UITableViewCellAccessoryCheckmark at the initialization of the view. When the user selects another row, I have to check if the maximum number of selected rows was achieved before. To do that, I used the code bellow: - (NSInteger)tableView:(UITableView *)tableView numberOfSelectedRowsInSection:(NSInteger)section{ NSInteger numberOfRows = [self tableView:tableView numberOfRowsInSection:section]; NSInteger numberOfSelectedRows = 0; for (int i = 0; i < numberOfRows; i++) { UITableViewCell *otherCell = [tableView cellForRowAtIndexPath:[NSIndexPath indexPathForRow:i inSection:section]]; if (otherCell.accessoryType == UITableViewCellAccessoryCheckmark) { numberOfSelectedRows++; } } return numberOfSelectedRows; } If my number of rows is, as example, 20, the variable numberOfRows is setted correctly with 20. Lets say that 13 rows already are marked with UITableViewCellAccessoryCheckmark. So, numberOfSelectedRows should be 13 after the loop, but only the marked and VISIBLE cells are considered. So, if I have 9 cells showed and 7 are marked, the numberOfSelectedRows returns 7 instead of 13 (but the for iterate 20 times, as expected). Is this a correct behavior of UITableView or it is a bug of iPhone simulator? Thanks in advance.

  • CSV Parser works in windows, not linux.

    - by ladookie
    I'm parsing a CSV file that looks like this: E1,E2,E7,E8,,, E2,E1,E3,,,, E3,E2,E8,,, E4,E5,E8,E11,,, I store the first entry in each line in a string, and the rest go in a vector of strings: while (getline(file_input, line)) { stringstream tokenizer; tokenizer << line; getline(tokenizer, roomID, ','); vector<string> aVector; while (getline(tokenizer, adjRoomID, ',')) { if (!adjRoomID.empty()) { aVector.push_back(adjRoomID); } } Room aRoom(roomID, aVector); rooms.addToTail(aRoom); } In windows this works fine, however in Linux the first entry of each vector mysteriously loses the first character. For Example in the first iteration through the while loop: roomID would be E1 and aVector would be 2 E7 E8 then the second iteration: roomID would be E2 and aVector would be 1 E3 Notice the missing E's in the first entry of aVector. when I put in some debugging code it appears that it is initially being stored correctly in the vector, but then something overwrites it. Kudos to whoever figures this one out. Seems bizarre to me. rooms is declared as such: DLList<Room> rooms where DLList stands for Doubly-Linked list.

    I have been doing a simple jquery data() test. However it is returning undefined. It works on jsfiddle though (http://jsfiddle.net/yrCdj/).

  • Is safe ( documented behaviour? ) to delete the domain of an iterator in execution

    - by PoorLuzer
    I wanted to know if is safe ( documented behaviour? ) to delete the domain space of an iterator in execution in Python. Consider the code: import os import sys sampleSpace = [ x*x for x in range( 7 ) ] print sampleSpace for dx in sampleSpace: print str( dx ) if dx == 1: del sampleSpace[ 1 ] del sampleSpace[ 3 ] elif dx == 25: del sampleSpace[ -1 ] print sampleSpace 'sampleSpace' is what I call 'the domain space of an iterator' ( if there is a more appropriate word/phrase, lemme know ). What I am doing is deleting values from it while the iterator 'dx' is running through it. Here is what I expect from the code : Iteration versus element being pointed to (*): 0: [*0, 1, 4, 9, 16, 25, 36] 1: [0, *1, 4, 9, 16, 25, 36] ( delete 2nd and 5th element after this iteration ) 2: [0, 4, *9, 25, 36] 3: [0, 4, 9, *25, 36] ( delete -1th element after this iteration ) 4: [0, 4, 9, 25*] ( as the iterator points to nothing/end of list, the loop terminates ) .. and here is what I get: [0, 1, 4, 9, 16, 25, 36] 0 1 9 25 [0, 4, 9, 25] As you can see - what I expect is what I get - which is contrary to the behaviour I have had from other languages in such a scenario. Hence - I wanted to ask you if there is some rule like "the iterator becomes invalid if you mutate its space during iteration" in Python? Is it safe ( documented behaviour? ) in Python to do stuff like this?

  • How to get a category listing from Magento?

    - by alex
    I want to create a page in Magento that shows a visual representation of the categories.. example CATEGORY product 1 product 2 ANOTHER CATEGORY product 3 My problem is, their database is organised very differently to what I've seen in the past. They have tables dedicated to data types like varchar, int, etc. I assume this is for performance or similiar. I haven't found a way to use MySQL to query the database and get a list of categories. I'd then like to match these categories to products, to get a listing of products for each category. Unfortunately Magento seems to make this very difficult. Also I have not found a method that will work from within a page block.. I have created showcase.phtml and put it in the XML layout and it displays and runs it's PHP code. I was hoping for something easy like looping through $this-getAllCategories(); and then a nested loop inside with something like $category-getChildProducts(); Can anyone help me? Thank you!

  • Looking for an appropriate design pattern

    - by user1066015
    I have a game that tracks user stats after every match, such as how far they travelled, how many times they attacked, how far they fell, etc, and my current implementations looks somewhat as follows (simplified version): Class Player{ int id; public Player(){ int id = Math.random()*100000; PlayerData.players.put(id,new PlayerData()); } public void jump(){ //Logic to make the user jump //... //call the playerManager PlayerManager.jump(this); } public void attack(Player target){ //logic to attack the player //... //call the player manager PlayerManager.attack(this,target); } } Class PlayerData{ public static HashMap<int, PlayerData> players = new HashMap<int,PlayerData>(); int id; int timesJumped; int timesAttacked; } public void incrementJumped(){ timesJumped++; } public void incrementAttacked(){ timesAttacked++; } } Class PlayerManager{ public static void jump(Player player){ players.get(player.getId()).incrementJumped(); } public void incrementAttacked(Player player, Player target){ players.get(player.getId()).incrementAttacked(); } } So I have a PlayerData class which holds all of the statistics, and brings it out of the player class because it isn't part of the player logic. Then I have PlayerManager, which would be on the server, and that controls the interactions between players (a lot of the logic that does that is excluded so I could keep this simple). I put the calls to the PlayerData class in the Manager class because sometimes you have to do certain checks between players, for instance if the attack actually hits, then you increment "attackHits". The main problem (in my opinion, correct me if I'm wrong) is that this is not very extensible. I will have to touch the PlayerData class if I want to keep track of a new stat, by adding methods and fields, and then I have to potentially add more methods to my PlayerManager, so it isn't very modulized. If there is an improvement to this that you would recommend, I would be very appreciative. Thanks.

  • Response time increasing (worsening) over time with consistent load

    - by NJ
    Ok. I know I don't have a lot of information. That is, essentially, the reason for my question. I am building a game using Flash/Flex and Rails on the back-end. Communication between the two is via WebORB. Here is what is happening. When I start the client an operation calls the server every 60 seconds (not much, right?) which results in two database SELECTS and an UPDATE and a resulting response to the client. This repeats every 60 seconds. I deployed a test version on heroku and NewRelic's RPM told me that response time degraded over time. One client with one task every 60 seconds. Over several hours the response time drifted from 150ms to over 900ms in response time. I have been able to reproduce this in my development environment (my Macbook Pro) so it isn't a problem on Heroku's side. I am not doing anything sophisticated (by design) in the server app. An action gets called, gets some data from the database, performs an AR update and then returns a response. No caching, etc. Any thoughts? Anyone? I'd really appreciate it.

  • IDENTITY_INSERT ON inside of cursor does not allow inserted id

    - by Mac
    I am trying to set some id's for a bunch of rows in a database where the id column is an identity. I've created a cursor to loop through the rows and update the ids with incrementing negative numbers (-1,-2,-3 etc). When I updated just one row turning on the IDENTITY_INSERT it worked fine but as soon as I try and use it in a cursor, it throws the following error. Msg 8102, Level 16, State 1, Line 22 Cannot update identity column 'myRowID'. DECLARE @MinId INT; SET @MinId = (SELECT MIN(myRowId) FROM myTable)-1; DECLARE myCursor CURSOR FOR SELECT myRowId FROM dbo.myTable WHERE myRowId > 17095 OPEN myCursor DECLARE @myRowId INT FETCH NEXT FROM myCursor INTO @myRowId WHILE (@@FETCH_STATUS <> -1) BEGIN SET IDENTITY_INSERT dbo.myTable ON; --UPDATE dbo.myTable --SET myRowId = @MinId --WHERE myRowId = @myRowId; PRINT (N'ID: ' + CAST(@myRowId AS VARCHAR(10)) + N' NewID: ' + CAST(@MinId AS VARCHAR(4))); SET @MinId = @MinId - 1; FETCH NEXT FROM myCursor INTO @myRowId END CLOSE myCursor DEALLOCATE myCursor GO SET IDENTITY_INSERT dbo.myTable OFF; GO Does anyone know what I'm doing wrong?

  • Disable home button in android toddler app?

    - by cmerrell
    I've developed and app that is a slide show of pictures which each play a sound when you tap them. It's like a picture book for ages 2-4. The problem is, since android won't let you capture a home button press and essentially disable it, when parents give the phone to their child to play with unattended (brave parent), the child can inadvertenly exit the app and then make calls or otherwise tweak the phone. There are two other apps that currently have a psuedo fix for this issue. The apps are Toddler Lock and ToddlePhone. I've tried contacting the developers of these apps for some guidance but they haven't been willing to disclose anything, which if fine, but does anyone here have any suggestions? It looks like both of those other apps are acting like a home screen replacement app. When you enable the "childproof mode" on those apps the user is prompted to chose and app for the action and the choices are "Launcher, LauncherPro, etc." plus the toddler app. You then have to make the toddler app the default and voila, the phone is "locked" and can only be "unlocked" using a key combination or touching the four corners of the screen, etc. when you "unlock" the phone. your normal home screen app default restored. You don't even have to make the toddler app the default the next time you enable the "childproof mode". I have read that these two apps have problems with Samsung phones and they can cause an an infinite crash-and-restart-loop that requires a factory reset to fix. Obviously this is not the ideal solution to the problem but it looks like the only one availiable at this point. Does anyone have any ideas on how to implement a "childproof mode"?
