• Script to reformat XML file

• surfaceDestroyed called out of turn

  - by Avasulthiris

  I'm currently developing on minimum sdk version 3 (Android 1.5 - cupcake) and I'm having a strange unexplained issue that I have not been able to solve on my own. It is now becoming a rather urgent issue as I've already missed 1 deadline... I'm writing a high-level library to make long term android development easier and quicker. The one specific module has to capture images for a application... I've gotten everything right so far over the last couple months, except this one little thing and I don't know what to do any more: When I use the Camera object and implement a SurfaceHolder.Callback, the methods surfaceCreated() and surfaceChanged() are called one after the other. Then when the activity finishes, surfaceDestroyed() is called. This is how it should be, but when I stick the exact same code in my library (plain Java library that references the Android API - not in an activity), surfaceDestroyed() is called directly after created and changed. As a result - the camera object is closed before I can use it and the application force closes. What a pain. I can't do anything! This method call is controlled by the device.. Why does the surface close for no reason? Even when I post it to run on the activity thread through my own invokeAndWait(Runnable) method, like I do for many other things. I have 5 different working examples of different ways and implementations of capturing images in android but I still get the same issue when I plug it into my library. I don't understand what the difference is. The code is pretty much the same - and I post all the related code to the UI thread so its not a thread handling issue or anything like that. I've rewritten it about 20 times in different ways - same issue every time.. The only other way to approach it that I know of is creating a new Camera and setting it to the VideoView. The android source (c++ native code) however provides no Camera constructor, only an open() method which automatically forwards the camera's state to 'prepared' but I can only set the camera to the VideoView from the 'initialized' state. Pretty silly, I know, but there is no way around it unless I modify the Android library source code haha. not an option! The API does not allow for this method - you are expected to use it like my first example. So essentially - i just need to understand exactly why surfaceDestroyed() is called out of turn and if there is anything I can do to avoid it closing? If i can just understand the exact logic behind it and how it works! The documentation isn't much help! Secondly, if someone knows of any alternative ways to do it, as my second example, but hopefully one which the API actually allows for? haha Thanks guys. I would post code, but its fairly complicated, a couple thousand lines for this specific class and it would probably take a couple days to explain with all the threading and event listeners and what not. I just need help with this 1 single thing. Please let me know if you have any questions.

• Spring Security and the Synchronizer Token J2EE pattern, problem when authentication fails.

  - by dfuse

  Hey, we are using Spring Security 2.0.4. We have a TransactionTokenBean which generates a unique token each POST, the bean is session scoped. The token is used for the duplicate form submission problem (and security). The TransactionTokenBean is called from a Servlet filter. Our problem is the following, after a session timeout occured, when you do a POST in the application Spring Security redirects to the logon page, saving the original request. After logging on again the TransactionTokenBean is created again, since it is session scoped, but then Spring forwards to the originally accessed url, also sending the token that was generated at that time. Since the TransactionTokenBean is created again, the tokens do not match and our filter throws an Exception. I don't quite know how to handle this elegantly, (or for that matter, I can't even fix it with a hack), any ideas? This is the code of the TransactionTokenBean: public class TransactionTokenBean implements Serializable { public static final int TOKEN_LENGTH = 8; private RandomizerBean randomizer; private transient Logger logger; private String expectedToken; public String getUniqueToken() { return expectedToken; } public void init() { resetUniqueToken(); } public final void verifyAndResetUniqueToken(String actualToken) { verifyUniqueToken(actualToken); resetUniqueToken(); } public void resetUniqueToken() { expectedToken = randomizer.getRandomString(TOKEN_LENGTH, RandomizerBean.ALPHANUMERICS); getLogger().debug("reset token to: " + expectedToken); } public void verifyUniqueToken(String actualToken) { if (getLogger().isDebugEnabled()) { getLogger().debug("verifying token. expected=" + expectedToken + ", actual=" + actualToken); } if (expectedToken == null || actualToken == null || !isValidToken(actualToken)) { throw new IllegalArgumentException("missing or invalid transaction token"); } if (!expectedToken.equals(actualToken)) { throw new InvalidTokenException(); } } private boolean isValidToken(String actualToken) { return StringUtils.isAlphanumeric(actualToken); } public void setRandomizer(RandomizerBean randomizer) { this.randomizer = randomizer; } private Logger getLogger() { if (logger == null) { logger = Logger.getLogger(TransactionTokenBean.class); } return logger; } } and this is the Servlet filter (ignore the Ajax stuff): public class SecurityFilter implements Filter { static final String AJAX_TOKEN_PARAM = "ATXTOKEN"; static final String TOKEN_PARAM = "TXTOKEN"; private WebApplicationContext webApplicationContext; private Logger logger = Logger.getLogger(SecurityFilter.class); public void init(FilterConfig config) { setWebApplicationContext(WebApplicationContextUtils.getWebApplicationContext(config.getServletContext())); } public void destroy() { } public void doFilter(ServletRequest req, ServletResponse response, FilterChain chain) throws IOException, ServletException { HttpServletRequest request = (HttpServletRequest) req; if (isPostRequest(request)) { if (isAjaxRequest(request)) { log("verifying token for AJAX request " + request.getRequestURI()); getTransactionTokenBean(true).verifyUniqueToken(request.getParameter(AJAX_TOKEN_PARAM)); } else { log("verifying and resetting token for non-AJAX request " + request.getRequestURI()); getTransactionTokenBean(false).verifyAndResetUniqueToken(request.getParameter(TOKEN_PARAM)); } } chain.doFilter(request, response); } private void log(String line) { if (logger.isDebugEnabled()) { logger.debug(line); } } private boolean isPostRequest(HttpServletRequest request) { return "POST".equals(request.getMethod().toUpperCase()); } private boolean isAjaxRequest(HttpServletRequest request) { return request.getParameter("AJAXREQUEST") != null; } private TransactionTokenBean getTransactionTokenBean(boolean ajax) { return (TransactionTokenBean) webApplicationContext.getBean(ajax ? "ajaxTransactionTokenBean" : "transactionTokenBean"); } void setWebApplicationContext(WebApplicationContext context) { this.webApplicationContext = context; } }

• How to get data from other php scripts

  - by user225269

  I have 2 files, one is used to view the data in the mysql database, and list it on a table: if($_POST['general'] == 'ADDRESS'){ $result2 = mysql_query("SELECT * FROM student WHERE ADDRESS='$saddress'"); echo "<table border='1'> <tr> <th>IDNO</th> <th>ADDRESS</th> <th>LASTNAME</th> <th>FIRSTNAME</th> <th>VIEW</th> </tr>"; while($row = mysql_fetch_array($result2)) { echo "<tr>"; echo "<td>" . $row['IDNO'] . "</td>"; echo "<td>" . $row['ADDRESS'] . "</td>"; echo "<td>" . $row['LASTNAME'] . "</td>"; echo "<td>" . $row['FIRSTNAME'] . "</td>"; echo "<td><a href='update.php?id=" . $row['IDNO'] . "'>view</a></td>"; echo "</tr>"; } echo "</table>"; } And this one is the update.php which I am working on, I just want to be able to see the data that corresponds to the one the record that I clicked on the first one using the link "view". <?php mysql_select_db("school", $con); $result3 = mysql_query("SELECT * FROM student WHERE IDNO='?'"); ?> <tr> <td width="30" height="35"><font size="3">*I D Number:</td> <td width="30"><input name="idnum" onkeypress="return isNumberKey(event)" type="text" maxlength="5" id='numbers'/ value="<?php echo $row["IDNO"]; ?>"></td> </tr> But I do not know how do I link the two, in such a way that the corresponding data in here: echo "<td><a href='update.php?id=" . $row['IDNO'] . "'>view</a></td>"; would be reflected in here: <td width="30"><input name="idnum" onkeypress="return isNumberKey(event)" type="text" maxlength="5" id='numbers'/ value="<?php echo $row["IDNO"]; ?>"></td> </tr> Please give me an idea on how I can do this, thanks.

  There are lots of suggested fixes for this but none of them work for me. I have tried making the upload class (using the following methods: http://codeigniter.com/forums/viewthread/148605/ and http://codeigniter.com/forums/viewthread/125441/). When i try to upload an mp3 i get the error message "The filetype you are attempting to upload is not allowed". Below is my code for my model and my form (i've got a very skinny controller).

• How can I bind events to strongly typed datasets of different types?

  My application contains several forms which consist of a strongly typed datagridview, a strongly typed bindingsource, and a strongly typed table adapter. I am using some code in each form to update the database whenever the user leaves the current row, shifts focus away from the datagrid or the form, or closes the form. This code is the same in each case, so I want to make a subclass of form, from which all of these forms can inherit. But the strongly typed data objects all inherit from component, which doesn't expose the events I want to bind to or the methods I want to invoke. The only way I can see of gaining access to the events is to use: Type(string Name).GetEvent(string EventName).AddEventHandler(object Target,Delegate Handler) Similarly, I want to call the Update method of the strongly typed table adapter, and am using Type(string Name).GetMethod(String name, Type[] params).Invoke(object target, object[] params). It works ok, but it seems very heavy handed. Is there a better way? Here is my code for the main class: using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Windows.Forms; using System.Data; using System.Data.SqlClient; using System.ComponentModel; namespace MyApplication { public class AutoSaveDataGridForm: Form { private DataRow PreviousRow; public Component Adapter { private get; set; } private Component dataGridView; public Component DataGridView { private get { return dataGridView; } set { dataGridView = value; Type t = dataGridView.GetType(); t.GetEvent("Leave").AddEventHandler(dataGridView, new EventHandler(DataGridView_Leave)); } } private Component bindingSource; public Component BindingSource { private get { return bindingSource; } set { bindingSource = value; Type t = bindingSource.GetType(); t.GetEvent("PositionChanged").AddEventHandler(bindingSource, new EventHandler(BindingSource_PositionChanged)); } } protected void Save() { if (PreviousRow != null && PreviousRow.RowState != DataRowState.Unchanged) { Type t = Adapter.GetType(); t.GetMethod("Update", new Type[] { typeof(DataRow[]) }).Invoke(Adapter, new object[] { new DataRow[] { PreviousRow } }); } } private void BindingSource_PositionChanged(object sender, EventArgs e) { BindingSource bindingSource = sender as BindingSource; DataRowView CurrentRowView = bindingSource.Current as DataRowView; DataRow CurrentRow = CurrentRowView.Row; if (PreviousRow != null && PreviousRow != CurrentRow) { Save(); } PreviousRow = CurrentRow; } private void InitializeComponent() { this.SuspendLayout(); // // AutoSaveDataGridForm // this.FormClosed += new System.Windows.Forms.FormClosedEventHandler(this.AutoSaveDataGridForm_FormClosed); this.Leave += new System.EventHandler(this.AutoSaveDataGridForm_Leave); this.ResumeLayout(false); } private void DataGridView_Leave(object sender, EventArgs e) { Save(); } private void AutoSaveDataGridForm_FormClosed(object sender, FormClosedEventArgs e) { Save(); } private void AutoSaveDataGridForm_Leave(object sender, EventArgs e) { Save(); } } } And here is a (partial) form which implements it: public partial class FileTypesInherited :AutoSaveDataGridForm { public FileTypesInherited() { InitializeComponent(); } private void FileTypesInherited_Load(object sender, EventArgs e) { // TODO: This line of code loads data into the 'sharedFoldersInformationV2DataSet.tblFileTypes' table. You can move, or remove it, as needed. this.tblFileTypesTableAdapter.Fill(this.sharedFoldersInformationV2DataSet.tblFileTypes); this.BindingSource = tblFileTypesBindingSource; this.Adapter = tblFileTypesTableAdapter; this.DataGridView = tblFileTypesDataGridView; } }

• WPF BackgroundWorker Execution

  - by Sanju

  Hi All, I've been programming C# for a while now (I'm a Computer Science major), and have never had to implement threading. I am currently building an application for a client that requires threading for a series of operations. Due to the nature of the client/provider agreement, I cannot release the source I am working with. The code that I have posted is in a general form. Pretty much the basic idea of what I am implementing, excluding the content specific source. The first Snippet demonstrates my basic structure, The Progress class is a custom progress window that is displayed as a dialog to prevent user UI interaction. I am currently using the code to complete database calls based on a collection of objects in another area of the application code. For example, I have a collection of "Objects" of one of my custom classes, that I perform these database calls on or on behalf of. My current set up works just fine when I call the "GeneralizedFunction" one and only one time. What I need to do is call this function once for every object in the collection. I was attempting to use a foreach loop to iterate through the collection, then I tried a for loop. For both loops, the result was the same. The Async operation performs exactly as desired for the first item in the collection. This, however, is the only one it works for. For each subsequent item, the progress box (my custom window) displays and immediately closes. In terms of the database calls, the calls for the first item in the collection are the only ones that successfully complete. All others aren't attempted. I've tried everything that I know and don't know to do, but I just cannot seem to get it to work. How can I get this to work for my entire collection? Any and all help is very greatly appreciated. Progress progress; BackgroundWorker worker; // Cancel the current process private void CancelProcess(object sender, EventArgs e) { worker.CancelAsync(); } // The main process ... "Generalized" private void GeneralizedFunction() { progress = new Progress(); progress.Cancel += CancelProcess; progress.Owner = this; Dispatcher pDispatcher = progress.Dispatcher; worker = new BackgroundWorker(); worker.WorkerSupportsCancellation = true; object[] workArgs = { arg1, arg2, arg3}; worker.DoWork += delegate(object s, DoWorkEventArgs args) { /* All main logic here */ foreach(Class ClassObject in ClassObjectCollection) { //Some more logic here UpdateProgressDelegate update = new UpdateProgressDelegate(updateProgress); pDispatcher.BeginInvoke(update, arg1,arg2,arg3); Thread.Sleep(1000); } }; worker.RunWorkerCompleted += delegate(object s, RunWorkerCompletedEventArgs args) { progress.Close(); }; worker.RunWorkerAsync(workArgs); progress.ShowDialog(); } public delegate void UpdateProgressDelegate(arg1,arg2,arg3); private void updateProgress(arg1,arg2,arg3) { //Update progress }

• How to prevent client from accessing JSP page

  - by Ali Bassam

  In my web application, I use the .load() function in JQuery, to load some JSP pages inside a DIV. $("#myDiv").load("chat.jsp"); In chat.jsp, no Java codes is executed unless this client has Logged in, means, I check the session. String sessionId = session.getAttribute("SessionId"); if(sessionId.equals("100")){ //execute codes }else{ //redirect to log in page } Those java codes that will be executed, they will out.println(); some HTML elements. I don't want the client to write /chat.jsp in the browser to access this page, as it will look bad, and the other stuff in the main page won't be there, and this could do a harm to the web app security. How can I restrict someone from accessing chat.jsp directly, but yet keep it accessible via .load() ? UPDATE: JavaDB is a class that I made, it connects me to the Database. This is chat.jsp <body> <% String userId = session.getAttribute("SessionId").toString(); if (userId != null) { String roomId = request.getParameter("roomId"); String lastMessageId = request.getParameter("lastMessageId"); JavaDB myJavaDB = new JavaDB(); myJavaDB.Connect("Chat", "chat", "chat"); Connection conn = myJavaDB.getMyConnection(); Statement stmt = conn.createStatement(); String lastId = ""; int fi = 0; ResultSet rset = stmt.executeQuery("select message,message_id,first_name,last_name from users u,messages m where u.user_id=m.user_id and m.message_id>" + lastMessageId + " and room_id=" + roomId + " order by m.message_id asc"); while (rset.next()) { fi = 1; lastId = rset.getString(2); %> <div class="message"> <div class="messageSender"> <%=rset.getString(3) + " " + rset.getString(4)%> </div> <div class="messageContents"> <%=rset.getString(1)%> </div> </div> <% } %> <div class="lastId"> <% if (fi == 1) {%> <%=lastId%> <% } else {%> <%=lastMessageId%> <% }%></div> <% if (fi == 1) {%> <div class="messages"> </div> <% } } else { response.sendRedirect("index.jsp"); }%> </body> Guys I don't know what Filter means. UPDATE If I decided to send a parameter that tells me that this request came from Jquery. .load("chat.jsp",{ jquery : "yes" }); And then check it in chat.jsp String yesOrNo = request.getParameter("jquery"); Then they can simply hack this by using this URL. /chat.jsp?jquer=yes or something like that.. UPDATE I tried Maksim's advice, I got this when I tried to access chat.jsp. Is this the desired effect?

  I have the following code for my optin form: <script language="JavaScript"> function checkSub(){ if (document.signup.email.value.indexOf('@', 0) == -1) { alert("Please fill in your valid Email address.\nYour email should be in the following format: [email protected]"); document.signup.email.focus(); return false} else if (!document.signup.terms.checked) { alert("You must read and agree to the terms"); document.signup.terms.focus(); return false} else { switch(document.signup.extra1.value) { case "Platinum": answer = confirm("By clicking OK you confirm that you have\nalready entered the World Cup Giveaway\nas a Platinum upgrade contributor.\n\nIf you have not yet entered the giveaway\nclick Cancel.\n\nYou can enter using the link at the\nbottom of the page.\n\nIf you have already entered the giveaway\nusing a link other than my invitation link\nyou are not eligible for this offer."); if (!answer) { return false} break; case "Gold": answer = confirm("By clicking OK you confirm that you have\nalready entered the World Cup Giveaway\nas a Gold upgrade contributor.\n\nIf you have not yet entered the giveaway\nclick Cancel.\n\nYou can enter using the link at the\nbottom of the page. \n\nIf you have already entered the giveaway\nusing a link other than my invitation link\nyou are not eligible for this offer."); if (!answer) { return false} break; default: alert("You must sign up as a contributor to the \nWorld Cup Giveaway to take advantage of \nthis offer.\n\nPlease click the link at the bottom of this \npage or at the blog post mentioned below \nto sign up.\n\nIf you have already signed up using \nthis link, please select the upgrade level\nyou chose on signup or select \"Free\" if \nyou signed up as a free contributor.\n\nIf you have already entered the giveaway\nusing a link other than my invitation link\nyou are not eligible for this offer.\n\nNote: This page may not function properly\nif viewed in languages other than English."); return false} } } </script> <form action="http://ebizac.com/ar/optin.php" method="post" name="signup" onsubmit="return checkSub()"> <input type=hidden name="action" value="addlead"> <input type=hidden name="member" value="2315"> <input type=hidden name="auto" value="7584"> <input type=hidden name="thankyou" value="http://plr.forinternetnewbies.com/Offer1"> <input type=hidden name="resubsetting" value="Y"> <input type=hidden name="resubredirect" value=""> <input type=hidden name="invalid_redirect" value=""> <div style="padding:0 0 0 10px;"> <table border=0 cellspacing=0 cellpadding=2><tr><td class="label"><font size="2" face="arial, verdana">Name:</font></td><td><input type=text size=20 name="fname"></td></tr> <tr><td class="label" width="150"><font size="2" face="arial, verdana">Email address:</font></span></td><td><input type=text size=20 name="email"></td></tr> <tr><td class="label"><font size="2" face="arial, verdana">Upgrade Level:</font></td><td><select size=1 name="extra1"><option>Haven't Joined Yet</option><option>Platinum</option><option>Gold</option><option>Silver</option><option>Free</option></td></tr> <tr><td></td><td align=center><input type="checkbox" name="terms" value="agree">I agree to the terms as described on the <a href="http://short9.com/blog0522-sp" target="_blank">blog post</a> </td></tr> <tr><td></td><td align=center><input type="submit" value="Contribute Now"></td></tr></table></div></form> Everything does what I expect in Firefox, but in Internet Explorer the switch statement always goes to the default case. I tested with an extra alert(signup.extra1.value) in the default case and it shows an empty string. What could be the problem here?

• Unit testing authorization in a Pylons app fails; cookies aren't been correctly set or recorded

  - by Ian Stevens

  I'm having an issue running unit tests for authorization in a Pylons app. It appears as though certain cookies set in the test case may not be correctly written or parsed. Cookies work fine when hitting the app with a browser. Here is my test case inside a paste-generated TestController: def test_good_login(self): r = self.app.post('/dologin', params={'login': self.user['username'], 'password': self.password}) r = r.follow() # Should only be one redirect to root assert 'http://localhost/' == r.request.url assert 'Dashboard' in r This is supposed to test that a login of an existing account forwards the user to the dashboard page. Instead, what happens is that the user is redirected back to the login. The first POST works, sets the user in the session and returns cookies. Although those cookies are sent in the follow request, they don't seem to be correctly parsed. I start by setting a breakpoint at the beginning of the above method and see what the login response returns: > nosetests --pdb --pdb-failure -s foo.tests.functional.test_account:TestMainController.test_good_login Running setup_config() from foo.websetup > /Users/istevens/dev/foo/foo/tests/functional/test_account.py(33)test_good_login() -> r = self.app.post('/dologin', params={'login': self.user['username'], 'password': self.password}) (Pdb) n > /Users/istevens/dev/foo/foo/tests/functional/test_account.py(34)test_good_login() -> r = r.follow() # Should only be one redirect to root (Pdb) p r.cookies_set {'auth_tkt': '"4c898eb72f7ad38551eb11e1936303374bd871934bd871833d19ad8a79000000!"'} (Pdb) p r.request.environ['REMOTE_USER'] '4bd871833d19ad8a79000000' (Pdb) p r.headers['Location'] 'http://localhost/?__logins=0' A session appears to be created and a cookie sent back. The browser is redirected to the root, not the login, which also indicates a successful login. If I step past the follow(), I get: > /Users/istevens/dev/foo/foo/tests/functional/test_account.py(35)test_good_login() -> assert 'http://localhost/' == r.request.url (Pdb) p r.request.headers {'Host': 'localhost:80', 'Cookie': 'auth_tkt=""\\"4c898eb72f7ad38551eb11e1936303374bd871934bd871833d19ad8a79000000!\\"""; '} (Pdb) p r.request.environ['REMOTE_USER'] *** KeyError: KeyError('REMOTE_USER',) (Pdb) p r.request.environ['HTTP_COOKIE'] 'auth_tkt=""\\"4c898eb72f7ad38551eb11e1936303374bd871934bd871833d19ad8a79000000!\\"""; ' (Pdb) p r.request.cookies {'auth_tkt': ''} (Pdb) p r <302 Found text/html location: http://localhost/login?__logins=1&came_from=http%3A%2F%2Flocalhost%2F body='302 Found...y. '/149> This indicates to me that the cookie was passed in on the request, although with dubious escaping. The environ appears to be without the session created on the prior request. The cookie has been copied to the environ from the headers, but the cookies in the request seems incorrectly set. Lastly, the user is redirected to the login page, indicating that the user isn't logged in. Authorization in the app is done via repoze.who and repoze.who.plugins.ldap with repoze.who_friendlyform performing the challenge. I'm using the stock tests.TestController created by paste: class TestController(TestCase): def __init__(self, *args, **kwargs): if pylons.test.pylonsapp: wsgiapp = pylons.test.pylonsapp else: wsgiapp = loadapp('config:%s' % config['__file__']) self.app = TestApp(wsgiapp) url._push_object(URLGenerator(config['routes.map'], environ)) TestCase.__init__(self, *args, **kwargs) That's a webtest.TestApp, by the way. The encoding of the cookie is done in webtest.TestApp using Cookie: >>> from Cookie import _quote >>> _quote('"84533cf9f661f97239208fb844a09a6d4bd8552d4bd8550c3d19ad8339000000!"') '"\\"84533cf9f661f97239208fb844a09a6d4bd8552d4bd8550c3d19ad8339000000!\\""' I trust that that's correct. My guess is that something on the response side is incorrectly parsing the cookie data into cookies in the server-side request. But what? Any ideas?

• How to schedule dynamic function with cron job?

  - by iBrazilian2

  I want to know how I can schedule a dynamic(auto populated data) function to auto run everyday at saved time? Let's say I have a form that once the button is clicked it sends the data to the function, which the posts the data. I simply want to automate that so that I don't have to press the button. <ul> <?php foreach($Class->retrieveData as $data) { <form method="post" action=""> <li> <input type="hidden" name="name">'.$data['name'].'<br/> <input type="hidden" name="description">'.$data['description'].'<br/> <input type="submit" name="post_data" value="Post"> </li> </form> } ?> </ul> Now, the form will pass the data to the function. if(isset($_POST['post_data'])) // if post_data button is clicked then it runs myFunction() { myFunction(); } myFunction() { $name = $_POST['name']; $description = $_POST['description']; } I tried doing the following but the problem is that Cron Job can only run the whole .php file, and I am retrieving the saved time to run from MySQL. foreach($Class->getTime() as $timeData) { $timeHour = $timeData['timeHour']; $timeMinute = $timeData['timeMinute']; $hourMin = date('H:i'); $timeData = ''.$timeHour.':'.$timeMinute.''; if($hourMin == $timeData) { run myFunction. } } $hourMin is the current hour:minute which is being matched against a saved time to auto run from Mysql. So if $hourMin == $timeData then the function will run. How can I run Cron Job to auto run myFunction() if the $hourMin equals $timeData? So... List 1 = is to be runned at 10am List 2 = is to be runned at 12pm List 3 = is to be runned at 2pm The 10am, 12pm, 2pm is the $timeHour and $timeMinute that is retrieved from MySQL but based on each list id's. EDIT @randomSeed, 1) I can schedule cron jobs. 2) $name and $description will all be arrays, so the following is what I am trying to accomplish. $name = array( 'Jon', 'Steven', 'Carter' ); $description = array( 'Jon is a great person.', 'Steven has an outgoing character.', 'Carter is a horrible person.' ); I want to parse the first arrays from both $name and $description if the scheduled time is correct. In database I have the following postDataTime table +----+---------+----------+------------+--------+ | iD | timeDay | timeHour | timeMinute | postiD | +--------------------------------------+--------+ | 1 | * | 9 | 0 | 21 | |----|---------|----------|------------|--------| | 2 | * | 10 | 30 | 22 | |----|---------|----------|------------|--------| | 3 | * | 11 | 0 | 23 | +----|---------+----------+------------+--------+ iD = auto incremented on upload. timeDay = * is everyday (cron job style) timeHour = Hour of the day to run the script timeMinute = minute of the hour to run script postiD = this is the id of the post that is located in another table (n+1 relationship) If it's difficult to understand.. if(time() == 10:30(time from MySQL postiD = 22)) { // run myFunction with the data that is retrieved for that time ex: $postiD = '22'; $name = 'Steven'; $description = 'Steven has an outgoing character.'; // the above is what will be in the $_POST from the form and will be // sent to the myFunction() } I simply want to schedule everything according to the time that is saved to MySQL as I showed at the very top(postDataTime table). (I'd show what I have tried, but I have searched for countless hours for an example of what I am trying to accomplish but I cannot find anything and what I tried doesn't work.). I thought I could use the exec() function but from what it seems that does not allow me to run functions, otherwise I would do the following.. $time = '10:30'; if($time == time()) { exec(myFunction()); }

• Updating D3 column chart with different values and different data sizes

  - by mbeasley

  Background I am attempting to create a reusable chart object with D3.js. I have setup a chart() function that will produce a column chart. On a click event on any of the columns, the chart will update with a new random data array that will contain a random number of data points (i.e. the original chart could have 8 columns, but upon update, could have 20 columns or 4 columns). Problem Say I have 8 data points (and thus 8 columns) in my original dataset. When I update the chart with random data, the columns appropriately adjust their height to the new values - but new bars aren't added. Additionally, while the width of the columns appropriately adjust to accommodate the width of the container and the new number of data points, if that number of data points is less than the original set, then some of those columns from the original dataset will linger until the number of data points is greater than or equal than the original. My end goal is to have new data dynamically added or old data outside of the range of the new data count dynamically removed. I've created a jsfiddle of the behavior. You may have to click the columns a couple of times to see the behavior I'm describing. Additionally, I've pasted my code below. Thanks in advance! function chart(config) { // set default options var defaultOptions = { selector: '#chartZone', class: 'chart', id: null, data: [1,2,6,4, 2, 6, 7, 2], type: 'column', width: 200, height: 200, callback: null, interpolate: 'monotone' }; // fill in unspecified settings in the config with the defaults var settings = $.extend(defaultOptions, config); function my() { // generate chart with this function var w = settings.width, h = settings.height, barPadding = 3, scale = 10, max = d3.max(settings.data); var svg = d3.select(settings.selector) // create the main svg container .append("svg") .attr("width",w) .attr("height",h); var y = d3.scale.linear().range([h, 0]), yAxis = d3.svg.axis().scale(y).ticks(5).orient("left"), x = d3.scale.linear().range([w, 0]); y.domain([0, max]).nice(); x.domain([0, settings.data.length - 1]).nice(); var rect = svg.selectAll("rect") .data(settings.data) .enter() .append("rect") .attr("x", function(d,i) { return i * (w / settings.data.length); }) .attr("y", function(d) { return h - h * (d / max); }) .attr("width", w / settings.data.length - barPadding) .attr("height", function(d) { return h * (d / max); }) .attr("fill", "rgb(90,90,90)"); svg.append("svg:g") .attr("class", "y axis") .attr("transform", "translate(-4,0)") .call(yAxis); svg.on("click", function() { var newData = [], maxCap = Math.round(Math.random() * 100); for (var i = 0; i < Math.round(Math.random()*100); i++) { var newNumber = Math.random() * maxCap; newData.push(Math.round(newNumber)); } newMax = d3.max(newData); y.domain([0, newMax]).nice(); var t = svg.transition().duration(750); t.select(".y.axis").call(yAxis); rect.data(newData) .transition().duration(750) .attr("height", function(d) { return h * (d / newMax); }) .attr("x", function(d,i) { return i * (w / newData.length); }) .attr("width", w / newData.length - barPadding) .attr("y", function(d) { return h - h * (d / newMax); }); }); } my(); return my; } var myChart = chart();

I need to replace it with blur function but when I try to replace mouseup with blur the program thas not work becose, when I click on the cell I able to enter the input tag and I can change the value but I can't Successful to Leave the tag/field by clicking out side the table, which alow me to update the DataBase you can see that Demo with blur Here. what you advice me to do? $(".edittd").mouseup(function() { return false; }); //************* $(document).mouseup(function() { $('#span' + COLUME + ROW).show(); $('#input'+ COLUME + ROW ).hide(); VAL = $("#input" + COLUME + ROW).val(); $("#span" + COLUME + ROW).html(VAL); if(STATUS != VAL){ //******ajax code //dataString = $.trim(this.value); $.ajax({ type: "POST", dataType: 'html', url: "./public/php/ajax.php", data: 'COLUME='+COLUME+'&ROW='+ROW+'&VAL='+VAL, //{"dataString": dataString} cache: false, success: function(data) { $("#statuS").html(data); } }); //******end ajax $('#statuS').removeClass('statuSnoChange') .addClass('statuSChange'); $('#statuS').html('THERE IS CHANGE'); $('#tables').load('TableEdit2.php'); } else { //alert(DATASTRING+'status not true'); } });//End mouseup function I change it to: $(document).ready(function() { var COLUMES,COLUME,VALUE,VAL,ROWS,ROW,STATUS,DATASTRING; $('td').click(function() { COLUME = $(this).attr('class'); }); //**************** $('tr').click(function() { ROW = $(this).attr('id'); $('#display_Colume_Raw').html(COLUME+ROW); $('#span' + COLUME + ROW).hide(); $('#input'+ COLUME + ROW ).show(); STATUS = $("#input" + COLUME + ROW).val(); }); //******************** $(document).blur(function() { $('#span' + COLUME + ROW).show(); $('#input'+ COLUME + ROW ).hide(); VAL = $("#input" + COLUME + ROW).val(); $("#span" + COLUME + ROW).html(VAL); if(STATUS != VAL){ //******ajax code //dataString = $.trim(this.value); $.ajax({ type: "POST", dataType: 'html', url: "./public/php/ajax.php", data: 'COLUME='+COLUME+'&ROW='+ROW+'&VAL='+VAL, //{"dataString": dataString} cache: false, success: function(data) { $("#statuS").html(data); } }); //******end ajax $('#statuS').removeClass('statuSnoChange') .addClass('statuSChange'); $('#statuS').html('THERE IS CHANGE'); $('#tables').load('TableEdit2.php'); } else { //alert(DATASTRING+'status not true'); } });//End mouseup function $('#save').click (function(){ var input1,input2,input3,input4=""; input1 = $('#input1').attr('value'); input2 = $('#input2').attr('value'); input3 = $('#input3').attr('value'); input4 = $('#input4').attr('value'); $.ajax({ type: "POST", url: "./public/php/ajax.php", data: "input1="+ input1 +"&input2="+ input2 +"&input3="+ input3 +"&input4="+ input4, success: function(data){ $("#statuS").html(data); $('#tbl').hide(function(){$('div.success').fadeIn();}); $('#tables').load('TableEdit2.php'); } }); }); }); Thx

• How to debug KVO

  - by user8472

  In my program I use KVO manually to observe changes to values of object properties. I receive an EXC_BAD_ACCESS signal at the following line of code inside a custom setter: [self willChangeValueForKey:@"mykey"]; The weird thing is that this happens when a factory method calls the custom setter and there should not be any observers around. I do not know how to debug this situation. Update: The way to list all registered observers is observationInfo. It turned out that there was indeed an object listed that points to an invalid address. However, I have no idea at all how it got there. Update 2: Apparently, the same object and method callback can be registered several times for a given object - resulting in identical entries in the observed object's observationInfo. When removing the registration only one of these entries is removed. This behavior is a little counter-intuitive (and it certainly is a bug in my program to add multiple entries at all), but this does not explain how spurious observers can mysteriously show up in freshly allocated objects (unless there is some caching/reuse going on that I am unaware of). Modified question: How can I figure out WHERE and WHEN an object got registered as an observer? Update 3: Specific sample code. ContentObj is a class that has a dictionary as a property named mykey. It overrides: + (BOOL)automaticallyNotifiesObserversForKey:(NSString *)theKey { BOOL automatic = NO; if ([theKey isEqualToString:@"mykey"]) { automatic = NO; } else { automatic=[super automaticallyNotifiesObserversForKey:theKey]; } return automatic; } A couple of properties have getters and setters as follows: - (CGFloat)value { return [[[self mykey] objectForKey:@"value"] floatValue]; } - (void)setValue:(CGFloat)aValue { [self willChangeValueForKey:@"mykey"]; [[self mykey] setObject:[NSNumber numberWithFloat:aValue] forKey:@"value"]; [self didChangeValueForKey:@"mykey"]; } The container class has a property contents of class NSMutableArray which holds instances of class ContentObj. It has a couple of methods that manually handle registrations: + (BOOL)automaticallyNotifiesObserversForKey:(NSString *)theKey { BOOL automatic = NO; if ([theKey isEqualToString:@"contents"]) { automatic = NO; } else { automatic=[super automaticallyNotifiesObserversForKey:theKey]; } return automatic; } - (void)observeContent:(ContentObj *)cObj { [cObj addObserver:self forKeyPath:@"mykey" options:0 context:NULL]; } - (void)removeObserveContent:(ContentObj *)cObj { [cObj removeObserver:self forKeyPath:@"mykey"]; } - (void)observeValueForKeyPath:(NSString *)keyPath ofObject:(id)object change:(NSDictionary *)change context:(void *)context { if (([keyPath isEqualToString:@"mykey"]) && ([object isKindOfClass:[ContentObj class]])) { [self willChangeValueForKey:@"contents"]; [self didChangeValueForKey:@"contents"]; } } There are several methods in the container class that modify contents. They look as follows: - (void)addContent:(ContentObj *)cObj { [self willChangeValueForKey:@"contents"]; [self observeDatum:cObj]; [[self contents] addObject:cObj]; [self didChangeValueForKey:@"contents"]; } And a couple of others that provide similar functionality to the array. They all work by adding/removing themselves as observers. Obviously, anything that results in multiple registrations is a bug and could sit somewhere hidden in these methods. My question targets strategies on how to debug this kind of situation. Alternatively, please feel free to provide an alternative strategy for implementing this kind of notification/observer pattern.

• How to filter using a dropdown in Knockout

  - by user517406

  I have just started using Knockout and I want to filter my data that I am displaying in my UI by selecting an item from a dropdown. I have got so far, but I cannot get the selected value from my dropdown yet, and then after that I need to actually filter the data displayed based upon that value.

• Programatically add UserControl with events

  - by schaermu

  Hi everybody I need to add multiple user controls to a panel for further editing of the contained data. My user control contains some panels, dropdown lists and input elements, which are populated in the user control's Page_Load event. protected void Page_Load(object sender, EventArgs e) { // populate comparer ddl from enum string[] enumNames = Enum.GetNames(typeof (SearchComparision)); var al = new ArrayList(); for (int i = 0; i < enumNames.Length; i++) al.Add(new {Value = i, Name = enumNames[i]}); scOperatorSelection.DataValueField = "Value"; scOperatorSelection.DataTextField = "Name"; ... The data to be displayed is added to the user control as a Field, defined above Page_Load. The signature of the events is the following: public delegate void ControlStateChanged(object sender, SearchCriteriaEventArgs eventArgs); public event ControlStateChanged ItemUpdated; public event ControlStateChanged ItemRemoved; public event ControlStateChanged ItemAdded; The update button on the user control triggers the following method: protected void UpdateCriteria(object sender, EventArgs e) { var searchCritCtl = (SearchCriteria) sender; var scEArgs = new SearchCriteriaEventArgs { TargetCriteria = searchCritCtl.CurrentCriteria.CriteriaId, SearchComparision = ParseCurrentComparer(searchCritCtl.scOperatorSelection.SelectedValue), SearchField = searchCritCtl.scFieldSelection.SelectedValue, SearchValue = searchCritCtl.scFilterValue.Text, ClickTarget = SearchCriteriaClickTarget.Update }; if (ItemUpdated != null) ItemUpdated(this, scEArgs); } The rendering page fetches the data objects from a storage backend and displays it in it's Page_Load event. This is the point where it starts getting tricky: i connect to the custom events! int idIt = 0; foreach (var item in _currentSearch.Items) { SearchCriteria sc = (SearchCriteria)LoadControl("~/content/controls/SearchCriteria.ascx"); sc.ID = "scDispCtl_" + idIt; sc.ControlMode = SearchCriteriaMode.Display; sc.CurrentCriteria = item; sc.ItemUpdated += CriteriaUpdated; sc.ItemRemoved += CriteriaRemoved; pnlDisplayCrit.Controls.Add(sc); idIt++; } When first rendering the page, everything is displayed fine, i get all my data. When i trigger an update event, the user control event is fired correctly, but all fields and controls of the user control are NULL. After a bit of research, i had to come to the conclusion that the event is fired before the controls are initialized... Is there any way to prevent such behavior / to override the page lifecycle somehow? I cannot initialize the user controls in the page's Init-event, because i have to access the Session-Store (not initialized in Page_Init). Any advice is welcome... EDIT: Since we hold all criteria informations in the storage backend (including the count of criteria) and that store uses the userid from the session, we cannot use Page_Init... just for clarification EDIT #2: I managed to get past some of the problems. Since i'm now using simple types, im able to bind all the data declaratively (using a repeater with a simple ItemTemplate). It is bound to the control, they are rendered in correct fashion. On Postback, all the data is rebound to the user control, data is available in the OnDataBinding and OnLoad events, everything looks fine. But as soon it enters the real event (bound to the button control of the user control), all field values are lost somehow... Does anybody know, how the page lifecycle continues to process the request after Databinding/Loading ? I'm going crazy about this issue...
