php slideshow sample

- by serhio

I try to do a simple image slideshow in php (just cycle images, no links, no other effects). after some googling I found the following in net: <HTML> <HEAD> <TITLE>Php Slideshow</TITLE> <script language="javascript"> var speed = 4000; // time picture is displayed var delay = 3; // time it takes to blend to the next picture x = new Array; var y = 0; <?php $tel=0; $tst='.jpg'; $p= "./images"; $d = dir($p); $first = NULL; while (false !== ($entry = $d->read())) { if (stristr ($entry, $tst)) { $entry = $d->path."/".$entry; print ("x[$tel]='$entry';\n"); if ($first == NULL) { $first = $entry; } $tel++; } } $d->close(); ?> function show() { document.all.pic.filters.blendTrans.Apply(); document.all.pic.src = x[y++]; document.all.pic.filters.blendTrans.Play(delay); if (y > x.length - 1) y = 0; } function timeF() { setTimeout(show, speed); } </script> </HEAD> <BODY >  <?php print ("<IMG src='$first' id='pic' onload='timeF()' style='filter:blendTrans()' >"); ?>  </BODY> </HTML> but it displays only the first image from the cycle. Do I something wrong? the resulting HTML page is: <HTML> <HEAD> <TITLE>Php Slideshow</TITLE> <script language="javascript"> var speed = 4000; // time picture is displayed var delay = 3; // time it takes to blend to the next picture x = new Array; var y = 0; x[0]='./images/under_construction.jpg'; x[1]='./images/BuildingBanner.jpg'; x[2]='./images/littleLift.jpg'; x[3]='./images/msfp_smbus1_01.jpg'; x[4]='./images/escalator.jpg'; function show() { document.all.pic.filters.blendTrans.Apply(); document.all.pic.src = x[y++]; document.all.pic.filters.blendTrans.Play(delay); if (y > x.length - 1) y = 0; } function timeF() { setTimeout(show, speed); } </script> </HEAD> <BODY >  <IMG src='./images/under_construction.jpg' id='pic' onload='timeF()' style='filter:blendTrans()' > </BODY> </HTML>

After resolving and calling host via ipv6 with curl, next ipv4 request fails and vice versa

- by Ranty

I need to request the same host with different methods (using IPv4 and IPv6) from the same script. First request is always successful (no matter IPv4 or IPv6), but the second always fails with curl error 45 (Couldn't bind to IP). I'm using the following curl config: function v4_google() { $ch = curl_init(); curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); curl_setopt($ch, CURLOPT_FORBID_REUSE, 1); curl_setopt($ch, CURLOPT_FRESH_CONNECT, 1); curl_setopt($ch, CURLOPT_USERAGENT, 'Mozilla/5.0 (Windows NT 5.1; rv:15.0) Gecko/20100101 Firefox/15.0.1'); curl_setopt($ch, CURLOPT_URL, 'http://www.google.com/search?q=Moon'); curl_setopt($ch, CURLOPT_IPRESOLVE, CURL_IPRESOLVE_V4); curl_setopt($ch, CURLOPT_INTERFACE, 'My IPv4 address'); $c = curl_exec($ch); $result = !curl_errno($ch) ? 'Success' : '<b>' . curl_error($ch) . '; #' . curl_errno($ch) . '</b>'; echo '<p>v4_google:<br>Response length: ' . mb_strlen($c) . '<br>Result: ' . $result . '</p>'; curl_close($ch); } function v6_google() { $ch = curl_init(); curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); curl_setopt($ch, CURLOPT_FORBID_REUSE, 1); curl_setopt($ch, CURLOPT_FRESH_CONNECT, 1); curl_setopt($ch, CURLOPT_USERAGENT, 'Mozilla/5.0 (Windows NT 5.1; rv:15.0) Gecko/20100101 Firefox/15.0.1'); curl_setopt($ch, CURLOPT_URL, 'http://www.google.com/search?q=Moon'); curl_setopt($ch, CURLOPT_IPRESOLVE, CURL_IPRESOLVE_V6); curl_setopt($ch, CURLOPT_INTERFACE, 'My IPv6 address'); $c = curl_exec($ch); $result = !curl_errno($ch) ? 'Success' : '<b>' . curl_error($ch) . '; #' . curl_errno($ch) . '</b>'; echo '<p>v6_google:<br>Response length: ' . mb_strlen($c) . '<br>Result: ' . $result . '</p>'; curl_close($ch); } v6_google(); v4_google(); So long story short, if I query v6_google(); first, then all consecutive calls of v4_google(); are failing with the curl error 45 (Couldn't bind to IP). And vice versa. As you can see, I separated code into different functions and added CURLOPT_FORBID_REUSE and CURLOPT_FRESH_CONNECT plus curl_close($ch), but it didn't help at all. It looks like curl is caching the resolving method of every host you request, and even if you specify another resolving method the next time you call that host, the cached one is used instead. I would appreciate any help with this issue.

Looking for a better design: A readonly in-memory cache mechanism

- by Dylan Lin

Hi all, I have a Category entity (class), which has zero or one parent Category and many child Categories -- it's a tree structure. The Category data is stored in a RDBMS, so for better performance, I want to load all categories and cache them in memory while launching the applicaiton. Our system can have plugins, and we allow the plugin authors to access the Category Tree, but they should not modify the cached items and the tree(I think a non-readonly design might cause some subtle bugs in this senario), only the system knows when and how to refresh the tree. Here are some demo codes: public interface ITreeNode<T> where T : ITreeNode<T> { // No setter T Parent { get; } IEnumerable<T> ChildNodes { get; } } // This class is generated by O/R Mapping tool (e.g. Entity Framework) public class Category : EntityObject { public string Name { get; set; } } // Because Category is not stateless, so I create a cleaner view class for Category. // And this class is the Node Type of the Category Tree public class CategoryView : ITreeNode<CategoryView> { public string Name { get; private set; } #region ITreeNode Memebers public CategoryView Parent { get; private set; } private List<CategoryView> _childNodes; public IEnumerable<CategoryView> ChildNodes { return _childNodes; } #endregion public static CategoryView CreateFrom(Category category) { // here I can set the CategoryView.Name property } } So far so good. However, I want to make ITreeNode interface reuseable, and for some other types, the tree should not be readonly. We are not able to do this with the above readonly ITreeNode, so I want the ITreeNode to be like this: public interface ITreeNode<T> { // has setter T Parent { get; set; } // use ICollection<T> instead of IEnumerable<T> ICollection<T> ChildNodes { get; } } But if we make the ITreeNode writable, then we cannot make the Category Tree readonly, it's not good. So I think if we can do like this: public interface ITreeNode<T> { T Parent { get; } IEnumerable<T> ChildNodes { get; } } public interface IWritableTreeNode<T> : ITreeNode<T> { new T Parent { get; set; } new ICollection<T> ChildNodes { get; } } Is this good or bad? Are there some better designs? Thanks a lot! :)

nextSibling issues...

- by SoLoGHoST

Ok, this has been killing me all night, I mean I've been working on this code for atleast 8 hours now. What is the problem with this, argggg. I am trying to update all <span id="column_[some number]"> to increment it by one after the next id="row_" tr element, but for some god knows what reason, it gives me issues. It's updating the same <span> tag 2x, and this changes it from the desired value to 1 more than it should be... argggg. Here's my code someone please help me here... // Reorder all columns, if any, in the other rows after this 1. if (aRowId != 0 && lId.indexOf("tr_" + aRowId) == 0 && rowComplete != aRowId) { var tempTr = lTable.childNodes[i].childNodes[p]; while(tempTr.nodeType == 1 && tempTr.nextSibling != null) { var tempId = tempTr.getAttribute("id"); if (!tempId) continue; if (tempId.indexOf("row_") == 0) { // All done this row, set it to completed! rowComplete = aRowId; break; } if (tempTr.hasChildNodes) { var doneChilds = false; // grab the id where tdcolumn_{aRowId}.indexOf = 0. for (fcTd = 0; fcTd<tempTr.childNodes.length; fcTd++) { if (tempTr.childNodes[fcTd].nodeName == '#text') continue; var tempfcId = tempTr.childNodes[fcTd].getAttribute("id"); if (!tempfcId) continue; if (tempfcId.indexOf("tdcolumn_" + aRowId) != 0) continue; // looping through the children in the <td> element here. if (tempTr.childNodes[fcTd].hasChildNodes) { for (x = tempTr.childNodes[fcTd].childNodes.length-1; x>0; x--) { if (tempTr.childNodes[fcTd].childNodes[x].nodeName == '#text') continue; var tempSpanId = tempTr.childNodes[fcTd].childNodes[x].getAttribute("id"); if (!tempSpanId) continue; if (tempSpanId.indexOf("column_") != 0) continue; // alert(tempSpanId); alert(tempTr.childNodes[fcTd].childNodes[x].nodeName); var tSpanId = new Array(); tSpanId = tempSpanId.split("_"); if (currColumnId == 0) { currColumnId = parseInt(tSpanId[1]); var incCol = currColumnId; } incCol++; // alert("currColumnId = " + currColumnId + "\n\ntSpanId[1] = " + tSpanId[1] + "\n\nincCol = " + incCol); // Set the new Id's and Text, after which we can exit the for loop. tempTr.childNodes[fcTd].childNodes[x].setAttribute("id", "column_" + incCol); tempTr.childNodes[fcTd].childNodes[x].setAttribute("class", "dp_edit_column"); tempTr.childNodes[fcTd].childNodes[x].innerHTML = oColumnText + " " + incCol; // tempTr.childNodes[fcTd].setAttribute("id", "tdcolumn_" + aRowId + "_" + (parseInt(tSpanId[1])+1) + "_" + tSpanId[3]); doneChilds = true; break; } } else continue; if (doneChilds = true) continue; } } else continue; tempTr = tempTr.nextSibling; } } Please help me, thanks.

Passing a variable from Excel 2007 Custom Task Pane to Hosted PowerShell

- by Uros Calakovic

I am testing PowerShell hosting using C#. Here is a console application that works: using System; using System.Collections; using System.Collections.Generic; using System.Collections.ObjectModel; using System.Management.Automation; using System.Management.Automation.Runspaces; using Microsoft.Office.Interop.Excel; namespace ConsoleApplication3 { class Program { static void Main() { Application app = new Application(); app.Visible = true; app.Workbooks.Add(XlWBATemplate.xlWBATWorksheet); Runspace runspace = RunspaceFactory.CreateRunspace(); runspace.Open(); runspace.SessionStateProxy.SetVariable("Application", app); Pipeline pipeline = runspace.CreatePipeline("$Application"); Collection<PSObject> results = null; try { results = pipeline.Invoke(); foreach (PSObject pob in results) { Console.WriteLine(pob); } } catch (RuntimeException re) { Console.WriteLine(re.GetType().Name); Console.WriteLine(re.Message); } } } } I first create an Excel.Application instance and pass it to the hosted PowerShell instance as a varible named $Application. This works and I can use this variable as if Excel.Application was created from within PowerShell. I next created an Excel addin using VS 2008 and added a user control with two text boxes and a button to the addin (the user control appears as a custom task pane when Excel starts). The idea was this: when I click the button a hosted PowerShell instance is created and I can pass to it the current Excel.Application instance as a variable, just like in the first sample, so I can use this variable to automate Excel from PowerShell (one text box would be used for input and the other one for output. Here is the code: using System; using System.Windows.Forms; using System.Management.Automation; using System.Management.Automation.Runspaces; using System.Collections.ObjectModel; using Microsoft.Office.Interop.Excel; namespace POSHAddin { public partial class POSHControl : UserControl { public POSHControl() { InitializeComponent(); } private void btnRun_Click(object sender, EventArgs e) { txtOutput.Clear(); Microsoft.Office.Interop.Excel.Application app = Globals.ThisAddIn.Application; Runspace runspace = RunspaceFactory.CreateRunspace(); runspace.Open(); runspace.SessionStateProxy.SetVariable("Application", app); Pipeline pipeline = runspace.CreatePipeline( "$Application | Get-Member | Out-String"); app.ActiveCell.Value2 = "Test"; Collection<PSObject> results = null; try { results = pipeline.Invoke(); foreach (PSObject pob in results) { txtOutput.Text += pob.ToString() + "-"; } } catch (RuntimeException re) { txtOutput.Text += re.GetType().Name; txtOutput.Text += re.Message; } } } } The code is similar to the first sample, except that the current Excel.Application instance is available to the addin via Globals.ThisAddIn.Application (VSTO generated) and I can see that it is really a Microsoft.Office.Interop.Excel.Application instance because I can use things like app.ActiveCell.Value2 = "Test" (this actually puts the text into the active cell). But when I pass the Excel.Application instance to the PowerShell instance what gets there is an instance of System.__ComObject and I can't figure out how to cast it to Excel.Application. When I examine the variable from PowerShell using $Application | Get-Member this is the output I get in the second text box: TypeName: System.__ComObject Name MemberType Definition ---- ---------- ---------- CreateObjRef Method System.Runtime.Remoting.ObjRef CreateObj... Equals Method System.Boolean Equals(Object obj) GetHashCode Method System.Int32 GetHashCode() GetLifetimeService Method System.Object GetLifetimeService() GetType Method System.Type GetType() InitializeLifetimeService Method System.Object InitializeLifetimeService() ToString Method System.String ToString() My question is how can I pass an instance of Microsoft.Office.Interop.Excel.Application from a VSTO generated Excel 2007 addin to a hosted PowerShell instance, so I can manipulate it from PowerShell? (I have previously posted the question in the Microsoft C# forum without an answer)

Android: HttpURLConnection not working properly

- by giorgiline

I'm trying to get the cookies from a website after sending user credentials through a POST Request an it seems that it doesn't work in android this way. ¿Am I doing something bad?. Please help. I've searched here in different posts but there's no useful answer. It's curious that this run in a desktop Java implementation it works perfect but it crashes in Android platform. And it is exactly the same code, specifically when calling HttpURLConnection.getHeaderFields(), it also happens with other member methods. It's a simple code and I don't know why the hell isn't working. DESKTOP CODE: This goes just in the main() HttpURLConnection connection = null; OutputStream out = null; try { URL url = new URL("http://www.XXXXXXXX.php"); String charset = "UTF-8"; String postback = "1"; String user = "XXXXXXXXX"; String password = "XXXXXXXX"; String rememberme = "on"; String query = String.format("postback=%s&user=%s&password=%s&rememberme=%s" , URLEncoder.encode(postback, charset) , URLEncoder.encode(user,charset) , URLEncoder.encode(password, charset) , URLEncoder.encode(rememberme, charset)); connection = (HttpURLConnection)url.openConnection(); connection.setRequestMethod("POST"); connection.setRequestProperty("Accept-Charset", charset); connection.setDoOutput(true); connection.setFixedLengthStreamingMode(query.length()); out = connection.getOutputStream (); out.write(query.getBytes(charset)); if (connection.getHeaderFields() == null){ System.out.println("Header null"); }else{ for (String cookie: connection.getHeaderFields().get("Set-Cookie")){ System.out.println(cookie.split(";", 2)[0]); } } } catch (IOException e){ e.printStackTrace(); } finally { try { out.close();} catch (IOException e) { e.printStackTrace();} connection.disconnect(); } So the output is: login_key=20ad8177db4eca3f057c14a64bafc2c9 FASID=cabf20cc471fcacacdc7dc7e83768880 track=30c8183e4ebbe8b3a57b583166326c77 client-data=%7B%22ism%22%3Afalse%2C%22showm%22%3Afalse%2C%22ts%22%3A1349189669%7D ANDROID CODE: This goes inside doInBackground AsyncTask body HttpURLConnection connection = null; OutputStream out = null; try { URL url = new URL("http://www.XXXXXXXXXXXXXX.php"); String charset = "UTF-8"; String postback = "1"; String user = "XXXXXXXXX"; String password = "XXXXXXXX"; String rememberme = "on"; String query = String.format("postback=%s&user=%s&password=%s&rememberme=%s" , URLEncoder.encode(postback, charset) , URLEncoder.encode(user,charset) , URLEncoder.encode(password, charset) , URLEncoder.encode(rememberme, charset)); connection = (HttpURLConnection)url.openConnection(); connection.setRequestMethod("POST"); connection.setRequestProperty("Accept-Charset", charset); connection.setDoOutput(true); connection.setFixedLengthStreamingMode(query.length()); out = connection.getOutputStream (); out.write(query.getBytes(charset)); if (connection.getHeaderFields() == null){ Log.v(TAG, "Header null"); }else{ for (String cookie: connection.getHeaderFields().get("Set-Cookie")){ Log.v(TAG, cookie.split(";", 2)[0]); } } } catch (IOException e){ e.printStackTrace(); } finally { try { out.close();} catch (IOException e) { e.printStackTrace();} connection.disconnect(); } And here there is no output, it seems that connection.getHeaderFields() doesn't return result. It takes al least 30 seconds to show the Log: 10-02 16:56:25.918: V/class com.giorgi.myproject.activities.HomeActivity(2596): Header null

SimpleXMLElement (PHP) throwing error on XML root attributes

- by Greg

I am working on a project that will take XML data submitted through a textarea input in a form then extract the data and throw it into a database. I am getting errors about the attribute in the root field of my XML (it is the same schema each time, but with different values). If i remove these attributes it works fine, but I don't want to have to remove these attributes each I time I go to send the data to the script. here is a sample of my data and code I am using (the part that is giving me errors): <raid generatedFrom="HeadCount" version="1.7.4"> --snip-- </raid> If I post the data as such, i get errors such as: Warning: SimpleXMLElement::__construct() [function.SimpleXMLElement---construct]: Entity: line 1: parser error : AttValue: " or ' expected in /home/content/g/V/i/gViscardi/html/guilds/sanctum/headcount.php on line 13 Warning: SimpleXMLElement::__construct() [function.SimpleXMLElement---construct]: <raid generatedFrom=\"HeadCount\" version=\"1.7.4\"> in /home/content/g/V/i/gViscardi/html/guilds/sanctum/headcount.php on line 13 Warning: SimpleXMLElement::__construct() [function.SimpleXMLElement---construct]: ^ in /home/content/g/V/i/gViscardi/html/guilds/sanctum/headcount.php on line 13 Warning: SimpleXMLElement::__construct() [function.SimpleXMLElement---construct]: Entity: line 1: parser error : attributes construct error in /home/content/g/V/i/gViscardi/html/guilds/sanctum/headcount.php on line 13 Warning: SimpleXMLElement::__construct() [function.SimpleXMLElement---construct]: <raid generatedFrom=\"HeadCount\" version=\"1.7.4\"> in /home/content/g/V/i/gViscardi/html/guilds/sanctum/headcount.php on line 13 Warning: SimpleXMLElement::__construct() [function.SimpleXMLElement---construct]: ^ in /home/content/g/V/i/gViscardi/html/guilds/sanctum/headcount.php on line 13 Warning: SimpleXMLElement::__construct() [function.SimpleXMLElement---construct]: Entity: line 1: parser error : Couldn't find end of Start Tag raid line 1 in /home/content/g/V/i/gViscardi/html/guilds/sanctum/headcount.php on line 13 Warning: SimpleXMLElement::__construct() [function.SimpleXMLElement---construct]: <raid generatedFrom=\"HeadCount\" version=\"1.7.4\"> in /home/content/g/V/i/gViscardi/html/guilds/sanctum/headcount.php on line 13 Warning: SimpleXMLElement::__construct() [function.SimpleXMLElement---construct]: ^ in /home/content/g/V/i/gViscardi/html/guilds/sanctum/headcount.php on line 13 Warning: SimpleXMLElement::__construct() [function.SimpleXMLElement---construct]: Entity: line 1: parser error : Extra content at the end of the document in /home/content/g/V/i/gViscardi/html/guilds/sanctum/headcount.php on line 13 Warning: SimpleXMLElement::__construct() [function.SimpleXMLElement---construct]: <raid generatedFrom=\"HeadCount\" version=\"1.7.4\"> in /home/content/g/V/i/gViscardi/html/guilds/sanctum/headcount.php on line 13 Warning: SimpleXMLElement::__construct() [function.SimpleXMLElement---construct]: ^ in /home/content/g/V/i/gViscardi/html/guilds/sanctum/headcount.php on line 13 Fatal error: Uncaught exception 'Exception' with message 'String could not be parsed as XML' in /home/content/g/V/i/gViscardi/html/guilds/sanctum/headcount.php:13 Stack trace: #0 /home/content/g/V/i/gViscardi/html/guilds/sanctum/headcount.php(13): SimpleXMLElement->__construct('<raid generated...') #1 {main} thrown in /home/content/g/V/i/gViscardi/html/guilds/sanctum/headcount.php on line 13 If I remove the attributes from the root node then it works fine with no errors.

Send smtp mail in php with HTML page attach as a text

- by Nirmal

Hello All.... I have a requirement of sending mail using smtp server in php. Now I am able to send the mail using smtp for a plain text. but I have a requirement where I need to attach an HTML page, which includes set of images. Now for that I am trying the following code : <?php require_once "Mail.php"; $to = '[email protected]'; $from = '[email protected]'; $subject = $_POST['subject']; $body = $_POST['message']; $fileatt = $_FILES['fileatt']['tmp_name']; $fileatt_type = $_FILES['fileatt']['type']; $fileatt_name = $_FILES['fileatt']['name']; $headers = array ('From' => $from, 'To' => $to, 'Subject' => $subject); if (is_uploaded_file($fileatt)) { echo("<p>Inside 1</p>"); $file = fopen($fileatt,'rb'); $data = fread($file,filesize($fileatt)); fclose($file); // Generate a boundary string $semi_rand = md5(time()); $mime_boundary = "==Multipart_Boundary_x{$semi_rand}x"; array_push(&$headers, 'MIME-Version: 1.0'); array_push(&$headers, 'Content-Type: multipart/mixed;'); array_push(&$headers, " boundary=\"{$mime_boundary}\""); echo("<p>Inside 2</p>"); $body = "This is a multi-part message in MIME format.\n\n" . "--{$mime_boundary}\n" . "Content-Type: text/plain; charset=\"iso-8859-1\"\n" . "Content-Transfer-Encoding: 7bit\n\n" . $body . "\n\n"; echo("<p>Inside 3</p>"); $data = chunk_split(base64_encode($data)); echo("<p>Inside 4</p>"); $body .= "--{$mime_boundary}\n" . "Content-Type: {$fileatt_type};\n" . " name=\"{$fileatt_name}\"\n" . "Content-Transfer-Encoding: base64\n\n" . $data . "\n\n" . "--{$mime_boundary}--\n"; echo("<p>Inside 5</p>"); } $host = "[email protected]"; $username = "[email protected]"; $password = "user"; $smtp = Mail::factory('smtp', array ('host' => $host, 'auth' => true, 'username' => $username, 'password' => $password)); $mail = $smtp->send($to, $headers, $body); if (PEAR::isError($mail)) { echo("<p>" . $mail->getMessage() . "</p>"); } else { echo("<p>Message successfully sent!</p>"); } ?> Now this code works fine for me, and it's sending the mail to the target email address. But when I open this email in the inbox, it's showing me the following text in the mailbox: This is a multi-part message in MIME format. --==Multipart_Boundary_x368d72fe1ff44518e90537abdb4bf029x Content-Type: text/plain; charset="iso-8859-1" Content-Transfer-Encoding: 7bit test 1011 --==Multipart_Boundary_x368d72fe1ff44518e90537abdb4bf029x Content-Type: text/html; name="mailing.html" Content-Transfer-Encoding: base64 PCFET0NUWVBFIGh0bWwgUFVCTElDICItLy9XM0MvL0RURCBYSFRNTCAxLjAgVHJhbnNpdGlvbmFs Ly9FTiIgImh0dHA6Ly93d3cudzMub3JnL1RSL3hodG1sMS9EVEQveGh0bWwxLXRyYW5zaXRpb25h ................ So, it's clearly showing me the encoded data. So, what should modify to send the proper html page that should be visible in targeted email's inbox? Thanks in advance...

(PHP) User is being forced to RE-LOGIN after trying to do something on an admin page

- by hatorade

I have created an admin panel for a client in PHP, which requires a login. Here is the code at the top of the admin page requiring the user to be logged in: admin.php <?php session_start(); require("_lib/session_functions.php"); require("_lib/db.php"); db_connect(); //if the user has not logged in if(!isLoggedIn()) { header('Location: login_form.php'); die(); } ?> Obviously, the if statement is what catches them and forces them to log in. Here is the code on the resulting login page: login_form.php <form name="login" action="login.php" method="post"> Username: <input type="text" name="username" /> Password: <input type="password" name="password" /> <input type="submit" value="Login" /> </form> Which posts info to this controller page: login.php <?php session_start(); //must call session_start before using any $_SESSION variables include '_lib/session_functions.php'; $username = $_POST['username']; $password = $_POST['password']; include '_lib/db.php'; db_connect(); // Connect to the DB $username = mysql_real_escape_string($username); $query = "SELECT password, salt FROM users WHERE username = '$username';"; $result = mysql_query($query); if(mysql_num_rows($result) < 1) //no such user exists { header('Location: login_form.php?login=fail'); die(); } $userData = mysql_fetch_array($result, MYSQL_ASSOC); db_disconnect(); $hash = hash('sha256', $password . $userData['salt']); if($hash != $userData['password']) //incorrect password { header('Location: login_form.php?login=fail'); die(); } else { validateUser(); //sets the session data for this user } header('Location: admin.php'); ?> and the session functions page that provides login functions contains this: session_functions.php <?php function validateUser() { session_regenerate_id (); //this is a security measure $_SESSION['valid'] = 1; $_SESSION['userid'] = $username; } function isLoggedIn() { if($_SESSION['valid']) return true; return false; } function logout() { $_SESSION = array(); //destroy all of the session variables if (ini_get("session.use_cookies")) { $params = session_get_cookie_params(); setcookie(session_name(), '', time() - 42000, $params["path"], $params["domain"], $params["secure"], $params["httponly"] ); } session_destroy(); } ?> I grabbed the sessions_functions.php code of an online tutorial, so it could be suspicious. Any ideas why the user logs in to the admin panel, tries to do something, is forced to re-login, and THEN is allowed to do stuff like normal in the admin panel?

Problems with maven output directory

- by Gandalf StormCrow

I'm using almost same POM for both my projects, they are on the same workspace but they are not related at all, they are related however because in both I use spring and jboss.

I changed springversion and jboss home properties variable but everything remains the same, what can I do ? The project builds and all, everything is working perfectly just I don't want to copy everytime in my jboss dir and previously remove the old war, it takes about 20sec on each source code change its a lot

Google App Engine + Form Validation

- by Iwona

Hi, I would like to do google app engine form validation but I dont know how to do it? I tried like this: from google.appengine.ext.db import djangoforms from django import newforms as forms class SurveyForm(forms.Form): occupations_choices = ( ('1', ""), ('2', "Undergraduate student"), ('3', "Postgraduate student (MSc)"), ('4', "Postgraduate student (PhD)"), ('5', "Lab assistant"), ('6', "Technician"), ('7', "Lecturer"), ('8', "Other" ) ) howreach_choices = ( ('1', ""), ('2', "Typed the URL directly"), ('3', "Site is bookmarked"), ('4', "A search engine"), ('5', "A link from another site"), ('6', "From a book"), ('7', "Other") ) boxes_choices = ( ("des", "Website Design"), ("svr", "Web Server Administration"), ("com", "Electronic Commerce"), ("mkt", "Web Marketing/Advertising"), ("edu", "Web-Related Education") ) name = forms.CharField(label='Name', max_length=100, required=True) email = forms.EmailField(label='Your Email Address:') occupations = forms.ChoiceField(choices=occupations_choices, label='What is your occupation?') howreach = forms.ChoiceField(choices=howreach_choices, label='How did you reach this site?') # radio buttons 1-5 rating = forms.ChoiceField(choices=range(1,6), label='What is your occupation?', widget=forms.RadioSelect) boxes = forms.ChoiceField(choices=boxes_choices, label='Are you involved in any of the following?

Error using Session in IIS7

- by flashnik

After deployment of my website to IIS I'm getting a following error message when trying to access session: Session state can only be used when enableSessionState is set to true, either in a configuration file or in the Page directive. Please also make sure that System.Web.SessionStateModule or a custom session state module is included in the \\ section in the application configuration. I access it in Page_Load or PreRender events (I tried both versions). With VS Dev Server it works without a problem. I tried both InProc an SessionState storage, 1 and multiple woker processes. I added a enableSessionState = "true" to my webpage explicitly.

I am trying to use an IV with AES so that the encrypted text is unpredictable. However, the encrypted hex string is always the same.

Action bar with Search View. Reverse compatibility issues

- by suresh

I am building a sample app to demonstrate SearchView with filter and other Action Bar items. I am able to successfully run this app on 4.2(Nexus 7). But it is not running on 2.3. I googled about the issue. Came to know that i should use SherLock Action bar. I just went to http://actionbarsherlock.com/download.html, downloaded the zip file and added the library as informed in the video: http://www.youtube.com/watch?v=4GJ6yY1lNNY&feature=player_embedde by WiseManDesigns. But still I am unable to figure out the issue. Here is my code: SearchViewActionBar.java public class SearchViewActionBar extends Activity implements SearchView.OnQueryTextListener { private SearchView mSearchView; private TextView mStatusView; int mSortMode = -1; private ListView mListView; private ArrayAdapter<String> mAdapter; protected CharSequence[] _options = { "Wild Life", "River", "Hill Station", "Temple", "Bird Sanctuary", "Hill", "Amusement Park"}; protected boolean[] _selections = new boolean[ _options.length ]; private final String[] mStrings = Cheeses.sCheeseStrings; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); getWindow().requestFeature(Window.FEATURE_ACTION_BAR); setContentView(R.layout.activity_main); // mStatusView = (TextView) findViewById(R.id.status_text); // mSearchView = (SearchView) findViewById(R.id.search_view); mListView = (ListView) findViewById(R.id.list_view); mListView.setAdapter(mAdapter = new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, mStrings)); mListView.setTextFilterEnabled(true); //setupSearchView(); } private void setupSearchView() { mSearchView.setIconifiedByDefault(true); mSearchView.setOnQueryTextListener(this); mSearchView.setSubmitButtonEnabled(false); //mSearchView.setQueryHint(getString(R.string.cheese_hunt_hint)); } @Override public boolean onCreateOptionsMenu(Menu menu) { super.onCreateOptionsMenu(menu); MenuInflater inflater = getMenuInflater(); inflater.inflate(R.menu.searchview_in_menu, menu); MenuItem searchItem = menu.findItem(R.id.action_search); mSearchView = (SearchView) searchItem.getActionView(); //setupSearchView(searchItem); setupSearchView(); return true; } @Override public boolean onPrepareOptionsMenu(Menu menu) { if (mSortMode != -1) { Drawable icon = menu.findItem(mSortMode).getIcon(); menu.findItem(R.id.action_sort).setIcon(icon); } return super.onPrepareOptionsMenu(menu); } @Override public boolean onOptionsItemSelected(MenuItem item) { String c="Category"; String s=(String) item.getTitle(); if(s.equals(c)) { System.out.println("same"); showDialog( 0 ); } //System.out.println(s); Toast.makeText(this, "Selected Item: " + item.getTitle(), Toast.LENGTH_SHORT).show(); return true; } protected Dialog onCreateDialog( int id ) { return new AlertDialog.Builder( this ) .setTitle( "Category" ) .setMultiChoiceItems( _options, _selections, new DialogSelectionClickHandler() ) .setPositiveButton( "SAVE", new DialogButtonClickHandler() ) .create(); } public class DialogSelectionClickHandler implements DialogInterface.OnMultiChoiceClickListener { public void onClick( DialogInterface dialog, int clicked, boolean selected ) { Log.i( "ME", _options[ clicked ] + " selected: " + selected ); } } public class DialogButtonClickHandler implements DialogInterface.OnClickListener { public void onClick( DialogInterface dialog, int clicked ) { switch( clicked ) { case DialogInterface.BUTTON_POSITIVE: printSelectedPlanets(); break; } } } protected void printSelectedPlanets() { for( int i = 0; i < _options.length; i++ ){ Log.i( "ME", _options[ i ] + " selected: " + _selections[i] ); } } public void onSort(MenuItem item) { mSortMode = item.getItemId(); invalidateOptionsMenu(); } public boolean onQueryTextChange(String newText) { if (TextUtils.isEmpty(newText)) { mListView.clearTextFilter(); } else { mListView.setFilterText(newText.toString()); } return true; } public boolean onQueryTextSubmit(String query) { mStatusView.setText("Query = " + query + " : submitted"); return false; } public boolean onClose() { mStatusView.setText("Closed!"); return false; } protected boolean isAlwaysExpanded() { return false; } }

Select Multiple Images Using GalleryView

- by hwrdprkns

Hi guys, I was just wondering if Android had built in code so that I could select multiple images in a gallery-view and then have those images exported as filenames in a string array(ex /sdcard/~f1.jpg, /sdcard/~f2.jpg,...). I have the gallery code here, but I'm not sure what modifications need to be made. Any help is appreciated. Thanks! // take_picture = (Button)findViewById(R.id.take_picture); // Here we set up a string array of the thumbnail ID column we want to // get back String[] proj = { MediaStore.Images.Thumbnails._ID }; if(proj.length == 0) { nopic.setVisibility(View.VISIBLE); } // Now we create the cursor pointing to the external thumbnail store cursor = managedQuery( MediaStore.Images.Thumbnails.EXTERNAL_CONTENT_URI, proj, // Which // columns // to // return null, // WHERE clause; which rows to return (all rows) null, // WHERE clause selection arguments (none) null); // Order-by clause (ascending by name) /* take_picture.setOnClickListener(new View.OnClickListener() { public void onClick(View v) { Intent i = new Intent(GalleryActivity.this, CameraActivity.class); startActivity(i); } }); */ // We now get the column index of the thumbnail id column_index = cursor .getColumnIndexOrThrow(MediaStore.Images.Thumbnails._ID); // Reference the Gallery view g = (Gallery) findViewById(R.id.gallery); if(proj.length == 0) { nopic.setVisibility(View.VISIBLE); g.setVisibility(View.GONE); } // Set the adapter to our custom adapter (below) g.setAdapter(new ImageAdapter(this)); // Set a item click listener, and just Toast the clicked position g.setOnItemClickListener(new OnItemClickListener() { public void onItemClick(AdapterView parent, View v, int position, long id) { // Now we want to actually get the data location of the file String[] proj = { MediaStore.Images.Media.DATA }; // We request our cursor again cursor = managedQuery( MediaStore.Images.Media.EXTERNAL_CONTENT_URI, proj, // Which // columns // to // return null, // WHERE clause; which rows to return (all rows) null, // WHERE clause selection arguments (none) null); // Order-by clause (ascending by name) // We want to get the column index for the data uri column_index = cursor .getColumnIndexOrThrow(MediaStore.Images.Media.DATA); // Lets move to the selected item in the cursor cursor.moveToPosition((int) g.getSelectedItemId()); // And here we get the filename String filename = cursor.getString(column_index); Log.v("GalleryActivity", filename); Toast.makeText(GalleryActivity.this, filename, Toast.LENGTH_SHORT).show(); setPrefs(filename); Intent i = new Intent(GalleryActivity.this, OtherClass.class); startActivity(i); } }); } And the ImageAdapter code here: public class ImageAdapter extends BaseAdapter { int mGalleryItemBackground; public ImageAdapter(Context c) { mContext = c; // See res/values/attrs.xml for the that defines // Gallery1. TypedArray a = obtainStyledAttributes(R.styleable.Gallery); mGalleryItemBackground = a.getResourceId( R.styleable.Gallery_android_galleryItemBackground, 0); a.recycle(); } public int getCount() { return cursor.getCount(); } public Object getItem(int position) { return position; } public long getItemId(int position) { return position; } public View getView(int position, View convertView, ViewGroup parent) { ImageView i = new ImageView(mContext); if (convertView == null) { cursor.moveToPosition(position); int id = cursor.getInt(column_index); i.setImageURI(Uri.withAppendedPath( MediaStore.Images.Thumbnails.EXTERNAL_CONTENT_URI, "" + id)); i.setScaleType(ImageView.ScaleType.FIT_XY); i.setLayoutParams(new Gallery.LayoutParams(200, 200)); // The preferred Gallery item background i.setBackgroundResource(mGalleryItemBackground); } return i; } } Again any help is appreciateds! Just to let you guys know, the gallery works fine (for one image) as in it exports the filename correctly. Just need to know if there is an easy way to select multiples and export them. Thanks again!

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; } }

Calculate new position of player

- by user1439111

Edit: I will summerize my question since it is very long (Thanks Len for pointing it out) What I'm trying to find out is to get a new position of a player after an X amount of time. The following variables are known: - Speed - Length between the 2 points - Source position (X, Y) - Destination position (X, Y) How can I calculate a position between the source and destion with these variables given? For example: source: 0, 0 destination: 10, 0 speed: 1 so after 1 second the players position would be 1, 0 The code below works but it's quite long so I'm looking for something shorter/more logical ====================================================================== I'm having a hard time figuring out how to calculate a new position of a player ingame. This code is server sided used to track a player(It's a emulator so I don't have access to the clients code). The collision detection of the server works fine I'm using bresenham's line algorithm and a raycast to determine at which point a collision happens. Once I deteremined the collision I calculate the length of the path the player is about to walk and also the total time. I would like to know the new position of a player each second. This is the code I'm currently using. It's in C++ but I am porting the server to C# and I haven't written the code in C# yet. // Difference between the source X - destination X //and source y - destionation Y float xDiff, yDiff; xDiff = xDes - xSrc; yDiff = yDes - ySrc; float walkingLength = 0.00F; float NewX = xDiff * xDiff; float NewY = yDiff * yDiff; walkingLength = NewX + NewY; walkingLength = sqrt(walkingLength); const float PI = 3.14159265F; float Angle = 0.00F; if(xDes >= xSrc && yDes >= ySrc) { Angle = atanf((yDiff / xDiff)); Angle = Angle * 180 / PI; } else if(xDes < xSrc && yDes >= ySrc) { Angle = atanf((-xDiff / yDiff)); Angle = Angle * 180 / PI; Angle += 90.00F; } else if(xDes < xSrc && yDes < ySrc) { Angle = atanf((yDiff / xDiff)); Angle = Angle * 180 / PI; Angle += 180.00F; } else if(xDes >= xSrc && yDes < ySrc) { Angle = atanf((xDiff / -yDiff)); Angle = Angle * 180 / PI; Angle += 270.00F; } float WalkingTime = (float)walkingLength / (float)speed; bool Done = false; float i = 0; while(i < walkingLength) { if(Done == true) { break; } if(WalkingTime >= 1000) { Sleep(1000); i += speed; WalkTime -= 1000; } else { Sleep(WalkTime); i += speed * WalkTime; WalkTime -= 1000; Done = true; } if(Angle >= 0 && Angle < 90) { float xNew = cosf(Angle * PI / 180) * i; float yNew = sinf(Angle * PI / 180) * i; float NewCharacterX = xSrc + xNew; float NewCharacterY = ySrc + yNew; } I have cut the last part of the loop since it's just 3 other else if statements with 3 other angle conditions and the only change is the sin and cos. The given speed parameter is the speed/second. The code above works but as you can see it's quite long so I'm looking for a new way to calculate this. btw, don't mind the while loop to calculate each new position I'm going to use a timer in C# Thank you very much

MovieClip, counter almost working AS3

Unable to connect SQL Server instance from Visual Studio 2008 Version 9.0

- by salvationishere

I am getting the below error from VS on an 32-bit XP Professional server even though I set Tools-Options-Database Tools-Data Connections to "SIDEKICK", which is the name of my computer. In other words SIDEKICK should default to the full SQLSERVER. In other words, I want VS to use SQLSERVER instead of SQLSERVER EXPRESS. And I can clearly see my database both from VS in the Server Explorer and also in SSMS 2008. Furthermore, I can view the tables of this database in Server Explorer from VS. I do not get any build errors. And it looks like all of the naming is consistent in my web.config file. I am developing my website according to a Microsoft tutorial, so I should not be getting an error. Yet I get the following exception when I run this code below: CreateAccounts.aspx.cs file protected void CreateAccountButton_Click(object sender, EventArgs e) { MembershipCreateStatus createStatus; //This line below is where the exception occurs MembershipUser newUser = Membership.CreateUser(Username.Text, Password.Text, Email.Text, passwordQuestion, SecurityAnswer.Text, true, out createStatus); And here is what the exception looks like: System.Web.HttpException was unhandled by user code Message="Unable to connect to SQL Server database."

Pulling record from mySQL database only working for userid and not email

- by user2908467

This function works because I search by userid: private void showList_Click(object sender, EventArgs e) { int id = 0; for (int i = 0; i <= sqlClient.Count("UserList"); i++) { Dictionary<string, string> dik = sqlClient.Select("UserList", "userid = " + id); var lines = dik.Select(kv => kv.Key + ": " + kv.Value.ToString()); userList.AppendText(string.Join(Environment.NewLine, lines)); userList.AppendText(Environment.NewLine); userList.AppendText("--------------------------------------"); id++; } } This function does not work because I search by email: private void login_Click(object sender, EventArgs e) { string email = lemail.Text; Dictionary<string, string> dik = sqlClient.Select("UserList", "firstname = " + email); var lines = dik.Select(kv => kv.Key + ": " + kv.Value.ToString()); logged.AppendText(string.Join(Environment.NewLine, lines)); } This is the error message I receive when I click on the login button: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '@aol.com' at line 1 The email I searched for in the database was "[email protected]" without quotes. I'm lead to believe by the error message the @ sign is causing conflict as I know it is a special character but I am having a hard time figuring out what phrase to search for to help me. Also, here is the function that is being called: public Dictionary<string, string> Select(string table, string WHERE) { //This methods selects from the database, it retrieves data from it. //You must make a dictionary to use this since it both saves the column //and the value. i.e. "age" and "33" so you can easily search for values. //Example: SELECT * FROM names WHERE name='John Smith' // This example would retrieve all data about the entry with the name "John Smith" //Code = Dictionary<string, string> myDictionary = Select("names", "name='John Smith'"); //This code creates a dictionary and fills it with info from the database. string query = "SELECT * FROM " + table + " WHERE " + WHERE + ""; Dictionary<string, string> selectResult = new Dictionary<string, string>(); if (this.Open()) { MySqlCommand cmd = new MySqlCommand(query, conn); MySqlDataReader dataReader = cmd.ExecuteReader(); try { while (dataReader.Read()) { for (int i = 0; i < dataReader.FieldCount; i++) { selectResult.Add(dataReader.GetName(i).ToString(), dataReader.GetValue(i).ToString()); } } dataReader.Close(); } catch { } this.Close(); return selectResult; } else { return selectResult; } } My database table is called "UserList" The fields in order are as follows: userid, email, password, lastname, firstname Any help would be greatly appreciated.

Is it possible to call Javascript's onsubmit event programatically on a form?

- by hoyhoy

In Ruby on Rails, I'm attempting to update the innerHTML of a div tag using the form_remote_tag helper. This update happens whenever an associated select tag receives an onchange event. The problem is, <select onchange="this.form.submit();">; doesn't work. Nor does document.forms[0].submit(). The only way to get the onsubmit code generated in the form_remote_tag to execute is to create a hidden submit button, and invoke the click method on the button from the select tag. Here's a working ERb partial example. <% form_remote_tag :url => product_path, :update => 'content', :method => 'get' do -%> <% content_tag :div, :id => 'content' do -%> <%= select_tag :update, options_for_select([["foo", 1], ["bar", 2]]), :onchange => "this.form.commit.click" %> <%= submit_tag 'submit_button', :style => "display: none" %> <% end %> <% end %> What I want to do is something like this, but it doesn't work. <% form_remote_tag :url => product_path, :update => 'content', :method => 'get' do -%> <% content_tag :div, :id => 'content' do -%> # the following line does not work <%= select_tag :update, options_for_select([["foo", 1], ["bar", 2]]), :onchange => "this.form.onsubmit()" %> <% end %> <% end %> So, is there any way to remove the invisible submit button for this use case? There seems to be some confusion. So, let me explain. The basic problem is that submit() doesn't call the onsubmit() code rendered into the form. The actual HTML form that Rails renders from this ERb looks like this: <form action="/products/1" method="post" onsubmit="new Ajax.Updater('content', '/products/1', {asynchronous:true, evalScripts:true, method:'get', parameters:Form.serialize(this)}); return false;"> <div style="margin:0;padding:0"> <input name="authenticity_token" type="hidden" value="4eacf78eb87e9262a0b631a8a6e417e9a5957cab" /> </div> <div id="content"> <select id="update" name="update" onchange="this.form.commit.click"> <option value="1">foo</option> <option value="2">bar</option> </select> <input name="commit" style="display: none" type="submit" value="submit_button" /> </div> </form> I want to axe the invisible submit button, but using a straight form.submit appears to not work. So, I need some way to call the form's onsubmit event code. Update: Orion Edwards solution would work if there wasn't a return(false); generated by Rails. I'm not sure which is worse though, sending a phantom click to an invisible submit button or calling eval on the getAttribute('onsubmit') call after removing the return call with a javascript string replacement!
