  • Problem in encoding and decoding the string in Iphone sdk

    - by monish
    HI Guys, Here I am having a problem In encoding/decoding the strings. Actually I had a string which I am encoding it using the base64.which was working fine. And now I need to decode the string that was encoded before and want to print it. I code I written as: I imported the base64.h and base64.m files into my application which contains the methods as: + (NSData *) dataWithBase64EncodedString:(NSString *) string; - (id) initWithBase64EncodedString:(NSString *) string; - (NSString *) base64EncodingWithLineLength:(unsigned int) lineLength; And the code in my view controller where I encode the String is: - (id)init { if (self = [super init]) { // Custom initialization userName = @"Sekhar"; password = @"Bethalam"; } return self; } -(void)reloadView { NSString *authStr = [NSString stringWithFormat:@"%@:%@",userName,password]; NSData *authData = [authStr dataUsingEncoding:NSASCIIStringEncoding]; NSString *authValue = [NSString stringWithFormat:@"%@", [authData base64EncodingWithLineLength:30]]; NSLog(authValue); //const char *str = authValue; //NSString *decStr = [StringEncryption DecryptString:authValue]; //NSLog(decStr); //NSData *decodeData = [NSData decode:authValue]; //NSString *decStr = [NSString stringWithFormat:@"%@",decodeData]; //NSStr //NSLog(decStr); } -(void)viewWillAppear:(BOOL)animated { [self reloadView]; } and now I want to decode the String that I encoded. But I dont know How to do that.can anyone suggest me with code how to get it. Anyone's help will be much appreciated. Thank you, Monish.

  • Checkbox does not change when clicked directly on it

    - by Matt McCormick
    I have a table of data and have one checkbox per row for the user to select the item. I'm using the following jQuery code to allow the user to select the item by clicking anywhere in the row: $("tbody tr").click(function() { var checkbox = $(this).find(':checkbox'); checkbox.attr('checked', !checkbox.attr('checked')); }); The problem is if I click directly on the checkbox, nothing happens. ie. if the checkbox is not checked, it remains unchecked. If I click anywhere else in the row, the checkbox changes status. I'm thinking that the jQuery code is causing the action to be performed twice. If I click on the checkbox, the checkbox will change but then the jQuery code for clicking on the row will be performed and the checkbox will be changed back. Not sure if that is actually happening but that is my guess. How can I get a checkbox to be toggled when a user clicks on a row and the same thing if they click directly on the checkbox?

  • PHP: How To Integrate HTML Purifier To Fileter User Submitted Data?

    - by TaG
    I have this script that collects data from users and I wanted to check their data for malicious code like XSS and SQL injections by using HTML Purifier http://htmlpurifier.org/ but how do I add it to my php form submission script? Here is my HTML purifier code require_once '../../htmlpurifier/library/HTMLPurifier.auto.php'; $config = HTMLPurifier_Config::createDefault(); $config->set('Core.Encoding', 'UTF-8'); // replace with your encoding $config->set('HTML.Doctype', 'XHTML 1.0 Strict'); // replace with your doctype $purifier = new HTMLPurifier($config); $clean_html = $purifier->purify($dirty_html); Here is my PHP form submission code. if (isset($_POST['submitted'])) { // Handle the form. $mysqli = mysqli_connect("localhost", "root", "", "sitename"); $dbc = mysqli_query($mysqli,"SELECT users.*, profile.* FROM users INNER JOIN contact_info ON contact_info.user_id = users.user_id WHERE users.user_id=3"); $about_me = mysqli_real_escape_string($mysqli, $_POST['about_me']); $interests = mysqli_real_escape_string($mysqli, $_POST['interests']); if (mysqli_num_rows($dbc) == 0) { $mysqli = mysqli_connect("localhost", "root", "", "sitename"); $dbc = mysqli_query($mysqli,"INSERT INTO profile (user_id, about_me, interests) VALUES ('$user_id', '$about_me', '$interests')"); } if ($dbc == TRUE) { $dbc = mysqli_query($mysqli,"UPDATE profile SET about_me = '$about_me', interests = '$interests' WHERE user_id = '$user_id'"); echo '<p class="changes-saved">Your changes have been saved!</p>'; } if (!$dbc) { // There was an error...do something about it here... print mysqli_error($mysqli); return; } }

  • aspnet_compiler -fixednames does not work?

    - by Terrence
    I am unable to get the -fixednames switch to create dlls for the cs code behind files. The files in the bin folder are compiled aspx pages, but the code behind files are all compiled into one large websitename.dll file. Here is my command with switches. aspnet_compiler -v / -p E:\Source\DotNet4\mysolution\website -f -d -fixednames E:\Source\DotNet4\CompiledWebSite This produces many files in the bin folder. website.dll and website.pdb (contains code behind) myform1.aspx.643c7876.dll (compiled aspx layout ui) I have tested this over and over to make sure I am not missing anything. The test is place a label on myform1.aspx, and in the codebehind populate the label with some text. Compile the website with the above switches and deploy the website. Make a change to the myform1 codebehind and change the label text. Compile and only deploy the myform1.aspx.643c7876.dll to the website. Result: label is still the same. Now deploy the website.dll and pdb and the label changes. Can anyone tell me how to get -fixednames to create sinle dlls for codebehind?

  • Help with my PHP template class

    - by blerh
    I want to separate the output of HTML from my program code in my projects, so I wrote a very simple database class. <?php class Template { private $template; function load($filePath) { if(!$this->template = file_get_contents($filePath)) $this->error('Error: Failed to open <strong>' . $filePath . '</strong>'); } function replace($var, $content) { $this->template = str_replace("{$var}", $content, $this->template); } function display() { echo $this->template; } function error($errorMessage) { die('die() by template class: <strong>' . $errorMessage . '</strong>'); } } ?> The thing I need help with is the display() method. Say for example I use this code: $tplObj = new Template(); $tplObj->load('index.php'); $tplObj->replace('{TITLE}', 'Homepage'); $tplObj->display(); And the index.php file is this: <html> <head> <title>{TITLE}</title> </head> <body> <h1>{TITLE}</h1> <?php if($something) { echo '$something is true'; } else { echo '$something is false'; } ?> </body> </html> I'm just wondering if the PHP code in there would be run? Or would it just be sent to the browser as plaintext? I was using eval() in my template class but I hate that function :P Thanks.

  • How do I lookup a JNDI Datasource from outside a web container?

    - by masotime
    I have the following environment set up: Java 1.5 Sun Application Server 8.2 Oracle 10 XE Struts 2 Hibernate I'm interested to know how I can write code for a Java client (i.e. outside of a web application) that can reference the JNDI datasource provided by the application server. The ports for the Sun Application Server are all at their defaults. There is a JNDI datasource named jdbc/xxxx in the server configuration, but I noticed that the Hibernate configuration for the web application uses the name java:comp/env/jdbc/xxxx instead. Most of the examples I've seen so far involve code like Context ctx = new InitialContext(); ctx.lookup("jdbc/xxxx"); But it seems I'm either using the wrong JNDI name, or I need to configure a jndi.properties or other configuration file to correctly point to a listener? I have appserv-rt.jar from the Sun Application Server which has a jndi.properties inside of it, but it does not seem to help. There's a similar question here, but it doesn't give any code / refers to having iBatis obtain the JNDI Datasource automatically: http://stackoverflow.com/questions/39053/accessing-datasource-from-outside-a-web-container-through-jndi

  • Custom QAbstractGraphicsShapeItem very slow in Qt Jambi

    - by Mene
    I try to implement an own QAbstractGraphicsShapeItem in Qt Jambi (4.5) but as soon as I implement a custom class (rather than use e.g. QGraphicsEllipseItem) the rendering speed drops by about on order of magnitude. If looked in the original Code of QGraphicsEllipseItem and it seems to do basicly the same. class Circle extends QAbstractGraphicsShapeItem { final private QRectF rect = new QRectF(); public final void setRect(double x, double y, double w, double h) { QRectF newRect = new QRectF(x, y, w, h); if (!newRect.equals(rect)) { prepareGeometryChange(); this.rect.setX(x); this.rect.setY(y); this.rect.setWidth(w); this.rect.setHeight(h); this.update(rect); } } @Override public final QRectF boundingRect() { return rect; } QPainterPath shape; @Override public final QPainterPath shape() { if (shape == null) { QPainterPath path = new QPainterPath(); path.addEllipse(rect); QPainterPathStroker stroker = new QPainterPathStroker(); QPen pen = this.pen(); stroker.setCapStyle(pen.capStyle()); stroker.setWidth(pen.widthF()); shape = stroker.createStroke(path); } return shape; } @Override public final void paint(QPainter painter, QStyleOptionGraphicsItem option, QWidget widget) { painter.setPen(this.pen()); painter.setBrush(this.brush()); painter.drawEllipse(this.rect); } } I need to render a lot of objects and they are mostly moving, so speed is essential. Anyone knows how to speed this up? I underestand that Java might be slower then the nativ code in the library. But the code in the paint method seems not to be the problem, since commenting it out doesn't change the speed notably.

  • Javascript: I can get the text of a selection, now how do I get the text outside the selection?

    - by DavidR
    I have a bit of code that returns the text of a selection and I can assign that string to a variable, but now all I need are two variables, one for the text before the selection and one for the text after the selection. Here is the code for getting the selection: function findSelection(){ //returns the selection object. var userSelection; if (window.getSelection) {userSelection = window.getSelection();} // Mozilla Selection object. else if (document.selection){userSelection = document.selection.createRange();} //gets Microsoft Text Range, should be second b/c Opera has poor support for it. if (userSelection.text){return userSelection.text} //for Microsoft Objects. else {return userSelection} //For Mozilla Objects. } Then I find the anchorOffset and focusOffset to find the caret positions. I tried using these to modify a range object, like this: var range = document.createRange(); range.setStart(textdiv,0); range.setEnd(textdiv,5); Where textdiv is a variable holding the last div the user clicked on. The problem is firefox just gives me a "Security error" code: "1000" at the line range.setStart(textdiv,0);. Is there an easier way to go about doing this? I really just need the text and nothing more.

  • Zend_Validate_Abstract custom validator not displaying correct error messages.

    - by Jeremy Dowell
    I have two text fields in a form that I need to make sure neither have empty values nor contain the same string. The custom validator that I wrote extends Zend_Validate_Abstract and works correctly in that it passes back the correct error messages. In this case either: isEmpty or isMatch. However, the documentation says to use addErrorMessages to define the correct error messages to be displayed. in this case, i have attached ->addErrorMessages(array("isEmpty"=>"foo", "isMatch"=>"bar")); to the form field. According to everything I've read, if I return "isEmpty" from isValid(), my error message should read "foo" and if i return "isMatch" then it should read "bar". This is not the case I'm running into though. If I return false from is valid, no matter what i set $this-_error() to be, my error message displays "foo", or whatever I have at index[0] of the error messages array. If I don't define errorMessages, then I just get the error code I passed back for the display and I get the proper one, depending on what I passed back. How do I catch the error code and display the correct error message in my form? The fix I have implemented, until I figure it out properly, is to pass back the full message as the errorcode from the custom validator. This will work in this instance, but the error message is specific to this page and doesn't really allow for re-use of code. Things I have already tried: I have already tried validator chaining so that my custom validator only checks for matches: ->setRequired("true") ->addValidator("NotEmpty") ->addErrorMessage("URL May Not Be Empty") ->addValidator([*customValidator]*) ->addErrorMessage("X and Y urls may not be the same") But again, if either throws an error, the last error message to be set displays, regardless of what the error truly is. I'm not entirely sure where to go from here. Any suggestions?

  • std::locale breakage on MacOS 10.6 with LANG=en_US.UTF-8

    - by fixermark
    I have a C++ application that I am porting to MacOSX (specifically, 10.6). The app makes heavy use of the C++ standard library and boost. I recently observed some breakage in the app that I'm having difficulty understanding. Basically, the boost filesystem library throws a runtime exception when the program runs. With a bit of debugging and googling, I've reduced the offending call to the following minimal program: #include <locale> int main ( int argc, char *argv [] ) { std::locale::global(std::locale("")); return 0; } This program fails when I run this through g++ and execute the resulting program in an environment where LANG=en_US.UTF-8 is set (which on my computer is part of the default bash session when I create a new console window). Clearing the environment variable (setenv LANG=) allows the program to run without issues. But I'm surprised I'm seeing this breakage in the default configuration. My questions are: Is this expected behavior for this code on MacOS 10.6? What would a proper workaround be? I can't really re-write the function because the version of the boost libraries we are using executes this statement internally as part of the filesystem library. For completeness, I should point out that the program from which this code was synthesized crashes when launched via the 'open' command (or from the Finder) but not when Xcode runs the program in Debug mode. edit The error given by the above code on 10.6.1 is: $ ./locale terminate called after throwing an instance of 'std::runtime_error' what(): locale::facet::_S_create_c_locale name not valid Abort trap

  • custom cells uitableview - cannot display all the rows

    - by Matt Facer
    Hi guys, I'm creating a uitableview with custom cells which I created in Interface Builder. There are currently three cells (UITableViewCell). I have a UITableView which is on the view. The code I have is fairly standard, but I cannot work out how to actually SHOW the three custom cells. I am using the cellForRowAtIndexPath method. My aim is to get a grouped uitableview which shows like the following Item - Name Settings - alert - time So the above indented view should be my grouped uitableview. The problem is, I cannot get it to show using code. The uitableview will ALWAYS be this. I am trying to replicate the settings style screen... so I do not have any arrays to display the uitableview cells. How do I actually display my three cells? I have the following code - (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView { return 2; } - (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section { if (section == 0) return 1; else return 2; } - (NSString *)tableView:(UITableView *)tableView titleForHeaderInSection:(NSInteger)section { if(section == 0) return @"Item"; else return @"Settings"; } So all I need to know is how to actually display my custom cells inside the tableview! Thanks for any information. I've searched for AGES in google .. all the tutorials use arrays to display data!

  • Ruby and duck typing: design by contract impossible?

    - by davetron5000
    Method signature in Java: public List<String> getFilesIn(List<File> directories) similar one in ruby def get_files_in(directories) In the case of Java, the type system gives me information about what the method expects and delivers. In Ruby's case, I have no clue what I'm supposed to pass in, or what I'll expect to receive. In Java, the object must formally implement the interface. In Ruby, the object being passed in must respond to whatever methods are called in the method defined here. This seems highly problematic: Even with 100% accurate, up-to-date documentation, the Ruby code has to essentially expose its implementation, breaking encapsulation. "OO purity" aside, this would seem to be a maintenance nightmare. The Ruby code gives me no clue what's being returned; I would have to essentially experiment, or read the code to find out what methods the returned object would respond to. Not looking to debate static typing vs duck typing, but looking to understand how you maintain a production system where you have almost no ability to design by contract. Update No one has really addressed the exposure of a method's internal implementation via documentation that this approach requires. Since there are no interfaces, if I'm not expecting a particular type, don't I have to itemize every method I might call so that the caller knows what can be passed in? Or is this just an edge case that doesn't really come up?

  • Python Post Upload JPEG to Server?

    - by iJames
    It seems like this answer has been provided a bunch of times but in all of it, I'm still getting errors from the server and I'm sure it has to do with my code. I've tried HTTP, and HTTPConnection from httplib and both create quite different terminal outputs in terms of formatting/encoding so I'm not sure where the problem lies. Does anything stand out here? Or is there just a better way? Pieced together from an ancient article because I really needed to understand the basis of creating the post: http://code.activestate.com/recipes/146306-http-client-to-post-using-multipartform-data/ Note, the jpeg is supposed to be "unformatted". The pseudocode: boundary = "somerandomsetofchars" BOUNDARY = '--' + boundary CRLF = '\r\n' fields = [('aspecialkey','thevalueofthekey')] files = [('Image.Data','mypicture.jpg','/users/home/me/mypicture.jpg')] bodylines = [] for (key, value) in fields: bodylines.append(BOUNDARY) bodylines.append('Content-Disposition: form-data; name="%s"' % key) bodylines.append('') bodylines.append(value) for (key, filename, fileloc) in files: bodylines.append(BOUNDARY) bodylines.append('Content-Disposition: form-data; name="%s"; filename="%s"' % (key, filename)) bodylines.append('Content-Type: %s' % self.get_content_type(fileloc)) bodylines.append('') bodylines.append(open(fileloc,'r').read()) bodylines.append(BOUNDARY + '--') bodylines.append('') #print bodylines content_type = 'multipart/form-data; boundary=%s' % BOUNDARY body = CRLF.join(bodylines) #conn = httplib.HTTP("www.ahost.com") # In both this and below, the file part was garbling the rest of the body?!? conn = httplib.HTTPConnection("www.ahost.com") conn.putrequest('POST', "/myuploadlocation/uploadimage") headers = { 'content-length': str(len(body)), 'Content-Type' : content_type, 'User-Agent' : 'myagent' } for headerkey in headers: conn.putheader(headerkey, headers[headerkey]) conn.endheaders() conn.send(body) response = conn.getresponse() result = response.read() responseheaders = response.getheaders() It's interesting in that the real code I've implemented seems to work and is getting back valid responses, but the problem it it's telling me that it can't find the image data. Maybe this is particular to the server, but I'm just trying to rule out that I'm not doing some thing exceptionally stupid here. Or perhaps there's other methodologies for doing this more efficiently. I've not tried poster yet because I want to make sure I'm formatting the POST correctly first. I figure I can upgrade to poster after it's working yes?

  • How do you print from a popup window in javascript?

    - by sglantz
    I have a .Net application that dynamically creates a small HTML page and pops it up in a new window using the javascript document.open method. Everything with that functionality is working fine. Now I want to add a button to the HTML page that prints the page. I have tried using the following code to no avail: <a href='print.html' onClick='window.print();return false;'> <img src='images/printer.png' height='32px' width='32px'></a> When the button is clicked in the popup window, nothing happens. But when the source code of of this page is saved and loaded in a browser as a separate page, the print button works perfectly. So it would appear that the problem is caused by the fact that the code is in a popup window. Does anyone know a way to fix this problem or any alternatives? EDIT: Other method that I have tried with the same results: <input type='button' onclick='window.print()' value='Print' /> and <a href='javascript:window.print()'> <img src='images/printer.png' height='32px' width='32px'></a>

  • How to add validation errors in the validation collection asp.net mvc?

    - by johndoe
    Inside my controller's action I have the following code: public ActionResult GridAction(string id) { if (String.IsNullOrEmpty(id)) { // add errors to the errors collection and then return the view saying that you cannot select the dropdownlist value with the "Please Select" option } return View(); UPDATE: if (String.IsNullOrEmpty(id)) { // add error ModelState.AddModelError("GridActionDropDownList", "Please select an option"); return RedirectToAction("Orders"); } } UPDATE 2: Here is my updated code: @Html.DropDownListFor(x => x.SelectedGridAction, Model.GridActions,"Please Select") @Html.ValidationMessageFor(x => x.SelectedGridAction) The Model looks like the following: public class MyInvoicesViewModel { private List<SelectListItem> _gridActions; public int CurrentGridAction { get; set; } [Required(ErrorMessage = "Please select an option")] public string SelectedGridAction { get; set; } public List<SelectListItem> GridActions { get { _gridActions = new List<SelectListItem>(); _gridActions.Add(new SelectListItem() { Text = "Export to Excel", Value = "1"}); return _gridActions; } } } And here is my controller action: public ActionResult GridAction(string id) { if (String.IsNullOrEmpty(id)) { // add error ModelState.AddModelError("SelectedGridAction", "Please select an option"); return RedirectToAction("Orders"); } return View(); } Nothing happens! I am totally lost on this one! UPDATE 3: I am now using the following code but still the validation is not firing: public ActionResult GridAction(string id) { var myViewModel= new MyViewModel(); myViewModel.SelectedGridAction = id; // id is passed as null if (!ModelState.IsValid) { return View("Orders"); }

  • singleton factory connection pdo

    - by Scarface
    Hey guys I am having a lot of trouble trying to understand this and I was just wondering if someone could help me with some questions. I found some code that is supposed to create a connection with pdo. The problem I was having was having my connection defined within functions. Someone suggested globals but then pointed to a 'better' solution http://stackoverflow.com/questions/130878/global-or-singleton-for-database-connection. My questions with this code are. PS I cannot format this code on this page so see the link if you cannot read What is the point of the connection factory? What goes inside new ConnectionFactory(...) When the connection is defined $db = new PDO(...); why is there no try or catch (I use those for error handling)? Does this then mean I have to use try and catch for every subsequent query? class ConnectionFactory { private static $factory; public static function getFactory() { if (!self::$factory) self::$factory = new ConnectionFactory(...); return self::$factory; } private $db; public function getConnection() { if (!$db) $db = new PDO(...); return $db; } } function getSomething() { $conn = ConnectionFactory::getFactory()-getConnection(); . . . }

  • sorting filtered data in asp.net listview

    - by user791345
    I've created a listview that's filled up with a list of guitars from the database on page load like so: protected void Page_Load(object sender, EventArgs e) { SqlConnection con = new SqlConnection(WebConfigurationManager.ConnectionStrings["GuitarsLTDBConnectionString"].ToString()); SqlCommand cmd = new SqlCommand("SELECT * FROM Guitars", con); SqlDataAdapter da = new SqlDataAdapter(cmd.CommandText, con); DataTable dt = new DataTable(); da.Fill(dt); lvGuitars.DataSource = dt; lvGuitars.DataBind(); } The following code filters that list of guitars by a certain Make when the user checks the checkbox corresponding to that make protected void chkOrgs_SelectedIndexChanged(object sender, EventArgs e) { DataTable dt = (DataTable)lvGuitars.DataSource; DataView dv = new DataView(dt); if (chkOrgs.SelectedValue == "Gibson") { dv.RowFilter = "Make = 'Gibson' OR Make='Fender'"; } lvGuitars.DataSource = dv.ToTable(); lvGuitars.DataBind(); } Now, what I want to do is be able to sort the latest data that is present within the listview. Meaning, if sort is clicked before filtering, the it should sort all data. If sort is clicked after filtering, it should sort the filtered data. I'm using the following code, which is triggered upon a LinkButton click protected void lnkSortResults_Click(object sender, EventArgs e) { DataTable dt = (DataTable)lvGuitars.DataSource; DataView dv = new DataView(dt); dv.Sort = "Make ASC"; lvGuitars.DataSource = dv.ToTable(); lvGuitars.DataBind(); } The problem is that all the data that the listview was loaded with before any filtering is sorted, and not the latest filtered data. How can I change this code so that the latest data available in the listview is the one that's sorted? Thanks

  • Codeigniter common templates

    - by Darthg8r
    Let's say that I have a website that has 100 different pages. Each page uses a common header and footer. Inside the header is some dynamic content that comes from a database. I'd like to avoid having to have code in every single controller and action that passes this common code into the view. function index() { // It sucks to have to include this on every controller action. data['title'] = "This is the index page"; data['currentUserName'] = "John Smith"; $this->load->view("main_view", data); } function comments() { // It sucks to have to include this on every controller action. data['title'] = "Comment list"; data['currentUserName'] = "John Smith"; $this->load->view("comment_view", data); } I realize that I could refactor the code so that the common parts are in a single function and the function is called by the action. Doing so would reduce SOME of the pain, but it still doesn't feel right since I'd still have to make a call to that function every time. What's the correct way to handle this?

  • How to minify JS in PHP easily...Or something else

    - by RickyAYoder
    I've done some looking around, but I'm still confused a bit. I tried Crockford's JSMin, but Win XP can't unzip the executable file for some reason. What I really want though is a simple and easy-to-use JS minifier that uses PHP to minify JS code--and return the result. The reason why is because: I have 2 files (for example) that I'm working between: scripts.js and scripts_template.js scripts_template is normal code that I write out--then I have to minify it and paste the minified script into scripts.js--the one that I actually USE on my website. I want to eradicate the middle man by simply doing something like this on my page: <script type="text/javascript" src="scripts.php"></script> And then for the contents of scripts.php: <?php include("include.inc"); header("Content-type:text/javascript"); echo(minify_js(file_get_contents("scripts_template.js"))); This way, whenever I update my JS, I don't have to constantly go to a website to minify it and re-paste it into scripts.js--everything is automatically updated. Yes, I have also tried Crockford's PHP Minifier and I've taken a look at PHP Speedy, but I don't understand PHP classes just yet...Is there anything out there that a monkey could understand, maybe something with RegExp? How about we make this even simpler? I just want to remove tab spaces--I still want my code to be readable. It's not like the script makes my site lag epically, it's just anything is better than nothing. Tab removal, anyone? And if possible, how about removing completely BLANK lines?

  • UnsupportedEncodingException thrown when using Resin and Grails

    - by knorv
    I've encountered a strange problem in a Grails webapp running under Grails: java.io.UnsupportedEncodingException is thrown quite frequently due to various unknown encoding strings (such as "ISO8859_10", "ISO-8859-10"), and the strange thing is that this is done entirely within the Resin and Grails code. That is - no custom code is involved when the exception is thrown. I'm not sure if it is Grails or the servlet container's code that should handle the exception. But I'd assume that the exception should be handled somewhere and not bubble up all the way to stderr. This is the exception in full: java.io.UnsupportedEncodingException: ISO-8859-10 at com.caucho.vfs.i18n.JDKWriter$OutputStreamEncodingWriter.<init>(JDKWriter.java:112) at com.caucho.vfs.i18n.JDKWriter.create(JDKWriter.java:79) at com.caucho.vfs.Encoding.getWriteEncoding(Encoding.java:231) at com.caucho.server.connection.ToByteResponseStream.setEncoding(ToByteResponseStream.java:137) at com.caucho.server.connection.AbstractHttpResponse.setLocale(AbstractHttpResponse.java:1683) at com.caucho.server.connection.HttpServletResponseImpl.setLocale(HttpServletResponseImpl.java: 115) at javax.servlet.ServletResponseWrapper.setLocale(ServletResponseWrapper.java:139) at javax.servlet.ServletResponseWrapper.setLocale(ServletResponseWrapper.java:139) at org.springframework.web.servlet.DispatcherServlet.render(DispatcherServlet.java:1035) at org.codehaus.groovy.grails.web.servlet.GrailsDispatcherServlet.doDispatch(GrailsDispatcherServlet.java:290) at org.springframework.web.servlet.DispatcherServlet.doService(DispatcherServlet.java:716) at org.springframework.web.servlet.FrameworkServlet.processRequest(FrameworkServlet.java:647) at org.springframework.web.servlet.FrameworkServlet.doGet(FrameworkServlet.java:552) at javax.servlet.http.HttpServlet.service(HttpServlet.java:114) My questions: Should the exception be handled? If so, is it the responsibility of the servlet container (Resin) or the web framework (Grails)? How would you go about solving this? (I'd rather not having the exception log cluttered with exceptions that I can do nothing about.)

  • Error with Property Validation in Form Submission in ASP.NET MVC

    - by Maxim Z.
    I have a simple form on an ASP.NET MVC site that I'm building. This form is submitted, and then I validate that the form fields aren't null, empty, or improperly formatted. However, when I use ModelState.AddModelError() to indicate validation errors from my controller code, I get an error when my view is re-rendered. In Visual Studio, I get that the following line is highlighted as being the location of the error: <%=Html.TextBox("Email")%> The error is the following: NullReferenceException was unhandled by user code - object reference not set to an instance of an object. My complete code for that textbox is the following: <p> <label for="Email">Your Email:</label> <%=Html.TextBox("Email")%> <%=Html.ValidationMessage("Email", "*") %> </p> Here's how I'm doing that validation in my controller: try { System.Net.Mail.MailAddress address = new System.Net.Mail.MailAddress(email); } catch { ModelState.AddModelError("Email", "Should not be empty or invalid"); } return View(); Note: this applies to all of my fields, not just my Email field, as long as they are invalid.

  • if/else statement in a function: using onclick as a switch

    - by Aurora Schmidt
    I have looked for solutions to this on google for what seems like an eternity, but I can't seem to formulate my search correctly, or nobody has posted the code I'm looking for earlier. I am currently trying to make a function that will modify one or several margins of a div element. I want to use an if/else statement within the function, so that the onclick event will switch between the two conditions. This is what I have been working on so far; function facebookToggle() { if($('#facebooktab').style.margin-left == "-250px";) { document.getElementById("facebooktab").style.marginLeft="0px"; } else { document.getElementById("facebooktab").style.marginLeft="-250px"; } } I have tried twisting it around a little, like switching between "marginLeft" and "margin-left", to see if I was just using the wrong terms.. I'm starting to wonder if it might not be possible to combine jQuery and regular javascript? I don't know.. It's all just guesses on my part at this point. Anyway, I have a div, which is now positioned (fixed) so almost all of it is hidden outside the borders of the browser. I want the margin to change onclick so that it will be fully shown on the page. And when it is shown, I want to be able to hide it again by clicking it. I might be approaching this in the wrong way, but I really hope someone can help me out, or even tell me another way to get the same results. Thank you for any help you can give me. You can see it in action at: http://www.torucon.no/test/ (EDIT: By the way, I am a complete javascript novice, I have no experience with javascript prior to this experiment. Please don't be too harsh, as I am aware I probably made some really stupid mistakes in this short code.) EDITED CODE: function facebookToggle() { if($('#facebooktab').css('margin-left', '-250px') { $('#facebooktab').css('margin-left', '0px'); } else { $('#facebooktab').css('margin-left', '-250px'); } }

  • How to use DLL reference with an ActiveX <object> via JavaScript

    - by John Factorial
    My question: how can I set an ActiveX object's property via JavaScript to an enum value found in a non-ActiveX DLL? Problem description: I am instantiating an ActiveX object with the following object tag: <object classid="clsid:F338193D-2491-4D7B-80CE-03487041A278" id="VideoCapture1" width="500" height="500"></object> (This is the guid for the 3rd party ActiveX I'm using, "VisioForge_Video_Capture_4.VFVideoCapture4X") I have example C# code for using this ActiveX, which I am porting to JavaScript. Code like this works just fine: VideoCapture1.Debug_Mode = true; var devcount = VideoCapture1.Video_CaptureDevices_GetCount(); var devs = []; for (var i =0; i < devcount; ++i) { devs[devs.length] = VideoCapture1.Video_CaptureDevices_GetItem(i); } ... etc ... However, VideoCapture1 has some settings which refer to a DLL enum, like so (C# code): VideoCapture1.Mode = VisioForge_Video_Capture_4.TxVFMode.Mode_Video_Preview; I can see in Visual Web Developer that TxVFMode.Mode_Video_Preview is value 1 in the enum. However, the following JS does not appear to set the Mode properly: VideoCapture1.Mode = 1; Does anyone know how I can set VideoCapture1.Mode to the enum value found in the TxVFMode? PS: In Visual Web Developer, when I "Go to definition" on TxVFMode, I get the Guid for the enum. I thought I could create an with this Guid or instantiate a VisioForge_Video_Capture_4.TxVFMode in JS, but neither gives me a usable object.

  • FileSystemWatcher does not fire when using C++ std::ofstream

    - by Adam Haile
    I'm trying to add a log monitor to an in-house test utility for a windows service I'm working on. The service is written in C++ (win32) and the utility is in .NET (C#) The log monitor works for many other C++ apps I've written, but not for my service. The only main difference I can see is that the other apps use the older ::WriteFile() to output to the log, whereas in the service I'm using std::ofstream like this: std::ofstream logFile; logFile.open("C:\\mylog.log"); logFile << "Hello World!" << std::endl; logFile.flush(); From my utility I use FileSystemWatcher like this: FileSystemWatcher fsw = new FileSystemWatcher(@"C:\", "mylog.log"); fsw.Changed += new FileSystemEventHandler(fsw_Handler); fsw.EnableRaisingEvents = true; But for the service, it never gets any change events as the log is updated. I've found that any example code using FileSystemWatcher I've come across online has the same exact issue as well... But, I know the events should be available because other log monitor apps (like BareTail) work fine with the service log file. I'd rather get the C# code for the utility to just work so it works with anything, but if I have to change the logging code for the service I will. Does anyone see what's going wrong here?
