  • When I try to pass large amounts of information using jquery $.ajax(post) method. it throws potenti

    - by dotnetrocks
    I am trying to create a preview window for my texteditor in my blog page. I need to send the content to the server to clean up the text entered before I can preview it on the preview window. I was trying to use $.ajax({ type: method, url: url, data: values, success: LoadPageCallback(targetID), error: function(msg) { $('#' + targetID).attr('innerHTML', 'An error has occurred. Please try again.'); } }); Whenever I tried to click on the preview button it returns an XMLHTTPRequest error. The error description - Description: Request Validation has detected a potentially dangerous client input value, and processing of the request has been aborted. This value may indicate an attempt to compromise the security of your application, such as a cross-site scripting attack. You can disable request validation by setting validateRequest=false in the Page directive or in the configuration section. However, it is strongly recommended that your application explicitly check all inputs in this case. The ValidateRequest for the page is set to false. Is there a way I can set validaterequest to false for the ajax call.Please advise Thank you for reading my post.

  • Set Mime_type validation in Symfony

    - by Ngu Soon Hui
    I want to make sure that during file upload time, only the file of the format jpeg, png and gif are allowed. So the "File of type:" below in the screenshot must show jpeg, png and gif: I did the following for my validator in Symfony: $this->setValidator ( 'upload your filehere', new sfValidatorFile ( array ( 'required'=>true, 'mime_types' => array ('image/jpeg, image/png, image/gif' ) ) , array( 'mime_types'=> 'only jpeg' ) ) ); but when I click on the upload button, the files are not filtered accordingly; what did I do wrong? I also try $this->setValidator ( 'upload your filehere', new sfValidatorFile ( array ( 'required'=>true, 'mime_types' => 'image/jpeg, image/png, image/gif' ) , array( 'mime_types'=> 'only jpeg' ) ) ); But it doesn't work, too. I tried the following in my form class, but unfortunately it doesn't work as well: <?php class UploadCaseForm extends sfForm { public function configure() { $this->setWidgets ( array ('Documents' => new sfWidgetFormInputFile ( ) ) ); $this->widgetSchema->setNameFormat ( 'UploadCase[%s]' ); $this->validatorSchema ['Documents'] = new sfValidatorFile ( array ('mime_types' => 'web_images' ), array ('invalid' => 'Invalid file.', 'required' => 'Select a file to upload.', 'mime_types' => 'The file must be of JPEG, PNG or GIF format.' ) ); } } ?> Here's the action code: public function executeIndex(sfWebRequest $request) { $this->form = new UploadCaseForm ( ); if ($this->getRequest ()->getMethod () == sfRequest::POST) { var_dump($request->getParameter('UploadCase')); } } Edit: The accepted answer is the answer, as far as the server side validation goes. If anyone wants a client side validation, i.e., filtering the type of file that can be uploaded even before the operation hits server, then maybe there is no reliable way to do it, because of browser's constraint.

  • Is there a way to reload the page after <fb:like> is clicked?

    - by joon
    Hi, I'm wondering about this: I have a simple facebook-connect app that will only show certain content after you login and liked a certain page. It works (huzzah!) but I want to make it more user friendly by making it refresh automatically after you pressed the like button. Here's some code: <?php if ($me) { $pageid = -----------; $uid = $me['id']; $likeID = $facebook->api( array( 'method' => 'fql.query', 'query' => 'SELECT target_id FROM connection WHERE source_id = ' . $uid . ' AND target_id = ' . $pageid ) ); if ( empty($likeID) ) { // Person is LOGGED IN, but has NOT LIKED echo '<script src="MY WEBPAGE"></script><fb:like href="MY WEBPAGE" layout="box_count" show_faces="false" width="450"></fb:like>'; } else { // Person is LOGGED IN, and has LIKED, score! echo 'Download link'; } } else { // Person is NOT LOGGED IN, so we know NOTHING echo '<script src="MY WEBPAGE"></script><fb:like href="MY WEBPAGE" layout="box_count" show_faces="false" width="450"></fb:like>'; } ?> Is there anything I can do to this code (maybe in the fb:like tag?) that makes it reload the page after a like? Thanks.

  • TreeView update bug in the VB.NET

    - by CFP
    Consider the following code: Dim Working As Boolean = False Private Sub TreeView1_AfterCheck(ByVal sender As Object, ByVal e As System.Windows.Forms.TreeViewEventArgs) Handles TreeView1.AfterCheck If Working Then Exit Sub Working = True e.Node.Checked = Not e.Node.Checked Working = False End Sub Private Sub TreeView1_MouseClick(ByVal sender As System.Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles TreeView1.MouseClick If e.Button = Windows.Forms.MouseButtons.Right Then MsgBox("Checked = " & TreeView1.SelectedNode.Checked) End Sub Where TreeView1 is a TreeView added to the form, with CheckBoxes set to true and one node added. The code basically cancel any node checking occuring on the form. Single-clicking the top node to check it works well : your click is immediately canceled. Yet if you double-click the checkbox, it will display a tick. But verifying the check state through a right click will yield a Checked = False dialog. How come? Is it a bug (I'm using the latest .Net Framework 4.0, and he same occurs in 2.0), or am I doing something wrong here? Is there a work around? Thanks! EDIT: Additionally, the MouseDoubleClick event is not raised before you click once again. EDIT 2: Posted a bug report at Microsoft Connect

  • My Local Fileshare ClickOnce Update Is Not Working, Help?

    - by Soo
    I have a C# application that I'm trying to get to update automatically via ClickOnce. After publishing newer versions of software, I see the new versions in my publish folder, but when I open the application, it checks for updates, and does nothing (even though there are new files in the publish folder). What do I need in place for updates to be made automatically? Edit What version of Visual Studio are you using? Visual Studio 2008 Are you deploying the upgrades to the same location as the old version? They are being published to the same location (not sure about deployed) Is the installation URL the same? Have you incremented the version number? Yes In the Updates dialog reached by clicking the Updates button in the Publish page, do you have "The application should check for updates" checked? Yes Do you have "Before the application starts" selected? Yes How are you deploying the files? Not sure Are you copying them over to the file share or publishing the directly? Publishing directly

  • Slow Response in checkbox using JQuery

    - by Dean
    Hi to all. I'm trying to optimize a website. The flow is i tried to query a certain table and all of its data entry in a page(w/ toolbars), work fine. When i tried to edit the page the problem is when i click the checkbox button i have to wait 2-5sec just by clicking it. I limit the viewing of entry to 5 only but the response on checkbox doesn't change. The tables have 100 entries in them. function checkAccess(celDiv,id) { var celValue = $(celDiv).html(); if (celValue==1) $(celDiv).html("<input type='checkbox' value='"+$(celDiv).html()+"' checked disabled>") else $(celDiv).html("<input type='checkbox' value='"+$(celDiv).html()+"' disabled>") $(celDiv).click ( function() { $('input',this).each( function(){ tr_idx = $('#detFlex1 tbody tr').index($(this).parent().parent().parent()); td_idx = $('#detFlex1 tbody tr:eq('+tr_idx+') td').index($(this).parent().parent()); td_last = 13; for(var td=td_idx+1; td<=td_last;td++) { if ($(this).attr('checked') == true) { df[0].rows[tr_idx].cell[td_idx] = 1;//index[1] = Full Access if (td_idx==3) { df[0].rows[tr_idx].cell[td] = 1; } df[0].rows[tr_idx].cell[2] = 1; if (td_idx > 3) { df[0].rows[tr_idx].cell[2] = 1; } } else { df[0].rows[tr_idx].cell[td_idx] = 0;//index[0] = With Access if (td_idx==2) { df[0].rows[tr_idx].cell[td] = 0; } else if (td_idx==3) { df[0].rows[tr_idx].cell[td] = 0; } if (td_idx > 3) { df[0].rows[tr_idx].cell[3] = 0; } } } $('#detFlex1').flexAddData(df[0]); $('.toolbar a[title=Edit Item]').trigger('click'); }); } ); } I've thought that the problem is this above code. Could anyone help me simplify this code.?

  • Using input type="submit" to change content

    - by Conti
    Okay, I'm pretty sure I'm missing something very obvious here, but I just couldn't find a proper solution so far. What I'm trying to do is simple: Have a user write something into a form, have him submit the form, and write that input into a textarea on the same page. This is my code: <html><head></head> <body> <form name='registration'> <label for="input">Input:</label> <input type="text" id="input"/> <input type="submit" id="submit" value="Submit" onclick="execute()"/> </form> <div id="results"> <span>Result</span> <span><textarea cols="30" rows="5" id="resulttext" readonly="readonly"></textarea> </span> </div> <script> function execute() { var result = document.getElementById("input").value document.getElementById("resulttext").value=result; } </script> </body> </html> Now what happens if I enter something into the form is that the textarea briefly shows my input before reverting back to showing nothing. My guess is that the textarea field is only changed for the duration of the execute() function. When I change input type="submit" to a <button> everything works as intended, but I'm pretty sure I'm not supposed to do that.

  • Can I share code & resources between Android projects without using a library?

    - by Tom
    The standard advice for sharing code & resources between Android projects is to use a library. Personally I find this works poorly if (a) the shared code changes a lot, or (b) your computer isn't fast enough. I also don't want to get into deploying multiple APK's, which seems to be necessary when I use dependent projects (i.e. Java Build Path, Projects Tab). On the other hand, sharing a folder of source code by using the Eclipse linked source feature works great (Java Build Path, Source tab, Link Source button), but for these two issues: 1) I can't use the same technique to share resources. I can create the link to the resources parent folder but then things get wonky and the shared resources don't get compiled (I'm using ADT 21). 2) So then I settle for copying the shared resources into each project, but this doesn't work because either. The shared code can't import the copy of its resources because it doesn't know the package name of the project that uses it. The solution I've been using is to access the resources dynamically, but that has become cumbersome as the number of resources grows. So, I need a solution to either (1) or (2), or I'll have to go back to a library project. (Or maybe there is another option I haven't thought of?)

  • Problem with making a simple JS XmlHttpRequest call

    - by recipriversexclusion
    I have to create a very simple client that makes GET and POST calls to our server and parses the returned XML. I am writing this in JavaScript, problem is I don't know how to program in JS (started to look into this just this morning)! As n initial test, I am trying to ping to the Twitter API, here's the function that gets called when user enters the URL http://api.twitter.com/1/users/lookup.xml and hits the submit button: function doRequest() { var req_url, req_type, body; req_url = document.getElementById('server_url').value; req_type = document.getElementById('request_type').value; alert("Connecting to url: " + req_url + " with HTTP method: " + req_type); req = new XMLHttpRequest(); req.open(req_type, req_url, false, "username", "passwd");// synchronous conn req.onreadystatechange=function() { if (req.readyState == 4) { alert(req.status); } } req.send(null); } When I run this on FF, I get a Access to restricted URI denied" code: "1012 error on Firebug. Stuff I googled suggested that this was a FF-specific problem so I switched to Chrome. Over there, the second alert comes up, but displays 0 as HTTP status code, which I found weird. Can anyone spot what the problem is? People say this stuff is easier to use with JQuery but learning that on top of JS syntax is a bit too much now.

  • Winforms App Not Displaying Graphical Elements in Design Mode

    - by Sev
    I wrote a bunch of code in the .cs file in c# for a winforms application. The application runs fine, and everything is in it's place. Something like this: using.. namespace Temp { public class Temp : Form { Button b1; TextBox t1; Temp() { b1.Text = "Some Text"; b1.Size = new Size(50,20); ... } void function1() { // stuff } static void Main() { Application.Run(new Temp()); } } } How can I modify my code (or fix it somehow) so that the design view displays the elements in their correct positions and view so that I can visually edit them instead of having to trial/error everything. Edit for Clarification My application runs fine. The problem is, that I didn't use designer to create the application and so in the designer view, the app is empty. But not empty when I run it, since everything is positioned programmatically in the .cs file. My question is, how can I fix this, so that the designer shows the objects correctly. There is no quick fix other than to redesign everything?

  • How to get JTree expanded?

    - by Dzmitry Zhaleznichenka
    I have a wizard with several screens where user has to fill his/her details for further processing. At the second screen I have a radio group with three radio buttons that enable additional elements. To proceed, user has to choose one of them. When user selects third button, single-selection JTree filled in with data enables and user has to select an option from it. Then user has to press "Next" to get to next screen. The option he\she had selected is stored as a TreePath. So far so good. My problem is the following. If the user wants to come back from the following screen to the screen with a JTree, I want to provide him\her with the JTree expanded to the option that had been selected and to highlight the option. However, whatsoever I try to do for that (any combinations of expandPath, scrollPathToVisible, addSelectionPath, makeVisible) always provides me with a collapsed tree. I try to expand both leaves and nodes. My code looks like this: rbProcessJTree.setSelected(isProcessJTree()); if (null != getSelectedTablePath()){ trTables.addSelectionPath(getSelectedTablePath()); trTables.expandPath(getSelectedTablePath()); trTables.scrollPathToVisible(getSelectedTablePath()); } When setSelected() is called, state change listener is invoked that enables JTree. The model is loaded during the form initialization. Each time I switch between screens, I save the input data from previous screen and dispose it. Then, when I need to open previous screen back, I save data from the following screen, dispose it, load data to this screen and show it. So each time the screen is generating from scratch. Could you please explain, what sequence of operations has to be done to get JTree expanded in a newly created form,with data model loaded and selection path provided?

  • Using h:outputFormat to message-format the f:selectItems of a h:selectOneRadio

    - by msharma
    I am having some trouble with using h:selectOneRadio. I have a list of objects which is being returned which needs to be displayed. I am trying something like this: <h:selectOneRadio id="selectPlan" layout="pageDirection"> <f:selectItems value="#{detailsHandler.planList}" /> </h:selectOneRadio> and planList is a List of Plans. Plan is defined as: public class Plan { protected String id; protected String partNumber; protected String shortName; protected String price; protected boolean isService; protected boolean isOption; //With all getters/setters } The text that must appear for each radio button is actually in a properties file, and I need to insert params in the text to fill out some value in the bean. For example the text in my properties file is: plan_price=The price of this plan is {0}. I was hoping to do something like this: <f:selectItems value="<h:outputFormat value="#{i18n.plan_price}"> <f:param value="#{planHandler.price}"> </h:outputFormat>" /> Usually if it's not a h:selectOneRadio component, if it's just text I use the h:outputFormat along with f:param tags to display the messages in my .property file called i18n above, and insert a param which is in the backing bean. here this does not work. Does anyone have any ideas how I can deal with this? I am being returned a list of Plans each with their own prices and the text to be displayed is held in property file. Any help much appreciated. Thanks!

  • Ajax response takes time and status is 503

    - by Suresh S
    guys, i have a html page where onclick of a button a ajax request is sent to server , the request calls a jsp page which runs an oracle procedure.The procedure runs the logic and places it in a temp table . once procedure is completed , the values are returned to the client by selecting values from tmp table. as the response is too late . the data is not received at the client side. solution: i tried to run the procedure in a separate thread using a ajax call. when the procedure is completed a global flag is set to indicate that the data is generated. if the response is 500 , a second ajax call invoked by timeout function after 10000 ms . the second call checks the global flag ,if true then reads from table and sends the response. if not again a timeout is set at the client side. this solution is not mature enough. , as the procedure may take long time to respond. please let me know a good solution for this problenm?

  • Proper Memory Management for Objective-C Method

    - by Justin
    Hi, I'm programming an iPhone app and I had a question about memory management in one of my methods. I'm still a little new to managing memory manually, so I'm sorry if this question seems elementary. Below is a method designed to allow a number pad to place buttons in a label based on their tag, this way I don't need to make a method for each button. The method works fine, I'm just wondering if I'm responsible for releasing any of the variables I make in the function. The application crashes if I try to release any of the variables, so I'm a little confused about my responsibility regarding memory. Here's the method: FYI the variable firstValue is my label, it's the only variable not declared in the method. -(IBAction)inputNumbersFromButtons:(id)sender { UIButton *placeHolderButton = [[UIButton alloc] init]; placeHolderButton = sender; NSString *placeHolderString = [[NSString alloc] init]; placeHolderString = [placeHolderString stringByAppendingString:firstValue.text]; NSString *addThisNumber = [[NSString alloc] init]; int i = placeHolderButton.tag; addThisNumber = [NSString stringWithFormat:@"%i", i]; NSString *newLabelText = [[NSString alloc] init]; newLabelText = [placeHolderString stringByAppendingString:addThisNumber]; [firstValue setText:newLabelText]; //[placeHolderButton release]; //[placeHolderString release]; //[addThisNumber release]; //[newLabelText release]; } The application works fine with those last four lines commented out, but it seems to me like I should be releasing these variables here. If I'm wrong about that I'd welcome a quick explanation about when it's necessary to release variables declared in functions and when it's not. Thanks.

    Let's say I have these 2 tables QuesType and Ques:- QuesType QuestypeID|QuesType |Active ------------------------------------ 101 |QuesType1 |True 102 |QuesType2 |True 103 |XXInActiveXX |False Ques QuesID|Ques|Answer|QUesTypeID|Active ------------------------------------ 1 |Ques1|Ans1 |101 |True 2 |Ques2|Ans2 |102 |True 3 |Ques3|Ans3 |101 |True In the QuesType Table:- QuesTypeID is a Primary key In the Ques Table:- QuesID is a Primary key and QuesType ID is the Foreign Key that refernces QuesTypeID from QuesType Table Now I am unable to delete records from QuesType Table, I can only make QuesType inactive by setting Active=False. I am unable to delete QuesTypes permanently because of the Foreign key relation it has with Ques Table. So , I just set the column Active=false and those Questypes then don't show on my grid wen its binded. What I want to do is be able to delete any QuesType permamnently. Now it can only be deleted if its not being used anywhere in the Ques table, right? So to delete any QuesType permanently I thot this is what I could do:- In the grid that displays QuesTypes, I have this check box for Active and a button for delete.What I thot was, when a user makes some QuesType inactive then OnCheckChanged() event will run and that will have the code to delete all the Questions in Ques table that are using that QuesTypeID. Then on the QuesType grid, that QuesType would show as Deactivated and only then can a user delete it permanently. Am I thinking correctly? Currently in my DeleteQuesType Stored Procedure what I am doing is:- Setting the Active=false and Setting QuesTye= some string like XXInactiveXX Is there any other way?

  • HTML dynamic tags insert looks different compared to static layout

    - by Andrew Florko
    I program HTML interface with jquery. There is editable list of publications on the page and user can click any publication to edit details. Popup window appears with data and there is list of authors embedded into details form. There are edit/delete buttons against every of them + "add new author" button. User manipulates authors without page reload. When I insert a new author there are new edit/delete buttons created dynamically & embedded into page. I insert tags like this: <td class="author-actions"> <img onclick='edit(id)' .../> <img onclick='delete(id)' .../> </td> Just the same html-layout that is sent from web-server when popup window appears. But somehow it looks different. There is extraspace between images though firebug demonstrates the same css attributes applied. If I select with mouse inserted layout with IE, somehow it can reorder and become the same-looklike as the those, send by web-server. What can it be?

  • Visual C# Winforms App Not Displaying Graphical Elements in Design Mode

    - by Sev
    I wrote a bunch of code in the .cs file in c# for a winforms application. The application runs fine, and everything is in it's place. Something like this: using.. namespace Temp { public class Temp : Form { Button b1; TextBox t1; Temp() { b1.Text = "Some Text"; b1.Size = new Size(50,20); ... } void function1() { // stuff } static void Main() { Application.Run(new Temp()); } } } How can I modify my code (or fix it somehow) so that the design view displays the elements in their correct positions and view so that I can visually edit them instead of having to trial/error everything. Edit for Clarification My application runs fine. The problem is, that I didn't use designer to create the application and so in the designer view, the app is empty. But not empty when I run it, since everything is positioned programmatically in the .cs file. My question is, how can I fix this, so that the designer shows the objects correctly. There is no quick fix other than to redesign everything?
