  • Preventing a security breach

    - by Wiz
    I am creating a website where you "post", and the form content is saved in a MySql database, and upon loading the page, is retrieved, similar to facebook. I construct all the posts and insert raw html into a template. The thing is, as I was testing, I noticed that I could write javascript or other HTML into the form and submit it, and upon reloading, the html or JS would treated as source code, not a post. I figured that some simple encoding would do the trick, but using is not working. Is there an efficient way to prevent this type of security hole?

  • Transform shape built of contour splines to simple polygons

    - by Cheery
    I've dumped glyphs from truetype file so I can play with them. They have shape contours that consist from quadratic bezier curves and lines. I want to output triangles for such shapes so I can visualize them for the user. Traditionally I might use libfreetype or scan-rasterise this kind of contours. But I want to produce extruded 3D meshes from the fonts and make other distortions with them. So, how to polygonise shapes consisting from quadratic bezier curves and lines? There's many contours that form the shape together. Some contours are additive and others are subtractive. The contours are never open. They form a loop. (Actually, I get only contour vertices from ttf glyphs, those vertices define whether they are part of the curve or not. Even though it is easy to decompose these into bezier curves and lines, knowing the data is represented this way may be helpful for polygonizing the contours to triangles)

  • Python recursive program

    - by mathboy
    I'm relatively newcomer on programming as I'm educated a mathematician and have no experience on Python. I would like to know how to solve this problem in Python which appeared as I was studying one maths problem on my own: Program asks a positive integer m. If m is of the form 2^n-1 it returns T(m)=n*2^{n-1}. Otherwise it writes m to the form 2^n+x, where -1 < x < 2^n, and returns T(m)=T(2^n-1)+x+1+T(x). Finally it outputs the answer.

  • asp.net: moving from session variables to cookies

    - by P a u l
    My forms are losing session variables on shared hosting very quickly (webhost4life), and I think I want to replace them with cookies. Does the following look reasonable for tracking an ID from form to form: if(Request.Cookies["currentForm"] == null) return; projectID = new Guid(Request.Cookies["currentForm"]["selectedProjectID"]); Response.Cookies["currentForm"]["selectedProjectID"] = Request.Cookies["currentForm"]["selectedProjectID"]; Note that I am setting the Response cookie in all the forms after I read the Request cookie. Is this necessary? Do the Request cookies copy to the Response automatically? I'm setting no properties on the cookies and create them this way: Response.Cookies["currentForm"]["selectedProjectID"] = someGuid.ToString(); The intention is that these are temporary header cookies, not persisted on the client any longer than the browser session. I ask this since I don't often write websites.

  • What to do with lookup entities selected from drop down select ? How to send them to the service lay

    - by arrages
    I am developing a spring mvc based application. I have a simple pojo form object, the problem is that many properties will be taked from drop down lists that are populated from lookup entities, so I return the entity ID to the form object. public NewCarRequestForm { private makeId; // this are selected from a drop down. private modelId; } Should I just send this lookup entity ID to the service layer? or should I validated that this ID is correct (Somebody can send any random ID through the request) before and how? Now there is a problem if I want to validated something based on some property of the lookup entity. Do I perform a database lookup of the entity just to perform the validation? thanks.

  • can we do getwriter and forward in a single servlet

    - by karanits
    Lets say my form called a servlet. I would do some processing in it. In the servlet i want to print something on the page. for that i used PrintWriter out=response.getWriter(); out.println("some text here"); then further in the servlet i did some more form processing which works fine and after that i want the servlet to be forwarded to a jsp page. For this i used RequestDispatcher rd = request.getRequestDispatcher("/somepage.jsp"); rd.forward(request, response); the problem comes here. the text some text here gets printed, but the servlet doesn't forward request to the jsp page, as if the code doesn't run.

  • ExtJS panel does not render properly unless I open Firebug - WTF?

    - by Huuuze
    I have the following ExtJS Panel embedded in another Panel, which then resides in a TabPanel and the TabPanel is in a FormPanel. With that being said, these start/end date fields are initially displayed in very small cells -- the cells are so small that I see horizontal scroll bars. Now here's the weird part: if I open Firebug, everything pops into place. Does anyone know what's going on? Why isn't it rendering properly in the first place and why does Firebug cause everything to work properly simply by opening Firebug? var dateFields = new Ext.Panel({ id: 'dateFields', labelAlign: 'bottom', border: false, items: [{ layout: 'column', defaults: { columnWidth: 0.5 }, items: [{ layout: 'form', border: false, items: [{ xtype: 'datefield', name: 'start_date', fieldLabel: 'Start Date' }] }, { layout: 'form', border: false, items: [{ xtype: 'datefield', name: 'end_date', fieldLabel: 'End Date' }] }] }] });

  • How to send complete POST to Model in Code Igniter

    - by Constant M
    Hi there, What would be the best way to send a complete post to a model in Code Igniter? Methods I know are as follow: Name form elements as array, eg. <input type="text" name="contact[name]"> <input type="text" name="contact[surname]"> and then use: $this->Model_name->add_contact($this->input->post('contact')); The other would be to add each element to an array and then send it to the model as such: <input type="text" name="name"> <input type="text" name="surname"> and $contact_array = array('name' => $this->input->post('name'), 'surname' => $this->input->post('surname')); $this->Model_name->add_contact($this->input->post('contact')); Which one of these would be best practice, and is there a way to directly send a whole POST to a model (or a whole form maybe?)

  • Improving WPF memory usage

    - by Krishna
    Hello developers Is there any way you can store the UI state to disk when a WPF form has been minimised. I have a complex GUI with few Tab Controls and it consumes quite a bit of memory which is kept allocated when the application is not active. I was hoping one of you may have got this working along the lines (or similar) Application Active User does work, plays with UI - enters some information in the text boxes and moves around the tabs User minimises the form to work with other applications On Minimise, Save the current state to the disk and dispose the root tabcontrol On Activiate, build the root tabcontrol from the disk and add to the controls collection Before I divein to do this, I thought it will help me if I ask this question here. Please let me know your thoughts

  • Cakephp: Extend search capability to hasMany Relationship

    - by Chris
    I have two models: Car hasMany Passengers Passenger belongsTo Car I want to implement a search using Cake Search. The user should input a number and the searchengine should return all cars that have less than this number passengers. In my search form: echo $form->input('passengers', array('label' => 'Passengers', 'div' => false)); In my Car model: public $filterArgs = array( array('name' => 'passengers', 'type' => 'int'), ); In the controller: public $presetVars = array( array('field' => 'passengers', 'type' => 'int') } I thought of adding a function to the model that returns the number of passengers: function countPassengers(){ return(count($this->Car->Passenger)); //Not sure if this works } And how to I implement this search criteria?: return all Cars where countPassengers()<passenger

  • Storing PDFs in MS Access Database using Forms

    - by Matthew Jones
    I need to store PDF files in an Access database on a shared drive using a form. I figured out how to do this in tables (using the OLE Object field, then just drag-and-drop) but I would like to do this on a Form that has a Save button. Clicking the save button would store the file (not just a link) in the database. Any ideas on how to do this? EDIT: I am using Access 2003, and the DB will be stored on a share drive, so I'm not sure linking to the files will solve the problem.

    - by ThatMacLad
    I've created a form to update my websites homepage with content but I wanted to know how I could set it up so that a posts title links to a specific post ID. I'd also like to add a Read More link that directs anybody reading the blog to the correct post. Here is my PHP code: <html> <head> <title>Blog Name</title> </head> <body> <?php mysql_connect ('localhost', 'root', 'root') ; mysql_select_db ('tmlblog'); $sql = "SELECT * FROM php_blog ORDER BY timestamp DESC LIMIT 5"; $result = mysql_query($sql) or print ("Can't select entries from table php_blog.<br />" . $sql .

I really appreciate any input!

  • Doing a lot of input validation in VB.NET

    - by Andy
    I have a form set up where users can enter their booking for a room at my college. I want to validate the user input to avoid SQL injection (my program uses a MS Access database) and also stop numbers and synbols in their name, etc. I can do the validation fine, but there is to be a lot of validation and then methods executed only if all validation tests come back as true. I did have something like this: If txtName.Text = "" Then frmBookErr.SetError(txtName, "Name field cannot be left blank.") fail = 1 Else frmBookErr.SetError(txtName, "") fail = 0 End If And then check the fail variable, but it obviously gets overridden later in the form if one of the validation tests come back as true. Can anyone provide some input into this? Thanks.

  • Django Forms: TimeField Validation

    - by Tom
    I feel like I'm missing something obvious here. I have a Django form with a TimeField on it. I want to be able to allow times like "10:30AM", but I cannot get it to accept that input format or to use the "%P" format (which has a note attached saying it's a "Proprietary extension", but doesn't say where it comes from). Here's the gist of my form code: calendar_widget = forms.widgets.DateInput(attrs={'class': 'date-pick'}, format='%m/%d/%Y') time_widget = forms.widgets.TimeInput(attrs={'class': 'time-pick'}) valid_time_formats = ['%P', '%H:%M%A', '%H:%M %A', '%H:%M%a', '%H:%M %a'] class EventForm(forms.ModelForm): start_date = forms.DateField(widget=calendar_widget) start_time = forms.TimeField(required=False, widget=time_widget, help_text='ex: 10:30AM', input_formats=valid_time_formats) end_date = forms.DateField(required=False, widget=calendar_widget) end_time = forms.TimeField(required=False, widget=time_widget, help_text='ex: 10:30AM', input_formats=valid_time_formats) description = forms.CharField(widget=forms.Textarea) Any time I submit "10:30AM", I get a validation error. The underlying model has two fields, event_start and event_end, no time fields, so I don't think the problem is in there. What stupid thing am I missing?

  • What is the best way to avoid SpamCop trigger a ASP.NET web page?

    - by ncakmak
    Good Days, I have recently developed a web application in ASP.NET for a marketer that he has been sending emails to his potential customers to fill out a web form existing in this ASP.NET application. Recently, he received an email from his hosting company saying that they will suspend his account because his emails were triggered by SpamCop. He basically put a link to that web form in the email messages. What would be the best way to handle this situation? Is there a way to avoid this? Thanks, Niyazi

  • Page not redirecting properly(php)

    - by user225269
    I want to do the login page this way so that I won't be having trouble posting the username in the userpage. But everytime I try to access login.php. I get an error in firefox, that the page is not redirecting properly. What do I do? This works when I separate them into two. Into something like, login.php and verifylogin.php as the form action.

  • Help with PHP and associative arrays

    - by errata
    Hello. I have to do a simple calculator in php based on user's input and choice from select field, something like this: <?php $a = $_GET['a']; $b = $_GET['b']; $array = array( "option1" => 0.1, "option2" => 0.15, "option3" => 0.3, "option4" => 3, "option5" => 3, "option6" => 16, "option7" => 16, "option8" => 16 ); echo "<form action='calc.php' method='get'>"; echo "<input type='text' name='a' value='".$a."'> of "; echo "<select name='b'>"; foreach ($array as $k => $v) { echo "<option value='".$v."'>".$k."</option>"; } echo "</select> "; echo "<input type='submit' value='='> "; $total_volume = $a * $b; echo $total_volume; echo "</form>"; ?> Well, for now everything works fine, but the idea is that after user submits form, the page reloads with sent amount in input field and selected option which user actually selected... First thing is easy: I just put value="a" in my input field, but I'm not sure how to make a selected option in <select> field??? I started with this: foreach ($array as $k => $v) { echo "<option value='".$v."'"; if ($b == $v) { echo " selected "; } echo ">".$k."</option>"; } ...but this is obviously not working as expected... Please help me with this easy one :) Thanks!

  • iphone detailtext in UITableView question

    So, I am able to create an array that populates the fields of the Table, but am having troubles creating the subtext that appears below the main fields. I currently have: - (void)viewDidLoad { [super viewDidLoad]; listOfForms = [[NSMutableArray alloc] init]; [listOfForms addObject:@"First Form"]; } and then: NSString *cellValue = [listOfDAForms objectAtIndex:indexPath.row]; cell.textLabel.text = cellValue; in the cellForRowAtIndexPath portion. Why can't I add: listOfNames = [[NSMutableArray alloc] init]; [listOfNames addObject:@"Named Form"]; and NSString *cellSubscript = [listOfNames objectAtIndex:indexPath.row]; cell.detailTextLabel.text = cellSubscript; in order to make the little subview work? What am I doing wrong?

  • Mobile web development - how to?

    - by Adam Kiss
    Hello, I would like to start developing mobile-friendly versions of websites for my clients, however, I am baffled with options and google search wasn't very helpful - there is so many options and opinions, I've been reading for few days now and still have no idea how to start. What's your opinion/experience about/with it? My main points: mobile devices supported (in order of relevance): iPhone 3G, iPhone 2G, Blackberry, Droid powered mobiles, other phone friendly numbers, phone friendly emails contact/register form working on each (or the most possible) devices listed jQTouch seems superb (simple, quick, working), I'm not sure about it on blackberry/droid and I don't want to create 6 web versions for each mobile device - Makes even less sense if you consider, that I'm starting with small web (6-10 pages, 1 contact form, 3 register forms) to play with. Thank you

  • Problems with starting windows service on windows xp SP3

    - by Michiel Peeters
    I'm currently facing a problem which I can not resolve and I really don't know what to do anymore. When I'm trying to start the service I receive the message: "The service is started but again also stopped, this because that some of the services will stop if they have nothing to do, for example the performance logs and the alerts service". I've looked into the Windows Logs but nothing is written there which could describe why my service is all the time stopping. I've also tried to fire the windows service via the command prompt which gives me the message: "The service is not started, but the service didn't return any faults.". I've tried to remove all keys which references to my service, which didn't resolve the issue. I've searched on google (maybe not good enough) to find an answer but I didn't found any. I did found some websites which describes what I could do, but all of these suggestions didn't work. This is kinda ** because I do not know where to look. I do not have any error message, i do not have any id which i can use to search on. I really don't know where to start and I hope you guys can help me on this one. Detailed explanation about the windows service OS: Windows XP SP3 .Net Framework: .Net 4.0 Client Profile Language: C# Development environment: Visual Studio 2010 Professional (but Visual Studio 2012 RC is installed) Communications: WCF (Named Pipes), WCF (BasicHTTPBinding) Named Pipes: I have chosen for this solution because I wanted to communicate from a windows service to a windows form application. It worked now for quite some time but suddenly my windows service shuts it self down and I couldn't restart it anymore. There are two named pipes services implemented: An event service which will send any notification to the windows form application and an management service which gives my windows form application the possibility to maintain my windows service. BasicHTTPBinding: The basic http binding makes the connection to a central server. This connection is then used for streaming information from the client to the server. I do not know which additional information you will need, but if you guys need something then I'll try to give it as detailed as possible. Thank you in advance.
