  • Modify Django Forms

    - by Ninefingers
    Hi All, I've recently been developing on the django platform and have stumbled upon Django Forms (forms.Form/forms.ModelForm) as ways of creating <form> html. Now, this is brilliant for quick stuff but what I'm trying to do is a little bit more complicated. Consider a DateField - my current form has fields for day, month and year and constructs a python date object from that. However, a django form creates a single textbox in which the correct format (say 2010-06-15) must be entered. As another example, for large fields I need to replace <input> with <textarea>. I'd like to take advantage of Django's forms for simple validation but I need something simpler for my users. So my question is: can I intercept the rendering of one of these objects to write out the html as I like? If so, do I have to do all the writing myself or can I only do those objects I wish to re-write? Thanks in advance.

  • Postback event not firing on FIRST button click..

    - by ClarkeyBoy
    Hi, I have a form which accepts two arguments. The first one is mode - this is either view, new or edit. If it is new then the second argument is type - this is either range, collection or design. When set to new, and the type is valid, a new instance of that type is created and the data from the form is added to it. The item (range, collection or design) then validates the data. If any of the data is invalid then it throws an error, and this error is displayed at the top of the form telling the user why it is invalid. A variable, _Databind, is set to false so that it does not change the data input by the user (in the form fields). The button used to submit the button is called btnSave, and is created in the html source. The click event is wired up in the form Protected Sub Blah(sender, e) Handles btnSave.Click. Strangely, whenever I edit an item that already exists the form submits fine the first time - the click event is fired. However when in "new" mode I have to click the button twice to fire the event. It also blanks all the form fields out on first click. I have even put a Response.Write("Hello World") line at the start of the click event - this is not being output on first click when adding a new item either. It is on first load when the mode is set to edit however. Does anyone have any ideas as to what is causing it to behave this way? Thanks in advance for any help. Regards, Richard

  • IIS7 Web.Config Custom Errors

    - by Michael
    Using GoDaddy to host my site (I know that's my first problem)! :-) Trying to setup customer error messages for my site. GoDaddy allows you to setup a 404 in their control panel, but I can't override this, or setup any additional error redirects, specifically a 500-server error. Here is my web.config file: <configuration> <system.webServer> <rewrite> <rules> <rule name="Redirect to WWW" stopProcessing="true"> <match url=".*" /> <conditions> <add input="{HTTP_HOST}" pattern="^mysite.com$" /> </conditions> <action type="Redirect" url="http://www.mysite.com/{R:0}" redirectType="Permanent" /> </rule> </rules> </rewrite> </system.webServer> <system.web> <customErrors mode="On" defaultRedirect="http://www.mysite.com/oops.php"> <error statusCode="404" redirect="http://www.mysite.com/oops.php?error=404" /> <error statusCode="500" redirect="http://www.mysite.com/oops.php?error=500" /> </customErrors> </system.web> </configuration>

  • Paperclip wont save image in rails app

    - by Micke
    Hello stackoverflow. I am trying to use Paperclip with my rails app to add an avatar to a user but it wont save my image when creating the user. This is what the model looks like: class User < ActiveRecord::Base has_attached_file :avatar And the registerform in haml: - form_for :user, @user, :url => { :action => "signup" }, :html => { :multipart => true } do |f| ... ... %li %div{:class => "header"} Profilepicture %div{:class => "input"} = f.file_field :avatar And when i look in the log this is what is being passet to the "signup" action: Parameters: {"commit"=>"Save", "action"=>"signup", "controller"=>"user/register", "user"=>{"name"=>"Micke Lisinge", "birthmonth"=>"07", "password_confirmation"=>"[FILTERED]", "nickname"=>"lisinge", "avatar"=>#<File:/tmp/RackMultipart20100426-3076-1x04oxy-0>, "gen"=>"m", "birthday"=>"23", "password"=>"[FILTERED]", "birthyear"=>"1992", "email"=>"[email protected]"}} [paperclip] Saving attachments. Paperclip says it is saving the template but when i look in the public folder in my app it has created a system but the system folder is empty. So it seems like it isnt saving the picture to the folder. It gets handled by the form and saved in my /tmp folder. Maybe you guys have any tips or know what this problem might be? Thanks in advance, Micke.

  • Code Golf: Tic Tac Toe

    - by Aistina
    Post your shortest code, by character count, to check if a player has won, and if so, which. Assume you have an integer array in a variable b (board), which holds the Tic Tac Toe board, and the moves of the players where: 0 = nothing set 1 = player 1 (X) 2 = player 2 (O) So, given the array b = [ 1, 2, 1, 0, 1, 2, 1, 0, 2 ] would represent the board X|O|X -+-+- |X|O -+-+- X| |O For that situation, your code should output 1 to indicate player 1 has won. If no-one has won you can output 0 or false. My own (Ruby) solution will be up soon. Edit: Sorry, forgot to mark it as community wiki. You can assume the input is well formed and does not have to be error checked. Update: Please post your solution in the form of a function. Most people have done this already, but some haven't, which isn't entirely fair. The board is supplied to your function as the parameter. The result should be returned by the function. The function can have a name of your choosing.

  • Problem with reCaptcha and .NET

    - by vtortola
    Hi, I get this error with reCaptcha: 'Input error: response: Required field must not be blank challenge: Required field must not be blank privatekey: Required field must not be blank' I'm sending the data via POST, so I don't understand what is going on. This is the code I use: public static Boolean Check(String challenge, String response) { try { String privatekey = "7LeAbLoSAAAABJBn05uo6sZoFNoFnK2XKyF3dRXL"; String remoteip = HttpContext.Current.Request.UserHostAddress; WebRequest req = WebRequest.Create("http://api-verify.recaptcha.net/verify"); req.Method = "POST"; using (StreamWriter sw = new StreamWriter(req.GetRequestStream())) { sw.Write("privatekey={0}&remoteip={1}&challenge={2}&response={3}", privatekey, remoteip, challenge, response); sw.Flush(); } String resultString = String.Empty; String errorString = String.Empty; using (StreamReader sr = new StreamReader(req.GetResponse().GetResponseStream())) { resultString = sr.ReadLine(); errorString = sr.ReadLine(); } Boolean b; return Boolean.TryParse(resultString, out b) && b; } catch (Exception) { return false; } } (Of course that'is not the correct private key :P) I have no idea what the problem is about, I think I'm sending the data correctly, but that error says that apparently I'm not sending anything. What could be the problem? Cheers.

  • Problem with extended ASCII characters in web page/master page

    - by Oyvind Brathen
    I have some localization problems in my webpage. There are basically two problems (that I suspect have a different sulution, but they are conseptually linked) First problem is this: I have a website that is using a master page. All text from the page is fine, but all text that comes from the master page file, get scrambled norwegian characters. For example Ø shows up as Ø. It seems that all characthers in the extended ASCII table gets scrambled this way. Afterwards, if I open the master page in Notepad the Ø looks normal, but if I remove the Ø and write a new Ø manually, then save the file from Notepad, and then open the website in the browser, it looks fine and the Ø is shown properly. So it seems that Visual Studio saves the characters wrongly in the master file, but correct for the aspx file. Any clue here? The second issue is norwegian characters coming from jQuery. All of these characters get's replaced by a questionmark with a black box around it. Here, modifying the js file in Notepad does not help, and it still display scrambled in the browser. Any input here would be appreciated.

  • WTL Child window event handling

    - by Rushi
    I am developing window application in that I am having 2 child windows on left and right side. I want to handle input events for both windows separately. How to achieve it?

  • Ruby - Immutable Objects

    - by Chris Bunch
    I've got a highly multithreaded app written in Ruby that shares a few instance variables. Writes to these variables are rare (1%) while reads are very common (99%). What is the best way (either in your opinion or in the idiomatic Ruby fashion) to ensure that these threads always see the most up-to-date values involved? Here's some ideas so far that I had (although I'd like your input before I overhaul this): Have a lock that most be used before reading or writing any of these variables (from Java Concurrency in Practice). The downside of this is that it puts a lot of synchronize blocks in my code and I don't see an easy way to avoid it. Use Ruby's freeze method (see here), although it looks equally cumbersome and doesn't give me any of the synchronization benefits that the first option gives. These options both seem pretty similar but hopefully anyone out there will have a better idea (or can argue well for one of these ideas). I'd also be fine with making the objects immutable so they aren't corrupted or altered in the middle of an operation, but I don't know Ruby well enough to make the call on my own and this question seems to argue that objects are highly mutable.

  • What is the most platform- and Python-version-independent way to make a fast loop for use in Python?

    - by Statto
    I'm writing a scientific application in Python with a very processor-intensive loop at its core. I would like to optimise this as far as possible, at minimum inconvenience to end users, who will probably use it as an uncompiled collection of Python scripts, and will be using Windows, Mac, and (mainly Ubuntu) Linux. It is currently written in Python with a dash of NumPy, and I've included the code below. Is there a solution which would be reasonably fast which would not require compilation? This would seem to be the easiest way to maintain platform-independence. If using something like Pyrex, which does require compilation, is there an easy way to bundle many modules and have Python choose between them depending on detected OS and Python version? Is there an easy way to build the collection of modules without needing access to every system with every version of Python? Does one method lend itself particularly to multi-processor optimisation? (If you're interested, the loop is to calculate the magnetic field at a given point inside a crystal by adding together the contributions of a large number of nearby magnetic ions, treated as tiny bar magnets. Basically, a massive sum of these.) # calculate_dipole # ------------------------- # calculate_dipole works out the dipole field at a given point within the crystal unit cell # --- # INPUT # mu = position at which to calculate the dipole field # r_i = array of atomic positions # mom_i = corresponding array of magnetic moments # --- # OUTPUT # B = the B-field at this point def calculate_dipole(mu, r_i, mom_i): relative = mu - r_i r_unit = unit_vectors(relative) #4pi / mu0 (at the front of the dipole eqn) A = 1e-7 #initalise dipole field B = zeros(3,float) for i in range(len(relative)): #work out the dipole field and add it to the estimate so far B += A*(3*dot(mom_i[i],r_unit[i])*r_unit[i] - mom_i[i]) / sqrt(dot(relative[i],relative[i]))**3 return B

  • Rails Autocompletion Issue - Rails 1.2.3 to 2.3.5

    - by Grant Sayer
    I have an issue with rails Autocompletion from some code that i've inherited from an old Rails 1.2.3 project that I'm porting to Rails 2.3.5. The issue revolves around javascript execution within the auto_complete helper :after_update_element. The scenario is: A user is presented with a popup form with a number of fields. In the first field as they enter text the auto_complete AJAX call occurs, returning a result, plus a series of other HTML data wrapped in <divs> so that the after_update_element call can iterate over the other data and fill in the remaining fields. The issue lies with the extraction of the other fields which works on IE, fails on Firefox. Here is the code: <%= text_field_with_auto_complete :item, :product_code, {:value => ""}, {:size => 40, :class => "input-text", :tabindex => 6, :select => 'code', :with => "element.name + '=' + escape(element.value) + '&supplier_id=' + $('item_supplier_id').value", :after_update_element => "function (ele, value) { $('item_supplier_id').value = Utilities.extract_value(value, 'supplier_id'); $('item_supplied_size').value = Utilities.extract_value(value, 'size')}"}%> Now the function Utilities is designed to grab the fields from the string of values and looks like: // // Extract a particular set of data from the autocomplete actions // Utilities.extract_value = function (value, className) { var result; var elements = document.getElementsByClassName(className, value); if (elements && elements.length == 1) { result = elements[0].innerHTML.unescapeHTML(); } return result; }; In Firefox the value of result is undefined

  • Create Jinja2 macros that put content in separate places

    - by Brian M. Hunt
    I want to create a table of contents and endnotes in a Jinja2 template. How can one accomplish these tasks? For example, I want to have a template as follows: {% block toc %} {# ... the ToC goes here ... #} {% endblock %} {% include "some other file with content.jnj" %} {% block endnotes %} {# ... the endnotes go here ... #} {% endblock %} Where the some other file with content.jnj has content like this: {% section "One" %} Title information for Section One (may be quite long); goes in Table of Contents ... Content of section One {% section "Two" %} Title information of Section Two (also may be quite long) <a href="#" id="en1">EndNote 1</a> <script type="text/javsacript">...(may be reasonably long) </script> {# ... Everything up to here is included in the EndNote #} Where I say "may be quite/reasonably long" I mean to say that it can't reasonably be put into quotes as an argument to a macro or global function. I'm wondering if there's a pattern for this that may accommodate this, within the framework of Jinja2. My initial thought is to create an extension, so that one can have a block for sections and end-notes, like-so: {% section "One" %} Title information goes here. {% endsection %} {% endnote "one" %} <a href="#">...</a> <script> ... </script> {% endendnote %} Then have global functions (that pass in the Jinja2 Environment): {{ table_of_contents() }} {% include ... %} {{ endnotes() }} However, while this will work for endnotes, I'd presume it requires a second pass by something for the table of contents. Thank you for reading. I'd be much obliged for your thoughts and input. Brian

  • .NET Test Harness what should it have

    - by Conor
    Hi Folks, We have a software house developing code for us on a project, .NET Web Service (WCF) and we are also paying for a test harness to be built as a separate billable task on a daily rate. I have just joined the company and am reviewing what we are getting from the software house and wanted to know what you guys in industry thought about it? Basically what we got was a WinForm that called the w/s that had an input area (Web Service Request) to drop our XML a Submit button along with a response area for the result of the Web Response and that's it... Our internal BA has created all the xml request documents so there was no logic put into the harness around this. Looking on the Net for a definition of a Test Harness I got this: http://en.wikipedia.org/wiki/Test_harness It states it should have these 3 below things: Automate the testing process. Execute test suites of test cases. Generate associated test reports. Clearly we have got none of this apart from a partial "Automate the testing process" via a WinForm. OK, from my development background I would expect someone to Produce a WinForm as a test harness 5 years ago and really should be using some sort of Tooling around this, I explicitly told the Software House I expected some sort of tooling (NUnit,NBUnit, SOAPIU) so we could create a regression test pack for future use. [Didn’t get it but I asked for this after the requirements were signed off as I wasn’t employed then :)] Would someone be able to clarify with me if my requirement for this is over realistic, I know if I did this, I would use NUnit and TDD and then reuse the test harness as a regression test pack in future? I am interested to see what the community thought. Cheers

  • Difference dynamic static 2d array c++

    - by snorlaks
    Hello, Im using opensource library called wxFreeChart to draw some XY charts. In example there is code which uses static array as a serie : double data1[][2] = { { 10, 20, }, { 13, 16, }, { 7, 30, }, { 15, 34, }, { 25, 4, }, }; dataset->AddSerie((double *) data1, WXSIZEOF(dynamicArray)); WXSIZEOF ismacro defined like: sizeof(array)/sizeof(array[0]) In this case everything works great but in my program Im using dynamic arrays (according to users input). I made a test and wrotecode like below: double **dynamicArray = NULL; dynamicArray = new double *[5] ; for( int i = 0 ; i < 5 ; i++ ) dynamicArray[i] = new double[2]; dynamicArray [0][0] = 10; dynamicArray [0][1] = 20; dynamicArray [1][0] = 13; dynamicArray [1][1] = 16; dynamicArray [2][0] = 7; dynamicArray [2][1] = 30; dynamicArray [3][0] = 15; dynamicArray [3][1] = 34; dynamicArray [4][0] = 25; dynamicArray [4][1] = 4; dataset->AddSerie((double *) *dynamicArray, WXSIZEOF(dynamicArray)); But it doesnt work correctly. I mean point arent drawn. I wonder if there is any possibility that I can "cheat" that method and give it dynamic array in way it understands it and will read data from correct place thanks for help

  • Format date from SQLCE to display in DataGridView

    - by Ruben Trancoso
    hi folks, I have a DataGridView bound to a table from a .sdf database through a BindSource. The date column display dates like "d/M/yyyy HH:mm:ss". e.: "27/2/1971 00:00:00". I want to make it display just "27/02/1971" in its place. I tried to apply DataGridViewCellStyle {format=dd/MM/yyyy} but nothing happens, event with other pre-built formats. On the the other side, there's a Form with a MasketTextBox with a "dd/MM/yyyy" mask to its input that is bound to the same column and uses a Parse and a Format event handler before display and send it to the db. Binding dataNascimentoBinding = new Binding("Text", this.source, "Nascimento", true); dataNascimentoBinding.Format += new ConvertEventHandler(Util.formatDateConvertEventHandler); dataNascimentoBinding.Parse += new ConvertEventHandler(Util.parseDateConvertEventHandler); this.dataNascimentoTxt.DataBindings.Add(dataNascimentoBinding); public static string convertDateString2DateString(string dateString, string inputFormat, string outputFormat ) { DateTime date = DateTime.ParseExact(dateString, inputFormat, DateTimeFormatInfo.InvariantInfo); return String.Format("{0:" + outputFormat + "}", date); } public static void formatDateConvertEventHandler(object sender, ConvertEventArgs e) { if (e.DesiredType != typeof(string)) return; if (e.Value.GetType() != typeof(string)) return; String dateString = (string)e.Value; e.Value = convertDateString2DateString(dateString, "d/M/yyyy HH:mm:ss", "dd/MM/yyyy"); } public static void parseDateConvertEventHandler(object sender, ConvertEventArgs e) { if (e.DesiredType != typeof(string)) return; if (e.Value.GetType() != typeof(string)) return; string value = (string)e.Value; try { e.Value = DateTime.ParseExact(value, "dd/MM/yyyy", DateTimeFormatInfo.InvariantInfo); } catch { return; } } Like you can see by the code it was expexted that Date coming from SQL would be a DateTime value as is its column, but my eventHandler is receiving a string instead. Likewise, the result date for parse should be a datetime but its a string also. I'm puzzled dealing with this datetime column.

  • css positioning

    - by bsreekanth
    Hello, I have uploaded a part of my screen below (link: http://yfrog.com/0d30127380p) It is part of a forum, so there are elements above and below it. The "Response Req.. Date" has a label, a date picker, and two drop down select control for time. I tried setting the width of the datepicker element, and a right margin so that the time selectors would position next to it. But it always sit below it. I'm not good in css positioning, so any suggestion would be highly appreciated. <div class="wrapper "> <label for="responseRequiredDate"> Response Required Date <span class="indicator">*</span> </label> <input type="hidden" name="responseRequiredDate" value="struct" /><div class="datetimepicker"> <div class="datePicker"> </div> <script> ...</script> <div class="timepicker"><select .... </div> </div> the date picker insert a script tag, would that cause a problem. probably not.

  • Posting xml from classic asp to asp.net

    - by Chris Dunaway
    I apologize if this has been asked before. I searched and didn't find anything that matched my situation. Also bear in mind I am fairly new to asp/asp.net development. My current project is a relatively simple e-commerce site. The customer will connect to the site, select products, input shipping and billing information, payment information (credit card) and submit the order. The project is being split into two parts: The store front which includes displaying the items and taking the customer's shipping and billing information and the payment site which will collect the customers credit card, compute tax, and save the order into the company's system. The reason that the site was split up, was that our side (payment side) already has facilities for credit card handling and tax computation. There may also be some regulatory issues that the store front side does not want to deal with (which we already do). I'm working on the payment portion of the app and I am using asp.net. The store front side is being written in classic asp (not my decision). Each part will be hosted on different servers. The problem I am having is transferring the contents of the "shopping cart" to our app so that we can collect the cc info and submit the order. We had thought that the classic asp could somehow post an xml fragment which contains the billing/shipping info and the items selected. Our side would display a summary of the order, securely collect the credit card info, and submit the order to our system. But I have been unable to post or send the xml from a classic asp on one server, to our asp.net application on another. It all works just fine when I test on the same server. How can I post (or otherwise transfer) the shopping cart data from classic asp to asp.net across server boundaries and transfer control to the asp.net application? As I said, I am new to web development, so this is proving quite a challenge for me. Thanks

  • How to include multiple tables programmaticaly into a Sweave document using R

Any ideas what I'm doing wrong ?

  • jquery newbie: combine validate with hidding submit button.

    - by Jeffb
    I'm new a jQuery. I have gotten validate to work with my form (MVC 1.0 / C#) with this: <script type="text/javascript"> if (document.forms.length > 0) { document.forms[0].id = "PageForm"; document.forms[0].name = "PageForm"; } $(document).ready(function() { $("#PageForm").validate({ rules: { SigP: { required: true } }, messages: { SigP: "<font color='red'><b>A Sig Value is required. </b></font>" } }); }); </script> I also want to hide the Submit button to prevent twitchy mouse syndrome from causing duplicate entry before the controller completes and redirects (I'm using an GPR pattern). The following works for this purpose: <script type="text/javascript"> // // prevent double-click on submit // jQuery('input[type=submit]').click(function() { if (jQuery.data(this, 'clicked')) { return false; } else { jQuery.data(this, 'clicked', true); return true; } }); </script> However, I can't get the two to work together. Specifically, if validate fails after the Submit button is clicked (which happens given how the form works), then I can't get the form submitted again unless I do a browser refresh that resets the 'clicked' property. How can I rewrite the second method above to not set the clicked property unless the form validates? Thx.

  • Use Java exceptions internally for REST API user errors?

    - by user303396
    We have a REST API that works great. We're refactoring and deciding how to internally handle errors by the users of our API. For example the user needs to specify the "movie" url parameter which should take the value of "1984", "Crash", or "Avatar". First we check to see if it has a valid value. What would be the best approach if the movie parameter is invalid? return null from one of the internal methods and check for the null in the main API call method throw an exception from the internal method and catch exceptions in the main API method I think it would make our code more readable and elegant to use exceptions. However, we're reluctant because we'd be potentially throwing many exceptions because of user API input errors, our code could be perfect. This doesn't seem to be the proper use of exceptions. If there are heavy performance penalties with exceptions, which would make sense with stack traces needing to be collected, etc., then we're unnecessarily spending resources when all we need to do is tell the user the parameter is wrong. These are REST API methods, so we're not propogating the exceptions to the users of the API, nor would we want to even if possible. So what's the best practice here? Use ugly nulls or use java's exception mechanism?

  • FasterCSV Parsing issue?

    - by Schroedinger
    G'day guys, I'm currently using fastercsv to construct ActiveRecord elements and I can't for the life of me see this bug (tired), but for some reason when it creates, if in the rake file i output the column I want to save as the element value, it puts out correctly, as either a Trade or a Quote but when I try to save it into the activerecord, it won't work. FasterCSV.foreach("input.csv", :headers => true) do |row| d = DateTime.parse(row[1]+" "+row[2]) offset = Rational(row[3].to_i,24) o = d.new_offset(offset) t = Trade.create( :name => row[0], :type => row[4], :time => o, :price => row[6].to_f, :volume => row[7].to_i, :bidprice => row[10].to_f, :bidsize => row[11].to_i, :askprice => row[14].to_f, :asksize => row[15].to_i ) end Ideas? Name and Type are both strings, every other value works except for type. Have I missed something really simple?

  • Django Upload form to S3 img and form validation

    - by citadelgrad
    I'm fairly new to both Django and Python. This is my first time using forms and upload files with django. I can get the uploads and saves to the database to work fine but it fails to valid email or check if the users selected a file to upload. I've spent a lot of time reading documentation trying to figure this out. Thanks! views.py def submit_photo(request): if request.method == 'POST': def store_in_s3(filename, content): conn = S3Connection(AWS_ACCESS_KEY_ID, AWS_SECRET_ACCESS_KEY) bucket = conn.create_bucket(AWS_STORAGE_BUCKET_NAME) mime = mimetypes.guess_type(filename)[0] k = Key(bucket) k.key = filename k.set_metadata("Content-Type", mime) k.set_contents_from_file(content) k.set_acl('public-read') if imghdr.what(request.FILES['image_url']): qw = request.FILES['image_url'] filename = qw.name image = filename content = qw.file url = "http://bpd-public.s3.amazonaws.com/" + image data = {image_url : url, user_email : request.POST['user_email'], user_twittername : request.POST['user_twittername'], user_website : request.POST['user_website'], user_desc : request.POST['user_desc']} s = BeerPhotos(data) if s.is_valid(): #import pdb; pdb.set_trace() s.save() store_in_s3(filename, content) return HttpResponseRedirect(reverse('photos.views.thanks')) return s.errors else: return errors else: form = BeerPhotoForm() return render_to_response('photos/submit_photos.html', locals(),context_instance=RequestContext(request) forms.py class BeerPhotoForm(forms.Form): image_url = forms.ImageField(widget=forms.FileInput, required=True,label='Beer',help_text='Select a image of no more than 2MB.') user_email = forms.EmailField(required=True,help_text='Please type a valid e-mail address.') user_twittername = forms.CharField() user_website = forms.URLField(max_length=128,) user_desc = forms.CharField(required=True,widget=forms.Textarea,label='Description',) template.html <div id="stylized" class="myform"> <form action="." method="post" enctype="multipart/form-data" width="450px"> <h1>Photo Submission</h1> {% for field in form %} {{ field.errors }} {{ field.label_tag }} {{ field }} {% endfor %} <label><span>Click here</span></label> <input type="submit" class="greenbutton" value="Submit your Photo" /> </form> </div>

  • delphi 2010 variant to unicode problem

    - by Crudler
    Please advise how I can achieve this. I am working in a dll in delphi 2010. This dll has a exported procedure that receives an array of variants. I want to be able to take one of these variants, and convert it into a string, but i keep getting ????? I cannot change the input variable - it HAS to be an array of variants. The host app that calls the dll cannot be changed. It is written in Delphi2006. sample dll's code is: Procedure TestArr(ArrUID : array of variant);stdcall; var i : integer; s:string; begin s:= string(String(Arruid[0])); showmessage(s); end; obviously in D2006 my dll works fine. I have tried using VartoStr - no luck. When I try test the VaType I am getting a varString Any suggestions?

    When the button in the following script gets clicked, it should load in the contents of the file "http://tanguay.info/knowsite/data.txt" and display it on the screen. What is the correct syntaxt so that the .get() function retrieves the data from the external website and puts it in #content? <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <script type="text/javascript" src="http://www.google.com/jsapi"></script> <script type="text/javascript"> google.load("jquery", "1.3.2"); google.setOnLoadCallback(function() { $('#toggleButton').click(loadDataFromExernalWebsite); }); function loadDataFromExernalWebsite() { $('#content').html('new content'); //$.get("http://tanguay.info/knowsite/data.txt", function(data) { alert(data); }, ); } </script> </head> <body> <p>Click the button to load content:</p> <p id="content"></p> <input id="toggleButton" type="button" value="load content"/> </body> </html>
