• Could someone explain gtk2hs drag and drop to me, the listDND.hs demo just isn't doing it for me?

  - by Tom Carstens

  As the title says, I just don't get DND (or rather I understand the concept and I understand the order of callbacks, I just don't understand how to setup DND for actual usage.) I'd like to say that I've done DND stuff before in C, but considering I never really got that working... So I'm trying (and mostly succeeding, save DND) to write a text editor (using gtksourceview, because it has built in code highlighting.) Reasons are below if you want them. Anyways, there's not really a good DND demo or tutorial available for gtk2hs (listDND.hs just doesn't translate well in my head.) So what I'm asking is for code that demonstrates simple DND on a window widget (for example.) Ideally, it should accept drops from other windows (such as Thunar) and print out the information in string form. I think I can take it from there... Reasons: I'm running a fairly light weight setup, dwm and a few gtk+2 programs. I really don't want to have to pull in gtk+3 to get the current gedit from the repos (Arch Linux.) Currently, I'm using geany for all of my text editing needs, however, geany is a bit heavy for editing config files. Further, geany doesn't care for my terminal of choice (st;) so I don't even get the benefit of using it as an IDE. Meaning I'd like a lightweight text editor with syntax highlighting. I could configure emacs or vim or something, but that seems to me to be more of a hack then a proper solution. Thus my project was born. It's mostly working (aside from DND, all that's left is proper multi-tab support.) Admittedly, I could probably work this out if I wrote it in C, but there isn't that much state in a text editor so Haskell's been working fine with almost no need for mutable variables.

• I need Selenium to open it's web browser in a larger resolution ( preferably maximized)

  - by user1854271

  I am using Selenium WebDriver and coding in Python I have looked all over the place and the best I could find were things written in different languages. I also tried to use the export tool on Selenium IDE but when I look at the data says that the function is not supported for export. EDIT: The reason I need the browser to open up with a larger resolution is because the web application that I am testing is supporting tablet resolution as so elements are different depending on the resolution of the browser window. This is the script I exported from the IDE with a couple of modifications. from selenium import webdriver from selenium.webdriver.common.by import By from selenium.webdriver.support.ui import Select from selenium.common.exceptions import NoSuchElementException import unittest, time, re from Funk_Lib import RS class CreatingEditingDeletingVault(unittest.TestCase): def setUp(self): self.driver = webdriver.Firefox() self.driver.implicitly_wait(30) self.base_url = "http://cimdev-qa40/" self.verificationErrors = [] def test_creating_editing_deleting_vault(self): driver = self.driver driver.get(self.base_url + "/Login?contoller=Home") driver.find_element_by_id("UserName").click() driver.find_element_by_id("UserName").clear() driver.find_element_by_id("UserName").send_keys("[email protected]") driver.find_element_by_name("Password").click() driver.find_element_by_name("Password").clear() driver.find_element_by_name("Password").send_keys("Codigo#123") driver.find_element_by_id("fat-btn").click() driver.get(self.base_url + "/Content/Vaults/") driver.find_element_by_link_text("Content").click() driver.find_element_by_link_text("Vaults").click() driver.find_element_by_css_selector("button.btn.dropdown-toggle").click() driver.find_element_by_link_text("New vault").click() driver.find_element_by_name("Name").clear() driver.find_element_by_name("Name").send_keys("Test Vault") driver.find_element_by_xpath("//button[@onclick=\"vault_action('createvault', null, $('#CreateVault [name=\\'Name\\']').val())\"]").click() driver.find_element_by_css_selector("button.btn.dropdown-toggle").click() driver.find_element_by_link_text("Rename vault").click() driver.find_element_by_name("Id").click() Select(driver.find_element_by_name("Id")).select_by_visible_text("Test Vault") driver.find_element_by_css_selector("option[value=\"2\"]").click() driver.find_element_by_name("Name").clear() driver.find_element_by_name("Name").send_keys("Test Change") driver.find_element_by_xpath("//button[@onclick=\"vault_action('renamevault', $('#RenameVault [name=\\'Id\\']').val(), $('#RenameVault [name=\\'Name\\']').val())\"]").click() driver.find_element_by_css_selector("button.btn.dropdown-toggle").click() driver.find_element_by_link_text("Delete vault").click() driver.find_element_by_name("Id").click() Select(driver.find_element_by_name("Id")).select_by_visible_text("Test Change") driver.find_element_by_css_selector("option[value=\"2\"]").click() driver.find_element_by_xpath("//button[@onclick=\"vault_action('deletevault', $('#DeleteVault [name=\\'Id\\']').val(), '')\"]").click() def is_element_present(self, how, what): try: self.driver.find_element(by=how, value=what) except NoSuchElementException, e: return False return True def tearDown(self): self.driver.quit() self.assertEqual([], self.verificationErrors) if __name__ == "__main__": unittest.main()

• AJAX UpdatePanel.Visible Property not working with Javascript

Although javascript funciton seems to be working fine in debugging, it does not hide! <%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="_Default" % <script type="text/javascript" language="javascript"> function Show() { document.getElementById("UpdatePanel1").Visible = true; } function Hide() { document.getElementById("UpdatePanel1").Visible = false; } </script> <asp:ScriptManager ID="ScriptManager1" runat="server"> </asp:ScriptManager> <asp:Button ID="btnShow" runat="server" Text="Show" OnClientClick="Show(); return false;" /> <asp:Button ID="BtnHide" runat="server" Text="Hide" OnClientClick="Hide(); return false;" /> <asp:UpdatePanel ID="UpdatePanel1" runat="server"> <ContentTemplate> <br /> <asp:TextBox ID="TextBox1" runat="server" TextMode="MultiLine"></asp:TextBox> <br /> <asp:Button ID="btnSubmit" runat="server" Text="Gönder" onclick="btnSubmit_Click" /> <br /> </ContentTemplate> </asp:UpdatePanel> </div> </form>

• CSS - How to create a table cell with a two-colour background?

  - by Chris

  Hi, I'm trying to create an HTML table cell with a two-tone background; so I have normal text on a background which is yellow on the left, and green on the right. The closest I've got so far is as follows. The background is correctly half-and-half, but the content text is displaced below it. <html> <head> <style type='text/css'> td.green { background-color: green; padding: 0px; margin: 0px; height:100%; text-align:center } div.yellow { position:relative; width: 50%; height: 100%; background-color:yellow } </style> </head> <body style="width: 100%"> <table style="width: 25%"> <tr style="padding: 0px; margin: 0px"> <td class="green"> <div class="yellow"></div> <div class="content">Hello</div> </td> </tr> </table> </body> </html> How can I fix this up?

• Exporting and reformatting data out of MS Excel

  - by Matt H

  I have a huge Excel spreadsheet containing telephone calling rates to a number of different countries. The format of the columns is: Country, RateLocality, Prefixes, Rate, Wholesale e.g. Afganistan, Default, 93;930;931;9321;9322;9323;9324;9325;9326;9327;9328;9329;9331;9332;9333;9334;9335;9336;9337;9338;9339;9341;9342;9343;9344;9345;9346;9347;9348;9349;9351;9352;9353;9354;9355;9356;9357;9358;9359;9361;9362;9363;9364;9365;9366;9367;9368;9369;9371;9372;9373;9374;9376;938;939; $ 1.023, $0.455 These rates change every so often and I need to get them into another system that can import them using CSV. The eventual format is: LD PREPEND CODE ie. 00 or 011,CountryCode,Area Code,Comment,Connect Cost,Included Seconds,Per Minute Cost,Pricelist,Increment So to convert that above line I'd have 00,"Afganistan",93,"Default",1.023,60,1.023,10 00,"Afganistan",931,"Default",1.023,60,1.023,10 ... 00,"Afganistan",939,"Default",1.023,60,1.023,10 Where 00, 60 and 10 are hard coded and merged with the other data from excel. How can I export this data into the required format given that I need to reformat it as it goes. Should I export to XML and use XSLT or some other process to massage the data into CSV? If that is the case, how do I do it simply and quickly.

• Making a button click and process using javascript with Asp.Net

  - by user944919

  I'm having two buttons and one button is hidden. Now when I click the visible button I need to do two things 1.Open Iframe. 2.Automatically make the 2nd Button(Hidden)to be clicked. When the second button is clicked I need to display the message on top of the IFrame which I have mentioned as function showStickySuccessToast() Now I am able to open IFrame but I'm unable to make the Hidden button clicked automatically.

• Where do you put your dependencies?

  - by The All Foo

  If I use the dependency injection pattern to remove dependencies they end up some where else. For example, Snippet 1, or what I call Object Maker. I mean you have to instantiate your objects somewhere...so when you move dependency out of one object, you end up putting it another one. I see that this consolidates all my dependencies into one object. Is that the point, to reduce your dependencies so that they all reside in a single ( as close to as possible ) location? Snippet 1 - Object Maker <?php class ObjectMaker { public function makeSignUp() { $DatabaseObject = new Database(); $TextObject = new Text(); $MessageObject = new Message(); $SignUpObject = new ControlSignUp(); $SignUpObject->setObjects($DatabaseObject, $TextObject, $MessageObject); return $SignUpObject; } public function makeSignIn() { $DatabaseObject = new Database(); $TextObject = new Text(); $MessageObject = new Message(); $SignInObject = new ControlSignIn(); $SignInObject->setObjects($DatabaseObject, $TextObject, $MessageObject); return $SignInObject; } public function makeTweet( $DatabaseObject = NULL, $TextObject = NULL, $MessageObject = NULL ) { if( $DatabaseObject == 'small' ) { $DatabaseObject = new Database(); } else if( $DatabaseObject == NULL ) { $DatabaseObject = new Database(); $TextObject = new Text(); $MessageObject = new Message(); } $TweetObject = new ControlTweet(); $TweetObject->setObjects($DatabaseObject, $TextObject, $MessageObject); return $TweetObject; } public function makeBookmark( $DatabaseObject = NULL, $TextObject = NULL, $MessageObject = NULL ) { if( $DatabaseObject == 'small' ) { $DatabaseObject = new Database(); } else if( $DatabaseObject == NULL ) { $DatabaseObject = new Database(); $TextObject = new Text(); $MessageObject = new Message(); } $BookmarkObject = new ControlBookmark(); $BookmarkObject->setObjects($DatabaseObject,$TextObject,$MessageObject); return $BookmarkObject; } }

• Flash AS3: How to Make scroll bar react to dynamic textfield movement?

  - by HeroicNate

  I've been looking for a tutorial and answer to this for a while but can't find what I'm looking for. I am loading html text into a dynamic textfield, and I have a scrollbar controlling the scroll using the code below. What I want to do is also add scroll up/down buttons and have the scroll bar move in relation to the text scroll. I was just going to use "tracklistingtext.scrollV -- " for the scroll buttons, but right now the scroll bar doesn't recognize the text movement. What do I need to do to get the scroll bar to listen to the text scroll position? var listTextreq:URLRequest=new URLRequest("tracklist.txt"); var listTextLoader:URLLoader = new URLLoader(); var bounds:Rectangle=new Rectangle(scrollMC.x,scrollMC.y,0,300); var scrolling:Boolean=false; function fileLoaded(event:Event):void { tracklistingtext.htmlText=listTextLoader.data; tracklistingtext.multiline=true; tracklistingtext.wordWrap=true; scrollMC.addEventListener(MouseEvent.MOUSE_DOWN, startScroll); stage.addEventListener(MouseEvent.MOUSE_UP, stopScroll); addEventListener (Event.ENTER_FRAME, enterHandler); } listTextLoader.addEventListener(Event.COMPLETE, fileLoaded); listTextLoader.load(listTextreq); function startScroll(e:Event):void { scrolling=true; scrollMC.startDrag(false,bounds); } function stopScroll(e:Event):void { scrolling=false; scrollMC.stopDrag(); } function enterHandler (e:Event):void { if (scrolling == true) { tracklistingtext.scrollV = Math.round(((scrollMC.y - bounds.y)/300)*tracklistingtext.maxScrollV); } } Any help is greatly appreciated.

• Show iPad keyboard on select, focus or always (jQuery)

  - by Ryan

  I have a web app that is using jQuery to replace the RETURN key with TAB so that when I user presses return the form is not submitted but rather the cursor moves to the next text field. This works in all browsers but only 1/2 works on the iPad. On the iPad the next field is highlighted but the keyboard is hidden. How can I keep the keyboard visible or force it somehow? Here's my code (thanks to http://thinksimply.com/blog/jquery-enter-tab): function checkForEnter (event) { if (event.keyCode == 13) { currentBoxNumber = textboxes.index(this); if (textboxes[currentBoxNumber + 1] != null) { nextBox = textboxes[currentBoxNumber + 1] nextBox.focus(); nextBox.select(); event.preventDefault(); return false; } } } Drupal.behaviors.formFields = function(context) { $('input[type="text"]').focus(function() { $(this).removeClass("idleField").addClass("focusField"); }); $('input[type="text"]').blur(function() { $(this).removeClass("focusField").addClass("idleField"); }); // replaces the enter/return key function with tab textboxes = $("input.form-text"); if ($.browser.mozilla) { $(textboxes).keypress (checkForEnter); } else { $(textboxes).keydown (checkForEnter); } };

• Is there any PDF parser written in objective-c or c?

  - by user549683

  I'm writing a pdf reader iPhone application. I know how to show pdf file in view using CGPDF** classes in iOS. What I want to do now is to search text in pdf file, and highlight the searched text. So, I need a library which can detect what text is in what position. Besides, I want the library able to handle unicode and Chinese characters. I've searched for a few days but still cannot find anything suitable. I've tried xpdf, but it is written in c++. I don't know how to use c++ code in iPhone app. I've also tried http://www.codeproject.com/KB/cpp/ExtractPDFText.aspx but it does not handle Chinese characters. I've tried to code by myself, but the encoding in PDF is really complicated. For example, I don't know what to refer to when I want to decode the text by the following font: 8 0 obj << /Type /Font /Subtype /Type0 /Encoding /Identity-H /BaseFont /RNXJTV+PMingLiU /DescendantFonts [ 157 0 R ] >> endobj 157 0 obj << /Type /Font /Subtype /CIDFontType2 /BaseFont /RNXJTV+PMingLiU /CIDSystemInfo << /Registry (Adobe) /Ordering (CNS1) /Supplement 0 >> /FontDescriptor 158 0 R /W 161 0 R /DW 1000 /CIDToGIDMap 162 0 R >> endobj 158 0 obj << /Type /FontDescriptor /Ascent 801 /CapHeight 711 /Descent -199 /Flags 32 /FontBBox [0 -199 999 801] /FontName /RNXJTV+PMingLiU /ItalicAngle 0 /StemV 0 /Leading 199 /MaxWidth 1000 /XHeight 533 /FontFile2 159 0 R >> endobj

• Magento - Add a button to system.xml with method attached to it

  - by vrnet

  Hi, I have created a module that has an "export like" method running regularly as defined in my module's cron area of the config.xml file. But I'd like to give the user the ability to run this export method on demand by adding a "Run now" button in the system configuration, thus using the system.xml file. It seems that the "frontend type" button may be working as I've tried and it adds a tiny clickable button in the config section. But I am not able to attach a method nor a label on the button itself. I thought about adding a button in the "Grid.php" file of the module but this not what I'd like to do as it does fit with my acl. Below is my system.xml file with the "button" frontend type. Does anyone have a clue on how to : add a label/value to the button add a class to the button add a method to call when the button is clicked Many thanks for your help ! <?xml version="1.0" encoding="UTF-8"?> <config> ... <fields> ... <run translate="label"> <label>Run now</label> <frontend_type>button</frontend_type> <backend_model>SOME BACKEND MODEL</backend_model> <sort_order>20</sort_order> <show_in_default>1</show_in_default> <show_in_website>1</show_in_website> <show_in_store>1</show_in_store> </run> </fields> ... </config>

• The "correct" way of using multilingual support

  - by Felipe Athayde

  I just began working with ASP.NET and I'm trying to bring with me some coding standards I find healthy. Among such standards there is the multilingual support and the use of resources for easily handling future changes. Back when I used to code desktop applications, every text had to be translated, so it was a common practice to have the language files for every languages I would want to offer to the customers. In those files I would map every single text, from button labels to error messages. In ASP.NET, with the help of Visual Studio, I have the resort of using the IDE to generate such Resource Files (from Tools - Generate Local Resource), but then I would have to fill my webpages with labels - at least that is what I've learned from articles and tutorials. However, such approach looks a bit odd and I'm tempted to guess it doesn't smell that good as well. Now to the question: 1) Should I keep every single text in my website as labels and manage its contents in the resource files? It looks/feels odd specially when considering a text with several paragraphs. 2) Whenever I add/remove something, e.g.: a button, to an aspx file I would have to add it to the resource file as well, because generating the resource file again would simply override all my previous changes to it. That doesn't feel like a reusable code at all for me. Any comment suggestion on this one? Perhaps I got it all wrong from tutorials as it doesn't seem like a standardized matter - specially if it required recompiling the entire application whenever some change has to be done.

• Filtering a select list via input box & jquery

  - by zSysop

  Hi all, I was wondering if i could get some help with filtering a select list using an input box via jquery. Here's what my js looks like, but it doesnt seem to work. I'm guessing this is because options within a select list are not hide-able. <script type="text/javascript"> $(document).ready(function() { $("#inputFilter").change(function() { var filter = $(this).val(); $("#selectList option").each(function() { var match = $(this).text().search(new RegExp(filter, "i")); if (match > 0) { $(this).show(); // Does not work } else $(this).hide(); }); }); }); </script> and here's my html <input id="inputFilter" /> <select id="selectList"> <option value="1111" text="1111 - London" /> <option value="1112" text="1111 - Paris" /> </select>

I have the following code in the form method: <form name="form1" method="post" action="checkpw.php"> Your Name: <table> <tr><td><input class="text" name="name" onBlur="capitalize(this);" maxlength=12 type="text" /></td></tr> </table> Password: <table> <tr><td><input class="text" name="passwd" maxlength=8 type="password" /></td></tr> <tr><td align="center"><br/> <input class="text" type="submit" name="submitbt" value="Login" /> </td></tr> </table> and the following checkpw.php: <?php // Clean up the input values $post = filter_input_array(INPUT_POST, array( 'name' => FILTER_SANITIZE_STRING, 'pw' => FILTER_SANITIZE_STRING, )); if (is_null($post) || in_array(null, $post)) { header("location:login.php"); return; // missing fields (or failed filter) } // pw is the password sent from the form $pw=$_POST['passwd']; $name=$_POST['name']; if($pw == 'testpass'){ header("location:index.php"); } else { header("location:wrong.php"); } ?> Is this a secure way to ensure the form is sent to the server and executed ONLY after the input values have been sanitized? Also, the $name value i want to pass it to index.php file. I insert a code in the index.php as follow: <?php echo $name ?> But it's empty. Any idea how to resolve it?

  - by wfoolhill

  I want to have "10^4 points" in bold as my x-axis label. I know how to make a simple label in bold: plot(1:10, xlab="") mtext(text="10 points", side=1, font=2, line=3) Thanks to this answer, I know how to make a label with a power of ten but nothing is in bold: mtext(text=expression(paste(10^4, " points")), side=1, font=2, line=3) Thanks to this answer, I also know how to make a label with a Greek letter in bold: mtext(text=expression(bold(paste(beta, "=", 10^1, " points"))), side=1, line=3) But still the power of ten is not in bold! It doesn't work either with bquote: mtext(text=bquote(bold(10^1~points)), side=1, line=3) Any idea? Here are some details about my system.

  Which form of mobile detection should I use and why? <meta name="viewport" content="width=320,initial-scale=1,maximum-scale=1.0,user-scalable=no" /> <link media="only screen and (max-device-width: 480px) and (min-device-width: 320px)" href="css/mobile.css" type= "text/css" rel="stylesheet"> <link media="handheld, only screen and (max-device-width: 319px)" href="css/mobile_simple.css" type="text/css" rel="stylesheet" /> Or include('mobile_device_detect.php'); $mobile = mobile_device_detect(); And why on earth would this: <?php if(strpos($_SERVER['HTTP_USER_AGENT'], 'iPhone') !== false) { ?> <meta name="viewport" content="width=320,initial-scale=1,maximum-scale=1.0,user-scalable=no" /> <link media="screen" href="css/mobile.css" type= "text/css" rel="stylesheet"> <?php } else { ?> <link media="screen" href="css/mobile_simple.css" type= "text/css" rel="stylesheet"> <?php } ?> ignore this css? body { background: -webkit-gradient(linear, left top, left bottom, from(#555), to(#000)); }

• TableTools only exporting single header row

  - by Rakeesh

  I am using the DataTable jquery plugin from: http://datatables.net/ I have a DataTable that has multi-row table header with colspan. Something like: <thead> <tr> <th>Level 1</th> <th colspan='2'>Level 1 - Item 1</th> <th colspan='2'>Level 1 - Item 2</th> </tr> <tr> <th>Level 2</th> <th>Level 2 - Item 1a</th> <th>Level 2 - Item 1b</th> <th>Level 2 - Item 2a</th> <th>Level 2 - Item 2b</th> </tr> </thead> However when I use the TableTools plugin to export then except for the "Print" option all the rest (Excel, CSV, Pdf etc) only has the "Level 2" header row and not the Level 1. Any suggestions on how to get it to export also Level 1?

• rails 3 actionmailer cannot send email

  - by lkahtz

  I am following Ryan Bates's tutorial on Rails 3 ActionMailer. I generate the mailer in terminal and then establish a setup_mail.rb under config/initializers. I keyed in the following code: ActionMailer::Base.smtp_settings={ :address => "smtp.gmail.com", :port => 587, :domail => "gmail.com", :user_name => "my_account_at_gmail", :password => "my_password", :authentication => "plain" , :enable_starttls_auto => true } My user_mailer.rb file goes like: class UserMailer < ActionMailer::Base default :from => "[email protected]" def registration_confirmation(user) mail(:to => user.email,:subject => "registered") end end I tested in rails console: u=User.first UserMailer.registration_confirmation(u).deliver it displays: #<Mail::Message:2194479560, Multipart: false, Headers: <Date: Sat, 26 Feb 2011 14:42:06 +0800>, <From: [email protected]>, <To: [email protected]>, <Message-ID: <[email protected]>>, <Subject: registered>, <Mime-Version: 1.0>, <Content-Type: text/plain>, <Content-Transfer-Encoding: 7bit>> BUT I never received the email here... Why? How can I solve this? I guess it is some problem on send_mail.rb file..
