• 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>

• 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...

• suppress error using fread()

  - by Mikey1980

  I wrote a script for screen pops from our soft phone that locates a directory listing for the caller but occasionally they get "Can't read input stream" and the rest of the script quits. Does anyone have any suggestions on how to suppress error the error message and allow the rest of the script to run? Thanks! $i=0; $open = fopen("http://www.411.ca/whitepages/?n=".$_GET['phone'], "r"); $read = fread($open, 9024); fclose($open); eregi("'/(.*)';",$read,$got); $tv = ereg_replace('[[:blank:]]',' ',$got[1]); $url = "http://www.411.ca/".$tv; while ($name=="unknown" && $i < 15) { ## try 15 times before giving up $file = @ fopen($fn=$url,"r") or die ("Can't read input stream"); $text = fread($file,16384); if (preg_match('/"name">(.*?)<\/div>/is',$text,$found)) { $name = $found[1]; } if (preg_match('/"phone">(.*?)<\/div>/is',$text,$found)) { $phone = $found[1]; } if (preg_match('/"address">(.*?)<\/div>/is',$text,$found)) { $address = $found[1]; } fclose($file); $i++; }

• Bootstrap inline button dropdown within <p> jumbotron

  - by C.B.

  Currently I have a jumbotron setup with some paragraph text, and I would like to stick a button dropdown inline with the text. Dropdown button <span class="btn-group"> <button type="button" class="btn btn-default dropdown-toggle" data-toggle="dropdown"> Button... <span class="caret"></span> </button> <ul class="dropdown-menu" role="menu"> <li><a href="#">Opt 1</a></li> <li><a href="#">Opt 2</a></li> </ul> </span> Jumbotron <div class="jumbotron"> <h1>Hello!</h1> <p>Welcome</p> <p>Another paragraph <!-- dropdown is here --> </p> </div> <!-- jumbotron --> If the dropdown is within the <p> tag, it does not "dropdown" (but renders). If it is outside of the <p> tag it functions fine, but I would like it to be inline with the text and need the text to be in the <p> tag to get the style. Any ideas? Things to note -- If I replace the <span> tags with <div> tags, it will work fine within the <p> tags, but won't be inline.

• How to fix a slow scrolling table view

  I have a table view that's scrolling slowly. Does anyone know why that might be? There is an image for each row, but even after the images are loaded it still stutters and scrolls slowly. thanks for any help here's my code: - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { static NSString *simpleTableIdentifier = @"SimpleTableCell"; SimpleTableCell *cell = (SimpleTableCell *)[tableView dequeueReusableCellWithIdentifier:simpleTableIdentifier]; if (cell == nil) { NSArray *nib = [[NSBundle mainBundle] loadNibNamed:@"SimpleTableCell" owner:self options:nil]; cell = [nib objectAtIndex:0]; } // Get item from tableData NSDictionary *item = (NSDictionary *)[displayItems objectAtIndex:indexPath.row]; // display the youdeal deal image photoString = [item objectForKey:@"image"]; UIImage *image = [UIImage imageWithData:[NSData dataWithContentsOfURL:[NSURL URLWithString:photoString]]]; cell.titleLabel.text = [item objectForKey:@"supercat"]; cell.descriptionLabel.text = [item objectForKey:@"title"]; NSString *convertedLeftCount = [NSString stringWithFormat:@"%@",[item objectForKey:@"left_count"]]; cell.amountLabel.text = convertedLeftCount; cell.thumbnailImageView.image = image; cell.priceLabel.text = [item objectForKey:@"cat"]; return cell; }

• Multiple plugin instance loading with MEF

  - by Dave

  In my last application, using MEF to load plugins went just fine, but now I'm running into a new issue. I have a solution for it that I explain at the end of this question, but I'm looking for other ways to do it. Let's say I have an interface called ApplianceInterface. I also have two plugins that inherit from ApplianceInterface, let's call them Blender and Processor. Now, I would like to have multiple Blenders and Processors in my application, but I am not sure how to instantiate them properly. Before, I would simply use the ImportMany attribute and upon calling ComposeParts, my application would load Blender and Processor. For example: [ImportMany(typeof(ApplianceInterface))] private IEnumerable<ApplianceInterface> Appliances { get; set; } and my Blender and Processor plugins would be attributed like this: [PartCreationPolicy(CreationPolicy.NonShared)] [Export(typeof(MyInterface)] public class Blender : ApplianceInterface { ... } but what this ends up doing for me is populating Appliances with one Blender and one Processor. I need to be able to create an arbitrary number of Blender and Processor objects. Now, from the documentation I understand that [PartCreationPolicy(CreationPolicy.NonShared)] is what allows MEF to create a new instance each time, but is there a similar "magical" way to create a specific number of instances of something using MEF? Up until now, I've relied on [Import] and [ImportMany] to resolve the assemblies. Is my only option to use a global container, and then resolve the export manually using GetExportedValue<? I have tried GetExportedValue< and that implementation does work fine for me, but I was just curious if there is a better, more accepted way to do it.

• Applying MVVM to ASP.NET

  - by Moussa

  Hi everyone, I am learning MVVM and i want to use it with ASP.NET. Some of the examples that i found on the internet uses XAML for the view. Is there a way to use a regular ASP.NET page instead of XAML for the view? Here is a XAML example: <UserControl x:Class="MVVMExample.DetailView" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"> <Grid x:Name="LayoutRoot" Background="White" DataContext="{Binding CurrentContact}"> <Grid.RowDefinitions> <RowDefinition/> <RowDefinition/> </Grid.RowDefinitions> <Grid.ColumnDefinitions> <ColumnDefinition/> <ColumnDefinition/> </Grid.ColumnDefinitions> <TextBlock Text="Name:" HorizontalAlignment="Right" Margin="5"/> <TextBlock Text="{Binding FullName}" HorizontalAlignment="Left" Margin="5" Grid.Column="1"/> <TextBlock Text="Phone:" HorizontalAlignment="Right" Margin="5" Grid.Row="1"/> <TextBlock Text="{Binding PhoneNumber}" HorizontalAlignment="Left" Margin="5" Grid.Row="1" Grid.Column="1"/> </Grid> </UserControl> Thank you for your time.

• pre_replace multi-dimensional array problem

  - by Martin

  I want to replace word groups by links. I use a multi-dimensional array to define these (in the real world there will be thousands of them). Here's the code: $text = "<html><body><pre> Here is Foo in text. Now come Baz? and Bar-X. Replace nothing here: Foo (followed by brackets). </pre></body></html>"; $s = array( array("t" => "Foo", "u" => "http://www.foo.com", "c" => "foo"), array("t" => "Baz?", "u" => "http://www.baz.net", "c" => "test"), array("t" => "Bar-X", "u" => "http://www.baz.org", "c" => "test") ); foreach ($s as $i => $row) { $replaced = preg_replace('/(?=\Q'.$row["t"].'\E[^(]+$)\b\Q'.$row["t"].'\E\b/m', '<a href="'.$row["u"].'" class="'.$row["c"].'">'.$row["t"].'</a>', $text); } echo $replaced; ?> The problem is that only one array element is replaced and not all. It's something about $text in peg_replace(). Anyone got a hint for me? Thanks!

• Keyboard not dismissed

  - by sgosha

  I am developing a messaging application that have SMS.app-like UI. Conversation screen has text input field at the bottom which is moved up with keyboard. Tapping on conversation area dismisses keyboard by calling resignFirstResponder method on UITextView that we use. This usually works fine, but users report a weird bug which I can't reproduce and fix. People say that sometimes onscreen keyboard doesn't go away when they tap on conversation area, though text input field loses input focus. Once the view enters that abnormal state users are able to type with keyboard, but text that is being entered is not visible anywhere. This bug happens in one of conversation views and since then no one text input field in other views doesn't work as expected. The only way to stop this weird behavior is killing application from multitasking bar. Even more weird thing is that keyboard stays visible while navigating between view controllers in UINavigationController. I noticed two things: - if tap on ' Anyone else experiencing same problems. Any ideas on what may cause this bug?

• How to wait for ajax validation to complete before submitting a form?

  - by Jung

  Having a problem where the form submits before the validateUsername function has a chance to complete the username check on the server-side. How do I submit the form only after the validateUsername function completes? Hope this is clear... form.submit(function(){ if (validateUsername() & validateEmail() & validatePassword()) { return true; } else { return false; } }); function validateUsername(){ usernameInfo.addClass("sign_up_drill"); usernameInfo.text("checking..."); var b = username.val(); var filter = /^[a-zA-Z0-9_]+$/; $.post("../username_check.php",{su_username:username.val()},function(data) { if (data=='yes') { username.addClass("error"); usernameInfo.text("sorry, that one's taken"); usernameInfo.addClass("error"); return false; } else if (!filter.test(b)) { username.addClass("error"); usernameInfo.text("no funny characters please"); usernameInfo.addClass("error"); return false; } else { username.removeClass("error"); usernameInfo.text("ok"); usernameInfo.removeClass("error"); return true; } }); }

• problem with converting simple code from Winform to silverlight app.

  - by Sara

  Hi. I have this code for window form application and I have been attempting to convert it to a Silverlight application but it does not work!. There is a Textbox and I attached KeyDown event handler to it. when the user press the arrow key ( left or right) while the focus on the textbox, it will write . or -. When it is window form i used e.KeyCode and Keys.Right and its works great but when it is silverlight I used e.Key and key.Right and the program doesn't work good because the arrows do the 2 functions moving and write ./-. How I can work this out in Silverlight? (My English not good) The code ( window form): private void textBox1_KeyDown(object sender, KeyEventArgs e) { if (sender is TextBox) { TextBox textBox = (TextBox)sender; if (e.KeyCode == Keys.Left || e.KeyCode == Keys.Right) { e.Handled = true; char insert; if (e.KeyCode == Keys.Left) { insert = '.'; } else { insert = '-'; } int i = textBox.SelectionStart; textBox.Text = textBox.Text.Insert(i, insert.ToString()); textBox.Select(i + 1, 0); } } } (and Silverlight): private void textBox1_KeyDown(object sender, KeyEventArgs e) { if (sender is TextBox) { TextBox textBox = (TextBox)sender; if (e.Key == Key.Left || e.Key == Key.Right) { e.Handled = true; char insert; if (e.Key == Key.Left) { insert = '.'; } else { insert = '-'; } int i = textBox.SelectionStart; textBox.Text = textBox.Text.Insert(i, insert.ToString()); textBox.Select(i + 1, 0); } } } I don't understand, is there huge different effect between using Keycode/Keys and Key/Key or because something else?

• How would I make this faster? Parsing Word/sorting by heading [on hold]

  - by Doof12

  Currently it takes about 3 minutes to run through a single 53 page word document. Hopefully you all have some advice about speeding up the process. Code: import win32com.client as win32 from glob import glob import io import re from collections import namedtuple from collections import defaultdict import pprint raw_files = glob('*.docx') word = win32.gencache.EnsureDispatch('Word.Application') word.Visible = False oFile = io.open("rawsort.txt", "w+", encoding = "utf-8")#text dump doccat= list() for f in raw_files: word.Documents.Open(f) doc = word.ActiveDocument #whichever document is active at the time doc.ConvertNumbersToText() print doc.Paragraphs.Count for x in xrange(1, doc.Paragraphs.Count+1):#for loop to print through paragraphs oText = doc.Paragraphs(x) if not oText.Range.Tables.Count >0 : results = re.match('(?P<number>(([1-3]*[A-D]*[0-9]*)(.[1-3]*[0-9])+))', oText.Range.Text) stylematch = re.match('Heading \d', oText.Style.NameLocal) if results!= None and oText.Style != None and stylematch != None: doccat.append((oText.Style.NameLocal, oText.Range.Text[:len(results.group('number'))],oText.Range.Text[len(results.group('number')):])) style = oText.Style.NameLocal else: if oText.Range.Font.Bold == True : doccat.append(style, oText) oFile.write(unicode(doccat)) oFile.close() The for Paragraph loop obviously takes the most amount of time. Is there some way of identifying and appending it without going through every Paragraph?

• How to use clearInterval() and then make changes to the DOM?

  - by George D.

  I have this code and the problem I have is that I want to stop the loop and then replace the text 'Done!' that comes from the sms-loader.php script with the "textnew" string. Problem is that the loop occurs one more time so the text in the div.checkstatus field is again replaced by the calling php script. The strange thing is that I see the log message and again I get a new (and final) request, although the ordering is the opposite (first stop then replace text()) in my script. I need to understand why this is happening. $(document).ready(function() { var interval = ""; $('.checkstatus').each(function(){ var msgid = $(this).data('msg') $this = $(this), hid = $this.data('history'), textnew = '<a href="sms-dstatus.php?id='+msgid+'&sid=' +hid+ '&amp;keepThis=true&amp;TB_iframe=true&amp;height=430&amp;width=770" title="Delivery Status" class="thickbox"><img src="../template/icons/supermini/chart_curve.png" alt="status" width="16" height="16" /></a>'; interval = setInterval(function() { $this.load('../pages/sms-loader.php?id='+msgid); // stop the loop if($this.text()=='Done!'){ // stop it clearInterval(interval); console.log(textnew); this.html(textnew); /// this line is the problem } }, 5000); // 5 secs }); });

• How to hide an dom element after creating it on the fly with Jquery ?

  - by ismaelsow

  I am trying to build a form where users can add a text field by clicking on a "add option" button. They can also remove added fields by a "remove option" link created on the fly by Jquery, along with the text field. My code looks like this : $(document).ready(function(){ $("#add_option").click(function(){ var form = $("form"); var input_field = '<input type="text" />'; var delete_link = '<a href="#">remove</a>'; form.append(input_field + delete_link); return false; }); $("a").click(function(){ alert('clicked'); return false; }); }); This code is not working : when I click on the "add_option" button, a new text field and the "delete_link" appear. But when clicking on the "delete_link" created by JQuery, the browser follows the link instead of launching a pop-up displaying "clicked". Any idea ? Thanks !

• My java program seems to be skipping over the try{}, executing the catch{} and then throwing a NullPointerException. What should I do?

  - by Matt Bolopue

  I am writing a program that calculates the number of words, syllables, and sentences in any given text file. I don't need help finding those numbers, however my program (which currently should only find the number of words in the text file) will not import the text file even when I type in the name of the file correctly. The text file is in the same folder as the source code. Instead it tells me every time that what I typed in has the wrong file extension (see my catch{}) and then proceeds to throw a null pointer. I am at a loss for what could be causing it. Any suggestions? import java.io.*; import java.util.*; public class Reading_Lvl_Calc { /** * @param args */ public static void main(String[] args) { // TODO Auto-generated method stub int words = 0; String fileName; Scanner scan; Scanner keyread = new Scanner(System.in); System.out.println("Please enter a file name (or QUIT to exit)"); fileName = keyread.nextLine(); File doc = new File(fileName); //while(scan.equals(null)){ try { scan = new Scanner(doc); } catch(Exception e) { if(fileName.substring(fileName.indexOf(".")) != ".txt") System.out.println("I'm sorry, the file \"" + fileName + "\" has an invalid file extension."); else System.out.println("I am sorry, the file \"" + fileName + " \" cannot be found.\n The file must be in the same directory as this program"); scan = null; } // } while(scan.hasNext()){ words++; scan.next(); } System.out.println(words); } }

• Stop writing blank line at the end of CSV file (using MATLAB)

  - by Grant M.

  Hello all ... I'm using MATLAB to open a batch of CSV files containing column headers and data (using the 'importdata' function), then I manipulate the data a bit and write the headers and data to new CSV files using the 'dlmwrite' function. I'm using the '-append' and 'newline' attributes of 'dlmwrite' to add each line of text/data on a new line. Each of my new CSV files has a blank line at the end, whereas this blank line was not there before when I read in the data ... and I'm not using 'newline' on my final call of 'dlmwrite'. Does anyone know how I can keep from writing this blank line to the end of my CSV files? Thanks for your help, Grant EDITED 5/18/10 1:35PM CST - Added information about code and text file per request ... you'll notice after performing the procedure below that there appears to be a carriage return at the end of the last line in the new text file. Consider a text file named 'textfile.txt' that looks like this: Column1, Column2, Column3, Column4, Column 5 1, 2, 3, 4, 5 1, 2, 3, 4, 5 1, 2, 3, 4, 5 1, 2, 3, 4, 5 1, 2, 3, 4, 5 Here's a sample of the code I am using: % import data importedData = importdata('textfile.txt'); % manipulate data importedData.data(:,1) = 100; % store column headers into single comma-delimited % character array (for easy writing later) columnHeaders = importedData.textdata{1}; for counter = 2:size(importedData.textdata,2) columnHeaders = horzcat(columnHeaders,',',importedData.textdata{counter}); end % write column headers to new file dlmwrite('textfile_updated.txt',columnHeaders,'Delimiter','','newline','pc') % append all but last line of data to new file for dataCounter = 1:(size(importedData.data,2)-1) dlmwrite('textfile_updated.txt',importedData.data(dataCounter,:),'Delimiter',',','newline','pc','-append') end % append last line of data to new file, not % creating new line at end dlmwrite('textfile_updated.txt',importedData.data(end,:),'Delimiter',',','-append')

• C# textbox cursor positioning

  - by Jim

  I feel like I am just missing a simple property, but can you set the cursor to the end of a line in a textbox? private void txtNumbersOnly_KeyPress(object sender, KeyPressEventArgs e) { if (Char.IsDigit(e.KeyChar) || e.KeyChar == '\b' || e.KeyChar == '.' || e.KeyChar == '-') { TextBox t = (TextBox)sender; bool bHandled = false; _sCurrentTemp += e.KeyChar; if (_sCurrentTemp.Length > 0 && e.KeyChar == '-') { // '-' only allowed as first char bHandled = true; } if (_sCurrentTemp.StartsWith(Convert.ToString('.'))) { // add '0' in front of decimal point t.Text = string.Empty; t.Text = '0' + _sCurrentTemp; _sCurrentTemp = t.Text; bHandled = true; } e.Handled = bHandled; } After testing for '.' as first char, the cursor goes before the text that is added. So instead of "0.123", the results are "1230." without moving the cursor myself. I also apologize if this is a duplicate question.

• How to understand the BODYSTRUCTURE information returned by IMAP servers?

  - by Tony

  I'm using python's IMAPClient to retrieve email messages from IMAP server. One of the attributes I retrieve is BODYSTRUCTURE. However, I can't find any documentation on how to interpret the return values. Here's the body structure that IMAP server returns 16:12.679978 < FLAGS (NotJunk $NotJunk \Seen) BODYSTRUCTURE ((("TEXT" "PLAIN" ("CHARSET" "us-ascii") NIL NIL "QUOTED-PRINTABLE" 4888 170 NIL NIL NIL)("TEXT" "HTML" ("CHARSET" "us-ascii") NIL NIL "QUOTED-PRINTABLE" 32407 479 NIL NIL NIL) "ALTERNATIVE" ("BOUNDARY" "Apple-Mail=_3AAA7CD7-3B07-406A-83CB-2C7762C3306E") NIL NIL)("APPLICATION" "PKCS7-SIGNATURE" ("NAME" "smime.p7s") NIL NIL "BASE64" 2414 NIL ("ATTACHMENT" ("FILENAME" "smime.p7s")) NIL) "SIGNED" ("BOUNDARY" "Apple-Mail=_DF4FE6BB-F796-46D7-A593-9723F4315DD2" "MICALG" "sha1" "PROTOCOL" "application/pkcs7-signature") NIL NIL)) Here's the same body structure parsed to python type. "BODYSTRUCTURE": [ [ [ [ "TEXT", "PLAIN", [ "CHARSET", "us-ascii" ], null, null, "QUOTED-PRINTABLE", 4888, 170, null, null, null ], [ "TEXT", "HTML", [ "CHARSET", "us-ascii" ], null, null, "QUOTED-PRINTABLE", 32407, 479, null, null, null ], "ALTERNATIVE", [ "BOUNDARY", "Apple-Mail=_3AAA7CD7-3B07-406A-83CB-2C7762C3306E" ], null, null ], [ "APPLICATION", "PKCS7-SIGNATURE", [ "NAME", "smime.p7s" ], null, null, "BASE64", 2414, null, [ "ATTACHMENT", [ "FILENAME", "smime.p7s" ] ], null ] ], "SIGNED", [ "BOUNDARY", "Apple-Mail=_DF4FE6BB-F796-46D7-A593-9723F4315DD2", "MICALG", "sha1", "PROTOCOL", "application/pkcs7-signature" ], null, null ], The arrays don't seems to be constant length. What each element of the array stand for?
