• How do I create a Magento module or widget that will appear on the shopping cart page?

  - by user303449

  I’m having a lot of trouble understanding how to create a module that will add an extra button to the shopping cart page. I found lots of info on payment modules and stand-a-lone page modules, but nothing for this. I simply need to add a button underneath the regular “Checkout” button that can post item data to another website. I’ve created a module but can’t get Magento to recognize it and display the button on that spot. Any help would be greatly appreciated, even just sending me to an existing tutorial that I haven’t been able to find. Thanks.

• Jquery Slider PNG black borders IE8

  - by Thomas

  Greetings, I'm having a lot of trouble with the IE8 buy of getting black borders when using a JQUERY slider, with PNG transparent images. Using a slightly modified version of the Nivio slider. I have searched high and low for fixes and blocks of code but so far none have worked. What happens is that as soon as the img cycles it gets the black border and looks like shit (only in IE8). Does anyone know a working fix for this? Or do we just have to ban IE from all computers?

• How do I attach an event handler to the document or window in GWT?

  - by Raph Levien

  In a GWT app centered around a canvas, I'm having trouble keeping focus directed in the right place - particularly for keyboard shortcuts. For now, I've wrapped the canvas in a FocusPanel, but that causes the canvas to not respond to the RequiresResize protocol, because FocusPanel does not plumb that. A second (related, I think) problem is that the FocusPanel is not getting Ctrl-A keypress events at all (tested on Mac Chrome). I can get Ctrl-Z and other keys (such as arrows) just fine. In a pure JavaScript world, I think the best answer to this would be to attach mouse and key handlers to the document or window object (I'm not positive which is better). However, I don't see an obvious way to do this in GWT - in particular, the Document and Window classes lack methods for attaching these kind of event handlers? Anyone know how to do it, or, perhaps, to solve the more general problem of keeping focus on an appropriate widget able to handle keyboard shortcuts?

• CruiseControl.NET merge nunit and nant output

  - by JK

  I've just started using ccnet so I'm having trouble understanding why the merging of nant and nunit outputs are not working. I've setup my ccnet.config with typical values as found on google: <merge> <files> <file>D:\ccnet\path1\nant-results.xml</file> <file>D:\ccnet\path2\TestResult.xml</file> </files> </merge> <xmllogger /> Nant and ccnet are half working: if I deliberately put in a code error, then ccnet will say build failed. The same happens if I deliberately put in a failing test, ccnet will say build failed. But the ViewBuildReport.aspx page does not show any of the output from nant or nunit. Obviously I must be missing something, but I don't know what, any ideas? Thanks, JK

• Problem with url_for in ActionMailer template

  - by macek

  I'm attempting to provide a confirmation link in my user welcome email and I'm getting the following Rails error: Need controller and action! It makes a fuss about this line: <p>Please take a moment to activate your account by going to: <%= link_to confirm_user_url(:id => @user.confirmation_code) %>.</p> In my development.rb environment, I have the following line: config.action_mailer.default_url_options = { :host => "localhost", :port => 3000 } There's no problem with the @user variable. I've tested the email with things like @user.username and @user.confirmation_code. I'm only getting trouble with url_for and named routes like confirm_user_url. When I check my routes with rake routes, confirm_user shows up, so it's not an issue with the named route not existing. I can't seem to figure it out. What gives?

• Best tool for monitoring Coldfusion interoperability with .Net web service

  - by John Galt

  Is there a tool to see the message sent to webservice hosted on an IIS server? I have a webservice written in .Net and our ColdFusion people are having trouble building a "complex" parameter. This problem is described from a ColdFusion perspective at: adobe forum question It runs when called from a .net client. While hosted on a server inside our LAN, I put it out on a public server so the WSDL could be viewed: please take a quick look at this WSDL here When the CF developer runs her code, she gets: java.lang.IllegalArgumentException: argument type mismatch ...and I am wondering if there is a tool I could run on the server that hosts my webservice to see if it is even entering the WS or is being rejected by Java code that CF uses and is not really even getting to my webservice.

• Restoring a saved opengl ES buffer (i.e. writing it back to screen)

  - by Adam

  I'm writing an iPhone app where I need to save and load the screen contents. I was able to save the screen using glReadPixels(), but since there's no glDrawPixels() in openGL ES, I'm having a lot of trouble restoring that buffer to the screen. I gather that I need to save the screen as a texture: http://stackoverflow.com/questions/708760/what-is-the-equivalent-of-gldrawpixels-in-opengl-es-1-1 But I'm not sure how to implement this. Does anyone have or know of any code samples that do this? I'm an openGL noob, so any help would be greatly appreciated :)

• Classic asp paging and session state

  - by flavour404

  Hi, Working on a classic asp page that uses paging. The error I am having a problem with is this: Lets say that you have 5 pages returned in your record set and you are on page 2. You leave and come back, you then press the link for page 3, the trouble is your session has timed out. I don't know why this happens but the page is reloaded, but the session check is bypassed and of course when the page attempts to retrieve the record set the session variables are now empty so I am getting a message stating: error near ',' line 1, because now the query is defunct. How do I get around this? Thanks, Ron.

• arg function not using URL alias

  - by cinqoTimo

  I am running Drupal 6, and I'm using PHP for block visibility. <?php $city = arg(0); $page = arg(1); if ($city == 'tampa' && $page != 'art'){ return 'TRUE'; } else{ return FALSE; } ?> I was having trouble with this block of code, so I decided to insert: <?php print arg(0).arg(1); ?> in my page.tpl.php. What I found was that on some of my pages, arg(0) was showing 'node' when the URL is actually 'tampa', and of course, arg(1) is showing the node ID. However, on other pages, such as my calendar, arg(0) is actually showing 'tampa' instead of 'node'. I have used this a lot in the past, and have never had this problem. Is there a reason why Drupal is disregarding my aliases on certain pages? If so, how can I fix it?

• What does :this means in Ruby on Rails?

  - by Marco

  Hi, I'm new to the Ruby and Ruby on Rails world. I've read some guides, but i've some trouble with the following syntax. I think that the usage of :condition syntax is used in Ruby to define a class attribute with some kind of accessor, like: class Sample attr_accessor :condition end that implicitly declares the getter and setter for the "condition" property. While i was looking at some Rails sample code, i found the following examples that i don't fully understand. For example: @post = Post.find(params[:id]) Why it's accessing the id attribute with this syntax, instead of: @post = Post.find(params[id]) Or, for example: @posts = Post.find(:all) Is :all a constant here? If not, what does this code really means? If yes, why the following is not used: @posts = Post.find(ALL) Thanks

• How to normalize a database where different user groups have different kinds of profiles?

  - by Stephen

  My application database has a Groups table that separates users into logical roles and defines access levels (admin, owner, salesperson, customer service, etc.) Groups has many Users. The Users table contains login details such as username and password. Now I wish to add user profiles to my database. The trouble I'm having (probably due to my relative unfamiliarity with proper database normalization) is that different user groups have different kinds of profiles. Ergo, a salesperson's profile will include his commission percentage, whereas an admin or customer service would not need this value. So, would the proper method be to create a unique profile table for each group? (e.g. admin_profiles, or salesperson_profiles). or is there a better way that combines certain details in a generic profile, while some users have extended info. And if so, whats a good example of how to do this with the commission example given?

• Zebra Label Printer with C#

  - by user3702654

  I'm having trouble printing a label using ZDesigner GK420T using C# .NET. I converted the following string to Bytes and passed into the printer. ^XA ^FO3,3^AD^FDZEBRA^FS ^XZ The expected outcome was that the printer was supposed to print 'ZEBRA' but it didn't. My C# Code: StringBuilder sb; sb = new StringBuilder(); if (frmPrintJob._type != 1) { sb.AppendLine("^XA"); sb.AppendLine("^FO3,3^AD^FDZEBRA^FS"); sb.AppendLine("^XZ"); } int intTotalPrinted = 0; for (int i = 1; i <= NoOfCopies; i++) { if (RawPrinterHelper.SendStringToPrinter(PrinterName, sb.ToString()) == true) intTotalPrinted++; } What am I doing wrong here? Do I need any extra code?

• Can Eclipse not hard-code ECLIPSE_HOME when exporting build.xml?

  - by stevex

  I have an Eclipse project that I'm attempting to set up to build both with Eclipse and externally with Ant. It seems like a good way to do this is to have Eclipse generate a build.xml file that I can then use with ant. I'd like to set it up so the build.xml can be regenerated from Eclipse whenever the need arises, which means no hand-editing the build.xml file. But Eclipse writes one entry in there that has a hard-coded path to a directory on my computer, which makes it unsuitable for checking in to a source repository. Specifically it's this entry that's the trouble: <property name="ECLIPSE_HOME" value="D:/Eclipse/Eclipse Galileo (3.5) SR1"/> Is there some way to have Eclipse not output this line, or to make it a relative reference or something that makes sense to check in?

• Recursive Functions for Beginners?

  - by cam

  I'm looking for a few recursive function examples, preferably ones that show increase in complexity. I understand basic recursive functions, but I'm having trouble implementing them in my code. I've never used them in my code before, and I know it doesn't always call for it, but I'd like to try. Is there a good resource with examples, and maybe challenges of some sort? Or even some simple math problems (Project Euler-style?) that I could use recursion on? For examples, I prefer C#, but anything works.

• Browser not handling exception from AJAX panel, ASP.NET c#

  - by Grant

  Hi, i am having trouble catching errors in an AJAX panel. Even when i throw an exception in the c# code behind the front end completely ignores it. Here is the code i have setup, can anyone see why? I ideally want to show a js alert window on error. Code Behind: protected void btnX_Click(object sender, EventArgs e) { throw new ApplicationException("test"); } protected void ScriptManager_AsyncPostBackError(object sender, AsyncPostBackErrorEventArgs e) { ScriptManager.AsyncPostBackErrorMessage = e.Exception.Message; } Markup: <script type="text/javascript" language="javascript"> Sys.WebForms.PageRequestManager.getInstance().add_endRequest(EndRequestHandler); function EndRequestHandler(sender, e) { window.alert(e.get_error().name); } </script> <asp:ScriptManager ID="ScriptManager" runat="server" AllowCustomErrorsRedirect="true" OnAsyncPostBackError="ScriptManager_AsyncPostBackError" />

• How do I make lambda functions generic in Scala?

  - by Electric Coffee

  As most of you probably know you can define functions in 2 ways in scala, there's the 'def' method and the lambda method... making the 'def' kind generic is fairly straight forward def someFunc[T](a: T) { // insert body here what I'm having trouble with here is how to make the following generic: val someFunc = (a: Int) => // insert body here of course right now a is an integer, but what would I need to do to make it generic? val someFunc[T] = (a: T) => doesn't work, neither does val someFunc = [T](a: T) => Is it even possible to make them generic, or should I just stick to the 'def' variant?

• Help with running crontab from root

  - by user242065

  Im using OSX and having trouble getting a cron job to run. I type the following: $ sudo -i $ crontab -e I then enter: * * * * * root ifconfig en0 down > /dev/null 0 19 * * * root ifconfig en0 down > /dev/null 0 7 * * * root ifconfig en0 up > /dev/null and no success, the first line is for testing. I want it to shut off my internet. The next two lines I plan to leave in, once I get this working. If I type this in to the terminal the internet goes off ifconfig en0 down Why is my cron job not shutting down the internet? FYI: This is a follow up question from http://stackoverflow.com/questions/3027362/how-can-i-write-a-cron-job-that-will-block-my-internet-from-7pm-to-7am-so-i-can most of the comments there are people making fun of me.

• Android how do I wait until a service is actually connected?

  - by Ryan

  I have an Activity calling a Service defined in IDownloaderService.aidl: public class Downloader extends Activity { IDownloaderService downloader = null; // ... In Downloader.onCreate(Bundle) I tried to bindService Intent serviceIntent = new Intent(this, DownloaderService.class); if (bindService(serviceIntent, sc, BIND_AUTO_CREATE)) { // ... and within the ServiceConnection object sc I did this public void onServiceConnected(ComponentName name, IBinder service) { Log.w("XXX", "onServiceConnected"); downloader = IDownloaderService.Stub.asInterface(service); // ... By adding all kinds of Log.xx I found that the code after if(bindService(...)) actually goes BEFORE ServiceConnection.onServiceConnected is being called - that is, when downloader is still null - which gets me into trouble. All the samples in ApiDemos avoid this timing problem by only calling services when triggered by user actions. But what should I do to right use this service after bindService succeeds? How can I wait for ServiceConnection.onServiceConnected being called reliably?

• What method of UIView gets called when instantiated from a NIB?

  - by retailevolved

  I have a simple custom view that is connected via outlet to a NIB. For this particular view, there are actions that I would like to perform on the view when it is initialized, no matter what NIB it is on. Trouble is, neither the (id)init or the (id)initWithFrame:(CGRect)frame methods are getting called on the custom view. Which method gets called on a UIView when it is instantiated from a NIB? I would just use the view controller and viewDidLoad method except that this particular view appears on a lot of different NIBs.

• Lua - How to use functions from another script

  - by Person

  I'm wondering how to use functions from another script in Lua. For example, say GameObjectUtilities holds functions that many GameObject scripts will use. The Slime (a GameObject) script wants to use a function in GameObjectUtilities. I'm having trouble getting this to work. I've looked here, but I still don't really fully understand. Do I need to create a module or a table to hold the functions in GameObjectUtilities for the functions in it to be used in other scripts? If so, what is the best way to go about this?

• hierarchical data from self referencing table in tree form

  - by Beta033

  It looks like this has been asked and answered in all the simple cases, excluding the one that I'm having trouble with. I've tried using a recursive CTE to generate this; however maybe a cursor would be better? Or maybe a set of recursive functions will do the trick? Can this be done in a cte? consider the following table PrimaryKey ParentKey 1 NULL 2 1 3 6 4 7 5 2 6 1 7 NULL should yield PK 1 -2 --5 -6 --3 7 -4 where the number of - marks equal the depth, my primary difficulty is the ordering.

• Setting a form field's value during validation

  - by LaundroMat

  I read about this issue already, but I'm having trouble understanding why I can't change the value of a form's field during validation. I have a form where a user can enter a decimal value. This value has to be higher than the initial value of the item the user is changing. During clean(), the value that was entered is checked against the item's previous value. I would like to be able to re-set the form field's value to the item's initial value when a user enters a lower value. Is this possible from within the clean() method, or am I forced to do this in the view? Somehow, it doesn't feel right to do this in the view... (To make matters more complicated, the form's fields are built up dynamically, meaning I have to override the form's clean() method instead of using the clean_() method).

• .htaccess url rewrite with ssl redirection

  - by Stuart McAlpine

  I'm having trouble combining a url query parameter rewrite (fancy-url) with a .htaccess ssl redirection. My .htaccess file is currently: Options +FollowSymLinks Options -Indexes ServerSignature Off RewriteEngine on RewriteBase / # in https: process secure.html in https RewriteCond %{server_port} =443 RewriteCond $1 ^secure$ [NC] RewriteRule ^(.+).html$ index.php?page=$1 [QSA,L] # in https: force all other pages to http RewriteCond %{server_port} =443 RewriteCond $1 !^secure$ [NC] RewriteRule ^(.+).html$ http://%{HTTP_HOST}%{REQUEST_URI} [QSA,N] # in http: force secure.html to https RewriteCond %{server_port} !=443 RewriteCond $1 ^secure$ [NC] RewriteRule ^(.+).html$ https://%{HTTP_HOST}%{REQUEST_URI} [QSA,N] # in http: process other pages as http RewriteCond %{server_port} !=443 RewriteCond $1 !^secure$ [NC] RewriteRule ^(.+).html$ index.php?page=$1 [QSA,L] The fancy-url rewriting is working fine but the redirection to/from https isn't working at all. If I replace the 2 lines containing RewriteRule ^(.+).html$ https://%{HTTP_HOST}%{REQUEST_URI} [QSA,N] with RewriteRule ^(.+).html$ https://%{HTTP_HOST}/index.php?page=$1 [QSA,L] then the https redirection works fine but the fancy-url rewriting doesn't work. Is it possible to combine these two?
