• Best Practice: Accessing radio button group

  - by seth

  Looking for the best, standards compliant, cross browser compatible, forwards compatible way to access a group of radio buttons in the DOM (this is closely related to my other most recent post...), without the use of any external libraries. <input type="radio" value="1" name="myRadios" />One<br /> <input type="radio" value="2" name="myRadios" />Two<br /> I've read conflicting information on getElementsByName(), which seems like the proper way to do this, but I'm unclear if this is a standards compliant, forwards compatible solution. Perhaps there is a better way?

• Set form action dynamically in https-area

  - by Beerweasle

  Hi, heres the problem explanation: Im on the domain https://www.example.com - theres an Order-Form with the Action https://www.example-otherdomain.com with an other SSL Certificate. On some conditions i set the form action to https://www.example.com so that it will be posted on our domain, but if the user uses a CreditCart it should get posted to https://www.example-otherdomain.com. So far so good. But in some rare conditions, users with CreditCards still posts their form to https://www.example.com. So my idea is: Is there some Same-Domain-Policy for Javascript/HTTPS to protect the user from phishing? It seems that to set the FormAction to the same domain works, but not to reset it to the external one (with JS). I cant reproduce this error, so im asking here if someone knows if theres such a problem. It doesnt matter which UserAgent the user has (there are post datas from FF, Chrome, Webkit, IE7/8) Thx!

• PHP REMOTE_ADDR and secure sessions

  - by Christopher McCann

  One of the ways I have used to make securer sessions in the past is to also record the clients IP address and user agent at the handshake. Each time the client moves a page and calls session_start() I also check that the IP address and user agent stored is still the same to prevent hiijacking. But if someone is connecting from say a company network then all the users will probably have the same external static IP address and they could also really easily be using the same user agent. Is there other metrics I can use which are local only to the physical machine? Thanks

• How to commit a non-subversioned file into a repository ?

  - by devdude

  The environment: SVN, Netbeans, Hudson SVN Project A: Builds a library file (foo.jar). The build file is under /dist, which is ignored for svn, the sourcecode is under svn control. SVN Project B: holds all library files. (other SVN projects get all their libraries from here via external svn) Question: I want to commit foo.jar from A into B. How to do that ? foo.jar cannot be added or committed because it is not under SVN control. Thanks for any hints ! (The question is independent from the IDE and CI Server)

• Haskell - mapping the odd placed values and the even placed values differently

  - by Abstract

  Hey guys, is there an easy way. To take a list of numbers, say 123456. Then multiply the odd placed by three and the even placed by 1. i.e. (1 * 3) + (2 * 1) + (3 * 3) + (4*1) + (5*3) + (6*1) i was thinking the map function somewhere along the lines. But i don't know how to map *3 to just the odd placed values. Oh and if you could give me the version not in prelude that would be great like the actual function or functions, as if its being imported from an external haskell file Thanks for the help

• Simple 2 way encryption for C#

  - by Matt Dawdy

  I'm looking for very simple encrypt and decrypt functionality for some data. It's not mission critical. I need something to keep honest people honest, but something a little stronger than ROT13 or Base64. I'd prefer something that is already included in the .Net framework 2.0 so I don't have to worry about any external dependencies. Pre-emptive EDIT: I really don't want to have to mess around with public/private keys, etc. I don't know much about encryption, but I do enough to know that anything I wrote would be less than worthless...in fact, I'd probably screw up the math and make it trivial to crack.

• How to display and change an icon inside a python Tk Frame

  - by codingJoe

  I have a python Tkinter Frame that displays several fields. I want to also add an red/yellow/green icon that will display the status of an external device. The icon is loaded from a file called ICON_LED_RED.ico. How do I display the icon in my frame? How do I change the icon at runtime? for example replace BitmapImage('RED.ico') with BitmapImage('GREEN.ico') class Application(Frame): def init(self, master=None): Frame.__init__(self, master) self.pack() self.createWidgets() def createWidgets(self): # ...other frame code.. works just fine. self.OKBTN = Button(self) self.OKBTN["text"] = "OK" self.OKBTN["fg"] = "red" self.OKBTN["command"] = self.ok_btn_func self.OKBTN.pack({"side": "left"}) # when I add the following the frame window is not visible # The process is locked up such that I have to do a kill -9 self.statusFrame = Frame(self, bd=2, relief=RIDGE) Label(self.statusFrame, text='Status:').pack(side=LEFT, padx=5) self.statIcon = BitmapImage('data/ICON_LED_RED.ico') Label (self.statusFrame, image=self.statIcon ).grid() self.statusFrame.pack(expand=1, fill=X, pady=10, padx=5)

• Implementation of a C pre-processor in Python or JavaScript?

  - by grrussel

  Is there a known implementation of the C pre-processor tool implemented either in Python or JavaScript? I am looking for a way to robustly pre-process C (and C like) source code and want to be able to process, for example, conditional compilation and macros without invoking an external CPP tool or native code library. Another potential use case is pre-processing within a web application, within the web browser. So far, I have found implementations in Java, Perl, and of course, C and C again. It may be plausible to use one of the C to JavaScript compilers now becoming available. The PLY (Python Lex and Yacc) tools include a cpp implemented in Python.

• Python library to detect if a file has changed between different runs?

  - by Stefano Borini

  Suppose I have a program A. I run it, and performs some operation starting from a file foo.txt. Now A terminates. New run of A. It checks if the file foo.txt has changed. If the file has changed, A runs its operation again, otherwise, it quits. Does a library function/external library for this exists ? Of course it can be implemented with an md5 + a file/db containing the md5. I want to prevent reinventing the wheel.

• Configuring 2 XBee Modules on OSX for wireless connection

  - by Annette

  I am trying find out how and with which program for OSX (10.5.8) I can configure serial ports? I am trying to establish a wireless connection between two Xbee´s (RF modules) and cannot figure out how to use ZTerm nor screen under Terminal. The setup I am using is: an Arduino+Xbeeshield+Xbee with external power supply, and an xbee on the xbee explorer connected to the Computer via USB. I am trying to gather information on this through various forums, but most of them cover the configuration issue for PC using X-CTU (which I tried with CrossOver but it doesn´t recognize ny of my ports). According to one source, using screen under Terminal should show me all my serial ports, particularly /dev/tty.KeySerial1 - but it doesn´t show, even though I´ve plugged in both my arduino+xbee shield and the xbee on the explorer.

• How can I read malformed XML (unencoded entities) with Perl?

  I'm trying to parse an XML file I get from an external source but am having problems because there are unencoded XML entities in the text nodes. Essentially, I'm asking the same question as this, but for Perl instead of PHP. <report> <company>A & W</company> <company>Some Other Company with a < in Inc.</company> </report>

• How do I clear a WebView's content before loading a page?

  - by Mark

  I have an embedded WebView in my Cocoa application in which I load an external web page. Each time the user clicks on a button, the view opens and shows the page. The problem is that the second time the user opens the WebView, the previous page is still visible. Instead I'd like to show a blank/empty page (together with a progress indicator). How can I clear a WebView before loading a new page? The closest solution I could find was to call this: [webView stringByEvaluatingJavaScriptFromString:@"document.open();document.close()"]; Is there a better way to do this? Thanks!

• A simple php form in Joomla?!

  - by Ben Fransen

  Hi all, Someone came to me and asked me if I could add a form to their Joomla page. I figured this should be easy since Joomla is widely used and such thing should be supported. I'm googling arround for 1,5h now, and I have given 4 formcreators a try but this is driving me crazy. The editors are all very complex for the simplest task I want. A simple form with: 5 text input; 1 radio selection criteria; the message a visitor sends. So I've given pretty much up upon formbuilders. Is there a simple way to include an external, self-built very easy php form, into the contactpage? I hope to hear from you... Greetings from Holland

• How can I make a workspace-folder level build script visible in the Eclipse Project Explorer?

  - by Chris

  I have a number of interdependent projects in an Eclipse workspace. Eclipse manages dependencies between them within the IDE but I'm starting work on a master build script that will sit in the folder about all the projects (the workspace folder). I haven't decided on if I will use Maven, Gradle or Ant/Ivy tet, but my question is, is there a way so that I can see a build script in the workspace folder in the Project/Package explorer? Currently it only shows me projects, but assuming I decide on an Ant build, I want to be able to see the main build.xml file in this window. I've played around with settings to no avail. Is it possible? If not, should I just set up an external run configuration instead?

• Redirecting a large number of URLs with htaccess or php header

  - by Peter

  I have undergone a major website overhaul and now have 5,000+ incoming links from search engines and external sites, bookmark services etc that lead to dead pages or 404 errors. A lot of the pages have corresponding "permalinks" or known replacement hierarchy/URL structure. I've started to list the main redirects with htaccess or physical files with simply a header location reidrect which is clearly not sustainable! What would be the best method to list all of the old link addresses and their corresponding new addresses with htaccess, php headers, mysql, sitemap file or is it better to have all broken links and wait for search engines etc to re-index my site? Are there any implications for having a large number of redirecting files for this temporary period until links are reset?

• Can I use WCF on Visual Studio 2005?

  - by Hemant

  I am about to start a project which consumes third party web services. Because of a legacy system, I am told that I can only use Visual Studio 2005/.NET 2.0. (Though I would have preferred Visual Studio 2008 on .NET 3.5) My understanding is that WCF was released with .NET 3.0. So is there any possibility to use WCF on Visual Studio 2005 by using just the WCF assemblies of .NET 3.0? I will then try to convince them that it is just like using external framework which doesn't disturb anything.

• Excel Add-in memory explosion

  - by tsinik

  I wrote a small .NET add in to excel 2007 that read data from external c++ api and display it inside an excel. The task manager shows that I'm having a memory leak (the memory usage is inflate linearly up to 250MB after whitch it throws an "Excel cannot complete this task with available resources error") but the problem disappears as soon as I minimize the excel window. The api uses delegates to return data and I update it into a dictionary. another thread is updating the excel from the dictionary every second. It is unlikely that the unmanaged code is responsible of the leak. Does anybody have an idea what can cause this? 10x!

• Simple wrapping of C code with cython

  - by Jose

  Hi, I have a number of C functions, and I would like to call them from python. cython seems to be the way to go, but I can't really find an example of how exactly this is done. My C function looks like this: void calculate_daily ( char *db_name, int grid_id, int year, double *dtmp, double *dtmn, double *dtmx, double *dprec, double *ddtr, double *dayl, double *dpet, double *dpar ) ; All I want to do is to specify the first three parameters (a string and two integers), and recover 8 numpy arrays (or python lists. All the double arrays have N elements). My code assumes that the pointers are pointing to an already allocated chunk of memory. Also, the produced C code ought to link to some external libraries.

• Application settings methods? c++

  - by flyout

  I am thinking about adding configurable settings to an application, and I think the easiest ways are an external file or win registry (its a win only app). Which way would be better? I was wondering, an user with not enough permissions may not be able to create/write the config file. And in the case of the registry, would todays antivirus allow me to add/edit/remove keys? Or they only monitor certain keys? Also, if someone knows a class/lib to manage config settings (in pure win32) in vc++ please post it.

• Is it possible to use JavaScript to submit an unnamed form from outside an iFrame?

  - by Scott

  I know that may sound silly, but I'm trying to submit a form on a page inside an iFrame, from the parent site. Here's an example of the form: <form action="/add_email" method="post"> <div class="field"> <label for="newEmailAddress" style="width: auto">Add new email address</label> <input type="text" id="newEmailAddress" name="email" value="null" class="text-field" /> <input type="hidden" name="__app_key" value="null"/> <input type="submit" value="Add address and send activation email"> </div> </form> As you can see, the Submit button, and the form itself both lack a proper name or id, this is not something I have control over. (It's on an external website.) Any suggestions?

• Web Scraper via Web Service API?

  - by 001

  How would I go about doing the following... I want to build a web service for my application to grab a piece of data from an external website, that requires the user to login.

Is there a library to perform the following functions? or what do I do? automate fill-in form, auto click Automate submit button check which URL the user has landed on, and redirect user to URL Grab data from label. EDIT: what im asking for is there a web service, library etc to make it easier to perform screen scrapping/automation functions???

• Creating TCP network errors for unit testing

  - by Robert S. Barnes

  I'd like to create various network errors during testing. I'm using the Berkely sockets API directly in C++ on Linux. I'm running a mock server in another thread from within Boost.Test which listens on localhost. For instance, I'd like to create a timeout during connect. So far I've tried not calling accept in my mock server and setting the backlog to 1, then making multiple connections, but all seem to successfully connect. I would think that if there wasn't room in the backlog queue I would at least get a connection refused error if not a timeout. I'd like to do this all programatically if possible, but I'd consider using something external like IPchains to intentionally drop certain packets to certain ports during testing, but I'd need to automate creating and removing rules so I could do it from within my Boost.Test unit tests. I suppose I could mock the various system calls involved, but I'd rather go through a real TCP stack if possible. Ideas?

• Crowdsourcing translation for mobile developers?

  - by superg

  I am developing applications for mobile phones with different operating systems (Android, Symbian, iPhone). Applications are sold internationally so they need to be translated to different languages in addition to english version. I assume most mobile developers do the translations using some paid external service each time. This approach does not look very cost-effective to me. Would it make sense to have a website where simple translations would be done using crowdsourcing (other developers)? Most strings in mobile applications are very simple and short, for example "OK, "Cancel", "Are you sure?", "Please enter your password". Also the same strings are used in hundreds of applications. Instead of paying for translating all strings, developers could save money by only buying their difficult application specific translations. Does anyone agree with this idea? I have seen many opensource projects doing the translations succesfully using volunteers.

• C++ MFC add combo box string item from a widget ID

  - by OzBarry

  I've added a combo box in the gui editor in MSVC 2010 pro in my MFC project. I have a list of strings I am grabbing from an external source and want to add them to my combo box. I've searched for a while, and every post seems to suggest I need to use the CComboBox class, however, I have no idea how to get the class variable from the resource ID of the combobox element in the gui editor. In summary, how do I add a string to my combo box, either using a macro (like CB_ADDSTRING(RESOURCE_ID, "my string");) or using CComboBOx (something like CComboBox::GetObject(RESOURCE_ID)->AddString("blah");). I do not do much win32 api/mfc programming, and just started fiddling around with it.
