  • How to use unicode inside an xpath string? (UnicodeEncodeError)

    - by Gj
    I'm using xpath in Selenium RC via the Python api. I need to click an a element who's text is "Submit »" Here's the error that I'm getting: In [18]: sel.click(u"xpath=//a[text()='Submit \xbb')]") ERROR: An unexpected error occurred while tokenizing input The following traceback may be corrupted or invalid The error message is: ('EOF in multi-line statement', (1121, 0)) --------------------------------------------------------------------------- Exception Traceback (most recent call last) /Users/me/<ipython console> in <module>() /Users/me/selenium.pyc in click(self, locator) 282 'locator' is an element locator 283 """ --> 284 self.do_command("click", [locator,]) 285 286 /Users/me/selenium.pyc in do_command(self, verb, args) 213 #print "Selenium Result: " + repr(data) + "\n\n" 214 if (not data.startswith('OK')): --> 215 raise Exception, data 216 return data 217 <type 'str'>: (<type 'exceptions.UnicodeEncodeError'>, UnicodeEncodeError('ascii', u"ERROR: Invalid xpath [2]: //a[text()='Submit \xbb')]", 45, 46, 'ordinal not in range(128)'))

  • ec2_bundle_vol fails with error LoadError

    - by Koran
    Hi, I am a newbie in amazon ec2 setup. I have now setup a machine to my taste - and I now want to bundle it.

  • Copying data across tabs

    - by Guillermo
    Hello, I got two different forms in two different tabs. One has data from our system and the other one is an interface of another, external, system in wich we need to copy data into (XML or API integration not an option here) The this is that, having open both forms - in two different tabs - i need a greasemonkey script or something similar that allows my to copy data from one form to the other (using the getValue method in Javascript). The problem right now is that I cannot figure out how to reference with a greasemonkey script one particular tab or window (to rad data from or write data to). Do you think it would be possible to do what I'm thinking to do? THANKS

  • In Django how display all of the values aftere the for loop is finished instead of displaying them one by one

    - by Igor
    Hello, In my django project in the view I call the last 6 values in the column and send them to the template. I then would like to pass into google charts api those 6 values and have a graph. At the moment for some reason I get 6 different graphs. {% for foodbag in foodbags %} <img src="http://chart.apis.google.com/chart?chxl=0:|0|1|2|3|4|5|6&chxr=2,0,0&chxs=0,1,676767,10.5,1,l,676767|2,676767,5.5,0,l,676767&chxt=x,y&chs=300x170&cht=bvg&chco=76A4FB&chd=t:{{foodbag.12}},0&chma=0,5|5,5&chdlp=t&chtt=Food+Bags"/> {% endfor %} I'm not sure how to replace string chd=t:{{foodbag.12}}, with the 6 values I am trying to extract from foodbags. I would really appreciate the help. Thank you

  • Designing Web Service Using Ruby on Rails - Mapping ActiveRecord Models

    - by michaeldelorenzo
    I've put together a RoR application and would now like to publish a RESTful web service for interacting with my application. I'm not sure where to go exactly, I don't want to simply expose my ActiveRecord models since there is some data on each model that isn't needed or shouldn't be exposed via an API like this. I also don't want to create a SOAP solution. My application is built using Rails 2.3.5 and I hope to move to Rails 3.0 soon after its released. I'm basically looking for a way to map my ActiveRecord models to "models" that would be exposed via the web service. Is ActiveResource the correct thing to use? What about ActionWebService?

  • What could make GetCursorPos return incorrect coordinates of {0,0} ?

    - by Dave Moore
    We are seeing bad behavior in an application when it runs on Server 2008 (not R2). This is a WinForms application, and Control.MousePosition is returning {0,0} no matter where the mouse is on the screen... Control.MousePosition just makes a P/Invoke call to Win32 api GetCursorPos(). There is a control in our library that calls SetWindowsHookEx to hook WH_CALLWNDPROCRET for our entire process. I'm suspicious of this code, but tracing statements show that we're getting in + out of that hook cleanly. What else should I be looking for? Thanks, Dave

  • lingpipe terms of service

    - by Ke
    hi, im reading the lingpipe terms of service here - Lingpipe tos Does this mean that if i use lingpipe and integrate it into some other software ive built myself I have to make the software ive built myself available as open source? is this normal with OS licences? im referring to this bit Whether you distribute the Software or not, if you distribute any computer program that is not the Software, but that (a) is distributed in connection with the Software or contains any part of the Software, (b) causes the Software to be copied or modified (i.e., ran, used, or executed), such as through an API call, or (c) uses any output of the Software, then you must distribute that other computer program under a license defined as a Free Software License by the Free Software Foundation or an Approved Open Source License by the Open Source Initiative. cheers ke

  • does PHP 5.3 change the way file_get_contents works?

    - by ceejayoz
    I'm having an odd issue with PHP's file_get_contents. In the past, file_get_contents on a remote file returns the text of that file regardless of the HTTP status code returned. If I hit an API and it sends back JSON error information with a status of 500, file_get_contents gives me that JSON (with no indication that an error code was encountered). I've just set up a Ubuntu 10.04 server, which is the first Ubuntu to have PHP 5.3. Instead of giving me the JSON, PHP throws a warning when a 500 error is present. As a result, I can't parse the JSON and give a nice error message. It's nice that PHP is noticing there's an error in the remote file, but I need the JSON even (especially!) if there's a 500 error. There doesn't appear to be any way to switch this off. Has anyone encountered this? Any tips?

Common programming mistakes for .NET developers to avoid? Common programming mistakes for Haskell developers to avoid? Common programming mistakes for Python developers to avoid? Common Programming Mistakes for Ruby Developers to Avoid Common programming mistakes for PHP developers to avoid? what are some common mistakes made by Scala developers, and how can we avoid them? Also, as the biggest group of new Scala developers come from Java, what specific pitfalls they have to be aware of? For example, one often cited problem Java programmers moving to Scala make is use a procedural approach when a functional one would be more suitable in Scala. What other mistakes e.g. in API design newcomers should try to avoid.

  • Verbose Listing of All Application Layers/Tiers?

    - by leeand00
    I've looked at a few sites now, and I'm still struggling to find a complete listing of all the possible layers/tiers you can have in an application. From back in college (1999) I remember the following: Presentation Layer (Views) Application Layer (Controllers) Business Logic Layer (API/Rules) Persistence Layer (Database/Object Persistence/Model) I'm not advocating that they all be used...especially when you consider that too many layers/tiers could lead to an increase in complexity...I just wondered what the complete list might look like... Based on a couple of blogs I've found several different answers...and Javascript and client side technologies seem to have leaked in adding more client-side layers according to one blog the client side tier might even consist of Behavior Layer (Javascript, Flash) Presentation Layer (CSS/Images) Note: I though the entire client side layer was the presentation layer Structure Layer (XHTML, HTML) I'm just trying to get an abstract idea of what all the possible layers might be, (even though some people call them different things)

  • BigDecimal precision not persisted with javax.persistence annotations

    - by dkaczynski
    I am using the javax.persistence API and Hibernate to create annotations and persist entities and their attributes in an Oracle 11g Express database. I have the following attribute in an entity: @Column(precision = 12, scale = 9) private BigDecimal weightedScore; The goal is to persist a decimal value with a maximum of 12 digits and a maximum of 9 of those digits to the right of the decimal place. After calculating the weightedScore, the result is 0.1234, but once I commit the entity with the Oracle database, the value displays as 0.12. I can see this by either by using an EntityManager object to query the entry or by viewing it directly in the Oracle Application Express (Apex) interface in a web browser. How should I annotate my BigDecimal attribute so that the precision is persisted correctly? Note: We use an in-memory HSQL database to run our unit tests, and it does not experience the issue with the lack of precision, with or without the @Column annotation.

  • HTML Upload Form will only upload files found in the directory of the PHP file.

    - by vette982
    I have an image uploader that uses the imgur.com API and jQuery's .ajax() function to upload images to their servers. However, if I browse for an image using the <input type="file"/> element of the form, it will only be successful in uploading an image if the image file is found in the same directory as the page.php file that the form is found in (shown below). How can I allow the form to upload images from any directory on my computer? page.php: <form action="page.php" method="post"> <input type="file" name="doc" id="doc" /><br/> <input type="image" src="go.gif" name="submit" id="submit" /> </form>

  • How do I actually use Authorization Services?

    - by abrahamvegh
    I've been searching and experimenting for nearly four hours now, so I'm gonna just ask straight up: How can I correctly use the Authorization Services API to show the user a system-level authorization window, the same one you see when you click a lock icon in System Preferences? From what I can tell, there is no way to do it using Cocoa if you want to do it programmatically, and if your goal is to call an executable that normally needs to be called via sudo (in my case, /usr/bin/pmset) you're up a creek without a paddle. I challenge you, I implore you: Please, enlighten me. Thank you. :)

  • Access Adobe InDesign files

    - by PeterMmm
    I need some directions for the following problem: I have a lot of InDesign files and i have to setup a process that will track if a certain paragraph or text block has changed between diferent versions of the file. If the text block has changed i want to extract that text block in a "portable" format (html, pdf, txt). Is there an Adobe product that would do that ? Is there any public API to access an InDesign file ? Is there the posibility to export InDesign to, say, html ?

  • server side Adobe AIR apps

    - by Robbie
    This might sound like a really stupid question, but is there anyway to run an Adobe AIR application in a headless server side mode on a non-UI server (i.e. Linux)? I'm trying to build server side bots to interact with an API (grapevinetalk.com) and I want to use existing code to do that without having to re-write all the data munging etc for a new application. The application I'm trying to port is essentially a jQuery based AIR desktop app that I want to reuse for server side interactions. I've tried Rhino with envjs.com, but am having some issues so am looking at alternatives. Thanks Robbie

  • documentBuilder: The process cannot access the file because it is being used by another process

    - by st mnmn
    I am using DocumentBuilder (of openXML api), to those who doesn't know the documentBuilder I'll give a short explanation: it has a function 'BuildDocument' which gets list of sources (each source contains wmldocument), and string of fileName to save to. public static void BuildDocument(List<Source> sources, string fileName) the purpose of this function is to build one word docx which contains all the sources. it merges some docs to one. at the end of its functionality it saves the doc using: File.WriteAllBytes(...) but when I run my project on the server I keep getting the error: "The process cannot access the file because it is being used by another process." few times it works ok. and in the visualStudio it also works without errors. what can be the problem?

  • shared library in C

    - by sasayins
    Hi, I am creating a shared library in C but don't know what is the correct implementation of the source codes. I want to create an API like for example, printHello, int printHello( char * text ); This printHello function will call another function: In source file, libprinthello.c, void printHello( char * text ) { printHi(); printf("%s", text); } Since this printHello function is the interface for the user or application: In header file libprinthello.h, extern void printHello( char * text); Then in the source file of the printHi function, printhi.c void printHi() { printf("Hi\n"); } Then my problem is, since printHello is the only function that I want to expose in the user, what implementation should I do in printHi function?

  • How do I convert PDF to HTML programmatically?

    - by SoaperGEM
    Are there any classes, COM objects, command line utilities, or anything else that I can make an API for that can convert a PDF to an HTML document? Obviously the conversion might be a little rough since PDFs can contain a lot more than HTML can describe. I found a utility called pdftohtml on Source Forge, but quite honestly it does a horrible job with the conversion. I don't care if the software is free or commercial, but is there anything out there at all that I can incorporate with my own software to do this sort of conversion at least decently? I know Google's developed their own method of doing this, since you can click "View as HTML" on a PDF attached to an email through Gmail, but I was hoping there was something out available to the public. Remember, PDF to HTML. I'm NOT worried about HTML to PDF.

  • SHAddToRecentDocs without a file?

    - by Chris Becke
    I was toying with an IRC client, integrating it with the windows 7 app bar. To get a "Frequent" or "Recent" items list one has to call SHAddToRecentDocs API. I want to add recent IRC channels visited to the Windows 7 Jumplist for the IRC application. Now, my problem is, IRC channels don't exist in the file system. And SHAddToRecentDocs seems to insist on getting some sort of file system object. Ive tried to work around it by creating a IShellItem pointing to my application, and giving it a command line to launch the channel. The shell is rebelling however, and thus far has not visibly added any of my "recent document" attempts to the Jumplist. Is there no way to do this without creating some kind of entirely unwanted filesystem object?

  • optional local variables in rails partial templates: how do I get out of the (defined? foo) mess?

    - by brahn
    I've been a bad kid and used the following syntax in my partial templates to set default values for local variables if a value wasn't explicitly defined in the :locals hash when rendering the partial -- <% foo = default_value unless (defined? foo) %> This seemed to work fine until recently, when (for no reason I could discern) non-passed variables started behaving as if they had been defined to nil (rather than undefined). As has been pointed by various helpful people on SO, http://api.rubyonrails.org/classes/ActionView/Base.html says not to use defined? foo and instead to use local_assigns.has_key? :foo I'm trying to amend my ways, but that means changing a lot of templates. Can/should I just charge ahead and make this change in all the templates? Is there any trickiness I need to watch for? How diligently do I need to test each one?

  • Select points on a map

    - by Dave Hanna
    I am just beginning design work on a problem that I'm sure has been solved before. In a web based application, I need to: a) present a map b) place a set of points (map-pins) on the map c) allow the user at his browser to draw a simple closed curve on the map with his mouse d) send the path of that curve back to the server e) on the server, select from the set of points those that are within the closed curve. What are the best API's to use for this problem? (I know I can and will do more research with Google, but I'm figuring there is probably someone who has done this that can give me some pointers to narrow my search space.) Thanks.

  • Are there any free .NET OCR libraries that will perform OCR on an application window directly?

    - by Kelsey
    I am looking for a free .NET OCR library that will be able to do OCR on a given application window or even a image in memory (I can take a snapshot of the application window myself). I have looked at tessnet2 and MODI but both require an image located on disk. I need to use OCR because the application I am trying to write a script for does some wacky stuff that cannot be read using windows API and I need to scrape data from the screen. I have tested both of tessnet2 and MODI and they both can read the text mostly but because this has to run in an enviroment that will not be able to write to disk, I need it to be able to read directly from the applciation window or some type of memory stream. I am thinking OCR is my only soution but there could be other methods that I am not thinking of. Suggestions?

  • When to use MVP in Windows Forms .net application?

    - by Janalopa
    I am familiar with MVC/MVP though my question is simple, I'm about to program a simple Instant Messaging software when the engine and communication part is an open API. so my software will have about 3 forms, a splash screen with login details, the options form and a main form with all the functionality like: Friends List, Send message, Received messages (tabbed), search user, etc. In UI perspective, its important for the GUI to be in 1 form in my application. So my question is, for the only complicated form that I'm going to have, is it necessary to implement an MVP design pattern or in this case its better to just go straight forward and put all the logic in 1 place? THANKS Janalopa!

  • Markup filter wanted for a public website

    - by sibidiba
    Developing a community site where everyone can post text, I'm looking for a markup filter: What is not part of the markup must be escaped (htmlspecialchars()) as it is. Should turn URL-s automatically into links Should support some form of basic markups (bold, image, url, pre, list) Should have a simple parser, that turns user input text into HTML Content on the site is public to everyone, XSS must not allowed to happen. What do you suggest? What markup language in the first place? BBCode? Wiki? Markdown? Are there any complete API-s with good examples? PHP is available on the server side. If there is a WYSIWYG-like texarea in addition (like here on SO) that would be a fantastic bonus!

  • Interface Design Problem: Storing Result of Transactions

    - by jboyd
    Requirements: multiple sources of input (social media content) into a system multiple destinations of output (social media api's) sources and destinations WILL be added some pseudo: IContentProvider contentProvider = context.getBean("contentProvider"); List<Content> toPost = contentProvider.getContent(); for (Content c : toPost) { SocialMediaPresence smPresence = socialMediaService.getSMPresenceBySomeId(c.getDestId()); smPresence.hasTwitter(); smPresence.hasFacebook(); //just to show what this is smPresence.postContent(c); //post content could fail for some SM platforms, but shoulnd't be lost forever } So now I run out of steam, I need to know what content has been successfully posted, and if it hasn't gone too all platforms, or if another platform were added in the future that content needs to go out for it as well (therefore my content provider will need to not only know if content has gone out, but for what platforms). I'm not looking for code, although sample/pseudo is fine... I'm looking for an approach to this problem that I can implement
