• Is there a way to extract the message from a JavaScript dialog in Chrome?

  - by Samuel

  I’ve been working on an extension for automating tests in Chrome, and I came across an obscure issue with JavaScript dialogs. The message shown in the dialog can’t be readily retrieved/copied. I’ve used the GetWindowText and InternalGetWindowText functions, but they only return the title of the dialog and the text from the buttons, not the actual message itself. I even looked at programs that extract text from forms, but no luck. So does anyone know of a way to retrieve the text from these JavaScript dialogs in Chrome?

• Extracting methods body from a class of Java Source Code

  - by Muhammad Asaduzzaman

  Hi, I want to extract method body from a Java Source Code. Suppose I have the following code: public class A{ public void print(){ System.out.println("Print This thing"); System.out.println("Print This thing"); System.out.println("Print This thing"); } } My objective is not to extract the method name (in this case print) but also the bode of the method(In this case the three print statement inside the print method). Can anyone suggest how can I do so? Is their any library available for doing so.

• Would my situation be an appropriate place to use the ' /i ' REGEX attribute?

  - by Solignis

  I am making a large catalogue of all of the possible OS names that can be supported by my particular version of VMWare. Originally I was writing them all as they stood in the VMX files but then I found a website that had them all listed, the problem is they are not properly cased to provide a "perfect" match, would this be the perfect time to use the regex attribute for case insensitivity? Also as a side question, would it be possibly extract the list of OSs from the website?. They look to be in a HTML formated chart. It would save me a lot of time having to type them all out.

• Dynamic Data Extract Tools

  - by Kevin McGovern

  I've been searching around for a few weeks now for a tool that either is fully built or a direction of something I could build for dynamically extracting data via a web interface. Basically, what I'm looking for is a way to give users a list of all available data objects from our database and then let them pick ones from the list they'd like to view and set parameters then export the results to an excel file. Right now we're doing it purely with SQL statements but we have hundreds of objects so as you might imagine, those statements are really complex and prone to errors. It would be great if there was a tool available to do this or if someone had an idea of an easy way to organize this. Any help would be greatly appreciated. We've looked at BI tools like QlikView and Tableau but that is probably overkill for what we're trying to do. The open-source BI tools we've looked at seemed really primitive in their functionality. The other thing we looked at was MSAS (our DB is SQL Server) but I'd prefer something that was more database-agnostic and lived on a web server instead of on the database.

• How do I extract lines from a file using their line number on unix?

  - by monkeyking

  Using sed or similar how would you extract lines from a file? If I wanted lines 1,5,1010,20503 from a file, how would I get these 4 lines? What if I have a fairly large number of lines I need to extract? If I had a file with 100 lines, each representing a line number that I wanted to extract from another file, how would I do that?

• [Bash] Save part of matching pattern to variable

  - by Ben

  I want to extract a substring matching a pattern and save it to a file. An example string: Apr 12 19:24:17 PC_NMG kernel: sd 11:0:0:0: [sdf] Attached SCSI removable disk I want to extract the part between the brackets, in this case []. I tried to do something like grep -e '[$subtext]' to save the text in the brackets to a variable. Of course it doesn't work, but I am looking for a way similar to this. It would be very elegant to include a variable in a regex like this. What can I do best? Thanks!

• I want to create an expression for querystrings, this stuff is hard!

  - by jkirkerx

  I want to extract some keywords out of a query string for a search application in asp.net. I decoded the url string first, so it's plain text I have this to start with, but I want to add a keyword group I'd like to trim off the stuff for pure words, but not sure if that's possible I also have a long list of possible query string value fields that I want to check against ?q= @q= ?qs= &qs=

• JavaScript - get detailed information about the browser

  - by iconiK

  Basically I'm looking for something to give me easy access to information like useragentstring.com, but in JS, without me parsing the user agent and looking for each possible bit of text. The object could be something like this: browser = UserAgent.Browser; // Chrome browserVer = UserAgent.BrowserVersion; // 5.0.342.9 os = UserAgent.OperatingSystem; // Windows NT osVer = UserAgent.OperatingSystemVersion; // 6.1 layoutEng = UserAgent.LayoutEngine; // WebKit layoutEngVer = UserAgent.LayoutEngineVersion; // 533.2 Does something similar to that exist or do I have to write one myself? Writing yet another user agent parser doesn't seem that easy with all those impersonations going back to the dark ages of the web. Specifically I'm looking for something that doesn't just split the user agent into parts and give them to me, because that's as useless as the user agent itself; instead it should parse the user agent and recognize the engine, browser, OS, etc. and return the concrete parts only, as in the example.

• Using WPFPerf to profile a WPF 4.0 application doesn't show me any information

  - by Adrian

  I am trying to use WPFPerf to profile a WPF 4.0 application (I have the latest WPFPerf that should work on WPF 4.0 aps). I start the tool Visual Profiler from WPFPerf, I start my aplication, but after that nothing happens and the element tree from the Visual Profiler is empty. No other error message is shown. Can anyone tell me what am I not doint right? As an additional information, when I try to analize my .exe assembly or any other assembly from my application, I get a BadFormatException saying that the assembly was build with a newer version of .NET. From the download page http://go.microsoft.com/fwlink/?LinkID=191420 I see that this version of WPFPerf should be ok for my app

• Storing information inside YAML

  - by yuval

  I looked through the YAML for ruby documentation and couldn't find an answer. I have a list of several employees. Each has a name, phone, and email as such: Employees: Name | Phone | Email john 111 [email protected] joe 123 [email protected] joan 321 [email protected] How would I write the above information in YAML to end up with the following ruby output? employees = [ {:name => 'john', :phone => '111', :email => '[email protected]'}, {:name => 'joe', :phone => '123', :email => '[email protected]'}, {:name => 'joan', :phone => '321', :email => '[email protected]'} ] This is how I parse the YAML file: APP_CONFIG = YAML.load_file("#{RAILS_ROOT}/config/config.yml") Thank you!

• Extracting glyph-path information from ttf files

  - by Anonymous Coward

  I'm trying to figure out a way to extract the information encoded in ttf files. namely: The char-to-glyph table and the individual glyph path data. Does anyone have a good reference explaining the ttf file structure, or some other solution? Keep in mind that I'm not interested in any libraries that can do it for me either (unless they are open source and I can see how they are doing it). The "master" goal is to implement it in Javascript. Thanks!

• How can I update information in an Android Activity from a background Service

  - by tmm

  Hello, I am trying to create a simple Android application that has a ActivityList of information, when the application starts, I plan to start a Service that will be constantly calculating the data (it will be changing) and I want the ActivityList to be in sync with the data that the service is calculating for the life of the app. How can I set up my Activity to be listening to the Service? Is this the best way to approach this problem? For example, if you imagine a list of stock prices - the data would be being changed regularly and need to be in sync with the (in my case) Service that is calculating/fetching the data constantly. Thanks in advance

• Storing and comparing biometric information

  - by Chathuranga Chandrasekara

  I am not sure whether this is the best place to post this. But this is strongly related with programming so decided to put this here. In general we use biometrics in computer applications say for authentication. Lets get 2 examples finger prints and facial recognition. In those cases how we keep the information for comparison. As an example we can't keep a image and process it every time. So what are the methodologies we use to store/determine the similarity in such cases? Are there any special algorithms that designed for that purposes.? (Ex : To return a approximately equal value for a finger print of a certain person every time)

• PHP Curl's Proxy feature causes no information to be returned

  - by Grant David Bachman

  I'm working on a PHP script right now which sends requests to our school's servers to get real-time information about class sizes for different courses. The script runs perfectly fine when I don't use a proxy, returning a string full of course numbers and available seats. However, I want to make this a service for the students, and I'm afraid that if I make too many requests my ip will get blocked. So I'm attempting to do this through a proxy, with no success. As soon as I add the CURLOPT_HTTPPROXYTUNNEL and CURLOPT_PROXY fields to my requests nothing gets returned. I'm not even sure how to troubleshoot it at this point since I'm not getting an error message of any kind. Does anyone know what's going on or how to at least troubleshoot it?

• Parse Complex WSDL Parameter Information in C#

  - by jaws

  I am attempting to parse WSDL, along the lines of the example given here. The author notes, in the comments, that the example is not capable of drilling down into complex data types. And in fact, when I run the example, it does not appear to even handle simple data types. I have poked around in System.Web.Services.Description.ServiceDescription class, which is used in the example, but cannot find any actual parameter or return type information at run-time. I gather that I may need to do some manual parsing of an xsd file? Both google and stackoverflow appear to lack a complete example of how to drill down into complex types programmatically, so... how should I do this?

• Display exception information and Debug.Print() messages in Immediate Window

  - by Timwi

  A friend of mine claims that calls to Debug.Print() as well as first-chance exception notifications appear in the Immediate Window for him. I found this surprising; for me they only appear in the Output Window. MSDN claims (here) that you can implicitly enable them in the Immediate Window by explicitly disabling them in the Output Window. But that doesn't work for me; the messages are not shown in either window if I disable this. The Immediate Window remains empty. How do I get the Immediate Window to display this information?

• best way to parse plain text file with a nested information structure

How can I solve this problem?

• getting detailed information about structured exceptions

  - by Martin

  My Visual C++ application is compiled with /EHA option, letting me catch structured exceptions (division by zero, access violation, etc). I then translate those exceptions to my own exception class using _set_se_translator(). My goal is to improve our logging of those types of exceptions. I can get the type of exception from the EXCEPTION_RECORD structure, and the exception address. I would like to be able to gather more information, like the source file/location where the exception is thrown, the call stack, etc. Is that possible? I do create an exception minidump on structured exceptions - is there a tool to automatically get the call stack from that?

• Requesting information from the user inside a GTK main loop

  - by Victor Stanciu

  Hello, I am learning Python by building a simple PyGTK application that fetches data from some SVN repositories, using pysvn. The pysvn Client has a callback you can specify that it calls when Subversion needs authentication information for a repository. When that happens, I would like to open a dialog to ask the user for the credentials. The problem is, it seems the callback is called inside the GTK main loop, so it's basically called on every tick. Is there a way to prevent this? Perhaps by opening the dialog in a new thread? But then how do I return the tuple with the user data to the callback so it can return it to the pysvn.Client?

• How can I load static configuration information

  - by Goro

  In my code, I use JavaScript for UI and PHP for back end. I also use PHP to store application settings and sometimes my UI code needs to access this information. My configuration file looks something like this (config.php): $resolution_x = 1920; $resolution_y = 1080; etc... When I need to access any of these settings form JavaScript, i simply use <?php echo ... ?> to substitute the value directly, but it just doesn't strike me as very robust. Are they any dangers of doing this that I am not aware of? Is there a better way of doing this? Thank you,
