• 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

• Sandboxed Javascript Execution in an Internet Explorer Extension (BHO)

  - by TelegramSam

  Firefox has the Sandbox and evalInSandbox(). Chrome has sandboxed execution in their content scripts (they call it isolated execution). I'm looking for the same thing in an IE browser extension. I can load a javascript file, then call evalScript(), but the code executes in the same environment as javascript that exists on the page. I need a way to run my library (which includes and is based on jQuery) in an sandboxed/isolated environment, but still allow it to modify the DOM as if it were running on the page. Jint looks promising, but cannot currently evaluate jQuery. (They can parse it.) How can I do this?

• Complex reporting on subversion (possibly Export Subversion log into database for reporting)

  - by James A. N. Stauffer

  What is the best way to do complex reporting on subversion logs like the following for each file? file, directory, last revision date, previous revision date(where revision date is at least 30 older than last), days diff(between revision dates) Since Subversion allows on revision to change multiple files I assume svn log needs to be run against each file individually. Ideas (that don't seem very good): Shell scripting to produce a csv file to be imported to a DB. The following is a start but doesn't show the filename: find . -name "." -print | xargs -l svn log -l 2 Shell scripting to produce XML and then use XSLT to create CSV to import to a DB. It might use a similar command to above but would still have some of the same limitation. Write a program to just parse the log on the whole directory tree, make one insert to DB per revision/file combination, and then query the DB.

• Python: split files using mutliple split delimiters

  - by donalmg

  Hi, I have multiple CSV files which I need to parse in a loop to gather information. The problem is that while they are the same format, some are delimited by '\t' and others by ','. After this, I want to remove the double-quote from around the string. Can python split via multiple possible delimiters? At the minute, I can split the line with one by using: f = open(filename, "r") fields = f.readlines() for fs in fields: sf = fs.split('\t') tf = [fi.strip ('"') for fi in sf] Any suggestions are welcome.

• UITableView backgroundColor always gray on iPad

  - by rjobidon

  Hi, When I set the backgroundColor for my UITableView it works fine on iPhone (device and simulator) but NOT on the iPad simulator. Instead I get a light gray background for any color I set including groupTableViewBackgroundColor. Steps to reproduce: Create a new navigation-based project. Open RootViewController.xib and set the table view style to "Grouped". Add this responder to the RootViewController:- (void)viewDidLoad { [super viewDidLoad]; self.view.backgroundColor = [UIColor blackColor]; } Select Simulator SDK 3.2, build and run. You will get a black background (device and simulator). Select your target in the project tree. Click on Project : Upgrade Current Target for iPad. Build and run. You will get a light gray background. Revert the table view style to Plain and you will get a black background. Thanks for your help!

• Google Reader API HTTP Response parsing (Objective C)

  - by JustinXXVII

  Using the API, trying to get items in a specific feed returns this: {“direction”:”ltr”,”id”:”feed/http://arstechnica.com/index.rssx”,”title”:”Ars Technica”,”description”:”The Art of Technology”,”self”:[{"href":"http://www.google.com/reader/api/0/stream/contents/feed/http://arstechnica.com/index.rssx?ot\u003d1273193172856169\u0026r\u003dn\u0026xt\u003duser/-/state/com.google/read\u0026n\u003d4\u0026ck\u003d1273193873\u0026client\u003diPadReader"}],”alternate”:[{"href":"http://arstechnica.com/index.php","type":"text/html"}],”updated”:1273193873,”items”:[]} They look like key/value pairs but it’s plain text with UTF8 String encoding and won’t encode into a dictionary.

What is your practice?

• How to retrieve all the records from a Berkeley DB in Ruby

  - by Federico Builes

  I'd like to be able to get all the key-values stored in a Berkeley DB using the Ruby bindings from http://github.com/mattbauer/bdb/tree/master but I'm not sure how to proceed. Any pointers will be appreciated. UPDATE Here's a small script that loops over the keys and prints them. Based on Pax' answer: require 'rubygems' require 'bdb' env = Bdb::Env.new(0) env.open('foo', Bdb::DB_CREATE,0) db = env.db db.open(nil, 'db1.db', nil, Bdb::Db::BTREE, Bdb::DB_CREATE,0) db.put(nil, 'key', 'value', 0) db.put(nil, 'key1', 'value1', 0) db.put(nil, 'key2', 'value2', 0) dbc = db.cursor(nil,0) key,val = dbc.get(nil,nil,Bdb::DB_FIRST) while key p key,val key,val = dbc.get(nil,nil,Bdb::DB_NEXT) end dbc.close db.close(0) env.close

• Better Flex memory profiling tools

  - by verveguy

  Does anyone know of any better tools that the Flex Builder Profiler? I've googled and googled to no avail. While the FB tools are OK for small apps / small leak situations, they're nowhere near adequate for wading through the thicket of object references that can arise in a large scale Flex app (that is leaking memory heavily). In particular, any reasonably complex view structure ends up with huge numbers of parent/child object references to the top level view - none of which are at all relevant to finding the one or two refs from outside the parent child subgraph that are causing the whole bolus to be non-GC'able. If no one has any better suggestions, I'm seriously considering writing a tool to parse the saved profile dumps that Flex Builder can generate so that I can do my own "graph pruning" to find the important refs. If I go this route, collaboration would be welcome!

• BOOST program_options: parsing multiple argument list.

  - by Arman

  Hello, I would like to pass the multiple arguments with positive or negative values. Is it possible to parse it? Currently I have a following initialization: vector<int> IDlist; namespace po = boost::program_options; po::options_description commands("Allowed options"); commands.add_options() ("IDlist",po::value< vector<int> >(&IDlist)->multitoken(), "Which IDs to trace: ex. --IDlist=0 1 200 -2") ("help","print help") ; and I would like to call: ./test_ids.x --IDlist=0 1 200 -2 unknown option -2 So,the program_options assumes that I am passing -2 as an another option. Can I configure the program_options in such a way that it can accept the negative integer values? Thanks Arman.

• How To Export to JNLP in Eclipse

  - by dimo414

  I watched today as someone painlessly exported a NetBeans java project to a JNLP file and HTML file that he could just copy to his web server. I, for whatever reason, have found making JNLPs someone challenging, and would love if I could do the same in Eclipse, but I can't seem to find such a function or a plugin which does this. The only thing I've found is this article but I can't really parse it, it's a bit dense to me, for instance it mentions: Ensure that the org.eclipse.equinox.launcher plug-in is in the feature or in one of the included feature; But if that's even a grammatical sentence, I don't know how to ensure what it says.

• java annotations: library to override annotations with xml files

  - by flybywire

  Java has annotations and that is good. However, some developers feel that it is best to annotate code with metadata using xml files - others prefer annotations but would use metadata to override annotations in source code. I am writing a Java framework that uses annotations. The question is: is there a standard way to define and parse metadata from xml files. I think this is something every framework that uses annotations could benefit from but I can seem to find something like this on the Internet. Must I roll my own xml parsing/validation or has someone already done something like this?

• JMeter to grab full querystring into a variable for future use

  - by jfbauer

  Someone provided me the regex to parse out a query string: (?<=\?)[^?]+$ I am trying to use that in JMeter with no luck (although I am successful in pulling out individual query string parameter values based on various example postings on the web). I created a regular expression extractor called "Grab QueryString". I selected the URL response field to check. For the reference name, I typed "myQueryString". For the regular expression, I entered your text. For template, I entered $1$ Match no = 1 Default Value = ERROR Unfortunately, "myQueryString" is getting populated with ERROR and not the URL query string as hoped when I try and use it as a parameter in a future GET. Thus, I see this in the "View Results Tree": https:/www.website.com/folder/page.aspx?ERROR Instead of: https:/www.website.com/folder/page.aspx?jfhjHSDjgdjhsjhsdhjSJHWed Did I do something wrong? Anyone have any suggestions?

• Comparing Dates in LINQ and C#

  - by Redburn

  I have a LINQ query which checks to see if there are any tests done since the beginning of the year. var MetersTestedCount = (from n in _mttDomainContext.MTTMeterTests where n.TestDate > DateTime.Parse("1/1/2010") select n.TestDate).Count(); This query however returns an empty set. I have a similar SQL query which pulls some records, USE MeterTestTracking Select * From MTTMeterTest WHERE TestDate > '1/1/2010' I have been to the previous posts. Even though similar, still no help: How to compare just the date, not the timestamp using LINQ and How to compare dates in LINQ? What's the correct way to check dates in LINQ to return a dataset?

• PHP form script error

• Text mining with PHP

  - by garyc40

  Hi, I'm doing a project for a college class I'm taking. I'm using PHP to build a simple web app that classify tweets as "positive" (or happy) and "negative" (or sad) based on a set of dictionaries. The algorithm I'm thinking of right now is Naive Bayes classifier or decision tree. However, I can't find any PHP library that helps me do some serious language processing. Python has NLTK (http://www.nltk.org). Is there anything like that for PHP? I'm planning to use WEKA as the back end of the web app (by calling Weka in command line from within PHP), but it doesn't seem that efficient. Do you have any idea what I should use for this project? Or should I just switch to Python? Thanks

• intercept RelativeSource FindAncestor

  - by Pradeep

  I have a WPF application which runs as a excel plugin, it has its visual tree like so Excel ElementHost WPF UserControl WPF ribbon bar control Now any controls sitting on the WPF ribbon bar control are not enabled when the plugin is loaded within excel. See error below System.Windows.Data Error: 4 : Cannot find source for binding with reference 'RelativeSource FindAncestor, AncestorType='System.Windows.Window', AncestorLevel='1''. BindingExpression:Path=IsActive; DataItem=null; target element is 'Ribbon' (Name=''); target property is 'NoTarget' (type 'Object') If I nest the ribbon bar control in a standalone Window(outside excel) it works fine. Is there a way to intercept the FindAncestor call for a Window and wire it to something else.? Note that I cannot change the above binding as it isn't my control.

• Using truncate table alongside Hibernate?

  - by Marcus

  Is it OK to truncate tables while at the same time using Hibernate to insert data? We parse a big XML file with many relationships into Hibernate POJO's and persist to the DB. We are now planning on purging existing data at certain points in time by truncating the tables. Is this OK? It seems to work fine. We don't use Hibernate's second level cache. One thing I did notice, which is fine, is that when inserting we generate primary keys using Hibernate's @GeneratedValue where Hibernate just uses a key value one greater than the highest value in the table - and even though we are truncating the tables, Hibernate remembers the prior value and uses prior value + 1 as opposed to starting over at 1. This is fine, just unexpected. Note that the reason we do truncate as opposed to calling delete() on the Hibernate POJO's is for speed. We have gazillions of rows of data, and truncate is just so much faster.

• How to Animate a Gradient on a Path to visualize data flow in WPF/WCF app

  - by John

  I have an interesting project where several "nodes" on a cnavas are connected via a Path similiar to a mindmap tree. The path is used to visualize the connection state between two nodes. Red means the nodes are disconnected, green means they're connected. The next step would be to illustrate data flow (from A to B or B to A) using that path and an animation. Basically I would want to start the animation with the data transfer and stop it when the transfer is complete. Does anyone know how this could be done in WPF?

• Antlr question: cannot get Antlr tool to compile simple file from ANTLRWorks

  - by Don Henton

  Here is the grammar file: grammar fred; test : 'fred'; Here is the batch file to launch the tool: SET JAVA_HOME=C:\Program Files\Java\jdk1.6.0_24 SET PATH=%PATH%;%JAVA_HOME%\bin SET ANTLR_HOME=c:/users/don/workspace/antlrAssign/lib/ java -cp %ANTLR_HOME%/antlr-3.3-complete.jar antlr.Tool fred.g Here's the result: ANTLR Parser Generator Version 2.7.7 (20060906) 1989-2005 fred.g:1:1: unexpected token: grammar error: Token stream error reading grammar(s): fred.g:3:19: expecting ''', found 'r' fred.g:1:1: rule grammar trapped: fred.g:1:1: unexpected token: grammar TokenStreamException: expecting ''', found 'r' Prior postings refer to "org.antlr.Tool" but the 3.3 jar has it located as above. The idea was to create a debug version of a tree parser, and according to the documentation, you have to use the command line tool. Has anyone seen this before? Am I nuts? It's two lines long and its dying on the first word in the file. Of course this compiles in antlrworks. Any help appreciated, I can't afford any more adjustments to my medications.

• 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!
