• How can I use a regular expression to match something in the form 'stuff=foo' 'stuff' = 'stuff' 'mor

  - by PherricOxide

  I need a regexp to match something like this, 'text' | 'text' | ... | 'text'(~text) = 'text' | 'text' | ... | 'text' I just want to divide it up into two sections, the part on the left of the equals sign and the part on the right. Any of the 'text' entries can have "=" between the ' characters though. I was thinking of trying to match an even number of 's followed by a =, but I'm not sure how to match an even number of something.. Also note I don't know how many entries on either side there could be. A couple examples, '51NL9637X33' | 'ISL6262ACRZ-T' | 'QFN'(~51NL9637X33) = '51NL9637X33' | 'ISL6262ACRZ-T' | 'INTERSIL' | 'QFN7SQ-HT1_P49' | '()' Should extract, '51NL9637X33' | 'ISL6262ACRZ-T' | 'QFN'(~51NL9637X33) and, '51NL9637X33' | 'ISL6262ACRZ-T' | 'INTERSIL' | 'QFN7SQ-HT1_P49' | '()' '227637' | 'SMTU2032_1' | 'SKT W/BAT'(~227637) = '227637' | 'SMTU2032_1' | 'RENATA' | 'SKT28_5X16_1-HT5_4_P2' | '()' :SPECIAL_A ='BAT_CR2032', PART_NUM_A='202649' Should extract, '227637' | 'SMTU2032_1' | 'SKT W/BAT'(~227637) and, '227637' | 'SMTU2032_1' | 'RENATA' | 'SKT28_5X16_1-HT5_4_P2' | '()' :SPECIAL_A ='BAT_CR2032', PART_NUM_A='202649' Also note the little tilda bit at the end of the first section is optional, so I can't just look for that.

• Beginner - C# iteration through directory to produce a file list

  - by dassouki

  The end goal is to have some form of a data structure that stores a hierarchal structure of a directory to be stored in a txt file. I'm using the following code and so far, and I'm struggling with combining dirs, subdirs, and files. /// <summary> /// code based on http://msdn.microsoft.com/en-us/library/bb513869.aspx /// </summary> /// <param name="strFolder"></param> public static void TraverseTree ( string strFolder ) { // Data structure to hold names of subfolders to be // examined for files. Stack<string> dirs = new Stack<string>( 20 ); if ( !System.IO.Directory.Exists( strFolder ) ) { throw new ArgumentException(); } dirs.Push( strFolder ); while ( dirs.Count > 0 ) { string currentDir = dirs.Pop(); string[] subDirs; try { subDirs = System.IO.Directory.GetDirectories( currentDir ); } catch ( UnauthorizedAccessException e ) { MessageBox.Show( "Error: " + e.Message ); continue; } catch ( System.IO.DirectoryNotFoundException e ) { MessageBox.Show( "Error: " + e.Message ); continue; } string[] files = null; try { files = System.IO.Directory.GetFiles( currentDir ); } catch ( UnauthorizedAccessException e ) { MessageBox.Show( "Error: " + e.Message ); continue; } catch ( System.IO.DirectoryNotFoundException e ) { MessageBox.Show( "Error: " + e.Message ); continue; } // Perform the required action on each file here. // Modify this block to perform your required task. /* foreach ( string file in files ) { try { // Perform whatever action is required in your scenario. System.IO.FileInfo fi = new System.IO.FileInfo( file ); Console.WriteLine( "{0}: {1}, {2}", fi.Name, fi.Length, fi.CreationTime ); } catch ( System.IO.FileNotFoundException e ) { // If file was deleted by a separate application // or thread since the call to TraverseTree() // then just continue. MessageBox.Show( "Error: " + e.Message ); continue; } } */ // Push the subdirectories onto the stack for traversal. // This could also be done before handing the files. foreach ( string str in subDirs ) dirs.Push( str ); foreach ( string str in files ) MessageBox.Show( str ); }

• Diff Algorithm

  - by Daniel Magliola

  I've been looking like crazy for an explanation of a diff algorithm that works and is efficient. The closest I got is this link to RFC 3284 (from several Eric Sink blog posts), which describes in perfectly understandable terms the data format in which the diff results are stored. However, it has no mention whatsoever as to how a program would reach these results while doing a diff. I'm trying to research this out of personal curiosity, because I'm sure there must be tradeoffs when implementing a diff algorithm, which are pretty clear sometimes when you look at diffs and wonder "why did the diff program chose this as a change instead of that?"... Does anyone know where I can find a description of an efficient algorithm that'd end up outputting VCDIFF? By the way, if you happen to find a description of the actual algorithm used by SourceGear's DiffMerge, that'd be even better. NOTE: longest common subsequence doesn't seem to be the algorithm used by VCDIFF, it looks like they're doing something smarter, given the data format they use. Thanks!

• Developing Android applications with Visual Studio 2008

  - by Goz

  Hi all, I've recently obtained an HTC Desire and I'm interested in porting my 3D engine to the device. I have a slight annoyance however. I'd love to be able to do development under Visual Studio 2008. Am I to assume I'm going to need to re-process my SLN files to do GCC builds? Its not a vast issue as I already have an application that processes SLN and VCProj files through GCC and then links them together at the other end. I'll just need to set up the right libraries with it. Are there any other gotchas I need to think about? Or, indeed, is there an easier way? Any info would be much appreciated! Cheers :)

• Silverlight 4 accessing WCF Data Services: BeginInvoke frustrations.

  - by Gatmando

  Hi, I'm attempting to follow a pattern for performing WCF data service queries using the Silverlight 4 beta. The following is my code: public CodeTables() { CodeCountries = new ObservableCollection<dsRealHomes.CodeCountries>(); dsRealHomes.RealHomesEntities myClient = null; myClient = staticGlobals.RealHomesContext(); object userState = null; myClient.BeginExecute<dsRealHomes.CodeCountries>(new Uri("CodeCountries"), (IAsyncResult asyncResult) => { Dispatcher.BeginInvoke( () => { var test = myClient.EndExecute<dsRealHomes.CodeCountries>asyncResult).ToList(); } ); }, userState); } This is derived from a number of examples I've come across for WCF data services with silverlight. Unfortunately no matter how I try to implement the code i end up with the following error on 'Dispatcher.BeginInvoke': 'An object reference is required for the non-static field, method, or property (System.Windows.Threading.Dispatcher.BeginInvoke(System.Action)' Thanks

• There is another way to load MSHTML documents without use Application.ProcessMessages?

  - by douglaslise

  There is another way to load MSHTML documents without use Application.ProcessMessages? To load a document into a IHTMLDocument I need to do this: while Doc.readyState <> 'complete' do Application.ProcessMessages; I want not to process all the message queue during the loading, because I would be changing my application flow, in other words, some messages that should be processed after the loading to be completed can be processed earlier, even before the loading end. There is a special message code that the IHTMLDocument expect to advance in the loading process? Or there is another way to load? Thanks.

• Javascript Regex to convert dot notation to bracket notation

  - by Tauren

  Consider this javascript: var joe = { name: "Joe Smith", location: { city: "Los Angeles", state: "California" } } var string = "{name} is currently in {location.city}, {location.state}"; var out = string.replace(/{([\w\.]+)}/g, function(wholematch,firstmatch) { return typeof values[firstmatch] !== 'undefined' ? values[firstmatch] : wholematch; }); This will output the following: Joe Smith is currently in {location.city}, {location.state} But I want to output the following: Joe Smith is currently in Los Angeles, California I'm looking for a good way to convert multiple levels of dot notation found between braces in the string into multiple parameters to be used with bracket notation, like this: values[first][second][third][etc] Essentially, for this example, I'm trying to figure out what regex string and function I would need to end up with the equivalent of: out = values[name] + " is currently in " + values["location"]["city"] + values["location"]["state"];

• loading multiple .mat files in MATLAB

  - by smilingbuddha

  I have 110 files named time1.mat, time2.mat ..., time110.mat. I want to load these matrices into the MATLAB workspace. I have always used load -'ASCII' matrix.mat to load an ASCII matrix file in the current folder. So I tried doing for i=1:10 filename=strcat('time',int2str(i),'.mat'); load -'ASCII' filename end But I am getting a MATLAB error as ??? Error using ==> load Unable to read file filename: No such file or directory. ? Of course the string filename seems to be evaluated correctly by MATLAB as time1.mat. in the first iteration where it crashes at the load line. Any suggestions how I should do this?

• iphone OCMockObject and unit-testing a class that inherits from NSURLConnection

  - by Justin Galzic

  I want to unit test the custom init method of a class that inherits from NSURLConnection -- how would I do this if the init of my testable class invokes NSURLConnection's initWithRequest? I'm using OCMock and normally, I can mock objects that are contained within my test class. For this inheritance scenario, what's the best approach to do this? - (void)testInit { id urlRequest = [OCMockObject mockForClass:[NSURLRequest class]]; MyURLConnectionWrapper *conn = [[MyURLConnectionWrapper alloc] initWithRequest:urlRequest delegate:self someData:extraneousData]; } My class is implemented like this: @interface MyURLConnectionWrapper : NSURLConnection { } - (id)initWithRequest:(NSURLRequest *)request delegate:(id)delegate someData:(NSString *)fooData @end @implementation MyURLConnectionWrapper - (id)initWithRequest:(NSURLRequest *)request delegate:(id)delegate someData:(NSString *)fooData { if (self = [super initWithRequest:request delegate:delegate]) { // do some additional work here } return self; } Here's the error I get: OCMockObject[NSURLRequest]: unexpected method invoked: _CFURLRequest

• Default Object being modified because of LINQ Query

  - by msarchet

  I'm doing the following code to filter a list of objects before it gets sent off to be printed. Dim printList As New List(Of dispillPatient) For Each pat As dispillPatient In patList If (From meds In pat.Medication Select meds Where meds.Print = True).Count > 0 Then Dim patAdd As New dispillPatient patAdd = pat patAdd.Medication = DirectCast((From meds In pat.Medication Select meds Where meds.Print = True).ToList, List(Of dispillMedication)) printList.Add(patAdd) End If Next What is happening is patList, which is my initial list, for every dispillPatient inside of it, that specific patients Medication object (which is another list), is being shorten to the list that is returned to the patAdd object. I think this has something to do with both the way that .NET makes the copy of my pat object when I do patAdd = pat and the LINQ query that I'm using. Has anyone had a similar issue before and\or what can I do to keep my initial list from getting truncated. Thanks

• Is there a way to make sure a background process spawned by my program is killed when my process ter

  - by Davy8

  Basically the child process runs indefinitely until killed in the background, and I want to clean it up when my program terminates for any reason, i.e. via the Taskmanager. Currently I have a while (Process.GetProcessesByName("ParentProcess").Count() 0) loop and exit if the parent process isn't running, but it seems pretty brittle, and if I wanted it to work under debugger in Visual Studio I'd have to add "ParentProcess.vshost" or something. Is there any way to make sure that the child process end without requiring the child process to know about the parent process? I'd prefer a solution in managed code, but if there isn't one I can PInvoke. Edit: Passing the PID seems like a more robust solution, but for curiosity's sake, what if the child process was not my code but some exe that I have no control over? Is there a way to safeguard against possibly creating orphaned child processes?

• Why does a multilanguage solution not work?

  - by Lukas

  My solution has a C# application project C# User Controls project C++ Mathematics project One of the UserControls uses function from the Mathematics (C++ project). This UserControl is used in the application. Building and starting the application works just fine. When typing the IntelliSense suggests all the contained classes and methods. The UserControl appears correctly, but on clicking a button which calls the C++ function I get a BadImageFormatException (it pops out on the end of the automatically created Main function). The help suggests to use /fixed:no for linking, but that is already set up.

• What is a good git server frontend for self hosted git repositories

  - by Ritesh M Nayak

  I am planning on deploying git for a project I am currently working on and was wondering if there are any free softwares that provide an easy to use web view of the git repository. I am primarily interested in using the front end to track changes, see diff information etc. There is a list of such front ends available here. Does anyone have any experience with any of these ? Which one would you suggest An open source clone of github would do just fine actually :D but I know thats too much to ask .

• How to keep my functions (objects/methods) 'lean and mean'

  - by Michel

  Hi, in all (Agile) articles i read about this: keep your code and functions small and easy to test. How should i do this with the 'controller' or 'coordinator' class? In my situation, i have to import data. In the end i have one object who coordinates this, and i was wondering if there is a way of keeping the coordinator lean(er) and mean(er). My coordinator now does the followling (pseudocode) //Write to the log that the import has started Log.StartImport() //Get the data in Excel sheet format result = new Downloader().GetExcelFile() //Log this step Log.LogStep(result ) //convert the data to intern objects result = new Converter().Convertdata(result); //Log this step Log.LogStep(result ) //write the data result = Repository.SaveData(result); //Log this step Log.LogStep(result ) Imho, this is one of those 'know all' classes or at least one being 'not lean and mean'? Or, am i taking this lean and mean thing to far and is it impossible to program an import without some kind of 'fat' importer/coordinator? Michel

• Ruby types of collections in ActiveRecord

  - by kmorris511

  If I have an object with a collection of child objects in ActiveRecord, i.e. class Foo < ActiveRecord::Base has_many :bars, ... end and I attempt to run Array's find method against that collection: foo_instance.bars.find { ... } I receive: ActiveRecord::RecordNotFound: Couldn't find Bar without an ID I assume this is because ActiveRecord has hijacked the find method for its own purposes. Now, I can use detect and everything is fine. However to satisfy my own curiousity, I attempted to use metaprogramming to explicitly steal the find method back for one run: unbound_method = [].method('find').unbind unbound_method.bind(foo_instance.bars).call { ... } and I receive this error: TypeError: bind argument must be an instance of Array so clearly Ruby doesn't think foo_instance.bars is an Array and yet: foo_instance.bars.instance_of?(Array) -> true Can anybody help me with an explanation of this and of a way to get around it with metaprogramming?

• MySQL Trigger creation

  - by Bruce Garlock

  I have an application where I need to INSERT an auto_increment value from a PK in another table. I know how to do this in PHP, but I need to have this done at the DB level, since I cannot change the program logic. I am new to triggers, so I'm sure this will be an easy answer for someone. Here is what I have so far: DELIMITER // CREATE TRIGGER new_project AFTER INSERT ON m_quality_header FOR EACH ROW BEGIN INSERT INTO m_quality_detail (d_matl_qa_ID) VALUES (NEW.h_matl_qa_ID); END// DELIMITER ; I just want the value of the auto_increment value from h_matl_qa_ID to be inserted as a new record into d_matl_qa_ID. The error I get is: "This version of MySQL doesn't yet support 'multiple triggers with the same action time and event for one table' But, I don't want to update the table that has the trigger, so why is my current code considered a 'multiple' trigger? This is on MySQL 5.0.45-7.el5 running on a CentOS 5 server (64-bit Intel) If I have to, I can modify the PHP code, but that needs to be the last resort.

• Editing Mac OS X login items in Objective-C through AppleScript

  - by mon4goos

  In my Cocoa program, I want to examine what programs are registered to run at startup and modify that list as I feel appropriate. In order to be compatible with Tiger it seems like I need to work through AppleScript. I currently have the following code: NSDictionary* errorDict; NSAppleEventDescriptor* returnDescriptor = NULL; NSString *appleSource = @"tell application \"System Events\"\n\ get every login item\n\ end tell"; NSAppleScript *appleScript = [[NSAppleScript alloc] initWithSource: appleSource]; returnDescriptor = [appleScript executeAndReturnError: &errorDict]; If I run that command in AppleScript, I get back an array of login items. However, I can't figure out how to iterate through this array in Objective-C. More specifically, I want to examine the names and paths of the programs registered to run at startup. Any ideas?

• Personal Project - Next practical language/tech to learn

  - by Paul Nathan

  I'm working on a personal project doing some finance analysis. It's a totally new field for me, and I'm really having fun with it so far, plus working in the high-level language arena is a great break from my embedded systems daytime work. I have a MySQL backend on a non-local server with a pile of stock data. My task now is to do some analysis of the stocks and produce something approximating a useful result. There are a couple technical difficulties. (1) I have a lot of records. To be precise, I believe I'm near 100K records right now, and this number grows by 6.1K each weekday. I need to create a way to rummage through these fields and do data analysis - based on a given computation, go look at this other set. Fine and dandy, nothing too outre. But this means I could really use a straightforward API for talking to MySQL. (2) Ideally, it runs on OS X 10.4.11. No Windows/Linux machine at home. (3) I can use PHP, C++, Perl, etc. I even have an R installation. I'm pretty flexible with stuff, so long as it runs on OS X. (Lots of options here, pick water, H20, or dihydrogen monoxide ;-) ) (4)Lack of hassle. While I like clever and fun ways of doing things, I'm trying to get some analysis done, not spend ten hours doing installation work and scratching my head figuring out a theoretical syntax question needed to spout out "hello world". What's the question? I'd like to dig into something different than my usual PHP/C++/C toolset. I'm looking for recommendations for languages/technologies that will assist me and meet the above requirements. In particular, I've heard a lot of buzz about F# and Python on SO. I've used CLISP for small problems before, and kinda liked it. I'm seeking opinions about those in particular. edit:since I rent the DB server and have a limited amount of CPU time online, I'm trying to do the analysis on a local machine.

• asp.net mvc log4postsharp

  - by mike

  Hi Iam trying to use log4post sharp for logging purposes, As far as Iam aware I have followed the instructions to get this up and running, I have not installed postsharp, rather I got the library files and midified my cs proj file to target those file, I have also tried installing postsharp on my machine. In either case I end up with this error Error 5 The plug-in "Log4PostSharp" required by the type "Log4PostSharp.LogAttribute" was not found. I have tried googling this and it seems there is no trace of this issue anywhere on the web. One difference between my implementation with other examples is that the postsharp dll that they use is PostSharp.public, mine is just PostSharp. I have tried searching for the former dll but cannot find it anywhere, the download only contains PostSharp.dll. I feel this may be the issue as I have followd all the insturctions to the letter to get this up and running. Any Ideas People?

• How Can I List a TDictionary in Alphabetical Order by Key in Delphi 2009?

  - by lkessler

  How can I use a TEnumerator to go through my TDictionary in sorted order by key? I've got something like this: var Dic: TDictionary<string, string>; begin Dic := TDictionary<string, string>.create; Dic.Add('Tired', 'I have been working on this too long'); Dic.Add('Early', 'It is too early in the morning to be working on this'); Dic.Add('HelpMe', 'I need some help'); Dic.Add('Dumb', 'Yes I know this example is dumb'); { The following is what I don't know how to do } for each string1 (ordered by string1) in Dic do some processing with the current Dic element Dic.Free; end; So I would like to process my dictionary in the order: Dumb, Early, HelpMe, Tired. Unfortunately the Delphi help is very minimal in describing how TEnumerator works and gives no examples that I can find. There is also very little written on the web about using Enumerators with Generics in Delphi.

• Mercurial Pull Error

  - by Tyler

  I am new to the dvcs world. My company uses perforce and I'm not a fan so I thought I'd try to use mercurial as a front end. I set it up on a windows machine with TortiseHG, enabled the Perfarce extension, did a small checkout (limiting the target revision) and pulled for the rest. This seemed to be more robust than clone alone. This seems to be working fairly well as I've been able to get up to change 8700 or so. My problem is with an error in the perforce repo. During the hg pull command it hits an error abort: file path/to/file.pl missing in p4 workspace and rolls back the transaction. Is there anyway to bypass or skip that file and force it to continue since this is not a file I care about.
