  • Building a regexp to split a string

    - by Kivin
    I'm seeking a solution to splitting a string which contains text in the following format: "abcd efgh 'ijklm no pqrs' tuv" which will produce the following results: ['abcd', 'efgh', 'ijklm no pqrs', 'tuv'] In otherwords, it splits by whitespace unless inside of a single quoted string. I think it could be done with .NET regexps using "Lookaround" operators, particularly balancing operators. I'm not so sure about perl.

  • WPF: Disable ListBox, but enable scrolling

    - by Matt Briggs
    Been banging my head against this all morning. Basically, I have a listbox, and I want to keep people from changing the selection during a long running process, but allow them to still scroll. Solution: All the answers were good, I went with swallowing mouse events since that was the most straight forward. I wired PreviewMouseDown and PreviewMouseUp to a single event, which checked my backgroundWorker.IsBusy, and if it was set the IsHandled property on the event args to true.

  • As-You-Type-Searching with Core Data / NSFetchedResultsController

    - by Snej
    I implemented an as-you-type-searching (text search on single attribute) by fetching with performFetch: after each given character by the user. The performFetch: is running in a background thread to avoid keyboard freezes. But while typing many useless fetches are started. A NSOperationQueue might be an option, but I wonder if there are other approaches for this quite usual search behavior. What's best practice to notice when fetching is done and the table view is updated with the previous fetch to start a new fetch?

  • How to update multiple rows with different values in mysql?

    - by user210481
    I have a table with a column 'A'. Some rows have 14 digits for the column 'A' and some have only 12. I need to transform all the entries to 14 digits. The datatype is varchar I would like to update all the rows at once (one query), adding zeros before the first digit, so an entry like 012345678910 would become 00012345678910. Is it possible to do it in one single query? Thanks

  • Tools to work with App Engine data dumps

    - by Thilo
    Using the bulkloader.py utility you can download all data from your application's Datastore. It is not obvious how the data is stored, however. From the looks of it, you get a SQLite file with all data in binary format in a single table: sqlite> .tables bulkloader_database_signature result sqlite> .schema result CREATE TABLE result ( id BLOB primary key, value BLOB not null, sort_key BLOB); Are there any tools to work with this data?

    If I had a N lists each of length M, how could I write a nice clean function to return a single list of length M, where each element is the sum of the corresponding elements in the N lists? (starting to learn lisp - go easy!)

  • How to force VS 2010 to skip "builds" of projects which haven't changed?

    - by Ladislav Mrnka
    Our product's solution has more than 100+ projects (500+ksloc of production code). Most of them are C# projects but we also have few using C++/CLI to bridge communication with native code. Rebuilding the whole solution takes several minutes. That's fine. If I want to rebuilt the solution I expect that it will really take some time. What is not fine is time needed to build solution after full rebuild. Imagine I used full rebuild and know without doing any changes to to the solution I press Build (F6 or Ctrl+Shift+B). Why it takes 35s if there was no change? In output I see that it started "building" of each project - it doesn't perform real build but it does something which consumes significant amount of time. That 35s delay is pain in the ass. Yes I can improve the time by not using build solution but only build project (Shift+F6). If I run build project on particular test project I'm currently working on it will take "only" 8+s. It requires me to run project build on correct project (the test project to ensure dependent tested code is build as well). At least ReSharper test runner correctly recognizes that only this single project must be build and rerunning test usually contains only 8+s compilation. My current coding Kata is: don't touch Ctrl+Shift+B. The test project build will take 8s even if I don't do any changes. The reason why it takes 8s is because it also "builds" dependencies = in my case it "builds" more than 20 projects but I made changes only to unit test or single dependency! I don't want it to touch other projects. Is there a way to simply tell VS to build only projects where some changes were done and projects which are dependent on changed ones (preferably this part as another build option)? I worry you will tell me that it is exactly what VS is doing but in MS way ... I want to improve my TDD experience and reduce the time of compilation (in TDD the compilation can happen twice per minute). To make this even more frustrated I'm working in a team where most of developers used to work on Java projects prior to joining this one. So you can imagine how they are pissed off when they must use VS in contrast to full incremental compilation in Java. I don't require incremental compilation of classes. I expect working incremental compilation of solutions. Especially in product like VS 2010 Ultimate which costs several thousands dollars. I really don't want to get answers like: Make a separate solution Unload projects you don't need etc. I can read those answers here. Those are not acceptable solutions. We're not paying for VS to do such compromises.

  • Dynamic FIFO queue

    - by sam
    Create a 4K buffer for storing 4 independent FIFO (first-in/first-out) queues of single byte character data. The organization of the FIFO should be as efficient as possible for storing the 4 queues to support dynamic (not fixed) queue size, insuring that no queue will overflow any other queue and given that it is unknown which queues may have the least # of elements and which queues may have the most # of elements.

  • Weirdest occurence ever, UIButton @selector detecting right button, doing wrong 'else_if'?

    - by Scott
    So I dynamically create 3 UIButtons (for now), with this loop: NSMutableArray *sites = [[NSMutableArray alloc] init]; NSString *one = @"Constution Center"; NSString *two = @"Franklin Court"; NSString *three = @"Presidents House"; [sites addObject: one]; [one release]; [sites addObject: two]; [two release]; [sites addObject: three]; [three release]; NSString *element; int j = 0; for (element in sites) { UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom]; //setframe (where on screen) //separation is 15px past the width (45-30) button.frame = CGRectMake(a, b + (j*45), c, d); [button setTitle:element forState:UIControlStateNormal]; button.backgroundColor = [SiteOneController myColor1]; [button addTarget:self action:@selector(showCCView:) forControlEvents:UIControlEventTouchUpInside]; [button setTag:j]; [self.view addSubview: button]; j++; } The @Selector method is here: - (void) showCCView:(id) sender { UIButton *button = (UIButton *)sender; int whichButton = button.tag; NSString* myNewString = [NSString stringWithFormat:@"%d", whichButton]; self.view = [[UIView alloc] initWithFrame:[[UIScreen mainScreen] applicationFrame]]; self.view.backgroundColor = [UIColor whiteColor]; UINavigationBar *cc = [SiteOneController myNavBar1:@"Constitution Center Content"]; UINavigationBar *fc = [SiteOneController myNavBar1:@"Franklin Court Content"]; UINavigationBar *ph = [SiteOneController myNavBar1:@"Presidents House Content"]; if (whichButton = 0) { NSLog(myNewString); [self.view addSubview:cc]; } else if (whichButton = 1) { NSLog(myNewString); [self.view addSubview:fc]; } else if (whichButton = 2) { NSLog(myNewString); [self.view addSubview:ph]; } } Now, it is printing the correct button tag to NSLog, as shown in the method, however EVERY SINGLE BUTTON is displaying a navigation bar with "Franklin Court" as the title, EVERY SINGLE ONE, even though when I click button 0, it says "Button 0 clicked" in the console, but still performs the else if (whichButton = 1) code. Am I missing something here?

  • How to create a dynamic width column in Twitter Bootstrap

    - by Elad
    How do you use Twitter Bootstrap to create a table-like list structure, where some columns take as much space as required to accommodate the widest element of that column, and a single column takes the remaining space? For example Id |Name |Email address 100001|Joe |[email protected] 100 |Christine|[email protected] 1001 |John |[email protected] the Id column takes just enough space to accommodate the 100001 id which is the longest id, and the Name column takes just enough space to accommodate the name Christine. The Email column takes the remaining space.

  • A continued saga of C# interoprability with unmanaged C++

    - by Gilad
    After a day of banging my head against the wall both literally and metaphorically, I plead for help: I have an unmanaged C++ project, which is compiled as a DLL. Let's call it CPP Project. It currently works in an unmanaged environment. In addition, I have created a WPF project, that shall be called WPF Project. This project is a simple and currently almost empty project. It contains a single window and I want it to use code from Project 1. For that, I have created a CLR C++ project, which shall be called Interop Project and is also compiled as a DLL. For simplicity I will attach some basic testing code I have boiled down to the basics. CPP Project has the following two testing files: tester.h #pragma once extern "C" class __declspec(dllexport) NativeTester { public: void NativeTest(); }; tester.cpp #include "tester.h" void NativeTester::NativeTest() { int i = 0; } Interop Project has the following file: InteropLib.h #pragma once #include <tester.h> using namespace System; namespace InteropLib { public ref class InteropProject { public: static void Test() { NativeTester nativeTester; nativeTester.NativeTest(); } }; } Lastly, WPF Project has a single window refrencing Interop Project: MainWindow.xaml.cs using System; using System.Windows; using InteropLib; namespace AppGUI { public partial class MainWindow : Window { public MainWindow() { InitializeComponent(); InteropProject.Test(); } } } And the XAML itself has an empty window (default created). Once I am trying to run the WPF project, I get the following error: System.Windows.Markup.XamlParseException: 'The invocation of the constructor on type 'AppGUI.MainWindow' that matches the specified binding constraints threw an exception.' Line number '3' and line position '9'. --- System.IO.FileNotFoundException: Could not load file or assembly 'InteropLib.dll' or one of its dependencies. The specified module could not be found. at AppGUI.MainWindow..ctor() Interestingly enough, if I do not export the class from CPP Project, I do not get this error. Say, if i change tester.h to: #pragma once class NativeTester { public: void NativeTest() { int i = 0; } }; However, in this case I cannot use my more complex classes. If I move my implementation to a cpp file like before, I get unresolved linkage errors due to my not exporting my code. The C++ code I want to actually use is large and has many classes and is object oriented, so I can't just move all my implementation to the h files. Please help me understand this horrific error I've been trying resolve without success. Thanks.

  • MSSQL 2008 FTS CONTAINSTABLE Not Returning More Than Five Rows

    - by Elijah Glover
    I have a single table called "Indexes", it contains one nvarchar and three ntext columns (all Full Text Indexes). Index is up to date. CONTAINSTABLE(Indexes, *), 'test', 5) //5 results No matter what I change the above keyword too, it only returns the first 3-5 results. It should roughly return 90-120 results, for the above query. SELECT count(*) FROM Indexes WHERE [Description] like '%test%' //122 results How would I start to troubleshoot this problem?

  • CSS Calendar Display

    - by Steven
    I created my own custom date picker consisting of an ASP TextBox, Button, and Calendar complete with CSS styles, javascript code, and event handling vb code. I want to use this date picker multiple times on my form. I know the wrong way to do this would be to copy all the code and just adjust each name accordingly. How can I put those controls, styles, and code into a single entity?

  • PDB: exception when in console - full stack trace

    - by EoghanM
    When at the pdb console, entering a statement which causes an exception results in just a single line stack trace, e.g. (Pdb) someFunc() *** TypeError: __init__() takes exactly 2 arguments (1 given) However I'd like to figure out where exactly in someFunc the error originates. i.e. in this case, which class __init__ is attached to. Is there a way to get a full stack trace in Pdb?
