  • How Do I grep For non-ASCII Characters in UNIX

    - by Peter Conrey
    I have several very large XML files and I'm trying to find the lines that contain non-ASCII characters. I've tried the following: grep -e "[\x{00FF}-\x{FFFF}]" file.xml But this returns every line in the file, regardless of whether the line contains a character in the range specified. Do I have the syntax wrong or am I doing something else wrong? I've also tried: egrep "[\x{00FF}-\x{FFFF}]" file.xml (with both single and double quotes surrounding the pattern).

  • Boost.Test: Looking for a working non-Trivial Test Suite Example / Tutorial

    - by Robert S. Barnes
    The Boost.Test documentation and examples don't really seem to contain any non-trivial examples and so far the two tutorials I've found here and here while helpful are both fairly basic. I would like to have a master test suite for the entire project, while maintaining per module suites of unit tests and fixtures that can be run independently. I'll also be using a mock server to test various networking edge cases. I'm on Ubuntu 8.04, but I'll take any example Linux or Windows since I'm writing my own makefiles anyways.

  • jquery event listening, non-standard events

    - by Stacey
    I'm attempting to build a way for my selectors to 'listen' to 'global' events that are beyond the typical 'click' 'change' 'submit' etc. I've explored the various 'eventmanagers' that I could find, and they're all still designed for forms. Is there any way to do something like this for non-standard (i.e. custom) events? The goal is to have selectors subscribe to an event, and then be able to trigger it in one place and it will raise it for everything subscribed to it.

  • Non-SQL API for SQL Server?

    - by David Lively
    Is there any sort of non-SQL API for talking to SQL Server? I'm curious if there is a more direct way to retrieve table or view data. (I don't have a problem with SQL, just curious if any of the layer between the SQL parser and the underlying data store is exposed.)

  • WPF: Non focusable window

    - by StreamT
    I am developing WPF Touch Screen Keyboard. I need to know how is it possible to make main window non focusable, so other windows will be receiving the input when I click on virtual keyboard buttons. Simple applying "Focusable="False"" to the main window and all child controls doesn't work.

  • mod_rewrite browser trying to get content from non-existant dir

    - by humgl
    I have my mod_rewrite set up so that it redirects all requests that aren't targeting existing files or directories to index.php?req=* where * is the request. Works all fine but when I send the browser to something like this: http://myurl/A/B/C The browser tries to find all images, stylesheets in the non-existing folder C. How can I make the browser to look in / instead of the 'virtual' directory? Do I have to put an absolute path everywhere?

  • non contiguous String object C#.net

    - by Kazoom
    By what i understand String and StringBuilder objects both allocate contiguous memory underneath. My program runs for days buffering several output in a String object. This sometimes cause outofmemoryexception which i think is because of non availability of contiguous memory. my string size can go upto 100MBs and i m concatenating new string frequently this causes new string object being allocated. i can reduce new string object creation by using Stringbuilder but that would not solve my problem entirely Is there an alternative to a contiguous string object?

  • python: equivalent to Javascript "||" to override non-truthful value

    - by Jason S
    In Javascript I can do this: function A(x) { return x || 3; } This returns 3 if x is a "non-truthful" value like 0, null, false, and it returns x otherwise. This is useful for empty arguments, e.g. I can do A() and it will evaluate as 3. Does Python have an equivalent? I guess I could make one out of the ternary operator a if b else c but was wondering what people use for this.

  • MIN array function non zeros only

    - by user1717622
    I have been trying to get this array function to output (non-zero) minimum values in the 'FINAL DATA' AE column. Can you see a structural error in this formula? =IF($C$4="All EMEA", MIN(IF('FINAL DATA'!$2:$AE$250000<>0, ('FINAL DATA'!$J$2:$J$250000=$C$4)*('FINAL DATA'!$E$2:$E$250000=$E$4)*( 'FINAL DATA'!$AE$2:$AE$250000))), MIN(IF('FINAL DATA'!$AE$2:$AE$250000<>0, ('FINAL DATA'!$K$2:$K$250000=$C$4)*('FINAL DATA'!$E$2:$E$250000=$E$4)*( 'FINAL DATA'!$AE$2:$AE$250000))) )

  • Junit before class ( non static )

    - by Roman
    Are there any best practices to get Junit execute a function once in a test file , and it should also not be static. like @BeforeClass on non static function? Here is an ugly solution : @Before void init(){ if (init.get() == false){ init.set(true); // do once block } } well this is something i dont want to do , and i am looking for an integrated junit solution.

  • Hover only on non-transparent part of image

    - by Nirmal
    Is there any way to make only a non-transparent portion of an image to trigger mouse-over event? If the mouse travels to the transparent area, the mouse-out should be triggered and the script should listen for any mouse-over event on a layer underneath the image. Is it possible? Thanks for any input.

  • System loops using non-integers?

    - by mary
    I wrote a .sh file to compile and run a few programs for a homework assignment. I have a "for" loop in the script, but it won't work unless I use only integers: #!/bin/bash for (( i=10; i<=100000; i+=100)) do ./hw3_2_2 $i done The variable $i is an input for the program hw3_2_2, and I have non-integer values I'd like to use. How could I loop through running the code with a list of decimal numbers?

  • Detect non-closed connections to SQL

    - by JoeJoe
    I've inherited a very large project in ASP.net, SQL 2005 and have found where some SQL connections are not closed - which is bad. Without going thru every line of code, is there a way to detect if connections are not being closed? Performance counter? as a follow up - how does SQL reclaim unclosed connections. I'm using non-pooled connectionstring.

  • static thread function access non-static class member in C++

    - by user397390
    Class Test{ int value; static void* thread_func(void* args){ value++; } void newthread(){ pthread_create(&thread_func,...); } } I'm trying to create a thread in Class Test. Therefore compiler forces me to make thread_func static. However I cannot access the non-static member "value" anymore. It says: invalid use of member 'Class::value' in static member function Is there a way around it?

  • Inlining an array of non-default constructible objects in a C++ class

    - by porgarmingduod
    C++ doesn't allow a class containing an array of items that are not default constructible: class Gordian { public: int member; Gordian(int must_have_variable) : member(must_have_variable) {} }; class Knot { Gordian* pointer_array[8]; // Sure, this works. Gordian inlined_array[8]; // Won't compile. Can't be initialized. }; As even beginner C++ users know, the language guarantees that all members are initialized when constructing a class. And it doesn't trust the user to initialize everything in the constructor - one has to provide valid arguments to the constructors of all members before the body of the constructor even starts. Generally, that's a great idea as far as I'm concerned, but I've come across a situation where it would be a lot easier if I could actually have an array of non-default constructible objects. The obvious solution: Have an array of pointers to the objects. This is not optimal in my case, as I am using shared memory. It would force me to do extra allocation from an already contended resource (that is, the shared memory). The entire reason I want to have the array inlined in the object is to reduce the number of allocations. This is a situation where I would be willing to use a hack, even an ugly one, provided it works. One possible hack I am thinking about would be: class Knot { public: struct dummy { char padding[sizeof(Gordian)]; }; dummy inlined_array[8]; Gordian* get(int index) { return reinterpret_cast<Gordian*>(&inlined_array[index]); } Knot() { for (int x = 0; x != 8; x++) { new (get(x)) Gordian(x*x); } } }; Sure, it compiles, but I'm not exactly an experienced C++ programmer. That is, I couldn't possibly trust my hacks less. So, the questions: 1) Does the hack I came up with seem workable? What are the issues? (I'm mainly concerned with C++0x on newer versions of GCC). 2) Is there a better way to inline an array of non-default constructible objects in a class?

  • An object reference is required for the non-static field, method, or property using global variable

    - by Jose Cardama
    Hello Iam working in a global int in which a variable will be used later. I've made the global variable like this: class Foo { public static int stream = Bass.BASS_StreamCreateFile(path1.Text, 0, 0, BASSFlag.BASS_DEFAULT); } which will be later called like this: Foo.stream and it can also contain more then 1 stream for example stream20,30,etc... The problem here is that it returns me this error: "An object reference is required for the non-static field, method, or property" where I call the text in path1.Text How do I fix this?

  • Ruby Win32Api get single character non-blocking

    - by Markus Orreilly
    I'm trying to write a simple game working with two threads, one thread to get input from the user, and another thread to animate some scenes. I'm able to get characters without pressing ENTER just fine, but it blocks in the animating thread until the user presses a key. Does anyone know of a way to get a character from the keyboard non-blocking?

  • Can Django be used for non web apps?

    - by Leeks and Leaks
    I noticed in the main Django introductin they show a feature that maps python objects to the database. This doesn't strike me as being mutually exclusive with with development, is there any reason why this can't be used for non web apps? Is it easy to separate out?
