  • Multiple delimiters using Regex.Split in C#

    - by Arthur Frankel
    Let's say you need to split a string by various delimiters including newline (/r, /n) and a few other 'special' character strings. For example: This is a sample %%% text &&& that I would like to split %%% into an array. I would like the following in the resulting string array (contents via index) [0]This is a sample [1]text [2]that I would [3]like to split [4]into an array. I would like to use C# Regex.Split() function. What is the regex expression to match on all of my delimiters? Thanks in advance

  • Tracking EXC_BAD_ACCESS on iPad

    - by Aleks
    I've been using this code to create my UIWindow UIMyWindow* win = [[UIMyWindow alloc] initWithFrame:[[UIScreen mainScreen] applicationFrame]]; UIMyWindow isn't anything special it just has a pointer to a C++ class that does some wrapping of ObjectiveC. Recently my application start crashing after adding some line of code that doesn't have to do anything with the error. The line of code that I added is just allocating a C++ object but the program execution never reaches this line. Interesting enough my code works in Release. My only guess is that I made some memory corruption on a completely different place. My questions are: What type of memory corruption that can be? And is there some good practices to track them down?

  • Too slow gwt develpment mode !

    - by Ehsan Khodarahmi
    I'm using eclipse galileo with latest GWT 2.0 version in development mode, but it runs really slow (i should wait about 1 minute to open one page, but after compilation, my application works very well when I run it using tomcat 5.5). My code is not too heavy & i guess there is an os-related or software inconsistency problem, because I'd this problem before, but when i reinstalled my windows vista sp2 (I formatted my windows drive & reinstalled it), my problem solved for just some days & then again it became to slow ! I didn't install any special software on my windows, so i really dont know why this problem occures ??? any suggestion ?

  • Perl : how to interrupt/resume loop by user hitting a key?

    - by Michael Mao
    Hi all: This is for debugging purpose. I've got a for loop that generates some output to Cygwin bash's CLI. I know that I can redirect outputs to text files and use Perl or even just a normal text editor to inspect the values printed out for a particular iteration, just feel that a bit painful. What I am now thinking is, to place a special subroutine inside the for loop, so that it would be "interrupted" at the beginning of each iteration, and Perl script should only resume to run after user/programmer hits a key(the Enter Key from keyboard?) In this way I can directly inspect the values printed out during each iteration. Is there a simple way to do this, without using additional libraries/CPAN ? Many thanks to the hints/suggestions in advance.

  • Is there any kind of standard for 8086 multiprocessing?

    - by Earlz
    Back when I made an 8086 emulator I noticed that there was the LOCK prefix intended for synchonization in a multiprocessor environment. Yet the only multitasking I know of for the x86 arch. involves use of the APIC which didn't come around until either the Pentiums or 486s. Was there any kind of standard for 8086 multitasking or was it done by some manufacturer specific extensions to the instruction set and/or special ports? By standard, I mean things like: How do you separate the 2 processors if they both use the same memory? This is impossible without some kind of way to make each processor execute a different piece of code. (or cause an interrupt on only one processor)

  • How do I handle TODO comments in VisualStudio 2010?

    - by Ivan
    I'd like Visual Studio to list all lines having "TODO: " in their beginning (usually after a comment sign which may vary depending on the file type) that can be found in any textual file in solution (may it be C#, VB, F#, T-SQL, ASPX, XAML or just TXT) in a special panel showing what's written in the line right to "TODO: ", project name (I use to contain many projects in one solution), file name, line number, code block name (like class and method) if possible. Do you know of such an extension or maybe VisualStudio has this feature built-in somewhere? For example NetBeans has a sort of out-of-the-box.

  • Using static mutex in a class

    - by Dmitry Yudakov
    I have a class that I can have many instances of. Inside it creates and initializes some members from a 3rd party library (that use some global variables) and is not thread-safe. I thought about using static boost::mutex, that would be locked in my class constructor and destructor. Thus creating and destroying instances among my threads would be safe for the 3rd party members. class MyClass { static boost::mutex mx; // 3rd party library members public: MyClass(); ~MyClass(); }; MyClass::MyClass() { boost::mutex::scoped_lock scoped_lock(mx); // create and init 3rd party library stuff } MyClass::~MyClass() { boost::mutex::scoped_lock scoped_lock(mx); // destroy 3rd party library stuff } I cannot link because I receive error: undefined reference to `MyClass::mx` Do I need some special initialization of such static member? Is the whole conception of static mutex wrong?

  • Referencing Excel Sheets with JET Driver Sheets Are Duplicated with Underscores

    - by MasterMax1313
    I'm referencing an excel document with the JET database driver, which was working just fine until one day the application failed. Upon further investigation I noticed that the tabs were duplicated in some instances (all tabs actually) - i.e. Tab1$ and Tab1$_. I've researched this issue and found that it is caused by the user applying a filter. Now the filters have been removed, no special formatting, frozen panes, or print formats, but still I have these tabs duplicated. Normally I'd code around this, but since we're in a code freeze I need to come up with an Excel based solution. I want to get rid of those crazy underscored tab names / reverences. I could probably run a program to clean up the file if necessary, to send it back to the users, but I want to explore Excel options first. Thoughts? I have Excel 2010, and access to any other version as well.

  • Unsigned versus signed numbers as indexes

    - by simendsjo
    Whats the rationale for using signed numbers as indexes in .Net? In Python, you can index from the end of an array by sending negative numbers, but this is not the case in .Net. It's not easy for .Net to add such a feature later as it could break other code perhaps using special rules (yeah, a bad idea, but I guess it happens) on indexing. Not that I have ever have needed to index arrays over 2,147,483,647 in size, but I really cannot understand why they choose signed numbers. Can it be because it's more normal to use signed numbers in code?

  • Indexing SET field

    - by Dienow
    I have two entities A and B. They are related with many to many relation. Entity A can be related up to 100 B entities. Entity B can be related up to 10000 A entities. I need quick way to select for example 30 A entities, that have relation with specified B entities, filtered and sorted by different attributes. Here how I see ideal solution: I put all information I know about A entities, including their relations with B entities into single row (Special table with SET field) then add all necessary indexes. The problem is that you can't use index while querying by SET field. What should I do? I can replace database with something different, if that'll help.

  • anyone know of a custom membership provider implementation that check password strength against in-b

    - by ronaldwidha
    I've got an Asp.net MVC app and before being able to go live, the IT have requested for us to comply with their password policy. The flexibility of AspnetSqlMembershipProvider doesn’t quite satisfy the requirement. The password strength and length rules are as follows: one lowercase one Uppercase one number and or special character 8 characters in length so far, aspnetsqlmembershipprovider is good... Not allowed to use: Dictionary words Names, real or fictional Plain language phrases Dates Telephone numbers Car registration numbers User IDs Postal codes Organization name Only the first 4 criteria are satisfied by the aspnetsqlmembershipprovider. Do you know of any third party products that offers this functionality (preferably in the form of a custom membership provider)?

  • Database design: Using hundred of fields for little values

    - by user964260
    I'm planning to develop a PHP Web App, it will mainly be used by registered users(sessions) While thinking about the DB design, I was contemplating that in order to give the best user experience possible there would be lots of options for the user to activate, deactivate, specify, etc. For example: - Options for each layout elements, dialog boxes, dashboard, grid, etc. - color, size, stay visible, invisible, don't ask again, show everytime, advanced mode, simple mode, etc. This would get like 100s of fields ranging from simple Yes/No or 1 to N values..., for each user. So, is it having a field for each of these options the way to go? or how do those CRMs or CMS or other Web Apps do it to store lots of 1-2 char long values? Do they group them on Text fields separated by a special char and then "explode" them as an array for runtime usage? thank you

  • Simple installer for Visual C# Express 2008

    - by espais
    I am looking for some general feedback here. I have a very simple application that I created in VC# Express 2008, with no special dependencies. Now, I am going to release it as open source, and am curious as to how I should deploy it. Do I need to create an installer package with any dll's? Should I just zip up the *.exe file with a README? Also, how should I go about handling the requirement for the .NET framework that a C# program needs?

  • Cache whole result set or based on user ?

    - by eugeneK
    In my web application i have statistics which shown for each user separately ie. posts made , posts made today , articles started by and so on... Each user has his own special statistics. What is more flexible and "right" to work with one huge DataTable in Cache with whole data from all users and then loop thought DataTable to find certain user data or to cache each user ie. cacheObj + userID... User can filter his own results by dates and types which is why i need flexible and reliable solution thanks...

  • MySQL: Changing order of auto-incremented primary keys?

    - by Tom
    Hi, I have a table with a auto-incremented primary key: user_id. For a currently theoretical reason, I might need to change a user_id to be something else than it was when originally created through auto-incrementation. This means there's a possibility that the keys will not be in incremental order anymore: PK: 1 2 3 952 // changed key 4 5 6 7 I'm wondering whether this will cause problems, and whether MySQL reads something special to the incremental order of the keys, given that they should have come to existence in incremental order (which persists even when some rows are deleted). Assuming there are no associated foreignkey issues, or that these are under control, is there a problem with "messing with" the order of MySQL's autoincremented keys? Thank you.

  • Screen scraping C application without using OCR or DOM?

    - by Mrgreen
    We have a legacy system that is essentially a glorified telnet interface. We cannot use an alternative telnet client program to connect to the system since there are special features built into the client software they have provided us. I want to be able to screen scrape from this program, however that's proving very difficult. I have tried using WindowSpy and Spy++ to check the window text and it comes up blank. It's a custom C program written by the vendor (they have even disabled selecting text). I'm really looking for a free option and something I may perhaps be able to use in conjuction with a scripting language. It seems the only ways to grab text is directly from the Windows GDI or from memory, but that seems a little extreme. Can anyone recommend any software/DLLs that might be able to accomplish this? I'd be extremely appreciative.

  • Does replacing statements by expressions using the C++ comma operator could allow more compiler opti

    - by Gabriel Cuvillier
    The C++ comma operator is used to chain individual expressions, yielding the value of the last executed expression as the result. For example the skeleton code (6 statements, 6 expressions): step1; step2; if (condition) step3; return step4; else return step5; May be rewritten to: (1 statement, 6 expressions) return step1, step2, condition? step3, step4 : step5; I noticed that it is not possible to perform step-by-step debugging of such code, as the expression chain seems to be executed as a whole. Does it means that the compiler is able to perform special optimizations which are not possible with the traditional statement approach (specially if the steps are const or inline)? Note: I'm not talking about the coding style merit of that way of expressing sequence of expressions! Just about the possible optimisations allowed by replacing statements by expressions.

  • How to get all the updates for a Second Life Object (prim) using LIBOMV

    - by sura
    Hi All, In Second Life, I have an avatar and a primitive object that are moving with changing velocity. I use the LIBOMV library to create a text client to Second Life. Using this LIBOMV text client, I am trying to record the update packets of that avatar and object that are being sent to my text client by the server. I get frequent update packets for the avatar as its velocity changes, but I do not get update packets for the object that frequently, although it has a changing velocity. I would like to know whether there is any special setting I should use in order to solve this problem. /Su

  • Cheap windows driver signing for 64 bit Windows 7

    - by kayahr
    I need to install the libusb-win32 driver on Windows 7 64 bit machines. This driver is open source so it is not digitally signed so I want to do this my self but I wonder if this can be done WITHOUT paying lot of money. Is it possible to use a certificate which is NOT signed by Verisign or GlobalSign? Maybe self-signed or by using StartSSL instead? And if yes, how do I do it? According to this howto I have to use a "cross-certificate" (And there are only six available on the Microsoft list and most of them are for CAs which are no longer active) I don't care if the user is confronted with a warning message. I can even accept if the user has to install a special CA certificate first. I only require that the driver runs without manually disabling the signature check on each windows startup.

  • How do I temporarily monkey with a global module constant?

    - by Daniel
    Greetings, I want to tinker with the global memcache object, and I found the following problems. Cache is a constant Cache is a module I only want to modify the behavior of Cache globally for a small section of code for a possible major performance gain. Since Cache is a module, I can't re-assign it, or encapsulate it. I Would Like To Do This: Deep in a controller method... code code code... old_cache = Cache Cache = MyCache.new code code code... Cache = old_cache code code code... However, since Cache is a constant I'm forbidden to change it. Threading is not an issue at the moment. :) Would it be "good manners" for me to just alias_method the special code I need just for a small section of code and then later unalias it again? That doesn't pass the smell test IMHO. Does anyone have any ideas? TIA, -daniel

How to resolve this problem? Thanks!

  • List of fundamental data structures - what am I missing?

    - by jboxer
    I've been studying my fundamental data structures a bunch recently, trying to make sure I've got them down cold. By "fundamental", I mean the real basic ones. Fancy ones like Red-Black Trees and Bloom Filters are clearly worth knowing, but they're usually either enhancements of fundamental ones (Red-Black Trees are binary search trees with special properties to keep them balanced) or they're only useful in very specific situations (Bloom Filters). So far, I'm "fluent" in the following data structures: Arrays Linked Lists Stacks/Queues Binary Search Trees Heaps/Priority Queues Hash Tables However, I feel like I'm missing something. Are there any fundamental ones that I'm forgetting about? EDIT: Added these after posting the question Strings (suggested by catchmeifyoutry) Sets (suggested by Peter) Graphs (suggested by Nick D and aJ) B-Trees (Suggested by tloach) I'm a little on-the-fence about whether these are too fancy or not, but I think they're different enough from the fundamental structures (and important enough) to be worth studying as fundamental.

  • Possible Performance Considerations using Linq to SQL Repositories

    - by Robert Harvey
    I have an ASP.NET MVC application that uses Linq to SQL repositories for all interactions with the database. To deal with data security, I do trimming to filter data to only those items to which the user has access. This occurs in several places: Data in list views Links in a menu bar A treeview on the left hand side containing links to content Role-based security A special security attribute, inheriting from AuthorizeAttribute, that implements content-based authorization on every controller method. Each of these places instantiates a repository, which opens a Linq to Sql DataContext and accesses the database. So, by my count, each request for a page access opens at least six separate Linq to SQL DataContexts. Should I be concerned about this from a performance perspective, and if so, what can be done to mitigate it?

  • Application built using VS2010 does not work in VS-Express2008 - C

    - by Jamie Keeling
    Hello, I have wrote an application that consists of two projects in a solution, each project contains only 1 .c source file. I was using Visual Studio 2010 Ultimate but due to the University only supporting 2008 I decided to create a blank solution and copy the source files into the new one. After creating a new solution in VS2008 express, creating two projects and re-creating and adding the source files to the projects I ran the application. For some reason only one part of the application does not work, I use CreateProcess() to execute "Project1.exe" from Project 2. This works fine under vs2010 but for some reason it's not working under VS2008 express, GetLastError() is showing an Error 2: File Not Found. This is an image showing the same code in both IDE's: I'm not using anything special and I've made sure that both solutions/projects are using .Net 3.5. I can't work out why it would work for one IDE and not the other. Any suggestions? Thanks!
