  • How can I invoke linux programs from C#/Mono?

    - by Thiado de Arruda
    I've been using MonoDevelop and Make to execute some build taks on a C project under linux, but I decided to abandon Make and switch to NAnt since I am more proficient in writing C# programs than Make/shell scripts, so I decided to write a custom NAnt task in C# to replace my Makefile. So, how can I invoke GCC or other shell commands from C#?

  • Migrating Magento Concern

    - by Pankaj Upadhyay
    We have a Magento 1.5.0.1 store running at a hosting provider. Now, we need to migrate the same from that server to a new hosting provider. I had talk with a technical guy from the new hosting provider who told me to do following things. Go into the cPanel Backup Wizard . Make a FULL BACKUP and download the zip file Then upload that zip file on their server in my root folder. Then tell them and they will do the restore. My Concern :- Will everything work as expected. What about the connectionstrings and database and all. Will database be automatically created and work the same. Also, somewhere I read that ver 1.5.0.1 used older type of database which might not work on new MySQLs. Can this too have any impact. Should i proceed in the same manner or I need to take care of some additional things to ensure smooth running.

  • Performance Cost of a Memcopy in C/C++

    - by Cenoc
    So whenever I write code I always think about the performance implications. I've often wondered, what is the "cost" of using a memcopy relative to other functions in terms of performance? For example, I may be writing a sequence of numbers to a static buffer and concentrate on a frame within the buffer, in order to keep the frame once I get to the end of the buffer, I might memcopy all of it to the beginning OR I can implement an algorithm to amortize the computation.

  • Array of function pointers in Java

    - by Waltzy
    I have read this question and I'm still not sure whether it is possible to keep pointers to methods in an array in Java, if anyone knows if this is possible or not it would be a real help. I'm trying to find an elegant solution of keeping a list of Strings and associated functions without writing a mess of hundreds of 'if's. Cheers edit- 'functions' changed to 'methods', seems to bug people.

  • Initializing a C++ vector to random values... fast

    - by Flamewires
    Hey, id like to make this as fast as possible because it gets called A LOT in a program i'm writing, so is there any faster way to initialize a C++ vector to random values than: double range;//set to the range of a particular function i want to evaluate. std::vector<double> x(30, 0.0); for (int i=0;i<x.size();i++) { x.at(i) = (rand()/(double)RAND_MAX)*range; } EDIT:Fixed x's initializer.

  • Get current Apache version string for display

    - by Stijn Sanders
    I'm writing an Apache module and want to get a string with the Apache name version and other details. Much like what gets added to outgoing headers, e.g.: Server: Apache/2.2.13 (Win32) I've tried code like this: apr_table_get(request_rec->headers_out,"Server") But that doesn't seem to work. Is there an API call I haven't found or am I doomed to get version resource data from httpd.exe?

  • Elegent way to collapse or expand sub-sequences of a list in Python?

    - by forgot
    I want to collapse or expand sub-sequences of a list e.g. ['A', 'B', 'D', 'E', 'H'] -> ['AB', 'DE', 'H'] and vice versa currently I wrote some ugly code like: while True: for i, x in enumerate(s): if x == 'A' and s[i+1] == 'B': s[i:i+2] = 'AB' break else: break For people who asking 'why do that thing': Actually I'm working on a optimizing compiler and this is the peephole part. Writing pattern matching is a little annoying.

  • SQL 2000 - Returning from a Stored Procedure

    - by user70192
    Hello, I'm writing a stored procedure. This procedure has a case where if it is met, I want to stop executing the procedure and return -1. How do I do this? Currently, I'm trying the following: IF @result <> 1 BEGIN SELECT -1 END However, SELECT is not a typical "return". As you can imagine I spend most of my time in code which is why i'm looking for something like a "return". Thank you,

  • Databases: Migrate data between MS Access DB and MYSQL

    - by Dean
    Hello, I have 2 databases, one is MS Access DB from an old website, and the other one is MYSQL from the new Joomla+VirtueMart based website. I need to migrate existing products from MS Access to MYSQL.

I there a better way and more efficient for that?

  • Are parametrized calls/sanitization/escaping characters necessary for hashed password fields in SQL queries?

    - by Computerish
    When writing a login system for a website, it is standard to use some combination of parameterized calls, sanitizing the user input, and/or escaping special characters to prevent SQL injection attacks. Any good login system, however, should also hash (and possibly salt) every password before it goes into an SQL query, so is it still necessary to worry about SQL injection attacks in passwords? Doesn't a hash completely eliminate any possibility of an SQL injection attack on its own?

  • Why does /**[newline] not always insert the Javadoc template including @param and @return in Eclipse

    - by Bas van den Broek
    I'm documenting code in Eclipse and have been using the /** followed by Enter alot to insert the Javadoc template. However this does not always work for some reason, it will create the template for writing comments but it won't automatically insert the @param and @return text. If I copy the exact same method to another class it will insert the full template. It would be a big help if anyone could tell me why it won't do this in some situations.

  • Response, Result, Reply, which is best?

    - by Robert Gould
    I'm refactoring some client-server code and it uses the terms Response, Result & Reply for the same thing (an answer from the server). And although its not really that important it's become hard to guess which word to use while writing new code, so I'd like to unify the three terms into one and do the appropriate refactoring, but I'm not sure which word is the "best", if there is such a thing. Any suggestions based on precedence and standards towards naming for this case?

  • Sorting a 2 dimensional array on multiple columns

    - by Anon
    I need to sort a 2 dimensional array of doubles on multiple columns using either C or C++. Could someone point me to the algorithm that I should use or an existing library (perhaps boost?) that has this functionality? I have a feeling that writing a recursive function may be the way to go but I am too lazy to write out the algorithm or implement it myself if it has been done elsewhere. :-) Thanks
