• Is Microsoft Workflow Foundation really used ?

  - by ereOn

  Today, I had a training on "Microsoft Workflow Foundation". While I think the idea is neat, I still see it as a Proof Of Concept and not as a real-life solution. Building an entire application without having to type a single line of code (or only a few of them) seems just wrong. Have you ever used this technology and if so, can it really fit to big company projects ? What drawbacks/advantages have you got using it ?

• c# 3.5 class List<int> class initialisation

  - by josephj1989

  I can initialize a List like new List{1,2,3,4,5}; However List does not have a constructor which accepts a single parameter. So I tried to run this through the debugger and it seems to be calling the Add method. So how does the compiler know which method to invoke to add each individual element. This may be a silly question but I am a bit confused. Thanks

• how many div's can you have before the dom slows and becomes unstable?

  - by Max Fraser

  I am developing a jQtouch app and each request done via ajax creates a new div in the document for the loaded content. Only a single div is shown at any one time. How many div's can I have before the app starts getting unresponsive and slow? Anyone have any ideas on this?

• Using functions and environments

  - by Eduardo Leoni

  Following the recent discussions here (e.g. 1, 2 ) I am now using environments in some of my code. My question is, how do I create functions that modify environments according to its arguments? For example: y <- new.env() with(y, x <- 1) f <- function(env,z) { with(env, x+z) } f(y,z=1) throws Error in eval(expr, envir, enclos) : object 'z' not found I am using environments to keep concurrently two sets of simulations apart (without refactoring my code, which I wrote for a single set of experiments).

  - by Jorge

  function FakeClass(){}; FakeClass.prototype.someMethod = function(){}; FakeClass.prototype.otherMethod = function(){ //need to call someMethod() here. } I need to call someMethod from otherMethod, but apparently it doesn't work. If i build it as a single function (not prototyped), i can call it, but calling a prototyped does not work. How can i do it as if i was treating the function just like a class method?

• How to store data which contains quotes in MySQL

  - by Nitz

  In one of my forms I use the rich text editor from Yahoo!. Now i want to store the data from that textarea in a MySQL database. The user can enter anything in that textarea, e.g. many double or single quotes. How can I store that data? Normally we store by adding that data in one variable and then put that in sql, but the quotes cause problems.

• Efficient SQL to count an occurrence in the latest X rows

  - by pulegium

  For example I have: create table a (i int); Assume there are 10k rows. I want to count 0's in the last 20 rows. Something like: select count(*) from (select i from a limit 20) where i = 0; Is that possible to make it more efficient? Like a single SQL statement or something? PS. DB is SQLite3 if that matters at all...

• What's the quickest way to dump & load a MySQL InnoDB database using mysqldump?

  - by Josh Schwartzman

  I would like to create a copy of a database with approximately 40 InnoDB tables and around 1.5GB of data with mysqldump and MySQL 5.1. What are the best parameters (ie: --single-transaction) that will result in the quickest dump and load of the data? As well, when loading the data into the second DB, is it quicker to: 1) pipe the results directly to the second MySQL server instance and use the --compress option or 2) load it from a text file (ie: mysql < my_sql_dump.sql)

• SQL CONNECTION best Practices

  - by george9170

  Currently there is discussion as to what are the pros and cons of having a single sql connection architecture. To elaborate what we are discussing is, at application creation open a sql connection and at application close or error closing the sql connection. And not creating another connection at all, but using just that one to talk with the DB. We are wondering what the community thinks.

• How to match a variable list of items separated by commas

  - by user261915

  I want to turn something like this CS 240, CS 246, ECE 222, ... (more or less); Software Engineering students only into ('CS 240', 'CS 246', 'ECE 222', 'ECE 220') in Python, code that matches a single course looks like >>> re.search('([A-Z]{2,5} \d{3})', 'SE 112').groups() ('SE 112',) I prefer a regular expression only method because I have a bunch of other alternate reg exps using '|' to combine them. However, a method with split is acceptable.

• .htaccess authentication from a php script to prevent a browser dialog box

  - by digitalbart

  Using php I authenticate a user, then behind the scenes,they are then again authenticated a second time with a single .htaccess username & password. This would be the same for all users, but I would not want them to have to enter a username and password again and they would now be allowed to enter the password protected directory. I prefer not to use http://username@password:somedomain.com. Any thoughts?

• Extending a Java Swing class in Clojure

  - by mikera

  I'm trying to extend a Java Swing component in Clojure, i.e. I want to extend a javax.swing.JComponent and add some custom methods implemented in pure Clojure in addition to all the standard inherited methods. I've tried using "proxy" which works great if I just want a single instance (in the same way as an anonymous inner class). However I'd really like a named class so that I can generate an arbitrary number of instances. What's the recommended way of doing this?

• Overinclusion of libraries C++

  - by wyatt

  I'm reading about how to put a makefile together, but no-one seems to mention what to do if your files require different sets of libraries, they all seem to use the same set of libraries for each file. Since it seems unlikely that every single file has the same libraries, I take it the list they use must amalgamate all of the libraries required across the project. I just wanted to know if there's any downside to including too many libraries, or if the compiler works out which ones are needed and ignores the rest? Thanks

  There is a single WCF connection using TCP. Two threads on the server write to this connection consecutively. Is it always guaranteed that the first message gets processed by the client first? According to my understanding it should be guaranteed.
