  • Erlang programming exercises

    - by valya
    I'm learning Erlang. I've moved from Haskell so I don't want to and have to learn functional programming. But Erlang is quite specific because of the microprocesses. So, can you give me some examples which will be simple to test and measure and use all the power of Erlang?

  • Bitwise Operations -- Arithmetic Operations..

    - by RBA
    Hi, Can you please explain the below lines, with some good examples. A left arithmetic shift by n is equivalent to multiplying by 2n (provided the value does not overflow), while a right arithmetic shift by n of a two's complement value is equivalent to dividing by 2n(2 to the power n) and rounding toward negative infinity. If the binary number is treated as ones' complement, then the same right-shift operation results in division by 2n and rounding toward zero. Thankx..

  • Easiest Java image processing solution

    - by Daniel Fath
    Here is the deal, in my Java project I have to make a composite document that combines both text and images; So I'm looking for a way to manipulate pictures (rotate, change size, that sort of thing). The API I'm looking for should be clear and easy to learn (preferably with some examples), it should cover the basic transformations I made above - rotate,change size, eventually crop.

  • Regex to exclude 1 word out of a regex code.

    - by Mech Software
    I need a regex expert to help out on this one. Examples I've found on here and the net I cant seem to get right. I'm using PHP and I have the following regex expression /([^a-zA-Z0-9])GC([A-Z0-9]+)/ This matches items like GCABCD GC123A, etc. What i need to do is EXCLUDE GCSTATS from this. So basically I want it to work just as it has, except, ignore GCSTATS in the regex.

I have seen examples where the contents of the dialog is declared in the dialog initiation script and then injected. but that is just to bulky for me, I want to be able to create my markup inside the DIV which I turn into a dialog. Anyone got a solution for me?

  • Is it possible to transcode audio in C# using DirectSound?

    - by Robert Davis
    I want to transcode a lot of audio from its source format to PCM without resampling or messing with the sample size. I figure if Windows Media Player can play the file and it doesn't use a legacy ACM codecs it must be using DirectSound to do so (this is on Windows XP and Windows Server 2k3). So is it possible to access DirectSound from C# and do so? I've tried searching the web but all the examples have been about playback which I have no interest in doing.

  • How to reliably retrieve tables and columns information stored in Torque Criteria object

    - by David Zhao
    Hi there, Is there a way to retrieve tables, including alias tables, and columns, including alias columns, from an Apache Torque Criteria object reliably? I understand that there is methods like: getSelectedColumns, getAsColumns(), getJoins(), etc., but for examples, getJoins() will just return a list of joined tables strings in free text, where one has to use regular expression to extract the needed joined table information out of it. Thanks in advance! David

  • Bang Notation and Dot Notation in VBA and MS-Access

    - by Nitrodist
    While perusing an application that I'm documenting, I've run across some examples of bang notation in accessing object properties/methods, etc. and in other places they use dot notation for what seems like the same purpose. Is there a difference or preference to using one or the other? Some simple googling only reveals limited information on the subject with some people actually using it in opposite cases. Perhaps there is a coding standards section from MS somewhere that indicates the method of madness?

  • Integrating Apache Shiro with ASP.NET MVC

    - by Garry Shutler
    I'm looking at using Apache Shiro as a central authentication service for all our applications over a variety of platforms. It's hinted at that it can integrate with a variety of platforms which would be ideal for my purposes but I cannot find any examples of how this is achieved from .NET (ASP.NET MVC specifically if it makes any difference). Does anyone know where I can find an example of how to do this?
