C# - Implement Your Own Sorting Algorithm?
Apr 29, 2011Forgive me if this is a silly question....but I think back to my Comp. Sci. classes and I distinctly remember learning/being quizzed on several sorting algorithms and the corresponding 'Big O' notation.
Outside of the classroom though, I've never actually written code to sort. When I get results from a database, I use 'Order By'. Otherwise, I use a collection class that implements a sort. I have implemented IComparable to allow sorting; but I've never gone beyond that.Was sorting always just an academic pursuit for those of us who don't implement languages/frameworks? Or is it just that modern languages running on modern hardware make it a trivial detail to worry about?
Finally, when I call .Sort on a List(Of String), for example, what sort algorithm is being used under the hood?

.net - .Net WebRequest.Create Decoding Encoded URI?
Apr 19, 2012I am writing some rest calls to the LinkedIn API using web request and have hit an encoding issue.The LinkedIn API takes requires an encoded URI as one of the parameters on the lookup i am trying to run.
We are calling the api through .Net's WebRequest.Create; and when we pass in the URI it decodes it and as a result we can't get the data from the call. Im trying to open a URI like this[URL]..Is there a mechanism in the webrequest class to stop it decoding the passed in URI; or a work around for this?

View 16 RepliesDecoding Function Doesn't Seem To Work.
Feb 6, 2009I'm using some functions which can be compared to encoding/decoding, but it's a really simple and basic application, not really an encoding function.The problem is, the decoding function doesn't seem to work.

View 14 RepliesError When Decoding A Creationdate On PDF File
Dec 6, 2010I'm getting the following error when decoding a creation date:A first chance exception of type 'System.ArgumentOutOfRangeException'occurred in mscorlib.dll Hour, Minute, and Second parameters describe an un-representable DateTime.
I'm doing pdfdate.decode(xdoc.info("creationdate"))
Here's the info from the PDF file:
/CreationDate (D:191010319150120)
/Producer (Acrobat Distiller Daemon 3.01 for Solaris 2.3 and later
(SPARC))
/Creator (tif_convert_2_ps())
/Title (/tardir/tiffs/a386689.tiff)
/ModDate (D:20010320070957)
The Modification date seems to be a valid date, but, the creation date looks kinda weird to me. More intriguing is that when I get the properties of this file using ADOBE Reader it shows a valid date for the creation date field.
The Decoding Technique Used In Audio Decoders?
Oct 31, 20111.Converting a wav file to mp3
2.Create a mp3 player by use of a decoder for playing this mp3 file.
I want some help from the best audio programmer who can explain me the decoding logic used to play the mp3 file(Programatically) I am aware of the bit patterns and the data chunks of mp3.I have the knowledge of the data chunks used in mp3 and wav files .I have also used winmm.dll file earlier to ascend into and descend out of the data chunks of wave files.But don't know how the bits are played in a player.Now I need to convert the wav file into mp3 format by use of some encoder program.I came to know about some lame encoder program but am unable to get how to start understanding it's code.
Buffer/Array - Safe Application That Contains 3 Threads - Data Acquisition And Decoding - Data Graphing - FFT And Filtering
Aug 26, 2009I am trying to write a thread safe application that contains 3 threads : -
1 - Data acquisition and decoding
2- Data graphing
3 - FFT and filtering
Thread 1 is collecting bytes from the serial port and converting them int integers (so taking two bytes) after is has captured 64 Bytes and converted into 32 integers, it then needs to pass the array to the graphing thread.
The graphing thread then plots the data and waits for more data.
Thread 3 also waits until thread one has collected 2023 integers and takes these and performs some FFT calculations (which take time).
My question is how do i share the arrays between the three threads without deadlocking the program? as the serial thread will be flying around reasonable fast (1000 bytes per second) so it will synclock onto the shared buffers for most of the time.
Originally i was going to use two synchronised queues, so when thread 1 has collected 32 bytes it queues the data into the graph queue, and once it has collected 2023 it queues the data into the FFT queue.
Then thread 2 and 3 can simple dequeue the data.
However using queues has the overhead of casting the data in and out, and as i know the data type i was planning on using two arrays :-
Dim GraphArray() as ushort
Dim FFTArray() as ushort
Then Thread 1 adds data to each thread, and thread 2 and 3 simple wait until the correct amount of data is available before removing the data. my question is there an array type that allows me to remove x amount of data from an array?
Because i cannot do this easily with the ararys defined as above (GraphArray, FFTArray), as i was planning on making them 1mByte and allowing thread 1 to fill them Knowing they should never overflow and then let thread 2 and 3 remove x amout of bytes at a time unless there is a better way of doing it
VS 2008 "Decoding" Text In RichTextBox Control?
Jul 13, 2010So, imagine I have a RichTextBox control and a few buttons to allow the user to change the font size, set/unset bold, italic etc, and perhaps change the colour. Not much more than that. Can I then - in code - loop through the contents of the RichTextBox and determine which words are in bold or red or whatever, and where paragraphs start and end?
View 9 RepliesLooking For An Algorithm In C#?
Apr 14, 2010I'll do my best to explain what the algorithm is supposed to do:There's a class 'Recipe'.ach Recipe can include other Recipes but cannot include itself or any other Recipe that includes it. So, a simple example is we have just two Recipes A & B.A,B,C(1) Recipe C Adds B(2) Recipe B Adds A(3) Recipe attempts to add C, but can't because of the relationship. C- B - A.

Apr 29, 2009I am using VB.NET and I am trying to come up with some algorithm or some pseudo-code, or some VB.NET code that will let me do the following (hopefully I can explain this well):I have 2 collection objects, Cob1 and Cob2. These collection objects store objects that implement an interface called ICob. ICob has 3 properties. A boolean IsSelected property, a property called Length, which returns a TimeSpan, and a Rating property, which is a short integer.
OK, now Cob1 has about 100 objects stored in the collection and Cob2 is an empty collection. What I want to do is select objects from Cob1 and copy them over to Cob2. I want the following rules obeyed when selecting the objects though:
