    - Streaming Audio Recorder I am interested in writing a streaming audio recorder in C#, but I am not sure where to start. Are there libraries in .NET that would assist in capturing streaming audio and saving in various formats (MP3, WAV, etc) If this is possible, does the compact framework also support them Thanks in advance, Jody Tag: Visual C# General difference between dates Visual C#

    - Get sunrise and sunset time based on latitude and longitude Hi. I've tried my best to find a correct forum for where I can post about the location-specific/time question, but here goes: Home Automation software, like ActiveHome Pro and Insteon Timer Software (scroll down) have an ability to let me select a longitude/latitude (or city/state) based on sunrise and sunset time, so I wanted to implement this when developing my own home automation application. Once I know my longitude and latitude ( www.maporama.com is where I went there to find my longitude and latitude for my home address), how do I go about known when a sunrise and sunset occour at a certain time I do believe that home automation applications don't connect to the Internet to get the times for sunrise/sunset for every day, as it doesn't use the Internet...

    - My C# .net window app doesn't run on Core2Duo machine Hi all, I have a C# window app program that build on VS2005. It works fine on all P4 Window XP machines. I tried to run the same program on a Core2Duo Window XP machine and it won't run. Is it a known issue I heard if I re-compile my c# code on the Core2Duo machine (I don't have one), the problem should go away. Did anyone heard anything like this before Thanks in advanced Tag: Visual C# General difference between dates Visual C#

    - Best practice for global data Hi, I'm new to C# and newish to OOP. I'm a little confused about the best way of dealing with "global" data. For historical reasons my WinForms application doesn't use a database instead it uses a folder with various text and binary files in it. Some of these files are read-in at program startup and others are read on demand. At the moment I have an object called dataArchive that contains various collections of objects read from these data files. Ideally I'd like this dataArchive class to be accessible from every form without having to constantly be passing it around. So firstly what's the best way to achieve this. Secondly is this the right way to handle this situation, whenever I've searched for information most people seem to disapprove of having global data at all in OOP programs, so what is the proper alternative Thanks for any answers you can give me.

    - Challenge: Extract Highlighted text from window with focus in any app on desktop! When they first asked for this, I said it couldn't be done. Then they showed me an app that could do it. To simplify the discussion, lets say I want to perform a "special action" when a "special" key is pressed using the text that is highlighted in whatever window has focus, regardless of what the application is. Put another way, suppose I have Notepad running, and in the text that it is displaying I hightlight the word "Hello". Then I press something like <ctrl><f12> and my program, which is running but is not the application with focus, responds to the keystroke by performing a special action where the parameter is the word "hello". (As a silly example, lets say it generates a text file, puts "hello" in it, and saves it. ) Now - I've seen an app do this (something very similar)! It extracted selected text from a simple app I wrote - so there's no special Office Automation magic or something like that going on. The app that I saw do this isn't a dot net app, but hopefully it is still possible in dot net. My only idea is to somehow loop through all the windows on the desktop, find the one with focus, and then extract whatever text is currently highlighted. Zowie! Easy to say, right I also need to somehow capture the "special" keystroke no matter what application has focus. I need help with every step I've mentioned. ... or maybe there's a better way to approach it Help! Kirk Tag: Visual C# General difference between dates Visual C#

    - using Windows Authentication in ASP.NET 2.0 Hi, well...what actually i have done is that i have enabled windows authentication in my intranet web application. It works fine...when the user opens the site, a log-in pop-up appears. What i want to know is that whether i can store the login information in a cookie, session or somewhere so that the user, who has logged-in once in a day does'nt need to enter his user name/ password again and again. Is it even possible or not Thanks in advance Tag: Visual C# General difference between dates Visual C#

    - My C# application abruptly closes down on VS2005 Hello, I developed a simple C# application to download a file from a website. After testing it, I gave it to a customer to help him download patches etc.. from my company's update site. Surprisingly, when he clicks the download button on the form, the C# application closes . Sometimes, it even closes when puts his mouse cursor on any part of the C# form. This is very bizarre to me!!! My customer uses Windows 2000 Service Pack 4.0. He has the .NET runtime libraries installed on his PC. I have tried the application on XP, 2003 server and even on 2000 machines in my office and the application works just fine. I even tried this outside my company's network and it works. I just can't seem to understand what is happening I am trying to analyze this from every angle and I can't make any sense out of this!! Any ideas anyone Any anyone experiences this before Is this a machine specific problem Could this happen if one does not defragment their hard drives for a long time. Any help is appreciated.

    - Class Library Overhead Hi all, Say you have 2 libraries for the same thing. 1. Single dll for all methods, etc, like this: My.Array.Method1 My.Array.Method2 My.Math.Method1 My.Math.Method2 My.String.Method1 My.String.Method2 2. Have a seperate dll for each type, like Array, Math, String. Say I only need Math methods for a project, if I use #1 vs #2, would there be speed differences Since #1 is a larger library maybe there is an overhead of adding it, even though you don't use Array, String Or maybe the compiler only compiles or executes only what's called, so there is no performance difference between the two Thanks alot, Aw Tag: Visual C# General difference between dates Visual C#

    - Assigning lot's of string into an array after it has been declared I want to declare a class variable "plant" with 150 slots. I want to do this on a global( ) level in my class so I can use the variable anywhere. Then later in the code, in a method, I want to put 150 strings into these slots. I know I can do this by using: private string[] plant = new string [150]; and later: hand[0] = "ek"; hand[1] = "bok"; ... and so on. but is there any more convenient way I tried using: private string[] plant = new string [150]; and later plant[] = {"","","","",............} but that didn't work...

    - Is this really that hard?? All I want to do is re-get the value of a string every so often (say 5 mins).

    - Operator overload inheritance and casting. Hi ! I am new to C# so I often encounter some rather simple problems but I sometimes don't find a simple solution... Below is my simplified context (a Quaternion that inherits from a Vector4 object). My questions are : - why does the bold code throw an InvalidCastException From what I read, I understood that this parenthesis cast (isn't it called "implicit" cast ) may be used only to "unbox" an object, like the following Unboxing example Quaternion q1 = new Quaternion( 1, 2, 3, 4 ); Vector4 q2 = new Quaternion( 1, 0, 0, 0 ); q1 = ( Quaternion ) q2; // this works nicely So if I answered my own previous question, here is the second : - what would be a nice, clean, quick, ie efficient implementation so that I can perform What I want Quaternion q1 = new Quaternion( 1, 2, 3, 4 ); Quaternion unitQuaternion = q1 * ( 1 / q1.Norm ); I can use define an explicit cast (explicit operator from Vector4 to Quaternion in Vector4 class) but is seems ugly to me. I can also define a Quaternion constructor from a Vector4 object, and in both case use it in a redefinition of operator* in Quaternion class... But damn, a Quaternion IS a Vector4, there must be something nicer than that ! I appreciate any suggestion... THX ! Zitoun ... And here is The context #region Namespace Declarations using System; using System.Collections.Generic; using System.Text; #endregion Namespace Declarations namespace TestExamples { class Program { static void Main( string[] args ) { Quaternion q1 = new Quaternion( 1, 2, 3, 4 ); Quaternion q2 = ( Quaternion ) ( q1 * ( 1 / q1.Norm ) ) ; } } public class Vector4 { #region Fields protected double _w, _x, _y, _z; #endregion Fields #region Constructors public Vector4( double w, double x, double y, double z ) { _w = w; _x = x; _y = y; _z = z; } #endregion Constructors #region Properties public double w { get { return _w; } set { _w = value; } } public double x { get { return _x; } set { _x = value; } } public double y { get { return _y; } set { _y = value; } } public double z { get { return _z; } set { _z = value; } } public double Norm { get { return Math.Sqrt( w * w + x * x + y * y + z * z ); } } #endregion Properties #region Overloaded Operators public static Vector4 operator *( Vector4 v, double scalar ) { return new Vector4( v.w * scalar, v.x * scalar, v.y * scalar, v.z * scalar ); } #endregion Overloaded Operators } public class Quaternion : Vector4 { #region Constructor public Quaternion( double w, double x, double y, double z ) : base( w, x, y, z ) { } #endregion Constructor } } Tag: Visual C# General difference between dates Visual C#

    - Problem with Sockets Hi buddies, How are you !! I got the following problem while i am developing a chat software My software consists of two parts: Server Client each in a seperate project, and each works very well when they are working alone, but when i try to test my application -I run the server then the client- i got the problem that when the client create the TcpClient object i got this message: Only one usage of each socket address (protocol/network address/port) is normally permitted I think that is because i use the same port number for both applications but this is the only way to run both applications on the same machine. the short version of my question is: How can I start a TcpListener and a TcpClient on the same machine and the same port I tried all the windows registry things but no change accured, Thanks in advance.

    - Passing parameter as byref, readonly I remember from a couple of the C++ courses that I have taken that (in C++) you can pass a parameter by reference, but set it as readonly. I sort of remember it being ' const byref ' but I may be wrong - the concept is what is important. Doing this is supposed to improve performance because it only passes the pointer to the parameter, not the entire parameter. The readonly aspect, though, kept it safe from being inadvertantly changed by the method. The reason that I ask is that I am passing a couple of large objects in my c# program, and wondered there was something equivelant in c#. My suspicion is that the compiler takes care of it, but I wanted to be sure. Thanks, SteveJ Tag: Visual C# General difference between dates Visual C#

    - couple of questions arraylist I have been working in C# for a couple of weeks now so do tell me if im doing something incorrectly. i have setup a small program that uses three arraylists Build1,Build2,Build3 they all contain a objects i have named Part with data (string Name ,string type, double Cost, int Amount, double RelPerf) i can fill the arrays with parts using my GUI and remove parts w/o an issue what i need to do now is to create a new build. i need to filter each Build(1,2,3) for the lowest double value for Cost i.e search each build(1,2,3) for Part.type = a find which build contains the Part.type = a with the lowest value for Part.cost and add that part to a new ArrayList i then need to repeat this for Part.type b,c,d,e, etc i was considering using a foreach statement but im not entirely sure how to implement this any help would be greatly appreciated thanks Yakyb Tag: Visual C# General difference between dates Visual C#
