How to get the path of a file after publishing my game

- by NDraskovic

I made a "game" for a college project that reads data from .txt file at startup and draws some models according to the data in that file. This is the code I use using (StreamReader sr = new StreamReader(@"C:\Users\User\Desktop\Linije.txt")) { String linija; while ((linija = sr.ReadLine()) != null) { red = linija.Split(','); model = red[0]; x = red[1]; y = red[2]; z = red[3]; elementi.Add(Convert.ToInt32(model)); podatci.Add(new Vector3(Convert.ToSingle(x),Convert.ToSingle(y),Convert.ToSingle(z))); } } As you see, this code fills some variables that are then used to define the model that will be drawn and the coordinates where it will be drawn. The problem that I'm having is that I don't know how to distribute that file to other computers (obviously on another computer it would have another path)? Do you have some advices on how to do this? P.S I tried to put it in the Content and set the Build Action on None, and I can see the file in the content directory, but when I change it, nothing happens (the models don't change as they should)

FileReader f0 = new FileReader("123.html"); StringBuilder sb = new StringBuilder(); BufferedReader br = new BufferedReader(f0); while((temp1=br.readLine())!=null) { sb.append(temp1); } String para = sb.toString().replaceAll("<br>","\n"); String textonly = Jsoup.parse(para).text(); System.out.println(textonly); FileWriter f1=new FileWriter("123.txt"); char buf1[] = new char[textonly.length()]; textonly.getChars(0,textonly.length(),buf1,0); for(i=0;i<buf1.length;i++) { if(buf1[i]=='\n') f1.write("\r\n"); f1.write(buf1[i]); } I've this code but it is taking only one file at a time. I want to select multiple files. I've 2000 files and I've given them numbering name from 1 to 2000 as "1.html". So I want to give for loop like for(i=1;i<=2000;i++) and after executing separate txt file should be generated.

dpkg behaving strangely?

How I use RegExp in my Java program? [migrated]

- by MIH1406

I have the following string examples: 00001 1 12 123 00002 3 7 321 00003 99 23 332 00004 192 50 912 In a separate text file. Numbers are separated by tabs not spaces. I tried to read the file and print each line if it matches a given RegExp, but I could not find the suitable RegExp for these lines. private static void readFile() { String fileName = "processes.lst"; FileReader file = null; String result = ""; try { file = new FileReader(fileName); BufferedReader reader = new BufferedReader(file); String line = null; String regEx = "[0-9]\t[0-9]\t[0-9]\t[0-9]"; while((line = reader.readLine()) != null) { if(line.matches(regEx)) { result += "\n" + line; } } } catch(Exception e) { System.out.println(e.getMessage()); } finally { if(file != null) try { file.close(); } catch(Exception e) { System.out.println(e.getMessage()); } } System.out.println(result); } I ended up without any string being printed!!

Monitoring settings in a configsection of your app.config for changes

- by dotjosh

The usage:public static void Main() { using(var configSectionAdapter = new ConfigurationSectionAdapter<ACISSInstanceConfigSection>("MyConfigSectionName")) { configSectionAdapter.ConfigSectionChanged += () => { Console.WriteLine("File has changed! New setting is " + configSectionAdapter.ConfigSection.MyConfigSetting); }; Console.WriteLine("The initial setting is " + configSectionAdapter.ConfigSection.MyConfigSetting); Console.ReadLine(); } } The meat: public class ConfigurationSectionAdapter<T> : IDisposable where T : ConfigurationSection { private readonly string _configSectionName; private FileSystemWatcher _fileWatcher; public ConfigurationSectionAdapter(string configSectionName) { _configSectionName = configSectionName; StartFileWatcher(); } private void StartFileWatcher() { var configurationFileDirectory = new FileInfo(Configuration.FilePath).Directory; _fileWatcher = new FileSystemWatcher(configurationFileDirectory.FullName); _fileWatcher.Changed += FileWatcherOnChanged; _fileWatcher.EnableRaisingEvents = true; } private void FileWatcherOnChanged(object sender, FileSystemEventArgs args) { var changedFileIsConfigurationFile = string.Equals(args.FullPath, Configuration.FilePath, StringComparison.OrdinalIgnoreCase); if (!changedFileIsConfigurationFile) return; ClearCache(); OnConfigSectionChanged(); } private void ClearCache() { ConfigurationManager.RefreshSection(_configSectionName); } public T ConfigSection { get { return (T)Configuration.GetSection(_configSectionName); } } private System.Configuration.Configuration Configuration { get { return ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.None); } } public delegate void ConfigChangedHandler(); public event ConfigChangedHandler ConfigSectionChanged; protected void OnConfigSectionChanged() { if (ConfigSectionChanged != null) ConfigSectionChanged(); } public void Dispose() { _fileWatcher.Changed -= FileWatcherOnChanged; _fileWatcher.EnableRaisingEvents = false; _fileWatcher.Dispose(); } }

About shared (static) Members and its behavior

- by Allende

I just realized that I can access shared members from instances of classes (probably this is not correct, but compile and run), and also learn/discover that, I can modify shared members, then create a new instance and access the new value of the shared member. My question is, what happens to the shared members, when it comes back to the "default" value (class declaration), how dangerous is it do this ? is it totally bad ? is it valid in some cases ?. If you want to test my point here is the code (console project vb.net) that I used to test shared members, as you can see/compile/run, the shared member "x" of the class "Hello" has default value string "Default", but at runtime it changes it, and after creating a new object of that class, this object has the new value of the shared member. Module Module1 Public Class hello Public Shared x As String = "Default" Public Sub New() End Sub End Class Sub Main() Console.WriteLine("hello.x=" & hello.x) Dim obj As New hello() Console.WriteLine("obj.x=" & obj.x) obj.x = "Default shared memeber, modified in object" Console.WriteLine("obj.x=" & obj.x) hello.x = "Defaul shared member, modified in class" Console.WriteLine("hello.x=" & hello.x) Dim obj2 As New hello() Console.WriteLine("obj2.x=" & obj2.x) Console.ReadLine() End Sub End Module UPDATE: First at all, thanks to everyone, each answer give feedback, I suppose, by respect I should choose one as "the answer", I don't want to be offensive to anyone, so please don't take it so bad if I didn't choose you answer.

How can I use timer to stop another thread? [on hold]

- by Haoda Fu

How can we stop another thread based on a timer? I was trying to use timer to stop another thread. But I didn't got a success. To better illustrate my point and for your easy to understand the key issue. I made the following sample example. Your help is really appreciated using System; using System.Collections.Generic; using System.Text; using System.Threading; using System.Timers; namespace TestCodes { public static class Program { private static Thread nT = new Thread(PrintABC); private static System.Timers.Timer aTimer; public static void Main() { aTimer = new System.Timers.Timer(1000); aTimer.Elapsed += TimerCallback; aTimer.Interval = 1000; aTimer.Enabled = true; nT.Start(); Console.ReadLine(); } private static void TimerCallback(Object o, ElapsedEventArgs e) { nT.Join(); Console.WriteLine("Complete the PrintABC"); GC.Collect(); } private static void PrintABC() { for (int iter = 1; iter < 300; iter++) { Console.WriteLine(iter+"abc"); Console.ReadKey(); //Thread.Sleep(100); } } } }

Importing tab delimited file into array in Visual Basic 2013 [migrated]

- by JaceG

I am needing to import a tab delimited text file that has 11 columns and an unknown number of rows (always minimum 3 rows). I would like to import this text file as an array and be able to call data from it as needed, throughout my project. And then, to make things more difficult, I need to replace items in the array, and even add more rows to it as the project goes on (all at runtime). Hopefully someone can suggest code corrections or useful methods. I'm hoping to use something like the array style sMyStrings(3,2), which I believe would be the easiest way to control my data. Any help is gladly appreciated, and worthy of a slab of beer. Here's the coding I have so far: Imports System.IO Imports Microsoft.VisualBasic.FileIO Public Class Main Dim strReadLine As String Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load Dim sReader As IO.StreamReader = Nothing Dim sRawString As String = Nothing Dim sMyStrings() As String = Nothing Dim intCount As Integer = -1 Dim intFullLoop As Integer = 0 If IO.File.Exists("C:\MyProject\Hardware.txt") Then ' Make sure the file exists sReader = New IO.StreamReader("C:\MyProject\Hardware.txt") Else MsgBox("File doesn't exist.", MsgBoxStyle.Critical, "Error") End End If Do While sReader.Peek >= 0 ' Make sure you can read beyond the current position sRawString = sReader.ReadLine() ' Read the current line sMyStrings = sRawString.Split(New Char() {Chr(9)}) ' Separate values and store in a string array For Each s As String In sMyStrings ' Loop through the string array intCount = intCount + 1 ' Increment If TextBox1.Text <> "" Then TextBox1.Text = TextBox1.Text & vbCrLf ' Add line feed TextBox1.Text = TextBox1.Text & s ' Add line to debug textbox If intFullLoop > 14 And intCount > -1 And CBool((intCount - 0) / 11 Mod 0) Then cmbSelectHinge.Items.Add(sMyStrings(intCount)) End If Next intCount = -1 intFullLoop = intFullLoop + 1 Loop End Sub

How to determine the end of list has been reached?

- by Sweta Dwivedi

I'm trying to animate my object according to a set of recorded values from kinect skeleton stream by saving the (x,y,z) stream from the skeletal data into a list and then set my objects x and y position from the x,y of the list. However, once the list end has been reached it starts to animate again from the start. I don't want that - I just want the model position to keep going in the positive X direction. Is there any way I can check if end of the list has been reached and to just update the model position in x direction? Or is there any other way to continue moving my sprite once the points in the list are over... i dont want it to start animating all the way again.. protected override void Update(GameTime gameTime) { //position += spriteSpeed * (float)gameTime.ElapsedGameTime.TotalSeconds; //// TODO: Add your update logic here using (StreamReader r = new StreamReader(f)) { string line; Viewport view = graphics.GraphicsDevice.Viewport; int maxWidth = view.Width; int maxHeight = view.Height; while((line = r.ReadLine()) != null) { string[] temp = line.Split(','); int x = (int) Math.Floor(((float.Parse(temp[0]) * 0.5f) + 0.5f) * maxWidth); int y = (int) Math.Floor(((float.Parse(temp[1]) * -0.5f) + 0.5f) * maxHeight); motion_2.Add(new Point(x, y)); } } position.X = motion_2[i].X; position.Y = motion_2[i].Y; i++; a_butterfly_up.Update(gameTime); a_butterfly_side.Update(gameTime); G_vidPlayer.Play(mossV); base.Update(gameTime); }

Dynamic (C# 4.0) & Var in a nutshell.

- by mbcrump

A Var is static typed - the compiler and runtime know the type. This can be used to save some keystrokes. The following are identical. Code Snippet var mike = "var demo"; Console.WriteLine(mike.GetType()); //Returns System.String string mike2 = "string Demo"; Console.WriteLine(mike2.GetType()); //Returns System.String A dynamic behaves like an object, but with dynamic dispatch. The compiler doesn’t know anything about it at compile time. Code Snippet dynamic duo = "dynamic duo"; Console.WriteLine(duo.GetType()); //System.String //duo.BlowUp(); //A dynamic type does not know if this exist until run-time. Console.ReadLine(); To further illustrate this point, the dynamic type called “duo” calls a method that does not exist called BlowUp(). As you can see from the screenshot below, the compiler is reporting no errors even though BlowUp() does not exist. The program will compile fine. It will however throw a runtimebinder exception after it hits that line of code in runtime. Let’s try the same thing with a Var. This time, we get a compiler error that says BlowUp() does not exist. This program will not compile until we add a BlowUp() method. I hope this helps with your understand of the two. If not, then drop me a line and I’ll be glad to answer it.

Creating an update method in a different class

- by Sweta Dwivedi

I have created a class called 3D model which will animate my 3D model by changing the model position according to the values based in a .txt file through a list... Since i'm using a foreach loop to read the point values when it reaches the end of the file.. XNA throws an out of bounds exception .. (which is obvious) but if i add the same code in my Game.cs update(gameTime) method.. then i dont have this problem..Any idea how to make my 3D model update work same as the update in game.cs .. Here is the code for some idea: public void patterns(GameTime gameTime) { motion_z = new List<Point3D>(); if (pattern == 1) { f = "E:/Motion_Track-output/Output1.txt"; } if (pattern == 2) { f = "E:/Motion_Track-output/cruse.txt"; } // TODO: Add your update logic here using (StreamReader r = new StreamReader(f)) { string line; //Viewport view = graphics.GraphicsDevice.Viewport; int maxWidth = view.Width; int maxHeight = view.Height; while ((line = r.ReadLine()) != null) { string[] temp = line.Split(','); int x = (int)Math.Floor(((float.Parse(temp[0]) * 0.5f) + 0.5f) * maxWidth); int y = (int)Math.Floor(((float.Parse(temp[1]) * -0.5f) + 0.5f) * maxHeight); int z = (int)Math.Floor(((float.Parse(temp[2]) / 4 * 20000))); motion_z.Add(new Point3D(x, y, z)); } modelPosition.X = (float)(motion_z[i].X); modelPosition.Y = (float)(motion_z[i].Y); modelPosition.Z = (float)(motion_z[i].Z); i++; } //Console.WriteLine("modelposX:" + modelPosition.X + "," + "motionzX:" + motion_z[i].X); }

BoundingSpheres move when they should not

- by NDraskovic

I have a XNA 4.0 project in which I load a file that contains type and coordinates of items I need to draw to the screen. Also I need to check if one particular type (the only movable one) is passing in front or trough other items. This is the code I use to load the configuration: if (ks.IsKeyDown(Microsoft.Xna.Framework.Input.Keys.L)) { this.GraphicsDevice.Clear(Color.CornflowerBlue); Otvaranje.ShowDialog(); try { using (StreamReader sr = new StreamReader(Otvaranje.FileName)) { String linija; while ((linija = sr.ReadLine()) != null) { red = linija.Split(','); model = red[0]; x = red[1]; y = red[2]; z = red[3]; elementi.Add(Convert.ToInt32(model)); podatci.Add(new Vector3(Convert.ToSingle(x), Convert.ToSingle(y), Convert.ToSingle(z))); sfere.Add(new BoundingSphere(new Vector3(Convert.ToSingle(x), Convert.ToSingle(y), Convert.ToSingle(z)), 1f)); } } } catch (Exception ex) { Window.Title = ex.ToString(); } } The "Otvaranje" is an OpenFileDialog object, "elementi" is a List (determines the type of item that would be drawn), podatci is a List (determines the location where the items will be drawn) and sfere is a List. Now I solved the picking algorithm (checking for ray and bounding sphere intersection) and it works fine, but the collision detection does not. I noticed, while using picking, that BoundingSphere's move even though the objects that they correspond to do not. The movable object is drawn to the world1 Matrix, and the static objects are drawn into the world2 Matrix (world1 and world2 have the same values, I just separated them so that the static elements would not move when the movable one does). The problem is that when I move the item I want, all boundingSpheres move accordingly. How can I move only the boundingSphere that corresponds to that particular item, and leave the rest where they are?

Project Euler Problem 14

- by MarkPearl

The Problem The following iterative sequence is defined for the set of positive integers: n n/2 (n is even) n 3n + 1 (n is odd) Using the rule above and starting with 13, we generate the following sequence: 13 40 20 10 5 16 8 4 2 1 It can be seen that this sequence (starting at 13 and finishing at 1) contains 10 terms. Although it has not been proved yet (Collatz Problem), it is thought that all starting numbers finish at 1. Which starting number, under one million, produces the longest chain? NOTE: Once the chain starts the terms are allowed to go above one million. The Solution public static long NextResultOdd(long n) { return (3 * n) + 1; } public static long NextResultEven(long n) { return n / 2; } public static long TraverseSequence(long n) { long x = n; long count = 1; while (x > 1) { if (x % 2 == 0) x = NextResultEven(x); else x = NextResultOdd(x); count++; } return count; } static void Main(string[] args) { long largest = 0; long pos = 0; for (long i = 1000000; i > 1; i--) { long temp = TraverseSequence(i); if (temp > largest) { largest = temp; pos = i; } } Console.WriteLine("{0} - {1}", pos, largest); Console.ReadLine(); }

Binding BoundingSpheres to a world matrix in XNA

- by NDraskovic

I made a program that loads the locations of items on the scene from a file like this: using (StreamReader sr = new StreamReader(OpenFileDialog1.FileName)) { String line; while ((line = sr.ReadLine()) != null) { red = line.Split(','); model = row[0]; x = row[1]; y = row[2]; z = row[3]; elements.Add(Convert.ToInt32(model)); data.Add(new Vector3(Convert.ToSingle(x), Convert.ToSingle(y), Convert.ToSingle(z))); sfepheres.Add(new BoundingSphere(new Vector3(Convert.ToSingle(x), Convert.ToSingle(y), Convert.ToSingle(z)), 1f)); } I also have a list of BoundingSpheres (called spheres) that adds a new bounding sphere for each line from the file. In this program I have one item (a simple box) that moves (it has its world matrix called matrixBox), and other items are static entire time (there is a world matrix that holds those elements called simply world). The problem i that when I move the box, bounding spheres move with it. So how can I bind all BoundingSpheres (except the one corresponding to the box) to the static world matrix so that they stay in their place when the box moves?

How Do Computers Work? [closed]

- by Rob P.

This is almost embarrassing ask...I have a degree in Computer Science (and a second one in progress). I've worked as a full-time .NET Developer for nearly five years. I generally seem competent at what I do. But I Don't Know How Computers Work! Please, bare with me for a second. A quick Google of 'How a Computer Works' will yield lots and lots of results, but I struggled to find one that really answered what I'm looking for. I realize this is a huge, huge question, so really, if you can just give me some keywords or some direction. I know there are components....the power supply, the motherboard, ram, CPU, etc...and I get the 'general idea' of what they do. But I really don't understand how you go from a line of code like Console.Readline() in .NET (or Java or C++) and have it actually do stuff. Sure, I'm vaguely aware of MSIL (in the case of .NET), and that some magic happens with the JIT compiler and it turns into native code (I think). I'm told Java is similar, and C++ cuts out the middle step. I've done some mainframe assembly, it was a few years back now. I remember there were some instructions and some CPU registers, and I wrote code....and then some magic happened....and my program would work (or crash). From what I understand, an 'Emulator' would simulate what happens when you call an instruction and it would update the CPU registers; but what makes those instructions work the way they do? Does this turn into an Electronics question and not a 'Computer' question? I'm guessing there isn't any practical reason for me to understand this, but I feel like I should be able to. (Yes, this is what happens when you spend a day with a small child. It takes them about 10 minutes and five iterations of asking 'Why?' for you to realize how much you don't know)

Find possible variations of one item out of multiple baskets.

- by tugberk

I have three baskets of balls and each of them has 10 balls which have the following numbers: Basket 1: 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 Basket 2: 11, 12, 13, 14, 15, 16, 17, 18, 19, 20 Basket 3: 21, 22, 23, 24, 25, 26, 27, 28, 29, 30 What would be the possible variations If I were to pick one ball from each basket? I guess this is called as Probability in Mathematics but not sure. How would you write this code in C# (or any other programming language) to get the correct results? Edit: Based on @Kilian Foth's comment, here is the solution in C#: class Program { static void Main(string[] args) { IEnumerable<string> basket1 = new List<string> { "1", "2", "3", "4", "5", "6", "7", "8", "9", "10" }; IEnumerable<string> basket2 = new List<string> { "11", "12", "13", "14", "15", "16", "17", "18", "19", "20" }; IEnumerable<string> basket3 = new List<string> { "21", "22", "23", "24", "25", "26", "27", "28", "29", "30" }; foreach (var item1 in basket1) foreach (var item2 in basket2) foreach (var item3 in basket3) { Console.WriteLine("{0}, {1}, {2}", item1, item2, item3); } Console.ReadLine(); } }

The better way to ask for input?

- by Skippy

I am wondering which is the best way to go with java code. I need to create a class with simple prompts for input.. I have tried using both classes and cannot work out the particular benefits for each. Is this because I am still in the early stages of programming or are there situations that will occur as it becomes more complex?? import java.util.Scanner; public class myClass { Scanner stdin = new Scanner(System.in); public String getInput(String prompt) { System.out.print(prompt); return stdin.nextLine(); } ... or import java.io.*; public class myClass { public static void main(String[] args) throws IOException { BufferedReader stdin = new BufferedReader (new InputStreamReader (System.in)); System.out.print("Input something: "); String name = stdin.readLine(); I know these examples are showing different methods within these classes, but thought this might serve well for the discussion. I'm really not sure which site is the best to ask this on.

How to use Twitter4j With JSF2 for Login? [on hold]

- by subodh

I am trying to do login with Twitter and using Twitter4j for that and wrote this code In JSF <h:commandButton id="twitterbutton" value="Sign up with Twitter" action="#{twitterLoginBean.redirectTwitterLogin}" immediate="true" styleClass="twitterbutton"/> In ManagedBean public String redirectTwitterLogin() throws ServletException, IOException, TwitterException { HttpServletRequest request = (HttpServletRequest) FacesContext .getCurrentInstance().getExternalContext().getRequest(); HttpServletResponse response = (HttpServletResponse) FacesContext .getCurrentInstance().getExternalContext().getResponse(); Twitter twitter = TwitterFactory.getSingleton(); twitter.setOAuthConsumer(apiKey, apiSecret); RequestToken requestToken = twitter.getOAuthRequestToken(); if (requestToken != null) { AccessToken accessToken = null; BufferedReader br = new BufferedReader(new InputStreamReader( System.in)); while (null == accessToken) { try { String pin = br.readLine(); accessToken = twitter .getOAuthAccessToken(requestToken, pin); } catch (TwitterException te) { System.out .println("Failed to get access token, caused by: " + te.getMessage()); System.out.println("Retry input PIN"); } } request.setAttribute(IS_AUTHENTICATED, true); if (accessToken != null) { LOGGER.debug("We have a valid oauth token! Make the facebook request"); doApiCall(twitter, request, response); return null; } } else { LOGGER.debug("We don't have auth code yet, fetching the Authorization URL..."); String authorizationUrl = requestToken.getAuthorizationURL(); LOGGER.debug("Redirecting to the Authorization URL: {}", authorizationUrl); request.setAttribute(IS_AUTHENTICATED, false); redirect(authorizationUrl, response); return null; } return null; } In above code i want first Login window of twitter will show and then again same method will call and after user will login i can show user information userId,Handel,location etc. Redirect private void redirect(String url, HttpServletResponse response) throws IOException { String urlWithSessionID = response.encodeRedirectURL(url); response.sendRedirect(urlWithSessionID); } But this code is not working Can anyone tell better Solution for this ?

Arrays and For Loop [closed]

- by java

I wrote this code: import java.io.*; public class dictionary { public static void main(String args[]) { String[] MyArrayE=new String[5]; String[] MyArrayS=new String[5]; String[] MyArrayA=new String[5]; MyArrayE[0]="Language"; MyArrayE[1]="Computer"; MyArrayE[2]="Engineer"; MyArrayE[3]="Home"; MyArrayE[4]="Table"; MyArrayS[0]="Lingua"; MyArrayS[1]="Computador"; MyArrayS[2]="Ing."; MyArrayS[3]="Casa"; MyArrayS[4]="Mesa"; System.out.println("Please enter a word"); BufferedReader br = new BufferedReader(new InputStreamReader(System.in)); String word= null; try { word= br.readLine(); } catch (IOException e) { System.out.println("Error!"); System.exit(1); } System.out.println("Your word is " + word); for(int i=0; i<MyArrayA.length; i++) { if(word.equals(MyArrayS[i])) { System.out.println(MyArrayE[i]); } } } } My Question: What about if the user inputs a word not in MyArrayS, I want to check that and print a statement like "Word does not exist". I think that it might look like: if(word!=MyArrayS) { System.out.println("Word does not exist"); }

Reading data in from file

- by user667430

Hi Here is link if you want to download application: Simple banking app Text file with data to read I am trying to create a simple banking application that reads in data from a text file. So far i have managed to read in all the customers which there are 20 of them. However when reading in the accounts and transactions stuff it only reads in 20 but there is alot more in the text file. Here is what i have so far. I think it has something to do with the nested for loop in the getNextCustomer method. using System; using System.Collections; using System.Collections.Generic; using System.ComponentModel; using System.Data; using System.Drawing; using System.IO; using System.Linq; using System.Text; using System.Windows.Forms; namespace e_SOFT_Banking { public partial class Form1 : Form { public static ArrayList bankDetails = new ArrayList();
