  • Looping through a file in VB.NET

    - by Ousman
    I am writing a VB.NET program and I'm trying to accomplish the following: Read and loop through a text file line by line Show the event of the loop on a textbox or label until a button is pressed The loop will then stop on any number that happened to be at the loop event and When a button is pressed again the loop will continue. Code Imports System.IO Public Class Form1 'Dim nFileNum As Integer = FreeFile() ' Get a free file number Dim strFileName As String = "C:\scb.txt" Dim objFilename As FileStream = New FileStream(strFileName, _ FileMode.Open, FileAccess.Read, FileShare.Read) Dim objFileRead As StreamReader = New StreamReader(objFilename) 'Dim lLineCount As Long 'Dim sNextLine As String Private Sub btStart_Click(ByVal sender As System.Object, _ ByVal e As System.EventArgs) _ Handles btStart.Click Try If objFileRead.ReadLine = Nothing Then MsgBox("No Accounts Available to show!", _ MsgBoxStyle.Information, _ MsgBoxStyle.DefaultButton2 = MsgBoxStyle.OkOnly) Return Else Do While (objFileRead.Peek() > -1) Loop lblAccounts.Text = objFileRead.ReadLine() 'objFileRead.Close() 'objFilename.Close() End If Catch ex As Exception MessageBox.Show(ex.Message) Finally 'objFileRead.Close() 'objFilename.Close() End Try End Sub Private Sub Form1_Load(ByVal sender As System.Object, _ ByVal e As System.EventArgs) _ Handles MyBase.Load End Sub End Class Problem I'm able to read the text file but my label will only loop if I hit the start button. It goes to the next line, but I want it to continue to loop through the entire file until I hit a button telling it to stop.

  • Performance difference in for loop condition?

    - by CSharperWithJava
    Hello all, I have a simple question that I am posing mostly for my curiousity. What are the differences between these two lines of code? (in C++) for(int i = 0; i < N, N > 0; i++) for(int i = 0; i < N && N > 0; i++) The selection of the conditions is completely arbitrary, I'm just interested in the differences between , and &&. I'm not a beginner to coding by any means, but I've never bothered with the comma operator. Are there performance/behavior differences or is it purely aesthetic? One last note, I know there are bigger performance fish to fry than a conditional operator, but I'm just curious. Indulge me. Edit Thanks for your answers. It turns out the code that prompted this question had misused the comma operator in the way I've described. I wondered what the difference was and why it wasn't a && operator, but it was just written incorrectly. I didn't think anything was wrong with it because it worked just fine. Thanks for straightening me out.

  • Newb Question: scanf() in C

    - by riemannliness
    So I started learning C today, and as an exercise i was told to write a program that asks the user for numbers until they type a 0, then adds the even ones and the odd ones together. Here is is (don't laugh at my bad style): #include <stdio.h>; int main() { int esum = 0, osum = 0; int n, mod; puts("Please enter some numbers, 0 to terminate:"); scanf("%d", &n); while (n != 0) { mod = n % 2; switch(mod) { case 0: esum += n; break; case 1: osum += n; } scanf("%d", &n); } printf("The sum of evens:%d,\t The sum of odds:%d", esum, osum); return 0; } My question concerns the mechanics of the scanf() function. It seems that when you enter several numbers at once separated by spaces (eg. 1 22 34 2 8), the scanf() function somehow remembers each distinct numbers in the line, and steps through the while loop for each one respectively. Why/how does this happen? Example interaction within command prompt: - Please enter some numbers, 0 to terminate: 42 8 77 23 11 (enter) 0 (enter) - The sum of evens:50, The sum of odds:111 I'm running the program through the command prompt, it's compiled for win32 platforms with visual studio.

  • Recursion inside while loop, How does it work ?

    - by M.H
    Can you please tell me how does this java code work? : public class Main { public static void main (String[] args) { Strangemethod(5); } public static void Strangemethod(int len) { while(len > 1){ System.out.println(len-1); Strangemethod(len - 1); } } } I tried to debug it and follow the code step by step but I didn't understand it.

  • Why can't I roll a loop in Javascript?

    - by Carl Manaster
    I am working on a web page that uses dojo and has a number (6 in my test case, but variable in general) of project widgets on it. I'm invoking dojo.addOnLoad(init), and in my init() function I have these lines: dojo.connect(dijit.byId("project" + 0).InputNode, "onChange", function() {makeMatch(0);}); dojo.connect(dijit.byId("project" + 1).InputNode, "onChange", function() {makeMatch(1);}); dojo.connect(dijit.byId("project" + 2).InputNode, "onChange", function() {makeMatch(2);}); dojo.connect(dijit.byId("project" + 3).InputNode, "onChange", function() {makeMatch(3);}); dojo.connect(dijit.byId("project" + 4).InputNode, "onChange", function() {makeMatch(4);}); dojo.connect(dijit.byId("project" + 5).InputNode, "onChange", function() {makeMatch(5);}); and change events for my project widgets properly invoke the makeMatch function. But if I replace them with a loop: for (var i = 0; i < 6; i++) dojo.connect(dijit.byId("project" + i).InputNode, "onChange", function() {makeMatch(i);}); same makeMatch() function, same init() invocation, same everything else - just rolling my calls up into a loop - the makeMatch function is never called; the objects are not wired. What's going on, and how do I fix it? I've tried using dojo.query, but its behavior is the same as the for loop case.

  • Doesn't JavaScript support closures with local variables?

    - by qollin
    I am very puzzled about this code: var closures = []; function create() { for (var i = 0; i < 5; i++) { closures[i] = function() { alert("i = " + i); }; } } function run() { for (var i = 0; i < 5; i++) { closures[i](); } } create(); run(); From my understanding it should print 0,1,2,3,4 (isn't this the concept of closures?). Instead it prints 5,5,5,5,5. I tried Rhino and Firefox. Could someone explain this behavior to me? Thx in advance.

  • openmp program elapsed time not scaling with increased threads

    - by Griff
    I've got this openmp fortran program doing an embarrassingly parallel problem - do loop over 512^3 elements. See output below. Why would there be such strange behavior in the elapsed time as a function of threads? I thought it would peak at a sweet spot then slowly degrade. This clearly isn't happening. Perhaps I misunderstand something about openmp. Threads, omp_get_wtime 1, 103.76298500015400 2, 65.346454000100493 4, 45.923643999965861 7, 38.074195000110194 8, 36.968765000114217 9, 39.45981499995105 10,40.753379000118002 12,39.577559999888763 14,37.909950000001118

  • Stuck in Infinite Loop while PostInvalidating

    - by Nicholas Roge
    I'm trying to test something, however, the loop I'm using keeps getting stuck while running. It's just a basic lock thread while doing something else before continuing kind of loop. I've double checked that I'm locking AND unlocking the variable I'm using, but regardless it's still stuck in the loop. Here are the segments of code I have that cause the problem: ActualGame.java: Thread thread=new Thread("Dialogue Thread"){ @Override public void run(){ Timer fireTimer=new Timer(); int arrowSequence=0; gameHandler.setOnTouchListener( new OnTouchListener(){ @Override public boolean onTouch(View v, MotionEvent me) { //Do something. if(!gameHandler.fireTimer.getActive()){ exitLoop=true; } return false; } } ); while(!exitLoop){ while(fireTimer.getActive()||!gameHandler.drawn); c.drawBitmap(SpriteSheet.createSingleBitmap(getResources(), R.drawable.dialogue_box,240,48),-48,0,null); c.drawBitmap(SpriteSheet.createSingleBitmap(getResources(),R.drawable.dialogue_continuearrow,32,16,8,16,arrowSequence,0),-16,8,null); gameHandler.drawn=false; gameHandler.postInvalidate(); if(arrowSequence+1==4){ arrowSequence=0; exitLoop=true; }else{ arrowSequence++; } fireTimer.startWait(100); } gameHandler.setOnTouchListener(gameHandler.defaultOnTouchListener); } }; thread.run(); And the onDraw method of GameHandler: canvas.scale(scale,scale); canvas.translate(((screenWidth/2)-((terrainWidth*scale)/2))/scale,((screenHeight/2)-((terrainHeight*scale)/2))/scale); canvas.drawColor(Color.BLACK); for(int layer=0;layer(less than)tiles.length;layer++){ if(layer==playerLayer){ canvas.drawBitmap(playerSprite.getCurrentSprite(), playerSprite.getPixelLocationX(), playerSprite.getPixelLocationY(), null); continue; } for(int y=0;y(less than)tiles[layer].length;y++){ for(int x=0;x(less than)tiles[layer][y].length;x++){ if(layer==0&&tiles[layer][y][x]==null){ tiles[layer][y][x]=nullTile; } if(tiles[layer][y][x]!=null){ runningFromTileEvent=false; canvas.drawBitmap(tiles[layer][y][x].associatedSprite.getCurrentSprite(),x*tiles[layer][y][x].associatedSprite.spriteWidth,y*tiles[layer][y][x].associatedSprite.spriteHeight,null); } } } } for(int i=0;i(less than)canvasEvents.size();i++){ if(canvasEvents.elementAt(i).condition(this)){ canvasEvents.elementAt(i).run(canvas,this); } } Log.e("JapaneseTutor","Got here.[1]"); drawn=true; Log.e("JapaneseTutor","Got here.[2]"); If you need to see the Timer class, or the full length of the GameHandler or ActualGame classes, just let me know.

  • How do I get a less than in a javascript for loop in XSL to work?

    - by Kyle
    I am using CDATA to escape the script but in IE8's debugger I still get this message: "Expected ')'" in the for loop conditions. I am assuming it still thinks that the ; in the &lt; generated by CDATA is ending the loop conditions. Original script in my XSL template: <script type="text/javascript" language="javascript"> <![CDATA[ function submitform(form){ var oErrorArray = new Array(); for (i=0;i<form.length;i++) eval("oErrorArray["+i+"]=oError"+i); var goForm = true; for(i=0;i<form.length;i++) { oErrorArray[i].innerHTML = ""; if(form[i].value="")){ oErrorArray[i].innerHTML = "Error - input field is blank"; goForm = false; } } if(goForm == true) form.submit(); } function resetform(form){ form.reset(); } ]]> </script> Code generated after transformation (from IE8 debugger): <script type="text/javascript" language="javascript"> function submitform(form){ var oErrorArray = new Array(); for (i=0;i&lt;form.length;i++) eval("oErrorArray["+i+"]=oError"+i); goForm = true; for(i=0;i&lt;form.length;i++) { oErrorArray[i].innerHTML = ""; if(form[i].value="")){ oErrorArray[i].innerHTML = "Error - input field is blank"; goForm = false; } } if(goForm == true) form.submit(); } function resetform(form){ form.reset(); } </script> Error reported by IE8 debugger: Expected ')' login.xml, line 29 character 30 (which is right after the first "form.length")

  • Android - Looping Activity to Repeat MediaPlayer

    - by Austin Anderson
    I'm trying to create a soundboard for longer audio files and can't figure out how to stop an audio file and start it again without closing the activity. Let's say each audio file is one minute long. If I play the first audio file for 20 seconds and start the next audio file, the first stops playing and the second starts playing. However, if I click the first audio file again, the second stops playing and the first does not. I need help. This is driving me insane. bAudio1 = (ImageButton) findViewById(R.id.bAudio1); bAudio2 = (ImageButton) findViewById(R.id.bAudio2); mpAudio1 = MediaPlayer.create(this, R.raw.audio1); mpAudio2 = MediaPlayer.create(this, R.raw.audio2); bAudio1.setOnClickListener(new View.OnClickListener() { public void onClick(View v) { if(mpAudio1.isPlaying()) { mpAudio1.stop(); } else { if(mpAudio2.isPlaying()) { mpAudio2.stop(); } mpAudio1.start(); } } }); bAudio2.setOnClickListener(new View.OnClickListener() { public void onClick(View v) { if(mpAudio2.isPlaying()) { mpAudio2.stop(); } else { if(mpAudio1.isPlaying()) { mpAudio1.stop(); } mpAudio2.start(); } } }); Thanks.

  • Trying to create an image list based on what is defined as the order, and loosing

    - by user1691463
    I have a custom created module for Joomla 2.5 and within the params of the module, and have a loop that is not outputting as expected. I have the following parameters (fields) int he module: Order Thumb image Image Title Full-size image Now there are 10 sets of these group of 4 params. What I am trying to do is loop through each of the object sets, 10 of them, and on each iteration, build an HTML image list structure. The if statement is building the HTML structure for the sets that have an order value that is greater than 0, and the else is creating the html for those sets that do not have a value greater that 0. The goal is to create two variables and then concatenate the the strings together; the leading set are the sets that have an order defined. This is not happening and every thrid loop seems like it is missing. Here is the order as it is set in the 10 sets Set 1 = 0 Set 2 = 4 Set 3 = 1 Set 4 = 0 Set 5 = 5 Set 6 = 0 Set 7 = 0 Set 8 = 6 Set 9 = 3 Set 10 = 9 However, the outcomes is: 9 5 1 4 6 7 10 Instead of the expected: 3 9 2 5 8 1 (below here are those sets that were not greater than 0 in order of appearance) 4 6 7 whats wrong here that I can not see <?php for ($i = 1; $i <= 10; $i++) { $order = $params->get('order'.$i);#get order for main loop of 10 $active = ""; if ($order > 0) {#Check if greater than 0 for ($n = 1; $n <= 10; $n++) {#loop through all order fields looking and build html lowest to highest; $ordercheck =$params->get('order'.$n); if ($ordercheck == $i) { $img = $params->get('image'.$n); $fimage = $params->get('image'.$n.'fullimage'); $title = $params->get('image'.$n.'alttext'); $active = ""; $active = $active .

  • How to store multiple variables from a File Input of unknown size in Java?

    - by AlphaOmegaStrife
    I'm a total beginner with my first programming assignment in Java. For our programming assignment, we will be given a .txt file of students like so: 3 345 Lisa Miller 890238 Y 2 <-(Number of classes) Mathematics MTH345 4 A Physics PHY357 3 B Bill Wilton 798324 N 2 English ENG378 3 B Philosophy PHL534 3 A Dandy Goat 746333 Y 1 History HIS101 3 A" The teacher will give us a .txt file on the day of turning it in with a list of unknown students. My problem is: I have a specific class for turning the data from the file into variables to be used for a different class in printing it to the screen. However, I do not know of a good way to get the variables from the input file for the course numbers, since that number is not predetermined. The only way I can think of to iterate over that unknown amount is using a loop, but that would just overwrite my variables every time. Also, the teacher has requested that we not use any JCL classes (I don't really know what this means.) Sorry if I have done a poor job of explaining this, but I can't think of a better way to conceptualize it. Let me know if I can clarify. Edit: public static void analyzeData() { Scanner inputStream = null; try { inputStream = new Scanner(new FileInputStream("Programming Assignment 1 Data.txt")); } catch (FileNotFoundException e) { System.out.println("File Programming Assignment 1 Data.txt could not be found or opened."); System.exit(0); } int numberOfStudents = inputStream.nextInt(); int tuitionPerHour = inputStream.nextInt(); String firstName = inputStream.next(); String lastname = inputStream.next(); String isTuitionPaid = inputStream.next(); int numberOfCourses = inputStream.nextInt(); String courseName = inputStream.next(); String courseNumber = inputStream.next(); int creditHours = inputStream.nextInt(); String grade = inputStream.next(); To show the methods I am using now, I am just using a Scanner to read from the file and for Scanner inputStream, I am using nextInt() or next() to get variables from the file. Obviously this will not work when I do not know exactly how many classes each student will have.

  • Searching in an Arraylist

    Currently I have two classes. A Classroom class and a School class. I would like to write a method in the School class public void showClassRoomDetails which would find the classroom details by only using the teacherName. e.g. teacherName = Daniel className = Science teacherName = Bob className = Maths so when I input Bob, it would print out Bob and Maths many, thanks public class Classroom { private String classRoomName; private String teacherName; public void setClassRoomName(String newClassRoomName) { classRoomName = newClassRoomName; } public String returnClassRoomName() { return classRoomName; } public void setTeacherName(String newTeacherName) { teacherName = newTeacherName; } public String returnTeacherName() { return teacherName; } } import java.util.ArrayList; public class School { private ArrayList<Classroom> classrooms; private String classRoomName; private String teacherName; public School() { classrooms = new ArrayList<Classroom>(); } public void addClassRoom(Classroom newClassRoom, String theClassRoomName) { classrooms.add(newClassRoom); classRoomName = theClassRoomName; } public void addTeacherToClassRoom(int classroomId, String TeacherName) { if (classroomId < classrooms.size() ) { classrooms.get(classroomId).setTeacherName(TeacherName); } } public void showClassRoomDetails { //loop System.out.println(returnClassRoomName); System.out.println(returnTeacherName); } }

  • Sort command not working as expected

    - by user964689
    If anybody can help me to write a loop to iterate over files in a folder it would save me a huge amount of time. I think it must be quite a simple solution ,but I currently don't know how to nest a loop within a loop. So far I have this script: cd /folderlocation/ for i in `</textfile_containing_lines_to_iterate_through` do #size=`echo $i | perl -nE '/:([\d-]+)/ && say abs(eval $1)'` #echo "$size" zcat dataset | head -n 18 > temp"$i".vcf tabix dataset $i >> temp"$i".vcf vcftools --window-pi 1000000 --vcf temp10individuals"$i".vcf >> run_summary.txt cat out.windowed.pi >> outputfile_2 #rm temp* done grep -v "PI" outputfile_2 > outputfile rm outputfile_2 I need to expand this so that the script will run multiple times, through all of the 'textfiles_containing_lines_to_iterate_through'. Currently I change the name of the textfile manually each time and re-run the script. So I'd need a loop that does this for file in folder, and also that uses the name of the file as part of the outputfile name so that I can match an output file to an inputfile. Any help would be really useful and greatly appreciated! Many thanks in advance.

  • Looping through array in PHP to post several multipart form-data

    - by Léon Pelletier
    I'm trying in an asp web application to code a function that would loop through a list of files in a multiple upload form and send them one by one. Is this something that can be done in ASP? Because I've read some posts about how to attach several files together, but saw nothing about looping through the files. I can easily imagine it in C# via HttpWebRequest or with socket, but in php, I guess there are already function designed to handle it? // This is false/pseudo-code :) for (int index = 0; index < number_of_files; index++) { postfile(file[index]); } And in each iteration, it should send a multipart form-data POST. postfile(TheFileInfos) should make a POST like it: POST /afs.aspx?fn=upload HTTP/1.1 [Header stuff] Content-Type: multipart/form-data; boundary=----------Ef1Ef1cH2Ij5GI3ae0gL6KM7GI3GI3 [Header stuff] ------------Ef1Ef1cH2Ij5GI3ae0gL6KM7GI3GI3 Content-Disposition: form-data; name="Filename" myimage1.png ------------Ef1Ef1cH2Ij5GI3ae0gL6KM7GI3GI3 Content-Disposition: form-data; name="fileid" 58e21ede4ead43a5201206101806420000007667212251 ------------Ef1Ef1cH2Ij5GI3ae0gL6KM7GI3GI3 Content-Disposition: form-data; name="Filedata"; filename="myimage1.png" Content-Type: application/octet-stream [Octet Stream] [Edit] I'll try it: <html> <head> <title>Untitled Document</title> <meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1"> </head> <body> <form name="form1" enctype="multipart/form-data" method="post" action="processFiles.php"> <p> <? // start of dynamic form $uploadNeed = $_POST['uploadNeed']; for($x=0;$x<$uploadNeed;$x++){ ?> <input name="uploadFile<? echo $x;?>" type="file" id="uploadFile<? echo $x;?>"> </p> <? // end of for loop } ?> <p><input name="uploadNeed" type="hidden" value="<? echo $uploadNeed;?>"> <input type="submit" name="Submit" value="Submit"> </p> </form> </body> </html>

  • Looping through Markers with Google Maps API v3 Problem

    - by Oscar Godson
    I'm not sure why this isn't working. I don't have any errors, but what happens is, no matter what marker I click on, it clicks the 3rd one (which is the last one out of 4 markers. Array starts at 0, obviously) and shows the number "3", which is correct for THAT one, but I'm not clicking that one. Here is most of my code, just not the array of [place-name, coordinates] (var locations, which you will see): function initialize() { var latlng = new google.maps.LatLng(45.522015,-122.683811); var settings = { zoom: 15, center: latlng, disableDefaultUI:true, mapTypeId: google.maps.MapTypeId.SATELLITE }; var map = new google.maps.Map(document.getElementById("map_canvas"), settings); var infowindow = new Array(); var marker = new Array(); for(x in locations){ console.log(x); infowindow[x] = new google.maps.InfoWindow({content: x}); marker[x] = new google.maps.Marker({title:locations[x][0],map:map,position:locations[x][1]}); google.maps.event.addListener(marker[x], 'click', function() {infowindow[x].open(map,marker[x]);}); } } initialize() The console.log output is (its correct, and what i expect): 0 1 2 3 So, any ideas?

  • PHP script stops running arbitrarily with no errors.

    - by RobHardgood
    I was working on a fairly long script that seemed to stop running after about 20 minutes. After days of trying to figure out why, I decided to make a very simple script to see how long it would run without any complex code to confuse me. I found that the same thing was happening with this simple infinite loop. At some point between 15 and 25 minutes of running, it simply stopped. There is no error output at all. The bottom of the browser simply says "Done" and nothing else is processed. I've been over every single possible thing I could think of... set_time_limit, session.gc_maxlifetime in the php.ini as well as memory_limit and max_execution_time. The point that the script is stopped is never consistent. Sometimes it will stop at 15 minutes, sometimes 22 minutes, sometimes 17... But it's always long enough to be a PITA to test. Please, any help would be greatly appreciated. It is hosted on a 1and1 server. I contacted them and they couldn't help me... but I have a feeling they just didn't know enough.

  • SASS color array

    - by Eric Holmes
    I am trying to write a loop that will cycle through colors and condense the amount of code in my scss file. Here is a simple example of what I have: $color1: blue; $color2: red; $color3: white; $color4: black; .color1-bg { background-color: $color1; } .color2-bg { background-color: $color2; } .color1-border { border-color: $color1; } .color2-border { border-color: $color2; } And so on. I am looking for a way to make the equivalent of a foreach loop, and cycle through an 'array' of colours by index. Something like this: @each $color in $color1, $color2, $color3, $color4 { .{$color}-bg { background-color: $color; .{$color}-border { border-color: $color; } I know the syntax is wrong, but that is my thinking process. Thanks for the help!

  • iPhone game and reading plist file and looping through multidimensional array.

    - by Fulvio
    I have a question regarding an iPhone game I'm developing. At the moment, below is the code I'm using to currently I loop through my multidimensional array and position bricks accordingly on my scene. Instead of having multiple two dimensional arrays within my code as per the following (gameLevel1). Ideally, I'd like to read from a .plist file within my project and loop through the values in that instead. Please take into account that I'd like to have more than one level within my game (possibly 20) so my .plist file would have to have some sort of separator line item to determine what level I want to render. I was then thinking of having some sort of method that I call and that method would take the level number I'm interested in rendering. e.g. Method? +(void)renderLevel:(NSString levelNumber); e.g. .plist file? #LEVEL_ONE# 0,0,0,0,0,0,0,0,0 0,1,1,1,1,1,1,1,0 0,1,1,1,1,1,1,1,0 0,1,1,1,1,1,1,1,0 0,1,1,1,1,1,1,1,0 0,1,1,1,1,1,1,1,0 0,1,1,1,1,1,1,1,0 0,1,1,1,1,1,1,1,0 0,1,1,1,1,1,1,1,0 0,1,1,1,1,1,1,1,0 0,1,1,1,1,1,1,1,0 0,1,1,1,1,1,1,1,0 0,1,1,1,1,1,1,1,0 0,1,1,1,1,1,1,1,0 0,1,1,1,1,1,1,1,0 0,1,1,1,1,1,1,1,0 0,0,0,0,0,0,0,0,0 #LEVEL_TWO# 1,0,0,0,0,0,0,0,1 1,1,1,1,1,1,1,1,1 1,1,1,1,1,1,1,1,1 1,1,1,1,1,1,1,1,1 1,1,1,1,1,1,1,1,1 0,1,1,1,1,1,1,1,0 1,1,1,1,1,1,1,1,1 0,1,1,1,1,1,1,1,0 1,1,1,1,1,1,1,1,1 0,1,1,1,1,1,1,1,0 1,1,1,1,1,1,1,1,1 0,1,1,1,1,1,1,1,0 1,1,1,1,1,1,1,1,1 1,1,1,1,1,1,1,1,1 1,1,1,1,1,1,1,1,1 1,1,1,1,1,1,1,1,1 1,0,0,0,0,0,0,0,1 Code that I'm currently using: int gameLevel[17][9] = { { 0,0,0,0,0,0,0,0,0 }, { 0,1,1,1,1,1,1,1,0 }, { 0,1,1,1,1,1,1,1,0 }, { 0,1,1,1,1,1,1,1,0 }, { 0,1,1,1,1,1,1,1,0 }, { 0,1,1,1,1,1,1,1,0 }, { 0,1,1,1,1,1,1,1,0 }, { 0,1,1,1,1,1,1,1,0 }, { 0,1,1,1,1,1,1,1,0 }, { 0,1,1,1,1,1,1,1,0 }, { 0,1,1,1,1,1,1,1,0 }, { 0,1,1,1,1,1,1,1,0 }, { 0,1,1,1,1,1,1,1,0 }, { 0,1,1,1,1,1,1,1,0 }, { 0,1,1,1,1,1,1,1,0 }, { 0,1,1,1,1,1,1,1,0 }, { 0,0,0,0,0,0,0,0,0 } }; for (int row=0; row < 17; row++) { for (int col=0; col < 17; col++) { thisBrickValue = gameLevel[row][col]; xOffset = 35 * floor(col); yOffset = 22 * floor(row); switch (thisBrickValue) { case 0: brick = [[CCSprite spriteWithFile:@"block1.png"] autorelease]; break; case 1: brick = [[CCSprite spriteWithFile:@"block0.png"] autorelease]; break; } brick.position = ccp(xOffset, yOffset); [self addChild:brick]; } }

  • How to print an isosceles triangle

    - by Steve
    Hello, I'm trying to learn programming by myself, I'm working from a book that has the following problem which I can't solve: Allow the user to input two values: a character to be used for printing an isosceles triangle and the size of the peak for the triangle. For example, if the user inputs # for the character and 6 for the peak, you should produce the following display: # ## ### #### ##### ###### ##### #### ### ## # This is the code I've got so far: char character; int peak; InputValues(out character, out peak); for (int row = 1; row < peak * 2; row++) { for (int col = 1; col <= row; col++) { Console.Write(character); } Console.WriteLine(); } Console.Read() // hold console open Thanks in advance.

How can i develop this.please help me This is my code: ImageButton mImgAddCart = (ImageButton) findViewById(R.id.img_add); mImgAddCart.setOnClickListener(new OnClickListener() { public void onClick(View v) { // TODO Auto-generated method stub mTitle = txttitle.getText().toString(); mCost = text_cost_code.getText().toString(); mCost = mCost.replace("From ", ""); mTotal = txt_total.getText().toString(); mTotal = mTotal.replace("From ", ""); mQty = edit_qty_code.getText().toString(); if (Constants.mItem_Detail.size() <= 0) { HashMap<String, String> mTempObj = new HashMap<String, String>(); mTempObj.put(KEY_TITLE, mTitle); mTempObj.put(KEY_QTY, mQty); mTempObj.put(KEY_COST, mCost); mTempObj.put(KEY_TOTAL, mTotal); Constants.mItem_Detail.add(mTempObj); } else { for (int i = 0; i < Constants.mItem_Detail.size(); i++) { if (Constants.mItem_Detail.get(i).get(KEY_TITLE) .equals(mTitle)) { Constants.mItem_Detail.remove(i); break; } else { } } HashMap<String, String> mTempObj = new HashMap<String, String>(); mTempObj.put(KEY_TITLE, mTitle); mTempObj.put(KEY_QTY, mQty); mTempObj.put(KEY_COST, mCost); mTempObj.put(KEY_TOTAL, mTotal); Constants.mItem_Detail.add(mTempObj); } AlertDialog.Builder alertdialog = new AlertDialog.Builder( Small.this); alertdialog.setTitle(getResources() .getString(R.string.app_name)); alertdialog.setMessage("Add in ViewCart"); alertdialog.setPositiveButton("OK", new DialogInterface.OnClickListener() { @Override public void onClick(DialogInterface dialog, int which) { // TODO Auto-generated method stub finish(); } }); alertdialog.show(); } }); How can i set the condition for this.please give me one idea.

  • Why I can't draw in a loop? (Using UIView in iPhone)

    - by Tattat
    I can draw many things using this : NSString *imagePath = [[NSBundle mainBundle] pathForResource:@"dummy2.png" ofType:nil]; UIImage *img = [UIImage imageWithContentsOfFile:imagePath]; image = CGImageRetain(img.CGImage); CGRect imageRect; double x = 0; double y = 0; for (int k=0; k<someValue; k++) { x += k; y += k; imageRect.origin = CGPointMake(x, y); imageRect.size = CGSizeMake(25, 25); CGContextDrawImage(UIGraphicsGetCurrentContext(), imageRect, image); } } CGImageRelease(img.CGImage); So, it works, so, I put it into a command object's execute method. Then, I want to do similar thing, but this time, my execute method only do this: NSString *imagePath = [[NSBundle mainBundle] pathForResource:@"dummy2.png" ofType:nil]; UIImage *img = [UIImage imageWithContentsOfFile:imagePath]; image = CGImageRetain(img.CGImage); CGRect imageRect; double x = inComingX; double y = inComingY; imageRect.origin = CGPointMake(x, y); imageRect.size = CGSizeMake(25, 25); CGContextDrawImage(UIGraphicsGetCurrentContext(), imageRect, image); CGImageRelease(img.CGImage); This time, this is also a Command, and it is the execute method. But I take the for loop away. I will have another method that pass the inComingX , and inComingY into my Command object. My Drawing method is simply execute the Cmd that passed in my drawingEngine: -(void)drawInContext:(CGContextRef)context { [self.cmdToBeExecuted execute]; } I also have the assign method to assign the command,: -(void)assignCmd:(Command* )cmd{ self.cmdToBeExecuted = cmd; } And this is the way I called the drawingEngine for(int k=0; k<5; k++){ [self.drawingEngine assignCmd:[DrawingCmd setDrawingInformation:(10*k):0:@"dummy.png"]]; [self.drawingEngine setNeedsDisplay]; } It can draw, but the sad thing is it only draw the last one. Why? and how to fix it? I can draw all the things in my First code, but after I take the loop outside, and use the loop in last code, it just only draw the last one. Plz help
