  • Converting text into numeric in xls using Java

    - by Work World
    When I create excel sheet through java ,the column which has number datatype in the oracle table, get converted to text format in excel.I want it to remain in the number format.Below is my code snippet for excel creation. FileWriter fw = new FileWriter(tempFile.getAbsoluteFile(),true); // BufferedWriter bw = new BufferedWriter(fw); HSSFWorkbook wb = new HSSFWorkbook(); HSSFSheet sheet = wb.createSheet("Excel Sheet"); //Column Size of excel for(int i=0;i<10;i++) { sheet.setColumnWidth((short) i, (short)8000); } String userSelectedValues=result; HSSFCellStyle style = wb.createCellStyle(); ///HSSFDataFormat df = wb.createDataFormat(); style.setFillForegroundColor(HSSFColor.GREY_25_PERCENT.index); style.setFillPattern(HSSFCellStyle.SOLID_FOREGROUND); //style.setDataFormat(df.getFormat("0")); HSSFFont font = wb.createFont(); font.setColor(HSSFColor.BLACK.index); font.setBoldweight((short) 700); style.setFont(font); int selecteditems=userSelectedValues.split(",").length; // HSSFRow rowhead = sheet.createRow((short)0); //System.out.println("**************selecteditems************" +selecteditems); for(int k=0; k<selecteditems;k++) { HSSFRow rowhead = sheet.createRow((short)k); if(userSelectedValues.contains("O_UID")) { HSSFCell cell0 = rowhead.createCell((short) k); cell0.setCellValue("O UID"); cell0.setCellStyle(style); k=k+1; } ///some columns here.. } int index=1; for (int i = 0; i<dataBeanList.size(); i++) { odb=(OppDataBean)dataBeanList.get(i); HSSFRow row = sheet.createRow((short)index); for(int j=0;j<selecteditems;j++) { if(userSelectedValues.contains("O_UID")) { row.createCell((short)j).setCellValue(odb.getUID()); j=j+1; } } index++; } FileOutputStream fileOut = null; try { fileOut = new FileOutputStream(path.toString()+"/temp.xls"); } catch (FileNotFoundException e1) { // TODO Auto-generated catch block e1.printStackTrace(); } try { wb.write(fileOut); } catch (IOException e) { // TODO Auto-generated catch block e.printStackTrace(); } try { fileOut.close(); } catch (IOException e) { // TODO Auto-generated catch block e.printStackTrace(); }

  • add space to every word's end in a string in C

    - by hlx98007
    Here I have a string: *line = "123 567 890 "; with 2 spaces at the end. I wish to add those 2 spaces to 3's end and 7's end to make it like this: "123 567 890" I was trying to achieve the following steps: parse the string into words by words list (array of strings). From upstream function I will get values of variables word_count, *line and remain. concatenate them with a space at the end. add space distributively, with left to right priority, so when a fair division cannot be done, the second to last word's end will have (no. of spaces) spaces, the previous ones will get (spaces + 1) spaces. concatenate everything together to make it a new *line. Here is a part of my faulty code: int add_space(char *line, int remain, int word_count) { if (remain == 0.0) return 0; // Don't need to operate. int ret; char arr[word_count][line_width]; memset(arr, 0, word_count * line_width * sizeof(char)); char *blank = calloc(line_width, sizeof(char)); if (blank == NULL) { fprintf(stderr, "calloc for arr error!\n"); return -1; } for (int i = 0; i < word_count; i++) { ret = sscanf(line, "%s", arr[i]); // gdb shows somehow it won't read in. if (ret != 1) { fprintf(stderr, "Error occured!\n"); return -1; } arr[i] = strcat(arr[i], " "); // won't compile. } size_t spaces = remain / (word_count * 1.0); memset(blank, ' ', spaces + 1); for (int i = 0; i < word_count - 1; i++) { arr[0] = strcat(arr[i], blank); // won't compile. } memset(blank, ' ', spaces); arr[word_count-1] = strcat(arr[word_count-1], blank); for (int i = 1; i < word_count; i++) { arr[0] = strcat(arr[0], arr[i]); } free(blank); return 0; } It is not working, could you help me find the parts that do not work and fix them please? Thank you guys.

  • Counting number of searches

    - by shinjuo
    I am trying to figure out how to get the total number of tests each search makes in this algorithm. I am not sure how I can pass that information back from this algorithm though. I need to count how many times while runs and then pass that number back into an array to be added together and determine the average number of test. main.c #include <stdio.h> #include <stdlib.h> #include <time.h> #include <stdbool.h> #include "percentage.h" #include "sequentialSearch.h" #define searchAmount 100 int main(int argc, char *argv[]) { int numbers[100]; int searches[searchAmount]; int i; int where; int searchSuccess; int searchUnsuccess; int percent; srand(time(NULL)); for (i = 0; i < 100; i++){ numbers[i] = rand() % 200; } for (i = 0; i < searchAmount; i++){ searches[i] = rand() % 200; } searchUnsuccess = 0; searchSuccess = 0; for(i = 0; i < searchAmount; i++){ if(seqSearch(numbers, 100, searches[i], &where)){ searchSuccess++; }else{ searchUnsuccess++; } } percent = percentRate(searchSuccess, searchAmount); printf("Total number of searches: %d\n", searchAmount); printf("Total successful searches: %d\n", searchSuccess); printf("Success Rate: %d%%\n", percent); system("PAUSE"); return 0; } sequentialSearch.h bool seqSearch (int list[], int last, int target, int* locn){ int looker; looker = 0; while(looker < last && target != list[looker]){ looker++; } *locn = looker; return(target == list[looker]); }

  • JQuery Ajax Updating MySQL Database, But Not Running Success Function

    - by myrmidon16
    I am currently using the JQuery ajax function to call an exterior PHP file, in which I select and add data in a database. Once this is done, I run a success function in JavaScript. What's weird is that the database is updating successfully when ajax is called, however the success function is not running. Here is my code: <!DOCTYPE html> <head> <script type="text/javascript" src="jquery-1.6.4.js"></script> </head> <body> <div onclick="addtask();" style="width:400px; height:200px; background:#000000;"></div> <script> function addtask() { var tid = (Math.floor(Math.random() * 3)) + 1; var tsk = (Math.floor(Math.random() * 10)) + 1; if(tsk !== 1) { $.ajax({ type: "POST", url: "taskcheck.php", dataType: "json", data: {taskid:tid}, success: function(task) {alert(task.name);} }); } } </script> </body> </html> And the PHP file: session_start(); $connect = mysql_connect('x', 'x', 'x') or die('Not Connecting'); mysql_select_db('x') or die ('No Database Selected'); $task = $_REQUEST['taskid']; $uid = $_SESSION['user_id']; $q = "SELECT task_id, taskname FROM tasks WHERE task_id=" .$task. " LIMIT 1"; $gettask = mysql_fetch_assoc(mysql_query($q)); $q = "INSERT INTO user_tasks (ut_id, user_id, task_id, taskstatus, taskactive) VALUES (null, " .$uid. ", '{$gettask['task_id']}', 0, 1)"; $puttask = mysql_fetch_assoc(mysql_query($q)); $json = array( "name" => $gettask['taskname'] ); $output = json_encode($json); echo $output; Let me know if you have any questions or comments, thanks.

  • execl doesn't work in a while(1) cicle, server side; C script

    - by Possa
    Hi guys, I have a problem with a little C script who should run as a server and launch a popup for every message arriving. The execl syntax is correct because if I try a little script with main() { execl(...); } it works. When I put it in a while(1) cicle it doesn't work. Everything else is working, like printf or string operation, but not the execl. Even if I fork it doesn't work. I really don't know what I can do ... can anyone help me? Thanks in advice for your help and sorry for my bad english. Here's the complete server C code. #include <arpa/inet.h> #include <netinet/in.h> #include <stdio.h> #include <stdlib.h> #include <sys/types.h> #include <sys/socket.h> #include <unistd.h> #include <string.h> #define BUFLEN 512 #define PORT 9930 void diep(char *s) { perror(s); exit(1); } int main() { struct sockaddr_in si_me, si_other; int s, i, slen=sizeof(si_other), broadcastPermission; char buf[100], zeni[BUFLEN]; if ((s=socket(AF_INET, SOCK_DGRAM, IPPROTO_UDP))==-1) diep("socket"); broadcastPermission = 1; if (setsockopt(s, SOL_SOCKET, SO_BROADCAST, (void *) &broadcastPermission, sizeof(broadcastPermission)) < 0) diep("setsockopt() failed"); memset((char *) &si_me, 0, sizeof(si_me)); si_me.sin_family = AF_INET; si_me.sin_port = htons(PORT); si_me.sin_addr.s_addr = htonl(INADDR_ANY); if (bind(s, &si_me, sizeof(si_me))==-1) diep("bind"); while (1) { if (recvfrom(s, buf, BUFLEN, 0, &si_other, &slen)==-1) diep("recvfrom()"); //printf("Received packet from %s:%d\nData: %s\n", inet_ntoa(si_other.sin_addr), ntohs(si_other.sin_port), buf); strcpy(zeni, ""); strcat(zeni, "zenity --warning --title Hack!! --text "); strcat(zeni, buf); printf("cmd: %s\n", zeni); //system (zeni); execl("/usr/bin/zenity", "/usr/bin/zenity", "--warning", "--title", "Warn!", "--text", buf, (char *) NULL); } close(s); return 0; }

  • C# ApplicationContext usage

    - by rd42
    Apologies if my terminology is off, I'm new to C#. I'm trying to use an ApplicationContext file to store mysql conn values, like dbname, username, password. The class with mysql conn string is "using" the namespace for the ApplicationContext, but when I print out the connection string, the values are making it. A friend said, "I'm not initializing it" but couldn't stay to expand on what "it" was. and the "Console.WriteLine("1");" in ApplicationContext.cs never shows up. Do I need to create an ApplicationContext object and the call Initialize() on that object? Thanks for any help. ApplicationContext.cs: namespace NewApplication.Context { class ApplicationContext { public static string serverName; public static string username; public static string password; public static void Initialize() { //need to read through config here try { Console.WriteLine("1"); XmlDocument xDoc = new XmlDocument(); xDoc.Load(".\\Settings.xml"); XmlNodeList serverNodeList = xDoc.GetElementsByTagName("DatabaseServer"); XmlNodeList usernameNodeList = xDoc.GetElementsByTagName("UserName"); XmlNodeList passwordNodeList = xDoc.GetElementsByTagName("Password"); } catch (Exception ex) { // MessageBox.Show(ex.ToString()); //TODO: Future write to log file username = "user"; password = "password"; serverName = "localhost"; } } } } MySQLManager.cs: note: dbname is the same as the username as you'll see in the code, I copied this from a friend who does that. using System; using System.Collections.Generic; using System.Linq; using System.Text; using MySql.Data; using MySql.Data.MySqlClient; using NewApplication.Context; namespace NewApplication.DAO { class MySQLManager { private static MySqlConnection conn; public static MySqlConnection getConnection() { if (conn == null || conn.State == System.Data.ConnectionState.Closed) { string connStr = "server=" + ApplicationContext.serverName + ";user=" + ApplicationContext.username + ";database=" + ApplicationContext.username + ";port=3306;password=" + ApplicationContext.password + ";"; conn = new MySqlConnection(connStr); try { Console.WriteLine("Connecting to MySQL... "); Console.WriteLine("Connection string: " + connStr + "\n"); conn.Open(); // Perform databse operations // conn.Close(); } catch (Exception ex) { Console.WriteLine(ex.ToString()); } } return conn; } } } and, thanks for still reading, this is the code that uses the two previous files: class LogDAO { MySqlConnection conn; public LogDAO() { conn = MySQLManager.getConnection(); } Thank you, rd42

  • How to facebook getuser() after login with javascript SDK

    - by user1848205
    So I have to ask for extended permission by clicking the enter button, but after the login is necessary to refresh the page in order to display the app. Here's my code: <?php require 'facebook.php'; $facebook = new Facebook(array( 'appId' => '< THE APPID >', 'secret' => '< THE SECRET >', 'cookie' => true, )); $user = $facebook->getUser(); if ($user) { try { $user_profile = $facebook->api('/me'); } catch (FacebookApiException $e) { error_log($e); $user = null; } } ?> <body> <div id="fb-root"></div> <script> window.fbAsyncInit = function() { FB.init({ appId : '< THE APPID >', status : true, cookie : true, xfbml : true }); // Additional initialization code such as adding Event Listeners goes here $('#btn-enter').click(function(){ login(); }); }; (function(d){ var js, id = 'facebook-jssdk', ref = d.getElementsByTagName('script')[0]; if (d.getElementById(id)) {return;} js = d.createElement('script'); js.id = id; js.async = true; js.src = "//connect.facebook.net/en_US/all.js"; ref.parentNode.insertBefore(js, ref); }(document)); function login() { FB.login(function(response) { if (response.authResponse) { // connected } else { // cancelled } //}); }, {scope: 'read_friendlists,friends_photos,publish_stream'}); } </script> <?php if ($user): ?> <!--Here is my APP--> <?php else: ?> <a id="btn-enter">Enter</a> <?php endif ?> Is there a better way to do this ? What works for me is: function login() { FB.login(function(response) { if (response.authResponse) { top.location.href='https://the_app_url'; } else { } //}); }, {scope: 'read_friendlists,friends_photos,publish_stream'}); } But this causes the entire page to refresh and is not 'elegant' per se...

  • c++ multithread array

    - by user1731972
    i'm doing something for fun, trying to learn multithreading Problems passing array by reference to threads but Arno pointed out that my threading via process.h wasn't going to be multi-threaded. What I'm hoping to do is something where I have an array of 100 (or 10,000, doesn't really matter I don't think), and split up the assignment of values to each thread. Example, 4 threads = 250 values per thread to be assigned. Then I can use this filled array for further calculations. Here's some code I was working on (which doesn't work) #include <process.h> #include <windows.h> #include <iostream> #include <fstream> #include <time.h> //#include <thread> using namespace std; void myThread (void *dummy ); CRITICAL_SECTION cs1,cs2; // global int main() { ofstream myfile; myfile.open ("coinToss.csv"); int rNum; long numRuns; long count = 0; int divisor = 1; float holder = 0; int counter = 0; float percent = 0.0; HANDLE hThread[1000]; int array[10000]; srand ( time(NULL) ); printf ("Runs (use multiple of 10)? "); cin >> numRuns; for (int i = 0; i < numRuns; i++) { //_beginthread( myThread, 0, (void *) (array1) ); //??? //hThread[i * 2] = _beginthread( myThread, 0, (void *) (array1) ); hThread[i*2] = _beginthread( myThread, 0, (void *) (array) ); } //WaitForMultipleObjects(numRuns * 2, hThread, TRUE, INFINITE); WaitForMultipleObjects(numRuns, hThread, TRUE, INFINITE); } void myThread (void *param ) { //thanks goes to stockoverflow //http://stackoverflow.com/questions/12801862/problems-passing-array-by-reference-to-threads int *i = (int *)param; for (int x = 0; x < 1000000; x++) { //param[x] = rand() % 2 + 1; i[x] = rand() % 2 + 1; } } Can anyone explain why it isn't working?

  • Why is .NET Post different from CURL? broken?

    - by ironnailpiercethesky
    I dont understand this. I ran this code below and the result json string was the link is expired (meaning invalid). However the curl code does the exact same thing and works. I either get the expected string with the url or it says i need to wait (for a few seconds to 1 minute). Why? whats the difference between the two? It looks very F%^&*ed up that it is behaving differently (its been causing me HOURS of problems). NOTE: the only cookie required by the site is SID (tested). It holds your session id. The first post activates it and the 2nd command checks the status with the returning json string. Feel free to set the CookieContainer to only use SID if you like. WARNING: you may want to change SID to a different value so other people arent activating it. Your may want to run the 2nd url to ensure the session id is not used and says expired/invalid before you start. additional note: with curl or in your browser if you do the POST command you can stick the sid in .NET cookie container and the 2nd command will work. But doing the first command (the POST data) will not work. This post function i have used for many other sites that require post and so far it has worked. Obviously checking the Method is a big deal and i see it is indeed POST when doing the first command. static void Main(string[] args) { var cookie = new CookieContainer(); PostData("http://uploading.com/files/get/37e36ed8/", "action=second_page&file_id=9134949&code=37e36ed8", cookie); Thread.Sleep(4000); var res = PostData("http://uploading.com/files/get/?JsHttpRequest=12719362769080-xml&action=get_link&file_id=9134949&code=37e36ed8&pass=undefined", null/*this makes it GET*/, cookie); Console.WriteLine(res); /* curl -b "SID=37468830" -A "DUMMY_User_Aggent" -d "action=second_page&file_id=9134949&code=37e36ed8" "http://uploading.com/files/get/37e36ed8/" curl -b "SID=37468830" -A "DUMMY_User_Aggent" "http://uploading.com/files/get/?JsHttpRequest=12719362769080-xml&action=get_link&file_id=9134949&code=37e36ed8&pass=undefined" */ }

  • Regular expression Not working properly n case of multiple trailing ]]]]

    - by ronan
    I have the requirement that in a textbox a user can jump to the next word enclosed in [] on a tab out for example Hi [this] is [an] example. Testing [this] So when my cursor is at Hi and I do a tab out , the characters enclosed in the [this] are highlighted and when I again do a tabl out th next characters enclosed in following [an] are highlighted. This works fine Now the requirement is whatever the text including the special chars between [] needs to be highlighted case 1: when I have trailing ]]], it only highlights leading [[[ and ignores ]]]] e.g case 2: In case of multiple trailing ] e.e [this]]]] is [test], ideally one a single tabl out from this , it should go to next text enclosed in [] but a user has to tab out 4 times one tab per training ] to go to next [text] strong text The code is $(document).ready(function() { $('textarea').highlightTextarea({ color : '#0475D1', words : [ "/(\[.*?\])/g" ], textColor : '#000000' }); $('textarea').live('keydown', function(e) { var keyCode = e.keyCode || e.which; if (keyCode == 9) { var currentIndex = getCaret($(this).get(0)) selectText($(this), currentIndex); return false; } }); }); function selectText(element, currentIndex) { var rSearchTerm = new RegExp(/(\[.*?\])/); var ind = element.val().substr(currentIndex).search(rSearchTerm) currentIndex = (ind == -1 ? 0 : currentIndex); ind = (ind == -1 ? element.val().search(rSearchTerm) : ind); currentIndex = (ind == -1 ? 0 : currentIndex); var lasInd = (element.val().substr(currentIndex).search(rSearchTerm) == -1 ? 0 : element.val().substr(currentIndex).indexOf(']')); var input = element.get(0); if (input.setSelectionRange) { input.focus(); input.setSelectionRange(ind + currentIndex, lasInd + 1 + currentIndex); } else if (input.createTextRange) { var range = input.createTextRange(); range.collapse(true); range.moveEnd('character', lasInd + 1 + currentIndex); range.moveStart('character', ind + currentIndex); range.select(); } } function getCaret(el) { if (el.selectionEnd) { return el.selectionEnd; } else if (document.selection) { el.focus(); var r = document.selection.createRange(); if (r == null) { return 0; } var re = el.createTextRange(), rc = re.duplicate(); re.moveToBookmark(r.getBookmark()); rc.setEndPoint('EndToStart', re); return rc.text.length; } return 0; } Please let me know to handle two above cases

    Hello, I have a strange wird problem with a trigger: I set up a trigger for update other tables after an insert in a table.

  • Exception from Response.Redirect?

    - by allencoded
    I keep getting an error: A first chance exception of type 'System.Threading.ThreadAbortException' occurred in mscorlib.dll An exception of type 'System.Threading.ThreadAbortException' occurred in mscorlib.dll but was not handled in user code The thread '' (0x27ee4) has exited with code 0 (0x0). I was told it was related to this: protected void Button1_Click(object sender, EventArgs e) { Response.Redirect("Results.aspx?Keywords=" + searchString.Text); } I figured it may help to include my complete code. The code above is the only C# code on my first asp page. That code relates to this code on this page. It is also the only C# code I have on my second page. I am simply just trying to pass a keyword from a search form to this block of code: if (Request.QueryString["Keywords"] != null){ string keywords = Request.QueryString["Keywords"]; string myAppID = "HIDDEN"; var xml = XDocument.Load("http://svcs.ebay.com/services/search/FindingService/v1?OPERATION-NAME=findItemsByKeywords&SERVICE-VERSION=1.0.0&SECURITY-APPNAME=" + myAppID + "&RESPONSE-DATA-FORMAT=XML&REST-PAYLOAD&keywords=" + keywords + "&paginationInput.entriesPerPage=5"); XNamespace ns = "http://www.ebay.com/marketplace/search/v1/services"; var titles = from item in xml.Root.Descendants(ns + "title") select new{ title = xml.Descendants(ns + "title").Select (x => x.Value), }; foreach (var item in titles){ Label1.Text += item; } } This block of code calls the keyword value and uses it in an api to perform a search. The code of the xml(api) formats like this: <findItemsByKeywordsResponse xmlns="http://www.ebay.com/marketplace/search/v1/services"> <searchReslut count="5"> <item> <title></title> </item> <item> <title></title> </item> <item> <title></title> </item> Why am I getting this error how do you fix it?

  • probelm with recv() on a tcp connection

    - by michael
    Hi, I am simulating TCP communication on windows in C I have sender and a receiver communicating. sender sends packets of specific size to receiver. receiver gets them and send an ACK for each packet it received back to the sender. If the sender didn't get a specific packet (they are numbered in a header inside the packet) it sends the packet again to the receiver. Here is the getPacket function on the receiver side: //get the next packet from the socket. set the packetSize to -1 //if it's the first packet. //return: total bytes read // return: 0 if socket has shutdown on sender side, -1 error, else number of bytes received int getPakcet(char *chunkBuff,int packetSize,SOCKET AcceptSocket){ int totalChunkLen = 0; int bytesRecv=-1; bool firstTime=false; if (packetSize==-1) { packetSize=MAX_PACKET_LENGTH; firstTime=true; } int needToGet=packetSize; do { char* recvBuff; recvBuff = (char*)calloc(needToGet,sizeof(char)); if(recvBuff == NULL){ fprintf(stderr,"Memory allocation problem\n"); return -1; } bytesRecv = recv(AcceptSocket, recvBuff, needToGet, 0); if (bytesRecv == SOCKET_ERROR){ fprintf(stderr,"recv() error %ld.\n", WSAGetLastError()); totalChunkLen=-1; return -1; } if (bytesRecv == 0){ fprintf(stderr,"recv(): socket has shutdown on sender side"); return 0; } else if(bytesRecv > 0) { memcpy(chunkBuff + totalChunkLen,recvBuff,bytesRecv); totalChunkLen+=bytesRecv; } needToGet-=bytesRecv; } while ((totalChunkLen < packetSize) && (!firstTime)); return totalChunkLen; } i use firstTime because for the first time the receiver doesn't know the normal package size that the sender is going to send to it, so i use a MAX_PACKET_LENGTH to get a package and then set the normal package size to the num of bytes i have received my problem is the last package. it's size is less than the package size so lets say last package size is 2 and the normal package size is 4. so recv() gets two bytes, continues to the while condition, then totalChunkLen < packetSize because 2<4 so it iterates the loop again and the gets stuck in recv() because it's blocking because the sender has nothing to send. on the sender side i can't close the connection because i didn't ACK back, so it's kind of a deadlock. receiver is stuck because it's waiting for more packages but sender has nothing to send. i don't want to use a timeout for recv() or to insert a special character to the package header to mark that it is the last one what can i do ? thanks

  • Can't record or play with a simple recorder?

    - by user1280535
    I have 2 classes, a record and a player. In my main scene, I create an instance of them and play and record. But, as I see, it only records and somehow does not play (the file is not there!) Here is the code for both : -(void)record { NSArray *dirPaths; NSString *docsDir; NSString *sound= @"sound0.caf" ; dirPaths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) ; docsDir = [dirPaths objectAtIndex:0]; NSString *soundFilePath = [docsDir stringByAppendingPathComponent:sound]; NSURL *soundFileURL = [NSURL fileURLWithPath:soundFilePath]; NSDictionary *settings = [NSDictionary dictionaryWithObjectsAndKeys: [NSNumber numberWithFloat: 44100.0], AVSampleRateKey, [NSNumber numberWithInt: kAudioFormatAppleLossless], AVFormatIDKey, [NSNumber numberWithInt: 1], AVNumberOfChannelsKey, [NSNumber numberWithInt: AVAudioQualityMax], AVEncoderAudioQualityKey, nil]; NSError *error; myRecorder = [[AVAudioRecorder alloc] initWithURL:soundFileURL settings:settings error:&error]; if (myRecorder) { NSLog(@"rec"); [myRecorder prepareToRecord]; myRecorder.meteringEnabled = YES; [myRecorder record]; } else NSLog( @"error" ); } I can see the log of rec. -(void)play { NSArray *dirPaths; NSString *docsDir; dirPaths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES); docsDir = [dirPaths objectAtIndex:0]; NSString *soundFilePath1 = @"sound0.caf" ; NSURL *soundFileURL = [NSURL fileURLWithPath:soundFilePath1]; BOOL isMyFileThere = [[NSFileManager defaultManager] fileExistsAtPath:soundFilePath1]; if(isMyFileThere) { NSLog(@"PLAY"); avPlayer1 = [[AVAudioPlayer alloc] initWithContentsOfURL:soundFileURL error:NULL]; avPlayer1.volume = 8.0; avPlayer1.delegate = self; [avPlayer1 play]; } } I DONT SEE THE LOG OF PLAY ! I call them both with: recInst=[recorder alloc]; //to rec [recInst record]; plyInst=[player alloc]; //play [plyInst play]; and to stop the recorder: - (void)stopRecorder { NSLog(@"stopRecordings"); [myRecorder stop]; //[myRecorder release]; } What's wrong here?

  • IE not showing jquery append() images

    - by Johannes Ruuska
    Ok, so i took John Raasch's slideshow script and modyfied it too dynamicly fetch images from folders on the server through ajax. The slideshow work like a charm in FF and Chrome but IE is not showing the images. And since IE's javascript debugging possibilities is close to none I cant figure out what is crashing. Javascript (indenting got messed up when pasting here but you get the code anyway): function slideSwitch() { var $active = $('#box_bildspel IMG.active'); if ( $active.length == 0 ) $active = $('#box_bildspel IMG:last'); var $next = $active.next().length ? $active.next() : $('#box_bildspel IMG:first'); $active.addClass('last-active'); $next.css({opacity: 0.0}) .addClass('active') .animate({opacity: 1.0}, 1000, function() { $active.removeClass('active last-active'); }); } $(document).ready(function(){ $.get('includes/bildspel.php?page='+page, function(r){ var file = r.split('!'); var path = 'pic/bildspel/'+page+'/'; var data = ''; if(file != null && file != ''){ $.each(file, function(key, value){ if(key == 0) { $('#box_bildspel').append('<img src="'+path+value+'" class="active"></img>'); //console.log(path+value); } else { $('#box_bildspel').append('<img src="'+path+value+'"></img>'); //console.log(path+value); } }); } if(file.length > 1){ $(function() { setInterval( "slideSwitch()", 4000 ); }); } }); }); PHP: <?php function getimgs($page) { $path = '../pic/bildspel/'.$page; $files = ''; if ($handle = opendir($path)) { while (false !== ($file = readdir($handle))) { if ($file !== '.' && $file !== '..') { $files .= $file.'!'; } } closedir($handle); echo substr_replace($files ,"",-1);; } } getimgs($_GET['page']); ?> Tested in IE 7 & 8 Any ideas? I have a deadline on this site for tomorrow (april 23) would appreciate VERY much if someone could figure this on out for me, thanks in advance!

  • OutOfMemoryError loading Bitmap via DefaultHttpClient

    - by Goddchen
    i have a simple problem: Although i'm using sampleSize properly, my code doesn't even reach the BitmapFactorycode, since DefaultHttpClient is already throwing the exception. Here is my code: DefaultHttpClient client = new DefaultHttpClient(); HttpGet request = new HttpGet(mSongInfo.imageLarge); HttpResponse response = client.execute(request); int sampleSize = 1; while (response.getEntity().getContentLength() / sampleSize / sampleSize > 100 * 1024) { sampleSize *= 2; } BitmapFactory.Options options = new BitmapFactory.Options(); options.inSampleSize = sampleSize; final Bitmap bitmap = BitmapFactory.decodeStream(response .getEntity().getContent(), null, options); And here is the exception: 0 java.lang.OutOfMemoryError: (Heap Size=11463KB, Allocated=7623KB, Bitmap Size=9382KB) 1 at org.apache.http.util.ByteArrayBuffer.<init>(ByteArrayBuffer.java:53) 2 at org.apache.http.impl.io.AbstractSessionInputBuffer.init(AbstractSessionInputBuffer.java:82) 3 at org.apache.http.impl.io.SocketInputBuffer.<init>(SocketInputBuffer.java:98) 4 at org.apache.http.impl.SocketHttpClientConnection.createSessionInputBuffer(SocketHttpClientConnection.java:83) 5 at org.apache.http.impl.conn.DefaultClientConnection.createSessionInputBuffer(DefaultClientConnection.java:170) 6 at org.apache.http.impl.SocketHttpClientConnection.bind(SocketHttpClientConnection.java:106) 7 at org.apache.http.impl.conn.DefaultClientConnection.openCompleted(DefaultClientConnection.java:129) 8 at org.apache.http.impl.conn.DefaultClientConnectionOperator.openConnection(DefaultClientConnectionOperator.java:173) 9 at org.apache.http.impl.conn.AbstractPoolEntry.open(AbstractPoolEntry.java:164) 10 at org.apache.http.impl.conn.AbstractPooledConnAdapter.open(AbstractPooledConnAdapter.java:119) 11 at org.apache.http.impl.client.DefaultRequestDirector.execute(DefaultRequestDirector.java:359) 12 at org.apache.http.impl.client.AbstractHttpClient.execute(AbstractHttpClient.java:555) 13 at org.apache.http.impl.client.AbstractHttpClient.execute(AbstractHttpClient.java:487) 14 at org.apache.http.impl.client.AbstractHttpClient.execute(AbstractHttpClient.java:465) 15 at de.goddchen.android.easysongfinder.fragments.SongFragment$1.run(SongFragment.java:79) 16 at java.lang.Thread.run(Thread.java:1027) As you can see, the code doesn't even reach the part where i check the size (Content-Length) of the image and calculate a proper sample size. I wasn't aware that simply calling DefaultHttpClient.execute(...) will already load the complete content into the memory. Am i doing something wrong? What is the right way to first retrieve the content length and then start reading the content from an InputStream? EDIT To avoid common answers that show how to load images from a URL: i already know how to do that, i have also posted the code above, so why do you keep referencing tutorials on that? I explicitly was very clear about the problem: Why is HttpClient.execute(...)already fetching the whole content and storing it in memory instead of providing a proper ÌnputStreamto me? Please don't post any beginner tutorials on how to load aBitmap`from a URL...

  • Can't access Elements previously created by innerHTML with Javascript/Prototype

    - by Joe Hopfgartner
    I am setting the innerHTML variable of a div with contents from an ajax request: new Ajax.Request('/search/ajax/allakas/?ext_id='+extid, { method:'get', onSuccess: function(transport){ var response = transport.responseText || "no response text"; $('admincovers_content').innerHTML=response; }, onFailure: function(){ alert('Something went wrong...') } }); The response text cotains a form: <form id="akas-admin" method="post" action="/search/ajax/modifyakas/"> <input type="text" name="formfield" value="i am a form field"/> </form> Then I call a functiont that should submit that form: $('akas-admin').request({ onComplete: function(transport){ //alert('Form data saved! '+transport.responseText) $('admincovers_content').innerHTML=transport.responseText; } }); The problem is $('akas-admin) returns null , I tried to put the form with this id in the original document, which works. Question: Can I somehow "revalidate" the dom or access elements that have been inserted with innerHTML? Edit Info: document.getElementById("akas-admin").submit() works just fine, problem is i don't want to reload the whole page but post the form over ajax and get the response text in a callback function. Edit: Based on the answers provided, i replaced my function that does the request with the following observer: Event.observe(document.body, 'click', function(event) { var e = Event.element(event); if ('aka-savelink' == e.identify()) { alert('savelink clicked!'); if (el = e.findElement('#akas-admin')) { alert('found form to submit it has id: '+el.identify()); el.request({ onComplete: function(transport){ alert('Form data saved! '+transport.responseText) $('admincovers_content').innerHTML=transport.responseText; } }); } } }); problem is that i get as far as alert('savelink clicked!'); . findelement doesnt return the form. i tried to place the save link above and under the form. both doesnt work. i also think this approach is a bit clumsy and i am doing it wrong. could anyone point me in the right direction?

  • Code to generate random numbers in C++

    - by user1678927
    Basically I have to write a program to generate random numbers to simulate the rolling of a pair of dice. This program should be constructed in multiple files. The main function should be in one file, the other functions should be in a second source file, and their prototypes should be in a header file. First I write a short function that returns a random value between 1 and 6 to simulate the rolling of a single 6-sided die.Second, i write a function that pretends to roll a pair of dice by calling this function twice. My program starts by asking the user how many rolls should be made. Then I write a function to simulate rolling the dice this many times, keeping a count of exactly how many times the values 2,3,4,5,6,7,8,9,10,11,12(each number is the sum of a pair of dice) occur in an array. Later I write a function to display a small bar chart using these counts that ideally would look something like below for a sample of 144 rolls, where the number of asterisks printed corresponds to the count: 2 3 4 5 6 7 8 9 10 11 12 * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * Next, to see how well the random number generator is doing, I write a function to compute the average value rolled. Compare this to the ideal average of 7. Also, print out a small table showing the counts of each roll made by the program, the ideal count based on the frequencies above given the total number of rolls, and the difference between these values in separate columns. This is my incomplete code so far: "Compiler visual studio 2010" int rolling(){ //Function that returns a random value between 1 and 6 rand(unsigned(time(NULL))); int dice = 1 + (rand() %6); return dice; } int roll_dice(int num1,int num2){ //it calls 'rolling function' twice int result1,result2; num1 = rolling(); num2 = rolling(); result1 = num1; result2 = num2; return result1,result2; } int main(void){ int times,i,sum,n1,n2; int c1,c2,c3,c4,c5,c6,c7,c8,c9,c10,c11;//counters for each sum printf("Please enter how many times you want to roll the dice.\n") scanf_s("%i",&times); I pretend to use counters to count each sum and store the number(the count) in an array. I know i need a loop (for) and some conditional statements (if) but m main problem is to get the values from roll_dice and store them in n1 and n2 so then i can sum them up and store the sum in 'sum'.

  • No Change for Index of DropDownList in a Custom Control!!!

Here Is My ASCX file Behind Code: private int _selectedCategoryId; private bool _autoPostback = false; public event EventHandler SelectedIndexChanged; public void BindData() { //Some Code... } protected void Page_Load(object sender, EventArgs e) { BindData(); DropDownList1.AutoPostBack = this._autoPostback; } public int SelectedCategoryId { get { return int.Parse(this.DropDownList1.SelectedItem.Value); } set { this._selectedCategoryId = value; } } public string AutoPostback { get { return this.DropDownList1.AutoPostBack.ToString(); } set { this._autoPostback = Convert.ToBoolean(value); } } protected void DropDownList1_SelectedIndexChanged(object sender, EventArgs e) { if (SelectedIndexChanged != null) SelectedIndexChanged(this, EventArgs.Empty); } I Want Used Update Panel to Update Textbox Fields According to dorp down list selected index. this is my code in ASPX page: <asp:Panel ID="PanelCategory" runat="server"> <p> Select Product Category:&nbsp; <myCtrl:CategoryDDL ID="CategoryDDL1" AutoPostback="true" OnSelectedIndexChanged="CategoryIndexChanged" SelectedCategoryId="0" runat="server" /> </p> <hr /> </asp:Panel> <asp:UpdatePanel ID="UpdatePanelEdit" runat="server"> <ContentTemplate> <%--Some TextBoxes and Other Controls--%> </ContentTemplate> <Triggers> <asp:PostBackTrigger ControlID="CategoryDDL1" /> </Triggers> </asp:UpdatePanel> But Always The Selected Index of CategoryDDL1 is 0(Like default). this means Only Zero Value will pass to the event to update textboxes Data. what is the wrong with my code? why the selected Index not Changing?
