  • Customer Attribute, not sorting select options

    - by Bosworth99
    Made a module that creates some customer EAV attributes. One of these attributes is a Select, and I'm dropping a bunch of options into their respective tables. Everything lines up and is accessible on both the front end and the back. Last thing before calling this part of things finished is the sort order of the options. They come out all scrambled, instead of the obvious default or alphabetical (seemingly at random... very wierd). I'm on Mage v1.11 (Pro/Enterprise). config.xml <config> <modules> <WACI_CustomerAttr> <version>0.1.0</version> </WACI_CustomerAttr> </modules> <global> <resources> <customerattr_setup> <setup> <module>WACI_CustomerAttr</module> <class>Mage_Customer_Model_Entity_Setup</class> </setup> <connection> <use>core_setup</use> </connection> </customerattr_setup> </resources> <models> <WACI_CustomerAttr> <class>WACI_CustomerAttr_Model</class> </WACI_CustomerAttr> </models> <fieldsets> <customer_account> <agency><create>1</create><update>1</update></agency> <title><create>1</create><update>1</update></title> <phone><create>1</create><update>1</update></phone> <mailing_address><create>1</create><update>1</update></mailing_address> <city><create>1</create><update>1</update></city> <state><create>1</create><update>1</update></state> <zip><create>1</create><update>1</update></zip> <fed_id><create>1</create><update>1</update></fed_id> <ubi><create>1</create><update>1</update></ubi> </customer_account> </fieldsets> </global> </config> mysql4-install-0.1.0.php <?php Mage::log('Installing WACI_CustomerAttr'); echo 'Running Upgrade: '.get_class($this)."\n <br /> \n"; //die ( 'its running' ); $installer = $this; /* @var $installer Mage_Customer_Model_Entity_Setup */ $installer->startSetup(); // bunch of attributes // State $installer->addAttribute('customer','state', array( 'type' => 'varchar', 'group' => 'Default', 'label' => 'State', 'input' => 'select', 'default' => 'Washington', 'source' => 'WACI_CustomerAttr/customer_attribute_data_select', 'global' => Mage_Catalog_Model_Resource_Eav_Attribute::SCOPE_STORE, 'required' => true, 'visible' => true, 'user_defined' => 1, 'position' => 67 ) ); $attrS = Mage::getSingleton('eav/config')->getAttribute('customer', 'state'); $attrS->addData(array('sort_order'=>67)); $attrS->setData('used_in_forms', array('adminhtml_customer','customer_account_edit','customer_account_create'))->save(); $state_list = array('Alabama','Alaska','Arizona','Arkansas','California','Colorado','Connecticut','Delaware','Florida','Georgia', 'Hawaii','Idaho','Illinois','Indiana','Iowa','Kansas','Kentucky','Louisiana','Maine','Maryland','Massachusetts','Michigan', 'Minnesota','Mississippi','Missouri','Montana','Nebraska','Nevada','New Hampshire','New Jersey','New Mexico','New York', 'North Carolina','North Dakota','Ohio','Oklahoma','Oregon','Pennsylvania','Rhode Island','South Carolina','South Dakota', 'Tennessee','Texas','Utah','Vermont','Virginia','Washington','West Virginia','Wisconsin','Wyoming'); $aOption = array(); $aOption['attribute_id'] = $installer->getAttributeId('customer', 'state'); for($iCount=0;$iCount<sizeof($state_list);$iCount++){ $aOption['value']['option'.$iCount][0] = $state_list[$iCount]; } $installer->addAttributeOption($aOption); // a few more $installer->endSetup(); app/code/local/WACI/CustomerAttr/Model/Customer/Attribute/Data/Select.php <?php class WACI_CustomerAttr_Model_Customer_Attribute_Data_Select extends Mage_Eav_Model_Entity_Attribute_Source_Abstract{ function getAllOptions(){ if (is_null($this->_options)) { $this->_options = Mage::getResourceModel('eav/entity_attribute_option_collection') ->setAttributeFilter($this->getAttribute()->getId()) ->setStoreFilter($this->getAttribute()->getStoreId()) ->setPositionOrder('asc') ->load() ->toOptionArray(); } $options = $this->_options; return $options; } } theme/variation/template/persistent/customer/form/register.phtml <li> <?php $attribute = Mage::getModel('eav/config')->getAttribute('customer','state'); ?> <label for="state" class="<?php if($attribute->getIsRequired() == true){?>required<?php } ?>"><?php if($attribute->getIsRequired() == true){?><em>*</em><?php } ?><?php echo $this->__('State') ?></label> <div class="input-box"> <select name="state" id="state" class="<?php if($attribute->getIsRequired() == true){?>required-entry<?php } ?>"> <?php $options = $attribute->getSource()->getAllOptions(); foreach($options as $option){ ?> <option value='<?php echo $option['value']?>' <?php if($this->getFormData()->getState() == $option['value']){ echo 'selected="selected"';}?>><?php echo $this->__($option['label'])?></option> <?php } ?> </select> </div> </li> All options are getting loaded into table eav_attribute_option just fine (albeit without a sort_order defined), as well as table eav_attribute_option_value. In the adminhtml / customer-manage customers-account information this select is showing up fine (but its delivered automatically by the system). Seems I should be able to set the sort-order on creation of the attributeOptions, or, certainly, define the sort order in the data/select class. But nothing I've tried works. I'd rather not do a front-end hack either... Oh, and how do I set the default value of this select? (Different question, I know, but related). Setting the attributes 'default' = 'washington' seems to do nothing. There seem to be a lot of ways to set up attribute select options like this. Is there a better way that the one I've outlined here? Perhaps I'm messing something up. Cheers

  • ArrayList access

    - by Ricky McQuesten
    So once again I have a question about this program. I want to store transactions that are made in an arraylist and then have an option in the case menu where I can print out those that are stored. I have been researching online and have been unable to find a solution to this, so is this possible and how would I go about doing this? I also want to attach a timestamp to each transaction as well. Here is the code I have so far. So my question is how would I add a timestamp to each withdrawal or deposit, and how would I store each transaction in array list? import java.util.*; public class BankAccount extends Money { //inheritence static String name; public static int acctNum; public static double balance, amount; BankAccount(String name, int accNo, double bal) { this.name = name; this.acctNum = accNo; this.balance = bal; } void display() { System.out.println("Your Name:" + name); System.out.println("Your Account Number:" + acctNum); System.out.println("Your Current Account Balance:" + Money.getBalance()); } void displayBalance() { System.out.println("Balance:" + balance); } } import java.util.Scanner; /** * * @author Ricky */ public class Money { public static int accountNumber; public static double balance; static double amount; static String name; public void setDeposit(double amount) { balance = balance + amount; if (amount < 0) { System.out.println("Invalid"); } } public double getDeposit() { return 1; } public void setBalance(double b) { balance = b; } public static double getBalance() { return balance; } public void setWithdraw(double amount) { if (balance < amount) { System.out.println("Not enough funds."); } else if(amount < 0) { System.out.println("Invalid"); } else { balance = balance - amount; } } public double getWithdraw() { return 1; } } import java.util.*; public class Client { public static void main(String args[]) { int n = 0; int count; String trans; ArrayList<String> transaction= new ArrayList<String>(n); Scanner input = new Scanner(System.in); System.out.println("Welcome to First National Bank"); System.out.println("Please enter your name: "); String cusName = input.nextLine(); System.out.println("You will now be assigned an account number."); Random randomGenerator = new Random(); int accNo = randomGenerator.nextInt(100000); //random number System.out.println("Your account number is: " + accNo); System.out.println("Please enter your initial account balance: "); Double balance = input.nextDouble(); BankAccount b1 = new BankAccount(cusName, accNo, balance); b1.setBalance(balance); int menu; /*System.out.println("Menu"); System.out.println("1. Deposit Amount"); System.out.println("2. Withdraw Amount"); System.out.println("3. Display Information"); System.out.println("4. Exit");*/ boolean quit = false; do { System.out.println("*******Menu*******"); System.out.println("1. Deposit Amount"); // menu to take input from user System.out.println("2. Withdraw Amount"); System.out.println("3. Display Information"); System.out.println("4. Exit"); System.out.print("Please enter your choice: "); menu = input.nextInt(); switch (menu) { case 1: System.out.print("Enter depost amount:"); b1.setDeposit(input.nextDouble()); b1.getDeposit(); transaction.add(trans); break; case 2: System.out.println("Current Account Balance=" + b1.getBalance()); System.out.print("Enter withdrawal amount:"); b1.setWithdraw(input.nextDouble()); b1.getWithdraw(); transaction.add(trans); break; // switch statments to do a loop case 3: b1.display(); break; case 4: quit = true; break; } } while (!quit); } } public class Date { static Date time = new Date(); }

  • Pointers to Derived Class Objects Losing vfptr

    - by duckworthd
    To begin, I am trying to write a run-of-the-mill, simple Ray Tracer. In my Ray Tracer, I have multiple types of geometries in the world, all derived from a base class called "SceneObject". I've included the header for it here. /** Interface for all objects that will appear in a scene */ class SceneObject { public: mat4 M, M_inv; Color c; SceneObject(); ~SceneObject(); /** The transformation matrix to be applied to all points of this object. Identity leaves the object in world frame. */ void setMatrix(mat4 M); void setMatrix(MatrixStack mStack); void getMatrix(mat4& M); /** The color of the object */ void setColor(Color c); void getColor(Color& c); /** Alter one portion of the color, leaving the rest as they were. */ void setDiffuse(vec3 rgb); void setSpecular(vec3 rgb); void setEmission(vec3 rgb); void setAmbient(vec3 rgb); void setShininess(double s); /** Fills 'inter' with information regarding an intersection between this object and 'ray'. Ray should be in world frame. */ virtual void intersect(Intersection& inter, Ray ray) = 0; /** Returns a copy of this SceneObject */ virtual SceneObject* clone() = 0; /** Print information regarding this SceneObject for debugging */ virtual void print() = 0; }; As you can see, I've included a couple virtual functions to be implemented elsewhere. In this case, I have only two derived class -- Sphere and Triangle, both of which implement the missing member functions. Finally, I have a Parser class, which is full of static methods that do the actual "Ray Tracing" part. Here's a couple snippets for relevant portions void Parser::trace(Camera cam, Scene scene, string outputFile, int maxDepth) { int width = cam.getNumXPixels(); int height = cam.getNumYPixels(); vector<vector<vec3>> colors; colors.clear(); for (int i = 0; i< width; i++) { vector<vec3> ys; for (int j = 0; j<height; j++) { Intersection intrsct; Ray ray; cam.getRay(ray, i, j); vec3 color; printf("Obtaining color for Ray[%d,%d]\n", i,j); getColor(color, scene, ray, maxDepth); ys.push_back(color); } colors.push_back(ys); } printImage(colors, width, height, outputFile); } void Parser::getColor(vec3& color, Scene scene, Ray ray, int numBounces) { Intersection inter; scene.intersect(inter,ray); if(inter.isIntersecting()){ Color c; inter.getColor(c); c.getAmbient(color); } else { color = vec3(0,0,0); } } Right now, I've forgone the true Ray Tracing part and instead simply return the color of the first object hit, if any. As you have no doubt noticed, the only way the computer knows that a ray has intersected an object is through Scene.intersect(), which I also include. void Scene::intersect(Intersection& i, Ray r) { Intersection result; result.setDistance(numeric_limits<double>::infinity()); result.setIsIntersecting(false); double oldDist; result.getDistance(oldDist); /* Cycle through all objects, making result the closest one */ for(int ind=0; ind<objects.size(); ind++){ SceneObject* thisObj = objects[ind]; Intersection betterIntersect; thisObj->intersect(betterIntersect, r); double newDist; betterIntersect.getDistance(newDist); if (newDist < oldDist){ result = betterIntersect; oldDist = newDist; } } i = result; } Alright, now for the problem. I begin by creating a scene and filling it with objects outside of the Parser::trace() method. Now for some odd reason, I cast Ray for i=j=0 and everything works wonderfully. However, by the time the second ray is cast all of the objects stored in my Scene no longer recognize their vfptr's! I stepped through the code with a debugger and found that the information to all the vfptr's are lost somewhere between the end of getColor() and the continuation of the loop. However, if I change the arguments of getColor() to use a Scene& instead of a Scene, then no loss occurs. What crazy voodoo is this?

  • How do I name an array key with a key inside the array

    - by Confused
    I have some data, yes, data. This data came from a MySQL query and it will always contain 4 items, always. I want to cache that data in an array table for use later within a web page but I want to keep the keys from the query and separate out each grouping within a multidimensional array. However to save time iterating through the array each time I want to find a given group of data, I want to call the keys of the first array the same as the ID key which is always the first key within each four items. At the minute I'm using this code: function mysql_fetch_full_result_array($result) { $table_result=array(); $r=0; while($row = mysql_fetch_assoc($result)){ $arr_row=array(); $c=0; while ($c < mysql_num_fields($result)) { $col = mysql_fetch_field($result, $c); $arr_row[$col -> name] = $row[$col -> name]; $c++; } $table_result[$r] = $arr_row; $r++; } return $table_result; } I'm currently testing this using 3 unique users, so I'm getting three rows back from the query and the data from this function ends up in the format: [0]=> . . [id] => 1 . . [name] => random name . . [tel] => random tel . . [post] => post code data [1]=> . . [id] => 34 . . [name] => random name . . [tel] => random tel . . [post] => post code data [2]=> . . [id] => 56 . . [name] => random name . . [tel] => random tel . . [post] => post code data So how do I alter the code to instead of the keys [0], [1], [2] give me the output: [1]=> . . [id] => 1 . . [name] => random name . . [tel] => random tel . . [post] => post code data [34]=> . . [id] => 34 . . [name] => random name . . [tel] => random tel . . [post] => post code data [56]=> . . [id] => 56 . . [name] => random name . . [tel] => random tel . . [post] => post code data I don't mind if the main array keys are strings of numbers rather than numbers but I'm a bit stuck, I tried changing the $table_result[$r] = $arr_row; part to read $table_result[$result['id']] = $arr_row; but that just outputs an array of one person. I know I need another loop but I'm struggling to work out how to write it.

  • $_GET['page'] loading content incorrectly

    - by s32ialx
    OK so here is my previous post PHP Templated Site w/ file_get_content links now i got that issue resolved BUT the problem is now that the content loads it displays UNDER the div i placed #CONTENT# inside so the styles are being ignored and it's posting #CONTENT# outside the divs at positions 0,0 any suggestions? Found out whats happening by using "View Source" seems that it's putting all of the #CONTENT#, content that's being loaded in front of the tag. Like this <doctype...> <div class="home"> blah blah </div> <head> <script src=""></script> </head> <body> <div class="header"></div> <div class="contents"> #CONTENT# < where content SHOULD load </div> <div class="footer"></div> </body> so anyone got a fix? OK so a better description I'll add relevant screen-shots Whats happening is /* file.class.php */ <?php $file = new file(); class file{ var $path = "templates/clean"; var $ext = "tpl"; function loadfile($filename){ return file_get_contents($this->path . "/" . $filename . "." . $this->ext); } function css($val,$content='',$contentvar='#CSS#') { if(is_array($val)) { $css = 'style="'; foreach($val as $p) { $css .= $p . ";"; } $css .= '"'; } else { $css = 'style="' . $val . '"'; } if($content!='') { return str_replace($contentvar,' ' . $css,$content); } else { return $css; } } function setsize($content,$width='-1',$height='-1',$border='-1'){ $css = ''; if($width!='-1') { $css = $css . "width=\"".$width."\""; } if($height!='-1') { $css = $css . "height=\"".$height."\""; } if($border!='-1') { $css = $css . "border=\"" . $border . "\""; } return str_replace('#SIZE#',' ' . $css,$content); } function setcontent($content,$newcontent,$vartoreplace='#CONTENT#'){ $val = str_replace($vartoreplace,$newcontent,$content); return $val; } function p($content) { $v = $content; $v = str_replace('#CONTENT#','',$v); $v = str_replace('#SIZE#','',$v); print $v; } } if (isset($_GET['page'])) { $content = $_GET['page'].'.php'; } else { $content = 'main.php'; } ?> is calling for a file_get_contents at the bottom which I use in /* index.php */ <?php include('classes/file.class.php'); // load the templates $header = $file->loadfile('header'); $body = $file->loadfile('body'); $footer = $file->loadfile('footer'); // fill body.tpl #CONTENT# slot with $content $body = $file->setcontent($body, $content); // cleanup and output the full page $file->p($header . $body . $footer); ?> and loads into /* body.tpl */ <div id="bodys"> <div id="bodt"></div> <div id="bodm"> <div id="contents"> #CONTENT# </div> </div> <div id="bodb"></div> </div> but the issue is as follows the $content loads properly img tags etc <h2> tags etc but CSS styling is TOTALY ignored for position width z-index etc. and as follows here's the screen-shot JUST incase you require the css for where $content is being loaded #bodys { top:91px; position:absolute; width:100%; } #bodt { margin-left:auto; margin-right:auto; top:3px; position:relative; width:820px; height:42px; background-image:url('images/pagetop.png'); background-repeat:no-repeat; z-index: 0; } #bodm { margin-left:auto; margin-right:auto; top:3px; position:relative; width:820px; background-image:url('images/pagemid.png'); background-repeat:repeat-y; z-index: 0; } #bodb { margin-left:auto; margin-right:auto; bottom:-42px; position:relative; width:820px; height:42px; background-image:url('images/pagebot.png'); background-repeat:no-repeat; z-index:-1; } #menuo { position:absolute; bottom:-2px; z-index:199; } #contents { position:relative; top:5px; left:25px; width:770px; z-index:10; overflow: auto; color: #000000; line-height: 1.3em; font-size: 12px; } #content { position:absolute; top:5px; left:25px; width:760px; z-index:1; color: #000000; line-height: 1.3em; font-size: 12px; } #contents p{ margin-bottom: 0.7em; } #contents a{ font-weight:bold; color: #6fa5fd; border-bottom: 1px dotted #6fa5fd; }

    - by ganesh
    hi, I am trying to create a list view which as TextView that can display html content , an WebView and other basic TextViews.I tried to extend SimpleAdapter but i struck with the problem ,I will be glad if someone can point out the mistake i am doing.

  • [Android] Force close when trying to parse JSON with AsyncTask in the background

    - by robs
    Hello everyone, i'm new to android development and i'm playing around with json data. I managed to get the parsing to work. I want to show a ProgressDialog and i read that i need to use AsyncTask that. But for some reason i get a force close as soon as i put the same working code inside doInBackground() eventhough eclipse says everything is fine. Here is the source code: public class HomeActivity extends Activity { public class BackgroundAsyncTask extends AsyncTask<Void, Integer, Void> { ProgressDialog dialog = new ProgressDialog (HomeActivity.this); @Override protected void onPreExecute() { dialog.setMessage("Loading...please wait"); dialog.setIndeterminate(true); dialog.setCancelable(false); dialog.show(); } protected void onPostExecute() { dialog.dismiss(); } @Override protected Void doInBackground(Void... params) { try { URL json = new URL("http://www.corps-marchia.de/jsontest.php"); URLConnection tc = json.openConnection(); BufferedReader in = new BufferedReader(new InputStreamReader(tc.getInputStream())); String line; while ((line = in.readLine()) != null) { JSONArray ja = new JSONArray(line); JSONObject jo = (JSONObject) ja.get(0); TextView txtView = (TextView)findViewById(R.id.TextView01); txtView.setText(jo.getString("text")); } } catch (MalformedURLException e) { e.printStackTrace(); } catch (IOException e) { e.printStackTrace(); } catch (JSONException e) { e.printStackTrace(); } return null; } } @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); new BackgroundAsyncTask().execute(); } } Here is the error log: 01-08 12:33:48.225: ERROR/AndroidRuntime(815): FATAL EXCEPTION:

  • a program similar to ls with some modifications

    - by Bond
    Hi, here is a simple puzzle I wanted to discuss. A C program to take directory name as command line argument and print last 3 directories and 3 files in all subdirectories without using api 'system' inside it. suppose directory bond0 contains bond1, di2, bond3, bond4, bond5 and my_file1, my_file2, my_file3, my_file4, my_file5, my_file6 and bond1 contains bond6 my_file7 my_file8 my_file9 my_file10 program should output - bond3, bond4, bond5, my_file4, my_file5, my_file6, bond6, my_file8, my_file9, my_file10 My code for the above problem is here #include<dirent.h> #include<unistd.h> #include<string.h> #include<sys/stat.h> #include<stdlib.h> #include<stdio.h> char *directs[20], *files[20]; int i = 0; int j = 0; int count = 0; void printdir(char *); int count_dirs(char *); int count_files(char *); int main() { char startdir[20]; printf("Scanning user directories\n"); scanf("%s", startdir); printdir(startdir); } void printdir(char *dir) { printf("printdir called %d directory is %s\n", ++count, dir); DIR *dp = opendir(dir); int nDirs, nFiles, nD, nF; nDirs = 0; nFiles = 0; nD = 0; nF = 0; if (dp) { struct dirent *entry = 0; struct stat statBuf; nDirs = count_dirs(dir); nFiles = count_files(dir); printf("The no of subdirectories in %s is %d \n", dir, nDirs); printf("The no of files in %s is %d \n", dir, nFiles); while ((entry = readdir(dp)) != 0) { if (strcmp(entry->d_name, ".") == 0 || strcmp(entry->d_name, "..") == 0) { continue; } char *filepath = malloc(strlen(dir) + strlen(entry->d_name) + 2); if (filepath) { sprintf(filepath, "%s/%s", dir, entry->d_name); if (lstat(filepath, &statBuf) != 0) { } if (S_ISDIR(statBuf.st_mode)) { nD++; if ((nDirs - nD) < 3) { printf("The directory is %s\n",entry->d_name); } } else { nF++; if ((nFiles - nF) < 3) { printf("The files are %s\n", entry->d_name); } //if } //else free(filepath); } //if(filepath) } //while while ((entry = readdir(dp)) != 0) { if (strcmp(entry->d_name, ".") == 0 || strcmp(entry->d_name, "..") == 0) { continue; } printf("In second while loop *entry=%s\n",entry->d_name); char *filepath = malloc(strlen(dir) + strlen(entry->d_name) + 2); if (filepath) { sprintf(filepath, "%s/%s", dir, entry->d_name); if (lstat(filepath, &statBuf) != 0) { } if (S_ISDIR(statBuf.st_mode)) { printdir(entry->d_name); } } //else free(filepath); } //2nd while closedir(dp); } else { fprintf(stderr, "Error, cannot open directory %s\n", dir); } } //printdir int count_dirs(char *dir) { DIR *dp = opendir(dir); int nD; nD = 0; if (dp) { struct dirent *entry = 0; struct stat statBuf; while ((entry = readdir(dp)) != 0) { if (strcmp(entry->d_name, ".") == 0 || strcmp(entry->d_name, "..") == 0) { continue; } char *filepath = malloc(strlen(dir) + strlen(entry->d_name) + 2); if (filepath) { sprintf(filepath, "%s/%s", dir, entry->d_name); if (lstat(filepath, &statBuf) != 0) { fprintf(stderr, "File Not found? %s\n", filepath); } if (S_ISDIR(statBuf.st_mode)) { nD++; } else { continue; } free(filepath); } } closedir(dp); } else { fprintf(stderr, "Error, cannot open directory %s\n", dir); } return nD; } int count_files(char *dir) { DIR *dp = opendir(dir); int nF; nF = 0; if (dp) { struct dirent *entry = 0; struct stat statBuf; while ((entry = readdir(dp)) != 0) { if (strcmp(entry->d_name, ".") == 0 || strcmp(entry->d_name, "..") == 0) { continue; } char *filepath = malloc(strlen(dir) + strlen(entry->d_name) + 2); if (filepath) { sprintf(filepath, "%s/%s", dir, entry->d_name); if (lstat(filepath, &statBuf) != 0) { fprintf(stderr, "File Not found? %s\n", filepath); } if (S_ISDIR(statBuf.st_mode)) { continue; } else { nF++; } free(filepath); } } closedir(dp); } else { fprintf(stderr, "Error, cannot open file %s\n", dir); } return nF; } The above code I wrote is a bit not functioning correctly can some one help me to understand the error which is coming.So that I improve it further.There seems to be some small glitch which is not clear to me right now.

  • MVC 3 ModelView passing parameters between view & controller

    - by Tobias Vandenbempt
    I've been playing with MVC 3 in a test project and have the following issue. I have Group & Subscriber entities and those are coupled through a SubscriberGroup table. Using the DetailView of Group I open a view of SubscriberGroup containing all subscribers. This list has the option to filter. So far it all works, however when I call the AddToGroup method on the controller it fails. Specifically it goes into the method but doesn't pass the subscriberCheckedModels list.

  • ListView not showing up in fragment

    - by aindurti
    When I insert a listview in a fragment in my application, it doesn't show up after I populate it with items. In fact, the application crashes due to a NullPointerException. Can anybody help me? Here is the detail activity from which I show the fragments. package com.example.sample; import android.content.Intent; import android.os.Bundle; import android.support.v4.app.Fragment; import android.support.v4.app.FragmentTransaction; import android.support.v4.app.NavUtils; import android.widget.ArrayAdapter; import android.widget.ListView; import com.actionbarsherlock.app.ActionBar; import com.actionbarsherlock.app.ActionBar.Tab; import com.actionbarsherlock.app.SherlockFragmentActivity; import com.actionbarsherlock.view.MenuItem; /** * An activity representing a single Course detail screen. This activity is only * used on handset devices. On tablet-size devices, item details are presented * side-by-side with a list of items in a {@link CourseListActivity}. * <p> * This activity is mostly just a 'shell' activity containing nothing more than * a {@link CourseDetailFragment}. */ public class CourseDetailActivity extends SherlockFragmentActivity { @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_course_detail); // Show the Up button in the action bar. ActionBar actionBar = getSupportActionBar(); actionBar.setDisplayHomeAsUpEnabled(true); actionBar.setNavigationMode(ActionBar.NAVIGATION_MODE_TABS); // initiating both tabs and set text to it. ActionBar.Tab assignTab = actionBar.newTab().setText("Assignments"); ActionBar.Tab schedTab = actionBar.newTab().setText("Schedule"); ActionBar.Tab contactTab = actionBar.newTab().setText("Contact"); // Create three fragments to display content Fragment assignFragment = new Assignments(); Fragment schedFragment = new Schedule(); Fragment contactFragment = new Contact(); assignTab.setTabListener(new MyTabsListener(assignFragment)); schedTab.setTabListener(new MyTabsListener(schedFragment)); contactTab.setTabListener(new MyTabsListener(contactFragment)); actionBar.addTab(assignTab); actionBar.addTab(schedTab); actionBar.addTab(contactTab); ListView listView = (ListView) findViewById(R.id.assignlist); String[] values = new String[] { "Android", "iPhone", "WindowsMobile", "Blackberry", "WebOS", "Ubuntu", "Windows7", "Max OS X", "Linux", "OS/2" }; // First paramenter - Context // Second parameter - Layout for the row // Third parameter - ID of the TextView to which the data is written // Forth - the Array of data ArrayAdapter<String> adapter = new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, android.R.id.text1, values); // Assign adapter to ListView listView.setAdapter(adapter); } @Override public boolean onOptionsItemSelected(MenuItem item) { switch (item.getItemId()) { case android.R.id.home: // This ID represents the Home or Up button.

As you can see in the CourseDetailActvity, I populate smaple items in the listview to see if it the listview shows up. The fragment gets inflated properly, but when I try to add items to the listview, the application crashes!

  • Android Multiple objects in SimpleAdapter

    - by Adam Sherratt
    I have a need (unless you can think of a better way) of passing multiple objects to a custom list adapter. I know that I'm barking up the wrong tree here, and would appreciate someone setting me on the right course! Thanks playlistadapter = new MyPlaylistAdapter(MyApplication.getAppContext(), songsList, retained_songsList, folderMode, R.layout.file_view, new String[] { "songTitle","songAlbum", "songPath" }, new int[] { R.id.checkTextView, R.id.text2, R.id.text3 }); And my adapter class: public class MyPlaylistAdapter extends SimpleAdapter{ private ArrayList <Song> songsList = new ArrayList<Song>(); private ArrayList <Song> retained_songsList = new ArrayList<Song>(); private ArrayList<Song> playlistcheck = new ArrayList<Song>(); private String folderMode; private String TAG = "AndroidMediaCenter"; public MyPlaylistAdapter(Context context,List<Song> SongsList, List<Song> Retained_songsList, String FolderMode,int resource, String[] from, int[] to) { super(context, null, resource, from, to); songsList.clear(); songsList.addAll(SongsList); Log.i(TAG, "MyPlayListAdapter Songslist = " + songsList.size()); retained_songsList.clear(); retained_songsList.addAll(Retained_songsList); folderMode = FolderMode;

checkTextView.setText(tracks); if(folderMode.equals("Playlists")){ checkTextView.setBackgroundColor(Color.GREEN); checkTextView.setChecked(false); try { int listsize_rs = retained_songsList.size(); for (int j = 0;

  • Hiding Options of a Select with JQuery

    - by Syed Abdul Rahman
    Okay, let's start with an example. Keep in mind, this is only an example. <select id = "selection1">     <option value = "1" id = "1">Number 1</option>     <option value = "2" id = "2">Number 2</option>     <option value = "3" id = "3">Number 3</option> </select> Now from here, we have a dropdown with 3 options. What I want to do now is to hide an option. Adding style = "display:none" will not help. The option would not appear in the dropdownlist, but using the arrow keys, you can still select it. Essentially, it does exactly what the code says. It isn't displayed, and it stops there. A JQuery function of $("#1").hide() will not work. Plus, I don't only want to hide the option, I want to completely remove it. Any possibility on doing so? Do I have to use parent/sibling/child elements? If so, I'm still not sure how. Any help on this would be greatly appreciated. Thanks.           Another question - It's related Ok, so I found out that there is a .remove() available in JQuery. Works well. But what if I want to bring it back? if(condition)     {     $(this).remove();     } I can loops this. Shouldn't be complicated. But the thing of which I am trying to do is this: Maximum Capacity of Class: (Input field here) Select Room: (Dropdown here) What I'd like for it to do is to update is Dropdown using a function such as .change() or .keyup. I could create the dropdown only after something is typed. At a change or a keyup, execute the dropdown accordingly. But what I am doing is this: $roomarray = mysql_query("SELECT *     FROM         (         SELECT *,         CASE         WHEN type = 'Classroom' THEN 1         WHEN type = 'Computer laboratory' THEN 2         WHEN type = 'Lecture Hall' THEN 3         WHEN type = 'Auditorium' THEN 4         END AS ClassTypeValue         FROM rooms         ) t     ORDER BY ClassTypeValue, maxppl, roomID"); echo "<select id = \"room\">"; while ($rooms = mysql_fetch_array($roomarray)) { ?> <option value=<?php echo $rooms['roomID']; ?> id=<?php echo $rooms['roomID']; ?>><?php echo $rooms['type']; echo "&nbsp;"; echo $rooms['roomID']; echo "&nbsp;("; echo $rooms['maxppl']; echo ")"; ?></option> <?php } echo "</select>"; Yes, I know it is very messy. I plan to change it later on. But the issue now is this: Can I toggle the removal of the options according to what has been typed? Is it possible to do so with a dropdown made from a loop? Because I sure as hell can't keep executing SQL Queries. Or is that even an option? Because if it's possible, I still think it's a bad one.

  • Lua metatable Objects cannot be purge from memory?

    - by Prometheus3k
    Hi there, I'm using a proprietary platform that reported memory usage in realtime on screen. I decided to use a Class.lua I found on http://lua-users.org/wiki/SimpleLuaClasses However, I noticed memory issues when purging object created by this using a simple Account class. Specifically, I would start with say 146k of memory used, create 1000 objects of a class that just holds an integer instance variable and store each object into a table. The memory used is now 300k I would then exit, iterating through the table and setting each element in the table to nil. But would never get back the 146k, usually after this I am left using 210k or something similar. If I run the load sequence again during the same session, it does not exceed 300k so it is not a memory leak. I have tried creating 1000 integers in a table and setting these to nil, which does give me back 146k. In addition I've tried a simpler class file (Account2.lua) that doesn't rely on a class.lua. This still incurs memory fragmentation but not as much as the one that uses Class.lua Can anybody explain what is going on here? How can I purge these objects and get back the memory? here is the code --------Class.lua------ -- class.lua -- Compatible with Lua 5.1 (not 5.0). --http://lua-users.org/wiki/SimpleLuaClasses function class(base,ctor) local c = {} -- a new class instance if not ctor and type(base) == 'function' then ctor = base base = nil elseif type(base) == 'table' then -- our new class is a shallow copy of the base class! for i,v in pairs(base) do c[i] = v end c._base = base end -- the class will be the metatable for all its objects, -- and they will look up their methods in it. c.__index = c -- expose a ctor which can be called by () local mt = {} mt.__call = function(class_tbl,...) local obj = {} setmetatable(obj,c) if ctor then ctor(obj,...) else -- make sure that any stuff from the base class is initialized! if base and base.init then base.init(obj,...) end end return obj end c.init = ctor c.instanceOf = function(self,klass) local m = getmetatable(self) while m do if m == klass then return true end m = m._base end return false end setmetatable(c,mt) return c end --------Account.lua------ --Import Class template require 'class' local classname = "Account" --Declare class Constructor Account = class(function(acc,balance) --Instance variables declared here. if(balance ~= nil)then acc.balance = balance else --default value acc.balance = 2097 end acc.classname = classname end) --------Account2.lua------ local account2 = {} account2.classname = "unnamed" account2.balance = 2097 -----------Constructor 1 do local metatable = { __index = account2; } function Account2() return setmetatable({}, metatable); end end --------Main.lua------ require 'Account' require 'Account2' MAX_OBJ = 5000; test_value = 1000; Obj_Table = {}; MODE_ACC0 = 0 --integers MODE_ACC1 = 1 --Account MODE_ACC2 = 2 --Account2 TEST_MODE = MODE_ACC0; Lua_mem = ""; print("##1) collectgarbage('count'): " .. collectgarbage('count')); function Load() for i=1, MAX_OBJ do if(TEST_MODE == MODE_ACC0 )then table.insert(Obj_Table, test_value); elseif(TEST_MODE == MODE_ACC1 )then table.insert(Obj_Table, Account(test_value)); --Account.lua elseif(TEST_MODE == MODE_ACC2 )then table.insert(Obj_Table, Account2()); --Account2.lua Obj_Table[i].balance = test_value; end end print("##2) collectgarbage('count'): " .. collectgarbage('count')); end function Purge() --metatable purge if(TEST_MODE ~= MODE_ACC0)then --purge stage 0: print("set each elements metatable to nil") for i=1, MAX_OBJ do setmetatable(Obj_Table[i], nil); end end --purge stage 1: print("set table element to nil") for i=1, MAX_OBJ do Obj_Table[i] = nil; end --purge stage 2: print("start table.remove..."); for i=1, MAX_OBJ do table.remove(Obj_Table, i); end print("...end table.remove"); --purge stage 3: print("create new object_table {}"); Obj_Table= {}; --purge stage 4: print("collectgarbage('collect')"); collectgarbage('collect'); print("##3) collectgarbage('count'): " .. collectgarbage('count')); end --Loop callback function OnUpdate() collectgarbage('collect'); Lua_mem = collectgarbage('count'); end ------------------- --NOTE: --On start of game runs Load(), another runs Purge() --Update I've updated the code with suggestions from comments below, and will post my findings later today.

  • What is the RFC complicant and working regular expression to check if a string is a valid URL

    - by bestis
    There is question by the almost the same name already: What is the best regular expression to check if a string is a valid URL I don't understand this stackoverflow. It seems like I need reputation to comment an answer. As I don't have it, I don't know how to tell/ask that the proposed solution doesn't seem to work. So I'm forced to make a new question and ask for the solution this way? But that regexp seems to fail in input which has IPv6 address in it: For example facebook's IPv6 address: http://2620:0:1cfe:face:b00c::3/ Also link to localhost fails: http://::1/ Or is PHP to blame?

  • how to use a class method as a WIN32 application callback method (WINPROC)... Error static struct HI

    - by numerical25
    I am receiving errors and at the same time trying to make this work so please read what I got to say. Thanks.... I am creating a c++ application and majority of the application is encapsulated into a class. That means that my WinProc function is a static class method that I use as my call back method for my win32 application. The problem is that since I created that as a win32 application, every class member I use inside that method has to be static as well. Including my HINSTANCE class which I use inside of it. Now I receive this error error LNK2001: unresolved external symbol "public: static struct HINSTANCE__ I need to figure out how to make this all work and below is my class declaration. My static member static HINSTANCE m_hInst is causing the error I believe. #pragma once #include "stdafx.h" #include "resource.h" #define MAX_LOADSTRING 100 class RenderEngine { protected: int m_width; int m_height; ATOM RegisterEngineClass(); public: static HINSTANCE m_hInst; //<------ This is causing the error HWND m_hWnd; int m_nCmdShow; TCHAR m_szTitle[MAX_LOADSTRING]; // The title bar text TCHAR m_szWindowClass[MAX_LOADSTRING]; // the main window class name bool InitWindow(); bool InitDirectX(); bool InitInstance(); //static functions static LRESULT CALLBACK WndProc(HWND hWnd, UINT message, WPARAM wParam, LPARAM lParam); static INT_PTR CALLBACK About(HWND hDlg, UINT message, WPARAM wParam, LPARAM lParam); int Run(); }; Below is the implementation #include "stdafx.h" #include "RenderEngine.h" bool RenderEngine::InitWindow() { RenderEngine::m_hInst = NULL; // Initialize global strings LoadString(m_hInst, IDS_APP_TITLE, m_szTitle, MAX_LOADSTRING); LoadString(m_hInst, IDC_RENDERENGINE, m_szWindowClass, MAX_LOADSTRING); if(!RegisterEngineClass()) { return false; } if(!InitInstance()) { return false; } return true; } ATOM RenderEngine::RegisterEngineClass() { WNDCLASSEX wcex; wcex.cbSize = sizeof(WNDCLASSEX); wcex.style = CS_HREDRAW | CS_VREDRAW; wcex.lpfnWndProc = RenderEngine::WndProc; wcex.cbClsExtra = 0; wcex.cbWndExtra = 0; wcex.hInstance = m_hInst; wcex.hIcon = LoadIcon(m_hInst, MAKEINTRESOURCE(IDI_RENDERENGINE)); wcex.hCursor = LoadCursor(NULL, IDC_ARROW); wcex.hbrBackground = (HBRUSH)(COLOR_WINDOW+1); wcex.lpszMenuName = MAKEINTRESOURCE(IDC_RENDERENGINE); wcex.lpszClassName = m_szWindowClass; wcex.hIconSm = LoadIcon(wcex.hInstance, MAKEINTRESOURCE(IDI_SMALL)); return RegisterClassEx(&wcex); } LRESULT CALLBACK RenderEngine::WndProc(HWND hWnd, UINT message, WPARAM wParam, LPARAM lParam) { int wmId, wmEvent; PAINTSTRUCT ps; HDC hdc; switch (message) { case WM_COMMAND: wmId = LOWORD(wParam); wmEvent = HIWORD(wParam); // Parse the menu selections: switch (wmId) { case IDM_ABOUT: DialogBox(m_hInst, MAKEINTRESOURCE(IDD_ABOUTBOX), hWnd, About); break; case IDM_EXIT: DestroyWindow(hWnd); break; default: return DefWindowProc(hWnd, message, wParam, lParam); } break; case WM_PAINT: hdc = BeginPaint(hWnd, &ps); // TODO: Add any drawing code here...
