  1. Hello all/gamedev,   I'm having some trouble rendering the yAxis after adding a new data series. I have a function that will allow me to add a data series dynamically to my highchart and for my use case I'll be entering only integer value series names. The categories are sorted in ascending order. $('#addSeries').on('click', function() {         //first check if value is already a series         var seriesid = document.getElementById('txtValue').value;         getSeriesIDIndex(seriesid, function(idindex) {             //if it doesnt exist, add it to chart             if (idindex == -1) {                 categories.push(parseInt(seriesid));                 categories = categories.sort(sortNumber);                 chart.yAxis[0].setCategories(categories, false);                 getCategoryIndex(parseInt(seriesid), function(cindex) {                     chart.addSeries({name: seriesid,  data: [{x: currentDate.getTime(), y: cindex}]}, false);                                          for (i = 0; i < chart.series.length; i++) {                         (function(i) {                             getCategoryIndex(chart.series[i].name, function(cindex) {                                 for (y = 0; y < chart.series[i].data.length; y++) {                                     chart.series[i].data[y].y = cindex;                                     chart.redraw();                                 }                             });                         })(i);                     }                                          chart.redraw();                 });             }         });     }); Only when you add a series that has the highest integer value does the chart display properly again.   To illustrate I've created a jsfiddle (link: First add a series "10", then add "5". You will see it displayed incorrectly at this point. Then add a series "15" and it will correct itself.   Any thoughts/ideas would be greatly appreciated!
  2. I sent them an email in regards to my question and also just asked for permission to use the api instead of doing all the extra web dev. waiting to hear back now... usually takes them a week to respond.
  3. I would like to write an app that you can scan a barcode and link to's website. The barcode scans in as UPC code and the only way I can link to Amazon is with ASIN. The <b>Associates API</b> has the ability to convert UPC to ASIN but in the Product Advertising API License Agreement:   What if I wrote a website using the Associates API to convert UPC to ASIN and then use my mobile phone to interface with said website to get ASIN from UPC. Would that be any trouble? I don't see why Amazon wouldn't want people to be able to link to their website off of UPC...   Not sure if this is the right place to ask this question. Thanks
  4. ahh I can't believe I didn't think of that. for some reason I thought unsigned char was an invalid type and just didn't even bother trying... it's been a while since I jumped into a C project though. thanks again!
  5.   I tried changing it to %.2x but it still displays the same. Also that wouldn't help me later in my code I don't think when I'm doing assignments like gif->Packed = buffer[10];   Btw my typdef for BYTE is char, not sure if that matters... I do that since char is a byte long and all I need is a byte for each variable in my gif struct.
  6. hey gamedev, I'm trying to read a file 1 byte at a time basically and I'm getting some strange results.   Here is my code int main(int argc, char** argv) {     GifInfo gif;     FILE* gifFile;     long lSize;     BYTE* buffer = 0;     size_t result;     gifFile = fopen("mario.gif", "rb");     if (gifFile == 0) {         printf("Failed to open gif\n");         return 0;     }     //obtain file size     fseek(gifFile, 0, SEEK_END);     lSize = ftell(gifFile);     rewind(gifFile);     //allocate memory to contain the whole file     buffer = (BYTE*) malloc(lSize);     if (buffer == 0) {         printf("Failed to allocate memory\n");         return 0;     }     memset(buffer, 0, lSize);     //copy file to buffer     result = fread(buffer, 1, lSize, gifFile);     if (result != lSize) {         printf("Could not copy file to allocated buffer\n");         return 0;     }     int i = 0;     for (i = 0; i < 20; i++)         printf("Buffer %d: %#x\n", i, buffer[i]);     //do stuff     readGif(buffer, &gif);     if (verifyGif(&gif)) {         printf("Valid GIF!\n");         printGifInfo(&gif);         }     else         printf("Invalid GIF!\n");          //cleanup     fclose(gifFile);     free(buffer);     return 0; }   Here is my output //... Buffer 0: 0x47 Buffer 1: 0x49 Buffer 2: 0x46 Buffer 3: 0x38 Buffer 4: 0x39 Buffer 5: 0x61 Buffer 6: 0x40 Buffer 7: 0x1 Buffer 8: 0x20 Buffer 9: 0x1 Buffer 10: 0xfffffff7 Buffer 11: 0xffffffdc Buffer 12: 0 Buffer 13: 0x4 Buffer 14: 0x4 Buffer 15: 0x4 Buffer 16: 0x4 Buffer 17: 0xffffffac Buffer 18: 0x4 Buffer 19: 0xffffffdc Valid GIF! //...   The problem comes in at buffer 10, 11, 17, 19. I've tryed initializing buffer and filling it with 0s as well but it still gets read like that and it's causing issues with the rest of my code. I'm sure I'm looking over something very simple. I appreciate the help.

  9. edit: i'm editing my post to better explain my problem.   I have an android application using swipe tabs to navigate between fragments. I have 2 fragments defined in xml file and 1 main activity. Whenever I run my application I'm getting the tabs to show up properly with the correct names "Administration", "Scan", "About"... but the page is blank. When I step through my debugger to check the return value of onCreateView (in my FragmentPagerAdapter code below) it appears to be returning correct value... I can't figure out why I keep getting a blank screen.   Here is my activity_main.xml < xmlns:android="" xmlns:tools="" android:id="@+id/pager" android:layout_width="match_parent" android:layout_height="match_parent" tools:context="com.atd.giftmonster.MainActivity" /> Here is my public class MainActivity extends ActionBarActivity implements ActionBar.TabListener { ViewPager mViewPager; DFragmentManager mFragmentManager; private static EditText textEmail; private static EditText textPw; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); List<String> titles = new ArrayList<String>(); titles.add("administrator"); titles.add("scan"); titles.add("about"); List<Integer> layoutids = new ArrayList<Integer>(); layoutids.add(R.layout.fragment_admin); layoutids.add(R.layout.fragment_scan); layoutids.add(R.layout.fragment_scan); // Set up the action bar. final ActionBar actionBar = getSupportActionBar(); actionBar.setNavigationMode(ActionBar.NAVIGATION_MODE_TABS); mFragmentManager = new DFragmentManager(getSupportFragmentManager(), layoutids, titles); // Set up the ViewPager with the sections adapter. mViewPager = (ViewPager) findViewById(; mViewPager.setAdapter(mFragmentManager); // When swiping between different sections, select the corresponding // tab. We can also use ActionBar.Tab#select() to do this if we have // a reference to the Tab. mViewPager.setOnPageChangeListener(new ViewPager.SimpleOnPageChangeListener() { @Override public void onPageSelected(int position) { actionBar.setSelectedNavigationItem(position); } }); // For each of the sections in the app, add a tab to the action bar. for (int i = 0; i < mFragmentManager.getCount(); i++) { actionBar.addTab( actionBar.newTab() .setText(mFragmentManager.getPageTitle(i)) .setTabListener(this)); } } Here is my FragmentPagerAdapter w/ static fragment class public class DFragmentManager extends FragmentPagerAdapter { List<String> mTitle; List<Integer> mLayoutID; List<Fragment> mFragments; FragmentManager mFragmentManager; public DFragmentManager(FragmentManager fm, List<Integer> layoutIDs, List<String> layoutTitles) { super(fm); mFragments = new ArrayList<Fragment>(); mLayoutID = layoutIDs; mFragmentManager = fm; mTitle = layoutTitles; int size = mLayoutID.size(); for (int i = 0; i < size; i++) { mFragments.add(DFragment.newInstance(mLayoutID.get(i))); } } @Override public Fragment getItem(int position) { return mFragments.get(position); } @Override public int getCount() { return mFragments.size(); } @Override public CharSequence getPageTitle(int position) { //return (CharSequence)new String("ss"); //return (CharSequence) mFragments.get(position).getTitle(); return (CharSequence) mTitle.get(position); } public Fragment getFragment(int position) { return mFragments.get(position); } public static class DFragment extends Fragment { private View mView; private static final String ARG_LAYOUT_ID = "layout_id"; public static final DFragment newInstance(int layoutID) { DFragment fragment = new DFragment(); Bundle bundle = new Bundle(); bundle.putInt(ARG_LAYOUT_ID, layoutID); fragment.setArguments(bundle); return fragment; } @Override public View onCreateView(LayoutInflater inflater, ViewGroup group, Bundle bundle) { int resourceID = getArguments().getInt(ARG_LAYOUT_ID); mView = inflater.inflate(resourceID, group, false); return mView; } public View getView() { return mView; } }
  10. Hello GameDev   I'm having some issues building my dev environment for GTK+ in OSX 10.8. I have followed the instructions from but when I get to the part where it says to run command:   jhbuild bootstrap   I get the following error everytime.

    php session manager help

    that did the trick. I also had $session->start_session being called multiple times on a single page because I was including 'header.php' on everything. thank you for the help.

    php session manager help

    thank you for replying. i tried commenting out session_regenerate_id() before and it didn't have any effect. I just tried it again and my session still regenerates on every page load.   i thought for a while I wasn't loading sessions on the appropriate pages correctly $session = new session();   if (!session_id()) { if ($_SERVER["HTTPS"] != "on") $session->start_session('_s', true); else $session->start_session('_s', false); }   but no matter how I seem to change this everything is still not working. uid, username, and login_string are still not being accessed on the next page load. So how do I refer to the old session_id() so I can update it in db?   thanks again!
  13. Hello gamedev   I'm currently trying to implement a secure login script using https, mysql and sesssions. I've been following this guide from here to manage sessions:   My problem is that my session data is not being stored from my login script (in logindb.php). The session_id is changing on every single page load and encrypts the data coming in/out to db and I'm not sure if this is whats causing the data to not carry over to next page load.   I've been debugging for a while now and cannot seem to come to a solution. I think maybe I just don't understand how sessions work. Sorry for the long post, I've included my code below for anyone who wants to help me look over it for any issues.   Much appreciated   ./inc/logindb.php   <?php   require_once('session.class.php'); $session = new session(); $session->start_session('_s', true);   function login($email, $password, $mysqli) { // Using prepared Statements means that SQL injection is not possible.     if ($stmt = $mysqli->prepare("SELECT uid, username, password, salt FROM login_ids WHERE email = ?

  14. Hello everybody, I'm sure this topic has been covered quite extensively and let me start out by saying I understand what Big-O notation is. The problem I have is that I dont really know how to analyze and show why I think the Big-O notation is what it is. By looking at it I don't have any nested loops, and it just loops through N times depending on the size of the input. I assume its O(n) but I need to be sure. The code is kind of lengthy so that's why I'm not posting it, I'm basically just looking for some direction. If your boss asked you what the time complexity is for your function, how would you tell him? Thanks

    Alpha Transparency DX11

    So I figured out the blue is just too opaque to see through, if I change the color to something lighter it is all partially transparent. EDIT: Alright, so apparently irfanview when saving png images makes you select a color to make transparent. It makes that color plus everything else slightly transparent. I opened the images and edited them in photoshop and everything is looking good now.
