  • Converting text to bits (1's and 0's)

    - by Morano88
    I'm implementing an MD-5 Hashing algorithm and I want to convert the text I have to bits so I can start manipulating them. As you know Hashing require taking block of bits and then manipulating them. There are many ways to do that but I can't determine the best/easiest way to just convert the text (string) into array of bits. Any clue ? In C#

  • iPhone memory management, a newbie question

    - by Reuven
    Hi, I've seen in (Apple) sample code two types of ways of allocation memory, and am not sure I understand the difference and resulting behavior. // FAILS NSMutableArray *anArray = [NSMutableArray array]; [anArray release]; // WORKS NSMutableArray *anArray1 = [[NSMutableArray alloc] init]; [anArray release]; By "FAILS" I mean I get crashes/runtime warnings etc., and not always as soon as I call the release... Any explanation appreciated. Thanks

  • Flex Drag & Drop: Detecting when all data has been moved from source to destination

    - by Adam Tuttle
    I have two mx:TileList controls that I'm using to allow editing of objects in batch. The first contains a collection of all available data, and the 2nd contains the current batch. Both are bound to ArrayCollections, and using the native drag-n-drop functionality of the TileList control the data is moved from one ArrayCollection to the other when an object is dragged between them. I need to change the currentState to show & reset the batch manipulation controls when the batch count goes from 0 to n or n to 0 items. Based on the documentation, I would have thought that I should listen to the dragComplete event, but my testing shows that instead of firing after the data has been removed from the source ArrayCollection and added to the destination ArrayCollection, it fires (consistently) between these two actions. Both lists are similar to this: <mx:TileList id="srcList" dragEnabled="true" dropEnabled="true" dragMoveEnabled="true" dataProvider="{images}" dragComplete="handleDragComplete(event)" allowMultipleSelection="true" /> And here's the source of the handleDragComplete function: private function handleDragComplete(e:DragEvent):void{ trace(e.dragInitiator.name + '.dragComplete: batch.length=' + batch.length.toString()); trace(e.dragInitiator.name + '.dragComplete: images.length=' + images.length.toString()); if (batch.length > 0){ currentState = 'show'; }else{ currentState = ''; } } And lastly, here's some example output from running the code. These are all run one after the other. Case 1: The application loads with 10 objects in the first list and the batch is empty. I dragged 1 object from the source list to the batch list. srcList.dragComplete: batch.length=1 srcList.dragComplete: images.length=10 (Expected: 1,9) Clearly, the object has been added to the batch ArrayCollection but not removed from the source. Case 2: Now, I'll drag a 2nd object into the batch. srcList.dragComplete: batch.length=2 srcList.dragComplete: images.length=9 (Expected: 2,8) Firstly, we can see that images.length has changed, showing that the object that I dragged from the source list to the batch list was removed AFTER the dragComplete event fired. The same thing happens this time: The new object is added to the batch ArrayCollection (batch.length=2), the dragComplete event fires (running these traces), and then the object is removed from the source ArrayCollection. Case 3: Now, I'll drag both images from the batch list back to their original location in the source list. batchList.dragComplete: batch.length=2 batchList.dragComplete: images.length=10 (Expected: 0,10) We can see that batch.length hasn't gone down, but the source images array is back at its original length of 10. QUESTION: Am I doing something wrong? Is there another event I could listen for? (Note: I tried both DragExit and DragDrop, just to be sure, and those behave as expected, but are not what I need.) Or is there another way to get the data that I want? Or... have I found a bug in the SDK?

  • iPhone SDK: Track users location using GPS

    - by Nic Hubbard
    I have a few questions about CoreLocation and GPS. First, what method in core location is used to continually get the users current coordinates? And at what interval should these be retrieved? Second, should these coordinates be pushed into a NSMutableArray each time they are received, so that the array of coordinates will represent the users path? Thanks, just wanting to get started getting me mind around this.

    - by WilliamKF
    I have an unsigned char array that I need in a std::string, but my current way uses reinterpret_cast which I would like to avoid. Is there a cleaner way to do this? unsigned char my_txt[] = { 0x52, 0x5f, 0x73, 0x68, 0x7e, 0x29, 0x33, 0x74, 0x74, 0x73, 0x72, 0x55 } unsigned int my_txt_len = 12; std::string my_std_string(reinterpret_cast<const char *>(my_txt), my_txt_len);

  • How to checking wether an object has a specific method or not

    - by Ghommey
    Hey, I want to use a method of an object. Like $myObject->helloWorld(). However there are a couple of methods so I loop through an array of method names and call the method like this: my $methodName ="helloWorld"; $myObject->$methodNames; This works quite nice but some objects don't have all methods. How can I tell wether $myObject has a method called helloWorld or not?

  • Is it bad to use a model directly from a view in codeigniter?

    - by jason
    I know normally the data is passed thru to the view with the controller. however, currently in my view I load my model ($this-load-model('Db_model');) so i can use it in a loop to retrieve a users profile picture path from a array of IDs that is passed from controller. Will loading the db model in the view to accomplish this make my site more vulnerable or bad form? To me it seems to be outside of MVC concept but its working atm. thanks

  • how to scan a LAN for live hosts using PHP and SNMP?

    - by aag
    I would like to have a quick script listing all active hosts in a LAN, and I am a bit lost. From other posts I figured that this can be done most effectively by polling the DHCP server (in my case a Lancom router) using SNMP. However, I am not familiar with the SNMP commands in PHP. Is snmpwalk() the correct function? Can I get snmpwalk() or any other php function to return an array that contains a list of all live hosts?

  • Magento and configurable product attributes

    - by artega
    I have an issue with displaying product custom attributes. I've read every resources through google but still no success. The problem is that I have to show size attribute of configurable product on category grid and list view. Every solution on google suggested something like $_product->getAttributeText('size') but I ended up at just a single string - "S" or "M" instead of an array. How can I fetch all possible sizes of all simple products which belongs to particular configurable product without much hassle?

  • Twitter RSS feed, [domdocument.load]: failed to open stream:

    - by dave1019
    hi i'm using the following: <?php $doc = new DOMDocument(); $doc->load('http://twitter.com/statuses/user_timeline/XXXXXX.rss'); $arrFeeds = array(); foreach ($doc->getElementsByTagName('item') as $node) { $itemRSS = array ( 'title' => $node->getElementsByTagName('title')->item(0)->nodeValue, 'desc' => $node->getElementsByTagName('description')->item(0)->nodeValue, 'link' => $node->getElementsByTagName('link')->item(0)->nodeValue, 'date' => $node->getElementsByTagName('pubDate')->item(0)->nodeValue ); array_push($arrFeeds, $itemRSS); } for($i=0;$i<=3;$i++) { $tweet=substr($arrFeeds[$i]['title'],17); $tweetDate=strtotime($arrFeeds[$i]['date']); $newDate=date('G:ia l F Y ',$tweetDate); if($i==0) { $b='style="border:none;"'; } $tweetsBox.='<div class="tweetbox" ' . $b .

HTTP/1.1 502 Bad Gateway I've read that the above code is dependant on Twitter beign available and I know it gets rather busy sometimes. Is there either a better way of receiving twits, or is there any kind of error trapping i could do to just to display "tweets are currently unavailable..." ind of message rather than causing an error. I'm usnig ModX CMS so any parse error kills the site rather than just ouputs a warning. thanks.

  • accessing id property via javascript

    - by webzide
    Dear experts Is there a way to access the ID of an dom element? I don't mean using the getElementById attribute to find out a array of objects. Bascially I already know the DOM element and that object reference is at hand. All I need is to access the ID property. I know something like if(element.id==value) won't work. Thanks in advance.
