  • Allow users to pull temporary data then delete table?

    - by JM4
    I don't know the best way to title this question but am trying to accomplish the following goal: When a client logs into their profile, they are presented with a link to download data from an existing database in CSV format. The process works, however, I would like for this data to be 'fresh' each time they click the link so my plan was - once a user has clicked the link and downloaded the CSV file, the database table would 'erase' all of its data and start fresh (be empty) until the next set of data populated it. My EXISTING CSV creation code: <?php $host = 'localhost'; $user = 'username'; $pass = 'password'; $db = 'database'; $table = 'tablename'; $file = 'export'; $link = mysql_connect($host, $user, $pass) or die("Can not connect." . mysql_error()); mysql_select_db($db) or die("Can not connect."); $result = mysql_query("SHOW COLUMNS FROM ".$table.""); $i = 0; if (mysql_num_rows($result) > 0) { while ($row = mysql_fetch_assoc($result)) { $csv_output .= $row['Field'].", "; $i++; } } $csv_output .= "\n"; $values = mysql_query("SELECT * FROM ".$table.""); while ($rowr = mysql_fetch_row($values)) { for ($j=0;$j<$i;$j++) { $csv_output .= '"'.$rowr[$j].'",'; } $csv_output .= "\n"; } $filename = $file."_".date("Y-m-d",time()); header("Content-type: application/vnd.ms-excel"); header("Content-disposition: csv" . date("Y-m-d") . ".csv"); header( "Content-disposition: filename=".$filename.".csv"); print $csv_output; exit; ?> any ideas?

  • Doing a global count of an object type (like Users), best practice?

    - by user246114
    Hi, I know keeping global counters is frowned upon in app engine. I am interested in getting some stats though, like once every 24 hours. For example, I'd like to count the number of User objects in the system once every 24 hours. So how do we do this? Do we simply keep a set of admin tool functions which do something like: SELECT FROM com.me.project.server.User; and just see what the size of the returned List is? This is kind of a bummer because the datastore would have to deserialize every single User instance to create the returned list, right? I could optimize this possibly by asking for only the keys to be returned, so the whole User object doesn't have to be deserialized. Then again, a global counter for # of users probably would create too much contention, because there probably won't be hundreds of signups a minute for the service I'm creating. How should we go about doing this? Getting my total number of users once a day is probably a pretty typical operation? Thank you

  • Bizarre static_cast trick?

    - by Rob
    While perusing the Qt source code I came across this gem: template <class T> inline T qgraphicsitem_cast(const QGraphicsItem *item) { return int(static_cast<T>(0)->Type) == int(QGraphicsItem::Type) || (item && int(static_cast<T>(0)->Type) == item->type()) ? static_cast<T>(item) : 0; } Notice the static_cast<T>(0)->Type? I've been using C++ for many years but have never seen 0 being used in a static_cast before. What is this code doing and is it safe? Background: If you derive from QGraphicsItem you are meant to declare an unique enum value called Type that and implement a virtual function called type that returns it, e.g.: class Item : public QGraphicsItem { public: enum { Type = MAGIC_NUMBER }; int type() const { return Type; } ... }; You can then do this: QGraphicsItem* item = new Item; ... Item* derivedItem = qgraphicsitem_cast<Item*>(item); This will probably help explain what that static_cast is trying to do.

  • How to make an mutable C array for this data type?

    - by mystify
    There's this instance variable in my objective-c class: ALuint source; I need to have an mutable array of OpenAL Sources, so in this case probably I need a mutable C-array. But how would I create one? There are many questions regarding that: 1) How to create an mutable C-array? 2) How to add something to that mutable C-array? 3) How to remove something from that mutable C-array? 4) What memory management pitfalls must I be aware of? Must i free() it in my -dealloc method? And yes, I think this is something for the nice community wiki...

  • Can I use anything other than BIGINT as Primary Key data type in SQLite?

    - by weenet
    I was psyched about the possibility of using SQLite as a database solution during development so that I could focus on writing the code first and dynamically generating the db at runtime using NHibernate's ShemaExport functionality. However, I'm running into a few issues, not the least of which is that it seems that SQLite requires me to use Int64 for my primary keys (vs, say, Int32 or Guid). Is there any way around this?

    - by Armentage
    I want to build a simple application that looks up words against Wiktionary to see if they exist. Is there a standard API supported by the Wiktionary software that would let me do this? Alternatively, is there any way I can pull down the dictionary data that backs a Wiktionary? There are many international variants who's data I would love to put a different front-end around.

  • Encoding GBK2312 Condundrum

    - by user792271
    I am an amateur coder and I have a small problem. My goal is to have one text input with two buttons. The first button uses a bit of Javascript called SundayMorning to translate the text (to Chinese) The second button submits the text to a URL. The URl requires that Chinese text be encoded it in GBK2312 character set. I have duct taped together various found code to the result I have now. Due to the finicky behavior of the SundayMorning Javascript, my solution is to have two input boxes, the second of which I will hide. Right now, this doesn't work: I am unable to encode the Chinese in GBK2312, no matter what I try. BONUS CONUNDRUM: The second box copies my input letter by letter as I type, but does not copy the Chinese translation that the Javascript returns. Sorry for my janky amateur code. I defer to those more clever, if you have any kind suggestions. <head> <meta http-equiv="Content-Type" content="text/html; charset=GB2312" /> <script type='text/javascript' Src='https://ajax.googleapis.com/ajax/libs/jquery/1.6.1/jquery.min.js'> </script> ///THIS JS TRANSLATES THE TEXT INLINE <script type="text/javascript" src="jquery.sundaymorning.js"> </script> <script type="text/javascript"> $(function() { $('#example3').sundayMorningReset(); $('#example3 input[type=image]').click(function(evt) { $.sundayMorning( $('#example3 input[type=text]').val(),{source:'en', destination:'ZH', menuLeft:evt.pageX, menuTop:evt.pageY},function(response) {$('#example3 input[type=text]').val(response.translation);});});}); </script> /// ///THIS PUTS THE CONTENT OF THE TRANSLATION BOX INTO THE SUBMISSION BOX <script type="text/javascript"> $(document).ready(function(){ var $url = $("#url"); $("#track").keyup(function() { $url.val(this.value);}); $("#track").blur(function() { $url.val(this.value);});}); </script> ///THIS PUTS THE CONTENT OF THE SUBMISSION INSIDE A URL <SCRIPT type="text/javascript"> function goToPage(url) { var initial = "http://example.com/"; var extension = ".html"; document.something.action=initial+url+extension; } </SCRIPT> </head> <body> <div id="featured"> <div id="example3"> <input type="text" name="track" id="track" value="" class="box"onkeydown="javascript:if (event.which || event.keyCode){if ((event.which == 13) || (event.keyCode == 13)) {document.getElementById('mama').click();}};"/> <input type="image" src="http://taobaofieldguide.com/images/orange-translate-button.png" id="searchsubmit" value="Translate" class="btn" /> </div> <FORM name="something" method="post" onsubmit="goToPage(this.url.value);"> <input type="text" id="url";> <INPUT type="submit" id="mama" value="GO" > </FORM> </div> </body>

  • Buffer size: N*sizeof(type) or sizeof(var)? C++

    - by flyout
    I am just starting with cpp and I've been following different examples to learn from them, and I see that buffer size is set in different ways, for example: char buffer[255]; StringCchPrintf(buffer, sizeof(buffer), TEXT("%s"), X); VS char buffer[255]; StringCchPrintf(buffer, 255*sizeof(char), TEXT("%s"), X); Which one is the correct way to use it? I've seen this in other functions like InternetReadFile, ZeroMemory and MultiByteToWideChar.

  • Do I have to put parent::__construct($config) in my CakePHP data source?

    - by Angel S. Moreno
    Is there a good reason to put parent::__construct($config) in the construct of a CakePHP data source I am developing? I see it being used in some of the data sources found in https://github.com/cakephp/datasources/blob/master/models/datasources/amazon_associates_source.php but not sure why. I could just do private $_config = array(); function construct($config){ $this->_config = $config; } and access my $config the same way.

  • Is there a jQuery plugin for making a step-by-step type presentation?

    - by Earlz
    Hello, I was making a small thing in HTML and basically I have some "frames" like <div id="frame_1"> ... </div> <div id="frame_2"> ... </div> ... Basically what I want is for only one frame to be visible at one time and to navigate between frames easily with previous and next buttons (navigation by frame number a plus, but not required) Before I set out to write it myself I figured someone had already done it so has it been done?

  • Is there any solution or plug-in to automaticaly extract from text of email message data about a meeting and make a calendar item out of email

    - by user984532
    Emails often contain invitation to some event at some time on some day. In a single email it would be possible to smartly extract these data elements. In Outlook, one can make calendar item out of email by draging it to calendar - this saves time on the name of the calendar time and having all the details, but the user still has to manually pick time and date. Is there a smart solution so that a plug-in or add-on could do that?
