  • Concatenating databases with Squeryl

    - by Pengin
    I'm trying to use Squeryl to take the contents of a table from one database, and append it to the equivalent table in another database. The primary key will have to be reassigned in the process, but I'm getting the error NULL not allowed for column "SIMID". Why is this? object Concatenator { def main(args: Array[String]) { Class.forName("org.h2.Driver"); val seshA = Session.create( java.sql.DriverManager.getConnection("jdbc:h2:file:data/resultsA", "sa", "password"), new H2Adapter ) val seshB = Session.create( java.sql.DriverManager.getConnection("jdbc:h2:file:data/resultsB", "sa", "password"), new H2Adapter ) using(seshA){ import Library._ from(sims){s => select(s)}.foreach{item => using(seshB){ sims.insert(item); } } } } case class Simulation( @Column("SIMID") var id: Long, val date: Date ) extends KeyedEntity[Long] object Library extends Schema { val sims = table[Simulation] on(sims)(s => declare( s.id is(unique, indexed, autoIncremented) )) } }

  • strategy for observer pattern?

    - by fayer
    I want to use observer pattern for a logging system. We have got logObservers and logObservables. The class that will have to log something will implement iLogObservable and include these methods: private $logObservers = array(); public function addLogObserver($logObserver) { $this->logObservers[] = $logObserver; } public function removeLogObserver($logObserver) { $this->logObservers[] = $logObserver; } public function write($type, $message) { foreach($this->logObservers as $logObserver) { $logObserver->log($level, $message); ; } } Then I noticed, that a lot of classes that will use logging will have these methods and I have to copy paste. So isn't it better to have these methods in a class I call LogObservable or just Log and then use strategy (instantiate this class inside all classes that will have to log). When I change the methods in Log, all logObservables will be affected. However, I have not seen anyone use observer pattern with strategy pattern yet, but it seems to be very efficient and remove the duplications. What do you think?

  • How to print element values when iterating through XML document in PHP

    - by pharma_joe
    I am iterating through the results of a service call to yahoo news thus: //Send service request if (!$yahooResults = file_get_contents($yahooRequest)) { echo 'Error processing service request'; } //Read result into xml document $yahooResultXml = new DOMDocument('1.0', 'UTF-8'); $yahooResultXml-loadXML($yahooResults); //Build page include_once('components/pageHeader.php'); echo 'Search Results'; //echo $yahooResultXml-saveHTML(); //Iterate over each Result node $stories = $yahooResultXml-getElementsByTagName('Result'); foreach ($stories as $story) { //Title //Summary //Url //Source //Language //Publish Date //Modification Date } include_once('components/pageFooter.php'); Each Title is in a Title node within a Result Node. I cannot figure out how to simply echo the content of the Title node!

  • What's the best example of pure show-off code you've seen?

    - by Damovisa
    Let's face it, programmers can be show-offs. I've seen a lot of code that was only done a particular way to prove how smart the person who wrote it was. What's the best example of pure show-off code you've seen (or been responsible for) in your time? For me, it'd have to be the guy who wrote FizzBuzz in one line on a whiteboard during a programming interview. Not really that impressive in the scheme of things, but completely unnecessary and pure, "look-what-I-can-do". I've lost the original code, but I think it was something like this (linebreaks for readability): Enumerable.Range(1,100).ToList().ForEach( n => Console.WriteLine( (n%3==0) ? (n%5==0) ? "FizzBuzz" : "Fizz" : (n%5==0) ? "Buzz" : n ) );

  • Find order of data inside an array

    - by user271619
    I have a simple array of stuff: $array = array("apples","oranges","strawberries"); I am trying to find the order of the stuff inside the array. (sometimes the order changes, and so do the items) I'm expecting to get something like this: "apples" = 0, "oranges = 1, "strawberries = 2 The end result has something to do with database sorting. Something like this, inside a foreach loop: UPDATE tbl SET sortorder = $neworder WHERE fruit = '$fruitname' The $neworder variable would be populated with the new order, inside the array. While the $fruit variable comes from the item inside the array.

  • Work time in fullcalendar [Solution]

    - by Zozo
    Full calendar have no included options to work-time feature (selecting first and last rows in agenda view for any day - where in example company is not working). I managed something like that: viewDisplay: function(view){ $.ajax({ url: 'index.php?r=calendar/Default/worktime', dataType: 'json', success: function(data){ if(view.name=='agendaWeek') selectWorkTime(data, 30, 0, 24, false); else if(view.name=='agendaDay') selectDayWorkTime(data, 30, 0, 24, view, false); } }); } Where index.php?r=calendar/Default/worktime is php file returning json. It looks like that: $arr = array( 'mon' => array('8:00', '17:00'), 'tue' => array('9:00', '15:00'), 'wed' => array('9:30', '19:00'), 'thu' => array('6:00', '14:00'), 'fri' => array('0:00', '24:00'), 'sat' => array('9:00', '14:00'), 'sun' => array() ); foreach ($arr as &$day){ foreach($day as &$hour){ $tmp = explode(':', $hour); $hour = $tmp[0] * 3600 + $tmp[1] * 60; } } print json_encode($arr); and at the end, some functions using for counting and selecting work-time: function selectDayWorkTime(timeArray, slotMinutes, minTime, maxTime, viewObject, showAtHolidays){ var dayname; $('.fc-content').find('.fc-view-agendaWeek').find('.fc-agenda-body') .children('.fc-work-time').remove(); $('.fc-content').find('.fc-view-agendaDay') .find('.fc-work-time-day').removeClass('fc-work-time-day'); switch(viewObject.start.getDay()){ case 1: dayname='mon'; break; case 2: dayname='tue'; break; case 3: dayname='wed'; break; case 4: dayname='thu'; break; case 5: dayname='fri'; break; case 6: dayname='sat'; break; case 0: dayname='sun'; break; } for(var day in timeArray){ if(day == dayname){ if($('.fc-content').find('.fc-view-agendaDay').find('.fc-'+day).attr('class').search('fc-holiday') == -1 || showAtHolidays){ var startBefore = 0; var endBefore = timeArray[day][0] / (60 * slotMinutes) - (minTime * 60) / slotMinutes; var startAfter = timeArray[day][1] / (60 * slotMinutes) - (minTime * 60) / slotMinutes; var endAfter = (maxTime - minTime) * 60 / slotMinutes - 1; for(startBefore; startBefore < endBefore; startBefore++){ $('.fc-view-agendaDay').find('.fc-slot'+startBefore).find('div').addClass('fc-work-time-day'); } for(startAfter; startAfter <= endAfter; startAfter++){ $('.fc-view-agendaDay').find('.fc-slot'+startAfter).find('div').addClass('fc-work-time-day'); } } } } } function selectWorkTime(timeArray, slotMinutes, minTime, maxTime, showAtHolidays){ for(var day in timeArray){ var startBefore = 0; var endBefore = timeArray[day][0] / (60 * slotMinutes) - (minTime * 60) / slotMinutes; var startAfter = timeArray[day][1] / (60 * slotMinutes) - (minTime * 60) / slotMinutes; var endAfter = (maxTime - minTime) * 60 / slotMinutes - 1; if(startBefore > endBefore) endBefore = startBefore; if(startAfter > endAfter) startAfter = endAfter; try{ selectCell(startBefore, endBefore, 'fc-'+day, 'fc-work-time', false, showAtHolidays); selectCell(startAfter, endAfter, 'fc-'+day, 'fc-work-time', true, showAtHolidays); } catch(e){ continue; } } } function selectCell(startRowNo, endRowNo, collClass, cellClass, closeGap, showAtHolidays){ $('.fc-content').find('.fc-view-agendaWeek').find('.fc-agenda-body') .children('.'+cellClass+''+startRowNo+''+collClass).remove(); $('.fc-content').find('.fc-view-agendaDay') .find('.fc-work-time-day').removeClass('fc-work-time-day'); if($('.fc-content').find('.fc-view-agendaWeek').find('.'+collClass).attr('class').search('fc-holiday') == -1 || showAtHolidays){ var width = $('.fc-content').find('.fc-view-agendaWeek') .find('.'+collClass+':last').width(); var height = 0; if(closeGap && (startRowNo != endRowNo)){ height = $('.fc-content').find('.fc-view-agendaWeek') .find('.fc-slot'+ startRowNo).height(); } $('.fc-view-agendaWeek').find('.fc-agenda-body').prepend('<div class="'+cellClass+' ' + ''+cellClass+''+startRowNo+''+collClass+'"></div>'); $('.'+cellClass).width(width - 2); height += $('.fc-content').find('.fc-view-agendaWeek') .find('.fc-slot'+ endRowNo).position().top - $('.fc-content').find('.fc-view-agendaWeek') .find('.fc-slot'+ startRowNo).position().top; $('.'+cellClass+''+startRowNo+''+collClass).height(height); $('.'+cellClass+''+startRowNo+''+collClass) .css('margin-top', $('.fc-content').find('.fc-view-agendaWeek') .find('.fc-slot'+ startRowNo).position().top); $('.'+cellClass+''+startRowNo+''+collClass) .css('margin-left', $('.fc-content').find('.fc-view-agendaWeek') .find('.'+collClass+':last').offset().left - width / 2); } } Don't forget about CSS: .fc-work-time-day{ background-color: yellow; opacity: 0.3; filter: alpha(opacity=30); /* for IE */ } .fc-work-time{ position: absolute; background-color: yellow; z-index:10; margin: 0; padding: 0; text-align: left; z-index: 0; opacity: 0.3; filter: alpha(opacity=30); /* for IE */ } So, I've got some questions about - is the other way to make the same, but no using absolute div's in agendaWeek? And... How can I get in viewDisplay function actual slotMinutes, minTime and maxTime

  • Sending mass email using PHP

    - by Alan
    I am currently writing a music blog. The administrator posts a new article every 2-3 days. Once the administrator posts an article, a mass email will be sent to around 5000 subscribers immediately. What is the best way to implement the mass mail feature? Does the following function work? function massmail() { $content = '...'; foreach ($recipients as $r) { $_content = $content . '<img src="http://xxx/trackOpenRate.php?id='.$r.'">'; mail($r, 'subject', $_content); } } Another question: If all 5000 subscribers are using Yahoo Mail, will Yahoo treat it as a DDOS attack and block the IP address of my SMTP server?

  • Twitter Trends API weekly.json causing error "Cannot use object of type stdClass as array"

    I have the following PHP code: $ch = curl_init(); curl_setopt($ch, CURLOPT_URL,$URL); curl_setopt($ch, CURLOPT_RETURNTRANSFER,1); $result = curl_exec($ch); curl_close($ch); $obj = json_decode($result); foreach ($obj[0]->trends as $trend) echo utf8_decode($trend->name); which works fine for URL #1 (into the variable $URL): http://api.twitter.com/1/trends/1.json?exclude=hashtags but causes an error "Cannot use object of type stdClass as array" for URL #2: http://api.twitter.com/1/trends/weekly.json?exclude=hashtags I have searched for a while, but can't figure out a code to fix this and handle both URLs. Any help would be much appreciated.

  • F# Extention Methods on Lists, IEnumberable, etc

    - by flevine100
    I have searched StackOverflow (and other sources) for this answer, but can't seem to find anything. In C#, if I had a widget definition, say: class widget { public string PrettyName() { ... do stuff here } } and I wanted to allow for easy printing of a list of Widgets, I might do this: namespace ExtensionMethods { public static PrintAll( this IEnumerable<Widget> widgets, TextWriter writer ) { foreach(var w in widgets) { writer.WriteLine( w.PrettyName() ) } } } How would I accomplish something similar with a record type and a collection (List or Seq preferrably in F#). I'd love to have a list of Widgest and be able to call a function right on the collection that did something like this. Assume (since it's F#) that the function would not be changing the state of the collection that it's attached to, but returning some new value.

  • StreamWriter stops writing when file is opened from web link

    - by fearofawhackplanet
    Following on from my previous question... The following code creates log files on a web server: private void LogMessage(Message msg) { using (StreamWriter sw = File.AppendText(_logDirectory + DateTime.Now.ToString("yyyyMMddHH") + ".txt")) { sw.WriteLine(msg.ToString()); } } The log files are linked to from an admin page on the web site: foreach (FileInfo file in logDir.GetFiles()) { Response.Write("<a href='http:// .... /Logs/" + file.Name + "'>" + file.Name + "</a>"); } I'm getting the problem that after someone looks at one of the log files from the link, that log file stops being written to.

    - by maxp
    Say i have the following xml file: <a> <b> <c></c> </b> <b> <c></c> </b> </a> var nodes = doc.SelectNodes("/a/b"); will select the two b nodes. I then loop these two nodes suchas: foreach (XmlNode node in nodes) { } However, when i call node.SelectNodes("/a/b/c"); It still returns both values and not just the descendants. Is it possible to select nodes only descening from the current node?

  • Online Image Slideshow Question. File Access Problems.

    - by msandbot
    Hi, I have a flash .swf file that I embed on my webpage. On my server I have the .swf file and multiple image folders. I would like to load every file in one of those folders into the flash slideshow. How should I go about doing this? I tried used Air but it doesn't work on my system as an application so I doubt it will work online. Eventually I plan on making a menu where you can select different folders to display and since they are of different sizes, a foreach loop would be optimal. Keeping a txt file with the number of images is also possible if theres a way to read that in, but I would prefer the more dynamic approach. I am working towards using php for the website if that helps find a solution. Thanks, -Mike Also my slideshow works great online currently but i have to hardcode in the number of files.

  • Using C# Type as generic

    - by I Clark
    I'm trying to create a generic list from a specific Type that is retrieved from elsewhere: Type listType; // Passed in to function, could be anything var list = _service.GetAll<listType>(); However I get a build error of: The type or namespace name 'listType' could not be found (are you missing a using directive or an assembly reference?) Is this even possible or am I setting foot onto C# 4 Dynamic territory? As a background: I want to automatically load all lists with data from the repository. The code below get's passed a Form Model whose properties are iterated for any IEnum (where T inherits from DomainEntity). I want to fill the list with objects of the Type the list made of from the repository. public void LoadLists(object model) { foreach (var property in model.GetType() .GetProperties(BindingFlags.Public | BindingFlags.Instance | BindingFlags.SetProperty)) { if (IsEnumerableOfNssEntities(property.PropertyType)) { var listType = property.PropertyType.GetGenericArguments()[0]; var list = _repository.Query<listType>().ToList(); property.SetValue(model, list, null); } } }

  • Optimal way to generate list of PHP object properties with delimiter character, implode()?

    - by Kris
    I am trying to find out if there is a more optimal way for creating a list of an object's sub object's properties. (Apologies for the crude wording, I am not really much of an OO expert) I have an object "event" that has a collection of "artists", each artist having an "artist_name". On my HTML output, I want a plain list of artist names delimited by a comma. PHP's implode() seems to be the best way to create a comma delimited list of values. I am currently iterating through the object and push values in a temporary array "artistlist" so I can use implode(). That is the shortest I could come up with. Is there a way to do this more elegant? $artistlist = array(); foreach ($event->artists as $artist) { $artistlist[] = $artist->artist_name; } echo implode(', ', $artistlist);

  • How To Get Type Info Without Using Generics?

    - by DaveDev
    Hi Guys I have an object obj that is passed into a helper method. public static MyTagGenerateTag<T>(this HtmlHelper htmlHelper, T obj /*, ... */) { Type t = typeof(T); foreach (PropertyInfo prop in t.GetProperties()) { object propValue = prop.GetValue(obj, null); string stringValue = propValue.ToString(); dictionary.Add(prop.Name, stringValue); } // implement GenerateTag } I've been told this is not a correct use of generics. Can somebody tell me if I can achieve the same result without specifying a generic type? If so, how? I would probably change the signature so it'd be like: public static MyTag GenerateTag(this HtmlHelper htmlHelper, object obj /*, ... */) { Type t = typeof(obj); // implement GenerateTag } but Type t = typeof(obj); is impossible. Any suggestions? Thanks Dave

  • PHP Dynamic Breadcrumb

    Hello, I got this code from someone and it works very well, I just want to remove the link from the last element of the array: //get rid of empty parts $crumbs = array_filter($crumbs); $result = array(); $path = ''; foreach($crumbs as $crumb){ $path .= '/' . $crumb; $name = ucfirst(str_replace(array(".php","_"),array(""," "), $crumb)); $result[] = "<a href=\"$path\">$name</a>"; } print implode(' > ', $result); This will output for example: Content Common File I just want a to remove the link from the last item - "File" to be just plain text.. I tried myself to count the array items and then if the array item is the last one then to print as plain text the last item.. but I'm still noob, I haven't managed to get a proper result.. Thank you!

  • C# method generic params parameter bug?

    - by Mike M
    Hey, I appears to me as though there is a bug/inconsistency in the C# compiler. This works fine (first method gets called): public void SomeMethod(string message, object data); public void SomeMethod(string message, params object[] data); // .... SomeMethod("woohoo", item); Yet this causes "The call is ambiguous between the following methods" error: public void SomeMethod(string message, T data); public void SomeMethod(string message, params T[] data); // .... SomeMethod("woohoo", (T)item); I could just use the dump the first method entirely, but since this is a very performance sensitive library and the first method will be used about 75% of the time, I would rather not always wrap things in an array and instantiate an iterator to go over a foreach if there is only one item. Splitting into different named methods would be messy at best IMO. Thoughts?

  • In WPF using a ListView is there an elegant way to auto resize items?

    - by Justin
    I recently wrote, my first, WPF application that has a list of items that are polled from a web-serivce. The items are displayed/data-bound in a ListView via a GridView. A background thread periodically polls the web-serivce and updates the list. If, say, I had three items initially bound to the ListView that simply display a description and the three descriptions where something like: - ProjectA - ProjectB - ProjectC Later a new item is added with a description of 'AReallyReallyLongProjectName', I would end up with a list like: - ProjectA - ProjectB - ProjectC - AReallyR The GridViewColumn would not update it's width and would subsequently cut off any new items that extended the original width. I added this bit of code which forces the column to resize, but it just seems a little hacky. (Just seems weird to set a width just to set it back to nothing to force the resize) if(gridView != null) { foreach(var column in gridView.Columns) { if (double.IsNaN(column.Width) column.Width = column.ActualWidth; column.Width = double.NaN; } } Is there a better, more elegant solution, to accomplish this same thing?

  • Delete from array help

    I have a cookie which stores info in an array. This is for a classifieds website, and whenever users delete their 'ads' the cookie must also be removed of the ad which was deleted.
