  • flash cs4 file reference. Event.COMPLETE not called on a MAC,

    - by jobbie jones
    Hi, I am working with a fileReference, however I'm having issues running on Safari on a MAC... EDIT The below example also doesnt work on Safari on a MAC... http://www.permadi.com/blog/2010/06/flash-as3-using-filereference-to-load-files-example-for-flash-cs4-and-above/ # The workflow on a PC runs as such: 1) Create file reference 2) attach addEventListener's for Event.SELECT and Event.COMPLETE 3) call the browse() method On a PC, Event.SELECT is fired when a file has been selected. Event.COMPLETE is fired when the file data is available to flash. If I select an 500meg file, it takes a few seconds before Event.COMPLETE is fired. If I attempt to access the file data properties (such as reading the data stream) before Event.COMPLETE is fired, I receive null reference errors... So far so good. However, on a MAC (speficially Safari, not tested other browsers), the Event.COMPLETE is not fired. I have checked the Adobe docs, which say Event.COMPLETE is fired when the upload is completed. So why does it get fired on windows when the fileReference has parsed the file, but the upload method has not yet been called... Can anyone help? Here's snippets of the code I am working on: public function browseFile(target:Object):void { var imagesFilter:FileFilter = new FileFilter("Allowed files", "*.jpg;*.bmp;*.flv;"); fileReference.browse([imagesFilter]); fileReference.addEventListener(Event.SELECT, fileSelect); fileReference.addEventListener(Event.COMPLETE, fileSelectComplete); } private function fileSelect(event:Event):void { // update label - IMPORTANT for large files as there's a delay while flash parses file, before control is handed back to this script... setStatusLabel("...loading file"); var fileReference:FileReference = event.target as FileReference; fileReference.addEventListener(Event.COMPLETE, fileSelectComplete); // load the file into the fileReference object fileReference.load(); } // Called when upload file has been processed by flash (a few secs for large files, or fileRef.data is null...) private function fileSelectComplete(event:Event):void { var fileReference:FileReference=event.target as FileReference; trace("ready to do things - but not fired on Safari on a MAC "); }

  • Trying to integrate CakePHP and jQuery

    - by user198003
    Trying to integrate CakePHP and jQuery, using next example http://bakery.cakephp.org/articles/view/dynamic-select-boxes-with-ajax-jquery What I want is to when user change first option element, to automaticly fill second select option box with proper values. But, nothing happens, if you can help me why. So, there is a Invoice add form (add.ctp), with next code... <?php echo $form->create('Invoice');?> <?php echo $javascript->link('jquery.js'); $category = array('1' => 'First', '4' => 'Fourth', '7' => 'Seventh'); echo $form->input('client_id', array('options' => $category, 'empty' => 'Choose:')); echo $form->select('clientBank_id', array("Choose category first"), null, null, false); ?> <script> $("#InvoiceClientId").change(function () { $.post('/invoices/listTitleByCategory/' + $(this).val(), function(data) { $("#InvoiceClientBankId").empty().append(data); }, 'html'); }) </script> Also, there is controller (invoices_controller.php): <?php var $name = 'Invoices'; var $helpers = array('Html', 'Form', 'Time', 'Number', 'Javascript'); var $paginate = array('order' => array('Invoice.pinned DESC', 'Invoice.invoiceNumber')); var $components = array('RequestHandler'); function beforeRender(){ // prevent useless warnings for Ajax if($this->RequestHandler->isAjax()){ Configure::write('debug', 0); } } // etc... function listTitleByCategory($category = "") { $this->layout = 'ajax'; $this->beforeRender(); $this->autoRender = false; $data = $this->Invoice->Client->find('list'); echo "<option value=0>just for testing...</option>"; foreach($data as $key => $val) { echo "<option value=$key>$val</option>"; } } ?> Please, if you can help me solving this.

  • printf anomaly after "fork()"

    - by pechenie
    OS: Linux, Language: pure C I'm moving forward in learning C progpramming in general, and C programming under UNIX in a special case :D So, I detected a strange (as for me) behaviour of the printf() function after using a fork() call. Let's take a look at simple test program: #include <stdio.h> #include <system.h> int main() { int pid; printf( "Hello, my pid is %d", getpid() ); pid = fork(); if( pid == 0 ) { printf( "\nI was forked! :D" ); sleep( 3 ); } else { waitpid( pid, NULL, 0 ); printf( "\n%d was forked!", pid ); } return 0; } In this case the output looks like: Hello, my pid is 1111 I was forked! :DHello, my pid is 1111 2222 was forked! Why the second "Hello" string occured in the child's output? Yes, it is exactly what the parent printed on it's start, with the parent's pid. But! If we place '\n' character in the end of each string we got the expected output: #include <stdio.h> #include <system.h> int main() { int pid; printf( "Hello, my pid is %d\n", getpid() ); // SIC!! pid = fork(); if( pid == 0 ) { printf( "I was forked! :D" ); //removed the '\n', no matter sleep( 3 ); } else { waitpid( pid, NULL, 0 ); printf( "\n%d was forked!", pid ); } return 0; } And the output looks like: Hello, my pid is 1111 I was forked! :D 2222 was forked! Why does it happen? Is it ... ummm ... correct behaviour? Or it's a kind of the 'bug'?

    I wrote a foreach loop for my datagridview to write all rows to txt file. I have a problem as it adds 2 empty lines at the end, as 1 row is full of empty cells after adding/reading to datagrid view. Is there any way to omit the last line or delete it in txt? foreach (DataGridViewRow item in this.DB.Rows) { foreach (DataGridViewCell item2 in item.Cells) { if(item2.Value != null) filewrite.Write(item2.Value.ToString() + " "); } filewrite.WriteLine(""); }

  • Use of text() function when using xPath in dom4j

    - by jlawless
    I have inherited an application that parses xml using dom4j and xPath: The xml being parsed is similar to the following: <cache> <content> <transaction> <page> <widget name="PAGE_ID">WRK_REGISTRATION</widget> <widget name="TRANS_DETAIL_ID">77145</widget> <widget name="GRD_ERRORS" /> </page> <page> <widget name="PAGE_ID">WRK_REGISTRATION</widget> <widget name="TRANS_DETAIL_ID">77147</widget> <widget name="GRD_ERRORS" /> </page> <page> <widget name="PAGE_ID">WRK_PROCESSING</widget> <widget name="TRANS_DETAIL_ID">77152</widget> <widget name="GRD_ERRORS" /> </page> </transaction> </content> </cache> Individual Nodes are being searched using the following: String xPathToGridErrorNode = "//cache/content/transaction/page/widget[@name='PAGE_ID'][text()='WRK_DNA_REGISTRATION']/../widget[@name='TRANS_DETAIL_ID'][text()='77147']/../widget[@name='GRD_ERRORS_TEMP']"; org.dom4j.Element root = null; SAXReader reader = new SAXReader(); Document document = reader.read(new BufferedInputStream(new ByteArrayInputStream(xmlToParse.getBytes()))); root = document.getRootElement(); Node gridNode = root.selectSingleNode(xPathToGridErrorNode); where xmlToParse is a String of xml similar to the excerpt provided above. The code is trying to obtain the GRD_ERROR node for the page with the PAGE_ID and TRANS_DETAIL_ID provided in the xPath. I am seeing an intermittent (~1-2%) failure (returned node is null) of this selectSingleNode request even though the requested node is in the xml being searched. I know there are some gotchas associated with using text()= in xPath and was wondering if there was a better way to format the xPath string for this type of search.

In short, how do I copy an SQLite database from file to memory using C# and System.Data.SQLite?

  • How to add new object to an IList mapped as a one-to-many with NHibernate?

    - by Jørn Schou-Rode
    My model contains a class Section which has an ordered list of Statics that are part of this section. Leaving all the other properties out, the implementation of the model looks like this: public class Section { public virtual int Id { get; private set; } public virtual IList<Static> Statics { get; private set; } } public class Static { public virtual int Id { get; private set; } } In the database, the relationship is implemented as a one-to-many, where the table Static has a foreign key pointing to Section and an integer column Position to store its index position in the list it is part of. The mapping is done in Fluent NHibernate like this: public SectionMap() { Id(x => x.Id); HasMany(x => x.Statics).Cascade.All().LazyLoad() .AsList(x => x.WithColumn("Position")); } public StaticMap() { Id(x => x.Id); References(x => x.Section); } Now I am able to load existing Statics, and I am also able to update the details of those. However, I cannot seem to find a way to add new Statics to a Section, and have this change persisted to the database. I have tried several combinations of: mySection.Statics.Add(myStatic) session.Update(mySection) session.Save(myStatic) but the closest I have gotten (using the first two statements), is to an SQL exception reading: "Cannot insert the value NULL into column 'Position'". Clearly an INSERT is attempted here, but NHibernate does not seem to automatically append the index position to the SQL statement. What am I doing wrong? Am I missing something in my mappings? Do I need to expose the Position column as a property and assign a value to it myself? EDIT: Apparently everything works as expected, if I remove the NOT NULL constraint on the Static.Position column in the database. I guess NHibernate makes the insert and immediatly after updates the row with a Position value. While this is an anwers to the question, I am not sure if it is the best one. I would prefer the Position column to be not nullable, so I still hope there is some way to make NHibernate provide a value for that column directly in the INSERT statement. Thus, the question is still open. Any other solutions?
