  • An image from byte to optimized web page presentation

    - by blgnklc
    I get the data of the stored image on database as byte[] array; then I convert it to System.Drawing.Image like the code shown below; public System.Drawing.Image CreateImage(byte[] bytes) { System.IO.MemoryStream memoryStream = new System.IO.MemoryStream(bytes); System.Drawing.Image image = System.Drawing.Image.FromStream(memoryStream); return image; } (*) On the other hand I am planning to show a list of images on asp.net pages as the client scrolls downs the page. The more user gets down and down on the page he/she does see the more photos. So it means fast page loads and rich user experience. (you may see what I mean on www.mashable.com, just take care the new loads of the photos as you scroll down.) Moreover, the returned imgae object from the method above, how can i show it in a loop dynamically using the (*) conditions above. Regards bk

  • How can I make a multi search SPROC/UDF by passing a tabled-value to it?

    - by Shimmy
    I actually want to achieve the following description This is the table argument I want to pass to the server <items> <item category="cats">1</item> <item category="dogs">2</item> </items> SELECT * FROM Item WHERE Item.Category = <one of the items in the XML list> AND Item.ReferenceId = <the corresponding value of that item xml element> --Or in other words: SELECT FROM Items WHERE Item IN XML according to the splecified columns. Am I clear enought? I don't mind to do it in a different way other than xml. What I need is selecting values that mach an array of two of its columns' values.

  • How to load secure S3 images into Flex with temporary URLs

    - by Yarin
    I have some secure images on S3 that I need to load into Flex. I was expecting to be able to do this using signed temporary URLs but can't get it working. I know the URLs I'm generating are correct, because they load fine in my browsers' address bar. Moreover, Flex has no problem loading my images with a non-signed url when they are public, but as soon as I try signing the urls all the images fail, whether public or not. I've tried image.source = signedURL, image.load(signedURL), etc. If I try loading the file with URLLoader/URLStream, it looks like I'm getting the data OK, but I'm not sure how to translate those results to an Image control. Is this just an issue with the Image control not being able to recognize signed urls? Do I have to load the image from a byte array? What would that look like?

  • PHP: OOP and methods

    - by Pirkka
    Hello I`ve been wondering how to implement methods in a class. Could someone explain me what means if one does OOP in procedural style? Here is an example: class Fld extends Model { private $file; private $properties = array(); public function init($file) { $this->file = $file; $this->parseFile(); } private function parseFile() { // parses the file foreach($this->file as $line)...... .................. $this->properties = $result; } } I mean is it a good thing to have methods like these that do operations for the class properties like that. Or should I pass the class property as method parameter... I mean this would cause error if the file property wouldnt be declared.

  • Reading a Delphi binary file in Python

    - by Brendan
    I have a file that was written with the following Delphi declaration ... Type Tfulldata = Record dpoints, dloops : integer; dtime, bT, sT, hI, LI : real; tm : real; data : array[1..armax] Of Real; End; ... Var: fh: File Of Tfulldata; I want to analyse the data in the files (many MB in size) using Python if possible - is there an easy way to read in the data and cast the data into Python objects similar in form to the Delphi records? Does anyone know of a library perhaps that does this?

  • C++ Microsoft SAPI: How to set Windows text-to-speech output to a memory buffer?

    - by Vladimir
    Hi all, I have been trying to figure out how to "speak" a text into a memory buffer using Windows SAPI 5.1 but so far no success, even though it seems it should be quite simple. There is an example of streaming the synthesized speech into a .wav file, but no examples of how to stream it to a memory buffer. In the end I need to have the synthesized speech in a char* array in 16 kHz 16-bit little-endian PCM format. Currently I create a temp .wav file, redirect speech output there, then read it, but it seems to be a rather stupid solution. Anyone knows how to do that? Thanks!

  • Understanding Ruby Enumerable#map (with more complex blocks)

    - by mstksg
    Let's say I have a function def odd_or_even n if n%2 == 0 return :even else return :odd end end And I had a simple enumerable array simple = [1,2,3,4,5] And I ran it through map, with my function, using a do-end block: simple.map do |n| odd_or_even(n) end # => [:odd,:even,:odd,:even,:odd] How could I do this without, say, defining the function in the first place? For example, # does not work simple.map do |n| if n%2 == 0 return :even else return :odd end end # Desired result: # => [:odd,:even,:odd,:even,:odd] is not valid ruby, and the compiler gets mad at me for even thinking about it. But how would I implement an equivalent sort of thing, that works?

  • iPhone / NSArray : How do I format a text file to be read in using arrayWithContentsOfFile

    - by nickthedude
    I have several large word lists and I had been loading them in place in the code as follows: NSArray *dict3 = [[NSArray alloc] initWithObjects:@"abled",@"about",@"above",@"absurd",@"absurdity", ... but now it is actually causing an exc_bad_access error weirdly, i know it seems implausible but for some reason IT IS causing it. (trust me on this I just spend the better part of a day debugging this crap) Anyway, I'm looking to get these humongous lines of code out of my files but I'm not sure what the best approach is. I guess I could do a plist but I need to figure out how to automate the process. it be easiest if I could just use the text files I've been compiling so if anyone knows how I can format the text file so that the myArray = [NSArray arrayWithContentsOfFile: @"myTextFile.txt"]; will be read in correctly as one word per element in the array it would really be appreciated. Thanks, Nick

  • Wordpress API: Add / Remove Tags on Posts

    - by st4ck0v3rfl0w
    I know it seems like a simple operation, but I can't find any resource or documentation that explains how to programmatically add and remove tags to a post using the post ID. Below is a sample of what I'm using, but it seems to overwrite all the other tags... function addTerm($id, $tax, $term) { $term_id = is_term($term); $term_id = intval($term_id); if (!$term_id) { $term_id = wp_insert_term($term, $tax); $term_id = $term_id['term_id']; $term_id = intval($term_id); } $result = wp_set_object_terms($id, array($term_id), $tax, FALSE); return $result; }

  • Why isnt php reading my cookie?

    - by Jason94
    at index.php i have a form to fill out some settings. the form posts to setsettings.php at setsettings.php it uses the form data and sets some cookies and redirect back to index.php. if i print_r($_COOKIE) at setsettings.php all is well. but nothing comes up at index.php, the $_COOKIE array is empty :( Does somebody know how i go about solving this? I set det setting by (setsettings.php): /* Write new cookie */ $expire = 60 * 60 * 24 * 60 + time(); // ~2 months setcookie("user_var_001", $_POST['selection'], $expire); and in index.php print_r($_COOKIE) turns up blank;

  • About enumerations in Delphi and c++ in 64-bit environments

    - by sum1stolemyname
    I recently had to work around the different default sizes used for enumerations in Delphi and c++ since i have to use a c++ dll from a delphi application. On function call returns an array of structs (or records in delphi), the first element of which is an enum. To make this work, I use packed records (or aligned(1)-structs). However, since delphi selects the size of an enum-variable dynamically by default and uses the smallest datatype possible (it was a byte in my case), but C++ uses an int for enums, my data was not interpreted correctly. Delphi offers a compiler switch to work around this, so the declaration of the enum becomes {$Z4} TTypeofLight = ( V3d_AMBIENT, V3d_DIRECTIONAL, V3d_POSITIONAL, V3d_SPOT ); {$Z1} My Questions are: What will become of my structs when they are compiled on/for a 64-bit environment? Does the default c++ integer grow to 8 Bytes? Are there other memory alignment / data type size modifications (other than pointers)?

  • Unsigned versus signed numbers as indexes

    - by simendsjo
    Whats the rationale for using signed numbers as indexes in .Net? In Python, you can index from the end of an array by sending negative numbers, but this is not the case in .Net. It's not easy for .Net to add such a feature later as it could break other code perhaps using special rules (yeah, a bad idea, but I guess it happens) on indexing. Not that I have ever have needed to index arrays over 2,147,483,647 in size, but I really cannot understand why they choose signed numbers. Can it be because it's more normal to use signed numbers in code?

  • SSIS process files from folder

    - by RT
    Background: I've a folder that gets pumped with files continuously. My SSIS package needs to process the files and delete them. The SSIS package is scheduled to run once every minute. I'm picking up the files in ascending order of file creation time. I'm building an array of files and then processing-deleting them one at a time. Problem: If an instance of my package takes longer than one minute to run, the next instance of the SSIS package will pick up some of the files the previous instance has in its buffer. By the time the second instance of teh package gets around to processing a file, it may already have been deleted by the first instance, creating an exception condition. I was wondering whether there was a way to avoid the exception condition. Thanks.

  • Why is EventListenerList traversed backwards in fireFooXXX()?

    - by Joonas Pulakka
    I don't understand the rationale of this code, taken from javax.swing.event.EventListenerList docs: protected void fireFooXXX() { // Guaranteed to return a non-null array Object[] listeners = listenerList.getListenerList(); // Process the listeners last to first, notifying // those that are interested in this event for (int i = listeners.length-2; i>=0; i-=2) { if (listeners[i]==FooListener.class) { // Lazily create the event: if (fooEvent == null) fooEvent = new FooEvent(this); ((FooListener)listeners[i+1]).fooXXX(fooEvent); } } } Why is the list traversed backwards? Why is only every second listener called? The event firing is implemented exactly this way in javax.swing.tree.DefaultTreeModel among others, so it's obviously me who's just not getting something.

  • When I'm iterating over two arrays at once, which one do I use as the limit?

    - by Martijn Courteaux
    Hi, I'm always struggling with something like the following Java example: String breads[] = {"Brown", "White", "Sandwich"}; int count[] = new int[breads.length]; for (int i = 0; i < ****; i++) { // Prompt the number of breads } ****: which array.length should I choose? I can choose between breads.length and count.length I know it would be the same result, but I don't know which one I shoud choose. There are many other examples where I get the same problem. I'm sure that you have encountered this problem as well in the past. What should you choose? Are there general agreements? Thanks

  • database table in Magento does not exist: sales_flat_shipment_grid

    - by dene
    We're using Magento 1.4.0.1 and want to use an extension from a 3rd party developer. The extension does not work, because of a join to the table "sales_flat_shipment_grid": $collection = $model->getCollection()->join('sales/shipment_grid', 'increment_id=shipment', array('order_increment_id'=>'order_increment_id', 'shipping_name' =>'shipping_name'), null,'left'); Unfortunately this table does not exist n our database. So the error "Can't retrieve entity config: sales/shipment_grid" appears. If I comment this part out, the extension is working, but I guess, it does not proper work. Does anybody know something about this table? There are a backend-option for the catalog to use the "flat table" option, but this is only for the catalog. And the tables already exists, no matter which option is checked. Thank you a lot! :-)

  • How do I do multiple assignment in MATLAB?

    - by Benjamin Oakes
    Here's an example of what I'm looking for: >> foo = [88, 12]; >> [x, y] = foo; I'd expect something like this afterwards: >> x x = 88 >> y y = 12 But instead I get errors like: ??? Too many output arguments. I thought deal() might do it, but it seems to only work on cells. >> [x, y] = deal(foo{:}); ??? Cell contents reference from a non-cell array object. How do I solve my problem? Must I constantly index by 1 and 2 if I want to deal with them separately?

  • Async call Objective C iphone

    - by Sam
    Hi guys, I'm trying to get data from a website- xml. Everything works fine. But the UIButton remains pressed until the xml data is returned and thus if theres a problem with the internet service, it cant be corrected and the app is virtually unusable. here are the calls: { AppDelegate *appDelegate = (AppDelegate *)[[UIApplication sharedApplication] delegate]; if(!appDelegate.XMLdataArray.count > 0){ [UIApplication sharedApplication].networkActivityIndicatorVisible = YES; [appDelegate GetApps]; //function that retrieves data from Website and puts into the array - XMLdataArray. } XMLViewController *controller = [[XMLViewController alloc] initWithNibName:@"MedGearsApps" bundle:nil]; [self.navigationController pushViewController:controller animated:YES]; [controller release]; } It works fine, but how can I make the view buttons functional with getting stuck. In other words, I just want the UIButton and other UIButtons to be functional whiles the thing works in the background. I heard about performSelectorInMainThread but i cant put it to practice correctly any help is appreciated :)

  • Possible to add javascript to Zend_Form_Element_Radio?

    - by Stepppo
    Ultimately, I'd like my Zend Form to render this HTML: <p>Do you have any documents to upload?</p> <p>Yes <input type="radio" value="Yes" name="uploadChoice" onClick="showTable()">&nbsp;&nbsp;No <input type="radio" value="No" name="uploadChoice" onClick="hideTable()" checked></p> Here's what I have in my Zend_Form: //create radio buttons $uploadQuestion = new Zend_Form_Element_Radio('upLoadQuestion'); $uploadQuestion->setLabel('Do you have any documents to upload?') ->addMultiOptions(array( 'yes' => 'Yes', 'no' => 'No' )) ->setSeparator(' '); The problem I'm running into is how to add the onClick="showTable()" and onClick="hideTable()" elements to their respective radio buttons. In the alternative, I could rework the javascript and add something like onClick="toggleTable()" to the radio buttons if I can't add something different to each of the radio buttons. But, will Zend let me do that?
