  • In Javascript, how to avoid NaN when adding arrays

    - by Jonas
    I'm trying to add the values of two arrays in javascript eg. [1,2,1] + [3,2,3,4] The answer should be 4,4,4,4 but I'm either getting 4,4,4 or 4,4,4,NaN if I change the 1st array length to 4. I know a 4th number needs to be in the 1st array, but i can't figure out how to tell javascript to make it 0 rather then undefined if there is no number.

  • How to ANSI-C cast from unisigned int * to char *?

    - by user314290
    I want these two print functions to do the same thing: unsigned int Arraye[] = {0xffff,0xefef,65,66,67,68,69,0}; char Arrage[] = {0xffff,0xefef,65,66,67,68,69,0}; printf("%s", (char*)(2+ Arraye)); printf("%s", (char*)(2+ Arrage)); where Array is an unsigned int. Normally, I would change the type but, the problem is that most of the array is numbers, although the particular section should be printed as ASCII.

  • Publish to Facebook Stream via PHP using Graph API

    - by Liquid
    I'm trying to post a message to a user's wall using the new graph API and PHP. Connection seems to work fine, but no post appears. I'm not sure how to set up the posting code correctly. Please help me out. Sorry for the broken-looking code, for some reason StackOverflow didn't want to close it all in the code block. Below is my full code. Am I missing an extender permission requests, or is that taken care in this code: PHP Code <?php include_once 'facebook.php'; $facebook = new Facebook(array( 'appId' => 'xxxxxxxxxxxxxxxxxx', 'secret' => 'xxxxxxxxxxxxxxxxxxxxxxxxxx', 'cookie' => true )); $session = $facebook->getSession(); if (!$session) { $url = $facebook->getLoginUrl(array( 'canvas' => 1, 'fbconnect' => 0 )); echo "<script type='text/javascript'>top.location.href = '$url';</script>"; } else { try { $uid = $facebook->getUser(); $me = $facebook->api('/me'); $updated = date("l, F j, Y", strtotime($me['updated_time'])); echo "Hello " . $me['name'] .

  • How do I use ViewScripts on Zend_Form File Elements?

    - by Sonny
    I am using this ViewScript for my standard form elements: <div class="field" id="field_<?php echo $this->element->getId(); ?>"> <?php if (0 < strlen($this->element->getLabel())) : ?> <?php echo $this->formLabel($this->element->getName(), $this->element->getLabel());?> <?php endif; ?> <span class="value"><?php echo $this->{$this->element->helper}( $this->element->getName(), $this->element->getValue(), $this->element->getAttribs() ) ?></span> <?php if (0 < $this->element->getMessages()->length) : ?> <?php echo $this->formErrors($this->element->getMessages()); ?> <?php endif; ?> <?php if (0 < strlen($this->element->getDescription())) : ?> <span class="hint"><?php echo $this->element->getDescription(); ?></span> <?php endif; ?> </div> Trying to use that ViewScript alone results in an error: Exception caught by form: No file decorator found... unable to render file element Looking at this FAQ revealed part of my problem, and I updated my form element decorators like this: 'decorators' => array( array('File'), array('ViewScript', array('viewScript' => 'form/field.phtml')) ) Now it's rendering the file element twice, once within my view script, and extra elements with the file element outside my view script: <input type="hidden" name="MAX_FILE_SIZE" value="8388608" id="MAX_FILE_SIZE" /> <input type="hidden" name="UPLOAD_IDENTIFIER" value="4b5f7335a55ee" id="progress_key" /> <input type="file" name="upload_file" id="upload_file" /> <div class="field" id="field_upload_file"> <label for="upload_file">Upload File</label> <span class="value"><input type="file" name="upload_file" id="upload_file" /></span> </div> Any ideas on how to handle this properly with a ViewScript?

  • Transferring binary data through a SOAP webservice? C# / .NET

    - by Jason
    I have a webservice that returns the binary array of an object. Is there an easier way to transfer this with SOAP or does it need to be contained in XML? It's working, but I had to increase the send and receive buffer to a large value. How much is too much? Transferring binary in XML as an array seems really inefficient, but I can't see any way to add a binary attachment using .NET.
