  • Best way of implementing DropDownList in ASP.NET MVC 2?

    - by Kelsey
    I am trying to understand the best way of implementing a DropDownList in ASP.NET MVC 2 using the DropDownListFor helper. This is a multi-part question. First, what is the best way to pass the list data to the view? Pass the list in your model with a SelectList property that contains the data Pass the list in via ViewData How do I get a blank value in the DropDownList? Should I build it into the SelectList when I am creating it or is there some other means to tell the helper to auto create an empty value? Lastly, if for some reason there is a server side error and I need to redisplay the screen with the DropDownList, do I need to fetch the list values again to pass into the view model? This data is not maintained between posts (at least not when I pass it via my view model) so I was going to just fetch it again (it's cached). Am I going about this correctly?

    - by vaibhav
    I have never used UDF in sql server. Today I got to know that we can have functions which can return a table. So I just wanted to know can I use functions in place of views. If yes, which one is the better choice and why

  • Customer session is different in different parts of a Magento website

    - by Josh Pennington
    I have a function inside of a Helper in Magento that returns whether or not a customer attribute equals one. Here is my Helper class class Nie_Nie_Helper_Data extends Mage_Core_Helper_Abstract { public function isNieAdmin() { if(Mage::getSingleton('customer/session')->getCustomer()->getNieAdmin() == 1) { return true; } else { return false; } } } Now when I call this function from a class that extends Mage_Core_Block_Template, everything seems to work fine. However when I try to use this inside one of my controllers, it does not work. In fact when I do Mage::getSingleton('customer/session')-getCustomer()-debug() the only variable that is returned is the website_id. Does anyone know what I have to do in order to get this to work? Thanks Josh Pennington

  • What to put in a python module docstring?

    - by 007brendan
    Ok, so I've read both PEP 8 and PEP 257, and I've written lots of docstrings for functions and classes, but I'm a little unsure about what should go in a module docstring. I figured, at a minimum, it should document the functions and classes that the module exports, but I've also seen a few modules that list author names, copyright information, etc. Does anyone have an example of how a good python docstring should be structured?

  • AJAX with Ruby on Rails?

    - by Zachary
    This is probably a really dumb question with a simple answer but... I am working on a project where I need to use AJAX to send/receive information. I am using Ruby on Rails (which I am pretty new to), but rather than using the helper methods or the built in functionality in the 'defaults' Javascript file, I need to do this manually in my own Javascript. I believe that ultimately I will want to send a request with a JSON object, then have the controller return another JSON object containing the requested information. The problem is that I cannot seem to find the syntax for sending something to a specific controller method, with parameters, directly from Javascript - everything I Google ends up being tutorials for using the Rails AJAX helper methods.

  • How to clean and simplify this code?

    - by alkalim
    After thinking about This Question and giving an answer to it I wanted to do more about that to train myself. So I wrote a function which will calc the length of an given function. Th given php-file has to start at the beginning of the needed function. Example: If the function is in a big phpfile with lots of functions, like /* lots of functions */ function f_interesting($arg) { /* function */ } /* lots of other functions */ then $part3 of my function will require to begin like that (after the starting-{ of the interesting function): /* function */ } /* lots of other functions */ Now that's not the problem, but I would like to know if there are an cleaner or simplier ways to do this. Here's my function: (I already cleaned a lot of testing-echo-commands) (The idea behind it is explained here) function f_analysis ($part3) { if(isset($part3)) { $char_array = str_split($part3); //get array of chars $end_key = false; //length of function $depth = 0; //How much of unclosed '{' $in_sstr = false; //is next char inside in ''-String? $in_dstr = false; //is nect char inside an ""-String? $in_sl_comment = false; //inside an //-comment? $in_ml_comment = false; //inside an /* */-comment? $may_comment = false; //was the last char an '/' which can start a comment? $may_ml_comment_end = false; //was the last char an '*' which may end a /**/-comment? foreach($char_array as $key=>$char) { if($in_sstr) { if ($char == "'") { $in_sstr = false; } } else if($in_dstr) { if($char == '"') { $in_dstr = false; } } else if($in_sl_comment) { if($char == "\n") { $in_sl_comment = false; } } else if($in_ml_comment) { if($may_ml_comment_end) { $may_ml_comment_end = false; if($char == '/') { $in_ml_comment = false; } } if($char == '*') { $may_ml_comment_end = true; } } else if ($may_comment) { if($char == '/') { $in_sl_comment = true; } else if($char == '*') { $in_ml_comment = true; } $may_comment = false; } else { switch ($char) { case '{': $depth++; break; case '}': $depth--; break; case '/': $may_comment = true; break; case '"': $in_dstr = true; break; case "'": $in_sstr = true; break; } } if($depth < 0) { $last_key = $key; break; } } } else echo '<br>$part3 of f_analysis not set!'; return ($last_key===false) ? false : $last_key+1; //will be false or the length of the function }

  • drupal jQuery 1.4 on specific pages

    - by Mark
    I'm looking for a way to force drupal to use 1.4 on specific pages. This is the same as this old question:http://stackoverflow.com/questions/2842792/drupal-jquery-1-4-on-specific-pages It look me a while to try the answer which I marked correct. But because I'm new to module dev overall I couldn't figure it out based on the answer. The code from that answer looked like this: /** * Implementation of hook_theme_registry_alter(). * Based on the jquery_update module. * * Make this page preprocess function runs *last*, * so that a theme can't call drupal_get_js(). */ function MYMODULE_theme_registry_alter(&$theme_registry) { if (isset($theme_registry['page'])) { // See if our preprocess function is loaded, if so remove it. if ($key = array_search('MYMODULE_preprocess_page', $theme_registry['page']['preprocess functions'])) { unset($theme_registry['page']['preprocess functions'][$key]); } // Now add it on at the end of the array so that it runs last. $theme_registry['page']['preprocess functions'][] = 'MYMODULE_preprocess_page'; } } /** * Implementation of moduleName_preprocess_hook(). * Based on the jquery_update module functions. * * Strips out JS and CSS for a path. */ function MYMODULE_preprocess_page(&$variables, $arg = 'my_page', $delta=0) { // I needed a one hit wonder. Can be altered to use function arguments // to increase it's flexibility. if(arg($delta) == $arg) { $scripts = drupal_add_js(); $css = drupal_add_css(); // Only do this for pages that have JavaScript on them. if (!empty($variables['scripts'])) { $path = drupal_get_path('module', 'admin_menu'); unset($scripts['module'][$path . '/admin_menu.js']); $variables['scripts'] = drupal_get_js('header', $scripts); } // Similar process for CSS but there are 2 Css realted variables. // $variables['css'] and $variables['styles'] are both used. if (!empty($variables['css'])) { $path = drupal_get_path('module', 'admin_menu'); unset($css['all']['module'][$path . '/admin_menu.css']); unset($css['all']['module'][$path . '/admin_menu.color.css']); $variables['styles'] = drupal_get_css($css); } } } I need the jquery_update 1.3.2 to be unset on the node-types of 'blog' and 'video'. Can someone help me out? Thank you.

I put the require('blog/wp-blog-header.php') in my index.php file(ci) on the root. Any idea where I am messing up?

  • Android files manipulation

    - by klaus-vlad
    Hi, Through the housekeeping stuff my android application has to do is to read and write some files and sometimes to delete others and create new ones. The files in cause have all "sdcard/" as root. Is it safe if I perform all this task using Java style functions ? To me it is very handy to do it this way but I've read that not always the java functions can be applied when it comes to files in Android.

  • write javascript function

    - by sunglim
    I used to write javascript functions Utility = function (){}; Utility.SwapMember = function(name,id){ return ... }; Utility.GetCommnaNo = function(originalNo){ return ... }; .. alert(Utility.GetCommnaNo(totalCnt)); it's quite a bit nice way to make functions get together. But I think there must be better way. do you have any better way?

  • Can a math intensive application cause a crash?

    - by philcolbourn
    I have been messing with hash functions and functions to generate primes etc. I had 3 lock-ups in a short period. This was odd since my macbook rarely locks-up and usually only when I run out of memory - which does not happen often. But in this case, I had three in a row and none since (but I also am not generating as much load as before).

  • Interface helpers or delegating interface parent

    - by Craig Peterson
    If I have an existing IInterface descendant implemented by a third party, and I want to add helper routines, does Delphi provide any easy way to do so without redirecting every interface method manually? That is, given an interface like so: IFoo = interface procedure Foo1; procedure Foo2; ... procedure FooN; end; Is anything similar to the following supported? IFooHelper = interface helper for IFoo procedure Bar; end; or IFooBar = interface(IFoo) procedure Bar; end; TFooBar = interface(TInterfacedObject, IFoo, IFooBar) private FFoo: IFoo; public procedure Bar; property Foo: IFoo implements IFoo; end; I'm specifically wondering about ways to that allow me to always refer to IFoo, IFooBar, or TFooBar, without switching between them, and without adding all of IFoo's methods to TFooBar.

  • Show extra info for Preference screens when CheckboxPreference summary field is not enough long?

    - by Pentium10
    I have situation when you can enabled/disable modules for my Android application. For this I use a CheckboxPreference screen. This is all good, but the summary field gets cut off if longer descriptions are added than 2 lines. Suppose I have 4-5 lines of description available for each module, I would like to display this in a helper window. I tried to bind a click event to the CheckboxPreference, but that fires for the whole line, so not only when the checkbox is clicked, and more, where ever you click on the line the checkbox is toggled. So now I am wondering if this can be fixed. So if the user needs more info, just taps the text and the helper opens up, and if want to toggle the settings it taps the checkbox. How would you do it? I am open to other ideas too, if they do work.

  • Activation Function, Initializer function, etc, effects on neural networks for face detection

    - by harry
    There's various activation functions: sigmoid, tanh, etc. And there's also a few initializer functions: Nguyen and Widrow, random, normalized, constant, zero, etc. So do these have much effect on the outcome of a neural network specialising in face detection? Right now I'm using the Tanh activation function and just randomising all the weights from -0.5 to 0.5. I have no idea if this is the best approach though, and with 4 hours to train the network each time, I'd rather ask on here than experiment!

  • Rails - default value in text_field but only for new_record?

    - by jyoseph
    On a Content model have an attribute named slug. When creating a new record, I want to use a helper to populate this field, but on an existing record I want to use the value from the database. Currently I have: <%- if @content.new_record? -%> <%= f.text_field :slug, :value => "#{generate_slug(6)}" %> <%- else %> <%= f.text_field :slug %> <%- end %> But that seems a bit verbose. Is this the best way, or is there no other way? (Rails newb just trying to find the "Rails way" on issues I'm unsure of) Edit I should note that the helper is currently in /app/helpers/application_helper.rb

  • CakePHP - radio button not showing error message

    - by teepusink
    Hi, I'm unable to get the error message to show up when creating a radio form using the CakePHP form helper. This is what I have now. $options=array('active'=>'Active','inactive'=>'Inactive'); echo $form->input('Status', array( 'type' => 'radio', 'id' => 'EntryStatus', 'name' => 'data[Entry][status]', 'options' => $options )); What am I missing? I'm using CakePHP 1.2.7 and this is what I have in the validation 'status' = array( 'notempty' = array( 'rule' = 'notempty', 'required' = true, 'message' = 'yo' ) ) Tried the answer from http://stackoverflow.com/questions/1388823/form-helper-for-creating-radio-button-in-cakephp and it's giving me a select option form instead. Thanks, Tee

  • What are All the Ways a Programmer Could use PHP to Send an Email?

    - by Alan Storm
    I'm looking for a list of built in PHP functions that a programmer could use to send an email. The obvious answer here is mail(), but I'm also looking for a list of functions someone might use to manually open a connection to an MTA, or spawn a process on the local machine which might in turn send an email using sendmail, postfix, etc. The context here is I want to scan a large, unknown codebase for code that's sending out email (because we already located a call to mail(), and that's not doing it)

  • ZendX jQuery Autocomplete not working in framework

    - by Jan-Dean Fajardo
    I added the ZendX library. Added the helper in controller: public function init() { $this->view->addHelperPath( 'ZendX/JQuery/View/Helper' ,'ZendX_JQuery_View_Helper'); } Created a form for view page: public function indexAction() { // Filter form $this->view->autocompleteElement = new ZendX_JQuery_Form_Element_AutoComplete('txtLocation'); $this->view->autocompleteElement->setAttrib('placeholder', 'Search Location'); $this->view->autocompleteElement->setJQueryParam('data', array('Manila', 'Pasay', 'Mandaluyong', 'Pasig', 'Marikina','Makati')); } Load jQuery and form in view page. <?php echo $this->jQuery(); ?> <form> <?php echo $this->autocompleteElement; ?> </form> The form is visible in the view page. But the autocomplete isn't working. I even don't see any jQuery script in the source page. Have I missed something?

  • Mac OSX: Passing a link to file from user process to kernel module.

    - by Inso Reiges
    Hello, I need to pass a link to file from a user process to the OSX kernel driver. By link i mean anything that uniquely identifies a file on the local filesystem. I need that link to do I/O on that file in kernel. The most obvious solution seems to pass a file name and use a VFS vnode lookup. However i noticed, that Apple Disk Images helper process passes a raw data array for image-path property to driver when attaching a disk image file: <2f 56 6f 6c 75 6d 65 73 2f 73 74 6f 72 61 67 65 2f 74 65 73 74 32 2e 64 6d 67> What is that diskimages-helper passes to the kernel driver? Some serialized type perhaps? If yes, what type is it and how can i use it?

    Hi Business logic is coded in pl/sql paackages procedures and functions. Java programs call pl/sql packages procedures and functions to do database work. Issue now is pl/sql programs store excpetions into Oracle tables whenever a execption is raised. How would my java programs get the execptions since the exception instead of being propogated from pl/sql to java is getting persisted to a oracle table.
