The com_auto Administration using barcode creation for .net framework control to generate, create pdf417 2d barcode image in .net framework applications. Bar Code Scanner Environments The pure display .net vs 2010 pdf417 2d barcode of data on the website was relatively simple; administration of the data, by its nature, is a little more complicated. As administrator, you have to be able to display, modify, insert, delete, and publish data.

This involves significantly more interactivity than there was in the simple listing on the website.. The Component Table Joomla!, by the barcode pdf417 for .NET way, administers all menu items of the component in the [prefix]components table. The menu items of all of the components in the administration area have to be recorded here as well.

The com_auto component was also entered there: A graphic that is to be displayed next to the menu is also recorded there ("js/ThemeOffice/component.png"). You will find the graphics in the [pathto-Joomla]/includes/js/ThemeOffice folder.

You need several files to be able to create the administration component. You will find the following files in the [pathtoJoomla]/administration/components/ com_auto/ folder:. /administration/components/ /administration/components/controller.

Experts on entry barcode pdf417 for .NET points will notice that this looks very familiar. Everything is familiar except for the if query, which searches for additional controllers.

. Controller (/adm inistration/components/controller.php). The basic contro PDF 417 for .NET ller looks familiar to us as well:. /administration/ components/controller.php:. < php jimport barcode pdf417 for .NET ("joomla.application.

Now we see some differences. We have an additional controller and it has quite a bit of code. /administration/ components/controllers/auto.php:. < php defined PDF417 for .NET ("_JEXEC") or die(); class AutosControllerAuto extends AutosController { function __construct(){ parent::__construct(); [ 282 ]. 15 $this->re gisterTask( "add", "edit" ); $this->registerTask( "unpublish", "publish"); } function edit() { JRequest::setVar( "view", "auto" ); JRequest::setVar( "layout", "form" ); JRequest::setVar("hidemainmenu", 1); parent::display(); } function save() { $model = $this->getModel("auto"); if ($model->store($post)) { $msg = JText::_( "Auto Saved!" ); } else { $msg = JText::_( "Error Saving Auto" ); } $link = "index.php option=com_auto"; $this->setRedirect($link, $msg); } function remove(){ $model = $this->getModel("auto"); if(!$model->delete()) { $msg = JText::_( "Error: One or more Autos could not be Deleted" ); } else { $msg = JText::_( "Auto(s) Deleted" ); } $this->setRedirect( "index.php option=com_auto", $msg ); } function publish(){ $this->setRedirect( "index.

This controller implements the edit, save, remove, publish, and cancel methods. The model is instantiated within these methods and when required, the store method, for example, is called in the model. Messages about success or failure are output by means of the JText and JError static classes:.
