Because you most often want to display the price with a dollar sign in front, you have to strip out that sign when displaying the price in the box. The next step is making sure that saving these objects works too. To do this, you need to change the create and update methods. First of all, though, you need a small helper method in the controller that allows you to handle price more easily. So, in the end of the class, add this method declaration: private def intern_price if params[:product] && params[:product][:price] v = params[:product][:price].split('.').map(&:to_i) params[:product][:price] = v[0]*100 + v[1] end end This helper would reformat the price into cents if a price parameter was submitted. The private in the beginning says that this method should not be available as an action on the controller. Next you need to change the create method to handle the new price: def create intern_price @product = Product.new(params[:product]) if @product.save flash[:notice] = 'Product was successfully created.' redirect_to :action => 'list' else @product_types = ProductType.find(:all) @product_categories = ProductCategory.find(:all) render :action => 'new' end end The other thing you added was @product_types and @product_categories, in case something goes wrong. This lets you see the original page again, with error messages attached. You need to do the same thing with the update method: def update @product = Product.find(params[:id]) intern_price if @product.update_attributes(params[:product]) flash[:notice] = 'Product was successfully updated.' redirect_to :action => 'show', :id => @product else @product_types = ProductType.find(:all) @product_categories = ProductCategory.find(:all) render :action => 'edit' end end .net ean 13 reader .

C# . NET EAN - 13 recognition reader control component is used to scan & read EAN - 13 barcode from image in C#. NET class applications. We will discuss managedQuery() and its sibling query() later in this section and also in 3. For now, realize that a query in Android returns tabular data. The projection parameter allows you to define the columns you are interested in. You can also reduce the overall result set and sort the result set using a SQL order-by clause (such as asc or desc). Also note that an Android query must return a column named _ID to support retrieving an individual record. Moreover, you must know the type of data returned by the content provider whether a column contains a string, int, binary, or the like. After the query is executed, the returned cursor is passed to the constructor of SimpleCursorAdapter, which adapts records in the dataset to items in the user interface (ListView). Look closely at the parameters passed to the constructor of SimpleCursorAdapter: SimpleCursorAdapter adapter = new SimpleCursorAdapter(this, R.layout.noteslist_item, cursor, new String[] { Notes.TITLE }, new int[] { android.R.id.text1 }); Let s start by creating a new project in JBoss Tools: 1. Select File New JSF Project. 2. For Project Name, enter richfaces-echo. 3. For JSF Environment, select JSF 1.2, Facelets, RichFaces. 4. For Template, select one based on the Tomcat version you are using. 5. Click Finish to create the project. We ll change it a bit: <h1>Products</h1> <table width="400"> <tr> <th align="left">Name</th> <th>Type</th> <th>Price</th> <th> </th> <th> </th> </tr> <% for product in @products %> <tr> <td align="left" valign="top"><%= link_to h(productname), {:action => 'show', :id => product}, :class=>'productLink' %></td> <td align="right" valign="top"><%=h productproduct_typename%></td> <td align="right" valign="top"><%=price product %></td> <td> </td> <td><%= link_to 'Remove', {:action => 'destroy', :id => product}, :confirm => 'Are you sure ', :post => true %></td> </tr> <% end %> </table> <%= link_to 'Previous page', { :page => @product_pagescurrentprevious } if @product_pagescurrentprevious %> <%= link_to 'Next page', { :page => @product_pagescurrentnext } if @product_pagescurrentnext %> <br /> <%= link_to 'New product', :action => 'new' %> As you can see, you hard code the columns, and you only display the name, type, and price. Specifically, look at the second parameter: an identifier to the view that represents the items in the ListView As you ll see in 3, Android provides an auto-generated utility class that provides references to the resources in your project This utility class is called the R class because its name is Rjava When you compile your project, the AAPT generates the R class for you from the resources defined within your res folder For example, you could put all your string resources into the values folder and the AAPT will generate a public static identifier for each string Android supports this generically for all of your resources For example, in the constructor of SimpleCursorAdapter, the NotesList activity passes in the identifier of the view that displays an item from the notes list. .net ean 13 reader .
