There are three classes in the Commons File Upload library that we use in the file upload portlet. PortletDiskFileUpload manages the interaction with the portlet s action request and parses the request into a list of FileItem classes. The FileItem class is an object that represents either an uploaded file or a form input parameter. The class has a method for checking whether its object is a file or a form field. There are also methods for writing a file to disk, determining the size and content type of a file, and getting the name and value of the input parameters. rdlc pdf 417 PDF417 Barcode Creating Library for RDLC Reports | Generate ...

To configure the Object Data Source control, you need to set its TypeName property to localhost.ECommerceService. Also, set its SelectMethod property to GetProducts(). At run time the Object Data Source control creates an instance of the class specified by the TypeName property and calls SelectMethod on it. The returned data is then supplied to the GridView. There is a hyperlink at the bottom of the web form that points to ShoppingCart.aspx. This way, the user can navigate to the shopping cart. Now go to the code-behind file of the web form and import the localhost namespace. Remember that localhost is the web reference name that you specified while creating the web service proxy. Each user should have a unique shopping cart ID. Though you can use any unique ID, it is best to use Globally Unique Identifiers (GUIDs) so you are sure that the cart has a unique value globally. The code that generates a GUID for a user is shown in Listing B-11. Listing B-11. Creating a Unique Shopping Cart Identifier protected void Page_Load(object sender, EventArgs e) { if (Session["cartid"] == null) { Session["cartid"]= Guid.NewGuid().ToString(); } } rdlc pdf 417 PDF - 417 Client Report RDLC Generator | Using free sample for PDF ...

Free trial package available to insert PDF - 417 barcode image into Client Report RDLC . The PortletDiskFileUpload class also handles the temporary storage of any uploaded files. Files that are smaller than a specified size (default is 10KB) are stored in memory, and larger files are stored on the hard drive in a temporary repository. The setSizeThreshold() method sets the cutoff size for memory storage. The default location for the repository is the value of the Java system property java.io.tmpdir, which is the path to a temporary directory. The setSizeMax() method provides the size past which a file is to be rejected to conserve storage space or to defeat attacks on the server. The parseRequest() method on the PortletDiskFileUpload class throws a FileUploadException if there are any problems uploading the file. Common problems are that an uploaded file exceeded the maximum file size allowed, there is a disk full error, or the request is not a multipart form submission. public void Handle_Click(Object obj, RoutedEventArgs e) { } rdlc pdf 417 How to add Barcode to Local Reports ( RDLC ) before report ...

In the Page_Load event, we check whether a session variable named cartid already exists. If not, we create a new GUID by using the NewGuid() method of the Guid class. The GUID is then stored in the cartid session variable. This variable is used further while calling various web methods. Whenever a user clicks the Add to Cart button, we should add that product to the user s shopping cart. This is done in the SelectedIndexChanged event handler, as shown in Listing B-12. Listing B-12. Adding a Product to the Shopping Cart protected void GridView1_SelectedIndexChanged(object sender, EventArgs e) { ECommerceService proxy = new ECommerceService(); proxy.AddItem(Session["cartid"].ToString(), Convert.ToInt32(GridView1.SelectedValue), 1); } The code creates an instance of the ECommerceService proxy class. Then the AddItem() method of the proxy class is called. The shopping cart identifier stored in the session is passed to the AddItem() method along with the product ID. Because we set the DataKeyNames property of the GridView to Id, the SelectedValue property returns the value of the Id column for the selected row. The quantity is passed as 1.
