![]() ![]() The ProfileProvider class simplifies the interaction with the CookieHelper class by providing two methods: GetColor and SaveColor. The CookieHelper class (Figure 1) encapsulates these actions to allow you to more easily read, write, and delete cookies. Likewise, to delete a cookie, subtract a year from its expiration date. In order to make a cookie persistent across different browser sessions, you need to specify the cookie's expiration, such as: public static void WriteCookie(HttpCookie cookie)Ĭookie.Expires = (31) CookieHelper.cs simplifies the process of storing and retrieving values from a cookie.ProfileProvider.cs defines a custom class that reads and writes the color value to the user's profile (in this case, a cookie).DisplayWebSlice.ascx renders the Web Slice content by reading the cookie and setting the background color.DisplayPage.aspx is the alternative display source for the Web Slice.WebSlice.ascx represents the drop-down control used to select a color.Default.aspx is the page loaded by the browser.Although this demo has been built by using ASP.NET 3.5, you can adapt this concept to any other Web technology or language. This allows us to render different content in the Web Slice preview window. The Web Slice in this demo uses an alternative display view. For more information, please refer to ASP.NET Cookies Overview overview. In this sample we use cookies to store the user profile in the Web site and later retrieve the same information from within the Web Slice. You can use cookies to store non-sensitive information, user preferences, Web Slice settings, and so on. Visual Studio Web Developer 2008 Express EditionĭEMO 1 - Using cookies to store user profileĬookie-based authentication is broadly supported and works regardless of the security settings of the Web Slice.In order to run and build the samples, you will need to install one or more of the following: You will find three different demos attached to this article, one for each of these scenarios. Web Slices in Internet Explorer 8 can authenticate to their Web site using any of the following: For example, a Web Slice could automatically supply a username and password in order to retrieve email from a Web server. Many scenarios require some sort of security layer to authenticate the user by remembering credentials across different browsing sessions, a Web Slice becomes more user-friendly. Web Slices can leverage some of the security features of a standard Web page or Really Simple Syndication (RSS) feed. DEMO 3 - Using HTTPS+Digest on IIS to secure the Web Slice.DEMO 2 - Using cookies to store user credentials (ASP.NET Membership).DEMO 1 - Using cookies to store user profile.This topic contains the following sections: This topic covers the security model of Web Slices and includes samples of authenticated scenarios in ASP.NET. To learn how to create Web Slices, refer to Subscribing to Content with Web Slices. Ideal for graphical menus of equal size.Web Slices allow you to subscribe to parts of a Web page and view updates directly from the Internet Explorer Favorites bar. Simply select the slice you need duplicating, click the duplicate slice tool and then tell Web Slicer where you want the new slice created, above, below, to the left or to the right. The duplicate slice tool allows you to quickly create repeating slices. Select multiple slices and align them to ensure they are lined up on your design. ![]() Need to divide an image into equal pieces? No problem, simply tell Web Slicer how many rows and columns you want and all the required slices are created instantly. Preview the output of the slice without the need to export first. Select between Jpeg, GIF or PNG formats and specify the level of compression and number of colours for Jpeg and GIF respectively. Web Slicer can open all the main image formats, jpeg, PNG, BMP (Bitmap), Tif and also Photoshop PSD files saved from either Photoshop Elements or Photoshop CS.Įach slice can be configured with itÃ?¯Ã?¿Ã?½s own export settings quickly and easily. ![]() Rather than defining slices across the entire layout like other web slicing tools do, Web Slicer allows you to define individual rectangular areas for exporting. You can even load a slice layout into multiple images and export the same slices. With Web Slicer you can easily take your Web site templates (Photoshop Elements/CS PSD, Jpeg, Tif, Bitmap, Png) and slice them up ready to be built into your new Web site. ![]()
