ASP.NET Web PDF Document Viewer/Editor Control Librarysvc file is the Service attribute that tells the web server which type it should use: <% @ServiceHost Debug="true" Service="StrangelightsServicesGreetingService" %> Finally, you must configure the service Since WCF offers a choice of protocols, you use the configuration file to tell it which one to use The configuration file in Listing 10-9 shows a configuration file that could be used to configure your service The service element defines two endpoints; these are the protocols that a client can use to talk to this service One of the endpoints is a standard web service HTTP binding, and the other is a metadata exchange binding; this allows the service to expose metadata about itself that will tell any potential client how it should talk to the service This is the endpoint you ll use when you create the client proxy Listing 10-9. barcode font for excel download, free barcode generator microsoft excel, create barcode in excel 2013 free, barcode checksum excel formula, how to make barcodes in excel, free barcode generator add-in for excel, how to make barcodes in excel 2010, barcode generator excel download, excel barcodes, microsoft excel barcode generator free,<head> <title>Ajax Dashboard</title> <script type="text/javascript" src="js/autocomplete.js"></script> <script type="text/javascript" src="js/dom-drag.js"></script> <script type="text/javascript" src="js/common.js"></script> <script type="text/javascript" src="js/weatherForecast.js"></script> <script type="text/javascript" src="js/stockQuote.js"></script> <script type="text/javascript" src="js/news.js"></script> <script type="text/javascript" src="js/search.js"></script> <script type="text/javascript" src="js/taconite/taconite-client.js"></script> <script type="text/javascript" src="js/taconite/taconite-parser.js"></script> <link type="text/css" rel="stylesheet" title="style" href="css/styles.css" > </link> </head> <body> <%@ include file="weather/weatherForecast.jsp" %> <%@ include file="stockQuote/stockQuote.jsp" %> <%@ include file="news/newsItems.jsp" %> <%@ include file="search/search.jsp" %> <script type="text/javascript" src="js/ajaxDashboard.js"></script> <div style="position:absolute;overflow:auto;display:none;background-color:white" id="popup"> </div> </body> </html> This JSP is for the most part a simple placeholder for the JSPs that make up each component. At the top of the file are the references to each component s individual JavaScript file. Splitting out the JavaScript in this way makes the files more manageable and easier to change. JavaScript functions that are common to all the components are placed in the common.js file. The taconite-client.js and taconite-parser.js files are specific to the Taconite framework being used to build this example. Each component has its own JSP, which is included in the body section of the main JSP . Breaking out the components into their own JSP files makes maintenance easier and also simplifies the process of adding or removing them to the main JSP file. Also within the body tag is a reference to a JavaScript file named ajaxDashboard.js. The absolutely positioned div tag with an id attribute value of popup is used for the search component s drop-down list, which you ll inspect in the Building a Better Autocomplete section. Figure A-8. Scoring the PC board Start by laying the straight-edge ruler along the column of holes where you want to cut the PCB. Take a sharp knife and run it along the straight edge of the entire width of the board. The knife will bump along from hole to hole. At first, don t use very much pressure. Keep running the knife along exactly the same path over and over until a groove develops. It usually takes about ten passes. Repeat the process on the bottom side of the board. Bracing your thumbs at the groove, as shown in Figure A-9, gently bend the board down on both sides with your fingers. It should snap with only a reasonable amount of force. If it doesn t snap, continue to cut at the grooves to make them a little deeper and try again. You ll be left with a small PCB that s just the right size for your project. The Configuration File for a WCF Service <configuration xmlns="http://schemasmicrosoftcom/NetConfiguration/v20"> <systemserviceModel> <services> <service name="StrangelightsServicesGreetingService" behaviorConfiguration="MyServiceTypeBehaviors"> <endpoint contract="StrangelightsServicesIGreetingService" binding="wsHttpBinding"/>. class base has one field, state, and the class sub has another called otherState. The example shows that both fields can be used by the sub derived class, because state is inherited from the base class. #light type Base = class val state: int new() = { state = 0 } end type Sub = class inherit Base val otherState: int new() = { otherState = 0 } end let myObject = new Sub() printfn "myObject.state = %i, myObject.otherState = %i" myObject.state myObject.otherState The results of this example, when compiled and executed, are as follows: myObject.state = 0, myObject.otherState = 0 For this to work properly, the base class must have a parameterless constructor, that is, a constructor that does not take any arguments. If the base class does not have a parameterless constructor, then it cannot be initialized implicitly when the derived class is instantiated. This doesn t mean you can t derive from it; it just means you need to explicitly call the base class s constructor. You do this using the inherit keyword again but this time within the constructor s initializer block. The following example shows how to derive from a class that has no parameterless constructor: #light type Base1 = class val state: int new(state) = { state = state } end type Sub1 = class inherit Base1 val otherState: int new(state) = { inherit Base1(state) ; otherState = 0 } end let myOtherObject = new Sub1(1)
