windows home server 2011 key code often locked away in vaults or hardware devices where only a privileged few can access them. If you re a rank and file programmer developing a strongly named assembly and you don t have access to your company s private key which is exactly the situation that Microsoft developers find themselves in, how can you fully test the assembly if you can t install it in the GAC or use its version number to do stron.
Then you ll switch to Visual Studio. NET and experience rapid application development RAD, Internet style. Along the way, you ll be introduced to important Web Forms programming techniques such as code behind and dynamic control initialization. Before you begin, it s worth noting what software you need to run this chapter s sample programs. First and foremost, you need the. NET Framework. Second, you need . , res it in a Microsoft SQL Server database. You gain Web farm compatibility because you can point all your servers to a common back end machine the one that hosts the database. You also achieve robustness because session state is preserved no matter what even if IIS is restarted or the Web server is reboot ed. If SQL Server is clustered or otherwise configured to survive hard failures, windows server 2008 key code , you can reboot the da. windows home server 2011 key code, osing session state. As a final learning exercise, try modifying Congo. aspx to store the DataSet that it binds to the DataGrid in the application cache. As it stands now, a physical database access is performed every time Congo. aspx is requested. Assuming the contents of the database don t change very often, it would be far more efficient to query the database periodically, store the results in the appli.
Monitor. Enter o try a 3 finally Monitor. Exit o If you do this in multiple threads and you will otherwise you wouldn t be using a monitor in the first place, be sure to box the value type one time and use the resulting reference in calls to Enter and Exit in all threads. If the value type you re synchronizing access to is a field, declare a corresponding Object field and store the boxed reference there. . windows home server 2011 key code, hey re attached to is meaningless.

For an extra measure of security over unencrypted connections, add the following entry to your Web server s Machine. config file machineKey validation 3DES Henceforth, Microsoft Outlook 2010 , Microsoft Office 2010 , ASP.

The Active Server Pages Solution A third solution to the problem of processing input from HTML forms on Web servers, and the one that made Windows a popular platform for Web applications in the second half of the 1990s, is Active Serve. , like this MyComposite.

To demonstrate, the console application in . home server 2011 key code - es can be stored statically for example, in JPEG files on the server, or they can be generated at run time and even customized for each request. Returning dynamically generated images frees controls from the limitations of HTML and opens the door to a world of possibilities, from controls that render graphs and pie charts to controls that render maps, formatted reports, and virtually anything else you can . windows home server 2011 key code, he text typed by the user.

d it inherits from Control to render itself to a Web page. Implementing IPostBackDataHandler enables a control to update property values using data transmitted in postbacks and also to fire change events. Controls that fire change events persist property values in view state in order to detect changes in property values. Controls can force postbacks by rendering HTML elements that use client side scripts t.
