Once you have initialized the user interface by creating a new GladeXML object, you can retrieve widgets with glade_xml_get_widget(). This function returns a widget that is already instantiated, which is referred to by the name you gave it in Glade. GtkWidget* glade_xml_get_widget (GladeXML *xml, const char *name); The widget returned by glade_xml_get_widget() is already set up with all of the properties that you set in Glade. You can use this widget like any other GtkWidget that was created in your application using the functions provided in GTK+. This shows one of the main advantages of Libglade you do not have to provide all of the monotonous code for setting up the user interface and can quickly get to developing more interesting aspects of the application. Another useful function is glade_xml_get_widget_prefix(), which allows you to retrieve a list of widgets that have the same prefix as the given string. If you name all of your widgets according to their type or what window they belong to, this function can be very helpful. GList* glade_xml_get_widget_prefix (GladeXML *xml, const char *name);

There are a number of rules of thumb one can infer from the basic idea that security by obscurity may not be sufficient for some systems For instance, system designers should not attempt to invent their own algorithms for encryption to ensure the confidentiality of information Such designers may believe that because they are designing their own algorithms, it will be too difficult for adversaries to reverse engineer them However, designing encryption algorithms is a challenging business that should be left to cryptographers Cryptographers are mathematicians who spend their living studying how to encode and decode information They are trained in number theory and other aspects of mathematics, and they spend their careers developing new encryption algorithms and attempting to break the algorithms of others.

The next step in getting your application ready for use is to connect the signal handlers that you created in Glade. In Listing 10-1, glade_xml_signal_autoconnect() was used to connect all of the signals at once. void glade_xml_signal_autoconnect (GladeXML *xml); To autoconnect signals, Libglade opens a NULL version of GModule, which will provide access to your application s symbol table. The function then tries to find functions with the same signal handler name, which means that the names in the Glade file must match those of the callback functions in your application. This function will work only if GModule is supported on the user s system. Another option for connecting signals is to use glade_xml_signal_autoconnect_full(). This function allows you to provide a callback function that will connect all of the signals for you. This way you can provide any necessary customization. void glade_xml_signal_connect_full (GladeXML *self, const gchar *handler_name, GladeXMLConnectFunc connect_func, gpointer data); Listing 10-2 presents a simple GladeXMLConnectFunc implementation that uses GModule in the same way as in glade_xml_signal_autoconnect(). This function is called for every signal in the Glade user interface file.

For all practical purposes, we need to worry about only two types of hosting environments:

Listing 10-2. Autoconnecting Signals static void connect_func (const gchar *callback_name, GObject *object, const gchar *signal_name, const gchar *signal_data, GObject *connect_object, gboolean connect_after, gpointer data) { static GModule *module_self = NULL; gpointer handler_func; module_self = g_module_open (NULL, 0); g_assert (module_self != NULL); if (g_module_symbol (module_self, callback_name, &handler_func)) { if (connect_object && connect_after) g_signal_connect_object (object, signal_name, handler_func, connect_object, G_CONNECT_AFTER); else if (connect_object && !connect_after) g_signal_connect_object (object, signal_name, handler_func, connect_object, G_CONNECT_SWAPPED); else if (!connect_object && connect_after) g_signal_connect_after (object, signal_name, handler_func, data); else g_signal_connect (object, signal_name, handler_func, data); } else g_warning ("The callback function could not be found: %s", callback_name); } You already know how to use GModule, so the code in Listing 10-2 should be understandable to you. However, there are two new functions used for connecting signals that were introduced in Listing 10-2, which I will explain now. When you connect a signal with g_signal_connect(), your callback function will be run before the standard callback function. This allows you to override the standard callback with your own in some cases. Alternatively, if you want your callback function to run after the default, you can connect the signal with g_signal_connect_after(). gulong g_signal_connect_after (gpointer object, const gchar *signal_name, GCallback handler, gpointer data); Another useful signal connection function is g_signal_connect_object(), but it temporarily increases the reference count to ensure that the GObject provided to the fourth parameter will

Deploying to an IIS 7 environment to support the routing features of ASP.NET MVC requires far less configuration than the older versions of IIS. Most of the configuration decisions for IIS 6 and older versions revolve around routing, where your deployment decision could affect how you configure your routes. To deploy an ASP.NET MVC application, you ll need to make sure IIS is installed on the target machine as well, as either .NET 3.5 with Service Pack 1 or .NET 4. Next, we ll see how to deploy to an IIS environment using XCOPY deployment.
