Convert Excel file to PDF from C# / VB.NET applications - GemBox
Convert Excel files between various spreadsheet formats and to PDF, XPS or image format with GemBox.Spreadsheet in C# and VB.NET.

This function is similar to what you saw earlier in that it creates an instance of the proxy to the Flash-db.com web service and an instance of the object type that contains the results to the doCompanyInfo() web method call. It then generates HTML for a table using a StringBuilder and places this HTML into the Text property of the Label control. Obviously, populating a Label control is not the most ideal way to represent some data on the screen, but it suffices just fine for the purposes of this sample. In such scenarios, it s best to bind a typed data structure to one of the more sophisticated ASP.NET data-bound controls, such as GridView or DataList. The proxy to the Flash-db.com web service is called CompanyInfoService. An instance of this proxy is first created, called svc. This exposes an object of type CompanyInfoResult, which is used to store the returned information from the service. The second line creates an instance of this type, called rslt, into which the results of a doCompanyInfo web method call are loaded. This web method takes three parameters; the first two are username and password. The web service is open, so you can put anything in for the username and password parameters. The third parameter is the ticker for which you are seeking the company information. The company name (result.company) is then appended to a string containing text (Current Price:), which in turn is appended to the last traded price for the stock (result.lastPrice). You can see this in Figure 10-8.

Listing 11-16. Test the MyIPAddress Widget (ipaddresstest.c) #include <gtk/gtk.h> #include "myipaddress.h" static void ip_address_changed (MyIPAddress*); int main (int argc, char *argv[]) { GtkWidget *window, *ipaddress; gint address[4] = { 1, 20, 35, 255 }; gtk_init (&argc, &argv); window = gtk_window_new (GTK_WINDOW_TOPLEVEL); gtk_window_set_title (GTK_WINDOW (window), "MyIPAddress"); gtk_container_set_border_width (GTK_CONTAINER (window), 10); g_signal_connect (G_OBJECT (window), "destroy", G_CALLBACK (gtk_main_quit), NULL); ipaddress = my_ip_address_new (); my_ip_address_set_address (MY_IP_ADDRESS (ipaddress), address); g_signal_connect (G_OBJECT (ipaddress), "ip-changed", G_CALLBACK (ip_address_changed), NULL); gtk_container_add (GTK_CONTAINER (window), ipaddress); gtk_widget_show_all (window); gtk_main (); return 0; } /* When the IP address is changed, print the new value to the screen. */ static void ip_address_changed (MyIPAddress *ipaddress) { gchar *address = my_ip_address_get_address (ipaddress); g_print ("%s\n", address); g_free (address); }

This MyIPAddress widget is a very simple example of creating a new widget. For use in an actual application, it would have to be expanded greatly. For example, you would want to customize the pop-up menu that is displayed when the user right-clicks the widget. Another enhancement would be to allow the programmer to define custom IP address formats. You may want to try expanding the MyIPAddress widget before continuing on to the next section so that you can better understand what was covered in this section.
