Recall that the Add Web Reference dialog box allows you not only to obtain a list of all XML web services located on your current development machine (as well as a well-known URL), but also to submit queries to UDDI servers. Basically, you have the following options: Browse for a UDDI server on your company intranet. Browse the Microsoft-sponsored UDDI production server. Browse the Microsoft-sponsored UDDI test server. Assume that you are building an application that needs to discover the current weather forecast on a per zip code basis. Your first step would be to query a UDDI catalog with the following question: Do you know of any web services that pertain to weather data If it is the case that the UDDI server has a list of weather-aware web services, you are returned a list of all registered URLs that export the functionality of your query. Referencing this list, you are able to pick the specific web service you wish to communicate with and eventually obtain the WSDL document that describes the functionality of the weather-centric functionality. As a quick example, create a brand-new console application project and activate the Add Web Reference dialog box. Next, select the Test Microsoft UDDI Directory link, which will bring you to the Microsoft UDDI test server. At this point, enter weather as a search criterion. Once the UDDI catalog has been queried, you will receive a list of all relevant XML web services. When you find an XML web service you are interested in programming against, add a reference to your current project. As you would expect, the raw WSDL will be parsed by the tool to provide you with a VB 2005 proxy.

How to extract text from an image using JavaScript - LogRocket Blog

Here s the XAML for the splash screen shown in Figure 6-4. It includes a Grid with a TextBlock and two Rectangle elements. (Rectangle is a shape-drawing element you ll learn about in 8.) The first rectangle paints the background of the progress bar, and the second paints the foreground. The two Rectangle objects are placed together in a single-celled grid so that one rectangle is superimposed over the other: <Grid xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"> <StackPanel VerticalAlignment="Center"> <Grid> <Rectangle x:Name="progressBarBackground" Fill="White" Stroke="Black" StrokeThickness="1" Height="30" Width="200"></Rectangle> <Rectangle x:Name="progressBar" Fill="Yellow" Height="28" Width="0"> </Rectangle> </Grid> <TextBlock x:Name="progressText" HorizontalAlignment="Center" Text="0% downloaded ..."></TextBlock> </StackPanel> </Grid> Next, you need to add a JavaScript function to your HTML entry page or ASP.NET test page. (If you plan to use both, place the JavaScript function in a separate file and then link to it in both files, using the source attribute of the script block.) The JavaScript code can look up named elements on the page using the sender.findName() method and manipulate their properties. It can also determine the current progress using the eventArgs.progress property. In this example, the event-handling code updates the text and widens the progress bar based on the current progress percentage: <script type="text/javascript"> function onSourceDownloadProgressChanged(sender, eventArgs) { sender.findName("progressText").Text = Math.round((eventArgs.progress * 100)) + "% downloaded ...";

Given that the String type can be quite inefficient when used with reckless abandon, the .NET base class libraries provide the System.Text namespace. Within this (relatively small) namespace lives a class named StringBuilder. Like the System.String class, StringBuilder defines methods that allow you to replace or format segments and so forth. What is unique about the StringBuilder is that when you call members of the StringBuilder, you are directly modifying the object s internal character data, not obtaining a copy of the data in a modified format (and is thus more efficient). When you create an instance of the StringBuilder, you will supply the object s initial startup values via one of many constructors. 5 dives into the details of class constructors; however, if you are new to the topic, simply understand that constructors allow you to create an object with an initial state when you apply the New keyword. Consider the following usage of StringBuilder: Imports System.Text ' StringBuilder lives here!

fn:contains(s1, s2) fn:count(x) fn:data(a)

sender.findName("progressBar").Width = eventArgs.progress * sender.findName("progressBarBackground").Width; } </script>
