The XmlDocument class stores the name of the document being processed in its BaseURI property. Although the BaseURI property is a string, it stores the file name as a URI. As a result, a file name such as c:\data.xml is stored in the BaseURI property as file:///c:/data.xml. Note that in the .NET Framework, URIs are rendered through an ad hoc type the Uri class. To obtain the local path from a URI, you must first create a new Uri object and query its LocalPath property, as shown here: Uri u = new Uri(BaseURI); string filename = u.LocalPath; Why can't we just use the file name in the URI form To avoid the rather boring task of parsing the path string to extract the directory information, I use the FileInfo class and its handy DirectoryName property. Unfortunately, however, the FileInfo class can't handle file names in the URI format. The following code will throw an exception if filename is a URI: FileInfo fi = new FileInfo(filename); m_watcher.Path = fi.DirectoryName; m_watcher.Filter = fi.Name; To finalize the watcher setup, you also need to define the change events that will be detected and register a proper event handler for each of them. You set the NotifyFilter property with any bitwise combination of flags defined in the NotifyFilters enumeration. In particular, you can choose values to detect changes in the size, attributes, name, contents, date, and security settings of each watched file. The following code simply configures the watcher to control whether the monitored file has something new written to it. The LastWrite flag actually causes an event to fire whenever the timestamp of the 197 vb.net pdfreader: How to Read PDF document in Vb . net ????? - MSDN - Microsoft visual basic read pdf Adobe PDF Reader Control | Adobe Community - Adobe Forums

They had to decide who would do what work, how to call each service, and what format the response would come in After deciding which team would deliver each component, they then had to integrate their schedules and plan for enough time for each team to complete integration testing The MSN client team was able to work on the UI for parental controls but could not actually write all the code to integrate or test until the Passport team had made significant progress In terms of testing, this was a major challenge because the test team had to ensure that they were using the right build of the client for the right version of the services when testing Of these two scenarios, loosely coupled clearly provides more flexibility and self-determination for both services Even in Microsoft, tightly coupled, co-development scenarios are hard to manage.

Doing a project like this with multiple companies over the Internet is even more challenging Many of our sites integrate with external companies One example is credit card processing We take credit cards that are processed through services on the Internet, we also take PayPal for payment, and we might integrate with many retailers' extranet Web services The loosely coupled projects, the ones that have well-defined interfaces, shipped on time The very tightly coupled projects often bogged down and seemed as if they would never ship Every one of these non-Microsoft organizations is continuing to evolve their service in parallel with our own development efforts Tightly coupled services have a hard time testing without a current instance of the platform service A loosely coupled service can often stub out calls to other services or use emulators (See the section titled "Integration Testing vs. IL_004f: call [mscorlib]System.Int32::ToString() IL_0054: IL_0055: IL_0056: IL_0057: IL_0058: IL_005d: IL_005e: IL_005f: stelem.ref nop ldloc.2 ldc.i4.5 ldstr stelem.ref nop ldloc.2 "\r\n" [System.Windows.Forms]System.Windows.Forms.TextBox::set_Text(string ) IL_006a: nop //000132: ' For the output to show up. //000133: edtOutput.Update() IL_006b: IL_006c: ldarg.0 callvirt instance class ShowBPs.ShowBPsForm::get_edtOutput() IL_0071: callvirt instance void [System.Windows.Forms]System.Windows.Forms.TextBox Using the XmlHotDocument Class To take advantage of the new class in a client application, start by declaring and instantiating a variable of that type, as follows: XmlHotDocument m_hotDocument = new XmlHotDocument(); Next you register an event handler for the UnderlyingDocumentChanged event and call the Load method to build the XML DOM. When you think you are ready to start 198 Test Flags and Emulation" later in this chapter) This allows testing to continue without an instance of the other service Integration testing is still done, but the testing of the core functionality of the service is not blocked..

Registering a handler for the custom UnderlyingDocumentChanged event is not mandatory, but doing so gives your application an immediate notification about what happened. The value of the HasChanges property automatically indicates any underlying changes that the current XML DOM does not yet reflect, however. When you build an XML DOM, the HasChanges property is reset to false. Figure 5-6 shows the sample application immediately after startup.

The less state a service has to maintain, the more failures it can experience with any component while continuing to provide a good user experience. An example of this in software might be Outlook sending an e-mail message. If the message fails to go out on the first try, Outlook tries again later. The user rarely notices. When a service takes a long time to complete a transaction and needs to store unique user or businesscritical data, it is considered to be more stateful and thus less resilient to failure. Compare stateful to working on a Microsoft Word document for hours, and then experiencing a crash just as you are trying to save the file. It might be a single crash, but the impact on the user is dramatic. ldc.i4.1 add.ovf stloc.0 ldloc.0 ldc.i4.5 ble.s End Sub nop ret IL_0013 vb.net open pdf file in adobe reader Read & Parse a PDF file using VB .
