Overview of .Net XmlReader and XmlWriter Object

XmlReader

Can read XML data both from file or stream. Readonly access. Also, provides information about the XML data.

XmlTextReader class is derived from XmlReader. It provides faster access to XML data though it does not support
validating DTD or XML schema.

XmlValidatingReader class supports both DTD and schema validation.

Attributes of XmlTextWriter class are AttributeCount, Depth, HasAttributes, HasValue, IsEmptyElement, Item, Value. Some methods are: IsStartElement, MoveToElement, MoveToFirstAttribute, MoveToNextAttribute, Read, ReadAttributeValue, ReadString, ReadStartElement, ReadEndElement, Skip

Example

   

dim reader as New XmlTextReader("")
   while reader.Read()
	select case reader.Nodetype
		case XmlNodeType.Element
			Console.Write("<"+reader.name);
			While(reader.moveToNextAttribute())
				Console.Write(" "&reader.name & "='" & reader.value & "'")
   End While
   Console.Write(">")
   if reader.HasAttributes then
   while reader.movetonextAttribute()
	Console.Write(reader.value)
   End While
   end if

  case XmlNodeType.Text
	Console.Write(reader.value)		
  case XmlNodeType.EndElement
	Console.WriteLine("")
end select
end while

• Features you are required to understand: No-impact applications: isolate applications, remove DLL effects, Keeping the Components Private: components available only to the application, Controlled Code Sharing using GAC, Side by Side Versioning: Multiple versions of the same application, Xcopy Deployment: Without registry entries (copy to a directory), On the fly updates, Integrated with Microsoft Windows Installer, Enterprise Deployment: Use Active Directory to deploy applications on user login or computer start.
• Packaging: Assemblies (deploy the .dll and .exe files), Cabinet Files (.cab): Compress the .exe files into .cab files, Create .msi files
• Distribution: Xcopy or FTP: CLR applications with no registry entries, Code Download, Use windows installer
• Four types of deployment projects: Setup, Web-setup, Cab, Merge Module
• Creating different types of deployment projects: Visual Studio: File-> New project ->other project types-> set up and deployment -> then select Setup, Web Setup, Merge Module, or CAB project
• Structuring a .NET Application For Easy Deployment
• About Merge Module Projects: Installing and deploying components
• Implementing Versioning and Side-by-Side Deployment: Deploy assemblies with different version numbers in the global assembly.

Deploying .Net Windows Applications

• Ways to deployment: XCOPY, Automated setup application
• Use XCOPY only when there is no external dependencies other than .Net framework. And it is guaranteed that .Net framework is installed in all the target machines. Also, make sure the application directory contains all the files
• Command example: XCOPY d:myApplication c:deployedApplication /s — /s indicates subdirectories will also be copied
• Setup Applications: two types: setup projects and merge module projects
• Setup projects: installs your application to the target machine
• Merge module projects: Used to deploy controls and components. It can be merged with a setup project
• To create setup project: File Menu->Add Project -> New Project->setup project-> setup project creation wizard comes. Select options as appropriate. It will be mostly common sense.
• Merge module project: File Menu->Add Project -> New Project->setup and deployment project-> setup wizard. Select options as appropriate. It will be mostly common sense.
• Setup project is also displayed in the project explorer. Right click and select properties to provide build properties.

Brought from our old-site (yes, pretty old short-note): http://salearningschool.com/displayArticle.php?table=Articles&articleID=636&title=Debug%20and%20Trace%20Classes%20in%20.Net

Debug and Trace classes in .Net

You can always debug your applications line by line. However, when the applications get very bigger/larger, debugging line by line may not be an efficient way for finding errors in code (well, you can first find out the error region and then can debug line by line). Debug and Trace classes are handy in such cases. Using Debug and Trace classes, you can find errors and write them in a file or create an event log. Later, you can check the file or the event log to see what kinds of errors the applications are causing. They both provide the same functionalities except that Debug class works only in the debug mode. Trace can work even after the applications are released and also you can control the error reporting from released versions. In a .config file you can change the behavior of the Trace class.

Logging Trace Output into a text file

• 1. Create a FileStream object instance and map it to a file
• 2. Create a TextWriterTraceListener instance and make the text file as the targe of this listener
• 3. Add this listener to the Trace.Listeners collection
• 4. set Trace.AutoFlush to be true
• 5. where required you can use Trace.Write method to send error messages to the file
• 6. Trace.Write, Trace.WriteLine, Trace.WriteIf, Trace.WriteLineIf can be used to send error message to the file
• 7. Trace.Assert method writes error messages only if the supplied condition fails. Trace.Assert also displays the error in a MessageBox
• 8. Trace.Fail causes an Trace.Assert unconditionally

Logging Trace output into an Event Log

• 1. Create or open an Event Log
• 2. Set the Source property of Event Log
• 3. Create an instance of EventLogTraceWriter and specify the new event log as it’s target
• 4. Use Trace.AutoFlush[automatic sending], or Trace.Flush [send error messages explicitly]
• 5. Where required, you can use Trace.Write method to send error messages to the file
• 6. Trace.Write, Trace.WriteLine, Trace.WriteIf, Trace.WriteLineIf can be used to send error messages to the file
• 7. Trace.Assert method writes error messages only if the supplied condition fails. Trace.Assert also displays the errors in a MessageBox
• 8. Trace.Fail causes a Trace.Assert unconditionally

TraceSwitches

TraceSwitch/BooleanSwitch class can be used to control the error messaging that the Trace class generates.
