These first-level nodes indicate the tables in the DataSet object. The children of each table denote the schema of the DataTable object. (See 3 for more information about XML schemas.) The schema can be slightly more complex if relations exist between two or more pairs of tables. The msdata namespace contains ad hoc attributes that are used to annotate the schema with ADO.NET-specific information, mostly about indexes, table relationships, and constraints. In-Line Schemas and Validation 3 hinted at why the XmlValidatingReader class is paradoxically unable to validate the XML code that WriteXml generates for a DataSet object with an in-line schema, as shown here: <DataSetName> <schema>...</schema> <Table1>...</Table1> <Table2>...</Table2> <DataSetName> In the final XML layout, schema information is placed at the same level as the table nodes, but includes information about the common root (DataSetName, in the 330 itextsharp read pdf fields vb.net: VB .

When enumerating a solution's projects, you're given the generic Project object. Your best route is to use the Kind property to retrieve the GUID that will help you determine the type of the project. Table 9-1 lists the project kind GUID strings. If you're working on a C++ project, immediately use the Object property to convert the Project into a VCProject, and then branch off to deal with that VCProject because few of the Project methods will work. VSProject objects are a little more forgiving about being accessed through the generic Project object.

The best way to find out how customers use your software is to watch them. When you have only a few users, and know when they will be using your software, and if they agree to let you watch them, this is a great solution. Knowing how the customers use your software goes beyond what can be discovered by a usability study. Knowing how the customers use your software means that you know how they learn to use the program, which tasks they perform most often, and which tasks they never use. When you install certain Microsoft applications, the dialog box shown in Figure 13-2 opens asking if you would like to help make the application better by providing feedback on your use of the product. If interested, you can enroll in the Customer Experience Improvement Program (CEIP). When you opt in to this program, anonymous data about how you use the application is occasionally uploaded to Microsoft when your computer is idle. At Microsoft, we know that to make great products, we need to understand as much as we can about how the products are used. Millions of people use Microsoft products, so it is impossible for us to contact even a fraction of the customer base for some of our itextsharp read pdf fields vb.net NET PDF Text Extractor & Converter - Extract Text from PDF C#/ VB ...

Because the validating parser is a forward-only reader, it can match the schema only for nodes placed after the schema block. The idea is that the parser first reads the schema and then checks the compliance of the remainder of the tree with the just-read information, as shown in Figure 9-2. An alternative method of determining the project type is to use the ProjectCodeModel property, which describes the code elements present in the project files I'll be discussing the code elements more in a moment The CodeModel object contains a Language property that returns a GUID string identifying the language This is the technique I used to determine the project type in the SettingsMaster add-in because I needed to work with all language types Note that the documentation is wrong in saying the language strings returned by the Language property are vsCMLanguage constants that constant doesn't exist The real constant is CodeModelLanguageConstants Code Elements One of the most amazing aspects of Visual Studio NET is that all the programming constructs for source files can be accessed easily through the object model. The fact we can now simply add, change, or remove items such as methods in all languages supported by Visual Studio NET without having to do the parsing ourselves opens up huge opportunities for all sorts of unique tools that might never have been created because parsing is so hard Every time I use the code elements to manipulate the code in a file, I'm amazed at how cool this capability really is To show you how easy it is to access and utilize the code elements, I created a macro, shown in Listing 9-1, that dumps the code elements out of the active document What's not obvious is that the code works for any language The output reports the name of the code element along with its code element type You can find this macro with this book's sample code in Macros\SimpleMacrosVB along with its supporting file, Utilities. Figure 9-2: How the .NET Framework validating reader parses a serialized DataSet object with an in-line schema. Due to the structure of the XML document being generated, what comes after the schema does not match the schema! Figure 9-3 shows that the validating parser we built in 3 around the XmlValidatingReader class does not recognize (I'd say, by design) a serialized DataSet object when an in-line schema is incorporated. larger products. CEIP data provides a massive amount of information that helps us understand how customers use our products I like to think of CEIP as being just like one of those Nielsen Ratings boxes used for collecting TV ratings, except for software. VB The following output shows a partial listing of the results returned from calling this macro on the SETTINGSMASTERVB file from the SettingsMaster project: SettingsMasterSettingsMaster(vsCMElementClass) SettingsMasterSettingsMasterRegSettings(vsCMElementVariable) SettingsMasterSettingsMasterm_ApplicationObject(vsCMElementVariab le) SettingsMasterSettingsMasterNew(vsCMElementFunction) ApplicationObject(vsCMElementParameter) 367. AddInInstance(vsCMElementParameter) One issue that's a little problematic when you're dealing with the code elements is consistency in how child items for an element are retrieved. For example, a CodeClass object uses the Members property to retrieve the subelements for the class when the class is a Visual Basic .NET or C# class. However, when the class is a C++ class described by the CodeClass object, the Children property retrieves the subelements. Toward the end of the DumpElements function, I use some nested Try Catch blocks to find the appropriate child elements. As you can see, CodeFunction objects use yet another property, Parameters, to get child objects. What's important is that you know there are possibly more ways than one to get child elements. Listing 9-1: DumpActiveDocCodeElements ' Dumps all the code elements for the open document of a project. Public Sub DumpActiveDocCodeElements() ' Where the output goes. Note that the OutputPane class comes ' from the Utilities macro project. Dim ow Elements") As OutputPane = New OutputPane("Open Doc Code Figure 9-3: The validating parser built in 3 does not validate an XML DataSet object with an in-line schema. Is there a way to serialize the DataSet object so that its XML representation remains parsable when an in-line schema is included The workaround is fairly simple. 331 Figure 13-2: CEIP option in Windows Live Messenger When a customer agrees to participate in the program, we collect anonymous, nontraceable data points detailing how the software is used, what hardware the software is installed on, and a variety of other bits of information to aid in understanding customer usage (confidential or personally identifiable data is never collected) The initial consumers of this data are often designers or user experience engineers The data, collected from millions of customers, provides a unique insight into how they use our products. ' Clear the output pane. ow.Clear() ' See if there's a document open. Dim Doc As Document = DTE.ActiveDocument If (Doc Is Nothing) Then ow.WriteLine("No open document") Exit Sub End If ' Get the code model for the doc. You have to get the project ' item to diddle down to the code elements Dim FileMod As FileCodeModel = Doc.ProjectItem.FileCodeModel If (Not (FileMod Is Nothing)) Then DumpElements(ow, FileMod.CodeElements, 0) Else ow.WriteLine("Unable to get the FileCodeModel!") End If End Sub Private Sub DumpElements(ByVal ow As OutputPane, _ ByVal Elems As CodeElements, _ ByVal Level As Integer) 368 Serializing to Valid XML As you can see in Figure 9-2, the rub lies in the fact that the in-line schema is written in the middle of the document it is called to describe. This fact, in addition to the forwardonly nature of the parser, irreversibly alters the parser's perception of what the real document schema is. The solution is simple: move the schema out of the DataSet XML serialization output, and group both nodes under a new common root, as shown here: <Wrapper> <xs:schema> ... </xs:schema> <DataSet> </DataSet> </Wrapper> Here's a code snippet that shows how to implement this solution: XmlTextWriter writer = new XmlTextWriter(file); writer.Formatting = Formatting.Indented; writer.WriteStartElement("Wrapper"); ds.WriteXmlSchema(writer); ds.WriteXml(writer); writer.WriteEndElement(); writer.Close(); If you don't use an XML writer, the WriteXmlSchema method would write the XML declaration in the middle of the document, thus making the document wholly unparsable. You can also mark this workaround with your own credentials using a custom namespace, as shown here: writer.WriteStartElement("de", "Wrapper", "dinoe-xml-07356-18011"); Figure 9-4 shows the new document displayed in Microsoft Internet Explorer. Dim Elem As CodeElement For Each Elem In Elems Dim i As Integer = 0 While (i < Level) ow.OutPane.OutputString(" i = i + 1 End While ' If there's an exception accessing the FullName property, ' it's probably an unnamed parameter. Dim sName As String Try sName = Elem.FullName Catch e As System.Exception sName = "'Empty Name'" End Try ow.WriteLine(sName + "(" + Elem.Kind.ToString() + ")") ' This is kinda weird. Some CodeElements use a Children property ' again, ' functions use the Parameters property. Dim SubCodeElems As CodeElements = Nothing Try SubCodeElems = Elem.Children Catch Try SubCodeElems = Elem.Members Catch If (TypeOf Elem Is CodeFunction) Then SubCodeElems = Elem.Parameters Else SubCodeElems = Nothing End If End Try End Try to get sub elements while others use Members.
