You are creating a document-level solution for Microsoft Office Word 2003 by using Visual Studio Tools for the Microsoft Office System (VSTO). A transformation file is used to convert the solution document to an HTML file. The path to the transformation file is stored in a variable named filename. The Uniform Resource Identifier (URI) is stored in a variable named uri. An optional alias is stored in a variable named alias. You need to ensure that the solution document uses the transformation file that the user provides. Which code segment should you use?

• A. this.Application.XMLNamespaces.Add ((string)filename, ref uri , ref alias, true);
• B. this.XMLSchemaReferences.Add (ref uri , ref alias, ref filename, true);
• C. this.XMLNodes.Add ((string)filename, "", ref missing);
• D. this.XMLSaveThroughXSLT = (string)filename;

You create an add-in for Microsoft Office Visio by using Visual Studio Tools for the Microsoft Office System (VSTO). You install the add-in in a secure environment where local assemblies are not granted the FullTrust permission. You need to ensure that the add-in acquires the FullTrust permission after installation. What should you do?

• A. Create an Installer class in the add-in assembly. Override the Install method so that the class copies the add-in assembly to the %WINDIR%/SYSTEM32 folder.
• B. Configure the File System Editor to copy the add-in assembly to the global assembly cache.
• C. Configure the Custom Actions Editor to copy the add-in assembly to the %WINDIR% folder.
• D. Create an Installer class in the add-in assembly. Override the Install method so that the class associates the assembly with the LocalIntranet code group.

You are creating an add-in for Microsoft Office Word by using Visual Studio Tools for the Microsoft Office System (VSTO).
You create the following objects in the add-in:
a DataSource object named ExpenseBindingSource
a TableAdaptor object named ExpenseTableAdapter
a DataSet object named ExpenseData
a CachedDataItem object named DI
The ExpenseData object contains a table named Expenses. The DI object contains a data island of the ExpenseData object.
You need to ensure that any changes in the content of the DI object are updated in the Expenses table.
Which code segment should you use?

• A. Dim schemaReader As System.IO.StringReader = _ New System.IO.StringReader(DI.Schema) Dim xmlReader As System.IO.StringReader = _ New System.IO.StringReader(DI.Xml) ExpenseData.ReadXmlSchema(schemaReader) ExpenseData.ReadXml(xmlReader) ... ExpenseBindingSource.Add(ExpenseData) ExpenseTableAdapter.Update(ExpenseData.Expense)
• B. Dim XMLR As XmlReader = _ XmlReader.Create("books.xml", settings) XMLR.ReadStartElement(DI.Schema) XMLR.ReadValueChunk(DI.Xml.ToCharArray(), 0, DI.Xml.Length) ExpenseData.ReadXmlSchema(XMLR.NamespaceURI) ExpenseData.ReadXml(XMLR.Value(0).ToString()) ... ExpenseBindingSource.Add(ExpenseData) ExpenseTableAdapter.Update(ExpenseData.Expense)
• C. Dim XMLR As XmlReader = _ XmlReader.Create("books.xml", settings) XMLR.ReadStartElement(DI.Schema) XMLR.ReadValueChunk(DI.Xml.ToCharArray(), 0, DI.Xml.Length) ExpenseData.ReadXmlSchema(XMLR.NamespaceURI) ExpenseData.ReadXml(XMLR.Value(0).ToString()) ... ExpenseBindingSource.EndEdit() ExpenseTableAdapter.Update(ExpenseData.Expense)
• D. Dim schemaReader As System.IO.StringReader = _ New System.IO.StringReader(DI.Schema) Dim xmlReader As System.IO.StringReader = _ New System.IO.StringReader(DI.Xml) ExpenseData.ReadXmlSchema(schemaReader) ExpenseData.ReadXml(xmlReader) ... ExpenseBindingSource.EndEdit() ExpenseTableAdapter.Update(ExpenseData.Expense)

You create an add-in for a Microsoft Office Outlook application by using Visual Studio Tools for the Microsoft Office System (VSTO). The add-in contains a reference to an Outlook folder in a variable named folder. You need to process only the e-mail messages within the folder. Which code segment should you use?

• A. foreach ( Outlook.MailItem item in folder.Items ) { if ( item.Class == Outlook.OlObjectClass.olMail ) { //Process mail } }
• B. foreach (object item in folder.Items ) { if ((item as Outlook.MailItem ).Class == Outlook.OlObjectClass.olMail ) { //Process mail } }
• C. foreach (object item in folder.Items ) { if (item is Outlook.MailItem ) { //Process mail } }
• D. foreach ( Outlook.MailItem item in folder.Items ) { //Process mail }
