You are creating a document-level solution for Microsoft Office Word 2003 by using Visual Studio Tools for the Microsoft Office System (VSTO). The document is customized to add a toolbar with custom functionality. You write the following lines of code in the Startup event of the ThisDocument class.
Dim toolbar As Office.CommandBar = Me.Application . _ CommandBars.Add (Name:=" MyToolBar ", _ Position:= Office.MsoBarPosition.msoBarTop , Temporary:=False)
Dim button As Office.CommandBarButton = _ CType ( too lbar.Controls.Add ( _ Type:= Office.MsoControlType.msoControlButton , _ Temporary:=False), Office.CommandBarButton )
Dim btnClick As _ Office._CommandBarButtonEvents_ClickEventHandler = _ AddressOf Me.button_Click
AddHandler button.Click , AddressOf Me.b utton_Click The event handler for the button does not execute every time CommandBarButton is clicked.
You need to ensure that the event handler executes every time CommandBarButton is clicked.
What should you do?

• A. Change the scope of the CommandBarButton button variable to a class-scoped variable.
• B. Set the OnAction property of the CommandBarButton button object to Click.
• C. Change the scope of the ._CommandBarButtonEvents_ClickEventHandler delegate btnClick variable to a class-scoped variable.
• D. Set the Enabled property of the CommandBarButton button object to True.

You are creating a document-level solution for Microsoft Office Word 2003 by using Visual Studio Tools for the Microsoft Office System (VSTO).
The solution must meet the following requirements: The solution must save the document.
The users who do not have Microsoft VSTO Runtime installed can open the document. You need to ensure that the solution meets the requirements.
Which code segment should you use?

• A. Me.ReloadAs ( Microsoft.Office.Core.MsoEncoding . _ msoEncodingAutoDetect ) Me.Save ()
• B. Me.RemoveTheme () Me.Save ()
• C. Me.RejectAllRevisionsShown () Me.Save ()
• D. Me.RemoveCustomization () Me.Save ()

You are creating a document-level solution for Microsoft Office Word 2003 by using Visual Studio Tools for the Microsoft Office System (VSTO).
The solution will insert an XML data island in a Word document. The data island contains the following XML fragment.
< customer id="01AF" >
< region district="Northwest" > < /region >
< /customer >
You bind the data island to an XMLNode instance named xln.
You need to update the region element with the following data.
< customer id="01AF" >
< region district="Southwest" > California < /region >
< /customer >
Which code segment should you use?

• A. if ( xln.ParentNode.NodeValue == "customer" & & xln.NodeValue [0]. CompareTo ("Northwest") == 0) { xln.NodeText = "California"; xln.ChildNodes [1].Text = "Southwest"; }
• B. if ( xln.ChildNodes [0].Text == "customer" & & xln.NodeText == "Northwest") { xln.NodeText = "Southwest"; xln.ChildNodes [1].Text = "California"; }
• C. if ( xln.ParentNode.NodeValue == "customer" & & xln.NodeText == "Northwest") { xln.NodeText = "Southwest"; xln.ChildNodes [1].Text = "California"; }
• D. if ( xln.ChildNodes [0].Text == "customer" & & xln.NodeValue [0]. CompareTo ("Northwest") == 0) { xln.NodeText = "California"; xln.ChildNodes [1].Text = "Southwest"; }

You are creating a custom workbook for Microsoft Office Excel by using Visual Studio Tools for the Microsoft Office System (VSTO).
The workbook will be used to import elements from an XML file named Expense.xml. The Expense.xml file is located in the C:\Data folder.
The schema of the Expense.xml file is stored in a file that is located at C:\Data\Expense.xsd. The schema contains the following XML fragment.
< xsd:element minOccurs ="0" maxOccurs ="unbounded" name=" ExpenseItem ">
< xsd:complexType >
< xsd:sequence >
< xsd:element name="Date" type=" xsd:date "/>
< xsd:element name="Description" type=" xsd:string "/>
< xsd:element name="Amount" type=" xsd:decimal " />
</ xsd:sequence > </ xsd:complexType > </ xsd:element >
You add the schema to the workbook by using a root element named root. You map the cells of the workbook to display the data from each element described in the XML fragment.
You need to ensure that the custom workbook validates the data against the schema.
Which code segment should you use?

• A. this.XmlMaps ["root"]. ShowImportExportValidationErrors = true;
• B. this.XmlMaps["root"].SaveDataSourceDefinition = true;
• C. Excel.XmlMap map = this.XmlMaps["root"]; this.XmlImportXml(@"C:\Data\Expense.xml", out map, true, Globals.Sheet1.Range["A1", Type.Missing]);
• D. Excel.XmlMap map = this.XmlMaps["root"]; this.XmlImport(@"C:\Data\Expense.xml", out map, true, Globals.Sheet1.Range["A1", Type.Missing]);

You are creating a document-level solution for Microsoft Office Excel 2003 by using Visual Studio Tools for the Microsoft Office System (VSTO). The customized workbook contains five worksheets. You add a LinkLabel control named Label to the first worksheet of the workbook. You need to create a LinkClicked event handler that displays the next worksheet in the workbook. Which code segment should you use?

• A. Private Sub Label_LinkClicked(ByVal sender As Object, _ ByVal e As LinkLabelLinkClickedEventArgs) Dim book As Excel.Workbook = CType(Me.Parent, Excel.Workbook) Dim sheet As Excel.Worksheet = _ CType(book.Sheets((Me.Index + 1)), Excel.Worksheet) sheet.ShowAllData() End Sub
• B. Private Sub Label_LinkClicked(ByVal sender As Object, _ ByVal e As LinkLabelLinkClickedEventArgs) Dim book As Excel.Workbook = CType(Me.Parent, Excel.Workbook) Dim sheet As Excel.Worksheet = _ CType(book.Sheets((Me.Index + 1)), Excel.Worksheet) sheet.Activate() End Sub
• C. Private Sub Label_LinkClicked(ByVal sender As Object, _ ByVal e As LinkLabelLinkClickedEventArgs) Dim book As Excel.Workbook = CType(Me.Site, Excel.Workbook) Dim sheet As Excel.Worksheet = _ CType(book.Sheets((Me.Index + 1)), Excel.Worksheet) s heet.Activate() End Sub
• D. Private Sub Label_LinkClicked(ByVal sender As Object, _ ByVal e As LinkLabelLinkClickedEventArgs) Dim book As Excel.Workbook = CType(Me.Site, Excel.Workbook) D im sheet As Excel.Worksheet = _ CType(book.Sheets((Me.Index + 1)), Excel.Worksheet) sheet.ShowAllData() End Sub
