You create an add-in for Microsoft Office Word 2007 by using Visual Studio Tools for the Microsoft Office System (VSTO).
The add-in contains a Ribbon1.xml file that customizes the Ribbon user interface (UI). The Ribbon1.xml file contains the following element.
< dropDown id=" CountryCodes " getItemCount =" GetItemCount "
getItemLabel =" GetItemLabel "/>
You write the following line of code in the add-in.
Private countries As System.Collections.ArrayList
...
countries = New System.Collections.ArrayList ()
countries.Add ("USA")
countries.Add ("JPN")
countries.Add ("IND"}
You need to bind the drop-down list to the countries collection.
Which code segments should you use? (Each correct answer presents part of the solution. Choose two.)

• A. Public Overloads Function GetItemCount _ ( ByVal control As Office.IRibbonControl ) As Integer Return countries.Count End Function
• B. Public Overloads Function GetItemLabel ( ByVal control As _ Office.IRibbonControl , ByVal index As Integer) As String Return countries(index) End Function
• C. Public Overloads Function GetItemCount _ ( ByVal control As Office.IRibbonControl ) As Integer Return countries.Capacity End Function
• D. Public Overloads Function GetItemLabel ( ByVal control As _ Office.IRibbonControl , ByVal index As Integer) As String Return countries.ToString () End Function

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 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)
• B. 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)
• 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.Add(ExpenseData) 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 Microsoft Office Word 2007 by using Visual Studio Tools for the
Microsoft Office System (VSTO). The add-in customizes the Ribbon user interface (UI).
The add-in contains a file named Ribbon1.xml that has the following markup for two buttons.
<button id="Btn1" onAction =" DoOperation " />
<button id="Btn2" onAction =" DoOperation " />
You need to create a callback function that runs different code for the buttons.
Which code segment should you use?

• A. Public Sub DoOperation ( ByVal control As Control) If control.Text = "Btn1" Then 'Btn1 click Else 'Btn2 click End If End Sub
• B. Public Sub DoOperation ( ByVal control As Office.IRibbonControl ) If control.Tag = "Btn1" Then 'Btn1 click Else 'Btn2 click End If End Sub
• C. Public Sub DoOperation ( ByVal control As Office.IRibbonControl ) If control.Id = "Btn1" Then 'Btn1 click Else 'Btn2 click End If End Sub
• D. Public Sub DoOperation ( ByVal control As Control) If control.ProductName.Equals ("Btn1") Then 'Btn1 click Else 'Btn2 click End If End Sub

You create an add-in for Microsoft Office Excel 2007 by using Visual Studio Tools for the Microsoft Office System (VSTO). The add-in must be installed on 100 computers that run Windows Vista and Microsoft Office 2007 Professional Edition. You need to configure the computers to run the add-in. What should you install on the computers?

• A. Microsoft .NET Framework 1.1
• B. Microsoft .NET Framework 2.0
• C. Microsoft Office Primary Interop Assemblies
• D. Microsoft VSTO Runtime
