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 void DoOperation ( Office.IRibbonControl control) { if ( control.Tag == "Btn1") { //Btn1 click } else { //Btn2 click } }
• B. public void DoOperation (Control control ) { if ( control.Text == "Btn1") { //Btn1 click } else { //Btn2 click } }
• C. public void DoOperation ( Office.IRibbonControl control) { if ( control.Id == "Btn1") { //Btn1 click } else { //Btn2 click } }
• D. public void DoOperation (Control control ) { if ( control.ProductName.Equals ("Btn1")) { //Btn1 click } else { //Btn2 click } }

You are creating an add-in for Microsoft Office Outlook by using Visual Studio Tools for the Microsoft Office System (VSTO). You write the following lines of code. (Line numbers are included for reference only.)
01 Private folders As List(Of Outlook.MAPIFolder)
02 Private explorer As Outlook.Explorer
03
04 Public Sub CreateCollection()
05 explorer = Application.ActiveExplorer()
06 folders = New List(Of Outlook.MAPIFolder)
07 ProcessFolders(explorer.CurrentFolder)
08 End Sub
09
10 Public Sub ProcessFolders(ByVal folder As Outlook.MAPIFolder)
11 ...
12 End Sub
You need to ensure that the folders collection includes all the folders and subfolders within the selected Outlook folder.
Which code segment should you insert at line 11?

• A. folders.AddRange(folder.Folders) ProcessFolders(fldr) Next folders.Add(fldr)
• B. For Each fldr As Outlook.MAPIFolder In folder.Folders
• C. For Each fldr As Outlook.MAPIFolder In folder.Folders folders.Add(fldr) Next You are creating a document-level solution for Microsoft Office Word 2003 by using Visual Studio Tools for the Microsoft Office System (VSTO).
• D. For Each fldr As Outlook.MAPIFolder In folder.Folders ProcessFolders(fldr) Next

You are creating an add-in for Microsoft Office Word by using Visual Studio Tools for the Microsoft Office System (VSTO). You write the following lines of code. (Line numbers are included for reference only.)
01 try { 02 Word.Paragraph par =
this.Application.ActiveDocument.Paragraphs[2]; 03 par.Range.Text = ""; 04 } 05 ...
The application throws an exception if the active Word document does not contain a second paragraph.
You need to handle the exception.
Which code segment should you insert at line 05?

• A. catch (IndexOutOfRangeException ex) { // }
• B. catch (IOException ex) { // }
• C. catch (InvalidRangeException ex) { // }
• D. catch (COMException ex) { // }

You are creating a document-level solution for Microsoft Office Word 2003 by using Visual Studio Tools for the Microsoft Office System (VSTO).
You write the following lines of code in the solution.
Dim tag As SmartTag = New _
SmartTag("http:// MySmartTag/ST#MySmartTag", "My Tag") tag.Terms.Add("Bug") tag.Terms.Add("Error") tag.Terms.Add("Issue") Dim action As Action = New Action("Add Reference") tag.Actions = New ActionBase() {action} AddHandler action.Click, AddressOf Me.action_Click
You need to add the string "Reference: " before either "Bug", "Error", or "Issue" when the smart tag is clicked.
Which code segment should you use?

• A. Private Sub action_Click ( _ ByVal sender As Object, ByVal e As ActionEventArgs ) e.Properties.Write ( e.Range.Text , "Reference: " & e.Range.Text ) End Sub
• B. Private Sub action_Click ( _ ByVal sender As Object, ByVal e As ActionEventArgs ) e.Range.Text = "Reference: " & e.Range.XML (False).ToString() End Sub
• C. Private Sub action_Click ( _ ByVal sender As Object, ByVal e As ActionEventArgs ) e.Range.Text = "Reference: " & e.Text End Sub
• D. Private Sub action_Click ( _ ByVal sender As Object, ByVal e As ActionEventArgs ) e.Range.Text = "Reference: " & e.Properties.Read ("Text") End Sub
