You
write a class named Employee that includes the following
code segment.
Private
m_EmployeeId As String
Private
m_EmployeeName As String
Private
m_JobTitleName As String
Public
Function GetName() As String
Return
m_EmployeeName
End
Function
Public
Function GetTitle() As String
Return
m_JobTitleName
End
Function
End
Class
You
need to expose this class to COM in a type library.
The COM interface must also facilitate forward-compatibility
across new versions of the Employee class. You need
to choose a method for generating the COM interface.
What
should you do?
A. Add
the following attribute to the class definition.<ClassInterface(ClassInterfaceType.None)>
_Public
Class Employee
B. Add
the following attribute to the class
definition.<ClassInterface(ClassInterfaceType.AutoDual)>
_Public Class Employee
C. Add
the following attribute to the class definition.<ComVisible(True)>
_Public Class Employee
D.
Define an interface for the class and add the following
attribute to the class definition.<ClassInterface(ClassInterfaceType.None)>
_Public Class EmployeeImplements
IEmployee

You are
developing a custom event handler to automatically print
all open documents.

event handler helps specify the number of copies to
be printed. You need to develop a custom event arguments

A.
public class PrintingArgs {
private
int copies;
public
PrintingArgs(int numberOfCopies) {
this.copies = numberOfCopies;
}

C.
public class PrintingArgs {
private
EventArgs eventArgs;
public
PrintingArgs(EventArgs ea) {
this.eventArgs = ea;
}public
EventArgs Args {get { return eventArgs; }}}
D.
public class PrintingArgs : EventArgs {
private
int copies;}

on other objects. You need to ensure that users of this
class can explicitly release resources when the class
instance ceases to be needed. Which three actions should
you perform? (Each correct answer presents part of the
solution. Choose three.)

Define the class such that it implements the IDisposable
interface.
C.
Create a class destructor that calls methods on other
objects to release the managed resources.
D.
Create a class destructor that releases the unmanaged
resources.
E.
Create a Dispose method that calls System.GC.Collect to
force garbage collection.
F.
Create a Dispose method that releases unmanaged resources
and calls methods on other objects to release the managed
resources.
Answer: B, D, F

need to write a code segment that performs the following
tasks:

You
are testing a newly developed method named PersistToDB.
This method accepts a parameter of type EventLogEntry.
This method does not return a value. You need to create
a code segment that helps you to test the method. The
code segment must read entries from the application
log of local computers and then pass the entries on
to the PersistToDB method. The code block must pass
only events of type Error or Warning from the source
MySource to the PersistToDB method.
Which
code segment should you use?
A.
EventLog myLog = new EventLog("Application", ".");
foreach
(EventLogEntry entry in myLog.Entries)
{
if (entry.Source
== "MySource")
{
PersistToDB(entry);
}
}
B.
EventLog myLog = new EventLog("Application", ".");
myLog.Source = "MySource";
foreach
(EventLogEntry entry in myLog.Entries)
{
if (entry.EntryType
== (EventLogEntryType.Error &
EventLogEntryType.Warning))
{
PersistToDB(entry);
}
}
C.
EventLog myLog = new EventLog("Application", ".");
foreach
(EventLogEntry entry in myLog.Entries)
{
if (entry.Source
== "MySource")
{
if (entry.EntryType
== EventLogEntryType.Error ||
entry.EntryType == EventLogEntryType.Warning)
{
PersistToDB(entry);
}
}
}
D.
EventLog myLog = new EventLog("Application", ".");
myLog.Source = "MySource";
foreach
(EventLogEntry entry in myLog.Entries)
{
if (entry.EntryType
== EventLogEntryType.Error ||
entry.EntryType == EventLogEntryType.Warning)
{
PersistToDB(entry);
}
