You have just graduated from college, now you are serving the internship as the software developer in an international company. According to the requirements of the company CIO, you're developing a server. You are developing a method to hash data with the Secure Hash Algorithm. The data is passed to your method as a byte array named message. You have to use SHA1 to compute the hash of the incoming parameter. Besides this, you have to place the result into a byte array named hash. In the options below, which code segment should you use?

• A.Dim objSHA As New SHA1CryptoServiceProviderDim hash() As Byte = NothingobjSHTransformBlock(message, 0, message.Length, hash, 0)
• B.Dim objSHA As New SHA1CryptoServiceProviderDim hash() As Byte = objSHA.ComputeHash(message)
• C.Dim objSHA As New SHA1CryptoServiceProviderobjSHA.GetHashCode()Dim hash() As Byte = objSHA.Hash
• D.Dim objSHA As New SHA1CryptoServiceProviderDim hash() As Byte = BitConverter.GetBytes(objSHA.GetHashCode)

You work as the developer in an IT company. Recently your company has a big customer. The customer runs a large supermarket chain. You're appointed to provide technical support for the customer. There's an SQL query that takes one minute to execute. You execute the SQL query asynchronously by using the following code:
IAsyncResult ar = cmd.BeginExecuteReader();
When you're executing the SQL query is executing, you have to execute a method named DoWork(). It takes one second for the method to execute. When the SQL query is executing, DoWork() must run as many times as possible.
In the options below, which code segment should you use?

• A.while (!ar.IsCompleted) { DoWork();}dr = cmd.EndExecuteReader(ar);
• B.while (Thread.CurrentThread.ThreadState == ThreadState.Running) { DoWork();}dr = cmd.EndExecuteReader(ar);
• C.while (ar.AsyncWaitHandle == null) { DoWork();}dr = cmd.EndExecuteReader(ar);
• D.while (!ar.AsyncWaitHandle.WaitOne()) { DoWork();}dr = cmd.EndExecuteReader(ar);

• C.SHA1 sha = new SHA1CryptoServiceProvider();sha.GetHashCode();byte[] hash = sha.Hash;
• D.SHA1 sha = new SHA1CryptoServiceProvider();byte[] hash = null;sha.TransformBlock( message, 0, message.Length, hash, 0);

You have just graduated from college, now you are serving the internship as the software developer in an international company. According to the requirements of the company CIO, you create a mobile Web Form which contains a mobile Calendar control named calDate. The customers want you to capture the date that users choose from the Calendar control. What action should you perform?

• A.Create an event handler for the OnSelectionChanged event of the calDate control. In the
  event handler, read the Calendars SelectionDate property.
• B.Create an event handler for the OnInit event of the calDate control. In the event handler, read the Calendars VisibleDate property.
• C.Create an event handler for the OnInit event of the calDate control. In the event handler, read the Calendars SelectionDate property.
• D.Create an event handler for the OnSelectionChanged event of the calDate control. In the event handler, read the Calendars VisibleDate property.
