2. You are creating a Windows Forms application. You add an ErrorProvider component named
erpErrors and a DateTimePicker control named dtpStartDate to the application. The application
also contains other controls.
You need to configure the application to display an error notification icon next to dtpStartDate
when the user enters a date that is greater than today's date.
Which two actions should you perform? (Each correct answer presents part of the solution.
Choose two.)
A.For the Validating event of dtpStartDate, create an event handler named VerifyStartDate.
B.For the Validated event of dtpStartDate, create an event handler named VerifyStartDate.
D.In the Properties Window for dtpStartDate, set the value of Error on erpErrors to Date out of
range.
E.In VerifyStartDate, call erpErrors.SetError(dtpStartDate, "Date out of range") if the
value of dtpStartDate.Value is greater than today's date.
F.In VerifyStartDate, call erpErrors.SetError(dtpStartDate, null) if the dtpStartDate.Value
is greater than today's date.
Answer: (E AND A)

3. You are creating a Windows Forms application. The application loads a data table named dt
from a database and modifies each value in the data table.
You add the following code. (Line numbers are included for reference only.)
01 Dim row As DataRow
02 For Each row In dt.Rows
03 Dim col As DataColumn
04 For Each col In dt.Columns
05
06 Trace.WriteLine(str)
07 Next col
08 Next row
You need to format the string named str to show the value of the column at the time the data is
loaded and the current value in the column.
Which code segment should you add at line 05?
A.Dim str As String = String.Format("Column was {0} is now {1}",
row(col), row(col, DataRowVersion.Current))
B.Dim str As String = String.Format("Column was {0} is now {1}",
row(col, DataRowVersion.Default), row(col))
C.Dim str As String = String.Format("Column was {0} is now {1}",
row(col), row(col, DataRowVersion.Proposed))
D.Dim str As String = String.Format("Column was {0} is now {1}",
row(col, DataRowVersion.Original), row(col))
Answer: D

4. You are creating a Windows Forms application that includes the database helper methods
UpdateOrder and UpdateAccount. Each method wraps code that connects to a Microsoft SQL
Server 2005 database, executes a Transact-SQL statement, and then disconnects from the
database.
You must ensure that changes to the database that result from the UpdateAccount method are
committed only if the UpdateOrder method succeeds.
You need to execute the UpdateAccount method and the UpdateOrder method.
Which code segment should you use?
A.Using ts As New TransactionScope()
UpdateOrder()
UpdateAccount()
ts.Complete()
End Using
B.Using ts1 As New TransactionScope()
UpdateOrder()
Using ts2 As New
TransactionScope(TransactionScopeOption.RequiresNew)
UpdateAccount()
ts2.Complete()
End Using
ts1.Complete()
End Using
ts1.Complete();
C.Using ts1 As New TransactionScope()
UpdateOrder()
Using ts2 As New
TransactionScope(TransactionScopeOption.RequiresNew)
UpdateAccount()
ts2.Complete()
End Using
ts1.Complete()
End Using
D.Using ts As New TransactionScope(TransactionScopeOption.RequiresNew)
UpdateOrder()
End Using
Using ts As New TransactionScope(TransactionScopeOption.Required)
UpdateAccount()
ts.Complete()
End Using
Answer: A

5. You are creating a Windows Forms application. Initialization code loads a DataSet object named
ds that includes a table named Users. The Users table includes a column named IsManager.
You need to bind the IsManager column to the Checked property of a check box named
chkIsManager.
Which code segment should you use?
A.chkIsManager.DataBindings.Add("Checked", ds, "Users.IsManager")
B.chkIsManager.DataBindings.Add("Checked", ds, "IsManager")
C.chkIsManager.Text = "{Users.IsManager}"
chkIsManager.AutoCheck = True
D.Me.DataBindings.Add("chkIsManager.Checked", ds, "Users.IsManager")
Answer: A

6. You are creating a Windows Forms application. The application uses a SqlCommand object
named cmd. The cmd object executes the following stored procedure.
CREATE PROCEDURE GetPhoneList
AS
BEGIN
SELECT CompanyName, Phone FROM Customers
SELECT CompanyName, Phone FROM Suppliers
END
You need to add all returned rows to the ListBox control named lstPhones.
Which code segment should you use?
A.Dim rdr As SqlDataReader = cmd.ExecuteReader()
Do
While rdr.Read()
lstPhones.Items.Add((rdr.GetString(0) + ControlChars.Tab +
rdr.GetString(1)))
End While
Loop While rdr.NextResult()
B.Dim rdr As SqlDataReader = cmd.ExecuteReader()
While rdr.Read()
lstPhones.Items.Add((rdr.GetString(0) + ControlChars.Tab +
rdr.GetString(1)))
End While
C.Dim rdr As SqlDataReader = cmd.ExecuteReader()
While rdr.NextResult()
While rdr.Read()
lstPhones.Items.Add((rdr.GetString(0) + ControlChars.Tab +
rdr.GetString(1)))
End While
End While
D.Dim rdr As SqlDataReader = cmd.ExecuteReader()
While rdr.NextResult()
lstPhones.Items.Add((rdr.GetString(0) + ControlChars.Tab +
rdr.GetString(1)))
End While
Answer: A

7. A method in your Windows Forms application executes a stored procedure in a Microsoft SQL
Server 2005 database, and then executes a second stored procedure in a second SQL Server
2005 database.
You need to ensure that the call to the first stored procedure writes changes only if the call to
the second stored procedure succeeds. Installation requirements prohibit you from introducing
new components that use the COM+ hosting model.
What should you do?
A.Implement a transactional serviced component.
Add methods to this component to encapsulate the connect operation and execution of each
stored procedure.
Register and use this serviced component.
B.Add a TransactionScope block.
Connect to each database and execute each stored procedure within the TransactionScope
block.
Call the TransactionScope.Complete method if the call to both stored procedure succeeds.
C.Connect to both databases.
Call the SqlConnection.BeginTransaction method for each connection.
Call the SqlTransaction.Commit method on both returned transactions only if both stored
procedures succeed.
D.Add a TryCatchFinally block.
Connect to each database and execute each stored procedure in the try block.
Answer: B

8. You are developing an application that stores data about your company's sales and technical
support teams.
You need to ensure that the name and contact information for each person is available as a
single collection when a user queries details about a specific team. You also need to ensure that
the data collection guarantees type safety.
Which code segment should you use?
A.Dim team As Hashtable = New Hashtable()
team.Add(1, "Hance")
team.Add(2, "Jim")
