2. You are creating a Windows Form. You add a TableLayoutPanel control named pnlLayout to the form. You set the properties of pnlLayout so that it will resize with the form. You need to create a three-column layout that has fixed left and right columns. The fixed columns must each remain 50 pixels wide when the form is resized. The middle column must fill the remainder of the form width when the form is resized. You add the three columns in the designer. Which code segment should you use to format the columns at run time?
A. pnlLayout.ColumnStyles.Clear()pnlLayout.ColumnStyles.Add(New ColumnStyle(SizeType.Absolute,
50.0F))pnlLayout.ColumnStyles.Add(New ColumnStyle(SizeType.AutoSize,
100.0F))pnlLayout.ColumnStyles.Add(New ColumnStyle(SizeType.Absolute, 50.0F))
B. pnlLayout.ColumnStyles(0).Width = 50.0FpnlLayout.ColumnStyles(0).SizeType =

6. You are modifying a Windows Forms application. The application consists of a main window with many different controls. All of the controls provide tool tips that use the default ToolTip control settings. One group of controls provides tool tips that show regulatory guidance for the user. Users want the wait time when reading the tool tips and navigating among them to be minimal. You need to ensure that this group of controls provides short delays before the tool tips appear. What should you do?
A. Set the AutoPopDelay property of the ToolTip control to 0 and the InitialDelay property to 100.
B. Set the AutomaticDelay property of the ToolTip control to 0.
C. Set the InitialDelay and ReshowDelay properties of the ToolTip control to 100.

New RunWorkerCompletedEventHandler(AddressOf _
CompletedHandler)
AddHandler bgwExecute.ProgressChanged, _
New ProgressChangedEventHandler(AddressOf ProgressChanged)
bgwExecute.RunWorkerAsync()
End Sub
