The………ensures that the computer processes any previous lines of code that affect the interface’s appearance.
a) Refresh Method
b) Sleep method
c) Count method
d) Accumulator method
Explanation: The Refresh method ensures that the computer processes any previous lines of code that affect the interface’s appearance. The Refresh method’s syntax is Me.Refresh(), in which Me refers to the current form.
To delay program execution, you can use the…
a) Refresh Method
b) Sleep method
c) Count method
d) Accumulator method
Explanation: To delay program execution, you can use the Sleep method in the following syntax:
System.Threading.Thread.Sleep(milliseconds). The milliseconds argument is the number of milliseconds to suspend the program.
A millisecond is……. of a second.
a) 1/1000
b) 1/100
c) 1/10
d) 1/10000
Explanation: A millisecond is 1/1000 of a second; in other words, there are 1000 milliseconds in a second. A millisecond is smaller unit than second.
Which of the following statements pauses program execution for 1
second?
a) System.Threading.Thread.Pause(1000)
b) System.Threading.Thread.Pause(1)
c) System.Threading.Thread.Sleep(1000)
d) System.Threading.Thread.Sleep(100)
Explanation: To delay program execution, you can use the Sleep method in the following syntax: System.Threading.Thread.Sleep(milliseconds). The milliseconds argument is the number of milliseconds to suspend the program. A millisecond is 1/1000 of a second; in other words, there are 1000 milliseconds in a second. A millisecond is smaller unit than second.
A…………..displays a list of choices.
a) List box
b) Display box
c) Choice box
d) Check box
Explanation: A list box displays a list of choices from which the user can select zero choices,
one choice, or multiple choices. A list box is a graphical control element that allows the user to select one or more items from a list contained within a static, multiple line text box.
The number of choices the user can select is controlled by the list box’s ……
a) SelectionModeProperty
b) Select Property
c) Check Property
d) IsSelect Property
Explanation: The number of choices the user can select is controlled by the list box’s SelectionMode property. The default value for the property is One, which allows the user to select only one choice at a time. You can make a list box any size you want. However, the Windows standard for list boxes is to display a minimum of three choices and a maximum of eight choices at a time. If you have more items than can fit into the list box, the control automatically displays a scroll bar for viewing the complete list of items.
