37. Which design time property setting should be used on an object named UserInputTextBox in order to make the insertion point appear in the object when the form first appears?
D) -----TabIndex property set to 0
Logic: The object with the lowest tab index has the focus set to it first at run time. Tab index is configured in design time.First you Plan with the 3 step process-1. Design the user interface-2. Plan the properties-3. Plan the basic codeThen in actual programming you use a 3 step process again. (Page 7)-1. Define the user interface //The reason this is the answer is after you plan, this is the first step in actual programming-2. Set the Properties-3. Write the basic code

What happens when a Sub procedure finishes executing?

|
|
Why has the advent of graphical user interfaces (GUIs) influenced the shift from procedural programming to object-oriented/event-driven programming?
|
Although GUIs have made programs friendlier and easier to interact with, they have not simplified the task of programming. GUIs make it necessary for the programmer to create a variety of on-screen elements such as windows, dialog boxes, buttons, menus, and other items. Each of these on-screen elements can be modeled in software by an object.

10. If a project runs, but the results are not correct, the result will be a(n) _______.
A) logic error
Logic: A syntactical error would most likely prevent the program from running in the first place (for the program would not compile properly). A run-time error would be the program attempting to execute illegal code that would crash the program. A program producing the wrong results is a logical error in writing the code.

From what you have read in this chapter, describe the difference between a label control and a textbox control. When is it appropriate to use one or the other.

A Label control is used to display text information. The user cannot enter a value into a Label control, or change the value it displays. The user can, however, enter information into a TextBox control. It is appropriate to use a Label control when displaying data that the user cannot change. It is appropriate to use a TextBox control when the user must enter data.
