6.Use VB.NET's Dynamic Help.
7.Explain the uses of the Courier New and Wingdings fonts in VB.NET programs.
8.Enable and disable the Auto Hide feature.
9.Write statements that change properties of a control or form.
10.Write code for the events Click, TextChanged, Leave, and Enter.
11.Make use of the Class Name box and the Method Name box components of the

14.Write code using numeric expressions.
15.Write code using the Add and Clear methods for a list box.
16.Interpret numbers expressed in scientific notation.
17.Use the With block to simplify code.
18.Use the Dim statement to declare variables of type Double or Integer.
19.Use the Dim statement to assign an initial value to a variable.
20.Create meaningful variable names that follow naming conventions.
21.Write code that increments the value of a variable using either an assignment
statement of the form var = var + n or the special operator var += n.
22.Explain and use the built-in functions Math.Sqrt, Int, and Math.Round.
23.Declare multiple variables with a single Dim statement.
24.Use the level of precedence of arithmetic operators to evaluate and write arithmetic
expressions.
25.Give examples of the three types of programming errors: syntax errors, run-time
errors, and logical errors.
26.Use assignment statements and the Add method to work with strings.
27.Use text boxes for obtaining input and displaying output.
28.Use the data-conversion functions CDbl, CInt, and CStr.

value of a string.

numbers in familiar formats.
38.Use String.Format to display output in tabular form.
39.Use the StreamReader object to input data stored in a file.
