MIS 216 Exam1 Review

Spring 2007

What to expect

Questions like those on the home works and on the quizzes Evaluate code Create code Multiple choice and True False on these and

terms and concepts Questions from Chapters 1-4

Questions will focus on important concepts and coding statements.

How about some specifics?

What should you focus on? What are the coding statements we’ve worked on

so far? How do each of these work? What are they used for? When would you use one vs. another? How can I manipulate string values?

Additional specifics

How do those statements appear in Visual studio? What is the syntax for the statements? Where do values get stored in textboxes etc? Where are variables declared? How are they

declared?

Variable LevelPrivate frmNew

Dim intAge as integerintAge=22

Sub btn1Dim intAge as integerintAge = 176

End Sub

Sub btn2Dim intAge as integerintAge = 822

End Sub

Sub btn3messageBox.show (intAge)

End Sub

If and Case StatementsDim sngPurchasePrice as single = 400.95

If (sngPurchasePrice < 100) ThenMessageBox.show ("Less Then 100")

ElseIf (sngPurchasePrice < 500) Then

MessageBox.show ("Less Then 500")Else

If (sngPurchasePrice < 1000) ThenMessageBox.show ("Less Then 1000")

ElseMessageBox.show ("Other Value")

End IfEnd If

End If

More with If StatementsDim strAnswer1 as string = "YES"Dim strAnswer2 as string = "YES"

If (strAnswer1 = "No") ThenIf (strAnswer2.Text = "No")

MessageBox.show ("Basketball")Else

MessageBox.show ("Hockey")End If

ElseIf (strAnswer1 = "No") Then

MessageBox.show ("Opera")Else

MessageBox.show ("Philharmonic")End If

End If

If/Case Statements

How could I create a statement that would do the following? I have a system with 3 tax brackets. I need to

determine who falls into which one and set the tax rate accordingly. The brackets and tax rates are $0-$5,000 (2%), $5,001 - $10,000 (4%), $10,001 + (6%). Assume that there is a variable (intAnnualIncome) that holds the data.

If/Case Statements

How could I create a statement that would do the following? Manages the withdrawl from a bank. If the person

withdraws less than they have in the bank, let them have the money. If they try to withdraw more than the have, block the access. Also, they cannot withdraw more than $250 at a time regardless of how much they have.

If/Case Statements

How could I create a statement that would do the following? In order to take a 300 level course, a student

must first take any two of three 200 level courses. Assume that the classes are 201, 205 and 210 and that the record of taking them or not are in blnClass201, blnClass205 and blnClass210.
