Category: Variables and Constants
In Visual Basic there are some controls properties that return you a Boolean value which can be as condition in the testing. For example, option buttons returns true when they are selected and returns you false when they are not.
These Boolean variables can be tested as follows:
If optFreshman.Value = True Then
mintFreshmanCount = mintFreshmanCount + 1
ElseIf optSophomore.Value = True Then
mintSophoreCount = mintSophoreCount + 1
End If
