2. Critical Thinking “Recording” error
Extra credit (+1 point) to the first person who finds any material mistake in the vLabs or deck. timestamp will tell. Alternative ways of doing things do not count as errors.

3. Renaming a Project Unzip & make a copy of the project folder
Look inside the folder. Find the folder that contains the .vbproj file and many other files. Keep that folder, delete the ‘outer’ stuff.
Change the folder name to the new name.
Click on .vbproj to start VS and change all other filenames from inside VS.

6. Subs are a type of procedure
Public Sub MyProcedure()
Dim inputFromUser As String = ""
Dim userNum As Double = 0
inputFromUser = InputBox("Please enter a number to square")
userNum = Double.Parse(inputFromUser)
userNum = userNum ^ 2
ShowTheUser(userNum)
End Sub
Private Sub ShowTheUser(someValue As Double)
Range(“A1”).Value = "The result is " someValue.ToString("N0")
A procedure is a named sequence of steps
Purpose: reuse & simplify existing code
Good practice: shorter than a single screen
Sometimes it takes arguments
“Macro” is the old name for procedure

7. Local and global variables
Dim userNum As Double = 0
Public Sub MyProcedure()
Dim inputFromUser As String = ""
inputFromUser = InputBox("Please enter a number to square")
userNum = Double.Parse(inputFromUser)
userNum = userNum ^ 2
ShowTheUser(userNum)
End Sub
Private Sub ShowTheUser(someValue As Double)
Range(“A1”).Value = "The result is " someValue.ToString("N0")
Variables are names for physical places in your computer memory
Variables have a lifecycle
Variables have a scope

8. Functions are another type of procedure
input
Return a single value
Conceptually similar to the formulas in your worksheets
output
Private Function CalcInterest(r As Double, principal As Double, t As Double) As Double
Dim interest As Double = 0
interest = principal * ((((1 + r) ^ t) - 1))
Return interest
End Function

9. Argument Binding ‘ A function
Sometimes difficult to understand for beginners
‘ A function
Private Function CalcInterest(r As Double, principal As Double, t As Double) As Double …
‘ No binding
myInt = CalcInterest(0.05, 1000, 10)
‘ With binding (typical use)
myRate = 0.10
userPrincipal = 8000
years = 20
myInt = CalcInterest(myRate, userPrincipal, years)

10. Arguments vs. Globals
Arguments are short-term variables used as input to procedures (Subs and functions)
-best practice
-more efficient & less errors
Globals are variables defined outside of a Sub/Function
-Use globals if variables have an extended life, are small, and are used by many procedures
