1. Visual Programming w/ Visual Basic
How to minimize risk emanating from the executioner

2. Function and Sub Review Void function and Value returning function
Function in VB is value returning
Sub in VB is Void function
Terms to keep in mind:
Parameter
Return Value

3. How to create function in VB
Function [Function_name] ( ByVal [F_Name] As [Type]) As [Type]
Return …
End Function
Everything just the same in C/C++

4. How to create Sub Sub [Sub_name] () End Sub
Do everything needed like in Void function in C/C++

5. Notice “ByVal” ?
Like C/C++, ByVal means ByValue and ByRef is ByReference
You just need to change ByVal into ByRef if you want to use reference by address
Mostly used in Swapping , etc.

6. Array To determine array just use “ ( ) “, not “ [ ] “ anymore
Dim Arr(3,3) As Integer , etc.
To recycle array just use ReDim
ReDim Arr(3,2) As Integer , etc.
The same, starts from 0

7. That’s all Keep practice
Never draw in your classroom even the executioner demands it. Never. Ever
Don’t lose hope. Even it is just a size of earwax
Never be alone in Lab session, unless you’re sure you’re God
Best advice: don’t ever retake this subject even you got C. Unless you got D or E
