When you specify Option Explicit on, you are obliged to declare all your
variables before using them.

It ensures all variables are declared before you can use them.

Hi ken,

Option Explicit means that you have to declare your variables before you
can use them.

Option Explicit On

Private Sub Button1_Click(. ..) Handles Button1.Click
i = 1
End Sub

--> Compiler Error. You have to declare i first: Dim i as Integer


Option Explicit Off

Private Sub Button1_Click(. ..) Handles Button1.Click
i = 1
End Sub

--> no compiler error.

There is only one thing to say about Option Explicit Off: do not use it.

It makes your code less safe and errors will be hard to detect.

Cheers

Place the caret on 'Option Explicit' and press the F1 key.
