Title: Difference with a Private Sub / Function
Post by: Clyde on May 02, 2006

Anyone know what the difference between using a sub or function with or without Private before it is used for please? And Is there any benefit with using it?

For example:

Code: [Select]

Sub ( ByVal x As Integer, ByVal y As Integer, ByVal c as Integer )
         'Dummy Sub
End Sub

Or:

Code: [Select]

Private Sub ( ByVal x As Integer, ByVal y As Integer, ByVal c as Integer )
          'Dummy Sub
End Sub


Cheers and many thanks,
Clyde.

Syntax

PRIVATE sub/function name


Description

Explicitly sets an individual sub/function to be private (instead of PUBLIC by default). This means the sub/function is only accessible within the module and is hidden to other modules. This means two subs/functions can have the same name, as long as they are private and are in seperate modules.

Subs/functions are private by default if the command OPTION PRIVATE is used, otherwise they are public by default.

If you have coded 2 librarys (*.bi) and if they use same name for one function/sub you can make those functions private for each separated module (.bi file).

Maybe, but I never used it until today :(

So it's like having a local subroutine / function for seperate includes, so it cant be used by other source listings that are shared.
