ByVal var As String

[Shapper]

Hello,

What is the difference between using in a function:

Sub Change_Culture(ByVal newCulture As String)

Or

Sub Change_Culture(newCulture As String)

The difference is the ByVal.

Thanks,
Miguel

There is none. parameters are passed by value by default. In previous
version of VB the default was ByRef.

Actually, there is 1 difference: readability. Those unfamiliar with VB.Net
might not know what the default bahaviour is, hence you should always put
it.

Nothing - except clarity.

ByVal is the default in .NET. To be as clear as possible, you should
specify ByVal (especially when working with developers coming recently from
classic VB where the default was ByRef).

They are functionally identical since parameters are ByVal by default.

Thanks,

I wasn't sure but the truth is that the effect was the same using ByVal
or Not.

Thanks once again,
Miguel
