How to use & w/ a function parameter

In C++, you can pass a parameter to a function using &
so that the parameter you pass it is actually modified
and you do not have to return that parameter.
Like this:

Code:

---

void Function(int &x){
x = 100;
}

---

Then if you say:

Code:

---

int a;
Function(a);

---

Then a is actually 100 now.

Well, how do you do this in VB?

Try this.

Function Test(x)

x = 100

End Function

dim y

test y

'Now y=100

OK. I didn't realize it was that simple in VB.
Thanks

What you are talking about is passing variables by reference instead of by value - that's what the x& is, a reference to x.

In VB you use ByVal and ByRef to achieve the same thing. You've probably seen this in the declaration of API function calls.

For example:

Code:

---

Public Sub SetTo100(ByRef x As Integer)

---

That's exactly what I'm talking about.
Thanks.
