Best case using ByRef

[Roland S.]

Hello Forum,

i have some stupid question: When is the best case to use the keyword ByRef for variables?

Becaus i am not shure every time, i have to ask this question to all the people here.

regards

it's used in function parametres

1) when you need change value of parameter inside func and return this changed value back through th

at parameter variable2

2) when you pass array as function parameter - in this case there isn't done copy of all array to local variable --> this is for speed optimalization
