i want to change some values on the Active form by using
Dim frm As New Form1()

when i call this sub nothing is change ! way ?

Make L1, L2, L3, L4, L5 all public. They are private by default. You can then do what I think your trying to do.

Either that or you aren't talking about changing the values of the form you created with New Form1. If you mean that there is already a form open and you want to change its values then that wont work. When you call New Form1 you are creating a NEW form and then changing the values on it. Do a search and you should find lots of different ways of accessing an already opened forms properties.
