Solution 1

It happens because you disable the Button inside the Form2_Load-method. This method is called when the Form is activated.
Why don't you disable the Button1 of Form2 with the Designer (or the Designer-Script) ?

i changed to disable with designer, but still not working :(

And you have deleted the Code-line inside the Form_Load-method ?
But I'm also a little confused with your descriptions ... which Button from which Form should enable which Button on which Form. I suggest you use unique descriptions.
Basicly your code must work if it's called - but it is possible that another method compromise it ...

Solution 2

Private Sub ButtonB_Click(sender As Object, e As EventArgs) Handles ButtonB.Click
Form1.ButtonA.Enabled = True
end sub
