I prefer a separate method for updating the values, which prevents any object references that keep the forms dependent on each other.

Create a method in FormB that you call after instantiating FormB:
DoUpdateValues()

LPARAMETERS toFormA
THIS.txt.Value = toFormA.txt.Value
*-- etc

When calling FormA call this method and pass the form to the method:

DO FormB NAME loFormB
loFormB.DoUpdateValues(THIS)
