Paul,

Create the object in form1 just before you call form2 as in;

* Form1 code
oretval_email = createobject("MyEmailClass")

DO FORM form2 with oretval_email

In form2 add a property named oParmObj and in the form's Init put this code ...

* Form2 Init
LPARAMETERS toObj
Thisform.oParmObj = toObj

In the command button's click ...

* Command BUtton click
Thisform.oParmObj.property1 = "Somevalue"
...

Now when form2 is released the object in fomr1 will have the values you set in the button of form2. This is using a parameter object passed to form2 from form1.
