Ok if the forms are in the same project dead easy.
In form one
txtusername = what the user types in
'
' You could open a record of courses and
' results as an example
'
rsCourse = db.openrecordset.....
load form2
'
' Here you can add anything you want to form2 because it is not yet displayed but stored in memory
'
form2.txtname = txtusername
rsCourse.MoveFirst
do
form2.cboCourse.AddItem rsCourse!Name
rsCourse.MoveNext
If rsCourse.EOF Then Exit Do
Loop
'
' Finally show the second form
'
form2.show (whatever model here)

Hope this helps
