Talking Forms

How do I get one form to talk to another? I am using VB5 and I want my password Login form to load a click event on the main form. I have a Boolean if then equation using a query def to check my password. If it is true I want the text boxes in the main form to load the users data. So if true then ??What??
Thanks

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
