Passing a hold value to another form

In vb.net
I have form1 which has a dropdown box when the item is selected it is placed in a holdfield
I need to pass that value of the holdfield to form2
to use in a query

How do I pass that value in order to use it?

A code sample would be very helpful

thanks in advance

in form2, you can programatically access elements in form1.

in form2:

Dim val as String
val = form1.holdField.Text
