Refer to control on another form

[Jeff]

Hello All:

I have recently upgraded to VB .Net 2003 from VB6 and am
having a little trouble.

I have a MDI parent form that has a frame on it with a
list box on the frame. I open an MDI child form and the
frame on the parent form is still visible. What I want to
do is run an OLEDBCommand on the child form and use the
value of the item selected in the list on the parent form
as a parameter when the user clicks a button. I tried the
following but it doesn't work.

Sub On_Click
Dim frm as Form1 'this is the parent form
Dim ListValue as Integer

ListValue=frm.listbox1.SelectedValue("ID")

Dim frm as Form1 'this is the parent form
Dim ListValue as Integer

frm = ctype(me.mdiParent, form1)

ListValue=frm.listbox1.SelectedValue("ID")
.
.
.
End Sub

I don't remember the exact syntax, if it's SelectedValue
("ID") or SelectedText("ID"). But even with the correct
syntax this doesn't work.

I can do this using a public variable (set the variable in
the parent form when the user selects an item in the list
and set the ListValue variable in the child form equal to
the public variable, but this could get ugly.

So my question is how can I reference a control on another
form to retrieve it's value?

Any help is greatly appreciated.
