I have an mdi parent and 2 child forms. Both are opened. Now When I try to pass a value, it gives me nullexception value.
Heres how I created MDI child forms:
Dim _a As New a _a.MdiParent = Me _a.Show() Dim _b As New b _b.MdiParent = Me _b.Show()
When both are opened with "a" having some text in textbox1 and "b" having empty textbox2. Now, I tried to get the value for "b" textbox from "a" as textbox2.text=a.textbox1.text. It gives me error. No value can be passed between child forms? How can I share the form events now?
