VB .Net 2008
I have two open mdiChild forms (frm_Child_1 and frm_Child_2) and one mdiParent form (frm_Parent). The child forms are created and work correctly within frm_Parent.
I want to disable a control on frm_Child_1 when I select a menu option on frm_Parent. (I want to control frm_Child_1 from frm_Parent).
The brute-force method doesn't work (frm_Child_1.btn_Button.enabled = false). If frm_Child_1 happens to be active, then I can use the activeChild approach and that works, but frm_Child_1 isn't always the active child.
I think my brain has shut down, because this has got to be a "no-brainer"!
Thank you in advance for your help!
