The Code below will demonstrate the procedure of calling an MDIParent Method from an MDIChild Form.
In many cases where we use a MDIParent Form which has some menus disabled we require it to be enabled from a Login Form which is the MDIChild Form.The below code will help you solve the querry.
The MDI Parent Form :
A) Making the Methods Public
Public Sub Enable()
SpecialToolStripMenuItem.Enabled = True
B) Calling the Method from an MDI Child.This code will be written in the child form where you want the parent form method to be called.
Dim f As Form1 = Me.MdiParent
In this case the Form1 is the MDIParent Form.
The instance of Form1 f is Initialised with the Me.MdiParent which will get the reference of the MDI Parent Form.
