You'll need to pass a reference to frm1 in the constructor of frm2. Then
you can call a frm1 public method to change the color.

makes sense .. but can you please show me some example, code ?

Class Form2
Private ref_frmForm1 as TypeofForm1

Public Sub New(ByRef Form1 as TypeOfForm1)
ref_frmForm1 = Form1
End Sub

Private Sub ChangeColorOnForm1()
ref_formForm1.PublicChangeColorFunction
End Sub
End Class


From Form1

Private Sub LaunchForm2()
Dim frmForm2 as Form2 = new Form2(Me)

frmForm2.show()
End Sub


Not sure if this is the best way, but it works.

The best way that I found of doing this was to have a startup module, and
place this code within it:-

Module Startup
Public myMainForm As frmApplication
Sub Main()
myMainForm = NewfrmApplication
Windows.Forms.Application.Run(myMainForm)
End Sub
End Module
