Sorry that was too Brief.

accessing Form2["TextBox1"] will return a "Control" object so you can
access any general control properties like Width, Background, Name etc.

to access TextBox specific properties like Text, Placeholder etc use the
second method.

or you can make a function to access any control type use Object

Public Sub GetForm2Object(Name As String) As Object
  Return Form2[Name]


Then something like this will work...

GetForm2Object("TextBox1").Text = "This text"

The plus side of using Object is it works for ANY control and it's
the down side is the auto-complete only works if you specifically set the
object return type (Ie TextBox).

Public Sub GetForm2TextBox(Name As String) As TextBox
  if Form2[Name] Is TextBox Then Return Form2[Name]
  Error.Raise(Name & " is not a text box")
