Inside the form, you could write (c#)

this.Controls["Button1"].Text = "Changed";

I suppose, this could be the syntax in vb.net

Me.Controls("Button1").Text = "Changed"

EDIT: I don't know, if that would compile. @Binary Worrier is right

Button btn1 = this.Controls["Button1"] as Button;
btn1.Text = "Changed";

You need to look up the control in the controls collections, then cast it to the correct type. Is this in WPF , WinForms or ASP.Net?
