I did this once for my project  to close one application and open another application       System Threading Thread newThread      Form1 frmNewForm   new Form1      newThread   new System Threading Thread new System Threading ThreadStart frmNewFormThread    this Close            newThread SetApartmentState System Threading ApartmentState STA           newThread Start      And add the following Method  Your newThread Start will call this method       public void frmNewFormThread                   Application Run frmNewForm

if you just want to close form1 from form2 without closing form2 as well in the process  as the title suggests  then you could pass a reference to form 1 along to form 2 when you create it and use that to close form 1  for example you could add a   public class Form2   Form       Form2 Form1 parentForm  base                 this parentForm   parentForm             Form1 parentForm                field and constructor to Form2  if you want to first close form2 and then form1 as the text of the question suggests  I d go with Justins answer of returning an appropriate result to form1 on upon closing form2

Your question is vague but you could use ShowDialog to display form 2  Then when you close form 2  pass a DialogResult object back to let the user know how the form was closed - if the user clicked the button  then close form 1 as well

This works   Private Sub Button1 Click ByVal sender As System Object  ByVal e As System EventArgs  Handles Button1 Click     Me Hide       Form2 Show
