Can you create a contructor in form2 which takes a Form Object?

class form2 : Form
{
   private Form calledByForm
   public form2 (Form prevForm)
   {
      this.calledByForm = prevForm;
   }
 
   private CallPrevForm()
   {
      calledByForm.Show();
   }
}

Well, I am not sure how you are generating this error, maybe if you pasted the code from where the error is generating would be a great idea, especially when you consider yourself to be new to this.

What I presume is that you are calling the method and attribute from form 1

If that is the case then when you are instantiating form2 from form1

you should be doing something similar to the foll

form2 frm2 = new form2(this);

and the method CallPrevForm() is supposed to be called from form2, if you want form1 to call it then make it public

This is a common problem posted in this forum. The reason why most people run into this problem unfortunately is poor program design. Forms do not drive a program and should not be the first components of a program. Forms are only one possible input/output platform and should be designed last. Program design should instead be done using objects.
