I have a question:
In mainform 's source code, how can I know which other forms are showed, and how can I control these forms from mainform, such as calling a method in each of these forms?

Plz help me!
Thank you very much.

within MDI form use this code
child form is MyChildForm

MyChildForm childForm = null;
    foreach(Form f in this.MdiChildren)
          if(f is MyChildForm)
               // found it
                childForm = (MyChildForm) f;
      if( childForm != null)
           childForm = new MyChildForm();
           childForm.MdiParent = this;
