form inheritance

Gene Buryakovsky

Hi all,

I'm new to this forum. I have three forms, the first one is the base form. The first form opens up a second and the second opens up a third. What I want to do is close the second when the third opens and allow the third to be on top of the first in a .showdialog(this) manner. Any suggestions?

Thanks,

It can be done easily by following way:

U please make the firstform is parent form and remaining two form as child form.

Then u open the 2nd form and before opening the 3rd form from 2nd form add the following code.

                foreach (Form f in this.MdiChildren)
                {
                    f.Close();

                }

and then open the third form

like this:

frm3 frmopen = new frm3();
                frmopen.MdiParent = this;
                frmopen.Show();

Dnt forget to make the first form as parent form
