MessageBox.Show x new Form().Show();

I have a problem with my windows form application. I'm using a database, and in OnLoad of my application, I'm testing whether there is a content in a database. When I tell the user that there is a content using message box, it's all good, but when I set that new form is supposed to start (in case there's nothing in the database, they all show together. I would need one new Form().Show() and after I click OK (and it closes this.Close()) another one would show. is there a code for that? help me please, I'm desperate. thank you, vitek
