Fit Form to Picture box

I have problem here. How I can fit the form in form 10 content into picturebox in form40?

Form40.Height = Form10.Height
Form40.Width = Form10.Width
Form40.Picture1.Height = Form10.Height
Form40.Picture1.Width = Form10.Height
Form40.Show

What are you trying to accomplish? Do you want to place a form inside of another form?

In form, have button,picturebox and so on. How I can place the form control to picturebox and fit the picturebox with form control

I am still not sure I understand you. Do you mean that you want the controls in the form to automatically resize when the form does?
