How to add an existing form of old project to a new project? Which extension type files to be added to work that existing form correctly?

I actually need frmContacts.vb(because a lot of textboxes and other controls are there) which I have added now to my New Project. Since it doesn't show any existing controls on form, I added other following files as well. Though there is no use. Please help.

1) frmContacts.vb
2) frmContacts.Designer.vb
3) frmContacts.Designer.vb


From the solution explorer, choose Add + Existing item + frmContacts.vb (Rest files will be copied automatically)

Thank you very much for the help.
