By "a Private Forms," do you mean a form that is marked on its (Properties) page "use only for responses"? To create a new instance of a custom form programmatically, use the Add method on the target folder's Items collection:
Set newItem = targetFolder.Items.Add("IPM.Post.YourFormName")
If it's a message form, use the Drafts folder as the target. If the target is a default folder, you can use the Namespace.GetDefaultFolder method to return it as a MAPIFolder object. To create an item in another person's mailbox, use Namespace.GetSharedDefaultFolder to get the MAPIFolder Otherwise, you can use the code at
