Every form has an overloaded constructor, but one without
parameters amongst them. The code for the frmDetail, and
frmClient is as follows:
frmDetail:

Namespace Forms
Public Class frmDetail
Inherits System.Windows.Forms.Form
Protected _id As Int32
Protected _openMode As Constants.FormOpenMode
Private _detailName As String =
Constants.EmptyString
#Region " Windows Form Designer generated code "
#Region " Constructor"
Public Sub New()
MyBase.New()
'This call is required by the Windows Form
Designer.
InitializeComponent()
End Sub
Public Sub New(ByVal parentMDI As Form)
MyBase.New()
'This call is required by the Windows Form
Designer.
InitializeComponent()
Me.ParentMDI = parentMDI
End Sub
Public Sub New(ByVal detailName As String)
MyBase.New()
'This call is required by the Windows Form
Designer.

End Sub
Public Sub New(ByVal parentMDI As Form, ByVal

There isn't much code in those as I cannot add controls

Does your form class have a constructor that takes NO
arguments? That isnecessary for the form designer to be able to
instantiate it. Can you showus the code for the form class and information on the
constructors?
