Error as below
I can't view the designer form:

VB

Public Sub New()
       ' This call is required by the Windows Form Designer.
       Public Sub New()
       ' This call is required by the Windows Form Designer.
       InitializeComponent()
       ' Add any initialization after the InitializeComponent() call.
   End Sub

When debuging InitializeComponent() line show below Exception.

VB

Class not registered (Exception from HRESULT: 0x80040154 
(REGDB_E_CLASSNOTREG))

Class not registered (Exception from HRESULT: 0x80040154 (REGDB_E_CLASSNOTREG))

Solution 1

I would hazard a guess that you are using some COM component which is not registered. Is it throwing an exception at a specific line in InitialiseCompnonent or is InitialiseComponent not being entered at all ?
