We made big effort for many years of development to make our VBcode Strict On. It's efficient and we try to stick to this. However now we integrated it with external dll working as COM object. And we are not able to keep option strict on anymore, is there any way round? Code:

Option Strict On                      
Public COMOBJECT As Object            'define variable as Object
COMOBJECT = CreateObject(CLSID)       'dispatch COM server
COMOBJECT.OpenFile                    'do whatever dll registered as com exposes
COMOBJECT.SaveFile                    'it all works with Option Strint Off
COMOBJECT.dowhatever                  'but not with Strict On

Error: Option Strict On disallows late binding.

Is there a way we can keep option strict On

I think this is essentially a duplicate - see http://stackoverflow.com/questions/635342/vb-net-turning-option-strict-off-in-line for a possible solution. – RobS Jul 02 '13 at 09:17

There is a complex answer, and it starts here: http://msdn.microsoft.com/en-us/library/aa645736%28v=vs.71%29.aspx – Alexander Jul 02 '13 at 09:36
@RobS no it's not duplicate. Guy there asks on how to make option Strict Off for part of the code. Her I asko how to make working with COM efficient. – Intelligent-Infrastructure Jul 02 '13 at 09:47
