Vista - Problem in DeSerialize a VB3 binary object to VB.Net

Hi,

I have a VB3 object which struct like this:


Type MyType
IntegerA as Integer
IntegerB as Integer
End Type

That object has been serialized to be a "MyType.dat" from the VB3 app.

Now I am rewriting that app to be a .Net application. I try to deserialize
the "MyType.dat" object by the following code:

... My .net Struc like this
Public Structure MyType
Public IntegerA as Integer
Public IntegerB as Integer
End Structure

... function is like this
Dim stream As FileStream
stream = New FileStream(path, FileMode.Open)
Dim formatter As New BinaryFormatter
Dim type As MyType
type = DirectCast(formatter.Deserialize(stream), Terminal)


I got an error when direct cast.
... Error as follow
Binary stream does not contain a valid BinaryHeader, 32 possible causes ...


Please tell me can it be done or what did I done wrong.
