I am trying to use binary serialisation to store and retrieve objects from
file and to/from a database. This all seemed to work fine when running in
the IDE, but when I build a release version of my application, it no longer
reads the data from the files that I have generated, nor from the database
that I have written to with the debug version.I don't get any error
messages, I just get all my properties set to nothing.. This application is
likely to be under continual development for some time, so I will need to be
able to access the same data with both the debug and release versions.

Any suggestions appreciated.
TIA
Phil.

PS. I have also tried using the XMLSerializer (I would prefer binary as it
is more compact for storage in a database), but I get an error indicating
that multi-dimensional arrays are not supported.

Seems to be working now.
I think it may have just have been an issue with file locations.

Well I thought it had started working, but it's failing again now.
When I run from the VB IDE it all works fine, and when I run my deployed
application it all works fine, but if I try to use a file created when
running under the IDE it will not deserialise properly when running my
deployed application and vice versa.

Any suggestions appreciated.

My serialisation code is very simple:

' serialise:
With New BinaryFormatter
.Serialize(MyStream, MyObj)
End With

' de-serialise:
MyObj= (New BinaryFormatter).Deserialize(Stream)

What happens? You get an object back but its corrupt? You get an exception?

If you get an exception what is it?

Cheers,

Adam.

No exception. I get an object but all the properties are set to Nothing. The
properties are all arrays of Double or arrays of String.
