Hi,
Getting the error message:-
Additional information: BinaryFormatter Version incompatibility. Expected Version 1.0. Received Version 335546368.-16770048.
From the code below, in the PictureFormat method - which is the delegate for the Format property of the image - the error occurs when the memory stream is deserialized. The graphic is stored in an Access database as a bitmap.
I've read various articles about how this error message arises but none seem applicable. I even tried converting a string to bytes and deserializing, this worked fine.
Many thanks,
Glyn.
