I could not see any reason why I could not do a binary read from within a dll either. This is a snippet of what I was trying to do. It could write OK (I checked it in a hex veiwer) but raised an exception when I tried to read it back. Oddly it works when the solution is an exe.

When I try to read the structure back from the binary file.........
