Yes. Pages are up to date as of today.
I have not tried 2010 Express but it should work. I don't think 2005 had much support for making 64 bit code but I could be wrong. We used 2008 for CS5 so that should work as well (not sure about Express).
VC++ Express will not work if MFC code is used. MFC does not ship with the Express versions.
For some reason I compile the examples (And have a 8bf File) yet I can't see the Filter under thr 'Filter' menu.
Have this SDK samples been tested under Windows 7 64 Bit?
Yes, make sure you are building the x64 debug or release target and make sure you are placing the 8bf into the 64 bit build of Photoshop.
Does 32 bit work for you?
You're completely right.
I'm coming from AE where the target is automatically selected.
I switched to 64 and it works.
