I got these error when I try  using Poco library with Fltlib together,

What I did is : I build the poco library sample fine.
                        I build the minifilter  sample  fine.

  I want create my project, merge these 2 project together, I meet an issue is Platform toolset is different.  I try find the way it worked.  using Platform  toolset v110. 

but got these 2 exception.   the type missing is defined in "fltuserstruct.h", 

Why merge got exception...

Finally , I found I need put include "fltUser.h" ahead of poco*.h 

It is good to find something work.
