PipeTest.vcproj example Visual Studio 2008 Release Error

I’m new about Frontpanel & XEM3050.
I did release the pipetest example using wxWidgets & Visual Studio 2008,
but I got some errors.

I did setup property C/C++ General => Additional include directories &
Linker => General => Additional Library directories &
Linker => input => Additional Dependencies.

those are suitable for my wxWidgets, Visual Studio 2008, Microsoft SDKs Lib file
to release the pipetest example.

I got some errors like this.

Please let me know how can I solve this problem!
Thanks in advance!
