OpenNI on a 64-bit windows

[WengYi]

I have installed the driver and etc and NIviewer works for me.

However, when I try to write my own code (eg. saving it into an
image),

I run into this error:

This was what I did:

In the C/C++ section, under the General node, find the "Additional
Include Directories" and add "$(OPEN_NI_INCLUDE)".
In the Linker section, under the General node, find the "Additional
Library Directories" and add "$(OPEN_NI_LIB64)".
In the Linker section, under the Input node, find the "Additional
Dependencies" and add OpenNI64.lib

What went wrong?

Thank you and greatly appeaciate if anyone knows the solution to
this :)

Hi Weng,

You are building your project for Win32 platform; try switching to x64
target - in my case this resolved a similar problem.

Regards,
Yuri.
