converting an existing VS MFC project to cuda project?

i have an existing MFC project,
and now i want to change some of its cpp files to call CUDA to boost its speed.
i want to compile using by emulator 'cus my cuda enabled video card is still on the way.
is there anyway can easily convert the MFC project to CUDA so that i can use the emuDebug?
thanks alot!

I tried to build CUDA kernel to a dll, and call the dll in MFC.

But be careful, all the files used in the MFC project have to be built with the same settings. I remember I had this problem before, coz I was comparing GPU computation efficiency with CPU, so I had two dlls included in the MFC project. One was GPU calculation, the other was CPU calculation. It did not work until I split this MFC project to two separate ones…
