How to use CVI or VC function to exchange data between 78xxR and CVI or MFC exe

Question

with the Labview FPGA module,I write down th FPGA program on the 78xxR,and then use Labview to program for the data exchange between the host PC and the FPGA board. the question is that I have many programs written in CVI or MFC, I think if some c function can access the FIFO of the 78xxRunder under CVI or VC,for example, some functions available to copy data to or from the FIFO, then the old program can easily be change to use 78xxR board. can someone tell me?
now I use "Call Library Function Node" to load a dll that open shared memory created in CVI or MFC exe, use "Call Library Function Node"to read data from the shared memory and then use LV function to write data to FPGA; use LV "read/write control" node to Read data from the FPGA and then use "Call Library Function Node" to write data to shared memory. and a CVI or MFC exe read or write data to or from the shared memory, it works but isn't a good method, can some one has better method?

Hi, david2K:
     As there is no FPGA module supported for CVI or MFC, using "Call library Function node" is the only way to solve your problem until now.
    You have many programs written in CVI or MFC, so you can build the LabVIEW program as dll, and call it in CVI.
    Hope it helpful!
