Hi,
Currently, National Instruments does not have any tools to program the Vertex II FPGA using Visual Basic. So far, you can only use LabVIEW and the LabVIEW FPGA module to program our RIO boards, like the PXI-7831R or the PXI-7811R. These boards containg an FPGA chip in it. You might be able to find some tools to program FPGA chips from VB if you make a search in Google.
I hope this helps!

BTW, you might want to post this type of questions next time under the Real-Time and Embedded category. You might get better feedback from other people that has had the same question.
