using instdrv.c in mfc application created by VC6

I have used VC6 to create a MFC application act as the GUI of my filter

However, I found that I don’t know how to make it recognize my instdrv.c.
i.e. I am unable to load the driver in it now.

What options should I set in VC6 to do that?
Can anybody help me? Thank you very much.
