Your question is very unclear.

Stricly speaking, the only way to access this card and IRQ5 is via a DEVICE DRIVER or of you are running Win9x, a VxD.

VC++ 6 make ONLY 32-bit code and the only way to directly access hardware in 32-bit code is via a driver running in RING0.

Get the Windows DDK as a starting point.
