unable to extract array using CA_VariantGet1DArray

I have an AxtiveX control that fires an event passing an array of floats in a VARIANT. When the event fires I can see that the callback handler gets schedued in my CVI app. But when I try to extact the array with CA_VariantGet1DArray I get junk in my float array. The NumberofElements that is returned from the call is also wrong. It returns 1024 while the correct number is 256.

Thanks,

Dan
