I'm working with D dinamic arrays but i need to work this data then with windows API's, these functions take void* as parameters. I pass params of type cast(void*)void[] and have had no problems at the moment. But, what if data in the array is not stored contiguously? windows functions will crash right?

Dynamic arrays are guaranteed to be stored contiguously (possibly it was 
a suggestion?). Casting to void* should work fine, but to be more 
portable, you should use (cast(void*) arr.ptr) (in case in future 
versions or on different platforms, the ptr and length feilds are reversed)
