I've downloaded some samples on MSDN online library about the TAPI 3.0. However, I have no tapi3.dll, tapi3.h and the type library of tapi3 so that I cannot compile and test them. I've already known that tapi3.dll will be distributed on the Windows NT 5.0 but this is too late for me. Is there any pre release or beta version that I can use it to test the samples? Can anybody help me to find them?
