Have a new task that requires that I use C++ again. Have been working in VBA, VB, and VB.net exclusively for the last 10 years. Last time I used C++ it was Borland and OLW. Know that VC7 supports managed, and unmanaged mixes. My new boss said it is important to stay in unmanaged mode. What Is the cost(s) of mixing managed with unmanaged in VC7? Will that change in "release 5"?
