Roxanne,

In-Proc vs Out-of-proc is really only significant in terms of how things get loaded into Windows memory and what the server has available to it. In-proc (DLL) runs inside the address space of the client app. Out-of-proc (EXE) is a separate exe running on the machine with it's own address space and event queue. It doesn't really have too much bearing on exactly how you split your whole app into server and client modules. Either an EXE or a DLL would have the same amount of reuseability for you.

>So ok, I'm rethinking a piece of my VFP data warehouse application that I've been designing & planning forever. I was trying to formulate a question to hit my mentor with, which brought me here to make sure I knew what I was talking about (In Process vs. Out of Process).
