Which kind of component should I use?

[mogura]

I want to develop an ActiveX component that will validate IP addresses. If an invalid IP address is passed to the component, then the component will pass back the address 0.0.0.0. I want to use a deployment model that will allow the component to be used simultaneously by multiple applications and still provide the best possible performance. Should I use a local out-of –process.exe or an external in-process.exe. ? Or would a local in-process .dll be better?

Please Help!

Ok. First, to me, in process is a dll, and out of process is an exe. I don't know what an "external in process exe" is. If performance is your main issue, then in process (dll) is generally best, because it eliminates marshaling overhead. If you are working with something very complex, that might not be the case, however, this doesn't sound very complex. I would use a dll.

Validate in what sense, by the way? In that it is simply legitimate IP address (i.e follows the quad rules), or that it is a real IP address (eg it can be pinged)?
