In-Process and Out-of-ProcessCan someone suggest a site, page or article that explains in
understandable language the definition of In-Process, Out-of-Process, etc? Even better, to discuss the subject of 'process space', and how this relates to VB programming, or programming in general, etc.? Thanks! Webbiz Simply In-Process refers to your App and Out-of-Process refers to any other
App. For example if you have a VB Application and you start Excel (whether independently of your App or called internally by your App), Excel would be Out-of-Process.

The details (and actual terms) are contained in "Windows Virtual Memory Management", "Virtual Address Space", and "Processes and Threads". All relatively complex subjects but a place every Windows programmer has to go sooner or later.

Good reads. :)

Win32 API Programming with VB, if you happen to have that. (Steven Roman, O'Reilly Publ.) There are explanations of in-proc/out-of-proc in MSDN, but there doesn't seem to be a lot to say about that. They're pretty much self-explanatory. In VB terms they're options for COM components. You can make an in-proc DLL to hold functions, or you can make an out-of-proc EXE if you want to write a program with an automation interface.
