Can we subclass a window created by another process? If so, how?

Since you use the word "process" I assume you are working on either
Win95 or WinNT. The answer is for all practical purposes "NO", not if
you mean with traditional instance subclassing. You can however use a
hook via the SetWindowsHookEx() API. -steve

Subclassing window

There is an Article in MSDN (Safe Subclassing in win32) and a KB article
"HOWTO: Subclass a Window in Windows 95" ID: Q125680.
Check them out. Let me tell you, it aint easy!!!.. if possible, consider
some sort of inprocess subclassing or OLE..

This cannot be done in 32 bit windows due to the fact that each
process has a separate address space.

There was an article in MSJ a couple of years ago that describes how to
INJECT your DLL into the address space of another process. It's not easy,
but the article includes a DLL that boils it down to a simple function call.
Check the MSJ site on http://www.microsoft.com/msj, search for INJECTLIB (I
think)

Jeff Richter also spends a fair amount of time discussing this in "Advanced
Windows."
