Hi,
I want to be able to replace an application's .exe file from within the
application in response to a user action. As this cannot be done whilst the
application is still running, how can I make it start a batch file (or even
another exe) after terminating?

for Upgrader.exe to exit. Look up CreateProcess() in the win32 API for
information on how to do this. When Upgrader.exe starts, wait until
Application.exe terminates. You can define various ways of achieving
this, but the simplest is probably for Upgrader.exe to continually
attempt to overwrite Application.exe until it succeeds.

command-line parameter to Upgrader.exe, and then Upgrader.exe can call
OpenProcess() and WaitForSingleObject() to wait for Application.exe to
terminate, and then overwrite the file as needed.
