How to dynamically replace / update forms modules ( fmx files) during Forms Runtime i.e while an application is still up and running ?
The forms executable modules ( fmx , mmx , pll / plx) cannot be replaced with newer versions if the modules are being accessed by end users.
The files are effectively in a read only state, having been locked by Forms Runtime.
All Forms Runtime sessions accessing the modules must be closed or terminated before a fmx , mmx , pll or plx can be updated.
