Hi Segey,

I have followed your advise :

It's a ProjecHook class. You attach it to each project through Project Info, Project tab, Project Class checkbox, ... Do not add it to the project itself. A backup will be performed each time you trigger Modify command through the project. It will not be triggered if you modify anything outside the project.

After that I have also rebuild the project.

Helas, when modifying a class, I cant find nowhere a VXK nor VTK file, even put a breakpoint in the ph_bakckup.querymodifyfile method. It never stopped, I suppose I should also 'tell' my classes, forms etc they need to call this ph_backup.vcx when opened for modification. Where how is this to be done? Only attaching the class in the project builder does not seem to solve the job.
Checked around on wiki, cant find any wording about this class. Seems I am on a dead-end.

Any further help is appreciated.

Thanks,

Koen
