[Gambas-user] Trying to copy a collection with problems

[richard terry]

I'm working on the past history in my program.

I've a collection of these for aperson

ie person.pasthistory = the collection. I can add to this, iterate through it 
etc, no problem.

I want to copy this to keep a 'backup copy' to later check if any of the 
original data has been changed, and have tried this

In my frmPastHistory I have this:

Public PH_Copy As cPastHistory

When the form loads I use the data from the calling form (frmClinical) and do 
this:
 
public sub form_open()

PH_Copy = New Collection
 H_Copy = frmClinical.currentPatient.past_history


Now what happens is if I change anything in 
frmClinical.currentPatient.past_history  collection after that - it 
automatically changes in the Backup collection, so it seems that I'm just 
pointing to a memory address somehow, not creating an independant collection.

Any help appreciated. Hope this makes sense.

Regards

Richard.
