The best way to do it is pass a refrence of mainform object to the replace form as a parameter. Like:


do form replace with thisform


Then in the init method of replace form have:


LParameter voMainForm

** oMainForm is a custom Property of replace
ThisForm.oMainForm = voMainForm


Whenever you need to reference something on the mainform just use something like:

Thisform.oMainForm.SomeTextBox.Value = "New Value"
