Question

I am trying to convert a VISUAL USER OBJECT that was once embedded on a window, into a DYNAMICALLY CREATED VISUAL USER OBJECT in a different window (same package).

The problem I’m getting is I can’t seem to be able to create an array of these objects without getting null references or reusing the same object over and over.

At the moment, when a user needs a new array element:

long ll_count
ll_count = UpperBound(iuo_backorders[])
iuo_backorders[ll_count+1] = uo_backorder    
lb_ok = iuo_backorders[ll_count+1].init('w_backorder_popup', '', '', '', 'd_backorder_popup', sqlca, useTransObj()) 

This reuses the same uo_backorder again and again.

Using: iuo_backorders[ll_count+1] = create uo_backorder returns null object references.

The user object is contained within another window (I think), so I’m not sure if I need to move the uo_ commands out into it’s own file in the PBL, or somehow change the references (new window is a child of the original, but unsure how that pertains to uo_)

All the functionality is already in the uo_, I just need to be able to work out

A) how to dynamically create a visual user object

B) how to then create an array of these objects.

Answer 1

To instantiate a visual object, you need:

windowname.OpenUserObject ( userobjectvar {, x, y } )

or

windowname.OpenUserObject ( userobjectvar, userobjecttype {, x, y } )

I’d expect that you’d be able to use iuo_backorders[ll_count+1] for your userobjectvar, but if not, just use a singular user object variable and assign it to the array element after it’s instantiated.

Good luck,

Terry.
