[Openroad-users] Accessing dynamically created fields

[James Higson]

Hi all,
 
I am using OR4.1SP3.
 
I have a StackField object which has a datatype of a userclass.  I have then
created several instances of this StackField and grouped them into a second
StackField then grouped this into a ViewPort.  In effect, I have mimmicked a
TableField.  I am then dynamically appending instances of the first
StackField to the second StackField by duplicating the first instance at
runtime.  I hope you are following me so far.  The instances are then named
r001, r002, ... r00n.
 
I can reference the instances by using either:
    FieldPtr =
CurFrame.TopForm.FieldByFullName(FullName='r'+RIGHT('000'+VARCHAR(i),3))),
or;
    ExprPtr =
CurFrame.Scope.CreateDynExpr(String='r'+RIGHT('000'+VARCHAR(i),3))).
 
The problem I have, is that CreateDynExpr only works for the instances of
the StackField that were statically created on the form.  The dynamically
created instances return a NULL reference.  FieldByFullName works for the
dynamically created instances.  I want to set the instances to a row in an
array by using:
    ExprPtr =
CurFrame.Scope.CreateDynExpr(String='r'+RIGHT('000'+VARCHAR(i),3)));
    ExprPtr.SetValue(Value = a[i]);
 
I would have thought that CreateDynExpr should work for dynamically created
instances as well.  Can anyone see another way to do this?
 
Thanks,
James
