In Delphi I have a routine that copies the currently  focused field from the
previous record that was entered before the current record. part of the code
is.
if  (activecontrol is tdbedit) then begin
  if  activecontrol.focused then
  fieldname:=(activecontrol as tdbedit).datafield;
Copyprevrecfield(fieldname);
this works in delphi. I don't know how to code the following line in
c++builder.
if (activecontrol is tdbedit)
I don't know what to substitute for the word ' is '.
I would appreciate any help ,thanks in advance

Hello Sol,

Litterally the above would become:
    if( dynamic_cast<TDBEdit*>(ActiveControl) )

But since in your snippet there's also at least one cast involved e.g.
(activecontrol as tdbedit).datafield, I would go for the following:

TDBEdit *dbedit = dynamic_cast<TDBEdit*>(ActiveControl);
if( dbedit ) {
    if( dbedit->Focused() )
        FieldName = dbedit->DataField;
    ... // and what else you have to do here

Hope this helps...;-))
