Question

I get the “Undeclared identifier” in a pprocedure I created called submit.

procedure submit;
begin
if ebMain.Text='exit' then
fmMain.Close;
end;

Really simple. The compiler tells me ebMain is undeclared. I ca fix this by putting “fmMain.” in front of it but I never had to do this in delphi 7.The edit box(ebMain) is on the main form(fmMain). The procedure header is placed just under the “uses”. What’s wrong?

Answer 1

submit() is not a member of your TfrmMain class, so it does not know what ebMain is. You need to either:

1) make submit() be a member of your form’s class (which you should do anyway because all it is doing is accessing members of TfrmMain):

procedure TfrmMain.submit; 
begin 
  if ebMain.Text='exit' then 
    Close; 
end; 

procedure submit; 
begin 
  frmMain.submit;
end; 

2) prefix ebMain with the form’s global frmMain variable (like you are already doing for Close()):

procedure submit; 
begin 
  if frmMain.ebMain.Text='exit' then 
    fmMain.Close; 
end; 

Yes, you would have had to do this in every version of Delphi, including D7.
