[DUG] Dbase File Data Update

[Jeremy Coulter]

Another thought would be to make the "JobNo" field an auto incrementing
field? I have to admit I cant remember too much about DBase but I am sure it
has auto incrementing fields. This would save you needing to calculate the
job number.

Subject: [DUG] Dbase File Data Update


I am trying to increase a value in a dbaseIII file. When I press the Inc
button, the referenced dbEdit field increases with each click. 
 
However on exiting the program, the tblData['Jobno']  does not reflect the
new value. 
 
 
>From data module.
 
begin
   tblData.open;
end;
------------------------------------
 
procedure TForm1.bIncClick(Sender: TObject);
 
var iCurrJobno:integer; 
 
begin
    iCurrJobno:=dm.tblData['Jobno'];
    iCurrJobno:= iCurrJobno+1;
    dm.tblData.edit;
    dm.tblData['Jobno'] := iCurrJobno;
end;
 
 
There are probably other ways of doing this, but I would like to know why
this does not work. 
 
Thanks Wallace
