Ha, OK, indeed, nicer.
(But I like your first peace of code too.)
For the new code, maybe using a variant variable and create a new sumfield()
procedure:
procedure tmsebufdataset.sumfield(const afield: tfield; out asum: variant);
But for this, we need a variant-guru (I am beginner in variant
I want to change this peace of code

Re-hello Med.

Sorry but I dont understand.
Why do you want to sum ftinteger field into a currency var?
Why not sum ftinteger field into a integer var and after this, convert the
integer var into a currency ?

Please, give code example, it is really difficult to understand otherwise.

Hello Med.
> What do you think?
I would vote for this (set bCheck default to true for compatibility with
previous code):
procedure msebufdataset.sumfield(const afield: tfield; out asum: double;
bCheck: boolean = true);
And do it for all the other sumfield() (integer, currency, float, etc).
Hello Fred;
I think we have to change the code msebufdataset.pas in this case we have
not to duplicate the source (sumfiled ) in our project.
procedure msebufdataset.sumfield(const afield: tfield; out asum: double;
bCheck:boolean);
if bCheck then

Hello Med.
Here is tmsebufdataset.sumfield:
What about only comment the first line after begin ?
Is it what you want?
If so, maybe we can add a parameter (, nocheck) or create a new procedure
without check (procedure sumfield_nocheck).

With this below piece of code I do not want to test oField.datatype and doing

Hum, in msebufdataset.pas I see a "procedure checksumfield" not a "function

Hi all,
The demo Prj I sent later ( ifi,dbfilter ) use sumfield () . This
procedure can be used to add a sum column in dbgrid for example.
But this Martin's does not allow to mix field type. We can not use currency
or real var to sum an integer var
Procedure DoSum()
