Re-hello Med.
sumfield is only implemented for double, currency, integer and int64:
procedure sumfield(const afield: tfield; out asum: double); overload;
procedure sumfield(const afield: tfield; out asum: currency); overload;
procedure sumfield(const afield: tfield; out asum: integer)
Hello Med.
Maybe you can complete the code checking all types that can be summed:
if (oField.datatype = ftinteger) then B1
else if (oField.datatype = ftcurrency) then B2
else if (oField.datatype = ftfloat) then B3
else if (oField.datatype = ftbcd) then B4
else if (oField.datatype = ftdate)
Hello Fred,
The blocks B1 and B2 after if are redondant that all .This procedure
works well.
if (oField.datatype = ftinteger) then
begin
B1 else B2

I agree and also it seems that using variant will make all the process
slower.
In the last code you give, in the first peace of code:
procedure tfrmbasePagefo.DoSum(oDbGrid: TDbwidgetgrid; iRow:integer);
VAR n:curre
