Hi,

I have this code:
Code: Pascal  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i   f :=
TField.Create(FDataList);  f.FieldName := 'calc';  f.FieldKind :=
fkCalculated;  f.SetFieldType(ftBoolean);  f.DataSet   :=
SQLQuery1.FieldDefs.Dataset;   procedure TForm1.OnCalc(DataSet:
TDataSet);begin  SQLQuery1.FieldByName('calc').AsBoolean := true;end;
But I get error "Invalid type conversion to Boolean in field calc"

Regards
