答
来自FastReport的Demos文件夹中的示例PrintStringList :
From example PrintStringList from FastReport's Demos folder:
var
Button1: TButton;
StringDS: TfrxUserDataSet;
frxReport1: TfrxReport;
StringList: TStringList;
procedure TForm1.Button1Click(Sender: TObject);
begin
StringDS.RangeEnd := reCount;
StringDS.RangeEndCount := StringList.Count;
frxReport1.ShowReport;
end;
procedure TForm1.frxReport1GetValue(const VarName: String; var Value: Variant);
begin
if AnsiCompareText(VarName, 'element') = 0 then
Value := StringList[StringDS.RecNo];
end;
