fastreport2.5 中的 LoadFromBlobField 函数适用用于ado控件吗
如下为什么不可以啊
frReport1.LoadFromBlobField(adoquery.FieldByName('sj_file'));
frReport1.ShowPreparedReport;

查看 TfrDesigner 组件. 它有几个必需的事件: OnLoadReport 和
OnSaveReport. 这里有一小段代码例子:
procedure TForm1.frDesigner1LoadReport(Report: TfrReport;
var ReportName: String;
var Opened: Boolean);
begin
with MyOpenDialogdo
begin
Opened := ShowModal = mrOk;
if Opened then
begin
Report.LoadFromBlobField(…);
ReportName := …;
end;
end;
end;

bbscom 你好
frReport1.LoadFromBlobField(Tblobfield(adoquery.FieldByName('sj_file')));

frReport1.ShowPreparedReport;
这种方法我也试了还是显示不出报表来啊
