DELPHI4.0 当多次预览报表(quickrep)时(如15次),出现如下错误
metafile is not valid
canvasdo
es not allow drawing
out of system resources
需退出软件后再进入,则预览9次出错,以后逐次减少
有时错误造成需重新启动计算机,才可预览,救救这个可怜的程序吧!!!
附∶预览程序
with TwtPrvform.Create(Application)do
begin
wtQRPreview.QRPrinter := TQRPrinter(Sender);
CurRep := quickrep1;
Show;
end;
调用程序
with Trptform.create(self)do
begin
QuickRep1.print;
QuickRep1.Free;
free;
end;
