Pre-cache entire report?

rbuser

I have a report that does a lot of calculations.

I'd like to cache the entire report before the preview window is
displayed. Sort of run it from beginning to end without the user seeing
it and caching turned on, and only then bring up the preview window.

You can always create a 'dummy' device on the fly, run the report into
cache, then print it again:

uses
ppDevice;

var
lDevice: TppDevice;
begin

ppReport1.DeviceType := dtScreen;

lDevice := TppDevice.Create;
lDevice.Publisher := ppReport1.Publisher;
lDevice.PageRequest.PageSetting := psAll;

ppReport1.CachePages := True;
ppReport1.PrintToDevices;

lDevice.Free;

ppReport1.Print;

end;

FYI, you need to also use ppTypes, and change the create line to:

lDevice := TppDevice.Create(self)

but it does work. Thanks.

Of course, got a little too "on-the-fly" on that one. Great work figuring
it out...
