CrystalDecision s.CrystalReport s.Engine.OutOfL icenseException

[Stijn Lambert]

Hi all,

I am having some problems with Crystal Reports 9 for Visual Studio .NET ...

I have a multithreaded application that prints reports in several threads
(based upon incoming requests on a queue ...), 1 report per thread. When
multiple threads are launched, I get the following error:
CrystalDecision s.CrystalReport s.Engine.OutOfL icenseException

This is due to limitations in the Crystaldescisio ns object-model. (Thats's
what I understand from reading
http://www.crystaldecisions.com/prod...easurement.asp
) There it is stated that only 3 concurrent requests can be processed at the
same time.

Theys say that, for increased scalability, you can upgrade to Crystal
Reports 9 Advanced, where there is an "open deployment license". (This means
basically that this limitation to 3 concurrent reports is still there, but
that additional requests are queued internally, instead of generating the
exception) (That's what I understand from
http://www.crystaldecisions.com/prod...ingchanges.asp
)

I have been toying around with a decompiler, but don't seem to find anything
usefull.

Does anybody know any workaround or hack for this ?

Thanx,
