Intraweb/Thread safety

brekhof

Is FR 3 thread safe? I would like to use FR in a Intraweb build application but I understood that at least FR 2.5 is not thread safe.

FR3.0 is thread-safe.

But if I read the comments correctly in the newsgroups it is impossible to use it in products as kbmmw, I guess that would mean Intraweb also?

I don't familiar with kbmmw. FR3.0 is working in multi-threaded web server - see our server demo at fastreports.net/server

kbm & fr 3.x is the disccussion on the kbmmw forum.

I've readed the topic. To work with FR3 in multi-threaded environment, you should:
- use one instance of TfrxReport per thread.
- if you use export filters, you should create a separate instance of each filter per thread also.
- set the TfrxReport.EngineOptions.ReportThread property to thread that run this report.
- preferable to use end-user data components like TfrxADOComponents, so each report can have its internal datasets. By the way, such internal datasets can have the same username.

I have read in the fast report 3 FAQ :

3.8 What use FR in multithread program?

Before start the report need set: TfrxReport.EngineOptions.ReportThread
:= thread, in which is started FR and TfrxReport.EngineOptions.SilentMode :=
True;


"thread" is a TThread instance , It must be created ? How ? have you got
a sample ?



Thanks
