multitheared dll and reports

Is it possible to run the REPORT FORM comand in a multi threaded dll?

I get Feature not Available. It runs fine in a single threaded dll or an
exe. The help indicates only the CREATE REPORT command is not supported in
dll's. I have tried with reportbehaviour=90 but doesn't help

I have found i can initiate a exe with createobject from the dll and run
reports from here - would this effect the call blocking in a multi threadedx
dll?

Any help appreciated

thanks

Greg,

No, it's not possible to run Report Form from a multi threaded dll.

Although I haven't tried it, I would expect that your MTDLL may well exhibit
call blocking behaviour as the exe you use to generate the report will use
the standard single threaded runtime libraries.

We ended up producing a seperate program (exe) for the reports. Then you
can use run /n and pass the report name and the database location as a
command line parameter and it will run as a seperate program and a seperate
thread. This has many advantages to it. If you have more than one program,
and the report program is written generic enough, then you can reuse it.
This is basically the only way to do multithreading in foxpro without using
a different language to create a dll.

Yes, you found the workaround for the problem. Just create an exe. COM
server with the REPORT FORM and from your vfp mtdll create the COM EXE
server and call the method that has the REPORT FORM. I haven't seen any
serious performance issues yet. It WILL NOT block other threads since each
thread would create its own server. Check out a demo of this architecture
here(PDF reports):

Thanks for all the replies. Nice to know other people are dealing with the
same issues
