Hi there :)
>To review: I'm trying to use vfp 9.0 COM objects plus htmllistener to produce asp pages on the fly. As was suggested "repo form" can not be used in a mtdll but does work in a com/exe which you can then call from the mtdll to exectute the "repo form" command.

I wrote reporting tool here in downloads called 'CodeRep' which can produce
custom html reports in more less the same manner as FRX does, without need to have/execute an actual FRX. It is class object for writing reports in code. In this case it might spare you of need to call an exe from MTDLL.
Sspeed wise it might be faster then VFP9 FRX.

Just supress few wait window (nowait) in class code that are used to show progress (in soure code) and you can start writing HTML reports in code suitable for MTDLL right away.

Best Regards
Sergio
