I just joined this project and found the following error:
Non-modal forms cannot be displayed in this host application from an ActiveX DLL
(Error 406)

The application instanciates an ActiveX.exe which manages the data collection for a report. The x.exe then uses a print manager .dll to create a pdf etc. The progress form in this dll is non-modal, and this is apparently the problem.

Please help with the big picture as to why this architecture is not working.

Thank you for any assistance or reference pointers.
