[C++-sig] How to get output from python embedded in VC++

[Jian]

Hi Stefan,


Sorry for the late update. Changing to 'python35.dll' does not work. I guess there were something wrong when I complied the boost::python. I have been working on this for few days but I failed to find any error.


So now I'm trying to use the console created along with main MFC frame. It captures everything although it still looks not very good . I have found the way to optimize its behaviors as an embedded window control. then I could continue to focus on the main works.

Thanks a lot for your kind help.

Best Regards,


John.
