Hi Jonathan,

I would start by seeing if your LC code can be optimized so the time it takes per screen is acceptable. There are many small changes a person can sometimes make to code that causes dramatic speed increases.

Or is the bulk of the time spent in areas LC can't address natively? Maybe that's why you want to go toward an external.

Thanks -

Hello fellow LiveCoders,

I need to write an external and it needs to be fast. It is for extracting
images from a green screen. I wrote a good algorithm for this in LiveCode,
but it takes 20-30 seconds to handle all of the data processing. I want to
use C++ for speed advantages.

I tried following the desktop externals tutorial that LiveCode uses, but it
seems that the external generator that LiveCode offers does not work
properly with Visual Studio 2015.

Should I try to find a free version of VS 2010? Should I try to fix the C++
library files so that they work with VS 2015? Is there some other very fast
compiled language, like Fortran, that I should try?

I welcome any advice on how to do this.

Thanks,

Jonathan
