Convert Java to FWH 2011.08

[cdmmaui]

Hello,

I have two code snipets that I need converted to FWH, can someone help convert for me? I am happy to pay someone for their time. Please send me an e-mail at Darrell.Ortiz AT cdmsoft.com if you are interested.

Thank you,

I think straigt converting Java to xBase-syntax will be hard.
I found a Tool converting Java to C++.
C++ You can include in Your App.

Maybe it works for You.
You can try without risk, before buy.
The Demo accepts Lines enaugh, converting Your Function.
