Re: Errors in TypeBrowser generated code

Hi Josh,

Yep, please consider this me "yelling"!!

I would really appreciate help, as I'm a novice with COM.

How do I go about figuring out what Java source is required?  I have C++
examples of how to call this, and obviously know what the method should
do - but not sure how to link the 2 with Jawin.

By the way, do you have any comments on my later email about the dll not
being installed?  After further reading, these methods are the
only "exported functions", and are used to create/destroy the Engine -
after that methods are just called on this singleton Engine object.

Thanks,

David
