About COM programming

[talun]

Good morning to all,

I would like to start to use the Ebasic COM capabilities but I need, if possible, of a help.

If I don't have misunderstood the help file, Ebasic allows two different approaches of COM programming, one with interface declaration and one without (script syntax).

Now my questions:

What is the more efficient method (interface/script syntax) in term of speed and resources ?

What is the syntax for the objects definition by using the script syntax approach? By studying the examples as that for Sapi.Voice, it seems to me that I need to use a COM browser (as that for Aurora written by Jose Roca), but I don't know if the browser listing needs a conversion for Ebasic and above all, I've not fully understood how as I can get the correct objects definition.

I've also googled the web, with muddling results.

Can someone help me?

thanks! 

Sergio

Hi !

I like the new way to use COM via DispHelper interface.  I just received an ADC board from Emant, and I had everything working in half an hour!
