Hi,
I'm trying to control a robot which has a gps, with Google Earth on PC.

I'm trying write PC station with C#. I can embed the Google earth to my form, also I can create a KML document.

But I can't placemark in my form. If Ican placemark, I will say to robot you are here, and you will go there... How Ican placemark? Have you got any API ?

Thanks in advance...
