Hello!
I'm doing a matlab function which control google earth through google api. I get the conexion with the server(becaus I can control the position,camera...) but I want to use the method ShowDescriptionBalloon, and I don't know how.
I've tried :

gE = actxserver ('googleearth.ApplicationGE');
gE.ShowDescriptionBalloon()

but I get this error:
No method 'ShowDescriptionBalloon' with matching signature found for class 'COM.googleearth_ApplicationGE'.

How can I use the method??

thanks!

I believe that's correct; if this is class you're using:

http://earth.google.com/comapi/interfaceIApplicationGE.html

it does not have a public member function named ShowDescriptionBalloon that 
accepts 0 inputs.  You need to pass as input to this method the feature for 
which you want to show the description.  [I haven't used this COM API before 
so I do not have any examples to show you nor do I know specifically how to 
create such a feature object.]

Thank you for replying.
That is other other problem I've got,I have tried to create a feature object like this
gE2 = actxserver('googleearth.FeatureGE');
And appearly the object is created,but then I can not modify or use it...
