I just can't seem to get this working. The sticking point still seems to be the start_() function.
I am using Labview 10.0, Google Earth 6.0.0.1735, with the plugin version 1.007. The default indicator values are what I get when I run it.
With the attached VI, the getApiVersion method works.
The setDiv_ method appears to work when the WebBrowser is passed and auto-converted to a variant, as the getDiv_ returns a variant with sensible data when converted back to a WebBrowser reference.
The getJavascriptInitCode_ method returns an almighty mess of javascript code, there may be some clues in that for those who 'know'
The getPluginVersion method returns the 6.0.0.1735 string, which is to be expected. The getEarthVersion method returns 'uninitialized'.
This what the API reference
http://code.google.com/apis/earth/documentation/reference/interface_g_e_plugin.html#a101705622bec3df...
states:
| string GEPlugin.getEarthVersion |
( |
|
) |
|
Used for debugging purposes; if this value is not equal to the value
returned by getPluginVersion then there is a misconfiguration on the
end user's system. This check is automatically done during plugin
instantiation.
Now the start_() function appears to be related to the google.earth.createInstance function, which has optional parameters for database and language. When you select the start_ function in a Labview activeX invoke node it automatically puts up the database and language inputs. Wiring empty strings does not work for me, and of course wiring nothing to either of them gives an error. For some reason it seems to work better with the quotes around 'en', that is, it just doesn't work rather than throwing an error. But really, I have no idea. The database string comes from this page:

If someone can get this working, we would all be well on our way to developing standalone applications like Monster Milktruck (google it - it is really cool. And pretty much what I want to do - driving around the earth, but with a custom USB device controlling rather than the keyboard. And the javascript source code is available (right click, show page source) , which may help get it working in Labview. I have successfully copied all the source code over to my PC and have the javascript running locally with a bit of tweaking). All the methods and properties of this activeX class are documented on the google website. I'm sure we are close.
