hi!
there is an old post with a sample application to display not only google maps but also maps from microsoft ...
the sample code is a liittle bit slow but can serve as a starting point how to use the apis ...

I can confirm that this works. The sample application may be a bit slow but I've tested it and I quite like it.

Strange. Mine still works. I just tested it. You need to be able to compile synapse and then compile and add the MapViewer package. Mind you, your Lazarus version is a bit dated. Maybe that is why it is not working (I'm not sure, just a suggestion).

httpsend is in httpsend.pas (part of synapse) You will have to add httpsend to your uses clause.
