问题 I have two HTC phones, one is HTC desire and another is HTC aria. I'm using ddms to capture the screenshot on HTC desire before, it works fine.

问题 Using MVC3, C#, and the Razor View Engine: I have a form that has an Ajax Action link. In the options I'm trying to specify OnBegin and OnComplete javascript function calls.

My location value always equals null, and never receives a value. if (location != null) { lat = (int) (location.getLatitude() * 1E6); longi = (int) (location.getLongitude() * 1E6); GeoPoint ourLocation = new GeoPoint(lat, longi); OverlayItem overlayItem = new OverlayItem(ourLocation, "AYO", "Whats good yo"); CustomPinpoint custom = new CustomPinpoint(d, CampusMap.this); custom

That may sound weird but what I was trying to do is that in my app for iOS i want to draw the excursion routes that a specific hotel offers, however all the posts i found so far were focusing on existing roads, since the excursions go through forests, over rivers etc. there are no roads to help me.
