• Windows Live Developer Forums WPF (Sparkle) overlays in 3D virtual earth

  Ultimately, we would like to be able to go way beyond simple polyline overlays on maps. I.e. we would like to be able to bring the full power of WPF interactive (sparkle) animated graphic embedded in the 3D space of Virtual Earth. (all geo-located). In addition we would love to be able to download all textures and tiles for a region and work off-line. Of course, this is not possbile yet, But how close are things and what can we fake or mock up to get close to this 1. Can we host the control in a WPF application (outside of IE ) 2. Can we find out the camera vector and bounds of the display region 3. Can we get events and updates when the camer shifts 4. If so we might be able to apply our own 3D overlays on top of the map ...Show All

• Visual C# Using the IS operator in a FOREACH loop

  I am either not understanding how the IS operator works or how the FOREACH loop works. I found some C# code that creates 1 object of 4 different derived classes (see code below). Those 4 objects are assigned to variables of an array of the "base class" type. A FOREACH is used to iterate the array. The FOREACH variable is the "base class" type also. In the FOREACH loop, the IS operator is used to find the object that is specifically one of the four derived types. Here is my question... Since the FOREACH variable is a "base class" type how can the IS ever evaluate to true since the type it is being compared to is a "derived class" type What am I missing Given: Class Employee - An abstract ...Show All
