Uses of Virtual Earth SDK
Virtual earth SDK is a superb medium to find out the exact locations that you want. Virtual earth SDK provides users many choices through which they can search relevant data. With virtual earth SDK, they can even display this data on map. If they want to search any kind of information then they can add a find control in their map, which is a wonderful and simple to use method. Adding a find control in a map can give the ability to find out different kinds of addresses and business within short period. At the upper right corner of the map, they will obtain what/where box, where they can see two categories such as location and business. In these two categories, they need to insert the name of location or business that they want to search. After completing this process, they will obtain the expected results, which will appear, on the map. This map can display the detail information about the location as well as business that they have inserted.
When users move the map, they observe that search refreshes itself for suggested area in automatic way. Behind the scenes, the virtual earth map control employs AJAZ to call Microsoft servers, and make search against the huge directory, which include yellow pages. This directory is full of virtual earth maps. However, we observe that Find control is very easy and powerful to make use of but there are few limitations on using this find control method.
If you want to customize the find search results then by capturing the resulting pushpins in a VEShapeLayer, you are able to customize it. Once your results are saved in layer then it is possible for you to turn on and off search results using hide methods, and show methods. You cannot perform more things by making use of this find method until resort to callbacks as well as custom code. Another way to find information is you can capture the results and then process these results before displaying them to different users. By making use of find method, displaying various pushpins for every search is possible. Moving the map in search result automatically is possible and displaying search results in the list is possible. All these things you are able to do by using callbacks. Always remember one thing that Find method is asynchronous. By using callback, you will become free to do anything with results.
These limitations are find control is very hard to change and virtually not stimulating. The other limitation to use this find control method is when you put an ambiguous location, there displays one disambiguation dialog window. In addition, when you turn off this window, you will get unexpected results. So in order to avoid this disturbance, you can make use of find method. This find method accepts various parameters, which include properties like what and where. These properties of find method look like fields of find control. By going through a method of what, the map inserts pushpins for searched location automatically.
