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