Public Sub Search(
    keyword As String,
    location As String
)

Parameters

Name	Type	Description
keyword	String	A String containing information to search on a map. This string can contain either geographical names or any other information to look for.
location	String	A String specifying the location near which it is necessary to search for the specified keyword.

Example

To manually generate map items for received GIS data, do the following.

• Set the InformationDataProviderBase.GenerateLayerItems property to false.
• Handle the Geocode data received event of the Bing geocode data provider (BingSearchDataProvider.SearchCompleted).
• In the event handler, implement map item generation based on information stored in the SearchRequestResult.SearchResults array of LocationInformation objects.
