How To: Live Search 101
I have recently started playing with some of the Live Services available at http://dev.live.com. There are some pretty interesting Web Services they have been putting together. I started playing with the Live Search Service you can find at http://search.dev.com. The following is a simple example to show how to use this service with VB.
Before using this you will need to get a developer token at http://search.live.com/developer.
This is required for the example.
In this example we will create a very simple Windows form application that uses the Live Search Service.
1. Create a new Windows form application that contains the following controls named as shown
2. In the code behind BTNSearch enter the following code
Private Sub BtnSearch_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles BtnSearch.Click
If TxtSearch.Text = "" Then
MsgBox("Please Enter a search string")
Dim searchRequest As New com.msn.search.soap.SearchRequest
Dim NewRequest(0) As com.msn.search.soap.SourceRequest
NewRequest(0) = New com.msn.search.soap.SourceRequest
NewRequest(0).Source = com.msn.search.soap.SourceType.Web
NewRequest(0).ResultFields = com.msn.search.soap.ResultFieldMask.All
searchRequest.Query = TxtSearch.Text
searchRequest.Requests = NewRequest
' Replace with your own developer ID from http://search.live.com/developer
searchRequest.AppID = "XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX"
searchRequest.CultureInfo = "en-US"
Dim SearchService As New com.msn.search.soap.MSNSearchService
Dim SearchResponse As New com.msn.search.soap.SearchResponse
SearchResponse = SearchService.Search(searchRequest)
.AutoGenerateColumns = True
.DataSource = SearchResponse.Responses(0).Results
.AutoSizeRowsMode = DataGridViewAutoSizeRowsMode.DisplayedCellsExceptHeaders
' Set the DataGridView control's border.
.BorderStyle = BorderStyle.Fixed3D
When the application is run it looks like the following
The Live Search guys have done a great job in providing an interactive SDK that you can find at http://dev.live.com/livesearch/sdk/ . This SDK provides some pretty cool examples and additional information around using these API’s.
