Connect to Google Search Results from PowerBuilder via ADO.NET

This article demonstrates using the CData ADO.NET Provider for Google Search in PowerBuilder, showcasing the ease of use and compatibility of these standards-based controls across various platforms and development technologies that support Microsoft .NET, including Appeon PowerBuilder.

This article shows how to create a basic PowerBuilder application that uses the CData ADO.NET Provider for Google Search to retrieve data.

1. In a new WPF Window Application solution, add all the Visual Controls needed for the connection properties. Below is a typical connection string:

   CustomSearchId=def456;ApiKey=abc123;

   To search with a Google custom search engine, you need to set the CustomSearchId and ApiKey connection properties.

   To obtain the CustomSearchId property, sign into Google Custom Search Engine and create a new search engine.

   To obtain the ApiKey property, you must enable the Custom Search API in the Google API Console.

2. Add the DataGrid control from the .NET controls.
3. Configure the columns of the DataGrid control. Below are several columns from the Account table:

   <DataGrid AutoGenerateColumns="False" Margin="13,249,12,14" Name="datagrid1" TabIndex="70" ItemsSource="{Binding}">
   <DataGrid.Columns>
    <DataGridTextColumn x:Name="idColumn" Binding="{Binding Path=Id}" Header="Id" Width="SizeToHeader" />
    <DataGridTextColumn x:Name="nameColumn" Binding="{Binding Path=Title}" Header="Title" Width="SizeToHeader" />
   		...
   	</DataGrid.Columns>
   </DataGrid>
   

4. Add a reference to the CData ADO.NET Provider for Google Search assembly.

Connect the DataGrid

Once the visual elements have been configured, you can use standard ADO.NET objects like Connection, Command, and DataAdapter to populate a DataTable with the results of an SQL query:

System.Data.CData.GoogleSearch.GoogleSearchConnection conn 
conn = create System.Data.CData.GoogleSearch.GoogleSearchConnection(connectionString)

System.Data.CData.GoogleSearch.GoogleSearchCommand comm 
comm = create System.Data.CData.GoogleSearch.GoogleSearchCommand(command, conn)

System.Data.DataTable table
table = create System.Data.DataTable

System.Data.CData.GoogleSearch.GoogleSearchDataAdapter dataAdapter
dataAdapter = create System.Data.CData.GoogleSearch.GoogleSearchDataAdapter(comm)
dataAdapter.Fill(table)	
datagrid1.ItemsSource=table.DefaultView

The code above can be used to bind data from the specified query to the DataGrid.
