Connect to Google Directory Data from PowerBuilder



This article demonstrates how to access Google Directory data from Appeon PowerBuilder using the CData ADO.NET Provider for Google Directory.

This article demonstrates using the CData ADO.NET Provider for Google Directory 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 Directory to perform reads and writes.

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

    OAuthClientId=MyOAuthClientId;OAuthClientSecret=MyOAuthClientSecret;CallbackURL=http://localhost;InitiateOAuth=GETANDREFRESH

    Google uses the OAuth authentication standard. You can authorize the data provider to access Google Spreadsheets as an individual user or with a Google Apps Domain service account. See the Getting Started section of the data provider help documentation for an authentication guide.

  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=Id}" Header="Id" Width="SizeToHeader" /> ... </DataGrid.Columns> </DataGrid>
  4. Add a reference to the CData ADO.NET Provider for Google Directory 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.GoogleDirectory.GoogleDirectoryConnection conn conn = create System.Data.CData.GoogleDirectory.GoogleDirectoryConnection(connectionString) System.Data.CData.GoogleDirectory.GoogleDirectoryCommand comm comm = create System.Data.CData.GoogleDirectory.GoogleDirectoryCommand(command, conn) System.Data.DataTable table table = create System.Data.DataTable System.Data.CData.GoogleDirectory.GoogleDirectoryDataAdapter dataAdapter dataAdapter = create System.Data.CData.GoogleDirectory.GoogleDirectoryDataAdapter(comm) dataAdapter.Fill(table) datagrid1.ItemsSource=table.DefaultView

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