Connect to Salesforce Data Cloud Data from PowerBuilder via ADO.NET

This article demonstrates using the CData ADO.NET Provider for Salesforce Data Cloud 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 Salesforce Data Cloud 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:

   InitiateOAuth=GETANDREFRESH;

   Salesforce Data Cloud supports authentication via the OAuth standard.

   OAuth

   Set to OAuth.

   Desktop Applications

   CData provides an embedded OAuth application that simplifies authentication at the desktop.

   You can also authenticate from the desktop via a custom OAuth application, which you configure and register at the Salesforce Data Cloud console. For further information, see Creating a Custom OAuth App in the Help documentation.

   Before you connect, set these properties:

   • : GETANDREFRESH. You can use to avoid repeating the OAuth exchange and manually setting the .
   • (custom applications only): The Client ID assigned when you registered your custom OAuth application.
   • (custom applications only): The Client Secret assigned when you registered your custom OAuth application.

   When you connect, the driver opens Salesforce Data Cloud's OAuth endpoint in your default browser. Log in and grant permissions to the application.

   The driver then completes the OAuth process as follows:

   • Extracts the access token from the callback URL.
   • Obtains a new access token when the old one expires.
   • Saves OAuth values in so that they persist across connections.

   For other OAuth methods, including Web Applications and Headless Machines, refer to the Help documentation.

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=[Account ID]}" Header="[Account ID]" Width="SizeToHeader" />
   		...
   	</DataGrid.Columns>
   </DataGrid>
   

4. Add a reference to the CData ADO.NET Provider for Salesforce Data Cloud 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.SalesforceDataCloud.SalesforceDataCloudConnection conn 
conn = create System.Data.CData.SalesforceDataCloud.SalesforceDataCloudConnection(connectionString)

System.Data.CData.SalesforceDataCloud.SalesforceDataCloudCommand comm 
comm = create System.Data.CData.SalesforceDataCloud.SalesforceDataCloudCommand(command, conn)

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

System.Data.CData.SalesforceDataCloud.SalesforceDataCloudDataAdapter dataAdapter
dataAdapter = create System.Data.CData.SalesforceDataCloud.SalesforceDataCloudDataAdapter(comm)
dataAdapter.Fill(table)	
datagrid1.ItemsSource=table.DefaultView

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