Connect to Reckon Accounts Hosted Data from PowerBuilder via ADO.NET

This article demonstrates using the CData ADO.NET Provider for Reckon Accounts Hosted 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 Reckon Accounts Hosted 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:

   SubscriptionKey=my_subscription_key;CountryVersion=2021.R2.AU;CompanyFile=Q:/CompanyName.QBW;User=my_user;Password=my_password;CallbackURL=http://localhost:33333;OAuthClientId=my_oauth_client_id;OAuthClientSecret=my_oauth_client_secret;InitiateOAuth=GETANDREFRESH;

   The connector makes requests to Reckon Accounts Hosted through OAuth. Specify the following connection properties:

   • SubscriptionKey: Required. You get this value when you created your developer account.
   • CountryVersion: Defaults to 2021.R2.AU.
   • CompanyFile: Required. The path to the company file.
   • User: Required. The username of the company file.
   • Password: Required. The password of the company file.
   • InitiateOAuth: Set this to GETANDREFRESH to let the driver handle access tokens.
   • CallbackURL: The redirectURI of your Custom OAuth App.
   • OAuthClientId: The client id of your Custom OAuth App.
   • OAuthClientSecret: The client secret of your Custom OAuth App.

   CData provides an embedded OAuth application that simplifies OAuth desktop authentication. See the Help documentation for information on other OAuth authentication methods (web, headless, etc.), creating custom OAuth applications, and reasons for doing so.

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=Name}" Header="Name" Width="SizeToHeader" />
   		...
   	</DataGrid.Columns>
   </DataGrid>
   

4. Add a reference to the CData ADO.NET Provider for Reckon Accounts Hosted 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.ReckonAccountsHosted.ReckonAccountsHostedConnection conn 
conn = create System.Data.CData.ReckonAccountsHosted.ReckonAccountsHostedConnection(connectionString)

System.Data.CData.ReckonAccountsHosted.ReckonAccountsHostedCommand comm 
comm = create System.Data.CData.ReckonAccountsHosted.ReckonAccountsHostedCommand(command, conn)

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

System.Data.CData.ReckonAccountsHosted.ReckonAccountsHostedDataAdapter dataAdapter
dataAdapter = create System.Data.CData.ReckonAccountsHosted.ReckonAccountsHostedDataAdapter(comm)
dataAdapter.Fill(table)	
datagrid1.ItemsSource=table.DefaultView

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