Connect to Amazon Marketplace Data from PowerBuilder via ADO.NET

This article demonstrates using the CData ADO.NET Provider for Amazon Marketplace 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 Amazon Marketplace 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:

   AWS Access Key Id=myAWSAccessKeyId;AWS Secret Key=myAWSSecretKey;MWS Auth Token=myMWSAuthToken;Seller Id=mySellerId;Marketplace=United States;

   To connect to the Amazon Marketplace Webservice (MWS), AWSAccessKeyId, MWSAuthToken, AWSSecretKey and SellerId are required. You can optionally set the Marketplace property. For more information on obtaining values for these properties, 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=AmazonOrderId}" Header="AmazonOrderId" Width="SizeToHeader" />
   		...
   	</DataGrid.Columns>
   </DataGrid>
   

4. Add a reference to the CData ADO.NET Provider for Amazon Marketplace 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.AmazonMarketplace.AmazonMarketplaceConnection conn 
conn = create System.Data.CData.AmazonMarketplace.AmazonMarketplaceConnection(connectionString)

System.Data.CData.AmazonMarketplace.AmazonMarketplaceCommand comm 
comm = create System.Data.CData.AmazonMarketplace.AmazonMarketplaceCommand(command, conn)

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

System.Data.CData.AmazonMarketplace.AmazonMarketplaceDataAdapter dataAdapter
dataAdapter = create System.Data.CData.AmazonMarketplace.AmazonMarketplaceDataAdapter(comm)
dataAdapter.Fill(table)	
datagrid1.ItemsSource=table.DefaultView

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