Connect to LinkedIn Ads Data from PowerBuilder via ADO.NET

This article demonstrates using the CData ADO.NET Provider for LinkedIn Ads 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 LinkedIn Ads 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:

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

   LinkedIn Ads uses the OAuth authentication standard. OAuth requires the authenticating user to interact with LinkedIn using the browser. See the OAuth section in the Help documentation for a 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=VisibilityCode}" Header="VisibilityCode" Width="SizeToHeader" />
   		...
   	</DataGrid.Columns>
   </DataGrid>
   

4. Add a reference to the CData ADO.NET Provider for LinkedIn Ads 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.LinkedInAds.LinkedInAdsConnection conn 
conn = create System.Data.CData.LinkedInAds.LinkedInAdsConnection(connectionString)

System.Data.CData.LinkedInAds.LinkedInAdsCommand comm 
comm = create System.Data.CData.LinkedInAds.LinkedInAdsCommand(command, conn)

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

System.Data.CData.LinkedInAds.LinkedInAdsDataAdapter dataAdapter
dataAdapter = create System.Data.CData.LinkedInAds.LinkedInAdsDataAdapter(comm)
dataAdapter.Fill(table)	
datagrid1.ItemsSource=table.DefaultView

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