This article demonstrates how to access WordPress data from Appeon PowerBuilder using the CData ADO.NET Provider for WordPress.
This article demonstrates using the CData ADO.NET Provider for WordPress 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 WordPress to perform reads and writes.
- In a new WPF Window Application solution, add all the Visual Controls needed for the connection properties. Below is a typical connection string:
Url=http://www.yourwordpresshost.com;InitiateOAuth=GETANDREFRESH
To connect to WordPress, set the URL property and other authentication properties. WordPress supports Basic (User and Password) and OAuth2.0 authentication, though Basic is recommended for a testing environment only. To connect with OAuth you will need to register an app with WordPress.
See the Getting Started guide in the CData driver documentation for more information.
- Add the DataGrid control from the .NET controls.
-
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>
- Add a reference to the CData ADO.NET Provider for WordPress 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.WordPress.WordPressConnection conn
conn = create System.Data.CData.WordPress.WordPressConnection(connectionString)
System.Data.CData.WordPress.WordPressCommand comm
comm = create System.Data.CData.WordPress.WordPressCommand(command, conn)
System.Data.DataTable table
table = create System.Data.DataTable
System.Data.CData.WordPress.WordPressDataAdapter dataAdapter
dataAdapter = create System.Data.CData.WordPress.WordPressDataAdapter(comm)
dataAdapter.Fill(table)
datagrid1.ItemsSource=table.DefaultView
The code above can be used to bind data from the specified query to the DataGrid.
