Connect to HCL Domino Data from PowerBuilder


This article demonstrates how to access HCL Domino data from Appeon PowerBuilder using the CData ADO.NET Provider for HCL Domino.

This article demonstrates using the CData ADO.NET Provider for HCL Domino 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 HCL Domino 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:

    Server=https://domino.corp.com;Database=names.nsf;Port=3002;SSLClientCertType=PEMKEY_FILE;SSLClientCert=full_path_of_certificate.pem;SSLServerCert=*

    Prerequisites

    The connector requires the Proton component to be installed. Normally, Proton is distributed as part of the AppDev pack. See the HCL documentation for instructions on acquiring and installing Proton or the AppDev pack.

    Once the Proton service is installed and running, you will also need to create a user account and download its Internet certificate. This certificate can be used to set the connector certificate connection properties.

    Authenticating to Domino

    • Server: The name or IP address of the server running Domino with the Proton service.
    • Port: The port number that the Proton service is listening on.
    • Database: The name of the database file, including the .nsf extension.
    • SSLClientCertType: This must match the format of the certificate file. Typically this will be either PEMKEY_FILE for .pem certificates or PFXFILE for .pfx certificates.
    • SSLClientCert: The path to the certificate file.
    • SSLServerCert: This can be set to (*) if you trust the server. This is usually the case, but if you want to perform SSL validation, you may provide a certificate or thumbprint instead. See the documentation for SSLServerCert for details.

    Additional Server Configuration

    The connector supports querying Domino views if any are defined. Before views can be queried by the connector they must be registered with the design catalog.

    Please refer to the Catalog Administration section of the AppDev pack documentation for details on how to do this.

  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 HCL Domino 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.Domino.DominoConnection conn conn = create System.Data.CData.Domino.DominoConnection(connectionString) System.Data.CData.Domino.DominoCommand comm comm = create System.Data.CData.Domino.DominoCommand(command, conn) System.Data.DataTable table table = create System.Data.DataTable System.Data.CData.Domino.DominoDataAdapter dataAdapter dataAdapter = create System.Data.CData.Domino.DominoDataAdapter(comm) dataAdapter.Fill(table) datagrid1.ItemsSource=table.DefaultView

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