Connect to Quickbase Data from PowerBuilder


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

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

    [email protected];Password=password;Domain=myinstance.quickbase.com;ApplicationToken=bwkxrb5da2wn57bzfh9xn24

    User Authentication Method

    To authenticate with user credentials, specify the following connection properties:

    1. Set the User and Password.
    2. If your application requires an ApplicationToken;, you must provide it otherwise an error will be thrown. You can find the ApplicationToken under SpecificApp > Settings > App management > App properties > Advanced settings > Security options > Manage Application Token.

    User Token Authentication

    To authenticate with a user token, specify the following connection properties:

    1. Set UserToken and you are ready to connect. You can find the UserToken under Quick Base > My Preferences > My User Information > Manage User Tokens.

  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=Id}" Header="Id" Width="SizeToHeader" /> ... </DataGrid.Columns> </DataGrid>
  4. Add a reference to the CData ADO.NET Provider for Quickbase 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.QuickBase.QuickBaseConnection conn conn = create System.Data.CData.QuickBase.QuickBaseConnection(connectionString) System.Data.CData.QuickBase.QuickBaseCommand comm comm = create System.Data.CData.QuickBase.QuickBaseCommand(command, conn) System.Data.DataTable table table = create System.Data.DataTable System.Data.CData.QuickBase.QuickBaseDataAdapter dataAdapter dataAdapter = create System.Data.CData.QuickBase.QuickBaseDataAdapter(comm) dataAdapter.Fill(table) datagrid1.ItemsSource=table.DefaultView

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